Brief Summary:
This was a multinational, open-label study to assess the efficacy and safety of AVR-RD-01 in approximately 15 male subjects, who were 16 years of age or older and postpubertal with a confirmed diagnosis of classic Fabry disease based on deficient alpha galactosidase A (AGA) enzyme activity who were considered treatment naïve, i.e., had not previously received treatment with enzyme replacement therapy (ERT) and/or chaperone therapy within 3 years of the time of Screening.
Detailed Description:
The duration of each subject's participation in this study was approximately 64 weeks (or 1 year, 12 weeks), comprised of five study periods (Screening, Baseline, Pre-transplant, Transplant, and Post-transplant Follow-up). During the Screening Period (approximately 8 weeks), written informed consent (and assent, if applicable) was obtained and the subject had completed other Screening procedures to confirm study eligibility. Once study eligibility was confirmed, the subjects entered the Baseline Period (up to 3 days) during which time assessments would have been performed to establish a pre-transplant baseline. Once baseline assessments were completed, the subject entered the Pre-transplant Period (approximately 6 weeks) during which time mobilization, apheresis, AVR-RD-01 investigational drug product preparation and testing for release, and conditioning regimen administration to achieve myeloablation took place. Following completion of the Pre-transplant Period, the subject entered the Transplant Period (1 day) during which time AVR-RD-01 infusion took place. After AVR-RD-01 infusion, the subject entered the Post-transplant Follow-up Period (approximately 48 weeks), during which time periodic safety and efficacy assessments were performed to assess measures of engraftment, clinical response, and safety post-transplant.
In January 2022, the study was terminated early due to a decision by the study sponsor, to deprioritize its Fabry disease development program, and therefore, some subjects (n=5) did not complete the study (i.e., Week 48). Subsequently, in August 2023, the long-term follow-up study (AVRO-RD-01-LTF01), was also terminated early due to the decision by the sponsor to terminate the development program for Fabry disease, and therefore, no subjects completed the 15-year long-term follow-up study. This decision to terminate was not based on any safety or medical reasons.
