Side Effects & Drug Interactions

SIDE EFFECTS

The following serious adverse reactions are discussed elsewhere in the labeling:

Clinical Study 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.

The safety data described in Table 1 reflect exposure to MILPROSA (up to 10 weeks) in 647 infertile women (80% Caucasian, 8% African-American, 5% Hispanic, 5% Asian) in a single prospective, randomized, active concurrently-controlled clinical trial of progesterone supplementation in women undergoing in-vitro fertilization (IVF) in the U.S. [see Clinical Studies]. Adverse reactions that occurred at a rate greater than or equal to 2% in the MILPROSA treatment group are summarized in Table 1.

Table 1: Number and Frequency of Adverse Reactions in Women Treated with MILPROSA in an Assisted Reproductive Technology Study (≥2%)

Preferred TermMILPROSA
(N=647)
Headache44 (7%)
Vaginal discharge26 (4%)
Nausea25 (4%)
Breast tenderness24 (4%)
Post procedural discomfort24 (4%)
Abdominal distension22 (3%)
Abdominal pain19 (3%)
Pelvic pain19 (3%)
Constipation17 (3%)

Additional safety data following exposure to MILPROSA was collected in a multi-center, non-comparative, open-label, single-arm study of women undergoing Assisted Reproductive Technology in the U.S. The population consisted of 254 infertile women 18-34 years of age (83% Caucasian, 7% African-American, 9% Asian,1% American Indian) who were exposed up to 10 weeks. The adverse reaction profile was consistent with previous observations.

Adverse reactions associated with other drugs containing progesterone include bloating, mood swings, irritability, and drowsiness.

DRUG INTERACTIONS

No formal drug-drug interaction studies have been conducted for MILPROSA. Drugs known to induce the hepatic CYP3A4 enzyme (such as rifampin, carbamazepine) may increase the elimination of progesterone. The effect of concomitant vaginal products on the exposure of progesterone from MILPROSA has not been assessed. MILPROSA is not recommended for use with other vaginal products (such as antifungal products, vaginal lubricants, diaphragms and condoms) as this may alter progesterone release and absorption from the vaginal system [see WARNINGS AND PRECAUTIONS].

Warnings & Precautions

WARNINGS

Included as part of the "PRECAUTIONS" Section

PRECAUTIONS

Cardiovascular Or Cerebrovascular Disorders

Be alert to early signs of myocardial infarction, cerebrovascular disorders, arterial or venous thromboembolism (venous thromboembolism or pulmonary embolism), thrombophlebitis, or retinal thrombosis in women using MILPROSA. Discontinue MILPROSA if any of these are suspected.

Depression

Observe closely women with a history of depression who use MILPROSA. Discontinue MILPROSA if symptoms of depression worsen.

Toxic Shock Syndrome

Cases of toxic shock syndrome (TSS) have been reported in women using vaginal systems with and without tampon use. No causal relationship between the use of MILPROSA and TSS has been established. Warning signs of TSS include fever, nausea, vomiting, diarrhea, muscle pain, dizziness, faintness or a sunburn-like rash on face and body. Discontinue MILPROSA if TSS is suspected. and initiate appropriate medical evaluation and treatment.

Use Of Other Vaginal Products

Concomitant use of MILPROSA with other vaginal products (such as antifungal products, vaginal lubricants, diaphragms and condoms) has not been studied; these products may alter progesterone release and absorption from MILPROSA [see DRUG INTERACTIONS]. If possible, avoid use of other vaginal products with MILPROSA.

Patient Counseling Information

Advise the patient to read the FDA-approved patient labeling (Instructions for Use).

Inform women:

  • Of the importance of reporting irregular vaginal bleeding to their doctor as soon as possible.
  • Of the possible side effects of progesterone therapy such as headaches, abdominal pain, breast tenderness, bloating, mood swings, irritability, and drowsiness.
  • To leave the vaginal system in place continuously (for a minimum of 23 hours per day) [see DOSAGE AND ADMINISTRATION]. It may be removed for sexual intercourse, although this is not necessary.
  • MILPROSA is not recommended for use with other vaginal products (such as antifungal products, vaginal lubricants, diaphragms, and condoms) as this concomitant use has not been studied and may alter the progesterone release and absorption from the vaginal system [see WARNINGS AND PRECAUTIONS and DRUG INTERACTIONS].

