A Prospective Study to Evaluate the Addition of Subcutaneous Recombinant Human-Luteinizing Hormone With Recombinant Human-Follicle Stimulating Hormone on Follicular Development in Women Undergoing Ovarian Stimulation for Assisted Reproductive Technologies
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.

- Mean Number of Metaphase II Oocytes Per Participant Who Underwent Ovum Pick up for Intra-cytoplasmic Sperm Injection (ICSI) [ Time Frame: On the day of ovum pick up (Day 1 or 2 after human chorionic gonadotropin [hCG] administration). ] [ Designated as safety issue: No ]Mean number of metaphase II oocytes was calculated for each participant undergoing ovum pick up for ICSI. ICSI is an in-vitro fertilization procedure in which a single sperm is injected directly into an egg under a microscope. Metaphase II stage of the oocyte was classified as the time at which the first polar body was observed microscopically. Metaphase II oocytes are a sub-group of the total number of oocytes.
- Mean Number of Mature Oocytes Per Participant Who Underwent Ovum Pick up for In Vitro Fertilization (IVF) [ Time Frame: On the day of ovum pick up (Day 1 or 2 after hCG administration). ] [ Designated as safety issue: No ]Mean number of oocytes undergoing ovum pick up for IVF were calculated for each participant. IVF is a process by which egg cells are fertilized by sperm outside the body, in-vitro.
- Mean Number of Oocytes Retrieved Per Number of Follicles Aspirated on the Day of Ovum Pick up [ Time Frame: On day of ovum pick up (Day 1 or 2 after hCG administration) ] [ Designated as safety issue: No ]Mean number of oocytes retrieved per number of follicles aspirated on the day of ovum pick up was calculated. Oocyte retrieval is a technique used in in vitro fertilization in order to remove oocytes from the ovary of the female, enabling fertilization outside the body.
- Number of Participants With Confirmed Pregnancies: Biochemical Pregnancies and Clinical Pregnancies [ Time Frame: Post-hCG days 15-20 and post-hCG days 35-42. ] [ Designated as safety issue: No ]Biochemical pregnancy: A positive pregnancy test defined as hCG level >10 IU/L in a sample taken at least 14 days after Day 3 embryo transfer or 12 days after Day 5/6 embryo transfer with no further ultrasound confirmation of the existence of a gestational sac in the uterus. Clinical pregnancy: Existence of at least one ultrasonography confirmed gestational sac in the uterus, with or without heartbeat.
- Number of Participants With Multiple Pregnancies [ Time Frame: Post-hCG Day 35-42. ] [ Designated as safety issue: No ]Multiple pregnancy is a pregnancy where more than one fetus develops simultaneously in the womb. There are two types of twinning—identical and fraternal. Identical twins represent the splitting of a single fertilized zygote (union of two gametes or male/female sex cells that produce a developing fetus) into two separate individuals.
- Number of Live Births [ Time Frame: Post-hCG days 15-20 to pregnancy follow up. ] [ Designated as safety issue: No ]A live birth occurs when a fetus, whatever its gestational age, exits the maternal body and subsequently shows any sign of life, such as voluntary movement, heartbeat, or pulsation of the umbilical cord, for however brief a time and regardless of whether the umbilical cord or placenta are intact.
- Pregnancy Loss Per Clinical Pregnancy [ Time Frame: Post-hCG days 35-42. ] [ Designated as safety issue: No ]Preclinical miscarriage: Spontaneous cessation of a biochemical pregnancy. Early spontaneous abortion: Any spontaneous abortion occurring after confirmation of clinical pregnancy and before completion of 12 weeks of gestation. Late spontaneous abortion: any spontaneous abortion occurring between completion of 12 weeks of gestation and prior to a viable stage. Pregnancy loss per clinical pregnancy was measured as a percentage.
- Number of Participants With Treatment Emergent Adverse Events (TEAEs), Serious Adverse Events (SAEs) and Adverse Events (AEs) Leading to Study Drug Discontinuation. [ Time Frame: From stimulation Day 1 (S1) to post-hCG days 35-42 (safety visit). ] [ Designated as safety issue: Yes ]AEs: Any new untoward medical occurrences/worsening of pre-existing medical condition, whether or not related to study drug. TEAEs: AEs that occur during treatment with the study drug. It also included incidences of mild, moderate and severe ovarian hyperstimulation syndrome (OHSS). SAE: any AE that resulted in death; was life threatening; resulted in persistent/significant disability/incapacity; resulted in/prolonged an existing in-patient hospitalization; was a congenital anomaly/birth defect; or was an overdose. Participants who discontinued from the study due to AE were also recorded.

Drug: Recombinant Human-Luteinizing Hormone (Luveris)
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.
- 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.
