PROPECIA (finasteride) Tablets

FULL PRESCRIBING INFORMATION
1
INDICATIONS AND USAGE
PROPECIA® is indicated for the treatment of male pattern hair loss (androgenetic alopecia) in MEN ONLY.
Efficacy in bitemporal recession has not been established.
PROPECIA is not indicated for use in women.
2
DOSAGE AND ADMINISTRATIONPROPECIA may be administered with or without meals.
The recommended dose of PROPECIA is one tablet (1 mg) taken once daily.
In general, daily use for three months or more is necessary before benefit is observed. Continued use isrecommended to sustain benefit, which should be re-evaluated periodically. Withdrawal of treatment leads toreversal of effect within 12 months.
3
DOSAGE FORMS AND STRENGTHSPROPECIA tablets (1 mg) are tan, octagonal, film-coated convex tablets with “stylized P” logo on one side and
PROPECIA on the other.
4
CONTRAINDICATIONSPROPECIA is contraindicated in the following: Pregnancy. Finasteride use is contraindicated in women when they are or may potentially be pregnant. Becauseof the ability of Type II 5-reductase inhibitors to inhibit the conversion of testosterone to
5α-dihydrotestosterone (DHT), finasteride may cause abnormalities of the external genitalia of a male fetus of apregnant woman who receives finasteride. If this drug is used during pregnancy, or if pregnancy occurs while
taking this drug, the pregnant woman should be apprised of the potential hazard to the male fetus. [SeeWarnings and Precautions (5.1), Use in Specific Populations (8.1), How Supplied/Storage and Handling (16)and Patient Counseling Information (17.1).] In female rats, low doses of finasteride administered during
pregnancy have produced abnormalities of the external genitalia in male offspring.
 Hypersensitivity to any component of this medication.
5
WARNINGS AND PRECAUTIONS
5.1
Exposure of Women — Risk to Male Fetus
PROPECIA is not indicated for use in women. Women should not handle crushed or broken PROPECIA tablets
when they are pregnant or may potentially be pregnant because of the possibility of absorption of finasteride and thesubsequent potential risk to a male fetus. PROPECIA tablets are coated and will prevent contact with the active
ingredient during normal handling, provided that the tablets have not been broken or crushed. [See Indications andUsage (1), Contraindications (4), Use in Specific Populations (8.1), How Supplied/Storage and Handling (16) andPatient Counseling Information (17.1).]
5.2
Effects on Prostate Specific Antigen (PSA)
In clinical studies with PROPECIA (finasteride, 1 mg) in men 18-41 years of age, the mean value of serum prostate
specific antigen (PSA) decreased from 0.7 ng/mL at baseline to 0.5 ng/mL at Month 12. Further, in clinical studies
with PROSCAR (finasteride, 5 mg) when used in older men who have benign prostatic hyperplasia (BPH), PSA
levels are decreased by approximately 50%. Other studies with PROSCAR showed it may also cause decreases inserum PSA in the presence of prostate cancer. These findings should be taken into account for proper interpretationof serum PSA when evaluating men treated with finasteride. Any confirmed increase from the lowest PSA value
while on PROPECIA may signal the presence of prostate cancer and should be evaluated, even if PSA levels arestill within the normal range for men not taking a 5α-reductase inhibitor. Non-compliance to therapy withPROPECIA may also affect PSA test results.

Reference ID: 3114736

PROPECIA (finasteride) Tablets
5.3
Increased Risk of High-Grade Prostate Cancer with 5α-Reductase Inhibitors
Men aged 55 and over with a normal digital rectal examination and PSA ≤3.0 ng/mL at baseline taking finasteride 5
mg/day (5 times the dose of PROPECIA) in the 7-year Prostate Cancer Prevention Trial (PCPT) had an increased
risk of Gleason score 8-10 prostate cancer (finasteride 1.8% vs placebo 1.1%). [See Adverse Reactions (6.1).]
Similar results were observed in a 4-year placebo-controlled clinical trial with another 5α-reductase inhibitor(dutasteride, AVODART) (1% dutasteride vs 0.5% placebo). 5α-reductase inhibitors may increase the risk ofdevelopment of high-grade prostate cancer. Whether the effect of 5α-reductase inhibitors to reduce prostate volume,or study-related factors, impacted the results of these studies has not been established.
5.4
Pediatric Patients
PROPECIA is not indicated for use in pediatric patients [see Use in Specific Populations (8.4)].
6
ADVERSE REACTIONS
6.1
Clinical Trials Experience
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 clinical practice.
Clinical Studies for PROPECIA (finasteride 1 mg) in the Treatment of Male Pattern Hair Loss
In three controlled clinical trials for PROPECIA of 12-month duration, 1.4% of patients taking PROPECIA (n=945)
were discontinued due to adverse experiences that were considered to be possibly, probably or definitely drugrelated (1.6% for placebo; n=934).
Clinical adverse experiences that were reported as possibly, probably or definitely drug-related in ≥1% of patientstreated with PROPECIA or placebo are presented in Table 1.

