Abstract: The present disclosure is directed to formulations, devices, kits, and methods for treating or preventing motor symptoms associated with Parkinson's disease by injection of a microsphere formulation of apomorphine free base or a pharmaceutically acceptable a salt thereof, wherein injection can be from a pre-filled injector.

Abstract: The invention is directed to a biodegradable, phase separated, thermoplastic multi-block copolymer, to a process for preparing a biodegradable, phase separated, thermoplastic multi-block copolymer, to the use of a biodegradable, semi-crystalline, phase separated, thermoplastic multi-block copolymer, and to a composition for the delivery of at least one biologically active compound to a host. The biodegradable, phase separated, thermoplastic multi-block copolymer of the invention comprises at least one amorphous hydrolysable pre-polymer (A) segment and at least one semi-crystalline hydrolysable pre-polymer (B) segment, wherein said multi-block copolymer under physiological conditions has a Tg of 37° C. or less and a Tm of 50-110° C.
