Outcome Measures
Primary Outcomes (5)
Number of Participants With Adverse Events
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.
From baseline to Week 10
Number of Participants With Anti-Drug Antibodies
Serum samples were obtained to measure anti-drug antibodies during the study.
From baseline to Week 10
Percentage of Biomarker-positive Immune Cells
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.
Baseline, Week 5
T Cell Proliferation of PBMCs in Cell Culture
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.
Baseline, Weeks 1, 3 and 5
Cytokine Production by PBMCs in Cell Culture
Cytokine production was assessed in cell cultures of PBMCs obtained from participants at baseline, Weeks 1, 3 and 5. The following cytokines were detected and are reported here: interferon gamma (IFN-gamma), interleukin (IL)-17A, IL-6, IL-1 beta, tumor necrosis factor (TNF) and IL-10.
Baseline, Weeks 1, 3 and 5
