Vaccination Against Pneumococcal in Naïve Abatacept Rheumatoid Arthritis Patients — VACINA  

Rheumatoid Arthritis Clinical Trial

Official title: Comparison of Humoral Response to Conjugate Pneumococcal Vaccine and Polysaccharide Pneumococcal Vaccine in Rheumatoid Arthritis (RA) Patients Treated With Abatacept

Status Completed

Clinical Trial 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®).

Clinical Trial 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. ;
