Inhibikase Therapeutics Pulls Plug on Parkinson’s Drug
Inhibikase Therapeutics says it is pausing further development of risvodetinib, a selective inhibitor of the non-receptor Abelson Tyrosine Kinases and its use in untreated Parkinson’s disease. The company says that recent data from its Phase 2 201 trial did not demonstrate an “improvement in the top hierarchical efficacy measure, which was the sum of Parts 2 and 3 of the Movement Disorder Society Universal Parkinson’s Disease Rating Scale” at any dose group (50mg, 100mg or 200mg) versus placebo.
The company noted that the 201 trial met its primary endpoint of safety and tolerability, with 95% of enrolled participants completing 12 weeks on risvodetinib. “Risvodetinib adverse event observations were comparable to placebo in frequency and severity,” it says, adding that there were no treatment-related severe adverse events.
Risvodetinib is described as an oral drug that targets c-Abl, a kinase enzyme that’s involved in Parkinson’s disease. It was intended to prevent the loss of dopamine-producing neurons in the brain and gut, which can help reverse the disease’s effects.
