About

A Phase Ib/II Open-label Clinical Study to Evaluate the Safety, Tolerability and Preliminary Efficacy of AK127 in combination with AK112 in Patients with Advanced Malignant Tumors

Full description

The study consisted of two parts. The first part, Phase Ib is to characterize the safety, tolerability, pharmacokinetics (PK), immunogenicity of AK127 in combination with AK112 in adult subjects with advanced solid tumor malignancies. The part, as a dose escalation phase is to determine the maximum tolerated dose (MTD), or recommended Phase 2 dose (RP2D) for AK127 in combination with AK112, and describe Dose Limiting Toxicity (DLT).The second part, Phase II is to Evaluate the anti-tumor activity of AK127 in combination with AK112 in different tumor species cohorts.

Enrollment: 216 estimated patients

Sex: All

Ages: 18 to 75 years old

Volunteers: No Healthy Volunteers
