• Company to host conference call on Tuesday, August 15, 2023 at 8:00 a.m. ET

BOSTON and ATLANTA, Aug. 14, 2023 /PRNewswire/ -- Inhibikase Therapeutics, Inc. (Nasdaq: IKT) (Inhibikase or Company), a clinical-stage pharmaceutical company developing protein kinase inhibitor therapeutics to modify the course of Parkinson's disease ("PD"), Parkinson's-related disorders and other diseases of the Abelson Tyrosine Kinases, today reported financial results for the second quarter ended June 30, 2023 and highlighted recent developments.

"We have made significant clinical progress in the first half of 2023," said Dr. Milton H. Werner, President and Chief Executive Officer of Inhibikase. "Our Phase 2 '201' trial of IkT-148009 for the treatment for Parkinson's disease is progressing, with screening ongoing at 22 sites and up to 32 sites expected to be open and screening by close of the third quarter.  Patients are enrolling and the first patient has completed 12 weeks dosing as of the date of this release.  Our newly launched patient portal provides a central hub for patient engagement with our clinical sites, allows patients to test their suitability for participation in the study and acts as a launching point for engagement with community neurologists, caregivers and support groups.  The '501' trial evaluating IkT-001Pro, our imatinib prodrug, has also reached important milestones, including the completion of the pivotal trial phase to confirm the bioequivalent dose.  Following discussions with the FDA, we are considering the addition of a high dose bioequivalence cohort between IkT-001Pro and 600 mg imatinib to further substantiate the safety benefit of imatinib delivered as prodrug. As we look ahead, our focus remains on execution in our clinical programs, and we expect to provide additional updates as enrollment progresses in our '201' trial later this year and a full data description from the '501' trial."

Recent Developments and Upcoming Milestones:

• The Phase 2 '201' clinical trial of IkT-148009 is screening and enrolling patients: 22 of 35 planned clinical sites are screening and enrolling patients, with the first patient having completed the 12 week dosing regimen. Up to 32 clinical sites are anticipated to be open for enrollment and screening patients by close of the third quarter. Additionally, the Company has launched a medical and patient awareness campaign to advance the pace of enrollment in the trial as well as provide patients with a central hub to learn about the trial through www.the201trial.com.
• Completed bioequivalence phase of the '501' trial of IkT-001Pro: In June 2023, Inhibikase completed the pivotal phase of the '501' trial and selected a bioequivalent dose of IkT-001Pro. The Company expects to report data in the near term. With agreement on trial design finalized with the FDA, Inhibikase is considering to expand the 501 trial to evaluate the potential safety benefit of high dose imatinib delivered by IkT-001Pro in the third quarter.
• Advancing preclinical development of IkT-148009 in MSA: Two models have been evaluated, one that measures the ability of IkT-148009 to block progression early in the course of disease, and a second that evaluates the ability to correct functional loss and neurodegeneration late in the course of disease. The Company has nearly completed the evaluation of the first model, which showed that IkT-148009 dosed once daily for 20 weeks blocked functional loss and preserved neural anatomy when IkT-148009 administration occurred early in the course of disease. Prevention of functional loss in this model was accompanied by significant reduction of the underlying alpha-synuclein pathology. Outcomes from the study of IkT-148009 when treatment begins late in the course of disease is expected to be completed by the end of 2023.
• Regained Compliance with Nasdaq Listing Requirements: In June 2023, the Company effected a 1-for-6 reverse stock split of its common stock. The reverse split was approved by Inhibikase shareholders and came into effect on June 30, 2023. The reverse stock split and subsequent trading performance resulted in restoration of full compliance with the minimum bid price requirement of $1.00 per share under Nasdaq Listing Rule 5550(a)(2); the Company is in compliance with all other applicable listing standards.

Second Quarter Financial Results

Net Loss: Net loss for the quarter ended June 30, 2023 was $5.8 million, or $1.11 per share, compared to a net loss of $4.6 million, or $1.10 per share in the quarter ended June 30, 2022.

R&D Expenses: Research and development expenses were $4.5 million for the quarter ended June 30, 2023 compared to $3.0 million in the quarter ended June 30 2022. The increase was primarily due to the Company's ongoing Phase 2 '201' PD clinical trial costs.

SG&A Expenses: Selling, general and administrative expenses for the quarter ended June 30, 2023 were $1.8 million compared to $1.7 million for the quarter ended June 30, 2022. The increase was driven by a net increase in normal selling, general and administrative expenses.

Cash Position: Cash and cash equivalents and marketable securities were $20.9 million as of June 30, 2023. The Company expects that existing cash and cash equivalents will be sufficient to fund operations into the fourth quarter of 2024.
