Summary

Patients who have been previously surgically diagnosed with endometriosis and have embryos predicted to be euploid after in vitro fertilization will be divided into 2 groups via randomization. The test group will receive Elagolix for 60 days prior to starting frozen embryo transfer preparation. The control group will be given leuprolide acetate every 28 days x 2 prior to starting the frozen embryo transfer preparation.

Comparative implantation rates between two groups of patients will be evaluated

Description

  1. Baseline visit prior to initiation of IVF cycle:

Review nature of study, confirm surgical diagnosis of endometriosis, obtain informed consent, confirm absence of exclusion criteria

2. Standard IVF and preimplantation genetic screening (prior to study entry):

Subjects will undergo standard ovarian stimulation, monitoring (serum and ultrasound), oocyte aspiration, in vitro fertilization (IVF), intracytoplasmic sperm injection (ICSI), embryo culture to the blastocyst stage of development, trophectoderm biopsy, comprehensive chromosomal screening of embryos (CCS) and embryo vitrification as per protocols of CCRM and as determined by the primary CCRM physician.

3. Initial study entry visit performed within 4 weeks of initial medication administration after confirmation of presence of euploid embryo(s): Complete blood count, chemistry, renal and liver function panels. Computer generated randomization Obtain serum sample for micro RNA evaluation (results will not impact treatment and will only be analyzed retrospectively) Cycle Day2-4 serum FSH, estradiol, LH, progesterone, hCG level and transvaginal ultrasound examination to evaluate endometrial lining and the presence/absence of ovarian cysts All patients will be instructed to avoid pregnancy through use of barrier contraception while on study drug

4. Initial dosing Once screening evaluation has been cleared by the investigator, subject will be administered Lupron Depot 3.75 mg intramuscularly on cycle day 2-6 or will self-administer elagolix 200 mg orally twice daily beginning 2-6

5. Week 4 (30 days after initial dosing) Subjects will have repeat FSH, estradiol, LH, progesterone, and hCG levels drawn Subjects will be interviewed by study coordinator regarding presence or absence adverse outcomes/side effects including incidence and severity of hot flushes, vaginal bleeding, headache, nausea and vomiting Unless subject wishes to discontinue trial or is experiencing significant adverse events necessitating drop-out, patients in Lupron group will receive a second dose of Lupron Depot 3.75 mg intramuscularly and those in the elagolix dose will continue 200 mg twice daily oral dosing for an additional 30 days which will be dispensed at this visit

6. Week 8 (60 days after initial dosing) Subjects will have repeat FSH, estradiol, LH, progesterone and hCG levels as well as CBC and chem panel including liver function tests drawn Serum sample will be obtained for follow-up microarray analysis Transvaginal ultrasound examination will be performed to evaluate endometrial thickness and presence/absence of ovarian cysts Interview with study coordinator regarding presence/absence of adverse events/ side effects as described above

7. First menses after completion of study drug/ Endometrial preparation for embryo transfer Initiation of standard endometrial preparation with exogenous trans-dermal estradiol in conjunction with oral and/or intramuscular preparations per standard CCRM protocols and as determined by the primary physician to achieve an endometrial thickness of 7.0-15.0 mm with a trilaminar pattern. Standard monitoring with serial ultrasound examination and assessment of serial estradiol, LH and progesterone levels will be performed per CCRM protocols. Once appropriate endometrial development has been achieved after a minimum of 10 days of preparation, both intravaginal and intramuscular progesterone will be added to the estradiol with planned embryo transfer on the sixth day of progesterone administration

8. Embryo transfer Vitrified euploid embryo(s) selected for transfer will be warmed on the day of transfer which will be performed under ultrasound guidance using standard CCRM protocols. No more than 2 euploid embryos may be transferred and all patients will be encouraged to undergo a single transfer. Indication for a two embryo transfer will be documented. Best quality embryo(s) will be transferred preferentially choosing day 5 euploid blastocysts over day 6 or 7 euploid blastocysts. Embryos will be graded using the classification system of Gardner et al. (see reference section)

9. Luteal support Subjects will receive standard luteal support with both injectable and intravaginal progesterone with doses adjusted per CCRM guidelines.

10. Pregnancy diagnosis and monitoring Subjects will have an initial serum hCG level obtained 9 days after embryo transfer in their local clinic. Estradiol and progesterone levels will also be measured if hCG is positive. Repeat hCG level will obtained two days after the first level if the first level was positive. First pregnancy ultrasound will be obtained 2-2.5 weeks after initial positive hCG level unless there is a clinical indication for an earlier evaluation. If all is normal with first pregnancy ultrasound examination, a second ultrasound examination to evaluate pregnancy will be performed 2-2.5 weeks thereafter unless clinical circumstances require earlier evaluation. Progesterone and estradiol supplementation will typically be tapered using CCRM guidelines beginning at 10 weeks of pregnancy and be discontinued entirely no later than the end of the 13th week of pregnancy. Subjects will be referred to their primary obstetricians after the second pregnancy ultrasound examination at 8 weeks of pregnancy

11. Pregnancy outcome data collection The outcomes of all pregnancies shall be obtained from the patient and recorded. If live birth, all data required by Center for Disease Control will be collected including gestational age, birth weight, immediately diagnosed anomalies and pregnancy complications. The gestational age, management, and pathology reports (if available) from pregnancy loss, ectopic pregnancy and still birth shall also be collected.

Any pregnancies that occur while on study drugs or which occur after completion of the drugs but prior to embryo transfer will be recorded and monitored in the same fashion as described above
