1 INDICATIONS AND USAGE

Progesterone Retard Pharlon 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 Progesterone Retard Pharlon 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 Progesterone Retard Pharlon 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.

6.1 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 Progesterone Retard Pharlon 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.¹

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 (Tables 1 and 2).

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 Progesterone Retard Pharlon 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 Progesterone Retard Pharlon group than in the control group.

In the clinical trial, 2.2% of subjects receiving Progesterone Retard Pharlon 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.

6.2 Postmarketing Experience

The following adverse reactions have been identified during postapproval use of Progesterone Retard Pharlon. 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 Progesterone Retard Pharlon. No in vivo drug-drug interaction studies were conducted with Progesterone Retard Pharlon.

8 USE IN SPECIFIC POPULATIONS

Pregnancy: Controlled studies show no increase in congenital anomalies, including genital abnormalities in male or female infants, from exposure during pregnancy to Progesterone Retard Pharlon.

8.1 Pregnancy

Pregnancy Category B: There are no adequate and well-controlled studies of Progesterone Retard Pharlon use in women during the first trimester of pregnancy. Data from a vehicle (placebo)-controlled clinical trial of 310 pregnant women who received Progesterone Retard Pharlon 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 Progesterone Retard Pharlon.

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 Progesterone Retard Pharlon.

Progesterone Retard Pharlon 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.

8.2 Labor and Delivery

Progesterone Retard Pharlon is not intended for use to stop active preterm labor. The effect of Progesterone Retard Pharlon in active labor is unknown.

8.3 Nursing Mothers

Discontinue Progesterone Retard Pharlon 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.

8.4 Pediatric Use

Progesterone Retard Pharlon 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.

8.5 Geriatric Use

Progesterone Retard Pharlon is not intended for use in postmenopausal women. Safety and effectiveness in postmenopausal women have not been established.

8.6 Renal Impairment

No studies have been conducted to examine the pharmacokinetics of Progesterone Retard Pharlon in patients with renal impairment.

8.7 Hepatic Impairment

No studies have been conducted to examine the pharmacokinetics of Progesterone Retard Pharlon in patients with hepatic impairment. Progesterone Retard Pharlon is extensively metabolized and hepatic impairment may reduce the elimination of Progesterone Retard Pharlon.

10 OVERDOSAGE

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

Chemical Structure for Progesterone Retard Pharlon

12 CLINICAL PHARMACOLOGY

12.1 Mechanism of Action

Progesterone Retard Pharlon is a synthetic progestin. The mechanism by which Progesterone Retard Pharlon reduces the risk of recurrent preterm birth is not known.

12.2 Pharmacodynamics

No specific pharmacodynamic studies were conducted with Progesterone Retard Pharlon.

12.3 Pharmacokinetics

Absorption: Female patients with a singleton pregnancy received intramuscular doses of 250 mg Progesterone Retard Pharlon for the reduction of preterm birth starting between 16 weeks 0 days and 20 weeks 6 days. All patients had blood drawn daily for 7 days to evaluate pharmacokinetics.

For all three groups, peak concentration (C_max) and area under the curve (AUC_{(1-7 days)}) of the mono-hydroxylated metabolites were approximately 3-8-fold lower than the respective parameters for the parent drug, Progesterone Retard Pharlon. 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 Progesterone Retard Pharlon, 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: Progesterone Retard Pharlon binds extensively to plasma proteins including albumin and corticosteroid binding globulins.

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

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.

Specific Populations

Renal Impairment: The effect of renal impairment on the pharmacokinetics of Progesterone Retard Pharlon has not been evaluated.

Hepatic Impairment: The effect of hepatic impairment on the pharmacokinetics of Progesterone Retard Pharlon has not been evaluated.

Drug Interactions

Cytochrome P450 (CYP) enzymes: An in vitro inhibition study using human liver microsomes and CYP isoform-selective substrates indicated that Progesterone Retard Pharlon 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, Progesterone Retard Pharlon did not induce or inhibit CYP1A2, CYP2A6, or CYP2B6 activity. Overall, the findings indicate that Progesterone Retard Pharlon 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 Progesterone Retard Pharlon 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

Progesterone Retard Pharlon has not been adequately evaluated for carcinogenicity.

No reproductive or developmental toxicity or impaired fertility was observed in a multigenerational study in rats. Progesterone Retard Pharlon 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 -controlled clinical trial, the safety and effectiveness of Progesterone Retard Pharlon 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 Progesterone Retard Pharlon (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 5.

Compared to controls, treatment with Progesterone Retard Pharlon 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 Progesterone Retard Pharlon. 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 losses and neonatal deaths in each treatment arm are displayed in Table 6. Due to the higher rate of miscarriages and stillbirths in the Progesterone Retard Pharlon arm, there was no overall survival difference demonstrated in this clinical trial.

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 Progesterone Retard Pharlon arm (11.9% vs. 17.2%), the number of adverse outcomes was limited and thedifference between arms was not statistically significant.

Figure 1 Proportion of Women Remaining Pregnant as a Function of Gestational Age

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

What is Progesterone Retard Pharlon?

Progesterone Retard Pharlon is a prescription hormone medicine (progestin) used in women who are pregnant and who have delivered a baby too early (preterm) in the past. Progesterone Retard Pharlon is used in these women to help lower the risk of having a preterm baby again.

Progesterone Retard Pharlon is for women who:

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

How well does Progesterone Retard Pharlon work?

Progesterone Retard Pharlon 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 Progesterone Retard Pharlon gave birth preterm (before 37 weeks of pregnancy), compared to about 55 of 100 women who did not receive Progesterone Retard Pharlon. Another study of Progesterone Retard Pharlon is going on to see whether Progesterone Retard Pharlon reduces the number of babies who have serious problems shortly after birth or who die.

It is not known whether Progesterone Retard Pharlon is safe and effective in women who have other risk factors for preterm birth.

It is not known whether Progesterone Retard Pharlon is safe and effective in women less than 16 years old.

Progesterone Retard Pharlon is not intended for use to stop active preterm labor.

Who should not receive Progesterone Retard Pharlon?
