{0}------------------------------------------------ SEP 1 4 2005 K050729 #### 510(k) SUMMARY ## Submitted by: Kim B. Kracke Senior Manager, Regulatory Affairs Alcon Research, Ltd. 6201 South Freeway Fort Worth, Texas 76134-2099 (817) 551-8338 (Phone) (817) 551-4630 (Fax) #### Device Name: Proprietary Name: ALCON® Multi-Purpose Disinfecting Solution Common Name: Soft (Hydrophilic) Contact Lens Care Solution Classification Name: Under 21 CFR §886.5928 titled Soft (hydrophilic) contact lens care products, this solution is classified as a Class II - Special Controls Product. ## Indications for Use: For use in the daily cleaning, conditioning, rinsing, removing protein deposits, chemical (not heat) disinfection, and storage of silicone hydrogel and soft (hydrophilic) contact lenses as recommended by your eye care practitioner. ALCON® Multi-Purpose Disinfecting Solution can also be used with OPTI-FREE® SUPRACLENS® Daily Protein Remover. ## Description: ALCON® Multi-Purpose Disinfecting Solution is a sterile, buffered, isotonic, aqueous solution containing sodium citrate, sodium chloride, sodium borate, propylene glycol, a proprietary dual action conditioning system (Tetronic® 1304t, nonanoyl {1}------------------------------------------------ ethylenediaminetriacetic acid) with POLYQUAD® (polyquaternium-1) 0.001% and ALDOX® (myristamidopropyl dimethylamine) 0.0005% as preservatives. * Tetronic® is a trademark of BASF. ## Substantial Equivalence: ALCON® Multi-Purpose Disinfecting Solution is substantially equivalent in terms of its actions and indications for use to Bausch & Lomb ReNu Multi-Purpose Solution. ALCON® Multi-Purpose Disinfecting Solution meets the guidelines set forth in FDA 's May 1, 1997 Guidance for Industry; Premarket Notification 510(k) Guidance Document for Contact Lens Care Products. ## Safety and Effectiveness: #### Cleaning Effectiveness Studies Laboratory studies were conducted with ALCON® Multi-Purpose Disinfecting Solution. The purpose of these studies was to evaluate passive cleaning using a no rub regimen with silicone hydrogel and soft contact lenses and the ability to clean laboratory deposited lenses. The results indicate that ALCON® Multi-Purpose Disinfecting Solution is effective at passively cleaning all soft contact lenses including silicone hydrogel lenses. This data is supported by results of clinical evaluations. Additional laboratory studies conducted with OPTI-FREE® SUPRACLENS® Daily Protein Remover in combination with ALCON® Multi-Purpose Disinfecting Solution indicate improved cleaning efficacy on soft contact lenses. The cleaning efficacy of the solution has been evaluated through the determination of the Critical Micelle Concentration (CMC). The surfactant concentration is well above the CMC, which ensures the effective cleaning function of the product. {2}------------------------------------------------ #### Compatibility Studies Lens compatibility studies performed with silicone hydrogel and FDA Groups I and IV contact lenses show that ALCON® Multi-Purpose Disinfecting Solution is compatible with all soft contact lenses including silicone hydrogels. #### Wettability Studies In vitro and ex vivo wettability studies were carried out on ALCON® Multi-Purpose Disinfecting Solution versus Bausch & Lomb ReNu MultiPlus Multi-Purpose Solution marketed disinfection product. The in vitro study results correlated with the ex vivo study data where the ALCON® Multi-Purpose Disinfecting Solution formulation showed significantly lower wetting angles indicating excellent wettability. Comparatively, the Bausch & Lomb ReNu Multi-Purpose Solution product showed high contact angles in the plateau region of the in vitro wetting data and this correlated with the ex vivo data where high wetting angles were observed. All of the ex vivo wetting angles were observed after eight hours of contact lens wear. # Microbiology Studies A series of studies based on the FDA's May 1, 1997 Guidance for Industry; Premarket Notification 510(k) Guidance Document for Contact Lens Care Products, EN ISO 14729:2001 Ophthalmic optics – Contact lens care products – Microbiological requirements and test methods for products and regimens for hygienic management of contact lenses, the ANSI Contact Lens Care Products Standard, and EN ISO 14730:2000 Ophthalmic optics -Contact lens care products - Antimicrobial preservative efficacy testing and guidance on determining discard date were completed to demonstrate the microbiological efficacy of ALCON® Multi-Purpose Disinfecting Solution. The product meets the Stand Alone Antimicrobial Activity of the above standards both in the presence and absence of organic soil. The product passes the Regimen Criteria in the presence of soil when tested according to the directions for use. In addition, results showed that the combination of ALCON® Multi-Purpose Disinfecting Solution with OPTI-FREE® SUPRACLENS® Daily Protein Remover meets the primary criteria of the Stand Alone test. {3}------------------------------------------------ # Biocompatibility ALCON® Multi-Purpose Disinfecting Solution meets the guidelines set forth in FDA's May 1, 1997 Guidance for Industry; Premarket Notification 510(k) Guidance Document for Contact Lens Care Products. Based on the results of the comprehensive preclinical evaluations, ALCON® Multi-Purpose Disinfecting Solution is safe for the consumer under the recommended use conditions, as well as under conditions of reasonably foreseeable misuse. # Clinical Studies A series of clinical studies was conducted using ALCON® Multi-Purpose Disinfecting Solution. A three-month clinical study with asymptomatic soft (hydrophilic) lens wearers, a one-month study with silicone hydrogel lens wearers and a one-month study with symptomatic soft (hydrophilic) lens wearers were conducted to demonstrate the safety and efficacy of the ALCON® Multi-Purpose Disinfecting Solution regimen with silicone hydrogel and soft (hydrophilic) contact lenses. The control products were the Bausch & Lomb ReNu MultiPlus Multi-Purpose Solution regimen and the Advanced Medical Optics Complete MoisturePLUS Multi-Purpose Solution regimen used according to the current approved label. The safety and efficacy of the ALCON® Multi-Purpose Disinfecting Solution regimen were clinically acceptable and similar to the marketed comparator regimens when used according to the approved label. Lenses cared for with the ALCON® Multi-Purpose Disinfecting Solution regimen had statistically lower levels of lens deposits than the control regimens. In at least one of the three studies, subjects assigned to the ALCON® Multi-Purpose Disinfecting Solution regimen had statistically lower corneal staining and significantly improved comfort (on some measures of comfort) compared to one of the predicate product regimens. An additional clinical study was conducted to evaluate the effect of the ALCON® Multi-Purpose Disinfecting Solution regimen on the wetting characteristics of soft (hydrophilic) contact lenses. (This study is also cited above in the Wettability Studies section.) The control product was Bausch & Lomb ReNu MultiPlus Multi-Purpose Solution regimen used according to the current approved label. Lenses were rinsed and disinfected overnight in the assigned multi-purpose solution. The differences in lens wettability after wear between ALCON® Multi-Purpose Disinfecting Solution and Bausch & Lomb ReNu Multi-Purpose Solution were statistically significant (p ≤ 0.0001) in favor of ALCON® Multi-Purpose Disinfecting Solution. {4}------------------------------------------------ Image /page/4/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.
