Official title
A Phase 1, Open-label, Dose-Escalation Study Evaluating the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, and Preliminary Efficacy of D3L-002 (an Anti-TIGIT/Anti-PVRIG Bispecific Antibody) Monotherapy in Subjects With Advanced Solid Tumors
Overview
This is a first-in-human, multicenter, open-label, single-arm, dose-escalation Phase 1 study evaluating the safety, tolerability, pharmacokinetics, pharmacodynamics, immunogenicity, and preliminary antitumor activity of D3L-002 monotherapy in subjects with advanced solid tumors. D3L-002 will be administered as an intravenous infusion every 3 weeks (Q3W) in 21-day cycles. Approximately 24 subjects will be enrolled. Dose escalation will follow a Bayesian Optimal Interval (BOIN) design to determine the maximum tolerated dose (MTD) and recommended Phase 2 dose (RP2D).
Interventions
- Drug D3L-002
D3L-002 is an investigational anti-TIGIT/anti-PVRIG bispecific antibody administered as an intravenous infusion every 3 weeks (Q3W).
