Trial Outcomes & Findings for Oral OKT3 for the Treatment of Active Ulcerative Colitis (NCT NCT01287195)
NCT ID: NCT01287195
Last Updated: 2019-02-11
Results Overview
An adverse event is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events.

PRIMARY outcome
Timeframe: Baseline, Week 5Population: All participants enrolled in the study for whom data were available at both time points.
Peripheral blood mononuclear cells were (PBMCs) were isolated from blood samples taken from each participant at baseline and Week 5. PBMCs were stained with a panel of fluorochrome-conjugated antibodies against multiple surface and intracellular biomarkers, including Cluster of Differentiation (CD) 3, CD4, CD8, Forkhead box P3 protein (FOXP3) and latency-associated peptide (LAP). The percentage of T cells positive for each of these biomarkers was determined by fluorescence activated cell sorting (FACS) and the mean percentage of positive T cells for each biomarker for all analyzed participants is reported.

Timeframe: Baseline, Weeks 1, 3 and 5Population: All participants enrolled in the study for whom data were available at each time point.
PBMCs isolated from whole blood obtained from participants at baseline, Weeks 1, 3, and 5 were assessed for proliferation in cell culture using a radioactive thymidine incorporation assay. A higher number indicates a higher level of proliferation.

SECONDARY outcome
Timeframe: Baseline, Week 5Population: All participants enrolled in the study for whom data were available at each time point.
The Mayo Score is determined by the investigator by assigning a score to the following four assessments: stool frequency, rectal bleeding, physician's global assessment and endoscopy. Total range for Mayo score is 0-12 with a higher score indicating a worse outcome.

SCCAI is a symptom based questionnaire addressing five assessments, including bowel frequency day, bowel frequency night, urgency of defecation, blood in stool and general well-being. Score ranges from 0-15 with one additional point added for each manifestation of extracolonic features. A higher score indicates a worse outcome.
