3 of 5 (60%) patients achieved a partial response
All 5 patients treated demonstrated tumor decrease from baseline
Batiraxcept has been generally well-tolerated with no dose-limiting toxicities
Aravive to host conference call and webcast on November 12 at 8:30 a.m. ET to discuss updated data
HOUSTON, Nov. 09, 2021 (GLOBE NEWSWIRE) -- Aravive, Inc. (Nasdaq: ARAV), a clinical-stage oncology company developing transformative, targeted therapeutics to treat life-threatening cancers, today announced that positive new data from the Phase 1b portion of its open-label Phase 1b/2 trial evaluating batiraxcept (AVB-500) in combination with cabozantinib in patients with clear cell renal cell carcinoma (ccRCC) will be presented at the Society for Immunotherapy of Cancer’s (SITC) 36th Annual Meeting on November 13, 2021. The presentation will highlight interim safety, pharmacokinetic (PK), pharmacodynamic (PD), and clinical activity data.
“We are encouraged by the preliminary performance of batiraxcept in combination with cabozantinib in patients with clear cell renal cell carcinoma,” said Gail McIntyre, Ph.D., DABT, Chief Executive Officer of Aravive. “These results highlight the potential of batiraxcept to improve outcomes for patients with advanced kidney cancer. We look forward to sharing these new clinical data with the research and medical community at this year’s SITC Annual Meeting.”
As of July 21, 2021, seven patients received at least one dose of batiraxcept 15 mg/kg in combination with cabozantinib, six patients were ongoing treatment, and five patients were evaluable for efficacy. No dose-limiting toxicities were observed. Trough levels at cycle 1 day 15 were above the minimal efficacious concentration identified from the Company’s model informed drug development approach, and serum GAS6 levels were suppressed prior to cycle 2 day 1. A best overall response of partial response was observed in 3 of 5 patients (60%, unconfirmed as of July 21, 2021), based on investigator assessment, RECIST v 1.1 criteria. In addition, all patients demonstrated tumor decrease from baseline.
Aravive’s presentation at the SITC Annual Meeting will include updated safety, PK, PD, and clinical activity data from a larger set of patients treated with batiraxcept 15 mg/kg in combination with cabozantinib as of October 16, 2021.

About the Batiraxcept (AVB-500) Phase 1b/2 ccRCC Trial
Aravive initiated the Phase 1b portion of the Phase 1b/2 trial of batiraxcept in ccRCC in March 2021. The Phase 1b portion of the clinical trial, a dose escalation study, is expected to enroll approximately 18 patients in three dosing arms (15 mg/kg, 20 mg/kg and 25 mg/kg) to evaluate tolerability, pharmacokinetics, pharmacodynamics, and clinical activity of batiraxcept in combination with cabozantinib. The controlled, randomized, open-label Phase 2 portion of the clinical trial is expected to enroll approximately 45 patients and investigate the recommended batiraxcept dose identified during the Phase 1b portion of the clinical trial in combination with cabozantinib versus cabozantinib alone. The primary endpoint is progression-free survival. The trial is enrolling patients with advanced ccRCC who have progressed on front-line treatment. The Phase 1b/2 trial is listed on clinicaltrials.gov NCT04300140.
About Batiraxcept (AVB-500)
Batiraxcept is a therapeutic recombinant fusion protein that has been shown to neutralize GAS6 activity by binding to GAS6 with very high affinity in preclinical models. In doing so, batiraxcept selectively inhibits the GAS6-AXL signaling pathway, which is upregulated in multiple cancer types including ovarian, renal and pancreatic cancer. In preclinical studies, GAS6-AXL inhibition has shown anti-tumor activity in combination with a variety of anticancer therapies, including radiation therapy, immuno-oncology agents, and chemotherapeutic drugs that affect DNA replication and repair. Increased expression of AXL and GAS6 in tumors has been correlated with poor prognosis and decreased survival and has been implicated in therapeutic resistance to conventional chemotherapeutics and targeted therapies. Batiraxcept is currently being evaluated in multiple clinical trials and has been granted Fast Track designation by the U.S. Food and Drug Administration and orphan drug designation by the European Commission in platinum resistant recurrent ovarian cancer.
