  • 3. DOSAGE FORMS & STRENGTHS

    Bicalutamide Tablets, USP 50 mg Tablets for oral administration.

  • 4. CONTRAINDICATIONS

    4.1. Hypersensitivity

    Bicalutamide Tablets, USP are contraindicated in any patient who has shown a hypersensitivity reaction to the drug or any of the tablet's components. Hypersensitivity reactions including angioneurotic edema and urticaria have been reported [see Adverse Reactions (6.2)].

    4.2. Women

    Bicalutamide Tablets, USP have no indication for women, and should not be used in this population.

    4.3. Pregnancy

    Bicalutamide Tablets, USP may cause fetal harm when administered to a pregnant woman. Bicalutamide Tablets, USP are contraindicated in women, including those who are or may become pregnant. There are no studies in pregnant women using Bicalutamide Tablets, USP. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be appraised of the potential hazard to the fetus [see Use in Specific Populations ( 8.1)].

  • 5. WARNINGS AND PRECAUTIONS

    5.1. Hepatitis

    Rare cases of death or hospitalization due to severe liver injury have been reported post-marketing in association with the use of Bicalutamide Tablets, USP. Hepatotoxicity in these reports generally occurred within the first three to four months of treatment. Hepatitis or marked increases in liver enzymes leading to drug discontinuation occurred in approximately 1% of Bicalutamide Tablets, USP patients in controlled clinical trials.

    Serum transaminase levels should be measured prior to starting treatment with Bicalutamide Tablets, USP, at regular intervals for the first four months of treatment, and periodically thereafter. If clinical symptoms or signs suggestive of liver dysfunction occur (e.g., nausea, vomiting, abdominal pain, fatigue, anorexia, "flu-like" symptoms, dark urine, jaundice, or right upper quadrant tenderness), the serum transaminases, in particular the serum ALT, should be measured immediately. If at any time a patient has jaundice, or their ALT rises above two times the upper limit of normal, Bicalutamide Tablets, USP should be immediately discontinued with close follow-up of liver function.

    5.2. Gynecomastia and Breast Pain

    In clinical trials with Bicalutamide Tablets, USP 150 mg as a single agent for prostate cancer, gynecomastia and breast pain have been reported in up to 38% and 39% of patients, respectively.

    5.3. Glucose Tolerance

    A reduction in glucose tolerance has been observed in males receiving LHRH agonists. This may manifest as diabetes or loss of glycemic control in those with pre-existing diabetes. Consideration should therefore be given to monitoring blood glucose in patients receiving Bicalutamide Tablets, USP in combination with LHRH agonists.

    5.4. Laboratory Tests

    Regular assessments of serum Prostate Specific Antigen (PSA) may be helpful in monitoring the patient's response. If PSA levels rise during Bicalutamide Tablets, USP therapy, the patient should be evaluated for clinical progression. For patients who have objective progression of disease together with an elevated PSA, a treatment-free period of antiandrogen, while continuing the LHRH analog, may be considered.

  • 6. ADVERSE REACTIONS

    Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

    6.1. Clinical Trials Experience

    In patients with advanced prostate cancer treated with Bicalutamide Tablets, USP in combination with an LHRH analog, the most frequent adverse reaction was hot flashes (53%).

    In the multicenter, double-blind, controlled clinical trial comparing Bicalutamide Tablets, USP 50 mg once daily with flutamide 250 mg three times a day, each in combination with an LHRH analog, the following adverse reactions with an incidence of 5% or greater, regardless of causality, have been reported.

    6.2. Postmarketing Experience

    The following adverse reactions have been identified during postapproval use of Bicalutamide Tablets, USP. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

    Uncommon cases of hypersensitivity reactions, including angioneurotic edema and urticaria [see Contraindications (4.1)], and uncommon cases of interstitial lung disease, including interstitial pneumonitis and pulmonary fibrosis, have been reported with Bicalutamide Tablets, USP.

    Reduction in glucose tolerance, manifesting as diabetes or a loss of glycemic control in those with pre-existing diabetes, has been reported during treatment with LHRH agonists.

  • 7. DRUG INTERACTIONS

    Clinical studies have not shown any drug interactions between bicalutamide and LHRH analogs (goserelin or leuprolide). There is no evidence that bicalutamide induces hepatic enzymes.

    In vitro studies have shown that R-bicalutamide is an inhibitor of CYP 3A4 with lesser inhibitory effects on CYP 2C9, 2C19 and 2D6 activity. Clinical studies have shown that with co-administration of Bicalutamide Tablets, USP, mean midazolam (a CYP 3A4 substrate) levels may be increased 1.5 fold (for Cmax) and 1.9 fold (for AUC). Hence, caution should be exercised when Bicalutamide Tablets, USP are co-administered with CYP 3A4 substrates.

