Gothenburg, Sweden, February 27, 2025 - IRLAB Therapeutics AB (Nasdaq Stockholm: IRLAB A), a company that discovers and develops new treatments for Parkinson's disease, today announces that data from the company’s Phase IIb study of mesdopetam has been published in Movement Disorders Clinical Practice. The publication in this prestigious, peer-reviewed medical journal further validates the integrity and clinical importance of the study results, which support the primary efficacy parameter and dose level selected for the upcoming Phase III program.
The data analyses showed clinically meaningful and dose-dependent anti-dyskinetic effects of mesdopetam, although the primary efficacy endpoint, good ON-time, was not met in this Phase IIb study. Several secondary evaluations for ON-phase dyskinesia, including the Unified Dyskinesia Rating Scale (UDysRS), showed clinically relevant and statistically significant improvement. Patients randomized to the highest dose, 7.5 mg twice daily, showed a high UDysRS response rate with 71.4% of the subjects achieving clinically relevant improvement.
Furthermore, evaluation of OFF time showed a dose-dependent decrease, with the most substantial efficacy noted for the 7.5 mg dose, indicating that mesdopetam also may have antiparkinsonian efficacy.
Overall, treatment with mesdopetam was safe and well tolerated, with an adverse event profile similar to placebo.
“We are pleased that Movement Disorders Clinical Practice has accepted the publication of our Phase IIb data on mesdopetam. The results provide a strong foundation for the design of the upcoming Phase III program, where UDysRS will be used to evaluate mesdopetam at a daily dose of 7.5 mg twice daily.,” says Susanna Waters, Director of Systems Pharmacology at IRLAB.
The randomized, double-blind, placebo-controlled Phase IIb study of mesdopetam evaluated the efficacy, safety, and optimal dose of the drug candidate in people with PD-LIDs. The study randomized 156 patients into four groups: three dose levels (2.5, 5 and 7.5 mg) of mesdopetam and a placebo group. Approximately 40 patients were included in each group, and the treatment period was three months. The study was conducted at 46 study sites in Europe, Israel, and the US. Top-line data from the study were first announced in February 2023.
The article, titled Mesdopetam for the treatment of levodopa induced dyskinesia in Parkinson disease: A randomized Phase 2b trial, is written by Angelo Antonini et. al.
