An Open Label, Canadian Phase IIIb Study With Ovidrel in Ovulation Induction (OI) and Assisted Reproductive Technique (ART)

2014-08-27 03:12:36 | BioPortfolio

Summary

With the development of the recombinant gonadotrophins, the use of human source proteins for the production of hormones has become unnecessary. These proteins, which are found in urinary preparations, have been thought to cause the local, post-injection adverse events (AEs) in some subjects.

There has been a demand by physicians for an alternative to urinary products for treatment. Due to allergies to urinary products, or other personal reasons, subjects were not able or willing to be treated with proteins of human origin. This study allowed subjects to be treated with the recombinant human chorionic gonadotropin (r hCG) (free of urinary proteins), which otherwise would not be possible. The study sponsor used this opportunity to collect additional safety data on the new recombinant product, (Ovidrel, r-hCG).

Description

Approximately one in ten couples of reproductive age experiences infertility. Infertility may be caused by problems in men, in women or in both. A number of techniques can be used depending on the duration and type of infertility problems. The treatment of ovulation induction (OI) uses the help of exogenous gonadotrophins such as follicle stimulating hormone (FSH), luteinizing hormone (LH) and hCG in order to stimulate follicles and release oocytes for fertilization in the fallopian tubes.

Assisted reproductive technologies (ARTs), including in-vitro fertilization (IVF) and intra- cytoplasmic sperm injection (ICSI), increases the chances of success to obtain more than one embryo. In order to obtain more than one embryo, it is necessary to stimulate the growth and maturation of several follicles. Such a multiple follicular development is obtained by daily administration of a follicle stimulating hormone (r-hFSH, Gonal-F). When these follicles have reached a large enough size, the role of hCG is to achieve final oocyte maturation and initiation of follicular luteinization.

Serono International S.A. has developed a pharmaceutical preparation of human chorionic gonadotrophin (hCG) for clinical use through the application of recombinant DNA technology. The resulting product is choriogonadotrophin alpha, a pure recombinant human chorionic gonadotrophin (r-hCG). The corresponding drug product is marketed under the tradename Ovidrel. Ovidrel (choriogonadotrophin alpha for injection) has been approved in the United States, in the European Union and Australia.

OBJECTIVES The objective of this study was to collect safety information in order to confirm the already known profile of r- hCG (Ovidrel).

Medical and Biotech [MESH] Definitions

Techniques for the artifical induction of ovulation, the rupture of the follicle and release of the ovum.

Blocking the process leading to OVULATION. Various factors are known to inhibit ovulation, such as neuroendocrine, psychological, and pharmacological agents.

The period in the MENSTRUAL CYCLE that is optimal for FERTILIZATION of the OVUM and yielding PREGNANCY. The duration of fertile period depends on the life span of male GAMETES within the female reproductive tract and the time of OVULATION. It usually begins a few days before ovulation and ends on the day of ovulation.

Predicting the time of OVULATION can be achieved by measuring the preovulatory elevation of ESTRADIOL; LUTEINIZING HORMONE or other hormones in BLOOD or URINE. Accuracy of ovulation prediction depends on the completeness of the hormone profiles, and the ability to determine the preovulatory LH peak.

An inactive metabolite of PROGESTERONE by reduction at C5, C3, and C20 position. Pregnanediol has two hydroxyl groups, at 3-alpha and 20-alpha. It is detectable in URINE after OVULATION and is found in great quantities in the pregnancy urine.
