Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 to 65 with a confirmed diagnosis of Fabry disease and cardiac involvement who are intolerant to or have had inadequate responses to existing enzyme replacement therapies.

Probably not a fit

Patients with severe kidney impairment, recent history of significant thromboembolic events, or those with contraindications to corticosteroid therapy may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a multicenter, open-label trial designed to evaluate the safety, tolerability, and pharmacodynamics of a single intravenous administration of 4D-310 in adults diagnosed with Fabry disease who also have cardiac involvement. The trial will involve dose escalation to determine the optimal dosage while monitoring participants for any adverse effects. The study population includes both male and female adults aged 18 to 65 years with specific genetic mutations associated with Fabry disease.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with Fabry disease who have cardiac complications.

How similar studies have gone: While there have been studies on Fabry disease treatments, the specific approach of using 4D-310 in this context is novel and has not been extensively tested in prior trials.
