Androxy (Fluoxymesterone) - Summary

 
 



ANDROXY SUMMARY

ANDROXY™
(Fluoxymesterone Tablets, USP)

ANDROXY™ (Fluoxymesterone Tablets, USP) contains fluoxymesterone, a synthetic androgen. The androgens are steroids that develop and maintain primary and secondary male sex characteristics. Androgens are derivatives of cyclopentano-perhydrophenanthrene. Endogenous androgens are C-19 steroids with a side chain at C-17, and with two angular methyl groups. Testosterone is the primary endogenous androgen. Fluoxymesterone is a synthetic derivative of testosterone. In their active form, all drugs in the class have a 17-beta-hydroxy group. 17-alpha-alkylation and halogenation at position 9 (fluoxymesterone) increase the pharmacologic activity per unit weight compared to testosterone when given orally. Fluoxymesterone is a white or practically white odorless, crystalline powder, melting at about 240°C with some decomposition. It is practically insoluble in water, sparingly soluble in alcohol and slightly soluble in chloroform.

Males

ANDROXY™ Tablets are indicated for replacement therapy in conditions associated with a deficiency or absence of endogenous testosterone.

Primary hypogonadism (congenital or acquired) —Testicular failure due to cryptorchidism, bilateral torsion, orchitis, vanishing testis syndrome, or orchidectomy.

Hypogonadotropic hypogonadism (congenital or acquired) —Idiopathic gonadotropin or luteinizing hormone-releasing hormone (LHRH) deficiency, or pituitary-hypothalamic injury from tumors, trauma, or radiation. (Appropriate adrenal cortical and thyroid hormone replacement therapy are still necessary, however, and are actually of primary importance.)

If the above conditions occur prior to puberty, androgen replacement therapy will be needed during the adolescent years for development of secondary sexual characteristics. Prolonged androgen treatment will be required to maintain sexual characteristics in these and other males who develop testosterone deficiency after puberty.

Delayed pubertyANDROXY™ (Fluoxymesterone Tablets, USP) may be used to stimulate puberty in carefully selected males with clearly delayed puberty. These patients usually have a familial pattern of delayed puberty that is not secondary to a pathological disorder; puberty is expected to occur spontaneously at a relatively late date. Brief treatment with conservative doses may occasionally be justified in these patients if they do not respond to psychological support. The potential adverse effect on bone maturation should be discussed with the patient and parents prior to androgen administration. An X-ray of the hand and wrist to determine bone age should be obtained every six months to assess the effect of treatment on the epiphyseal centers (see WARNINGS).

Females

Metastatic mammary cancerANDROXY™ (Fluoxymesterone Tablets, USP) may be used secondarily in women with advancing inoperable metastatic (skeletal) mammary cancer who are one to five years postmenopausal. Primary goals of therapy in these women include ablation of the ovaries. Other methods of counteracting estrogen activity are adrenalectomy, hypophysectomy, and/or antiestrogen therapy. This treatment has been used in premenopausal women with breast cancer who have benefited from oophorectomy and are considered to have a hormone-responsive tumor. Judgment concerning androgen therapy should be made by an oncologist with expertise in this field.

NEWS HIGHLIGHTS

Published Studies Related to Androxy (Fluoxymesterone)

Randomized trial of tamoxifen alone or combined with fluoxymesterone as adjuvant therapy in postmenopausal women with resected estrogen receptor positive breast cancer. North Central Cancer Treatment Group Trial 89-30-52. [2006.07]
PURPOSE: This clinical trial evaluated the addition of fluoxymesterone (Flu) to tamoxifen (Tam) in women with resected early stage breast cancer and attempted to corroborate the findings of superiority for the combination over Tam alone seen in a previous randomized trial in metastatic disease... CONCLUSIONS: This clinical trial did not demonstrate superiority of Tam plus Flu over Tam alone as adjuvant therapy for postmenopausal women with resected early breast cancer known to be ER positive.

Combined endocrine treatment of elderly postmenopausal patients with metastatic breast cancer. A randomized trial of tamoxifen vs. tamoxifen + aminoglutethimide and hydrocortisone and tamoxifen + fluoxymesterone in women above 65 years of age. [2000.05]
The efficacy of combined endocrine therapy with tamoxifen (TAM), aminoglutethimide (AG), and hydrocortisone (H) or tamoxifen and fluoxymesterone (FLU) was evaluated against treatment with tamoxifen alone in 311 patients above 65 years of age with a first recurrence of a metastatic breast cancer.

