What side effects are associated with this type of intervention?

Common treatments for Limb-Girdle Muscular Dystrophy (LGMD) that target genetic or molecular pathology, such as gene therapy or antisense oligonucleotides, can have side effects including immune reactions (fever, chills, severe immune responses), off-target effects (muscle weakness, fatigue), and potential long-term risks like organ toxicity or malignancy. These treatments aim to correct or mitigate the genetic defects causing the disease but require careful monitoring for adverse effects.

What prior FDA approvals exist?

As of now, there are no specific FDA-approved treatments for Limb-Girdle Muscular Dystrophy (LGMD) that target the genetic or molecular pathology of the disease, such as LGMD2I/R9. However, investigational therapies like AB-1003, which involve gene therapy or molecular approaches, are being studied to address the underlying genetic defects. These approaches are similar to treatments being explored for other muscular dystrophies, such as eteplirsen for Duchenne Muscular Dystrophy, which aims to increase dystrophin production through exon skipping. The field is actively researching and developing new therapies that target the genetic causes of these conditions.

What other types of research exist?

Promising novel alternatives to AB-1003 for LGMD2I/R9 patients include gene therapies such as SRP-9003, which targets the genetic mutations causing the disease. Additionally, CRISPR-Cas9 based gene editing therapies are being explored for their potential to correct genetic defects at the DNA level. Other molecular therapies, such as antisense oligonucleotides, are also under investigation for their ability to modulate gene expression and improve muscle function. Patients should discuss these options with their healthcare provider to determine the most appropriate treatment based on the latest research and clinical trial availability.

Gene Therapy

LION-101 for Limb-Girdle Muscular Dystrophy

Q: What is the mechanism of action of this treatment?

The most common treatments for Limb-Girdle Muscular Dystrophy (LGMD), particularly those targeting genetic or molecular pathology like AB-1003, often involve gene therapy and molecular interventions. These treatments aim to correct or compensate for the defective genes responsible for the disease. For instance, gene therapy may introduce a functional copy of the mutated gene, while molecular therapies might enhance the expression of compensatory proteins or inhibit pathways that lead to muscle degradation. These approaches are crucial for LGMD patients as they address the root cause of muscle weakness and degeneration, potentially improving muscle function and slowing disease progression.

Study Summary

This trial tests if a new drug is safe & tolerable for adults with a specific type of muscular dystrophy. It will be studied in sequential groups at different dose levels.

Who is the study for?

This trial is for adults aged 18-65 with a confirmed diagnosis of LGMD2I/R9 due to FKRP gene mutation. Participants should be able to climb stairs and walk 10 meters within specific times, understand study procedures, and use barrier contraception if sexually active. Exclusions include significant heart issues, MRI contraindications, other clinical trial participation, certain antibody levels, pregnancy or breastfeeding women, liver/renal diseases, cancer history in the last 5 years (except some skin cancers), and those needing ventilatory support.Check my eligibility

What is being tested?

The study tests the safety of LION-101 in treating limb girdle muscular dystrophy type 2I/R9 through a single intravenous infusion. It's conducted in sequential groups receiving different doses of LION-101 versus placebo to determine tolerability.See study design

What are the potential side effects?

While not explicitly listed here, potential side effects may include reactions at the infusion site such as pain or swelling; general symptoms like fever or chills; allergic reactions; and possibly effects on muscle tissue where the drug acts.
