ADVERSE REACTIONS SECTION.

6 ADVERSE REACTIONS. Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Adverse reactions that occurred in more than 10% of patients receiving Bicalutamide Tablets plus an LHRH-A were: hot flashes, pain (including general, back, pelvic and abdominal), asthenia, constipation, infection, nausea, peripheral edema, dyspnea, diarrhea, hematuria, nocturia and anemia.

Postmarketing Experience The following adverse reactions have been identified during postapproval use of Bicalutamide Tablets. Because these reactions are reported voluntarily from population of uncertain size, it is not always possible to reliably estimate their frequency or establish 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. Reduction in glucose tolerance, manifesting as diabetes or loss of glycemic control in those with pre-existing diabetes, has been reported during treatment with LHRH agonists.

CARCINOGENESIS & MUTAGENESIS & IMPAIRMENT OF FERTILITY SECTION.

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. 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 mg/kg/day dose is approximately 2/3 human therapeutic concentrations) and uterine adenocarcinoma in female rats at 75 mg/kg/day (approximately 1/2 times the human therapeutic concentrations). There is no evidence of Leydig cell hyperplasia in patients; uterine tumors are not relevant to the indicated patient population. small increase in the incidence of hepatocellular carcinoma in male mice given 75 mg/kg/day of bicalutamide (approximately times human therapeutic concentrations) and an increased incidence of benign thyroid follicular cell adenomas in rats given mg/kg/day (approximately 2/3 human therapeutic concentrations) 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. 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 does not have genotoxic activity. Administration of bicalutamide may lead to inhibition of spermatogenesis. The long-term effects of bicalutamide on male fertility have not been studied. In male rats dosed at 250 mg/kg/day (approximately times human therapeutic concentrations), 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 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, and times human therapeutic concentrations, respectively) 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. Based on maximum dose of 50 mg/day of bicalutamide for an average 70 kg patient.

CLINICAL PHARMACOLOGY SECTION.

12 CLINICAL PHARMACOLOGY. 12.1 Mechanism of Action. Bicalutamide is 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 is 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 as single agent for prostate cancer, rises in serum testosterone and estradiol have been noted. In subset of patients who have been treated with bicalutamide and an LHRH agonist, and who discontinue bicalutamide therapy due to progressive advanced prostate cancer, 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 (inactive) isomer is metabolized primarily by glucuronidation. The (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 in normal males and patients with prostate cancer are presented in Table 2.Table 2Css mean steady-state concentrationParameter Mean Standard Deviation Normal Males (n=30) Apparent Oral Clearance (L/hr) 0.320 0.103 Single Dose Peak Concentration 0.7680.178 (ug/mL) Single Dose Time to Peak 31.314.6 Concentration (hours) Half-life (days) 5.8 2.29 Patients with Prostate Cancer (n=40)Css (ug/mL) 8.939 3.504.

CLINICAL STUDIES SECTION.

14 CLINICAL STUDIES. 14.1. Bicalutamide 50 mg Daily in Combination with an LHRH-A In multicenter, double-blind, controlled clinical trial, 813 patients with previously untreated advanced prostate cancer were randomized to receive bicalutamide 50 mg once daily (404 patients) or flutamide 250 mg (409 patients) three times day, each in combination with LHRH analogs (either goserelin acetate implant or leuprolide acetate depot). In an analysis conducted after median follow-up of 160 weeks was reached, 213 (52.7%) patients treated with bicalutamide-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 - The Kaplan-Meier probability of death for both antiandrogen treatment groups. 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 plus LHRH analog to that of flutamide plus LHRH analog was 0.93 (95% confidence interval, 0.79 to 1.10).Figure - Kaplan-Meier curve for time to progression for both antiandrogen treatment groups. 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 150 mg. Bicalutamide 150 mg is not approved for use either alone or with other treatments.Two identical multicenter, randomized, open-label trials comparing bicalutamide 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 150 mg daily is 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 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 treated group compared to that in the castrated group, respectively. Locally Advanced (T3-4, NX, MO) Group Bicalutamide 150 mg daily is 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 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 group. In addition to the above two studies, there are three other on-going clinical studies that provide additional safety information for bicalutamide 150 mg, dose that is not approved for use. These are three multicenter, randomized, double-blind, parallel group trials comparing bicalutamide 150 mg daily monotherapy (adjuvant to previous therapy or under watchful waiting) with placebo, for death or time to disease progression, in population of 8113 patients with localized or locally advanced prostate cancer. Bicalutamide 150 mg daily is not approved for use as therapy for patients with localized prostate cancer who are candidates for watchful waiting. Data from planned subgroup analysis of two of these trials in 1627 patients with localized prostate cancer who were under watchful waiting, revealed trend toward decreased survival in the bicalutamide arm after median follow-up of 7.4 years. There were 294 (37.7%) deaths in the bicalutamide treated patients versus 279 (32.9%) deaths in the placebo treated patients (localized watchful waiting group) for hazard ratio of 1.16 (95% CI 0.99 to 1.37)..

