CHICAGO, May 9, 2011 /PRNewswire/ -- New study findings showed that treatment with STELARA® (ustekinumab) induced and
Crohn's disease, a chronic autoimmune disorder of the gastrointestinal tract, affects an estimated 700,000 Americans, and up to three quarters of people living with Crohn's disease may require surgery when medications can no longer control the symptoms of the disease.(1)
"Nearly half the patients participating in the study had a previous inadequate response to at least two TNF antagonists," said William Sandborn, M.D., University of California at San Diego, and lead study investigator. "While TNF blockers have advanced the treatment of Crohn's disease, for patients who do not respond or lose response, treatment options are limited. These results suggest the potential of STELARA as a treatment option for Crohn's disease, which is promising considering many patients still struggle with the debilitating effects of this immunological disease as a result of lack of response or loss of response to previous biologic treatment."
In the study, patients received one of three intravenous (IV) doses of STELARA or placebo at week 0. At week 6, 36.6 percent, 34.1 percent and 39.7 percent of patients receiving STELARA 1 mg/kg, 3 mg/kg or 6 mg/kg, respectively, achieved clinical response, compared with 23.5 percent of patients receiving placebo (P = 0.021 for STELARA 1 mg/kg vs. placebo; P = 0.057 for STELARA 3 mg/kg vs. placebo; P = 0.005 for STELARA 6 mg/kg vs. placebo). The difference in clinical remission was not statistically significant at week 6, a secondary endpoint, with any of the doses tested compared with placebo. In the maintenance phase of the study, individuals classified as responders to STELARA at week 6 were re-randomized to receive subcutaneous (SC) STELARA 90 mg or placebo at weeks 8 and 16. At week 22, 69.4 percent of patients maintained clinical response with continued STELARA treatment compared with 42.5 percent of patients receiving placebo (P < 0.001). Clinical remission was seen in 41.7 percent of initial STELARA responders who continued with therapy compared with 27.4 percent of responders re-randomized to receive placebo (P = 0.029).
"Based on these positive results, we look forward to studying STELARA in a Phase 3 program for the treatment of moderate to severe Crohn's disease, both in patients who have failed conventional treatment and in those who have failed anti-TNF therapy," said Jerome A. Boscia, M.D., Head of Immunology Development, Centocor Research & Development, Inc. "We believe STELARA holds great promise as a 'pipeline in a product' for the treatment of multiple inflammatory conditions, including Crohn's disease, and we look forward to the continued clinical development of this biologic therapy."
About the CERTIFI Trial
The Phase 2b, Multicenter, Randomized, Double-blind, Placebo-controlled, Parallel Group Study to Evaluate the Efficacy and Safety of Ustekinumab Therapy in Subjects With Moderately to Severely Active Crohn's Disease Previously Treated With TNF Antagonist Therapy (CERTIFI) trial included 526 patients with moderately to severely active Crohn's disease who were randomized to receive IV-administered STELARA 1 mg/kg, 3 mg/kg, 6mg/kg or placebo. All participating patients had previously failed or proved to be intolerant to a range of TNF antagonists including infliximab (REMICADE®), adalimumab (Humira®) or certolizumab pegol (Cimzia®). The primary endpoint was clinical response (at least a 100 point reduction from baseline CDAI scores) at week 6. At week 8, patients who were classified as responders or non-responders to IV STELARA at week 6 were re-randomized to receive SC STELARA 90 mg or placebo at weeks 8 and 16. Patients who responded to IV placebo by week 6 received SC placebo at weeks 8 and 16, while non-responders received SC STELARA 270 mg at week 8 followed by STELARA 90mg at week 16.
Rates of adverse events (AEs) and serious AEs were similar overall for STELARA and placebo groups, and both IV and SC STELARA were well-tolerated by study participants. There were similar proportions of overall AEs, serious AEs and infections in the STELARA- and placebo-treated groups during both the induction and maintenance phases. Through week 22, there were no deaths, serious opportunistic infections or cases of tuberculosis, malignancies or major adverse cardiovascular events. Infusion and injection site reactions were uncommon in patients receiving STELARA or placebo and none were serious.
About Crohn's Disease
Crohn's disease, a chronic inflammatory disease of the gastrointestinal tract, affects approximately 700,000 Americans. The cause of Crohn's disease is not known, but the disease is associated with abnormalities of the immune system that could be triggered by a genetic predisposition or diet and other environmental factors. Symptoms of Crohn's disease can vary but often include abdominal pain and tenderness, frequent diarrhea, rectal bleeding, weight loss and fever. There is currently no cure for Crohn's disease.
STELARA, a human interleukin (IL)-12 and IL-23 antagonist, is approved for the treatment of adult patients (18 years or older) with moderate to severe plaque psoriasis who are candidates for phototherapy or systemic therapy. IL-12 and IL-23 are naturally occurring proteins that are believed to play a role in psoriasis. For more information about STELARA, visit www.STELARAinfo.com.

Important Safety Information
STELARA® is a prescription medicine that affects your immune system. STELARA® can increase your chance of having serious side effects including:
STELARA® may lower your ability to fight infections and may increase your risk of infections. While taking STELARA®, some people have serious infections, which may require hospitalization, including tuberculosis (TB), and infections caused by bacteria, fungi, or viruses.
You should not start taking STELARA® if you have any kind of infection unless your doctor says it is okay.
Before starting STELARA®, tell your doctor if you think you have an infection or have symptoms of an infection such as:
After starting STELARA®, call your doctor right away if you have any symptoms of an infection (see above).
STELARA® can make you more likely to get infections or make an infection that you have worse. People who have a genetic problem where the body does not make any of the proteins interleukin 12 (IL-12) and interleukin 23 (IL-23) are at a higher risk for certain serious infections that can spread throughout the body and cause death. It is not known if people who take STELARA® will get any of these infections because of the effects of STELARA® on these proteins.
STELARA® may decrease the activity of your immune system and increase your risk for certain types of cancer. Tell your doctor if you have ever had any type of cancer.
Reversible posterior leukoencephalopathy syndrome (RPLS)
RPLS is a rare condition that affects the brain and can cause death. The cause of RPLS is not known. If RPLS is found early and treated, most people recover. Tell your doctor right away if you have any new or worsening medical problems including: headache, seizures, confusion, and vision problems.
