Comparative Clinical Trial on Neoviderm Skin Emulsion and Connettivi-na 0.2% Cream to Evaluate the Normalization Process of the Skin and Re-duction of Cutaneous Tension and Pain in Patients With Superficial Burns Grade 1 and 2

It is a single centre, randomized (set up or distributed in a deliberately random way), open-label (study participants and researchers both know which treatment the patient is receiving), prospective, interventional, post-marketing, controlled (An experiment or clinical trial in which two groups are used for comparison purpose), non-inferiority study (a study that tests whether a new treatment is not worse than an active treatment it is being compared to).

The PRIMARY OBJECTIVE is to assess the reduction of skin tension in patients with 1st and 2nd degree superficial burns treated either with Neoviderm Skin Emulsion medical device or Connettivina 0.2% Cream.

Neoviderm Skin Emulsion soothes and relieves the skin, promoting its physiological normalization process. It is suitable for adults, children and infants in case of sunburns; 1st degree and 2nd degree superficial burns; superficial ulcers; protection before and after radiotherapy treatment; skin irritation and manifestations involving redness; skin cracks, including recurring ones; desquamative states; erythema; dry skin; small abrasions. It is also indicated only for adults in case of tattoo aftercare and chemical peel.

Investigation Title:

Comparative clinical trial on Neoviderm Skin Emulsion and Connettivina 0.2% Cream to evaluate the normalization process of the skin and reduction of cutaneous tension and pain in patients with superficial burns grade 1 and 2.

Sponsor:

Istituto Ganassini S.p.A.di Ricerche Biochimiche

Medical Device:

Neoviderm Skin Emulsion - Medical Device class IIb

Intended Use:

Because of its protective and moisturizing action, Neoviderm Skin Emulsion soothes and relieves the skin, promoting its physiological normalization process. It is suitable for adults, children and infants in case of sunburns; 1st degree and 2nd degree superficial burns; superficial ulcers; protection before and after radiotherapy treatment; skin irritation and manifestations involving redness; skin cracks, including recurring ones; desquamative states; erythema; dry skin; small abrasions. It is also indicated only for adults in case of tattoo aftercare and chemical peel.

Background and Rationale:

First degree burns (sometimes also called "superficial" burns) are usually limted to the epidermis, while partial thickness burns (also called 2nd degree burns) involve part of the dermis and can be superficial or deep.

Partial thickness burns involve the papillary dermis (the most superficial portion). These burns heal in 1-2 weeks and the scar is usually minimal. The healing process starts from the cells of the epidermis that line the ducts of the sweat glands and the hair follicles; these cells grow from the surface, migrate along the surface to meet cells from nearby glands and follicles.

Superficial first- and second-degree burns are therefore attributable to minor or minor burns. The severity of the burn also depends on its extent: localized burns are those in which the body surface involved is ≤ 20% in adults, ≤15% in children 10-15 years of age, ≤10 % in children 3-10 years of age and seniors over 65 years of age.

Scientific evidence therefore supports the rationale for developing a medical device (Neoviderm Skin Emulsion) aimed at restoring the integrity of the injured skin by reducing tension and pain, characteristic manifestations of first degree and second-degree superficial burns. Therefore, the study is aimed to evaluate the comparative activity of the Neoviderm Skin Emulsion, Medical Device class IIb and Connettivina 0.2% Cream, OTC product.

Overall Study Design:

It is a single centre, randomized, open-label, prospective, interventional, post-marketing, controlled, non-inferiority study.

PRIMARY OBJECTIVE:

to assess the reduction of skin tension in patients with 1st and 2nd degree superficial burns treated either with Neoviderm Skin Emulsion medical device or Connettivina 0.2% Cream.

SECONDARY OBJECTIVE:

to assess the reduction of pain sensation in patients with 1st and 2nd degree superficial burns treated either with Neoviderm Skin Emulsion medical device or Connettivina 0.2% Cream.

EXPLORATORY OBJECTIVE:

to assess the health status of skin in patients with 1st and 2nd degree superficial burns treated either with Neoviderm Skin Emulsion medical device or Connettivina 0.2% Cream.

Primary Endpoint:

To compare the reduction in skin tension by means of a corneometer, at baseline (V0) and after 14 days of treatment (V2), in patients with 1st and 2nd degree superficial burns treated either with Neoviderm Skin Emulsion medical device or Connettivina 0.2% Cream.

Secondary Endpoint:

To compare the reduction in pain by means of a Visual Analogue Scale (VAS), at baseline (V0) and after 14 days of treatment (V2), in patients with 1st and 2nd degree superficial burns treated either with Neoviderm Skin Emulsion medical device or Connettivina 0.2% Cream.

Exploratory Endpoint:

To assess the health status of the skin, by analysing images obtained through videodermatoscopy at the baseline (V0) and after 14 days of treatment (V2), in patients with 1st and 2nd degree superficial burns treated either with Neoviderm Skin Emulsion medical device or Connettivina 0.2% Cream.

Sample size:

50 subjects (25 subjects treated with Neoviderm Skin Emulsion and 25 patients treated with Connettivina 0.2% Cream).

Dosing:

The two products (Neoviderm Skin Emulsion and Connettivina 0.2% Cream) will be applied twice daily, to cover the entire cutaneous surface interested by burns, followed by a gentle massage to spread the product evenly of all the affected skin.

Statistical Consideration

Decriptive statistics will be summarized, for entire population and separately per treatment groups, according to the type of variable:

* for quantitative variables: standard quantitative statistics (N, mean, standard deviation, median, interquartile range, minimum and maximum);
* for qualitative variables: frequency distribution \[number of non-missing observations (N) and percentages (%)\].

For inferential tests of the difference between groups:

* for quantitative variables (difference of two means or medians): unpaired T-tests (or the corresponding non-parametric Wilcoxon-Mann-Whitney tests, as appropriate) will be performed;
* for qualitative variables (difference of proportions): Chi-Square tests or Fisher's exact tests will be performed.

The number of adverse events (AEs) and the number and proportion of patients with at least one AE will be presented, both for entire population and separately per groups.
