ak105 combined with anlotinib in patients with cervical cancer

Conditions: Cervical Cancer

Summary: the purpose of this study is to evaluate the efficacy and safety of ak105 (anti-pd-1 mab) combined with anlotinib hydrochloride in the treatment of persistent, recurrent and metastatic cervical cancer.

patients with persistent,recurrent or metastatic cervical cancer (histologic types include squamous cell carcinoma, adenocarcinoma, and adenosquamous carcinoma) who had received at least once platinum-based systemic chemotherapy were enrolled.eligible patients receive ak105 200 mg by intravenous (iv.) infusion every 3 weeks (q3w),and anlotinib 12mg 2 weeks on/1 week off orally(q3w).imaging will be performed after the 3th ak105 administration as 3 cycles.this study is an open,single-arm,single-center clinical trial,and all the patients will receive ak105 and anlotinib treatment until radiographic progression,unacceptable toxicity, investigator or patient decision to withdraw, non-adherence to treatment or trial procedures.
