  6. Slide 6: Aldehyde Traps: A Novel Therapeutic Approach

    Aldeyra’s lead aldehyde trap, NS2, appears to have minimal pharmacology, with no known effects on receptors, enzymes and other proteins. In clinical trials to date, NS2 has been observed to be safe and well-tolerated. Aldeyra is not aware of any similar technology. Aldeyra’s lead aldehyde trap, NS2,
