Systemic lupus erythematosus (SLE) also known as lupus is a complex autoimmune disorder where the immune system attacks itself instead of external pathogens that can cause disease like bacteria or viruses. The large majority of SLE patients are women. The purpose of this study is to better understand how SLE affects overall patient health in women and expression of genes linked to the development of SLE. Part of this study involves collection of a blood sample at a single visit to test expression of genes linked to SLE. This study will compare demographic and clinical characteristics and genetic differences among women with SLE from three racial/ethnic groups. Better understanding of racial/ethnic differences in health and genetic expression of SLE could help reduce poor disease outcomes such as kidney or heart disease. Results will help us learn more about differences in SLE health across different racial/ethnic backgrounds and will guide medical care.

The purpose of this research study is to see if IgPro10 (the study medication) is effective and tolerated when administered to adults with diffuse cutaneous systemic sclerosis (dcSSc) who have skin thickness involvement throughout their body. The study medication is administered intravenously through an IV. There are approximately 22 scheduled visits to the study site to complete assessments, in addition to a Follow-Up phone call. Your participation will last for approximately 80 weeks.

The purpose of this study is to evaluate use of a mobile application (also commonly referred to as an app) designed to support caregivers of children with newly diagnosed food allergy. This study has 2 phases. In Phase 1, the researchers obtained feedback regarding use of mobile apps from caregivers who have been managing their child's food allergy for one year or more. The researchers then used this feedback to build a mobile app for caregivers of children with newly diagnosed food allergy. In Phase 2, the researchers will evaluate the mobile app during a 4-week evaluation period with a group of caregivers of children newly diagnosed with food allergy. The data obtained from this study will hopefully benefit caregivers of children with newly diagnosed food allergy.

Myasthenia gravis is an autoimmune disease; a disease that occurs when the immune system attacks the body's own tissues. In generalized myasthenia gravis (gMG), that attack interrupts the connection between nerves and muscles; called the ‘neuromuscular junction.' This study is to study the safety, tolerability and efficacy of a study drug called Zilucoplan in adult participants with gMG.

Participation in this study will last approximately 16 weeks and will include approximately 7 study visits.

The purpose of this study is to find out more information about the study drug iloprost for the treatment of symptomatic Raynaud's phenomenon (RP) attacks in people with scleroderma. A Raynaud's attack is defined as one where you notice at least one color change of your finger(s) (blue, white, or red) associated with at least one symptom (pain, numbness, tingling, and/or discomfort of the finger[s]). Your participation in this study will last approximately 9 weeks and will include 8 visits to the study center and 1 phone call from the study staff.

KD025 is an investigational medication undergoing testing to determine if it may be effective in the treatment of diffuse systemic sclerosis (skin thickening on more than just the hands). KD025 has previously been tested in graft-versus-host disease, idiopathic pulmonary fibrosis, and psoriasis. It has shown preliminary effectiveness and safety in the treatment of these conditions. This study will randomly assign subjects to one of three treatment groups, 20mg of KD025 twice per day, 20mg of KD025 once per day, and placebo. The study will measure the improvement, stabilization or worsening of your symptoms, such as changes in your fatigue and pain levels, lung function, skin thickness and other patient reported outcomes. The study treatment period will last 1 year. The drug may help mitigate symptoms of systemic sclerosis and thus may be helpful with the disease in study. The population to be enrolled in this study will involve patients diagnosed with systemic sclerosis, diffuse subset, 18 years of age or older.

The study is using cemdisiran compared to placebo injections to determine the safety and efficay of cemdisiran in treating IgA Nephropathy. The study includes a screening period (up to 90 days), 8 month treating period, and 52 week Open Label extension period. Injections occur monthly during the treatment period. Patients will be randomized 2:1 to the cemdisiran or placebo arms.

The purpose of this research study is to evaluate the value of educational information given on an iPad about the risks and benefits of lupus medications. The information is intended to encourage conversations between the patient and doctor about lupus treatments. This research will test the feasibility and effectiveness of using the iPad in lupus clinics nationwide. Participants will be given information about lupus treatments on an iPad during the clinic visit before seeing their doctor and will be interviewed about the feasibility of using the iPad during a regular clinic visit.

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.
