VACINA: Vaccination Against Pneumococcal in Naïve Abatacept Rheumatoid Arthritis Patients
Study Details
Study Description
Brief Summary
Is pneumococcal conjugate vaccine (which induces a T-dependent humoral response) more efficient than pneumococcal polysaccharide vaccine (which induces a T-independent humoral response) in RA patients treated with abatacept, biotherapy targeting T-cells? The investigator propose to conduct a prospective, multicenter (11 centers), randomized, open-label study.
The patients are going to be randomized in 2 groups: patients of the first group will be vaccinated with the polysaccharide pneumococcal vaccine (Pneumo23®/Pneumovax®) whereas patients of the second group will be vaccinated with conjugate pneumococcal vaccine (Prevenar13®).

Detailed Description
The study population will be all the RA patients between 18 and 85 years with instauration of a treatment by sub-cutaneous abatacept in association with methotrexate who agreed to participate to the study.
At the time of their inclusion, patients will be randomized for receiving either pneumococcal polysaccharide vaccine (PPSV) or pneumococcal conjugate vaccine (PCV).
The primary endpoint will be evaluated at one month after vaccination. The total of follow-up will be of 12 months.
For the patients of the group PCV, the prime-boost strategy will be applied in order to be in accordance with the current French recommendation and a revaccination at 2 months after the initial vaccine will be realized with PPSV.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Active Comparator: pneumococcal polysaccharide vaccine Patients are vaccinated vith Peumo23/Pneumovax on the first day. Abatacept started on frst day. |
Biological: pneumococcal polysaccharide vaccine
Vaccination with PPSV on first day. NB : PPSV vaccine Pneumo23 has been replaced in September 2017 by the equivalent vaccine Pneumovax because of the stop of commercialization of Pneumo23 in France by the pharmaceutical company.
Other Names:
Drug: Abatacept
Abatacept started on frst day

| Active Comparator: pneumococcal conjugate vaccine Patients are vaccinated with Prevenar13 on the first day, and with Pneumo23/Pneumovax two months later. Abatacept started on frst day. |

Outcome Measures
Primary Outcome Measures
- Humoral response comparison after vaccination (number of patient with at least a two-fold increase of the antibody titer for at least 3 of the 5 serotypes of interest : 1,3 14, 7F, 19A) [1 month after vaccination]
To compare the rate of responders, at one month after vaccination, between patients vaccinated with PCV and patient vaccinated with PPSV.
Secondary Outcome Measures
- Side Effect frequency (number of side effect at each patient's visit for both groups) [1, 2,6 ans 12 months after inclusion]
Comparison of the frequency of side effects between the 2 groups at 1, 2, 6 and 12 months
- Prime boost strategy efficacity evaluation (number of responder in the PCV group) [6 months after inclusion]
Calculation of the rate of responders, in the PCV group, at 4 month after re-vaccination by a dose of PPSV
- Long term immune response after vaccination [6 and 12 months after vaccination]
Comparison between the 2 groups of the rate of responders at 6 and 12 months after vaccination
- Comparison between the 2 groups of the opsonophagocytosis activity of the antibodies produced [1, 2, 6 and 12 months after vaccination]
Comparison between the 2 groups of the opsonophagocytic titers (OPA) at 1, 2, 6 and 12 months after vaccination
- Pneumococcal vaccination predictive factor identification [12 month after last patient inclusion]
Analysis of the collected date to search for predictive factors of immune response after pneumococcal vaccination by comparison of the rates of responders within each group, according to age, gender, RA activity, MTX dosage, corticosteroid, dosage, therapeutical history
