Association of biomarkers with response to vibostolimab coformulated with pembrolizumab in 2 cohorts of the phase 2 KEYVIBE-005 study (SITC 2024)
Background In the multicohort phase 2 KEYVIBE-005 study (NCT05007106), the antitumor activity of vibostolimab (anti-T-cell immunoreceptor with Ig and ITIM domains [TIGIT]) coformulated with pembrolizumab (anti–PD-1; vibostolimab/pembrolizumab) was demonstrated in patients with previously treated advanced mismatch repair–deficient (dMMR) endometrial cancer (cohort B1; n = 40; ORR, 64%) and in patients with previously untreated advanced esophageal cancer treated with vibostolimab/pembrolizumab plus 5-fluorouracil and cisplatin (cohort E; n = 40; ORR, 53%). Ethics Approval The study protocol and all amendments were approved by the institutional review board or ethics committee at each institution. Consent All patients provided written informed consent.

Development and evaluation of nanobody tracers for noninvasive nuclear imaging of the immune-checkpoint TIGIT. (PubMed, Front Immunol)
In addition, we designed a single-chain variable fragment derived from the clinically tested monoclonal antibody Vibostolimab targeting TIGIT, and assessed its performance alongside the nanobodies...The excellent affinity, high specificity and rapid on-target uptake in mice bearing TIGIT- overexpressing tumors showed the promising diagnostic potential of nanobodies to noninvasively image high TIGIT expression within the tumor. These findings hold promise for clinical translation to aid patient selection and improve therapy response.

TIGIT immune checkpoint blockade enhances immunity of human peripheral blood NK cells against castration-resistant prostate cancer. (PubMed, Cancer Lett)
Vibostolimab also increased T cell chemotaxis induced by activated NK cells in vitro and in vivo. Overall, blocking TIGIT/CD155 signaling enhances the antitumor effect of expanded NK cells against CRPC; this finding supports the translational application of TIGIT mAb and NK cell combination strategies from bench to bedside for CRPC treatment.

Anti-TIGIT therapies for solid tumors: a systematic review. (PubMed, ESMO Open)
Vibostolimab was evaluated in a phase I alone or in combination with pembrolizumab...Etigilimab was tested in a phase I alone or in combination with nivolumab, but the study was stopped due to business reasons. In the phase II CITYSCAPE trial, tiragolumab demonstrated higher objective response rate and progression-free survival in combination with atezolizumab than atezolizumab alone in advanced PD-L1-high NSCLC...Anti-TIGIT antibodies are under development as a novel immunotherapy approach. A promising research area includes the combination with anti-PD-1 therapies in advanced NSCLCs.

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.

Safety and Efficacy of Vibostolimab and Pembrolizumab in Patients with Relapsed or Refractory Hematologic Malignancies: A Multicohort, Open-Label, Phase 2 Study (ASH 2021)
Background: The T-cell immunoglobulin and ITIM domain (TIGIT) is highly coexpressed with programmed cell death 1 (PD-1) on both CD4 and CD8 T cells in cancers. In the part 2 dose-expansion phase, the plan is to enroll approximately 120 patients from cohorts B-E to receive up to 35 cycles of MK-7684A Q3W; 30 additional patients may be enrolled in a cohort expansion (cohort G) to receive vibostolimab monotherapy Q3W for up to 35 cycles. Cohort G will include patients with cHL or PMBCL with PD after ≥2 or ≥3 prior therapies, FL after ≥2 prior therapies, DLBCL after ≥2 prior therapies, and/or MM after ≥3 prior therapies.
