DEVICE DESCRIPTION

The Intranasal Tear Neurostimulator is a non-surgical, non-implantable device intended for the application of low level electrical stimulation to sensory neurons of the nasal cavities to acutely increase tear production in adult patients.

The device consists of four distinct non-sterile subassemblies, as listed below:

  1. Disposable Tips that insert up to 28mm into the nasal cavity and stimulate the target tissue of the intranasal skin and mucosa.

  2. A reusable Base which produces the electrical stimulation waveform.

  3. A reusable Charging Station which recharges the sealed battery inside the Base.

  4. A reusable Cover to protect the Disposable Tips.

Figure 1 provides a photograph of the device assembly; additional details for each component are discussed below.

Image /page/1/Picture/10 description: The image shows two different views of a device. On the left, the device is egg-shaped and blue, sitting on a white base next to a white box. The device has a white button with a plus and minus sign on it. On the right, there are two of the same devices, but they are hanging and have a different top.

FIGURE 1. THE OCULEVE INTRANASAL TEAR NEUROSTIMULATOR COMPONENTS

The device (Base) automatically turns off after one minute of stimulation. Alternatively, the device may also be turned off by holding down the "-" button for 2 seconds. The device will vibrate and the LEDs will turn off to indicate that the power has been switched off.

DISPOSABLE TIPS

The Disposable Tips connect to the Base and incorporates a silicone hydrogel that touches the inside of the nose, at a depth of up to 28 mm from the nasal columella (the skin separating the two nostrils), to provide stimulation. The Disposable Tips are removed and replaced daily; a separate Cover can be used to protect the Disposable Tips between uses.

BASE

The hand-held, battery-powered Base is the portion of the device which produces the required electrical output for stimulation. The Base produces a train of charge-balanced pulses that is patterned by modulating pulse amplitude, pulse width and pulse shape. The intensity of the stimulation is adjustable by using the (+) or (-) control buttons, which cycle the Base through six different levels (including zero, a non-stimulation level). The Base is held in the palm of the hand, allowing the patient to press one of two buttons to increase or decrease the intensity of stimulation. A series of LEDs on the Base illuminate to indicate powering the device on/off, the intensity level during use, and the charging of the Base's battery when connected to the Charging Station.

CHARGING STATION

The Charging Station provides a dock for recharging the battery located inside the Base. With the Disposable Tips removed, the Base can be inverted and placed onto the Charging Station.

COVER

The Cover is made of polycarbonate material and fits over the tips. The Cover can be used to protect the Disposable Tips between uses.

SUMMARY OF CLINICAL INFORMATION

The applicant conducted two pivotal clinical trials, OCUN-009 and OCUN-010, and a human factors usability study, OCUN-012, described below, which demonstrated that patients can use the Intranasal Tear Neurostimulator properly. The safety and effectiveness of the device was evaluated based upon the outcomes of studies OCUN-009 and OCUN-010. The two pivotal studies were found to be appropriate to support the action of the device effect (increased tear production during neurostimulation); however, therapeutic benefit, e.g., symptomatic relief from dry eye, was not assessed in the clinical studies.

OCUN-009

Pivotal clinical trial OCUN-009 was conducted to evaluate the safety and acute tear production during neurostimulation. The results of this trial provide reasonable assurance of safety and effectiveness of the device to increase tear production during stimulation. This two-day trial was a randomized, controlled, double-masked, study conducted at 2 sites in the United States. Fortyeight subjects (>22 years of age) received one active and two control treatments. On Day 1, participant eligibility was assessed. On Day 2, each study participant was subjected to three applications (1 active and 2 control) of the device in random order. Active treatment was performed using the Intranasal Tear Neurostimulator as intended. One control treatment used an active device that was "off-target" (i.e., extra-nasal). The other control treatment used a sham device. Tear production was assessed using the Schirmer test. which uses a paper strip that is

inserted into the eye for several minutes to provide a direct measurement of tear production in subjects due to the naso-lacrimal reflex. Schirmer scores and assessment of oxygen saturation (SpO2), heart rate (HR) and blood pressure (BP) were performed simultaneously during each application. Following completion of the 3 applications, subjects were assessed for visual acuity changes and underwent slit lamp and nasal examinations.

The primary effectiveness endpoint was the difference between unstimulated and stimulated tear production quantified by Schirmer scores. Based on measurements using the Schirmer test, there was an increase in tear production during electrostimulation. The average Schirmer score was reported for the active and two control applications. An average Schirmer score of 25.3 mm ± 10.7 was observed during active electrostimulation, compared with 9.2 mm ± 7.3 for the Sham control application (p
