ABSTRACT
The beginning of the end (BOTE) sign has been proposed to describe well-recognized clinical signs of inflammation (including erythema, induration, and scale) that predict imminent resolution of molluscum contagiosum (MC). This phenomenon has never been prospectively studied. An integrated analysis of two prospective, 12-week, randomized, double-blind clinical trials of topical nitric oxide-releasing SB206 gel evaluated an association between BOTE sign and MC lesion reduction. Of 707 randomized patients, ~80% exhibited BOTE signs regardless of treatment assignment. At week 12, MC lesion counts decreased from baseline by 50.7% for baseline BOTE+ versus 29.1% for BOTE- (P = 0.0015) vehicle-treated patients compared with a 63.3% decrease for baseline BOTE+ versus 51.7% for BOTE- (P = 0.0194) SB206-treated patients. Among vehicle-treated patients, 48 (22.3%) who were never BOTE+ had an 18.5% reduction from baseline in MC lesion counts versus a 34.0% reduction in 165 patients (76.7%) who experienced BOTE at any time, suggesting that the projected duration of lesion clearance for patients with 18-20 MC lesions is 15 months for BOTE- versus 6 months for BOTE+ patients. Patients who were both BOTE+ and treated with SB206 had the greatest reduction in MC lesion count. SB206 may trigger BOTE signs and shorten the duration of MC infection. The two studies whose data are analyzed in this study are registered at ClinicalTrials.gov with the identifiers NCT03927703 and NCT03927716.
