Abstract: Disclosed is a method for the treatment of a neurological or movement disorder, e.g., Parkinson's disease, in an individual in need thereof, by parenteral administration of levodopa, a levodopa salt, a levodopa prodrug, or any combination thereof, and a dopa decarboxylase inhibitor (DDCI), such as carbidopa, a carbidopa salt, a carbidopa prodrug, benserazide or any combination thereof, concomitantly with oral administration of levodopa, a DDCI, such as carbidopa, benserazide, or any combination thereof.

Abstract: An improved device delivers a fluid medicament to the subcutaneous tissue of a user. The device is better suited for patients with Parkinson's Disease and other central nervous system disorders, than conventional infusion devices. The device can include a reusable part including a drive component (e.g., motor) and control electronics and a disposable part including a medicament reservoir. Medicament can be evacuated from the medicament reservoir by a plunger assembly that includes a plunger attached to a lead screw that is rotated by a nut, all within the disposable part. The device can be fluidically coupled with the tissue via a flexible cannula. Various embodiments relate to an improved cannula insertion mechanism that delivers the cannula under a force applied by a spring. Various embodiments relate to improved filling of the device, for example, using a vial adapter and an automated filling station.
