...Eisai...and Merck & Co., Inc.,...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.

Eisai Co...and Merck & Co., Inc...today announced that the European Commission 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 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.

KEYTRUDA is a programmed death receptor-1 (PD-1)-blocking antibody indicated:...in combination with lenvatinib, for the treatment of patients with advanced endometrial carcinoma that is not MSI-H or dMMR, who have disease progression following prior systemic therapy in any setting and are not candidates for curative surgery or radiation.

Systemic Therapy for Endometrial Carcinoma...Recurrent, Metastatic or High-risk Disease...Biomarker-directed systemic therapy for second-line treatment...lenvatinib/pembrolizumab.

Lenvatinib plus pembrolizumab showed benefits in OS (pMMR HR, 0.70; 95% CI, 0.58 to 0.83; all-comer HR, 0.65; 95% CI, 0.55 to 0.77), PFS (pMMR HR, 0.60; 95% CI, 0.50 to 0.72; all-comer HR, 0.56; 95% CI, 0.48 to 0.66), and ORR (pMMR patients, 32.4% v 15.1%; all-comers, 33.8% v 14.7%) versus chemotherapy. OS, PFS, and ORR favored lenvatinib plus pembrolizumab in all subgroups of interest. No new safety signals were observed. Lenvatinib plus pembrolizumab continued to show improved efficacy versus chemotherapy and manageable safety in patients with previously treated advanced EC.

The median progression-free survival was longer with lenvatinib plus pembrolizumab than with chemotherapy (pMMR population: 6.6 vs. 3.8 months; hazard ratio for progression or death, 0.60; 95% confidence interval [CI], 0.50 to 0.72; P<0.001; overall: 7.2 vs. 3.8 months; hazard ratio, 0.56; 95% CI, 0.47 to 0.66; P<0.001). The median overall survival was longer with lenvatinib plus pembrolizumab than with chemotherapy (pMMR population: 17.4 vs. 12.0 months; hazard ratio for death, 0.68; 95% CI, 0.56 to 0.84; P<0.001; overall: 18.3 vs. 11.4 months; hazard ratio, 0.62; 95% CI, 0.51 to 0.75; P<0.001).

The positive CHMP opinions are based on data from two pivotal Phase 3 trials: CLEAR (Study 307)/KEYNOTE-581 evaluating the combination in adult patients with advanced RCC and KEYNOTE-775/Study 309 evaluating the combination in certain patients with advanced EC....KEYTRUDA plus LENVIMA demonstrated statistically significant improvements versus sunitinib in the efficacy outcome measures of overall survival (OS)...

Merck...and Eisai Inc. today announced that the U.S. Food and Drug Administration (FDA) has accepted and granted priority review for applications seeking two new approvals for the combination of KEYTRUDA, Merck’s anti-PD-1 therapy, plus LENVIMA....The second set of applications are for the treatment of patients with advanced endometrial carcinoma who have disease progression following prior systemic therapy in any setting and are not candidates for curative surgery or radiation, based on PFS, OS and ORR data from the pivotal Phase 3 KEYNOTE-775/Study 309 trial.