Nonclinical Toxicology

Carcinogenesis, Mutagenesis, Impairment Of Fertility

Nonclinical toxicity studies to determine the potential of MILPROSA to cause carcinogenicity or mutagenicity have not been performed. The effect of MILPROSA on fertility has not been evaluated in animals.

Use In Specific Populations

Pregnancy

Risk Summary

MILPROSA is indicated to support embryo implantation and early pregnancy as part of an assisted reproductive technology treatment program in vitro fertilization (IVF) with or without intracytoplasmic sperm injection (ICSI) and embryo transfer for infertile women. Maternal risks are discussed throughout the labeling.

In the US general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

Data

Human Data

MILPROSA has been used to support embryo implantation during the first trimester of pregnancy and to maintain clinical pregnancy as part of an ART regimen. Exposure in pregnancy with use of MILPROSA occurs from implantation of an embryo through week 10 of pregnancy when the placenta takes over production of progesterone.

In clinical trials, among 813 women less than 35 years of age who were treated with MILPROSA, 75 (9.2%) had a spontaneous abortion and 6 (0.7%) had an ectopic pregnancy. Of the 813 women less than 35 years of age, 559 (68.8%) were planned to be followed through birth. Among the 559 to be followed through birth, 263 (47.0%) had livebirths consisting of 154 (58.6%) singletons, 102 (38.8%) twins, and 7 (2.7%) triplets. In this same cohort of treatment, 10 (1.8%) had a second or third trimester loss. Neonatal birth defects were reported in 8 (2.1%) of infants based on 379 liveborn infants. In the 2.1% of live born infants with birth defects for women less than 35 years of age treated with MILPROSA the following were noted: Turner’s syndrome; Tetralogy of Fallot; and congenital anomalies including left foot deformity, hypospadias, pyloric stenosis, spina bifida, multiple congenital anomalies, and multiple congenital anomalies with VACTERL association.

Lactation

Risk Summary

Detectable amounts of progesterone have been identified in the milk of nursing mothers. The effect of this on the nursing infant has not been determined. A published study reported no adverse effects of progesterone on milk production or infant growth during the first postpartum year. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for MILPROSA and any potential adverse effects on the breastfed child from MILPROSA or from the underlying maternal condition.

Pediatric Use

The safety and effectiveness of MILPROSA have not been established in pediatric patients.

Geriatric Use

Clinical studies of MILPROSA did not include women 65 years of age and older. MILPROSA is not indicated in this population.

Body Mass Index (BMI)

The safety and efficacy of MILPROSA in women with a BMI >38 kg/m2 has not been studied.

Hepatic Impairment

MILPROSA has not been studied in women with hepatic impairment.

Clinical Pharmacology

CLINICAL PHARMACOLOGY

Mechanism Of Action

Progesterone is a naturally occurring steroid that is secreted by the ovary, placenta, and adrenal gland. In the presence of adequate estrogen, progesterone transforms a proliferative endometrium into a secretory endometrium. Progesterone is necessary to increase endometrial receptivity for implantation of an embryo. Once an embryo is implanted, progesterone acts to maintain a pregnancy.

Pharmacokinetics

Absorption

Progesterone plasma concentrations increased following the administration of MILPROSA vaginal system to 30 healthy postmenopausal females (inserted once a week for two weeks) (MILPROSA is not indicated in postmenopausal females). The 30 subjects were pre-treated with 1 mg oral estradiol tablets once a day for 28 days prior to MILPROSA treatment and during MILPROSA treatment to manage postmenopausal vaginal atrophy. Steady state concentrations were attained 96 hours after initiation of treatment with MILPROSA. After reaching steady state, MILPROSA provided average baseline-adjusted plasma concentrations of progesterone exceeding 8 ng/mL. The pharmacokinetic results are summarized in Table 2.

Distribution

Progesterone is approximately 95% to 98% bound to serum proteins, primarily to serum albumin and corticosteroid binding globulin.

