New Data Show CIMZIA(TM) (certolizumab pegol) May Improve Productivity in Work and with Daily Activities for People with Crohn's Disease

Data also show improved quality of life and lower levels of disease severity with CIMZIA(TM) (certolizumab pegol)

ATLANTA, Oct. 23 (HSMN NewsFeed) -- UCB announced today that additional data from the PRECiSE 2 clinical trial program demonstrate that CIMZIA(TM) (certolizumab pegol), administered subcutaneously every four weeks with an additional induction dose at week 2, produces sustained significant improvements in work productivity and daily work activities in patients with moderate to severe Crohn's disease. Data to be presented at the 2006 American College of Gastroenterology (ACG) Annual Scientific Meeting in Las Vegas, Nevada, showed that patients receiving CIMZIA(TM) (certolizumab pegol) missed nearly 10% less work and had 15% less work impairment than people taking placebo.

Brian Feagan, M.D., Professor of Medicine and Epidemiology and Biostatistics at the University of Western Ontario, a PRECiSE 2 investigator and co-author on the study, commented on how these results may help to improve work-related and other daily activities for people with Crohn's disease. "Carrying on a normal life at home and at work is a big challenge for people with Crohn's disease. These promising results suggest that treatment with CIMZIA may allow Crohn's patients with moderate to severe symptoms to be more productive at work and carry out their daily work activities more easily. These are important results suggesting CIMZIA may help alleviate absenteeism and contribute to an increase in productivity."

"The comprehensive analyses from PRECiSE 2 continue to provide insights on the positive impact CIMZIA may have on patients' disease activity and overall quality of life. We continue to work toward bringing CIMZIA to market as soon as possible to satisfy unmet needs and help advance treatment of Crohn's disease for patients," said David Robinson, Vice President and General Manager, UCB.

About the Study

In the PRECiSE 2 study, patients responding at Week 6 to open-label induction therapy with CIMZIA(TM) (certolizumab pegol) were randomized to either placebo (n=210) or CIMZIA(TM) (certolizumab pegol) (n=215) and followed for a total of 26 weeks. In this trial, 62.8% of CIMZIA(TM) (certolizumab pegol) patients, compared to 36.2% of placebo patients, maintained clinical response at Week 26 (p<0.001). Clinical response was defined as a greater than or equal to 100 point decrease in CDAI. Similarly, 47.9% of CIMZIA(TM) (certolizumab pegol) patients were in clinical remission at week 26 compared to 28.6% on placebo (p<0.001). Remission was defined as CDAI less than or equal to 150 points.

The new analysis presented at ACG evaluated the impact of treatment on work-related outcomes assessed via the Work Productivity and Activity Impairment(i) (WPAI) questionnaire administered pre-study and at Week 26. In all four dimensions of the WPAI, CIMZIA(TM) (certolizumab pegol) produced significant improvements compared to placebo. Specifically, in addition to 9.9% less work missed and 15.4% less impairment while working (p= 0.03 and p< 0.001, respectively vs. placebo), CIMZIA(TM) (certolizumab pegol) was associated with 14.3% less overall work impairment (p= 0.004) and 9.1% less activity impairment (p= 0.004).

Additional PRECiSE 2 Data Presented at ACG Support These Results

Additional analyses from PRECiSE 2 presented at the 2006 ACG meeting provide insights into the observed improvements in work productivity and daily activities associated with CIMZIA(TM) (certolizumab pegol) treatment.
-- Measurements of health-related quality of life, as assessed by the
Inflammatory Bowel Disease Questionnaire (IBDQ)(ii) showed that
CIMZIA(TM) (certolizumab pegol) produced rapid, overall improvements
during treatment induction, and sustained those improvements during the
maintenance phase through Week 26 compared to placebo. Furthermore,
the proportion of patients considered responders (based on an IBDQ
score increase of at least 16 points), was significantly greater with
CIMZIA(TM) (certolizumab pegol) compared to placebo (p< 0.001).

-- Overall health status, as reported by patients using the Short-Form
Health Survey 36-Item (SF-36)(iii) and the EuroQoL-5 Dimensions (EQ-
5D)(iv) questionnaires, improved during induction to levels
approximating scores found in the general population. These
improvements were sustained to a significantly greater extent with
CIMZIA(TM) (certolizumab pegol) compared to placebo during the
maintenance phase. Specifically, the overall mental and physical
component summaries of the SF-36 were significantly higher compared to
placebo at Week 26 (p= 0.001, and p= 0.014 respectively). The Visual
Analog Score (VAS) of the EQ-5D was also maintained at a significantly
higher level with CIMZIA(TM) (certolizumab pegol) than with placebo (p=

-- Finally, significant correlations (p< 0.0001) were reported between the
improved WPAI scores and CDAI scores demonstrating less disease
severity, decreased abdominal pain, and general well being. Strong
correlations (p< 0.0001) also existed between WPAI scores and improved
quality of life as reflected by the IBDQ.


UCB filed a BLA with the Food and Drug Administration (FDA) for CIMZIA(TM) (certolizumab pegol) in the treatment of Crohn's disease on February 28th, 2006 and on April 28, 2006 submitted a Marketing Authorization Application (MAA) to the European Medicines Agency (EMEA) for the same indication. CIMZIA(TM) (certolizumab pegol) is the first and only PEGylated Fab' fragment of a humanized anti-TNF-alpha antibody (TNF-alpha; Tumour Necrosis Factor), evaluated as once-monthly dosing administered subcutaneously. The engineered Fab' fragment retains the biologic potency of the original antibody without the cytotoxicity mediated by the Fc portion present in the original monoclonal antibodies. CIMZIA(TM) (certolizumab pegol) 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 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 including an estimated 500,000 people in the United States. People with Crohn's disease may suffer an ongoing cycle of "flare-up" and remission. Symptoms of the disease include persistent diarrhea, abdominal pain, and loss of appetite/weight, fever or rectal bleeding. In an effort to provide Crohn's disease patients with disease management information and resources designed expressly with their needs in mind, UCB has launched, a dynamic, cutting-edge web site focused on helping patients thoroughly understand Crohn's disease and live with it every day.

(i)The Work Productivity and Activity Impairment (WPAI) was developed
to assess validity and accuracy of the Work Productivity and
Activity Impairment questionnaire in irritable bowel syndrome as a
tool for quantifying the effects of irritable bowel syndrome on
productivity and daily activities. Discriminative validity of the
Work Productivity and Activity Impairment questionnaire in irritable
bowel syndrome was established, making it the only validated tool
for measuring the relative differences between disease severity
groups and quantifying work productivity loss and activity
impairment in irritable bowel syndrome patients.

(ii) Inflammatory Bowel Disease Questionnaire (IBDQ) assesses quality of
life of patients with inflammatory bowel diseases.

(iii) A 36-item short-form (SF-36) was constructed to survey health status
in the Medical Outcomes Study. The SF-36 was designed for use in
clinical practice and research, health policy evaluations, and
general population surveys. The SF-36 includes one multi-item scale
that assesses eight health concepts
