Drug Details [pdf]

  • 1 INDICATIONS & USAGE

    Hydroxyprogesterone caproate injection is a progestin indicated to reduce the risk of preterm birth in women with a singleton pregnancy who have a history of singleton spontaneous preterm birth. The effectiveness of Hydroxyprogesterone caproate injection, USP is based on improvement in the proportion of women who delivered < 37 weeks of gestation. There are no controlled trials demonstrating a direct clinical benefit, such as improvement in neonatal mortality and morbidity.
    Limitation of use: While there are many risk factors for preterm birth, safety and efficacy of Hydroxyprogesterone caproate injection has been demonstrated only in women with a prior spontaneous singleton preterm birth. It is not intended for use in women with multiple gestations or other risk factors for preterm birth.

  • 2 DOSAGE & ADMINISTRATION

    2.1 Dosing

     Hydroxyprogesterone caproate injection (Single-dose vials): Administer intramuscularly at a dose of 250 mg (1 mL) once weekly (every 7 days) in the upper outer quadrant of the gluteus maximus by a healthcare provider
     Begin treatment between 16 weeks, 0 days and 20 weeks, 6 days of gestation
     Continue administration once weekly until week 37 (through 36 weeks, 6 days) of gestation or delivery, whichever occurs first

    2.2 Preparation and Administration

    Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Hydroxyprogesterone caproate injection is a clear, yellow solution. The solution must be clear at the time of use; replace vial if visible particles or crystals are present.

    Specific instructions for administration by dosage form:

    Hydroxyprogesterone caproate injection single-dose vials (intramuscular use only)

    Hydroxyprogesterone caproate injection single-dose vials are only for intramuscular injection with a syringe into the upper outer quadrant of the gluteus maximus, rotating the injection site to the alternate side from the previous week, using the following preparation and administration procedure:

    1. Clean the vial top with an alcohol swab before use.
    2. Draw up 1 mL of drug into a 3mL syringe with an 18 gauge needle.
    3. Change the needle to a 21 gauge 1½ inch needle.
    4. After preparing the skin, inject in the upper outer quadrant of the gluteus maximus. The solution is viscous and oily. Slow injection (over one minute or longer) is recommended.
    5. Applying pressure to the injection site may minimize bruising and swelling.

    5.4 Fluid Retention

    Because progestational drugs may cause some degree of fluid retention, carefully monitor women with conditions that might be influenced by this effect (e.g., preeclampsia, epilepsy, migraine, asthma,  cardiac  or renal dysfunction).

    5.5 Depression

    Monitor women who have a history of clinical depression and discontinue Hydroxyprogesterone caproate injection  if clinical depression recurs.

    5.6 Jaundice

    Carefully monitor women who develop jaundice while receiving Hydroxyprogesterone caproate injection and consider whether the benefit of use warrants continuation.

    5.7 Hypertension

    Carefully monitor women who develop hypertension while receiving Hydroxyprogesterone caproate injection and consider whether the benefit of use warrants continuation.

  • 6 ADVERSE REACTIONS

    For the most serious adverse reactions to the use of progestins, see Warnings and Precautions (5).

    6.1 Clinical Trials Experience

    Because clinical trials are conducted under widely varying conditions, adverse reaction rates observedin the clinical trials of a drug cannot be directly compared to the rates in the clinical trials of another   drug and may not reflect the rates observed in practice.

    In a vehicle (placebo)-controlled clinical trial of 463 pregnant women at risk for spontaneous pretermdelivery based on obstetrical history, 310 received 250 mg of Hydroxyprogesterone caproate injection and 153 received a vehicle formulation containing no drug by a weekly intramuscular injection beginning at 16 to 20 weeks of gestation and continuing until 37 weeks of gestation or delivery, whichever occurred first.[See Clinical Studies (14.1).]
    Certain pregnancy-related fetal and maternal complications or events were numerically increased in the Hydroxyprogesterone caproate injection-treated subjects as compared to control subjects, including miscarriage and stillbirth, admission for preterm labor, preeclampsia or gestational hypertension, gestational diabetes, and oligohydramnios (Tables 1 and 2).

    In the clinical trial using intramuscular injection, 2.2% of subjects receiving Hydroxyprogesterone caproate injection were reported as discontinuing therapy due to adverse reactions compared to 2.6% of control subjects. The most common adverse reactions that led todiscontinuation in both groups were urticaria and injection site pain/swelling (1% each).

