TRACON Pharmaceuticals Announces Submission of IND Application for CTLA-4 Antibody YH001 for the Treatment of Front-line Sarcoma Patients in Combination with Envafolimab
The Phase 1/2 trial will assess the safety and efficacy of YH001 and envafolimab with or without doxorubicin in patients with the rare sarcoma subtypes of alveolar soft part sarcoma and chondrosarcoma and in the common sarcoma subtypes of leiomyosarcoma and dedifferentiated liposarcoma.
“With the submission of the IND, we are one step closer to bringing our triple combination of YH001, envafolimab and doxorubicin to front-line sarcoma patients, and pending clearance of the IND, we look forward to initiating the trial before end of this year,” said
YH001, an IgG1 antibody against CTLA-4 invented by Biocytogen, the parent company of Eucure Biopharma, and licensed by TRACON, has shown enhanced antibody dependent cellular cytotoxicity (ADCC) and complement dependent cytotoxicity (
About the Phase 1/2 Clinical Trial of YH001, envafolimab and doxorubicin (NCT05448820)
The Phase 1/2 clinical trial is a multicenter, open label study of YH001 initially given in combination with envafolimab, and then given in combination with envafolimab plus doxorubicin in patients with advanced or metastatic sarcoma, followed by Phase 2 cohorts of patients with select histologies of advanced or metastatic sarcoma, including treatment naive patients. The primary objective of the Phase 1 portion of the trial is to determine the recommended phase 2 dose of YH001 in combination with envafolimab and in combination with envafolimab with doxorubicin. The primary objective of the Phase 2 portion is to determine the objective response rate (ORR) of the combination of YH001 and envafolimab in patients with alveolar soft part sarcoma and chondrosarcoma and the ORR of the combination of YH001, envafolimab and doxorubicin in patients with leiomyosarcoma and dedifferentiated liposarcoma.
Envafolimab (KN035), a single-domain antibody against PD-L1 invented by Alphamab Oncology and licensed by TRACON, is the first approved subcutaneously injected PD-(L)1 inhibitor. Envafolimab was approved by the Chinese NMPA in
