Biocytogen Pharmaceuticals (Beijing) Co., Ltd. ("Biocytogen") and TRACON Pharmaceuticals, Inc. (Nasdaq: TCON), today jointly announced that the U.S. Food and Drug Administration (FDA) has approved the Investigational New Drug (IND) application for the initiation of a Phase 1/2 clinical study of YH001 in combination with envafolimab and doxorubicin for the treatment of sarcoma patients, including patients who have not received prior therapy.

The Phase 1/2 trial will assess the safety and efficacy of YH001 and envafolimab in patients with the rare sarcoma subtypes of alveolar soft part sarcoma and chondrosarcoma and assess the safety and efficacy of the combination of YH001, envafolimab and doxorubicin in the common sarcoma subtypes of leiomyosarcoma and dedifferentiated liposarcoma.

“YH001 was discovered using Biocytogen’s evidence-based in vivo drug efficacy screening platform and has demonstrated a favorable safety profile and promising anti-tumor activity in combination with a PD-1 antibody in an earlier phase 1 clinical study,” said Rong Chen, M.D., Ph.D., VP of Biocytogen, CEO and CMO of Eucure Biopharma. “As an antibody targeting the validated checkpoint CTLA-4, YH001 is expected to play a very important role in immune-oncology therapy. We are glad to learn that the combination therapy of YH001 + envafolimab and doxorubicin received IND approval by the FDA.”

“We are pleased to receive approval from the FDA to initiate our triplet combination therapy study in sarcoma, which includes our potentially best-in-class CTLA-4 antibody YH001 and the only subcutaneous checkpoint inhibitor approved anywhere in the world, envafolimab,” said Charles Theuer, M.D., Ph.D., TRACON’s Chief Executive Officer. “We look forward to enrolling patients in this study and giving patients additional options for their sarcoma treatment.”

About YH001
YH001 is an IgG1 antibody targeting CTLA-4 that was invented by Biocytogen, the parent company of Eucure Biopharma, and licensed by TRACON. YH001 has shown enhanced antibody dependent cellular cytotoxicity (ADCC) and complement dependent cytotoxicity (CDC) in vitro when compared with ipilimumab. In preclinical studies YH001 demonstrated superior T cell activation and superior tumor growth inhibition activity compared to ipilimumab as a single agent and when combined with a PD-(L)1 antibody in human transgenic mouse tumor models. In these models, single agent YH001 depleted regulatory T cells and increased CD8+ T cells in tumor tissue. YH001 has been dosed as a single agent in a Phase 1 trial in China (NCT04699929) and in combination with the PD-1 antibody toripalimab in a Phase 1 trial in Australia (NCT04357756).
