Preparation of extended shelf-life biodegradable, biocompatible microparticles containing a biologically active agent
Patent 5,792,477
Issued: August 11, 1998
Inventor(s): Rickey; Michael E. & Ramstack; J. Michael & Lewis; Danny H. & Mesens; Jean
Assignee(s): Alkermes Controlled Therapeutics, Inc. II
Janssen Pharmaceutica
A method for preparing biodegradable, biocompatible microparticles. A first phase is prepared that includes a biodegradable, biocompatible polymeric encapsulating binder, and an active agent having limited water solubility dissolved or dispersed in a solvent. An aqueous second phase is prepared. The first and second phases are combined to form an emulsion in which the first phase is discontinuous and the second phase is continuous. The two phases are separated. The discontinuous first phase is washed with water, or an aqueous solution of water and a solvent for residual solvent in the first phase, to reduce the level of residual solvent in the microparticles to less than about 2% by weight of the microparticles. Also disclosed are a microencapsulated drug prepared by the method for preparing biodegradable, biocompatible microparticles, and a pharmaceutical composition that includes biodegradable and biocompatible microparticles in a pharmaceutically acceptable carrier.

Issued: June 29, 1999
Inventor(s): Rickey; Michael E. & Ramstack; J. Michael & Lewis; Danny H.
Assignee(s): Alkermes Controlled Therapeutics Inc. II
A method for preparing biodegradable, biocompatible microparticles. A first phase is prepared that includes a biodegradable, biocompatible polymer, an active agent, and a solvent. An immiscible second phase is prepared. The first and second phases are combined to form an emulsion in which the first phase is discontinuous and the second phase is continuous. The two phases are immersed in a quench liquid that includes a quench medium and a quantity of the solvent. The quantity of the solvent is selected to control a rate of extraction of the solvent from the first phase. The first phase is isolated in the form of microparticles. Also disclosed is a microencapsulated active agent prepared by the method for preparing biodegradable, biocompatible microparticles.

Preparation of microparticles having a selected release profile
Patent 6,194,006
Issued: February 27, 2001
Inventor(s): Lyons; Shawn L. & Ramstack; J. Michael & Wright; Steven G.
Assignee(s): Alkermes Controlled Therapeutics Inc. II
An improved method for preparing microparticles that exhibit controlled release of an effective amount of an active agent over an extended period of time. More particularly, a method is provided for preparing microparticles having a selected release profile for release of active agent contained in the microparticles. By adjusting the degree of drying that is performed during the preparation of the microparticles, the release profile can be controlled. By performing no intermediate drying, an initial burst and a substantially linear release profile is achieved. By performing substantially complete intermediate drying, an initial lag phase and a substantially sigmoidal release profile is achieved.

Inventor(s): Lyons; Shawn L. & Wright; Steven G.
Assignee(s): Alkermes Controlled Therapeutics II Inc.
Apparatus and method for preparing microparticles. An emulsion is formed by combining two phases in a static mixing assembly. The static mixing assembly preferably includes a preblending static mixer and a manifold. The emulsion flows out of the static mixing assembly into a quench liquid whereby droplets of the emulsion form microparticles. The residence time of the emulsion in the static mixing assembly is controlled to obtain a predetermined particle size distribution of the resulting microparticles.
