  3. Subject has 3 eligible Seborrheic Keratoses; 2 target SKs must be on the face, and the additional 1 target SK must be on the neck or decolletage.
  4. Subjects must have had cryosurgery for SK removal within the last 6 months and prior to first treatment with A-101 Topical Solution.
  5. Target and non-target SKs must not have been previously treated.
  6. Subject is in good general health and free of any known disease state or physical condition which, in the investigator's opinion, might impair the evaluation of any target or non-target SK or which exposes the subject to an unacceptable risk by study participation

Exclusion criteria

Exclusion Criteria:

  1. Subject has clinically atypical and /or rapidly growing Seborrheic Keratoses.
  2. Subject has current systemic .
  3. Subject would require the use of any topical treatment (e.g., moisturizers, sunscreens) to any of the target or non-target SKs 12 hours prior to any study visit.
  4. Subject has any current skin disease (e.g., psoriasis, atopic dermatitis, eczema, sun damage), or condition (e.g., sunburn, excessive hair, open wounds) that, in the opinion of the investigator, might put the subject at undue risk by study participation or interfere with the study conduct or evaluations
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

What researchers measure

Primary outcomes

  1. Subject Satisfaction

    Subject Satisfaction Questionnaire after treatment with A-101 Topical Solution

    Time frame: Day 113

Secondary outcomes

  1. Effectiveness of Treatment

    Effectiveness of treatment as measured by the Physician Lesion Assessment scale. The Physician Lesion Assessment Scale (PLA) is a 4 point scale used by the investigator to assess each subjects SK lesion. PLA=0 (Clear);PLA=1 (Near Clear; not elevated); PLA=2 (Thin;thickness \</= 1 mm); PLA=3 (Thick; thickness \> 1 mm).

    Time frame: Day 113

  2. Comparison of Physician Lesion Assessment Score (PLA) to Subject Satisfaction

    Effectiveness of treatment assessed by PLA (4-point scale) compared to subject reported satisfaction with treatment. The PLA scale is a 4 point scale used by the investigator to assess each subject's SK lesion.

Adverse events

Collected over 17 weeks; The reporting period for SAEs began when the subject signed the informed consent form. Non serious clinical AEs were collected following the application of the study drug at Visit 2 and continued through Visit 11. All safety reporting (AEs and SAEs) was concluded at Visit 11 (Day 113).. Non-serious events are listed at a 0% frequency threshold.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 2, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
