Clinical Trial Summary

The aim was to assess the efficacy and safety of SD-101-6.0 cream versus Placebo (SD-101-0.0) cream in the treatment of skin lesions in participants with Epidermolysis Bullosa. Funding Source - United States Food and Drug Administration (FDA) Office of Orphan Products Development (OOPD).


Description:

This was a Phase 3, multi-center, randomized, double-blind, placebo-controlled study to assess the efficacy and safety of SD-101-6.0 cream versus placebo (SD-101-0.0) cream on skin lesions in participants with Simplex, Recessive Dystrophic, or Junctional non-Herlitz Epidermolysis Bullosa. Epidermolysis Bullosa is a rare group of inherited disorders that typically manifest at birth as blistering and lesion formation on the skin in response to little or no apparent trauma. In this study, SD-101-6.0 cream or placebo (SD-101-0.0) cream was to be applied topically, once a day to the entire body for a period of 90 days. Participants had 1 target wound selected at baseline by the investigator. The selected target wound was required to have been present for at least 21 days. Photographic confirmation of the target wound location was collected at baseline, and the picture saved from the first visit was used to confirm location of the target wound at subsequent visits. The participant returned to the study site for Visit 2 (approximately 14 days from baseline), Visit 3 (approximately 30 days from baseline), Visit 4 (approximately 60 days from baseline), and Visit 5 (approximately 90 days from baseline) to have the target wound assessed for the level of healing. In addition, itching, pain, body surface area, target wound closure, and scarring of healed target wound were assessed at each visit. The ARANZ SilhouetteStarâ„¢ was used to measure the target wound at all visits.

Outcome

Type Measure Description Time frame Safety issue
Primary Time To Complete Target Wound Closure Within 3 Months Target wounds were monitored at each study visit for complete closure, defined as skin re-epithelialization without drainage. Time to target wound closure was measured from the date of the first administration of the study drug to the date of target wound closure. Participants were censored if they did not have a response within 3 months, or withdrew earlier before the confirmation of their target wound closing. This primary end point displays the mean time to complete target wound closure, analyzed using a Kaplan-Meier approach. From baseline to Month 3 visit
Primary The Percentage Of Participants Experiencing Complete Closure Of Their Target Wound Within 3 Months Target wounds were monitored at each study visit for complete closure, defined as skin re-epithelialization without drainage. Participants were considered responders if they experienced complete wound closure at the Week 2 or Months 1, 2, or 3 visits. If a target wound was documented to have closed at a given visit, it was considered closed at all subsequent visits. This primary end point displays the percentage of participants from the ITT population who had complete target wound closure by the end of the study period (that is, 3 months). Analysis was performed on participants with post-baseline wound closure data. From baseline to Month 3 visit
Secondary Percentage Of Participants Experiencing Complete Closure Of Their Target Wound At Month 1 And Month 2 Visits Target wounds were monitored at each study visit for complete closure, defined as skin re-epithelialization without drainage. The percentage of participants who completed target wound closure at the Month 1 and Month 2 study visits is displayed. If a target wound was documented to have closed at a given visit, it was considered closed at all subsequent visits. From baseline to Month 1 and Month 2 visits
Secondary Change From Baseline In Body Surface Area Index (BSAI) Of Lesional Skin At Month 3 Visit Lesional skin was defined as areas that contained any of the following: blisters, erosions, ulcerations, scabbing, bullae, or eschars, as well as areas that were weeping, sloughing, oozing, crusted, or denuded. BSAI was calculated as a percentage, ranging from 0% to 100%, of affected body surface area, recorded for each defined body region (that is, head/neck, upper limbs, trunk [includes groin], and lower limbs), multiplied by the weighting factor, then summed for all body regions. Baseline, Month 3 visit
Secondary Change From Baseline In BSAI Of Total Body Wound Burden At Month 3 Visit Total body wound burden was calculated using BSAI. A wound defined as an open area on the skin (that is, epidermal covering disrupted). BSAI was calculated as a percentage, ranging from 0% to 100%, of affected body surface area, recorded for each defined body region (that is, head/neck, upper limbs, lower limbs, trunk [includes groin]), and multiplied by the weighting factor, then summed for all body regions. Baseline, Month 3 visit
Secondary Change From Baseline In Itching Score At Day 7 Itching was assessed using the 5-point Itch Man Pruritus Assessment Tool. For participants up to 5 years of age, itching was assessed using caretaker's response and participants 6 years of age and older self-reported their itching assessments based on the following scores: 0=Comfortable, no itch; 1=itches a little, does not interfere with activity; 2=itches more, sometimes interferes with activity; 3=itches a lot, difficult to be still, concentrate; 4=itches most terribly, impossible to sit still or concentrate. Itching scores were categorized into 3 groups based on improvement; Improved or No Itching, Not Improved, and Missing. An itching score reduction from baseline greater than or equal to 1 point on the scale was classed as improved. Baseline, Day 7
Secondary Change From Baseline In Pain Score At Day 7 Change in pain assessed at Day 7 compared to baseline was measured using the Face, Legs, Activity, Cry, and Consolability (FLACC) behavioral scale for participants 1 month to 3 years of age. Each of the 5 FLACC categories was scored from 0 to 2, which resulted in a total score between 0 and 10 with 0=Relaxed and comfortable, 1 to 3=Mild discomfort, 4 to 6=Moderate pain, and 7 to 10=Severe discomfort/pain. For participants 4 years of age and older, the "Wong Faces Pain Scale" was used. This scale shows a series of faces ranging from a happy face at 0, which represents "no hurt," to a crying face at 10, which represents "hurts worst". Pain scores were categorized into 3 groups based on improvement: Improved or No Pain, Not Improved, and Missing. A pain score reduction from baseline greater than or equal to 2 points on the scale was classed as improved. Baseline, Day 7
