Company to host conference call and webcast on November 15, 2022 at 8:00am ET

BOSTON and ATLANTA, Nov. 14, 2022 /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 third quarter ended September 30, 2022 and highlighted recent developments.

"While the FDA clinical hold on our IkT-148009 programs for Parkinson's disease and Multiple System Atrophy was unexpected, we are actively working with the agency to understand their concerns and resolve them as soon as possible. To date we have not seen any serious adverse events in our Phase 2a '201' trial and believe the recently presented results from our Phase 1/1b '101' trial continues to support the safety, tolerability and pharmacokinetics of IkT-148009," commented Milton Werner, Ph.D., President and Chief Executive Officer of Inhibikase. "As we work to resolve the clinical hold, we remain on track to initiate the '501' bioequivalence study to evaluate IkT-001Pro for the treatment of stable phase Chronic Myelogenous Leukemia in the fourth quarter. In addition, we will continue to gather preclinical data for IkT-148009 in MSA and expect to advance a second animal model study in the fourth quarter. We remain committed to our mission to improve the lives of patients suffering from devastating neurodegenerative diseases and look forward to providing updates as appropriate."

Recent Developments and Upcoming Milestones:

• Phase 2a '201' Clinical Trial of IkT-148009 for the Treatment of Parkinson's Disease: In August 2022, Inhibikase announced dosing of the first patient in its '201 trial' evaluating IkT-148009 for the treatment of Parkinson's disease. The 201 trial is a 1:1:1:1 randomized, double-blind, twelve-week dosing trial evaluating three-dose levels of IkT-148009. The primary endpoints will assess the safety, tolerability and steady-state pharmacokinetics of IkT-148009. The trial will also measure a hierarchy of fifteen Parkinson's-related disease assessments in the brain and gut as secondary or exploratory endpoints. On November 7, 2022, Inhibikase announced that the U.S. Food and Drug Administration ("FDA") had issued a clinical hold on the IkT-148009 development programs. The FDA indicated it will provide an official clinical hold letter to Inhibikase within 30 days to explain the reason for this action. To date, the Company has dosed eleven patients in the trial and will conduct a blinded safety assessment, but there have been no serious adverse events seen in the trial to date and only two mild adverse events have been recorded. Since none of the initial eleven patients completed the study, once the clinical hold is lifted, the study will need to be restarted.
• Presented data supporting c-Abl inhibitor therapy and the patient experience with IKT-148009 at two expert industry and academic conferences. In September 2022, Inhibikase presented data at two scientific conferences highlighting five animal model studies of acute, inherited and sporadic disease demonstrating the functional benefit of IkT-148009 in Parkinson's disease. At the annual Movement Disorder Society Congress in Madrid Spain, Inhibikase presented data detailing the dosing experience of healthy subjects and Parkinson's patients from multiple doses of IkT-148009 therapy between 12.5 mg and 325 mg for up to 7 days. In addition, an assessment of Parkinson's-related disease measures demonstrated that IkT-148009 did not worsen disease.
  
  At the Van Andel Institute's Grand Challenges in Parkinson's Disease conference, the Company elaborated on the fundamental studies of five distinct animal models of either acute, inherited or idiopathic disease that forms the basis of the Company's understanding of Parkinson's disease initiation and the critical role of c-Abl in the disease process. Data presented also demonstrated that treatment with IkT-148009 in animals led to functional recovery correlating with clearance of pathological alpha-synuclein protein. Clinical data presented at both conferences from the Phase 1/1b '101' trial demonstrated a favorable safety and tolerability profile up to a dose of 325 mg with no clinically significant adverse events observed.

• Received FDA Clearance for Investigational New Drug (IND) Application for IkT-001Pro for Chronic Myelogenous Leukemia (CML): In August 2022, Inhibikase received clearance by the FDA for its IND application for IkT-001Pro, the Company's prodrug formulation of imatinib mesylate designed to enhance the safety and efficacy of imatinib (marketed as Gleevac^®). The Company is advancing IkT-001Pro into a single, ascending dose bioequivalence study for safety and efficacy evaluation of IkT-001Pro. The study will enroll approximately 56 male and female healthy volunteers between the ages of 25 and 55 who will be administered IkT-001Pro at one of three doses. In addition to safety and efficacy evaluations, the study will be designed to identify a dose that mimics the systemic exposure and pharmacokinetics of 400 mg imatinib mesylate, the standard-of-care dose for Stable-Phase CML. The Company expects to dose the first patient in its '501' bioequivalence study in the fourth quarter of 2022.
• Appointed Gisele Dion to Board of Directors: In September 2022, Inhibikase appointed Gisele Dion to the Board of Directors. Ms. Dion serves as chair of the Audit Committee, as well as a member of the Compensation Committee. Ms. Dion brings extensive experience in the public company space and has previously spearheaded financial, accounting and M&A strategies across large pharma.

Net loss for the nine months ended September 30, 2022, was $13.78 million or $0.55 per share, compared to a net loss of $9.74 million, or $0.61 per share in the comparable period in 2021.

R&D Expenses: Research and development expenses were $2.98 million for the three months ended September 30, 2022, compared to $3.15 million in the comparable quarter in 2021. The $0.17 million decrease in research and development expenses for the third quarter 2022 was due to a $0.77 million decrease in stock compensation partially offset by a net increase of $0.60 million of all other normal R&D expenses expenditures as the Company continued to focus on and progress its PD clinical trial activities.

Research and development expenses were $8.98 million for the nine months ended September 30, 2022 compared to $7.97 million in comparable period in 2021. The $1.01 million increase was driven by a $0.49 million decrease in non-cash stock compensation expenses offset by a $0.48 million increase in compensation and related costs, a $0.90 million increase in external R&D services and consultants, a $0.08 million increase in legal and a net increase of $0.04 million in all other normal R&D expensed.

SG&A Expenses: Selling, general and administrative expenses for the three months ended September 30, 2022 were $1.54 million compared to $1.64 million for the comparable quarter in 2021. The decrease was primarily driven by a $0.36 million decrease in stock compensation expense partially offset by increases of $0.13 million and $0.08 million of legal fees and compensation and related costs, respectively, and a $0.04 million net increase in all other normal selling, general and administrative expenses.

Selling, general and administrative expenses for the nine months ended September 30, 2022 were $4.87 million compared to $4.85 million for comparable period in 2021. The major drivers were a $1.07 million decrease in non-cash stock compensation expense for the nine months ended September 30, 2022 compared to the nine months ended September 30, 2021. The stock compensation decrease was offset by increased compensation and related costs of $0.38 million, increased legal fees of $0.35 million, increased compliance, regulatory and consultants of $0.30 million and a net increase all other normal selling, general and administrative expenses of $0.02 million.

Cash Position: Cash, cash equivalents and marketable securities were $26.5 million as of September 30, 2022.
