Brief summary

The study of LVGN6051-201 is designed to use a bridging dose escalation to quickly establish the maximum tolerated dose (MTD) and/or the recommended dose for expansion (RDE) as well as the recommended Phase 2 dose(s) (RP2D) of LVGN6051, both as a single agent (monotherapy) and in combination with a fixed dose of anti-PD-1 antibody (Pembrolizumab) in the treatment of advanced or metastatic malignancy.

Detailed description

Based on the dose escalation results from the study of LVGN6051-101, a bridging dose escalation (3+3) is used in study of LVGN6051-201. The traditional 3 + 3 dose escalation algorithm to identify the MTD and/or RDE and RP2D of LVGN6051 as a single agent (monotherapy) and in combination with pembrolizumab. The first stage of the study is the single agent dose escalation and expansion phase (Part A). The second stage of the study is the combination dose escalation and expansion phase (Part B). Patients will be considered evaluable for safety and tolerability if they receive at least one dose of LVGN6051 or pembrolizumab at the specified cohort dose. Patients in all parts of the trial will remain on therapy until confirmed disease progression or for 2 years, whichever occurs first. However, patients who are clinically unstable will discontinue following the initial assessment of disease progression

Interventions

Route of administration is IV infusion, and the frequency of administration is once every 3 weeks (Q3W). one cycle is 3 weeks, and treatment can be up to 35 cycles if patients receive benefits.
