• SPAN℠-PD, the efficacy and safety study of INBRIJA (CVT-301), showed significant improvement in motor function during OFF periods in people with Parkinson’s on a carbidopa/levodopa regimen
• INBRIJA was approved in the U.S. in Dec. 2018 and is expected to be available by prescription in Q1 2019

ARDSLEY, N.Y.--(BUSINESS WIRE)-- Acorda Therapeutics, Inc. (Nasdaq:ACOR) today announced that TheLancet Neurology published results from SPAN℠-PD, the Phase 3 pivotal efficacy trial of INBRIJA™ (levodopa inhalation powder), also referred to as CVT-301. In the study, INBRIJA 84 mg significantly improved motor function at 30 minutes during OFF periods in people with Parkinson’s taking carbidopa/levodopa, the study’s primary endpoint. Onset of action was seen as early as 10 minutes and the reduction at 30 minutes was maintained at 60 minutes. Multiple secondary endpoints were supportive of the primary endpoint. Data from the study were first presented at the 2017 International Congress of Parkinson’s Disease and Movement Disorders (MDS).

“A well-tolerated, effective treatment for OFF periods between doses of scheduled medications can help fulfill one of the most important unmet needs for people with Parkinson’s,” said lead author of the publication Peter LeWitt, M.D., Director of the Parkinson’s Disease and Movement Disorders Program at Henry Ford Hospital and professor of neurology at Wayne State University School of Medicine. “The data published in TheLancet Neurology support INBRIJA as such a treatment option, delivering levodopa, the current ‘gold standard’ of Parkinson’s treatment, in a novel, inhaled form.”

“We’re gratified to see the SPAN-PD trial paper published in one of the most highly regarded neurology journals, TheLancet Neurology. We believe this reflects both the quality of the study and the importance of its clinical results to people with Parkinson’s,” said Ron Cohen, M.D., Acorda’s President and CEO. “INBRIJA was recently approved by the FDA, and we are eager to make it available to the Parkinson’s community during the first quarter of 2019.”

About SPAN℠-PD ( NCT02240030 ) and Key Results

The Phase 3 pivotal efficacy trial for INBRIJA – SPAN-PD – was a 12-week, randomized, placebo controlled, double blind study evaluating the effectiveness of INBRIJA versus placebo in patients with Parkinson’s experiencing OFF periods.

The 339 patients in the trial had mild to moderate Parkinson’s and were on an oral levodopa plus a dopa-decarboxylase inhibitor (e.g., carbidopa). Most were on additional scheduled Parkinson’s medication and were experiencing at least two hours per day of OFF time. Patients with asthma, COPD, or other chronic lung disease within the previous five years were excluded. Patients were randomized into three treatment groups: 113 in the INBRIJA 60 mg group, 114 in the INBRIJA 84 mg group and 112 with placebo.

The primary endpoint was the change in the Unified Parkinson’s Disease Rating Scale (UPDRS) motor scores from pre-dose to 30 minutes post-dose, evaluated at week 12 during an in-clinic OFF period. INBRIJA 84 mg showed statistically significant improvement in motor function compared to placebo as measured by mean change in the UPDRS motor score at 30 minutes post-dose (-9.83 vs. -5.91; p=0.0088).

Key secondary endpoints for INBRIJA versus placebo also were evaluated at week 12 using a pre-specified hierarchy. The order of hierarchy was set based on probability of success, guided by a Phase 2 study. The primary endpoint (INBRIJA 84 mg vs. placebo) was tested first for statistical significance. Upon achieving significance, the secondary endpoints were tested for INBRIJA 84 mg vs. placebo as long as each preceding endpoint reached a significance level of p<0.05. The hierarchical sequence did not reach statistical significance at Step 3. Unadjusted (nominal) p-values are presented below for all key secondary endpoints.

Reported adverse events in at least 4% of patients in the INBRIJA 84 mg group vs. placebo were: cough (15% vs. 2%), upper respiratory tract infection (6% vs. 3%), nausea (5% vs. 3%), discolored sputum (5% vs. 0%) and dyskinesia (4% vs. 0%). Most adverse events of cough in the INBRIJA treatment groups started within the first 30 days of treatment, and these were generally assessed as mild or moderate in intensity. Two patients in the INBRIJA 84 mg group withdrew from the study due to cough.

