The ENERGY study is for adults (ages 18 and up) with warm Autoimmune Hemolytic Anemia (wAIHA) who are currently receiving treatment or have previously received treatment. The goal of the study is to see if the study drug, Nipocalimab is safe and effective in the treatment of wAIHA. Nipocalimab is an investigational medication designed to stop your immune system from destroying your red blood cells.

You may be able to join the study if you are:

• 18 years of age or older
• Diagnosed with wAIHA for at least 3 months
• Currently receiving treatment or have previously received treatment for wAIHA
• Have platelet counts of more than 30,000/ L and Hemoglobin less than 10 g/dL

Other study requirements will apply.

Individuals with a certain type of beta thalassemia that is treated with regular transfusions, and who are 50 years old and younger, may be able to participate. A number of screening tests will be done to determine if subjects can participate. These include review of your past medical history, blood and urine tests, bone marrow aspirate/biopsy, bone age/ DEXA scan, heart ultrasound, electrocardiogram, magnetic resonance imaging (MRI) of the heart and liver, and liver biopsy. If eligible, blood stem cells will be collected by apheresis or by bone marrow harvest. These stem cells will then have a healthy beta globin gene inserted. You will then be hospitalized and chemotherapy will be given to empty out the bone marrow. The stem cells, with the inserted gene, will then be given back to you. You will be followed for side effects and to see if the inserted gene helps you make hemoglobin.

Immune Thrombocytopenia (ITP) is a blood disorder in which the immune system produces antibodies that attack and destroy the body's own blood platelets. The Panzyga Study is looking at a potential medicine (experimental drug) to see if it can result in increasing platelet counts and may potentially treat ITP. You will be infused with the experimental drug once or twice during the treatment period and will be followed up for 32 days. Testing will include blood tests, urine tests, pregnancy tests and physical exams. You may be able to take part in the study if you are below 18 years of age and have been diagnosed with chronic ITP.

This research study is seeking participants who have hemophilia B and need regular preventive treatment with factor IX protein (FIX) replacement therapy to prevent and also control bleeding events. To join the study , you must be male as assigned at birth, and between the ages of 16 and 65 years at the time of signing the informed consent form. The purpose of this study is to gather at least 6 months of information on bleeding events for each individual participant while they continue to use their usual FIX replacement therapy. There is no experimental drug or treatment being tested in this study. The study is informational, and part of a larger program to understand and treat hemophilia B with a potential experimental new therapy in the future. After participants complete this research study, should they be interested and eligible, they may be offered the opportunity to take part in a future study with this new therapy. There is no obligation to agree to taking part in this future study.
