简要总结
The purpose of this China extension study is to assess the safety and efficacy of coformulated favezelimab/pembrolizumab (MK-4280A) in adult Chinese participants with metastatic colorectal cancer. The study will also compare MK-4280A with the standard of care treatment of regorafenib and TAS-102 (trifluridine and tipiracil).
The primary study hypothesis is that coformulated favezelimab/pembrolizumab (MK-4280A) is superior to standard of care with respect to overall survival.
详细描述
The China extension study will include participants previously enrolled in China in the global study for MK-4280A-007 (NCT05064059) plus those enrolled during the China extension enrollment period. A total of approximately 94 Chinese participants will be enrolled.
As of Amendment 3 of the supplemental statistical analysis plan, patient reported outcomes will no longer be secondary outcome measures of the study.

- •Submits an archival (≤ 5 years) or newly obtained tumor tissue sample or newly obtained tumor tissue sample that has not been previously irradiated.
- •Has an Eastern Cooperative Oncology Group Performance Score (ECOG PS) of 0 to 1 within 10 days prior to first dose of study intervention.
- •Has a life expectancy of at least 3 months, based on the investigator assessment.
- •Has the ability to swallow and retain oral medication and not have any clinically significant gastrointestinal abnormalities that might alter absorption.
- •Has adequate organ function.
排除标准
- •Has previously been found to have deficient mismatch repair/microsatellite instability-high (dMMR/MSI-H) tumor status.
- •Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis or leptomeningeal disease.
- •Has a history of acute or chronic pancreatitis.
- •Has neuromuscular disorders associated with an elevated creatine kinase (eg, inflammatory myopathies, muscular dystrophy, amyotrophic lateral sclerosis, spinal muscular atrophy)
- •Has clinically significant cardiovascular disease within 12 months from first dose of study intervention, including New York Heart Association Class III or IV congestive heart failure, unstable angina, myocardial infarction, cerebral vascular accident, or cardiac arrhythmia associated with hemodynamic instability.
- •Has urine protein greater than or equal to 1g/24h.
- •A woman of childbearing potential who has a positive urine/serum pregnancy test within 24/72 hours prior to the first dose of study intervention.
- •Has received prior therapy with an anti-programmed cell death 1 (PD-1), anti-programmed death ligand 1 (PD-L1), or anti-programmed cell death ligand 2 (PD-L2), anti-lymphocyte activation gene 3 (LAG-3) antibody, with a tyrosine kinase inhibitor (TKI; eg, lenvatinib) other than rapidly accelerated fibrosarcoma (RAF) inhibitors (binimetinib is permitted if combined with a RAF inhibitor), or with an agent directed to another stimulatory or coinhibitory T-cell receptor (eg, cytotoxic T-lymphocyte-associated protein 4, OX-40, cluster of differentiation [CD] 137).

- •Has known history of Hepatitis B or known active Hepatitis C virus infection.
- •Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the study, interfere with the participant's participation for the full duration of the study, or is not in the best interest of the participant to participate, in the opinion of the treating investigator.
- •Has had an allogenic tissue/solid organ transplant.
