Merck announced on March 1 the voluntary withdrawal of the U.S. indication for Keytruda (pembrolizumab) for the treatment of patients with metastatic small cell lung cancer (SCLC) with disease progression on or after platinum-based chemotherapy and at least one other prior line of therapy.

The U.S. Food and Drug Administration approved Jazz Pharmaceuticals and company partner PharmaMar’s Zepzelca (lurbinectedin) for adults with metastatic small cell lung cancer whose disease has progressed on or after platinum-based chemotherapy.

The cancer treatment Imfinzi was shown to prolong survival in a particularly aggressive type of lung cancer by close to three months in a late-stage clinical trial, as AstraZeneca holds the British drugmaker’s ground in a crowded field against rival immunotherapy drugs.

Amgen Inc. and The University of Texas MD Anderson Cancer Center announced two multi-year collaborative research deals for a broad range of cancer therapeutics. The cancers studied will include leukemia, myelodysplastic syndromes (MDS), multiple myeloma, small-cell lung cancer, and other non-lung cancers with small-cell histologies.

Bristol-Myers Squibb Co. said the U.S. Food and Drug Administration approved a four-week dosing schedule for its cancer drug Opdivo.
