ADVERSE REACTIONS SECTION.


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. Adverse reactions that occurred in more than 10% of patients receiving CASODEX 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. (6.1) To report SUSPECTED ADVERSE REACTIONS, contact AstraZeneca Pharmaceuticals LP at 1-800-236-9933 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch 6.1. Clinical Trials Experience In patients with advanced prostate cancer treated with CASODEX in combination with an LHRH analog, the most frequent adverse reaction was hot flashes (53%). In the multi-center, double-blind, controlled clinical trial comparing CASODEX 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.

Postmarketing Experience The following adverse reactions have been identified during post-approval use of CASODEX. 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. Respiratory disorders: Interstitial lung disease (some fatal) including interstitial pneumonitis and pulmonary fibrosis, most often at doses greater than 50 mg. Hemorrhage: Increased PT/INR due to interaction between coumarin anticoagulants and CASODEX. Serious bleeding reported. [see Warnings and Precautions (5.2)] Skin and subcutaneous tissue disorders: Photosensitivity

INDICATIONS & USAGE SECTION.


1. INDICATIONS AND USAGE CASODEX 50 mg daily is indicated for use in combination therapy with a luteinizing hormone-releasing hormone (LHRH) analog for the treatment of Stage D2 metastatic carcinoma of the prostate. CASODEX 150 mg daily is not approved for use alone or with other treatments [see Clinical Studies (14.2)]. CASODEX 50 mg is an androgen receptor inhibitor indicated for use in combination therapy with a luteinizing hormone-releasing hormone (LHRH) analog for the treatment of Stage D2 metastatic carcinoma of the prostate. (1) CASODEX 150 mg daily is not approved for use alone or with other treatments. (1)

DOSAGE & ADMINISTRATION SECTION.


2. DOSAGE AND ADMINISTRATION The recommended dose for CASODEX therapy in combination with an LHRH analog is one 50 mg tablet once daily (morning or evening). (2) 2.1. Recommended Dose and Schedule The recommended dose for CASODEX 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 CASODEX be taken at the same time each day. Treatment with CASODEX should be started at the same time as treatment with an LHRH analog. If a dose of CASODEX is missed, take the next dose at the scheduled time. Do not take the missed dose and do not double the next dose. 2.2. Dosage Adjustment in Renal Impairment No dosage adjustment is necessary for patients with renal impairment [see Use in Specific Populations (8.7)]. 2.3. 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 a 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)].

DESCRIPTION SECTION.


11. DESCRIPTION CASODEX (bicalutamide) tablets 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: 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 37C (5 mg per 1000 mL), slightly soluble in chloroform and absolute ethanol, sparingly soluble in methanol, and soluble in acetone and tetrahydrofuran. CASODEX is 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 CASODEX Tablets are lactose, magnesium stearate, hypromellose, polyethylene glycol, polyvidone, sodium starch glycollate, and titanium dioxide.

OVERDOSAGE SECTION.


10. OVERDOSAGE Long-term clinical trials have been conducted with dosages up to 200 mg of CASODEX daily and these dosages have been well tolerated. A single dose of CASODEX 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 CASODEX, 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 CASODEX 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.

WARNINGS AND PRECAUTIONS SECTION.


5. WARNINGS AND PRECAUTIONS Severe hepatic injury and fatal hepatic failure have been observed. Monitor serum transaminase levels prior to starting treatment with CASODEX, at regular intervals for the first four months of treatment and periodically thereafter, and for symptoms or signs suggestive of hepatic dysfunction. Use CASODEX with caution in patients with hepatic impairment. (5.1) Hemorrhage with Concomitant Use of Coumarin Anticoagulant. Closely monitor the Prothrombin Time (PT) and International Normalized Ratio (INR), and adjust the anticoagulant dose as needed. (5.2) Gynecomastia and breast pain have been reported during treatment with CASODEX 150 mg when used as a single agent. (5.3) CASODEX is used in combination with an LHRH agonist. LHRH agonists have been shown to cause a reduction in glucose tolerance in males. Consideration should be given to monitoring blood glucose in patients receiving CASODEX in combination with LHRH agonists. (5.4) Monitoring Prostate Specific Antigen (PSA) is recommended. Evaluate for clinical progression if PSA increases. (5.5) 5.1. Hepatitis Cases of death or hospitalization due to severe liver injury (hepatic failure) have been reported postmarketing in association with the use of CASODEX. 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 CASODEX patients in controlled clinical trials. Serum transaminase levels should be measured prior to starting treatment with CASODEX, 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, CASODEX should be immediately discontinued with close follow-up of liver function. 5.2. Hemorrhage with Concomitant Use of Coumarin Anticoagulant In the postmarketing setting, there have been reports of excessive prolongation of the prothrombin time (PT) and International Normalized Ratio (INR) days to weeks after the introduction of CASODEX in patients who were previously stable on coumarin anticoagulants. Some patients had serious bleeding including intracranial, retroperitoneal, and gastrointestinal requiring blood transfusion and/or administration of vitamin K. Closely monitor the PT/INR, and adjust the anticoagulant dose as needed [see Drug Interactions (7) and Adverse Reactions (6.2)]. 5.3. Gynecomastia and Breast Pain 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 CASODEX in combination with LHRH agonists. 5.4. Glucose ToleranceA 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 CASODEX in combination with LHRH agonists. 5.5. Laboratory Tests Regular assessments of serum Prostate Specific Antigen (PSA) may be helpful in monitoring the patients response. If PSA levels rise during CASODEX 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.