Integrated analysis of clinical adverse experiences showed that during treatment with PROPECIA, 36 (3.8%) of 945
men had reported one or more of these adverse experiences as compared to 20 (2.1%) of 934 men treated withplacebo (p=0.04). Resolution occurred in men who discontinued therapy with PROPECIA due to these side effects
and in most of those who continued therapy. The incidence of each of the above adverse experiences decreased to≤0.3% by the fifth year of treatment with PROPECIA.
In a study of finasteride 1 mg daily in healthy men, a median decrease in ejaculate volume of 0.3 mL (-11%)
compared with 0.2 mL (-8%) for placebo was observed after 48 weeks of treatment. Two other studies showed thatfinasteride at 5 times the dosage of PROPECIA (5 mg daily) produced significant median decreases ofapproximately 0.5 mL (-25%) compared to placebo in ejaculate volume, but this was reversible after discontinuationof treatment.
In the clinical studies with PROPECIA, the incidences for breast tenderness and enlargement, hypersensitivity
reactions, and testicular pain in finasteride-treated patients were not different from those in patients treated withplacebo.

PROPECIA (finasteride) Tablets
Controlled Clinical Trials and Long-Term Open Extension Studies for PROSCAR® (finasteride 5 mg) and
AVODART (dutasteride) in the Treatment of Benign Prostatic Hyperplasia
In the PROSCAR Long-Term Efficacy and Safety Study (PLESS), a 4-year controlled clinical study, 3040 patients
between the ages of 45 and 78 with symptomatic BPH and an enlarged prostate were evaluated for safety over a
period of 4 years (1524 on PROSCAR 5 mg/day and 1516 on placebo). 3.7% (57 patients) treated with PROSCAR
5 mg and 2.1% (32 patients) treated with placebo discontinued therapy as a result of adverse reactions related tosexual function, which are the most frequently reported adverse reactions.
Table 2 presents the only clinical adverse reactions considered possibly, probably or definitely drug related by theinvestigator, for which the incidence on PROSCAR was ≥1% and greater than placebo over the 4 years of the study.
In years 2-4 of the study, there was no significant difference between treatment groups in the incidences ofimpotence, decreased libido and ejaculation disorder.

The adverse experience profiles in the 1-year, placebo-controlled, Phase III BPH studies and the 5-year open
extensions with PROSCAR 5 mg and PLESS were similar.
There is no evidence of increased sexual adverse experiences with increased duration of treatment with PROSCAR
5 mg. New reports of drug-related sexual adverse experiences decreased with duration of therapy.
During the 4- to 6-year placebo- and comparator-controlled Medical Therapy of Prostatic Symptoms (MTOPS)
study that enrolled 3047 men, there were 4 cases of breast cancer in men treated with PROSCAR but no cases inmen not treated with PROSCAR. During the 4-year placebo-controlled PLESS study that enrolled 3040 men, there
were 2 cases of breast cancer in placebo-treated men, but no cases were reported in men treated with PROSCAR.
During the 7-year placebo-controlled Prostate Cancer Prevention Trial (PCPT) that enrolled 18,882 men, there was
1 case of breast cancer in men treated with PROSCAR, and 1 case of breast cancer in men treated with placebo. The
relationship between long-term use of finasteride and male breast neoplasia is currently unknown.
The PCPT trial was a 7-year randomized, double-blind, placebo-controlled trial that enrolled 18,882 healthy men≥55 years of age with a normal digital rectal examination and a PSA ≤3.0 ng/mL. Men received either PROSCAR(finasteride 5 mg) or placebo daily. Patients were evaluated annually with PSA and digital rectal exams. Biopsies
were performed for elevated PSA, an abnormal digital rectal exam, or the end of study. The incidence of Gleason
score 8-10 prostate cancer was higher in men treated with finasteride (1.8%) than in those treated with placebo

Reference ID: 3114736

PROPECIA (finasteride) Tablets(1.1%). In a 4-year placebo-controlled clinical trial with another 5α-reductase inhibitor [AVODART (dutasteride)],similar results for Gleason score 8-10 prostate cancer were observed (1% dutasteride vs 0.5% placebo). The clinicalsignificance of these findings with respect to use of PROPECIA by men is unknown.
No clinical benefit has been demonstrated in patients with prostate cancer treated with PROSCAR. PROSCAR is
not approved to reduce the risk of developing prostate cancer.
6.2
Postmarketing Experience
The following adverse reactions have been identified during post approval use of PROPECIA. Because thesereactions 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:
Hypersensitivity Reaction: hypersensitivity reactions including rash, pruritus, urticaria, and swelling of the lips andface;
Reproductive System: sexual dysfunction that continued after discontinuation of treatment, including erectile
dysfunction, libido disorders, ejaculation disorders, and orgasm disorders; male infertility and/or poor seminal
quality (normalization or improvement of seminal quality has been reported after discontinuation of finasteride);
testicular pain. [See Adverse Reactions (6.1).]
Neoplasms: male breast cancer;
Breast disorders: breast tenderness and enlargement;
Nervous System/Psychiatric: depression

DRUG INTERACTIONS
7.1
Cytochrome P450-Linked Drug Metabolizing Enzyme System
No drug interactions of clinical importance have been identified. Finasteride does not appear to affect thecytochrome P450-linked drug-metabolizing enzyme system. Compounds that have been tested in man include
antipyrine, digoxin, propranolol, theophylline, and warfarin and no clinically meaningful interactions were found.
7.2
Other Concomitant Therapy
Although specific interaction studies were not performed, finasteride doses of 1 mg or more were concomitantly
used in clinical studies with acetaminophen, acetylsalicylic acid, -blockers, analgesics, angiotensin-converting
enzyme (ACE) inhibitors, anticonvulsants, benzodiazepines, beta blockers, calcium-channel blockers, cardiac
nitrates, diuretics, H2 antagonists, HMG-CoA reductase inhibitors, prostaglandin synthetase inhibitors (also referred
to as NSAIDs), and quinolone anti-infectives without evidence of clinically significant adverse interactions.

