简要总结
This is a prospective, single-arm, open-label，multi-center, phase Ib/II study, aiming to evaluate the efficacy and safety of Fruquintinib combined With Cadonilimab (AK104) and Tegafur，Gimeracil and Oteracil Potassium in patients with locally advanced or metastatic esophageal squamous cell carcinoma after the failure of first-line treatments.
详细描述
Esophageal cancer is a malignant tumor with high incidence and death rate in the world, especially in china, and Esophageal squamous cell carcinoma (ESCC) is the main pathological type of esophageal carcinoma in China. Among patients with advanced or metastatic esophageal squamous cell carcinoma, the addition of immunotherapy to chemotherapy, compared with chemotherapy, significantly improved overall survival and progression-free survival in first-line treatments. Treatment of recurrent or metastatic esophageal squamous cell carcinoma is usually poor. New treatments were needed.Fruquintinib is an orally antiangiogenic agents, which target VEGFR1/2/3. Candonilimab (AK104) is a PD-1/CTLA-4 Bispecific Antibody. A combination of Fruquintinib and Candonilimab (AK104) and s-1 for advanced or metastatic esophageal squamous cell carcinoma could be a novel therapy. Therefore, investigators initialize this phase Ib/II study to explore the efficacy and safety of fruquintinib in combination with Candonilimab (AK104) and S-1 treatment in ESCC patients with after failure in 1st-line treatment.
In dose escalation period, 3-12 patients with Esophageal squamous cell carcinoma will be enrolled. Patients meeting enrollment eligibility will receive 21-day cycles of fruquintinib 2-3 mg qd，D1-14,Q3W； combined with Candonilimab 10 mg/kg，D1，Q3W and S-1 (30mg BID for body surface area <1.25 m2;40mg BID for body surface area ≥1.25 - <1.5 m2;50mg BID for body surface area ≥1.5m2 ；D1-14,Q3W)
Safety information will be collected till disease progression or intolerable toxicity to determine MTD and/or RPTD of fruquintinib combined with Candonilimab and S-1 in patients with Esophageal squamous cell carcinoma .
This period will include the following 2 dose groups from low to high:
A: Fruquintinib 2 mg qd for 2 weeks followed by 1-week break + Candonilimab 10 mg/kg，intravenous infusion，D1, every 3 weeks+ S-1 ,Calculate dosage based on body surface ,30mg for BSA <1.25 m2;40 mg for BSA ≥1.25 - <1.5 m2; 50mg for BSA ≥1.5m2;BID，D1-14，Q3W
