Poster Titled 'Maintenance of Efficacy Without Compromising Safety When Switching From Oral Risperidone to Risperdal Consta', Posted On Alkermes' Website CAMBRIDGE, Mass.--(BW HealthWire)--Feb. 26, 2002--Alkermes, Inc., (NASDAQ: ALKS - news) today announced that it added a poster to its website entitled ``Maintenance of Efficacy Without Compromising Safety When Switching from Oral Risperidone to Risperdal Consta(TM), a Long-acting Injection Formulation of Risperidone.'' The poster was presented today, Tuesday, February 26, 2002 at 12:30pm ET at the Winter Workshop on Schizophrenia in Davos, Switzerland. This poster demonstrates the maintenance of efficacy without compromising safety when switching from Risperdal® (risperidone) tablets to Risperdal Consta. The poster is available on the Alkermes website at www.alkermes.com/news. A new drug application (NDA) for Risperdal Consta was submitted to the U.S. Food and Drug Administration on August 31, 2001 by Johnson & Johnson Pharmaceutical Research & Development, which conducted the clinical-development program. If approved by the FDA, Risperdal Consta will be marketed in the United States by Janssen Pharmaceutica Products, LP and manufactured by Alkermes. Risperdal is currently the most widely prescribed antipsychotic medication in the United States and would be the first ``atypical'' antipsychotic to be available in a long-acting formulation. Risperdal Consta is a long-acting injectable formulation of Risperdal that uses Alkermes' proprietary, injectable sustained-release drug delivery technology, Medisorb®. The technology is based on the encapsulation of drugs into small polymeric microspheres that degrade slowly and release the medication at a controlled rate following subcutaneous or intramuscular injection. Alkermes is developing Medisorb product candidates in collaboration with pharmaceutical and biotechnology companies and on its own. <snip>
