FDA Approves Merck’s KEYTRUDA® (pembrolizumab) Plus Gemcitabine and Cisplatin as Treatment for Patients With Locally Advanced Unresectable or Metastatic Biliary Tract Cancer

Merck (NYSE: MRK), known as MSD outside of the United States and Canada, today announced that the U.S. Food and Drug Administration (FDA) has approved KEYTRUDA, Merck’s anti-PD-1 therapy, in combination with gemcitabine and cisplatin, for the treatment of patients with locally advanced unresectable or metastatic biliary tract cancer (BTC). The approval was based on results from the Phase 3 KEYNOTE-966 trial, in which KEYTRUDA plus chemotherapy demonstrated a statistically significant improvement in the study’s primary endpoint of overall survival (OS), reducing the risk of death by 17% (HR=0.83 [95% CI, 0.72-0.95]; one-sided p=0.0034) compared to chemotherapy alone at the trial’s pre-specified final analysis for OS. Median OS was 12.7 months (95% CI, 11.5-13.6) for KEYTRUDA plus chemotherapy versus 10.9 months (95% CI, 9.9-11.6) for chemotherapy alone. This approval marks the sixth indication for KEYTRUDA in gastrointestinal cancers.

Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue and can affect more than one body system simultaneously. Immune-mediated adverse reactions can occur at any time during or after treatment with KEYTRUDA, including pneumonitis, colitis, hepatitis, endocrinopathies, nephritis, dermatologic reactions, solid organ transplant rejection, and complications of allogeneic hematopoietic stem cell transplantation. Important immune-mediated adverse reactions listed here may not include all possible severe and fatal immune-mediated adverse reactions. Early identification and management of immune-mediated adverse reactions are essential to ensure safe use of KEYTRUDA. Based on the severity of the adverse reaction, KEYTRUDA should be withheld or permanently discontinued and corticosteroids administered if appropriate. KEYTRUDA can also cause severe or life-threatening infusion-related reactions. Based on its mechanism of action, KEYTRUDA can cause fetal harm when administered to a pregnant woman.

“Cancers of the biliary tract can be highly aggressive tumors, underscoring the need for additional treatment options for the growing number of patients facing this challenging disease,” said Dr. Robin Kate Kelley, professor of clinical medicine in the division of hematology/oncology, University of California, San Francisco. “Today’s approval of pembrolizumab in combination with chemotherapy offers patients with locally advanced unresectable or metastatic biliary tract cancer a new immunotherapy regimen that has demonstrated the potential to help these patients live longer.”

“Many patients with biliary tract cancer are diagnosed with locally advanced or metastatic disease, at which point they are not eligible for surgery and face poor survival outcomes with limited treatment options,” said Dr. Marjorie Green, senior vice president and head of late-stage oncology, global clinical development, Merck Research Laboratories. “With this approval, Merck is proud to offer a new treatment option to certain patients with locally advanced unresectable or metastatic biliary tract cancer, and their healthcare providers, that has shown an overall survival benefit compared to chemotherapy alone.”