USE IN SPECIFIC POPULATIONS
8.1
Pregnancy
Pregnancy Category X [see Contraindications (4)].
PROPECIA is contraindicated for use in women who are or may become pregnant. PROPECIA is a Type II
5α-reductase inhibitor that prevents conversion of testosterone to 5α-dihydrotestosterone (DHT), a hormone
necessary for normal development of male genitalia. In animal studies, finasteride caused abnormal development of
external genitalia in male fetuses. 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 the male fetus.
Abnormal male genital development is an expected consequence when conversion of testosterone to 5α­dihydrotestosterone (DHT) is inhibited by 5α-reductase inhibitors. These outcomes are similar to those reported inmale infants with genetic 5α-reductase deficiency. Women could be exposed to finasteride through contact withcrushed or broken PROPECIA tablets or semen from a male partner taking PROPECIA. With regard to finasteride
exposure through the skin, PROPECIA tablets are coated and will prevent skin contact with finasteride during
normal handling if the tablets have not been crushed or broken. Women who are pregnant or may become pregnant

Reference ID: 3114736

PROPECIA (finasteride) Tablets
should not handle crushed or broken PROPECIA tablets because of possible exposure of a male fetus. If a pregnant
woman comes in contact with crushed or broken PROPECIA tablets, the contact area should be washedimmediately with soap and water. With regard to potential finasteride exposure through semen, a study has been
conducted in men receiving PROPECIA 1 mg/day that measured finasteride concentrations in semen [see ClinicalPharmacology (12.3)].
In an embryo-fetal development study, pregnant rats received finasteride during the period of major organogenesis(gestation days 6 to 17). At maternal doses of oral finasteride approximately 1 to 684 times the recommended
human dose (RHD) of 1 mg/day (based on AUC at animal doses of 0.1 to 100 mg/kg/day) there was a dosedependent increase in hypospadias that occurred in 3.6 to 100% of male offspring. Exposure multiples were
estimated using data from nonpregnant rats. Days 16 to 17 of gestation is a critical period in male fetal rats fordifferentiation of the external genitalia. At oral maternal doses approximately 0.2 times the RHD (based on AUC atanimal dose of 0.03 mg/kg/day), male offspring had decreased prostatic and seminal vesicular weights, delayed
preputial separation and transient nipple development. Decreased anogenital distance occurred in male offspring ofpregnant rats that received approximately 0.02 times the RHD (based on AUC at animal dose of 0.003 mg/kg/day).
No abnormalities were observed in female offspring exposed to any dose of finasteride in utero.
No developmental abnormalities were observed in the offspring of untreated females mated with finasteride-treatedmale rats that received approximately 488 times the RHD (based on AUC at animal dose of 80 mg/kg/day). Slightly
decreased fertility was observed in male offspring after administration of about 20 times the RHD (based on AUC atanimal dose of 3 mg/kg/day) to female rats during late gestation and lactation. No effects on fertility were seen infemale offspring under these conditions.
No evidence of male external genital malformations or other abnormalities were observed in rabbit fetuses exposed
to finasteride during the period of major organogenesis (gestation days 6-18) at maternal doses up to 100 mg/kg/day(finasteride exposure levels were not measured in rabbits). However, this study may not have included the critical
period for finasteride effects on development of male external genitalia in the rabbit.
The fetal effects of maternal finasteride exposure during the period of embryonic and fetal development were
evaluated in the rhesus monkey (gestation days 20-100), in a species and development period more predictive ofspecific effects in humans than the studies in rats and rabbits. Intravenous administration of finasteride to pregnant
monkeys at doses as high as 800 ng/day (estimated maximal blood concentration of 1.86 ng/mL or about 930 times
the highest estimated exposure of pregnant women to finasteride from semen of men taking 1 mg/day) resulted in noabnormalities in male fetuses. In confirmation of the relevance of the rhesus model for human fetal development,
oral administration of a dose of finasteride (2 mg/kg/day or approximately 120,000 times the highest estimatedblood levels of finasteride from semen of men taking 1 mg/day) to pregnant monkeys resulted in external genitalabnormalities in male fetuses. No other abnormalities were observed in male fetuses and no finasteride-related
abnormalities were observed in female fetuses at any dose.
8.3 Nursing Mothers
PROPECIA is not indicated for use in women.
It is not known whether finasteride is excreted in human milk.
8.4 Pediatric Use
PROPECIA is not indicated for use in pediatric patients.
Safety and effectiveness in pediatric patients have not been established.
8.5 Geriatric Use
Clinical efficacy studies with PROPECIA did not include subjects aged 65 and over. Based on the pharmacokinetics
of finasteride 5 mg, no dosage adjustment is necessary in the elderly for PROPECIA [see Clinical Pharmacology(12.3)]. However the efficacy of PROPECIA in the elderly has not been established.

