CRC Oncology announced today the dosing of the first patient in a phase I first-in-human clinical trial of TransThera Biosciences Co., Ltd.’s lead product candidate, TT-00420, for the treatment of triple negative breast cancer (TNBC) and advanced solid tumors.

“We are excited to announce the initiation of this first-in-human clinical trial with TransThera following the successful filing of our first US IND submission in September, which have been incredible milestone achievements for CRC” stated Dr. Qinhua Cindy Ru, founder and managing director of CRC Oncology. “We are honored to have worked with TransThera on this project, which has helped our company establish our platform in regulatory and clinical development, and we look forward to collaborating on future projects to come.”

Dr. Frank Wu, founder and CEO of TransThera, stated, “we are excited to assess TT-00420’s therapeutic potential observed from pre-clinical studies in this phase I clinical trial, and we hope that TT-00420 can transform the treatment landscape for TNBC.”

The phase I study is a global, multicenter trial to evaluate the safety, tolerability, and efficacy of TT-00420. The trial will enroll approximately 70 patients with locally advanced or metastatic TNBC or other solid tumors with no available standard therapeutic treatment options. Patients will be treated with a single oral administration of TT-00420 daily on a continuous schedule.
