About this study

Official title: Double-blind, Randomised, Vehicle-controlled, Phase III, Efficacy and Safety Study With 24-month Open-label Follow-up of Oleogel-S10 in Patients With Inherited Epidermolysis Bullosa

This was a Phase III, Efficacy and Safety Study of Oleogel-S10 in Participants with Inherited Epidermolysis Bullosa (EB).

EB is a rare group of genetic skin fragility disorders characterised by blistering of the skin in response to minor injury. In most cases, onset of EB is at birth or shortly after. All participants affected by any type of EB share the main characteristic of repeatedly developing painful wounds that take days to months to heal. Current treatment of EB is primarily preventative and supportive including protection from mechanical forces by avoiding rubbing, early treatment of wounds to prevent infections, and protection of the wound with adequate non-adhesive dressings to enable healing.

The active pharmaceutical ingredient in Oleogel-S10 is a refined birch bark extract, quantified to 72 to 88% betulin.

This clinical study of Oleogel-S10 in patients with inherited EB has been carried out to investigate whether Oleogel-S10 is effective for treatment of EB wounds and safe for long-term use.

Oleogel-S10 was compared to a control gel. The control gel matched Oleogel-S10 in terms of texture and visual appearance to allow for double-blinding. The packaging for Oleogel-S10 gel and the control gel were identical. The participant received either Oleogel-S10 or control gel for a double-blind study phase of 90 days. The probability that the participant received Oleogel-S10 was 50%, which means that they had a 1 in 2 chance of receiving Oleogel-S10. However, in the follow-up phase of the study all participants were treated with Oleogel-S10 for a period of 24 months.

This clinical study was performed at 49 study sites in 26 countries (Argentina, Australia, Austria, Brazil, Chile, Colombia, Czech Republic, Denmark, France, Georgia, Germany, Greece, Hong Kong [China], Hungary, Ireland, Israel, Italy, Romania, Russia, Serbia, Singapore, Spain, Switzerland, Ukraine, United Kingdom, and the United States); 223 participants participated in total.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Proportion of Patients With First Complete Closure of the EB Target Wound Within 45 Days of Treatment

    Proportion of subjects with first complete closure of the EB target wound (defined as EB partial-thickness wound of 10 cm2 to 50 cm2 in size and ≥21 days to <9 months in age) in subjects with inherited EB (subtypes DEB, JEB, or Kindler EB) within 45 days of treatment with Oleogel-S10 compared to control gel based on clinical assessment by the investigator (the wound was rated as "closed" at first appearance of complete re-epithelialization without drainage).

    Measured: 45±7 days

Secondary outcomes (7)
  1. Time to First Complete Closure of the EB Target Wound as Evidenced by Clinical Assessment Until Day 90 (D90) or End of Double-blind Phase (EDBP)

    The first key secondary endpoint was time to first complete closure of the EB target wound as evidenced by clinical assessment within 90 days or by EDBP, using a nonstratified log-rank test.

    If the primary analysis of the primary efficacy endpoint showed superiority at the 5% significance level, hierarchical confirmatory testing of the 6 key secondary endpoints was to be performed.

    Measured: 90±7 days

  2. Proportion of Patients With First Complete Closure of the EB Target Wound at D90 or EDBP Based on Clinical Assessment by the Investigator Until D90 or EDBP

    The second key secondary endpoint was the proportion of subjects with first complete closure of the EB target wound within 90 days of treatment or by EDBP based on clinical assessment by the investigator.

    Measured: 90±7 days

  3. The Incidence of EB Target Wound Infection Between Baseline (DBP D0) and D90 or EDBP as Evidenced by Adverse Events (AEs) and/or Use of Topical and/or Systemic Antibiotics (Related to Wound Infection)

    The incidence of EB target wound infections between Baseline (DBP D0) and D90 or EDBP was assessed based on the total number of patients with an EB target wound infection, as evidenced by AEs and/or the use of topical and/or systemic antibiotics, and the total number of patients

    Measured: 90±7 days

  4. The Maximum Severity of EB Target Wound Infection Between Baseline (DBP D0) and D90 or EDBP as Evidenced by AEs

    Target wound infections between baseline (DBP D0) and D90 or EDBP were assessed for maximum severity (maximum severity was evaluated if a subject had a wound infection event evidenced by AEs). [Note: Here, 1 event less is recorded in the control gel group as for the previous secondary outcome measure, because only wound infections that were reported as AEs could be assessed for severity and were included in this analysis.]

    Measured: 90±7 days

  5. Change From Baseline (DBP D0) in Total Body Wound Burden as Evidenced by Clinical Assessment Using Section I (Assessment of the Skin Except for the Anogenital Region) of the 'EB Disease Activity and Scarring Index' (EBDASI), at D90 or EDBP

    The evaluation of total body wound burden (TBWB) was based on clinical assessment using Section I (Skin) of the Epidermolysis Bullosa Disease Activity and Scarring Index (EBDASI). The EBDASI skin activity (blistering/erosions/crusting) was scored from 0 to 10 for each of 10 anatomical locations (excluding the anogenital and buttocks regions). Therefore, the total skin activity score (i.e., TBWB) could range from 0 to 100, with lower scores indicative of less wound burden. The change in TBWB was assessed from baseline (DBP D0) to D90 or EDBP.

    Measured: 90±7 days

  6. Change From Baseline (DBP D0) in Itching Using the 'Itch Man Scale' in Patients ≥ 4 Years and up to 13 Years of Age Before Wound Dressing Changes at D90 or EDBP

    Change from Baseline at D90 or EDBP on the Itch Man Scale in patients 4-13 years of age. The scale runs from 0 (comfortable, no itch) to 4 (itches most terribly, impossible to sit still, concentrate).

    Measured: 90±7 days

  7. Change From Baseline (DBP D0) in Itching Using the 'Leuven Itch Scale' in Patients ≥ 14 Years of Age Before Wound Dressing Changes at D90 or End of Double Blind Phase (EDBP)

    Change in Leuven Itch Scale (patients ≥ 14 years of age) scores taken from two time points, Baseline and Day 90±7 [End of Double Blind Phase (EDBP)]. The Leuven Itch Scale measures six dimensions of the itch experience: Frequency Subscore (0 = Never to 100 = Always); Duration Subscore (0 = Between 0 and 30 minutes to 100 = More than 2 hours); Severity Subscore (0 = No itch to 100 = Worst possible itch); Consequences Subscore [0 = Never to 100 = Always (lower score indicates less negative consequences from the itch)]; Distress Subscore (0 = Not distressing at all to 100 = Very distressing); Surface Area Subscore (0-100, high values indicate more parts of the body are itching)

    Measured: 90±7 days
