Sun Pharma Cequa Phase 4 data shows sustained improvement in Dry Eye Disease signs, symptoms in patients switched from Restasis
Mumbai: Sun Pharmaceutical Industries Limited has announced the presentation of Phase 4 data showing that CEQUA (cyclosporine ophthalmic solution) 0.09% induces sustained improvement in the signs and symptoms of dry eye disease (DED).
CEQUA ophthalmic solution is a calcineurin inhibitor immunosuppressant indicated to increase tear production in patients with keratoconjunctivitis sicca (dry eye).
In a presentation at the American Academy of Optometry (AAOPT) 2023 annual meeting in New Orleans, La., researchers reported that CEQUA elicited significant improvement in corneal fluorescein staining (CFS, a test used to detect damage to the cornea) and in modified Symptom Assessment in Dry Eye (mSANDE) scores in patients with DED whose disease was uncontrolled on Restasis (cyclosporine ophthalmic emulsion) 0.05% therapy.
In the 12-week Phase 4 multicenter study, twice-daily administration of CEQUA improved CFS and mSANDE scores starting at Week 4 of treatment and maintained these improvements through Week 12.
"CEQUA offers a high concentration of cyclosporine for ophthalmic use and is the first and only U.S. Food and Drug Administration (FDA)-approved cyclosporine treatment delivered with nanomicellar NCELL technology, which helps to improve the bioavailability of cyclosporine, resulting in improved ocular tissue penetration," the Company stated.
“We were greatly encouraged to observe significant improvements in dry eye signs and symptoms as early as four weeks into treatment with CEQUA, and to see even greater improvements at eight weeks and again at 12 weeks,” said lead investigator Josh Johnston, OD, FAAO, of Georgia Eye Partners in Atlanta, Ga. “Moreover, by assessing corneal fluorescein staining in all five zones of the cornea, we were able to attain a more complete characterization of corneal health than in many dry eye disease trials, which typically assess only a few corneal areas.”
The study enrolled adults with DED inadequately controlled (i.e., still symptomatic and/or exhibiting disease signs) on current Restasis therapy for at least three months, and who had a history and clinical diagnosis of DED for at least three months before screening/baseline. Patients received one drop of CEQUA in each eye twice daily for 12 weeks. Investigators assessed CFS and mSANDE scores at baseline and at Weeks 4, 8, and 12, and/or upon early discontinuation from the study. CFS was scored on a 0-4 grading scale in 0.5-point increments, with a score of 0 indicating no stain (i.e., healthy cornea) and a score of 4 reflecting a severe stain; investigators calculated a total CFS score by summing all five corneal area scores. The mSANDE questionnaire ssessed frequency and severity of DED symptoms of dryness and irritation on a 0-100 scale, with 0 representing very low frequency/severity and 100 indicating very high frequency/severity.
