Topical 2% Simvastatin for Xanthelasma Palpebrarum (STAT-LID)
A Randomized Clinical Trial of Topical 2% Simvastatin Versus Vehicle for Xanthelasma Palpebrarum
This study is evaluating whether a topical cream containing 2% simvastatin can improve xanthelasma palpebrarum, a common condition that causes yellow cholesterol deposits on the eyelids. Current treatments such as surgery, laser therapy, and chemical treatments can be effective but may cause scarring, pigment changes, or recurrence.
In this randomized, double-blind, vehicle-controlled trial, 30 adults with xanthelasma will be assigned to receive either topical 2% simvastatin cream or an identical inactive vehicle cream for 24 weeks. Neither participants nor investigators will know which treatment is being used during this period. After 24 weeks, all participants will receive active simvastatin treatment for an additional 24 weeks in an open-label extension.
The study will assess changes in lesion size and appearance using standardized photography and measurements, as well as patient satisfaction, quality of life, and treatment tolerability. Results from this pilot study will help determine whether topical simvastatin may be a safe and effective non-invasive treatment option for xanthelasma and inform the design of larger future studies.

干预/治疗 |
|---|---|
|
实验性的:Topical Simvastatin 2% Cream
Participants receive topical simvastatin 2% cream applied once nightly to xanthelasma lesions for 24 weeks during the double-blind phase.
Participants then continue active treatment during the 24-week open-label extension.
|
Topical simvastatin 2% formulated in a high-viscosity periocular-safe cream base.
Participants apply the cream once nightly to xanthelasma lesions for 24 weeks during the randomized double-blind phase.
One pump delivers approximately 0.25 mL, sufficient to cover the index lesion, with any remaining product applied to additional lesions.
Participants are instructed to avoid the lash line and conjunctiva.
Following completion of the blinded phase, all participants receive active treatment during a 24-week open-label extension.
|
|
安慰剂比较:Vehicle Cream
Participants receive an identical vehicle cream without active simvastatin applied once nightly for 24 weeks during the double-blind phase.
Following completion of the blinded phase, participants receive topical simvastatin 2% cream during the 24-week open-label extension.
|
Identical high-viscosity periocular-safe cream base without active simvastatin.
Applied once nightly to xanthelasma lesions during the 24-week randomized double-blind phase.
The vehicle is matched to active treatment in appearance, packaging, labelling, and application instructions to maintain study blinding.
Participants subsequently receive active topical simvastatin 2% cream during the open-label extension phase.
