Rare dermatological conditions like Xeroderma pigmentosum (XP) are autosomal recessive syndromes resulting from specific congenital defects in the nucleotide excision repair pathway. There is no known cure for these disorders, which are life-threatening and cause a significant impact in the life of these patients. Despite presenting variable symptoms, common skin manifestations can be identified, such as heightened sun sensitivity, freckling in sun-exposed areas of the skin and dryness.
The management of these clinical conditions is contingent upon their severity, with the primary focus on early diagnosis, lifelong protection from UV light, and symptom-based supportive treatments. In accordance with current medical guidelines, patients are advised to apply sunscreens with high SPF daily to minimize UV exposure.
In the case of XP, a pronounced increase in the incidence of skin cancer has been reported and the patients undergo frequent surgical resection of skin lesions. The current chalenges of the management of these skin conditions are mainly related to safety concerns regarding daily exposure to titanium dioxide nanoparticles used as photoprotective agents in sunscreens, as wel as regarding the topical application of anticancer drugs.
The NANO4RARESKIN project aims to upgrade the management of rare skin conditions related to DNA repair disorders by designing daily maintenance, multifunctional and nanotechnology-based formulations with photoprotective, antioxidant, and skin barrier recovery properties.
The strategy for innovation wi l be based on the optimization of lipid-based nanosystems containing ceramides and phyto-antioxidants and further combined with titanium dioxide nanoparticles using a Quality-by-Design approach. These nanosystems wi l be characterized and incorporated in semisolid formulations, finaly proceeding to stability, safety, and efficacy assessments.
Upon completion of the NANO4RARESKIN project, it is expected that at least one nanotechnology-based formulation wi l be poised for knowledge transfer and contribute towards a safer and cost-effective daily management of XP. The accomplishment of the NANO4RARESKIN objectives wi l be ensured by the know-how on lipid-based nanosystems for skin drug delivery, supported by a multidisciplinary team of CBIOS researchers. This befitting group wi l also be dedicated to dissemination/communication activities, so that the major project breakthroughs may have societal impact.