    In vitro protein-binding studies have shown that bicalutamide can displace coumarin anticoagulants from binding sites. Prothrombin times should be closely monitored in patients already receiving coumarin anticoagulants who are started on Bicalutamide Tablets, USP and adjustment of the anticoagulant dose may be necessary.

  • 8. USE IN SPECIFIC POPULATIONS

    8.1. Pregnancy

    PREGNANCY CATEGORY X [see Contraindications (4.3)]. Based on its mechanism of action, Bicalutamide Tablets, USP may cause fetal harm when administered to a pregnant woman. Bicalutamide Tablets, USP are contraindicated in women, including those who are or may become pregnant. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to a fetus.

    While there are no human data on the use of Bicalutamide Tablets, USP in pregnancy and Bicalutamide Tablets, USP are not for use in women, it is important to know that maternal use of an androgen receptor inhibitor could affect development of the fetus.

    In animal reproduction studies, male offspring of rats receiving doses of 10 mg/kg/day (approximately 2/3 of clinical exposure at the recommended dose) and above, were observed to have reduced anogenital distance and hypospadias. These pharmacological effects have been observed with other antiandrogens. No other teratogenic effects were observed in rabbits receiving doses up to 200 mg/kg/day (approximately 1/3 of clinical exposure at the recommended dose) or rats receiving doses up to 250 mg/kg/day (approximately 2 times the clinical exposure at the recommended dose).

    8.3. Nursing Mothers

    Bicalutamide Tablets, USP are not indicated for use in women.

    8.4. Pediatric Use

    The safety and effectiveness of Bicalutamide Tablets, USP in pediatric patients have not been established.

    Labeling describing pediatric clinical studies for bicalutamide is approved for AstraZeneca Pharmaceuticals LP's bicalutamide tablet. However, due to AstraZeneca Pharmaceuticals LP's marketing exclusivity rights, a description of those clinical studies is not approved for this bicalutamide labeling.

    8.5. Geriatric Use

    In two studies in patients given 50 or 150 mg daily, no significant relationship between age and steady-state levels of total bicalutamide or the active R-enantiomer has been shown.

    8.6. Hepatic Impairment

    Bicalutamide Tablets, USP should be used with caution in patients with moderate-to-severe hepatic impairment. Bicalutamide Tablets, USP are extensively metabolized by the liver. Limited data in subjects with severe hepatic impairment suggest that excretion of Bicalutamide Tablets, USP may be delayed and could lead to further accumulation. Periodic liver function tests should be considered for hepatic-impaired patients on long-term therapy [see Warnings and Precautions (5.1)].

    No clinically significant difference in the pharmacokinetics of either enantiomer of bicalutamide was noted in patients with mild-to-moderate hepatic disease as compared to healthy controls. However, the half-life of the R-enantiomer was increased approximately 76% (5.9 and 10.4 days for normal and impaired patients, respectively) in patients with severe liver disease (n=4).

    8.7. Renal Impairment

    Renal impairment (as measured by creatinine clearance) had no significant effect on the elimination of total bicalutamide or the active R-enantiomer.

    8.8. Women

    Bicalutamide has not been studied in women.

  • 10. OVERDOSAGE

    Long-term clinical trials have been conducted with dosages up to 200 mg of Bicalutamide Tablets, USP daily and these dosages have been well tolerated. A single dose of Bicalutamide Tablets, USP that results in symptoms of an overdose considered to be life threatening has not been established.

    There is no specific antidote; treatment of an overdose should be symptomatic.

    In the management of an overdose with Bicalutamide Tablets, USP, vomiting may be induced if the patient is alert. It should be remembered that, in this patient population, multiple drugs may have been taken. Dialysis is not likely to be helpful since Bicalutamide Tablets, USP are highly protein bound and is extensively metabolized. General supportive care, including frequent monitoring of vital signs and close observation of the patient, is indicated.

  • 11. DESCRIPTION

    Bicalutamide Tablets, USP contain 50 mg of bicalutamide, a non-steroidal androgen receptor inhibitor with no other known endocrine activity. The chemical name is propanamide, N [4 cyano-3-(trifluoromethyl)phenyl]-3-[(4-fluorophenyl)sulfonyl]-2-hydroxy-2-methyl-,(+-). The structural and empirical formulas are:

    Chemical Structure

    Bicalutamide has a molecular weight of 430.37. The pKa' is approximately 12. Bicalutamide is a fine white to off white powder which is practically insoluble in water at 37°C (5 mg per 1000 mL), slightly soluble in chloroform and absolute ethanol, sparingly soluble in methanol, and soluble in acetone and tetrahydrofuran.

