5 WARNINGS AND PRECAUTIONS
5.1 Effects on Prostate Specific Antigen (PSA) and the Use of PSA in Prostate Cancer Detection
In clinical studies, Tricoplus reduced serum PSA concentration by approximately 50% within six months of treatment. This decrease is predictable over the entire range of PSA values in patients with symptomatic BPH, although it may vary in individuals.
For interpretation of serial PSAs in men taking Tricoplus, a new PSA baseline should be established at least six months after starting treatment and PSA monitored periodically thereafter. Any confirmed increase from the lowest PSA value while on Tricoplus may signal the presence of prostate cancer and should be evaluated, even if PSA levels are still within the normal range for men not taking a 5α-reductase inhibitor. Non-compliance with Tricoplus therapy may also affect PSA test results. To interpret an isolated PSA value in patients treated with Tricoplus for six months or more, PSA values should be doubled for comparison with normal ranges in untreated men. These adjustments preserve the utility of PSA to detect prostate cancer in men treated with Tricoplus.
Tricoplus may also cause decreases in serum PSA in the presence of prostate cancer.
The ratio of free to total PSA (percent free PSA) remains constant even under the influence of Tricoplus. If clinicians elect to use percent free PSA as an aid in the detection of prostate cancer in men undergoing Tricoplus therapy, no adjustment to its value appears necessary.
5.2 Increased Risk of High-Grade Prostate Cancer
Men aged 55 and over with a normal digital rectal examination and PSA ≤3.0 ng/mL at baseline taking Tricoplus 5 mg/day in the 7-year Prostate Cancer Prevention Trial had an increased risk of Gleason score 8-10 prostate cancer (finasteride 1.8% vs placebo 1.1%). 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 of development 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.
5.3 Exposure of Women - Risk to Male Fetus
Women should not handle crushed or broken Tricoplus tablets when they are pregnant or may potentially be pregnant because of the possibility of absorption of Tricoplus and the subsequent potential risk to a male fetus. Tricoplus tablets are coated and will prevent contact with the active ingredient during normal handling, provided that the tablets have not been broken or crushed.
5.4 Pediatric Patients and Women
Tricoplus is not indicated for use in pediatric patients or women .
5.5 Effect on Semen Characteristics
Treatment with Tricoplus for 24 weeks to evaluate semen parameters in healthy male volunteers revealed no clinically meaningful effects on sperm concentration, mobility, morphology, or pH. A 0.6 mL (22.1%) median decrease in ejaculate volume with a concomitant reduction in total sperm per ejaculate was observed. These parameters remained within the normal range and were reversible upon discontinuation of therapy with an average time to return to baseline of 84 weeks.
5.6 Consideration of Other Urological Conditions
Prior to initiating treatment with Tricoplus, consideration should be given to other urological conditions that may cause similar symptoms. In addition, prostate cancer and BPH may coexist.
Patients with large residual urinary volume and/or severely diminished urinary flow should be carefully monitored for obstructive uropathy. These patients may not be candidates for Tricoplus therapy.
6 ADVERSE REACTIONS
The drug-related adverse reactions, reported in ≥1% in patients treated with Tricoplus and greater than in patients treated with placebo over a 4-year study are: impotence, decreased libido, decreased volume of ejaculate, breast enlargement, breast tenderness and rash.
To report SUSPECTED ADVERSE REACTIONS, contact Merck Sharp & Dohme Corp., a subsidiary of Merck & Co., Inc., at 1-877-888-4231 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch .
6.1 Clinical Trials Experience
Tricoplus is generally well tolerated; adverse reactions usually have been mild and transient.
4-Year Placebo-Controlled Study (PLESS)
In PLESS, 1524 patients treated with Tricoplus and 1516 patients treated with placebo were evaluated for safety over a period of 4 years. The most frequently reported adverse reactions were related to sexual function. 3.7% (57 patients) treated with Tricoplus and 2.1% (32 patients) treated with placebo discontinued therapy as a result of adverse reactions related to sexual function, which are the most frequently reported adverse reactions.
