Conditions
Advanced Solid Tumors

Registration Number
NCT07230977
Lead Sponsor
Changchun GeneScience Pharmaceutical Co., Ltd.
Brief Summary

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.

  • Women of childbearing potential (WOCBP) must be willing to use adequate contraception while receiving GenSci139, and within 6 months after the last dose of GenSci139 and have a negative serum human chorionic gonadotropin (HCG) test.
  • 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.
