Clinical trials

The Multimodal Laser Project is a prospective, randomized, split-face clinical study investigating a novel combination of laser and light-based treatments for facial photodamage with the long-term perspective of improving skin cancer prevention. The study includes 35 patients with facial photodamage and AKs. One side of the face receives a multimodal treatment combining three complementary technologies: 1927-nm thulium laser, 1550-nm non-ablative fractional laser, and intense pulsed light (IPL), while the contralateral side serves as an untreated control. Participants are followed for 14 months to assess both clinical efficacy and longer-term preventive effects. The overall aim is not only to determine whether multimodal laser treatment improves photodamaged skin, but also to gain a deeper understanding of how the treatment affects the underlying biology of chronically sun-damaged skin and its potential role in skin cancer prevention.

Solid organ transplant recipients (OTRs) receive lifelong immunosuppressive therapy, which puts them at increased risk of cutaneous and mucosal cancers. In particular, OTRs have increased risk of skin cancer and cancers caused by human papillomavirus (HPV), including cervical cancer and oropharyngeal cancer. There is currently limited knowledge on risk factors for HPV infection and skin cancer in OTRs, and limited knowledge on the natural history of HPV infection and cervical neoplasia in OTRs compared with immunocompetent controls. With a continuously increasing number of OTRs, there is a growing need to improve our understanding of the long-term reactions to immunosuppression. The overall aim of this study is to investigate long term effects of immunosuppression on cutaneous and mucosal epithelium in Danish OTRs, including the risk of skin dysplasia and skin cancer, cervical and oral HPV infection and HPV-related dysplasia and cancer in OTRs. This study will be designed as a prospective observational cohort study based on clinical data and data from nationwide Danish registries. A total of 600 female OTRs, 300 male OTRs and 600 female controls will be included from Danish dermatology departments. The study aims to provide knowledge relevant for improving prevention of skin- and HPV-related cancers in OTRs, including personalized screening recommendations according to individual patient risk.
