NCT06427239 | Recruiting Phase 1

• 1 other identifier: PANC-2nd-IIT-HRS4642-SHR1316
• Study Type: interventional
• Target: 130
• Locations: 1 country
• Sites: 1

Brief Summary

The study is being conducted to evaluate the safety, tolerability and efficacy of HRS-4642 combined with adebrelimab, or with adebrelimab and other antitumor agents in patients with advanced pancreatic ductal adenocarcinoma (PDAC).

Conditions

Pancreatic Cancer

Outcome Measures

Primary Outcomes (3)

• Dose Limited Toxicity (DLT)

  A DLT is defined as any event meeting the DLT criteria occurring within 21 days of first dose on Cycle 1 Day 1 (C1D1), excluding toxicities clearly related to disease progression or intercurrent illness

  Day 1 to Day 21 after the first combination therapy was administrated

• Recommended phase II dose (RP2D)

  RP2D will be determined on the basis of evaluation on safety and efficacy data in dose escalation stages.

  Approximately 12 months

• Objective Response Rate (ORR)

  Evaluated by RECIST v1.1.

  Up to approximately 12 months

Secondary Outcomes (5)

• Disease Control Rate (DCR)

  Up to approximately 12 months

• Duration of Response (DOR)

  Up to approximately 12 months

• Progression Free Survival (PFS)

  Up to approximately 12 months

• Overall survival (OS)

  Up to approximately 12 months

• Adverse events (AEs)

  From the first drug administration to within 90 days for the last adebrelimab dose
