Revised: Feb 2018 Side Effects & Drug Interactions SIDE EFFECTS 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 practice. In four (4) placebo-controlled, 12-week clinical trials [91% -White Caucasian non-Hispanic women, 7% -Black or African American women, and 2% -“Other” women, average age 58.8 years of age (range 40 to 80 years of age)], vaginal discharge is the most frequently reported treatment-emergent adverse reaction in the INTRAROSA treatment group with an incidence of ≥ 2 percent and greater than reported in the placebo treatment group. There were 38 cases in 665 participating postmenopausal women (5.71 percent) in the INTRAROSA treatment group compared to 17 cases in 464 participating postmenopausal women (3.66 percent) in the placebo treatment group. In a 52-week non-comparative clinical trial [92% -White Caucasian non-Hispanic women, 6% Black or African American women, and 2% -“Other” women, average age 57.9 years of age (range 43 to 75 years of age)], vaginal discharge and abnormal Pap smear at 52 weeks were the most frequently reported treatment-emergent adverse reaction in women receiving INTRAROSA with an incidence of ≥ 2 percent. There were 74 cases of vaginal discharge (14.2 percent) and 11 cases of abnormal Pap smear (2.1 percent) in 521 participating postmenopausal women. The eleven (11) cases of abnormal Pap smear at 52 weeks include one (1) case of low-grade squamous intraepithelial lesion (LSIL), and ten (10) cases of atypical cells of undetermined significance (ASCUS). DRUG INTERACTIONS No Information provided Warnings & Precautions WARNINGS Included as part of the PRECAUTIONS section. PRECAUTIONS Current Or Past History Of Breast Cancer Estrogen is a metabolite of prasterone. Use of exogenous estrogen is contraindicated in women with a known or suspected history of breast cancer. INTRAROSA has not been studied in women with a history of breast cancer. Patient Counseling Information Advise the patient to read FDA-approved patient labeling (Patient Information and Instructions for Use). Vaginal Discharge Inform postmenopausal women that vaginal discharge may occur with INTRAROSA[see ADVERSE REACTIONS]. Abnormal Pap Smear Findings Inform postmenopausal women that abnormal Pap smear findings may occur with INTRAROSA [see ADVERSE REACTIONS]. Nonclinical Toxicology Carcinogenesis, Mutagenesis, Impairment Of Fertility Carcinogenesis Long-term studies in animals to evaluate carcinogenic potential have not been conducted with prasterone.Two metabolites of prasterone, testosterone and estradiol, are carcinogenic in animals. Mutagenesis Prasterone was not genotoxic in the in vitro bacterial mutagenesis assay (Ames test), the in vitro chromosomal aberrations assay with human peripheral blood lymphocytes, and in vivo in the mouse bone marrow micronucleus assay. Fertility Fertility studies were not conducted with prasterone. Use In Specific Populations Pregnancy Risk Summary INTRAROSA is indicated only in postmenopausal women.There are no data with INTRAROSA use in pregnant women regarding any drug-associated risks. Animal reproduction studies have not been conducted with prasterone. Lactation Risk Summary INTRAROSA is indicated only in postmenopausal women.There is no information on the presence of prasterone in human milk, the effects on the breastfed infant, or the effects on milk production. Pediatric Use Safety and effectiveness have not been established in pediatric patients. Geriatric Use Of the 1522 prasterone-treated postmenopausal women enrolled in the four placebo-controlled 12-week and one open-label 52-week clinical trial, 19and 11 percent, respectively, were 65 years of age or older. Renal Impairment The effect of renal impairment on the pharmacokinetics of prasterone has not been studied. Hepatic Impairment The effect of hepatic impairment on the pharmacokinetics of prasterone has not been studied. Overdosage & Contraindications OVERDOSE No Information provided CONTRAINDICATIONS Undiagnosed abnormal genital bleeding: Any postmenopausal woman with undiagnosed, persistent or recurring genital bleeding should be evaluated to