Merck's KEYTRUDA Continues To Show Overall Survival Benefit Over Chemotherapy

Merck (MRK) announced updated results from the phase 3 KEYNOTE-045 trial evaluating KEYTRUDA or pembrolizumab, the company's anti-PD-1 therapy, in patients with locally advanced or metastatic urothelial carcinoma (a type of bladder cancer) with disease progression on or after platinum-containing chemotherapy (post-platinum failure).

Updated data show that with median follow-up of 22.5 months, KEYTRUDA continues to demonstrate an overall survival (OS) benefit over investigator's choice of paclitaxel, docetaxel or vinflunine as a second-line therapy, post-platinum failure, regardless of PD-L1 expression (HR, 0.70 [95% CI, 0.57-0.86], p=0.0003).

Currently, Merck also has the largest immuno-oncology clinical development program in bladder cancer, with 29 trials underway involving KEYTRUDA (pembrolizumab) as monotherapy and in combination, including four registration-enabling studies.
