Study Groups

vehicle gel

The vehicle gel will be applied in appropriate amount evenly and gently in a thin-layer of gel by finger, not to exceed 0.2 g per administration (approximately 2 cm gel squeezed in length). Each dose of study drug is applied on the target lesion(s) and covered with an occlusive dressing for the entire day.

Group Type: PLACEBO_COMPARATOR

Vehicle gel

Intervention Type: DRUG

Topical application on the target lesion(s)once daily with occlusive dressing; a maximum of 3 times of administration of gel without exceeding 0.2 g per administration.

SR-T100 gel with 1.0% of SM

SR-T100 contains 1.0% SM. The gel will be applied in appropriate amount evenly and gently in a thin-layer of gel by finger, not to exceed 0.2 g per administration (approximately 2 cm gel squeezed in length). Each dose of study drug is applied on the target lesion(s) and covered with an occlusive dressing for the entire day.

Group Type: ACTIVE_COMPARATOR

SR-T100 gel with 1.0% of SM

Intervention Type: DRUG

Topical application on the target lesion(s)once daily with occlusive dressing; a maximum of 3 times of administration of gel without exceeding 0.2 g per administration.

SR-T100 gel with 2.3% of SM

SR-T100 contains 2.3%SM. The gel will be applied in appropriate amount evenly and gently in a thin-layer of gel by finger, not to exceed 0.2 g per administration (approximately 2 cm gel squeezed in length). Each dose of study drug is applied on the target lesion(s) and covered with an occlusive dressing for the entire day.

Group Type: ACTIVE_COMPARATOR

SR-T100 gel with 2.3% of SM

Intervention Type: DRUG

5. Patient or the legally acceptable representative of patient under 20 years of age, is willing and able to provide written informed consent.

6. Patient agrees not to use wart-removing product/modality (prescription or over-the-counter) other than the study product during the course of the study; and is willing to refrain from using cosmetics or other topical products in the treatment area for the duration of the study.

7. Any non-target CW receiving wart-removing procedures including cryotherapy and surgical therapy should be at least 5 cm apart from the target lesions.

8. Patient is free of any systemic or dermatologic disorder, which, in the opinion of the investigator, will interfere with the study results or increase the risk to the patient.

9. Patient is judged to be in good health based upon the results of physical examinations (PEs), medical history, and safety laboratory tests.

10. Patient in good general health condition (performance status ≤ 2 Eastern Cooperative Oncology Group (ECOG)).

11. Patient agrees to be photographed of the CW target lesion(s) and used of such data as part of the study package.

12. Female patient of childbearing potential should have a negative urine or serum pregnancy test at Screening day, and is willing to use effective contraception during the study.

Exclusion Criteria

1. The treatment area is located in any of the following areas: the eye area (including eyelids), lips, mouth cavity, nasal cavity,inner ear, soles of the feet, underneath the nails, and the anogenital area.

2. Patient had participated in a clinical study within 30 days prior to the Randomization visit, or is currently participating in another clinical study.

3. Patient had used any wart-removing product/modality in the treatment area within 30 days prior to the Randomization visit or received cryotherapy in the treatment area within 60 days prior to the Randomization visit.

4. Patient who has immune-compromised conditions, have required or will require systemic intake of immunosuppressive or immunomodulatory medication (oral or parental corticosteroids are included) within 30 days prior to the Randomization visit or during the course of the study.

1. Clinically significant peripheral vascular disease based on medical history.

2. Current uncontrolled infection, current skin infections and/or skin disorder in the treatment area other than CW and/or in the area surrounding the warts that may confound or affect study assessment procedure of the study endpoints.

3. Chronic or acute medical condition that, in the opinion of the investigator, may interfere with the study results or place the subject at undue risk (including human immunodeficiency virus, systemic lupus erythematosis, active viral hepatitis, etc.).

6. Patient is pregnant, plan to become pregnant, or is breastfeeding.
