FC084CSA combined with tislelizumab for advanced solid tumors

Official title: A Dose-Escalation and Dose-Expansion Study of the Safety, Tolerability, Pharmacokinetics and Efficacy of AXL Inhibitor FC084CSA Tablets in Combination With Tislelizumab in the Treatment of Advanced Malignant Solid Tumors

Run by FindCure Biosciences (ZhongShan) Co., Ltd. · NCT06499350 · Data updated 2026-11-12

This trial tests whether adding the experimental drug FC084CSA to the immunotherapy tislelizumab helps adults (18–75) with advanced solid tumors that have progressed after standard treatments.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults 18–75 with histologically or cytologically confirmed advanced solid tumors (and for phase IIa, stage IIIB/IIIC/IV NSCLC without actionable mutations) who have measurable disease per RECIST 1.1, ECOG 0–1, adequate organ function, and prior failure of standard therapies (including prior PD‑1/PD‑L1 plus platinum in the NSCLC expansion).

Probably not a fit

Patients who have not recovered from prior treatment toxicities (≥ CTCAE grade 1), received anti‑tumor therapy or participated in another investigational trial within 4 weeks, have actionable mutations with approved targeted therapies, poor performance status, or significant comorbidities are unlikely to benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This open-label phase Ib/IIa study uses a 3+3 dose-escalation design to establish the recommended Phase 2 dose (RP2D) of FC084CSA given with a fixed dose of tislelizumab and to characterize safety, tolerability, and pharmacokinetics. After dose escalation, a phase IIa dose-expansion cohort will treat patients at the RP2D to observe preliminary antitumor activity. Eligible patients include adults with advanced malignant solid tumors who have failed standard therapy, with a focused expansion for advanced NSCLC without actionable mutations who previously failed PD‑1/PD‑L1 plus platinum therapy. Key assessments include adverse events, pharmacokinetic sampling, and tumor response measured by RECIST 1.1.

Why it matters

Potential benefit: If successful, the combination could provide a new treatment option that improves responses and disease control for patients with advanced solid tumors who have limited options.

How similar studies have gone: Other early‑phase studies combining novel agents with PD‑1 inhibitors have shown encouraging signals in some tumor types, but FC084CSA is a novel agent and its combination with tislelizumab is not yet proven.
