What this trial studies

This observational trial investigates the effectiveness of hydroxychloroquine (HCQ) versus methotrexate (MTX) in treating adults diagnosed with lichen planopilaris (LPP), a form of cicatricial alopecia that leads to irreversible hair loss. Patients will choose their preferred treatment option and receive follow-up care according to standard clinical practices over a duration of up to 48 weeks. The study aims to address the lack of established treatment guidelines for LPP by providing insights into the effectiveness of these commonly used systemic therapies in routine clinical care.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 years and older who have been diagnosed with lichen planopilaris and are willing to provide informed consent.

Not a fit: Patients with a different histopathological diagnosis than LPP or those unable to adhere to the study protocol may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable evidence to guide treatment decisions for patients with lichen planopilaris, potentially improving their quality of life.

How similar studies have performed: While there is limited evidence from randomized controlled trials, this study aims to fill a significant gap in knowledge regarding the effectiveness of systemic treatments for cicatricial alopecia, making it a novel approach.
