A Study of the Effects of RoActemra/Actemra on Vaccination in Patients With Rheumatoid Arthritis on Background Methotrexate (VISARA)

Phase 4
Completed
Conditions
Rheumatoid Arthritis
Interventions
Biological: tocilizumab
Biological: 23-Valent Pneumococcal Polysaccharide Vaccine
Biological: Tetanus Toxoid Adsorbed Vaccine
Registration Number
NCT01163747

Genentech, Inc.
Brief Summary

This randomized, parallel-group, open-label study will evaluate the effect of Actemra (tocilizumab) on vaccination in patients with active rheumatoid arthritis who have an inadequate response to methotrexate and who have had an inadequate clinical response or were intolerant to treatment with one or more anti-tumor necrosis factor (anti-TNF) therapies.

Primary Outcome Measures
NameTimeMethod
Percentage of Participants Who Responded to ≥ 6 of 12 Anti-pneumococcal Antibody SerotypesBaseline (Week 3) and Week 8 (5 weeks post-vaccination)

Serum levels of antibody to pneumococcal vaccine were drawn 5 weeks after vaccination with 23-valent pneumococcal polysaccharide vaccine to assess humoral immune response. A positive response to the pneumococcal vaccine was defined as a 2-fold increase in serum antibody titers from Baseline or an increase of \> 1 mg/L from Baseline levels.

The 12 serotypes evaluated were pneumococcal serotypes 1, 3, 4, 6B, 8, 9N, 12F, 14, 19F, 23F, 7F, and 18C.

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants Who Responded to Combinations of 12 Anti-Pneumococcal Antibody SerotypesBaseline (Week 3) and Week 8 (5 weeks post-vaccination)

Serum levels of antibody to pneumococcal vaccine were drawn 5 weeks after vaccination with 23-valent pneumococcal polysaccharide vaccine to assess humoral immune response. A positive response to the pneumococcal vaccine was defined as a 2-fold increase in serum antibody titers from Baseline or an increase of \> 1 mg/L from Baseline levels.

The 12 serotypes evaluated were pneumococcal serotypes 1, 3, 4, 6B, 8, 9N, 12F, 14, 19F, 23F, 7F, and 18C.

Percentage of Participants With a Positive Response to Tetanus Toxoid VaccinationBaseline (Week 3) and Week 8 (5 weeks post-vaccination)

A positive response to the tetanus toxoid vaccination was defined as antibody levels ≥ 0.2 IU/mL for participants with Baseline tetanus antibody levels \< 0.1 IU/mL, or a 4-fold increase in antibody levels compared with Baseline for participants with Baseline tetanus antibody levels ≥ 0.1 IU/mL.

Change From Baseline in Levels of Anti-pneumococcal Antibody 5 Weeks After VaccinationBaseline (Week 3) and Week 8 (5 weeks post-vaccination)

Levels of anti-pneumococcal antibodies were measured by a central laboratory from serum samples taken prior to vaccination (Week 3) and 5 weeks post vaccination (Week 8).

Change From Baseline in Levels of Anti-tetanus Antibody 5 Weeks After VaccinationBaseline (Week 3) and Week 8 (5 weeks post-vaccination)

Levels of anti-tetanus antibodies were measured by a central laboratory from serum samples taken prior to vaccination (Week 3) and 5 weeks post vaccination (Week 8).

Percentage of Participants Who Responded to Each of the 12 Anti-Pneumococcal Antibody SerotypesBaseline (Week 3) and Week 8 (5 weeks post-vaccination)

Serum levels of antibody to pneumococcal vaccine were drawn 5 weeks after vaccination with 23-valent pneumococcal polysaccharide vaccine to assess humoral immune response. A positive response to the pneumococcal vaccine was defined as a 2-fold increase in serum antibody titers from Baseline or an increase of \> 1 mg/L from Baseline levels.

The 12 serotypes evaluated were pneumococcal serotypes 1, 3, 4, 6B, 7F, 8, 9N, 12F, 14, 18C, 19F and 23F.

Number of Participants With Adverse Events Through Week 88 weeks

An adverse event (AE) is any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. A Serious Adverse Event (SAE) is any AE that is fatal or is life-threatening, requires in-patient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, or is medically significant or requires intervention to prevent one or other of the outcomes listed above.
