A Study to Understand How the Study Medicine (PF-06823859) Works in People With Active Idiopathic Inflammatory Myopathies [Dermatomyositis (DM) and Polymyositis (PM)]
Description

The purpose of the study is to understand how the study medicine PF-06823859 works in people with idiopathic inflammatory myopathies (DM and PM). These disorders cause inflammation that weakens the muscles that are important for movement and may also cause skin rash in people with DM. This study is seeking participants who: * Are 18 years of age or older or minimum legal adult age as defined per local regulation, whichever is greater * Have active DM or active PM. * Are receiving a stable dose of 1 corticosteroid taken by mouth and/or 1 traditional immunosuppressant. * Note: Corticosteroids and immunosuppressants are medicines that help reduce inflammation and may signal to the immune system not to attack the body. Dermatomyositis (DM) is a rare disease that causes muscle inflammation that results in muscle weakness and low muscle stamina. Patients with DM have a characteristic skin rash. Polymyositis (PM) is a rare disease that involves mainly muscle inflammation resulting in muscle weakness, that can sometimes be painful. Patients with DM and PM may have trouble going up the steps, walking or getting to a standing position. Some of the participants will receive the study medicine (PF-06823859) and some will receive placebo (which is similar to study medicine but contains no medicine in it). The study medicine or placebo will be given as an intravenous (IV) infusion (directly into the veins), which takes about1 hour; every 4 weeks from Day 1 to Week 48 of the study. Both PF-06823859 and placebo and will be given at the study site. The study will compare the experiences of people receiving study medication to those of the people who do not. This will help to see if PF-06823859 is safe and effective. Participants will take part in this study for about 13 months. During this time, participants will have 15 study visits. These visits will be performed at the study site.

Environmental Risk Factors for Myositis in Military Personnel
Description

Background: * Myositis is a rare disease in which the body s immune cells attack the muscle tissue. It can cause muscle weakness, swelling, and pain. It can develop in people with no history of muscle problems. Environmental exposures may determine who develops myositis. Genes may also affect development of the disease. * Some people who serve in the military develop myositis. However, other military personnel do not. Researchers want to compare military personnel with and without myositis. They will look for common factors that might have led to the disease. Objectives: - To study environmental risk factors for myositis in military personnel. Eligibility: * Military personnel who developed myositis during their period of service. * Healthy military personnel who do not have myositis or another autoimmune disease. Design: * Participants will have a physical exam and medical history. * Participants will fill out forms about environmental exposures, particularly while in the military. The questions will ask about past infections, vaccines and medications, and personal habits. They will also ask about participants occupations during military service and their deployments. * Participants will also provide blood samples for study. * No treatment will be provided as part of this study.

Lithium in Inclusion Body Myositis (IBM)
Description

IBM is the most common acquired muscle disease occurring over the age of 50. The underlying cause remains unknown and there is currently no effective treatment. Pathological studies have revealed abnormal collections of proteins in the muscle cells from patients with IBM. These include proteins called phosphorylated tau (p-tau). A similar process appears to occur in Alzheimer disease, with accumulations of p-tau developing in brain cells. Lithium decreases the activity of the GSK, an enzyme that has a key role in the development of p-tau. Lithium and other GSK inhibitors have been shown to decrease the accumulation of p-tau in nerve cells in animal models of Alzheimer disease. The proposed research is a pilot study to see if lithium might be an effective treatment for IBM

Alemtuzumab to Treat Sporadic Inclusion Body Myositis
Description

This study will examine the safety and effectiveness of alemtuzumab (Campath® (Registered Trademark)) for improving muscle strength in patients with sporadic inclusion body myositis (s-IBM). The most common inflammatory muscle disease in people over the age of 50, s-IBM progresses steadily, leading to severe weakness and wasting of the muscles in the arms and legs. The cause of s-IBM is not known, but it may be an autoimmune disease, in which the body's immune cells (white blood cells) attack and destroy parts of muscle. Alemtuzumab is a laboratory-made antibody currently approved to treat certain leukemias. It has also been used to treat patients with autoimmune conditions such as rheumatoid arthritis, vasculitis, multiple sclerosis, and tissue rejection associated with transplantation. Alemtuzumab destroys white blood cells that have a protein called CD52 on their surface and that might be among the cells attacking muscle. Patients with s-IBM are eligible for this study. Candidates are screened with physical and neurological examinations, blood tests, and an electrocardiogram. Participants undergo the following tests and procedures: * Campath administration: Patients are admitted to the NIH Clinical Center for 1 to 1-1/2 weeks for intravenous infusions of Campath, given every other day for a total of 4 infusions. * Follow-up visits after infusions: Patients are monitored for up to 1 year with periodic blood tests, physical and neurological examinations, medical history, muscle strength measurements, and a review of symptoms, including the ability to perform daily living activities. * Lymphapheresis: Patients undergo this procedure for collecting large numbers of white blood cells twice - once at the beginning of the study and again after 6 months. Blood is removed through a needle in an arm vein and flows through a machine that separates it into its components by centrifugation (spinning). The white cells and plasma are removed and the red cells and platelets are returned to the patients through the same needle or through another needle in the other arm. * Muscle biopsy: Muscle biopsies are done in the operating room under local anesthetic. A small incision is made in the thigh or upper arm and a small piece of muscle is removed. Biopsies are done at the beginning of the study and again after 6 months.

Immune Abnormalities in Sporadic Inclusion Body Myositis
Description

This study will examine the abnormal immune response in patients with sporadic inclusion body myositis (s-IBM)-the most common inflammatory muscle disease in people over the age of 50. s-IBM progresses steadily and may lead to severe weakness and wasting of arm and leg muscles. Patients may become unable to perform daily living activities and be confined to wheelchairs. s-IBM is thought to be an autoimmune disease, in which the body's own immune system attacks healthy muscles. This study will explore the causes of the muscle tissue inflammation that is responsible for destruction of muscle fibers and weakness in this disease. Information from the study may help in the development of an effective treatment for this disease. Patients with s-IBM may be eligible for this study. Those who are unable to travel or who have severe cardiovascular, renal or other end-stage organ disease will be excluded. Candidates will be screened for eligibility with a medical history and physical and neurological examinations. Participants will be seen at the NIH Clinical Center every six months over a 12-month period (visits at enrollment, 6 months and 12 months) either on an inpatient or outpatient basis, depending on their disease severity. Each 2- to 3-day visit will involve the following tests and evaluations: * Blood samples for routine laboratory tests are collected at every visit. Additional blood for research studies is collected at 12 months. * Quantitative muscle strength testing is done at every visit. The patient pulls against straps connected to dynamometers (devices that measure muscle power) to evaluate strength of the main muscle groups in the arms and legs. * Lymphapheresis is done at enrollment and at 12 months. This is a procedure for collecting quantities of lymphocytes (white blood cells that are an important part of the immune system). Blood is collected through a needle placed in an arm vein and circulated through a machine that spins it, separating it into its components. The lymphocytes are removed and the rest of the blood (red cells, platelets and plasma) is returned to the body through the same needle or another needle placed in the other arm. * Electrophysiologic studies (electromyography and nerve conduction testing) are done at enrollment and 12 months. Electromyography evaluates the electrical activity of muscles. A small needle is inserted into the muscle and the patient is asked to relax or to contract the muscle. For nerve conduction testing, nerves are stimulated by electrodes (small wires taped to the skin over the muscle). * Muscle biopsy is done at enrollment and 12 months. A sample of muscle tissue (about the size of a lima bean) from an arm or leg is surgically removed to confirm the diagnosis of s-IBM and for analysis of proteins involved in the muscle inflammation process. A local anesthetic is used to numb the area before the surgery and the wound is closed with stitches.

A Study to Understand How the Study Medicine Dazukibart Works in People With Idiopathic Inflammatory Myopathies
Description

The purpose of this study is to understand how the study medicine, dazukibart, works in people with active idiopathic inflammatory myopathies (dermatomyositis \[DM\] or polymyositis \[PM\]). Idiopathic inflammatory myopathies are a group of disorders that show inflammation of the muscles used for movement. There are several types of idiopathic inflammatory myopathies, including DM and PM. DM and PM involve weakness of the muscles closest to the center of the body, such as the muscles of the hips, thighs, upper arms, and neck. People with these forms of idiopathic inflammatory myopathies may find it difficult to climb stairs, get up from a seated position, or lift items above their head. People with DM can also have a skin rash. These disorders negatively impact the quality of life and functioning of patients. In addition to the above, these disorders can affect how the lungs and heart work. This study is seeking participants who took part in a DM and PM study with dazukibart before. Some participants will receive study medicine, and some participants will not receive study medicine and only complete safety follow-up. The study medicine will be given as an intravenous (IV) infusion (directly into the veins). This takes about 1 hour, every 4 weeks, from Day 1 to Week 48 (about 12 months) of the study. This will be followed by a safety follow-up period that lasts about 4 months after the last infusion. Participants who receive study medicine will have about 18 study visits at the site over about 16 months. There will also be participants enrolled in this study who will not receive study medicine. Such participants will only take part in safety follow-up visits as they do not want to or are not eligible to receive dazukibart. These participants will not receive study medicine and will have up to 4 study visits at the site every 4 weeks to complete safety follow-up.
