FDA Lifts Hold on Inhibikase Parkinson’s Trial
FDA has lifted its 11/2022 full clinical hold on the clinical trial of Inhibikase Therapeutics’ Phase 2a IkT 148-009 trial in Parkinson’s disease. The company’s multiple systems atrophy program using 148-009 remains under a hold.
The company says IkT-148009 is a c-Abl tyrosine kinase inhibitor that has been shown to halt disease progression, protect and restore lost neurons, and clear the underlying protein pathology in animal studies that suggest a causal link to the initiation and progression of disease in humans.
Inhibikase says the FDA decision to lift the hold on the Parkinson’s program was based on the company’s response and commitments made regarding ophthalmologic monitoring in the study and modifications to the investigator brochure.
FDA asked the company to measure the safety and steady-state pharmacokinetic profile of the 200 mg dose in six healthy people before administration of that dose in Parkinson’s patients. The agency also asked for the measurement of visual acuity and examination of the cornea and lens to complement the analysis of retina, macula, and fundus that was already part of the ocular monitoring program in the trial that was under hold.
Inhibikase says it plans to ask FDA to lift the hold on the multiple systems atrophy program.
