Ocular Therapeutix™ Announces Topline Results for Phase 2 Clinical Trial of OTX-CSI for the Treatment of Dry Eye Disease Did Not Meet Primary Endpoint
The Phase 2,
The study did not show separation between the OTX-CSI treated subjects (both formulations) and the vehicle treated subjects (both formulations) for the primary endpoint of increased tear production at 12 weeks as measured by the Schirmer’s Test. Change from baseline (improvement) in mean Schirmer’s Test scores for the four groups were as follows: OTX-CSI F1: 1.98 mm, OTX-CSI F2a: 1.91 mm, Vehicle F2b: 2.24 mm and Vehicle F3: 3.08 mm.
The study did show an improvement compared with baseline in signs of dry eye disease as measured by total corneal fluorescein staining (CFS) and symptoms of dry eye disease as measured by the visual analogue scale (VAS) eye dryness in subjects treated with the OTX-CSI insert (both formulations) starting as early as two weeks after insertion and continuing over the 12 weeks study period. These improvements were not statistically significant compared with vehicle insert (both formulations) for either CFS or VAS eye dryness (severity and frequency) at 12 weeks.
Overall, the OTX-CSI insert (both formulations) was generally observed to have a favorable safety profile and was well tolerated. There were no ocular serious adverse events. No subjects dropped out of the trial due to an adverse event. The most common ocular adverse event was ocular pruritis which was seen in less than 16% of subjects. The adverse events of ocular discomfort or pain were seen in less than 3% of subjects. The most common non-ocular event was COVID-19 and was seen in 3% of subjects.
“We would like to thank the patients and investigators who participated in the OTX-CSI clinical trial,” said
About Dry Eye Disease
Dry eye disease is a common, multifactorial disease of the tears and ocular surface that results in symptoms of discomfort (such as burning sensation, itching, redness, stinging, pain and foreign body sensation), visual disturbance, and tear film instability that can cause potential damage to the ocular surface. Inflammation of the lacrimal gland and ocular surface have been shown to play a key role in dry eye disease, resulting in a reduction in tear production. Dry eye disease is one of the most common ophthalmic disorders presenting to clinicians and the Market Scope 2019 Dry Eye Products Market Report estimated that more than 17.2 million adults in
