Clinical Trial Summary

The aim of this study is to assess the safety, side effects and effectiveness of EP0031 in patients with advanced RET-altered malignancies

Description:

EP0031 is being investigated in this modular, interventional Phase I/II dose escalation and dose expansion study to investigate the optimal dose in adult patients with advanced RET-altered malignancies. Currently there are no approved RET-targeted treatments for patients who progress on first-generation SRIs. However, it is proposed that EP0031 can overcome resistance mechanisms to first generation SRIs, as EP0031 is a potent and selective RET inhibitor with broad activity against common RET fusions and mutations.
