About LNZ100 (aceclidine) and LNZ101 (aceclidine + brimonidine)

Aceclidine is a small molecule acetylcholine receptor agonist that causes pupil contraction, or miosis, creating a pinhole effect that improves near vision. Studies have shown that aceclidine�s mechanism of action (MOA) is ideally positioned to create a pinhole pupil effect while avoiding myopic shift. It is crucial to minimize myopic shift as it can significantly impair distance vision for a majority of presbyopes.

Aceclidine�s unique MOA, in which miosis is decoupled from myopic shift, is expected to allow it to target the broadest patient population.

In clinical trials, LENZ has shown that near-vision improvement correlates to aceclidine�s ability to maintain a pinhole pupil sweet spot of 1.5 mm to 2 mm for at least seven hours. There was no loss and a slight trend toward net gain in best corrected distance vision. In addition, aceclidine was well tolerated with no serious adverse events and with mild discomfort on instillation as the most common side effect.

LENZ�s INSIGHT clinical trial will serve as a confirmatory lead-in for its Phase 3 trial that is planned for 2H 2022.
