Novavax, Inc. Head Of Pharmaceutical Development To Present On Micellar Nanoparticle Technology At Particles 2006 Meeting

MALVERN, Pa., May 10 /PRNewswire-FirstCall/ -- Novavax, Inc. today announced that Robert Lee, Ph.D., Vice President - Pharmaceutical Development, is scheduled to present at the Particles 2006 Conference on Tuesday, May 16, 2006 at 3:30 p.m. EDT at the Wyndham Orlando Resort in Orlando, Florida. Dr. Lee will describe the latest developments regarding Novavax’s proprietary Micellar Nanoparticle (MNP) drug delivery technology. MNPs are nanoemulsion formulations for topical or transdermal drug delivery that look and feel like cosmetic lotions. MNP technology creates functional depots of drug in skin that can reduce the required number of doses and/or the amount of each dose when compared with current topical formulations. Because it can incorporate a much broader spectrum of active pharmaceutical ingredients, MNP technology allows the formulation of drugs that previously would not be conducive to transdermal delivery. “I am pleased to be a presenter at this conference and would like to thank Dr. John Texter, General Chair of the conference, for his invitation to participate in this meeting,” said Dr. Lee.

According to the Particles 2006 web site (http://nanoparticles.org/Particles2006/), “Particles 2006 is an international conference examining the science, technology, and business aspects of medical/biochemical diagnostic, pharmaceutical, and drug delivery applications of particle technology. Symposia will address diverse topics including nanoparticles, hydrogels, chemical and drug delivery, controlled release, suspensions, inhalation, liposomes, micelles & microemulsions, characterization, gene delivery, chemical and biochemical diagnostics, separations, surface modification, critical and supercritical fluid applications, spray drying, emulsions, and multiple emulsions. The conference targets practicing scientists, clinical research physicians, engineers, managers, innovators, and entrepreneurs, and embraces the theme ‘particles for detection and treatment.’”

More About Novavax’s Micellar Nanoparticles

MNPs represent a composite vehicle that presents the active pharmaceutical ingredient in a variety of fractions: aqueous or hydro-alcoholic solution, micellar solubilized form, oil fraction and as surface-stabilized micro-/nano- crystals. This formulation approach creates a microreservoir-dissolution- controlled system that is capable of incorporating both water-soluble and water-insoluble active pharmaceutical ingredients and delivering them either topically (skin being the target tissue) or transdermally (systemic delivery). Additionally, MNP technology is being evaluated for other routes of administration.
