Phase 2 Study Shows Clinical Response, Remission Continues After Treatment With Sargramostim/GM-CSF
"These promising data demonstrate that Leukine may provide a unique approach to the treatment of Crohn's disease," said Dr. Joachim-Friedrich Kapp, Specialized Therapeutics, a member of the Schering AG, Germany Group. "Leukine, due to its innovative mode of action, may offer the advantage of avoiding negative and serious side effects that are often seen with immunosuppressants or steroids."
About the trials
Follow-up of Phase II Study Data
This multi-center, randomized, double-blind, placebo-controlled Phase II study evaluated 124 patients randomized 2:1 to Leukine or placebo administered daily for eight weeks. Evaluation occurred at the end of treatment and 30 days after discontinuation of treatment. Patients with response at the end of treatment were followed for up to six months.
The follow-up data show that clinical response and remission, as well as improved quality-of-life, were maintained after drug therapy was discontinued, compared with placebo. Specifically, nearly half of patients maintained clinical response and remission for a median of 8 - 10 weeks, and in approximately 15 percent of patients, response to therapy was maintained for at least six months. In addition, there was no exacerbation of the disease when therapy ended. Leukine was generally well-tolerated and not associated with serious adverse events.
About Crohn's Disease
Crohn's disease is a chronic and serious inflammatory disease of the gastrointestinal (GI) tract. Crohn's disease affects men and women equally and seems to be more common within families. About 20 percent of people with Crohn's disease have a blood relative, most often a brother or sister, with some form of inflammatory bowel disease (IBD).
Crohn's disease can be difficult to diagnose because its symptoms are similar to other intestinal disorders such as irritable bowel syndrome (IBS) and ulcerative colitis. Crohn's disease causes inflammation in the small intestine and usually occurs as an inflammation of the lower part of the small bowel (ileum); however, it can affect any part of the digestive tract from the mouth to the anus. The inflammation from Crohn's disease can extend deeply into the lining of the affected organ, causing pain and frequent bowel movements.
Currently, there is no cure for Crohn's disease, and many patients rely on steroids and/or immunosuppressive therapies that do not consistently prevent recurrence of the disease.
Leukine is a hematopoietic growth factor that stimulates neutrophils, monocytes/macrophages, and dendritic cells. Leukine was approved in the U.S. in 1991, where it is marketed by Berlex, Inc., the U.S. affiliate of Schering AG, Germany.
Leukine is the only colony-stimulating factor approved in the U.S. for use following induction chemotherapy in older adults with acute myelogenous leukemia (AML). The aim of the treatment is to shorten the time to neutrophil recovery and reduce the incidence of severe and life-threatening infections. Leukine has also been approved in the U.S. for use in four additional indications: myeloid reconstitution following allogeneic and autologous bone marrow transplantation (BMT), peripheral blood stem cell (PBSC) mobilization and subsequent myeloid reconstitution in patients undergoing PBSC transplantation, and bone marrow transplantation failure or engraftment delay.
