E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
(1) To assess if luteal phase support in modified natural cycle frozen-thawed embryo transfer (mNC-FET) is superior to no luteal phase support in terms of live birth rates per transfer and
(2) To assess if warming+transfer 6 days after hCG is superior to warming+transfer 7 days after hCG in terms of live birth rates per transfer in mNC-FET. |
|
E.2.2 | Secondary objectives of the trial |
1) To investigate endocrine profiles in blood samples of women undergoing mNC-FET with or without luteal phase progesterone support. 2) To compare treatment outcomes including biochemical and clinical pregnancy rates, miscarriage rates and obstetric complications. 3) To compare neonatal outcomes (way of birth (vaginal birth or caesarean section), indication for caesarean section, use of forceps or cup during birth, sex of child, birth weight and length, gestational age, potential complications during pregnancy and birth, malformations and admission to neonatal intensive care unit). 4) To compare quality of life of women receiving and not receiving luteal phase progesterone support.
|
|
E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
To further explore the effect of luteal progesterone supplementation in mNC-FET a sub group of 80 patients receiving and not receiving vaginal progesterone will have additional blood samples taken twice preovulatory and at five timepoints during the luteal phase, to detect endocrine profiles that may or may not be compatible with conception. Study subjects for the sub-study analyses will be included consecutively at only two clinics; Rigshospitalet, Copenhagen University Hospital and Horsens Regional Hospital, until the goal of 40 patients in each of the two study groups +/- vaginal progesterone is met. |
|
E.3 | Principal inclusion criteria |
Inclusion criteria Female age 18-41 years Regular menstrual cycle (23-35 days) Vitrified blastocysts derived from 1.-3. IVF/ICSI cycle resulting in an embryo transfer in a public hospital Undergoing single blastocyst transfer.
|
|
E.4 | Principal exclusion criteria |
Previous participation in the study, uterine malformations, intrauterine polyps or submucosal myomas, breast feeding, oocyte donation, preimplantation genetic testing, blastocyst conceived with sperm from testicular sperm aspiration, HIV (woman), hepatitis B and C (woman), known luteal phase insufficiency or if patients are not fulfilling the inclusion criteria. Further exclusion criteria are the following contraindications to progesterone; allergy to the study medication, undiagnosed vaginal bleeding, current missed abortion or ectopic pregnancy, hepatic insufficiency or severe hepatic disease, genital or breast cancer, arterial or venous thromboembolism, thrombophlebitis or porphyria. For patients participating in the sub-study, thyroid disease is an exclusion criterion. |
|
E.5 End points |
E.5.1 | Primary end point(s) |
1) A 10% increase in live birth rate in the groups receiving luteal phase progesterone support compared to the groups not receiving luteal phase progesterone support. 2) A 10% increase in live birth in the groups undergoing frozen embryo transfer day six following ovulation trigger compared to day seven following ovulation trigger. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
6 years from start of inclusion, 1 year after last patient is recruited. |
|
E.5.2 | Secondary end point(s) |
Additional endpoints include assessment of other relevant aspects of mNC-FET including chemical and clinical pregnancy rates, miscarriage rates and obstetric and neonatal outcomes in the study groups. Furthermore, endocrine blood samples will be collected in all study groups to determine if an endocrine profile compatible and not compatible with conception, can be identified. Lastly, quality of life questionnaires, from patients receiving and not receiving vaginal luteal phase support will be compared, having patient wellbeing as a focus point. |
