Insights
Inhibikase boosted its cash to fund a pivotal PAH Phase 3 while losses widened on higher R&D and deal-related costs.
Inhibikase ended 2025 with $178.8 million in cash, cash equivalents and marketable securities, up from $97.5 million, mainly after raising $107.6 million through equity and warrant issuance. This gives meaningful financial resources to support the global IMPROVE-PAH pivotal trial.
The annual net loss increased to $48.3 million as research and development reached $29.8 million and selling, general and administrative expenses climbed to $23.6 million. R&D was driven partly by a non-cash $7.4 million write-off and stock-based costs tied to the CorHepta acquisition, while SG&A reflected $1.0 million of severance.
The company reports it has filed regulatory submissions in more than 20 countries and started sites for the IMPROVE-PAH Phase 3 study using IKT-001 for Pulmonary Arterial Hypertension. Subsequent company filings may provide more detail on enrollment progress and any updates to development spending as the trial advances.

Exhibit 99.1
Inhibikase Therapeutics Announces Full Year 2025
Financial Results and Highlights Recent Activity
WILMINGTON, Del., March 26, 2026 — Inhibikase Therapeutics, Inc. (Nasdaq: IKT) (“Inhibikase” or “Company”), a clinical-stage pharmaceutical company developing therapeutics to modify the course of cardiopulmonary diseases namely, Pulmonary Arterial Hypertension (“PAH”), today reported financial results for the year ended December 31, 2025 and highlighted recent developments.
“The fourth quarter of 2025 was a transformational quarter for the Company as we transitioned to a global pivotal Phase 3 clinical study in Pulmonary Arterial Hypertension following receipt of a Written Response from a Type C interaction from the United States Food and Drug Administration,” said Mark Iwicki, Chief Executive Officer of Inhibikase. “With regulatory submissions in over 20 countries already filed and our first sites initiated, we are well-placed to advance enrollment in our global pivotal study, called IMPROVE-PAH, in PAH.”
Recent Developments:
| • | The Company is advancing IKT-001 into a global pivotal Phase 3 study in PAH: |
| • | The Phase 3 study, named IMPROVE-PAH (IKT-001 for Measuring Pulmonary Vascular Resistance and Outcome Variables in a Phase 3 Evaluation of PAH; NCT07365332), has been initiated with regulatory approval and the recent activation of our first clinical sites in the United States. |
| • | Following receipt from the United States Food and Drug Administration (the “FDA”) of the Written Response from the Company’s Type C meeting interaction with the agency, the Company is initiating 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 Pulmonary Vascular Resistance (“PVR”) at Week 24. |
| • | Part B of IMPROVE-PAH, which shall immediately commence enrollment following enrollment of the last patient in Part A, adopts an identical format to Part A, except the primary endpoint will be 6-minute walk distance (“6MWD”) at Week 24 in approximately 346 patients. |
| • | The Company believes this adaptive Phase 3 study design has important advantages including: (1) permitting a 12-week dose-titration phase designed to get patients to the highest tolerable dose of IKT-001; (2) uninterrupted enrollment between Part A and Part B; and (3) the ability to, if necessary, undertake a sample size re-estimation for Part B based on Part A findings. |
| • | IMPROVE-PAH is expected to be conducted in up to approximately 180 sites around the world. |
| • | The Company is progressing regulatory approvals with submissions in over 20 countries together with receiving confirmation of acceptance under “Facilitating and Accelerating Strategic Trials in the European Union”, called FAST-EU, which is a pilot initiative that commenced on January 30, 2026 to accelerate the approval of multinational clinical trials. FAST-EU offers a potential maximum 10-week (70-day) timeline for authorization, integrating Ethics Committee opinions and improving efficiency within the European Union Clinical Trials Information System. |
| • | Inhibikase successfully completed various required pre-clinical studies that are necessary to support an application to the FDA for Orphan Drug Designation for delivery of IKT-001 for PAH. Various information from these studies is expected to be presented at the American Thoracic Society International Conference to be held in Orlando, Florida on May 17th and 20th, 2026. |
| • | In November 2025, the Company completed a $115 million underwritten public offering of its common stock and pre-funded warrants. |
| • | Aggregate gross proceeds from this offering were approximately $115 million, before deducting underwriting discounts and commissions and other offering expenses, excluding the exercise of any pre-funded warrants. |

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.
