Protocol summary

Study aim
Evaluation of the effects of supplementation extract prepared from Capparis spinosa on clinical manifestations, para-clinical and immunological factors in patients with refractory rheumatoid arthritis.
Design
Thirty patients with refractory rheumatoid arthritis will be randomly divided into three groups based on a table of random numbers in this phase 2-3 clinical trial. Randomization will be performed by block randomization, using online random number generator. Patients in group 1 will be treated by extract prepared from Capparis spinosa. Patients in group will be treated by placebo and group 3 will be treated by conventional therapy. Patients, outcome assessor and data analyser will be blinded in this study.
Settings and conduct
Thirty patients with rheumatoid arthritis patients who are refractory to standard therapies will be enrolled in this study. All patients will be recruited at rheumatology ward in the Imam Reza Hospital, Mashhad University of Medical Sciences, Mashhad, Iran. Patients will be randomly divided into three groups. Patients in group 1 will be treated by extract prepared from Capparis spinosa. Patients in group will be treated by placebo and group 3 will be treated by conventional therapy. Patients, outcome assessor and data analyser will be blinded in this study.
Participants/Inclusion and exclusion criteria
Inclusion criteria: Resistant rheumatoid arthritis (RA) patients to non-biological disease-modifying anti-rheumatic drugs (DMARDs) Exclusion criteria: Non-resistant RA patients to DMARDs
Intervention groups
Group 1: Refractory rheumatoid arthritis (RA) patients will be treated by extract prepared from Capparis spinosa. Group 2: Refractory RA patients will be treated by placebo. Group 3: Refractory RA patients will be treated by conventional therapy.
Main outcome variables
Clinical manifestations; para-clinical and immunological factors

Randomization (investigator's opinion)
Randomized
Randomization description
Thirty patients with rheumatoid arthritis who are refractory to standard therapies will be enrolled in this study. The patients will be randomized into three groups (10 patients in each group), group A (Capparis spinosa), group B (Placebo) and group C (Conventional therapy) based on a table of random numbers. Randomization will be performed by block randomization, using online random number generator (Sealed Envelope) https://www.sealedenvelope.com/simple-randomiser/v1/lists. An independent researcher will perform randomization in blocks using an online random number generator. The pharmacist will fill pill containers with each medication (Capparis spinosa or placebo) and will place them into sequentially numbered sealed envelopes in the order determined by randomization. The tools and materials needed to make the placebo will be exactly the same as the medicine except that only the active ingredient is removed from the placebo.
Blinding (investigator's opinion)
Double blinded
Blinding description
In this study the patients will be unaware of the group which they have been allocated in. Drugs have no label thus patients will not be aware of the type of treatment they receive. In addition, the outcome assessor and data analyser will not be aware of the type of intervention.
