Ovid’s data look flimsy.

Opdivo and Keytruda are approved in China. CStone and countless others are in pivotal trials. AstraZeneca has a long history in China and you can bet will register Imfinzi there. I’m not sure what Roche’s or Pfizer’s ambitions are, but they also do strong business in China and have globally registered PD-1s. So there are at least 6 PD-1 mabs I can name off the top of my head that are China-approved or likely to be that do not come from Beigene. But Beigene has a very large market capitalization. This will not persist. I have not seen something like this in a long time.

Lots of interesting companies to look at. Constellation, Summit, Fibrogen and so many more. Not enough hours in the day!

Is the world ready for biosimilar orphan drugs? Cerezyme and Myozyme aren’t tiny. I guess we have a few “me-toos” but they’re not cheaper.

Interesting article in JAMA my father sent me on body dysmorphic disorder and social media photo editing software as a trigger for this disorder. BDD is real: if you’ve ever seen someone with large amounts of plastic surgery, they likely suffer from BDD. But there are plenty of people who suffer quietly. Most people are probably unconsciously affected by societal progression of beauty standards. There’s a reason I’m attracted to Lindsay Pelas and Jen Selter–it’s mostly because I’m a man and they largely embody deeply inherited/evolutionary desires of man. So what if they understand that and have perfected it? We’ve reached the singularity of female desirability and the technology-enabled enhancement (both photographical and biological) of it. What’s next? I don’t know.

Always study the history of the industry you’re following. For biopharma, be familiar with companies like Cetus, Chiron, MedImmune, Centocor, Immunex, HGS, Genentech, Genzyme, Idec, Millennium, ICOS, Vicuron, Athena, Genta, Sugen, Warner-Lambert, Pharmacia, Syntex, Abgenix, Triangle, CV Therapeutics, Pharmion, Sandoz, Ciba-Geigy, RPR, ICI, Aventis, Parke-Davis, Scios, COR, Imclone, Medarex, Atherogenics, Telik, Tularik, Intermune, Elan, Northfield, Vion, GenVec, Cell Genesys, Pharmasset, Idenix, ViroPharma, NPS, Myogen, MGI, OSI, Synta, Trimeris, TKT, Aviron, GI, Tanox, and so many more. There is some wisdom in history. You have to mine for it, distill it.

Papers I’ve Read
Functional gamma-secretase inhibitors reduce beta-amyloid peptide levels in brain. Dovey et al. J Neurochem 2001.
I guess this Elan/Lilly paper started the whole semagacestat/gamma-secretase mess. They go up to 200mg/kg (!!!) dosing in these experiments with their putative GS inhibitor DPAT. Its very hard to trust any of the data given what we know now about APP processing and intracellular retention. Still, you can see the errors in judgment with the high-powered lens of hindsight. It’s also funny to see what passed for a screen in 2001.

The gamma-secretase inhibitor N-[N-(3,5-Difluorophenacetyl)-L-alanyl]-S-phenylglycine t-butyl ester Reduces AB Levels in Vivo in Plasma and Cerebrospinal Fluid in Young (Plaque-Free) and Aged (Plaque-Bearing) Tg2576 Mice. Lanz et al. JPET 2003, 305:864-871.
Pharmacia workers “replicate” Dovey. Same issues. I think everyone was okay with the 100-200mg/kg dose given low brain partitioning and a cell-based assay affinity of ~100nM. It’s really hard to tell what these ELISAs are picking up and what species are relevant for aggregation.

I’ve received around 500 books by mail since I entered the prison system. There is a Twilight Zone episode, “Time Enough At Last” (I think that’s what it is called!), that summarizes my feelings on having a lot of time to read. It’s a joy, but I don’t exactly have the shelf space. I probably have around 50 books here at Fort Dix. This is still far too many. So, please don’t send me any books without my knowledge! They will probably end up donated or thrown away. Also, if you mail me, it must be in a plain white envelope with plain white paper. No stickers, glitter, or contents other than paper. No stamps.

Sarah Jeong joining the New York Times is a disgrace. This woman is not a satirist, she has truly backward and painful racial beliefs. We should ask her some simple questions to clear up her “satire”. If you did the same to me, it would look like this:

Q. What do you really think of Hillary Clinton?
A. I think she is an untrustworthy parasite of politics. She should not hold office and represents what is wrong with the American political system.

Q. But why?
A. Just look at how much money her family has made through “speeches”. That’s basic influence peddling. I don’t expect Bill Clinton to become a store clerk after being President, but to become a high-paid lobbyist is a bit disgusting. They’re certainly allowed to be capitalists, but the irony of HRC railing against the rich is not unnoticed.

Q. Do you wish harm on the Clintons?
A. No. I admire all Presidents, once elected. As someone who has achieved a lot, the Presidency is the ultimate achievement and I respect the winner of such an arduous contest. I haven’t yet seen a President so contemptuous to break this ingrained respect. I also begin my analysis of a candidate with a “clean slate”, once elected. I would have done the same for Hillary.

If you did that with Sarah Jeong I think she’d have a hard time disavowing some fairly extreme views. I’d like to see the demographics of the New York Times staff and its readership. I wonder if “white people” are high on that list. I also want to remind Ms. Jeong that Asian Americans are now the highest earners in the United States. There are a lot of poor, uneducated and very, very non-privileged white people. Racism is painful and shameful, but society must grow and move on. Never forget, but learn and grow. What is Jeong adding to the conversation?

Always remember that investing is simply price calculations. Your job is to calculate accurate prices for a bevy of assets. When the prices you’ve calculated are sufficiently far from market prices, you take action. There is no “good stock” or “bad stock” or “good company”. There’s just delta from your price and their price. Read this over and over again if you have to and never forget it. Your job is to calculate the price of things and then buy those things for the best price you can. Your calculations should model the real world as thoroughly as possible and be conservative in nature.

Neurocrine is selling a lot of drug. Sometimes you’re wrong! Good for them.

It’s the end of an era for Johnson & Johnson as Stelara takes over Remicade as their best-selling drug. What an achievement, and mostly on psoriasis? Kind of incredible how patients will be diagnosed the more a treatment is effective. Build it and they will come!?

I’m going to start including “Patents I’ve Read”, as a very important source of knowledge that I try and keep up with.

Papers I’ve Read
Computation through Cortical Dynamics. Driscoll et al. Neuron 2018.
This… this is a paper on computer science? 10-dimensional data can’t be visualized? Hold my beer.

Hearing out Ultrasound Neuromodulation. Airan and Pauly. Neuron 2018.
Funky ideas debunked. Ultrasound evokes an auditory response even at inaudible frequencies. Probably useless for neuromodulation.

Noninvasive blood tests for fetal development predict gestational age and preterm delivery. Ngo, Quake, et al. Science 2018, 360, 1133-1136.
Dr. Quake out with another banger. Drake should take notes. The cell-free fetal RNA test looks at the mother’s blood to determine delivery date. It’s as effective as ultrasound, which was a little disappointing, but my guess is it will be optimized. Pretty amazing!

Subclinical Hyperthyroidism. Biondi & Cooper. NEJM 2018.
Just in case you needed to know about a disease with no symptoms or sequelae.

