TOKYO and KENILWORTH, N.J., December 24, 2021 – Eisai (Headquarters: Tokyo, CEO: Haruo Naito) and Merck & Co., Inc., Kenilworth, N.J., U.S.A. (known as MSD outside the United States and Canada) today announced that the Japanese Ministry of Health, Labour and Welfare (MHLW) has approved the combination of LENVIMA, the orally available multiple receptor tyrosine kinase inhibitor discovered by Eisai, plus KEYTRUDA, the anti-PD-1 therapy from Merck & Co., Inc., Kenilworth, N.J., U.S.A., for the treatment of patients with unresectable, advanced or recurrent endometrial carcinoma that progressed after cancer chemotherapy. This approval marks the first time the combination of LENVIMA plus KEYTRUDA has been approved in Japan. LENVIMA plus KEYTRUDA is now approved in Japan, the U.S. and Europe for certain types of advanced endometrial carcinoma.

“Rates of endometrial carcinoma have been steadily increasing in Japan each year1, and there are limited options for patients who are diagnosed at an advanced stage or find their disease has returned,” said Dr. Gregory Lubiniecki, Vice President, Clinical Research, Merck & Co., Inc., Kenilworth, N.J., U.S.A. Research Laboratories. “With today’s approval, patients in Japan with unresectable, advanced or recurrent endometrial carcinoma now have the option of the first immunotherapy and tyrosine kinase inhibitor combination that has significantly improved overall survival and progression-free survival compared to chemotherapy.”

“This is the first approval of the LENVIMA plus KEYTRUDA combination in Japan,” said Terushige Iike, President of Eisai Japan, Senior Vice President, Eisai. “We thank the patients, families and healthcare providers who made this approval possible. By delivering this combination therapy, we are proud to provide patients with advanced or recurrent endometrial carcinoma an additional treatment option.”

The approval is based on results from the pivotal Phase 3 Study 309/KEYNOTE-775 trial, in which LENVIMA plus KEYTRUDA demonstrated statistically significant improvements in overall survival (OS), reducing the risk of death by 38% (HR=0.62 [95% CI, 0.51-0.75]; p<0.0001), and progression-free survival (PFS), reducing the risk of disease progression or death by 44% (HR=0.56 [95% CI, 0.47-0.66]; p<0.0001), versus chemotherapy (investigator’s choice of doxorubicin or paclitaxel). The median OS was 18.3 months (95% CI, 15.2-20.5) for LENVIMA plus KEYTRUDA versus 11.4 months (95% CI, 10.5-12.9) for chemotherapy. The median PFS was 7.2 months (95% CI, 5.7-7.6) for LENVIMA plus KEYTRUDA versus 3.8 months (95% CI, 3.6-4.2) for chemotherapy.

The Japanese package inserts for KEYTRUDA and LENVIMA note that in the Study 309/KEYNOTE-775 trial, adverse reactions were observed in 395 patients (97.3%) out of the safety analysis set of 406 patients (including 51 out of 52 Japanese patients) receiving LENVIMA銆赌 plus KEYTRUDA. The most common adverse reactions were hypertension in 249 patients (61.3%), hypothyroidism in 222 patients (54.7%), diarrhea in 171 patients (42.1%), nausea in 158 patients (38.9%), decreased appetite in 151 patients (37.2%), fatigue in 113 patients (27.8%), proteinuria in 105 patients (25.9%), vomiting in 98 patients (24.1%), weight decreased in 91 patients (22.4%), arthralgia in 87 patients (21.4%) and palmar-plantar erythrodysesthesia syndrome in 84 patients (20.7%).

