Summary

This is a Phase I, investigator-initiated, first-in-human study to evaluate the safety, tolerability, and pharmacokinetics of MF1, a novel agent that is expected to inhibit α-synuclein related pathogenesis in α-synucleinopathies, primarily Parkinson's disease (PD). MF1 aims to address the unmet medical need in PD, which affects about 1% of individuals aged 60 years and older in Japan and is projected to reach 43 million patients worldwide by 2050.

The trial consists of three parts: Part A (single ascending dose) and Part B (multiple ascending dose) in healthy Japanese male adults, and Part C (multiple dose) in patients with idiopathic PD. Part A is a randomized, double-blind, placebo-controlled, single-center study assessing single oral doses , including a food-effect evaluation. Part B is a randomized, double-blind, placebo-controlled, single-center study with once-daily dosing for 7 days. Part C is an open-label, multicenter study in 4-8 PD patients (MDS 2015 criteria, Hoehn \& Yahr stage ≤3) receiving once daily for 14 days, with or without stable background antiparkinsonian therapy.

The primary objective is to assess safety and tolerability; secondary objectives include characterization of plasma, urine, and cerebrospinal fluid pharmacokinetics and assessment of food effect. Exploratory pharmacodynamic endpoints include biomarkers such as α-synuclein, neurofilament light chain, UCHL-1, FABP3, GFAP, and other neurodegeneration markers.

Key exclusion criteria include clinically significant systemic diseases, seizure history, serious infections (HBV, HCV, HIV, syphilis), recent suicidal ideation or attempts, and recent use of other investigational products.
