Exhibit 99.1
Inhibikase Therapeutics Announces Second Quarter
2025 Financial Results and Highlights Recent Activity
August 14, 2025 — 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 quarter ended June 30, 2025 and highlighted recent developments.
“During our second quarter of 2025, we continued to position the Company to advance IKT-001 toward a late-stage clinical trial in PAH,” said Mark Iwicki, Chief Executive Officer of Inhibikase. “We have now finalized our study protocol, and we expect to initiate our Phase 2b clinical study of IKT-001, our re-engineered prodrug of imatinib mesylate, in PAH in the second half of 2025.”
Multiple studies including both Phase 2 and the Phase 3 IMPRES study previously demonstrated that imatinib mesylate (“imatinib”), an anti-proliferative tyrosine kinase inhibitor, was highly efficacious in PAH. Notably in the IMPRES study, patients that maintained 400 mg of imatinib for greater than 50% of the treatment period showed a placebo adjusted 45-meter improvement in 6-minute walk distance (“6MWD”) which represents best-in-class improvements for patients afflicted by PAH. More recently, a contemporary study in the American Journal of Respiratory and Critical Care Medicine demonstrated that higher exposures of imatinib were associated with a larger improvement in total pulmonary resistance (“TPR”). The 400 mg dose of imatinib exhibited the greatest impact on TPR and, even though the majority of patients completed the study at 200 mg or less, the magnitude of the hemodynamic change for the study was noted to compare favorably with recent studies of novel therapies added to background treatment. The Company believes this supports its thesis that IKT-001 has the potential to minimize GI side effects while maximizing the highly efficacious outcomes observed at 400 mg across multiple studies.
Recent Developments:
| • | Advancement of IKT-001 as a therapy in PAH: |
| • | During the first half of 2025, the Company evaluated potential study designs and obtained feedback from various key opinion leaders before finalizing a clinical study protocol for its forthcoming Phase 2b study, known as IMPROVE-PAH. |
| • | IMPROVE-PAH is a multi-center, randomized, double-blind, placebo-controlled study of approximately 150 PAH participants. Participants under IMPROVE-PAH will be randomized 1:1:1 to receive 300 mg IKT-001, 500 mg IKT-001, or placebo once daily for 26 weeks, in addition to stable background PAH therapy. The Company’s bioequivalence studies previously confirmed that 500 mg of IKT-001 has comparable exposure in humans to 380 mg of imatinib. The primary efficacy endpoint is change in pulmonary vascular resistance at Week 26. Secondary endpoints include 6MWD, World Health Organization functional class, and pharmacokinetics. The study protocol also includes an interim safety review for study continuance by the Data Safety Monitoring Board with at least 50 patients at 12-weeks of follow-up. |
| • | The Company expects to initiate IMPROVE-PAH in the second half of 2025. |

Scientific and Clinical Rationale

Imatinib Mechanism of Action in PAH Targets the Underlying Cause of PAH CONFIDENTIAL Modified from Savage and Antman, 2005 and Barst, R J Clin Invest 2005 Overactive kinases implicated in aberrant cell proliferation and migration in the pulmonary vasculature Imatinib inhibits the tyrosine kinase activity of PDGFR and c-kit , blocking cell signaling that drives vascular remodeling Pulmonary vasculature with aberrant cell proliferation Normal pulmonary vasculature Adventitia VSMCs Internal elastic lamina Microfibroblasts and extracellular matrix (neointima) Endothelium Adventitia VSMCs Internal elastic lamina Endothelium Imatinib inhibits the tyrosine kinase activity of PDGFR and c-kit , blocking cell signaling that drives vascular remodeling Proliferation

Imatinib Demonstrated Reversal of PAH in Standard Animal Model Day 0 MCT d42 MCT d42/+imatinib Schermuly et al., JCI 2005 Reversal of right ventricular pressure Improved survival Reversal of vascular remodeling STI571 = imatinib; MCT = monocrotaline *P < 0.05 versus control; †P < 0.05 versus MCT at day 28 or hypoxia at day 21; ‡P < 0.05 versus MCT at day 42 or hypoxia at day 35. Imatinib reverses pulmonary vascular remodeling, right ventricular pressure / remodeling and improves survival

