Gonadotropin-Releasing Hormone (GnRH) Analogs, Hormones and Antagonists
NOTE: This policy addresses the singular use of GnRH analogue ALONE. This policy does not address the combined use of luteinizing hormone-releasing hormone (LHRH) agonists AND anti-androgens.
Gonadotropin-Releasing Hormone (GnRH) analogs, hormones and antagonists are addressed individually by brand names and may be considered medically necessary for the indications listed beneath each drug and:
Off-label use of FDA approved drugs is considered not medically necessary:
Plenaxis™ (Abarelix) may be considered medically necessary for the palliative treatment of men with advanced symptomatic prostate cancer, in whom LHRH agonist therapy is not appropriate and who refuse surgical castration, and have one or more of the following:
Cetrotide (Antagon) [ganirelix acetate] may be considered medically necessary for infertility treatment to inhibit luteinizing hormone (LH) surges. (Check member benefit contracts for coverage).
Eligard (Lupron, Viadur) may be considered medically necessary for the following:
A. Oncology Uses:
B. Gynecology Uses:
NOTE: The following recommendations from ACOG are based on Level A scientific evidence: When relief of pain from treatment with a GnRH agonist supports continued therapy, the addition of add-back therapy reduces or eliminates GnRH-induced bone mineral loss without reducing the efficacy of pain relief.
NOTE: The following recommendations are from the Lupron Drug Insert: If the symptoms of endometriosis recur after a course of therapy, retreatment with a six-month course of LUPRON DEPOT and norethindrone acetate 5 mg daily may be considered. Retreatment beyond this one six-month course cannot be recommended. It is recommended that bone density be assessed before retreatment begins to ensure that values are within normal limits. Retreatment with LUPRON DEPOT alone is not recommended
C. Endocrine Uses:
Lupron is contraindicated in women who are or may become pregnant while receiving the drug. Lupron may cause fetal harm when administered to a pregnant woman.
Lutrepulse (Factrel): may be considered medically necessary for the following:
B. Endometriosis: For pain relief and reduction of lesions for duration of therapy (management of chronic pelvic pain).
C. Breast Cancer: Palliative treatment of breast cancer in pre- or post-menopausal women.
Zoladex: may be considered medically necessary for the following indications:
A. Oncology Uses:
B. Gynecology Uses:
Supprelin (Vantas, Histrelin): may be considered medically necessary for the following indications:
A. Prostate Cancer Patients:
B. Endocrine Uses: Central precocious puberty (CPP), gonadotropin-dependent, male or female.
Synarel: may be considered medically necessary for the following indications:
A. Gynecology Uses:
B. Endocrine Uses: Central precocious puberty (CPP), gonadotropin-dependent, male or female.
Trelstar Depot: may be considered medically necessary for the following indications:
Administration of GnRH analogs, hormones and antagonists are considered not medically necessary for the following:
A. Gynecology Uses:
B. Prostate Cancer Patients:
C. Miscellaneous Clinical Conditions:
NOTE: Check contract or legislative provisions which may mandate benefits.
Acting on the pituitary gland in the brain, GnRH suppresses function of the ovaries and testes, blocking the production of testosterone in males and estrogen in females. Repeated monthly injections of these drugs cause gonadal hormone dependent tissues or organs to reduce or cease activity, such as the normal prostrate gland that is dependent on testosterone for growth and function. This effect is reversible on discontinuation of the drug therapy.
Although GnRH products may differ in specific labeled indications and dosing requirements, clinical evidence does not support differential effectiveness of one product over the other for FDA approved clinical indications.
Plenaxis (Abarelix) has been approved for marketing under a voluntary risk management program (RMP) to patients with advanced prostate cancer. RMP is a strict Prescribing Program, part of an expedited drug approval pathway, to reserve specific pharmaceuticals to patients where the medical benefits outweigh the risks. RMP requirements generally include all of the following:
Cetrotide® (cetrorelix acetate [ganirelix acetate] for injection) a synthetic decapeptite analog of gonadotropin-releasing hormone (GnRH), is a GnRH antagonist. It is used as a component of infertility regimens (recombinant FSH or human menopausal gonadotropin (hMG), centrorelix, and human chorionic gonadotropin (hCG) to inhibit premature luteinizing hormone (LH) surges in women undergoing controlled ovarian stimulation (COS).
