KEYSTEP-008: phase II trial of pembrolizumab-based combination in MSI-H/dMMR metastatic colorectal cancer. (PubMed, Future Oncol)
Here we describe the design and rationale for the open-label, randomized, phase II KEYSTEP-008 trial, which will evaluate the efficacy and safety of pembrolizumab-based combination therapy compared with pembrolizumab monotherapy in chemotherapy-refractory (cohort A) or previously untreated (cohort B) MSI-H/dMMR mCRC. Clinical Trial Registration: NCT04895722 (ClinicalTrials.gov).

Biomarker-directed, pembrolizumab-based combination therapy in non-small cell lung cancer: phase 2 KEYNOTE-495/KeyImPaCT trial interim results. (PubMed, Nat Med)
Patients were categorized by T-cell-inflamed gene expression profile (TcellGEP) and tumor mutational burden (TMB) status and randomly assigned 1:1:1 to receive pembrolizumab + lenvatinib, pembrolizumab + quavonlimab or pembrolizumab + favezelimab. These data demonstrate the feasibility of prospective TcellGEP and TMB assessment to study the clinical activity of first-line pembrolizumab-based combination therapies in advanced NSCLC.

Phase 2 study of pembrolizumab-based combination therapy in patients with microsatellite instability-high (MSI-H) or mismatch repair-deficient (dMMR) stage IV colorectal cancer (CRC). (ASCO 2022)
This ongoing, open-label, multicenter, multiarm, randomized, phase 2 trial (NCT04895722) will evaluate efficacy and safety of coformulated pembro and anti–CTLA-4 quavonlimab compared with pembro monotherapy in chemotherapy-refractory stage IV dMMR/MSI-H CRC in cohort A; the study will also evaluate the efficacy and safety of 4 pembro-based combinations (coformulation of pembro with either quavonlimab, anti–LAG-3 favezelimab, or anti-TIGIT vibostolimab; anti-ILT4 MK-4830 given sequentially with pembro) compared with pembro monotherapy in previously untreated stage IV dMMR/MSI-H CRC in cohort B. Pts aged ≥18 y with histologically confirmed stage IV dMMR/MSI-H CRC who have measurable disease per RECIST v1.1 by investigator and confirmed by blinded independent central review (BICR), will be enrolled. Pts in cohort A must have experienced PD after fluoropyrimidine, irinotecan, and oxaliplatin, with or without anti-VEGF antibody, and anti-EGFR antibody for pts with left-sided tumors that are RAS WT...For both cohorts, primary end point is ORR by BICR per RECIST v1.1; secondary end points are ORR assessed by investigator, DOR and PFS assessed by BICR and by investigator per RECIST v1.1, OS, and safety and tolerability graded per NCI CTCAE v5.0. Enrollment in this trial is ongoing.

Anti-cytotoxic T-lymphocyte-associated antigen-4 monoclonal antibody quavonlimab in combination with pembrolizumab: Safety and efficacy from a phase I study in previously treated extensive-stage small cell lung cancer. (PubMed, Lung Cancer)
Encouraging antitumor activity was observed with quavonlimab + pembrolizumab in patients with extensive-stage SCLC; responses were observed in PD-L1-positive and PD-L1-negative tumors. The combination was tolerable with manageable toxicities.
