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

Topical minoxidil is the only US FDA approved drug used for the treatment of AGA in females. While topical minoxidil exhibits a good safety profile, the efficacy in the overall population remains relatively low i.e., 30-40% re-grow hair. To observe significant improvement in hair growth, minoxidil is typically used once daily for a period of at least 24 weeks. Due to the significant time commitment and low response rate, a diagnostic test to identify non-responders prior to initiating therapy would be advantageous.

Minoxidil is converted in the scalp to its active form, minoxidil sulfate, by the sulfotransferase enzyme SULT1A1. The enzyme expression is variable among individuals. We have demonstrated in two prior feasibility studies that the SULT1A1 enzyme activity in plucked hair follicles correlates with minoxidil response in the treatment of AGA and thus can server as a predictive biomarker.

Consequently, we developed a minoxidil response in-vitro diagnostic kit intended to identify non-responders prior to initiating therapy with 5% topical minoxidil foam.

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 and older (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.

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.
