Trial Information

A Double-Blind, Vehicle Controlled, Randomized, Phase II Study of SR-T100 Gel on External Genital Warts/Condyloma Acuminate (EGWs)

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.

Inclusion Criteria:

1. Male or female; aged ≥ 20 years old.

2. Patients who accept to enter the study by signing written informed consent.

3. Each patient has 1 to 10 clinically diagnosed EGW(s). If patient has only 1 genital
wart, the diameter of the genital wart must be no less than 5 mm.

4. Female patients have lesion(s) on labia majora, labia minora, clitoris and/or groin.

5. Male patients have lesion(s) on glans, shaft and/or foreskin.

6. Each patient has at least 1 histologically proved EGW.

7. Patients agree to apply the study medication on "clinical diagnosed lesion(s)" with
occlusive dressing(s) once daily for at least 20 hours per day and "clinical normal
skin on the treated area" thrice daily without occlusive dressing.

8. Patients allow diagrammed mapping and photography on genital warts. And patients
agree to be used of these data as part of the study data package.

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

10. Female patients with child-bearing potential must take reliable contraception
method(s) during the participation of the study.

11. Patients must agree to use effective boundary barrier for birth control and
re-infection of EGW

Exclusion Criteria:

1. Patients with peri-anal warts.

2. Male patients with warts on scrotum or perineum.

3. Patients with other genital infections.

4. Patients with internal genital warts (such as urethral, intra-vaginal, cervical,
rectal, or intra-anal genital warts).

5. Patients with active systemic infections.

6. Patients with other genital diseases that may confound evaluation and treatment for
genital warts.

7. Patients with immuno-compromised medical condition.

8. Patients have received investigational drug prior to 30 days of randomization visit.

9. Patients with cancer or cancer history within 5 years of the randomization visit.

10. Patients have on-going human papilloma virus (HPV) infection other than genital area.

11. Patients with human immunodeficiency virus (HIV), venereal disease research
laboratory (VDRL), or treponema pallidum particle agglutination assay (TPHA) positive

12. Female patients have high-grade pathology in Papanicolaou smear tests based on
Bethesda system.

13. Female patients are pregnant or lactating.

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

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.

3. Medications of cytotoxic, immunomodulator (inhaled and topical steroid not on
ano-genital areas are not prohibited), systematic antiviral agent in 4 weeks
prior to randomization visit.
