Safety and effectiveness of rasagiline in patients with Parkinson's disease in Japan: a post-marketing surveillance study

BackgroundRasagiline is a monoamine oxidase B inhibitor for the treatment of Parkinson's disease (PD). This study assessed the safety and effectiveness of rasagiline in patients with PD in routine clinical practice in Japan.Research design and methodsThis multicenter, prospective, observational study (148 sites) enrolled patients (1 November 2018-31 October 2020) with PD. Patients received rasagiline orally 1 mg once daily; maximum observation period was 24 months. The incidence of adverse drug reactions (ADRs) was evaluated; effectiveness was assessed using the Unified Parkinson's Disease Rating Scale (UPDRS) Part III total score.ResultsThe safety analysis set comprised 961 patients (mean age, 72.50 years; 53.80% female; mean duration of PD, 6.82 years). Mean treatment duration was 14.74 months, with 42.25% receiving rasagiline for >= 19 months; 189 (19.67%) had >= 1 ADR. Common ADRs were dyskinesia (4.06%), orthostatic hypotension (2.29%), hallucination (1.87%), visual hallucination, nausea, fall (1.56% each), dizziness (1.35%), and somnolence (1.25%). Mean (standard deviation) UPDRS Part III total score was 28.5 (14.35) at baseline and 25.5 (14.98) at the final assessment.ConclusionsNo new concerns in safety and effectiveness regarding rasagiline in Japanese patients with PD were raised.Trial registrationClinicalTrials.gov: NCT03727139; Japan Pharmaceutical Information Center Clinical Trials Information: JapicCTI-184181.
