Clinical Trial Summary

In the last years, platelet-rich plasma (PRP) has emerged as a promising alternative to treat endometrial pathologies affecting the endometrial lining. Different studies have tried this therapeutic approach in human patient, but results are not conclusive at all. Also, in the last years, different studies have suggested the umbilical cord blood has a stronger reservoir of growth factors and other pro-regenerative molecules than the adult peripheral blood. That is the reason why the present study aims to evaluate if using platelet-rich plasma obtained from umbilical cord blood is able to increase endometrial thickness and prepare the endometrium for an embryo transference. However, due to the novelty of this approach, the investigators have considered to include a 'proof of concept' group (women with premature ovarian insufficiency) to obtain a deeper understanding of the clinical value of this blood derivative.


Description:

Phase II clinical trial, designed as a pilot study, single-center and open-label, which aims to study the efficacy of platelet-rich plasma from umbilical cord after injection into a pathological endometrium (thin endometrium, Asherman's Syndrome, endometrial atrophy). This treatment will be applied to patients with the aforementioned endometrial pathologies (group B), as well as to patients with premature ovarian failure (group A), which will serve to study its clinical value in greater detail. Plasma samples as well as endometrial biopsies will be analyzed to try to understand what molecular events are triggered in the endometrial tissue after the application of the treatment under study.

Intervention

Procedure:
Injection of hUC-PRP by hysteroscopy
PRP previously frozen at -80ºC (6±2 mL) will be defrozen after checking donor-receptor compatibility and viral safety study. PRP (4±2 mL) will be activated with 5% CaCl2 and immediately injected (4±2 mL) in the sub-endometrial wall via hysteroscopy.
Drug:
Oestraclin
Patients will receive estrogenic therapy, based on estradiol, for 10±2 days (oestraclin, topical cream, 5µg daily for 10±2 days).
Procedure:
Umbilical cord blood collection
The SCU will be collected using a blood collection bag containing anticoagulant. This step will be performed by the medical and nursing staff of the obstetrics service of the HUP La Fe. The blood collection bags will be the following, or similar: Cord Blood Collection Bags from MACOPHARMA; CPD Umbilical Cord Bag from GRIFOLS.
Endometrial biopsy
Biopsies will be taken by specialized medical personnel by aspiration with an intrauterine cannula (pipelle or cornier). Samples will be collected in 15 mL tubes (or in a larger capacity container if needed) containing PBS or RNA later until frozen at -80ºC, at the IVI Foundation facilities. Prior to freezing (in a 1.8-2 mL cryotube) the PBS will be removed and the sample cleaned in a Petri dish if needed.

Outcome

Type Measure Description Time frame Safety issue
Primary Study of endometrial regeneration and/or improvement in patients with endometrial pathologies (thin endometrium/Asherman's syndrome/endometrial atrophy) treated with platelet-rich plasma from the umbilical cord by endometrial thickeness. Improvement will be studied in form of tissue thickening (mm), comparing endometrial thickness before and after PRP injection An average of 3 months
Secondary Proof-of-concept in POI patients by improvement endometrial thickeness. Improvement will be studied in form of tissue thickening (mm), comparing endometrial thickness before and after PRP injection. An average of 3 months
Secondary Study of implantation, pregnancy, miscarriage and live newborn rates after injection of the investigational drug (platelet-rich plasma from umbilical cord) by questionnaire at different visits. If the thickness is good enough, patients will undergo embryo transfer and implantation, pregnancy, miscarriage or live newborn rates will be asked in subsequent visits. Through study completion, an average of 1 year
Secondary Gene and protein level evaluation of the endometrial biopsies collected. Different molecular and histological assays will be performed with the biopsies from all the groups. An average of 3 years
Secondary Study of the molecular composition of the different plasma fractions obtained from collected umbilical cord samples. Different molecular assays will be performed with the blood samples obtained. An average of 3 years
