About this study

Official title: Evaluation of the Tolerance and the Mode of Administration of Cyto-selective Difluoroethane-based Cryotherapy in the Treatment of Brown Spots

Solar lentigos or lentigines are harmless patch of darkened skin, of different sizes and colors, due to the exposure to UV radiation. They are very common, especially in people over the age of 40 years old. Solar lentigines appears as clusters of similar lesions on sun-exposed sites, such as the face or the back of the hands.

Conventional cryotherapy is increasingly used to improve the skin appearance and especially to treat lentigo spots. However, the application of conventional cryotherapy is followed by temporary side effects including pain at application, hypo- and hyperpigmentation, crust, scars, burns, erythema... for a few days after administration and that can persist during several months.

In this context, the sponsor has developed a treatment using cyto-selective cryotherapy, that treats only the melanocytes responsable of brown spots while preserving other cells of the epidermis. Several sequences of pulverization of cryogenic gas have been designed. It seems interesting for the sponsor to study some ways of applications of the selected sequences. i.e. 5 conditions evaluated) that could be used for the treatment of lentigos with the same clinical benefit and with better safety results for patients .

(CS4_2) proof of concept, interventional, monocentric, randomized and double blinded study, aims to evaluate the tolerance and the mode of administration of cyto-selective difluoroethane-based cryotherapy in the treatment of brown spots.

The main objective of the study is to evaluate the tolerance and to adjust the mode of administration of 3 different cryotherapy treatments (3 prototypes) applied on the brown spots of the face. Each treatment corresponds to a specific sequence of a cryogenic spray.

Read the detailed description

Prototypes (810A-v1), (810B-v1) and (810C-v1) will be applied on brown spots located on the face. Regarding the randomization list, each spot will be treated by a defined prototype / device (same prototype /device will be used to treat the same spot all along the study).

Each spot will be treated 6 times during the study:

  • At Day 0, Day 1, Day 2, Day 3 Day 4 and Day 5 for the prototypes (810A-v1) (condition 1) and (810B-v1) (condition 2).
  • At Day 0, Day 7, Day 14, Day 21, Day 28 and Day 35 for the prototypes (810A-v1) (condition 3) and (810C-v1) (condition 4).
  • At Day 0, Day 14, Day 28, Day 42, Day 56 and Day 70 for the prototype (810C-v1) (condition 5, considered as reference).

Prior to any study device application, the dermatologist will assess the adverse events and decide whether the period between two consecutive applications should be extended or not. The dermatologist will verify that the skin has not been treated with cosmetic products (no cream, peeling, dermabrasion, laser treatment... that could interfere with the treatment) and that is dry.

The procedure will take place at the investigation site. An operator previously trained by the dermatologist will apply the study device to the patient's brown spots.

Subjects will lie down and the device will be administered upside down. During the applications, subjects will wear diving goggles (provided by the CRO) to protect the eyes from the cryogenic gas.

Treatments will be stopped when a total of 6 applications for the prototypes will be delivered or as soon as a spot will be considered disappeared by the investigator. Otherwise the study will continue (tolerance report, etc.) until all conditions are completed.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change from baseline skin hyperpigmentation

    This outcome is a tolerance assessment criteria. Clinical evaluation of hyperpigmentation on each selected and treated lentigo spot will be performed by a Dermatologist using the Investigator's Global Assessment likert 6 points scale ranged from 0 to 5: 0=Clear of hyperpigmentation, 1= Almost clear of hyperpigmentation, 2=mild, but noticeable hyperpigmentation, 3=moderate hyperpigmentation (medium brown in quality), 4=severe hyperpigmentation (dark brown in quality), 5= very severe hyperpigmentation (very dark brown, almost black in quality).

    Measured: - Conditions 1 and 2: Day0, Day1, Day2, Day3, Day4, Day5, Day14 and Day28 - Conditions 3 and 4: Day0, Day1, Day2, Day3, Day7, Day14, Day21, Day28, Day 35 and Day42 - Condition 5 (Ref): Day0, Day1, Day2, Day3, Day14, Day28, Day42, Day56, Day70 and Day84

  2. Change from baseline skin hypopigmentation

    This outcome is a tolerance assessment criteria. Clinical evaluation of hypopigmentation on each selected and treated lentigo spot will be performed by a Dermatologist using a likert 5 points scale ranged from 0 to 4: 0=no hypopigmented lesion, 1= very slight area of hypopigmentation of very small size and very slightly fairer than the surrounding skin, 2= slight area of hypopigmentation of small size and slightly fairer than the surrounding skin, 3= moderate : area of hypopigmentation of moderate size and much fairer than the surrounding skin, 4= severe : area of hypopigmentation of large size and much fairer than the surrounding skin.

