DRY EYE
Corneal fluorescein staining score, the primary efficacy endpoint, decreased by 6.8 ± 4.0, 5.7 ± 3.9, and 4.6 ± 3.6 points in the 3 groups respectively, indicating superior efficacy in test arm A in comparison to control arm C (p = 0.0026). Schirmer’s tear test, conjunctival lissamine staining score, ocular surface disease index, and individual dry eye symptom scores also favoured higher dose MNP cyclosporine over Restasis™. The study failed to differentiate the treatment arms in terms of clinician’s global evaluation of treatment, use of tear substitutes, best corrected visual acuity or safety and toleration.
