R-2487 in Patients With Rheumatoid Arthritis (R-2487-RA01)

A Single and Repeat Dosing Study of the Safety, Drug Exposure and Clinical Activity of R-2487 in Patients With Rheumatoid Arthritis

The goal of this study is to determine the safety and tolerability of orally taken probiotic (R-2487) in patients with Rheumatoid Arthritis.

Patients will take an oral dosage of probiotic (R-2487) and physicians will assess and measure their Rheumatoid Arthritis. Blood and fecal evaluations of inflammation and assessment of probiotic (R-2487) on fecal level will also be measured.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Incidence and severity of adverse events and their relationship to R-2487 (probiotic) administration	To assess the number of participants with treatment-related adverse events after taking R-2487 (probiotic)	Baseline through week 4

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in Disease Activity Score-28 Joint C-Reactive Protein (DAS28-CRP)	Change from Baseline in Disease Activity Score-28 joint C- Reactive Protein (DAS28-CRP) Score at Week 6 Describes severity of rheumatoid arthritis using clinical and laboratory data in swollen and tender joints. A score between 0 to 10 with the higher number indicating more active disease.	Baseline through week 4
Change in Simplified Disease Activity Index (SDAI) Score over time	Baseline Simplified Disease Activity Index (SDAI) Score over time. The Simplified Disease Activity Index (SDAI) is the numerical sum of five outcome parameters: tender and swollen joint count (based on a 28-joint assessment), patient and physician global assessment of disease activity [visual analogue scale (VAS) 0-10 cm] and level of C-reactive protein (mg/dl, normal <1 mg/dl).	Baseline through week 4
