An Open Label, 7-day Repeat Dose Study to Evaluate the Pharmacodynamics of SB-656933-AAA in Patients With Ulcerative Colitis.

Change From Baseline at 1 and 7 Days Treatment With Daily Dose of SB-656933-AAA in 99m(Technetium-hexamethyl Derivative of Propylene Amine Oxide)Tc-HMPAO Leukocyte Single Photon Emission Computerized Tomography (SPECT) Scintigraphic Activity Scores (SAS)

时间窗: Baseline (Day -1) and Day 1 and 7

Data has been presented for participants since change from Baseline data was not analyzed. For scintigraphy, blood was obtained for radiolabelling. Labelled white cells were then injected for SPECT scintigraphy and scanning began 45 minutes after injection of labelled White blood cells (WBCs). SPECT images of the colon were divided into 5 segments: ascending colon, transverse colon, descending colon, sigmoid, and rectum.T he SPECT segment uptake ratio was expressed as a fraction of bone marrow activity obtained from counts in the lumbar spine. The SPECT segment uptake ratio was converted into a four-point (0 to 3) segmental SPECT severity score where grade 0 was equal to no uptake. Only 3 participants were included before the study was discontinued.It was not possible to draw any meaningful conclusions from the very limited data available. Data has been presented for the 3 participants (99001, 99002 and 99003) since the analysis was not done. Baseline was Day -1.
