61The objective of this study is to assess the safety, efficacy, and pharmacokinetics of MRG003, as well as immunogenicity as defined by the incidence of anti-drug antibody (ADA) of MRG003 in patients with advanced solid tumors, including colorectal cancer, squamous cell carcinoma of head and neck, and nasopharyngeal carcinoma.
This study consists of two parts: Phase Ia dose escalation and Phase Ib dose expansion. The objective of Phase Ia is to determine MTD or RP2D, and Phase Ib is conducted to evaluate efficacy of MRG003 in patients with advanced colorectal cancer, squamous cell carcinoma of head and neck (SCCHN), and nasopharyngeal carcinoma.
Phase Ia: MRG003 will be administrated by an IV infusion of escalating doses (0.1, 0.3, 0.6, 1.0, 2.0, 2.5, 3.0 mg/kg) on Day 1 of every 3 weeks (Q3W); Phase Ib: MRG003 will be administrated by an IV infusion of MTD/RP2D.
Inclusion Criteria: Willing to sign the ICF and follow the requirements specified in the protocol. Age: ≥18 years and ≤75 years, both genders Expected survival time≥12 weeks Phase Ia: Patients with histologically and cytologically confirmed advanced or metastatic solid tumor Phase Ib: Patients with histologically and cytologically confirmed EGFR-positive advanced or metastatic colorectal cancer, squamous cell carcinoma of head and neck, and nasopharyngeal carcinoma Subjects must have measurable lesions according to the response Evaluation Criteria In Solid Tumors（RECIST v1.1） ECOG performance score 0 or 1 Acceptable liver, renal, and hematologic function Patients with childbearing potential must use effective contraception during the treatment and for 6 months after the last dose of treatment Exclusion Criteria: History of hypersensitivity to any component of the investigational product Presence of central nervous system metastasis Prior history of other primary malignancies Known history of clinically significant hepatic diseases Evidence of active infection of human immunodeficiency virus (HIV) History of ophthalmic abnormalities Any severe or uncontrolled systemic disease judged by the investigator Patients with poorly controlled heart diseases Received radiotherapy, chemotherapy, biotherapy, immunotherapy or other anti-tumor drugs within 4 weeks prior to the first dose of study treatment Major surgery or surgical therapy for any cause within 4 weeks prior to the first dose of investigational drug Planned surgery or surgery is the best interest of patients as determined by investigator History of severe skin disease requiring interruption of previous EGFR targeted therapy; or chronic skin disease requiring oral or intravenous therapy Active concomitant diseases that might increase risks of toxicity Pregnancy, or breast feeding
