The randomised, double-masked, vehicle-controlled, two-way crossover design allergen chamber Phase 3 INVIGORATE Trial enrolled 95 allergic conjunctivitis patients.

The primary efficacy endpoint was a change from baseline in subject-reported ocular itching score on a 0‑4 point scale over a majority of 11 time points from 110 to 210 minutes after allergen chamber entry. The key secondary endpoint was a change from baseline in ocular redness on a 0‑4 point scale throughout the allergen chamber (approximately 3.5 hours).

Aldeyra now plans to meet with the US Food and Drug Administration (FDA) in the second half of 2021 to discuss the results and the potential submission of a New Drug Application.

“The statistically significant superiority of reproxalap over vehicle across all allergic conjunctivitis symptoms and signs assessed in INVIGORATE is remarkable, and suggests utility in one of the world’s most common ocular surface diseases,” stated Todd Brady, President and CEO of Aldeyra.
