WILMINGTON, Del., Aug. 11, 2026 (GLOBE NEWSWIRE) -- Inhibikase Therapeutics, Inc. (Nasdaq: IKT) (“Inhibikase” or “Company”), a clinical-stage pharmaceutical company developing IKT-001, a novel once-daily oral anti-proliferative for Pulmonary Arterial Hypertension (“PAH”), today reported financial results for the quarter ended June 30, 2026, and highlighted recent developments.
“During our second quarter and in recent weeks we continued to advance our Phase 3 IMPROVE-PAH study with 26 country regulatory approvals together with the recent initiation of 43 clinical sites across a range of countries,” said Mark Iwicki, Chief Executive Officer of Inhibikase. “Also, during the quarter, favorable results of pre-clinical and Phase 1 studies of IKT-001 were presented at the American Thoracic Society International Conference , with data demonstrating improvements in pulmonary vascular and hemodynamic markers of PAH and lower potential for GI toxicity compared to imatinib mesylate. Together with the recent grant of Orphan Drug Designation from the U.S. FDA and the $50 million proceeds from the sale of shares to RA Capital, Inhibikase is well-positioned to advance IKT-001 toward its potential as the first once-daily oral anti-proliferative offering significant potential benefits to the PAH patient population.”
Recent Developments
• In April 2026, Inhibikase received confirmation from the European Medicines Agency that the Company is permitted to initiate its Phase 3 study in PAH, named IMPROVE-PAH ( I KT-001 for M easuring P ulmonary Vascular R esistance and O utcome V ariables in a Phase 3 E valuation of PAH; NCT07365332). Globally, regulatory approvals for the Phase 3 study have been obtained in 26 countries with 3 additional country approvals pending and 4 additional country regulatory submissions planned. The global IMPROVE-PAH trial is a two-part adaptive Phase 3 study. Part A of IMPROVE-PAH is a double blind, placebo-controlled study in approximately 140 patients with a primary endpoint of change in Pulmonary Vascular Resistance (“PVR”) at Week 24. Part B of IMPROVE-PAH seamlessly begins following the enrollment of the last patient in Part A and adopts an identical format to Part A except the primary endpoint of Part B is change in 6-minute walk distance (“6MWD”) at Week 24 in approximately 346 patients.

• In July 2026, the Company sold 25,000,000 shares of the Company’s common stock to RA Capital Management through its at-the-market (“ATM”) facility for gross proceeds of $50 million. Subsequently, in July 2026, 18,030,000 of these shares of common stock were exchanged for pre-funded warrants to purchase shares of common stock.
• In July 2026, the FDA’s Office of Orphan Products Development granted Orphan Drug Designation (“ODD”) for IKT-001. ODD provides potential development incentives, including eligibility for tax credits on qualified clinical trial costs, exemption from certain FDA user fees, and the potential for seven years of market exclusivity upon regulatory approval.
Presentations
• In May 2026, pre-clinical and Phase 1 data for IKT-001 were presented at the American Thoracic Society (“ATS”) International Conference in Orlando, Florida. These presentations included data demonstrating the following: The potential for IKT-001 to have an improved gastro-intestinal (“GI”) side-effect profile, including gastric emptying benefits and reduced impairment of intestinal motility compared to imatinib mesylate. IKT-001 remains intact in the stomach and the intestine and is not converted to imatinib until it reaches the blood, with in vitro pharmacology studies demonstrating an 18-fold decrease in c-Kit inhibition which has been implicated in the GI side-effects of imatinib. Single doses of IKT-001 resulted in rapid and dose proportional exposure of circulating imatinib, which were well tolerated over a 300-800 mg range with no indication of dose-dependent GI toxicities.

About Inhibikase (www.inhibikase.com)
Inhibikase Therapeutics, Inc. (Nasdaq: IKT) is a clinical-stage pharmaceutical company developing therapeutics to modify the course of cardiopulmonary diseases, namely, Pulmonary Arterial Hypertension (“PAH”), in which aberrant signaling through type III receptor tyrosine kinases, including platelet derived growth factor receptors and a stem cell factor receptor, known as “c-Kit,” has been implicated. Our lead product candidate is IKT-001, a prodrug of imatinib mesylate (“imatinib”), for PAH which is an orphan indication. Imatinib was first approved in the United States in 2001 for various cancers and blood disorders and, following more than 20 years of clinical use, has a well-characterized safety profile with the first reported use of imatinib in PAH occurring in 2005. PAH is a progressive, life-threatening disease characterized by pulmonary vascular remodeling and elevated pulmonary vascular resistance that affects approximately 50,000 Americans. Our single pivotal Phase 3 clinical study in PAH in approximately 180 sites around the world, named IMPROVE-PAH ( I KT-001 for M easuring P ulmonary Vascular R esistance and O utcome V ariables in a Phase 3 E valuation of PAH ), is actively enrolling patients.
