About

In-vitro fertilization (IVF) of human oocytes followed by the replacement of embryo in the uterine cavity has become a well established treatment for female infertility attributable to damaged fallopian tubes, endometriosis or unexplained causes where alternative forms of therapy have failed. The most commonly used protocols of follicular stimulation now employs follicle stimulating hormone (FSH) and long-acting agonists of gonadotropin releasing hormone (GnRH) to prevent the occurrence of a mid-cycle luteinizing hormone (LH) surge and to ensure the induction of well-synchronized larger cohort of ovarian follicles.

The results of a number of studies have demonstrated that in the majority of clinical situations, FSH administration alone is sufficient to achieve successful follicular development. A study had shown that in subjects receiving recombinant human-follicle stimulating hormone (r-hFSH) and recombinant human-luteinizing hormone (r-hLH), pregnancy rates were similar in the younger and older age groups, however, in women receiving r-hFSH alone, there was a significant decline in pregnancy rates for women 35 and older. This particular study also went on to show that the subgroup of women 35 and older, may benefit from supplementary r-hLH. A number of studies have been conducted to assess the safety and efficacy of r-hLH administered concomitantly with r-hFSH in the presence of developing follicles to reduce the rate of growth of intermediate and small follicles while allowing the dominant follicle to continue to progress.

This was a Phase III, open-label, multicentre study to evaluate safety and efficacy of addition of Recombinant Human-Luteinizing Hormone (Luveris) to a standard assisted reproductive technologies (ART) protocol.

Full description

Luteinizing hormone is a heterodimeric glycoprotein composed of a non-covalent association of an α and a β subunit. Prior to the generation of human-LH (hLH) through recombinant technology, hLH had only been available for therapeutic use as human menopausal gonadotropins (hMG), a co-extracted, purified preparation of hLH and hFSH from urine of post menopausal women. Recombinant Human-Luteinizing Hormone (Luveris) has been found to be well tolerated in human pharmacokinetic and pharmacodynamic studies at doses of up to 40,000 IU in healthy female volunteers without any Serious Adverse Event (SAE) experience being reported.

OBJECTIVES

To evaluate safety and efficacy of addition of Recombinant Human-Luteinizing Hormone (Luveris) to a standard ART procedure.

In this study, subjects were first treated with a GnRH agonist to induce pituitary desensitization according to centre's standard practice followed by administration of r-hFSH. All subjects were then treated with Recombinant Human -Luteinizing Hormone (Luveris)150 IU per day subcutaneous (s.c.) from Day 6 of stimulation of their ART treatment cycle, continuing at the same dose until injection of hCG upto and including day of last FSH dose.

Inclusion criteria

Female subjects who underwent ovarian stimulation for ART (IVF/ICSI) using r-hFSH.
Subjects who in the opinion of the treating investigator met any of the following criteria to require r-LH supplementation during the ovarian stimulation:
- were selected for a GnRH agonist protocol to induce pituitary desensitization
- previous poor ovarian response to r-hFSH alone
- aged 35 to 40 years
- elevated baseline hormone parameters that were predictive of poor ovarian response
