CMG901 is currently in a Phase I clinical trial for the treatment of Claudin 18.2-positive solid tumors. Preliminary results from the Phase 1 trial indicated that CMG901 has a favorable safety and tolerability profile, and encouraging anti-tumor efficacy across the dose levels tested.

Financial Considerations

Under the terms of the agreement, KYM Biosciences, the joint venture established by Keymed and Lepu Biopharma, will receive an upfront payment of $63m on transaction closing and additional development and sales-related milestone payments of up to $1.1bn as well as tiered royalties up to low double-digits. The transaction is expected to close in the first half of 2023, subject to customary closing conditions and regulatory clearances.

This is not only a recognition of CMG901, a potential first-in-class Claudin 18.2 ADC, but also Keymed's internal discovery and development capabilities. The global scope of this agreement has the potential to benefit patients in China, and throughout the world."
