HOUSTON, May 12, 2022 (GLOBE NEWSWIRE) -- Aravive, Inc. ARAV "the Company"))), a late clinical-stage oncology company developing targeted therapeutics to treat metastatic disease, today reported financial results for the first quarter ended March 31, 2022 and provided corporate updates.

"During the first quarter we continued to advance the development of batiraxcept for the potential treatment of ovarian, kidney and pancreatic cancer, successfully raised additional capital and strengthened the management team," said Gail McIntyre, Ph.D., DABT, Chief Executive Officer of Aravive. "Our registrational Phase 3 trial of batiraxcept in ovarian cancer continues on pace to complete enrollment in 2022, with top line data anticipated in 2Q'23 and a potential BLA filing with the FDA in 4Q'23. Our ongoing Phase 2 trial of batiraxcept in clear cell renal cell carcinoma also continues to successfully enroll patients across three cohorts and the Phase 1b trial of batiraxcept in pancreatic cancer completed enrollment in 1Q'22. Updated results are anticipated throughout 2022. We remain encouraged by the continued signals of best-in-class potential of batiraxcept and look forward to providing continued clinical updates on each of our three active programs throughout 2022."

Recent Corporate Highlights

• Batiraxcept in Platinum Resistant Ovarian Cancer (PROC): The registration-directed Phase 3 program of batiraxcept in combination with paclitaxel in PROC remains on track to complete enrollment in 2H'22. Topline data from the trial is anticipated to be available in 2Q'23. CMC work related to the PROC program remains on track with the goal of filing a BLA in 4Q'23. The global, randomized, double-blind, placebo-controlled Phase 3 trial is evaluating efficacy and tolerability of batiraxcept at a dose of 15 mg/kg in combination with paclitaxel versus placebo in combination with paclitaxel. The trial aims to enroll 350 platinum resistant, high-grade serous ovarian cancer patients who have received 1-4 prior lines of therapy.
  
  
• Batiraxcept in Clear Cell Renal Cell Carcinoma (ccRCC) and Serum-Based Biomarker: The Company dosed first patient in the Phase 2 study of batiraxcept in combination with cabozantinib in 2L+ ccRCC trial in January 2022. Enrollment across the three patient cohorts of the Phase 2 study continues on pace for planned completion and updated data releases during 2Q'22. The Company anticipates providing clinical updates on the Phase 2 study throughout 2022. In March 2022, the Company announced new biomarker data from the Phase 1b portion of the trial in patients with ccRCC. Aravive had previously reported an observable correlation of baseline levels of serum soluble AXL (sAXL)/GAS6 to clinical activity in its Phase 1b PROC trial. As such, one of the objectives of the ongoing Phase 1b/2 ccRCC trial is to evaluate the correlation of baseline sAXL/GAS6 with radiographic response in patients with ccRCC treated with batiraxcept plus cabozantinib. The Company continues to engage the US FDA about utilizing the biomarker as a basis for an accelerated development strategy. Updated biomarker data is anticipated in 2022.
  
  As of April 30, 2022, 26 patients with ccRCC were treated with batiraxcept in the Phase 1b portion of the trial at doses of 15 mg/kg (n=16) and 20 mg/kg (n=10), plus cabozantinib 60 mg daily in previously treated (2L+) patients with ccRCC. There were no dose limiting toxicities observed at either dose and 14 of the 26 patients remain on study. The best overall response rate (ORR, confirmed + unconfirmed) in the ITT population was 46% and 50% in patients dosed with 15 mg/kg (the recommended Phase 2 dose). The best ORR in the biomarker high population was 60%, and 67% in the biomarker high population dosed at 15 mg/kg. The 7-month progression-free survival (PFS) rate was 71% in the ITT population, 83% in the biomarker high population, and 91% in the 15 mg/kg biomarker high group. Eight patients experienced resolution of one or more target lesions. The company is on track to report additional updated results from the Phase 1b portion of the trial in the second quarter of 2022.
  
  
• Batiraxcept in Pancreatic Adenocarcinoma: In January 2022, Aravive completed enrollment of the Phase 1b portion of its Phase 1b/2 trial of batiraxcept in combination with gemcitabine and nab-paclitaxel as a first-line treatment in patients with advanced or metastatic pancreatic adenocarcinoma who are eligible to receive gemcitabine and nab-paclitaxel combination therapy. As of May 3, 2022, 21 patients have been treated with 15 mg/kg batiraxcept in combination with gemcitabine and nab-paclitaxel as a first-line treatment. Batiraxcept has been generally well-tolerated with no unexpected safety signals. The best ORR (confirmed + unconfirmed) was 29%. As noted with the other programs, an observable correlation of baseline levels of serum soluble AXL (sAXL)/GAS6 to clinical activity was noted in this trial as well and the best ORR in the biomarker high population was 40%. Five patients experienced resolution of one or more target lesions; however, 2 of these patients have since progressed. The company is on track to report additional updated data from the Phase 1b portion of the trial in the second quarter of 2022.
• Strengthened Balance Sheet: In January 2022, Aravive raised approximately $10.0 million from the sale of a pre-funded warrant to purchase 4,545,455 shares of the company's common stock to Eshelman Ventures, LLC at a price of $2.20 per share, which was the consolidated closing bid price of the company's common stock on The Nasdaq Global Select Market on December 31, 2021. Additionally, Fred Eshelman, Pharm.D., was appointed the Executive Chairman of Aravive, having served as the Non-Executive Chairman of the board since April 2020. In March 2022, the Company raised an additional approximately $10.0 million from the sale of common stock and a pre-funded warrant for an aggregate of a combination of 4,850,241 shares of the company's common stock and pre-funded warrants to a single healthcare-focused institutional investor and Eshelman Ventures, LLC and issued warrants to purchase an additional aggregate of 4,850,241 shares of common stock in a registered direct offering priced at-the-market under Nasdaq rules. Combined, the additional capital infusions strengthen the Company's financial position and fund operations as currently planned into 1Q'23.
