Study Evaluating Multiple Ascending Doses Of ATN-103 In Japanese Subjects With Rheumatoid Arthritis

September 3, 2013 updated by: Ablynx

A Randomized, Multicenter, Double-Blind, Placebo-Controlled, Multiple Ascending Dose Study Of The Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, And Clinical Efficacy Of ATN-103 Administered To Japanese Subjects With Active Rheumatoid Arthritis On A Background Of Methotrexate

This primary purpose of this study is to evaluate the safety, tolerability, and pharmacokinetic properties of multiple ascending doses of ATN-103 administered subcutaneously (below the skin) to Japanese subjects with active rheumatoid arthritis and on a stable background of methotrexate. Some subjects will receive ATN-103 while other subjects will receive a placebo.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

16 years to 71 years (Adult, Older Adult)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Safety and tolerability will be evaluated on the basis of AEs, SAEs,(including injection site reactions and infections), physical examination findings, vital sign, measurements, immunogenicity assessments, early termination, and clinical laboratory test.
Time Frame: 20 weeks
20 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Clinical efficacy for Rheumatoid Arthritis (RA) based on ACR responses, ACR-N, DAS 28 and EULAR response.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
