Trial Outcomes & Findings for Study Evaluating ECG Effects, Safety, Tolerability and Pharmacokinetics of Single Doses of Modufolin (Arfolitixorin) in Healthy Volunteers Tetrahydrofolate in Healthy Male Volunteers (NCT NCT03203564)

NCT ID: NCT03203564

Last Updated: 2020-09-25

Results Overview

At each nominal time point specified in the CSP, up to 10 ECG replicates were extracted with TQT Plus methods. TQT Plus ECG extraction technique: Twelve-lead ECGs were extracted from continuous recordings (Holter recordings) prior to and serially after IMP administration at time points as shown in the Schedule of events. Subjects were supinely resting for at least 10 min prior to time points for ECG recordings. The 12-lead Holter and ECG equipment were supplied and supported by iCardiac Technologies, Inc. For all ECG parameters, baseline is defined as the average of the measured ECG intervals from the three pre-dose time points (45, 30, and 15 min pre-dose) on Day 1.

PRIMARY outcome

Timeframe: Pre-dose at following timepoints -2 h, -45 min, -30 min, -15 min. Then at following timepoints; 0, 5 min, 15 min, 30 min, 1 h, 2h, 3h, 4h, 5h, 6h, 8h, 12h and 24h post-dose.

Population: The QT/QTc Analysis Set includes all subjects in the Safety Analysis Set with measurements at baseline as well as on-treatment with at least one post-dose time point with a valid ΔQTcF (change from baseline QTcF) value.

At each nominal time point specified in the CSP, up to 10 ECG replicates were extracted with TQT Plus methods. TQT Plus ECG extraction technique: Twelve-lead ECGs were extracted from continuous recordings (Holter recordings) prior to and serially after IMP administration at time points as shown in the Schedule of events. Subjects were supinely resting for at least 10 min prior to time points for ECG recordings. The 12-lead Holter and ECG equipment were supplied and supported by iCardiac Technologies, Inc.

SECONDARY outcome

Timeframe: 5 minute post-dose time point

Predicted ΔΔQTcF interval at geometric mean Cmax for 5,10-MTHF, THF, and 5-Formyl-THF and geometric mean concentration of 5-Methyl-THF observed at 5 minutes post-dose The relationship between plasma concentrations of 5,10-MTHF, THF, 5-Methyl-THF, and 5-Formyl-THF, and change-from-baseline QTcF (ΔQTcF) was quantified using a linear mixed-effects modeling approach with separate analyses for each of the analytes (5,10-MTHF, THF 5-Methyl-THF, and 5-Formyl-THF) initially, with ΔQTcF as the dependent variable, plasma concentration of 5,10-MTHF (or THF, 5-Methyl-THF, or 5-Formyl-THF) as a continuous covariate (i.e., 0 for placebo), centered baseline QTcF as an additional covariate, treatment (active = 1 or placebo = 0) and time (i.e., time point) as categorical factors, and a random intercept and slope per subject. The degrees of freedom estimates were determined by the Kenward-Roger method.

Categorical T-wave morphology analysis and measurement of PR and QRS intervals were fully performed manually in three of the 10 ECG replicates at each time point. Final quality control and diagnostic interpretations were performed by the study cardiologist. When the results for each time point were compiled in the final data set, the comparison was made between ECG parameters from the three manually reviewed ECGs versus the 10 ECG replicates for quality control purposes. No treatment emergent T wave morphology changes were observed. In addition to the T-wave categorical analysis, the presence of abnormal U-waves was noted.
