KEYTRUDA® (pembrolizumab) Plus Platinum-Based Chemotherapy With or Without Bevacizumab Significantly Improved OS and PFS Compared to Platinum-Based Chemotherapy With or Without Bevacizumab Alone as First-Line Treatment, Regardless of PD-L1 Status
KENILWORTH, NJ, USA I June 22, 2021 I Merck (NYSE: MRK), known as MSD outside the United States and Canada, today announced that the pivotal Phase 3 KEYNOTE-826 trial investigating KEYTRUDA, Merck’s anti-PD-1 therapy, in combination with platinum-based chemotherapy (paclitaxel plus cisplatin or paclitaxel plus carboplatin) with or without bevacizumab, met its primary endpoints of overall survival (OS) and progression-free survival (PFS) for the first-line treatment of patients with persistent, recurrent or metastatic cervical cancer. Based on an interim analysis conducted by an independent Data Monitoring Committee, KEYTRUDA plus platinum-based chemotherapy with or without bevacizumab demonstrated statistically significant and clinically meaningful improvements in OS and PFS compared to the same platinum-based chemotherapy regimens with or without bevacizumab alone, regardless of PD-L1 status; KEYTRUDA is the first anti-PD-1/PD-L1 therapy to demonstrate this. The safety profile of KEYTRUDA in this trial was consistent with that observed in previously reported studies. Results will be presented at an upcoming medical meeting and will be submitted to regulatory authorities.
“Despite progress with prevention and screening, cervical cancer continues to be a major health problem, often affecting younger and middle-aged women,” said Dr. Roy Baynes, senior vice president and head of global clinical development, chief medical officer, Merck Research Laboratories. “Women diagnosed with metastatic cervical cancer have a particularly poor prognosis, and there is an urgent need for new treatment options. KEYNOTE-826 is the first study to show positive results for immunotherapy in first-line persistent, recurrent or metastatic cervical cancer, and we look forward to sharing these findings at an upcoming congress and discussing them with regulatory authorities. We thank the patients, their caregivers and investigators for their participation in this important study.”
The Phase 3 KEYNOTE-826 trial is also the confirmatory trial for the current accelerated approval for KEYTRUDA in cervical cancer for the second-line treatment of patients with recurrent or metastatic cervical cancer with disease progression on or after chemotherapy whose tumors express PD-L1 (Combined Positive Score [CPS] ≥1) as determined by an FDA-approved test.
Merck is rapidly advancing a broad portfolio in women’s cancers with an extensive clinical development program for KEYTRUDA and several other investigational and approved medicines across multiple gynecologic and breast cancers.
About KEYNOTE-826
KEYNOTE-826 is a randomized, triple-blind, Phase 3 trial (ClinicalTrials.gov, NCT03635567) evaluating KEYTRUDA in combination with platinum-based chemotherapy (paclitaxel plus cisplatin or paclitaxel plus carboplatin) with or without bevacizumab compared with placebo in combination with the same platinum-based chemotherapy regimens with or without bevacizumab for the first-line treatment of adult patients with persistent, recurrent or metastatic cervical cancer. The trial enrolled adults with persistent, recurrent or metastatic squamous cell carcinoma, adenosquamous carcinoma or adenocarcinoma of the cervix who had not been treated with systemic chemotherapy and who were no longer amenable to curative treatment (such as surgery and/or radiation). The primary endpoints are OS and PFS. The secondary endpoints include objective response rate, duration of response and safety. The study enrolled 617 patients who were randomized to receive:
- KEYTRUDA (200 mg intravenously) plus investigator’s choice of the one of four platinum-based chemotherapy regimens: paclitaxel (175 mg/m2) plus cisplatin (50 mg/m2) with or without bevacizumab (15 mg/kg); or paclitaxel (175 mg/m2) plus carboplatin Area Under the Curve (AUC) 5 with or without bevacizumab (15 mg/kg) on Day 1 of each 21-day cycle for up to 35 cycles (up to approximately two years); or
- Placebo plus investigator’s choice of the one of four platinum-based chemotherapy regimens: paclitaxel (175 mg/m2) plus cisplatin (50 mg/m2) with or without bevacizumab (15 mg/kg); or paclitaxel (175 mg/m2) plus carboplatin AUC 5 with or without bevacizumab (15 mg/kg) on Day 1 of each 21-day cycle for up to 35 cycles (up to approximately two years).
About Cervical Cancer
Cervical cancer forms in the cells lining the cervix, which is the lower part of the uterus. While screenings and prevention have resulted in declining cervical cancer rates, the disease continues to affect many people in the U.S. and around the world. In the U.S., it is estimated there will be nearly 14,500 new cases of invasive cervical cancer diagnosed and almost 4,300 deaths resulting from the disease in 2021. For patients diagnosed in the U.S. with cervical cancer that has spread to a distant part of the body, the five-year survival rate is estimated to be approximately 17%. Worldwide, it is estimated there were more than 604,100 new cases of cervical cancer diagnosed and over 341,800 deaths resulting from the disease in 2020. While cervical cancer can occur in people of any age, it is most often diagnosed in those between 35 to 44 years old.
About KEYTRUDA® (pembrolizumab) Injection, 100 mg
KEYTRUDA is an anti-programmed death receptor-1 (PD-1) therapy that works by increasing the ability of the body’s immune system to help detect and fight tumor cells. KEYTRUDA is a humanized monoclonal antibody that blocks the interaction between PD-1 and its ligands, PD-L1 and PD-L2, thereby activating T lymphocytes which may affect both tumor cells and healthy cells.
Merck has the industry’s largest immuno-oncology clinical research program. There are currently more than 1,500 trials studying KEYTRUDA across a wide variety of cancers and treatment settings. The KEYTRUDA clinical program seeks to understand the role of KEYTRUDA across cancers and the factors that may predict a patient’s likelihood of benefitting from treatment with KEYTRUDA, including exploring several different biomarkers.