    Bicalutamide Tablets, USP are a racemate with its antiandrogenic activity being almost exclusively exhibited by the R-enantiomer of bicalutamide; the S-enantiomer is essentially inactive.

    The inactive ingredients of Bicalutamide Tablets, USP are lactose monohydrate, magnesium stearate, povidone, crospovidone, sodium lauryl sulfate, polyethylene glycol, hypromellose, and titanium dioxide.

  • 12. CLINICAL PHARMACOLOGY

    12.1. Mechanism of Action

    Bicalutamide Tablets, USP are a non-steroidal androgen receptor inhibitor. It competitively inhibits the action of androgens by binding to cytosol androgen receptors in the target tissue. Prostatic carcinoma is known to be androgen sensitive and responds to treatment that counteracts the effect of androgen and/or removes the source of androgen.

    When Bicalutamide Tablets, USP are combined with luteinizing hormone releasing hormone (LHRH) analog therapy, the suppression of serum testosterone induced by the LHRH analog is not affected. However, in clinical trials with Bicalutamide Tablets, USP as a single agent for prostate cancer, rises in serum testosterone and estradiol have been noted.

    In a subset of patients who have been treated with Bicalutamide Tablets, USP and an LHRH agonist, and who discontinue Bicalutamide Tablets, USP therapy due to progressive advanced prostate cancer, a reduction in Prostate Specific Antigen (PSA) and/or clinical improvement (antiandrogen withdrawal phenomenon) may be observed.

    12.3. Pharmacokinetics

    Absorption

    Bicalutamide is well-absorbed following oral administration, although the absolute bioavailability is unknown. Co-administration of bicalutamide with food has no clinically significant effect on rate or extent of absorption.

    Distribution

    Bicalutamide is highly protein-bound (96%) [see Drug Interactions (7)].

    Metabolism/Elimination

    Bicalutamide undergoes stereospecific metabolism. The S (inactive) isomer is metabolized primarily by glucuronidation. The R (active) isomer also undergoes glucuronidation but is predominantly oxidized to an inactive metabolite followed by glucuronidation. Both the parent and metabolite glucuronides are eliminated in the urine and feces. The S-enantiomer is rapidly cleared relative to the R-enantiomer, with the R-enantiomer accounting for about 99% of total steady-state plasma levels.

    Pharmacokinetics of the active enantiomer of Bicalutamide Tablets, USP in normal males and patients with prostate cancer are presented in Table 3.

  • 13. NONCLINICAL TOXICOLOGY

    13.1. Carcinogenesis, Mutagenesis, Impairment of Fertility

    Two-year oral carcinogenicity studies were conducted in both male and female rats and mice at doses of 5, 15 or 75 mg/kg/day of bicalutamide. A variety of tumor target organ effects were identified and were attributed to the antiandrogenicity of bicalutamide, namely, testicular benign interstitial (Leydig) cell tumors in male rats at all dose levels (the steady-state plasma concentration with the 5 mg/kg/day dose is approximately 2/3 human therapeutic concentrations1) and uterine adenocarcinoma in female rats at 75 mg/kg/day (approximately 1 1/2 times the human therapeutic concentrations1). There is no evidence of Leydig cell hyperplasia in patients; uterine tumors are not relevant to the indicated patient population.

    A small increase in the incidence of hepatocellular carcinoma in male mice given 75 mg/kg/day of bicalutamide (approximately 4 times human therapeutic concentrations1) and an increased incidence of benign thyroid follicular cell adenomas in rats given 5 mg/kg/day (approximately 2/3 human therapeutic concentrations1) and above were recorded. These neoplastic changes were progressions of non-neoplastic changes related to hepatic enzyme induction observed in animal toxicity studies. Enzyme induction has not been observed following bicalutamide administration in man. There were no tumorigenic effects suggestive of genotoxic carcinogenesis.

    A comprehensive battery of both in vitro and in vivo genotoxicity tests (yeast gene conversion, Ames, E. coli, CHO/HGPRT, human lymphocyte cytogenetic, mouse micronucleus, and rat bone marrow cytogenetic tests) has demonstrated that Bicalutamide Tablets, USP does not have genotoxic activity.

    Administration of Bicalutamide Tablets, USP may lead to inhibition of spermatogenesis. The long-term effects of Bicalutamide Tablets, USP on male fertility have not been studied.

    In male rats dosed at 250 mg/kg/day (approximately 2 times human therapeutic concentrations1), the precoital interval and time to successful mating were increased in the first pairing but no effects on fertility following successful mating were seen. These effects were reversed by 7 weeks after the end of an 11-week period of dosing.

    No effects on female rats dosed at 10, 50 and 250 mg/kg/day (approximately 2/3, 1 and 2 times human therapeutic concentrations, respectively1) or their female offspring were observed. Administration of bicalutamide to pregnant females resulted in feminization of the male offspring leading to hypospadias at all dose levels. Affected male offspring were also impotent.