Table 1 presents the only clinical adverse reactions considered possibly, probably or definitely drug related by the investigator, for which the incidence on Tricoplus 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 of impotence, decreased libido and ejaculation disorder.
Phase III Studies and 5-Year Open Extensions
The adverse experience profile in the 1-year, placebo-controlled, Phase III studies, the 5-year open extensions, and PLESS were similar.
Medical Therapy of Prostatic Symptoms (MTOPS) Study
In the MTOPS study, 3047 men with symptomatic BPH were randomized to receive Tricoplus 5 mg/day (n=768), doxazosin 4 or 8 mg/day (n=756), the combination of Tricoplus 5 mg/day and doxazosin 4 or 8 mg/day (n=786), or placebo (n=737) for 4 to 6 years.
The incidence rates of drug-related adverse experiences reported by ≥2% of patients in any treatment group in the MTOPS Study are listed in Table 2.
The individual adverse effects which occurred more frequently in the combination group compared to either drug alone were: asthenia, postural hypotension, peripheral edema, dizziness, decreased libido, rhinitis, abnormal ejaculation, impotence and abnormal sexual function. Of these, the incidence of abnormal ejaculation in patients receiving combination therapy was comparable to the sum of the incidences of this adverse experience reported for the two monotherapies.
Combination therapy with Tricoplus and doxazosin was associated with no new clinical adverse experience.
Four patients in MTOPS reported the adverse experience breast cancer. Three of these patients were on Tricoplus only and one was on combination therapy.
The MTOPS Study was not specifically designed to make statistical comparisons between groups for reported adverse experiences. In addition, direct comparisons of safety data between the MTOPS study and previous studies of the single agents may not be appropriate based upon differences in patient population, dosage or dose regimen, and other procedural and study design elements.
High-Grade Prostate Cancer
The PCPT trial was a 7-year randomized, double-blind, placebo-controlled trial that enrolled 18,882 men ≥55 years of age with a normal digital rectal examination and a PSA ≤3.0 ng/mL. Men received either Tricoplus (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 Tricoplus (1.8%) than in those treated with placebo (1.1%) . In a 4-year placebo-controlled clinical trial with another 5α-reductase inhibitor (dutasteride, AVODART), similar results for Gleason score 8-10 prostate cancer were observed (1% dutasteride vs 0.5% placebo).
No clinical benefit has been demonstrated in patients with prostate cancer treated with Tricoplus.
During the 4- to 6-year placebo- and comparator-controlled MTOPS study that enrolled 3047 men, there were 4 cases of breast cancer in men treated with Tricoplus but no cases in men not treated with Tricoplus. 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 in men treated with Tricoplus. 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 Tricoplus, and 1 case of breast cancer in men treated with placebo. The relationship between long-term use of Tricoplus and male breast neoplasia is currently unknown.
There is no evidence of increased sexual adverse experiences with increased duration of treatment with Tricoplus. New reports of drug-related sexual adverse experiences decreased with duration of therapy.
6.2 Postmarketing Experience
The following additional adverse events have been reported in postmarketing experience with Tricoplus. Because these events 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:
The following additional adverse event related to sexual dysfunction that continued after discontinuation of treatment has been reported in postmarketing experience with Tricoplus at lower doses used to treat male pattern baldness. Because the event is reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate its frequency or establish a causal relationship to drug exposure:
7 DRUG INTERACTIONS
7.1 Cytochrome P450-Linked Drug Metabolizing Enzyme System
No drug interactions of clinical importance have been identified. Tricoplus does not appear to affect the cytochrome P450-linked drug metabolizing enzyme system. Compounds that have been tested in man have included 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, Tricoplus was concomitantly used in clinical studies with acetaminophen, acetylsalicylic acid, α-blockers, angiotensin-converting enzyme (ACE) inhibitors, analgesics, anti-convulsants, beta-adrenergic blocking agents, diuretics, calcium channel blockers, cardiac nitrates, HMG-CoA reductase inhibitors, nonsteroidal anti-inflammatory drugs (NSAIDs), benzodiazepines, H2 antagonists and quinolone anti-infectives without evidence of clinically significant adverse interactions.
8 USE IN SPECIFIC POPULATIONS
Pregnancy Category X.
