Trial Summary

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you must have been on enzyme replacement therapy (ERT) or substrate reduction therapy (SRT) for at least 2 years and on a stable dose for at least 3 months before joining. You cannot use GD-related chaperone therapy within 4 weeks before starting the trial.

How does the drug LY3884961 differ from other treatments for Gaucher Disease?

LY3884961 is a novel gene therapy approach for Gaucher Disease, which aims to address the root cause by delivering a functional copy of the GBA1 gene to cells, potentially offering a more long-term solution compared to existing enzyme replacement therapies that require regular infusions.12345

What is the purpose of this trial?

This trial tests a new drug called LY3884961 in adults with specific symptoms of Gaucher Disease. The study aims to find the safest and most effective dose by observing how patients' bodies react to different amounts of the drug. Researchers will monitor safety, side effects, and changes in disease symptoms over several years.

Findings from Research

The N370S allele is a key genetic marker for diagnosing type 1 Gaucher disease in the Ashkenazi Jewish population, while the L444P/L444P genotype is linked to more severe neuronopathic forms of the disease.
There is a significant underestimation of the prevalence of the N370S/N370S genotype in affected individuals, which has important implications for genetic counseling and understanding the disease's expression in patients.
Gaucher disease: gene frequencies and genotype/phenotype correlations.Grabowski, GA.[2022]
A novel mutation (V191G) in the glucocerebrosidase gene was identified in a patient with type 1 Gaucher disease, which may indicate a specific genetic profile affecting disease severity.
The presence of the N370S mutation alongside V191G suggests a potentially milder clinical course for this patient, as N370S is associated with less severe symptoms in type 1 Gaucher disease.
A novel mutation (V191G) in a German-British type 1 Gaucher disease patient. Mutations in brief no. 131. Online.Choy, FY., Humphries, ML., Ben-Yoseph, Y.[2013]
In a study of 46 patients with Gaucher's disease, 90% of type I patients had identifiable mutations, including a new recombinant mutation RecA456P, highlighting the genetic diversity of the disease.
The study found that the N370S mutation generally leads to milder adult-onset disease, but exceptions exist, indicating that genotype alone may not fully predict disease severity.
