Patent number: 5874006Abstract: A process for the aseptic concentration of collagen from about 0.25% (w/w) suspensions to gels of 15% using vortex flow filtration with a variety of membrane types--ultrafiltration and microfiltration and polymeric and stainless steel is provided. The resulting gels are suitable for use in medical products and/or pharmaceutical formulations. This process achieves high degree of concentration in a closed system and at high flux with minimal trans-membrane pressure drop.Type: GrantFiled: October 31, 1996Date of Patent: February 23, 1999Assignee: Matrix Pharmaceutical, Inc.Inventors: Richard Lee, Daniel Prows, Louis Fries

Patent number: 5874402Abstract: Methods are provided for the treatment of a host suffering from a cellular proliferative disease through administration of a chemotherapeutic agent in conjunction with a cell membrane permeant. Optionally, the cell membrane permeant and/or chemotherapeutic agent will be present in a pharmaceutically acceptable vehicle capable of acting as a depot. In the subject methods, the chemotherapeutic agent and membrane permeant are administered at least proximal to a target site of the host. Administration of chemotherapeutic agents in accordance with the subject methods results in improved efficacy of, and/or decreased host toxicity to, the intralesionally administered chemotherapeutic agent.Type: GrantFiled: May 16, 1997Date of Patent: February 23, 1999Assignee: Matrix Pharmaceutical, Inc.Inventors: Saira Singh, Richard E. Jones, Dennis M. Brown
