UCB Submits Marketing Authorisation Application in Europe for CIMZIA™, a New Crohn’s Disease Therapy


First European submission of a subcutaneously-administered anti-TNF for the treatment of Crohn’s disease.

BRUSSELS (Belgium), April 28, 2006 - UCB today announced the submission of a Marketing Authorisation Application (MAA) to the European Medicines Agency (EMEA) for the approval of CIMZIA™ (certolizumab pegol, CDP870) in the treatment of patients with Crohn’s disease. When approved, CIMZIA™ will represent the first and only biologic administered by monthly subcutaneous injection as a treatment for Crohn’s disease patients.

The European submission follows the filing of a Biologics License Application (BLA) for CIMZIA™ to the United States Food and Drug Administration (FDA) on March 1, 2006.

“As a leading European biopharmaceutical company, today’s submission to the EMEA is an important milestone for UCB, and underscores our commitment to providing a highly effective therapy for patients living with the burden of Crohn’s disease,” said Olav Hellebo, President of Inflammation Operations for UCB. “With the European MAA filing following closely behind our recent BLA filing to the FDA, the CIMZIA™ development programme is firmly on course. We also continue to explore other indications in the inflammation area for this promising biologic.”

The European submission is based on safety and efficacy data from over 1,500 patients with Crohn’s disease. The two pivotal phase III studies (PRECiSE 1 and PRECiSE 2) that support the MAA submission met their primary endpoints with statistical significance, demonstrating CIMZIA™’s sustained and consistent efficacy in patients with Crohn’s disease. The CIMZIA™ MAA submission represents the largest biologic clinical trial database submitted to the EMEA for Crohn’s disease treatment. The PRECiSE studies also represent the broadest clinical trial programme, in terms of patient type, in Crohn’s disease, encompassing patients with previous exposure to an anti-TNF treatment with a range of concomitant therapies and variable duration of disease.

“The results we have seen in the PRECiSE studies have been highly encouraging, suggesting CIMZIA™ to be well-tolerated and effective in the treatment and maintenance of response and remission in patients with Crohn’s disease,” commented Professor Stefan Schreiber, Professor of Medicine and Gastroenterology at the Christian-Albrechts University, Kiel, Germany, and a leading investigator in the CIMZIA™ clinical trials program. “In addition, CIMZIA™ when approved will offer the convenience of monthly dosing, combined with a patient-friendly subcutaneous route of administration.”

“With Crohn’s disease affecting almost half a million people in Europe, the unmet needs of these patients are significant,” said Prof. Paul Rutgeerts, Professor of Medicine at the Katholieke Universiteit Leuven, Belgium. “There is a definite need for new therapies, allowing physicians more options for providing effective long-term relief from the significant burden of this debilitating disease.”

In addition to the current development programme in Crohn’s disease, ongoing studies are investigating the efficacy and tolerability of CIMZIA™ in the treatment of rheumatoid arthritis and psoriasis.

CIMZIA™ is the first and only PEGylated Fab’ fragment of a humanized anti-TNF-alpha antibody (TNF - Tumour Necrosis Factor). The engineered Fab’ fragment retains the biologic potency of the original antibody. CIMZIA™ has a high affinity for human TNF-alpha, selectively neutralizing the pathophysiological effects of TNF-alpha. Over the past decade, TNF-alpha has emerged as a major target of basic research and clinical investigation. This cytokine plays a key role in mediating pathological inflammation, and excess TNF-alpha production has been directly implicated in a wide variety of diseases.

About the PRECiSE Program
Data from PRECiSE 2 demonstrated that within six weeks of initiating CIMZIA™, 64.1 percent of patients (428 of 668) achieved a clinical response as defined by greater than or equal to 100 point reduction in the Crohn’s Disease Activity Index (CDAI) score (a composite score of eight factors used to assess a patient’s wellness). Responders were randomized to CIMZIA™ 400 mg or placebo every four weeks. At the end of 26 weeks, significantly more patients, 62.8 percent (135 of 215) on CIMZIA™ vs. 36.2 percent (76 of 210) on placebo, maintained an overall clinical response. Additionally, at 26 weeks, significantly more of CIMZIA™ patients were in clinical remission (CDAI =150 points) compared to placebo patients, 47.9 percent (103 of 215) vs. 28.6 percent (60 of 210), respectively. CIMZIA™ was generally well tolerated with an adverse event profile similar to other anti-TNF agents. The PRECiSE clinical program is composed of four studies (PRECiSE 1, 2, 3, and 4). PRECiSE 3 and 4 are both 24-month open-label trials assessing the longer-term safety and tolerability of CIMZIA™ and are currently ongoing.

NOTE TO EDITOR: PRECiSE 2 data were presented at both the 2005 United European Gastroenterology Week and American College of Gastroenterology medical meetings 1. PRECiSE 1 data will be presented at Digestive Disease Week (20-25 May 2006, Los Angeles, CA).

About Crohn’s Disease
Crohn’s disease is a chronic and debilitating inflammatory disease of the gastrointestinal tract, most commonly affecting the end of the small intestine (the ileum) and beginning of the large intestine (the colon). Together with ulcerative colitis, Crohn’s disease belongs to the group of illnesses known as inflammatory bowel disease. Crohn’s disease affects nearly one million people worldwide and an estimated 500,000 people in Europe. People with Crohn’s disease may suffer an ongoing cycle of “flare-up” and remission. Symptoms of the disease include persistent diarrhoea, abdominal pain, and loss of appetite/weight, fever or rectal bleeding.2
