Generalized Myasthenia gravis (gMG) is a rare neuromuscular inflamation disorder that involve all voluntary muscle groups. This study is to evaluate the safety and efficacy of ravulizumab for the treatment of patients with generalized myasthenia gravis (gMG).
There will be 3 periods in this study; a 4 week Screening Period, a 26-week Randomized-Controlled Period consisting of 8 study visits, and an Open-Label Extension Period consisting of 17 visits that will continue for up to 2 years. Meningococcal vaccination is required for all patients prior to intravenous administration of study drug. The overall study duration for an individual participant is estimated to take up to 2.5 years.
The purpose of this study is to evaluate how safe and effective intravenous eculizumab is in pediatric patients 6 to less than 18 years old with generalized Myasthenia gravis (gMG). Eculizumab is already approved for use in adult patients with gMG in the US, Europe and Japan, but currently has not been approved for use in pediatric patients.
The study's duration is approximately 4.7 years with 4 treatment periods consisting of a Screening Period (2 to 4 weeks), Primary Evaluation Treatment Period (26 weeks), Extension Period (up to an additional 208 weeks), and Follow-up Period (8 weeks). All patients who complete Week 26 of Study ECU-MG-303 will continue receiving eculizumab in the Extension Period of this study for up to an additional 208 weeks.
This is a global phase 3 open-label study designed to evaluate the efficacy and safety of ALN-TTRSC02 in adult patients (18 - 85 years of age) with hATTR amyloidosis. The estimated time on the study is approximately 3 years, including 42 days of Screening, an 18 month Treatment Period and an 18 month Treatment Extension Period.
The primary objective of this study is to evaluate the efficacy of lenabasum compared to placebo in participants with dermatomyositis (DM), and to evaluate the safety and tolerability of lenabasum in participants with Dermatomyositis (DM).
Autoimmune diseases such as DN result from the immune system becoming over-active and attacking parts of the body. This over-active immune response also causes chronic inflammation. The growth of scar tissue in muscle, skin and internal organs with chronic inflammation from DM makes them not work as well as they should. Lenabasum may help the body stop the chronic inflammation and stop scarring fro getting worse without preventing the normal response of the immune system.
Lenabasum is an investigational drug that will be taken orally twice a day. It will take about one year to complete this research study. During this time, participants will make a total of 12 study visits.
This is an observational study to develop a research registry to collect information from subjects with Myasthenia Gravis (MG) to evaluate the effects of the treatments they receive and to understand how their medical condition and treatment affects their daily life.