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 CASODEX, 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 CASODEX is co-administered with CYP 3A4 substrates. In vitro protein binding studies have shown that bicalutamide can displace coumarin anticoagulants from binding sites. PT/INR should be closely monitored in patients concomitantly receiving coumarin anticoagulants and CASODEX. Adjustment of the anticoagulant dose may be necessary [see Warnings and Precautions (5.2) and Adverse Reactions (6.2)]. R-bicalutamide is an inhibitor of CYP 3A4; therefore, caution should be used when CASODEX is co-administered with CYP 3A4 substrates. (7) PT/INR should be closely monitored in patients already receiving coumarin anticoagulants who are started on CASODEX. (7)

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. 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 concentrations*) and uterine adenocarcinoma in female rats at 75 mg/kg/day (approximately 1 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. A small increase in the incidence of hepatocellular carcinoma in male mice given 75 mg/kg/day of bicalutamide (approximately 4 times human therapeutic concentrations*) and an increased incidence of benign thyroid follicular cell adenomas in rats given 5 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. 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 CASODEX does not have genotoxic activity. Administration of CASODEX may lead to inhibition of spermatogenesis. The long-term effects of CASODEX on male fertility have not been studied. In male rats dosed at 250 mg/kg/day (approximately 2 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 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, 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 a maximum dose of 50 mg/day of bicalutamide for an average 70-kg patient

USE IN SPECIFIC POPULATIONS SECTION.


