Merck and Eisai announce that KEYTRUDA® plus LENVIMA® is now reimbursed with clinical criteria and conditions under the British Columbia, Alberta, Saskatchewan, Ontario, Quebec, Nova Scotia, New Brunswick, and Newfoundland drug plans, for adult patients with advanced endometrial carcinoma that is not microsatellite instability high or mismatch repair deficient, who have disease progression following prior platinum-based systemic therapy, and are not candidates for curative surgery or radiation.
KIRKLAND, QC, and MISSISSAUGA, ON, Dec. 21, 2023 /CNW/ - Merck (NYSE: MRK), known as MSD outside the United States and Canada, and Eisai announce that KEYTRUDA®, Merck’s anti-PD-1 therapy, plus LENVIMA®, an orally available multiple receptor tyrosine kinase inhibitor discovered by Eisai, is now reimbursed with clinical criteria and conditions under the British Columbia, Alberta, Saskatchewan, Ontario, Quebec, Nova Scotia, New Brunswick, and Newfoundland drug plans, for adult patients with advanced endometrial carcinoma (EC) that is not microsatellite instability high (MSI-H) or mismatch repair deficient (dMMR), who have disease progression following prior platinum-based systemic therapy, and are not candidates for curative surgery or radiation.
This announcement follows the notice of compliance issuance from Health Canada in July 2023 based on the results from the Phase 3 Study 309/KEYNOTE-775 trial, which evaluated KEYTRUDA® plus LENVIMA® versus chemotherapy (treatment of physician’s choice of doxorubicin or paclitaxel) in patients with advanced endometrial carcinoma who had been previously treated with at least one prior platinum-based chemotherapy regimen in any setting. KEYTRUDA® plus LENVIMA® demonstrated statistically significant improvements in the dual primary endpoints of overall survival (OS) and progression-free-survival (PFS) compared to chemotherapy.
“Each patient’s journey is unique, and this particular indication addresses an important care gap as it targets individuals that are diagnosed in a late stage setting with limited treatment options,” says Dr. Amit Oza, Head of the Division of Medical Oncology & Hematology, Professor of Medicine, University of Toronto, and Medical Director of the Cancer Clinical Research Unit at Princess Margaret Cancer Centre. “By having an additional therapeutic option in our toolbox, we are better able to tailor treatment plans according to individual needs, which can help improve health outcomes.”
These most recent developments are a result of the strategic collaboration between Merck and Eisai, whose collective mission is to help bring greater access to innovative medicines for patients in need.
“Endometrial cancer is a serious and potentially life-threatening condition affecting many Canadians,” says Patrick Forsythe, Country Manager, Eisai Canada. “We commend Health Canada and the health technology assessment organizations for supporting the approval and availability of KEYTRUDA® plus LENVIMA® to provide an additional treatment option in an area of oncology where cases are rising in this country.”
“This achievement is a result of the relentless work of our researchers and physicians, as well as the commitment of the patients who enroll in these clinical trials,” says André Galarneau, Executive Director & Vice President, Oncology Business Unit at Merck Canada. “It is thanks to them that we can provide more treatment options to Canadians impacted by this disease.”
About STUDY 309/KEYNOTE-775
Study 309/KEYNOTE-775 is a Phase 3 multicenter, open-label, randomized, active-controlled trial that enrolled 827 patients with advanced EC previously treated with at least one prior platinum-based chemotherapy regimen in any setting, including in the neoadjuvant and adjuvant settings. The study excluded certain patients such as those with endometrial sarcoma, including carcinosarcoma, or patients who had active autoimmune disease or a medical condition that required immunosuppression. The primary efficacy outcome measures were OS and PFS as assessed by blinded independent central review (BICR) according to Response Evaluation Criteria in Solid Tumors Version (RECIST) v1.1. Secondary efficacy outcome measures included ORR as assessed by BICR.
There were 697 patients with advanced EC that was not MSI-H or dMMR that were randomized 1:1 to receive pembrolizumab (200 mg intravenously every three weeks) plus lenvatinib (20 mg orally once daily or n=346 ) or investigator’s choice, consisting of either doxorubicin (60 mg/m2 every three weeks; n=254) or paclitaxel (80 mg/m2 given weekly, three weeks on/one week off; n=97). Treatment with pembrolizumab plus lenvatinib continued until RECIST v1.1-defined progression of disease as verified by BICR, unacceptable toxicity, or for pembrolizumab, a maximum of 24 months or up to 35 administrations - whichever was longer. Administration of pembrolizumab plus lenvatinib was permitted beyond RECIST-defined disease progression if the treating investigator considered the patient to be deriving clinical benefit and the treatment was.
The most common adverse events (reported in at least 30% of patients) among these patients receiving pembrolizumab and lenvatinib were hypothyroidism, hypertension, fatigue, diarrhea, musculoskeletal disorders, nausea, decreased appetite, vomiting, stomatitis, abdominal pain, weight loss, and urinary tract infection.
About Endometrial Carcinoma
Endometrial carcinoma (endometrial cancer) begins in the inner lining of the uterus, and makes up more than 95% of all uterine cancer cases. In 2023, an estimated 8,500 Canadian women will be diagnosed with uterine cancer, with a greater tendency to develop in women over the age of 50. Symptoms of endometrial cancer can include abnormal vaginal bleeding, pain during intercourse, difficult or painful urination and pain in the pelvic area.
About KEYTRUDA® (pembrolizumab)
KEYTRUDA® is an anti-PD-1 therapy that works by helping increase the ability of the body’s immune system to help detect and fight tumour 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 tumour cells and healthy cells.
KEYTRUDA® was first approved in Canada in 2015 and currently has indications in several disease areas, including advanced renal cell carcinoma, bladder cancer, non-small cell lung carcinoma, primary mediastinal B-cell lymphoma, classical Hodgkin lymphoma, colorectal cancer, endometrial carcinoma, esophageal cancer, triple-negative breast cancer, melanoma, and head and neck squamous cell carcinoma.
About LENVIMA® (lenvatinib)
LENVIMA®, discovered and developed by Eisai, is an orally available multiple receptor tyrosine kinase inhibitor that selectively inhibits the kinase activities of vascular endothelial growth factor (VEGF) receptors VEGFR1 (FLT1), VEGFR2 (KDR), and VEGFR3 (FLT4). LENVIMA® inhibits other kinases that have been implicated in pathogenic angiogenesis, tumor growth, and cancer progression in addition to their normal cellular functions, including fibroblast growth factor (FGF) receptors FGFR1-4, the platelet derived growth factor receptor alpha (PDGFRα), KIT, and RET. In syngeneic mouse tumor models, LENVIMA® decreased tumor-associated macrophages, increased activated cytotoxic T cells, and demonstrated greater antitumor activity in combination with an anti-PD-1 monoclonal antibody compared to either treatment alone.
