Notable Last Week
CohBar announces share and warrants offering (dilution) @ $1.22 / share to raise $15 million in cash. This is bad news for the shareholder of the mitochondrial peptide therapeutics company co-founded by Nir Barzilai. The stock was down 33% for the week.
LyGenesis publishes successful results in progress on growing ectopic livers in lymph nodes of pigs. The Juvenescence-backed private company is moving forward to trials in humans with terminal livers disease. Now only if Juvenescence would hurry up with that IPO…
Amgen (AMGN) replaces Pfizer (PFE) in the Dow Jones Index. The Dow Jones Index is meant to be a broad representation of the American economy. Replacing Pfizer (traditional pharma) with a the biggest biotechnology company (Amgen) speaks to the revolution already underway. Ditto with SalesForce replacing ExxonMobil.
Elon Musk’s Neuralink unveils a working brain implant in pigs. Although not considered traditional longevity biotech, developments in brain machine interfaces will further transhumanist goals and potentially help treat various brain and neuromuscular injuries or disorders. I’ve long wondered whether the problem of longevity could be sidestepped entirely with mind uploading or brain preservation.
Organovo (ONVO) rebounds. As I mentioned in my newsletter last week, the 20-1 reverse split in the stock had battered the price long enough. The stock then bounced 18% on Tuesday — unfortunately two days earlier than my “perfect” entry. I am not interested in buying and holding this stock unless there is a compelling thesis that could override the ominous shadow of their 20-1 split and monster drawdown from all time highs.
Longevity stocks mostly down this week. XBI Biotech sector ETF down 2.4% on the week. In contrast the SP500 was up 3.2%. Perhaps the enthusiasm for biotech is dying down now that the Covid-19 vaccine winners landscape is tightening up. Less uncertainty to speculate on now.
7th Aging Research and Drug Discovery (ARDD) 2020 is taking place online from September 1 - 4, 2020. The list features an astounding number of titans from academia and industry: (Aubrey de Grey, David Sinclair, Nir Barzilai, Alex Zhavoronkov, Brian Kennedy, Judith Campisi, Kai-Fu Lee, Steve Horvath, Jim Mellon, and many many more). It is FREE. Highly recommend days 1 and 4 of the conference.
Mesoblast to release interim data Ph. III trial for Covid-19 ARDS treatment with remestemcel-L early September. Here are the trial details. A positive result would be welcome news for reducing the severity of the pandemic.

Hot or Not: A breakdown of the best longevity stocks on LongevityMarketcap.com
LongevityMarketcap.com is a website that tracks all the publicly-traded longevity biotechnology stocks. Currently there are 16 stocks listed.
I only have 3 longevity stocks in my portfolio: Mesoblast (MESO), Unity Biotechnology (UBX), AgeX Therapeutics (AGE).
Why am I not invested in all of 16 stocks listed on LongevityMarketcap.com? After all, I do preach the importance of diversification in biotech, which is a numbers game.
Well to be fair not all of the stocks are pure longevity plays. Some are also European listed (which can be tricky for some brokerages).
Let’s do a breakdown of all 16 longevity stocks, and why they are in or out of my portfolio. We’ll start from the top (by marketcap):
1. Grifols S.A ($15.63 B)
Grifols (GRFS) is a Spanish blood protein and chemicals company and the largest company on LongevityMarketcap by far. It’s more of a “blue chip” blood biochemicals company than a pure anti-aging speculative biotech.
Has a 45% stake in the notable longevity startup, Alkahest (they do young blood / old blood plasma factors — chronokines)
Also recently published results of their AMBAR trial that used albumin replacement to treat Alzheimer’s disease. A combination of albumin replacement and a proprietary immunoglobin slowed the progression of Alzheimer’s disease over 14 months. Not a huge result but it is notable. An interesting background read on AMBAR can be found on Josh Mitteldorf’s blog.
Shares are dual listed (depository) and available on the Nasdaq.
Grifols is a big company and their anti-aging projects (Alkahest / Alzheimer disease treatment) only represents a small percentage of the company. If you invest, you are mostly investing in a biologics supply manufacturer.
Verdict: If I could only invest in Alkahest, I would. Currently, I think investing in Grifols is too dilutive with its non-longevity business.
