A Study To Evaluate the Pharmacokinetics, Pharmacodynamics, Safety and Tolerability of ASP2408 After Multiple Dose Subcutaneous Injections in Patients With Rheumatoid Arthritis on Methotrexate
- Conditions
- Pharmacokinetics of ASP2408Rheumatoid Arthritis
- Interventions
- Drug: Placebo
- Registration Number
- NCT02052375
- Lead Sponsor
- Astellas Pharma Global Development, Inc.
- Brief Summary
The purpose of this study is to assess the safety, tolerability and pharmacokinetics (PK) of two dosing regimens of multiple, subcutaneous (sc) injections of ASP2408 in patients with Rheumatoid Arthritis (RA) on Methotrexate (MTX) and to evaluate the pharmacodynamics (PD) of ASP2408.
- Detailed Description
This is an ascending dose frequency study. There are two cohorts of active and placebo patients. The first cohort is dosed every 4 weeks for a total of 3 doses. The second cohort is dosed every two weeks for a total of 3 doses.
