Aravive Announces First Patient Dosed In Phase 2 Study Of Batiraxcept In Clear Cell Renal Cell Carcinoma

Aravive, Inc. (NASDAQ:ARAV), a late clinical-stage oncology company developing targeted therapeutics to treat metastatic disease, today announced that the Company has dosed the first patient in the Phase 2 portion of the Phase 1b/2 study of batiraxcept for the treatment of clear cell renal cell carcinoma (ccRCC).

"Safety and preliminary activity data from the Phase 1b study of batiraxcept in combination with cabozantinib in patients with 2L+ ccRCC gives us confidence to initiate the Phase 2 portion of the trial and expand the study to additional cohorts," said Gail McIntyre, Ph.D., DABT, Chief Executive Officer of Aravive. "I'm grateful to our team for their diligence and dedication to expedite the ccRCC program. The data reported to date shows clinically relevant benefit of adding batiraxcept to the current standard of care in ccRCC without adding to the toxicity profile. We will continue to update the ongoing Phase 1b portion of the study as data mature and anticipate providing clinical activity and safety updates of the P2 portion of the study throughout 2022."

The Phase 2 portion of the Phase 1b/2 clinical trial of batiraxcept in ccRCC is an open-label study in which 55 patients are anticipated to enroll across three parts. Part A is expected to enroll approximately 25 patients and will investigate batiraxcept 15 mg/kg in combination with cabozantinib in 2L+ ccRCC patients. Part B is expected to enroll approximately 20 patients and evaluate batiraxcept 15 mg/kg in combination with standard of care nivolumab and cabozantinib in first-line ccRCC patients. Part C is expected to evaluate batiraxcept 15 mg/kg monotherapy in approximately 10 patients with ccRCC who are not eligible for curative intent therapies. The primary endpoint of each part of the Phase 2 portion of the trial is objective response rate ("ORR") and key secondary endpoints include duration of response ("DOR"), progression free survival ("PFS"), and overall survival ("OS").
