Safety, Tolerance, Pharmacokinetics and Activity of HE3286 in Patients With Rheumatoid Arthritis

Phase 1

Completed

• Conditions: Rheumatoid Arthritis
• Interventions: Drug: HE3286

• Registration Number: NCT00712114
• Lead Sponsor: Harbor Therapeutics

Brief Summary

The purpose of this pilot, exploratory study is to evaluate the safety, tolerance, pharmacokinetics and potential anti-inflammatory activity of an investigational agent, HE3286, when administered orally for 29 days to patients with rheumatoid arthritis that are taking a stable dose of methotrexate.

Detailed Description

This is a Phase I/II, open label, dose ranging study of the safety, tolerance, and anti-inflammatory activity of HE3286 in patients with rheumatoid arthritis. Patients will receive study treatment (one of three open label doses) in addition to their current stable dose of methotrexate. Safety (via monitoring of vital signs, physical examination changes, ECG results, laboratory results, and adverse events), pharmacokinetics profiles (of HE3286 and methotrexate) and anti-inflammatory activity will be assessed over a treatment period of 29 days.

Recruitment & Eligibility

• Status: COMPLETED
• Sex: All
• Target Recruitment: 14

Inclusion Criteria

• Male or female patient 18-75 years of age
• Patient with stable or active disease on a stable dose of methotrexate for at least 30 days prior to Day 1
• Patient has normal thyroid stimulating hormone (TSH) levels with or without thyroid replacement therapy
• Patient is willing to abstain from consuming grapefruit containing products from 24 hours prior to dosing until the end of the study as it may affect the pharmacokinetic measurements

• Patient with active Tuberculosis (TB) or evidence of latent TB without previous adequate therapy

• Systemic autoimmune disorder (including, but not limited to, systemic lupus erythematosus, inflammatory bowel disease, scleroderma, inflammatory myopathy, mixed connective tissue disease or any overlap syndrome)

• Inflammatory joint disease other than RA

• Patient who has received any of the following immunosuppressive drugs:

  • Etanercept within 1 month of Day 1;