Reboxetine in therapy-resistant enuresis – a randomized placebo-controlled study. Lundmark et al. J Pediatric Urology 2016.
If you’re old enough to remember Pfizer developing a reboxetine isomer, good for you. The problem with bringing reboxetine to the US is you have atomoxetine which is functionally similar (and generic). So, you could spend a lot of money “repurposing” reboxetine for ADHD, enuresis, NOH or god knows what else, and probably do just fine, but I don’t do just fine, do I?

Chronic delta9-THC in rhesus monkeys: effects on cognitive performance and dopamine D2/D3 receptor availability. John et al. JPET 2017.
I’m all for getting monkeys high and seeing what happens. Apparently you develop a tolerance to some cognitive impairment and whatever else goes away after two weeks of abstinence. Legalize away!

Long has paled that sunny sky;
Echoes fade and memories die,
Autumn frosts have slain July.

You can imagine how surprised I was to receive a book from “Ringo” today. Ringo is a member of the canine species, and said member unfortunately lacks a uniform color. Nevertheless, despite his polychromicity and limited intellect, he successfully mailed me “Quantum Physics of Atoms, Molecules, Solids, Nuclei and Particles by Eisberg and Resnick”. This is a subject I know little of and hope to know even less. It will fit snugly on a planck under my bed until Ringo learns how to respect members of the feline species. Jokes aside, thanks you Ringo. May you outlive your namesake.

Well, Yescarta is doing quite well, actually. $68m last quarter as per Gilead’s most recent quarterly earnings. That’s not awful! This is one-time treatment, however. So unlike most drugs, these patients aren’t paying a subscription fee. For Gilead that kind of reminds me of hepatitis C, but of course, unlike HCV, cancer patients don’t come from a “pool”, they simply arrive every year. It’s far too early to tell but generally a performance like this would suggest a $1 billion medicine, at least. Makes KITE a decent deal. However, as in all things, you can never know for sure. Next quarter could be down! The drug may plateau at $500 million or go on to $2 billion+ performance. No idea.

Surprised how well ABBV is holding up in Hep C.

It is still fascinating to me that drug journalists not only are unfamiliar with statistics, but they also appear to be rooting for drug companies to do poorly. The hatred towards AbbVie for not having biosimilars in the US is particularly funny. Are these writers taking Humira for rheumatoid arthritis? Do they think that biosimilars to adalimumab, which represents ~2% of US drug spend will save what they perceive is a healthcare crisis? Have they looked at AbbVie’s patents and have pointed out the prior art that renders them meaningless despite the respect shown by the biosimilar companies? Emotion trumps inference for the cognitively challenged.

Papers I’ve Read
Semagacestat Is a Pseudo-Inhibitor of gamma-secretase. Tagami et al. Cell Reports 2017:21, 259-273.
Tagami and Shionogi workers go on an interesting journey to learn more about gamma secretase. They draw very speculative conclusions but have a foundation: semagacestat INCREASES beta-amyloid intracellularly. So, if you’ve been playing along from last week (and you should), we have to solve a mystery. One solution is a simple law of conservation. If you have a pre-peptide (endothelin, angiotensin are good examples) and it has to be “processed” (cleaved) to create its final form, and you inhibit the enzymes that do this, you still have the pre-peptide (sometimes called a pro-peptide, or even a pre-propeptide.) If that entity aggregates, you’re in trouble. Peptides are eventually proteolytically degraded but if they are aggregation-prone, you’re out of luck. The writers assume semagacestat is inhibiting some other functional part of the GS complex, the part they speculate trafficks AB out of the cell. More work is needed, but it neatly explains all the results seen so far. This is a great lesson in preclinical experimentation: make sure you know what you’re measuring. AB in the “soluble fraction” (extracellular) may drop but if its being retained, you haven’t solved the problem.

Primary Prevention of Cardiovascular Disease with a Mediterranean Diet. Estruch et al. NEJM 2013.
As we close the semagacestat puzzle, here is a new one for young, would-be drug hunters. What do you see in this publication that is strange? Are the conclusions reasonable? Can we reject the null hypothesis? Why not? Answers in the next blog. Guess away in the comments.

Phase 3 Trial of Ibrutinib plus Rituximab in Waldenstrom’s Macroglobulinemia. Dimopoulos et al. NEJM 2018.
The “iNNOVATE” trial demonstrated a death-defying HR=0.20. WM is a weird little disease, often an afterthought given its relatively indolent nature compared to its cousins. Still seems like there could be an opportunity here for another agent.

Dupilumab Efficacy and Safety in Moderate-to-Severe Uncontrolled Asthma. Castro et al. NEJM 2018.
Efficacy and Safety of Dupilumab in Glucocorticoid-Dependent Severe Asthma. Rabe et al. NEJM 2018.
New Biologics for Asthma. Drazen & Harrington. NEJM 2018.
Great data. Asthma is a bigger disease state than folks realize. Very much looking forward to the Dupixent Q2 number.

The last post about intelligence requirements for STEM vs. the humanities was triggering. But, it was a trap! There has been enormous data generated recently that correlate intellect with educational achievement and even SAT performance (high R^2!). I must admit I’m probably going a bit too far when I say learning quantum physics is “harder” (requires more cognitive ability to perform adequately) than gender studies. One can be a master of each discipline. Was Einstein more of a genius than Shakespeare? No, definitely not. Was Shrodinger no less of a luminary than Duca? In all seriousness, I think a well-rounded education is important. I don’t write frequently anymore, but once-upon-a-time I thought I’d do it for a living. My problem with science business (pharmaceuticals, for instance) writers is they don’t know science or business. There are very few people who know both fields, and you can bet they’re not writing about it. Before you bicker about some prevailing inferiority complex, consider the above an advertisement: I’m doing it!

antibody – n – An immune system protein, “Y”-like in shape, composed of Fc and Fv regions. Binds to, and generally eliminates, a target molecule called an antigen, usually another large molecule/protein. Originally manufactured in mice (murine antibodies).
chimeric antibodies – n – Obsolete now, but antibodies created with a human Fc region and mouse Fv region.
complementarity-determining region (CDR) – region of an antibody that defines its binding to its target
consanguinity – adj – Related parents (inbreeding). Very common in rare genetic diseases. A restricted gene pool tends to result in autosomal recessive disease — the Amish, certain Jewish sects and other populations that simply don’t see much migration have a larger share of rare diseases.
epitope – n – exact binding site of antibody’s antigen.
eosinophils – n – a type of white blood cell that mediates an allergic/asthmatic response.
Fc region – n – “Framework constant” region of an antibody. The bottom part of the Y.
fully human antibody – n – generally created in transgenic mice where the mice are genetically modified to only create antibodies from human genes.
Fv region – n – “Framework variable” region of an antibody. The arms of the Y.
Humanized antibody – n – a chimeric antibody with a human CDR framework (much of which is constant).
intent-to-treat – n – for statistical purposes, the entire enrolled trial population, usually that was randomized and received at least one treatment dose. As opposed to per-protocol population, the pool of patients that completed the trial correctly. Test statistics are almost always conducted on the ITT population with missing data interpretation defined prospectively.
monoclonal antibody – n – See antibody. The monoclonal adjective distinguishes from polyclonal, in that monoclonals come from one source and have one epitope.
type 2 inflammatory response / immune response (Th2) – n – Elevated levels of eosinophils, IgE, IL-4, IL-5, IL-9, IL-13 and other immune markers that distinguish the response from Th1.

