About RYTARYTM (IPX066)

RYTARY is an investigational extended-release capsule formulation of carbidopa-levodopa for the treatment of idiopathic Parkinson’s disease. It is not approved or licensed anywhere in the world. Results from the phase III studies of RYTARY, APEX-PD (early PD), ADVANCE-PD (advanced PD) and ASCEND-PD (advanced PD) have previously been announced.

On January 21, 2013, Impax received a complete response letter which indicated that the FDA could not approve the NDA at that time. The complete response letter stated that satisfactory resolution and verification of the deficiencies identified during the inspection of the manufacturing facility in Hayward California would be required before the NDA for IPX066 may be approved. On March 4, 2013, the Company announced the receipt of a Form 483 following an inspection by the FDA of the Hayward facility. The Form 483 contained several observations specific to IPX066 which the Company believes must be satisfactorily resolved before the NDA for IPX066 may be approved.

RYTARY has been licensed to GlaxoSmithKline (GSK) for countries outside the U.S. and Taiwan for registration and commercialization.

Impax Pharmaceuticals and GSK announced an agreement for the development and commercialization of IPX066 in December 2010. Under the terms of the agreement, GSK received an exclusive license to register and commercialize IPX066 throughout the world except in the U.S. and Taiwan.
