GONAL-f CONSORT (Consistency in r-hFSH Starting Doses for Individualised Treatment)

2014-08-27 03:14:44 | BioPortfolio


This non-interventional study (NIS) is planned to examine the consistency of the dose recommended by the doctor for the first stimulation day with the dose recommended by the CONSORT calculator.


Since the introduction of the first recombinant human follicle stimulating hormone (FSH) preparation Gonal-f in the year 1996, a pure drug is available as raw material, which is independent of human urine due to biotechnological methods and consequently can be produced free of contaminating proteins. In accordance with the recommendations of European Medicines Agency (EMEA) in February 1999, on the basis of data from clinical studies, Gonal-f should be regarded as the more effective preparation in comparison to urinary FSH. Serono has developed a dose calculator, the CONSORT calculator, after analyzing the data from clinical studies for Gonal-f. This non-interventional study is planned to examine the consistency of the dose recommended by the doctor for the first stimulation day with the dose recommended by the CONSORT calculator. All subjects, who undergo stimulation with Gonal-f in preparation for a technology of the assisted conception in accordance with the permitted indication, will be included in this non-interventional study.


Primary Objective:

- To examine, how far the dose recommended by the doctor for the first stimulation day varies from the dose recommended by the CONSORT calculator

Medical and Biotech [MESH] Definitions

The beta subunit of follicle stimulating hormone. It is a 15-kDa glycopolypeptide. Full biological activity of FSH requires the non-covalently bound heterodimers of an alpha and a beta subunit. Mutation of the FSHB gene causes delayed puberty, or infertility.

A major gonadotropin secreted by the human adenohypophysis (PITUITARY GLAND, ANTERIOR). Follicle-stimulating hormone stimulates GAMETOGENESIS and the supporting cells such as the ovarian GRANULOSA CELLS, the testicular SERTOLI CELLS, and the LEYDIG CELLS. FSH consists of two noncovalently linked subunits, alpha and beta. The alpha subunit is common in the three human pituitary glycoprotein hormones (TSH, LH, and FSH), but the beta subunit is unique and confers its biological specificity.

Receptors with a 6-kDa protein on the surfaces of cells that secrete LUTEINIZING HORMONE or FOLLICLE STIMULATING HORMONE, usually in the adenohypophysis. LUTEINIZING HORMONE-RELEASING HORMONE binds to these receptors, is endocytosed with the receptor and, in the cell, triggers the release of LUTEINIZING HORMONE or FOLLICLE STIMULATING HORMONE by the cell. These receptors are also found in rat gonads. INHIBINS prevent the binding of GnRH to its receptors.

Extracts of urine from menopausal women that contain high concentrations of pituitary gonadotropins, FOLLICLE STIMULATING HORMONE and LUTEINIZING HORMONE. Menotropins are used to treat infertility. The FSH:LH ratio and degree of purity vary in different preparations.

A protein extract of human menopausal urine in which LUTEINIZING HORMONE has been partially or completely removed. Urofollitropin represents FOLLICLE STIMULATING HORMONE from the urine.
