Description
Inclusion Criteria:
Subjects must meet all of the following criteria to be included in the study:
- Must be able to comprehend and willing to sign an informed consent form (ICF).

- Must be at least 18 years of age.
Must have a minimum of 5 eligible facial, truncal, intertriginous, or extremity SKTLs. A maximum of 10 SKTLs will be targeted for treatment. An eligible SKTL must :
- Have one or more of the following clinical features throughout the entirety of the lesion consistent with SKs: stuck-on, sharply demarcated, warty, waxy, scaly, milia-like cyst, tan to black
- For subjects randomized for eligibility assessment with dermoscopy, SKs must also have one or more of the following dermoscopy features throughout the entirety of the lesion: crypts (comedo-like openings), milia cysts, hairpin vessels with white halo, sharp demarcation, blue-white pigmentation/veil as long as milia and crypts are present within, more than one color, cerebriform structure (network-like pattern/gyri and sulci/ridges and fissures/fat fingers), irregular vessels (inframammary only), granularity at periphery, stalactite/Tsingy pattern, plate-like/fractured pattern (Simionescu et al., 2012)
- Have a Physician's Lesion Assessment (PLA) of 2 (a thickness that is ≤1mm)
- Have a greatest diameter that is >5mm but ≤15mm
- Be a discrete, well-defined, separate lesion
- Not be covered with hair which, in the Investigator's opinion, would interfere with the study gel treatment or the study evaluations
- Not be pedunculated
- Not be on the eyelid
- Not be within 5mm of the orbital rim
- Must be free of any known disease state or physical condition which, in the Investigator's opinion, might impair evaluation of any SKTL or which exposes the subject to an unacceptable risk by study participation.
- Must be willing and able to follow all study instructions and to attend all study visits.
- Must be willing to have all partial, incompletely, or non-responding SKTLs removed surgically by shave excision during the final visit.
Exclusion Criteria:
Subjects meeting any of the following criterion will be ineligible and excluded from this study:

- SK lesions that are clinically atypical and/or rapidly growing in size or number.
- SK lesions that have any of the following features indicative of malignancy under dermoscopy: pinpoint vessels, smooth blue-white pigmentation/veil without milia or crypts within, hairpin vessels without white halo, white artifacts, irregular vessels (except for inframammary lesions). Additionally, for lesions randomized to dermoscopy, SK lesions must not have a moth-eaten border or fingerprint structures indicative of lentigos or a network pattern indicative of a melanocytic lesion.

- Sunburn; currently
- A pre-malignancy (e.g., actinic keratosis); currently
- Body art (e.g., tattoos, piercing, etc.); currently

- Any current skin disease (e.g., psoriasis, atopic dermatitis, eczema, sun damage, etc.), or other condition(s) (e.g., sunburn, excessive hair, open wounds, lupus, photosensitive disorders etc.) 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.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Superiority of active over vehicle as measured by the proportion of all SKTLs (Seborrheic Keratosis Target Lesion) that achieve a PLA score of 0
Time Frame: Screening, Baseline, Week 2, Week 4, Week 6, Week 8, Week 10, Week 12, and Week 16
|
The PLA is an Investigator assessment of SK lesion severity based on presence of SK and the thickness of the SK lesion. The PLA will be determined for each SKTL at all clinic study visits from Visit 1/Screening to Visit 9/Last Visit. Physician's Lesion Assessment Grade Descriptor 0 Clear: no visible seborrheic keratosis lesion
|
Screening, Baseline, Week 2, Week 4, Week 6, Week 8, Week 10, Week 12, and Week 16
|
Safety and Tolerability as evaluated by assessment of the severity of the signs and symptoms of Application Site Reactions (ASRs) of Seborrheic Keratosis
Time Frame: Through week 16 (Visit 9)

Application site reactions will be evaluated based on the scores for erythema, edema, exudation, erosion/ulceration, hyperpigmentation, and hypopigmentation by the Investigator, and the additional symptoms of pain, burning, stinging, and pruritus.
Scale 0=None, 1=slight, 2=Moderate, 3=Significant with 0 being the minimum value and 3 being the maximum value, with a higher value indicating higher severity.