8. USE IN SPECIFIC POPULATIONS Females and Males of Reproductive Potential: Advise males with female partners of reproductive potential to use effective contraception. (8.3) Pediatric patients: Efficacy has not been demonstrated for the treatment of familial male-limited precocious puberty (testotoxicosis). (8.4) 8.1. Pregnancy Risk Summary CASODEX is contraindicated for use in pregnant women because it can cause fetal harm. CASODEX is not indicated for use in females. There are no human data on the use of CASODEX in pregnant women. In animal reproduction studies, oral administration of bicalutamide to pregnant rats during organogenesis caused abnormal development of reproductive organs in male fetuses at exposures approximately 0.7 to 2 times the human exposure at the recommended dose (see Data). Data Animal Data In an embryo-fetal development study in pregnant rats dosed during the period of organogenesis from gestation days 6-15, male fetuses had reduced anogenital distance at doses of 10 mg/kg/day and above (approximately 0.7 to 2 times the human exposure at the recommended dose). In a pre- and post-natal development study, female rats were dosed from gestation day 7-16 and allowed to litter and rear their offspring to weaning. Male offspring of rats receiving doses of 10 mg/kg/day (approximately 0.7 times the human exposure at the recommended dose) and above, were observed to have reduced anogenital distance. In a peri- and post-natal development study, female rats were dosed from gestation day 16 to lactation day 22 and allowed to litter and rear their offspring to weaning. Survival and weights of offspring during lactation were reduced for litters from maternal rats receiving doses of 250 mg/kg/day (approximately 2 times the human exposure at the recommended dose). Male offspring of rats receiving doses of 10 mg/kg/day (approximately 0.7 times the human exposure at the recommended dose) and above, were observed to have reduced anogenital distance, smaller secondary sex organs, cryptorchidism and hypospadias resulting in an inability to mate and impregnate their female partners. Female offspring of rats receiving doses of 10 mg/kg/day (approximately 0.7 times the human exposure at the recommended dose) and above had reduced pregnancy rates. 8.2 Lactation Risk Summary CASODEX is not indicated for use in pregnant women. There is no information available on the presence of bicalutamide in human milk, or on the effects on the breastfed infant or on milk production. Bicalutamide has been detected in rat milk. 8.3 Females and Males of Reproductive Potential Contraception Males Antiandrogen therapy may cause morphological changes in spermatozoa [see Nonclinical Toxicology (13.1)]. Based on findings in animal reproduction studies and its mechanism of action, advise male patients with female partners of reproductive potential to use effective contraception during treatment and for 130 days after the final dose of CASODEX [see Use in Specific Populations (8.1) and Clinical Pharmacology (12.1)]. Infertility Males Based on animal studies, CASODEX can lead to inhibition of spermatogenesis and may impair fertility in males of reproductive potential. The long-term effects of CASODEX on male fertility have not been studied [see Nonclinical Toxicology (13.1)]. 8.4. Pediatric Use The safety and effectiveness of CASODEX in pediatric patients have not been established. CASODEX (bicalutamide) orodispersible tablet was studied in combination with ARIMIDEX (anastrozole) orodispersible tablet in an open-label, non-comparative, multi-center study that assessed the efficacy and safety of this combination regimen over 12 months in the treatment of gonadotropin-independent precocious puberty in boys with familial male-limited precocious puberty, also known as testotoxicosis. Patients were enrolled in the study if they had a baseline age 2 years and a diagnosis of testotoxicosis based on clinical features of progressive precocious puberty, symmetrical testicular enlargement, advanced bone age, pubertal levels of serum testosterone, prepubertal pattern of gonadotropin secretion following a GnRH stimulation test, and absence of other clinical and biochemical causes of testosterone excess. Thirteen out of the 14 patients enrolled completed 12 months of combination treatment (one patient was lost to follow-up). If central precocious puberty (CPP) developed an LHRH analog was to be added. Four patients were diagnosed with CPP during the 12-month study and received LHRH analog treatment and 2 additional patients were diagnosed at the end of the 12 months and received treatment subsequently. Mean SD characteristics at baseline were as follows: chronological age: 3.91.9 years; bone age 8.82.5; bone age/chronological age ratio: 2.060.51; growth rate (cm/yr): 10.814.22; growth rate standard deviation score (SDS): 0.411.36. The starting CASODEX dose was 12.5 mg. CASODEX was titrated in each patient until steady-state R-bicalutamide (the active isomer of bicalutamide) trough plasma concentration reached 5-15 mcg/mL, which is the range of therapeutic concentrations achieved in adults with prostate cancer following the administration of the currently approved CASODEX dose of 50 mg. The starting daily dose of anastrozole was 0.5 mg. Anastrozole was independently titrated in each patient until it reached at steady-state a serum estradiol concentration of 3 patients) adverse events were gynecomastia (7/14, 50%), central precocious puberty (6/14, 43%), vomiting (5/14, 36%), headache (3/14, 21%), pyrexia (3/14, 21%), and upper respiratory tract infection (3/14, 21%). Adverse reactions considered possibly related to bicalutamide by investigators included gynecomastia (6/14, 43%), central precocious puberty (2/14, 14%), breast tenderness (2/14, 14%), breast pain (1/14, 7%), asthenia (1/14, 7%), increased alanine aminotransferase [ALT] (1/14, 7%), increased aspartate aminotransferase [AST] (1/14, 7%), and musculoskeletal chest pain (1/14, 7%). Headache was the only adverse reaction considered possibly related to anastrozole by investigators. For the patient who developed elevated ALT and AST, the elevation was <3X ULN, and returned to normal without stopping treatment; there was no concomitant elevation in total bilirubin. 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 CASODEX should be used with caution in patients with moderate-to-severe hepatic impairment. CASODEX is extensively metabolized by the liver. Limited data in subjects with severe hepatic impairment suggest that excretion of CASODEX 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.

