90 subjects randomized in comparative trial of IPX066 to carbidopa-levodopa and entacapone Jul 26, 2011 (BUSINESS WIRE) Impax Pharmaceuticals, the branded products division of Impax Laboratories, Inc. /quotes/zigman/81476/quotes/nls/ipxl IPXL +0.64% , today announced that it has completed enrollment in the ASCEND-PD trial. ASCEND-PD is a multinational Phase III comparative study of IPX066 to carbidopa-levodopa and entacapone in subjects with advanced Parkinson's disease (PD). IPX066 is an investigational extended release capsule formulation of carbidopa-levodopa (CD-LD) intended to treat the motor symptoms of Parkinson's disease. IPX066 is being developed in collaboration with GlaxoSmithKline (GSK) outside the US and Taiwan. "We are extremely pleased to have completed enrollment in ASCEND-PD, which is the third Phase III trial of IPX066 in PD subjects," stated Suneel Gupta, chief scientific officer of Impax Pharmaceuticals. "The study compares IPX066 to another commonly used medication in advanced PD, and is intended to provide further safety and efficacy data on IPX066." Impax plans to provide the top line results for this trial in late August of this year and continues to progress toward filing the new drug application in the fourth quarter of 2011.
About the ASCEND-PD Study The ASCEND-PD study is a supportive Phase III study to compare the efficacy and safety of IPX066 to Carbidopa-Levodopa and Entacapone (CLE,) in subjects with advanced Parkinson's disease. The trial is randomized, double-blind 2-treatment, 2-period crossover study of IPX066 and CLE. Study subjects currently taking a stable dose of CLE were enrolled into a six-week conversion onto IPX066 and then randomized to one of the two treatments for two weeks and then crossed over to the other for an additional two weeks. The study enrolled 110 subjects, with 90 subjects entering the randomized comparative phase of the study. The primary efficacy parameter is the percent "off time" during waking hours based on the subject PD diaries. Following the comparative phase, subjects were able to enroll in a six-month open-label extension phase.
About IPX066 IPX066 is an investigational extended release capsule formulation of CD-LD with an enhanced pharmacokinetic profile. The IPX066 pharmacokinetic profile has the potential to offer reliable control of PD motor symptoms. Impax Pharmaceuticals has previously announced the successful completion of two pivotal phase III trials in advanced PD subjects (ADVANCE-PD) and in early PD patients (APEX-PD). Open-label extension studies for subjects who have completed the ADVANCE-PD, APEX-PD, and ASCEND-PD studies are also ongoing. The Company plans to file a New Drug Application for IPX066 in PD in the fourth quarter of 2011.
