Session Title: Parkinson’s Disease: Clinical Trials, Pharmacology And Treatment
Session Time: 1:15pm-2:45pm
Location: Exhibit Hall C
Objective:
To determine if baseline disease severity could be correlated to the effective dose of APL-130277 that was required to turn a patient with PD from OFF to fully ON.
Background:
Patients with PD frequently develop problematic OFF episodes despite optimization of therapies. APL-130277 (apomorphine) is administered sublingually and being studied for OFF episodes.
Methods:
The open-label dose titration phase (DTP) was conducted to determine the appropriate dose of APL-130277 for each patient in the double-blind, placebo-controlled maintenance treatment phase (MTP). The titration sequence for APL-130277 was 10mg, 15mg, 20mg, 25mg, 30mg and 35 mg. Patients who responded with a full ON within 45 mins could move to the MTP. Patients who did not achieve a full ON returned to the clinic for the next dose. The process was repeated until patients achieved a full ON within 45 mins or reached 35mg. We evaluated if disease severity (assessed via the baseline levodopa dose, the mean number of OFF episodes per day, the Hoehn & Yahr [H & Y] scale score in the ON state, or the MDS-UPDRS Part III score in the OFF state) was correlated with the APL-130277 dose required to turn a patient with PD from OFF to fully ON.
Results:
Preliminary safety data is available for the 76 patients. Thirty-seven patients (49%) turned fully ON at the 10mg dose, 12 (16%) at 15mg, 10 (13%) at 20mg, 4 (5%) at 25mg, 11 (14%) at 30mg and 2 (3%) at 35mg. There was no correlation with baseline levodopa dose (R2=0.0759), the mean number of OFF episodes per day (R2=0.0095), H & Y in the ON state (R2=0.0023), or the MDS-UPDRS Part III score (R2=0.0007) and the dose that turned patients to a full ON.
Conclusions:
In this analysis, the APL-130277 dose that turned patients from OFF to fully ON was not correlated with disease severity.
