QLF4113 in Participants With Metastatic Prostate Cancer
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.
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.

Tidsramme |
|---|---|---|
|
Maximum tolerated dose (MTD) (Phase Ia)
Tidsramme: From first dose of study treatment until the end of Cycle 1 (21 days)
|
Maximum tolerated dose is defined as the previous dose level at which 2 or more out of 2-6 participants experienced a dose-limited toxicity (DLT).
|
From first dose of study treatment until the end of Cycle 1 (21 days)
|
|
Maximum administered dose (MAD)(Phase Ia)
Tidsramme: From first dose of study treatment until the end of Cycle 1 (21 days)
|
MAD is defined as follows: a) based on PK data, it is anticipated that at this dose level, the dose-exposure plateau has been reached, b) based on existing safety data, it is judged that dose escalation following this dose level will have a large safety risk or subject intolerance, or c) based on the PK-PD model, it suggested that the optimal target concentration of safety and efficacy has been explored.
|
From first dose of study treatment until the end of Cycle 1 (21 days)
|
|
recommended phase II dose (RP2D)
Tidsramme: Through phase Ia completion, approximately 1 year.
|
The RP2D will be comprehensively evaluated based on the safety, PK characteristics, and efficacy data from the Phase Ia study.
|
Through phase Ia completion, approximately 1 year.
|
|
The incidence and severity of adverse events (AE) (Phase Ib)
Tidsramme: Through phase Ia completion, approximately 1 year.
|
Incidence and severity of adverse events (AEs) evaluated according to the National Cancer Institute (NCI)-Common Terminology Criteria for Adverse Events (CTCA) Version 6.0 (v6.0) and American Society for Transplantation and Cellular Therapy (ASTCT)
|
Through phase Ia completion, approximately 1 year.
|
|
PSA50 response (Phase Ib)
Tidsramme: From Screening to confirmed progressive disease (approximately 1 year)
|
Best response until progression, as defined by Response Evaluation Criteria in Solid Tumors (RECIST) version (v1.1) and Prostate Cancer Clinical Trials Working Group 3 (PCGW3).
|
From Screening to confirmed progressive disease (approximately 1 year)
|
|
Objective response rate (ORR) (phase Ib)
Tidsramme: From Screening to confirmed progressive disease (approximately 1 year)
|
From Screening to confirmed progressive disease (approximately 1 year)
