GnRH analogs are a group of hormonal drugs consisting of GnRH agonists and antagonists, both of which suppress pituitary hormones. GnRH agonists typically act over several days and GnRH antagonists act quickly within several hours. Affecting the pituitary gland in the brain, GnRH analogs suppress function of the ovaries and testes, blocking the production of testosterone in males and estrogen in females. Repeated administration of these drugs will cause gonadal hormone dependent tissues/organs to reduce or cease activity, such as the normal prostate gland that is dependent on testosterone for growth and function. This effect is reversible on discontinuation of the drug therapy.
Drugs classified as GnRH analogs include, but are not limited to: degarelix (Firmagon®),goserelin acetate (Zoladex®), histrelin acetate (Vantas® 12 month implant; Supprelin® LA 12 month implant), leuprolide acetate (Lupron Depot®, Lupron Depot-Ped®, Eligard®), nafarelin acetate (Synarel Nasal Spray®), and triptorelin pamoate (Trelstar®, Trelstar LA®, Trelstar Depot®). Currently, the brand Lupron (leuprolide acetate) is not being marketed in the United States; however, the brands Lupron Depot, Lupron Depot-Ped and Eligard remain available. There are both Food and Drug Administration (FDA) approved and non-FDA approved indications for these drugs. The non-FDA approved indications listed in this document are based on drug compendia (The National Comprehensive Cancer Network® NCCN Drugs & Biologic Compendium™, DrugPoints® Compendium, and the American Hospital Formulary Service®) and published peer reviewed literature as detailed in CG-DRUG-01 Off-Label Drug and Approved Orphan Drug Use.
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.
Breast cancer is the most common cancer diagnosed in women today with the exception of skin cancer. Suppression of ovarian function with the use of goserelin acetate or leuprolide acetate has been shown to be effective in the treatment of hormone receptor positive breast cancer in pre- or peri-menopausal women. Two clinical studies (Jonat, 2002; Jakesz, 2002) compared 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 acetate (Zoladex) and CMF was established in the final outcome review. Converting subjects from an estrogen receptor positive to negative state, CMF induces significantly better disease free survival and overall survival. Men with breast cancer should be treated similarly to postmenopausal women, except that use of an aromatase inhibitor is ineffective without concomitant suppression of testicular steroidogenesis (NCCN, 2013).
There are several small studies in the peer reviewed published literature assessing the role of leuprolide acetate as a treatment for ovarian cancer. Fishman (1996) evaluated six women with recurrent or persistent ovarian granulosa cell tumor who were treated with monthly leuprolide acetate injections. Cessation of disease progression was noted in five subjects. The sixth subject remained disease free since her primary cytoreductive surgery while on adjuvant therapy with leuprolide acetate for 24 months. There were no major side effects noted and the treatment was well tolerated. The authors concluded that a reasonable disease progression-free interval occurred and leuprolide treatment should be considered for further trials of therapy. Balbi (2004) reported on a study in which 12 women with advanced ovarian cancer previously treated with paclitaxel were administered leuprolide on days 1, 8, and 28. Progression free survival was six months and the treatment was well tolerated. The authors noted: "the high tolerability and the results obtained with leuprolide versus platinum in second-line therapy might permit a better use of the analogs for advanced ovarian cancer."
Prostate cancer is the most common form of cancer, other than skin cancer, among men. Wilt and colleagues (2008) report that approximately 90% of men with prostate cancer have disease confined to the prostate gland (clinically localized disease). GnRH analogs are commonly used in the treatment of prostate cancer under specific conditions.
Men with prostate cancer are categorized according to their recurrence risk into those with clinically localized disease at low, intermediate and high risk of recurrence, or those with locally advanced disease at very high risk of recurrence, or those with metastatic disease. The 2013 NCCN Prostate Cancer Guideline includes the following additional information defining prostate cancer recurrence risk categories:
Low risk category includes men with tumors stage T1-T2a, low Gleason score (less than or equal to 6), and serum PSA level below 10.
