Epidermolysis Bullosa Dystrophica
Why
  1. The study's listed conditions name Epidermolysis Bullosa Dystrophica, a narrower term within Epidermolysis Bullosa.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

The study objective is to see if IV Efgartigimod and Vyjuvek treatment in Recessive Dystrophic Epidermolysis Bullosa (RDEB) and IV Efgartigimod treatment in Epidermolysis Bullosa Acquisita (EBA) improves wound healing and affects the levels of C7 antibody levels in serum.

Fewer wounds, more rapidly healing wounds, and decreased C7 antibodies could improve quality of life.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • For DEB patients (aged 12 years or older): DEB confirmed with mutation analysis and correlated by phenotype, and treatment of at least 1 wound treated with topical gene therapy (VYJUVEK). Presence of C7 antibodies above normal cutoff on ELISA.
  • For (classic) EBA patients (aged 18 years or older): EBA confirmed with positive histopathology (DIF), C7 antibodies above normal cutoff on ELISA, and having at least 1 skin lesion.

    1. Male participants:

      - Must agree to use an acceptable method of contraception and not donate sperm from the time that the ICF is signed until they have received their last dose of IMP.

    2. Female participants:

      • Women of must have a negative serum pregnancy test at screening and a negative urine pregnancy test at week 1 / baseline before study intervention can be administered. Subsequent urine pregnancy tests are to be completed at week 6, week 11, week 16, week 21, and week 26 / EoS.
      • WOCBP must agree to use a highly effective or acceptable contraception method until at least 90 days after they receive their last dose of IMP.

Exclusion criteria

Exclusion Criteria:

  • Linear IgA dermatosis-like EBA or other blistering diseases (including but not limited to pemphigus vulgaris, bullous pemphigoid, mucous membrane pemphigoid).
  • Use of the following EBA treatments:

    • sulfasalazine, IVIg, subcutaneous administration of immunoglobulin (SCIg), immunoadsorption or plasma exchange within 2 weeks of the screening visit, tetracyclines with or without nicotinamide at doses higher than the recommended daily allowance (RDA)/dietary reference intake (DRI) within 2 weeks of the screening visit.

    • complementary therapies-such as traditional Chinese medicines, herbs, or procedures (e.g., acupuncture)-within 4 weeks (or 5 half-lives) of the screening visit, if the investigator determines that such therapies may interfere with the study's efficacy assessments and/or potentially risk the safety of the participant.
    • The use of the following EBA treatments is permitted throughout the study: OCS, topical , conventional (e.g., azathioprine, cyclophosphamide, methotrexate, mycophenolate, or mofetil), and dapsone.
  • Moderate to severe renal insufficiency.
  • Known to OCS therapy.
  • uncontrolled active or chronic, bacterial, viral, or fungal infection at screening
  • Medical instability limiting ability to travel to the Investigative Center

  • Subjects actively receiving chemotherapy or immunotherapy at screening
  • Active drug or alcohol addiction as determined by the investigator.
  • Pregnant or nursing women
  • History of unless deemed cured by adequate treatment with no evidence of recurrence for ≥3 years before the first administration of the IMP. Participants with the following cancers can be included at any time, provided they are adequately treated prior to screening:

    1. Basal cell or squamous cell skin cancer
    2. Carcinoma in situ of the cervix
    3. Carcinoma in situ of the breast
    4. Incidental histological finding of prostate cancer (TNM stage T1a or T1b)
Terms in these criteria, in plain language(9)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Karnofsky performance status (KPS)

A 0–100 scale of how well someone can carry out everyday activities. 100 is no complaints and no signs of illness; 70 is able to look after yourself but not to work or keep up normal activity; 50 is needing considerable help and frequent medical care.

Studies often ask for 60 or 70 and above. Your doctor gives the score.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Study arms

  • Experimental
    Efgartigimod

    There is one arm of the study. First, each participant undergoes a 3-month observational period. If the participant has DEB, they will continue their standard of care VYJUVEK as prescribed. After the observational period concludes, the participant enters the treatment period, during which Efgartigimod is administered. DEB participants will continue their standard of care VYJUVEK as prescribed.

    Biological: Efgartigimod

Interventions

What researchers measure

Primary outcomes

  1. Reduction in serum C7 antibody levels

    The proportion of patients who exhibit reduction in serum C7 antibody levels at week 26 as compared to week 1.

    Time frame: 26 weeks

  2. Adverse Events and Effects

    Occurrence of adverse events and effects.

    Time frame: 38 weeks

  3. The Epidermolysis Bullosa Disease Activity and Scarring Index (EBDASI) improvement

    The overall improvement of EB symptoms at week 26 as compared to week 1, measured by percentage change of a participant's EBDASI score (overall total score, total activity score, and total damage score). The EBDASI is scored in the range of 0 - 506, with a lower score corresponding to mild disease and higher score corresponding to more severe disease.

    Time frame: 26 weeks

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 5, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
