About Lerociclib
Lerociclib is a differentiated oral CDK4/6 inhibitor with potential use in combination with other targeted therapies in certain types of cancer.

At the San Antonio Breast Cancer Symposium (SABCS) in December 2019, G1 reported preliminary Phase 1/2 data on the differentiated safety and tolerability profile of lerociclib, along with preliminary efficacy findings that were consistent with other CDK4/6 inhibitors used in combination with fulvestrant.

Lerociclib is currently being evaluated in two Phase 1/2 clinical trials: a trial in combination with fulvestrant for patients with ER+, HER2- breast cancer (NCT02983071) and in combination with osimertinib in epidermal growth factor receptor mutated (EGFRm) non-small cell lung cancer (NCT03455829).

G1 entered into separate, exclusive agreements with EQRx (rights for U.S., Europe, Japan, and all markets outside Asia-Pacific) and Genor (rights for Asia-Pacific, excluding Japan) for the development and commercialization of lerociclib in all indications. EQRx and Genor are responsible for all costs related to the development and commercialization of lerociclib in their respective territories.