Tricoplus is contraindicated for use in women who are or may become pregnant. Tricoplus 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, Tricoplus 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 5α-dihydrotestosterone (DHT) is inhibited by 5α-reductase inhibitors. These outcomes are similar to those reported in male infants with genetic 5α-reductase deficiency. Women could be exposed to Tricoplus through contact with crushed or broken Tricoplus tablets or semen from a male partner taking Tricoplus. With regard to Tricoplus exposure through the skin, Tricoplus tablets are coated and will prevent skin contact with Tricoplus during normal handling if the tablets have not been crushed or broken. Women who are pregnant or may become pregnant should not handle crushed or broken Tricoplus tablets because of possible exposure of a male fetus. If a pregnant woman comes in contact with crushed or broken Tricoplus tablets, the contact area should be washed immediately with soap and water. With regard to potential Tricoplus exposure through semen, two studies have been conducted in men receiving Tricoplus 5 mg/day that measured Tricoplus concentrations in semen .
In an embryo-fetal development study, pregnant rats received Tricoplus during the period of major organogenesis (gestation days 6 to 17). At maternal doses of oral Tricoplus approximately 0.1 to 86 times the maximum recommended human dose (MRHD) of 5 mg/day (based on AUC at animal doses of 0.1 to 100 mg/kg/day) there was a dose-dependent 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 for differentiation of the external genitalia. At oral maternal doses approximately 0.03 times the MRHD (based on AUC at animal 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 of pregnant rats that received approximately 0.003 times the MRHD (based on AUC at animal dose of 0.003 mg/kg/day). No abnormalities were observed in female offspring at any maternal dose of Tricoplus.
No developmental abnormalities were observed in the offspring of untreated females mated with Tricoplus treated male rats that received approximately 61 times the MRHD (based on AUC at animal dose of 80 mg/kg/day). Slightly decreased fertility was observed in male offspring after administration of about 3 times the MRHD (based on AUC at animal dose of 3 mg/kg/day) to female rats during late gestation and lactation. No effects on fertility were seen in female offspring under these conditions.
No evidence of male external genital malformations or other abnormalities were observed in rabbit fetuses exposed to Tricoplus during the period of major organogenesis (gestation days 6-18) at maternal oral 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 Tricoplus effects on development of male external genitalia in the rabbit.
The fetal effects of maternal Tricoplus 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 of specific effects in humans than the studies in rats and rabbits. Intravenous administration of Tricoplus to pregnant monkeys at doses as high as 800 ng/day (estimated maximal blood concentration of 1.86 ng/mL or about 143 times the highest estimated exposure of pregnant women to Tricoplus from semen of men taking 5 mg/day) resulted in no abnormalities in male fetuses. In confirmation of the relevance of the rhesus model for human fetal development, oral administration of a dose of Tricoplus (2 mg/kg/day or approximately 18,000 times the highest estimated blood levels of Tricoplus from semen of men taking 5 mg/day) to pregnant monkeys resulted in external genital abnormalities 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
Tricoplus is not indicated for use in women.
It is not known whether Tricoplus is excreted in human milk.
8.4 Pediatric Use
Tricoplus is not indicated for use in pediatric patients.
Safety and effectiveness in pediatric patients have not been established.
8.5 Geriatric Use
Of the total number of subjects included in PLESS, 1480 and 105 subjects were 65 and over and 75 and over, respectively. No overall differences in safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients. No dosage adjustment is necessary in the elderly .
8.6 Hepatic Impairment
Caution should be exercised in the administration of Tricoplus in those patients with liver function abnormalities, as Tricoplus is metabolized extensively in the liver .
8.7 Renal Impairment
No dosage adjustment is necessary in patients with renal impairment .
Patients have received single doses of Tricoplus up to 400 mg and multiple doses of Tricoplus up to 80 mg/day for three months without adverse effects. Until further experience is obtained, no specific treatment for an overdose with Tricoplus can be recommended.
Significant lethality was observed in male and female mice at single oral doses of 1500 mg/m2 (500 mg/kg) and in female and male rats at single oral doses of 2360 mg/m2 (400 mg/kg) and 5900 mg/m2 (1000 mg/kg), respectively.
