The committee's view was based, in part, on the fact that the majority of study patients were treated in a single specialty treatment center. "Serono is disappointed with the recommendation of the Advisory Committee," said Dr. Joseph Gertner, Vice President and Head of Metabolic Endocrinology Clinical Development, Serono, Inc. "There is a substantial clinical need to provide more effective treatments to patients with short bowel syndrome, a rare orphan condition. We will evaluate our next steps and will continue to work closely with the FDA to fully understand and address the outstanding issues." The Advisory Committee recommendation is considered by the FDA in making its decision. This committee recommendation does not impact the current use of Serostim(R) in the approved indication of AIDS wasting. SBS is a rare, serious and potentially life-threatening condition that follows extensive surgical removal of the small intestine as a treatment for acute or chronic disorders of the intestine. Removal of a large portion of the bowel results in impaired absorption of nutrients. Currently the standard treatment for SBS involves careful management of dietary intake, or where appropriate, a process referred to as parenteral nutrition in which patients are fed through an intravenous tube. Surgical transplant of the intestine may also be performed for this condition. There are an estimated 10,000-20,000 patients in the United States who are receiving long-term intravenous parenteral nutrition for SBS. At the committee meeting, Serono presented data from a pivotal study to evaluate the change in total parenteral nutrition requirements in adult patients with SBS who are dependent on parenteral nutrition. In the double-blind, controlled, parallel group Phase III study, 41 patients were randomly assigned to one of three study arms: a specialized diet supplemented with oral glutamine alone; Serostim(R) with a specialized diet alone; or Serostim(R) with a specialized diet with glutamine. The results of the study were positive with total parenteral nutrition volume, total parenteral nutrition calories, and frequency of infusion decreasing significantly more in the Serostim(R) plus specialized diet group as compared to the glutamine supplemented specialized diet group (p values 0.043, 0.005, and 0.025 respectively). The corresponding reductions in the Serostim(R) plus glutamine supplemented diet group as compared to the glutamine supplemented specialized diet group were larger and all were highly significant (p values less than 0.001). Serostim(R) was granted an orphan drug designation for use alone or in combination with glutamine in the treatment of patients with short bowel syndrome by the FDA Office of Orphan Products Development. Serostim(R) is currently approved by the FDA for the treatment of AIDS wasting or cachexia. ABOUT SEROSTIM(R) Serostim(R) [somatropin (rDNAorigin) for injection] is the only growth hormone approved by the US Food and Drug Administration for the treatment of AIDS wasting or cachexia. Serostim(R) received FDA accelerated approval in 1996 based upon the analysis of changes in body weight and lean body mass in surrogate endpoints in clinical studies up to 12 weeks in duration. Serostim(R) is now on the market in 12 countries. Serostim(R), when taken as currently prescribed in 6mg doses over 12 weeks, is generally well tolerated. The most common adverse reactions to Serostim(R) are increased tissue turgor (generally swelling of hands and feet) and musculoskeletal discomfort (pain, swelling or stiffness). Generally mild to moderate in severity, these symptoms usually resolve spontaneously with continued treatment or are effectively managed with analgesic therapy or after reducing the weekly dose. Elevations in mean blood glucose levels can also occur. Patients with other risk factors for glucose intolerance should be monitored closely. When used in patients with HIV disease, Serostim(R) must be used in conjunction with antiretroviral therapy. Full prescribing information for Serostim(R) is available at www.aidswasting.com. ------------------- ABOUT SERONO Serono, Inc., located in Rockland, MA, is the US affiliate of Serono, a global biotechnology leader.