Alexion is kicking butt. Being this good is almost boring.

Gilead, both Johns are stepping down. Running a big pharma and being that good is boring too, I guess.

Keytruda approved in China. Big problem for Beigene.

BAN2401 is not a viable drug. It does not work. No way, no how. I think people who write about biotech for a living should write less quickly (and less from a company script) and read some textbooks on statistics, medicine and pharmacology. Friends email me news here and I was aghast to see nearly every biotech ‘observer’ pathetically record that BANB2401 produced a promising result. “Stat” (whatever that is), CNBC (predictable), Endpoints (this is that weird guy’s blog), etc. All the usual suspects just don’t know how to read clinical data. Why even try to chronicle the history of an industry if you just don’t get it? Maybe wait until the dust settles before writing an embarassing headline. It is really emblematic of an epidemic: media companies don’t have big budgets, so they hire whoever they can to write whatever they want on a field they don’t comprehend. I saw some financial journalists completely fail to comprehend amortization recently. A silent smile is all I can produce. So, I understand predicting the future is too tough for biotech writers, but at least chronicle the past correctly.

Anyway, the stock market promptly reacted to the BANB2401 data for the failure that it was. Antibodies don’t enter the brain, let alone the cortical areas, the parenchyma, etc. It’s fucking physics. F=MA? Tight junctions? Next, we saw what happens when a-beta antibodies are dosed in AD: bapi, sola, etc. Finally, THIS data is a piece of work. Don’t trust any p>0.01. That is the same as p>0.05. For Christ’s sake, don’t trust data at p>0.01. Drugs don’t work by chance, ever. At least drugs I care about. Next, the idea that one drug dose worked and one didn’t is humorous. Unless you have a clear explanation as to why one dose wouldn’t work and one would, you have to group and average the cohorts. The company wouldn’t waste precious power and resources if they thought there would be no activity in the dose cohort. Most antibodies stick around. It’s plausible that more frequent dosing would do the trick, but unlikely. Same thing with timing of therapeutic effect: the separation that occurs at 18 months has no trace at 12 months. Is there a plausible reason for that? Sure but I’d be more convinced if it persisted at 24 months. Very, very few drugs have a 12 month delayed therapeutic onset. FInally, this isn’t a clinically meaningful result (hence the p=0.016 or whatever it was). ADAS-COG is a 70 point scale. A 2 point improvement is exactly what these antibodies were invented to NOT produce. I’ve wasted enough transistor state changes writing this. I’m sorry, electrons.

Book Review – How Not to Be Wrong: The Power of Mathematical Thinking – Jordan Ellenberg
It’s hard for me to review a book like HNTBW. One lens to look at it through is, “could I have done better”? I’ll go through areas I think were lacking, but this is a paean to math that deserves your attention. Of course, One of Bill Gates’s “10 Favorite Books”, which I’m sure is a subset of a larger list of his favored reads, which is apparently, everything he reads.
The title of this book could not have been written by its author. It is largely meaningless. The title should have been: “My random thoughts on Math and Statistics which will hopefully get you interested in Math”. There is no theme that I could discern other than the author’s obsession with math history. So Ellenberg’s structural organization is very poor. He meanders from topic to topic, staying far too long on some (statistics), ignoring others completely. On the plus side, he is imaginative with references to F Scott Fitzgerald, the erstwhile mathematician Wallace (David Foster!) and various other compelling orthogonals. His actual writing style is excellent. Clearly a keen mind, he restrains himself from overpowering the reader with the standard philosophical/mathematical overwrought vocabulary. “He’s just an average joe math professor!” is the feeling you get and it keeps you engaged.
Ellenberg tries to do a good deed. His message is that this book will somehow help you think more structurally. It won’t do so, directly. There are very few (maybe two?) proofs in the book and other than a brief explanation of reductio ad absurdum, very few logical techniques are actually employed. Despite that, Ellenberg tackles hundreds of problems with a sneaky mathematical armamentarium. I fear his secret spies could have been more direct: on battalion, a little more actual math wouldn’t have scared the reader and empowered the work. Some of HNTBW feels like a parlor trick, with the reader forced to trust Ellenberg that “there’s math in here, don’t worry! I’m not going to show it to you, but it’s there!”.
Understandably HNTBW has a strong focus on statistics but here Ellenberg makes a very poor showing. In the classic example of multiplicity errors gone haywire, Ellenberg introduces the GWAS experiments that yours truly reviews on a daily basis but doesn’t describe p-value correction. This and other glaring omissions, like any discussion of why people insist on making post-hoc observations that fail to repeat themselves, could have served readers well.
The second half of the book is a more poetic journey through math history. While he is no Newman and this is no anthology, Ellenberg’s near lyricism is enchanting and awe-inspiring. The last chapter in the book is a monument to humility, creativity and achievement in maths. Still, HNTBW is not Godel-Escher-Bach, nor does it try to be. Ellenberg just teases us with math, often namedropping greats and taking us on a tour meant to enthrall us and learn more. A much-needed manual on how to actually think in a structurally correct way was a titular trick I’m happy I fell for. I highly recommend this book. 9/10.

Glossary – Dedicated to various journalists at Bloomberg, CNBC, Stat, etc. who I wouldn’t hire to change my cat litter because they apparently are unaware of the following:
a priori – generally used as a synonym for “pre-specified” in statistics.
alpha – the likelihood of making a type I error, or rejecting the null hypothesis when it is true
beta – the likelihood of making a type II error, or incorrectly concluding the null hypothesis is correct
clinical significance – as opposed to statistical significance, the degree to which a medicine is clinically relevant to a patient. 2 points on a 70 point scale, for instance, is not clinically relevant.
co-primary endpoint – if you split alpha a priori, you can examine two endpoints at once. however, both endpoints must be met with the reduced alpha to infer the rejection of ANY null hypothesis.
deductive reasoning – using the rules of logic to form inferences with certain conclusions.
Fisher, Sir Ronald – British statistician who was the father of statistics. Probably the first person you could call a statistician.
Fisher’s Exact Test – A personal favorite, a categorical statistical test for contingency tables.
Gauss, Carl Friedrich – Mathematical deity who the normal distribution is named after
inductive reasoning – find patterns in empirical data. any inference where the premise is giving us some evidence of truth, resulting in a probabilistic inference
inference – something many, many liberal arts majors are incapable of
mechanistic plausibility – The plausibility of an investigational drug’s mechanism of action. Similar drugs having failed to elicit a beneficial response in a similar patient population would impinge negatively on plausibility.
null hypothesis – the hypothesis we seek to invalidate with an experiment, a reductio ad absurdum technique
Pearson, Karl – another father of statistics, see Pearson’s chi-squared test.
p-value – the quantification of statistical significance, where the p-value must be less than alpha.
pre-specified endpoint – Typically, a between-group comparison using a statistical method that is articulated in the SAP prior to trial initiation.
primary endpoint – The ONE a priori statistical test hypothesized in the SAP. A clinical trial can only interrogate ONE hypothesis so as to avoid unduly respecting post hoc observations. IF the primary endpoint is met with statistical significance, a secondary endpoint may be evaluated as per the SAP with the same alpha level as the primary endpoint (no alpha is considered spent). Dose-ranging studies make pre-specified endpoints extremely hard to meet given the limited power of making each dose a co-primary endpoint. One may group all or some doses and retain full alpha, but one may not assign full alpha (0.05) for all doses. If 5 doses are being interrogated, the alpha must be SPLIT between these doses (roughly 0.01 each).
post hoc analysis – An after-the-fact analysis of data which is hypothesis-generating ONLY. Typically used by companies and characters of ill repute to bolster clinical trials which have failed to reach statistical significance. “Shooting an arrow and painting the bullseye after”.
power: 1 – beta
probability distribution: a description of probability of all possible outcomes in an experiment
statistical analysis plan (SAP) – the statistical protocol for a clinical trial
statistical significance – when p < alpha, the probability that the results obtained if the null hypothesis is true, were due to chance
type I error: rejecting a true null-hypothesis
type II error: failure to reject a false null hypothesis

