Study Details

Study Description

Brief Summary

The purpose of this study is to evaluate the effect of using a purified botulinum toxin (Xeomin®, Merz, USA), the same injectable used to improve face wrinkles, to treat a specific type of hair loss seen in men and women not associated with scarring or other internal disease called 'pattern hair loss'. This type of hair loss is medically called 'androgenic or androgenetic alopecia'. In men it is typically called 'male pattern baldness' whereas in women it is called 'female pattern baldness' and in both cases is hereditary meaning there will be a history of relatives that describe having the same condition.

Condition or Disease Intervention/Treatment Phase
  • Drug: incobotulinumtoxin A
 Phase 2

Detailed Description

Adult volunteers aged 22-45 years presenting with mild to moderate patterned hair loss will be screened for participation. Twenty subjects (10 males and 10 females) meeting the inclusion/exclusion criteria will be recruited to participate. Prior to any injections a global photograph documenting the patterned hair loss will be acquired for each individual utilizing the Canfield global camera system. Each subject will then undergo trichoscopy imaging within the defined treatment area using the Canfield HairMetrix® system. The imaged area is at a higher magnification capable of reliable measurements for hair density (count/cm2), hair shaft diameter, follicular units, among other measurements captured by the software. Individual balding scalps will be outlined and mapped to include up to 30 injection sites evenly distributed within the hair loss area.

At each site, 5 Units of Xeomin® will be injected with a maximum of 150 Units total per subject. This will be a single, one-time treatment session. Consequently, subjects will be contacted by phone or will be asked to come into the clinic for follow up according to a set schedule.

At each follow up visit (monthly) subjects will be asked to report any adverse events. Follow up visits at the clinic will also include photographic documentation, trichoscopy, and investigator and subject subjective reporting of treatment progress.

There will be a total of up to 3 injectors, 1 person taking photographs (including trichoscopy), and 1 investigator assessing treatment outcome.

During this 9 month-long study, subjects cannot utilize other hair loss treatments and must maintain their grooming routine which includes maintaining their hair style.

      Trichoscopy equipped with Canfield HairMetrix® software system will be performed on the scalp of study participants. The baseline Terminal:Vellus ratio will be compared to day 30, day 90, day 180 and day 270.

    4. Changes from baseline in Average hairs per follicular unit (average number of hairs within a hair follicle). [Day 30, Day 90, Day 180, and Day 270]

      Trichoscopy equipped with Canfield HairMetrix® software system will be performed on the scalp of study participants. The baseline average hairs per follicular unit will be compared to day 30, day 90, day 180 and day 270.

    5. Changes from baseline in Average hair width (microns) (average thickness of hair in microns). [Day 30, Day 90, Day 180, and Day 270]

      Trichoscopy equipped with Canfield HairMetrix® software system will be performed on the scalp of study participants. The baseline average hair width (microns) will be compared to day 30, day 90, day 180 and day 270.

    6. Changes from baseline in Follicle count per cm2 (number of follicles per square centimeter). [Day 30, Day 90, Day 180, and Day 270]

      Trichoscopy equipped with Canfield HairMetrix® software system will be performed on the scalp of study participants. The baseline follicle count per cm2 will be compared to day 30, day 90, day 180 and day 270.

    7. Mean Inter-follicular distance (mm) (mean distance between follicular units). [Day 30, Day 90, Day 180, and Day 270]
