Advanced or Metastatic Solid Tumors
Conditions
Brief summary
This is a First-in-Human, Phase 1, Dose-Escalation and Dose-Expansion study of BH3120, 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 RD for Dose-Expansion part, while Dose-Expansion part is designed to assess potential efficacy of BH3120, as a single agent and in combination with pembrolizumab, when administered at the RD to subjects in indication-specific expansion cohorts.
Interventions
BH3120 will be administered as an IV infusion over 90 minutes on Day 1 of every 3-week treatment cycle
Fixed dose of pembrolizumab will be administered as an IV infusion over 30 minutes on Day 1 of every 3-week treatment cycle

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Incidence, nature, and severity of adverse events and laboratory abnormalities graded per NCI-CTCAE v5.0. | Throughout the study until end of safety follow-up period (90 days after the last treatment) | To evaluate safety and tolerability of BH3120 as a single agent and in combination with pembrolizumab administration |
| Incidence and nature of DLTs | At the end of Cycle 1 (each cycle is 21 days) in Dose-Escalation Part | To evaluate safety and tolerability of BH3120 as a single agent and in combination with pembrolizumab administration |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| The maximum serum concentration (Cmax) | Throughout the study until treatment discontinuation (up to 2-3 years) | To evaluate PK profile upon BH3120 administration |
| The time to reach Cmax (Tmax) | Throughout the study until treatment discontinuation (up to 2-3 years) | To evaluate PK profile upon BH3120 administration |
| The area under the concentration-time curve from time 0 to the last observable concentration (AUClast) | Throughout the study until treatment discontinuation (up to 2-3 years) | To evaluate PK profile upon BH3120 administration |
| The AUC during the dosing interval (AUCtau) | Throughout the study until treatment discontinuation (up to 2-3 years) | To evaluate PK profile upon BH3120 administration |
| The AUC extrapolated to infinity (AUCinf) | Throughout the study until treatment discontinuation (up to 2-3 years) | To evaluate PK profile upon BH3120 administration |
| The terminal half-life (T1/2) | Throughout the study until treatment discontinuation (up to 2-3 years) | To evaluate PK profile upon BH3120 administration |
| The apparent clearance (CL/F) | Throughout the study until treatment discontinuation (up to 2-3 years) | To evaluate PK profile upon BH3120 administration |
| The apparent volume of distribution (Vd/F) | Throughout the study until treatment discontinuation (up to 2-3 years) | To evaluate PK profile upon BH3120 administration |
| Frequency of anti-drug antibodies (ADA) | Throughout the study until treatment discontinuation (up to 2-3 years) | Immunogenicity of BH3120 |
| Objective response rate (ORR) | Throughout the study until disease progression or death whichever occurs first (up to 2-3 years) | ORR will be measured as the proportion of subjects with a confirmed response of complete response (CR) or partial response (PR) as per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 |
| Disease Control Rate (DCR) | Throughout the study until disease progression or death whichever occurs first (up to 2-3 years) | DCR will be measured as the proportion of subject with confirmed CR, PR, or Stable Disease (SD) as per RECIST v1.1 |
| Duration of response (DOR) | Throughout the study until disease progression or death whichever occurs first (up to 2-3 years) | DOR will be measured as the time from initial onset of CR or PR to first radiographic progression as per RECIST v. 1.1 or death from any cause, whichever occurs first. |
| Progression-free survival (PFS) | Throughout the study until disease progression or death whichever occurs first (up to 2-3 years) | PFS will be measured from date of first treatment until date of radiographic progression as per RECIST v.1.1 or until death from any cause, whichever occurs first |
