Device Story

OptiChamber Diamond is a valved holding chamber (VHC) used with pressurized metered dose inhalers (pMDIs) to assist patients unable to coordinate pMDI actuation with inhalation. Device captures aerosol cloud from pMDI; larger particles removed via impaction on chamber walls and gravity-driven sedimentation. Components include mouthpiece, chamber, adapter with inhalation flow alert, exhaust valve, inhalation valve, valve retaining ring, and cap. Constructed from antistatic plastic. Used in homes, hospitals, and clinics by patients under physician care. Provides visual/mechanical assistance for drug delivery; improves medication deposition by slowing aerosol velocity and allowing time for inhalation. No active electronic components; flow alert is mechanical.

Clinical Evidence

No clinical data. Substantial equivalence established via in vitro bench testing using a Next Generation Impactor (NGI) at 15 and 30 LPM to simulate pediatric and adult breathing patterns. Three inhaler formulations (albuterol, fluticasone propionate, ipratropium bromide) were tested. Performance metrics included Total Emitted Dose (ED), Fine Particle Dose (FPD), Fine Particle Fraction (FPF), Mass Medium Aerodynamic Diameter (MMAD), and Geometric Standard Deviation (GSD).

Technological Characteristics

Antistatic plastic construction; valved holding chamber design; mechanical inhalation flow alert; includes mouthpiece and optional masks (Small, Medium, Large LiteTouch). Operates via passive aerosol impaction and sedimentation. No external energy source. Non-sterile.

Indications for Use

Indicated for patients under physician care requiring administration of aerosolized medication from pressurized metered dose inhalers (pMDIs). Population: patients aged 0 to 18 months (with small mask), 1 to 5 years (with medium mask), and 5 years and older (with large mask or mouthpiece).

Regulatory Classification

Identification

A nebulizer is a device intended to spray liquids in aerosol form into gases that are delivered directly to the patient for breathing. Heated, ultrasonic, gas, venturi, and refillable nebulizers are included in this generic type of device.

#### Predicate Device Information: 3.

Identification of legally marketed device which we claim substantial equivalence to: AeroChamber Plus Z-Stat Valved Holding Chamber K052332 Trudell Medical International. 725 Third Street London, Ontario Canada, N5V 5G4

#### Device Description: 4.

The OptiChamber Diamond Valved Holding Chamber (VHC) is a Class II device. It is intended to be used in combination with most pressurized Metered Dose Inhalers (pMDIs) to assist in respiratory drug delivery.

The OptiChamber Diamond Valved Holding Chamber is a device utilizing the same operating principles as the AeroChamber Plus Z-Stat Valved Holding Chamber (K052332). Both the AeroChamber Plus Z-Stat and the OptiChamber Diamond are available with and without mask.

The valved holding chamber (VHC) is designed to assist patients who cannot correctly coordinate actuation of the pressurized metered dose inhaler (pMDIs) with inhalation. The VHC works by 'holding' the aerosol cloud emitted from the pMDI inside the chamber so that the larger aerosol particles are removed from the aerosol cloud by impaction into the chamber walls and sedimentation under the influence of gravity.

The OptiChamber Diamond Valved Holding Chamber is made of antistatic plastic materials alleviating any need to wash prior to first use. OptiChamber Diamond is comprised of: the mouthpiece, the chamber, the adapter (end cap) with inhalation flow alert, the exhaust valve, the inhalation valve, the valve retaining ring, and the cap.

## 5. Intended Use:

The OptiChamber Diamond Valved Holding Chamber device is intended to be used by patients who are under the care or treatment of a physician or licensed healthcare professional. The device is intended to be used by these patients to administer aerosolized medication from most pressurized Metered Dose Inhalers. The intended environments for use include the home, hospitals and clinics.

For Single Patient Use

Recommended Patient Population:

OptiChamber Diamond: Age 5 and up

OptiChamber Diamond with Small LiteTouch mask: 0 to 18 months

{2}------------------------------------------------

OptiChamber Diamond with Medium LiteTouch mask: 1 to 5 years OptiChamber Diamond with Large LiteTouch mask: 5 years +

### 6. Comparison to Predicate Devices:

The OptiChamber Diamond Valve Holding Chamber and the predicate device (AeroChamber Plus Z-Stat Valved Holding Chamber (K052332)) are indicated for the same intended use and their performance characteristics are substantially equivalent. Both the AeroChamber Plus Z-Stat and the OptiChamber Diamond are available with and without mask.

The LiteTouch medium mask was approved under K100285.

# 7. Discussion of Non-Clinical Tests Performed for Determination of Substantial Equivalence

A pressurized Metered Dose Inhaler (pMDI) alone and a pMDI with the OptiChamber Diamond valved holding chamber (VHC) were tested utilizing a Next Generation Impactor (NGI) with a custom flat plate adapter and operated at 15 and 30 liters per minute (LPM). The 15 liters per minute was chosen to simulate pediatric breathing pattern and the 30 liters per minute was chosen to simulate adult breathing pattern (reference: Breathing patterns, K. Nikander, J. Denyer, Eur Respir Rev 2000; 10: 76, 576-579). The pMDI was actuated 10 times into each device. Deposition of drug on various locations of the NGI was qualified using HPLC assays.

MMAD, GSD, FPD, and FPF results were determined using CITDAS (reference: Performance Verification of Copley Inhaler Testing Data Analysis Software (CITDAS), Respiratory Drug Delivery Europe 2009 -Krebs et al.) software version 3.10. Fine particle dose (FPD) was presented as 3 categories: greater than 4.7um, less than or equal to 4.7um and less than or equal to 1.0um. Fine particle fraction (FPF) is defined as the fraction of dose entering the impactor equal to or less than 4.7um.

Three inhaler formulations (albuterol, fluticasone propionate and ipratropium bromide) were evaluated.

{3}------------------------------------------------

### Definitions:

- ED = Total Emitted Dose: Total amount of drug from VHC + USP Throat + NGI components + Filter
- FPD = Fine Particle Dose: amount of drug entering the impactor with an acrodynamic diameter between specific limits.
- FPF = Fine Particle Fraction: a fraction of dose entering the impactor with an aerodynamic diameter of ≤ 4.7um
- MMAD = Mass Medium Aerodynamic Diameter: The geometric mean aerodynamic diameter. Fifty per cent of particles by weight will be smaller than the MMAD, 50% will be larger.
- GSD = Geometric Standard Deviation: A measure of dispersion in a lognormal distribution always greater than or equal to 1.0.

## 8. Discussion of Clinical Tests Performed:

Not Applicable.

### 9. Conclusions:

We have demonstrated that the OptiChamber Diamond Valved Holding Chamber is substantially equivalent to the predicate device, the AeroChamber Plus Z-stat Valved Holding Chamber, through in Vitro Testing. The two devices are also substantially equivalent in terms of their features, operating principle, and indications for use.
