Patients with adult-onset rheumatoid arthritis will be enrolled. They will be dosed with repeated intravenous doses of BTT-1023 or placebo. During the trial, the safety of the treatments and the pharmacokinetics of BTT-1023 will be assessed. The patient allocation to treatment groups will occur at random, and the actual treatment will not be revealed to the investigator or to the patient during the trial.
This study is designed to provide safety and efficacy data to support the development of CP-690,550 in patients with moderate to severe rheumatoid arthritis on background of methotrexate.
Magnesium iron hydroxycarbonate is a phosphate binder that absorbs phosphate from food, reducing the amount that the body can absorb.

This grant involves 24 social networks of young men who have sex with men, Roma, and young high-risk heterosexual adult men and women living in Hungary, Bulgaria and Russia.
The primary objective of this study is to evaluate the long-term safety profile of BG00012 (dimethyl fumarate). Secondary objectives of this study are to evaluate the long-term efficacy of BG00012 using clinical endpoints and disability progression, to evaluate further the long-term effects of BG00012 on multiple sclerosis (MS) brain lesions on magnetic resonance imaging (MRI) scans in participants who had MRI scans as part of Studies 109MS301 (NCT00420212) and 109MS302 (NCT00451451) and to evaluate the long-term effects of BG00012 on health economics assessments and the visual function test.

This is a Phase III, randomized, multicenter, international, 2-arm, open-label clinical trial designed to compare the safety and efficacy of trastuzumab emtansine (T-DM1) with that of capecitabine + lapatinib for HER2-positive metastatic breast cancer (MBC). Patients were treated until disease progression, unmanageable toxicity, or study termination. Once disease progression was reported, all patients were followed for survival every 3 months until death, loss to follow-up, withdrawal of consent, or study termination.
