The Japanese Ministry of Health, Labour, and Welfare (MHLW) has approved Merck & Co Inc's (NYSE:MRK) Keytruda/Lenvima combo therapy for radically unresectable or metastatic renal cell carcinoma (RCC). 

• Lenvima is an orally available multiple receptor tyrosine kinase inhibitor discovered by Eisai Co Ltd (OTC:ESALY).
• Keytruda Plus Lenvima is also approved in the U.S. and Europe for the first-line treatment of adult patients with advanced RCC. 
• This marks the second approval of this combination in Japan; in December 2021, Keytruda/Lenvima combo was approved for unresectable, advanced, or recurrent endometrial carcinoma that progressed after chemotherapy.
• The approval is based on the pivotal Phase 3 CLEAR (Study 307)/KEYNOTE-581 trial. 
• Keytruda plus Lenvima demonstrated statistically significant improvements versus sunitinib in the primary efficacy outcome of progression-free survival (PFS).
