About this study
Official title: The Efficacy of the Use of Cellular Matrix / A-CP-HA Kit (Combination of Autologous Platelet-rich Plasma and Non-cross-linked Hyaluronic Acid) Compared to Local Estrogen Therapy (Blissel, Estriol 50 Micrograms/g Vaginal Gel) in Women With Genitourinary Syndrome of Menopause. A Randomized Controlled Trial, With a Second Blind Observer.
This study is a randomized, controlled, non-inferiority trial, that will be performed on 192 women on Menopause (absence of menstruation for at least 12 months), with diagnostic of genitourinary syndrome of menopause (SGM) and a vaginal health index <15 points, that are sexually active.
Patients will be randomized 1:1, equal number assigned to each of the two treatment groups, to receive treatment with two dose of Cellular Matrix / A-CP-HA Kit (a combination of autologous platelet-rich plasma and non-cross-linked hyaluronic acid) separated for a month, and control group that will receive the standard treatment for SGM, local estrogen therapy (Blissel, estriol 50 micrograms/g vaginal gel).
Both groups will be follow-up for 3 and 6 month afther treatment, a blind observer will assess the application of the validated scale (VHIS, VHI), and the investigators will do the FSD, symptom record, maturation index, follow-up photography and evaluation of adverse events and treatment compliance and adherence.
Read the detailed description
This study is a randomized, controlled, non-inferiority trial, with a second blind observer, comparing effectiveness of the use of Cellular Matrix / A-CP-HA Kit (a combination of autologous platelet-rich plasma and non-cross-linked hyaluronic acid) to the standard line of treatment, local estrogen therapy (Blissel, estriol 50 micrograms/g vaginal gel) in women with genitourinary syndrome of menopause (SGM). Duration of the study estimated is 24 months.
A total of 192 menopausal women, with absence of menstruation for at least 12 months, ≤70 years old, that are sexually active and who report symptoms and signs of SGM, with a vaginal health index <15 points. Patients will be excluded if are in treatment with systemic or local hormonal treatment in the last 3 months, Tamoxifen or Aromatase inhibitor treatments. Vulvovaginal pathologies (condyloma, vaginal intraepithelial neoplasia, vaginal carcinoma, lichen sclerosus, lichen planus, history of radiation, history of cervical cancer, other gynecologic cancer, or pelvic radiation, or active genital infection (eg. g., bacterial vaginosis, genital herpes, candida). Contraindication for vaginal estrogen therapy. Women with thrombocytopenia or coagulation disorders, systemic infections, STDs, cancer of any type in recent treatment, connective tissue diseases. Women who have had pelvic surgery within 6 months.
Patients will be randomized 1:1, equal number assigned to each of the two treatment groups, to receive treatment with two dose of Cellular Matrix / A-CP-HA Kit (a combination of autologous platelet-rich plasma and non-cross-linked hyaluronic acid), separated for a month, and control group that will receive the standard treatment for SGM, local estrogen therapy (Blissel, estriol 50 micrograms/g vaginal gel).
Patients will interviewed about their medical history, age of menopause, symptoms related and history of treatments. Evaluation of the Vaginal Health Index (VHIS), Vulvar Health Index (VHI), vaginal pH, and vaginal maturation index (vaginal cytology). The intensity of VVA symptoms (vaginal burning, vaginal itching, vaginal dryness, dyspareunia and dysuria) will be measured using a 5-cm visual analog scale (VAS), and a valuation of Female Sexual Distress (FSD) score. Photographic monitoring during all phases of the procedure. Routine laboratory test serology will requested for both groups (valid up to 3 months).
Both groups will be follow-up for 3 and 6 month afther treatment, a blind observer will assess the application of the validated scale (VHIS, VHI), and the investigators will do the FSD, symptom record, maturation index, follow-up photography and evaluation of adverse events and treatment compliance and adherence.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Cellular Matrix / A-CP-HA KitDrug
For infiltration, a prior preparation of the region with anesthetic cream is performed, procaine 25 mg/g + lidocaine 25 mg/g (Emla 5% cream) in the vulvar area and vaginal introitus. Occlusion of the area with plastic film is performed for 20 minutes. After asepsis and antisepsis, infiltration is performed with mesotherapy needles 31G 4mm, using the technique of superficial "point-to-point" mesotherapy microinjections, in the vestibule and the first 3 cm of the posterior wall of the vagina.
Local estrogen therapy (Blissel, estriol 50 micrograms/g vaginal gel)Drug
Blissel®, Estriol vaginal gel 50 micrograms/g, daily application for 15-21 days in a row, then two times a week for 24 weeks (6 months). Application instructions will be explained to the patients. The gel should be applied in the vagina using an applicator with the marked dose, the full applicator should be inserted into the vagina and emptied, preferably at night.
| Study group | Role | What they receive |
|---|---|---|
| Cellular Matrix / A-CP-HA Kit | Experimental | (a combination of autologous platelet-rich plasma and non-cross-linked hyaluronic acid) is a sterile tube designed for use in the preparation of a mixture of PRP and hyaluronic acid, tube is under vacuum allowing the withdrawal of 6 ml of blood and contains: 2 ml of hyaluronic acid gel (20mg/ml, 40 mg per tube) in phosphate buffer. Not crosslinked, hyaluronic acid is obtained from bacterial fermentation, 3 g of inert cell-selector gel, and 0.6 ml of anticoagulant (sodium citrate 4%). Centrifuged at 1,500 g, 3,000 rpm for 5 min. Platelet recovery of more than 70%, granulocyte depletion of 94.3% and red blood cells of 99.5% are achieved. Receives: Drug: Cellular Matrix / A-CP-HA Kit |

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Cellular Matrix / A-CP-HA Kit and Local estrogen therapy (Blissel, estriol 50 micrograms/g vaginal gel) in people with Genitourinary Syndrome of Menopause, run by Fundación Santiago Dexeus Font at 1 site in Spain.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 21 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Percentage of patients with improved symptomatology. (time frame: at 6 months after treatment). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Sep 2026.
