Notes to Financial Statements
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	1. Formation and Business of the Company Aravive, Inc. (“Aravive” or the “Company”) was incorporated on December 10, 2008 in the State of Delaware. Aravive Biologics, Inc. (“Aravive Biologics”), the Company's wholly owned subsidiary, was incorporated in 2007. Aravive is a clinical-stage oncology company developing transformative treatments designed to halt the progression of life-threatening diseases, including cancer and fibrosis. Batiraxcept (formerly AVB-500), is an ultrahigh-affinity, decoy protein that targets the GAS6-AXL signaling pathway. By capturing serum GAS6, batiraxcept starves the AXL pathway of its signal, potentially halting the biological programming that promotes disease progression. AXL receptor signaling plays an important role in multiple types of malignancies by promoting metastasis, cancer cell survival, resistance to treatments, and immune suppression. In July 2016, Aravive Biologics was approved for a $20.0 million Product Development Award from the Cancer Prevention and Research Institute of Texas (“CPRIT Grant”). The CPRIT Grant was expected to allow Aravive Biologics to develop the product candidate referenced above through clinical trials. The CPRIT Grant was effective as of June 1, 2016 and terminated on November 30, 2019. The Company has received all $20 million of the grant proceeds and has incurred all of the grant award proceeds by the termination date. Aravive Biologics’ royalty and other obligations, including its obligation to repay the disbursed grant proceeds under certain circumstances, survive the termination of the grant contract. The CPRIT Grant was subject to customary CPRIT funding conditions including a matching funds requirement where Aravive Biologics matched 50% of funding from the CPRIT Grant. Consequently, Aravive Biologics was required to raise $10.0 million in matching funds over the three-year project. Aravive Biologics raised all of its required $10.0 million in matching funds. Aravive Biologics’ award from CPRIT requires it to pay CPRIT a portion of its revenues from sales of certain products, or received from its licensees or sublicensees, at tiered percentages of revenue in the low- to mid-single digits until the aggregate amount of such payments equals 400% of the grant award proceeds, and thereafter at a rate of less than one percent for as long as Aravive Biologics maintains government exclusivity. In April 2020, the Company entered into a license and collaboration agreement with WuXi Biologics (Hong Kong) Limited, the objective of which is to identify and develop novel high-affinity bispecific antibodies against CCN2, also known as connective tissue growth factor ("CTGF"), implicated in cancer and fibrosis, and identified from a similar target discovery screen that identified the significance of the AXL/GAS6 pathway in cancer. However, in August 2022, the Company temporarily halted work on the CTGF program with WuXi in an effort to focus all resources on the clinical programs. In November 2020, the Company entered into a collaboration and license agreement with 3D Medicines Inc. ("3D Medicines") (the “Agreement or the 3D Medicine Agreement”), whereby the Company granted 3D Medicines an exclusive license to develop and commercialize products that contain batiraxcept as the sole drug substance for the diagnosis, treatment or prevention of human oncological diseases, in mainland China, Taiwan, Hong Kong and Macau (the "Territory") for an upfront cash payment of $12 million. During the second quarter of 2021, the Company received a $6 million development milestone from 3D Medicines, for completing our first clinical milestone with 3D Medicines, dosing the first patient in its Phase 3 trial of batiraxcept in PROC. In August 2021, the Company received a $3 million development milestone payment from 3D Medicines based on the Center for Drug Evaluation ("CDE") of the China National Medical Products Administration ("NMPA") approval of the Investigational New Drug application ("IND") submitted by 3D Medicines to participate in the Company’s international batiraxcept Phase 3 PROC clinical trial. In October 2022, the Company received a $6 million development milestone payment from 3D Medicines based on the initiation of the global Phase 3 platinum resistant ovarian cancer ("PROC") clinical trial in the Territory for the development of batiraxcept. As consideration for the rights granted as part of a license agreement that Aravive Biologics entered into in 2012 with Leland Stanford Junior University (“Stanford University”) for intellectual and tangible property rights relating to biologic inhibitors for therapeutic targeting the receptor tyrosine kinase AXL, Aravive Biologics is obligated to pay yearly license fees and milestone payments, and a royalty based on net sales of products covered by the patent-related rights. More specifically, Aravive Biologics is obligated to pay Stanford University (i) annual license payments (ii) milestone payments of up to an aggregate of $1,000,000 upon achievement of clinical and regulatory milestones, and (iii) royalties equal to a percentage (in the low single digits) of net sales of licensed products; provided that the annual license payments made will offset (and be credited against) any royalties due in such license year. In the event of a sublicense to a third party of any rights based on the patents that are solely owned by Stanford University, Aravive Biologics is obligated to pay royalties to Stanford University equal to a percentage of what Aravive Biologics would have been required to pay to Stanford University had it sold the products under sublicense itself. In addition, in such event it is required to pay to Stanford University a percent of sublicensing income. In the event of a termination, Aravive Biologics will be obligated to pay all amounts that accrued prior to such termination. *Unaudited Interim Financial Information* In the opinion of the Company’s management, the accompanying unaudited condensed consolidated financial statements contain all adjustments, consisting of only normal recurring adjustments, necessary for a fair statement of its financial position as of March 31, 2023 and, its results of operations for the three months ended March 31, 2023 and 2022, the condensed consolidated statement of stockholders' (deficit) equity for the three months ended March 31, 2023 and 2022, and cash flows for the three months ended March 31, 2023 and 2022.
