AMSTERDAM, Sept. 25, 2015 /PRNewswire/ -- Impax Laboratories, Inc. (NASDAQ: IPXL) today announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency has adopted a positive opinion recommending that NUMIENT (IPX066), a modified-release oral capsule formulation of levodopa-carbidopa, be granted approval for the symptomatic treatment of adult patients with Parkinson's disease. The European Commission (EC) will now consider the CHMP positive opinion in its decision of whether to grant marketing authorization for NUMIENT in Europe. The review of this application is being conducted under the centralized licensing procedure as a therapeutic innovation, and the final decision will be applicable in all 28 member states of the European Union, as well as Iceland, Liechtenstein and Norway.
"The positive opinion from the CHMP recommending the approval of NUMIENT is a significant step forward to providing a new treatment option to patients in Europe suffering from Parkinson's disease," said Fred Wilkinson, President and Chief Executive Officer of Impax. "We are committed to realizing the full potential of this important franchise and we look forward to the European Commission's decision in the coming months."
"We continue to have discussions with potential partners to help commercialize NUMIENT in Europe. If approved, we will work quickly to bring NUMIENT to patients," concluded Mr. Wilkinson.
The CHMP's positive opinion is based on results from three Phase 3 controlled clinical studies which assessed the safety and efficacy of NUMIENT in patients with early (levodopa-naive) and advanced Parkinson's disease in the U.S. and in Europe. Refer to the "Summary of the Three Phase 3 Controlled Clinical Studies" for additional information.
About Parkinson's disease Parkinson's disease is a chronic neurodegenerative movement disorder affecting approximately 7 to 10 million people globally. There is currently no known cure for Parkinson's disease.
About NUMIENT If approved in Europe, NUMIENT will be indicated for the symptomatic treatment of adult patients with Parkinson's disease. NUMIENT is not for use in patients with hypersensitivity to the active drug substances or excipients in NUMIENT, narrow-angle glaucoma, phaeochromocytoma, a previous history of neuroleptic malignant syndrome (NMS) and/or non-traumatic rhabdomyolysis, or in patients using nonselective monoamine oxidase inhibitors (MAO) inhibitors, which must be discontinued 2 weeks prior to starting to use NUMIENT.
Summary of the Three Phase 3 Controlled Clinical Studies In APEX-PD, a trial that enrolled and randomized 381 levodopa-naive patients, the study met its primary efficacy endpoint of mean change from baseline in the sum of Unified Parkinson's Disease Rating Scale (UPDRS) Part II (activities of daily living) score and UPDRS Part III (motor examination) score for NUMIENT versus placebo at end of study.
In ADVANCE-PD, a trial of 393 randomized patients with advanced Parkinson's disease having "off" time, the results showed treatment with IPX066 (NUMIENT) reduced the percentage of "off" time (36.9% to 23.8%) from baseline versus immediate-release levodopa-carbidopa (36.0% to 29.8%) during waking hours to end of study, representing almost 1.2 hours of additional "off" time improvement. IPX066 (NUMIENT) also increased "on" time without troublesome dyskinesia during waking hours by 1.9 hours compared with an increase of 0.8 hours following treatment with immediate-release levodopa-carbidopa. Less "off" time was primarily related to more "on" time without troublesome dyskinesia.
In ASCEND-PD, a trial of 91 randomized patients with advanced Parkinson's disease having "off" time, compared IPX066 versus levodopa-carbidopa plus entacapone (LCE). Patients entered the study with a baseline "off" time of 36.1% (5.9 hours), and at the end of the randomized IPX066 treatment phase, patients had "off" time of 24.0% (3.8 hours) during waking hours compared to 32.5% (5.2 hours) for LCE (p<0.0001), representing 1.4 hours of additional "off" time improvement.
Summary of the NUMIENT Safety Profile The most frequently reported adverse reactions in the 978 patients exposed to NUMIENT during the entire clinical program were nausea, occurring in approximately 12% of all patients; dizziness, headache, and dyskinesia, each occurring in approximately 8% of all patients; and insomnia, occurring in approximately 6% of all patients. Serious events of gastrointestinal haemorrhage (uncommon) and of allergic oedema (uncommon) were reported in the clinical studies with NUMIENT.
