REMODEL: Oral Versus Vaginal Progesterone for Luteal Phase Supplementation in Frozen Embryo Transfer Cycles
Study Details
Study Description
Brief Summary
To investigate the efficacy of dydrogesterone 30 mg compared to micronized vaginal progesterone 800 mg daily for luteal phase support in hormone replacement therapy frozen embryo transfer cycles, as confirmed by visualization of fetal heart activity by pelvic ultrasound assessment of ongoing pregnancy at 12 weeks of gestation.

Phase 4 |
Detailed Description
A randomized controlled trial comparing dydrogesterone 30 mg versus micronized vaginal progesterone 800 mg daily for luteal phase support in hormone replacement therapy frozen embryo transfer cycles. Patients will undergo an embryo transfer in a hormone replacement therapy cycle using Progynova 2 mg three times daily until an endometrium thickness of at least 7 mm is reached. Afterwards two different luteal phase supplementation methods will be compared. The primary outcome of the study is ongoing pregnancy at 12 weeks of gestation. We will also investigate other prenatal and neonatal outcome factors as well as patients satisfaction and safety of dydrogesterone.

Outcome Measures
Primary Outcome Measures
- Ongoing pregnancy [12 weeks]
visualisation of a fetal heart activity via pelvic (vaginal/abdominal) ultrasound examination at 12 weeks of gestation.
Secondary Outcome Measures
- Live birth rate [22-42 weeks]
as the birth of a live newborn after 22 weeks of gestation
- Time of delivery [follow-up time of 30 days after delivery]
time of delivery (gestational week) will be confirmed (by calculation from date of embryo transfer)
- Incidence of Treatment-Emergent Adverse Events [follow-up time of 30 days after delivery]
Tolerability and safety will be asses during the whole study period. Adverse events will be considered as unexpected if the nature, seriousness, severity or outcome of the reaction(s) is not consistent with the reference information. The expectedness of adverse events for the medications used in this study is detailed in the reference safety information in the current summary of product characteristics (SmPCs) issued in the participating countries. All serieus suspected unexpected serious adverse drug reactions (SUSARs) will be subject to expedited reporting. The investigator is responsible for submitting reports of SUSARs to the appropriate national regulatory authorities within the required reporting period. The investigator is responsible for notifying the IECs/IRBs in writing of the SUSARs within the required reporting timelines. Copies of the notification will be maintained by the investigator in the study documentation files.
- Patient reported outcome [day 12-18 of luteal phase supplementation (pregnancy test) and at 12 weeks gestation]
Questionnaire (using the Treatment Satisfaction Questionnaire of Medication (TSQM)) and recording information on treatment tolerability and convenience
- Incidence of newborn adverse events [follow-up time of 30 days after delivery]
Newborn wellbeing and safety including congenital malformations will be evaluated after delivery via a telephonic contact with the patient
- Biochemical pregnancy rate [day 12-18 of luteal phase supplementation (pregnancy test)]
serum hCG test (> 25 mIU/ml), without ultrasound evaluation of a pregnancy
- Clinical pregnancy rate [Day 33-39 of LPS (Verification of pregnancy)]
assessed by transvaginal ultrasound and defined as the presence of ≥1 gestational sac on examination
- Miscarriage rate [22 weeks]
defined as spontaneous loss of a clinical pregnancy before 22 weeks of gestation (where embryo(s) or fetus(es) is/are nonviable and is/are not spontaneously absorbed or expelled from the uterus)
- Rate of preterm birth [follow-up time of 30 days after delivery]
Delivery before 37 weeks of gestation
- Rate of pre-eclampsia [follow-up time of 30 days after delivery]
Incidence of pre-eclampsia as defined by the defined as the development of hypertension after 20 weeks of gestation together with one or more new-onset conditions: proteinuria, maternal or uteroplacental dysfunctions. Univariate and multivariable regression analysis were performed to control for known or potential PE risk factors, more specifically: body mass index (BMI), African ethnicity, previous history of hypertensive disorders of pregnancy, mean arterial pressure (MAP) at the first prenatal consultation, polycystic ovary syndrome (PCOS) and ovulation disorders, endometrial thickness and oocyte recipients.
- Occurence of antenatal bleeding, ultrasonographic abnormalities, gestational diabetes, cholestasis [follow-up time of 30 days after delivery]
Occurence of antenatal bleeding, ultrasonographic abnormalities, gestational diabetes, cholestasis
- Implantation rate [Day 33-39 of LPS (Verification of pregnancy)]
assessed by ultrasound and defined as the number of gestational sacs per number of embryos transferred
- Blastocyst development score [at the time of embryo transfer (visit 2: day 6 of luteal phase supplementation)]
using the system developed by Gardner
- Number of cryopreserved embryos [day of screening and enrollment]
Number of cryopreserved embryos
- Summary characteristics of the preceding controlled ovarian stimulation cycle [day of screening and enrollment]
information on used stimulation medication, total dose of stimulation medication used, duration of stimulation medication, trigger medication
