Trial Outcomes & Findings for A Study of AT1001 (Migalastat Hydrochloride) in Participants With Fabry Disease (NCT NCT00214500)

NCT ID: NCT00214500

Last Updated: 2018-10-30

Results Overview

TEAEs were defined as any adverse event with start date on or after administration of study drug or pre-existing conditions that worsened on or after the start of the first study drug administration (on Day 1). A severe adverse event was defined as an adverse event that was incapacitating and required medical intervention. The number of participants who experienced one or more severe TEAEs after dosing on Day 1 through Week 96 is presented. A summary of serious and all other non-serious adverse events regardless of causality is located in the Reported Adverse Events module.

PRIMARY outcome

Timeframe: Day 1 (after dosing) through Week 96

Population: Safety Population: all eligible-enrolled participants who received at least 1 dose of study drug. 6 participants were dosed screen failures, and were not included in the safety analysis.

TEAEs were defined as any adverse event with start date on or after administration of study drug or pre-existing conditions that worsened on or after the start of the first study drug administration (on Day 1). A severe adverse event was defined as an adverse event that was incapacitating and required medical intervention.

SECONDARY outcome

Timeframe: 0 (predose), 0.5, 1, 2, 3, 4, 5, 6, 8, and 10 hr (postdose)

Population: PK Population: all eligible-enrolled participants who received study drug and had at least 1 postbaseline PK parameter recorded. One participant discontinued prior to receiving doses of migalastat 100 and 250 mg.

The AUC from time zero to 12 hours (hr) postdose (AUC0-12) was evaluated in plasma following a single dose of migalastat 25, 100, and 250 mg on Days 1, 15, and 29, respectively. In addition, AUC0-12 was assessed following multiple doses (14 days) of migalastat 25, 100, and 250 mg on Days 14, 28, and 42, respectively.

SECONDARY outcome

Timeframe: Baseline, Week 12 (end of treatment period), Week 96 (end of extension period)

Population: PD Population: all eligible-enrolled participants who received at least 1 dose of study drug on Day 1, and who had a non-missing baseline and at least 1 non-missing postbaseline PD parameter recorded. Participants who discontinued prior to the specified time point were not analyzed because no data were available.

Leukocytes were isolated from whole blood and lysed, and α-Gal A activity was measured using a validated fluorometric assay, with catalysis to fluorescent 4-methylumbelliferone (4-MU) as the activity measure. The activity values obtained were normalized to protein (measured using a colorimetric assay) and reported as enzyme activity (nanomole \[nmol\] 4-MU/hr) per mg of protein. On Day 1 of the first visit and at every visit thereafter, the samples were collected prior to dosing with migalastat. α-Gal A activity in leukocytes are presented by individual participants.
