E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To investigate the efficacy of photodynamic therapy for treating Lentigo maligna using 5-aminolevulinic acid nanoemulsion as a light sensitizing cream. Patients receive photodynamic treatment three times consecutively with intervals of two weeks. Four weeks after last photodynamic treatment the Lentigo maligna will be removed surgically from the skin. Result of the treatment is assessed with histopatological examination and immunohistochemical staining of removed tissue specimen. |
Selvittää, onko fotodynaaminen hoito tehokas Lentigo malignan hoitomuoto käyttäen valoherkistäjän 5-aminolevulinaatti-nanoemulsiota. Potilaat saavat fotodynaamista hoitoa yhteensä kolme kertaa kahden viikon välein. Neljän viikon kuluttua viimeisestä fotodynaamisesta hoidosta Lentigo maligna leikataan iholta kirurgisesti. Hoidon tehoa arvioidaan kirurgisen poiston jälkeen histopatologisesti ja käyttämällä immunohisto-kemiallisia värjäyksiä. |
|
E.2.2 | Secondary objectives of the trial |
To evaluate delayed skin reactions after photodynamic treatment. To investigate occurrence of TERT-mutations in Lentigo maligna. |
Arvioida fotodynaamisen hoidon aiheuttamia jälkireaktioita hoitoalueella. Tutkia TERT-mutaatioiden esiintymistä Lentigo malignoissa. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Patients with non-invasiveLentigo maligna located in the skin of face, neck or upper body region. |
Potilaat, joilla todetaan kasvojen, kaulan tai ylävartalon alueen ei-invasiivinen Lentigo maligna. |
|
E.4 | Principal exclusion criteria |
Biopsy shows invasive melanoma inside Lentigo maligna lesion prior treatment. Porfyria or solar dermatitis. Allergy for
photosensitizers used in study. Pregnant or breastfeeding patients. |
Mikäli ennen hoitoja otetussa koepalassa todetaan invasiivinen melanooma Lentigo malignan alueella. Aiemmin todettu porfyria tai valoihottuma. Allergia käytettävälle
valoherkistäjälle. Raskaana olevat tai imettävät. |
|
E.5 End points |
E.5.1 | Primary end point(s) |

|
E.5.2 | Secondary end point(s) |
To assess delayed skin reactions after photodynamic treatment. To investigate occurrence of TERT-mutations in Lentigo maligna. To control the clinical curing of Lentigo maligna after photodynamic and surgical treatment. |
Arvioida fotodynaamisen hoidon aiheuttamia jälkireaktioita iholla. Selvittää TERT-mutaatioiden esiintymistä Lentigo malignoissa. Kontrolloida Lentigo malignan kliininen paraneminen fotodynaamisten ja kirurgisen hoidon jälkeen. |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
2 weeks (delayed skin reactions). 4 weeks (TERT-mutations). 6 months (clinical curing). |
2 viikkoa (jälkireaktion arvio). 4 viikkoa (TERT-mutaatiot). 6 kuukautta (kliinisen paranemisen kontrolli). |
