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.

Detailed Description

This research is an experimental study with a randomized controlled clinical design involving two intervention groups: one receiving secretome injections and the other receiving intradermal platelet-rich plasma injections. Evaluations are conducted by measuring hair density and the terminal-to-vellus hair ratio before and after treatment using trichoscopy/dermoscopy.

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

  • Adult

Accepts Healthy Volunteers

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.

Experimental: UC-MSC Secretome
Umbilical Cord Mesenchymal Stem Cell-derived Secretome

Biological: Platelet-Rich Plasma (PRP) Injections
The centrifuged plasma solution was injected intradermally into the scalp at the alopecia site, with 0.1 ml per injection point spaced 1 cm apart, administered every 2 weeks for 8 weeks

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
Terminal-to-Vellus Hair Ratio
Time Frame: Baseline (before treatment), post-intervention (at 8 weeks), and during follow-up visits (months 3, 6, and 9)
The ratio of terminal hair (thick, pigmented hair, diameter >40 micrometer) to vellus hair (fine hair, diameter <30 micrometer) in areas of androgenetic alopecia
Baseline (before treatment), post-intervention (at 8 weeks), and during follow-up visits (months 3, 6, and 9)
Hair density
Time Frame: Baseline (before treatment), post-intervention (at 8 weeks), and during follow-up visits (months 3, 6, and 9)
The number of hairs per specific scalp area was measured in hairs/cm²
Baseline (before treatment), post-intervention (at 8 weeks), and during follow-up visits (months 3, 6, and 9)
