Brief Summary:
This study compares the efficacy and tolerance of a new device (FLEXITHERALIGHT) for photodynamic therapy in the treatment of keratosis actinic in comparison of classical PDT with Aktilite®.

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

Detailed Description:

The study is an intraindividual comparison of two methods. The number of subjects to be enrolled is 47 patients. All participants will receive both two treatments in a single visit : a first period of 2.5 hours of illumination with FLEXITHERALIGHT device followed by a continuous red light Spectrum (between 7 and 10 minutes) with Aktilite® after an appropriate incubation of methyl aminolevulinate).

Patients will complete a pain assessment scale after receiving both treatments, then, 3 follow up visits will be scheduled.

Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase II Study Evaluating the Non-inferiority of the Device FLEXITHERALIGHT Compared to the Conventional Photodynamic Therapy (PDT)
Actual Study Start Date : September 2014
Actual Primary Completion Date : February 2017
Actual Study Completion Date : February 2017

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

Light Emitting Textile Device
Preparation of lesions, MAL 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: Day 1 and D ay 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: Months 3 and Months 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. Fluorescence measure of the PpIX [ Time Frame: Baseline, after 3 hours of incubation, in case of treatment interruption, immediately after the treatment, and at 15 and 30 minutes after the end of the treatment. ]
    Measures with Fluoderm photometer

  4. Irradiance measure in mW/cm2 for each AK [ Time Frame: during Aktilite® treatment at Day 1 ]
    Measures realised with a wattmeter OPHIR LaserSTAR to know the power of light delivered

  5. Rate of patients with at least 75% of reduction of the lesions [ Time Frame: Months 3 and Months 6 ]

    The reduction in the number of lesions will be calculated as a function of the initial number:≥4 destroyed if 5 lésions; ≥ 5 destroyed if 6 lésions and ≥6 destroyed if 7 lesions

    ≥4 destroyed if 5 lesions

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

  7. Satisfaction Questionnaire [ Time Frame: At Day 7, Months 3 and Months 6 ]
    The questionnaire es created by the investigator to evaluate the comfort of the device. Patient will give his overall satisfaction and the will answer 7 questions on a 5-point scale that ranged from Not embarrassing, few embarrassing, embarrassing, Very embarrassing, I 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.
  • 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 10mm 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, any - Patients receiving topical treatment (including imiquimod, 5-FU and diclofenac, Picato) in face / scalp area within the last 3 months.
  • Use of topical retinoids or alpha-hydroxy acids, urea or systemic retinoids, chemotherapy or immunotherapy within 4 weeks of PDT.
  • Pigmented AK lesion(s).
  • Known allergy to Metvixia, 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 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
