Overview
Hydroxyprogesterone caproate is a progestin that is FDA approved for the treatment of indicated to reduce the risk of preterm birth in women with a singleton pregnancy who have a history of singleton spontaneous preterm birth.. Common adverse reactions include injection site reactions, paiN, swelling [17%], pruritus [6%], nodule [5%]), urticaria (12%), nausea (6%), and diarrhea (2%)..
Adult Indications and Dosage
FDA-Labeled Indications and Dosage (Adult)
Used 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 Makena 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 Makena 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.
Dosage
Administer intramuscularly at a dose of 250 mg (1 mL) once weekly (every 7 days) 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.

Warnings
Thromboembolic Disorders
Discontinue Makena if an arterial or deep venous thrombotic or thromboembolic event occurs.
Allergic Reactions
Allergic reactions, including urticaria,pruritus and angioedema, have been reported with use of Makena or with other products containing castor oil. Consider discontinuing the drug if such reactions occur.
Decrease in Glucose Tolerance
A decrease in glucose tolerance has been observed in some patients on progestin treatment. The mechanism of this decrease is not known. Carefully monitor prediabetic and diabetic women while they are receiving Makena.
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).
Depression
Monitor women who have a history of clinical depression and discontinue Makena if clinical depression recurs.
Jaundice
Carefully monitor women who develop jaundice while receiving Makena and consider whether the benefit of use warrants continuation.
Hypertension
Carefully monitor women who develop hypertension while receiving Makena and consider whether the benefit of use warrants continuation.
Adverse Reactions
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 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 preterm delivery based on obstetrical history, 310 received 250 mg of Makena 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.
Certain pregnancy-related fetal and maternal complications or events were numerically increased in the Makena-treated subjects as compared to control subjects, including miscarriage and stillbirth, admission for preterm labor, preeclampsia or gestational hypertension, gestational diabetes, and oligohydramnios.
1 N = Total number of subjects enrolled prior to 20 weeks 0 days 2 N = Total number of subjects at risk ≥ 20 weeks
Common Adverse Reactions
The most common adverse reaction was injection site pain, which was reported after at least one injection by 34.8% of the Makena group and 32.7% of the control group. Table 3 lists adverse reactions that occurred in ≥2% of subjects and at a higher rate in the Makena group than in the control group.
In the clinical trial, 2.2% of subjects receiving Makena were reported as discontinuing therapy due to adverse reactions compared to 2.6% of control subjects. The most common adverse reactions that led to discontinuation 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 Makena-treated subjects.
Postmarketing Experience
The following adverse reactions have been identified during postapproval use of Makena. 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
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 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.
Use in Specific Populations
Pregnancy
Pregnancy Category (FDA): B There are no adequate and well-controlled studies of Makena use in women during the first trimester of pregnancy. Data from a vehicle (placebo)-controlled clinical trial of 310 pregnant women who received Makena at weekly doses of 250 mg by intramuscular injection in their second and third trimesters1, as well as long-term (2-5 years) follow-up safety data on 194 of their infants 2, did not demonstrate any teratogenic risks to infants from in utero exposure to Makena.
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 Makena.
Makena administration produced embryolethality in rhesus monkeys but not in cynomolgus monkeys exposed to 1 and 10 times the human dose equivalent every 7 days between days 20 and 146 of gestation. There were no teratogenic effects in either species.
Pregnancy Category (AUS):
There is no Australian Drug Evaluation Committee (ADEC) guidance on usage of Hydroxyprogesterone caproate in women who are pregnant.
Labor and Delivery
Makena is not intended for use to stop active preterm labor. The effect of Makena in active labor is unknown.
Nursing Mothers
Discontinue Makena at 37 weeks of gestation or upon delivery. Detectable amounts of progestins have been identified in the milk of mothers receiving progestin treatment. Many studies have found no adverse effects of progestins on breastfeeding performance, or on the health, growth, or development of the infant
Pediatric Use
Makena is not indicated for use in children. 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.
Geriatic Use
Makena is not intended for use in postmenopausal women. Safety and effectiveness in postmenopausal women have not been established.
Gender
There is no FDA guidance on the use of Hydroxyprogesterone caproate with respect to specific gender populations.
Race
There is no FDA guidance on the use of Hydroxyprogesterone caproate with respect to specific racial populations.
Renal Impairment
No studies have been conducted to examine the pharmacokinetics of Makena in patients with renal impairment.
Hepatic Impairment
No studies have been conducted to examine the pharmacokinetics of Makena in patients with hepatic impairment. Makena is extensively metabolized and hepatic impairment may reduce the elimination of Makena.
Females of Reproductive Potential and Males
There is no FDA guidance on the use of Hydroxyprogesterone caproate in women of reproductive potentials and males.
Immunocompromised Patients
There is no FDA guidance one the use of Hydroxyprogesterone caproate in patients who are immunocompromised.
Administration and Monitoring
Administration
Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Makena is a clear, yellow solution. Do not use if solid particles appear or if the solution is cloudy.
Instructions for administration
Clean the vial top with an alcohol swab before use. Draw up 1 mL of drug into a 3 mL syringe with an 18 gauge needle. Change the needle to a 21 gauge 1 1/2 inch needle. 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. Applying pressure to the injection site may minimize bruising and swelling. Discard any unused product 5 weeks after first use.
Monitoring
There is limited information regarding Hydroxyprogesterone caproate Monitoring in the drug label.
IV Compatibility

