G1 Therapeutics and Deimos Biosciences Announce Global (Excluding Asia-Pacific) License Agreement for Lerociclib for Radioprotective Uses

- Jupiter Bioventures will Gain Exclusive Rights for the Clinical Development, Regulatory Submissions, and Commercialization of Lerociclib for Radioprotection in the US, Europe, Japan, and All Other Global Markets Excluding Asia-Pacific -

RESEARCH TRIANGLE PARK, N.C. and SAN FRANCISCO, May 22, 2024 (GLOBE NEWSWIRE) -- G1 Therapeutics, Inc. (Nasdaq: GTHX), a commercial-stage oncology company, and Deimos Biosciences, a portfolio company of Jupiter Bioventures, announced a global licensing agreement (excluding the Asia-Pacific region) for lerociclib for radioprotective uses. Lerociclib is a potent and selective inhibitor of cyclin-dependent kinases 4 and 6 (CDK4/6). Such inhibitors can increase the survival of animals exposed to radiation.

Jupiter Bioventures is a company creation engine that focuses on de-risking early-stage projects, partnering with the world’s leading biologists and physicians.

"Deimos Biosciences is an example of the diverse assets in the Jupiter portfolio with tremendous potential benefit,” said Nathaniel David, co-founder and Managing Director of Jupiter Bioventures. “We are thrilled to see this program advance and to be a part of developing a solution in an area of high unmet need."

Deimos Biosciences has the exclusive rights to develop, manufacture, and commercialize lerociclib for certain radioprotective uses in the US, Europe, Japan, and all other global markets, excluding the Asia-Pacific region, which G1 has already licensed to Genor Biopharma. In addition, Lerociclib was recently licensed globally (excluding the Asia-Pacific region) to Pepper Bio for all indications except for certain radioprotectant uses.

Under the terms of the agreement, G1 is expected to receive shares of Deimos Biosciences’ common stock representing 10% of Deimos Biosciences’ outstanding equity capitalization on a fully diluted basis, in addition to a 20% royalty on aggregate annual net sales of lerociclib.

"We are excited to partner with Deimos Biosciences on the development of lerociclib for radioprotective measures," said Jack Bailey, Chief Executive Officer of G1 Therapeutics. "This is an area of critical need where lerociclib may hold meaningful promise based on our previous work when G1 was being founded and we look forward to advancing its development for this important purpose."

About Lerociclib
Lerociclib is a differentiated oral CDK4/6 inhibitor based on its unique attributes, including its increased selectivity and potency for CDK 4 and CDK 6 and shorter half-life. Preliminary clinical data in hormone receptor-positive, HER2-negative (HR+, HER2-) breast cancer have demonstrated proof-of-concept of the differentiated clinical profile of continuously dosed lerociclib versus currently marketed CDK4/6 inhibitors, with improved tolerability and less neutropenia while maintaining robust clinical activity. Lerociclib has been licensed to Genor Biopharma in the Asia-Pacific region (excluding Japan) and is under National Medical Products Administration review in China for 1L and 2L HR+/HER2- breast cancer. Lerociclib was recently licensed globally (excluding the Asia-Pacific region) to Pepper Bio for all indications except for certain radioprotectant uses.