    Pulmonary embolus in one subject and injection site cellulitis in another subject were reported as serious adverse reactions  in Hydroxyprogesterone caproate injection-treated subjects.

    6.2 Postmarketing Experience

    The following adverse reactions have been identified during postapproval use of Hydroxyprogesterone caproate injection . Because these reactions 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.

    • Body as a whole: Local injection site reactions (including erythema, urticaria, rash, irritation, hypersensitivity, warmth); fatigue; fever; hot flashes/flushes
    • Digestive disorders: Vomiting
    • Infections: Urinary tract infection
    • Nervous system  disorders: Headache, dizziness
    • Pregnancy, puerperium and perinatal conditions: Cervical incompetence, premature  rupture of membranes
    • Reproductive system and breast disorders: Cervical dilation, shortened  cervix
    • Respiratory disorders: Dyspnea, chest discomfort
    • Skin: Rash
  • 7 DRUG INTERACTIONS

    In vitro drug-drug interaction studies were conducted with Hydroxyprogesterone caproate injection. Hydroxyprogesterone caproate has minimal potential for CYP1A2, CYP2A6, and CYP2B6 related drug-drug interactions at the clinically relevant concentrations. In vitro data indicated that therapeutic concentration of hydroxyprogesterone caproate is not likely to inhibit the activity of CYP2C8, CYP2C9, CYP2C19, CYP2D6, CYP2E1, and CYP3A4[See Clinical Pharmacology (12.3).] No in vivo drug-drug interaction studies were conducted with Hydroxyprogesterone caproate injection.

  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Risk Summary
    Hydroxyprogesterone caproate injection is indicated to reduce the risk of preterm birth in women with a singleton pregnancy who have a history of singleton spontaneous preterm birth. Fetal, neonatal, and maternal risks are discussed throughout labeling. Data from the placebo-controlled clinical trial and the infant follow-up safety study [see Clinical Studies (14.1, 14.2)] did not show a difference in adverse developmental outcomes between children of Hydroxyprogesterone caproate injection-treated women and children of control subjects. However, these data are insufficient to determine a drug-associated risk of adverse developmental outcomes as none of the Hydroxyprogesterone caproate injection-treated women received the drug during the first trimester of pregnancy. In animal reproduction studies, intramuscular administration of hydroxyprogesterone caproate to pregnant rats during gestation at doses 5 times the human dose equivalent based on a 60-kg human was not associated with adverse developmental outcomes.

    In the U.S. 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

    Animal Data
    Reproduction studies of hydroxyprogesterone caproate administered to various animal species have been reported in the literature. In nonhuman primates, embryolethality was reported in rhesus monkeys administered hydroxyprogesterone caproate up to 2.4 and 24 times the human dose equivalent, but not in cynomolgus monkeys administered hydroxyprogesterone caproate at doses up to 2.4 times the human dose equivalent, every 7 days between days 20 and 146 of gestation. There were no teratogenic effects in either strain of monkey.

    Reproduction studies have been performed in mice and rats at doses up to 95 and 5, respectively, times the human dose and have revealed no evidence of impaired fertility or harm to the fetus due to hydroxyprogesterone caproate.

    8.2 Lactation

    Risk Summary
    Low levels of progestins are present in human milk with the use of progestin-containing products, including hydroxyprogesterone caproate. Published studies have reported no adverse effects of progestins on the breastfed child or on milk production.

    8.4 Pediatric Use

    Hydroxyprogesterone caproate injection is not indicated for use in women under 16 years of age. Safety and effectiveness in pediatric patients less than 16 years of age have not been established. A small number of women under age 18 years were studied; safety and efficacy are expected to be the same in women aged 16 years and above as for users 18 years and older. [See Clinical Studies (14).]

    8.6 Hepatic Impairment

    No studies have been conducted to examine the pharmacokinetics of Hydroxyprogesterone caproate injection in patients with hepatic impairment. Hydroxyprogesterone caproate injection is extensively metabolized and hepatic impairment may reduce the elimination of Hydroxyprogesterone caproate injection.

  • 10 OVERDOSAGE

    There have been no reports of adverse events associated with overdosage of Hydroxyprogesterone caproate injection in clinical trials. In the case of overdosage, the patient should be treated   symptomatically.

