On 2 April 2026, MSD announced that the European Commission has approved Keytruda® (pembrolizumab) in combination with paclitaxel, with or without bevacizumab, for the treatment of platinum resistant epithelial ovarian, fallopian tube, or primary peritoneal carcinoma in adults whose tumours express PDL1 with a CPS ≥ 1 and who have received one or two prior systemic treatment regimens.
The EC approval follows a CHMP positive opinion in February 2026 for the indication, which was also approved by the FDA in February 2026 in both IV (Keytruda®) and subcutaneous (Keytruda Qlex™) formulations.
Pembrolizumab biosimilars have reportedly been launched in Paraguay (by Bioeticos in August 2025) and approved in Vietnam (by Biocad in November 2025). Pembrolizumab biosimilars are also under development including by Samsung Bioepis, Amgen, mAbxience, Sandoz, Celltrion, Bio-Thera, BioNTech, Alvotech and Formycon.