Reference ID: 3114736

PROPECIA (finasteride) Tablets
8.6 Hepatic Impairment
Caution should be exercised in the administration of PROPECIA in those patients with liver function abnormalities,
as finasteride is metabolized extensively in the liver [see Clinical Pharmacology (12.3)].
8.7 Renal Impairment
No dosage adjustment is necessary in patients with renal impairment [see Clinical Pharmacology (12.3)].
10
OVERDOSAGEIn clinical studies, single doses of finasteride up to 400 mg and multiple doses of finasteride up to 80 mg/day forthree months did not result in adverse reactions. Until further experience is obtained, no specific treatment for an
overdose with finasteride can be recommended.
Significant lethality was observed in male and female mice at single oral doses of 1500 mg/m2 (500 mg/kg) and infemale and male rats at single oral doses of 2360 mg/m2 (400 mg/kg) and 5900 mg/m2 (1000 mg/kg), respectively.
11
DESCRIPTIONPROPECIA (finasteride) tablets contain finasteride as the active ingredient. Finasteride, a synthetic 4-azasteroid
compound, is a specific inhibitor of steroid Type II 5-reductase, an intracellular enzyme that converts the androgen
testosterone into 5-dihydrotestosterone (DHT).
The chemical name of finasteride is N-tert-Butyl-3-oxo-4-aza-5-androst-1-ene-17-carboxamide. The empiricalformula of finasteride is C23H36N2O2 and its molecular weight is 372.55. Its structural formula is:

Finasteride is a white crystalline powder with a melting point near 250°C. It is freely soluble in chloroform and inlower alcohol solvents but is practically insoluble in water.
PROPECIA (finasteride) tablets are film-coated tablets for oral administration. Each tablet contains 1 mg offinasteride and the following inactive ingredients: lactose monohydrate, microcrystalline cellulose, pregelatinizedstarch, sodium starch glycolate, hydroxypropyl methylcellulose, hydroxypropyl cellulose, titanium dioxide,
magnesium stearate, talc, docusate sodium, yellow ferric oxide, and red ferric oxide.
12
CLINICAL PHARMACOLOGY
12.1 Mechanism of Action
Finasteride is a competitive and specific inhibitor of Type II 5-reductase, an intracellular enzyme that converts theandrogen testosterone into DHT. Two distinct isozymes are found in mice, rats, monkeys, and humans: Type I and
II. Each of these isozymes is differentially expressed in tissues and developmental stages. In humans, Type I 5­
reductase is predominant in the sebaceous glands of most regions of skin, including scalp, and liver. Type I 5­
reductase is responsible for approximately one-third of circulating DHT. The Type II 5-reductase isozyme is
primarily found in prostate, seminal vesicles, epididymides, and hair follicles as well as liver, and is responsible for
two-thirds of circulating DHT.

