Lunresertib Camonsertib

Repare Therapeutics announces Fast Track Designation granted by the FDA for Lunresertib in combination with Camonsertib for the treatment of platinum-resistant ovarian cancer. Membrane-associated Tyrosine- and Threonine-specific cdc2-inhibitory kinase MYT1 (PKMYT1) is a regulator of CDK1 phosphorylation, and PKMYT1 is identified as synthetic lethal with cyclin E1 (CCNE1) amplification.
Lunresertib (RP-6306) is a first-in-class PKMYT1 inhibitor to enter clinical trial. Lunresertib is studied alone and in combination with Camonsertib in patients with advanced solid tumors. Camonsertib (RP-3500) is a potent and selective ATR inhibitor, that helps Lunresertib activate CDK1 and promotes premature mitosis. The combination is previously granted Fast Track Designation for the treatment of adult patients with CCNE1 amplified, or FBXW7 or PPP2R1A mutated endometrial cancer.
