Trial summary

Topical minoxidil is the most common drug used for the treatment of AGA in men. While topical minoxidil exhibits a good safety profile, the efficacy in the overall population remains relatively low i.e., 30-40% re-grow hair. Read more about this study

About this study

Topical minoxidil is the most common drug used for the treatment of AGA in men. 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 twice daily for a period of at least 16 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.

The primary purpose of this study is to evaluate the clinical validity of the minoxidil response in-vitro diagnostic kit.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Sensitivity and specificity of the minoxidil response in-vitro diagnostic kit to predict at baseline the mean change in non-vellus hair count in the target region

    Measured: baseline to week 16

  2. Sensitivity and specificity of the minoxidil response in-vitro diagnostic kit to predict at baseline the subjects ratings

    Measured: baseline to week 16

Secondary outcomes (3)
  1. Sensitivity and specificity of the minoxidil response in-vitro diagnostic kit to predict at baseline the treatment efficacy evaluated by expert panel review of global photographs assessing hair regrowth

    Measured: baseline to week 16

  2. Sensitivity and specificity of the minoxidil response in-vitro diagnostic kit to predict at baseline the mean change in non-vellus hair diameter in the target region

    Measured: baseline to week 16

  3. Mean change in minoxidil sulfotransferase activity in plucked hairs as measured by the minoxidil response in-vitro diagnostic kit

    Measured: baseline to week 16

Questions about this trial

What is this clinical trial studying?

An observational study of Androgenetic Alopecia, run by Applied Biology, Inc. at 5 sites in 4 countries.

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 7 inclusion and 8 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 5 Oct 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in United States, Australia, India, Italy. 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.

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?

Sensitivity and specificity of the minoxidil response in-vitro diagnostic kit to predict at baseline the mean change in non-vellus hair count in the target region (time frame: baseline to week 16). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02198261, which also lists 4 linked publications.

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 5 Oct 2018.
