Specific guidelines that determine who can or cannot participate in a clinical trial

Must have

Participant has a body mass index range of 17.0 to 30.0 kg/m2

Participant has both a clinical diagnosis of Friedreich ataxia (FA) and a documented history of genetic diagnosis of FA with either a guanine-adenine-adenine (GAA) trinucleotide repeat (TNR) expansion in intron 1 of both gene for frataxin (FXN) alleles or a GAA TNR expansion of intron 1 of one FXN allele and a pathogenic variant in the other FXN allele

Summary

"This trial is testing a new treatment called ASP2016 in adults with Friedreich Ataxia who have heart problems. ASP2016 is given as a slow injection into a vein, along with pred

Who is the study for?

Adults with Friedreich Ataxia and associated heart disease can join this trial. They must be able to tolerate the treatment and agree to overnight clinic stays, regular visits, or home nurse visits. The study excludes those who might have complications from gene therapy or cannot undergo necessary tests like biopsies.

What is being tested?

The trial is testing ASP2016, a new gene therapy given as an infusion for treating heart problems in Friedreich Ataxia patients. It's being tested alongside prednisolone tablets to check safety and tolerance at different doses.

What are the potential side effects?

Possible side effects include reactions to the infusion of ASP2016, immune system responses despite taking prednisolone, discomfort from frequent testing procedures such as biopsies and scans, and general risks associated with invasive cardiac procedures.

Experimental Treatment

Group I: ASP2016Experimental Treatment2 Interventions

Participants will receive a single dose of ASP2016. Participants will also receive daily prednisolone beginning 1 day prior to ASP2016 dose and for at least 16 weeks after ASP2016 dose, in order to suppress the immune response to ASP2016.