Elimination

The mean (± standard deviation) elimination half-life of progesterone delivered by MILPROSA is 10.82 ± 4.27 hours.

Metabolism

Progesterone is metabolized primarily by the liver largely to pregnanediols and pregnanolones, which are conjugated to glucuronide and sulfate metabolites [See CONTRAINDICATIONS].

Excretion

Progesterone undergoes both biliary and renal elimination. Following an intravenous injection of labeled progesterone, 50%-60% of the excretion of metabolites occurs via the kidney; approximately 10% occurs via the bile and feces. Overall recovery of the labeled material accounts for 70% of an administered dose. Only 0.1% of unchanged progesterone is excreted in the bile.

Clinical Studies

Luteal Supplementation During Assisted Reproductive Treatment Trial

A single prospective, randomized, assessor-blind, active concurrently -controlled trial evaluated the efficacy of 10 weeks of treatment with MILPROSA for support of implantation and early pregnancy in infertile women participating in an Assisted Reproductive Technology treatment program. Women were eligible for the trial if there was tubal, idiopathic, male factor, ovulatory dysfunction or endometriosis-linked infertility, documentation of a normal uterine cavity within 1 year of screening, and a source of fresh or frozen sperm meeting standard criteria. Women were not included in the trial if they had conditions which contraindicated the use of progesterone; hypersensitivity or intolerance to silicone; history of pelvic irradiation, endometrial cancer, toxic shock syndrome, more than one failed fresh in vitro fertilization (IVF) cycle, more than two consecutive clinically recognized miscarriages, or HIV/AIDS; uncontrolled hypertension, hyperprolactinemia, or hypothyroidism; body mass index (BMI) greater than 38 kg/m2, clinically significant endometrial pathology or a communicating hydrosalpinx; and a male partner with non-obstructive azoospermia for couples using fresh sperm.

Prior to IVF with or without intracytoplasmic sperm injection (ICSI), eligible women were started on an ovarian down-regulation protocol which begin during the cycle immediately prior to the embryo transfer cycle. Ovarian stimulation with gonadotropins products was begun once down-regulation was achieved. The length of stimulation was individualized per the trial investigational site’s standard protocol(s), and/or the trial investigator’s clinical judgment. During stimulation, the participating woman was monitored to determine when to trigger ovulation with human chorionic gonadotropin (hCG).

Egg retrieval occurred approximately 35 to 37 hours after hCG administration. On the day after egg retrieval, at the time of consent, eligible women were stratified by age and randomized in a 1:1 ratio to MILPROSA, one vaginal insert every week, or the active comparator once daily. Embryo transfer occurred 3 to 5 days after egg retrieval. A serum pregnancy test was conducted 2 weeks after egg retrieval. Women whose serum ß-hCG was less than 5 mIU were discontinued from the study. Those with a serum ß-hCG greater than 5 continued dosing with MILPROSA or active comparator for up to a total of 10 weeks (i.e., through 12 weeks of pregnancy).

Efficacy was assessed by the co-primary endpoints of clinically recognized pregnancy rate, defined as the presence of at least one fetal heartbeat seen on ultrasound at 6 weeks and at 10 weeks post-embryo transfer. The trial randomized 646 infertile women to the MILPROSA vaginal system arm and 651 infertile women to the active control arm. Women receiving MILPROSA were 80% Caucasian, 8% African-American, 5% Hispanic, 5% Asian) and between 20 and 42 years of age (mean age 31.7) with a body mass index of 38 kg/m2 or less at screening. Women in the active control arm demonstrated similar demographics.

The primary efficacy analysis set was the modified intent-to-treat population (MITT), which included all women having successful egg retrieval and having at least one dose of progesterone. Women who terminated the study prior to 6 weeks after egg retrieval were considered treatment failures at both 6 and 10 weeks. The clinical pregnancy rates at Weeks 6 and 10 were compared between the MILPROSA arm and the active comparator arm at a one-sided alpha of 0.025. The 95% confidence interval (CI) for the difference in pregnancy rate was calculated using the normal approximation method. Treatment with MILPROSA was declared non-inferior to the active comparator if the lower bound of the 95% CI for the difference in pregnancy rate was greater than -10% based on MITT population. The results with the MILPROSA treatment are shown in Table 3.