2. Denali Therapeutics ($3.38 B)
Denali Therapeutics (DNLI) is a developer of drugs that targets neurodegenerative disease. According to Gregory Bailey (CEO of Juvenescence) in an interview on the Simple Biotech Podcast, neurodegeneration will be the major gating function on the limits of radical life extension.
Denali’s main advantage is their blood-brain transport technology. Most small molecule, antibodies, and enzymes cannot easily cross the blood-brain barrier to maintain high concentrations in the brain. Denali uses a technology platform involving receptor-mediated transcytosis to move large macromolecules across the blood-brain barrier. Basically, they use molecules to bind to the endothelial cells of the blood-brain barrier, which then get actively transported into the brain.
Biotech behemoth Biogen ($45 B marketcap) announced on August 6th that they would invest in Denali to co-develop their LRRK2 (leucine-rich repeat kinase) pipeline for Parkinson’s disease. The deal included $560 million dollars upfront.
A lot of high profile drug failures in this space already. Failure rate for Alzheimer drugs is 99%.
For some psychological reason I find it hard to get excited about fighting aging in the brain — even though it may be the fundamental dealbreaker for life extension. Don’t get me wrong — I love my brain. But perhaps neuro-diseases are not as sexy as reversing cellular aging, which seems more fundamental.
Verdict: Biogen has made a big bet on this company. Might be worth a bet. Though, I expect failure to be the most likely outcome and will size appropriately.
3. Mesoblast ($2.3 B)
This Australian stem cell therapy company specializes in using allogenic mesenchymal stem cells and mesenchymal progenitor cells treat a variety of diseases, mostly related to inflammation or acute damage.
Already has stem cell therapy products approved for use in Europe and Japan.
Ryoncil received a favourable 9-1 vote from the FDA Oncology committee for use in pediatric steroid-refractive Graft vs Host Disease. It is likely the FDA will approve Ryoncil on September 30th.
Although the company does not market itself as a longevity company, their stem cell therapy products all tend to target inflammation and or enable regeneration (Revascor, in the heart). They currently have a Phase III trial of a regenerative therapy targeting disc degeneration that causes age-related chronic low back pain.
The usual suspects with cell therapies: manufacturing and administration is trickier.
Verdict: I’m already invested in Mesoblast. I think they are developing some great rejuvenation technology that could be translated to more broad areas of aging (inflammaging, regeneration) in the future.
4. ALX Oncology ($1.49 B)
ALX Oncology (ALXO) is a Longevity Fund backed immuno-oncology company that focuses on inhibiting the CD47 cell surface protein that helps cancer cells evade the immune system.
The whole field of immuno-oncology is very hot in biotech right now.
Age-related CD47 overexpression may be linked with reduced vascular function. So possible translational work for anti-aging.
Fresh off its IPO in July, the stock still has too much hype for me to decide on investing.
This looks like a promising immuno-oncology play that could also target aging in the future. Unfortunately, I don’t know enough about this stock to warrant investing during the post-IPO hype phase. If it (ever) drops to 15$ / share I would consider it.
5. Alector ($1.02 B)
Alector (ALEC) is a neurodegenerative drug developer that has a unique immunotherapy approach. They aim to functionally repair genetic mutations that impair the immune system of the brain.
Novel twist on neurodegenerative disease and immunology
Perhaps technology can translate to immuno-senescence as a whole
Strong $500+ million in cash on balance sheet. Partnerships with big pharma
High failure rates for Alzheimer’s disease drugs (99%)
Verdict: Same as Denali Therapeutics and all other large neurodegeneration biotechs. Extremely high failure rates so plan accordingly.
6. Frequency Therapeutics ($650 M)
Don’t be fooled. Frequency Therapeutics (FREQ) sounds like a company that is focussed primarily on restoring hearing loss. Indeed, that’s the main pipeline.
But actually the company has an ambitious plan to extend its small molecule targeted regenerative medicine approach to all parts of the body. Their drugs aim to stimulate inactive progenitor cells in target organs to regenerate functional tissues. They are currently conducting Phase II trials for sensorineural hearing loss.
Progenitor Cell Activation (PCA) has potential broad regenerative ability.
