Brief Summary:
This study aims to compare the efficacy and tolerance of a new photodynamic therapy device (PHOS-ISTOS) with the conventional PDT device (Aktilite®) for the treatment of actinic keratosis of the scalp

Condition or disease Intervention/treatment Phase
Keratosis, Actinic Device: Aktilite® Galderma Device: PHOS ISTOS PDT Not Applicable

Detailed Description:
The study is an intraindividual comparison of two methods. The number of subjects to be enrolled is 47. Patients will receive both treatments in a single visit: A first period of 2.5 hours of illumination with Phos-Istos device followed by a continuous red light spectrum (between 7 and 10 minutes) with Aktilite® after an appropriate incubation of MAL (methyl aminolevulinate). Patients will complete a pain assessment scale after receiving both treatments. 3 follow-up visits will be then scheduled

Allocation: Randomized
Intervention Model: Sequential Assignment
Intervention Model Description: Split Face intra individual comparison
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase II Study Evaluating the Non-inferiority and Better Tolerability of the Device PHOS-ISTOS Compared to the Conventional Photodynamic Therapy (PDT)
Actual Study Start Date : September 2016
Actual Primary Completion Date : November 2017
Actual Study Completion Date : November 2017

Arm Intervention/treatment
Active Comparator: Conventional PDT
Aktilite® Galderma
Device: Aktilite® Galderma
preparation of the lesions, Metvixia application + occlusive dressing during 3 hours + illumination: 7 to 10 minutes
Other Name: Conventional PDT

Experimental: PHOS ISTOS PDT
Light Emitting textile device
preparation of the lesions, Metvixia application + occlusive dressing during 30 minutes + illumination: 2.5 hours

Primary Outcome Measures :
  1. Treated lesion response rate [ Time Frame: up to Month 6 ]
    Each treatment area will be counted, graded with Clinical grade of AK, mapped and photographed

Secondary Outcome Measures :
  1. Visual analog scale of pain [ Time Frame: at Day 1 and Day 7 ]
    measure the pain and local tolerance graduation range 0 to 10.

  2. Scale for clinical assessment of the subject's skin aspect [ Time Frame: at Month 3 and Month 6 ]
    4-point scale that ranged of Excellent :No scarring, atrophy or induration, and no or slight occurrence of redness or change in pigmentation compared to adjacent skin Good: No scarring, atrophy or induration but moderate redness or change in pigmentation compared to adjacent skin Fair: Slight to moderate occurrence of scarring, atrophy or induration Poor : Extensive occurrence of scarring, atrophy or induration

  3. Rate of patients with at least 75% of reduction of the lesions [ Time Frame: at Month 3 and Month 6 ]
    The response rate is calculated in relation to the initial number of lesions: Response rate is validated if rate ≥ 4 lesions destroyed for 5 initial lesions, ≥ 5 for 6 lesions and ≥ 6 for 7 lesions

  4. Dermatology Life Quality Index (DLQI ) [ Time Frame: at day 1 , Day 7, Month 3 and Month 6 ]
    The questionnaire of 10 questions is completed by the patient to evaluate his quality of life

  5. Satisfaction autoquestionnaire [ Time Frame: at Day 7, Month 3 and Month 6 ]

    The questionnaire is created by investigator to evaluate the comfort of device.

    Participants will answer 9 questions on a 5-point scale that ranged from Not embarrassing,few embarrassing, Embarrassing, Very embarrassing, Don't know

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Clinical diagnosis of minimum 10 previously untreated not pigmented, non-hyperkeratotic AK lesions of Grade I and II of the forehead and/or scalp (according to Olsen et Al. JAAD 1991, cf. REF 31) where other therapies are unacceptable or considered medically less appropriate with a symmetrical repartition on both side of the forehead and/or scalp. The diagnosis of AK will be determined upon clinical evaluation (i.e. visual inspection and palpation) by the investigator.
  • No treatment for the AKs in the previous 30 days.
  • Symmetrical areas in terms of number and severity of lesions. The axis of symmetry between the two areas will be defined by the investigator according to the distribution of lesions.
  • The two areas to be treated should not be coalescing. A minimum distance of 10 mm is required between the lesions located on the 2 symmetrical areas. A minimum distance of 2 mm is required between the lesions on the same side.
  • Minimum 5 lesions with similar dimensions at both symmetrical areas will be treated. If the number of lesions is >7, only 7 lesions on each side will be considered.

Exclusion Criteria:

  • Patients with porphyria.
  • Patients immunosuppressed for idiopathic, disease specific or therapeutic reasons.
  • Use of topical corticosteroids to lesional areas within 2 weeks before PDT.
  • Patients receiving local treatment (including cryotherapy and curettage-electrocoagulation, any PDT treatment) in face / scalp area within the last 30 days.
  • Patients receiving topical treatment (including imiquimod, 5-FU and diclofenac, Picato) in face / scalp area within the last 30 days.in
  • Use of topical retinoids or alpha-hydroxy acids, systemic retinoids, chemotherapy or immunotherapy within 30 days of PDT.
  • Pigmented AK lesion(s).
  • Known allergy to Metvixia/Metvix, a similar PDT compound or excipients of the cream including arachis oil, or to peanut or soya.
  • Participation in other clinical studies either currently or within the last 30 days.
  • Female subjects must be of either:

    • Non-childbearing potential, i.e. post-menopausal or have a confirmed clinical history of sterility (e.g. the subject is without a uterus) or,
    • Childbearing potential, provided there is a confirmed negative urine pregnancy test or blood analysis prior to study treatment, to rule out pregnancy.
  • Any condition which may be associated with a risk of poor protocol compliance.
  • Patients currently receiving regular ultraviolet radiation therapy.
