Inhibikase Therapeutics Reports Full Year 2022 Financial Results and Highlights Recent Period Activity

BOSTON and ATLANTA, March 31, 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 full year ended December 31, 2022 and highlighted recent developments.

"2022 was an important year for Inhibikase as we continued to advance and validate our lead asset IkT-148009 in the clinic and through data presentations at several notable scientific and industry conferences. While the FDA clinical hold on our IkT-148009 programs was an unexpected challenge, we were pleased to announce that the FDA lifted the hold on our Parkinson's program in January 2023 and on Multiple System Atrophy, or MSA, in early March, 2023. As such, we are working diligently to restart the Phase 2a '201' clinical trial and have begun planning for the Phase 2 program in MSA," said Dr. Milton H. Werner, President and Chief Executive Office of Inhibikase. "We will continue making progress across our pipeline in 2023. In addition to advancing IkT-148009 in the '201' trial, we expect to complete our '501' bioequivalence study for IkT-001Pro, our prodrug formulation of imatinib mesylate for Stable-Phase Chronic Myelogenous Leukemia. We look forward to providing updates throughout the year as we seek to bring our disease-modifying therapeutics to patients living with neurodegenerative diseases and cancer."

Recent Developments and Upcoming Milestones:

• Full clinical hold on IkT-148009 in Parkinson's disease programs lifted by the U.S. Food and Drug Administration (FDA): In January 2023, Inhibikase announced that the Phase 2a '201' clinical trial for IkT-148009 would resume immediately at the 50 and 100 mg doses following the lift of the full clinical hold by the FDA. The Agency requested that the Company measure additional safety and pharmacokinetic data in healthy subjects at the 200mg dose ahead of implementation in the '201' trial, measurements that are nearing completion. In addition, the Company will broaden its ocular monitoring program to measure visual acuity and examine the cornea and lens to complement the examination of the retina, macula and fundus that was already part of the ocular monitoring program in the trial. This monitoring program is consistent with the ocular pathology monitoring programs of other approved protein kinase inhibitors. The Company is re-opening clinical trial sites and initiating screening and enrollment of patients on a rolling basis.
  
  
• Full clinical hold on IkT-148009 in MSA lifted by the U.S.FDA: In March 2023, Inhibikase announced that the Investigational New Drug (IND) application for the Phase 2 trial of IkT-148009 in MSA was lifted and the IND opened. This 6-month trial is currently in the planning stages, awaiting the outcome of prophylactic and therapeutic model studies evaluating the potential benefit of IkT-148009 as a treatment for MSA.
  
  
• Highlighted publication demonstrating the potential of IkT-148009 as a disease-modifying therapy for Parkinson's disease and related disorders: In January 2023, Inhibikase announced the publication of a paper entitled "The c-Abl inhibitor IkT-148009 suppresses neurodegeneration in mouse models of heritable and sporadic Parkinson's disease," in the Journal of Science Translational Medicine (DOI: 10.1126/scitranslmed.abp9352). The published work illustrates the neurodegenerative functional screen that led to the discovery of IkT-148009 as well as data from once daily oral administration of IkT-148009 in several animal models that mimicked the rate of disease progression observed in human PD. Results from these studies demonstrated the ability of IkT-148009 to halt disease progression, drive functional recovery and protect neurons in the brain from degradation. Therapeutic benefit in these models was accompanied by substantial reduction of alpha-synuclein pathology in the brain. These data continue to demonstrate the potential of IkT-14809 as a disease modifying therapy and support the continued clinical development of IkT-148009 in Parkinson's disease.
  
  
• Dosed first three cohorts in the '501' bioequivalence study of IkT-001Pro: In December 2022, Inhibikase announced the dosing of the first three patients in the '501' bioequivalence study of IkT-001Pro, the Company's prodrug formulation of imatinib mesylate intended to enhance the safety and efficacy of imatinib (marketed as Gleevec^®) in patients with Chronic Myelogenous Leukemia (CML). The '501' study is a single ascending dose trial and will enroll approximately 59 male and female healthy volunteers between the ages of 25 to 55 who will receive IkT-001pro at one of four single doses. Three of the four dosing cohorts in the dose escalation phase have completed the study, with the fourth escalation cohort scheduled to dose in early April 2023. The primary objective of the study is to evaluate the safety profile of IkT-001pro as well as analyze and identify a dose that mimics systemic exposure and pharmacokinetics of 400mg imatinib mesylate, the standard-of-care dose for Stable-Phase CML. The study will also evaluate the adverse event profile and patient reported outcomes as metrics of superiority over standard-of-care. Upon completion of this study, the Company intends to initiate a discussion with the FDA to discuss the parameters of drug approval under the 505(b)(2) statute.
  
  
• Successfully completed $10 million concurrent registered direct offering and private placement: In January 2023, Inhibikase raised $10 million in aggregate gross proceeds from its concurrent registered direct offering and private placement. The Company plans to use the net proceeds from the offerings for general corporate purposes, including clinical trials, product candidate development and manufacturing activities for product candidates and to meet working capital needs.

Full Year 2022 Financial Results

Grant Revenue: Grant revenue was $0.1 million for the year ended December 31, 2022 compared to $3.1 million in the prior year. The decrease was due to the Company's primary focus during 2022 being shifted toward advancing our Phase I and II clinical trials which were not submitted for grant revenue.

R&D Expenses: Research and development expenses were $12.0 million for the year ended December 31, 2022 compared to $11.4 million in the year ended December 31, 2021. The increase was primarily due to ongoing non-grant related research and development activities mostly related to the Phase 2a '201' clinical trial.

SG&A Expenses: Selling, general and administrative expenses for the year ended December 31, 2022 were $6.2 million compared to $6.5 million for the year ended December 31, 2021. The decrease was primarily the result of decreased warrant expense of $0.7 million and a decrease of stock-based compensation of $0.5 million partially offset by increased legal fees of $0.4 million, increased regulatory and compliance fees of $0.2 million and a net increase of $0.3 million for other normal operating expenses.

Net Loss: Net loss for the year ended December 31, 2022 was $18.1 million, or $0.72 per share, compared to a net loss of $14.8 million, or $0.81 per share in the year ended December 31, 2021.

Cash Position: Cash, cash equivalents and marketable securities were $23.1 million as of December 31, 2022. This excludes the net proceeds from the $10 million January 2023 concurrent registered direct offering and private placement.  The Company expects that existing cash and cash equivalents will be sufficient to fund operations into the fourth quarter of 2024.
