SUPPLEMENTARY INFORMATION:

I. Background

    FDA is announcing the availability of a draft guidance for industry 
entitled ``Ulcerative Colitis: Clinical Trial Endpoints.'' The purpose 
of this draft guidance is to assist sponsors in the clinical 
development of drugs for the treatment of UC in adult and pediatric 
patients. Specifically, this draft guidance addresses FDA's current 
thinking regarding efficacy endpoints for UC clinical trials.
    UC is a chronic, relapsing disease characterized by diffuse mucosal 
inflammation of the colon. UC involves the rectum and it may extend 
proximally in a contiguous pattern to affect part of the colon or the 
entire colon. Clinical manifestations of active disease include bloody 
diarrhea (with or without mucus), urgency, tenesmus, abdominal pain, 
weight loss, fever, and malaise. In patients with extensive or severe 
inflammation, acute complications such as severe bleeding and toxic 
megacolon may occur. There is an increased risk of colorectal cancer in 
UC patients compared to the general population; risk factors include 
long duration of disease, extensive colonic involvement, severe 
inflammation and epithelial dysplasia, and childhood-onset disease. The 
signs and symptoms of UC in adults and children are similar; however, 
abdominal pain, disease involving the entire colon, extra-intestinal 
manifestations, proctitis (among girls), and disease severity 
necessitating colectomy are more common in children.
    This draft guidance is being issued consistent with FDA's good 
guidance practices regulation (21 CFR 10.115). The draft guidance, when 
finalized, will represent the current thinking of FDA on clinical trial 
endpoints for UC. It does not establish any rights for any person and 
is not binding on FDA or the public. You can use an alternative 
approach if it satisfies the requirements of the applicable statutes 
and regulations.

II. The Paperwork Reduction Act of 1995

    This draft guidance refers to previously approved collections of 
information that are subject to review by the Office of Management and 
Budget (OMB) under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-
3520). The collections of information in 21 CFR parts 312 and 314 have 
been approved under OMB control numbers 0910-0014 and 0910-0001, 
respectively.

IV. Electronic Access

    Persons with access to the Internet may obtain the draft guidance 
at either http://www.fda.gov/Drugs/GuidanceComplianceRegulatoryInformation/Guidances/default.htm or http://www.regulations.gov.
