Effect of OTX-101 0.09% ciclosporin solution on clinical signs of dry eye disease in patients with moderate-to-severe corneal damage: a post-hoc analysis of randomized clinical trials

Resumo original em inglês

O que aconteceu

This post-hoc analysis of two OTX-101 clinical trials assessed the efficacy of 0.09% ciclosporin in treating dry eye disease (DED) patients with moderate-to-severe corneal damage.

The criteria for moderate-to-severe corneal damage were defined as a CFS total score (5 zones) of ≥ 6 or single zone ≥ 2 at baseline (modified NEI scale). 516 patients (49% of the intention-to-treat population) met these criteria at baseline. Changes in ocular surface damage (cornea and conjunctiva) and aqueous tear deficiency from baseline were determined through corneal fluorescein staining (CSF), Lissamine green staining (LGS) and Schirmer's test without anesthesia (ST).

O que encontraram

After 12 weeks of treatment with OTX-101 versus (vs.) vehicle, outcomes improved across six parameters: (I) Central CFS mean change from baseline was -0.48 vs. -0.36, p = 0.0144. (II) Total CFS corneal staining change from baseline was -2.30 vs. -1.61 p = 0.0004. (III) Improvement ≥ 50% in total CFS from baseline was 44.8% vs. 33.4% p = 0. 0010. (IV) Conjunctival damage as measured by LGS mean change from baseline was -1.61 vs. -0.99, p = 0.0006. (V) Tear production as measured by ST as percentage of eyes with ≥ 10 mm increase from baseline was 18.2% vs. 8.3% p = 0.0003, and (VI) ST mean change from baseline was +2.94 vs. +0.28 p = 0.0008.

Por que isso importa

Administration of OTX-101 0.09% leads to statistically significant improvement across six parameters in ocular surface staining and tear production in DED patients with moderate to severe corneal damage.
