Details and patient eligibility

About

Rheumatoid arthritis (RA) affects 1 percent of the population worldwide and up to 40 percent of patients don't respond to current treatments. MBS2320, the drug being tested in this trial, represents a new approach to treating RA, with the potential not only to reduce levels of inflammation but to also directly inhibit bone damage.The aim of this study is to test the safety of MBS2320 in healthy volunteers, to find out how MBS2320 levels change in the blood with dose, and to test the safety and compatibility of giving MBS2320 to patients with RA in combination with an existing treatment, methotrexate.

Full description

The study will be conducted in 4 parts (parts A to D). The principal aim of this study is to obtain safety and tolerability data when MBS2320 is administered orally as single and multiple doses to healthy subjects (parts A to C). The effect of MBS2320 on the pharmacokinetics (PK) of the first-line rheumatoid arthritis (RA) therapy, methotrexate (MTX), and the effect of MTX on the PK of MBS2320, will also be evaluated in a cohort consisting of subjects with RA (Part D).

Enrollment: 105 patients

Sex: All

Ages: 18 to 70 years old

Volunteers: Accepts Healthy Volunteers
