HOUSTON, Aug. 02, 2023 (GLOBE NEWSWIRE) -- Aravive, Inc. (Nasdaq: ARAV, “the Company”), a late clinical-stage oncology company developing targeted therapeutics to treat metastatic disease, today announced that its Phase 3 AXLerate-OC trial evaluating the safety and efficacy of batiraxcept in platinum-resistant ovarian cancer did not meet its primary endpoint of progression-free survival (PFS) in the pre-specified subset of patients naïve to prior bevacizumab treatment. The trial did not show any difference between the two arms in the overall population (which included patients previously treated with bevacizumab). The Company will continue to evaluate the complete dataset and determine next steps in the development of batiraxcept.

“We are conducting additional analyses on the AXLerate-OC Phase 3 trial to further evaluate the results of this study and determine the best path forward with our two other planned indications in renal cell carcinoma and pancreatic cancer,” said Gail McIntyre, Ph.D., DABT, Aravive’s President and Chief Executive Officer. “We want to thank the patients who participated in this trial, the clinical investigators, and the Aravive team for their hard work, as we continue to pursue our goal of finding innovative cancer treatments for patients in need.”

Key Findings from AXLerate-OC Study 
AXLerate-OC enrolled 366 patients, and randomization was stratified for prior bevacizumab treatment; 50% of patients received bevacizumab prior to study entry. The statistical analysis plan called for a hierarchical approach for the assessment of PFS first in the bevacizumab-naïve population and then in the overall cohort of patients. In the bevacizumab-naïve population (n=179), the median PFS in the batiraxcept plus paclitaxel arm was 5.4 months, compared to 5.4 months in the paclitaxel arm. In the overall population, the median PFS in the batiraxcept plus paclitaxel arm was 5.1 months, compared to 5.5 months in the paclitaxel arm. None of these differences were statistically different.

The safety profile of batiraxcept was as expected from previous studies. No new safety signals were identified.

“Although AXLerate-OC did not meet the primary endpoint, I look forward to working with Aravive to analyze the Phase 3 data and determine the most appropriate path to bring batiraxcept to those patients who may benefit most,” said Dr. Katherine Fuh, Associate Professor, UCSF Division of Gynecologic Oncology.

About the Phase 3 PROC Trial

The global, randomized, double-blind, placebo-controlled adaptive trial (GOG-3059/ENGOT OV-66) is designed to evaluate efficacy and safety of batiraxcept at a dose of 15 mg/kg in combination with paclitaxel. The trial enrolled 366 patients with high-grade serous ovarian cancer who have received one to four prior lines of therapy at approximately 165 sites in the U.S. and Europe. The primary endpoint for the trial is progression free survival and the secondary endpoint is overall survival. Exploratory endpoints include objective response rate, duration of response, quality of life, clinical benefit rate, pharmacokinetic and pharmacodynamic profile, and sAXL/GAS6 ratio. This trial was conducted in partnership with The GOG Foundation, Inc. (GOG-F), through the GOG Partners program in the USA and in partnership with the European Network for Gynecological Oncological Trial (ENGOT) groups in Europe. The Phase 3 trial is listed on clinicaltrials.gov NCT04729608.
