Specific guidelines that determine who can or cannot participate in a clinical trial
Must have
Diagnosis of either clinico-pathologically defined IBM, clinically defined IBM, or probable IBM according to the European Neuromuscular Centre (ENMC) IBM 2011 research diagnostic criteria (Rose et al., 2013). Documented histopathology results must be available prior to Baseline (Day 1) to confirm eligibility

Study Summary

This trial tests a new drug to see if it can treat Inclusion Body Myositis, a muscle disorder. It is a big, carefully designed study to see how safe and effective the drug is.

Who is the study for?
This trial is for adults over 40 with Inclusion Body Myositis who can walk and rise from a chair unassisted. They must weigh between 40-150 kg and meet specific diagnostic criteria. Excluded are those with other myopathies, severe arthritis affecting assessments, or autoimmune diseases like lupus or rheumatoid arthritis.Check my eligibility
What is being tested?
The study tests ABC008's effectiveness and safety in treating Inclusion Body Myositis. Participants will be randomly assigned to receive either ABC008 or a placebo without knowing which one they're getting (double-blind).See study design
What are the potential side effects?
Potential side effects of ABC008 aren't specified here but typically include reactions at the injection site, general discomfort, possible immune system responses, or other drug-specific effects that would be monitored throughout the trial.

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
Part A - To determine the safety and tolerability of recurrent dosing of ABC008 in subjects with IBM at 2 SC dose levels.
Part B - To determine the efficacy of ABC008 in IBM at two SC dose levels as measured by IBM Functional Rating Scale (IBMFRS) at Week (W)76
Secondary outcome measures
Part A - Adverse Events of Special Interest (AESI)
Part A - Clinically significant changes in standard laboratory parameters, vital signs, and ECGs
Part A - Treatment Emergent Adverse Events (TEAEs) onset within 24 hours of Study Medication Administration.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Are there vacancies available for participants in this research?

"Per the records available on clinicaltrials.gov, this trial is still searching for enrollees. The initial publication of the research was February 28th 2023 with a subsequent update occurring March 8th in the same year."

Answered by AI

How many healthcare centers are participating in the trial currently?

"Nine clinical trial sites, including those located in New Haven, Boston and New york are currently participating. Prospective participants should prioritize the closest location to minimize required travelling for their participation."

Answered by AI

What is the aggregate number of participants involved with this trial?

"Abcuro, Inc., the trial sponsor, intends to enroll 231 eligible patients at two of its sites: Yale School of Medicine in New Haven and Neuromuscular Diagnostic Center - Massachusetts General Hospital in Boston."

Answered by AI

What is the aim of this clinical experiment?

"From baseline to the end of the trial, which will last approximately 76 weeks, researchers are primarily interested in assessing ABC008's safety and tolerability when taken recurrently by IBM patients at two dose levels. Secondary objectives include measuring changes in quadriceps strength via dynamometry, recording treatment-emergent adverse events within 24 hours post-administration of study medications, and counting occurrences of side effects that necessitate discontinuation from the trial."

I am looking for help in slowing or curing this disease. At this time there is no action that one can take to delay or improve symptoms.
PatientReceived 2+ prior treatments
Diagnosed with IBM 8 years ago. Live in Tampa and Jacksonville is driving distance.
PatientReceived no prior treatments
I have been dealing with IBM a number of years. It was Penn that first diagnosed my IBM, but at that time Penn had no specialists looking into IBM. I transferred doctors to John Hopkins. I am a Penn heart transplant patient.
