Mantle Cell Lymphoma

A multicenter phase 1b/2 trial investigated the effect of venetoclax, lenalidomide, and rituximab (venetoclax-R2) in 59 patients with relapsed/refractory mantle cell lymphoma and found an overall response rate of 63%, median progression-free survival of 21 months, and median overall survival of 31 months (1). This trial was registered at www.ClinicalTrials.gov as #NCT03505944.

Mantle Cell Lymphoma

A Phase 1 study investigated the safety and tolerability of pelabresib in 44 patients with acute leukemia, high-risk myelodysplastic (MDS) syndrome, or MDS/myeloproliferative neoplasms and found that the maximum tolerated dose was 225 mg tablet QD (1). Stable disease was observed in 25.8% of acute myeloid leukemia (AML) patients and 38.5% of high-risk MDS patients. Partial remission was seen in one patient with chronic myelomonocytic leukemia (CMML) and peripheral hematologic response in one AML patient and one CMML patient. The study was registered under NCT02158858.