Reference ID: 3114736

PROPECIA (finasteride) Tablets
In humans, the mechanism of action of finasteride is based on its preferential inhibition of the Type II isozyme.
Using native tissues (scalp and prostate), in vitro binding studies examining the potential of finasteride to inhibit
either isozyme revealed a 100-fold selectivity for the human Type II 5-reductase over Type I isozyme (IC50=500
and 4.2 nM for Type I and II, respectively). For both isozymes, the inhibition by finasteride is accompanied by
reduction of the inhibitor to dihydrofinasteride and adduct formation with NADP+. The turnover for the enzyme
complex is slow (t1/2 approximately 30 days for the Type II enzyme complex and 14 days for the Type I complex).
Inhibition of Type II 5-reductase blocks the peripheral conversion of testosterone to DHT, resulting in significant
decreases in serum and tissue DHT concentrations.
In men with male pattern hair loss (androgenetic alopecia), the balding scalp contains miniaturized hair follicles andincreased amounts of DHT compared with hairy scalp. Administration of finasteride decreases scalp and serum
DHT concentrations in these men. The relative contributions of these reductions to the treatment effect offinasteride have not been defined. By this mechanism, finasteride appears to interrupt a key factor in thedevelopment of androgenetic alopecia in those patients genetically predisposed.
12.2 Pharmacodynamics
Finasteride produces a rapid reduction in serum DHT concentration, reaching 65% suppression within 24 hours oforal dosing with a 1-mg tablet. Mean circulating levels of testosterone and estradiol were increased byapproximately 15% as compared to baseline, but these remained within the physiologic range.
Finasteride has no affinity for the androgen receptor and has no androgenic, antiandrogenic, estrogenic,
antiestrogenic, or progestational effects. In studies with finasteride, no clinically meaningful changes in luteinizing
hormone (LH), follicle-stimulating hormone (FSH) or prolactin were detected. In healthy volunteers, treatment withfinasteride did not alter the response of LH and FSH to gonadotropin-releasing hormone indicating that the
hypothalamic-pituitary-testicular axis was not affected. Finasteride had no effect on circulating levels of cortisol,
thyroid-stimulating hormone, or thyroxine, nor did it affect the plasma lipid profile (e.g., total cholesterol, lowdensity lipoproteins, high-density lipoproteins and triglycerides) or bone mineral density.
12.3
Pharmacokinetics
Absorption
In a study in 15 healthy young male subjects, the mean bioavailability of finasteride 1-mg tablets was 65% (range
26-170%), based on the ratio of area under the curve (AUC) relative to an intravenous (IV) reference dose. At
steady state following dosing with 1 mg/day (n=12), maximum finasteride plasma concentration averaged
9.2 ng/mL (range, 4.9-13.7 ng/mL) and was reached 1 to 2 hours postdose; AUC(0-24 hr) was 53 ng•hr/mL (range,
20-154 ng•hr/mL). Bioavailability of finasteride was not affected by food.
Distribution
Mean steady-state volume of distribution was 76 liters (range, 44-96 liters; n=15). Approximately 90% of
circulating finasteride is bound to plasma proteins. There is a slow accumulation phase for finasteride after multiple
dosing.
Finasteride has been found to cross the blood-brain barrier.
Semen levels have been measured in 35 men taking finasteride 1 mg/day for 6 weeks. In 60% (21 of 35) of thesamples, finasteride levels were undetectable (<0.2 ng/mL). The mean finasteride level was 0.26 ng/mL and thehighest level measured was 1.52 ng/mL. Using the highest semen level measured and assuming 100% absorption
from a 5-mL ejaculate per day, human exposure through vaginal absorption would be up to 7.6 ng per day, which is
650-fold less than the dose of finasteride (5 g) that had no effect on circulating DHT levels in men. [See Use inSpecific Populations (8.1).]
Metabolism
Finasteride is extensively metabolized in the liver, primarily via the cytochrome P450 3A4 enzyme subfamily. Twometabolites, the t-butyl side chain monohydroxylated and monocarboxylic acid metabolites, have been identified
that possess no more than 20% of the 5-reductase inhibitory activity of finasteride.

Reference ID: 3114736

PROPECIA (finasteride) Tablets

Excretion
Following intravenous infusion in healthy young subjects (n=15), mean plasma clearance of finasteride was
165 mL/min (range, 70-279 mL/min). Mean terminal half-life in plasma was 4.5 hours (range, 3.3-13.4 hours;
n=12). Following an oral dose of 14C-finasteride in man (n=6), a mean of 39% (range, 32-46%) of the dose was
excreted in the urine in the form of metabolites; 57% (range, 51-64%) was excreted in the feces.
Mean terminal half-life is approximately 5-6 hours in men 18-60 years of age and 8 hours in men more than 70
years of age.

Renal Impairment
No dosage adjustment is necessary in patients with renal impairment. In patients with chronic renal impairment,with creatinine clearances ranging from 9.0 to 55 mL/min, AUC, maximum plasma concentration, half-life, andprotein binding after a single dose of 14C-finasteride were similar to those obtained in healthy volunteers. Urinary
excretion of metabolites was decreased in patients with renal impairment. This decrease was associated with anincrease in fecal excretion of metabolites. Plasma concentrations of metabolites were significantly higher in patientswith renal impairment (based on a 60% increase in total radioactivity AUC). However, finasteride has been
tolerated in men with normal renal function receiving up to 80 mg/day for 12 weeks where exposure of thesepatients to metabolites would presumably be much greater.
Hepatic Impairment
The effect of hepatic impairment on finasteride pharmacokinetics has not been studied. Caution should be used in
the administration of PROPECIA in patients with liver function abnormalities, as finasteride is metabolized
extensively in the liver.

NONCLINICAL TOXICOLOGY
13.1
Carcinogenesis, Mutagenesis, Impairment of Fertility
No evidence of a tumorigenic effect was observed in a 24-month study in Sprague-Dawley rats receiving doses offinasteride up to 160 mg/kg/day in males and 320 mg/kg/day in females. These doses produced respective systemic
exposure in rats of 888 and 2192 times those observed in man receiving the recommended human dose of 1 mg/day.
All exposure calculations were based on calculated AUC(0-24 hr) for animals and mean AUC(0-24 hr) for man(0.05 g•hr/mL).
In a 19-month carcinogenicity study in CD-1 mice, a statistically significant (p≤0.05) increase in the incidence oftesticular Leydig cell adenomas was observed at 1824 times the human exposure (250 mg/kg/day). In mice at 184