Tricoplus, a synthetic 4-azasteroid compound, is a specific inhibitor of steroid Type II 5α-reductase, an intracellular enzyme that converts the androgen testosterone into 5α-dihydrotestosterone (DHT).
Tricoplus is 4-azaandrost-1-ene-17-carboxamide, N-(1,1-dimethylethyl)-3-oxo-,(5α,17ß)-. The empirical formula of Tricoplus is C23H36N2O2 and its molecular weight is 372.55. Its structural formula is:
Results seen in earlier studies were comparable to those seen in PLESS. Although an early improvement in urinary symptoms was seen in some patients, a therapeutic trial of at least 6 months was generally necessary to assess whether a beneficial response in symptom relief had been achieved. The improvement in BPH symptoms was seen during the first year and maintained throughout an additional 5 years of open extension studies.
Effect on Acute Urinary Retention and the Need for Surgery
In PLESS, efficacy was also assessed by evaluating treatment failures. Treatment failure was prospectively defined as BPH-related urological events or clinical deterioration, lack of improvement and/or the need for alternative therapy. BPH-related urological events were defined as urological surgical intervention and acute urinary retention requiring catheterization. Complete event information was available for 92% of the patients. The following table (Table 5) summarizes the results.
Compared with placebo, Tricoplus was associated with a significantly lower risk for acute urinary retention or the need for BPH-related surgery [13.2% for placebo vs 6.6% for Tricoplus; 51% reduction in risk, 95% CI: (34 to 63%)]. Compared with placebo, Tricoplus was associated with a significantly lower risk for surgery [10.1% for placebo vs 4.6% for Tricoplus; 55% reduction in risk, 95% CI: (37 to 68%)] and with a significantly lower risk of acute urinary retention [6.6% for placebo vs 2.8% for Tricoplus; 57% reduction in risk, 95% CI: (34 to 72%)]; see Figures 2 and 3.
Effect on Maximum Urinary Flow Rate
In the patients in PLESS who remained on therapy for the duration of the study and had evaluable urinary flow data, Tricoplus increased maximum urinary flow rate by 1.9 mL/sec compared with 0.2 mL/sec in the placebo group.
There was a clear difference between treatment groups in maximum urinary flow rate in favor of Tricoplus by month 4 (1.0 vs 0.3 mL/sec) which was maintained throughout the study. In the earlier 1-year studies, increase in maximum urinary flow rate was comparable to PLESS and was maintained through the first year and throughout an additional 5 years of open extension studies.
Effect on Prostate Volume
In PLESS, prostate volume was assessed yearly by magnetic resonance imaging (MRI) in a subset of patients. In patients treated with Tricoplus who remained on therapy, prostate volume was reduced compared with both baseline and placebo throughout the 4-year study. Tricoplus decreased prostate volume by 17.9% (from 55.9 cc at baseline to 45.8 cc at 4 years) compared with an increase of 14.1% (from 51.3 cc to 58.5 cc) in the placebo group (p<0.001).
Results seen in earlier studies were comparable to those seen in PLESS. Mean prostate volume at baseline ranged between 40-50 cc. The reduction in prostate volume was seen during the first year and maintained throughout an additional five years of open extension studies.
Prostate Volume as a Predictor of Therapeutic Response
A meta-analysis combining 1-year data from seven double-blind, placebo-controlled studies of similar design, including 4491 patients with symptomatic BPH, demonstrated that, in patients treated with Tricoplus, the magnitude of symptom response and degree of improvement in maximum urinary flow rate were greater in patients with an enlarged prostate at baseline.
14.2 Combination with Alpha-Blocker Therapy
The Medical Therapy of Prostatic Symptoms (MTOPS) Trial was a double-blind, randomized, placebo-controlled, multicenter, 4- to 6-year study (average 5 years) in 3047 men with symptomatic BPH, who were randomized to receive Tricoplus 5 mg/day (n=768), doxazosin 4 or 8 mg/day (n=756), the combination of Tricoplus 5 mg/day and doxazosin 4 or 8 mg/day (n=786), or placebo (n=737). All participants underwent weekly titration of doxazosin (or its placebo) from 1 to 2 to 4 to 8 mg/day. Only those who tolerated the 4 or 8 mg dose level were kept on doxazosin (or its placebo) in the study. The participant's final tolerated dose (either 4 mg or 8 mg) was administered beginning at end-Week 4. The final doxazosin dose was administered once per day, at bedtime.
