Overview
Brief Summary
A Phase 1 study to evaluate the safety, tolerability, PK, immunogenicity, pharmacodynamics, and preliminary antitumor activity of AK127 in combination with AK104.
Detailed Description
This is a , Phase 1, first-in-human, multicenter, open label, dose escalation and dose expansion study designed to evaluate the safety, tolerability, PK, immunogenicity, pharmacodynamics, and preliminary antitumor activity of AK127 in combination with AK104 in subjects with advanced and metastatic solid tumours. The study comprises of 2 phases: a dose escalation phase and a dose expansion phase. Dose escalation for AK127 will occur using the 3+3+3 model given with a fixed regimen of AK104. Dose expansion will open at the discretion of the Sponsor.

Outcomes
Primary Outcomes
Incidence and Nature of Adverse Events (AEs)
Time Frame: From the time of informed consent signed through to 90 days after end of treatment
An AE is defined as any untoward medical occurrence in a participant administered a pharmaceutical product temporally associated with the use of study treatment, whether or not considered related to the study treatment.
Number of participants with a Dose Limiting Toxicity (DLT)
Time Frame: Within the first six weeks of treatment
DLTs will be assessed during the first treatment cycle and assessed as having a suspected relationship to study drug according to pre-specific criteria in the protocol.
Secondary Outcomes
- Objective response rate (ORR)(Up to 2 years)
- Disease control rate (DCR)(Up to 2 years)
- Progression-free survival (PFS)(Up to 2 years)
- Overall survival (OS)(Up to 2 years)
- Area under the curve (AUC) of AK127+AK104 for assessment of pharmacokinetics(From first dose of treatment through to 90 days after end of treatment)
- Maximum observed concentration (Cmax) of AK127 + AK104(From first dose of treatment through to 90 days after end of treatment.)
- Minimum observed concentration (Cmin) of AK127+AK104(From first dose of treatment through to 90 days after end of treatment)
- Number of subjects who develop detectable anti-drug antibodies (ADAs)(From first dose of treatment through to 90 days after end of treatment)
