8.1 Pregnancy

ENDOMETRIN has been used to support embryo implantation and maintain clinical pregnancy in one clinical study. The live birth outcomes of these pregnancies were as follows:
- Among the 404 subjects treated with ENDOMETRIN twice daily, 143 subjects had live births consisting of 85 singletons, 56 twins, and 2 triplets. In this treatment group, 13 subjects had a spontaneous abortion, 1 subject had an ectopic pregnancy, and 7 subjects reported fetal birth defects (3.4% based on 203 livebirths).
- Among the 404 subjects treated with ENDOMETRIN three times daily, 155 subjects had livebirths consisting of 91 singletons, 60 twins, and 4 triplets. In this treatment group, 22 subjects had a spontaneous abortion, 4 subjects had an ectopic pregnancy, and 7 subjects reported fetal birth defects (3.1% based on 223 livebirths).
Birth defects reported in the ENDOMETRIN twice daily group included: one fetus with a cleft palate and intrauterine growth retardation, one fetus with spina bifida, three fetuses with congenital heart defects, one fetus with an umbilical hernia, and one fetus with an intestinal anomaly.

Birth defects reported in the ENDOMETRIN three times daily group included: one fetus with an esophageal fistula, one fetus with hypospadias and an underdeveloped right ear, one fetus with Down Syndrome and an atrial septal defect, one fetus with congenital heart anomalies, one fetus with DiGeorge's syndrome, one fetus with a hand deformity, and one fetus with cleft palate.

For additional information on the pharmacology of ENDOMETRIN and pregnancy outcome information [ see Clinical Pharmacology (12) and Clinical Studies Sections (14)].

12.1 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.

12.3 Pharmacokinetics

Absorption

Progesterone serum concentrations increased following the administration of the ENDOMETRIN Vaginal Insert in 12 healthy pre-menopausal females. On single dosing, the mean Cmax was 17.0 ng/mL in the ENDOMETRIN twice daily group and 19.8 ng/mL in the ENDOMETRIN three times daily group. On multiple dosing, steady-state concentrations were attained within approximately 1 day after initiation of treatment with ENDOMETRIN. Both ENDOMETRIN regimens provided average serum concentrations of progesterone exceeding 10 ng/mL on Day 5. The pharmacokinetic results are summarized in Table 2.

AUC0-24 (ng∙hr/mL)	327 ± 127	436 ± 106

Distribution

Progesterone is approximately 96% to 99% bound to serum proteins, primarily to serum albumin and corticosteroid binding globulin.

Metabolism

Progesterone is metabolized primarily by the liver, largely to pregnanediols and pregnanolones. Pregnanediols and pregnanolones are conjugated in the liver to glucuronide and sulfate metabolites. Progesterone metabolites that are excreted in the bile may be deconjugated and may be further metabolized in the gut via reduction, dehydroxylation, and epimerization.

Excretion

Progesterone undergoes renal and biliary elimination. Following 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 a small portion of unchanged progesterone is excreted in the bile.

14.1 Luteal Supplementation During Assisted Reproductive Treatment Study

A randomized, open-label, active-controlled study evaluated the efficacy of 10 weeks of treatment with two different daily dosing regimens of ENDOMETRIN (100 mg twice daily and 100 mg three times daily) for support of implantation and early pregnancy in infertile women participating in an Assisted Reproductive Technology treatment program. Efficacy was assessed on the endpoint of ongoing pregnancies, defined as the presence of at least one fetal heartbeat seen on ultrasound at 6 weeks post-embryo transfer. The study randomized to ENDOMETRIN 808 infertile women (74.9% White; 10.3% Hispanic, 5.4% Black, 5% Asian, and 4.6% Other) between 19 and 42 years of age (mean age 33) who had a body mass index <34 kg/m2 at screening.

The ongoing pregnancy rates for subjects treated with both dosing regimens of ENDOMETRIN were non-inferior (lower bounds of the 95% confidence interval of the difference between ENDOMETRIN and the active comparator excluded a difference greater than 10%) to the ongoing pregnancy rate for subjects treated with the active comparator. The results of this study are shown in Table 3.

Pregnancy rate percentage difference between ENDOMETRIN and comparator	-12.2%	-7.7%
95% Confidence Interval for difference vs. comparator	[-31.0, 7.7]	[-26.6, 11.6]

In subjects under the age of 35 or with serum FSH levels less than 10 IU/L, results from both dosing regimens were non-inferior to the results from the comparator with respect to ongoing pregnancy rates. In women age 35 and older and in women with serum FSH levels between 10 and 15 IU/L, the results with respect to ongoing pregnancy rates for both dosing regimens of ENDOMETRIN did not reach the criteria for non-inferiority.

Subjects who became pregnant received study medication for a total of 10 weeks. Patients over 34 kg/m2 were not studied. The efficacy of ENDOMETRIN in this patient group is unknown.
