Please assess the completion status of the following clinical trial:

Trial Title: A Double-blind, Randomized, Intra-subject Placebo-controlled, Multicenter, Multiple Dose Study, Evaluating Safety, Proof of Mechanism, Preliminary Efficacy and Systemic Exposure in Subjects With Confirmed DDEB or RDEB Diagnosis With One or More Pathogenic Mutations in Exon 73 in the COL7A1 Gene

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: QUADRUPLE
- Phase: PHASE1/PHASE2
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~1. Male or female, ≥ 4 years of age at Screening with a clinical diagnosis of DDEB or RDEB and at least one pathogenic mutation in exon 73 of the COL7A1 gene.~2. Have at least one TWA, ie, a skin area of 7 x 7 cm that ishows no signs of local infection, and contains a target wound that is either new or shows dynamic wound healing and complies to the following additional criteria:~   1. surface area of the target wound ranging from 5 to 30 cm2, located centrally in the selected 7 x 7 cm TWA.~  2. exposed sub-epidermal tissue to allow absorption of the IMP.~  3. no suspicion of current squamous cell carcinoma (SCC) upon visual inspection.~Exclusion Criteria:~1. Pregnant or breast-feeding female~2. Hemoglobin level at Screening requiring transfusion. The subject may be rescreened when the condition is considered stable.~3. Use of aminoglycosides, by any route of administration, except eye drops, 7 days or 5 half-lives, whichever is longer, prior to Baseline visit.~4. Untreated carcinoma of the TWA or history of carcinoma within 5 years prior to Screening, except adequately treated cutaneous squamous or basal cell carcinoma.~5. Life expectancy less than 6 months, as assessed by the Investigator~6. Current or known history of clinically significant hepatic or renal disease, that in the opinion of the Investigator, could impact subject safety or study participation.~7. Treatment with any systemic immunomodulators, immunosuppressants or cytotoxic chemotherapy within 2 months prior to the Baseline visit.~8. Use of any investigational drug or device within 28 days or 5 half-lives of the Baseline visit, whichever is longer, or plans to participate in another study of a drug or device during the study period. The washout of 5 half-lives does not apply to gene and cell therapy.~9. Known hypersensitivity to oligonucleotide treatment or excipients of the IMP.~10. Bleeding disorder or condition requiring the use of anticoagulants to be confirmed by aPTT by local lab within 48 hours of first treatment.~11. Use of systemic or topical steroids within 1 month prior to the baseline visit (inhaled and ophthalmic drops of corticosteroids or low dose topical solution of budesonide for esophagial strictures may be allowed).

- Gender: ALL
- Minimum Age: 4 Years
- Maximum Age: None
- Healthy Volunteers: f

Study Arms:
- First TWA (A) (Type: OTHER): In each subject up to two target wound areas (TWA) are randomized, one each to active treatment or placebo.~In the first arm; randomization of the first selected TWA to active treatment or placebo
- Second TWA (B) (Type: OTHER): In each subject, in the second arm; allocation of the second selected target wound area (TWA) to the alternative treatment. Second arm in the same subject as the first arm.

Based on this trial design, predict the completion outcome and termination type (if applicable).
