Study summary
This trial is a Phase II study. The purpose of this study is to evaluate the efficacy, safety, and pharmacokinetics of AK112 with or without AK117 in participants with metastatic colorectal cancer who are not suitable for surgery.
Eligibility
Inclusion Criteria:

* Part1: Subjects who have not previously received any systemic antitumor therapy and who have previously received neoadjuvant or adjuvant therapy, the first detection of recurrence or metastasis should be ≥12 months after the last administration of neoadjuvant or adjuvant therapy
* Part2: Subjects who have previously received systemic therapy including fluorouracil, oxaliplatin, irinotecan, bevacizumab or anti-EGFR antibodies or could not tolerate or have contraindications to standard treatment
* Eastern Cooperative Oncology Group performance status of 0 or 1

Exclusion Criteria:
* Known MSI-H(Microsatellite-Instability-High) or dMMR(Mismatch Repair-Deficient)

Primary outcome measure(s)
- Objective response rates (ORR) — Up to approximately 2 years
ORR is the proportion of subjects with complete response(CR) or partial response(PR) , based on RECIST v1.1
- Number of participants with adverse events (AEs) — Up to approximately 2 years
An AE is any untoward medical occurrence in a participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment.