    Blood was drawn daily for 7 days (1) starting 24 hours after the first dose between Weeks 16­20 (Group 1), (2) after a dose between Weeks 24-28 (Group 2), or (3) after a dose between Weeks 32-36 (Group 3)

    a Reported as median (range)

    b t = 7 days

    For all three groups, peak concentration (Cmax) and area under the curve (AUC(1-7days)) of the mono-hydroxylated metabolites were approximately 3-8­ fold lower than the respective parameters for the parent drug, hydroxyprogesterone caproate. While di-hydroxylated and tri-hydroxylated metabolites were also detected in human plasma to a lesser extent, no meaningful quantitative results could be derived due to the absence of reference standards for these multiple hydroxylated metabolites. The relative activity and significance of these metabolites are not known.

    The elimination half-life of hydroxyprogesterone caproate, as evaluated from 4 patients in the study who reached full-term in their pregnancies, was 16.4 (±3.6) days. The elimination half-life of the mono-hydroxylated metabolites was 19.7 (±6.2) days.

    Distribution: Hydroxyprogesterone caproate binds extensively to plasma proteins including albumin and corticosteroid binding globulins.

    Metabolism: In vitro studies have shown that hydroxyprogesterone caproate can be metabolized by human hepatocytes, both by phase I and phase II reactions. Hydroxyprogesterone caproate undergoes extensive reduction, hydroxylation and conjugation. The conjugated metabolites include sulfated, glucuronidated and acetylated products. In vitro data indicate that the metabolism of hydroxyprogesterone caproate is predominantly mediated by CYP3A4 and CYP3A5. The in vitro data indicate that the caproate group is retained during metabolism of hydroxyprogesterone caproate.

    Excretion: Both conjugated metabolites and free steroids are excreted in the urine and feces, with the conjugated metabolites being prominent. Following intramuscular administration to pregnant women at 10-12 weeks gestation, approximately 50% of a dose was recovered in the feces and approximately 30% recovered in the urine.

    Drug Interactions


    Cytochrome P450 (CYP) enzymes: An in vitro inhibition study using human liver microsomes and CYP isoform-selective substrates indicated that hydroxyprogesterone caproate increased the metabolic rate of CYP1A2, CYP2A6, and CYP2B6 by approximately 80%, 150%, and 80%, respectively. However, in another in vitro study using human hepatocytes under conditions where the prototypical inducers or inhibitors caused the anticipated increases or decreases in CYP enzyme activities, hydroxyprogesterone caproate did not induce or inhibit CYP1A2, CYP2A6, or CYP2B6 activity. Overall, the findings indicate that hydroxyprogesterone caproate has minimal potential for CYP1A2, CYP2A6, and CYP2B6 related drug-drug interactions at the clinically relevantconcentrations.

    In vitro     data indicated that therapeutic concentration of hydroxyprogesterone caproate is not likely to inhibit the activity of CYP2C8, CYP2C9, CYP2C19, CYP2D6, CYP2E1, and CYP3A4.

  • 13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis & Mutagenesis & Impairment Of Fertility

    Hydroxyprogesterone caproate has not been adequately evaluated for carcinogenicity.

    No reproductive or developmental toxicity or impaired fertility was observed in a multigenerational study in rats. Hydroxyprogesterone caproate administered intramuscularly, at gestational exposures up to 5 times the recommended human dose, had no adverse effects on the parental (F0) dams, their developing offspring (F1), or the latter offspring's ability to produce a viable, normal second (F2) generation.

  • 14 CLINICAL STUDIES

    14.1 Clinical Trial to Evaluate Reduction of Risk of Preterm Birth

    In a multicenter, randomized, double-blind, vehicle (placebo)-controlled clinical trial, the safety and effectiveness of Hydroxyprogesterone caproate injection for the reduction of the risk of spontaneous preterm birth was studied in women with a singleton pregnancy (age 16 to 43 years) who had a documented history of  singleton spontaneous preterm birth (defined as delivery at less than 37 weeks of gestation following spontaneous preterm labor or premature rupture of membranes).  At the time of randomization (between 16 weeks, 0 days and 20 weeks, 6 days of gestation), an ultrasound examination had confirmed gestational age and no known fetal anomaly. Women were excluded for prior progesterone treatment or heparin therapy during the current pregnancy, a history of thromboembolic disease, or maternal/obstetrical complications (such as current or planned cerclage, hypertension requiring medication, or a seizure disorder).

