About this study

Official title: The Application of Zishen Yutai Pill in Aged Women Undergoing in Vitro Fertilization-embryo Transfer: a Multi-center Double-blind Randomized Controlled Trial

To explore the application of Zishen Yutai Pill in controlled ovarian stimulation and effect on pregnancy outcome in aged women undergoing in vitro fertilization-embryo transfer.

Read the detailed description

This will be a multi-center double-blind randomized controlled trial, which aims to explore the application of Zishen Yutai Pill in controlled ovarian stimulation and effect on pregnancy outcome in aged women undergoing in vitro fertilization-embryo transfer.The target population will be infertile women aged between 35 and 42 years, BMI<28kg/m2 and bilateral ovaries who undergo IVF-ET (long or antagonist protocol). Qualified 1,466 patients are randomized into either of two groups.They will be randomized to receive either Zishen Yutai Pill or the placebo. The pregnancy test results and pregnancy complications will be followed up by checking medical records and telephone calls.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Zishen Yutai PillDrug

    Patients who undergo the long-term protocol will start taking Zishen Yutai Pill on the day of pituitary suppression, 5g three times a day (Stopping on the first 1-4 days of menstruation), and patients who undergo the antagonist protocol will start taking Zishen Yutai Pill on the 19th to 23rd day of the previous menstruation cycle, 5g three times a day (Stopping on the first 1-4 days of menstruation). The drug will be taken till 2 weeks after transplantation. If the test result is confirmed as biochemical pregnancy (HCG>50 IU/L), patients continue to take pills till 3 weeks after the clinical pregnancy determined by the ultrasound. If it is determined that the pregnancy test is negative, stop the drug.

  • PlaceboDrug

    Patients who undergo the long-term protocol will start taking Placebo on the day of pituitary suppression, 5g three times a day (Stopping on the first 1-4 days of menstruation), and patients who undergo the antagonist protocol will start taking Placebo on the 19th to 23rd day of the previous menstruation cycle, 5g three times a day (Stopping on the first 1-4 days of menstruation). The drug will be taken till 2 weeks after transplantation. If the test result is confirmed as biochemical pregnancy (HCG>50 IU/L), patients continue to take pills till 3 weeks after the clinical pregnancy determined by the ultrasound. If it is determined that the pregnancy test is negative, stop the drug.

  13. Clinical Pregnancy Rate

    The clinical pregnancy determined by the ultrasound, and Clinical pregnancy rate=Number of clinical pregnancies / Paticipants randomized

    Measured: five weeks after ET day, approximately 11 weeks

  15. Miscarriage Rate (Among Clinical Pregnancy Population)

    Miscarriage rate (among clinical pregnancy population)=Number of miscarriages / Number of clinical pregnancies

    Measured: 1 year after embryo transfer, up to 58 weeks

  16. The Birth Weight of the Newborn

    By checking medical records

    Measured: 1 year after embryo transfer, up to 58 weeks

    By checking medical records

    Measured: 1 year after embryo transfer, up to 58 weeks

  18. Preterm Delivery Among Live Birth

    Delivery of a fetus at less than 37 and more than 28 weeks gestational age.

    Measured: 1 year after embryo transfer, up to 58 weeks

  19. Low Birth Weight Among Neonates

    Neonatal birth weight ≤ 2500 g.

    Measured: 1 year after embryo transfer, up to 58 weeks

  20. Congenital Anomalies Among Neonates

    Congenital anomalies are defined as structural or functional anomalies that occur during intrauterine life, including minor and major anomalies.

    Measured: 1 year after embryo transfer, up to 58 weeks

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Live Birth Rate (time frame: 1 year after embryo transfer day, up to a maximum duration of 58 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03703700, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
