Why
  1. The study's listed conditions name Myositis, Inclusion Body, a narrower term within Myositis.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

A study looking at the effect of pioglitazone in skeletal muscle of patients with sporadic inclusion body myositis (sIBM).

Read the detailed description

This is a 52-week, Phase 1, open-label, single center, proof of concept study of FDA-approved pioglitazone in adult patients with sporadic inclusion body myositis (sIBM). The trial consists of a 4-week screening period;16-week "lead-in" period during which all subjects are observed off-treatment. At Week 16, all subjects will be started on pioglitazone at a dose of 30 mg daily. The dose will be uptitrated to a goal dose of 45 mg daily after 2 weeks; 32-week treatment period with all subjects on 45 mg daily dose of pioglitazone.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Age ≥ 50 years
  • Diagnosis of sporadic inclusion body myositis (sIBM) based on the sIBM Diagnostic Criteria established by the 2010 European Neuromuscular Center.
  • Must be able to ambulate at least 20 feet, with or without the use of an assistive device. Patients may not use another person, wall, or furniture for support.
  • Must be able to rise from a chair without support from another person or device.
  • Premenopausal women must have a negative serum pregnancy test prior to dosing with study medication.
  • Women of and men must agree to use adequate (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation.

Exclusion criteria

Exclusion Criteria:

  • A history of diabetes mellitus, or prior or concurrent treatment with any diabetes therapy
  • Use of chronic therapy including or intravenous immune globulin (IVIG) within the past 6 months.
  • Use of Vitamin E supplements within the past 3 months
  • Creatine kinase (CK) > 15x the
  • Any condition other than sIBM that causes significant muscle pain, muscle weakness, muscle atrophy, or joint pain. This includes but is not limited to such neurologic and neuromuscular diseases as polymyositis or dermatomyositis, myasthenia gravis, amyotrophic lateral sclerosis, stroke, multiple sclerosis, epilepsy, muscular dystrophy, fibromyalgia, rheumatoid arthritis, spinal cord injury or degenerative disease of the spine. Osteoarthritis is not exclusionary unless it limits the patient's ability to comply with study tasks. Patients with a history of a hip or vertebral fracture within the past year or surgical hip or knee replacement within the past six months will be excluded.
  • Patients receiving any medications or substances that are inhibitors or inducers of CYP2C8 are ineligible. These medications include but are not limited to Gemfibrozil, Rifampin, and warfarin.
  • Pregnant women
  • History of cancer less than five years prior, other than local basal or squamous cell cancer.
  • Patient has any medical condition or laboratory finding during screening, which, in the investigator's opinion may interfere with participation, confound the results, or pose any additional risk to the patient.
Terms in these criteria, in plain language(5)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 12, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
