Civitas Therapeutics, INC CVT-301-005
Protocol CVT-301-005: A Phase 3, Randomized Study Investigating the Safety of CVT-301 (Levodopa Inhalation Powder) in Parkinson’s Disease Patients With Motor Response Fluctuations (OFF Phenomena) Compared to an Observational Cohort Control Patient has idiopathic PD (i.e., not induced by drugs or other diseases) as defined by fulfilling Steps 1 and 2 of the UK Brain Bank criteria, diagnosed after the age of 30 years. Patient is classified as Stage 1 to 3 (in the ON state) on the modified Hoehn and Yahr scale for staging of PD severity. Patient has experienced motor fluctuations for a minimum of 2 hours of average daily OFF time per waking day (excluding early morning OFF time) by self-report and confirmed by the PD Diary (on 3 consecutive days) during the screening period. Patient must be stable on oral LD-containing therapy for at least 2 weeks prior to SV1 with a LD/dopamine decarboxylase inhibitor (DDI)-containing regimen, which must include doses at least 4 times during the waking day and a total daily LD dose of ≤1600 mg (exclusive of PRN LD-containing medications). Patient must be able to perform a spirometry maneuver in the ON and OFF states, and must have a screening FEV1 ≥50% of predicted and an FEV1/FVC ratio >60% in the ON state at screening. Participations would last about 12 months. Enrolled patients may be compensated for travel and meals
