Arm Intervention/treatment
Experimental: ATI-50002 Topical Solution

This is an open-label phase 2 study designed to evaluate the safety and efficacy of ATI- 50002 Topical Solution, 0.46% in male and female subjects with androgenetic alopecia.

Subjects will be required to apply ATI-50002 study medication to their scalp twice a day for a total of 26 weeks.

Drug: ATI-50002
ATI-50002 Topical Solution




Primary Outcome Measures :
  1. Mean Change From Baseline in Target Area Hair Count (TAHC) [ Time Frame: Baseline to 26 Weeks ]
    Target Area Hair Count will measure the hairs/cm2 on a subject's head. Higher values represent better outcomes.


Secondary Outcome Measures :
  1. Mean Change From Baseline in Target Area Hair Count (TAHC) [ Time Frame: Baseline to 52 Weeks ]
    Target Area Hair Count will measure the hairs/cm2 on a subject's head. Higher values represent better outcomes.

  2. Mean Change From Baseline in Cumulative Target Area Hair Width (TAHW) [ Time Frame: Baseline to 26 Weeks ]
    Target Area Hair Width (TAHW) will measure the cumulative width of hair in the subject's target area. Higher values represent better outcomes.

  3. Mean Change From Baseline in Cumulative Target Area Hair Width (TAHW) [ Time Frame: Baseline to 52 Weeks ]
    Target Area Hair Width (TAHW) will measure the cumulative width of hair in the subject's target area. Higher values represent better outcomes.

  4. Investigator Global Assessment: Total Subjects With Slightly Increased Hair Growth or Better Using a Seven-point Rating Scale [ Time Frame: Baseline to 26 Weeks ]
    Investigators will use a 7 point rating scale to assess hair growth following treatment with study medication. A score of +3 corresponds to significant hair growth and a score of -3 corresponds to lack of hair growth. Subjects with a score of +1 to +3 were considered to have slightly increased hair growth or better.

  5. Investigator Global Assessment: Total Subjects With Slightly Increased Hair Growth or Better Using a Seven-point Rating Scale [ Time Frame: Baseline to 52 Weeks ]
    Investigators will use a 7 point rating scale to assess hair growth following treatment with study medication. A score of +3 corresponds to significant hair growth and a score of -3 corresponds to lack of hair growth. Subjects with a score of +1 to +3 were considered to have slightly increased hair growth or better.

  6. Subject Self-Assessment: Total Subjects With Slightly Increased Hair Growth or Better Using a Seven-point Rating Scale [ Time Frame: Baseline to 26 Weeks ]
    Subjects will use a 7 point rating scale to assess hair growth following treatment with study medication. A score of +3 corresponds to significant hair growth and a score of -3 corresponds to lack of hair growth. Subjects with a score of +1 to +3 were considered to have slightly increased hair growth or better.

  7. Subject Self-Assessment: Total Subjects With Slightly Increased Hair Growth or Better Using a Seven-point Rating Scale [ Time Frame: Baseline to 52 Weeks ]
    Subjects will use a 7 point rating scale to assess hair growth following treatment with study medication. A score of +3 corresponds to significant hair growth and a score of -3 corresponds to lack of hair growth. Subjects with a score of +1 to +3 were considered to have slightly increased hair growth or better.

  8. Change From Baseline in Androgenetic Alopecia (AGA) Using the Norwood-Hamilton Scale [ Time Frame: Baseline to 26 Weeks ]

    Measure Description: Subject's level of hair loss at baseline based on the Norwood Hamilton Scale for male subjects.

    Type I: Minimal or no recession of the hairline Type II: Triangular areas of recession at the frontotemporal hairline Type III: Deep symmetrical recession at the temples are bare or only sparsely covered by hair Type IV: Frontotemporal recession is more severe than in Type III with sparse or no hair on the vertex Type V: The vertex hair loss region is separated from the frontotemporal region but is less distinct Type VI: Sparse hair remaining Type VII: The most severe form of hair loss. Lower scores represent better outcomes.


  9. Change From Baseline in Androgenetic Alopecia (AGA) Using the Norwood-Hamilton Scale [ Time Frame: Baseline to 52 Weeks ]

    Measure Description: Subject's level of hair loss at baseline based on the Norwood Hamilton Scale for male subjects.

    Type I: Minimal or no recession of the hairline Type II: Triangular areas of recession at the frontotemporal hairline Type III: Deep symmetrical recession at the temples are bare or only sparsely covered by hair Type IV: Frontotemporal recession is more severe than in Type III with sparse or no hair on the vertex Type V: The vertex hair loss region is separated from the frontotemporal region but is less distinct Type VI: Sparse hair remaining Type VII: The most severe form of hair loss. Lower scores represent better outcomes.


  10. Change From Baseline in Androgenetic Alopecia (AGA) Using the Sinclair Scale [ Time Frame: Baseline to 26 Weeks ]

    Treating investigators will be required to rate the subject's level of hair loss at baseline based on the Sinclair scale for women.

    Grade 1: is normal. This pattern is found in all girls prior to puberty but in only forty-five percent of women aged eighty or over.

    Grade 2: shows a widening of the central part. Grade 3: shows a widening of the central part and thinning of the hair on either side of the central part.

    Grade 4: reveals the emergence of a diffuse hair loss over the top of the scalp.

    Grade 5: indicates advanced hair loss. Lower grades represent better outcomes.


  11. Change From Baseline in Androgenetic Alopecia (AGA) Using the Sinclair Scale [ Time Frame: Baseline to 52 Weeks ]

    Treating investigators will be required to rate the subject's level of hair loss at baseline based on the Sinclair scale for women.

    Grade 1: is normal. This pattern is found in all girls prior to puberty but in only forty-five percent of women aged eighty or over.

    Grade 2: shows a widening of the central part. Grade 3: shows a widening of the central part and thinning of the hair on either side of the central part.

    Grade 4: reveals the emergence of a diffuse hair loss over the top of the scalp.

    Grade 5: indicates advanced hair loss. Lower grades represent better outcomes.
