Summary

This study aims to evaluate the efficacy of CVL218 in combination with Toripalimab injection/Sintilimab injection (Darbersol, Sintilimab) in the treatment of advanced solid tumors. It focuses on assessing the safety, tolerability, and pharmacokinetic profile of a three-drug combination regimen comprising albumin-bound paclitaxel injection (Kealil), paclitaxel injection (Taxol), and Fuquinitinib capsule (Aiutec, Fruquintinib).

Detailed description

This Phase Ib/II clinical study is designed to determine the recommended Phase II dosage of the combination therapy and its initial efficacy. The study consists of two phases: an exploratory phase (Ib) and an extended phase (II), each divided into three stages: the screening period, treatment period, and follow-up period. The screening period occurs 28 days prior to the first dose administration. Three parallel queues were organized, with Phase Ib enrolling 3-6 participants per dose level cohort and Phase II enrolling approximately 20 participants per cohort. In Phase II, subjects must demonstrate evidence of deleterious HRD gene variants (such as BRCA1, BRCA2, PALB2, ATM, CHEK2 variants) or a positive PD-L1 molecular expression level combined score (CPS) of ≥1. Additionally, Phase II participants are required to consent to the provision of sufficient archived or fresh tumor tissue and blood samples for biomarker analysis in the central laboratory, including determination of HRD gene mutation status and PD-L1 expression level (details in Section 7.4). During the treatment period, the three cohorts received CVL218 orally (PO) in combination with a fixed dose of either terriplizumab injection (Toripalimab) or Sintilimab injection (Darbersol, Sintilimab). Additionally, they were administered albumin-bound paclitaxel injection (Kealil)/paclitaxel injection (Taxol)/Fuquintinib capsule (Aiutec, Fruquintinib). CVL218 was administered at two dose levels, ranging from low to high (500 mg, 700 mg), twice daily (BID), during the exploration of cohorts in Phase Ib. After determining the recommended dose of CVL218 in all cohorts of the three-drug combination, this dose level was maintained during Phase II. When CVL218 and the combination were administered on the same day, CVL218 was given first.
