A Study of Anlotinib Combined With AK105 Injection in Subjects With Microsatellite Instability-High (MSI-H) or Mismatch Repair Deficient (dMMR) Advanced Solid Tumor

A Randomized, Open-label , Multi-cohort, Multicenter, Phase II Study of Anlotinib Combined With AK105 Injection in Subjects With MSI-H or dMMR Advanced Solid Tumor

This study is designed to evaluate the efficacy and safety of Anlotinib combined with AK105 injection or AK105 monotherapy in subjects with MSI-H or dMMR advanced solid tumors. In this study, 138 subjects will be enrolled, and those who met the admission criteria will divide into cohort 1 (anlotinib combined with AK105) and cohort 2 (AK105 ). The first phase of this study is a randomized, open-label, parallel-controlled, multicenter design, in which 30 subjects are randomly enrolled in two cohorts. The second phase is to continue enrollment of cohort 1 or cohort 2 when which cohort has the better clinical benefit than the other one.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Anlotinib+AK105 injection; AK105 200mg intravenously (IV) on day 1 of each 21-day cycle plus Anlotinib capsules given orally in fasting conditions , once daily in 21-day cycle (14 days on treatment from Day 1-14, 7 days off treatment from Day 15-21).	Drug: AK105; AK105 is a humanized monoclonal antibody that specifically binds to PD-1. AK105 has a typical antibody structure and is composed of two lgG1 subtype heavy chains and two kappa subtypes light chains covalently linked by disulfide bonds.; Drug: Anlotinib; A multi-target receptor tyrosine kinase inhibitor.
