Aravive, Inc. announced that the Company has received guidance from the U.S. Food and Drug Administration (FDA) on a registrational Phase 3 trial design for batiraxcept in clear cell renal cell carcinoma (ccRCC) at an End-of-Phase 2 (EOP2) meeting. The randomized, double-blind, registrational Phase 3 trial is designed to evaluate efficacy and tolerability of batiraxcept at a dose of 15 mg/kg in combination with cabozantinib compared to cabozantinib alone. The trial is expected to enroll approximately 300 patients with histologically confirmed advanced or metastatic ccRCC who have progressed after one or two prior lines of systemic therapy, which include immuno-oncology (IO)-based and vascular endothelial growth factor tyrosine kinase inhibitor (VEGF-TKI)-based therapies (either in combination or sequentially).

Patients who were previously treated with cabozantinib are excluded from the trial. This ccRCC population was chosen based upon results from Phase 1/2 trial which demonstrated a benefit in both median PFS and ORR with the addition of batiraxcept to cabozantinib in patients who had failed prior IO and VEGF-TKI treatments. The global trial is planned to be conducted at approximately 100 sites in the U.S. and around the world.

The primary endpoint is progression-free survival, and secondary endpoints include overall survival, duration of response, and objective response rates. Batiraxcept was granted Fast Track Designation by the FDA for ccRCC in November 2022.