Table 3: Clinical Pregnancy Rates in Patients Receiving MILPROSA for Luteal Supplementation and Early Pregnancy While in an Assisted Reproductive Technology Treatment Program (NCT00615251).

MILPROSA (N=646)
6 weeks post-embryo transfer
  Clinical Pregnancy: n (%)310 (48.0%)
  Pregnancy rate percentage difference between MILPROSA and comparator0.8%
  95% Confidence Interval for difference vs. comparator(-4.6%, 6.3%)
10 weeks post-embryo transfer
  Clinical Pregnancy: n (%)300 (46.4%)
  Pregnancy rate percentage difference between MILPROSA and comparator1.3%
  95% Confidence Interval for difference vs. comparator(-4.1%, 6.7%)

The pregnancy rates at Week 6 and Week 10 post embryo transfer for women treated with MILPROSA were non-inferior to those for women treated with the active comparator.

Women participating in the trial were stratified at randomization by age. The co-primary endpoints of the clinical pregnancy rate at Weeks 6 and 10 post embryo transfer were also evaluated by age groups 18-34 and 35-42. In women under the age of 35, the pregnancy rates with MILPROSA were 49.3 % and 48.2% respectively at Weeks 6 and 10 post embryo transfer and these rates were non-inferior to the rates for women treated with the active comparator and evaluated at the same time points. The trial was insufficiently powered to provide meaningful comparisons for women age 35 and older.

Read this Instructions for Use carefully before you use MILPROSA and each time you get a refill. This information does not take the place of talking with your healthcare provider who specializes in women’s health. If you have any questions about MILPROSA, ask your healthcare provider.

Follow the steps below to insert MILPROSA:

Choose the position that is most comfortable for you such as lying down - Illustration

Hold MILPROSA between your thumb and index finger - Illustration

Use your other hand and hold open the folds of skin around your vagina - Illustration

Place the tip of MILPROSA in the vaginal opening - Illustration

You do not need to use anything else to place MILPROSA in the correct position. MILPROSA will change shape to fit your body. The exact position of MILPROSA is not important. The muscles of your vagina will keep MILPROSA securely in place. If you have difficulty inserting MILPROSA, it is fine to rinse the MILPROSA with cool to lukewarm (not hot) water before inserting it.

  1. Wash and dry your hands.
  2. Remove the MILPROSA vaginal system from its foil pouch. Keep the foil pouch so you can place your used MILPROSA in it before you throw it away. See “To throw away (dispose of) MILPROSA” instructions at the end of this Instructions for Use.
  3. Choose the position that is most comfortable for you such as lying down, squatting, or standing with 1 leg up.
  4. Hold MILPROSA between your thumb and index finger and gently squeeze the sides of MILPROSA together.
  5. Use your other hand and hold open the folds of skin around your vagina.
  6. Place the tip of MILPROSA in the vaginal opening and then use your index finger to push the folded MILPROSA gently into your vagina. Push MILPROSA up towards your lower back as far as you can. If you can feel MILPROSA, it may not be placed back far enough in your vagina. Use your index finger to push MILPROSA back a bit further. Put MILPROSA where it is comfortable for you. There is no danger of MILPROSA being pushed too far up in the vagina or getting lost.

In 7 days remove the old MILPROSA and replace with a new MILPROSA.

MILPROSA should remain in place for a minimum of 23 hours each day. You can remove MILPROSA for sexual intercourse, although this is not necessary.

If MILPROSA is expelled, removed, or dropped, it should be rinsed with cool to lukewarm (not hot) water and reinserted as soon as possible, except if MILPROSA touches or has feces on it. If MILPROSA touches or has feces on it, replace it with a new MILPROSA.

To remove MILPROSA:

  1. Wash your hands.
  2. Choose the position that is the most comfortable for you such as lying down, squatting, or standing with 1 leg up.
  3. Put a finger into your vagina and hook it through MILPROSA.
  4. Gently pull downwards and forward to remove MILPROSA.