Reference ID: 3114736

PROPECIA (finasteride) Tablets
times the human exposure, estimated (25 mg/kg/day) and in rats at 312 times the human exposure (≥40 mg/kg/day)an increase in the incidence of Leydig cell hyperplasia was observed. A positive correlation between the
proliferative changes in the Leydig cells and an increase in serum LH levels (2- to 3-fold above control) has been
demonstrated in both rodent species treated with high doses of finasteride. No drug-related Leydig cell changes
were seen in either rats or dogs treated with finasteride for 1 year at 240 and 2800 times (20 mg/kg/day and 45
mg/kg/day, respectively), or in mice treated for 19 months at 18.4 times the human exposure, estimated (2.5mg/kg/day).
No evidence of mutagenicity was observed in an in vitro bacterial mutagenesis assay, a mammalian cell mutagenesis
assay, or in an in vitro alkaline elution assay. In an in vitro chromosome aberration assay, using Chinese hamster
ovary cells, there was a slight increase in chromosome aberrations. In an in vivo chromosome aberration assay inmice, no treatment-related increase in chromosome aberration was observed with finasteride at the maximum
tolerated dose of 250 mg/kg/day (1824 times the human exposure) as determined in the carcinogenicity studies.
In sexually mature male rabbits treated with finasteride at 4344 times the human exposure (80 mg/kg/day) for up to
12 weeks, no effect on fertility, sperm count, or ejaculate volume was seen. In sexually mature male rats treatedwith 488 times the human exposure (80 mg/kg/day), there were no significant effects on fertility after 6 or 12 weeks
of treatment; however, when treatment was continued for up to 24 or 30 weeks, there was an apparent decrease infertility, fecundity, and an associated significant decrease in the weights of the seminal vesicles and prostate. All
these effects were reversible within 6 weeks of discontinuation of treatment. No drug-related effect on testes or on
mating performance has been seen in rats or rabbits. This decrease in fertility in finasteride-treated rats is secondary
to its effect on accessory sex organs (prostate and seminal vesicles) resulting in failure to form a seminal plug. The
seminal plug is essential for normal fertility in rats but is not relevant in man.

CLINICAL STUDIES
14.1
Studies in Men
The efficacy of PROPECIA was demonstrated in men (88% Caucasian) with mild to moderate androgenetic
alopecia (male pattern hair loss) between 18 and 41 years of age. In order to prevent seborrheic dermatitis whichmight confound the assessment of hair growth in these studies, all men, whether treated with finasteride or placebo,were instructed to use a specified, medicated, tar-based shampoo (Neutrogena T/Gel® * Shampoo) during the first 2
years of the studies.
There were three double-blind, randomized, placebo-controlled studies of 12-month duration. The two primary
endpoints were hair count and patient self-assessment; the two secondary endpoints were investigator assessment
and ratings of photographs. In addition, information was collected regarding sexual function (based on a selfadministered questionnaire) and non-scalp body hair growth. The three studies were conducted in 1879 men withmild to moderate, but not complete, hair loss. Two of the studies enrolled men with predominantly mild to moderatevertex hair loss (n=1553). The third enrolled men having mild to moderate hair loss in the anterior mid-scalp areawith or without vertex balding (n=326).
Studies in Men with Vertex Baldness
Of the men who completed the first 12 months of the two vertex baldness trials, 1215 elected to continue in doubleblind, placebo-controlled, 12-month extension studies. There were 547 men receiving PROPECIA for both theinitial study and first extension periods (up to 2 years of treatment) and 60 men receiving placebo for the same
periods. The extension studies were continued for 3 additional years, with 323 men on PROPECIA and 23 onplacebo entering the fifth year of the study.
In order to evaluate the effect of discontinuation of therapy, there were 65 men who received PROPECIA for the
initial 12 months followed by placebo in the first 12-month extension period. Some of these men continued inadditional extension studies and were switched back to treatment with PROPECIA, with 32 men entering the fifth
year of the study. Lastly, there were 543 men who received placebo for the initial 12 months followed by
PROPECIA in the first 12-month extension period. Some of these men continued in additional extension studies
receiving PROPECIA, with 290 men entering the fifth year of the study (see Figure 1 below).

PROPECIA (finasteride) Tablets

Hair counts were assessed by photographic enlargements of a representative area of active hair loss. In these twostudies in men with vertex baldness, significant increases in hair count were demonstrated at 6 and 12 months inmen treated with PROPECIA, while significant hair loss from baseline was demonstrated in those treated withplacebo. At 12 months there was a 107-hair difference from placebo (p<0.001, PROPECIA [n=679] vs placebo[n=672]) within a 1-inch diameter circle (5.1 cm2). Hair count was maintained in those men taking PROPECIA for
up to 2 years, resulting in a 138-hair difference between treatment groups (p<0.001, PROPECIA [n=433] vs placebo[n=47]) within the same area. In men treated with PROPECIA, the maximum improvement in hair count compared
to baseline was achieved during the first 2 years. Although the initial improvement was followed by a slow decline,
hair count was maintained above baseline throughout the 5 years of the studies. Furthermore, because the decline in
the placebo group was more rapid, the difference between treatment groups also continued to increase throughout
the studies, resulting in a 277-hair difference (p<0.001, PROPECIA [n=219] vs placebo [n=15]) at 5 years (seeFigure 1 below).
Patients who switched from placebo to PROPECIA (n=425) had a decrease in hair count at the end of the initial 12­month placebo period, followed by an increase in hair count after 1 year of treatment with PROPECIA. This
increase in hair count was less (56 hairs above original baseline) than the increase (91 hairs above original baseline)
observed after 1 year of treatment in men initially randomized to PROPECIA. Although the increase in hair count,relative to when therapy was initiated, was comparable between these two groups, a higher absolute hair count wasachieved in patients who were started on treatment with PROPECIA in the initial study. This advantage wasmaintained through the remaining 3 years of the studies. A change of treatment from PROPECIA to placebo (n=48)
at the end of the initial 12 months resulted in reversal of the increase in hair count 12 months later, at 24 months(see Figure 1 below).
At 12 months, 58% of men in the placebo group had further hair loss (defined as any decrease in hair count frombaseline), compared with 14% of men treated with PROPECIA. In men treated for up to 2 years, 72% of men in theplacebo group demonstrated hair loss, compared with 17% of men treated with PROPECIA. At 5 years, 100% of
men in the placebo group demonstrated hair loss, compared with 35% of men treated with PROPECIA.