Sensorineural hearing loss is a huge market, especially in aging population
Has the first clinical data to ever demonstrate improvements in hearing
FDA Fast Track designation.
Nothing that I can tell so far.
Verdict: I am a fan. As a guy who played drums back in the day and suffers from some hearing loss, I feel like this is personal.
7. Athersys ($430 M)
Athersys (ATHX) is a stem cell therapy company much like Mesoblast. However instead of using mesenchymal stem cells (MSC) they develop a proprietary Multipotent Adult Progenitor Cell (MPAC) derived from bone marrow. They currently have clinical trials investigating treatment for ischemic stroke and acute respiratory distress syndrome (ARDS, for Covid-19).
MPACs are claimed to have superior cell differentiation ability compared to MSCs.
Broad regenerative / anti-inflammation potential
“Off the shelf” product
Similar to Mesoblast and other cell therapies. Manufacturing is trickier (compared to small molecule). Harder to target intracellular causes of aging.
Verdict: This company has many similarities with Mesoblast so it may also warrant an investment out of principal. I will keep my eye on it.
8. Unity Biotechnology ( $160 M)
Unity Biotechnology (UBX) develops drugs that target senescent cells — cells that stop dividing and, instead of dying, secrete harmful factors that are implicated in causing aging.
The only publicly-traded company that targets senescent cells — a major hallmark of aging.
Strong backing from The Longevity Fund, Founders Fund (Peter Thiel), Bezos Expeditions, ARCH Venture Partners, etc.
Recent stock price implosion (-70%) from failed osteoarthritis trial (I’ve written extensively on this, see #005, #006). Perhaps the valuation is “cheap” now.
Failed trial potentially casts doubt on senolytics and senescent cell hypothesis.
Verdict: I’m already invested. It’s the only publicly-listed senolytics company and at these prices I might be tempted to increase my bet.
9. Lineage Cell Therapeutics ($137 M)
Lineage Cell Therapeutics (LCTX), formerly BioTime, is a cell therapy company that uses pluripotent cells to treat age-related degenerative diseases and other serious conditions. They currently have Phase II trials targeting Dry Age-related Macular Degeneration and also Spinal Cord Injury. A Phase I trial of a cancer vaccine that stimulates the immune system against telomerase is in the process of enrolment.
Broad regenerative medicine mission
Mike West (OG of stem cell therapy and now at AgeX Therapeutics) was CEO of the company.
Stock price is down 96% from its highs. That’s usually not a good sign.
Cellular therapies can be tricky to manufacture. Also has limitations on what they can target due to nature of interaction.
Verdict: A massive 96% drawdown is a huge red flag to me. I am staying away until I can do better due diligence.
10. Gensight Biologics (94 €M)
Gensight Biologics (SIGHT.PA) is one of the weirdest companies on this list. Weird is good.
They specialize in using gene therapy to target rare inherited retinal diseases such as Leber Hereditary Optic Neuropathy (LHON).
LHON results from a mutation affecting the ND4 mitochondrial gene. Their approach uses adeno-associated virus vectors to express the ND4 gene in the nucleus. Mitochondrial Targeted Sequence (MTS) shuttles ND4 messenger RNA from the nucleus to the membrane of the mitochondrion to synthesize the missing protein.
Really unique gene therapy approach to retinal diseases
MTS technique has potential to solve other conditions related to mitochondrial mutations / dysfunctions that cause aging.
Verdict: I don’t know enough about rare disease trials or gene therapy. There is certainly less stigma associated with gene therapy now after Spark Therapeutics’ commercial success. More research needed.
11. resTORbio ($83 M)
resTORbio (TORC) is a small molecule drug company that develops rapalogs (i.e. rapamycin analogs) to treat age-related disease. Rapamycin is an immunosuppressant drug that also happens to increase the life expectancy of mice up to 60%. Currently the company is in Phase 2 trials of a combination rapalog + rapamycin to treat Parkinson’s disease.
Only publicly traded company targeting the mTOR pathway — one of the most popular pathways studied in aging.