Spend more time reading books and less time giving out an unearned opinion. I doubt many “communications” majors (or most other liberal arts majors) are intelligent enough (yes, I am going there) to have done well in mathematics and statistics. As Dalio says, ask yourself if you’ve earned the right to have an opinion. You should not opine on biopharmaceuticals unless the above is facile and simple to you. Statistics is the lens with which we see the modern data-driven world. Go back to school and actually learn something, if you have to. The above are trivially basic–we don’t go into Bayes vs frequentist, ANOVA, actual math of a statistical test, stratification methods, parameterization, multiplicity correction techniques, LOCF/BOCF and missing data and other still simple topics.

I like Global Blood Therapies’ (GBT) drug. I’m still not through with my work but I suspect this is a real disease-modifying drug that treats the underlying cause of sickle cell anemia. A real breakthrough. This company may become as large as an Alexion or Onyx (pre-takeover) in due time.

CAR-T looks like a commercial dud. Sorry, Celgene and Gilead. Those billions are unlikely to come back. Who knows, though. Antibodies had slow uptake at first. What I’ve heard from various sources is institutions don’t want to do CAR-T. The side effects are tough and the reimbursement is difficult. This is good for companies like Morphosys and Seattle Genetics who are using traditional antibodies for CAR-T targets and some are seeing good results. Bad news for the 200 private CAR-Ts, ADAP, CLLS and everyone else who wants to be JUNO and KITE.

The flu market is heating up with new drugs from Roche, Shionogi and Vertex and some promise of a universal vaccine.

Idorsia is chugging along with their rHTN (resistant hypertension) ERA (endothelin receptor antagonist). Guess who also bought an ERA way back when 😉

Starting to watch the vaccine space very closely. One of the few areas of pharmaceuticals that is truly cost-effective, hard to replicate/genericize, etc. Every new vaccine company seems to get acquired (IDBE, CRXL for you old timers).

Papers I’ve Read
I’ve been reading some proprietary materials, so excuse the lack of commentary.

GBT440 increases haemoglobin oxygen affinity, reduces sickling and prolongs RBC half-life in a murine model of sickle cell disease. Oksenberg et al. Br J Haematology 2016.
Tremendous work from the GBT team here. This panel of preclinical data is comprehensive. Almost every question I would have asked is asked and answered here. The murine transgenic model was a bit of a flop, which was interesting. Nevertheless, GBT440 certainly works as advertised, increasing Hb-O2 affinity, thereby raising the question of whether these HbS-GBT440 complexes are TOO oxygen-hungry and will never release this oxygen to tissues. It would still (or should still) stop polymerization of the aggregation-prone HbS species. One question I would have answered is trying to determine binding kinetics here, especially Koff. Km wouldn’t hurt, we see some EC50s in the micro molar range. The engineering of a compound devoid of plasma binding is somewhat surprising. If I had to decide on buying this whole company, I’d probably run that assay independently to be really sure as it is not often compounds have close to zero albumin affinity.

Clinical activity and molecular correlates of response to atezolizumab alone or in combination with bevacizumab versus sunitinib in renal cell carcinoma. McDermott et al. Nature Medicine 2018.
The IMmotion150 Phase 2 results. Nothing exciting here. Gene expression-guided treatment is a pretty neat concept and shows were Sutent actually does rather well.

New Developments in Anti-Sickling Agents: Can Drugs Directly Prevent the Polymerization of Sickle Haemoglobin in Vivo? Oder, et al. Br J Haematol 2016.
Decent review. Somewhat stunning that there are 20T (trillion!) red blood cells, which are most of your cells (!!!). Each RBC has 250 million (!) hemoglobin proteins. so that is … 2*10^13 X 2.5*10^8 = 5.0*10^21. You need 20% of that hemoglobin ‘fixed’ according to various in vitro studies, so 1.0*10^21. The MW of GBT440 is 337, so the weight of the drug you need is 3.37*10^23. Avogadro’s # is 6.022*10^23. So you need 500mg of GBT440, but the bioavailability of the drug is something like 50%, so you need 1g/day. That’s roughly what they dosed in Phase 3. Incredible!

I received a rather ineluctable haircut after “looking like Harry Potter” (at least to various other convicts) for far too long. One barber agreed to “give me the Brad Pitt” after discussing various style options. Consequently, I have very little hair left. No longer hirsute, life goes on! Just like the memes, barbers here also insist on reciting “say no more, fam” prior to destroying your appearance.

Why does Bill Gates review EVERY trash book and think they’re good? Poor guy. Bridge & reading psychosocial commentary is one helluva retirement. At least his healthcare stuff seems well done. I’ll probably learn how to play bridge soon.

hemolysis (medicine, basic concept) – destruction of a red blood cell (RBC) that lyses the cell membrane and releases its contents
hemolytic anemia (medicine, basic concept) – anemia due to hemolysis
hematocrit (medicine, basic concept) – RBCs as a % of blood
aromatic (chemistry, basic concept) – adj – a compound with the presence of cyclic sigma bonds and non-localized pi bond
pi bond (chemistry, elementary concept) – delocalized bond present in a double bond (in addition to a sigma bond)
sigma bond (chemistry, elementary concept) – overlapping bond present in a single bond
aldehyde (chemistry, basic concept) – a functional group featuring a C=O bond with a R-C and H-C bond.
thiol (chemistry, basic concept) – a functional group consisting of R-S-H

–I left off musing about the inability for public equities to achieve a meaningful risk-adjusted positive return. This is an unorthodox and uncomfortable opinion I have tremendous conviction in. The impact of some of my opinion is derived from explaining the post hoc ergo propter hoc fallacy: folks who disagree with me point to historical returns instead of the underlying structure for what to expect from the future. History is not a guide for the future here, even 100 years of history. The US will never be in the same situation it was then, ever again (scale, globalism). Or there is a framing error: they are looking at US equities only, forgetting there are some failed states that want their stock markets back. I’m sure the Soviets and Japanese thought THEIR stock markets would always go up, too. Aren’t we all lucky to have been born here? Boris Buffetski and Waryu Buffetashi are missing in action. I’ll have more to say, not only on why historical returns for global equities are not that impressive on a real- and tax-adjusted basis, but also why structural flaws will limit future equity returns to very close to zero, if at all positive.

