SAN DIEGO & LAINATE, Italy--(BUSINESS WIRE)--Santarus, Inc. (NASDAQ:SNTS - News) and Cosmo Pharmaceuticals S.p.A. (SIX:COPN) today announced positive top-line results from the Phase III clinical study conducted in the U.S. and India to evaluate the safety and efficacy of budesonide MMX® for the induction of remission of mild or moderate active ulcerative colitis. The study results show that budesonide MMX 9 mg taken once daily met the primary endpoint of superiority to placebo (p=0.0143) in achieving clinical remission as measured by the ulcerative colitis disease activity index (UCDAI) score after eight weeks of treatment. Santarus and Cosmo Technologies Ltd., a subsidiary of Cosmo Pharmaceuticals, are collaborating on the budesonide MMX Phase III clinical program.
“These positive results are a major step toward the submission of a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for budesonide MMX 9 mg for the induction of remission of mild or moderate active ulcerative colitis,” said Gerald T. Proehl, president and chief executive officer of Santarus. “Assuming positive results in the European clinical study we plan to submit the NDA in the second half of 2011 following the completion of an ongoing double-blind, placebo-controlled extended use study.”
Mauro Ajani, chief executive officer of Cosmo Pharmaceuticals, said, “We are very pleased to announce positive results for the U.S. study with the 9 mg dose, which further validate the ability of our MMX technology to deliver an active pharmaceutical ingredient directly and efficiently to the colon. We are expecting to have the top-line results from the European Phase III study available in November.”
Under the statistical analysis plan submitted to the FDA for each Phase III study, to achieve statistical significance the budesonide MMX 9 mg and 6 mg treatment arms required a separate analysis at a p-value of 0.025 compared with the placebo group. The intent-to-treat (ITT) population in the pre-defined statistical analysis plan was all randomized patients who received at least one dose of a study drug, excluding patients with normal histology at baseline as determined by biopsy, or due to Good Clinical Practice (GCP) violations or major entry criteria violations.
The top-line study results indicate that budesonide MMX 9 mg and 6 mg were generally well tolerated and the frequency of treatment emergent adverse events was similar to placebo.
Budesonide MMX Phase III Study Design
Budesonide MMX is being evaluated for the treatment of mild or moderate active ulcerative colitis in two Phase III clinical studies, both of which are intended to support U.S. regulatory submission. The primary endpoint is the achievement of clinical remission as measured by a UCDAI score = 1 after eight weeks of treatment with a score of 0 for rectal bleeding and stool frequency, and = 1 point reduction from baseline in the endoscopy score without any sign of mucosal friability (an indicator of mucosal inflammation).
Each clinical study was a multicenter, randomized, double-blind, double-dummy, placebo-controlled four-arm study.
* Study CB-01-02/01 was conducted in the U.S. and India. In this study budesonide MMX 9 mg or 6 mg dosed once daily were compared to placebo. A reference arm using two Asacol 400 mg delayed-release tablets dosed three times a day for a total of 2400 mg daily (the FDA-approved dosage of Asacol for induction of remission of ulcerative colitis) was also included.
* Study CB-01-02/02 was conducted in Europe and compared budesonide MMX 9 mg or 6 mg dosed once daily to placebo. A reference arm using three Entocort EC® (budesonide) 3 mg capsules for a total of 9 mg dosed once daily was also included.
The Phase III clinical studies were powered to show a statistical difference between the two budesonide MMX treatment arms and placebo. The reference arms using Asacol in the U.S. study and Entocort EC in the European study were not powered to show statistical differences versus budesonide MMX.
Extended Use Study Ongoing Through Mid-2011
As previously reported, the FDA requested that the results from an additional 12-month extended use study be included in the Phase III clinical program to support a U.S. regulatory submission. This study is designed to:
* Evaluate the long-term safety and tolerability of budesonide MMX 6 mg, and
* Collect data on the efficacy of budesonide MMX 6 mg in the maintenance of remission of ulcerative colitis compared to placebo.
A total of 123 patients from the Phase III clinical studies in the U.S., India and Europe are enrolled in this double-blind, placebo-controlled extended use study, which is scheduled to be completed in mid-2011.
About Budesonide MMX
Budesonide MMX is an investigational drug that is a locally acting corticosteroid in a novel, patented, oral tablet formulation, which utilizes Cosmo’s proprietary MMX® multi-matrix system technology and is designed to result in the controlled release and distribution of budesonide throughout the length of the colon. Budesonide has topical anti-inflammatory activity and due to an extended first pass effect, has less systemic absorption than other corticosteroids.
About Ulcerative Colitis
Ulcerative colitis is a form of inflammatory bowel disease (IBD) that produces inflammation and ulcers along the inside of the colon. The inflammation can interfere with the normal function of the colon, often causing cramping, bloating, diarrhea, bleeding, fatigue, weight loss and frequent bowel movements, which may also strongly affect quality of life. It is believed that as many as 1.2 million people in the U.S. have IBD.
Ulcerative colitis is a chronic relapsing-remitting illness for which there is no known cure, but with appropriate treatment patients can manage their symptoms. However, it is estimated that up to 30% of patients with mild or moderate ulcerative colitis require add-on therapy to aminosalicylate (5-ASA) drugs. Patients refractive to treatment with 5-ASA drugs typically receive a course of an oral, systemically absorbed corticosteroid, the success of which may be limited by significant side effects. For moderate to severe cases of ulcerative colitis, immunosuppressant drugs or biologic drugs may be prescribed. If the condition does not respond to pharmaceutical therapy and the symptoms are severe, the patient may be referred for surgery.
