Plasma Rich in Growth Factors (PRGF-Endoret)in the Treatment of Androgenetic Alopecia

February 4, 2025 updated by: Biotechnology Institute IMASD

A Pilot Randomized, Double-blind, Placebo-controlled Clinical Trial to Obtain Preliminary Data on Efficacy and Safety in the Application of PRGF-Endoret by Mesotherapy, in the Treatment of Male and Female Androgenetic Alopecia of Over 6 Months Duration.

  • Androgenetic alopecia (AGA) or common baldness is the most common cause of hair loss in both men and women and is caused by the action of androgens in genetically predisposed individuals.
  • This clinical trial was designed to evaluate the efficacy and safety of using a preparation of autologous plasma rich in growth factors (PRGF-Endoret) in the treatment of androgenetic alopecia.

Study Overview

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change from baseline in Hair density at three months (number of hairs per cm2)
Time Frame: 3 months post-treatment
Hair density (number of hairs per cm2) will be measured for each treatment group
3 months post-treatment

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Hair Width (micrometers)
Time Frame: Basal, 1, 2, and 3 months post-treatment
Hair width will be measured for each treatment group
Basal, 1, 2, and 3 months post-treatment
Anagen/telogen ratio
Time Frame: Basal, 1, 2, and 3 months post-treatment
Hair cycle has different phases. Two of the most important are anagen (active growth phase of hair follicles) and telogen (resting phase of the hair follicle). This secondary outcome measure allows to measure the efficacy of the PRGF-Endoret treatment.
Basal, 1, 2, and 3 months post-treatment
Terminal Hair Density
Time Frame: Before each one of the treatments and 1, 2 and 3 months post-treatment.
Terminal hair density will be established for each one of the treatments
Before each one of the treatments and 1, 2 and 3 months post-treatment.
Vellous hair density
Time Frame: Basal,1, 2 and 3 months post-treatment
Vellous hair will be measured for each treatment group
Basal,1, 2 and 3 months post-treatment

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
September 1, 2015

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