–Still working on the time-consuming Merck analysis. I’ve figured out the classification of all their drugs over the years. However, the vaccines are tricky given some of them have been refreshed for 50+ years! We’ll exclude the vaccine business for our purposes and adjust the R&D a bit. Still, huge hits like Fosamax, Singulair, Januvia and Zocor promise that Merck’s been far more productive than Pfizer. We’ll see what the final calculations say soon.

–Wealth can’t be understood without age-adjusting. Anyone who has read ‘Snowball’ or spent a lot of time thinking about compounding understands this. Getting a good head start is nice, but keeping pace is difficult. I’m going to make a chart of wealth on an age-adjusted and inflation-adjusted basis and run IRR calculations comparing individual wealth as you would corporate. Here’s the work on Buffett:

From 1958 to today, Buffett compounded his personal wealth by about 21.5%, from $1 million to $82 billion. I will try to undo some of his donations and see how he would have done by keeping all his BRK stock. I’m not sure what impact that’s had on his wealth.

At 30, Buffett’s $1 million of wealth is $8.5m in today’s money.
At 35 (my age), Buffett’s then $7 million of wealth would be $56m in today’s money. (So far so good for me!). From this age, Buffett compounded at 19.33%. That’s every year, for the next 53 years. Astounding!

At 43 (year is 1974), gaining steaming, Buffett’s $34m is worth $193m in today’s money. He compounds from 19% from here.

At 52, he’s worth $376 million, in today’s terms, $951 million. A billionaire. From here, he returns 16% per annum.

What’s amazing about WEB is we celebrate billionaires so much in today’s culture (except for CNBC, because they’re nazi socialist/communists), and he was a little late to the party. It shows you that wealth is about longevity and having the right mental framework for long-term success. Buffett whizzed past a lot of early birds with his consistency.

–Finally, a repeated thank you to the management team at Vyera who is delivering all this success for me. Would be nothing without you! Stunning R&D productivity with 4 INDs likely (3 already in the bag!) in just 3 years. May you keep compounding 🙂

Book Review – A Brief History of Time – Stephen Hawking

Dr. Hawking recently passed away and so perhaps he has taken a throne next to Einstein, St. Augustine, Descartes, Pascal and others in a room God marks as “Nice Tries”. Explaining the universe is a tricky avocation. Having ALS at the same time would make one’s job harder. Nevertheless, Hawking made profound advances in theoretical physics and cosmology which he has been duly lauded for. Many pop science writers are unpublished hacks, but Hawking had the scientific chops to straddle both worlds. While his disability made him a celebrity, and one wonders if he would have been as popular without it, or if some researchers secretly resented him for it, we won’t know and shouldn’t care.
About the book!? Right! Well, “A Brief History” is one of the most printed books of all time. It’s that bestseller that everyone has on their bookshelf and no one has read cover to cover. As a preteen/early teen I was a particle physics enthusiast, obsessing over subatomic taxonomy and I STILL didn’t read ABHOT, partially because I felt Hawking was TOO celebrated and partially because of its pop orientation. However, I admit for the early part of this period, I was awed and inspired by this computer-voiced crippled man who could still level you with his mind. And in ABHOT, Hawking does just that.
ABHOT is very far from a textbook, and it is too simplistic and even patronizing in parts (Hawking refers to Kant’s seminal Critique of Pure Reason as “obscure”). However, in general, ABHOT is mostly too difficult to fully understand and appreciate. I challenge the lay person to keep attention during Chapter 8, for instance. “The Origin and Fate of the Universe” is an abstract mess that is hard to follow unless you have an undying curiosity about this field. If this is your first time encountering spin states, the cosmological constant, or even simple quantum mechanics, you will be lost trying to follow this work.
If understanding the universe is a tricky business, then perhaps explaining the universe is even more difficult. I don’t fault Hawking for sometimes deliberately leaving out crucial mathematical details. He goes on to say “well, I proved this” and “this theory requires that” but leaves the reader without evidence of his line of thinking, only his grand authority. I won’t cavil about the published refusing the words billion and trillion, instead relying on “6 million million million”, as if this is an easier concept to understand than scientific notation. Hawking annoyingly explains in parentheses how many zeroes the author is indicating. The book is too short to be useful–at less than 200 pages of the main text, some necessary core concepts are completely eliminated. We’re left with lots of questions about the nature of time, and perhaps that is the point. Hawking drills in over and over again that time is not linear in the sense that we understand it. It likely has no beginning, no end and no absolute measurement. He explains relativity and spacetime reasonably well but he doesn’t evoke the wonder you might expect in such a numinous subject. For the more mundane concepts, the reader will be bored. Do you really care what happened in the femtoseconds after the Big Bang? Hawking forgets his audience with excursions that can sometimes be painful.
Concepts like black holes and radiation they emit are again, far from terrestrial, even in his attempt to ground the subject matter. Advanced readers are simultaneously puzzled and frustrated by a lack of detail and all-too-frequent hand-waving and progression of a concept. A more detailed work would be even drier, and perhaps risk only 0.5% of purchasers reading the book than the current 1.0%. Still, if you’ve have had any exposure to physics, ABHOT is a relatively fun breeze which should rekindle some interest in wonderous entities like gravitational waves and particle colliders. I fondly recall a childhood where I’d exhaust my schoolmate Franky’s patience with latest developments at CERN–to what end are all of these atom smashers annihilating the unseen?
This is where ABHOT fails to become a transcendant work. For all the science, Hawking barely scrapes the philosophical surface. He rhapsodies briefly on the anthropic principle, but largely evades the important question and reason anyone bought this book. Is there a God? Do you see Him in those atom smashers and huge telescopes? A signature perhaps? Anything you can tell us about why we’re here, where we came from and where we’re going? Hawking flirts with the concept of a diety but only when its comfortable and it feels perfunctory and obligatory. Perhaps a new version would have some important updates from the author.

Papers I Read
Proximity to Parental Symptom Onset and Amyloid-Beta Burden in Sporadic Alzheimer Disease. Villeneuve, et al. JAMA Neurol 2018.
This is a very sorry paper. The main finding is r^2=0.08, p=0.04. I don’t see how journals publish stuff like this. Like, I get that you wasted your government or whoever’s grant money and need to show SOMETHING. Write a nice “we’re sorry” card. Don’t publish. Or just say you found no correlation and publish in some crap journal. Shame!

FBXW7 regulates DISC1 stability via the ubiquitin-proteasome system. Yalla, et al. Mol Psych 2018,23:1278-1286.
This Pfizer (and academic collaborator) paper shows strong, capable science. DISC1 is an important protein and it is degraded by a specific E3 ligase, FBXW7. Unfortunately, FBXW7 has other important substrates. The authors think they can make an inhibitor that only inhibits the FBXW7-DISC1 interaction but I am very skeptical of that. When do we see that in medicine? Anyone? Anyway, as far as target discovery from immunoprecipitation all the way to crystallography, Yalla et al do a tremendous job here.

