Brief Summary:
The purpose of this study is to evaluating ECG effects, safety, tolerability and pharmacokinetics of single ascending dose of Modufolin® in healthy male volunteers

Condition or disease Intervention/treatment Phase
Phase I Study in Healthy Volunteers to Evaluate ECG Effect Drug: Modufolin (arfolitixorin) Phase 1

Detailed Description:
An adaptive randomised, double-blind, single-centre, placebo-controlled Phase I study evaluating ECG effects, safety, tolerability and PK of single ascending doses of Modufolin® for Injection, 100 mg in healthy male volunteers. Thirty-three (33) eligible and consenting subjects will be included in 3 cohorts, 11 subjects in each cohort. Within each cohort, subjects will be randomised to receive either placebo (3 subjects) or Modufolin® for Injection, 100 mg (8 subjects). There will be 3 pre-defined ascending dose-levels. Additional dose levels may be considered if recommended by the internal Safety Review cCommittee. There will be an interval between each dose level to allow time for safety data to be analyzed and evaluated by the iSRC. The iSRC will have the choice to decide to escalate the dose as planned, reduce or increase the dose escalation step, repeat the dose, reduce the dose or terminate the study. The total study duration for the subjects will be approximately 5 weeks and there will be in total 3 visits to the clinic. Subjects will be screened for eligibility according to study-specific inclusion/exclusion criteria within 4 weeks prior to start of stud treatment (Visit 1; Screening visit). The subjects will be confined to the research clinic from the evening before dosing (Day -1) until 24 hrs post dose (Days 1 and 2). The subjects should be fasting overnight (8 hrs) before IMP/placebo administration until 4 hrs post-dose. A Follow-up Visit will be performed 5 to 10 days after dose administration of for each cohort.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 33 participants
Allocation: Randomized
Intervention Model: Single Group Assignment
Intervention Model Description: An adaptive, randomized, double-blind, single-center, placebo-controlled
Masking: Triple (Participant, Investigator, Outcomes Assessor)
Masking Description: IMP (Modufolin® for Injection, 100 mg) and Placebo are not identical in appearance and all efforts will be made at the clinic in order to maintain the blind. Both the IMP and the placebo will be masked in such a way that study subjects and study staff will remain blinded during the study. An un-blinded study nurse will prepare the IMP/placebo for injection and will administer the IMP/placebo to the study subject. The un-blinded study nurse performing the dose administration will not be involved in any study-specific assessments or evaluations.

Primary Outcome Measures :
  1. Change-from-baseline QTcF (ΔQTcF) [ Time Frame: 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. ]

    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.



Secondary Outcome Measures :

    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.

  2. Change-from-baseline Heart Rate (ΔHR) [ Time Frame: 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. ]
    The analysis was based on the change-from-baseline post-dosing values. The same (by-time point analysis) model was used as described for QTcF. 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 predose) on Day 1.

  3. Change-from-baseline PR (ΔPR) [ Time Frame: 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. ]
    The analysis was based on the change-from-baseline post-dosing values. The same (by-time point analysis) model was used as described for QTcF. 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 predose) on Day 1.

  4. Change-from-baseline QRS (ΔQRS) [ Time Frame: 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. ]

  6. Categorical Outliers for HR, PR Interval, QRS Interval [ Time Frame: 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. ]
    Categorical Analysis of outliers for HR, PR, and QRS intervals

  7. Categorical Analysis for T Wave Morphology [ Time Frame: 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. ]
    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.
