- New tablet formulation of risvodetinib approximately doubles drug exposure at same dose –

- Tablet formulation to be evaluated in the planned 12-month extension portion of the 201 trial–

BOSTON and ATLANTA, Aug. 24, 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 announced that it has developed a novel tablet formulation of IkT-148009, designed to improve drug exposure and overcome existing challenges related to patient use.

"As we advance our 201 trial evaluating risvodetinib at 50, 100 and 200 mg to treat Parkinson's disease, we have continued to expand our formulation and delivery capabilities," commented Dr. Milton Werner, President & CEO of Inhibikase. "We recently completed characterization of a novel tablet formulation that mimics the oral formulation we used to evaluate efficacy in validated animal models of Parkinson's disease. This novel tablet formulation nearly doubles drug exposure at steady-state for the same dose of risvodetinib, potentially enabling us to use a lower dose to reach therapeutic efficacy.  This could improve the overall safety and tolerability of risvodetinib. In addition, the smaller size of these tablets compared to the capsules currently in use in the 201 clinical trial, the smaller tablets may overcome challenges patients have swallowing oral medication as a result of their disease. This new tablet formulation would be implemented in the planned 12 month extension of the 201 trial."

Inhibikase's multi-therapeutic pipeline has a primary focus on neurodegeneration and its lead program IkT-148009, 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 Ableson Tyrosine Kinases.
