How it works

How XDEMVY works

Lotilaner is a gamma-aminobutyric acid (GABA)-gated chloride channel inhibitor selective for mites. Inhibiting these channels paralyzes the mite, leading to its death. Lotilaner is not an inhibitor of mammalian GABA-mediated chloride channels at up to 30 µM in vitro.

Selective for mites

Lotilaner acts on mite GABA-gated chloride channels to target, paralyze and kill Demodex mites.

Collarette reduction

In Saturn-1 and Saturn-2, 44% and 55% of XDEMVY patients reached 2 or fewer collarettes per upper lid at Day 43, versus 7% and 12% with vehicle (p<0.01).

Mite eradication

Mite eradication at Day 43 was 68% and 50% with XDEMVY, versus 17% and 14% with vehicle (p<0.01).

Erythema cure

Erythema cure at Day 43 was 19% and 30% with XDEMVY, versus 7% and 9% with vehicle (p<0.01).

Comfortable drop

An average of about 90% of patients in both groups rated the drop neutral to very comfortable.
