Acorda Therapeutics, Inc.(Nasdaq:ACOR) today presented data from a Phase 2b clinical trial of CVT-301, an inhaled levodopa (L-dopa) under development for the episodic treatment of OFF episodes associated with Parkinson's disease (PD). OFF episodes are characterized by a re-emergence of PD motor symptoms, such as impaired ability to move, muscle stiffness and tremor. The trial showed that patients experiencing an OFF episode, treated with CVT-301, showed significantly greater improvements in motor function than patients treated with inhaled placebo; the difference in improvement was already apparent 10 minutes after dosing and was durable for at least an hour, the longest time point at which patients were measured. These data were presented at the 19th
"Oral levodopa, or L-dopa, is the current gold standard of care for Parkinson's disease. However, as the disease progresses, the majority of people will experience OFF episodes, even while on L-dopa therapy," said
The Phase 2b trial was a randomized, double blind, placebo-controlled, multicenter study in 86 people with PD for the treatment of OFF episodes. Participants were randomized to self-administer CVT-301 or placebo as an adjunct to oral PD medications. Participants received 35mg of CVT-301 or placebo delivered to the lung in weeks 1 and 2, and 50mg of drug or placebo delivered to the lung in weeks 3 and 4. In-office assessments of the Unified Parkinson's Disease Rating Scale Part 3 (UPDRS III) were performed at weeks 1, 2 and 4. The primary endpoint was defined as the mean change from baseline in UPDRS III score (10-60 minutes post dose) after 4 weeks of treatment. UPDRS III is an established scale to monitor PD motor impairment, and is considered a standard in the field.
In this study, participants receiving CVT-301 showed a statistically significant and clinically important reduction in average UPDRS III motor score compared to placebo (p<0.01) and across all measured time points beginning at 10 and up to 60 minutes post-administration (p < 0.05). Both doses of CVT-301 were well tolerated, with no increase relative to placebo in troublesome or non-troublesome dyskinesias during ON periods. There were no serious adverse events reported in the drug group, and the incidence of drug-related adverse events was similar between treatment groups. The most common adverse events were dizziness, headache and cough; there were no adverse events on cardiovascular or lung function. PD patients were able to self-administer treatment while in an OFF state.
"OFF episodes have a major negative impact on the lives of people with Parkinson's disease, as well as on their loved ones and care partners. Effective treatment options are desperately needed," said
The poster was chosen by the MDS Congress Scientific Program Chairs for a Guided Poster Tour Presentation. The poster is also under consideration for inclusion in the Blue Ribbon Highlights session, which will provide a critical overview of the best presentations highlighting the relevance, novelty and quality of both clinical and basic research.

About CVT-301 Phase 3 Program
Based on the results of the Phase 2b trial, Acorda has initiated a Phase 3 clinical trial that is expected to enroll approximately 345 participants across three arms: 50mg, 35mg, or placebo. These are the same doses used in the Phase 2b study. The primary outcome measure is improvement on the UPDRS III after administration of CVT-301.
