A single-blinded randomized controlled study to assess the efficacy of twice daily application of sinecatechins 15% ointment when used sequentially with cryotherapy in the treatment of external genital warts.

OBJECTIVE: To evaluate the efficacy of sequential therapy of cryotherapy and sinecatechins 15% ointment BID versus cryotherapy alone in treatment of external genital warts (EGW).
METHODS: Forty-two subjects with at least two EGW lesions underwent cryotherapy to all lesions. One week following cryotherapy, subjects were randomized 1:1 to receive either no additional treatment or treatment with sinecatechins 15% ointment BID up to 16 weeks or until complete clearance. The total number of visible baseline and new EGW were recorded at each visit. Subjects were followed for a total of 65 weeks post-treatment.
RESULTS: There was a significant reduction in mean number of lesions from baseline after 16 weeks of treatment in the cryotherapy-sinecatechins ointment group compared to cryotherapy alone (-5.0 lesions vs -2.1 lesions respectively, P=0.07).
CONCLUSION: Cryotherapy plus sinecatechins 15% ointment BID resulted in a significant improvement in the reduction of EGW compared to cryotherapy alone. Clinicaltrials.gov registration identifier: NCT02147353.
