Brief Summary:
The purpose of the study is to determine the absorption and systemic pharmacokinetics of AN2690 following daily application to all ten (10) toenails for 28 days.

Condition or disease Intervention/treatment Phase
Onychomycosis Drug: AN2690 Phase 2

Detailed Description:
A single center, open-label, multiple-dose study design will be used. Planned enrollment is 20 subjects to complete 15. Subjects must have a clinical diagnosis of onychomycosis of each great toenail and a clinical diagnosis of onychomycosis of six of the remaining toenails.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 20 participants

Drug Information available for: Tavaborole

Intervention Details:
  • Drug: AN2690
    AN2690 7.5% Solution, once daily for 28 days

Primary Outcome Measures :
  1. Plasma concentration of AN2690 in plasma and the concentration of AN2690 in urine over time [ Time Frame: Days 0, 1, 14, 15, and 28 ]

Secondary Outcome Measures :
  1. Efficacy measures of linear toenail growth, fungal culture results, KOH results, and clear toenail growth [ Time Frame: Days 0, 14, 28, and 42 ]
  2. Safety and tolerance assessed by application site reactions, adverse events, vital signs, physical examinations, and 12-lead EKG [ Time Frame: Days 0-28, and 42 ]
