What was measured

To assess the complete response (CR) + partial response (PR) rate (as defined by the 2015 MDS/MPN-IWG criteria) with cobimetinib treatment in CMML. This outcome measure will report the count of patients achieving complete response complete response (CR) or partial response (PR) while on the study.

Groups in this outcome

HMA Refractory

Patients treated with hypomethylating agent (HMA) refractory chronic myelomonocytic leukemia (CMML; 2022 WHO classification) with RAS pathway activation. Experimental: Treatment: All Patients Cobimetinib is taken on a 28-day cycle. Each dose consists of three 20 mg tablets (60 mg) and should be taken once daily for 21 consecutive days (Days 1 to 21-treatment period); followed by a 7-day break (Days 22 to 28-treatment break). Each subsequent cobimetinib treatment cycle should start after a 7-day treatment break has elapsed.

Newly Diagnosed

Patients with newly diagnosed chronic myelomonocytic leukemia (CMML; 2022 WHO classification) with RAS pathway activation. Experimental: Treatment: All Patients Cobimetinib is taken on a 28-day cycle. Each dose consists of three 20 mg tablets (60 mg) and should be taken once daily for 21 consecutive days (Days 1 to 21-treatment period); followed by a 7-day break (Days 22 to 28-treatment break). Each subsequent cobimetinib treatment cycle should start after a 7-day treatment break has elapsed.
