Measure
Sinecatechins 15% Ointment & Cryotherapy
Cryotherapy and then Sinecatechins 15% Ointment 1 week later. Sinecatechins 15% Ointment: Following cryotherapy, half of the subjects randomized to treatment with sinecatechins ointment twice daily starting one week after cryotherapy up to 16 weeks or until complete clearance.
Cryotherapy Alone
Cryotherapy standardized in all subjects and for all treated lesions: EGW lesions treated with 2 cycles, 5 seconds each, with a 5 second interval. All subjects treated with the same cryo-spray regimen.

SECONDARY outcome

Timeframe: at 24 week post-treatment period

To evaluate the efficacy of using combination cryotherapy-sinecatechins 15% ointment BID versus cryotherapy alone on EGW lesions via recurrence rates of previously treated EGW lesions in those subjects who achieved a complete response over a 24 week post-treatment period.

21/21 • Number of events 21 • Adverse event data were collected over 65 weeks
There were no serious adverse events related to the study medication reported during the study. All subjects experienced mild to moderate local site reactions (eg, any symptom of erythema, edema, scaling, crusting, and erosion which were not collected separately) that were related to both cryotherapy and/or sinecatechins ointment. There were no subject discontinuations or dose interruptions.
