Experimental: Dose-Escalation Stage
Participants will be assigned sequentially to escalating doses of BLYG8824A, up to the maximum tolerated dose (MTD).
|
Drug: BLYG8824A
BLYG8824A will be administered at a flat dose independent of body weight. |
Experimental: Dose-Expansion Stage
Once dose escalation is completed and the MTD (or MAD) has been identified, a recommended expansion dose will be proposed for the dose-expansion stage of the trial.
|
Drug: BLYG8824A
BLYG8824A will be administered at a flat dose independent of body weight. |

- Overall Response Rate (ORR) [ Time Frame: Approximately 48 months ]ORR is defined as the proportion of patients with a complete response (CR) or partial response (PR) as determined by the investigator according to Response Evaluation Criteria in Solid Tumors, Version 1.1 (RECIST v1.1)
- Duration of Response (DOR) [ Time Frame: Approximately 48 months ]Duration of response (DOR), defined as the time from the first occurrence of a documented objective response to disease progression or death from any cause (whichever occurs first), as determined by the investigator according to RECIST v1.1
- Presence of Anti-drug Antibodies (ADAs) [ Time Frame: Cycle 1, Day 1; Cycle 2 Day 1; Cycles ≥ 3, Day 1; Treatment Completion/ Discontinuation (Cycle length: 21 days) ]

- Progression must have occurred during or after most recent treatment for locally advanced or metastatic colorectal cancer
- For patients enrolled in either a dedicated biopsy cohort or other expansion cohorts where biopsy is clinically feasible, willingness to consent to mandatory fresh pretreatment and on-treatment biopsies of safely accessible tumor lesions
Exclusion Criteria:
