AbbVie to Present New Data From 18 Abstracts at the International Congress of Parkinson’s Disease and Movement Disorders®

NORTH CHICAGO, Ill., Sept. 11, 2020 /PRNewswire/ -- AbbVie (NYSE: ABBV) today announced it will present results from several studies, including the DYSCOVER study evaluating the efficacy of DUODOPA® (levodopa/carbidopa intestinal gel) on the duration and severity of dyskinesia in patients with advanced Parkinson's disease (PD), at the 2020 International Congress of Parkinson's Disease and Movement Disorders® Virtual Congress, September 12-16. In total, 18 abstracts will be presented, including an overview of the pivotal Phase 3 study design for the investigational medicine ABBV-951 in patients with advanced PD, several studies evaluating the economic burden of PD, as well new and updated data evaluating AbbVie's neuroscience portfolio and pipeline.

The 12-week DYSCOVER study is the first randomized clinical trial comparing the efficacy of DUODOPA to optimized medical treatment (OMT) on dyskinesia in advanced PD patients using the Unified Dyskinesia Rating Scale (UDysRS), which measures all aspects of dyskinesia with a comprehensive score as the primary endpoint.

The study design for the multi-country, open-label, single arm, 52-week pivotal phase 3 study of ABBV-951 (foscarbidopa/foslevodopa), a subcutaneous delivery of levodopa/carbidopa being investigated for the treatment of advanced PD, will also be presented. The study is evaluating the local and systemic safety and tolerability of ABBV-951 delivered as a continuous, all-day subcutaneous infusion via an external pump for up to 52 weeks in people with advanced PD. The study is in process and estimated to conclude in late 2021.

"At AbbVie, we are resolute in our commitment to address the unmet needs of people living with neurologic diseases through new and innovative solutions," said Michael Gold, MD, Vice President, Neuroscience Development. "In the face of uncertainty and the unknown, we are determined to preserve personhood. We look forward to participating in the MDS 2020 Virtual Congress and sharing our latest research with scientists and healthcare professionals from around the globe."

Other data presentations include analyses from several DUODOPA-related studies, including the COSMOS Observational Study, a multi-country, cross-sectional, retrospective, post-marketing observational study that enrolled patients with advanced PD who were treated with DUODOPA for more than 12 months. Also being presented are analyses from the DUOGLOBE study, a three-year global, multicenter, single-arm, non-interventional post-marketing observational study of patients with advanced PD treated with DUODOPA.

Additionally, abstracts demonstrating the prevalence, impact and economic burden of PD will be presented. 

About Parkinson's Disease 
More than 10 million people worldwide are living with Parkinson's disease¹, a progressive and chronic movement disorder characterized by tremor, muscle rigidity, slowness of movement and difficulty with balance.² It is classified as a movement disorder resulting from the loss of dopamine-producing brain cells.³ The motor symptoms of Parkinson's disease begin when approximately 60-80 percent of the dopamine-producing cells in the brain are lost and symptoms continue to worsen slowly over the course of time.⁴ While there is no known cure for the disease, there are treatments available to help reduce symptoms.⁵

As Parkinson's disease progresses, patients can experience fluctuations from an "on state" to an "off state," during which they are slower and stiffer and experience more difficulty moving. Patients can also experience dyskinesias (involuntary movements). Dyskinesia is among the most troublesome symptoms of the disease with approximately 50 percent of patients presenting with dyskinesia four to five years after initiation of treatment and approximately 90 percent of patients presenting with dyskinesia after nine years.⁶

DUODOPA® (levodopa/carbidopa intestinal gel) EU Indication
DUODOPA is indicated for the treatment of advanced levodopa-responsive Parkinson's disease with severe motor fluctuations and hyperkinesia or dyskinesia when available combinations of Parkinson's medicinal products have not given satisfactory results.

Important DUODOPA EU Safety Information
DUODOPA is contraindicated in patients with hypersensitivity to levodopa, carbidopa or any of the excipients, narrow-angle glaucoma, severe heart failure, severe cardiac arrhythmia, acute stroke, selective type A inhibitors and nonselective MAO inhibitors, conditions contraindicated for adrenergics (e.g. pheochromocytoma, hyperthyroidism, and Cushing's syndrome), and suspicious skin lesions or history of melanoma.

Some warnings and precautions include the following: device and procedure-related complications, sudden onset of sleep: caution should be exercised when driving and operating machines. Caution in: severe cardiovascular or pulmonary disease, bronchial asthma, renal, hepatic or endocrine disease, or history of peptic ulcer disease or of convulsions. Risk of symptoms resembling Neuroleptic Malignant Syndrome following abrupt dose reduction or discontinuation. Monitor all patients for the development of mental changes, depression with suicidal tendencies, and other serious mental changes. Caution in chronic wide-angle glaucoma; monitor for intra-ocular pressure changes. Patients with past or current psychosis should be treated with caution. Monitor patients regularly for the development of impulse control disorders, for example Dopamine Dysregulation Syndrome (DDS). Periodic evaluation of hepatic, haematopoietic, cardiovascular and renal function is recommended during extended therapy with DUODOPA. Patients with Parkinson's disease have a higher risk of developing melanoma. Monitor patients for melanomas on a regular basis when using DUODOPA. DUODOPA is not recommended during pregnancy. Breast-feeding should be discontinued during treatment with DUODOPA.

The most common adverse reaction was complication of device insertion.

The very common (≥ 10%) and common  (≥1% to < 10%) device and procedure-related adverse reactions reported in clinical trials included abdominal discomfort, abdominal pain, peritonitis, pneumoperitoneum postoperative wound infection, incisional cellulitis, excessive granulation tissue, device dislocation, device occlusion, complications of device insertion, incision site erythema, post-procedural discharge, stoma complication, incision site pain, postoperative Ileus, post-procedural complication, post-procedural discomfort and post-procedural hemorrhage.

Most of these adverse reactions were reported early in the studies, subsequent to the percutaneous endoscopic gastrostomy procedure, occurring during the first 28 days.

Drug-related undesirable effects that occur frequently with the DUODOPA system include nausea and dyskinesia.
