    What is Milprosa?

    • Milprosa is a vaginal system that contains the hormone progesterone. Milprosa is for infertile women who need extra progesterone while undergoing treatment in an Assisted Reproductive Technology (ART) program. Progesterone is one of the hormones essential for helping you to become and to stay pregnant. If you are undergoing ART treatment, your healthcare provider may prescribe Milprosa to provide the progesterone your body needs.

    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.

    Instructions for Use

    MILPROSA
    (mil-PRO-sah)
    (progesterone) vaginal system

    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.

    Removing MILPROSA - Illustration

    To throw away (dispose of) MILPROSA:

    1. Place the used MILPROSA in the foil pouch. If available, throw it away through a drug take-back option.
      or
    2. Place the used MILPROSA in the foil pouch and mix it with coffee grounds, dirt or cat litter.
    3. Place the foil pouch mixture in something that can be closed like a zipper storage bag, empty can, or other container and throw it away in your household trash out of the reach of children and pets.
    4. Do not flush the foil pouch down the toilet.