  • 14. CLINICAL STUDIES

    14.1. Bicalutamide Tablets, USP 50 mg Daily in Combination with an LHRH-A

    In a multicenter, double-blind, controlled clinical trial, 813 patients with previously untreated advanced prostate cancer were randomized to receive Bicalutamide Tablets, USP 50 mg once daily (404 patients) or flutamide 250 mg (409 patients) three times a day, each in combination with LHRH analogs (either goserelin acetate implant or leuprolide acetate depot).

    In an analysis conducted after a median follow-up of 160 weeks was reached, 213 (52.7%) patients treated with Bicalutamide Tablets, USP -LHRH analog therapy and 235 (57.5%) patients treated with flutamide-LHRH analog therapy had died. There was no significant difference in survival between treatment groups (see Figure 1). The hazard ratio for time to death (survival) was 0.87 (95% confidence interval 0.72 to 1.05).

    Figure 1 - The Kaplan-Meier probability of death for both antiandrogen treatment groups.

    Figure

    There was no significant difference in time to objective tumor progression between treatment groups (see Figure 2).

    Objective tumor progression was defined as the appearance of any bone metastases or the worsening of any existing bone metastases on bone scan attributable to metastatic disease, or an increase by 25% or more of any existing measurable extraskeletal metastases. The hazard ratio for time to progression of Bicalutamide Tablets, USP plus LHRH analog to that of flutamide plus LHRH analog was 0.93 (95% confidence interval, 0.79 to 1.10).

    Figure 2 - Kaplan-Meier curve for time to progression for both antiandrogen treatment groups.

    Figure

    Quality of life was assessed with self-administered patient questionnaires on pain, social functioning, emotional well being, vitality, activity limitation, bed disability, overall health, physical capacity, general symptoms, and treatment related symptoms. Assessment of the Quality of Life questionnaires did not indicate consistent significant differences between the two treatment groups.

    14.2 Safety Data from Clinical Studies using Bicalutamide Tablets, USP 150 mg

    Bicalutamide Tablets, USP 150 mg are not approved for use either alone or with other treatments.

    Two identical multicenter, randomized, open-label trials comparing Bicalutamide Tablets, USP 150 mg daily monotherapy to castration were conducted in patients that had locally advanced (T3-4, NX, MO) or metastatic (M1) prostate cancer.

    Monotherapy — M1 Group

    Bicalutamide Tablets, USP 150 mg daily are not approved for use in patients with M1 cancer of the prostate. Based on an interim analysis of the two trials for survival, the Data Safety Monitoring Board recommended that Bicalutamide Tablets, USP treatment be discontinued in the M1 patients because the risk of death was 25% (HR 1.25, 95% CI 0.87 to 1.81) and 31% (HR 1.31, 95% CI 0.97 to 1.77) higher in the Bicalutamide Tablets, USP treated group compared to that in the castrated group, respectively.

    Locally Advanced (T3-4, NX, MO) Group

    Bicalutamide Tablets, USP 150 mg daily are not approved for use in patients with locally advanced (T3-4, NX, M0) cancer of the prostate. Following discontinuation of all M1 patients, the trials continued with the T3-4, NX, MO patients until study completion. In the larger trial (N=352), the risk of death was 25% (HR 1.25, 95% CI 0.92 to 1.71) higher in the Bicalutamide Tablets, USP group and in the smaller trial (N=140), the risk of death was 36% (HR 0.64, 95% CI, 0.39 to 1.03) lower in the Bicalutamide Tablets, USP group.

    In addition to the above two studies, there are three other on-going clinical studies that provide additional safety information for Bicalutamide Tablets, USP 150 mg, a dose that is not approved for use. These are three multicenter, randomized, double-blind, parallel group trials comparing Bicalutamide Tablets, USP 150 mg daily monotherapy (adjuvant to previous therapy or under watchful waiting) with placebo, for death or time to disease progression, in a population of 8113 patients with localized or locally advanced prostate cancer.

    Bicalutamide Tablets, USP 150 mg daily are not approved for use as therapy for patients with localized prostate cancer who are candidates for watchful waiting. Data from a planned subgroup analysis of two of these trials in 1627 patients with localized prostate cancer who were under watchful waiting, revealed a trend toward decreased survival in the Bicalutamide Tablets, USP arm after a median follow-up of 7.4 years. There were 294 (37.7%) deaths in the Bicalutamide Tablets, USP treated patients versus 279 (32.9%) deaths in the placebo treated patients (localized watchful waiting group) for a hazard ratio of 1.16 (95% CI 0.99 to 1.37).
