Design outcomes

Primary

MeasureTime frame
Compare antibody titers of VZV-specific IgG antibodies at baseline and at weeks 12 between within group.

Secondary

MeasureTime frame
a)Secondary immunogenicity outcome - Compare antibody titers of VZV-specific IgG antibodies at baseline and at weeks 12 between for each group. - Compare antibody titers of VZV-specific IgG antibodies at baseline and at weeks 4 and 8 between and for each group. - Measure antibody titers of VZV-specific IgG antibodies at baseline and at weeks 4, 8, and 12 in both groups. - Calculate of absolute geometric mean titers (GMT) of antibody titers of VZV-specific IgG antibodies in both groups. - Calculate the percentage of patients with a fold change of at least 1.5 times from baseline in antibody titers of VZV-specific IgG antibodies in both groups at weeks 4, 8, and 12. - Compare antibody titers of VZV-specific IgG antibodies between the two groups at weeks 4 and 8. - Compare antibody titers of VZV-specific IgG antibodies between the two groups and each group between weeks 4 and 8 and 12 and between weeks 8 and 12. b) Secondary clinical outcome - Composite index of disease activity (including CDAI, SDAI, DAS28-CRP scores and HAQ-DI). - HZ events until end of study (week 12) in patients treated with tofacitinib. - The presence of a disease flare in RA until the end of the study. - Adverse events and serious adverse events until the end of the study.
