Results from KEYNOTE-B98: A phase 1b/2 study of pembrolizumab plus investigational agents in patients with anti-PD-(L)1-refractory extensive-stage small-cell lung cancer (ES-SCLC) (AACR 2024) - P1/2 | "In the KEYNOTE-B98 study of anti-PD-(L)1-refractory ES-SCLC, no new safety signals were identified for the pembro-based combinations investigated. Modest antitumor activity was observed with MK-1308A ± lenvatinib, but no activity for MK-1308A + MK-4830 or for MK-4280A. This study provided proof-of-concept for the feasibility of platform trials in 2L ES-SCLC."

KEYMAKER-U03 sub-study 03A: Triplet investigational combinations of immunotherapy and targeted treatments as first-line therapy for advanced renal cell carcinoma (Eurekalert) - "This sub-study enrolled 353 patients with advanced ccRCC who were randomly assigned to receive one of the following four investigational combinations, or standard treatment, as first-line therapy: Favezelimab-pembrolizumab + lenvatinib; vibostolimab-pembrolizumab + lenvatinib; quavonlimab-pembrolizumab + lenvatinib; pembrolizumab + belzutifan + lenvatinib, or pembrolizumab + lenvatinib....The pembrolizumab-belzutifan-lenvatinib triplet demonstrated promising antitumor activity with an objective response rate (ORR) of 78% and a median progression-free survival (PFS) of 31.8 months as compared to 20.8 months in the reference arm. The pembrolizumab/quavonlimab plus lenvatinib group showed an ORR of 71%, but median PFS was similar to the control arm. The efficacy of the other two combinations was less favorable."
