An Investigational Study of Hydrocortisone

This study has been completed.
Sponsor:
Collaborator:
Simbec Research
Information provided by (Responsible Party):
Diurnal Limited
ClinicalTrials.gov Identifier:
NCT01960530
First received: October 6, 2013
Last updated: April 12, 2017
Last verified: April 2017
  Purpose

This study will investigate a new drug called Infacort®; a newly-developed immediate release formulation of a well-established drug called hydrocortisone. Hydrocortisone is used as a replacement treatment for people whose adrenal glands are not producing enough natural cortisol - a condition known as adrenal insufficiency. The study will assess how Infacort® acts once inside the body, by measuring cortisol and other hormone levels in the body, compared to already marketed hydrocortisone tablet and hydrocortisone intravenous (through the vein) injection.

The population who are eligible to take part in the study are healthy male volunteers, aged between 18 and 60 years of age.


Condition Intervention Phase
Adrenal Insufficiency Drug: Hydrocortisone granules Drug: Hydrocortisone Tablet Drug: i.v. Hydrocortisone Injection Other: Dexamethasone Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: None (Open Label)
Primary Purpose: Other
Official Title: An Open Label, Partially Randomised, Single Dose, Crossover Study to Evaluate the PK, Oral Bioavailability and Relationship to Metabolic Parameters of Hydrocortisone and Infacort® in Healthy Adult Male Volunteers.

Primary Outcome Measures:
  • Maximum Serum Concentration (Cmax) [ Time Frame: Hourly from 0 to 24 hours ]
    Derived PK for Serum Cortisol: Maximum serum concentration (Cmax)

  • AUC0-t [ Time Frame: Hourly from 0 to 24 hours ]
    Derived PK for Serum Cortisol: Area under the curve from 0-24 hours


Secondary Outcome Measures:
  • Adverse Events (AEs) [ Time Frame: Days 1-2 during each Study Period ]
    Number of subjects with adverse events throughout the study.

  • Concentrations of Cortisol Binding Protein [ Time Frame: Blood samples on Day 1 and/or Day 2 of each Study Period ]
    Cortisol protein binding under physiological conditions and after the administration of dexamethasone and hydrocortisone.

  • Insulin Sensitivity Under Physiological Conditions and After Administration of Dexamethasone and Infacort®, Hydrocortisone Tablets and i.v Hydrocortisone. [ Time Frame: Blood samples on Day 1 and/or Day 2 of each Study Period ]
    A standardised mixed meal elevates blood glucose and provides a reproducible stimulation of insulin release. Lower levels of insulin secretion, whilst maintaining normoglycaemia would indicate enhanced insulin sensitivity and glucose disposal; higher insulin levels will reflect insulin resistance.

  • PK and Metabolism of Cortisol [ Time Frame: Blood, urine & saliva samples on Day 1 and/or Day 2 of each Study Period ]
    Blood: Serum cortisol under physiological conditions and after administration of dexamethasone and Infacort® Granules, Hydrocortisone Tablets and i.v Hydrocortisone Injection.

Arms Assigned Interventions
No Intervention: Endogenous Cortisol
No Study medication will be given during this study period, however various blood, urine and saliva samples will be taken in order to measure normal levels of hormones and other chemicals at several time-points.
Dexamethasone
1mg Dexamethasone will be administered at 22:00 on Day 1 and at 06:00 and 12:00 on Day 2. Various blood, urine and saliva samples will be taken in order to measure normal levels of hormones and other chemicals at several time-points. Dexamethasone is considered a challenge agent and therefore a non-IMP
Other: Dexamethasone
Challenge agent
Other Name: Non-IMP
Experimental: Infacort®
20mg Infacort® will be administered on Day 2 at 07:00. Dexamethasone is a challenge agent and will be taken to suppress endogenous adrenocorticotropic Hormone (ACTH) and cortisol. 1mg Dexamethasone will be administered at 22:00 on Day 1 and 06:00 and 12:00 on Day 2. Various blood, urine and saliva samples will be taken in order to measure normal levels of hormones and other chemicals at several time-points.
Drug: Hydrocortisone granules
Multi-particulate granules
Other Name: Infacort
Active Comparator: Hydrocortisone Tablet
20mg Hydrocortisone Tablet will be administered on Day 2 at 07:00. Dexamethasone is a challenge agent and will be taken to suppress endogenous ACTH and Cortisol. 1mg Dexamethasone will be administered at 22:00 on Day 1 and 06:00 and 12:00 on Day 2. Various blood, urine and saliva samples will be taken in order to measure normal levels of hormones and other chemicals at several time-points.
Drug: Hydrocortisone Tablet
Standard hydrocortisone tablets
Other Name: Commerical supply
Active Comparator: i.v Hydrocortisone Injection
20mg i.v. Hydrocortisone Injection will be administered on Day 2 at 07:00. Dexamethasone is a challenge agent and will be taken to suppress endogenous ACTH and Cortisol. 1mg Dexamethasone will be administered at 22:00 on Day 1 and 06:00 and 12:00 on Day 2. Various blood, urine and saliva samples will be taken in order to measure normal levels of hormones and other chemicals at several time-points.
Drug: i.v. Hydrocortisone Injection
Standard hydrocortisone solution for intravenous injection
Other Name: Commerical supply

Detailed Description:
The study will evaluate the normal physiology, PK and metabolism of cortisol, investigate the PK and bioavailability of cortisol from the test Infacort® Granules (hydrocortisone) and the reference hydrocortisone tablets and i.v injection in healthy adult male volunteers and explore the role of cortisol in the regulation of metabolic pathways.
