Experiment 1 Reporting the Activity Date of This ADC [1]
Patients Enrolled
Eligible patients must have advanced solid tumors (RECIST 1.1 measurable), ECOG 0-1, and adequate organ function. Key exclusions include active inflammatory bowel disease, uncontrolled cardiovascular/CNS conditions, recent anticancer therapies (within 2-4 weeks), active HBV/HCV/HIV co-infections (unless controlled), or symptomatic effusions requiring drainage.

Administration Dosage
Participants receive MK-3120 at dose level 1/2 as per the schedule specified in the arm.
Related Clinical Trial
NCT Number NCT06818643  Clinical Status PHASE1|||PHASE2
Clinical Description A Phase 1/2 Open-label Study to Evaluate the Safety and Efficacy of MK-3120 in Participants With Advanced Solid Tumors
Primary Endpoint
The primary safety outcomes include incidence of adverse events (AEs) and treatment discontinuations due to AEs over ~30 months, capturing all medically significant occurrences regardless of causality.
Other Endpoint
Efficacy measures assess objective response rate (ORR), duration of response (DOR), progression-free survival (PFS), and overall survival (OS) per RECIST 1.1 over ~34 months, alongside pharmacokinetic parameters (AUC, Cmin, Cmax) of MK-3120 monitored for ~4 months.
Experiment 2 Reporting the Activity Date of This ADC [2]
Patients Enrolled
Eligible participants must be ≥18 years with advanced solid tumors (RECIST v1.1 measurable), ECOG 0-1, and adequate organ function. Key exclusions include recent anti-tumor therapies (within 4 weeks/5 half-lives), active CNS metastases, uncontrolled cardiovascular/autoimmune diseases, HIV/active hepatitis infections, pregnancy/lactation, or prior stem cell/organ transplantation.

Administration Dosage
SKB410 for injection is administered every 2 weeks (q2w) until radiographic disease progression (PD), intolerable toxicity, death, or discontinuation of treatment, whichever occurs first.

NCT Number NCT05906537  Clinical Status PHASE1
Clinical Description A Phase I Clinical Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Preliminary Efficacy of SKB410 for Injection in Subjects with Advanced Solid Tumors
Primary Endpoint
Phase Ia evaluates dose-limiting toxicities (DLTs) and maximum tolerated dose (MTD) within 28 days post-treatment initiation, while Phase Ib assesses objective response rate (ORR) per RECIST v1.1 over approximately 2 years.