DOSAGE & ADMINISTRATION SECTION.

2 DOSAGE AND ADMINISTRATION. The recommended dose for Bicalutamide Tablet therapy in combination with an LHRH analog is one 50 mg tablet once daily (morning or evening), with or without food. It is recommended that Bicalutamide Tablets be taken at the same time each day. Treatment with Bicalutamide Tablets should be started at the same time as treatment with an LHRH analog. The recommended dose for Bicalutamide Tablets therapy in combination with an LHRH analog is one 50 mg tablet once daily (morning or evening). (2). 2.1 Dosage Adjustment in Renal Impairment No dosage adjustment is necessary for patients with renal impairment [see Use in Specific Populations (8.7.) . 2.2 Dosage Adjustment in Hepatic Impairment No dosage adjustment is necessary for patients with mild to moderate hepatic impairment. In patients with severe liver impairment (n=4), although there was 76% increase in the half-life (5.9 and 10.4 days for normal and impaired patients, respectively) of the active enantiomer of bicalutamide no dosage adjustment is necessary [see Use in Specific Populations (8.6.).

3 DOSAGE FORMS AND STRENGTHS. Bicalutamide Tablets 50 mg for oral administration.. 50 mg tablets (3).

DRUG INTERACTIONS SECTION.

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, 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 is 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 and adjustment of the anticoagulant dose may be necessary.. R-bicalutamide is an inhibitor of CYP 3A4; therefore, caution should be used when Bicalutamide Tablets are co-administered with CYP 3A4 substrates. (7)Prothrombin times should be closely monitored in patient already receiving coumarin anticoagulants who are started on Bicalutamide Tablets. (7).

INFORMATION FOR PATIENTS SECTION.

17 PATIENT COUNSELING INFORMATION. Patients should be informed that therapy with Bicalutamide Tablets and the LHRH analog should be started at the same time and that they should not interrupt or stop taking these medications without consulting their physician. During treatment with Bicalutamide Tablets, somnolence has been reported, and those patients who experience this symptom should observe caution when driving or operating machines. Patients should be informed that diabetes, or loss of glycemic control in patients with pre-existing diabetes has been reported during treatment with LHRH agonists. Consideration should therefore be given to monitoring blood glucose in patients receiving Bicalutamide Tablets in combination with LHRH agonists.Manufactured for:Kremers Urban, LLCPrinceton, NJ 08540, USAby:Cipla LtdVirgonagar,Bangalore-560049.

NONCLINICAL TOXICOLOGY SECTION.

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. 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 mg/kg/day dose is approximately 2/3 human therapeutic concentrations) and uterine adenocarcinoma in female rats at 75 mg/kg/day (approximately 1/2 times the human therapeutic concentrations). There is no evidence of Leydig cell hyperplasia in patients; uterine tumors are not relevant to the indicated patient population. small increase in the incidence of hepatocellular carcinoma in male mice given 75 mg/kg/day of bicalutamide (approximately times human therapeutic concentrations) and an increased incidence of benign thyroid follicular cell adenomas in rats given mg/kg/day (approximately 2/3 human therapeutic concentrations) 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. 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 does not have genotoxic activity. Administration of bicalutamide may lead to inhibition of spermatogenesis. The long-term effects of bicalutamide on male fertility have not been studied. In male rats dosed at 250 mg/kg/day (approximately times human therapeutic concentrations), 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 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, and times human therapeutic concentrations, respectively) 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. Based on maximum dose of 50 mg/day of bicalutamide for an average 70 kg patient.

NURSING MOTHERS SECTION.

8.3 Nursing Mothers. Bicalutamide Tablets are not indicated for use in women.

OVERDOSAGE SECTION.

10 OVERDOSAGE. Long-term clinical trials have been conducted with dosages up to 200 mg of bicalutamide daily and these dosages have been well tolerated. single dose of bicalutamide 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, 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 is highly protein bound and is extensively metabolized. General supportive care, including frequent monitoring of vital signs and close observation of the patient, is indicated.

PREGNANCY SECTION.

8.1 Pregnancy. PREGNANCY CATEGORY X. [see Contraindications (4.3)]. Based on its mechanism of action, Bicalutamide Tablets may cause fetal harm when administered to pregnant woman. Bicalutamide Tablets 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 fetus. While there are no human data on the use of bicalutamide in pregnancy and bicalutamide is 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 times the clinical exposure at the recommended dose).