Two Phase 3 Trials of Bapineuzumab in Mild-to-Moderate Alzheimer’s Disease. Salloway, et al. NEJM 2014;370:322-33.
Nothing to see here. Just another important history lesson in drug development.


Biopharma & Investing
A mega-price increase from a small company I had never heard of before: Aytu, who increased the price of their Ambien-containing nasal spray. This is actually a neat product, as some people have difficulty swallowing pills and it makes sense that a non-pill Ambien by the bedside may be easier to use. I once tried to buy a company (for $0 EV) called Transcept who made a ODT version of Ambien. That drug is now generic. If I worked at an HMO, I’d mandate people take that drug instead of the nasal spray. So, some price increases don’t work (or shouldn’t work). People who are on and are comfortable on this drug, however, are unlikely to be forced to switch. Maybe a higher copay (maybe much higher).

Beigene and Alnylam have similar valuations but extremely dissimilar prospects. Beigene is late-to-market in China for PD1 and extremely late to a crowded market in the US where they “share” economics with CELG. Their other drugs don’t target large markets. Alnylam has revolutionary technology which has proven successful in many clinical settings, with at least one drug that will sell well over $1 billion.

I’m starting to get worried about Bluebird. Wiping out your bone marrow and living in a hospital for 6 months may not be the cure for what ails you in the shadow of gene therapy for some illnesses and traditional modalities for others (sickle cell). But, BCMA!, you might say? Well, lots of companies have BCMA CART. The MM market is starting to worry me, too. We have lots of great drugs and we haven’t seen commercial success for CART yet. I’m starting to wonder about the upside here.

Some people want more from me on the subject of investing. I write this blog mostly for my teammates around the world who can study my notes and help my companies grow. I’m an unemployed passive investor, but if my philosophies and notes can be of use to someone, great. It’s free. I doubt I’ll give any structured theory of investing despite interest in a book on the subject. The grand unified theory for investing is still unclear to this observer, but I’ll share some explorations as they occur. I will probably write extensively on quantitative investing, value investing and other topics as time marches on.

One of my favorite questions in investing is how do you reconcile taxes in long-term market ‘expectations’? I, of course, believe that the expected median return for an individual global equity is actually negative. But if you are in the polyanna crowd, and you think for some insane reason that future stock performance will be 5% pa or something like that, how do you reconcile having to pay ~25% taxes (long-term rate) in the US? Does that make a 4% return a 3% return? How do you account for the asymmetry? And what about inflation, what is that really? In a world where the “price of goods and services” are irrelevant to a millionaire (any reasonable investor), shouldn’t the price of asset classes be your new inflation? After all, I’m not so worried about a tank of gas and a carton of milk. The prices of a Hamptons house and a La Ferrari are not in the current CPI basket, but your frame of reference is crucial to understanding inflation, in my opinion.

Anyway, if you believe, for whatever reason, that US stock markets going forward, measured by the S&P 500 index (implicit bias here, too), will average 5% per annum, what are you really getting? Well, you have to pay the 25% taxes, no matter what. I’m being generous as there are all kinds of hidden taxes, such as consumption tax, legal and accounting costs (which are, in essence, taxes). So that’s 3.75% net, but net of 2% inflation (whatever that is), you’re at 1.75% real returns. That’s including your massively foolish implicit bet that large-cap United States stocks have their best days ahead, as compared to say, China, India or any other country. You’d have to buy the Russell to avoid the large-cap bias, and perhaps hedge with international MNCs to avoid the US bias. If you could construct a basket of diverse market cap stocks, with their % of business in the US at perhaps 20%, you’d have a truly equity-like instrument. I think your performance net of inflation and taxes would be negative or zero. You might ask how this “system” could do anything but fall apart, in the long run. I’m not a perma-bear or anything like that. First, I don’t think expected return on equities is massively negative. Next, I think a large part of our financial system is constructed on a strange and amorphous foundation that still holds surprises for us. The stock market is ‘everything’ to so many, but real estate, private equity and other fields dwarf equities. Events in those markets impinge on stock performance such that sometimes its a good idea to pay $750 billion for $6 billion in annual (but growing!) cash flow and sometimes it isn’t. I’ll have more to say next time.

Papers I’ve Read
A Phase 3 Trial of Semagacestat for Treatment of Alzheimer’s Disease. Doody et al. NEJM 2013 369;4:341-350.
This is maybe the third time I’ve read this paper from 5 years ago. It’s rare in medicine to get a hypothesis so wrong that the drug does a statistically significantly WORSE job than placebo. This gamma-secretase “inhibitor” worsens cognition and functioning. Some believe it is in fact, not a gamma-secretase inhibitor, but I don’t agree. Peripheral reduction of the putative causative agent of Alzheimer’s, amyloid-beta, was seen, but CSF (no mention of cortical) amyloid-beta was not. Brain disease is region specific (paracrine) and that makes treatment quite difficult. For instance, hippocampal amyloid-beta may be harder to target than perhaps more vascularized areas of the brain. So what explains -9 ADL for placebo and -13 for drug, a palpably worse effect? Two possibilities come to mind.
First, this drug is inhibiting some enzyme that is causing the effect seen. Whether that target is gamma-secretase or not is an entirely different question. If it is gamma secretase, two more sub-questions result. 1) Does regiospecific inhibition explain this phenomenon? We have APP for a reason. It is possible APP aids cognition or synpatic function or something in one cortical area and is problematic when it aggregates in another (hippocampus, amygdala). Oxytocin, serotonin and other neurotransmitters work this way. 2) The second major question is this drug is inhibiting gamma-secretase but that is not the primary causal effect. Many enzymes like GSAP are in this cascade and enzyme conformation often is a signal onto itself for feedback purposes. Stopping gamma-secretase, which ordinarly processes (cleaves) a precursor protein (a common theme in peptide signal biology, see endothelin, angiotensin), may prevent a key feedback signal telling some gene to stop making APP, resulting in paradoxically greater APP. We see reductions in AB, so one is tempted to reject this hypothesis, but AB alone may not be the whole story.
If semagacestat’s target is not gamma-secretase, what enzyme is it, and how could it serendipitously have such a profound impact on cognition? This seems highly unlikely, and we should use this opportunity to probe semagacestat further to understand AD biology. We see immune changes with human dosing, raising the possibility that AD results from immune aging, a hypothesis that was once also speculated for cancer. With no CSF AB or PET changes, one still has to question target engagement for sema. The dosing of 100mg vs 140mg is terribly awkward and hardly seen in medicine. That we see an increase in AB40 and AB42 reduction at 140mg is somewhat puzzling. Why not 200mg? What is DLT here and where is it coming from? Everyone seems to be pointing the finger at NOTCH inhibition but would that really explain increased dementia? If so, why not reverse this process? How about some CSF PK data?
Anyway, this one is an important mystery for current, future and prospective drug hunters to look back on and learn from. A pharmacological mystery.

