Overview
Brief Summary
A cardiac safety study of an investigational drug to see how it affects the heart in people with Parkinson's Disease Complicated by Motor Fluctuations ("OFF" Episodes)
Detailed Description
This multi-center, Phase 2, Randomized, Double-Blind, Placebo Controlled, 3-Period Crossover, Positive Control study designed to evaluate the QT interval prolongation potential of 10 mg to 60 mg doses of APL-130277 compared to placebo and the positive control, 400mg moxifloxacin in subjects with Parkinson's Disease (PD) who experience motor fluctuations ("OFF" episodes) The patient is titrated to the highest tolerated dose from 10mg to 60mg, and then is randomized to one of six crossover sequences. Each sequence includes treatment with the following: 1. Treatment A: APL-130277 at the dose determined in the Dose Titration Phase, 2. Treatment B: Matched placebo, 3. Treatment C: A single 400 mg dose of moxifloxacin

Eligibility Criteria
Inclusion Criteria
- •Male or female ≥ 18 years of age. 2) Clinical diagnosis of Idiopathic PD, consistent with UK Brain Bank Criteria (excluding the "more than one affected relative" criterion).

Outcomes
Primary Outcomes
Time-Matched Change From Baseline in QTc, Placebo-Adjusted and Corrected for Heart Rate Based on the Fridericia Correction Method (QTcF) Using Delta Delta Method (ΔΔQTcF): Comparison Between APL-130277 and Placebo (Central Tendency Analysis)
Time Frame: Baseline to 15, 30, 45, 60 mins and 2, 3, and 4 hours post-dose for each of the 3 treatment period dosing visits.
For the primary central tendency analysis, the changes from baseline (ΔQTcF) were compared between APL-130277 and placebo (ΔΔQTcF). Baseline was defined as the mean of the 9 ECGs (3 sets of triplicate ECGs) recorded at baseline (P1V1). In case any of the 9 ECGs were missing, the baseline was defined as the mean of the available baseline values. The post-dose ECGs were evaluated at 15, 30, 45 and 60 minutes (mins) and 2, 3 and 4 hours post-dose at each of the 3 treatment period dosing visits during the Randomized Crossover Assessment Phase. For each of the time points, an average value was calculated based on the 3 (or all available) ECGs. These average values were used in all change from baseline calculations.
Time-Matched Change From Baseline in QTc, Placebo-Adjusted and Corrected for Heart Rate Based on QTcF Using ΔΔQTcF: Comparison Between Moxifloxacin and Placebo (Assay Sensitivity Analysis)
Time Frame: Baseline to 60 mins and 2, 3, and 4 hours post-dose for each of the 3 treatment period dosing visits.
For the assay sensitivity analysis in support of the primary central tendency analysis, the changes from baseline (ΔQTcF) were compared between moxifloxacin (positive control) and placebo (ΔΔQTcF). Baseline was defined as the mean of the 9 ECGs (3 sets of triplicate ECGs) recorded at baseline (P1V1). In case any of the 9 ECGs were missing, the baseline was defined as the mean of the available baseline values. The post-dose ECGs were evaluated at 60 mins and 2, 3 and 4 hours post-dose for each of the 3 treatment period dosing visits in the Randomized Crossover Assessment Phase. For each of the time points, an average value was calculated based on the 3 (or all available) ECGs. These average values were used in all change from baseline calculations.