PROPECIA (finasteride) Tablets
Patient self-assessment was obtained at each clinic visit from a self-administered questionnaire, which included
questions on their perception of hair growth, hair loss, and appearance. This self-assessment demonstrated anincrease in amount of hair, a decrease in hair loss, and improvement in appearance in men treated with PROPECIA.
Overall improvement compared with placebo was seen as early as 3 months (p<0.05), with improvement maintained
over 5 years.
Investigator assessment was based on a 7-point scale evaluating increases or decreases in scalp hair at each patient
visit. This assessment showed significantly greater increases in hair growth in men treated with PROPECIA
compared with placebo as early as 3 months (p<0.001). At 12 months, the investigators rated 65% of men treatedwith PROPECIA as having increased hair growth compared with 37% in the placebo group. At 2 years, theinvestigators rated 80% of men treated with PROPECIA as having increased hair growth compared with 47% of
men treated with placebo. At 5 years, the investigators rated 77% of men treated with PROPECIA as having
increased hair growth, compared with 15% of men treated with placebo.
An independent panel rated standardized photographs of the head in a blinded fashion based on increases ordecreases in scalp hair using the same 7-point scale as the investigator assessment. At 12 months, 48% of men
treated with PROPECIA had an increase as compared with 7% of men treated with placebo. At 2 years, an increasein hair growth was demonstrated in 66% of men treated with PROPECIA, compared with 7% of men treated withplacebo. At 5 years, 48% of men treated with PROPECIA demonstrated an increase in hair growth, 42% were rated
as having no change (no further visible progression of hair loss from baseline) and 10% were rated as having losthair when compared to baseline. In comparison, 6% of men treated with placebo demonstrated an increase in hair
growth, 19% were rated as having no change and 75% were rated as having lost hair when compared to baseline.
A 48-week, placebo-controlled study designed to assess by phototrichogram the effect of PROPECIA on total andactively growing (anagen) scalp hairs in vertex baldness enrolled 212 men with androgenetic alopecia. At baseline
and 48 weeks, total and anagen hair counts were obtained in a 1-cm2 target area of the scalp. Men treated withPROPECIA showed increases from baseline in total and anagen hair counts of 7 hairs and 18 hairs, respectively,
whereas men treated with placebo had decreases of 10 hairs and 9 hairs, respectively. These changes in hair counts
resulted in a between-group difference of 17 hairs in total hair count (p<0.001) and 27 hairs in anagen hair count(p<0.001), and an improvement in the proportion of anagen hairs from 62% at baseline to 68% for men treated withPROPECIA.
Other Results in Vertex Baldness Studies
A sexual function questionnaire was self-administered by patients participating in the two vertex baldness trials to
detect more subtle changes in sexual function. At Month 12, statistically significant differences in favor of placebo
were found in 3 of 4 domains (sexual interest, erections, and perception of sexual problems). However, nosignificant difference was seen in the question on overall satisfaction with sex life.
In one of the two vertex baldness studies, patients were questioned on non-scalp body hair growth. PROPECIA did
not appear to affect non-scalp body hair.
Study in Men with Hair Loss in the Anterior Mid-Scalp Area
A study of 12-month duration, designed to assess the efficacy of PROPECIA in men with hair loss in the anterior
mid-scalp area, also demonstrated significant increases in hair count compared with placebo. Increases in hair countwere accompanied by improvements in patient self-assessment, investigator assessment, and ratings based onstandardized photographs. Hair counts were obtained in the anterior mid-scalp area, and did not include the area ofbitemporal recession or the anterior hairline.
Summary of Clinical Studies in Men
Clinical studies were conducted in men aged 18 to 41 with mild to moderate degrees of androgenetic alopecia. All
men treated with PROPECIA or placebo received a tar-based shampoo (Neutrogena T/Gel® Shampoo) during thefirst 2 years of the studies. Clinical improvement was seen as early as 3 months in the patients treated withPROPECIA and led to a net increase in scalp hair count and hair regrowth. In clinical studies for up to 5 years,
treatment with PROPECIA slowed the further progression of hair loss observed in the placebo group. In general, thedifference between treatment groups continued to increase throughout the 5 years of the studies.