About INBRIJA™ (levodopa inhalation powder)

INBRIJA is the first and only inhaled levodopa for intermittent treatment of OFF episodes in patients with Parkinson’s disease treated with carbidopa/levodopa. INBRIJA utilizes Acorda’s innovative ARCUS^® platform for inhaled therapeutics. A Marketing Authorization Application (MAA) for INBRIJA was submitted to the European Medicines Agency (EMA) in March 2018 and was formally validated in May 2018.

Important Safety Information

INBRIJA is not to be used if patients take or have taken a nonselective monoamine oxidase inhibitor such as phenelzine or tranylcypromine within the last 2 weeks.

Before using INBRIJA, patients should tell their healthcare provider about all their medical conditions, including:

• asthma, chronic obstructive pulmonary disease (COPD), or any chronic lung disease
• daytime sleepiness from a sleep disorder or if they get drowsy/sleepy without warning or take a medicine that increases sleepiness such as sleep medicines, antidepressants, or antipsychotics
• feel dizzy, nausea, sweaty, or faint when standing from sitting/lying down
• history of abnormal movement (dyskinesia)
• mental health problem such as hallucinations or psychosis
• uncontrollable urges (for example, gambling, increased sexual urges, intense urges to spend money, or binge eating)
• glaucoma
• pregnancy or plans to become pregnant. It is not known if INBRIJA will harm an unborn baby.
• breastfeeding or plans to breastfeed. Levodopa (the medicine in INBRIJA) can pass into breastmilk and it is unknown if it can harm the baby.

Patients should tell their healthcare provider if they take:

• MAO-B inhibitors
• dopamine D2 receptor antagonists (including phenothiazines, butyrophenones, risperidone, metoclopramide), or isoniazid
• iron salts or multivitamins that contain iron salts

No more than 1 dose (2 capsules) should be taken for any OFF period. No more than 5 doses (10 capsules) of INBRIJA should be taken in a day.

INBRIJA is for oral inhalation only. INBRIJA capsules are not to be swallowed or opened.

Patients are not to drive, operate machinery, or do other activities until they know how INBRIJA affects them. Sleepiness and falling asleep suddenly can happen as late as a year after treatment is started.

INBRIJA can cause serious side effects including the following. Patients should tell their healthcare provider if they experience them:

• falling asleep during normal daily activities (such as driving, doing physical tasks, using hazardous machinery, talking, or eating) which can be without warning. If patients become drowsy while using INBRIJA, they should not drive or do activities where they need to be alert. Chances of falling asleep during normal activities increases if patients take medicines that cause sleepiness.
• withdrawal-emergent hyperpyrexia and confusion (symptoms including fever, confusion, stiff muscles, and changes in breathing and heartbeat) in patients who suddenly lower or change their dose or stop using INBRIJA or carbidopa/levodopa medicines.
• low blood pressure with or without dizziness, fainting, nausea, and sweating. Patients should get up slowly after sitting or lying down.
• hallucinations and other psychosis – INBRIJA may cause or worsen psychotic symptoms including hallucinations (seeing/hearing things that are not real); confusion, disorientation, or disorganized thinking; trouble sleeping; dreaming a lot; being overly suspicious or feeling people want to harm them; believing things that are not real, acting aggressive, and feeling agitated/restless.
• unusual uncontrollable urges such as gambling, binge eating, shopping, and sexual urges has occurred in some people using medicines like INBRIJA.
• uncontrolled, sudden body movements (dyskinesia) may be caused or worsened by INBRIJA. INBRIJA may need to be stopped or other Parkinson’s medicines may need to be changed.
• bronchospasm – people with asthma, COPD, or other lung diseases may wheeze or have difficulty breathing after inhaling INBRIJA. If patients have these symptoms, they should stop taking INBRIJA and call their healthcare provider or go to the nearest hospital emergency room right away.
• increased eye pressure in patients with glaucoma. Healthcare providers should monitor this.
• changes in certain lab values including liver tests

The most common side effects of INBRIJA include cough, upper respiratory tract infection, nausea, and change in the color of saliva or spit.

About Parkinson’s and OFF periods

Parkinson’s is a progressive neurodegenerative disorder resulting from the gradual loss of certain neurons. These neurons are responsible for producing dopamine and that loss causes a range of symptoms including impaired movement, muscle stiffness and tremors As Parkinson’s progresses, people are likely to experience OFF periods, which are characterized by the return of Parkinson’s symptoms, which can occur despite underlying baseline therapy. Approximately one million people in the U.S. and 1.2 million Europeans are diagnosed with Parkinson’s; it is estimated that approximately 40 percent of people with Parkinson’s in the U.S. experience OFF periods.