determine the cause of the bleeding before consideration of treatment with INTRAROSA. Clinical Pharmacology CLINICAL PHARMACOLOGY Mechanism Of Action Prasterone is an inactive endogenous steroid and is converted into active androgens and/or estrogens.The mechanism of action of INTRAROSA in postmenopausal women with vulvar and vaginal atrophy is not fully established. Pharmacokinetics In a study conducted in postmenopausal women, administration of the INTRAROSA vaginal insert once daily for 7 days resulted in a mean prasterone Cmax and area under the curve from 0 to 24 hours (AUC0-24) at Day 7 of 4.4 ng/mL and 56.2 ng•h/mL, respectively, which were significantly higher than those in the group treated with placebo (Table 1). The Cmax and AUC0-24 of the metabolites testosterone and estradiol were also slightly higher in women treated with the INTRAROSA vaginal insert compared to those receiving placebo. Table 1. Cmax and AUC0-24 of Prasterone, Testosterone, and Estradiol on Day 7 Following Daily Administration of Placebo or INTRAROSA (mean ± S.D). Placebo (N=9) INTRAROSA (N=10) Prasterone Cmax (ng/mL) 1.60 (±0.95) 4.42 (±1.49) AUC0-24 (ng•h/mL) 24.82 (±14.31) 56.17 (±28.27) Testosterone Cmax (ng/mL) 0.12 (±0.04)1 0.15 (±0.05) AUC0-24 (ng•h/mL) 2.58 (±0.94)1 2.79 (±0.94) Estradiol Cmax(pg/mL) 3.33 (±1.31) 5.04 (±2.68) AUC0-24 (pg•h/mL) 66.49 (±20.70) 96.93 (±52.06) 1 : N=8 Figure 1: Serum Concentrations of Prasterone (A), Testosterone (B), and Estradiol (C) Measured Over a 24h Period on Day 7Following Daily Administration of Placebo or INTRAROSA (mean ± S.D.). In two primary efficacy trials, daily administration of INTRAROSA vaginal insert for 12 weeks increased mean serum Ctrough of prasterone and its metabolites testosterone and estradiol by 47%, 21% and 19% from baseline, respectively. This comparison based on Ctrough may underestimate the magnitude of increase in prasterone and metabolites’ exposure because it does not take into account the overall concentration-time profile following administration of INTRAROSA. Metabolism Exogenous prasterone is metabolized in the same manner as endogenous prasterone. Human steroidogenic enzymes such as hydroxysteroid dehydrogenases, 5α-reductases and aromatases transform prasterone into androgens and estrogens. Clinical Studies The effectivenessof INTRAROSA on moderate to severe dyspareunia, a symptom of vulvar and vaginal atrophy, due to menopause was examined in twoprimary12-week placebo-controlled efficacy trials. The first clinical trial (Trial 1) was a 12-week randomized, double-blind and placebocontrolledtrial that enrolled 255 generally healthy postmenopausal women between 40 to 75 years of age (mean 58.6 years) who, at baseline, identified moderate to severe dyspareunia as their most bothersome symptom of vulvar and vaginal atrophy. In addition to moderate to severe dyspareunia, women had ≤ 5% superficial cells on vaginal smear and a vaginal pH > 5.Women were randomized in a 1:1:1 ratio between three treatment groups who received daily INTRAROSA(n=87),one active comparator vaginal insert (n=87), or placebo (n=81). All women were assessed for improvement from Baseline to Week 12 for fourco-primary efficacy endpoints: most bothersome moderate to severe symptom of dyspareunia, the percentage of vaginal superficial cells, the percentage of parabasal cells, and vaginal pH. The second clinical trial (Trial 2) was a 12-week randomized, double-blind and placebocontrolledtrial that enrolled 558 generally healthy postmenopausal women between 40 to 80 years of age (mean 59.5 years) who, at baseline, had identified moderate to severe dyspareunia as their most bothersome symptom of vulvar and vaginal atrophy. In addition to dyspareunia, women had ≤ 5% superficial cells on vaginal smear and a vaginal pH > 5. Women were randomized in a 2:1 ratio to receive once daily vaginal insert containing 6.5 mg INTRAROSA (n=376) or placebo (n=182). The primary endpoints and study conduct were the same or similar to those in Trial 1. The primary efficacy results obtained in the Intent-to-Treat (ITT) population in Trial 1 are shown in Table 2.
