Sun Pharmaceutical has shared new Phase 4 clinical trial data, showcasing the efficacy of Cequa (cyclosporine ophthalmic solution) 0.09% in treating dry eye disease (DED). The results reveal that Cequa provides sustained improvements in patients whose symptoms were inadequately managed with Restasis (cyclosporine ophthalmic emulsion) 0.05%.
The multicenter, open-label, single-arm study enrolled 134 adult DED patients who had used Restasis for at least three months without sufficient relief. Over a 12-week period, researchers assessed improvements in corneal health and visual acuity, along with other key patient outcomes.
• Corneal Health: Significant reductions in total corneal fluorescein staining (CFS) were observed as early as Week 4, with continued improvement through Week 12.
• Visual Acuity: Patients experienced marked enhancements in best corrected visual acuity (BCVA), starting at Week 8 and further improving by Week 12.
• Patient-Reported Outcomes: Participants reported notable improvements in corneal staining and dry eye symptoms as measured by the modified symptom assessment in dry eye (mSANDE).
Cequa utilizes Sun Pharma’s proprietary nanomicellar NCELL technology, which enhances the bioavailability and penetration of cyclosporine. This makes it the first and only FDA-approved cyclosporine therapy to use this advanced delivery system, offering improved efficacy and patient outcomes.
The study demonstrated a safety profile consistent with existing cyclosporine treatments:
• Adverse Events (AEs): Mild treatment-emergent AEs were reported by 62.7% of participants, most commonly instillation site discomfort.
• Serious AEs: Rare, affecting fewer than 2% of participants.
• Low Discontinuation Rates: Only 14.2% of participants discontinued treatment for any reason during the study.
These Phase 4 results highlight Cequa’s potential as an effective alternative for patients with DED who do not respond adequately to other cyclosporine treatments. By improving corneal health, visual acuity, and patient-reported outcomes, Cequa is poised to play a critical role in advancing the management of dry eye disease.
