Amneal Pharmaceuticals, Inc. (NASDAQ: AMRX) (“Amneal” or the “Company”) today announced that it has provided a Complete Response resubmission to the U.S. Food and Drug Administration (FDA) for IPX203, a novel, oral formulation of carbidopa/levodopa (CD/LD) extended-release capsules for the treatment of Parkinson’s disease (PD).
The original NDA for IPX203 resulted in a Complete Response Letter (CRL) from FDA. The resubmission package included data from a healthy volunteer study which was conducted in the fourth quarter of 2023. The FDA did not request any other studies.
“We are pleased to provide our complete response resubmission for IPX203 as we look to expand our Parkinson’s franchise,” said Chirag and Chintu Patel, Co-Chief Executive Officers at Amneal. “We look forward to launching this much-needed treatment in the second half of 2024, subject to FDA approval.”
About IPX203
IPX203 is a novel, oral formulation of CD/LD extended-release capsules designed for the treatment of Parkinson’s disease. IPX203 contains immediate-release granules and extended-release coated beads. The IR granules consist of CD and LD, with a disintegrant polymer to allow for rapid dissolution. The ER beads consist of LD, coated with a sustained release polymer to allow for slow release of the drug a mucoadhesive polymer to keep the granules adhered to the area of absorption longer, and an enteric coating to prevent the granules from disintegrating prematurely in the stomach. This formulation is distinct from RYTARY® (carbidopa/levodopa) extended-release capsules, Amneal’s extended-release CD/LD treatment for PD approved by the U.S. FDA in 2015.
About Parkinson’s Disease
Parkinson’s disease has become the fastest growing neurological disorder worldwide, with approximately 1 million patients diagnosed in the U.S. It is a progressive disorder of the central nervous system (CNS) that affects dopamine-producing neurons in the brain that affect movement.
PD is characterized by slowness of movement, stiffness, resting tremor and impaired balance. While PD is not considered a fatal disease, it is associated with significant morbidity and disability. The average age at diagnosis for patients with PD is 60; as people live longer, the number of patients living with PD is predicted to grow significantly over the coming decades.