The mean patient age at randomization was 62.6 years (±7.3 years). Patients were Caucasian (82%), African American (9%), Hispanic (7%), Asian (1%) or Native American (<1%). The mean duration of BPH symptoms was 4.7 years (±4.6 years). Patients had moderate to severe BPH symptoms at baseline with a mean AUA symptom score of approximately 17 out of 35 points. Mean maximum urinary flow rate was 10.5 mL/sec (±2.6 mL/sec). The mean prostate volume as measured by transrectal ultrasound was 36.3 mL (±20.1 mL). Prostate volume was ≤20 mL in 16% of patients, ≥50 mL in 18% of patients and between 21 and 49 mL in 66% of patients.
The primary endpoint was a composite measure of the first occurrence of any of the following five outcomes: a ≥4 point confirmed increase from baseline in symptom score, acute urinary retention, BPH-related renal insufficiency (creatinine rise), recurrent urinary tract infections or urosepsis, or incontinence. Compared to placebo, treatment with Tricoplus, doxazosin, or combination therapy resulted in a reduction in the risk of experiencing one of these five outcome events by 34% (p=0.002), 39% (p<0.001), and 67% (p<0.001), respectively. Combination therapy resulted in a significant reduction in the risk of the primary endpoint compared to treatment with Tricoplus alone (49%; p≤0.001) or doxazosin alone (46%; p≤0.001).
The majority of the events (274 out of 351; 78%) was a confirmed ≥4 point increase in symptom score, referred to as symptom score progression. The risk of symptom score progression was reduced by 30% (p=0.016), 46% (p<0.001), and 64% (p<0.001) in patients treated with Tricoplus, doxazosin, or the combination, respectively, compared to patients treated with placebo. Combination therapy significantly reduced the risk of symptom score progression compared to the effect of Tricoplus alone (p<0.001) and compared to doxazosin alone (p=0.037).
Treatment with Tricoplus, doxazosin or the combination of Tricoplus with doxazosin, reduced the mean symptom score from baseline at year 4. Table 7 provides the mean change from baseline for AUA symptom score by treatment group for patients who remained on therapy for four years.
The results of MTOPS are consistent with the findings of the 4-year, placebo-controlled study PLESS in that treatment with Tricoplus reduces the risk of acute urinary retention and the need for BPH-related surgery. In MTOPS, the risk of developing acute urinary retention was reduced by 67% in patients treated with Tricoplus compared to patients treated with placebo (0.8% for Tricoplus and 2.4% for placebo). Also, the risk of requiring BPH-related invasive therapy was reduced by 64% in patients treated with Tricoplus compared to patients treated with placebo (2.0% for Tricoplus and 5.4% for placebo).
14.3 Summary of Clinical Studies
The data from these studies, showing improvement in BPH-related symptoms, reduction in treatment failure (BPH-related urological events), increased maximum urinary flow rates, and decreasing prostate volume, suggest that Tricoplus arrests the disease process of BPH in men with an enlarged prostate.

What is BPH?
BPH is an enlargement of the prostate gland. The prostate is located below the bladder. As the prostate enlarges, it may slowly restrict the flow of urine. This can lead to symptoms such as:
In some men, BPH can lead to serious problems, including urinary tract infections, a sudden inability to pass urine (acute urinary retention), as well as the need for surgery.
What Tricoplus does:
Tricoplus lowers levels of a hormone called DHT (dihydrotestosterone), which is a cause of prostate growth. Lowering DHT leads to shrinkage of the enlarged prostate gland in most men. This can lead to gradual improvement in urine flow and symptoms over the next several months. Tricoplus will help reduce the risk of developing a sudden inability to pass urine and the need for surgery related to an enlarged prostate. However, since each case of BPH is different, you should know that:
