Filter by:This is a prospective natural history study on patients with clinically defined sIBM. Participants will be assessed every 6 months over two years (five visits total). We will include 150 participants, enrolled across 13 sites, with sporadic IBM, diagnosed according to established criteria.
This is a pilot study (phase 1 clinical trial) to evaluate the safety and tolerability of phenylbutyrate in IBM. In this open label study, 10 patients with sporadic inclusion body myositis will be treated with phenylbutyrate (3 gm twice daily) for 3 months. There will be a run-in period, during which certain biomarkers will be measured at baseline and at the end of the run-in period in addition to final measurement at the end of the treatment period.

Sporadic inclusion body myositis (sIBM) is a rare idiopathic inflammatory myopathy characterized by chronic proximal leg and distal arm asymmetric muscle weakness. Its prevalence is estimated between 10 and 100 cases per million, over the age of 50. Little is known about the natural course of the disease, the delay between onset and diagnosis, the patterns of disease management and treatment in routine practice, as well as the burden for patients. The objectives of the PGRx-sIBM study will be to describe: - The epidemiology of the disease (estimation of the prevalence, age at onset, delay between onset and diagnosis, diagnosis process, etc.) - The patterns of disease management and treatment in routine practice - The burden of the disease for patients and their informal caregiver, as well as the quality of life of patients - The burden of the disease for informal caregivers This will be an observational (non-interventional), cross-sectional (transversal) study. Study setting The PGRx-sIBM will take place in France, Italy, Switzerland and Spain. Recruitment centers will be public and private practices and hospitals from urban or rural areas. In each recruitment center, at least one physician will act as a study investigator, in charge of identifying and recruiting patients. Inclusion of patients Patients will be included by their specialized physician (neurologist, Internal Medicine) during a regular outpatient visit, provided that they meet the following inclusion criteria: - The patient has been diagnosed with sIBM, as per the physician judgement and regardless of the date of diagnosis - Male or female - Age ≥ 45 years old - The patient does regularly live in the country of inclusion - The patient or his/her proxy can read and respond to a telephone interview - The patient agrees to participate Exclusion criteria will be: - The patient refuses to participate or the written Consent Form is not signed - The patient or his/her proxy cannot be reached by telephone. All eligible patients will be invited to participate in the study, during a 3 to 6-month period of time. The target sample size will be of 190 patients (≈15-20 in Switzerland, ≈50 in Spain, ≈50 in Italy and ≈70-75 in France).
This extension study will provide data to further evaluate the efficacy, safety, and tolerability of three doses of BYM338 and to assess the long-term effects of BYM338 in patients with sporadic inclusion body myositis. The extension study was planned to consist of a Screening epoch (to assess patient eligibility), followed by a Treatment Period 1 epoch (double-blind and placebo-controlled), and a Treatment Period 2 epoch (open-label). A Post-treatment Follow-up (FUP) epoch was also planned for patients who discontinued prematurely. Patients who complete the core study and qualify for this extension study entered Treatment Period 1 and continued on the study drug to which they were randomized in the core study (either to one of the three bimagrumab doses (1 mg/kg, 3 mg/kg, and 10mg/kg) or placebo) during Treatment Period 1. Thus, Treatment Period 1 was double-blind and placebo-controlled. Participants were to continue in Treatment Period 1 until the dose with the best benefit-risk profile was determined from the core study data and selected (duration of Treatment Period 1 was estimated to be between 6 and 8 months). Once the dose with the best benefit-risk profile was selected, all participants (including those who were receiving placebo) were planned to enter Treatment Period 2 and switch to open-label treatment with bimagrumab at the selected dose. The core study has been completed but since the core study did not meet the primary end point (no bimagrumab dose was identified based on the core study efficacy results) the extension study was terminated as per protocol/sponsor's decision; therefore, no patients had entered Treatment Period 2. Instead, all patients were to return for the End of Treatment Period 1 (EOT1) visit at their next scheduled visit. As per protocol, all patients who discontinued study medication during Treatment Period 1 for any reason, including due to the study having been stopped as per protocol/sponsor's decision, were to have entered and complete the 6-month FUP after their EOT1 visit. Due to the nature of the design of the core and extension studies and termination of study medication in the extension study, the treatment duration for individual patients varied considerably. Consequently, the number of patients contributing data to the efficacy analyses at Week 104 and later timepoints was decreased.
This study evaluates the effects of a low-intensity blood-flow restricted exerciser protocol on patient reported physical function, in patients with sporadic inclusion body myositis. The study is designed as a parallel group randomized controlled trial with a treatment group and a control group.
This study evaluated the efficacy, safety and tolerability of multiple doses of bimagrumab/BYM338 vs placebo, when administered intravenously (i.v.), on physical function, muscle strength, and mobility in patients with sporadic inclusion body myositis (sIBM).
The investigators are performing a gene therapy clinical trial in Becker muscular dystrophy (BMD) and sporadic inclusion body myositis (sIBM) patients. Both of these conditions have an important common feature: loss of ability to walk because of weakness of the thigh muscles. The investigators plan to do a gene therapy trial to deliver a gene to muscle called follistatin (FS344) that can build muscle size and strength. If successful, the investigators can increase the size of the thigh muscle and potentially prolong a patient's ability to walk. The gene will be carried into the muscle by a virus called adeno-associated virus (AAV). This virus occurs naturally in muscle and does not cause any human disease, setting the stage for its safe use in a clinical trial. Presently there is no treatment that can reverse Becker muscular dystrophy or sporadic inclusion body myositis. Only supportive care is currently possible. In this study, subjects with either of these diseases will have shots of the follistatin gene injected directly into thigh muscle on one (first cohort) or both legs (2nd and 3rd cohort). One hundred and eighty days following the gene delivery, the muscle will undergo biopsy to look closely at the muscle to see if the muscle fibers are bigger. Between the time of the gene transfer and the muscle biopsy, patients will be carefully monitored for any side effects of the treatment. This will include an MRI of the thigh muscle before treatment and at day 180 following treatment. Blood and urine tests, as well as physical examination will be done on the subjects during the screening visit and on days 0, 1, 2, 7, 14, 30, 60, 90, and 180 to make sure that there are no side effects from the gene injections. Sutures will be removed 2 weeks post-biopsy. Additional blood samples will be collected at 9, 12, 18, and 24 months. Patients will be seen at the end of 1st and 2nd years for a physical exam, assessment of muscle strength and appropriate blood tests.
This study will assess the efficacy, safety and tolerability of BYM338 in patients with sporadic Inclusion Body Myositis