Intermediate risk category includes men with any T2b to T2c cancer, Gleason score of 7, or PSA value of 10-20 ng/ mL. Those with multiple adverse factors may be shifted into the high risk category.
Men with prostate cancer that is clinically localized Stage T3a or Gleason score 8-10 or preoperative PSA level greater than 20 ng/mL are categorized by the NCCN Guideline Panel as high risk for recurrence after definitive therapy, and those at very high risk of recurrence have Stage T3b to T4 (locally advanced) disease.
Neoadjuvant androgen deprivation therapy (which includes GnRH analogs) may be used to shrink the prostate to an acceptable size prior to brachytherapy (NCCN Clinical Practice Guideline for Prostate Cancer, 2013). The American Academy of Urology (2008) indicates that there is evidence of benefit from hormone therapy prior to cryosurgery for downsizing purposes. The American Cancer Society (2013) reports that androgen deprivation therapy may be used before radiation to shrink the prostate cancer to make other treatments more effective. In addition, several early studies demonstrated reduction of the size of the prostate with GnRH prior to cryosurgery or external beam radiation therapy for treatment of prostate cancer. Shearer and colleagues (1992) reported a significant reduction in prostate volume achieved with GNRH (goserelin) in 20 of 22 individuals prior to external beam radiotherapy. These authors also noted that hormonal therapy allows for reduction of tumor volume and hence the size of the radiotherapy field. Wong and colleagues (1997) treated 47 cases of prostate cancer with androgen ablation (leuprolide acetate) prior to cryosurgery to shrink the gland. Wilson and colleagues (2004) report that GnRH antagonists clearly provide efficacy in downsizing the prostate and urologists are utilizing androgen deprivation therapy before surgical and radiation procedures for prostate cancer. Specialty consensus review also recommends short-term use of androgen deprivation therapy prior to brachytherapy, cryosurgery or external beam radiation therapy in men with large prostates (50 grams or more) for a period of 3-9 months prior to therapy to shrink the gland in order to make radiation or cryotherapy feasible. If the gland is too large, therapy may be inadequate.
Central Precocious Puberty
Central precocious puberty (CPP) refers to premature activation of the hypothalamic-pituitary-gonadal axis (Eugster, 2007; Phillip, 2005). Carel and colleagues (2009), on behalf of members of the European Society for Pediatric Endocrinology, indicated that precocious puberty is the development of secondary sexual characteristics before eight years of age in girls and nine years of age in boys. Treatment may be initiated following the establishment of a clinical diagnosis of CPP, however the condition may not be detected or evaluated at onset and treatment can sometimes be started after age eight or nine. Discontinuation of therapy is a clinical decision and there is insufficient evidence to rely on any one clinical variable to make that decision. In studies examined, wishes of the individual receiving treatment, family and the physician's decision were stated as deciding factors for cessation of treatment. However, discontinuation guidance is provided in the product label. For example, the Supprelin LA product label indicates that discontinuation "should be considered at the discretion of the physician and at the appropriate time point for the onset of puberty (approximately 11 years for females and 12 years for males)."
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 3-6 months before having a diagnostic laparoscopy.
The American College of Obstetrics and Gynecology (ACOG) (2004; reaffirmed 2008) practice bulletin for chronic pelvic pain includes the following Level A recommendation and conclusion which is stated to be based on good and consistent scientific evidence:
Level B recommendations which are based on limited or inconsistent scientific evidence include the following:
The ACOG (2010) practice bulletin for the management of endometriosis includes the following Level A recommendations and conclusions:
Level B recommendations include the following:
The Ling (1999) study is a small, short-term, randomized controlled trial (RCT) used for support of empiric therapy for management of chronic pelvic pain.
