Recent Corporate Highlights

• The Phase 3 AXLerate-OC Trial in PROC Completed Enrollment
  The registration-directed Phase 3 trial of batiraxcept plus paclitaxel for PROC completed enrollment in January 2023. The trial planned to enroll 350 patients with platinum resistant, high-grade serous ovarian cancer who have received 1-4 prior lines of therapy. CMC work remains on track and the Company expects to report topline data from the trial by mid-2023. If those results are positive, the Company plans on submitting a Biologics License Application (BLA) to FDA by year-end 2023. The global, randomized, double-blind, placebo-controlled Phase 3 trial is evaluating efficacy and tolerability of 15 mg/kg batiraxcept in combination with paclitaxel versus placebo in combination with paclitaxel.

• Advancement of PROC trial in China Results in Milestone Payment
  The Company’s partner in China, 3D Medicines enrolled patients into the Phase 3 PROC trial, which effectively begins their Phase 3 clinical activity towards their goal of ultimate approval in China. The Company received the $6 million payment related to achievement of this milestone in October 2022, the third milestone payment received since the Company entered into an agreement with 3D Medicines in November 2020.

• Batiraxcept Granted Fast Track Designation for ccRCC Program
  In November 2022, FDA granted Fast Track designation to batiraxcept for treatment of patients with advanced or metastatic ccRCC who have progressed after 1 or 2 prior lines of systemic therapy that include both IO-based and VEGF-TKI-based therapies (either in combination or sequentially). FDA’s designation was based on new Phase 1b data showing an Objective Response Rate (ORR) of 57% and median Progression-Free Survival (PFS) of 11.4 months in patients with advanced or metastatic ccRCC who have progressed after 1 or 2 prior lines of immuno-oncology (IO)- and vascular endothelial growth factor tyrosine kinase inhibitor (VEGF-TKI)-based therapies.

• Updated ccRCC Data Presented at the 2023 ASCO Genitourinary (GU) Cancers Symposium
  The Company presented a poster at the 2023 ASCO GU Cancers Symposium in February 2023 featuring updated results from its ongoing Phase 1b/2 trial of batiraxcept in ccRCC. As of January 17, 2023, safety, pharmacokinetics (PK), pharmacodynamics (PD), and clinical activity of 15 mg/kg and 20 mg/kg batiraxcept in combination with 60 mg cabozantinib were evaluated in 26 patients with 2L+ ccRCC. In addition, one of the objectives of the ongoing Phase 1b/2 ccRCC trial is to evaluate the correlation of baseline serum soluble AXL (sAXL)/GAS6 (biomarker) with radiographic response in patients with ccRCC treated with batiraxcept plus cabozantinib. There were no dose limiting toxicities observed at either dose of batiraxcept. The best response of partial response was observed in 42% (11/26) of the overall population 57% (8/14) of the prior VEGF-TKI-treated group and 55% (11/20) of the biomarker high (sAXL/GAS6) group. The 9-month progression-free survival (PFS) rate was 65% in the overall population, 69% in the biomarker high group (n=20) and 75% in the prior VEGF-TKI, biomarker high group (n=11). Eighty-five percent of patients (22/26) had a reduction in target lesions at the 8-week response assessment, and 58% (15/26) of the total population achieved a better response on batiraxcept plus cabozantinib than they did on prior therapy. The Company has discussed a registrational path with the US FDA that includes use of the sAXL/GAS6 ratio as a potential basis for an accelerated approval.

  The open-label Phase 2 portion of the clinical trial initiated January 31, 2022 and is expected to enroll 55 patients across three parts. Part A is expected to enroll approximately 25 patients and investigate 15 mg/kg batiraxcept in combination with cabozantinib in 2L+ ccRCC patients. Part B is expected to enroll approximately 20 patients and evaluate 15 mg/kg batiraxcept in combination with nivolumab and cabozantinib as a potential front-line treatment for ccRCC. Part C is expected to evaluate 15 mg/kg batiraxcept monotherapy in approximately 10 patients with ccRCC who are not eligible for curative intent therapies.

  The Company expects to report additional data from the P1b portion and preliminary data from the P2 portion of the ccRCC trial mid-2023.