CASODEX is not for use by women. pregnant or may become pregnant. CASODEX may harm your unborn baby. Before taking CASODEX, tell your healthcare provider about all your medical conditions, including if you: have liver problems. take a medicine to thin your blood. Ask your healthcare provider or pharmacist if you are not sure if your medicine is a blood thinner. have diabetes. have a female partner who can become pregnant. Males who have a female partner who can become pregnant should use effective birth control during treatment with CASODEX and for 130 days after the final dose. Talk to your healthcare provider if you have any questions about birth control. Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. CASODEX may affect the way other medicines work and other medicines may affect how CASODEX works, causing side effects. Know the medicines you take. Keep a list of your medicines with you to show your healthcare providers when you get a new medicine. How should I take CASODEX? Take CASODEX exactly as your healthcare provider tells you to take it. Do not stop taking CASODEX unless your healthcare provider tells you to. CASODEX can be taken either in the morning or in the evening, but you should take it at the same time every day. Your treatment with CASODEX should start at the same time as your treatment with the LHRH medicine. If you miss a CASODEX dose do not take the missed dose, take the next dose at your next scheduled time. Do not take 2 doses at the same time. CASODEX can be taken with or without food. If you take too much CASODEX, call your healthcare provider or go to the nearest hospital emergency room right away. What should I avoid during treatment with CASODEX? Do not drive, operate machinery, or do other dangerous activities until you know how CASODEX affects you. Avoid sunlight, sunlamps, and tanning beds, and consider using sunscreen during treatment with CASODEX. Some people have had skin sensitivity to sunlight during treatment with CASODEX. What are the possible side effects of CASODEX? CASODEX may cause serious side effects, including: Liver problems. Severe liver problems, including liver failure that may need to be treated in a hospital or that may lead to death have happened in people who take CASODEX. Your healthcare provider should do blood tests to check your liver function before and during treatment with CASODEX. Tell your healthcare provider right away if you develop any of these symptoms of liver problems during treatment: oyellowing of the skin and eyes (jaundice) odark urine oright upper stomach pain onausea ovomiting otiredness oloss of appetite ochills ofever Bleeding problems. Serious bleeding problems have happened in people who take CASODEX in combination with a blood thinner medicine (coumarin anticoagulants). Bleeding problems have happened days to weeks after starting CASODEX treatment. If you take a blood thinner medicine during treatment with CASODEX, tell your healthcare provider if you develop any bleeding or unexplained bruising. Breast enlargement (gynecomastia) and breast pain. Blood sugar problems. Poor blood sugar control can happen in people who take CASODEX in combination with LHRH medicines. Your healthcare provider may do blood tests during treatment with CASODEX in combination with LHRH medicines. Your prostate cancer may get worse during treatment with CASODEX in combination with LHRH medicines. Regular monitoring of your prostate cancer with your healthcare provider is important to determine if your disease is worse. Tell your healthcare provider if you have trouble breathing with or without a cough or fever. Some people taking CASODEX get an inflammation in the lungs called interstitial lung disease. The most common side effects of CASODEX include: ohot flashes (short periods of feeling warm and sweating) obody pain (including back, pelvis, stomach) ofeeling weak oconstipation oinfection onausea oswelling in your arms, ankles, legs or feet oshortness of breath (dyspnea) odizziness odiarrhea oblood in your urine ofrequent urination at night oa decrease in red blood cells (anemia) CASODEX may have an effect on male fertility which could be reversible. Talk to your healthcare provider if this is a concern for you. Tell your healthcare provider if you have any side effect that bothers you or that does not go away. These are not all the possible side effects of CASODEX. For more information, ask your healthcare provider or pharmacist. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088. How should I store CASODEX? Store CASODEX at room temperature between 68F to 77F (20C to 25C).

CLINICAL STUDIES SECTION.


14. CLINICAL STUDIES 14.1. CASODEX 50 mg Daily in Combination with an LHRH-A In a multi-center, double-blind, controlled clinical trial, 813 patients with previously untreated advanced prostate cancer were randomized to receive CASODEX 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 CASODEX-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. 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 CASODEX 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. 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 CASODEX 150 mg CASODEX 150 mg is not approved for use either alone or with other treatments. Two identical multi-center, randomized, open-label trials comparing CASODEX 150 mg daily monotherapy to castration were conducted in patients that had locally advanced (T3-4, NX, M0) or metastatic (M1) prostate cancer. Monotherapy M1 Group CASODEX 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 CASODEX 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 CASODEX treated group compared to that in the castrated group, respectively. Locally Advanced (T3-4, NX, M0) Group CASODEX 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, M0 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 CASODEX 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 CASODEX group. In addition to the above two studies, there are three other ongoing clinical studies that provide additional safety information for CASODEX 150 mg, a dose that is not approved for use. These are three multi-center, randomized, double-blind, parallel group trials comparing CASODEX 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. CASODEX 150 mg daily is 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 CASODEX arm after a median follow-up of 7.4 years. There were 294 (37.7%) deaths in the CASODEX 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).

CLINICAL PHARMACOLOGY SECTION.


12. CLINICAL PHARMACOLOGY 12.1. Mechanism of Action CASODEX is 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 CASODEX is combined with LHRH analog therapy, the suppression of serum testosterone induced by the LHRH analog is not affected. However, in clinical trials with CASODEX 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 CASODEX and an LHRH agonist, and who discontinue CASODEX 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 CASODEX in normal males and patients with prostate cancer are presented in Table 3. Table 3.
