Pregnyl (Human Chorionic Gonadotropin) - Summary

 
 



PREGNYL SUMMARY

Human chorionic gonadotropin (HCG), a polypeptide hormone produced by the human placenta, is composed of an alpha and a beta sub-unit. The alpha sub-unit is essentially identical to the alpha sub-units of the human pituitary gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone (FSH), as well as to the alpha sub-unit of human thyroid-stimulating hormone (TSH). The beta sub-units of these hormones differ in amino acid sequence. PREGNYL® (chorionic gonadotropin for injection, USP) is a highly purified pyrogen-free preparation obtained from the urine of pregnant females. It is standardized by a biological assay procedure. It is available for intramuscular injection in multiple dose vials containing 10,000 USP Units of sterile dried powder with 5 mg monobasic sodium phosphate and 4.4 mg dibasic sodium phosphate. If required, pH is adjusted with sodium hydroxide and/or phosphoric acid. Each package also contains a 10 mL vial of solvent containing: water for injection with 0.56% sodium chloride and 0.9% BENZYL ALCOHOL, WHICH IS NOT FOR USE IN NEWBORNS. If required, pH is adjusted with sodium hydroxide and/or hydrochloric acid.

PREGNYL (CHORIOGONADOTROPIN ALFA) is indicated for the following:

HCG HAS NOT BEEN DEMONSTRATED TO BE EFFECTIVE ADJUNCTIVE THERAPY IN THE TREATMENT OF OBESITY. THERE IS NO SUBSTANTIAL EVIDENCE THAT IT INCREASES WEIGHT LOSS BEYOND THAT RESULTING FROM CALORIC RESTRICTION, THAT IT CAUSES A MORE ATTRACTIVE OR “NORMAL” DISTRIBUTION OF FAT, OR THAT IT DECREASES THE HUNGER AND DISCOMFORT ASSOCIATED WITH CALORIE-RESTRICTED DIETS.

  1. Prepubertal cryptorchidism not due to anatomical obstruction. In general, HCG is thought to induce testicular descent in situations when descent would have occurred at puberty. HCG thus may help predict whether or not orchiopexy will be needed in the future. Although, in some cases, descent following HCG administration is permanent, in most cases, the response is temporary. Therapy is usually instituted in children between the ages of 4 and 9.
  2. Selected cases of hypogonadotropic hypogonadism (hypogonadism secondary to a pituitary deficiency) in males.
  3. Induction of ovulation and pregnancy in the anovulatory, infertile woman in whom the cause of anovulation is secondary and not due to primary ovarian failure, and who has been appropriately pretreated with human menotropins.

PURPOSE: To compare the efficacy of two regimens of low dose human chorionic gonadotropin (hCG) on follicular response and oocyte maturation in women with polycystic ovarian syndrome (PCOS)... CONCLUSIONS: A combination of FSH and low dose hCG improved oocyte maturity and preserved outcomes with improved safety and lowered cost.

Clinical Trials Related to Pregnyl (Chorionic Gonadotropin)

Study of Pregnyl as Adjunct Therapy for High-Risk or Refractory Acute GVHD [Not yet recruiting]
The purpose of this study is to determine the maximum tolerated dose (MTD) of Pregnyl when given in combination with standard immunosuppressive therapy in pediatric and adult patients with high-risk (Arm 1) or refractory (Arm 2) aGVHD.

A Randomised Trial Using Highly Purified Human Chorionic Gonadotropin (HP-hCG) and Recombinant Human Chorionic Gonadotropin (rhCG) in Women Undergoing Controlled Ovarian Stimulation [Not yet recruiting]
