Um estudo investigativo de hidrocortisona

10 de setembro de 2026 atualizado por: Neurocrine UK Limited

Um Estudo Aberto, Parcialmente Randomizado, Dose Única, Crossover para Avaliar a PK, Biodisponibilidade Oral e Relação com Parâmetros Metabólicos de Hidrocortisona e Infacort® em Voluntários Adultos Saudáveis ​​do Sexo Masculino.

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.

Visão geral do estudo

Descrição detalhada

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.

Descrição

Inclusion Criteria:

  • A clinically significant history or family history of psychiatric disorders/illnesses.
  • A clinically significant history of drug or alcohol abuse.
  • Inability to communicate well with the Investigator (i.e., language problem, poor mental development or impaired cerebral function).
  • Participation in a New Chemical Entity clinical study within the previous 4 months or a marketed drug clinical study within the previous 3 months. (N.B. The washout period between trials is defined as the period of time elapsed between the last dose of the previous study and the first dose of the next study)
  • Subjects who have consumed more than 2 units of alcohol per day within seven (7) days prior to Day 1 of Study Period 1or have consumed any alcohol within the 48 hour period prior to Day 1 of Study Period 1.
  • Donation of 450ml or more of blood within the previous 3 months.
  • Subjects who smoke (or ex-smokers who have smoked within 6 months prior to Day 1 of Study Period 1).
  • Subjects who work shifts (i.e. regularly alternate between days, afternoons and nights).

Armas e Intervenções

Grupo de Participantes / Braço
Intervenção / Tratamento
Sem intervenção: 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.

Outro: 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

Challenge agent

Outros nomes:
  • Não 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.

Cortisol protein binding under physiological conditions and after the administration of dexamethasone and hydrocortisone.

Blood samples on Day 1 and/or Day 2 of each Study Period
Insulin Sensitivity Under Physiological Conditions and After Administration of Dexamethasone and Infacort®, Hydrocortisone Tablets and i.v Hydrocortisone.
Prazo: 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.

Blood samples on Day 1 and/or Day 2 of each Study Period

Prazo: 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.