Ethnic Analysis of Clinical Data from Men
In a combined analysis of the two studies on vertex baldness, mean hair count changes from baseline were 91 vs -19
hairs (PROPECIA vs placebo) among Caucasians (n=1185), 49 vs -27 hairs among Blacks (n=84), 53 vs -38 hairs
among Asians (n=17), 67 vs 5 hairs among Hispanics (n=45) and 67 vs -15 hairs among other ethnic groups (n=20).
Patient self-assessment showed improvement across racial groups with PROPECIA treatment, except forsatisfaction of the frontal hairline and vertex in Black men, who were satisfied overall.
14.2
Study in Women
In a study involving 137 postmenopausal women with androgenetic alopecia who were treated with PROPECIA(n=67) or placebo (n=70) for 12 months, effectiveness could not be demonstrated. There was no improvement inhair counts, patient self-assessment, investigator assessment, or ratings of standardized photographs in the women
treated with PROPECIA when compared with the placebo group [see Indications and Usage (1.1)].

17.1
Exposure of Women — Risk to Male Fetus
Physicians should inform patients that women who are pregnant or may potentially be pregnant should not handle
crushed or broken PROPECIA tablets because of the possibility of absorption of finasteride and the subsequentpotential risk to a male fetus. PROPECIA tablets are coated and will prevent contact with the active ingredientduring normal handling, provided that the tablets have not been broken or crushed. If a woman who is pregnant or
may potentially be pregnant comes in contact with crushed or broken PROPECIA tablets, the contact area should be
washed immediately with soap and water [see Contraindications (4), Warnings and Precautions (5.1), Use inSpecific Populations (8.1) and How Supplied/Storage and Handling (16)].
17.2
Increased Risk of High-Grade Prostate Cancer
Patients should be informed that there was an increase in high-grade prostate cancer in men treated with 5α­
reductase inhibitors indicated for BPH treatment, compared to those treated with placebo in studies looking at theuse of these drugs to prevent prostate cancer [see Warnings and Precautions (5.3) and Adverse Reactions (6.1)].
17.3
Additional Instructions
Physicians should instruct their patients to promptly report any changes in their breasts such as lumps, pain or
nipple discharge. Breast changes including breast enlargement, tenderness and neoplasm have been reported [seeAdverse Reactions (6.1)].
Physicians should instruct their patients to read the patient package insert before starting therapy with PROPECIA
and to read it again each time the prescription is renewed so that they are aware of current information for patients
regarding PROPECIA.

Patient Information
PROPECIA (Pro-pee-sha)(finasteride)
Tablets

PROPECIA is for use by MEN ONLY and should NOT be used by women or
children.
Read this Patient Information before you start taking PROPECIAand each time you
get a refill. There may be new information. This information does not take theplace of talking with your healthcare provider about your medical condition ortreatment.
What is PROPECIA?
PROPECIA is a prescription medicine used for the treatment of male pattern hairloss (androgenetic alopecia).
It is not known if PROPECIA works for a receding hairline on either side of andabove your forehead (temporal area).
PROPECIA is not for use by women and children.
Who should not take PROPECIA?
Do not take PROPECIA if you:

are pregnant or may become pregnant. PROPECIA may harm your unbornbaby.
oPROPECIA tablets are coated and will prevent contact with the
medicine during handling, as long as the tablets are not broken or
crushed. Females who are pregnant or who may become pregnant
should not come in contact with broken or crushed PROPECIA tablets.
If a pregnant woman comes in contact with crushed or broken
PROPECIA tablets, wash the contact area right away with soap andwater. If a woman who is pregnant comes into contact with the active
ingredient in PROPECIA, a healthcare provider should be consulted.

o

If a woman who is pregnant with a male baby swallows or comes incontact with the medicine in PROPECIA, the male baby may be bornwith sex organs that are not normal.

are allergic to any of the ingredients in PROPECIA. See the end of this leaflet

What should I tell my healthcare provider before taking PROPECIA?
Before taking PROPECIA, tell your healthcare provider if you:

have any other medical conditions, including problems with your prostate orliver

Tell your healthcare provider about all the medicines you take, including
prescription and non-prescription medicines, vitamins, and herbal supplements.
Know the medicines you take. Keep a list of them to show your healthcare provider
and pharmacist when you get a new medicine.
How should I take PROPECIA?
Take PROPECIA exactly as your healthcare provider tells you to take it.

You may take PROPECIA with or without food.

If you forget to take PROPECIA do not take an extra tablet. Just take thenext tablet as usual.

PROPECIA will not work faster or better if you take it more than once a day.

What are the possible side effects of PROPECIA?
 decrease in your blood Prostate Specific Antigen (PSA) levels.
PROPECIA can affect a blood test called PSA (Prostate Specific Antigen) for
the screening of prostate cancer. If you have a PSA test done you should tell
your healthcare provider that you are taking PROPECIA because PROPECIA
decreases PSA levels. Changes in PSA levels will need to be evaluated by yourhealthcare provider. Any increase in follow-up PSA levels from their lowest
point may signal the presence of prostate cancer and should be evaluated,even if the test results are still within the normal range for men not taking
PROPECIA. You should also tell your healthcare provider if you have not been
taking PROPECIA as prescribed because this may affect the PSA test results.
For more information, talk to your healthcare provider.


There may be an increased risk of a more serious form of prostate cancer in
men taking finasteride at 5 times the dose of PROPECIA.

The most common side effects of PROPECIA include: decrease in sex drive
