Clinical Trial 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.

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

Type	Measure	Description	Time frame	Safety issue
Primary	Ongoing pregnancy	visualisation of a fetal heart activity via pelvic (vaginal/abdominal) ultrasound examination at 12 weeks of gestation.	12 weeks
Secondary	Live birth rate	as the birth of a live newborn after 22 weeks of gestation	22-42 weeks
Secondary	Time of delivery	time of delivery (gestational week) will be confirmed (by calculation from date of embryo transfer)	follow-up time of 30 days after delivery
Secondary	Incidence of Treatment-Emergent Adverse Events	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.	follow-up time of 30 days after delivery
Secondary	Patient reported outcome	Questionnaire (using the Treatment Satisfaction Questionnaire of Medication (TSQM)) and recording information on treatment tolerability and convenience	day 12-18 of luteal phase supplementation (pregnancy test) and at 12 weeks gestation
Secondary	Incidence of newborn adverse events	Newborn wellbeing and safety including congenital malformations will be evaluated after delivery via a telephonic contact with the patient	follow-up time of 30 days after delivery
Secondary	Biochemical pregnancy rate	serum hCG test (> 25 mIU/ml), without ultrasound evaluation of a pregnancy	day 12-18 of luteal phase supplementation (pregnancy test)
Secondary	Clinical pregnancy rate	assessed by transvaginal ultrasound and defined as the presence of =1 gestational sac on examination	Day 33-39 of LPS (Verification of pregnancy)
