A Food Effect Study of 60mg ER Torsemide

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT03215875

Brief Summary:
This study will evaluate the effects of a high-fat meal (food effect) on the bioavailability and pharmacokinetics of 60mg ER Torsemide tablet after single dose oral administration in healthy volunteers. The study will be conducted as a two-sequence to period crossover study to compare 60mg ER Torsemide ER bioavailability under fed and fasting conditions. 60mg ER torsemide is a new strength and dosage form.

Condition or disease Intervention/treatment Phase
Food-drug Interaction Drug: Fed- 60mg ER Torsemide Drug: Fasting- 60mg ER Torsemide Phase 1

Detailed Description:
Immediate Release (IR) Torsemide is a highly effective natriuretic drug but its short duration of action is a major drawback, which allows significant post-dose sodium retention, and as consequence, limits salt loss in patients with heart failure unless dietary salt intake is severely restricted. Extended Release (ER) torsemide is being developed to address this drawback by prolonging the duration of action to increase sodium excretion even in patients who consume high salt diet. Since 60mg ER torsemide is a new strength and dosage form, this study will test 60mg ER torsemide for a food effect in healthy volunteers who are either fasting or consuming a high-fat meal (fed). The primary endpoint of the study is full pharmacokinetics measurements after a single dose of 60mg ER torsemide. The secondary endpoints are 24h sodium excretion and total urinary excretion.

Drug Information available for: Torsemide

Arm Intervention/treatment
Experimental: Fed- 60mg ER Torsemide
Adult healthy subjects will be given standardized high-fat, high-calorie meal prior to dosing
Drug: Fed- 60mg ER Torsemide
60mg ER Torsemide will be given after high fat, high-calorie meal
Other Name: High fat/high-calorie fed conditions

Experimental: Fasting- 60mg ER Torsemide
Adult healthy subjects will fast overnight (at least 10h) prior to dosing
Drug: Fasting- 60mg ER Torsemide
60mg ER Torsemide will be given after overnight fasting
Other Name: Fasting conditions

Primary Outcome Measures :
  1. Peak torsemide plasma concentration [ Time Frame: 36 hours ]
    Peak plasma concentration (Cmax) (ng/ml) in fed and fasting conditions

  2. Total torsemide plasma concentration [ Time Frame: 36 hours ]
    Area under the plasma concentration versus time curve (AUC) (hr/ng/ml) in fed and fasting conditions

Secondary Outcome Measures :
  1. Urinary torsemide excretion [ Time Frame: 36 hours ]
    torsemide will be measured in urine over 36 hours post-dose (microgram/min)

  2. Urinary sodium excretion [ Time Frame: 36 hours ]
    36-hour sodium excretion will be measure (mmol/min)
