|Parkinson's Disease||Drug: VR040/Aspirair® inhaler Drug: placebo||Phase 2|
Background: 'Off' periods increase as Parkinson's disease progresses and the benefits of standard therapy wane. Subcutaneous apomorphine rescues 'off' periods, but patient self-injection and adverse cutaneous effects are sometimes problematic.
Methods: We assessed safety, tolerability and efficacy of inhaled dry powder apomorphine (VR040) in a clinic-based Phase II study. Of 48 patients recruited at 9 sites, 47 were randomized 2:1 inhaled apomorphine:placebo. Respirable doses (drug predicted to reach the lung) ascending through 1.5mg, 2.3mg, 3.0mg, and 4.0mg until efficacy was achieved, were administered to patients in a practically defined 'off' state. The primary endpoint was the response in unified Parkinson's disease rating scale Part 3 (UPDRS 3), at the highest dose received by the patient. Secondary endpoints included time to 'on', the proportion of patients converting from 'off' to 'on', and pharmacokinetics.

Active Comparator: VR040/Aspirair® inhaler
VR040 was administered as an inhaled dry powder, in a dosage of 1.5, 2.3, 3.0 and 4.0mg, single dose given at each dose level.
Drug: VR040/Aspirair® inhaler
Dry Powder inhaled apomorphine
Other Name: Inhaled apomorphine
Placebo Comparator: Placebo
Placebo was administered as an inhaled dry powder, matching to active comparator at dosages of 1.5, 2.3, 3.0 and 4.0mg, single dose given at each dose level.
- The maximum UPDRS 3 improvement from pre-dose to post-dose [ Time Frame: 90 minutes ]The primary efficacy endpoint was the maximum UPDRS 3 improvement from pre-dose to post-dose at the highest dose used.
- Time to improvement from 'off' to 'on' [ Time Frame: 90 minutes ]Time to improvement from 'off' to 'on'.
- The duration of 'on' [ Time Frame: 90 minutes ]The duration of 'on', the duration of time when the patient can function well.
- The proportion of patients converting to 'on' any time after treatment administration. [ Time Frame: 90 minutes ]The proportion of patients converting to 'on' any time after treatment administration.
- Safety variables [ Time Frame: 90minutes ]Safety variables were: the pre- to post-dose change in vital signs, 12-lead ECG and continuous 12-lead Holter ECG, and lung function.
