Publication number: 20140193507Abstract: Injectable compositions having improved injectability. The injectable compositions include microparticles suspended in an aqueous injection vehicle having a viscosity of at least 20 cp at 20° C. The increased viscosity of the injection vehicle that constitutes the fluid phase of the suspension significantly reduces in vivo injectability failures. The injectable compositions can be made by mixing dry microparticles with an aqueous injection vehicle to form a suspension, and then mixing the suspension with a viscosity enhancing agent to increase the viscosity of the fluid phase of the suspension to the desired level for improved injectability.Type: ApplicationFiled: November 20, 2013Publication date: July 10, 2014Applicants: Alkermes Pharma Ireland Limited, Alkermes Controlled Therapeutics, Inc.Inventors: J. Michael Ramstack, M. Gary I. Riley, Stephen E. Zale, Joyce M. Hotz, Olufunmi L. Johnson

Patent number: 5916597Abstract: Composition for the sustained release of a biologically active agent in vivo. The composition comprises microcarriers containing a first solid-phase biocompatible material and a biologically active agent, wherein said microcarriers sustain the in vivo release of the biologically active agent. The composition also contains particles of a second biocompatible solid-phase material wherein the second solid-phase material further sustains the in vivo release of the biologically active agent.The invention also relates to a method for sustaining effective serum levels of a biologically active agent in a subject, including forming an injectable dose containing an effective amount of a biologically active agent, wherein the agent is contained in a microcarrier, with a release-period sustaining amount of a solid-phase material. The method further includes administering the injectable dose to the subject.Type: GrantFiled: August 29, 1996Date of Patent: June 29, 1999Assignee: Alkermes Controlled Therapeutics, Inc.Inventors: Hye-Jung Lee, OluFunmi L.
