(Nasdaq: ETOP, ETOPW), a specialty pharmaceutical company developing new topical therapeutics for painful soft tissue injuries and diseases, today updated enrollment progress for its Phase II/III Clinical Trial of Esterom(R). Entropin's President and Chief Executive Officer, Thomas G. Tachovsky, Ph.D., commented, "Our Phase II/III study with Esterom(R) in treating impaired range of motion associated with acute painful shoulder is well underway. A total of 57 patients are currently enrolled in our 150 patient Phase II/III Study. Additional patients are being screened and we continue to receive inquiries daily from individuals interested in participating." "We are pleased with the current pace of patient enrollment and continue to be enthusiastic about the potential positive outcome of this study. We expect to complete patient enrollment and report the results of this study in the third quarter of 2002. While we continue to anticipate the need for at least one additional clinical study, we remain on track to file a New Drug Application (NDA) for Esterom(R) in 2004," added Dr. Tachovsky. This study is examining patients between the ages of 18 and 65 years who have a soft tissue affliction resulting in impaired function of the shoulder. The prior Phase II study, demonstrated that Esterom(R) provided statistically significant improvement for soft tissue afflictions for both the shoulders and the lower back. It is management's opinion that Esterom(R) has the potential to replace other current therapeutics for treating impaired physical function resulting from soft tissue injuries and diseases - such as tendonitis, impingement syndrome, bursitis and lower back sprain, and possibly, forms of arthritis. Esterom(R) is Entropin's investigational drug for patients suffering from these painful and limiting range of motion medical conditions. About Entropin - -------------- 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.
