RESEARCH TRIANGLE PARK, NC and CAMBRIDGE, MA, USA I July 22, 2020 I G1 Therapeutics, Inc. (Nasdaq: GTHX), a clinical-stage oncology company, today announced a license agreement for lerociclib to EQRx™, a biopharmaceutical company focused on making innovative medicines at dramatically lower prices for the benefit of people and society. Under the terms of the agreement, EQRx gains exclusive rights for lerociclib in the U.S., Europe, Japan and all other global markets, excluding the Asia-Pacific region (except Japan). G1 will receive an upfront cash payment of $20 million and will be eligible to receive development and commercial milestone payments of up to $290 million, plus tiered royalties ranging from mid-single digits to mid-teens based on annual net sales of lerociclib.

“We are excited to partner with EQRx to further development of lerociclib, a differentiated oral CDK4/6 inhibitor designed to enable more effective combination treatment strategies,” said Mark Velleca, M.D., Ph.D., Chief Executive Officer of G1. “This is the third strategic collaboration we have executed this year. Collectively, these partnerships have advanced our goal to provide global access to our promising oncology therapies and extend our financial runway so that we can continue our efforts to bring novel treatments to patients with cancer.”

Discovered and developed by G1, lerociclib has demonstrated clinical proof-of-concept and a differentiated profile in a Phase 1/2 trial in patients with ER+, HER2- breast cancer. Earlier this year, G1 licensed development and commercialization rights in the Asia-Pacific region (excluding Japan) to Genor Biopharma.

About Lerociclib
Lerociclib is a differentiated oral CDK4/6 inhibitor being developed for use in combination with other targeted therapies in certain types of breast and lung cancer. Preliminary clinical data in estrogen receptor-positive, HER2-negative (ER+, HER2-) breast cancer have demonstrated proof-of-concept of the differentiated clinical profile of lerociclib versus currently marketed CDK4/6 inhibitors, with improved tolerability and less neutropenia. Neutropenia is one of the main toxicities associated with CDK4/6 inhibition. Current treatments require frequent blood testing for neutropenia. Less monitoring would mean fewer office visits and blood draws, improving the experience for patients and reducing the burden on physician offices and costs to the healthcare system.
