A Trial to Evaluate the Safety and Tolerability of Namilumab (MT203) in Patients With Mild to Moderate Rheumatoid Arthritis (PRIORA)

2015年7月24日 更新者：Takeda

A Phase Ib Double-blind, Placebo-controlled, Randomized, Dose-escalating Trial to Investigate the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics and Efficacy of Repeated Subcutaneous Injections of MT203 in Patients With Mild to Moderate Rheumatoid Arthritis on Treatment With Methotrexate

The purpose of this trial is primarily to investigate the safety and tolerability of repeated subcutaneous injections of MT203 in patients with mild to moderate rheumatoid arthritis. Furthermore, the amount of MT203 in the blood will be measured and it will be investigated how the body responds to MT203 treatment and if MT203 is effective in the treatment of rheumatoid arthritis.

Number of Participants With Clinically Significant Physical Examination Findings
大体时间：From Day 1 Up to Day 118
The physical examination included body system assessments: eyes, head and neck (including thyroid), ears, nose and throat, lymph nodes, cardiovascular, lungs, mammae, abdomen (liver, spleen), genitals, limbs, central and peripheral nervous system, musculoskeletal system, skin & nails, mucosae.

Number of Participants Reporting One or More Treatment Emergent Adverse Events
大体时间：From Day 1 Up to Day 118
An Adverse Event (AE) was defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (eg, a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the use of a drug, whether or not it is considered related to the drug. A treatment-emergent adverse event (TEAE) is defined as an adverse event with an onset that occurs after receiving study drug.

Lower numbers were better. A negative change from Baseline indicated improvement.
