Representatives of Merck and Eisai will discuss these results with regulatory authorities.
KEYNOTE 775 PUBLICATION TRIAL
The combination exhibited a safety profile consistent with that observed in prior studies.įull results of the trial will be submitted for presentation at a medical meeting. Researchers observed the benefit of the combination in the subgroup of women with mismatch repair-proficient tumors, as well as in the intention-to-treat population, which included women with endometrial cancer that was mismatch repair proficient and those whose disease was microsatellite instability-high/mismatch repair deficient. The study met its primary endpoints, as well as the secondary endpoint of improved ORR, with the pembrolizumab-lenvatinib combination. Secondary endpoints included objective response rate by blinded independent central review and safety/tolerability. OS and PFS as assessed by blinded independent central review served as the primary endpoints.
Women in the control group received physicians’ choice of IV doxorubicin dosed at 60 mg/m 2 every 3 weeks for a maximum cumulative dose of 500 mg/m 2, or IV paclitaxel dosed at 80 mg/m 2 in 28-day cycles (3 weeks on, 1 week off).
KEYNOTE 775 PUBLICATION PLUS
Researchers assigned women in the experimental group to pembrolizumab dosed at 200 mg via IV every 3 weeks for up to 35 cycles plus lenvatinib dosed at 20 mg orally once daily. The multicenter, open-label KEYNOTE-775/Study 309 trial included 827 women with advanced endometrial cancer who received at least one prior platinum-based regimen. The FDA granted accelerated approval to the combination in 2019 for treatment of women with advanced endometrial carcinoma that is not microsatellite instability-high or mismatch repair deficient, or whose disease progressed after prior systemic therapy and who are not candidates for curative surgery or radiation.
Pembrolizumab (Keytruda, Merck) is an anti-PD-1 antibody, and lenvatinib (Lenvima, Eisai) is a multiple receptor tyrosine kinase inhibitor. Women assigned the combination achieved longer OS and PFS and were more likely to respond to therapy, results of the randomized phase 3 KEYNOTE-775/Study 309 trial showed. Pembrolizumab plus lenvatinib improved outcomes compared with chemotherapy for women with advanced endometrial cancer, according to topline data released by the agents’ manufacturers.
