Clinical Trial Summary

The purpose of this study is to examine the safety and effectiveness of a new therapy, commensal lotion containing infection fighting bacteria, on decreasing or eliminating the infection causing bacteria found on the skin of Atopic Dermatitis (AD) patients.

Description:

This study will enroll adult participants, 18-60 years of age, with moderate-to-severe atopic dermatitis (AD) and a positive Staphylococcus aureus (S. aureus) colonized lesion (at least 15 cm^2 in size) on the upper extremities.

Participants who are eligible based on their positive Staph culture results will be randomized to one of two treatments: Targeted Microbiome Transplant Lotion (TMT) or Placebo (2:1 randomization). One lesional site measuring at least 15 cm^2 and one non-lesional site of equal size will be identified on the participant's ventral upper extremities as the target swabbing areas. These sites will be photographed and marked for swabbing for reference at the participant's future visits. Participants will be instructed to apply investigational product with gloved hands to their ventral upper extremities bilaterally from the wrist to the upper humerus, which will include the identified lesional and non-lesional swabbing sites twice a day for 1 week starting on Day 0. Participants will return to clinic on Day 4 for the assessment of adverse events, the collection of skin swabs from the identified target sites, and to obtain additional investigational product and gloves. Participants will complete an additional clinic visit on Day 7 to correspond with the end of their 1 week treatment. During this visit, participants will be assessed for AEs and provide skin swab samples. All unused product and empty packets will be returned during the Day 4 and Day 7 visits. Three additional clinic visits on Days 8, 9, and 11 will be scheduled for additional skin swabs to assess the safety and the stability of the microbiome transplant and time to recurrence of Staph colonization. Participants will be followed through Day 38 to assess for safety and disease status.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Per-Participant Daily Event Rate: Serious and Non-Serious Treatment Emergent Adverse Events (TEAEs)	Per-participant daily event rate of TEAEs was calculated as the number of events per-participant-days at risk. Statistical method employed: Poisson generalized linear model with a log link function and including the natural log of the number of days active in the study during Day 0 to Day 8.	Day 0 to Day 8
Secondary	The Occurrence of at Least One Serious or Non-Serious Treatment Emergent Adverse Event (TEAE)	The number of participants for which at least one treatment emergent adverse event (AE), defined as an increase in grade from baseline or from the last post-baseline value that does not meet grading criteria, was reported during the measure time frame.	Day 0 (after initiation of study treatment) through Day 8 (last day of study treatment)
Secondary	Per-Participant Daily Event Rate of Serious and Non-Serious Adverse Events (AEs)	Per-participant daily event rate of serious and non-serious AEs was calculated by the number of events per-participant days active in the study during Screening to Day 38.	Screening (up to 38 days before initiation of treatment) to Day 38 (last day of study participation)
Secondary	The Occurrence of at Least One Serious or Non-Serious Adverse Event (AE)	The number of participants for which at least one adverse event (AE) was reported	Screening (up to 38 days before initiation of treatment) to Day 38 (last day of study participation)
Secondary	The Eczema Area and Severity Index (EASI) Score of the Ventral Arms at Specific Days During the Measure Time Frame	The eczema area and severity index (EASI) for the ventral arms is a composite score measuring physical signs of atopic dermatitis. The scale ranges from 0-18. The components measuring severity are four signs/symptoms of atopic dermatitis: erythema, papulation, excoriation, and lichenification each scored on a scale of 0 (absent) to 3 (severe) for the ventral arms. The component measuring area is the percent area of the ventral arms with atopic dermatitis lesions scored on a scale of 0 (0%) to 6 (90-100%).	Days 0, 4, 7, 8 and 11
Secondary	The Scoring Atopic Dermatitis (SCORAD) Score at Specific Days During the Measure Time Frame	SCORAD (Severity scoring of Atopic Dermatitis) is a composite severity index comprising A) the amount/extent of body surface area affected; A= 0-100%, B) disease intensity assessed as sum of scores for 6 parameters (erythema, edema/papulation, oozing/crusting, excoriation, lichenification, and dryness), each graded from 0 (none) to 3 (severe); B= 0-18, and C) subjective symptom visual analog assessments for pruritus [0 (no itch) to 10 (worst imaginable itch)] and sleep loss [0 (no sleep loss) to 10 (worst imaginable sleep loss)] summed for a total symptom score; C=0-20. The SCORAD = A/5 + 7B/2 + C and ranges from 0 (no AD present) to 103 (severe).	Days 0, 4, 7, 8 and 11
Secondary	The Rajka-Langeland (RL) Score at Specific Days During the Measure Time Frame	The Rajka & Langeland (RL) eczema severity score is a simple assessment of AD severity as well as the classification of AD into mild, moderate, or severe. The score is based on the grading of: (i) eczema extent based on % body area affected, (ii) eczema course based on the number of months with remission during the previous year, and (iii) eczema intensity expressed in terms of nocturnal sleep disturbance due to itch. Each parameter is scored on a scale from 1-3, and the scores are summed. The RL score ranges from 3 to 9 (mild, 3-4; moderate, 4.5-7.5; severe, 8-9)	Days 0 and 7
Secondary	The Pruritus Visual Analog Scale (VAS) Score of the Ventral Arms at Specific Days During the Measure Time Frame	The pruritus visual analog scale (VAS) asks participants to rate the status of their Pruritus based on the severity of their itch. Scores range from 0 to 10 (0 = no itch, 10 = worst imaginable itch)	Days 0, 4, 7, 8 and 11
