Trial design

CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Therapy, Efficacy, Safety

To evaluate the efficacy and safety of EHSG-KF in comparison to meshed STSG in children with partial deep dermal and full-thickness burns.
Primary Objective: to evaluate the efficacy of EHSG-KF in comparison to meshed STSG based on:
- Ratio of covered surface area to biopsy site/donor site surface area 4 weeks post grafting

Secondary objectives 2

  1. % Epithelialization at 3 months post grafting
  2. To evaluate the safety and efficacy of EHSG-KF in comparison to meshed STSG based on the assessment of: - Infection - Scar quality: o Cutometer® 3, 6, 12, 24 and 36 months post grafting o DSM ColorMeter® 3, 6, 12, 24 and 36 months post grafting o POSAS-questionnaire 3, 6, 12, 24 and 36 months post grafting - Graft take at 6-10 days post grafting - % Epithelialization (to estimate ‘time to complete epithelialization’) at 3 and 4 weeks, and 2 and 6 months post grafting - Incidence of wound closure at 4, 8, and 12 weeks post grafting - Growth (% change in surface area, cm2, between 1 and 3 years post grafting) - Assessment and reporting of all observed adverse events - QOL assessment (EQ-5DY and PedsQL) - Healthcare resource utilization (direct and indirect healthcare costs, this questionnaire will not be handed out to patients)

Eligibility criteria

Principal inclusion / exclusion criteria as submitted by sponsor

Inclusion criteria 4

  1. Age: <12 years of age
  2. Deep partial thickness and/or full-thickness burns requiring surgical wound coverage
  3. Expected that ≥90 cm2 of wound (not counting the head and neck area for study patients in The Netherlands) will remain open at 4 weeks post burn despite proceeding with treatment in accordance with the standard of care. >20% TBSA burns can be taken as guideline, but TBSA is not an inclusion criterion.
  4. Signed informed consent from the patient or the parents/legally authorized representative.

Exclusion criteria 12

  1. Patients tested positive for HBV, HCV, syphilis or HIV
  2. Patients with known underlying or concomitant medical conditions that may interfere with normal wound healing (e.g. systemic skin and connective tissue diseases, any kind of congenital defect of metabolism including insulin-dependent diabetes mellitus, Cushing syndrome or disease, scurvy, chronic hypothyroidism, congenital or acquired immunosuppressive condition, chronic renal failure, or chronic hepatic dysfunction (Child-Pugh class B or C), severe malnutrition, or other concomitant illness which, in the opinion of the Investigator, has the potential to significantly delay wound healing)
  3. Severe drug and alcohol abuse
  4. Pre-existing coagulation disorders as defined by INR outside its normal value, PTT >ULN and fibrinogen
  5. Patients with known allergies to amphotericin B, gentamicin, penicillin, streptomycin, or bovine collagen
  6. Previous enrolment of the patient into the current phase II study
  7. Participation of the patient in another study with conflicting endpoints within 30 days preceding and during the present study
  8. Patients or parents/ legally authorized representative expected not to comply with the study protocol (including patients with severe cognitive dysfunction/impairment and severe psychiatric disorders)
  9. Pregnant or breast feeding females
  10. Suspicion of non-accidental injury
  11. Wounds in the head and neck area as study target area (only applicable for study patients in The Netherlands)
  12. Enrolment of the Investigator, his/her family members, employees, and other dependent persons

Endpoints

Primary and secondary outcome measures (English text)

Primary endpoints 1

  1. Efficacy evaluation, as a comparison between the EHSG-KF and control sites, based on: - Ratio of covered surface area to biopsy site/donor site surface area at: - visit 6 (28 ± 3 days post grafting)

Secondary endpoints 6

  1. % Epithelialization at: - visit 8 (90 ± 5 days post grafting)
  2. Safety and efficacy evaluation, as a comparison between the EHSG-KF and control sites, based on: see point 3 - 6
  3. Main secondary safety endpoint: Clinical and microbiologic signs of infection at: o visit 4 (6-10 days post grafting) o visit 5 (21 ± 2 days post grafting)
  4. Main secondary efficacy endpoints: Scar quality at the study areas o Assessment of elasticity of the study areas using the Cutometer® at visit 10 (1 year ± 30 days post grafting) o Assessment of general scar quality at the study areas using the POSAS, a reliable and validated scar assessment tool, at visit 10 (1 year ± 30 days post grafting)
  5. Other secondary safety endpoint: Assessment and reporting of all observed adverse events will be carried out for the full duration of the study from visit 2 on.
  6. Other secondary efficacy endpoint: Epithelialization at: o visit 6 (28 ± 3 days post grafting)
