"During our third 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 expect to initiate our Phase 2b clinical study of IKT-001, our prodrug of imatinib mesylate, in PAH during the fourth quarter of 2025."

Recent Developments:

Advancement of IKT-001 as a therapy in PAH:
The proposed Phase 2b IMPROVE-PAH trial 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 383 mg of imatinib. The primary efficacy endpoint is change in pulmonary vascular resistance at Week 26. Secondary endpoints include 6-minute walk distance, 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 has been actively working with potential sites and presently expects to initiate IMPROVE-PAH in the fourth quarter of 2025.
Appointed veteran biopharma executive Timothy Pigot as the Company’s Chief Commercial and Strategy Officer.
The Company also expects to present at the Jefferies Global Healthcare Conference in London on Monday, November 17th, 2025.
