“My eyes had felt irritated for a while. When it started to get really bad, I decided I had to talk to an eye doctor. After trying an artificial tear, I got temporary relief, but I needed more. I’m glad after just a few weeks I was prescribed Xiidra®.”

- Ar’Tee

Patient history

  • Symptoms of eye irritation, pain, itchiness, and feeling of debris in the eye since the summer of 2020
  • Has 20/20 vision without corrective lenses

“It literally felt like sandpaper grinding on my eyeballs. That was super uncomfortable, I don’t wish that feeling on anybody.”

- Ar’Tee


Clinical presentation

  • Initial visit to Dr. Davison in July 2020; experienced mild infrequent symptoms that gradually progressed over time
  • Symptoms: Eye pain, itch, and irritation
  • Treatment history: Artificial tear use (provided temporary relief) and topical antibiotic for suspected infection

Clinical trial data

  • Xiidra reduced symptoms of eye dryness at 2 weeks in 2 out of 4 studies, with improvement observed at 6 and 12 weeks in all 4 studies1
  • Notable improvements in signs of dry eye disease: In 3 out of 4 studies, a larger reduction in Inferior fluorescein Corneal Staining Score (ICSS) favoring Xiidra was observed at 12 weeks1

Relevant Xiidra clinical trial information

Xiidra is indicated for the treatment of signs and symptoms of dry eye disease (DED).

The safety and efficacy of Xiidra were assessed in four 12-week, randomized, multicenter, double-masked, vehicle-controlled studies (N=2133). Patients were dosed twice daily. The mean age was 59 years (range, 19-97 years). The majority of patients were female (76%). Use of artificial tears was not allowed during the studies. The study end points included assessment of signs (based on Inferior fluorescein Corneal Staining Score [ICSS] on a scale of 0 to 4) and symptoms (based on patient-reported EDS on a visual analogue scale of 0 to 100). Effects on symptoms of dry eye disease: a larger reduction in EDS favoring Xiidra was observed in all studies at day 42 and day 84. Xiidra reduced symptoms of eye dryness at 2 weeks (based on EDS) compared to vehicle in 2 out of 4 clinical trials. Effects on signs of dry eye disease: at day 84, a larger reduction in ICSS favoring Xiidra was observed in 3 out of the 4 studies.1

Lissamine green

Lissamine green staining was graded using a 5-point scale (0=none, 4=severe; 0.5 point increments) by region (temporal and nasal). Staining scores below represent the total conjunctival region.2

  • Phase II: Mean lissamine green staining scores at baseline were 3.12, with a mean change from baseline to day 84 of 0.13 in the 5.0% lifitegrast group vs a mean score of 3.31 at baseline, with a mean change from baseline to day 84 of 0.11 in the placebo group.3
  • OPUS-1: Mean lissamine green staining scores at baseline were 7.09, with a mean change from baseline to day 84 of -0.72 in the 5.0% lifitegrast group vs a mean score of 6.94 at baseline, with a mean change from baseline to day 84 of -0.30 in the placebo group. Change from baseline to day 84 was calculated using a pre-CAE baseline value.4
  • OPUS-2: Mean lissamine green staining scores at baseline were 4.02, with a mean change from baseline to day 84 of -0.54 in the lifitegrast group vs a mean score of 4.03 at baseline, with a mean change from baseline to day 84 of -0.55 in the placebo group.5
  • OPUS-3: Mean lissamine green staining scores at baseline were 2.09, with a mean change from baseline to day 84 of -0.34 in the lifitegrast group vs a mean score of 2.14 at baseline, with a mean change from baseline to day 84 of -0.24 in the placebo group.2

OSDI

OSDI (ocular surface disease index) was a 12-question, subject-related, dry eye disease index (0-100 scale; 0=normal, 100=severe). OSDI scores are not available for OPUS-3. OSDI scores below represent the total OSDI score.3

  • Phase II: Mean OSDI scores at baseline were 31.77, with a mean change from baseline to day 84 of -4.65 in the 5.0% lifitegrast group vs a mean score of 28.84 at baseline, with a mean change from baseline to day 84 of -0.09 in the placebo group.3
  • OPUS-1: Mean OSDI scores at baseline were 26.03, with a mean change from baseline to day 84 of -2.98 in the lifitegrast group vs a mean score of 27.05 at baseline, with a mean change from baseline to day 84 of -3.84 in the placebo group.4
  • OPUS-2: Mean OSDI scores at baseline were 40.78, with a mean change from baseline to day 84 of -13.77 in the lifitegrast group vs a mean score of 39.83 at baseline, with a mean change from baseline to day 84 of -7.69 in the placebo group.5

Lissamine green staining scores were analyzed as a secondary efficacy endpoint in Phase II and OPUS-2, as a tertiary efficacy endpoint in OPUS-1, and as an assessment related to safety in OPUS-3. OSDI scores were analyzed as a secondary efficacy endpoint in Phase II and OPUS-1, and as a tertiary efficacy endpoint in OPUS-2.2-5

Phase II and OPUS-1 were CAE (controlled adverse environment) studies. The controlled adverse environment procedure was used to enrich the study population at screening by identifying subjects with the ability to exacerbate both signs (inferior cornea staining) and symptoms (ocular discomfort score) following 90 minutes of exposure. In Phase II study, a total of 5 challenges with the CAE were scheduled during screening and treatment (1 CAE at each visit). Ocular assessments and subject self-assessments were conducted prior to, during, and following each CAE in both eyes. In OPUS-1, a total of 2 screening challenges with the CAE were scheduled during the Screening Period; the CAE was not used to assess subjects during the Treatment Period.3,4,6


Diagnostic evaluation of Ar'Tee

  • Dry eye disease associated with meibomian gland dysfunction findings
  • Lissamine green staining of 2-3+ and NaFl staining revealing evidence of dry eye disease
  • Meibography7:
    • Lower lids OU showed 25%-50% meibomian gland loss
    • Upper lids showed 0%-25% meibomian gland loss
  • No corneal staining was performed at this point

“I wasn’t comfortable looking at a computer screen all day while I was working from home.”

“Sometimes it was hard to drive at night.”

“My eyes were bothering me a lot and making it difficult for me sometimes.”

Ar’Tee’s eye care provider and her plan

Janelle Davison, OD/Optometrist

Dr. Davison is a paid consultant for Novartis.

“When I first saw Ar’Tee, he reported pain and itch in his eyes. It’s likely that Ar’Tee had some signs and symptoms preceding the event that caused him to go to his primary care physician. After running the lissamine green staining test and seeing his OSDI scores, it was clear that he had dry eye disease and would be a good candidate for prescription Xiidra®.”7

- Dr. Davison


Initial treatment plan

  • 90-day Rx for twice-daily Xiidra1
  • Eyelid wipes9
  • Apply warm compresses9
  • Omega-3 fish oils9
  • In-office device therapy9
red quote icon

“Ar’Tee responded incredibly well to treatment with Xiidra after 2 weeks. His response was very good to see in that short period of time.”

- Dr. Davison


Patient counseling included:

  • Administration: Patient was advised to apply the Xiidra drops twice per day, one in each eye, 12 hours apart1
  • Safety profile: Dr. Davison reminded Ar’Tee that there are some potential side effects, such as blurred vision and burning1,10

"I am always certain to demonstrate to the patient that this is not going to be a quick fix. For Ar’Tee, Xiidra was part of a long-term management plan for dry eye disease as we worked to alleviate his painful symptoms."
