Details and patient eligibility

About

The study is to evaluate the safety, tolerability, and pharmacokinetic (PK) of multiple orally administered TCK-276 in both males and females with Rheumatoid Arthritis (RA).

Full description

This is a Phase 1, multi-center, double-blind, randomized, placebo-controlled, multiple ascending dose (MAD) study.

The study will consist of a Screening Visit (Days -1 to Day 10), Treatment duration (up to 11 days) and a Follow-up/end of treatment (EOT) visit.

This MAD study will consist of 4 cohorts of 8 patients (6 active treatment and 2 matching placebo, or a 3:1 ratio), each receiving an oral dose of TCK-276 or matching placebo for 7 days (once daily (QD) under fed condition). The first cohort will be divided into 2 subgroups to implement the sentinel dosing approach.

The study duration is approximately 42 days.

Enrollment: 32 patients

Sex: All

Ages: 18 to 64 years old

Volunteers: No Healthy Volunteers
