Clinical Trial Summary

This is an open label study of ATI-502 Topical Solution for the treatment of AA, AU, and AT with the following goals:

• To assess the safety, tolerability, and efficacy of ATI-502 Topical Solution in subjects with AA, AU or AT following 24 weeks of treatment with ATI-501 Oral Suspension or Placebo Suspension.

• To assess the ability of ATI-502 Topical Solution to maintain or improve hair regrowth in subjects previously treated with ATI-501 Oral Suspension or Placebo Suspension.

Description:

This Phase 2, multicenter, open-label study will evaluate the safety, tolerability, efficacy, and durability of efficacy of ATI-502 Topical Solution, 0.46% for the treatment of alopecia areata (AA), alopecia universalis (AU) and alopecia totalis (AT) in adult subjects who completed 24 weeks of treatment with ATI-501 Oral Suspension or Placebo Suspension.

Subjects who complete 24 weeks of active treatment with ATI-501 Oral Suspension or Placebo Suspension in study ATI-501-AUAT-201 will be assessed for eligibility to enter the study. At Visit 9 in study ATI-501-AUAT-201, subjects who did not experience any adverse events (AEs), serious adverse events (SAEs), or tolerability issues that met study discontinuation criteria in study ATI-501-AUAT-201 and who in the opinion of the investigator are capable of re-growing or maintaining scalp hair and meet the entry criteria are eligible to enroll in this open-label study.

Enrolled subjects will apply ATI-502 Topical Solution, 0.46% BID to the entire scalp and if applicable, the eyebrow(s) and return for safety and efficacy assessments as detailed in the Schedule of Assessments (Table 3). Assessment of response to treatment will be performed at Week 4, Week 8, Week 16, Week 24, and post-treatment Week 28. Safety and tolerability will be evaluated at each study visit by assessment of adverse events, clinical laboratory tests, and vital signs, and at Week 24, and physical examination findings

8. Be willing to maintain the same general hair style throughout the study period. Subjects who shave their scalp must be willing to refrain from shaving their scalp for at least one week or longer prior to each study visit, as determined by the investigator based on visible scalp hair growth. Hair trimming outside the treatment areas to maintain the current hair style is permitted.

9. Be willing and able to follow all study instructions and to attend all study visits.

10. Sexually active male subjects must agree to use a barrier method of contraception from the first application of study medication to at least 30 days after the last application of study medication.

Exclusion Criteria:

• Subjects are excluded from this study if any 1 or more of the following criteria is met:

1. Any study medication discontinuation criteria are met during participation in study ATI-501-AUAT-201.

2. Females who are nursing, pregnant, or planning to become pregnant for the duration of the study and up to 30 days after the last application of study medication.

3. The presence of a permanent or difficult to remove hairpiece or wig that will, in the opinion of the investigator, interfere with study assessments if not removed at each visit.

4. Sensitivity to any of the ingredients in the study medications.

5. Unwillingness to refrain from weaves, hair extensions, or shaving of the scalp for at least one week or longer prior to each study visit, as determined by the investigator based on visible scalp hair growth the duration of the study.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in the Severity of Alopecia Tool (SALT) Score	The Severity of Alopecia Tool (SALT) score is a physician administered scale measuring the amount of scalp without any terminal hair assessed by the investigator. Possible scores range from 0 (no scalp hair loss) to 100 (complete scalp hair loss). A negative change in the SALT score over time represents hair regrowth by adding the percentage hair loss in the various areas (i.e. top, back, each side) of the scalp. For the primary endpoint, the primary efficacy variable was the mean relative percent change from the original baseline visit in study ATI-501-AUAT-201 and the SALT score at Week 24 on study ATI-502-AA-203. This represents the percentage of hair regrowth. It was calculated as the mean of the changes from baseline SALT score to the SALT score at Week 24, divided by baseline SALT score and expressed as a percentage.	Baseline to Week 24
Secondary	Mean Relative Percent Change From Baseline SALT Score	Mean Relative Percent Change from Baseline (from the current study ATI-502-AA-203) in Severity of Alopecia Tool (SALT). SALT score is on a percent scale where 0% is no hair loss and 100 % is total hair loss. A lower SALT score is a better outcome. A higher relative percent change is better.	Baseline to Week 24
Secondary	Proportion of Subjects Achieving a SALT50 (Defined as a = 50% Improvement From Baseline in SALT) by Visit	Proportion of subjects achieving a SALT 50 (defined as a = 50% improvement from baseline in SALT) by visit 6. SALT score is on a percent scale where 0% is no hair loss and 100 % is total hair loss.	Baseline to Week 24
Secondary	Proportion of Subjects Achieving a SALT 75 (Defined as a = 75% Improvement From Baseline in SALT) by Visit	Proportion of subjects achieving SALT 75 (defined as a = 75% improvement from baseline in SALT) by visit 6 SALT score is on a percent scale where 0% is no hair loss and 100 % is total hair loss. A bigger percent change is a more positive score.	Baseline to Week 24
Secondary	Durability of Response	Durability of response: Proportion of subjects achieving a SALT 50 or SALT 75 at Week 24 (in study ATI-501-AUAT-201) and maintaining that response at week 24 in ATI-502-AA-203 study.	Baseline to Week 24
Secondary	Change From Baseline in the Physician Global Impression of Severity (PhGIS)	Change from Baseline in the PhGIS by visit. The PhGIS is a 5 point scale from Mild to Extremely Severe. Mild is a better outcome.	Baseline to Week 24