Leuprolide acetate (Eligard, Lupron, Viadur) is a synthetic analog of naturally occurring gonadotropin releasing hormone (GnRH or LH-RH). The analog possesses greater potency than the natural hormone. Because of its inhibitory effect on gonadotropin secretion and androgen or estrogen synthesis, leuprolide inhibits growth of hormone-dependent tumors. Leuprolide has reduced the size of the prostate gland and has inhibited prostatic tumor growth. There is also evidence to suggest that leuprolide inhibits the growth of estrogen-dependent mammary tumors mainly by inhibiting ovarian function and estrogen synthesis.
Lutrepulse (Factrel) is another form of gonadotropin-releasing hormone (GnRH) that is naturally released from the hypothalamus gland. GnRH causes the pituitary gland to release other hormones LH and follicle-stimulating hormone [FSH]). LH and FSH control development in children and fertility in adults.
Supprelin (Vantas) is a GnRH antagonist that lowers the male hormone testosterone in blood. These two drugs have been designated as an orphan drug. The orphan designation by the FDA was devised to provide financial incentives to drug manufacturers for research and development of drugs with a small target treatment population (less than 200,000); it does not constitute final FDA approval. Orphan designation may also be known as “grant-supported products which have marketing approval.”
Synarel (Nafarelin) is used in the palliative treatment of endometriosis. This drug like other GnRH analogs produces reversible hypo estrogenic state, which is thought to be principally responsible for the beneficial effects observed in endometriosis. A six month course of therapy can provide symptomatic relief and a reduction in endometrial lesions.
Synarel (Nafarelin) is also used for the treatment of central (via activation of the hypothalmic-pituitary-gonadal axis) precocious puberty (true precocious puberty GnRH-dependent precocious puberty, complete isosexual precocity) in children of both sexes and has been designated an orphan drug by the FDA for use in this condition. Precocious puberty is generally defined as the onset of sexual characteristics in girls or boys younger than eight or nine years of age respectively. The principle goals of therapy with GnRH analogs in this condition are to halt the premature development of secondary sexual characteristics and achieve a near normal adult height by slowing linear growth and skeletal maturation.
Trelstar is indicated in the palliative treatment of advanced prostate cancer. It offers an alternative treatment for prostate cancer when orchiectomy or estrogen administration is either not indicated or unacceptable to the patient.
The FDA approves drugs for specific indications that are included in the drug's labeling. When a drug is used for an indication other than those specifically included in the labeling, it is referred to as an off-label, unlabeled use, or grant supported orphan drug use with marketing approval. When coverage is allowed for GnRH therapies, it is done based solely on the FDA labeled indications.
Coverage for treatment of breast cancer beyond the approved FDA labeled indications has been based on two clinical studies, over a two year period, comparing ovarian suppression hormones, such as GnRH analogs to conventional chemotherapeutic agents, such as a combination of cyclophosphamide, methotrexate, and 5-fluorouracil (CMF). Five years after the completion of one study, no difference between goserelin (Zoladex) and CMF was established in the final outcome review. Converting patients from an estrogen receptor (ER) positive to negative state, CMF induces significantly better disease free survival and overall survival.
The American College of Obstetrics and Gynecology (2004) recommended the use of gonadotropin-releasing hormone agonists as a treatment option for chronic pelvic pain since they have been demonstrated to relieve endometriosis-associated pelvic pain. Guidelines from the Royal College of Obstetricians and Gynaecologists (2005) state women with cyclical pelvic pain should be offered a therapeutic trial, using the combined oral contraceptive pill or a GnRH agonist for a period of three- to six-months before having a diagnostic laparoscopy. The Ling (1999) study represents the one small short-term RCT used for support of empiric therapy for management of chronic pelvic pain.
A MEDLINE search through (October 2007) indicated a lack of peer reviewed scientific literature from which conclusions could be made concerning the safety and efficacy of treatment of various other indications mentioned which were not labeled indications by the FDA, including, but not limited to: premenstrual syndrome; menopause or mood related disorders; chronic intestinal disease; cancer of the endometrium, ovary, or liver; benign prostatic hypertrophy; menstrual cycle regulation; and male castration.
