Study Description

Brief Summary

Female sex is an independent risk factor for the potentially fatal drug-induced arrhythmia (irregular heartbeat) known as torsades de pointes (TdP), which is associated with prolongation of the corrected QT (QTc) interval on the electrocardiogram (ECG). Mechanisms for this increased risk in women are not well-understood. QTc interval duration has been shown to fluctuate throughout the phases of the menstrual cycle. Evidence indicates that the QTc interval response to drugs that may cause TdP is greater during the menses and ovulation phases of the menstrual cycle, during which serum progesterone concentrations are lowest, and lesser during the luteal phase, during which serum progesterone concentrations are highest. Additional evidence from our laboratory suggests that progesterone may be protective against TdP. Specific Aim 1: Establish the influence of oral progesterone administration as a preventive method by which to diminish the degree of drug-induced QT interval prolongation in women. Working hypothesis: Oral progesterone administration effectively attenuates enhanced drug-induced QT interval response in women. To test this hypothesis, progesterone or placebo will be administered in a crossover fashion to women during the menses phase of the menstrual cycle. QTc interval response to low-dose ibutilide, a drug known to lengthen the QT interval, will be assessed. The primary endpoint will be individually-corrected QT interval (QTcI) response to ibutilide, in the presence and absence of progesterone, which will be assessed by: 1) Effect on maximum change in QTcI, and 2) Area under the QTcI interval-time curves (AUEC). At the conclusion of this study, we will have established that oral progesterone administration is a safe and effective method of attenuating drug-induced QT interval prolongation.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Progesterone

Subjects will receive treatment with oral progesterone 400 mg once daily (two x 200 mg capsules) every evening for 7 days

Drug: Progesterone
Subjects will receive oral progesterone 400 mg (two x 200 mg capsules) once daily every evening for 7 days

Drug: Ibutilide
Ibutilide 0.003 mg/kg administered to all subjects to moderately lengthen the QT interval

Placebo Comparator: Placebo

Subjects will receive oral placebo, two capsules once daily every evening for 7 days

Drug: Placebo
Subjects will receive oral placebo two capsules once daily every evening for 7 days

Drug: Ibutilide
Ibutilide 0.003 mg/kg administered to all subjects to moderately lengthen the QT interval

Outcome Measures

Primary Outcome Measures

  1. Baseline (Pre-Ibutilide) QTcI Intervals [After 7 days of progesterone or placebo, prior to receiving IV ibutilide]

  2. Maximum Individual-corrected QT Interval (QTcI) [0, 15 & 30 minutes, and 1, 2, 4, 6, 8, and 12 hours post-ibutilide administration]

    QT intervals will be corrected as follows: Prior to randomization, subjects will come to the Indiana Clinical Research Center for a 12-hour stay, during which three ECGs, one minute apart, will be obtained at the following times: 0, 15 & 30 minutes, and 1, 2, 4, 6, 8, and 12 hours. Subjects will be discharged, and then return then next morning for the 24 hour ECG. QT and RR intervals will be used to determine each subject's individual rate-corrected QT interval (QTcI) using the parabolic model QT = β•RRα, where RR is the interval between adjacent QRS complexes, and α and β are subject-specific correction factors.

  3. Maximum % Change From Baseline in QTcI Intervals Following Ibutilide Administration [After 7 days of progesterone or placebo]

  4. Area Under the QTcI - Time Curve (AUEC) [From beginning of 10-minute ibutilide infusion to 1 hour following ibutilide infusion]

Secondary Outcome Measures

  1. Incidence of Progesterone-associated Adverse Effects Compared to Placebo [During 7 days of treatment with oral progesterone or placebo]

Other Outcome Measures

  1. Adverse Effects Associated With Ibutilide in the Progesterone and Placebo Phases [Within 8 hours following ibutilide administration]

  2. Maximum (Peak) Serum Ibutilide Concentrations During Progesterone and Placebo Phases [Within 1 hour following ibutilide administration (0, 15 & 30 minutes and 1 hours.)]

  3. Serum Estradiol Concentrations During the Progesterone and Placebo Phases [Following 7 days of progesterone or placebo]

  4. Serum Progesterone Concentrations During Progesterone and Placebo Phases [After 7 days of progesterone or placebo]

  5. Ratio of Serum Progesterone:Estradiol Concentrations During the Progesterone and Placebo Phases [After 7 days of progesterone or placebo]
