Eligibility
Key inclusion criteria
1. Confirmation of onychomycosis by mycological staining and/or culture from affected
great toenail(s).

2. Appearance of onychomycosis involving 20% to 70% of 1 (or both) affected great
toenail(s) as determined by visual inspection after the nail has been trimmed. If the
percentage of infection is outside this range but is still considered appropriate for
this study, based on the overall impression of the Investigator, participation can be
considered in consultation with the Medical Monitor.

3. The combined thickness of the distal nail plate at the associated hyperkeratotic nail
bed is less than 3 mm.

4. Medically healthy with clinically insignificant Screening results (eg, laboratory
profiles, medical history, ECGs, physical exam), as judged by the PI.

5. Negative urine drug screen and alcohol breath test at Screening and Day 1.

6. Body Mass Index (BMI) between 17.5 and 35.0, inclusive.

7. Agree to adhere to the current state and national advice regarding minimizing exposure
to coronavirus disease of 2019 (COVID-19) from the Screening visit until the EOS
visit.
Minimum age
18 Years
Maximum age
65 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
1. History of allergy to any of the excipients in ATB1651.

2. Positive COVID-19 test at Screening or any symptoms consistent with COVID-19 prior to
initial dosing.

3. Positive test for hepatitis C antibody (HCV), hepatitis B surface antigen (HBsAg), or
human immunodeficiency virus (HIV) antibody at Screening.

4. Have any underlying physical or psychological medical conditions that, in the opinion
of the Investigator, would make it unlikely that the participant will comply with the
study.

5. Pregnant or lactating at Screening or planning to become pregnant (self or partner) at
any time during the study, including the follow-up period.

6. Unwilling to refrain from the use of nail cosmetics such as clear and/ or colored nail
lacquers from the Screening visit until the end of the study.

7. Use of any IP or investigational medical device within 30 days prior to Screening, or
5 half-lives of the product (whichever is the longest) or participation in more than 4
investigational drug studies within 1 year prior to Screening.
