Trial Outcomes & Findings for Study to Compare the Efficacy and Safety of Oral AT1001 and Enzyme Replacement Therapy in Patients With Fabry Disease (NCT NCT01218659)

NCT ID: NCT01218659

Last Updated: 2018-11-01

Results Overview

To assess renal function, measured glomerular filtration rate (GFR) was measured by the plasma clearance of unlabeled iohexol (mGFR-iohexol), a non-ionic contrast agent. The annualized rate of change in mGFR-iohexol from Baseline to Month 18 was analyzed using an analysis of covariance (ANCOVA) model with the following factors as covariates: treatment group, sex, age, Baseline GFR (mGFR-iohexol), and Baseline 24-hour (hr) urine protein. A threshold of \<2.2 milliliter (mL)/minute (min)/1.73 meter squared (m\^2)/year was established to compare migalastat to ERT. This difference of 2.2 mL/min/1.73 m2/year is based on the smallest expected rate of decline in estimated glomerular filtration rate (eGFR) for participants treated with agalsidase alfa for 18 months.

Participant Flow

The All Migalastat group was comprised of participants who received migalastat during the randomized treatment period (0-18 mo.) and who received enzyme replacement therapy (ERT) during the randomized treatment period (0-18 mo.) and switched to migalastat during the 12-mo. open-label extension (OLE). 8 participants enrolled but did not randomize.

Participant milestones

Participant milestones
Measure
Migalastat (0-18 Months)
Participants received 150 milligrams (mg) of migalastat hydrochloride (migalastat) (equivalent to 123 mg of migalastat) orally once every other day (QOD) during the 18-month randomized treatment period (0-18 months). Participants received an inactive reminder capsule on alternate days during both treatment periods.
ERT (0-18 Months)
Participants received ERT (either agalsidase alfa or agalsidase beta) as prescribed by the participant's treating physician and administered in accordance with the approved prescribing information during the 18-month randomized treatment period (0-18 months). Participants were required to be given \>80% of the currently labeled dose and regimen during the 18-month randomized treatment period.
All Migalastat (0-30 Months)
Participants in this group are composed of participants from the Migalastat (0-18 months) and the ERT (0-18 months) groups. Therefore, participants in the All Migalastat group received at least 1 dose of 150 mg migalastat orally QOD during the 18-month randomization period or the optional 12-month OLE (for a total time period of up to 30 months), regardless of whether or not the participant discontinued the study early, and regardless of whether they were previously randomized to migalastat or ERT during the 18-month Randomized Period (0-18 months).

PRIMARY outcome

Timeframe: Baseline to Month 18

Population: mITT Population: All randomized participants with an α Gal-A mutation that is amenable to migalastat, based on the GLP HEK assay, who received at least 1 dose of study drug, had Baseline and postbaseline mGFR-iohexol values, and postbaseline measure of the estimated GFR using the CKD-EPI equation.

To assess renal function, measured glomerular filtration rate (GFR) was measured by the plasma clearance of unlabeled iohexol (mGFR-iohexol), a non-ionic contrast agent.

A threshold of \<2.2 milliliter (mL)/minute (min)/1.73 meter squared (m\^2)/year was established to compare migalastat to ERT.

Timeframe: Baseline to Month 18

Population: mITT Population: All randomized participants with an α Gal-A mutation that is amenable to migalastat, based on the GLP HEK assay, who received at least 1 dose of study drug, had Baseline and postbaseline mGFR-iohexol values, and postbaseline measure of the estimated GFR using the CKD-EPI equation.

The eGFR assessed by the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation was calculated using the following: eGFR-CKD-EPI = 141 x min (Serum Creatinine/κ,1)\^(α) x max(Serum Creatinine/κ,1)\^(-1.209) x 0.993\^(Age) x 1.1018 (if female) x 1.159 (if African American or black) where: κ is 0.7 for females and 0.9 for males; α is -0.329 for females and -0.411 for males; min indicates the minimum of Serum Creatinine/κ or 1; max indicates the maximum of Serum Creatinine/κ or 1. The annualized rate of change in eGFR-CKD-EPI from Baseline to Month 18 was analyzed using an ANCOVA model with the following factors as covariates: treatment group, sex, age, Baseline GFR (eGFR-CKD-EPI), and Baseline 24-hr urine protein. A threshold of \<2.2 mL/min/1.73m\^2/year was established to compare migalastat to ERT. This difference of 2.2 mL/min/1.73 m2/year is based on the smallest expected rate of decline in eGFR for participants treated with agalsidase alfa for 18 months.

Timeframe: Baseline to Month 18

Population: mITT Population: All randomized participants with an α Gal-A mutation that is amenable to migalastat, based on the GLP HEK assay, who received at least 1 dose of study drug, had Baseline and postbaseline mGFR-iohexol values, and postbaseline measure of the estimated GFR using the CKD-EPI equation.

The GFR estimated by the Modification Of Diet In Renal Disease equation (eGFR-MDRD) was calculated using the following equation: eGFR-MDRD = 175 x (Serum Creatinine)\^(-1.154) x (Age)\^(-0.203) x 1.212 (if participant's race is black or African American) x 0.742 (if participant is female). The eGFR-MDRD from Baseline to Month 18 was analyzed using an ANCOVA model with the following factors as covariates: treatment group, sex, age, Baseline GFR (eGFR-CKD-EPI), and Baseline 24-hr urine protein.

Migalastat (0-18 Months)
n=36 participants at risk
Participants received 150 mg of migalastat orally QOD during the 18-month randomized treatment period (0-18 months). Participants received an inactive reminder capsule on alternate days during both treatment periods.
ERT (0-18 Months)
n=21 participants at risk
Participants received ERT (either agalsidase alfa or agalsidase beta) as prescribed by the participant's treating physician and administered in accordance with the approved prescribing information during the 18-month randomized treatment period (0-18 months). Participants were required to be given \>80% of the currently labeled dose and regimen during the 18-month randomized treatment period.
All Migalastat (0-30 Months)
n=51 participants at risk
Participants in this group are composed of participants from the Migalastat (0-18 month) and the ERT (0-18 month) groups. Therefore, participants in the All Migalastat group received at least 1 dose of 150 mg migalastat orally QOD during the 18-month randomized treatment period or the optional 12-month OLE (for a total time period of up to 30 months), regardless of whether or not the participant discontinued the study early, and regardless of whether they were previously randomized to migalastat or ERT during the 18-month randomized phase (0-18 months).
