GenSci139 in Patients With Advanced Solid Tumors

Recruiting now · Phase 1

Conditions studied: Advanced Solid Tumors

In brief

This is a phase I, two-part, multicenter, first-in-human study. The Part 1 study will assess the safety, tolerability, preliminary anti-tumor activities, PK profile, immunogenicity and biomarker of GenSci139 in participants with locally advanced or metastatic solid tumors, as well as identity MTD (if any) and RDE. The Part 2 study is to further evaluate the preliminary anti-tumor activities, safety, PK profile, immunogenicity and biomarker of GenSci139 at RDE dose levels with selected advanced cancers.

• Nonsterile males must be willing to use adequate contraception for the duration of receiving GenSci139 and within 6 months after the last dose of GenSci139.
• Has histologically or cytologically confirmed locally advanced or metastatic UC, HNSCC, TNBC, NSCLC, BTC, ESCC, GC, CRC, OC, NPC, PDAC etc. and have progressed following standard therapy, or for whom, in the opinion of the investigator, no available and effective standard therapy exists.
• Key Exclusion Criteria:
• Any active malignancy within 3 years before initiation dose of GenSci139 except for the cancer under investigation in this study and any locally recurring cancer that has been treated curatively (e.g., resected basal or squamous cell skin cancer, non-muscle invasive bladder cancer (NMIBC), carcinoma in situ of the cervix or breast).
• Has diagnosed as primary central nervous system (CNS) tumor.
• Has CNS metastases, unless asymptomatic, neurologically stable and not requiring steroids treatment for at least 4 weeks prior to initiation dose of GenSci139.
