A Study of MRG007 Combination Therapy for Advanced Colorectal Cancer

Korábbi kezelés

• Residual toxicity ≥ Grade 2 resulting from prior anti-tumor therapy.
• Cerebrovascular accident, pulmonary embolism, or deep vein thrombosis occurring within 3 months prior to the first dose of the investigational drug; thrombosis associated with implanted venous ports or catheters; or superficial vein thrombosis, except for patients with stable thrombosis after standard anticoagulation therapy. Prophylactic use of low-dose low-molecular-weight heparin is permitted.
• History of gastrointestinal perforation and/or fistula within 6 months prior to the first dose of the investigational drug that has not healed following surgical treatment; risk of bowel obstruction or bowel perforation; extensive bowel resection; poorly controlled Crohn's disease, ulcerative colitis, or other gastrointestinal autoimmune or inflammatory diseases; presence of pyloric obstruction and/or persistent recurrent vomiting.
• Hypersensitivity to any component or excipient of MRG007, or known ≥ Grade 3 hypersensitivity to other prior anti-CDH17 antibodies or other monoclonal antibodies.

Más betegség

• Trial participants with synchronous or multiple primary malignancies.
• History of severe cardiovascular disease.
• Active chronic hepatitis B, active hepatitis C, or human immunodeficiency virus (HIV) infection.
• Body weight loss ≥ 10% during the screening period. Any severe and/or uncontrolled systemic disease that, in the opinion of the investigator and the sponsor, renders the participant unsuitable for participation in this study.

Egyéb

• Trial participants with known deficient mismatch repair/microsatellite instability-high (dMMR/MSI-H).
• Symptomatic central nervous system (CNS) metastases and/or leptomeningeal metastases.
• Clinically symptomatic moderate or larger volume pleural, ascitic, or pelvic effusions requiring clinical intervention, or clinically symptomatic pericardial effusion.

• Expected survival of ≥ 3 months.
• Tumor tissue specimens must be provided for relevant biomarker testing. If archived tissue specimens are unavailable, a new biopsy must be performed.
• Pathologically confirmed, unresectable locally advanced or metastatic colorectal adenocarcinoma.
• At least one measurable lesion according to RECIST v1.1 criteria. Measurable lesions should not have received prior radiotherapy; however, measurable lesions located within a prior radiation field or after local therapy may be selected as target lesions if disease progression is confirmed.
• Eastern Cooperative Oncology Group (ECOG) performance status score of 0 or 1
• Adequate organ function must be demonstrated.
• Sexually active males and females of childbearing potential must agree to use highly effective contraceptive measures from the time of signing the informed consent form until 6 months after the last dose of the investigational drug. Females of childbearing potential include premenopausal females and postmenopausal females within 1 year after menopause. Females of childbearing potential must have a negative serum pregnancy test result ≤ 7 days prior to the first dose and before randomization.
