Clinical Investigation to Evaluate the Safety and Performance of ConnettivinaBio Plus Cream Compared to ConnettivinaBio Cream in the Management of Wounds in Patients at High Risk of Infection
Study Details
Study Description
Brief Summary
The clinical investigation plan will include a Screening/Baseline visit (V1) in which patients will be screened on the basis of inclusion/exclusion criteria and clinically evaluated. Screened and eligible patients will be randomly assigned in one of the two groups: Group 1 will receive ConnettivinaBio Plus cream whereas Group 2 will receive ConnettivinaBio cream. Lesions will be cleaned and a photo will be acquired with a digital camera.
In both groups, the schedule treatment will consist of daily medication changes.
Wound Bed Score, clinical signs of localized infection, measurement of the wound area, collection of the swab, according to the Levine's technique, EQ-5D questionnaire to the patient will be assessed on Day 1 (V1, baseline visit), 7 (V2), 14 (V3), 21 (V4) and 28 (V5) post-baseline. Treatments in both groups (ConnettivinaBio Plus or ConnettivinaBio) will be applied for a maximum period of 28 days. The easiness of treatment application will be also recorded at V5.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Group 1 ConnettivinaBio Plus cream ConnettivinaBio Plus cream is a topical preparation constituted by Principal component: Hyaluronic acid sodium salt 0.2% Other components: Silver Sulfadiazine 1%, The medication should be applied once a day as a thin layer to cover the entire surface of the wound previously cleansed |
Device: ConnettivinaBio Plus cream
The Un-blinded Investigator will perform the first application of medication. He will also instruct the patient or his/her caregiver to the self-application of the treatment which will be covered by a secondary dressing according to the site's standard care.

Outcome Measures
Primary Outcome Measures
- improving the wound's bed conditions in wounds at high risk of infection, after 14 days of treatment, compared to ConnettivinaBio cream [at day 14]
The amelioration of wound's bed conditions will be evaluated by measuring the proportion of patients having an increase of at least one subclass of the Wound Bed Score (WBS) Falanga V, 2006) from baseline to 14 days of treatment with ConnettivinaBio Plus cream compared to ConnettivinaBio cream.
Secondary Outcome Measures
- improving the wound bed condition [At days 7, 21 and 28]
The amelioration of the wound bed conditions will be evaluated: - by measuring the proportion of patients having an increase of at least one subclass of the WBS from baseline to 7, 21 and 28 days of treatment with ConnettivinaBio Plus cream compared to ConnettivinaBio cream;
- improving the wound bed condition [At days 7, 14, 21 and 28]
The amelioration of the wound bed conditions will be evaluated: - by measuring the percentage change from baseline in the WBS after 7, 14, 21, and 28 days of treatment with ConnettivinaBio Plus cream compared to ConnettivinaBio cream.
- control of bacterial load of wounds [At days 7, 14, 21 and 28]
The performance of ConnettivinaBio Plus in the bacterial load control will be evaluated by measuring the change from baseline of CFU/ml derived from the culture of a swab collected according to the Levin's technique, after 7, 14 and 28 days of treatment and compared to ConnettivinaBio cream
- control on signs of wound infection [At days 7, 14, 21 and 28]
Difference in the performance of ConnettivinaBio Plus, compared to ConnettivinaBio, with respect to clinical signs of wound infection. The appearance and/or modification of signs of infection will be evaluated as percentage change from baseline at all visits. The evaluation will be carried out calculating the clinical wound's infection score through an 18-point scale, based on the presence and intensity of the following clinical signs: fever, local heat, peri-lesional erythema, persistent pain (between two dressing changes), oedema, malodour, pus and exudate production (Cutting KF, 1994; Trial C, 2010).
- improving the reepithelization rate [At days 7, 21 and 28]
The reepithelization rate will be evaluated as the difference in the mean percentage reduction of lesion area from baseline between patients treated with ConnettivinaBio Plus versus ConnettivinaBio at all the visits by using a computerized image software (Chang AC, 2011) and as a distribution of percentage reduction in the following classes: ≤25%; >25% and ≤50%; >50% and ≤75%; >75% and ≤95%; >95% and ≤100% of the lesion area.
- improving patient's quality of life [At days 7, 14, 21 and 28]
Patient's quality of life assessment will be evaluated as a change from baseline after 7, 14, 21 and 28 days, through administration of EuroQoL-5D (EQ-5D)
- clinician's global assessment of the lesion [At days 7, 14, 21 and 28]
Clinical Global Assessment (CGA) will be evaluated at each post baseline visit: the clinician will be requested to score the lesion on a five grade scale: 1= worsening, 2= no change, 3= minimal improvement, 4= moderate improvement and 5= good improvement
- easiness of the treatment application [at day 28]
The easiness of the treatment application will be appraised by the Un-blinded Investigator and by the patient after 28 days as excellent, good, acceptable, bad or unacceptable.
- evaluation of the safety and tolerability of treatment: adverse events [throughout study completion, an average of 1 year]
The safety and tolerability of treatment will be assessed by investigating local and expected adverse events, as consequence of the product application and any other adverse event occurred during the study
