About

This study is an open-label, multicenter phase Ib/II study to evaluate the efficacy and safety of LBL-024 monotherapy, LBL-024 in combination with LBL-007 or toripalimab in patients with advanced melanoma,To evaluate the preliminary efficacy and safety of LBL-024 monotherapy and combination therapy in patients with advanced melanoma.

Full description

This trial includes two phases, Phase Ib and Phase II.

Phase Ib is an exploratory stage of safety and efficacy in a single-arm, open-label study, including three cohorts (different dosing regimens).Phase Ib includes three cohorts, Cohort 1 (LBL-024 monotherapy), Cohort 2 (LBL-024 + LBL-007 combination) and Cohort 3 (LBL-024 + toripalimab combination).

Phase II includes Part A and Part B.Part A is a randomized, open-label, positive-controlled extension study. It plans to enroll patients with melanoma of the cutaneous, Acral, and unknown primary. Eligible subjects will be randomly assigned in a 2:1 ratio [Stratification factor: Acral subtype (Yes vs. No)] to either the Experimental Group or the Control Group. Part B is a single-arm extension study enrolling only patients with mucosal melanoma,and will select a drug combination based on phase Ib efficacy for expansion study.

This study requires subjects to provide relevant samples for testing. The trial will enroll up to 200 subjects.
