Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a First-in-Human, Phase 1, Dose-Escalation and Dose-Expansion study of HM16390, as a single agent and in combination with pembrolizumab to assess safety, tolerability, MTD, RP2D, PK, and efficacy in patients with advanced or metastatic solid tumors.

Dose-Escalation Part is planned to establish the MTD or RDs for the randomized Dose-Ranging Part. Based on the results of the Dose-Escalation Part, additional eligible subjects will be randomized 1:1 into each dose level. After a comprehensive review of available data from both Dose-Escalation Part and Dose-Ranging Part, the RDEs to be tested in the Dose-Expansion Part are determined. Dose-Expansion Part is designed to assess the potential efficacy of HM16390 as a single agent and in combination with pembrolizumab when administered at the RDEs to subjects in indication-specific expansion cohorts.

Intervention Model

PARALLEL

1. Dose-Escalation Part: Divided into 2 arms (Arm A: HM16390 monotherapy, Arm B: HM16390 in combination with pembrolizumab)
2. Dose-Ranging Part: Subjects will be randomized 1:1 into at least two dose levels to enable better selection of the doses for further evaluation, and may apply to cohorts of both monotherapy and combination therapy
3. Dose-Expansion Part: Based on the available data from Dose-Escalation and Dose-Ranging parts, the most feasible dose will be selected as the RDE and will be administered to subjects in indication-specific expansion cohorts
