### 8. Clinical data

Clinical studies were performed to establish the safety and efficacy of the Biomedics® 52 1-Dav lenses with an in-process manufacturing change. The purpose of the clinical investigation was to verify that the change made in the manufacturing process to an unextracted process, substantiated by safety toxicity testing data results, do not raise additional questions of safety or effectiveness.

The study was designed as an open-label, prospective, concurrent cohort control, randomized clinical trial. Subjects were recruited based upon specified inclusion criteria to assure that the appropriate subject population samples were included and inappropriate subjects were excluded. Scheduled follow-up visits were planned for the 1-Week, 2-Week and 4-Week visit intervals based upon the date the subject was dispensed the Test or Control lenses. No subjects were discontinued prior to completion in this investigation. No adverse events were reported for either the Test or Control cohort through the study period.

Thirty-six (36) subjects (72 eyes) were enrolled into the study at three (3) investigational sites. All of the 36 subjects were determined to be eligible to enter the study and were dispensed either the Test or the Control lenses based upon a randomization schedule provided to the site.

The distribution of age and gender of the subjects enrolled into the study by cohort is shown below.

| | Distribution of Age and Gender | | |
|---------------------|--------------------------------|---------|--------|
| | Test | Control | Totals |
| Female Subjects | 19 | 10 | 29 |
| Male Subjects | 5 | 2 | 7 |
| Ratio F/M | 3.8:1 | 5:1 | 4.1:1 |
| Average Age (years) | 36.0 | 38.8 | 36.9 |

## Safety Results:

Safety is demonstrated if the test lens complications are substantially equivalent in frequency and severity to the control lens complications.

- 1. Permanent decreases in BCVA: There were no reports of 2-line decreases in best corrected Snellen visual acuity for any of the Test or Control cohort eyes.

- Persistent corneal staining of Grade 3 or 4 at two or more follow-up visits: There were no reports 2. of Grade 3 or 4 staining for either the Test or the Control cohort eyes.
- Neovascularization more than 1.5mm and/or more than 1.0mm in 3 or more quadrants: There was 3. no neovascularization reported of greater than 1.5mm in any quadrant. The incidence of neovascularization reported for the Completed Test and Control cohort eyes remained stable throughout the period of the study.
- Persistent hyperemia of Grade 3 or 4 at two or more follow-up visits: No Grade 3 or 4 limbal or 4. bulbar hyperemia was reported during the period of the study for any Test or Control cohort eyes.
- Peripheral or central ulcerative keratitis: No peripheral or central ulcerative keratitis was reported 5. during the period of the study for any Test or Control cohort eyes.
- Infiltrates of Grade 2 or worse: No infiltrates were reported during the period of the study for any 6. Test or Control cohort eyes.
- 7. Subrective symptoms, problems or complaints: Subjective symptoms were reported for both the Test and the Control eves over the course of the study. The areas where the Test and Control cohorts presented with differences were in discomfort and blurred vision.

Discomfort was reported more frequently and with greater severity for the Test cohort eyes with 12.5% of the follow-up examinations for Test eyes resulting in a report of discomfort with an average severity of 2.1 out of 4.0. This is in contrast to the Control cohort eyes where discomfort was reported for 7.3% of the follow-up examinations with an average severity of 1.1 out of 4 0.

Blurred vision was reported more frequently for the Control cohort eves with 6.3% of the follow-up examinations for Control eves resulting in a report of blurred vision with an average severity of 1.7 out of 4.0. This is in contrast to the Test cohort eyes where blurred vision was reported for 1.6% of the follow-up examinations with an average severity of 1.0 out of 4.0.

The findings for symptoms, problems and complaints do not indicate any safety issues with the Test lenses when compared to the Control lenses. The symptom of discomfort was not related to objective (slit lamp) findings for the Test cohort eyes and does not by itself indicate any safety concerns.

Both the Test and the Control cohort eyes had similar outcomes in the evaluation of the safety variables. Very few complications were reported during the study and most were mild and transient. Based upon the safety criteria established in the study protocol and reviewed above, the Test lens demonstrates equivalent safety when compared to the Control lens.

## Visual Acuity Results:

The comparison of the beginning and ending lens visual acuties within and between the Test and the Control cohort eyes provides evidence that the Test lens is safe and effective with respect to lens visual acuity. Both the Test and Control lens visual acuities are essentially the same at the final examination.

| Completed Test Eyes | 83.3% | 84.8% |
| Completed Control Eyes | 54.2% | 83.3% |

### Average Wearing Time:

Based upon the average lens wearing times reported by the Test and Control subjects, both cohorts were achieving acceptable and similar average daily wearing times. For the Test cohort the was 12.8 hours per day to 13.2 hours per day over the period of the study. For the Control cohort the average wearing time was 13.1 hours per day to 13.3 hours per day over the period of the study.

## Lens Deposits over course of the study:

Over the period of the study the Test and the Control cohort lenses were reported to have similar rates, Test 12.5% and Control 11.1%, with the Test eves reporting 1.4% of the lenses as having medium deposits and the Control eyes only reporting light deposits.

## Efficacy Summary:

- 1. The proportion of subjects in each group (Test or Control) successfully completing the protocol specified study duration: All of the Test and Control cohort subjects completed the 1 month study period. No subjects were discontinued for any reason.
- 2. The percentage of lens visual acuties of 20/20 and the percentage of lens visual acuittes of 20/30 or Better: The percentage of Completed eyes reporting visual acuities of 20/20 or better at the final study visit was 84.8% for the Test cohort eyes and 83.3% for the Control eves. Both of these proportions are greater than those measured at the study. The percentage of Completed eves reporting visual acuities of 20/30 or better at the final study visit was 100% for the Test cohort eves and 100% for the Control cohort eyes. The percentage of Test eyes reporting VAs of 20/30 at the final visit met the expectations set at the inception of the study.
- 3. Overall, the visual performance of the Test lens was similar to the performance of the Control lens.

## Conclusions:

These conclusion are based upon the review of the data reported during the 1 month evaluation of the safety and efficacy of the Biomedics® 52 1-Day (ocufilcon B) soft (hydrophilic) contact lenses manufactured under a process change used following a daily disposable contact lens regimen.

The results of the slit lamp examinations indicate that the Test lens performs at least as well as the Control lens in terms of safety. Visual acuities and ocular health were all maintained during the study. Except for

discomfort, most of the symptoms, problems and complaints were reported at similar rates between the Test and the Control cohorts. The completion of all of the subjects recruited for the study and the excellent visual acuity results demonstrate the efficacy of the Test lens during the study.

The difference in the reports and severity of the symptom discomfort also suggest that the Test lens is associated with excessive discomfort for some of the Test subjects. The findings of this study demonstrate that the Test lens performs equivalently in terms of safety and efficacy when compared to the Control lens cohort.
