    Safety and efficacy of etigilimab (anti-TIGIT) with nivolumab (anti-PD1) in recurrent/advanced solid tumors (ESMO 2023)
    Table: 1021MO Best Observed Response (BOR)1 - Days on study Cohorts -n Complete Response (CR) Partial response (PR) Stable disease (SD) Progressive disease (PD) CPI-n Cervical Cancer - 8 CPS>1% 3 pts – 163, 365, 386 2 pts – 174, 241 3 pts CPI-n Uveal Melanoma - 8 2 pts – 228, 608 2 pts – 175, 294 4 pts Dedifferentiated Liposarcoma - 10 1 pt – 512 4 pts – 162, 167, 191, 216 5 pts EC – CPI-n - 10 3 pts – 168, 2882, 394 3 pts – 120, 131, 378 4 pts GCT - 4 1 pt – 3722 3 pts Total = 40 (%) 3 pts (7.5) 7 pts (17.5) 11 pts (27.5) 19 pts (47.5) Conclusions Etig in combination with nivo is safe and well tolerated. Preliminary efficacy data of prolonged on study duration with clinical benefit in immune resistant tumors supports continued evaluation in tumor types not typically responsive to anti-PD(L)1 monotherapy.

    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.

    Interim biomarker analysis of a phase Ib/II study of anti-TIGIT etigilimab (MPH313) and nivolumab in subjects with select locally advanced or metastatic solid tumors (ACTIVATE) (ESMO 2022)
    Additionally, reduction in ctDNA levels were noted in some subjects between Days 36 – Days 78. Conclusions These interim biomarker data from Etig+nivo combination therapy demonstrated robust target engagement and evidence of dual TIGIT/PD-1 blockade as seen by decreases in TIGIT hi cells (e.g., Tregs) and an associated increase in proliferating and cytokine producing T-cells in circulation.

    A Phase 1a/b Open‑Label, Dose‑Escalation Study of Etigilimab Alone or in Combination with Nivolumab in Patients with Locally Advanced or Metastatic Solid Tumors. (PubMed, Clin Cancer Res)
    Etigilimab had an acceptable safety profile with preliminary evidence of clinical benefit alone and in combination with nivolumab and warrants further investigation in clinical trials.