Endometrial carcinoma begins in the inner lining of the uterus, which is known as the endometrium, and accounts for more than 90% of uterine cancers2. In Japan, it is estimated there were more than 17,000 new cases of uterine cancer and more than 3,000 deaths in 2020 alone3. LENVIMA and KEYTRUDA have each received orphan drug designation in Japan for endometrial carcinoma.
In addition to advanced endometrial carcinoma, Eisai and Merck & Co., Inc., Kenilworth, N.J., U.S.A. continue to study the LENVIMA plus KEYTRUDA combination across several types of cancer with more than 20 clinical trials.

爱豆传媒 Study 309/KEYNOTE-775 Trial
The approval was based on data from Study 309/KEYNOTE-775 (), a Phase 3 multicenter, open-label, randomized, active-controlled study conducted in 827 patients (including 104 Japanese patients) with advanced endometrial carcinoma who had been previously treated with at least one prior platinum-based chemotherapy regimen in any setting, including in the neoadjuvant and adjuvant settings. The primary efficacy outcome measures were OS, and PFS as assessed by blinded independent central review (BICR) according to RECIST v1.1.
銆赌銆赌
Patients were randomized 1:1 to receive LENVIMA (20 mg orally once daily) plus KEYTRUDA (200 mg intravenously every three weeks) or investigator’s choice, consisting of either doxorubicin (60 mg/m2 every three weeks) or paclitaxel (80 mg/m2 given weekly, three weeks on/one week off). Treatment with LENVIMA plus KEYTRUDA continued until RECIST v1.1-defined progression of disease as verified by BICR, unacceptable toxicity, or for KEYTRUDA, a maximum of 24 months. Administration of LENVIMA plus KEYTRUDA was permitted beyond RECIST-defined disease progression if the treating investigator considered the patient to be deriving clinical benefit and the treatment was tolerated.

LENVIMA, discovered and developed by Eisai, is an orally available kinase inhibitor that 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.

Currently, LENVIMA has been approved for monotherapy as a treatment for thyroid cancer in over 75 countries including Japan, in Europe, China and in Asia, and in the United States for locally recurrent or metastatic, progressive, radioiodine-refractory differentiated thyroid cancer. In addition, LENVIMA has been approved for monotherapy as a treatment for unresectable hepatocellular carcinoma in over 70 countries including Japan, in Europe, China and in Asia, and in the United States for first-line unresectable hepatocellular carcinoma. LENVIMA has been approved for monotherapy as a treatment for unresectable thymic carcinoma in Japan. It is also approved in combination with everolimus as a treatment for renal cell carcinoma following prior antiangiogenic therapy in over 60 countries, including in Europe and Asia, and in the United States the treatment of adult patients with advanced renal cell carcinoma following one prior anti-angiogenic therapy. In Europe, the agent was launched under the brand name Kisplyx® for renal cell carcinoma. LENVIMA has been approved in combination with KEYTRUDA (generic name: pembrolizumab), for the first-line treatment of adult patients with advanced renal cell carcinoma (RCC) in United States and in Europe. LENVIMA has been approved in combination with KEYTRUDA as a treatment for advanced endometrial carcinoma that is not microsatellite instability-high (MSI-H) or mismatch repair deficient (dMMR) who have disease progression following prior systemic therapy in any setting and are not candidates for curative surgery or radiation in the United States, and has been approved for the similar indication (including conditional approval) in over 10 countries such as Canada and Australia. In some regions, continued approval for this indication is contingent upon verification and description of clinical benefit in the confirmatory trials. In Europe, it has been approved in combination with KEYTRUDA (generic name: pembrolizumab) as the treatment of advanced or recurrent endometrial carcinoma in adults who have disease progression on or following prior treatment with a platinum containing therapy in any setting and who are not candidates for curative surgery or radiation. In Japan, it is approved in combination with KEYTRUDA (generic name: pembrolizumab) as the treatment of patients with unresectable advanced or recurrent endometrial carcinoma that progressed after cancer chemotherapy.

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 & Co., Inc., Kenilworth, N.J., U.S.A. has the industry’s largest immuno-oncology clinical research program. There are currently more than 1,600 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.
