FDA approval for sBLA for Dextenza for intracanalicular use for treatment of ocular itching associated with conjunctivitis.
With the approval, Dextenza is the first, FDA-approved, physician-administered intracanalicular insert capable of delivering a preservative-free drug for the treatment of ocular itching associated with allergic conjunctivitis with a single administration for up to 30 days.
Dextenza originally received FDA approval in November 2018 for the treatment of ocular pain following ophthalmic surgery, followed by an expansion of the label to also include the treatment of ocular inflammation following ophthalmic surgery in June 2019.
The efficacy of Dextenza for the treatment of ocular itching associated with allergic conjunctivitis was based on three randomized, multicenter, double-masked, parallel group, vehicle-controlled studies in subjects with a positive history of ocular allergies and positive skin test reaction to perennial and seasonal allergens (n=255). In all three trials, Dextenza demonstrated lower mean ocular itching scores compared with the vehicle group at all time points throughout the study duration of up to 30 days. In two of the three studies, a higher proportion of patients had statistically significant reductions in ocular itching on Day 8, at 3 minutes, 5 minutes and 7 minutes post-challenge in the Dextenza group compared to the vehicle group.
Dextenza was observed to have a favorable safety profile and be generally well-tolerated in the allergic conjunctivitis as well as the ocular inflammation and pain clinical populations. The most common ocular adverse events seen in the pooled analysis of the allergic conjunctivitis studies were: increased intraocular pressure (3%), increased lacrimation (1%), eye discharge (1%) and reduced visual acuity (1%). The most common non-ocular adverse reaction that occurred in patients treated with Dextenza for allergic conjunctivitis was headache (1%).
