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 (approximately 12 hours apart). Use of artificial tears was not allowed during the studies. The study end points included assessment of signs (based on ICSS on a scale of 0–4) and symptoms (based on patient-reported Eye Dryness Score on a visual analogue scale of 0–100).1
Based on analysis of covariance (ANCOVA) model adjusted for baseline value in Study 1, and ANCOVA model adjusted for baseline value and randomization stratification factors in Studies 2–4. All randomized and treated patients were included in the analysis and missing data were imputed using last-available data. In Study 1, one Xiidra-treated patient who did not have a baseline value was excluded from analysis. In Study 2, one vehicle-treated patient who did not have a study eye designated was excluded from analysis.1

BL, baseline; CLDEQ-8, contact lens dry eye questionnaire-8; VAS, visual analog scale.
‡The CLDEQ-8 was administered at every visit. Participants circled the answer to each of the 8 questions that best corresponded to their experience
with their habitual contact lenses for the past 2 weeks. Once completed, the answers were summed up to form an overall score (possible range 1–37).8
§Indicates significant difference vs baseline.
ǁDry eye symptoms were rated by patients using a VAS 0–100, with 100 being worst.
¶The range of VAS scores for EOD symptoms were as follows: burning/stinging at baseline (0–91), 2 weeks (0–73), 6 weeks (0–75), 12 weeks (0–62);
foreign body sensation at baseline (0–94), 2 weeks (0–98), 6 weeks (0–82), 12 weeks (0–96); photophobia at baseline (0–77), 2 weeks (0–79), 6 weeks
(0–77), 12 weeks (0–45); and ocular pain at baseline (0–85), 2 weeks (0–61), 6 weeks (0–49), 12 weeks (0–23).8
While mean total wear time remained the same over time, patients taking Xiidra achieved significantly longer comfortable wear time vs baseline at all follow-up visits (baseline: 6.5 hours, 12 weeks: 9.1 hours; P<0.01)8
Study Design
A single-center, prospective, open-label study of 40 patients who wear contact lenses and experience symptoms of eye dryness and contact lens discomfort evaluated whether symptomatic contact lens wearers achieve improvements in comfort and dryness when treated with Xiidra for 12 weeks. Patients attended a baseline and dispense visit and 3 follow-up visits after 2, 6, and 12 weeks. Study variables collected at all visits included EOD dryness and EOD discomfort ratings (0–100 VAS; 100=worst), CLDEQ-8 score and total and comfortable contact lens wear time. Xiidra was administered as 1 drop, twice daily (approximately 12 hours apart) into each eye, and contact lenses were removed prior to administration and reinserted 15 minutes following administration per the label. Participants included patients ≥18 years of age who were symptomatic habitual soft contact lens wearers who had a history of artificial tear (AT) or rewetting drop use at least once in the last 30 days and who were willing to use Xiidra twice daily (irrespective of contact lens wear) and to stop use of any habitual rewetting drops and/or ATs over the 12-week study.7,8
Study Limitations
A single-center, open-label study design with no control treatment arm. All participants had to have used ATs or rewetting drops at least once in the month prior to study start; only 30% of participants had used these eye drops twice per day (Xiidra dosing frequency), while the remaining 70% either had to increase (62%) or decrease (8%) their daily dosing frequency during the study. It is possible that the more frequent use of Xiidra as compared to previous drops could have contributed to the reduction in symptoms in some participants.8 Data should be interpreted with the study design and these limitations in mind. No formal conclusions should be drawn.

SPEED, Standardized Patient Evaluation of Eye Dryness.
*Data extracted from secondary outcomes. Results were consistent with pivotal trials.11
†Dry eye symptoms were measured by SPEED scores. SPEED scores >10 are considered highly symptomatic of dry eye disease.11
‡The mean overall SPEED scores at baseline: 8.1 ± 6.6; after the initial 28 days of Xiidra: 6.3 ± 4.9; and after surgery continued Xiidra
treatment: 4.0 ± 3.2 (P<0.0004, paired t-test).11

¶After 28-day treatment with Xiidra, 52 (63%) patients had no staining, 29 (35%) had grade 1, and 2 (2%) had grade 2 or greater staining.11

Study Design
A multicenter, prospective, open-label study of 100 eyes of 100 patients who were diagnosed with dry eye disease before cataract surgery. Biometry measurements were taken before surgery prior to treatment with Xiidra and again after a 28-day treatment regimen with Xiidra twice daily. The primary outcome was an improvement in the accuracy of preoperative anterior corneal power measurements at predicting postoperative spherical equivalent before and after Xiidra treatment. Secondary outcomes included changes in dry eye symptoms, as measured by SPEED scores, and dry eye signs such as corneal staining.11
Study LimitationsStudy Limitations
There was an unexplained noncompliance rate with the first course of lifitegrast of almost 20%. While reasons for discontinuation were not collected formally, anecdotal reports from patients suggested that discomfort with drop instillation was the main reason for discontinuation. Additionally, some patients did not return for their 1-month postoperative follow-up exam; however, 58 patients were enough to generate a statistical significance threshold. Some patients did not receive a second round of treatment with lifitegrast after surgery, and data were not captured on the cause for declining a second course. However, nearly the first third of study participants completed the study before the additional month of lifitegrast (postoperatively) was added to the protocol.11
Data should be interpreted with the study design and these limitations in mind. No formal conclusions should be drawn.
