E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
to assess whether ixekizumab every 2 weeks (Q2W) is superior to placebo at Week 12 in the treatment of patients > 6 years of age with EBS-gen sev in improving their QoL |
|
E.2.2 | Secondary objectives of the trial |
-To assess the safety of ixekizumab treatment in EBS-gen sev treated patients
-To compare the efficacy and health outcomes measures evolution between ixekizumab Q2W and placebo at Week 12 in term of severity, itch, pain and duration of dressing
-To compare the efficacy and health outcomes measures evolution between ixekizumab Q2W and placebo between S12 and S20
|
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
- Male or female patients 6 years or older
- Laboratory confirmed diagnosis of EBS-gen sev due to KRT5 or 14 mutation
- DLQI or cDLQI ≥ 10
- Subject/caregiver agrees not to use any topical therapies other than the investigator approved
|
|
E.4 | Principal exclusion criteria |
- EBS lesions requiring oral therapy to treat an infection
- Use of any diacerein containing product within 6 months prior to Visit 1
- Use of systemic immunotherapy or cytotoxic chemotherapy within 60 days prior to Visit
- Use of systemic steroidal therapy within 30 days prior to Visit 1
- Use of any systemic product that, in the opinion of the investigator, might put the subject at undue risk by study participation or interferes with the study assessments within 30 days prior to Visit 1

E.5 End points |
E.5.1 | Primary end point(s) |
proportion of patients achieving ≥ 75% of diminution of the dermatologic QoL (DLQI and cDLQI) at week 12 compared to baseline |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
- Safety and tolerability will be assessed through the description of specific events occurring during the study
- Secondary efficacy and health outcomes measures
- Severity of EB will be assessed using the validated score iscorEB, the static - Physician Global Assessment (sPGA) and the patient global assessment (PaGA)
- Itch will be assessed using a visual analogic scale (VAS).
- Pain will be assessed using a VAS
- The duration of dressing will be evaluated by patients/parents on the week before visit
- The QoL and the efficacy and health outcomes measures during the follow-up post-treatment period (S12-S20) will be defined as for the treatment period
