ImmuneAGE Pharma is the first platform company focused on immune system rejuvenation. They are targeting immune aging at the source — the hematopoietic stem cells (HSCs) of the bone marrow. The company’s lead program, IA101, is a non-toxic small molecule that rejuvenates aged HSCs and aged animal immune function (oral administration) better than any molecule previously published. The company is seeking funding to support the further optimization and preclinical development of the IA101 program. The company is willing to execute an IP-NFT.
Immune aging and chronic inflammation drives the major killers and age-related diseases: infectious disease (e.g., COVID), cardiovascular disease, neurodegeneration, metabolic syndrome, chronic inflammatory conditions and autoimmunity, and tumor immunosurveillance in oncology, etc. COVID has underscored the importance of immune aging — the factor most determinative of death and disability was biological age. Today, lung infection by other pathogens remains the 4th leading cause of death globally. Furthermore, tumors can exist and spread only when the immune system fails to control them. And yet, there has never been a systematic effort to find drugs that rejuvenate the immune system at the source: HSCs.
Harnessing the immune system is an extremely powerful approach in oncology — the immune-oncology (I/O) revolution, which yielded a Nobel Prize in 2018 — is the hottest area of biopharma today. These methods (checkpoint blockade, T and NK cell therapy, pro-inflammatory cytokines) tend to be “blunt instruments,” revving up the immune systems of patients whose immune systems have already failed (allowing cancer to emerge in the first place).
Despite this evidence for the efficacy of immunotherapy, there are few companies seeking to rejuvenate the entire immune system at the source: the bone marrow and hematopoietic stem cells. The hematopoietic stem cells (HSCs) of the bone marrow are the most powerful stem cells in the body (aside from the embryonic stem cells during development) — with the highest replicative capacity of any cell type (producing 200 billion red blood cells per day and 10 billion white blood cells). HSCs produce all the blood cells, and when rejuvenated in the lab, can extend the healthy lifespan of lab animals up to 30%.
ImmuneAGE’s lead program, IA101, is a non-toxic small molecule that rejuvenates aged HSCs and aged animal immune function (oral administration) better than any molecule previously published (to be published in Nature Aging later this year). A less potent natural product analog of IA101 has shown efficacy and safety in multiple human clinical trials, de-risking clinical development.
IA101 was discovered in scientific co-founder, Prof Nicola Vannini’s lab. Dr. Vannini has developed a unique assay for profiling metabolic function of HSCs and other immune cells. This platform enables the high throughput screening of compounds that reprogram immunometabolism. He has identified several molecules that enhance immune function, in vivo and ex vivo, and this platform is able to identify many more at scale. The Vannini lab has shown that metabolic reprogramming agents can enhance HSC function in vivo, as a first proof of concept for the platform. This compound is not drug-like, but Prof Vannini has since found other active scaffolds in vitro and in vivo, including an analog of our lead program, IA101 (Nature Aging, in revision).
Plan and IP roadmap
With proceeds from VitaDAO, ImmuneAGE will develop new IA101 analogs in order to strengthen their IP, enhance potency and drug-likeness, and identify the molecular target. With ImmuneAGE’s unique screening platform, they will be able to quickly iterate the new candidates to select a final pre-clinical candidate to move towards IND.
ImmuneAge will file intellectual property around the optimized IA101 derivatives discovered from the funding of this project.
Financing and cost breakdown
The current financing, future financing commitments, combined with potential funding from the VitaDAO community, would cover the following activities:
- HTS for HSC rejuvenator compounds with University collaboration - 200k
- Medical Chemistry to synthesize novel derivatives of IA101 - 250k
- Validation of top compounds in HSC transplant mouse models - 200k
- Target ID studies for IA101 and related molecules - 150k
The primary costs are with medicinal chemistry in collaboration with WuXi and medicinal chemist consulting budget.

Senior expert evaluation
This proposal has been evaluated by two scientists, a venture capitalist, and a business expert, obtaining an average score of 4/5.
- ImmuneAGE is the first LongBio company to focus exclusively on immune aging drug discovery
- The lead asset, IA101, already has proof of concept data in-vivo, outperforming all other HSC immune compounds in the literature.
- The lead asset is based on the same scaffold of a natural compound with a strong safety profile and significant median and maximum life extension data in mice
- Founder is a prominent founder and VC in the longevity space with >600M equity value in co-founded companies in the last 5 years. Team has >100+ years collective experience in drug development, immunology, venture capital, and pharma/biotech.
- Prestigious investor base at such an early stage.
- Immune rejuvenation is uncharted territory
- The company still needs to prioritize the clinical strategy in order to focus on the right indication
- The target of IA-101 is still unknown, although the company has plans to identify it
- Life extension in mice might not translate in humans, as any other candidate longevity intervention
- Early stage company, faces financing risk if market conditions weaken (although their pre-seed round was heavily oversubscribed and raised quickly in <1 month).
