A Study of FC084CSA in Combination of Tislelizumab in Patients With Advanced Malignant Solid Tumors

Phase 1
Not yet recruiting
Conditions
Advanced Malignant Solid Tumors
Interventions
Drug: FC084CSA+Tislelizumab combination (dose escalation)
Drug: RP2D of FC084CSA+Tislelizumab combination (dose expansion)
Registration Number
NCT06499350
Lead Sponsor
FindCure Biosciences (ZhongShan) Co., Ltd.
Brief Summary

The goal of this clinical trial is to learn the safety, tolerability, pharmacokinetic characteristics and efficacy of FC084CSA in combination with Tislelizumab in patients with advanced malignant solid tumors.

Detailed Description

The study includes two phases. Phase Ib adopts a "3+3" dose escalation design to assess safety and tolerability of increasing dose levels of FC084CSA in combination of fixed dose of Tislelizumab. Phase IIa is the dose expansion phase to further observe the preliminary effectiveness of the recommended Phase 2 Dose of FC084CSA in combination of Tislelizumab.

GroupInterventionDescription
FC084CSA+TislelizumabFC084CSA+Tislelizumab combination (dose escalation)This is a single arm phase I trial in a 3 + 3 dose escalation and cohort expansion design evaluating the safety and tolerability of FC084CSA in combination with Tislelizumab. Increasing dose levels of FC084CSA with fixed dose of Tislelizumab. Dose escalation continues until dose-limiting toxicities (DLT) are observed in one-third of participants. If no DLT occurs, the next cohort will be enrolled at the next planned dose level. If 1 DLT occurs in a cohort, another 3 patients will be treated with the same dose level. Following the definition of the recommended Phase 2 Dose (RP2D) of FC084CSA in dose escalation phase, NSCLC dose expansion cohort is planned to perform a preliminary assessment of the anti-tumour efficacy and to further establish the safety profile of the RP2D of FC084CSA in combination with Tislelizumab.

Primary Outcome Measures
NameTimeMethod
Objective response rate (ORR)Approximately 12 months

To explore the clinical effectiveness. Tumor response based on RECIST 1.1

Determine the Maximum Tolerated Dose (MTD)Approximately 8 months

The highest dose is defined at which no more than 1 of 3 evaluable participants has had a Dose Limiting Toxicity (DLT) according to NCI CTCAE V5.0 criteria and determination by Investigator and Data and Safety Monitoring Committee.

Determine dose-limiting toxicity (DLT)21 days after first dose

Determine the DLT of FC084CSA

Determine the Recommended Phase 2 Dose (RP2D)Approximately 8 months

The RP2D is based upon the review of all available data including safety, pharmacokinetic, preliminary anti-tumor activity, and MTD.

Secondary Outcome Measures
