E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess the effect of a single daily dose of SB-656933-AAA on leukocyte migration to the inflamed colon after 1 and 7 days dosing as measured by 99mTc-HMPAO-labeled leukocyte scintigraphy in subjects with moderately active ulcerative colitis (UC) |
|
E.2.2 | Secondary objectives of the trial |
• To assess the safety and tolerability of 7-day repeat dose of SB-656933-AAA in subjects with UC. • To characterise the population pharmacokinetics of SB-656933 in subjects with UC. • To assess the PD effects of SB-656933-AAA after 1 and 7 days treatment with single daily dose in subjects with UC as measured by an ex-vivo whole blood PMN activation assay representing a functional consequence of CXCR2 receptor occupancy on neutrophils. • To assess the effect of SB-656933 on stool neutrophil markers using a faecal biomarker assay. • To characterise the PK/PD relationship between plasma exposure of SB-656933-AAA and 99mTc-HMPAO SPECT scintigraphic activity scores

A minimum list of drugs that will be screened for include amphetamines, barbiturates, cocaine, opiates, cannabinoids and benzodiazepines. 2. A positive pre-study Hepatitis B surface antigen or positive Hepatitis C antibody result within 3 months of screening. 3. A positive test for HIV antibody. 4.

History of sensitivity to any of the study medications, or components thereof or a history of drug or other allergy that, in the opinion of the investigator or GSK Medical Monitor, contraindicates their participation. 9.
