About this trial

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.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Have a histologically and/or cytologically confirmed advanced or metastatic solid tumor and have failed or are intolerant to standard therapy with clinical benefit.

Patients in the Dose-Escalation Part must have evaluable or measurable disease at baseline and the patients for Dose-Ranging and Dose-Expansion Part must have at least one measurable lesion at baseline by computed tomography (CT) or magnetic resonance imaging (MRI) per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1.

Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 assessed within 7 days before allocation or randomization.

Age of 18 years or older (or country's legal age of majority if the legal age was >18 years)

Disqualifiers

Received prior treatment with agent targeting the IL-2, IL-7, or IL-15 receptors, or related to mode of action of HM16390.

Known active CNS metastases and/or carcinomatous meningitis.

History of severe toxicities associated with a prior immunotherapy.

Any prior treatment-related (i.e. chemotherapy, immunotherapy, radiotherapy) clinically significant toxicities that have not resolved to Grade ≤ 1 per NCI-CTCAE version 5.0 or prior treatment-related toxicities that are clinically unstable and clinically significant at time of enrollment.