The effect of GnRH analogs on fertility preservation during chemotherapy has also been investigated. Del Mastro and colleagues (2011) indicated that the use of triptorelin to induce temporary ovarian suppression during chemotherapy in premenopausal women with early-stage breast cancer reduced the occurrence of chemotherapy-induced early menopause. In another study, Gerber and colleagues (2011) concluded that premenopausal women with breast cancer receiving goserelin acetate during chemotherapy did not experience statistically significantly less amenorrhea six months after end of chemotherapy compared with those receiving chemotherapy alone. Although the resumption of menses was more favorable in the triptorelin study, the actual number of live births between both groups was not significantly different. Published data regarding the efficacy of GnRH in protecting the ovaries during chemotherapy is conflicting and it unclear at this time if these agents are able preserve fertility.
The uses of GnRH analogs considered to be medically necessary in this document have sufficient evidence available to support them. However, there is a lack of scientific evidence found from which conclusions could be made concerning the safety and efficacy of treating various other indications, including, but not limited to: premenstrual syndrome; fertility preservation during chemotherapy, menopause or mood related disorders; cancer of the endometrium, cancer of the liver; benign prostatic hypertrophy; male castration, and to stop pubertal development in order to maximize growth for children of short stature on growth hormones.
Adjuvant therapy: Treatment given after the primary treatment to increase the chances of a cure; may include chemotherapy, radiation, hormone, or biological therapy.
Advanced prostate cancer: Disease that has spread beyond the prostate to surrounding tissues or distant organs.
Androgen deprivation therapy (also known as androgen ablation or androgen suppression): Treatment to suppress or block the production or action of male hormones. This is done by having the testicles removed, by taking female sex hormones, or by taking drugs called antiandrogens or GnRH analogs.
Brachytherapy (also known as internal radiation): A type of radiation treatment used to stop the growth of cancer cells by implanting radioactive material directly into the tumor or into the surrounding tissues.
Cancer staging: The process of determining how much cancer there is in the body and where it is located; describes the extent or severity of an individual's cancer based on the extent of the original (primary) tumor and the extent of spread in the body.
Central precocious puberty: The beginning of secondary sexual characteristics before age 8 in girls and age 9 in boys.
Chronic pelvic pain: Noncyclical pain lasting 6 or more months that localizes to the anatomic pelvis, anterior abdominal wall at or below the umbilicus, the lumbosacral back, or the buttocks, and is of sufficient severity to cause functional disability or lead to medical care (ACOG, 2004).
Clinically localized prostate cancer: Cancer presumed to be confined within the prostate based on pre-treatment findings such as physical exam, imaging, and biopsy findings.
Cryosurgery (also called cryotherapy or cryosurgical ablation): Is the use of extreme cold produced by liquid nitrogen (or argon gas) to destroy abnormal tissue. Cryosurgery may be used to treat tumors on the skin (external tumors), such as basal cell carcinoma, or tumors inside the body (internal tumors), such as prostate cancer.
External beam radiation therapy (EBRT) (also known as teletherapy): A form of therapy using radiation to stop the growth of cancer cells. A linear accelerator directs a photon or electron beam from outside the body through normal body tissue to reach the cancer and the radiation is given 5 days a week for a period of 3 to 8 weeks.
Gleason Grading System: A prostate cancer grading system based on a number range from one to five; the lower the number, the lower the grade, and the slower the cancer growth.
Gleason score: Represents the sum of the two most common Gleason grades observed by the pathologist on a specimen, the first number is the most frequent grade seen.
Locally advanced disease (prostate cancer): Cancer that has spread from where it started to nearby tissue or lymph nodes.
Metastatic: The spread of cancer from one part of the body to another; a metastatic tumor contains cells that are like those in the original (primary) tumor and have spread.
Risk of recurrence (prostate cancer):
Low risk of recurrence: Men with tumors stage T1-T2a, low Gleason score (less than or equal to 6), and serum PSA level below 10.
Intermediate risk of recurrence: Men with any T2b to T2c cancer or Gleason score of 7 or PSA value of 10-20 ng/mL.
High risk of recurrence: Men with prostate cancer that is clinically localized stage T3a or Gleason score 8-10, or PSA level greater than 20 ng/mL after definitive therapy.
Very high risk of recurrence: Men with Stage T3b to T4 (locally advanced) disease.
