What this Trial Is About

The goal of this clinical trial is to study the drug LPX-TI641 in patients with rheumatoid arthritis and psoriatic arthritis. We will compare the safety and tolerability of LPX-TI641 to placebo that contains no drug. We will also evaluate the plasma pharmacokinetics of LPX-TI641. LPX-TI641 (or placebo) will be administered orally for 28 days.