Phase 3 Trials of Solanezumab for Mild-to-Moderate Alzheimer’s Disease. Doody, et al. NEJM 2014 370;4:311-321.
A lot of observers felt Lilly could have filed and received approval for sola on these barely-missed Phase IIIs. Certainly they stoke the idea that beta-amyloid intervention in AD should begin as early as possible and tantalize potential benefit with predictive diagnostics. That EXPEDITION 2 wasn’t repowered for only mild disease is unfortunate, they probably would have met a primary endpoint. Then, EXPEDITION 3 failed. So, just remember that subgroups are still subgroups and even with an a priori mechanism of action, there is a bit of luck involved in these trials, and trying to squeeze out a really small treatment effect in a new trial powered for that small effect is likely to backfire. Why develop a drug that is, at best, a modest therapy? The lack of binding fibrillar AB probably did this one in. A prodromal study is ongoing, I believe.

Some people are interested in how sentencing works. Given that almost no one is a criminal defense attorney (a very tough job!), allow me to explain to the uninformed. In federal prison, there is no parole. “Good time” is roughly 15% of one’s sentence, assuming serious no violations (so far so good, on my end). However, the 15% is overstated, and actually works out to 13.8% or something like this. Some speculate that the entire 15% will be restored in a soon-to-come criminal justice reform. While I won’t hold my breath, you can look up and calculate the exact number of DAYS you would get on an 84 month sentence by statute. My attorneys and sentence consultant have done this, it’s around 12 months. As you may know, I was sentenced to 84 months, and as of two days ago, I have been in prison for 10 months, meaning I have 74 months to go. When you include “good time”, I would have 62 months left. We’ve only gotten started on calculating, however. Prisoners like me are able to do 10% of their sentence as “home confinement”, which would be 8.4 months. This option is not available to everyone, but for nonviolent crimes, it is available. It used to be 5% until very recently. Next, there is a program available to certain prisoners that reduces a sentence by 12 months. Finally, any half-way house time would overlap with home confinement time, but if greater than that time, would count. For instance, if halfway house of 12 months were assigned to a prisoner who had 8.4 months of home confinement time, that prisoner would simply get halfway house/home confinement of 12 months. So, 84 – 10 – 12 – 12 – 12 = 36. Of course, the final 12 could be as little as 8, and one of the 12s could be anywhere from 11.0 to 12.6. My lawyers and I are confident in those numbers, but the full range best case/worst case would be 35 to 40 months. So, I project I’m 37 months away from home at this time. I also have an appeal pending, don’t sleep on that 🙂 Anyone playing along at home is free to do their own calculations and comment on the site!

There’s a guy here who doesn’t know any Beatles songs. I think there are a few guys here. He wanted to know their most famous song. I said: “Yesterday, Hey Jude, Lucy in the Sky With Diamonds, err… Imagine? Yellow Submarine?”. Drew blanks. Did I miss one?

I think the left needs to talk about unity instead of resistance. I’d be willing to apologize to Lauren Duca for nagging and teasing her, apologize to Lena Dunham for offering to afford her private plane trip to Canada, and others. The right needs to reach across and stop the flame war, as fun as it is. People like Hannity, Carlson, Dinesh, Milo, any standard bearer for Republicans, should begin this process. If the left won’t agree to “lay down arms” and focus on strengthening our country instead of dividing us further, then their party will dwindle into irrelevance and implode in hatred (has it already happened?) But we shouldn’t follow that lead. Let’s find common ground and cease the incessant and overwrought narrative that everything left-of-center is malignant and everything right-of-center is righteous. My reasoning for this change of pace arises from witnessing the miserable sorrow of various pundits and commentators. Losing stinks, but cheer up. We can get through this together. We lose, too. Being happy is more important than having your life subsumed by complaining. You can be happy with Trump. I was happy with Obama. I was happy with Bush. I’m always happy because there are more important things than driving yourself (and others) crazy with politics. Some of us like politics, and are passionate about it, and that’s fine, too. But we can use a different, less inflammatory and flamboyant language to convey what we’re thinking. Sometimes the understated is far more effective than bombast.


There are a lot of tau-focused drugs in the clinic: antibodies, antisense. Which will read out first? Hopefully better luck than amyloid. Probably still too late in the disease process to work, but who knows?

Zogenix has themselves a great drug. I wonder how it works. Maybe just 2B antagonism? Anyone know?

Let’s continue with our R&D productivity analysis. Last time we determined Pfizer would have been better off never investing in R&D, and instead contributing their R&D expense to a hypothetical investment fund earning 5% per year. How about Merck?

Organic Merck R&D: Januvia/Janumet, Fosamax, Zocor, Mevacor, Singulair
Schering-Plough/Organon/Centocor/Johnson & Johnson: Zetia, Vytorin, Remicade, Simponi, Nuvaring, Claritin, Clarinex, Peg-Intron, Bridion, Temodar

This is a joke. The easiest way to lower drug costs is to allow interchangable biosimilars. Old, off-patent biologics are our biggest drug cost. Not mentioned here. The part that really irks me is the authors’ foolish CPI statistics. Yes, drug costs have outpaced inflation. Why, is the question? Why are consumers demanding these goods so much that their prices are rising? Its not a producer-only phenomenon. It has happened since the 1960s. We care about health. Companies are producing great innovations. We have more disposable income than ever. None of this is bad. What perverse insanity this writing is. Not to mention 90% of medical costs come from two letters and one punctuation mark: Dr.

Flatland by Edwin Abbott – A Modern Vantage Point
Flatland, though published in 1884, still has a voice that speaks to us today. A satire with a mathematical theme, Abbott not only indicts the backward Victorian-aristocrat thinking of his time but also wisely ruminates on higher dimensions. While Abbott foreshadowed the nearby Einstein (to a very small extent), he’d still be very happy to hear about Minkowski spaces and other manifolds where today’s minds contort themselves to understand higher spatial dimensions and fail. “We have no evidence to support the existence of a fourth spatial dimension, and if they do exist, they exist in a compressed and unobservable state”, a modern thinker might say. Not that Abbott was the first person to contemplate “4D” (Kant had him by a mile), but his narrative form is enchanting and illuminative for the simpler, 80-page readers among us.

What was Abbott saying from a psychosocial perspective? His perspective on heirarchy is timeless. Man’s attempt to find order in the world in relation to other men is futile and forgive me, circular. The sorrowful denizens of Flatland reasonably assign rank by the number of sides their person exhibits. The larger the number of sides, the more they approach the perfection ideal (that of a circle) and are accorded status as such. In today’s world, non-capitalist institutions such as politicians, government employees and the media resemble Flatlanders. Without the laissez-faires simplicity of financial order, the non-capitalists struggle to find order, and therefore, meaning. Capitalists have their own problems with meaning, which is an essay for another day. So, non-capitalists are Flatlanders, searching for a pecking order consisting mostly of who can make laws governing the capitalists, interpret and execute laws governing the capitalists, write stories about the capitalists, and sometimes simply and smugly, judge the capitalists. It’s good to govern (explicity in government and implicitly in the media) those you cannot compete with. This psychogical reordering is comfortable, like the pentagon who outranks the isosceles.

