  • Clear Nail Growth of the Targeted Toenail [ Time Frame: Day 360 ] [ Designated as safety issue: No ]
    Clear nail was measured on digital images as the distance in millimeters from the proximal nail fold to the proximal limit of the disease as marked by the Investigator. New Clear Nail Growth (CNG) was calculated from the clear nail measurements.
  • Mycological Evaluations (Negative Potassium Hydroxide (KOH) and Negative Fungal Culture) Compared to Baseline [ Time Frame: Day 90 ] [ Designated as safety issue: No ]
    Number of subjects with negative KOH, and number of subjects with negative fungal cultures.
  • Mycological Evaluations (Negative KOH and Negative Fungal Culture) Compared to Baseline [ Time Frame: Day 180 ] [ Designated as safety issue: No ]
    Number of subjects with negative KOH, and number of subjects with negative fungal cultures.
  • Mycological Evaluations (Negative KOH and Negative Fungal Culture) Compared to Baseline [ Time Frame: Day 270 ] [ Designated as safety issue: No ]
    Number of subjects with negative KOH, and number of subjects with negative fungal cultures.
  • Mycological Evaluations (Negative KOH and Negative Fungal Culture) Compared to Baseline [ Time Frame: Day 360 ] [ Designated as safety issue: No ]
    Number of subjects with negative KOH, and number of subjects with negative fungal cultures.
  • Length of Time to Clinical Evaluation of Clear or at Least 5 mm of CNG [ Time Frame: Baseline to 360 ] [ Designated as safety issue: No ]
    Length of time to clinical evaluation of clear or at least 5 mm of CNG.
  • Clear nail growth of the targeted toenail [ Time Frame: Days 360 ] [ Designated as safety issue: No ]
  • Mycological evaluations (negative KOH and negative fungal culture) compared to baseline [ Time Frame: Day 90, 180, 270 and 360 ] [ Designated as safety issue: No ]
  • Length of time to clinical evaluation of clear or at least 5 mm of CNG [ Time Frame: Baseline, Days, 14, 30, 60, 90, 120, 150, 180, 210, 240, 270, 300 and 360 ] [ Designated as safety issue: No ]

Safety and Efficacy Study of Subjects With Onychomycosis of the Great Toenail
An Open-Label, Rising Multiple-Dose, Multi-Center Study to Evaluate the Safety and Efficacy of Topically Applied AN2690 5.0% and 7.5% Solution for the Treatment of Adult Subjects With Onychomycosis of the Great Toenail

The purpose of the study is to determine the safety and efficacy of 5.0% AN2690 Solution in the treatment of distal, subungual onychomycosis of the great target toenail.

In this cohort, only the targeted great toenail identified at Baseline prior to the commencement of treatment from culture results collected at the Screening visit were evaluated for primary efficacy whereas all treated toenails were evaluated for safety. At each visit, the investigator was asked to make a clinical evaluation of the targeted great nail, marking whether or not they considered the nail to be clear of onychomycosis. This evaluation was the basis for determining whether or not study medication should be dispensed at the visit.

This record includes information only for Cohort 3 (5% solution) of the study. Cohorts 1 and 2, are described in NCT00679523 (7.5% solution). No comparison was made between Cohorts 1&2 and Cohort 3.