Randomized comparison of megestrol acetate versus dexamethasone versus fluoxymesterone for the treatment of cancer anorexia/cachexia. [1999.10]
PURPOSE: Previous double-blind, placebo-controlled, randomized clinical trials have demonstrated that both corticosteroids and progestational agents do partially alleviate cancer anorexia/cachexia. Pilot information suggested that an anabolic corticosteroid might also improve appetite in patients with cancer anorexia/cachexia. The current trial was developed to compare and contrast a progestational agent, a corticosteroid, and an anabolic corticosteroid for the treatment of cancer anorexia/cachexia... CONCLUSION: Whereas fluoxymesterone clearly seems to be an inferior choice for treating cancer anorexia/cachexia, megestrol acetate and dexamethasone have similar appetite stimulating efficacy but differing toxicity profiles.

Combination hormonal therapy with tamoxifen plus fluoxymesterone versus tamoxifen alone in postmenopausal women with metastatic breast cancer. An updated analysis. [1991.02.15]
A randomized trial was performed to determine if therapy with tamoxifen (TAM) plus fluoxymesterone (FLU) was more efficacious than TAM alone for postmenopausal women with metastatic breast cancer... Although these data require confirmation in a prospective randomized trial, they suggest that there is a substantive therapeutic advantage for TAM plus FLU over TAM alone in elderly women with ER of 10 fmol or greater.

Tamoxifen and fluoxymesterone versus tamoxifen and danazol in metastatic breast cancer--a randomized study. [1988.09]
A prospective randomized trial of tamoxifen and fluoxymesterone versus tamoxifen and danazol in metastatic breast cancer was conducted from December 1980 to September 1985. Patients were eligible regardless of site of disease, estrogen receptor status, or age... We conclude that the response rates to the combinations of tamoxifen and fluoxymesterone or tamoxifen and danazol reported are equivalent in this study but that the increased toxicity with tamoxifen and fluoxymesterone would make tamoxifen and danazol the treatment of choice if a combination were to be used.

Clinical Trials Related to Androxy (Fluoxymesterone)

Dose-finding Study of Hexaminolevulinate (HAL) Photodynamic Therapy (PDT) to Treat Cervical Neoplasia [Recruiting]
An effective and safe medical therapy would be most welcome to reduce the need for surgical interventions and related adverse events and psychological impact on patients with cervical cancer precursors. In this clinical trial, the investigators propose to evaluate the efficacy and safety of photodynamic therapy (PDT) using hexaminolevulinate (HAL) for mild to moderate-grade CIN (grade 1-2).

Hexaminolevulinate (HAL) Photodynamic Therapy (PDT) of Cervical Intraepithelial Neoplasia (CIN) Grade 1 [Recruiting]
The study will examine the effect of HAL vs placebo photodynamic therapy of low-grade cervical precancerous lesions (dysplasia) in women.

HIV Acquired Lipodystrophy (HAL) Classification, Measurement and Fat Response to Thiazolidinedione (TZD) (Pioglitazone) [Recruiting]
This study is being done to better understand why people with HIV who have taken drugs for HIV begin to show abnormal changes in fat loss or fat gain in their bodies. This condition is called lipodystrophy.

Patients who take medicine for HIV and who have lipodystrophy report loss of subcutaneous (sc) fat from the arms, legs, and face and excess fat gain in the neck and truncal region. They also more likely to have problems with insulin in the body, high fat levels in the blood and diabetes. The reason that lipodystrophy develops is not fully understood although some HIV drugs have are very likely the cause. The complications pose an increased risk of fat blockage forming in the arteries making you more at risk for heart problems in the future. Changes in body fat can cause physical discomfort and psychological distress. Management of these problems can be a challenge for the patient's doctor.

The investigators propose data collection to determine if there is more than one reason why this might happen in some people and not in others. Laboratory samples being collected: 1) special imaging of the liver; 2) fat collected by needle from the mid thigh and mid-shoulder areas; 3) blood samples to measure the virus, t-cells, fats, and other markers of how the patient's body is handling the virus.

This study is being done because science does not fully understand why some patients with HIV who take medicines for the virus have abnormal fat loss or gain and some do not. This research study is intended to help us better understand why and how this happens.

A Study of Topical Hexaminolevulinate (HAL) Photodynamic Therapy (PDT) and a Phase III Comparative Treatment Study of HAL PDT in Female Genital Erosive Lichen Planus (GELP) [Not yet recruiting]

Immunotherapy Study in Progressive or Relapsed Non-Small Cell Lung Cancer [Recruiting]
The purpose of this study is to assess overall survival of anti-tumor immunization using HyperAcuteŽ-Lung immunotherapy versus Docetaxel in patients with progressed or relapsed non-small cell lung cancer (NSCLC) that have been previously treated.
