Inhibikase Therapeutics Announces Third Quarter 2026 Financial Results and Highlights Recent Activity

WILMINGTON, Del., Nov. 10, 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 September 30, 2026, and highlighted recent developments.

“During our third quarter and in recent weeks we continued to advance our Phase 3 IMPROVE-PAH study, for which we have obtained 28 country regulatory approvals in the U.S. and E.U., with 79 clinical sites activated across a range of countries,” said Mark Iwicki, Chief Executive Officer of Inhibikase. “We continue to expand our clinical footprint and look forward to additional country and site activations over the coming months. Supported by the $50 million proceeds from the sale of shares to RA Capital in July, 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

• As of November 2026, regulatory approvals for the IMPROVE-PAH (IKT-001 for Measuring Pulmonary Vascular Resistance and Outcome Variables in a Phase 3 Evaluation of PAH; NCT07365332) have been obtained in 28 countries globally; 79 of a planned 180 clinical sites have been activated.
  
  
  • 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.
    
  • An interim safety readout for Part A of the Phase 3 IMPROVE-PAH study (n=50) is planned for the first half of 2027.
    
• In October 2026, the Company announced the appointment of Scott M. Wasserman, MD, to the Company’s Board of Directors. Dr. Wasserman is currently the Chief Medical Officer of Kailera Therapeutics, a clinical-stage company developing GLP-1-based therapeutics for obesity and related conditions. Dr. Wasserman is a cardiologist with more than two decades of experience in clinical development and company leadership.
  
• In July 2026, the Company sold 25,000,000 shares of the Company’s common stock to new shareholder 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.
  

Nonclinical and Development Update

Over the last few months and extending into 2027, the Company has enhanced its focus on additional nonclinical activities that have the potential to broaden the scientific rationale for IKT-001 across the following themes:

• Sotatercept Combination: Building on previously published nonclinical evidence supporting the potential to provide PAH patients with additive hemodynamic improvements via the complementary combination of IKT-001 and an active signaling inhibitor, Inhibikase’s additional nonclinical studies are focused on deepening the mechanistic and translational rationale for combining IKT-001 with sotatercept with results expected progressively, starting in the first quarter of 2027.   Additionally, the Company has begun regulatory filings to support combination therapy within Part B of the ongoing Phase 3 program.
  
• Group 2 Potential: Beyond the Company’s current single pivotal Phase 3 in Group 1 PAH patients, Inhibikase is undertaking various nonclinical activities to explore the potential of IKT-001 to improve myocardial fibrosis and diastolic function. These efforts will evaluate the potential of IKT-001 to address both pulmonary vascular remodeling and underlying cardiac dysfunction in HFpEF-associated pulmonary hypertension with results expected during 2027.
  
• Group 3 Potential: The Company is also evaluating whether IKT-001 has the potential to reduce pulmonary vascular resistance and vascular remodeling, improve right-heart function, and provide therapeutic benefit in PH-ILD (Group 3) nonclinical models. These studies will explore the potential of IKT-001 to reduce the abnormal remodeling of pulmonary arteries, as well as a possible direct antifibrotic effect, with results expected during late 2027 or early 2028.

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 (IKT-001 for Measuring Pulmonary Vascular Resistance and Outcome Variables in a Phase 3 Evaluation of PAH), is actively enrolling patients.
