Study 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.

Read the detailed 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.

Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

Interventions

  • ProcedureInjection 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.

  • DrugOestraclin

    Patients will receive estrogenic therapy, based on estradiol, for 10±2 days (oestraclin, topical cream, 5µg daily for 10±2 days).

  • ProcedureUmbilical 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.

  • ProcedureEndometrial 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.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 24, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
