Title

Safety and Tolerability Study of MBS2320 in Healthy Subjects and Subjects With Rheumatoid Arthritis
A Four-Part Phase-1 Study Investigating the Tolerability, Safety and Pharmacokinetics (PK) of MBS2320 in Healthy Subjects and in Subjects With Rheumatoid Arthritis (RA) Also Treated With Methotrexate

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.
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).

Drug MBS2320

As described in the arm descriptions

Drug Placebo

As described in the arm descriptions

Drug Methotrexate

Background therapy as described in the arm descriptions

  • Other names: Rheumatrex, Trexall, Amethoperin, Mexate

Single Ascending Dose and Food Effect Experimental

Part A will be a single-dose, sequential-group, double-blind, placebo-controlled study of MBS2320.

Multiple Ascending Dose Experimental

Part B will be a multiple-dose, sequential-group, double-blind, placebo-controlled study to investigate 3 planned dose levels.

Relative Bioavailability Experimental

Part C will be an open-label, randomised, 2-period crossover relative bioavailability study of MBS2320 in capsules or suspension. The intention is to enrol 8 healthy subjects. Each subject will participate in 2 treatment periods.

Drug-Drug Interaction with Methotrexate Experimental

Part D will be a multiple dose study incorporating an open-label, fixed-sequence drug-drug interaction between MBS2320 and methotrexate and biomarker evaluation.