    A total of 463 pregnant women were randomized to receive either Hydroxyprogesterone caproate injection (N=310) or vehicle (N=153)  at a dose of 250 mg  administered weekly by intramuscular injection starting between 16 weeks, 0 days  and 20 weeks, 6 days of gestation, and continuing until 37 weeks of gestation or delivery. Demographics of the Hydroxyprogesterone caproate injection-treated women were similar to those in the control group, and included: 59.0% Black, 25.5% Caucasian, 13.9% Hispanic and 0.6% Asian. The mean body mass index was 26.9 kg/m2.
    The proportions of women in each treatment arm who delivered at < 37 (the primary study endpoint), < 35, and < 32 weeks of gestation are displayed in Table 5.

    2 Adjusted for interim analysis.

    Compared to controls , treatment with Hydroxyprogesterone caproate injection reduced the proportion of women who delivered preterm  at < 37 weeks. The proportions of women delivering at < 35 and < 32 weeks also were lower among women treated with Hydroxyprogesterone caproate injection. The upper bounds of the confidence intervals for the treatment difference at < 35 and < 32 weeks were close to zero. Inclusion of zero in a confidence interval would indicate the treatment difference is not statistically significant. Compared to the other gestational ages evaluated, the number of preterm births at < 32 weeks was limited.

    After adjusting for time in the study, 7.5% of Hydroxyprogesterone caproate injection-treated subjects delivered prior to 25 weeks compared to 4.7% of control subjects; see Figure  1.

    A composite neonatal morbidity/mortality index evaluated adverse outcomes in livebirths. It was based on the number of neonates who died or experienced respiratory distress syndrome, bronchopulmonary dysplasia, grade 3 or 4 intraventricular hemorrhage, proven sepsis, or necrotizing enterocolitis. Although the proportion of neonates who experienced 1 or more events was numerically lower in the Hydroxyprogesterone caproate injection arm (11.9% vs. 17.2%), the number of adverse outcomes was limited and the difference between arms was not statistically significant.


    14.2 Infant Follow-Up Safety Study

    Infants born to women enrolled in this study, and who survived to be discharged from the nursery, were eligible for participation in a follow-up safety study. Of 348 eligible offspring, 79.9% enrolled: 194 children of Hydroxyprogesterone caproate injection, USP-treated women and 84 children of control subjects. The primary endpoint was the score on the Ages & Stages Questionnaire (ASQ), which evaluates communication, gross motor, fine motor, problem solving, and personal/social parameters. The proportion of children whose scores met the screening threshold for developmental delay in each developmental domain was similar for each treatment group.

    Hydroxyprogesterone caproate injection
    (hye droks ee proe JES te rone CAP ro ate)

    Read this Patient Information Leaflet before you receive Hydroxyprogesterone caproate injection. There may be new information. This information does not take the place of talking to your healthcare provider about your medical condition or treatment.

    What is Hydroxyprogesterone caproate injection?
    Hydroxyprogesterone caproate injection is a prescription hormone medicine (progestin) used in women who are pregnant and who have delivered a baby too early (preterm) in the past. Hydroxyprogesterone caproate injection is used in these women to help lower the risk of having a preterm baby again. It is not known if Hydroxyprogesterone caproate injection reduces the number of babies who are born with serious medical conditions or die shortly after birth. Hydroxyprogesterone caproate injection is for women who:

    Are pregnant with one baby
    Have had a preterm delivery of one baby in the past

    Hydroxyprogesterone caproate injection is not intended for use to stop active preterm labor.

    It is not known if Hydroxyprogesterone caproate injection is safe and effective in women who have other risk factors for preterm birth.

    Hydroxyprogesterone caproate injection is not for use in women under 16 years of age.

     
    Who should not receive Hydroxyprogesterone caproate injection?

    Hydroxyprogesterone caproate injection should not be used if you have:

    blood clots or other blood clotting problems now or in the past
    breast cancer or other hormone-sensitive cancers now or in the past
    unusual vaginal bleeding not related to your current pregnancy
    yellowing of your skin due to liver problems during your pregnancy
    liver problems, including liver tumors
    high blood pressure that is not controlled
