Treatments tested in this trial
YL242
DrugThe YL242 drug product is provided as a lyophilized powder containing 200 mg of YL242 in a glass vial. The initial dose of YL242 will be infused IV into each patient for 90±10 minutes. If there is no infusion-related reaction after the initial dose, the second and subsequent doses of YL242 will be infused IV into each patient for 60±10 minutes.
YL242; Pembrolizumab
DrugThe YL242 drug product is provided as a lyophilized powder containing 200 mg of YL242 in a glass vial. The initial dose of YL242 will be infused IV into each patient for 90±10 minutes. If there is no infusion-related reaction after the initial dose, the second and subsequent doses of YL242 will be infused IV into each patient for 60±10 minutes. Pembrolizumab will be administered subsequent to YL242.
YL242; 5-FU; LV
DrugThe YL242 drug product is provided as a lyophilized powder containing 200 mg of YL242 in a glass vial. The initial dose of YL242 will be infused IV into each patient for 90±10 minutes. If there is no infusion-related reaction after the initial dose, the second and subsequent doses of YL242 will be infused IV into each patient for 60±10 minutes. LV and 5-FU will be sequentially administered following YL242.
YL242; Pembrolizumab; 5-FU
DrugThe YL242 drug product is provided as a lyophilized powder containing 200 mg of YL242 in a glass vial. YL242 will be administered via Intravenous (IV) Infusion. Pembrolizumab and 5-FU will be administered in sequence after YL242.
Treatment groups
Trial outcomes
Primary outcomes
Objective Response Rate (ORR) in Participants With Advanced Solid Malignant Tumors (Part 2, and 4-6)
Objective response rate (ORR) was defined as the proportion of participants who achieve either complete response \[CR\] or partial response \[PR\] per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1.
Number of Participants Reporting Treatment-emergent Adverse Events (TEAEs)
AEs will be collected systematically from signing of the informed consent form (ICF) through 42 days after last dose.
Secondary outcomes
Area Under the Serum Concentration Time Curve (AUC) of YL242
Maximum Plasma Concentration (Cmax) of YL242
Time to Maximum Plasma Concentration (Tmax) of YL242
Incidence of anti-YL242 antibody