In Flatland, one irony is that large-sided polygons are so circle-like, but can never reach circlehood because they’re actually going backwards in the number of sides required: one. If anything, the lowly women, who are but “two-sided” (and often invisible) are closer to perfection than the 500-sided elder “circle”. So, too, it is with the non-capitalist group I described. What could be more frustrating right now than to be a lifelong politician/”civil servant”? To arrive in 2018 and realize you’ve accomplished nothing: President Trump just decided to become President and you are just some 200-sided shape trying to be 210-sided. The usurping of the aristocracy and the idiocy that created it in the first place is the point of Flatland. We don’t have an aristocracy in America, but we do have a strange edifice resembling some aristocratic properties. The government and media thrives on self-importance. Nothing makes journalists I confront angrier than when I tell them their stories don’t matter. No one reads them, no one believes them. You can call me “the most hated man in America”, but the reality is people cheer me and shake my hand everyday. I’ve gotten hundreds, maybe thousands of fan mail and two pieces of hate mail. Two! I’ve been in federal prison for ten months and have been treated like a hero for confronting media and government. If I’m hated, I’d like to see what loved looks like. Is that what Elizabeth Warren is? Nothing makes politicians/government officials angrier than when I make fun of them, often to their face. Don’t I know who they are? That they could put me in jail!?

The facade of the aristocracy’s power is what Flatland exposes. The facade is both the frustrated actions the edifice takes to self-perpetuate (laws, journalist output, the miasma of South Parkian smug filling our lungs) and its precious self-delusion, which must also not be shattered. Letting bubble-dwellers enjoy their setting is a reasonable way to handle their existence. Unfortunately, natural entropy occurs and the popping of safe spaces reminds the self-appointed enlightened that the path they chose is dim and foggy. The shape with the fewest sides, indeed, has the sharpest angles.

The 13th is my favorite day of the month, as I was remanded on the 13th and it’s easy to count the months. I have about 3 years left exactly. That I’ll spend 5% of my life in isolated study isn’t pleasant but books like Frankel’s “Man’s Search For Meaning” puts things into perspective! Everyone said the biggest downside to jail is boredom. I am not bored… very, very far from it.

–Does anyone think there is room for a lowish-priced antidepressant with a new MOA (not TRD)? I guess ALKS does. I gotta look at the data again but I really didn’t think that drug worked. I guess it’s true what they say, run 4 depression Phase IIIs to get two positive ones. Even JNJ’s data was underwhelming. GP/internist drugs are so scary now after so many flops, but look at Eliquis, doing amazingly well. So is 90s pharma over or not?

Some drugs have very low bioavailability (10-20%) and pose a potential risk if blood levels are variable. Protein binding is an important consideration in contemplating drug availability in conjunction with bioavailability.
gene amplification. in an oncology context, a copy number change, often induced by selective/evolutionary pressure
splice variants. the product of alternative splicing (very important concept).
prometaphase. the phase in mitosis before metaphase where kinetochores form.
metaphase. the phase in mitosis before anaphase where chromosomes align prior to separation
cytokinesis. when the cytoplasm of a single cell divides into two.
monopolar spindles. a spindle defect.
kinetochore. a protein that forms the attachment point for the spindle to separate sister chromatids.
chromatid. the copy of a chromosome attached to its template by a centromere.
apraxia. the inability to complete a fine motor task.
GPCR. G-protein coupled receptor. 7-transmembrane family of receptors coupled to a G-protein. Very common pharmacological targets.

I hate correcting the media. Some Vanity Fair reporter Emma Stefansky apparently said that my Wu-Tang album was no longer ‘mine’. That’s interesting since I pay for it to be stored and insured every month. Maybe someone can reach out to her and ask her who has it? Because I don’t know, I think I do. Maybe I’m wrong? Let me know.
The same thing applies to my finances. People know about 10% of the story. I’m wealther than I ever have been. Liquidity has always been a struggle for me. I don’t think I’ve ever been really liquid, basically ever. That’s just how it works with serial entrepreneurs who put everything they have into their companies. Elon Musk once said he couldn’t pay his rent. I think mere mortals don’t understand the concept of giving all you’ve got.
I’m sitting pretty though, as the IRS owes me a $4 million refund, I’m hopeful that the insane $7 million judgment gets reversed on appeal (which I’ve already paid most of), and I have about $22 million in uncashed options from my first company that I should probably cash in. It’s been difficult to do basic things like that since I was remanded for “hairjokegate” 2017. I guess I gotta find a notary here, they supposedly have one in the prison, but I’ve only been here for two months. Anyway, my private holdings are growing more valuable by the day, so I find it funny reading all the misinformed stuff about me.
One person told me “eh, don’t correct aynone, it will be even funnier when you buy a sports team and people will say ‘what a comeback'”. But, there’s nothing to “come back” from. Jail is adult time out. I haven’t learned anything profound from this experience, other than doing what most prisoners do, which is to stew and grow more resentful of our overreaching and corrupt law enforcement. I’m innocent and was narrowly convicted with the assistance of witness coercion, the government obtaining illegal evidence and all kinds of other government tricks. They certainly prosecute the person, not the crime. Lucky Luciano, Al Capone, you name it. A bad guy is a bad guy, doesn’t matter what they did. They’re trying to do it to our President as we speak. What law did he violate, so that we can get vengence for the political policies we don’t like? Shame on the FBI–it should be shut down. [End Count of Monte Crisco rant.]

Is Drake’s new album any good?

I’d like to see more responses in comments!!!!


Acadia. I still don’t think this drug will ever sell too much. There are a few D2 sparing 5-HT2a antagonists (nothing as pure as pimavanserin, given), but the company’s spending is a bit insane. The drug is probably great for PDP given the levodopa interference at the dopamine receptor, but what good is the drug for the other illnesses when you can use Risperdal, Abilify, Seroquel, etc. Re spending, I understand that one needs to invest in a brand, and it will stop at some point, but this is quite dramatic cash use. I am skeptical of the intellectual property of pima, so I expect a generic sooner than others.

Continuing our Pfizer (Merck next) R&D productivity analysis, what is fascinating is almost all of Pfizer’s drugs were discovered by other companies. I suppose it is not too surprising given the mega-mergers that have occured. Still, the idea that Pfizer has only created 11 drugs in the last 30 years despite spending >$100 billion on R&D fascinates me.

I assumed net margins on pharmaceutical products are 50% (well above what they really are but around what they are on a steady-state well-managed level). I assumed 50% of R&D is spent on discovering or running clinical trials for in-house projects (as opposed to clinical trials for acquired products). At a 3% discount rate, PFE made 32B for shareholders from 1991 to 2017 (16 years) investing in R&D. All of the profit was from 1992 to 2006, indicating very roductive R&D in the 1990s, creating monsters like Norvasc, Viagra and Zoloft. Net income of this “inHouseR&DOnlyCo” reached as much as $2 billion in some years. Net income turned negative afterwards, ranging from breakeven to negative 1 billion per annum since 2006.

If, instead of doing R&D, Pfizer invested the R&D cost (50% of reported cost) in a fund returning 5% after-tax, it would have generated 124B in value as opposed to the 32B NPV. I have never seen an analysis like this done (it has taken me the better part of 3 days).

I’ve been having a recurring dream about being able to go back in time and see the future and live the past simultaneously. I’m working at a hedge fund and I somehow know the future years in advance. I know that Facebook will get started in 2004. I know that Google is a great buy at or before the IPO. I know what drugs will work and what won’t (although I know that today). I knew the market will crash in 2000-2002 and recover in 2003. I guess this is what insider traders feels like?
