Descrizione dettagliata

YL217 is an antibody-drug conjugate (ADC) that targets CDH17 (Cadherin-17) protein and is being developed for the treatment of cancer. YL217 is comprised of three components: 1) YL217-mAb, a CDH17-targeting recombinant humanized immunoglobulin G1 (IgG1) monoclonal antibody, 2) YL0010014, a topoisomerase I inhibitor, and 3) an enzymatically cleavable methylsulfonyl pyrimidine tripeptide drug linker.

The in vivo anti-tumor efficacy of YL217 was evaluated in immune-deficient mice bearing human colorectal cancer, gastric cancer and patient derived colorectal cancer xenograft tumors. The results indicated that YL217 was well tolerated, and YL217 suppressed growth of established human tumors in a dose-dependent manner in cancer cells or patient derived xenograft models.

Therefore, in order to meet the huge unmet medical needs in the field of gastrointestinal cancer treatment, it is planned to conduct the first human phase I clinical study of YL217 in patients with advanced solid tumors.
