17 February 2026 - Merck announced today that Health Canada has approved Keytruda SC (pembrolizumab injection), a new subcutaneous formulation of pembrolizumab, Merck's anti–PD-1 therapy.
The approval is based on results from pivotal trial 3475A-D77, which compared pembrolizumab administered subcutaneously with pembrolizumab administered intravenously, both in combination with chemotherapy, in patients with treatment naïve metastatic squamous or non-squamous non-small cell lung cancer with no EGFR, ALK or ROS1 genomic tumour aberrations.
