Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a Phase 1/2A non-randomized, open label, multi-center study to be conducted in four parts (Parts A, B, C and D).

In Part A, a 3+3 dose escalation scheme will be used to evaluate the safety and tolerability of GV20-0251, and to establish the maximum tolerated dose (MTD) or the preliminary recommended Phase 2 dose (RP2D).

In Part B, the Bayesian optimal design for Phase II (BOP2) will be utilized to further characterize the anti-tumor activities, safety, tolerability, pharmacokinetics, and pharmacodynamics of GV20-0251 at the preliminary RP2D across multiple expansion cohorts involving eligible participants.

In Part C, the Bayesian optimal interval (BOIN) design will be employed to evaluate the safety and tolerability of GV20-0251 in combination with Pembrolizumab, and to determine the MTD or the preliminary RP2D of this combination.

In Part D, BOP2 will be applied to further characterize the anti-tumor activities, safety, tolerability, pharmacokinetics, and pharmacodynamics of GV20-0251 in combination with Pembrolizumab at the preliminary RP2D across multiple expansion cohorts involving eligible participants.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Part A - Dose Escalation in up to 7 dose levels

A 3+3 dose escalation scheme will be used to evaluate the safety and tolerability of GV20-0251, and to establish the maximum tolerated dose (MTD) or the preliminary recommended Phase 2 dose (RP2D).

Group Type EXPERIMENTAL

GV20-0251

Intervention Type BIOLOGICAL

Increasing doses of GV20-0251 administered by intravenous (IV) infusion once or twice every 3 weeks as monotherapy.

Part B - Multiple Expansion Cohorts in up to 4 tumor indications

The Bayesian optimal design for Phase II (BOP2) will be utilized to further characterize the anti-tumor activities, safety, tolerability, pharmacokinetics, and pharmacodynamics of GV20-0251 at the preliminary RP2D in up to 4 expansion cohorts involving eligible participants.

Group Type EXPERIMENTAL

GV20-0251

Intervention Type BIOLOGICAL
