Eligibility Criteria:
Inclusion Criteria:~1. Patients who diagnosed with recessive dystrophic epidermolysis bullosa through clinical, histological(Partial or complete loss of VII collagen (C7) should be confirmed by DIF and electron microscopy examination) and genetic testing(COL7A1 Genetic mutation must be confirmed).~2. RDEB patients aged 10 to 60 years old (In the case of patients under the age of 19, patients who obtain consent from a representative (parental authority or guardian))~3. Patients who have heard the purpose and contents of a clinical trial and voluntarily signed the consent form prior to the clinical trial (Legal representative in case of minor)~4.

Clinically significant infections within four weeks of the screening date or during the screening period (pneumonia, pyelonephritis, Clostridium difficile etc)~7. All kinds of confirmed congenital or acquired immunodeficiency syndrome~8. Acute, chronic infection (Type B, Type C) corresponding to:~   - HBs-Ag, IgM anti-HBc, IgG anti-HBc positive (However, if HBs-Ag and IgM anti-HBc is negative, but only IgG anti-HBc is positive, if ani-HBs Ab positive, this clinical trial can be registered.)~9. Patients who with allogenic stem cell treatment experience within 1 year from the screening test date~10.

Type VII collagen ELISA positive and IIF positive~12. Pregnant or lactating women (Women of childbearing potential should agree to use appropriate contraceptive methods (hormonal or barrier method of contraception or abstinence) prior to enrollment in the study and during the study period, including one month after the last administration of the test drug. If pregnant or suspected of being pregnant while participating in the study, the investigator should be informed immediately.)~13.
