Phase III Randomized, Double-Blind, Placebo-Controlled Study of Dehydroepiandrosterone Replacement for Primary Adrenal Insufficiency

2014-07-23 21:56:51 | BioPortfolio

Summary

OBJECTIVES:

I. Determine the efficacy of dehydroepiandrosterone (DHEA), an androgen replacement hormone, for patients with primary adrenal insufficiency (Addison's disease).

Description

PROTOCOL OUTLINE: This is a randomized, double-blind study. Patients are stratified by age.

Patients are randomly assigned to androgen replacement therapy with daily dehydroepiandrosterone (DHEA) or placebo for 6 months. All patients may receive 6 additional months of DHEA following randomized therapy.

Women on hormonal replacement therapy may receive concurrent conjugated estrogens or oral medroxyprogesterone.

Medical and Biotech [MESH] Definitions

A major C19 steroid produced by the ADRENAL CORTEX. It is also produced in small quantities in the TESTIS and the OVARY. Dehydroepiandrosterone (DHEA) can be converted to TESTOSTERONE; ANDROSTENEDIONE; ESTRADIOL; and ESTRONE. Most of DHEA is sulfated (DEHYDROEPIANDROSTERONE SULFATE) before secretion.

Immune-mediated inflammation of the PITUITARY GLAND often associated with other autoimmune diseases (e.g., HASHIMOTO DISEASE; GRAVES DISEASE; and ADDISON DISEASE).

21-Hydroxypregn-4-ene-3,20-dione. Desoxycorticosterone acetate (DOCA) is used as replacement therapy in ADDISON DISEASE.

An adrenal disease characterized by the progressive destruction of the ADRENAL CORTEX, resulting in insufficient production of ALDOSTERONE and HYDROCORTISONE. Clinical symptoms include ANOREXIA; NAUSEA; WEIGHT LOSS; MUSCLE WEAKNESS; and HYPERPIGMENTATION of the SKIN due to increase in circulating levels of ACTH precursor hormone which stimulates MELANOCYTES.

Autoimmune diseases affecting multiple endocrine organs. Type I is characterized by childhood onset and chronic mucocutaneous candidiasis (CANDIDIASIS, CHRONIC MUCOCUTANEOUS), while type II exhibits any combination of adrenal insufficiency (ADDISON'S DISEASE), lymphocytic thyroiditis (THYROIDITIS, AUTOIMMUNE;), HYPOPARATHYROIDISM; and gonadal failure. In both types organ-specific ANTIBODIES against a variety of ENDOCRINE GLANDS have been detected. The type II syndrome differs from type I in that it is associated with HLA-A1 and B8 haplotypes, onset is usually in adulthood, and candidiasis is not present.
