Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
A combination of three bacterial strains (SVT9, SVT23 and SVT26) at a concentration of 2.5 billion CFU/mL per bacterial strain in a carrier of sterile saline solution.

The study medication is topically applied (sprayed) to a specified active dermatitis lesion at a dose of 2 x 0.2 mL (0.4 mL per dose; 3 billion CFU/0.4 mL) twice per day (morning and evening) after showering, leaving at least 6 hours between applications. The moistened skin is to dry naturally and not rubbed. The spray cap provides a precise 0.2 mL dose per spray.
The duration of administration is for 21 days.

Monitoring participant adherence in applying the 2 sprays twice per day will be done via the participant recording each time they apply the spray in a paper diary that will be provided. Diaries will be provided at baseline, Day 7 and Day 14 providing 3 diaries in total and the investigator will collect the diaries at each visit.
Intervention code [1] 301500 0
Treatment: Drugs
Comparator / control treatment
The study involves a single group only. The participant will treat one active dermatological lesion with the treatment medication and a contralateral lesion i.e. crease in opposite elbow or knee will be used as a control lesion in which the participant can only apply their normal daily moisturiser to it. They will not be allowed to apply any topical medications to their control contralateral lesion.
Control group
Active

Outcomes
Primary outcome [1] 306243 0
1. Target lesion local objective SCORing Atopic Dermatitis (SCORAD) that will assess the clinical signs and symptoms of the target lesion and control lesion and to monitor changes in disease severity.
Timepoint [1] 306243 0
Baseline, Day 7, Day 14 and Day 21
Primary outcome [2] 306244 0
Sampling and quantification of Staphylococcus aureus colonisation on the target and contralateral lesions. Sampling will be conducted via the swab method and identification and quantification will be done at Sullivan & Nicolaides Pathology.
Timepoint [2] 306244 0
Baseline and Day 21
Secondary outcome [1] 347971 0
A composite secondary outcome is the cutaneous tolerability of treatment that will be assessed by the investigator at each visit. Tolerability will be based on signs of erythema, induration or papulation, oozing or crusting, excoriation, lichenification and pruritus in the target lesion. All signs classified according to intensity (0=none, 1=mild, 2=moderate and 3=severe)

Day 7, Day 14 and Day 21

Eligibility
Key inclusion criteria
Male and female participants aged 6 years and older diagnosed (as per Rajka-Hanifin criteria) with AD of mild-to-moderate severity at baseline (Investigator Global Assessment of 2 or 3) who exhibit at least two AD lesions of a dimension greater than or equal to 20 cm2. The locations of AD lesions need to allow for accurate sampling. The lesional skin is defined as an active lesion of AD: an erythematous plaque with or without oozing, vesiculation, crusting, excoriations, or erosions but with no overt sign of infection, located within the antecubital or popliteal fossae, or other region typical of AD. Women of child bearing age must have a negative pregnancy test at baseline. Participants and guardians will need to be capable of providing informed consent and comply with the study instructions.
Minimum age
6 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Severe fungal infection or other skin disease that could affect AD diagnosis; uncontrolled or serious disease, or any condition that could interfere with data interpretation or put the participant at significant risk; recent use of other investigational drugs or procedures; participants who cannot adhere to refraining from using topical steroids, antibiotics or antiseptics on the two treated lesions only (treatment and control) for the study duration (topical medications can be used elsewhere on the body if required); participants who cannot adhere to refraining from consuming oral steroids or antibiotics. Also those who cannot abstain from the intake of probiotic supplements and foods from induction (Day 0) into the study and for the duration of the study will be excluded

Other
Other design features
Participants will act as their own control in which two lesions will be chosen by the investigator and one lesion will designated the 'active treatment' lesion and the other designated the 'control' lesion. The participants are not permitted to apply any topical medications such as steroids and antibiotics to either of the two lesions, and only SVT-XCLEAR can be applied to the active treatment lesion and only the participants daily moisturiser can be applied to the control lesion if required..

Summary
Brief summary
Study Design: Single centre, open-label, single arm exploratory study

Study drugs: A combination of three bacterial strains (SVT9, SVT23 and SVT26) at a concentration of 2.5 billion CFU/mL per bacterial strain in a carrier of sterile saline solution.

Dose and duration: The study medication is topically applied (sprayed) to a specified active dermatitis lesion at a dose of 2 x 0.2 mL (0.4 mL per dose; 3 billion CFU/0.4 mL) twice per day (morning and evening) after showering, leaving at least 6 hours between applications. The moistened skin is to dry naturally and not rubbed. The spray cap provides a precise 0.2 mL dose per spray. The duration of administration is for 21 days.

Objectives of the Study: Feasibility of methods and procedures, recruitment potential, increase clinical experience of study medication; evaluate surrogate marker data in a small patient cohort to assess if it will be therapeutically effective and safe for further larger studies.

Study Endpoints: Primary outcome measures will include assessment of treatment efficacy using 1. Target lesion local objective SCORing Atopic Dermatitis (SCORAD) that will assess the clinical signs and symptoms of the target lesion and control lesion and to monitor changes in disease severity; 2. Sampling and quantification of S. aureus colonisation on the target and contralateral lesion.

Secondary outcome measures: 1. Cutaneous tolerability of treatment based on signs of redness, dryness, crusting, weeping, peeling, thickening and itching of the target lesion. All signs classified according to intensity (0 = none, 1 = mild, 2 = moderate and 3 = severe).
