What this Trial Is About

CHANCES-IPC 2021-008 is First In Human, Phase I, multicenter, European study evaluating an anti-CD73, IPH5301 in advanced and/or metastatic cancer. The trial will be conducted in two parts, Part I- Dose escalation: This part aims to identify the maximum tolerated dose (MTD) of IPH5301 agent in monotherapy and recommended phase 2 dose (RP2D) for future trials, followed by a safety expansion study part cohort. Part II- Expansion cohort: A total of 12 HER2-expressing breast cancer patients is planned to be enrolled into the next expansion cohort to select a recommended dose of IPH5301 to be administered in combination with chemotherapy and trastuzumab for evaluation in future trials with selected advanced solid tumors.
