The purpose of this study is to evaluate safety and performance of Vitrolife´s new oocyte
vitrification/warming media and the vitrification device Rapid-i™, when using vitrification
as a cryopreservation method for human oocytes.
|
| Study Summary: |
|
A multi-center prospective sibling oocyte vitrification trial where, in the first phase,
half of the patients' oocytes will be vitrified and warmed (experimental group). The
remaining oocytes will not be vitrified and will serve as the control group. In the second
phase all of the patients' oocytes will be vitrified and the embryo transfer will be
performed in a following cycle. This simulates the situation of a normal cryopreservation
embryo transfer. The study population consists of 20 women who will undergo a fresh IVF
cycle during the study period. The primary objective in the first phase is to assess
survival, fertilization and embryo development after oocyte vitrification/warming with the
new media. The results will be compared with results from sibling oocytes which have not
been vitrified. Secondary objectives are to assess the clinical results such as
implantation, miscarriage and pregnancy rate as well as delivery rate and neonatal outcome.
The primary objective in the second phase is to assess the delivery rate after oocyte
vitrification/warming with the new media. Secondary objectives are to assess survival,
fertilization, embryo development, utilization rate, pregnancy rate and neonatal outcome on
the previously vitrified and warmed oocytes. The results will be compared with results from
a control group of patients, treated at the same clinics within the same time period, using
the same inclusion and exclusion criteria. All patients who undergo embryo transfer will
have a serum beta-hCG test conducted 14 days after oocyte retrieval. If positive, repeat
beta-hCG testing will be conducted 2-4 days later. If appropriate, a pregnancy ultrasound
will be conducted between 6-8 weeks gestation (menstrual age) to record gestational sac(s)
and fetal heart beat. The delivery outcome will also be recorded. For patients with an
unsuccessful treatment, there will be a follow-up period of 6 months after study completion.
From this follow-up, data from frozen cycles, i.e. from embryos after oocyte vitrification,
can be evaluated as well.
