Evaluation Study for the Efficacy and Safety of PinPointe FootLaser in Treatment for Onychomycosis
A Placebo Controlled, Randomized, Prospective Study to Evaluate the Efficacy and Safety of PinPointe FootLaser in Patients Who Have Failed Oral Terbinafine Treatment for Onychomycosis
The purpose of this study is to assess the clinical efficacy and safety of the PinPointe Foot Laser device for the treatment of patients with onychomycosis who have been previously treated with oral Terbinafine and failed.

This protocol is designed to demonstrate that the PinPointe FootLaser treatment is able to produce clinical improvement treating onychomycosis in patients who have previously taken Terbinafine and failed treatment. The duration of enrollment for each subject will be 2 years, with the expectation that this is the time period that will yield 100% reduction in the area of involved nail. Enrollment is competitive and we expect to enroll 40 patients at CHA.

The medical device that is the subject of this clinical trial is the PinPointe FootLaser, manufactured by NuvoLase, Inc. It is a pulsed Nd:Yag laser device that uses a proprietary pulse train, operating at 1064nm wavelength, with 100 μsec pulses. It received pre-market Section 510(k) clearance by the FDA and subsequent clearance for the treatment of onychomycosis in 2010.

Onychomycosis (OM), a fungal infection of the toes, is a major health problem around the world. It is estimated that there are more than 40 million sufferers with this condition in the USA. A recent European study showed that the prevalence of onychomycosis may be as high as 26.9%. Importantly, it is a particular problem that disproportionately affects diabetics. The main causative agent varies according to climate. Dermatophyte infections are common worldwide.

Preliminary in vitro and in vivo work has demonstrated the proof of principle that the PinPointe FootLaser device can kill microorganisms, including dermatophytes and other fungi, which infect the toenail. Based on these preliminary results, this study has been designed to demonstrate the efficacy and safety of the PinPointe FootLaser for clearing toenails, including those with onychomycosis.
