  14. Patients have history of allergy or sensitivity to Solanum undatum plant extract, SM, or SR-T100 gel excipients including carbomer, propylene glycol, and triethanolamine.
  15. Patients with prohibited pre-medication or procedures shown below:

    1. Physical modalities, such as laser ablation, electrocautery or cryotherapy, for genital warts treatment on treated area within 4 weeks prior to randomization visit.
    2. Topical administered medication for genital warts treatment, such as polyphenon E, podophyllotoxin, imiquimod, or 5-fluorouracil (5-FU), within 12 weeks prior to randomization.

SR-T100 gel with 1.0 % SM

SR-T100 gel with 2.3% SM

Arm Description

vehicle gel is used as a control group. The maximum daily dosage is 3 times of 400+/-100 mg of gel, meaning no more than 1,500 mg of gel. Patients should wash thoroughly their hands, then squeeze until 4 cm of gel is out from the aluminum tube. Apply gel on the lesion warts and on the clinical normal skin on the treated area.

5. Study Description

Brief Summary
To evaluate the efficacy of SR-T100 gel by observing total clearance rate of treated baseline EGW(s) on the treated area.
Detailed Description
A double-blind, randomized,vehicle-controlled, parallel-group, and dose-ranging study to evaluate the efficacy and safety of SR-T100 gel in patients with EGW(s). The primary efficacy endpoint will be defined as the proportion of patients whose baseline EGW(s) on the treated area achieve total clearance. The efficacy of SR-T100 gel in prevention of new EGW(s) occurrence will be evaluated. Distinct to existing medications for EGWs, SR-T100 gel possesses characteristics of high safety and low LSR causality. SR-T100 gel will be administered on EGW lesion(s) for clearance and on the surrounding clinical normal skin for prevention of new EGW(s) occurrence.
