OTHER EVENTS. - --------------------- Entropin, Inc. ("Entropin") issued the following press release on June 27, 2001: NEWS RELEASE ------------ ENTROPIN ADDS FOURTH CLINICAL SITE FOR ESTEROM(R) PHASE II/III STUDY INVESTIGATOR TRAINING AT THREE EXISTING SITES COMPLETED INDIO, Calif. (June 27, 2001) - Entropin, Inc. (Nasdaq: ETOP, ETOPW), a specialty pharmaceutical company developing new therapeutics for painful soft tissue injuries and diseases, today announced the addition of a fourth clinical study site for its upcoming Phase II/III study with Esterom(R). Entropin also completed an Investigator Training Meeting in preparation for the study at the Company's first three clinical study sites. Investigators from these three sites, study site coordinators and representatives from key support vendors all attended a single comprehensive Investigator Training Meeting. The fourth clinical trial site, The Center for Rheumatology and Bone Disease Research of Wheaton, Maryland, is a division of Arthritis & Rheumatism Associates, a specialty medical group with more than 30,000 patient visits annually. The Company expects to complete the Investigator Training Meeting for this site within two weeks. "The addition of another premier clinical site and thoroughly educating the personnel at all four sites are integral to the success of our upcoming trial," said Thomas G. Tachovsky, Ph.D., Entropin's president and chief executive officer. "It is vital for all of the investigators to perform well-defined diagnostic tests uniformly prior to patient enrollment, to apply Esterom(R) solution properly to the shoulder area of enrolled patients, and to measure and record patient performance consistently throughout the study." Dr. Tachovsky continued, "At the conclusion of our comprehensive training session, the investigators enthusiastically demonstrated their commitment to the Phase II/III clinical trial of Esterom(R), and we are all looking forward to the initial patient enrollment." The Investigator Training Meetings featured a thorough review of the study protocol, the investigator manual and instructions on the proper application of Esterom(R). Attendees also participated in a hands-on workshop to familiarize themselves with the electronic case report form and the data collection system developed specifically for Entropin by Medidata Solutions, whereby patient data from each of the sites will be collected daily at a central website. This electronic data capture is designed to assist with patient enrollment and screening, to facilitate data monitoring throughout the study, to enhance data integrity and to shorten the time required for an analysis of the study results. The Company anticipates enrolling the first patient in the study during the third quarter of this year. Each of the four clinical study centers - The Cleveland Clinic Foundation, ProHealth Care 2 Associates, Tampa Medical Research Group and The Center for Rheumatology and Bone Disease Research - is a recognized center of excellence in orthopedics and in rheumatology. Enrollment of the 150 patients planned for the Phase II/III trial is expected to take six months. Entropin, Inc. is a pharmaceutical research and development company, initially focused on the development of Esterom(R), a novel topical therapeutic for the treatment of painful soft tissue injuries, such as tendonitis or back sprain, that result in impaired function.
