Official title
An Open-label, Multicenter Phase I Clinical Trial to Evaluate the Safety, Tolerability, Pharmacokinetics, and Preliminary Antitumor Activity of QLF4113 for Injection in Participants With Metastatic Prostate Cancer.
Overview
This is an open-label, dose-escalation and expansion Phase I clinical trial designed to evaluate the safety, tolerability, pharmacokinetic (PK) profile, immunogenicity, and preliminary antitumor activity of QLF4113 monotherapy in participants with metastatic prostate cancer. The Phase I trial consists of two parts: Phase Ia and Phase Ib. Phase Ia is a dose-escalation study of QLF4113 monotherapy to determine the recommended phase two dose and assess safety and PK. Then the study will proceed to Phase Ib, a dose-expansion study to further evaluate the preliminary efficacy and safety of QLF4113 monotherapy under the selected doses.
Interventions
- Drug QLF4113 for injection
A PSMA/CD3/CD2 antibody
Primary outcome measures
- Maximum tolerated dose (MTD) (Phase Ia) [Time frame: From first dose of study treatment until the end of Cycle 1 (21 days)]
- Maximum administered dose (MAD)(Phase Ia) [Time frame: From first dose of study treatment until the end of Cycle 1 (21 days)]
- recommended phase II dose (RP2D) [Time frame: Through phase Ia completion, approximately 1 year.]
- The incidence and severity of adverse events (AE) (Phase Ib) [Time frame: Through phase Ia completion, approximately 1 year.]
- PSA50 response (Phase Ib) [Time frame: From Screening to confirmed progressive disease (approximately 1 year)]
- Objective response rate (ORR) (phase Ib) [Time frame: From Screening to confirmed progressive disease (approximately 1 year)]