• Batiraxcept Granted FDA Orphan Drug Designation in Pancreatic Cancer; Phase 1b/2 Trial in PDAC is Advancing
  In February 2023, the Company announced that the U.S. Food and Drug Administration (FDA) granted batiraxcept Orphan Drug Designation (ODD) for the treatment of pancreatic cancer. The Company provided an update on the Phase 1b pancreatic study on September 27, 2022 for 18 patients who had been treated with 15 mg/kg batiraxcept (Days 1 & 15) plus nab-paclitaxel (125 mg/m2 on Days 1, 8, & 15) and gemcitabine (1000 mg/m2 on Days 1, 8, & 15) and have pharmacokinetic data. Consistent with other Phase 1b cancer studies with batiraxcept, there is a relationship between batiraxcept exposures and clinical activity such that 5 of 9 patients in the PDAC study whose batiraxcept levels exceeded the minimum efficacious concentration (MEC) of batiraxcept had a response versus 1 of 9 patients in the low MEC group. Similarly, the mPFS in the high MEC group was 5.6 months (95% CI 2.1, not evaluable) versus 2.7 months (95% CI 1.1, 5.4) in the low MEC group. In May 2022, the Company had reported that batiraxcept was generally well-tolerated in combination with gemcitabine and nab-paclitaxel with no unexpected safety signals. Based on these data, the Company intends to dose an additional 6-18 patients at higher doses (20 mg/kg and potentially 25 mg/kg) to assess whether a higher dose will increase the proportion of patients who will achieve high MEC and increase the clinical activity of batiraxcept in combination with gemcitabine plus nab-paclitaxel. Preliminary data from the 20 mg/kg cohort is expected in the second half of 2023.

• Strengthened Balance Sheet, Adding Funding to Support Operations Beyond PROC Readout
  In January 2022, Aravive raised approximately $9.9 million in net proceeds 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, the date of execution of the stock purchase agreement. 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 $9.3 million in net proceeds 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. In October 2022, the Company raised approximately $40 million in net proceeds from a private placement offering from new biotechnology investors, existing investors and certain of the Company’s management and directors. Combined, the additional capital infusions strengthen the Company’s financial position and fund operations as currently planned into the fourth quarter of 2023, beyond the readout on our Phase 3 PROC trial.

• Strengthened Leadership Team with Experienced Industry Experts
  Throughout 2022, the Company built upon its strong leadership with the appointments of Scott Dove, Ph.D. as Chief Operating Officer, Rudy Howard as Chief Financial Officer and Robert B. Geller, M.D. as Chief Medical Officer.

Fourth Quarter and Full Year 2022 Financial Results
Revenues for the three and twelve months ended December 31, 2022 were approximately $1.5 million and $9.1 million, respectively, compared with approximately $1.0 million and $7.4 million, respectively, for the three and twelve months ended December 31, 2021. Revenues for 2022 and 2021 were derived solely from the Company’s collaboration and license agreement with 3D Medicines, executed in November 2020, to develop and commercialize batiraxcept in oncology indications in China. Revenues represent 1) a portion of initial signing and milestone recorded from 3D Medicines that is recognized at the time it is probable the milestone will be met and 2) a portion of the milestone that is deferred and recognized over the PROC trial period. The increase in revenue for fiscal year 2022 compared to 2021 was driven primarily by increased expenditures related to the PROC trial, which drives the recognition of deferred revenue over the PROC trial period.

Total operating expenses for the three and twelve months ended December 31, 2022 were approximately $21.3 million and $80.0 million, respectively, compared with approximately $14.6 million and $48.1 million, respectively, for the three and twelve months ended December 31, 2021. Research and development expenses for the three and twelve months ended December 31, 2022 were approximately $18.0 million and $66.9 million, respectively, compared with approximately $12.2 million and $37.5 million, respectively, for the three and twelve months ended December 31, 2021. The increase in research and development expense in 2022 compared to the same periods in 2021 is driven by the continued advancement of our clinical trials and increases in CMC-related costs. General and administrative expenses for the three and twelve months ended December 31, 2022 were approximately $3.4 million and $13.0 million, respectively, compared with approximately $2.4 million and $10.6 million, respectively, for the three and twelve months ended December 31, 2021. The increase in general and administrative expense was primarily driven by higher salary expense, higher stock-based compensation expense, higher severance expense, and increased consulting fees.

For the three and twelve months ended December 31, 2022, Aravive reported a net loss of approximately $29.1 million and $76.3 million, or $0.46 per share and $2.10 per share, respectively compared to a net loss of approximately $13.0 million and $39.2 million, or $0.62 per share and $1.95 per share, respectively, for the three and twelve months ended December 31, 2021.

Cash Position
As of December 31, 2022, cash and cash equivalents were approximately $53.7 million, compared to approximately $27.9 million as of September 30, 2022. During October 2022, the Company received a $6 million milestone payment from the Company’s licensee, 3D Medicines, Inc. and raised approximately $40 million in net proceeds from a private placement offering. The Company believes that its existing cash and cash equivalents will be sufficient to sustain operations into the fourth quarter of 2023.
