Locally Advanced or Metastatic Solid Tumors
Conditions
Brief summary
This study is an Open-Label, Phase 1/2a, First-in-Human, Dose-Escalation, Dose-Expansion, and Proof-of-Concept Study to Investigate Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, and Efficacy of DA-4505 as a Single Agent and in Combination With Pembrolizumab in Adult Patients With Locally Advanced or Metastatic Solid Tumors.
Interventions
Phase 1a: Dose escalation Phase 1b: OBD and MTD Phase 2a: RP2D
Phase 1a/b: OBD, MTD of DA-4505 + 200mg of Pembrolizumab Phase 2a: RP2D of DA-4505 + 200mg of Pembrolizumab

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Proportion of adverse events (AEs) meeting protocol-defined dose-limiting toxicity(DLT) criteria | Cycle 1(21 days) in dose escalation | The recommended Phase 2 dose(RP2D) will be the optimal biological dose (OBD) based on consideration of safety and tolerability information along with all available pharmacokinetic (PK), pharmacodynamic (PD), and efficacy data. |
| PK parameters for DA-4505 (Peak Plasma Concentration (Cmax)) | Day 1 and 2 of first 2 cycles (every 21 days) | Determine DA-4505 Cmax |
| PK parameters for DA-4505 (Area Under the Curve (AUC)) | Day 1 and 2 of first 2 cycles (every 21 days) | Determine DA-4505 AUC |
| PK parameters for DA-4505 (half-life (t1/2)) | Day 1 and 2 of first 2 cycles (every 21 days) | Determine DA-4505 half-life (t1/2). |
| Response per revised Response Evaluation Criteria in Solid Tumors (RECIST) version (v) 1.1) | approximately 12 months | To determine the anti-tumor activity of both DA-4505 as a single agent and in combination with pembrolizumab |