IMPRES – Imatinib Phase 3 Study Randomized, double blind, placebo controlled study to assess the efficacy, safety and tolerability of 400mg imatinib once daily (n=202) Primary Endpoint Change in 6MWD at 24 weeks Secondary Endpoints Changes in hemodynamics (PVR, CO, mPAP, RAP) at 24 weeks Time to clinical worsening Weeks 0 4 8 12 16 20 24 Imatinib (n=103) Placebo (n=99) Titration 200mg 400mg with ability to down titrate to 200mg if unable to tolerate 400mg Key Inclusion Criteria Functional Class II-IV 2 or more background PAH therapies PVR ≧ 800 dynes.s.cm-5 6MWD ≥150 meters and ≤ 450meters PVR = pulmonary vascular resistance; CO = cardiac output; mPAP = mean pulmonary arterial pressure; RAP = right arterial pressure; 6MWD = 6-minute walk distance

Phase 3 IMPRES: Statistically Significant Improvement in Function & Hemodynamics 32-meter improvement in 6WMD and 32% reduction in PVR at week 24 Hoeper et al; Circulation 2013 Phase 3 IMPRES study hit its primary endpoint along with key clinically relevant secondary endpoints Change in 6MWD Change in Pulmonary Vascular Resistance Change in Cardiac Output PVR = Pulmonary Vascular Resistance; 6MWD= 6 Minute Walk Distance test

Phase 3 IMPRES: 3 of the Top 5 AEs were GI Related Majority of patients were unable to maintain 400 mg target dose of imatinib Hoeper et al; Circulation 2013 AE = Adverse event; GI = Gastrointestinal Phase 3 IMPRES hit its primary endpoint DESPITE only 48/103 participants maintaining 400mg dose for at least half of the treatment period Imatinib n=103 (%) Placebo n=98 (%) Adverse Events 100 (97) 94 (96) Nausea 57 (55) 23 (24) Peripheral edema 45 (44) 20 (20) Diarrhea 36 (35) 19 (19) Vomiting 31 (30) 10 (10) Periorbital edema 30 (29) 7 (7) The AE profile in IMPRES was similar to the established AE profile of imatinib in other indications Poor tolerance prevented most patients from maintaining the target dose of 400 mg of imatinib IKT-001 is a novel pro-drug of imatinib designed for better GI tolerability allowing optimal efficacy

IMPRES: Efficacy Impacted by Tolerability of 400mg Per Day Patients able to sustain 400mg dose showed greater improvements in 6MWD and PVR Changes in PVR at Week 24 Changes in 6MWD at Week 24 N=40 N=24 N=79 N=44 N=23 N=78 Hoeper et al; Circulation 2013 Suppl. Appendix Meters Dynes/sec/cm-5 (Baseline*: 355 meters imatinib; 366 meters placebo) (Baseline*: 1202 dynes/sec/cm-5 imatininb; 1181 dynes/sec/cm-5 placebo) * Baseline data is not available for the sub-population of patients on 400mg of imatinib for > 50% of treatment so baseline data above reflects entire study population. PVR= Pulmonary vascular resistance; 6MWD = 6-minute walk distance 45 meter placebo adjusted improvement in 6MWD

Contemporary Study of Imatinib Supports 400mg Dose for Best Efficacy Higher Exposure associated with larger treatment effect Higher Exposure = Larger Improvement More than 50% of subjects who completed the study were on 200mg per day or less One-third of patients who started the study at either 300mg or 400mg had dose-limiting toxicity at Week 4 and subsequent dose reduction Only 5 patients completed the study at 300mg or 400mg per day Percentage change in total pulmonary resistance from baseline at 60 days in relation to plasma level (area under curve in μg*h/L) of imatinib at steady state (red-100md QD, orange-200mgQD, cyan-300mg QD, blue-400mg QD) Doses over 200mg per day were poorly tolerated * Rothman et al., AJRCCM 2025. 17 patient open-label study. Patients were implanted with the CardioMEMS HF System which is a small, wireless sensor implanted in the pulmonary artery to monitor pulmonary artery pressure. Patients remained in the study for up to 24 weeks.

Rapid and Sustained Hemodynamic Effect & Disease Modification of Imatinib in PAH Early & Continued Improvement 24% reduction in Total Pulmonary Resistance (TPR); Patients at 200mg or less leaves “efficacy on the table” 24% Reduction in TPR Early Improvement in TPR Slow return to BL * Rothman et al., AJRCCM 2025. 17 patient open-label study.