SPL UNCLASSIFIED SECTION.

2.1 Dosage Adjustment in Renal Impairment No dosage adjustment is necessary for patients with renal impairment [see Use in Specific Populations (8.7.).

STORAGE AND HANDLING SECTION.

16.1. Storage and Handling Store at controlled room temperature, 20-25C (68-77F).

USE IN SPECIFIC POPULATIONS SECTION.

8 USE IN SPECIFIC POPULATIONS. Pediatric patients: Labeling describing pediatric clinical studies for bicalutamide is approved for AstraZeneca Pharmaceuticals LPs bicalutamide tablet. However, due to AstraZeneca Pharmaceuticals LPs marketing exclusivity rights, description of those clinical studies is not approved for this bicalutamide labeling. (8.4). 8.1 Pregnancy. PREGNANCY CATEGORY X. [see Contraindications (4.3)]. Based on its mechanism of action, Bicalutamide Tablets may cause fetal harm when administered to pregnant woman. Bicalutamide Tablets 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 fetus. While there are no human data on the use of bicalutamide in pregnancy and bicalutamide is 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 times the clinical exposure at the recommended dose).. 8.3 Nursing Mothers. Bicalutamide Tablets are not indicated for use in women.. 8.4 Pediatric Use. The safety and effectiveness of Bicalutamide Tablets in pediatric patients have not been established.Labeling describing pediatric clinical studies for bicalutamide is approved for AstraZeneca Pharmaceuticals LPs bicalutamide tablet. However, due to AstraZeneca Pharmaceuticals LPs marketing exclusivity rights, 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 should be used with caution in patients with moderate-to-severe hepatic impairment. Bicalutamide Tablets are extensively metabolized by the liver. Limited data in subjects with severe hepatic impairment suggest that excretion of bicalutamide 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.

WARNINGS AND PRECAUTIONS SECTION.

5 WARNINGS AND PRECAUTIONS. Severe hepatic changes and hepatic failure have been observed rarely. Monitor serum transaminase levels prior to starting treatment with Bicalutamide Tablets, at regular intervals for the first four months of treatment and periodically thereafter, and for symptoms or signs suggestive of hepatic dysfunction. Use Bicalutamide Tablets with caution in patients with hepatic impairment. (5.1) Gynecomastia and breast pain have been reported during treatment with Bicalutamide Tablets 150 mg when used as single agent. (5.2.)Bicalutamide Tablets are used in combination with LHRH agonist. LHRH agonists have been shown to cause reduction in glucose tolerance in males. Consideration should be given to monitoring blood glucose in patients receiving Bicalutamide Tablets in combination with LHRH agonists. (5.3.)Monitoring Prostate Specific Antigen (PSA) is recommended. Evaluate for clinical progression if PSA increases. (5.4.). Severe hepatic changes and hepatic failure have been observed rarely. Monitor serum transaminase levels prior to starting treatment with Bicalutamide Tablets, at regular intervals for the first four months of treatment and periodically thereafter, and for symptoms or signs suggestive of hepatic dysfunction. Use Bicalutamide Tablets with caution in patients with hepatic impairment. (5.1) Gynecomastia and breast pain have been reported during treatment with Bicalutamide Tablets 150 mg when used as single agent. (5.2.). Bicalutamide Tablets are used in combination with LHRH agonist. LHRH agonists have been shown to cause reduction in glucose tolerance in males. Consideration should be given to monitoring blood glucose in patients receiving Bicalutamide Tablets in combination with LHRH agonists. (5.3.). Monitoring Prostate Specific Antigen (PSA) is recommended. Evaluate for clinical progression if PSA increases. (5.4.). 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. 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 patients in controlled clinical trials. Serum transaminase levels should be measured prior to starting treatment with bicalutamide, 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 patient has jaundice, or their ALT rises above two times the upper limit of normal, Bicalutamide Tablets should be immediately discontinued with close follow-up of liver function. 5.2. Gynecomastia and Breast Pain In clinical trials with Bicalutamide Tablets 150 mg as 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 preexisting diabetes. Consideration should therefore be given to monitoring blood glucose in patients receiving bicalutamide in combination with LHRH agonists. 5.4. Laboratory Tests Regular assessments of serum Prostate Specific Antigen (PSA) may be helpful in monitoring the patients response. If PSA levels rise during bicalutamide therapy, the patient should be evaluated for clinical progression. For patients who have objective progression of disease together with an elevated PSA, treatment-free period of antiandrogen, while continuing the LHRH analog, may be considered.
