NCT04586686

Brief Summary

This clinical prospective randomised controlled trial will evaluate the impact of an ovarian biopsy on the oocyte yield after controlled ovarian stimulation before chemotherapy in view of breast cancer. The purpose of this trial is to learn about the possibility to combine these two fertility preservation procedures without decreasing the number of oocytes collected after an ovarian stimulation.

Study Arms (2)

Group 1: right ovarian biopsy

OTHER

Patients in group 1 will undergo a laparoscopy for an ovarian biopsy from the right ovary. They will then continue with a controlled ovarian stimulation, using a GnRH antagonist protocol. This will be started with Corifollitropin alfa 0.15 mg in the evening. On day six the antagonist, Ganirelix, will be added in the morning. If needed stimulation can be continued after seven days using follitropin beta daily in the evening (dosage ranging from 200-300 IE depending on AMH levels). Agonist trigger Triptorelin 0.2 mg will be administered for ovulation induction. In case of LH levels \<2 IU/L at the start of ovarian stimulation, a dual ovulation strategy will be adapted: Triptorelin 0.2mg and choriongonadotropin 2500 IU (or choriongonadotropin alfa 250 µg) will be given. A transvaginal oocyte retrieval will be planned 36 hours after triggering.

Procedure: Ovarian biopsy via laparoscopyProcedure: Transvaginal oocyte retrieval

Group 2: left ovarian biopsy

OTHER

Patients in group 2 will undergo a laparoscopy for an ovarian biopsy from the left ovary. They will then continue with a controlled ovarian stimulation, using a GnRH antagonist protocol. This will be started with Corifollitropin alfa 0.15 mg in the evening. On day six the antagonist, Ganirelix, will be added in the morning. If needed stimulation can be continued after seven days using follitropin beta daily in the evening (dosage ranging from 200-300 IE depending on AMH levels). Agonist trigger Triptorelin 0.2 mg will be administered for ovulation induction. In case of LH levels \<2 IU/L at the start of ovarian stimulation, a dual ovulation strategy will be adapted: Triptorelin 0.2mg and choriongonadotropin 2500 IU (or choriongonadotropin alfa 250 µg) will be given. A transvaginal oocyte retrieval will be planned 36 hours after triggering.

Procedure: Ovarian biopsy via laparoscopyProcedure: Transvaginal oocyte retrieval

Interventions

A laparoscopy will be performed to achieve an ovarian cortical biopsy of one of both ovaries. Approximately twenty % of the ovarian volume as initially measured on the baseline ultrasound at the first visit will be removed to be processed in the lab for cortex freezing. The laparoscopic procedure in order to take the ovarian cortex biopsy will be standardised as much as possible. The technique developed by ProFam will be followed and adapted if needed by the surgeon's discretion. A three to four port laparoscopy will be used. The ovarian cortex biopsy will be taken using a curved scissor. Bipolar or unipolar cauterisation will be avoided as much as possible. If necessary for approximation or for hemostatic reasons, the ovarian edges can be stitched or Surgicel ® Absorbable Hemostat can be used.

Group 1: right ovarian biopsyGroup 2: left ovarian biopsy

After ovarian stimulation, a transvaginal oocyte retrieval will be performed either under local or general anaesthetics (patient's choice). The oocyte yield between the biopsied and non-biopsied ovary will be evaluated.

Intervention Model
PARALLEL
Model Details: All patients will undergo a laparoscopy for an ovarian biopsy (about 20% of the ovarian volume). The side of the ovarian biopsy will be randomized on the day of the laparoscopy either from the right side (group 1) or from the left side (group 2). All patients will then continue with a controlled ovarian stimulation, using corifollitropin alpha and follitropin beta in a GnRH antagonist protocol using ganirelix. The metaphase II oocyte yield will be evaluated between the biopsied versus non-biopsied ovary to proof a non-inferiority (assuming that a difference of 1 metaphase II oocyte yielded from the biopsied ovary compared to the non-biopsied ovary is not clinically relevant).
