Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Aim of the study: To evaluate clinical effectiveness of two different light doses when treating actinic keratoses with photodynamic therapy with 20% 5-aminolevulinic acid.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

To determine and compare clinical and histological effectiveness of different (70 J/cm2 ir 100 J/cm2) light doses when treating actinic keratoses with photodynamic therapy.

To determine pain intensity during photodynamic therapy with visual analogue scale and factors influencing pain during the procedure.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Group I

Patients with actinic keratosis (AK) on the left and right sides of face/scalp region treated with photodynamic therapy using 20% 5-aminolevulinic acid.

Group Type ACTIVE_COMPARATOR

Photodynamic therapy with light dose of 70 J/cm2 using a broad-band red light source

Intervention Type DEVICE

Patients take part in intraindividual (left-right) comparison study when having at least 2 non-hyperkeratotic actinic keratoses (AK) on the left and right sides of the face/scalp.

Punch biopsies in 3.5 millimetres diameter performed to confirm the diagnosis of AK.

Patients randomized so that half of them would receive a light dose of 70J/cm2 as their first split face/scalp treatment on the left side. Photodynamic therapy with the light dose of 70 J/cm2 using a broad-band red light source (570-670 nm,Curelight®, PhotoCure, Oslo, Norway) and 20% 5-ALA. Treatment repeated twice with two weeks interval.

Group II

Patients with actinic keratosis (AK) on the left and right sides of the face/scalp region treated with photodynamic therapy using 20% 5-aminolevulinic acid.

Group Type ACTIVE_COMPARATOR

Photodynamic therapy with 100J/cm2 light dose using a broad-band red light source

Intervention Type PROCEDURE

Patients take part in intraindividual (left-right) comparison study when having at least 2 non-hyperkeratotic actinic keratoses (AK) on the left and right sides of the face/scalp. Punch biopsies in 3.5 millimetres diameter performed to confirm the diagnosis of AK.

Patients randomized so that half of them would receive a light dose of 100J/cm2 as their first split face/scalp treatment on the left side. Photodynamic therapy with the light dose of 70 J/cm2 using a broad-band red light source (570-670 nm,Curelight®, PhotoCure, Oslo, Norway) and 20% 5-ALA.Treatment repeated twice with two weeks interval.
