Abstract

Purpose : We desired to develop a new topical ocular anesthetic with good bioavailability in anterior segment tissues. As well, given concerns about contamination and sterility in multi-dose products, we selected a unit-dose, non-preserved presentation in blow-fill-seal containers (similar to currently marketed pharmacological therapies for dry eye disease). The primary objective of these two Phase 3, randomized, placebo-controlled, double-masked, parallel design studies in healthy subjects was to evaluate anesthetic efficacy of AG-920. The secondary objectives included and the safety and tolerability of AG-920.

Methods : In each study, 120 subjects were randomized to receive a single dose of AG-920 or identical looking placebo into one (study) eye (2 drops 30 seconds apart). Subjects underwent a conjunctival pinch procedure and the pain associated with the pinch assessed. A priori, the primary endpoint was “no pain at 5 minutes”.

Results : AG-920 provide a rapid onset of local anesthesia (less than one minute) with clinically and statistically significantly greater effect in AG-920 (68% and 83%) than placebo (3% and 18%, for Study 1 and Study 2, respectively, p < 0.0001). The most frequently adverse event was instillation site pain (27% vs 3%), followed by conjunctival hyperemia (probably related to the pinch, 9% vs 10%) in the AG-920 and placebo groups, respectively.

Conclusions : A single dose of AG-920 (two drops 30 seconds apart) resulted in local ocular anesthesia in a short period of less than half minute and lasting up to approximately 15 minutes or longer. Other than mild conjunctival hyperemia, there were no clinically significant safety findings.
