To evaluate and compare the efficacy of a lipid-based lubricant eyedrop formulation (hydroxypropyl guar/propylene glycol/phospholipid [HPG/PG/PL]) with preservative-free saline for the treatment of dry eye.
This was a prospective, multicenter, randomized, single-masked, parallel-group phase 4 clinical study. Patients ≥18 years diagnosed with dry eye received 1 drop of saline 4 times daily (QID) for 15 days during a run-in phase, followed by randomization. Patients then instilled HPG/PG/PL or saline QID through day 35 and as needed through day 90. Change in tear film break-up time (TFBUT), change in total ocular surface staining (TOSS) score, and Impact of Dry Eye on Everyday Life (IDEEL) were evaluated on day 35.
Increase in TFBUT from baseline to day 35 was assessed during the interim and final analyses. Mean ± SE difference between the HPG/PG/PL (n = 110) and saline groups (n = 100) was 1.3 ± 0.4 seconds (interim analysis; 95% confidence interval [CI] 0.5-2.1 seconds; p = 0.0012) and 1.0 ± 0.3 seconds (final analysis; 95% CI 0.4-1.6 seconds; p = 0.0011), demonstrating the superiority of HPG/PG/PL. The mean ± SE difference between the HPG/PG/PL and saline groups for IDEEL treatment effectiveness scores was 16.0 ± 3.6 (95% CI 8.9-23.1; p<0.0001). No significant differences in TOSS scores or IDEEL inconvenience scores were observed between treatment groups.
Thirty-five days of QID HPG/PG/PL treatment resulted in a statistically significant improvement in TFBUT and IDEEL treatment effectiveness scores compared with saline but not in TOSS or IDEEL treatment inconvenience scores. HPG/PG/PL was well-tolerated by patients.
