Ocular Therapeutix™ Announces FDA Approval of Supplemental New Drug Application (sNDA) for DEXTENZA® (dexamethasone ophthalmic insert) 0.4 mg for Intracanalicular Use for the Treatment of Ocular Itching Associated with Allergic Conjunctivitis
Approval represents the first primarily office-based indication for DEXTENZA
“Allergic conjunctivitis is a common condition seen in the offices of eye care providers. We are really excited about this label expansion and the potential benefits for patients,” commented
“We appreciate the FDA’s hard work and ability to complete its review of our sNDA ahead of the scheduled
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. Data for the primary endpoint, ocular itching at Day 8, is shown below for all three studies (scale 0-4):

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%).

DEXTENZA is FDA approved for the treatment of ocular inflammation and pain following ophthalmic surgery and ocular itching associated with allergic conjunctivitis. DEXTENZA is a corticosteroid intracanalicular insert placed in the punctum, a natural opening in the inner portion of the lower eyelid, and into the canaliculus and is designed to deliver dexamethasone to the ocular surface for up to 30 days without preservatives. DEXTENZA resorbs and exits the nasolacrimal system without the need for removal.
IMPORTANT SAFETY INFORMATION
DEXTENZA is contraindicated in patients with active corneal, conjunctival or canalicular infections, including epithelial herpes simplex keratitis (dendritic keratitis), vaccinia, varicella; mycobacterial infections; fungal diseases of the eye, and dacryocystitis.
WARNINGS AND PRECAUTIONS
Intraocular Pressure Increase
Prolonged use of corticosteroids may result in glaucoma with damage to the optic nerve, defects in visual acuity and fields of vision. Steroids should be used with caution in the presence of glaucoma. Intraocular pressure should be monitored during treatment.
Corticosteroids may suppress the host response and thus increase the hazard for secondary ocular infections. In acute purulent conditions, steroids may mask infection and enhance existing infection.
Use of ocular steroids may prolong the course and may exacerbate the severity of many viral infections of the eye (including herpes simplex).
Fungus invasion must be considered in any persistent corneal ulceration where a steroid has been used or is in use. Fungal culture should be taken when appropriate.
Use of steroids after cataract surgery may delay healing and increase the incidence of bleb formation.
The most common ocular adverse reactions that occurred in patients treated with DEXTENZA were: anterior chamber inflammation including iritis and iridocyclitis (10%); intraocular pressure increased (6%); visual acuity reduced (2%); cystoid macular edema (1%); corneal edema (1%); eye pain (1%) and conjunctival hyperemia (1%).
The most common ocular adverse reactions that occurred in patients treated with DEXTENZA were: intraocular pressure increased (3%); lacrimation increased (1%); eye discharge (1%) and visual acuity reduced (1%).
The most common non-ocular adverse reaction that occurred in patients treated with DEXTENZA, for ophthalmic surgery and allergic conjunctivitis, was headache (1%).
