Beschrijving

Inclusion Criteria:

  • Clinical diagnosis of AGA

  • Males who are sexually active and have a partner who is capable of becoming pregnant, neither of whom have had surgery to become sterilized, that are not using an effective method of birth control and are not willing to use an effective method of birth control during the study treatment period until 90 days post last dose of study medication
  • Current skin disease (e.g., psoriasis, atopic dermatitis, skin cancer, eczema, sun damage, seborrheic dermatitis), cuts and/or abrasions on the scalp or condition (e.g., sunburn, tattoos) on the treatment area that, in the opinion of the Investigator, might put the subject at risk or interfere with the study conduct or evaluations
  • History of surgical correction of hair loss on the scalp
  • Previous exposure to SM04554
  • Use of any products or devices purported to promote scalp hair growth (e.g., finasteride or minoxidil) within the 24 weeks prior to study start
  • Use of anti-androgenic therapies (e.g., spironolactone, flutamide, cyproterone acetate, cimetidine) within 12 weeks prior to study start
  • History of hair transplants
  • Current use of an occlusive wig, hair extensions, or hair weaves
  • Participation in any other investigational drug or medical device trial, which included administration of an investigational study medication or medical device, within 30 days or 5 half-lives of the investigational agent, whichever is longer, prior to study start
  • Subjects with a history of clinically significant cardiac arrhythmia as determined by the Investigator
  • Subjects with clinically significant findings from medical history, clinical laboratory tests, electrocardiogram (ECG), or vital signs that, in the opinion of the Investigator, could interfere with the objectives of the study or put the subject at risk
  • Subjects unwilling to refrain from sperm donation during the study treatment period until 90 days post last dose of study medication
  • Subjects with pregnant partners at study start
  • Use of semi-permanent hair products (e.g., color, texturizers, relaxers) within 30 days prior to study start

Tijdsspanne
Change From Baseline in Non-vellus Hair Count
Tijdsspanne: Day 45, Day 90, and Day 135

Change from baseline in non-vellus hair count over time.

Non-vellus hair count was determined by macrophotography. Standardized macrophotography color photographs of the treatment area were taken on Visit Day 0 (pre-treatment), as well as on Visit Days 45 and 90, and 135. A circular area of the subject's hair 1.9 cm in diameter was clipped to approximately 1 mm in length prior to performing the macrophotography. On Visit Day 0, a scalp tattoo approximately 1 mm in size and located in the center of the target area of hair was applied to anchor the macrophotography. Photos were uploaded from sites to the vendor where blinded assessment of the macrophotography took place.

Day 45, Day 90, and Day 135
Change in Subject Assessment of Hair Growth and Quality
Tijdsspanne: Day 45, Day 90, and Day 135

Change in Men's Hair Growth Questionnaire (MHGQ) over time as compared to Baseline. The MHGQ is a subject-completed assessment that asks the subject to evaluate his hair growth and quality since the start of the study.

Day 45, Day 90, and Day 135

Tijdsspanne
Change in Hair Growth as Assessed by the Investigator
Tijdsspanne: Day 45, Day 90, and Day 135

Change in hair growth over time as compared to Baseline, as assessed by the investigator, using a 7-point scale from -3 (greatly decreased) to +3 (greatly increased). Responses were analyzed using logistic regression modeling improvement vs no change/worsening of hair status at each visit.

Day 45, Day 90, and Day 135
Impact of AGA on Quality of Life
Tijdsspanne: Day 45, Day 90, and Day 135

Change from baseline in subject responses to the Kingsley Alopecia Profile (KAP) questionnaire over time.

The KAP is a validated, patient-reported outcome that quantitatively measure the impact androgenetic alopecia on the subject's quality of life. Each of the 38 KAP 5-category Likert-scaled questions was scored +2 'Strongly Agree' to -2 'Strongly Disagree.' The KAP score was summed across all 38 questions for a score ranging from +76 to -76, with higher scores indicating an increasing negative impact on quality of life. Change from baseline was calculated as visit - baseline such that negative values reflecting improving quality of life.

Day 45, Day 90, and Day 135
Change From Baseline in Total Sum of Hair Width
Tijdsspanne: Day 45, Day 90, and Day 135

Non-vellus hair width was determined by macrophotography. Standardized macrophotography color photographs of the treatment area were taken on Visit Day 0 (pre-treatment), as well as on Visit Days 45 and 90, and 135. A circular area of the subject's hair 1.9 cm in diameter was clipped to approximately 1 mm in length prior to performing the macrophotography. On Visit Day 0, a scalp tattoo approximately 1 mm in size and located in the center of the target area of hair was applied to anchor the macrophotography. Photos were uploaded from sites to the vendor where blinded assessment of the macrophotography took place.

While the protocol and SAP listed this outcome as hair density, the actual outcome analyzed was the total sum of non-vellus hair width in microns within the target area provided by macrophotography.
