BioSphere Medical Announces New Journal Articles Published Discussing Uterine Fibroid Embolization

BioSphere Medical, Inc. (NASDAQ: BSMD) ("BioSphere” or the "Company”) – a medical device company that has pioneered the use of bioengineered microspheres to treat uterine fibroids, hypervascularized tumors and vascular malformations by a minimally invasive, image-guided medical procedure called embolotherapy – today reported two journal articles on uterine fibroid embolization (UFE): the New England Journal of Medicine has published a feature article concluding that UFE should be discussed as a choice for an appropriate patient who wishes to avoid hysterectomy for the treatment of fibroids; the American Journal of Obstetrics & Gynecology has published a review concluding that UFE is an option that all physicians may wish to discuss with all patients who are being offered surgical solutions.

The NEJM article, authored by Scott C. Goodwin, M.D. of the Department of Radiological Sciences, University of California at Irvine, Orange and James B. Spies, M.D. M.P.H, of the Department of Radiology, Georgetown University Medical Center, Washington, D.C. was published on August 13, 2009 (http://www.sirweb.org/news/newsPDF/Release_UFE_NEJM_final.pdf). The authors present a case vignette with a recommendation for treatment with UFE following a review of clinical options and adverse events for both the procedure and hysterectomy. They also note in the article that the American College of Obstetricians and Gynecologists has issued guidelines based on good and consistent Level A evidence that "uterine artery embolization is a safe and effective option for appropriately selected women who wish to retain their uteri.”

The AJOG article was authored by Linda D. Bradley, M.D. of the Department of Obstetrics and Gynecology, Cleveland Clinic, Cleveland, Ohio, with partial funding from BioSphere Medical, and was published in the August 2009 issue. In the article, Dr. Bradley reviews the clinical research, discusses benefits and drawbacks and presents recommendations for patient triage prior to UFE. She also notes that "a collaborative and multidisciplinary practice between gynecologists and interventional radiologists represents state-of-the-art care for women with fibroids. With such an approach, our patients can be given a truly informed consent.”

Richard Faleschini, BioSphere’s president and chief executive officer, said, "The New England Journal of Medicine is a very prestigious journal, and its influence is far reaching. We are very pleased that uterine fibroid embolization has been highlighted in the Clinical Therapeutics feature of the Journal as a key treatment option for women with symptomatic fibroids who have been evaluated appropriately. In addition, the review article in the American Journal of Obstetrics & Gynecology is an excellent primer about UFE for gynecologists and primary care physicians, and advocates the best practice of cross-specialty consultation and collaboration to provide women with fibroids the best care. We believe that women with fibroids should be provided with meaningful comparative information on all treatment options so that they may make an informed decision and choice. And, we are confident that if nonsurgical UFE is the suitable choice, that all constituencies win because, when compared to the surgical alternatives, UFE provides safe and effective clinical outcomes, low relative complications, a quick return to the activities of daily living, and favorable economics for patients, providers, and payers. This is a great combination, particularly in the current economic and healthcare environment. Thus, we expect that as these two journal articles are disseminated to and absorbed by women’s physicians, the adoption of UFE will continue to expand.”
