ImStar Therapeutics is a private biotechnology company headquartered in Vancouver that is developing new approaches to treat patients with Amyotrophic Lateral Sclerosis (ALS), also known as Lou Gehrig's disease.

The company is developing compounds directed at a proprietary new therapeutic target for ALS discovered by co-founder Dr. Jean-Pierre Julien called TANA (i.e. TDP-43 Associated NF-kB Activation). The lead drug candidate, IMS-088, is a novel small molecule compound targeting the NF-kB activation pathway currently in preclinical development for ALS.

IMS-088 is the first in a series of novel compounds derived from withaferin A (WA), a natural withanolide isolated from the leaves of the winter cherry plant (withania somnifera).  In preclinical animal studies, WA showed promise but lacked suitable pharmacologic characteristics to be developed as a therapeutic drug.

Therapeutics targeting the TANA pathway could treat multiple neurodegenerative diseases expressing TDP-43 pathology such as ALS, Alzheimer's, Parkinson's and Dementia.

TAR DNA-binding protein 43 (TDP-43) was recently identified as a major disease-associated protein in ALS. Under normal conditions, TDP-43 regulates RNA and is predominantly localized in the nucleus. However, in ALS-affected neuronal cells the protein is misprocessed resulting in aggregation in the cytoplasm and a loss of motor function.

A recent discovery has shown that, in patients with ALS, TDP-43 unexpectedly associates with and activates nuclear factor-κB (NF-κB), an inflammation-regulating protein. This leads to exaggerated immune responses and motor neuron destruction. Inhibition of the pathway in an ALS disease model produced substantial improvements in disease and motor function illustrating this is an important new drug target.

Novel Withanolides

ImStar chemists have designed novel withanolides related to WA that have superior drug like properties. IMS-088 is the lead drug candidate in this series that is currently being developed for ALS. These compounds are covered by a new composition of matter patent filing.

TANA Inhibitors

ImStar is also developing various approaches to block TDP-43 activity and has identified novel single chain variable domain antibody fragments (scFv) that inhibit TDP-43 and block it's associated NF-kB activation. 

Joslin Diabetes Center is a foundation based in Boston, Massachusetts that was founded in 1898, and is the world's largest diabetes and clinical care organization.

Kairos Therapeutics has developed a proprietary next generation antibody-drug conjugate (ADC) platform based on novel toxin, linker and site-specific conjugation technology. Kairos has demonstrated superior pre-clinical in-vivo efficacy over T-DM1. Further pre-clinical studies demonstrate Kairos’ ADCs have superior tolerability and therapeutic index, compared to other leading platforms which may lead to greater clinical efficacy. Through key partnerships, Kairos is developing a novel therapeutic pipeline and is out-licensing its ADC platform to companies seeking access to state-of-the-art technology.  

Life Science Angels Inc was founded in 2004 and is based in Sunnyvale CA. The group makes early-stage equity investments in a wide range of life science companies. Life Science Angels invests primarily in California but is open to investing out of state provided a round is being syndicated with a local angel group. Life Science Angels does not rule out investing outside the USA but has yet to do so. The group invests as individuals and allocation sizes are therefore highly varied but are usually of about $2-$6, Life Science Angels usually invests in rounds seeking $3 million or less. The group is interested in syndicating rounds with other angel groups.

Life Science Nation (LSN) is the premier sourcing platform for market intelligence and prospect pipeline development in the life science arena. LSN enables life science professionals to generate a list of qualified global targets that are a fit for their company’s products, services, and fundraising efforts. The ability to generate these Global Target Lists (GTLs) makes life science professionals more effective and efficient. 

Lilly Asia Ventures is the venture capital arm of Eli Lilly that focuses on investments in the life sciences in Asia, particularly China. The firm was established in 2008 and is based in Shanghai, China. The firm is stage agnostic; investing in early, growth, and up to pre-IPO opportunities. The firm’s investment size is USD 5-20 million per company. The firm primarily invests in companies in China, but is open to companies across Asia-Pacific as long as there is some sort of China angle. The firm is actively seeking new investment opportunities.

Lilly Asia Ventures primarily focuses on therapeutics but is also interested in medical devices, diagnostics, animal health, and biotech other. The firm is most interested in products that will have a significant impact on medical care in China. For therapeutics, the firm seeks best-in-class or first-in-class products. The firm is opportunistic to the indication and the phase of development and will consider products in pre-clinical up to NDA. Historically, the firm invests in therapeutics for oncology, inflammatory diseases, and metabolic disorders.