Big failure of their respiratory disease trial at the end of 2019 caused the stock to drop 86%
In April 2020, resTORbio announced a merger with Adicet Bio, a CAR-T cell therapy company. The combined company will take on Adicet Bio’s name and the shareholders of Adicet Bio will own 75% of the new company. resTORbio shareholders announced a lawsuit against the board of directors.
Verdict: The high profile clinical trial failure, weird merger, and lawsuit are big enough red flags for me to stay away from this company. People in the longevity company had high hopes for this company.
12. Stealth BioTherapeutics ($76 M)
Stealth BioTherapeutics (MITO) is a company that develops drugs that target mitochondrial disorders, dysfunctions, and diseases. Their main pipeline revolves around Elamipetride, which is currently being tested in Phase III clinical trials for Barth Syndrome — a rare disease of multiple systems.
A pure longevity small molecule play that targets a central pillar of aging — mitochondrial dysfunction
Big Phase III trial failure of elamipetride to treat patients with primary mitochondrial myopathy (PMM) in Dec 2019.
Stock is down 93% from its highs.
Verdict: Reusing the same failed compound to treat an another mitochondrial dysfunction might be a little risky. I’m staying away from this one.
13. Organovo ($56 M)
Organovo (ONVO) is a 3D bioprinting company that makes tissues for research purposes and drug testing. They specialize in printing a variety of 3D tissues using human cells and biogel fillers to simulate real in vivo conditions versus 2D cellular plate cultures.
Not a therapeutics company. They sell a tool for research and drug testing.
Technology improvements coupled to advances in traditional 3D printing?
Included in ARK Invests “Genomics" Revolution” thematic ETF
20-1 reverse stock split in August 2020.
Share price is down 96% from all time highs
Verdict: Not a fan. The reverse split and massive drawdown aren’t enough to convince me to invest.
14. CohBar ($42 M)
CohBar (CWBR) is a company that develops therapeutics using mitochondrial peptides (short strings of amino acids). They currently are in Phase 1 clinical trials for treating NASH (a type of nonalcoholic fatty liver disease) and obesity.
Co-founded by heavyweights in longevity academia: Nir Barzilai and David Sinclair
Clearly focussed on a major hallmark of aging: Mitochondrial dysfunction.
CohBar announced a dilutive share sale below the market price in order to raise ~$15 in cash last week.
Verdict: The recent crash caused by the share sale might be a represent a good entry. No comment either way.
15. Biophytis (35,84 €M)
Biophytis (ALBS.PA) is a French company that is developing drugs inspired by medicinal plant metabolites to treat sarcopenia (age-related muscle loss). They are currently running a Phase II clinical trial.
Clearly marketed as a pure-play longevity therapeutics company
Unique hypothesis: Using stressed-plant metabolites as candidates to find drugs to treat conditions of aging. This xenohormesis idea is discussed in David Sinclair’s book Lifespan
No comment. Seems like a very small company. Extra risky.
16. AgeX Therapeutics ($33 M)
AgeX Therapeutics (AGE) is a pre-clinical company that is developing stem cell therapies and induced tissue regeneration in order to target aging and age-related diseases.
Founder, Mike West, is an OG in stem cell research
Latest earnings report showed signs of financial distress
Verdict: I’m already invested but technically speaking the stock chart looks pretty precarious. It’s a very small pre-clinical company so I am keeping my position size small.
Even though it is early days in the longevity industry (aka the future world’s biggest industry) there are still a good number of investible stocks. And more will be coming.
As the number of publicly-traded longevity stocks grows we will need some sort of Longevity Biotech ETF that would make owning a diversified portfolio of these companies less onerous.
This neurodegeneration therapeutics stock took a tumble at the end of July due to a report of logistical complications brought on by the pandemic during their phase II dementia trials.
Trials are expensive and delays or missed doses can cause issues with analyzing data after the fact. The stock is now down almost 50% since the report and has been slowly climbing up for the past two weeks. This seems like a potential bottom. I’m interested.
Frequency Therapeutics (FREQ)
I only seriously started considering this small molecule progenitor cell activator company this week after researching it for this newsletter.
The stock is down about 18% in a couple weeks with momentum indicators getting close to showing a reversal. If we reach a TD sequential 9 on Thursday I might buy at end of day.
Love your newsletter!
One thing worth mentioning IMO about AgeX is that AdG is CSO.
