Details and patient eligibility

About

This will be a multi-site, bilateral, dispensing, randomized, controlled, double-masked, 2×2 crossover study to evaluate ocular physiological response.

Enrollment: 67 patients

Sex: All

Ages: 18 to 39 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

Potential subjects must satisfy all of the following criteria to be enrolled in the study.

The subject must:

1. Read, understand, and sign the STATEMENT OF INFORMED CONSENT and receive a fully executed copy of the form.

2. Appear able and willing to adhere to the instructions set forth in this clinical protocol.

3. Be between 18 and 39 (inclusive) years of age at the time of screening.

4. By self-report, habitually wear soft contact lenses in both eyes in a daily reusable or daily disposable wear modality (i.e., not extended wear modality). Habitual wear is defined as a minimum of 6 hours of wear per day, for a minimum of 2 days per week during the past four weeks.

5. Possess a wearable pair of spectacles that provide correction for distance vision.

6. In both eyes, have refractive error suitable for correction with the toric contact lens powers available in this study:

   1. Sphere powers (DS) -1.50 through -4.00 in 0.25 steps
   2. Cylinder powers (DC) -0.75 and -1.25
   3. Axes (°) 170, 180, 10, 80, 90, 100

7. Have best corrected monocular distance visual acuity of 20/30 or better in each eye.

Exclusion criteria

Potential subjects who meet any of the following criteria will be excluded from participating in the study.

The subject must not:

1. Be currently pregnant or lactating.
2. Be diabetic.
3. Be currently using any ocular medications or have any ocular infection of any type.
4. By self-report, have any ocular or systemic disease, allergies, infection, or use of medication that might contraindicate or interfere with contact lens wear, or otherwise compromise study endpoints, including infectious disease (e.g., hepatitis, tuberculosis), contagious immunosuppressive disease (e.g., Human Immunodeficiency Virus [HIV]), autoimmune disease (e.g., rheumatoid arthritis, Sjögren's syndrome), or history of serious mental illness or seizures. See section 9.1 for additional details regarding excluded systemic medications.
5. Have habitually worn rigid gas permeable (RGP) lenses, orthokeratology lenses, or hybrid lenses (e.g., SynergEyes, SoftPerm) within the past 6 months.
6. Be currently wearing monovision or multifocal contact lenses.
7. Be currently wearing lenses in an extended wear modality.
8. Have a history of strabismus or amblyopia.
9. Be an employee (e.g., Investigator, Coordinator, Technician) or immediate family member of an employee (including partner, child, parent, grandparent, grandchild or sibling of the employee or their spouse) of the clinical site.
10. Have participated in a contact lens or lens care product clinical trial within 7 days prior to study enrollment.
11. Have clinically significant (grade 3 or higher on the FDA grading scale) slit lamp findings (e.g., corneal edema, neovascularization or staining, tarsal abnormalities or bulbar injection) or other corneal or ocular disease or abnormalities that contraindicate contact lens wear or may otherwise compromise study endpoints (including entropion, ectropion, chalazia, recurrent styes, glaucoma, history of recurrent corneal erosions, aphakia, moderate or above corneal distortion, herpetic keratitis).
12. Have fluctuations in vision due to clinically significant dry eye or other ocular conditions.
13. Have had or have planned (within the study period) any ocular or intraocular surgery (e.g., radial keratotomy, PRK, LASIK, iridotomy, retinal laser photocoagulation, etc.).

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Crossover Assignment

Masking: Double Blind

---

67 participants in 2 patient groups

Test/Control

Experimental group

Description:

Eligible subjects who are habitual soft contact lens wearers will be randomized into the Test/Control sequence, to wear two different study lenses, one at a time, over two wear periods (test then control). Each wear period will be approximately 2 weeks in duration, with a washout period of approximately 1 week between wear periods. Subjects will be advised to wear the study lenses for a minimum of 8 hours per day on at least 5 days per week of each wear period.

Treatment:

Device: Delefilcon A contact lenses (CONTROL)

Device: Senofilcon A contact lenses (TEST)

Control/Test

Experimental group

Description:

Eligible subjects who are habitual soft contact lens wearers will be randomized into the Control/Test sequence, to wear two different study lenses, one at a time, over two wear periods (control then test). Each wear period will be approximately 2 weeks in duration, with a washout period of approximately 1 week between wear periods. Subjects will be advised to wear the study lenses for a minimum of 8 hours per day on at least 5 days per week of each wear period.
