Inhibikase Therapeutics Reports Third Quarter Financial Results and Highlights Recent Period Activity

Company to host conference call on Wednesday, November 15, 2023 at 8:00 a.m. ET

BOSTON and ATLANTA, Nov. 14, 2023 (GLOBE NEWSWIRE) -- 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 third quarter ended September 30, 2023 and highlighted recent developments.

“We are very pleased with the progress of the last quarter,” noted Dr. Milton H. Werner, President and Chief Executive Officer of Inhibikase. “Our efforts to improve drug delivery for protein kinase inhibitors brought IkT-001Pro to pre-NDA stage just 15 months after opening of the IND. Our neurodegenerative disease programs with risvodetinib are expanding, with 20% of the Phase 2 201 Trial in untreated Parkinson’s disease enrolled coupled with our efforts to initiate a Phase 2 program in Multiple System Atrophy. Finally, our internal and external medicinal chemistry programs are yielding important insights into the design of next generation Abl kinase inhibitors that could lead to a pipeline of beneficial products for Abl kinase-related diseases. Collectively, this has been a very productive period for the Company.”

Recent Developments and Upcoming Milestones:

• Advancing Phase 2 '201' Trial of Risvodetinib (IkT-148009) in untreated Parkinson’s disease: As of November 10, 2023, 28 sites are open and actively evaluating prospective trial participants. Twenty-four participants have been enrolled, 7 prospective participants are in screening and 15 potential participants are going through informed consents.
  
  The 201 Trial patient portal (www.the201trial.com) has been visited by more than 20,000 unique people since launch in September, 2023. The pre-qualification process has led to 201 unique individuals to contact open clinical sites, the first step in the evaluation process that could lead to enrollment. Monthly site enrollments have increased month-over-month since this patient outreach program was initiated.

• Unblinded functional analysis from the 201 Trial are encouraging: In August 2023, unblinded functional assessments of 11 patients with untreated Parkinson’s disease were presented at the Movement Disorder Congress in Copenhagen, Denmark. These participants were withdrawn from the trial following the FDA’s temporary clinical hold in November, 2022, which was lifted January, 2023. These assessments showed that patients receiving the 200 mg dose of risvodetinib (N=3) saw a greater than 10 point improvement over placebo in the sum of motor and non-motor scores after once daily treatment for up to 11 weeks; by contrast, a typical patient with Parkinson’s disease would worsen by 3 to 6 points in the sum of motor and non-motor score assessments over a 12 month period. While the number of treated participants is too small for the Company to conclude a clinical benefit, these early data are cautiously encouraging.
• Received Orphan Drug Designation in Multiple System Atrophy (MSA): In October 2023, risvodetinib was granted Orphan Drug Designation by the FDA for the treatment of MSA. In animal model studies of MSA, risvodetinib was shown to be therapeutically active. The designation by the FDA underscores the need for innovative treatment options for patients afflicted with this rare and rapidly progressing Parkinson’s-related disorder. The Company is pursuing a comparable designation in the European Union, or E.U., as part of its efforts to initiate a Phase 2 clinical trial to evaluate risvodetinib in MSA. The Company is discussing conduct of the trial with private foundations, Federal and industry stakeholders in an effort to initiate this trial in the future.
• Completed the ‘501’ bioequivalence studies with IkT-001Pro: In October 2023, Inhibikase completed its bioequivalence studies of IkT-001Pro, measuring the bioequivalent dose to both 400 mg and 600 mg imatinib mesylate. The study enrolled a total of 66 healthy volunteers in three parts. In single dose studies, bioequivalent IkT-001Pro induced fewer neurological, musculoskeletal and gastrointestinal adverse events relative to 400 mg imatinib mesylate. Gastrointestinal adverse events were more persistent for imatinib mesylate in the study evaluating bioequivalence to 600 mg imatinib mesylate. Measures of bioequivalence along with safety and tolerability data are being submitted as briefing materials for a pre-NDA meeting with the FDA to reach agreement on the requirements for approval of IkT-001Pro under the 505(b)(2) statute.
• Initiated preclinical development of second-generation c-Abl inhibitors: In August 2023, Inhibikase initiated preclinical development of new molecules arising from internal medicinal chemistry and external collaborations identifying second generation molecules that could enhance suppression of neurodegeneration or address other diseases that could benefit from Abl kinase inhibition.

Third Quarter Financial Results

Net Loss: Net loss for the three months ended September 30, 2023 was $4.60 million, or $0.86 per share, compared to a net loss of $4.49 million, or $1.06 per share in the quarter ended September 30, 2022.

R&D Expenses: Research and development expenses were $3.23 million for the quarter ended September 30, 2023 compared to $2.98 million in the quarter ended September 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 September 30, 2023 were $1.62 million compared to $1.54 million for the quarter ended September 30, 2022. The increase was driven by net increase in normal selling, general and administrative expenses.

Cash Position: Cash, cash equivalents and marketable securities were $16.83 million as of September 30, 2023. The Company expects that existing cash and cash equivalents will be sufficient to fund operations into the fourth quarter of 2024.

Inhibikase Therapeutics, Inc. (Nasdaq: IKT) is a clinical-stage pharmaceutical company developing therapeutics for Parkinson's disease and related disorders. Inhibikase's multi-therapeutic pipeline has a primary focus on neurodegeneration and its lead program risvodetinib, an Abelson Tyrosine Kinase (c-Abl) inhibitor, targets the treatment of Parkinson's disease inside and outside the brain as well as other diseases that arise from Abelson Tyrosine Kinases. Its multi-therapeutic pipeline is pursuing Parkinson's-related disorders of the brain and GI tract, orphan indications related to Parkinson's disease such as Multiple System Atrophy, and drug delivery technologies for kinase inhibitors such as IkT-001Pro, a prodrug of the anticancer agent imatinib mesylate that the Company believes will provide a better patient experience with fewer on-dosing side-effects. The Company's RAMP™ medicinal chemistry program has identified a number of follow-on compounds to risvodetinib to be potentially applied to other cognitive and motor function diseases of the brain. Inhibikase is headquartered in Atlanta, Georgia with an office in Lexington, Massachusetts.
