Merck Gains Keytruda Approval in Hodgkin Lymphoma
FDA has approved Merck’s Keytruda (pembrolizumab) for treating adult and pediatric patients with refractory classical Hodgkin lymphoma (cHL), or who have relapsed after three or more prior lines of therapy. The accelerated approval was based on tumor response rate and durability of response, according to the company. Data from a clinical trial (KEYNOTE-087) involving 210 patients demonstrated an overall response rate with KEYTRUDA (200 mg every three weeks) of 69% with a complete remission rate of 22% and a partial remission rate of 47%, Merck says.
Keytruda is currently approved for the first-line treatment of patients with metastatic non-small cell lung cancer (NSCLC) whose tumors have high PD-L1 expression (tumor proportion score of 50% or more) as determined by an FDA-approved test, with no EGFR or ALK genomic tumor aberrations; and for the treatment of patients with metastatic NSCLC whose tumors express PD-L1 (TPS of 1% or more) as determined by an FDA-approved test, with disease progression on or after platinum-containing chemotherapy.
