Primary Outcome Measures:
  • Regression of anogenital warts based on the total surface area involved by treated warts before, during, and after treatment. [ Time Frame: 3 months ] [ Designated as safety issue: No ]

Enrollment: 202
Study Start Date: August 2007
Study Completion Date: March 2009
Primary Completion Date: February 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Cohort 1
GS-9191 0.01% ointment
Drug: GS-9191 ointment
GS-9191 ointment (0.01%, 0.03%, or 0.1%) or placebo applied topically to anogenital warts for one or three cycles, each cycle lasting 5 consecutive nights of ointment application followed by 9 nights off-ointment. The strength of GS-9191 ointment is cohort-dependent, with escalation to higher dose cohorts dependent upon safety and tolerability in the previous cohort.
Experimental: Cohort 2
GS-9191 0.03% ointment
Drug: GS-9191 ointment
GS-9191 ointment (0.01%, 0.03%, or 0.1%) or placebo applied topically to anogenital warts for one or three cycles, each cycle lasting 5 consecutive nights of ointment application followed by 9 nights off-ointment. The strength of GS-9191 ointment is cohort-dependent, with escalation to higher dose cohorts dependent upon safety and tolerability in the previous cohort.
Experimental: Cohort 3
GS-9191 0.1% ointment
Drug: GS-9191 ointment
GS-9191 ointment (0.01%, 0.03%, or 0.1%) or placebo applied topically to anogenital warts for one or three cycles, each cycle lasting 5 consecutive nights of ointment application followed by 9 nights off-ointment. The strength of GS-9191 ointment is cohort-dependent, with escalation to higher dose cohorts dependent upon safety and tolerability in the previous cohort.
Active Comparator: Cohort 4
GS-9191 0.3%
Drug: GS-9191
GS-9191 ointment (0.3% or 1.0%) or placebo applied topically to anogenital warts for one or three cycles; each cycle consists of dosing occuring over a 5-night period with ointment application on nights 1, 3 and 5 followed by a 9-day off-ointment period. The strength of GS-9191 ointment is cohort-dependent, with escalation to higher dose cohorts dependent upon safety and tolerability in the previous cohort.
Active Comparator: Cohort 5
GS-9191 1.0%
Drug: GS-9191
GS-9191 ointment (0.3% or 1.0%) or placebo applied topically to anogenital warts for one or three cycles; each cycle consists of dosing occuring over a 5-night period with ointment application on nights 1, 3 and 5 followed by a 9-day off-ointment period. The strength of GS-9191 ointment is cohort-dependent, with escalation to higher dose cohorts dependent upon safety and tolerability in the previous cohort.
Placebo Comparator: Cohorts 1, 2, 3, 4 & 5
Placebo in all cohorts
Drug: Placebo