    Measured: - Conditions 1 and 2: Day0, Day1, Day2, Day3, Day4, Day5, Day14 and Day28 - Conditions 3 and 4: Day0, Day1, Day2, Day3, Day7, Day14, Day21, Day28, Day35 and Day42 -Condition 5 (Ref): Day0, Day1, Day2, Day3, Day14, Day28, Day42, Day56, Day70 and Day84

  3. Change from baseline skin appearance (Edemas, blisters, bubbles, scars, erythema)

    This outcome is a tolerance assessment criteria. Clinical visual evaluation of selected lentigo spots and surrounded spotless skin area around the spot skin will be performed. A likert scale in 5 points (0 to 4) will be used : 0=none; 1=very mild; 2=mild; 3=moderate; 4=severe.

    Measured: - Conditions 1 and 2: Day0, Day1, Day2, Day3, Day4, Day5, Day14 and Day28 - Conditions 3 and 4: Day0, Day1, Day2, Day3, Day7, Day14, Day21, Day28, Day35 and Day42 -Condition 5 (Ref): Day0, Day1, Day2, Day3, Day14, Day28, Day42, Day56, Day70 and Day84

  4. Change from baseline skin sensation (itching, tingling, burning sensations)

    This outcome is a tolerance assessment criteria. Clinical visual evaluation of selected lentigo spots and around the spot skin will be performed. A likert scale in 5 points (0 to 4) will be used : 0=none; 1=very mild; 2=mild; 3=moderate; 4=severe.

    Measured: - Conditions 1 and 2: Day0, Day1, Day2, Day3, Day4, Day5, Day14 and Day28 - Conditions 3 and 4: Day0, Day1, Day2, Day3, Day7, Day14, Day21, Day28, Day35 and Day42 -Condition 5 (Ref): Day0, Day1, Day2, Day3, Day14, Day28, Day42, Day56, Day70 and Day84

  5. Post treatment pain

    This outcome is a tolerance assessment criteria. The pain of the treatment will be assessed by the VAS (Visual Analogue Scale). Pain intensity is measured in millimeters by the distance from the position of the mark to the "no pain" extremity.

    Based on the distribution of pain VAS (Visual Analogue Scale) scores in postoperative patients, the following bounds were recommended for the assessment of this scale: no pain (0-4mm), mild pain (5-44mm), moderate pain (45-74 mm) and severe pain (75- 100 mm).

    Measured: Day 0 (Time1 defined as 15 minutes post-treatment)

  6. Change from baseline skin color

    This outcome is a performance assessment criteria. Clinical evaluation of each treated lentigo spot and spotless area (one on face and far from a lentigo spot) will be performed in blinded conditions by a trained assessor by scoring using L'OREAL ColorChart (provided by the Sponsor or L'Oréal) in standardized position and lighting.

    Measured: - Conditions 1 and 2: Day0, Day14 and Day28 - Conditions 3 and 4: Day0, Day7, Day14, Day21, Day28, Day35 and Day42 - Condition 5 (Ref): Day0, Day14, Day28, Day42, Day56, Day70 and Day84

  7. Change from baseline spots visibility

    This outcome is a performance assessment criteria. Standardized photographs by C-Cube® acquisition will be taken before the treatment at each visit of each spot using a dermatoscope C-cube (device which allows realizing high resolution skin pictures (10 million pixels 2D capture (UHD)).

    Measured: - Conditions 1 and 2: Day0, Day1, Day2, Day3, Day4, Day5, Day14 and Day28 - Conditions 3 and 4: Day0, Day1, Day2, Day3, Day7, Day14, Day21, D28, Day35 and Day42 - Condition 5 (Ref): Day0, Day1, Day2, Day3, Day14, Day28, Day42, Day56, Day70 and Day84
