4-step ASCOT in POI Women to Promote Follicular Rescue

Phase 3

Completed

• Conditions: Premature Ovarian Insufficiency
• Interventions: Drug: G-CSF treatment for Bone marrow derived stem cell Mobilization; Procedure: Platelet Rich Plasma ovarian injection

• Registration Number: NCT04475744
• Lead Sponsor: Fundación IVI

Brief Summary

To promote follicular development in POI women, G-CSF mobilized activated platelet rich plasma will be directly injected into the ovarian medulla.

This is a prospective, observational, multicentric, open, pilot-controlled randomized trial which seeks to evaluate the impact of the 4-step ASCOT technique on the ovarian reserve and reproductive outcomes of POI patients. The study will be developed in two phases.

In a first step, POI women will randomized to control or undergo the 4-step ASCOT technique based on the direct ovarian injection of G-CSF mobilized and activated PRP. Follow up (AFC, AMH, FSH and E2 determinations) will be developed for 3 month in the controls and for 6 months in the treated and COS initiated if growing antral follicles detected. In the second phase, POI women allocated to control group after completed the follow up period will undergo the 4-step ASCOT technique, as described in the previous phase but only one ovary will be injected, then they will undergo a 6-month follow up period as described above.

Arm && Interventions

Group	Intervention	Description
4-step ASCOT arm	G-CSF treatment for Bone marrow derived stem cell Mobilization	POI women randomized to the 4-step ASCOT technique will receive a direct ovarian injection of G-CSF mobilized and activated PRP. For each patient, both ovaries will be directly injected with the G-CFS activated PRP (4-step ASCOT). Follow up (AFC, AMH, FSH and E2 determinations) will be developed for 6 months and COS initiated if growing antral follicles detected.

Primary Outcome Measures

Name	Time	Method
AFC	6-month	Follicular development assessed by antral follicular count between controls and treated patients after the 4-step ASCOT technique during the follow up period.

Secondary Outcome Measures

Name	Time	Method
Ovarian function (YES/NO)	6-12 months	Antral follicles detected by untrasound, menses recover and decrease in FSH levels will be considered as positive ovarian function
FSH, AMH and E2 levels	6-month	hormone levels in plasma
Number of COS and IVF cycle parameters for each patient, initiated before and after treatment.	6-month	COS and IVF cycle variables will be recorded if COS initiated
Menses recovery (YES/NO)	6-12 months	If menses recovery is noted by patients should be informed and recorded