Pharmacology
Mechanism of Action
Hydroxyprogesterone caproate is a synthetic progestin. The mechanism by which hydroxyprogesterone caproate reduces the risk recurrent preterm birth is not known.
Structure
There is limited information regarding Hydroxyprogesterone caproate Structure in the drug label.
Pharmacodynamics
No specific pharmacodynamic studies were conducted with Makena.
Pharmacokinetics
Absorption: Peak serum levels of hydroxyprogesterone caproate appeared after 3-7 days in non-pregnant female subjects following a single intramuscular injection of 1000 mg hydroxyprogesterone caproate. Based on pharmacokinetic analysis of five non-pregnant female subjects who received a single intramuscular administration of 1000 mg hydroxyprogesterone caproate, the mean (±SD) Cmax is estimated to be 27.8 (±5.3) ng/mL, and the Tmax is estimated to be 4.6 (±1.7) days. The elimination half-life of hydroxyprogesterone caproate was 7.8 (±3.0) days. Once-weekly intramuscular administration of 1000 mg hydroxyprogesterone caproate to non-pregnant women resulted in trough concentration of 60.0 (±14) ng/mL after 13 weeks. The pharmacokinetics of the 250 mg dose of hydroxyprogesterone caproate has not been evaluated.
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.
Nonclinical Toxicology
There is limited information regarding Hydroxyprogesterone caproate Nonclinical Toxicology in the drug label.
Clinical Studies
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 Makena 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).1 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 Makena (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 Makena-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 4.
1 Four Makena-treated subjects were lost to follow-up. They were counted as deliveries at their gestational ages at time of last contact (184, 220, 343 and 364 weeks). 2 Adjusted for interim analysis.
Table 4 Proportion of Subjects Delivering at < 37, < 35 and < 32 Weeks Gestational Age (ITT Population) Compared to controls, treatment with Makena 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 Makena. 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 Makena-treated subjects delivered prior to 25 weeks compared to 4.7% of control subjects; see Figure 1.
Figure 1 Proportion of Women Remaining Pregnant as a Function of Gestational Age
The rates of fetal and neonatal deaths in each treatment arm are displayed in Table 5. Due to the higher rate of miscarriages and stillbirths in the Makena arm, there was no overall survival difference demonstrated in this clinical trial.
A Four of the 310 Makena-treated subjects were lost to follow-up and stillbirth or neonatal status could not be determined B Percentages are based on the number of enrolled subjects and not adjusted for time on drug C Percentage adjusted for the number of at risk subjects (n=209 for Makena, n=107 for control) enrolled at <20 weeks gestation. 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 Makena 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 Makena-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.2

Patient Information
Makena (mah-KEE-na) (hydroxyprogesterone caproate injection) 250 mg/mL
Read this Patient Information Leaflet before you receive Makena. 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 Makena?
Makena is a prescription hormone medicine (progestin) used in women who are pregnant and who have delivered a baby too early (preterm) in the past. Makena is used in these women to help lower the risk of having a preterm baby again.
Makena is for women who:
Are pregnant with one baby Have had a preterm delivery of one baby in the past How well does Makena work?
Makena was studied in women who were at risk for having a preterm baby because they had previously given birth to a preterm baby. In the main study, about 37 of 100 women who received Makena gave birth preterm (before 37 weeks of pregnancy), compared to about 55 of 100 women who did not receive Makena. Another study of Makena is going on to see whether Makena reduces the number of babies who have serious problems shortly after birth or who die.
It is not known whether Makena is safe and effective in women who have other risk factors for preterm birth.
It is not known whether Makena is safe and effective in women less than 16 years old.
Makena is not intended for use to stop active preterm labor.
Who should not receive Makena?
Makena should not be used if you:
Have now or have had a history of blood clots or other blood clotting problems Have now or have had a history of breast cancer or other hormone-sensitive cancers Have unusual vaginal bleeding not related to your current pregnancy Have yellowing of your skin due to liver problems during your pregnancy Have liver problems, including liver tumors Have uncontrolled high blood pressure What should I tell my healthcare provider before receiving Makena?
