Clinical and experimental aspects of tirbanibulin treatments.

Tirbanibulin is a topical medication approved in 2020 as a 5 day topical treatment for actinic keratosis, a precancerous skin lesion characterized by the hyperproliferation of atypical keratinocytes. Tirbanibulin exerts its effects through dual mechanisms: microtubule inhibition, which disrupts cell division, and Src kinase inhibition, which interferes with cancer-associated signaling pathways. Although its primary use is in AK, these mechanisms suggested potential therapeutic applications in a broader range of epithelial cancers. In this literature review, we explored tirbanibulin's application in not only actinic keratosis, but also in squamous cell carcinoma and basal cell carcinoma. We addressed the relevant findings obtained in recent papers to evaluate tirbanibulin's safety, efficacy, side effects, real-life clinical experiences, and its potential in anti-aging and skin lightening therapies on patients. In summary, we highlighted the preclinical and clinical evidence on the use of tirbanibulin as an effective and safe treatment option beyond AK. Graphical Abstract.
