About
This is a three-part, Phase I, first-in-human study designed to evaluate the safety, tolerability, and potential systemic exposure of multiple topical doses of TCP-25. Part I includes healthy volunteers with acute epidermal wounds formed by the suction blister technique. Part II includes patients with non-healing leg ulcers and Part III patients with dystrophic epidermolysis bullosa (DEB).

Inclusion and exclusion criteria
Part I:
Inclusion Criteria:
Willing and able to give written informed consent for participation in the study.
Healthy male or female subject 18-60 years (inclusive) of age at the time of signing the informed consent.
Body Mass Index (BMI) ≥ 18.0 and ≤ 30.0 kg/m2.
Healthy and intact skin where the blister suction wounds will be induced.
Women of childbearing potential (WOCBP) must have a documented negative serum pregnancy test done at the screening visit, within 4 weeks prior to suction blister formation and the start of study treatment.
WOCBP must practice abstinence (only allowed when this is the preferred and usual lifestyle of the subject) or must agree to use a highly effective method of contraception with a failure rate of < 1% to prevent pregnancy (combined [oestrogen and progestogen containing] hormonal contraception associated with inhibition of ovulation [oral, intravaginal, transdermal], progestogen-only hormonal contraception associated with inhibition of ovulation [oral, injectable, implantable], intrauterine device [IUD] or intrauterine hormone-releasing system [IUS]) from at least 4 weeks prior to dose to 4 weeks after last dose. Female subjects must refrain from donating eggs from the date of dosing until 3 months after dosing with the IMP. Their male partner must agree to use a condom during the same time frame if he has not undergone vasectomy.
Women of non-childbearing potential are defined as pre-menopausal females who are sterilised (tubal ligation or permanent bilateral occlusion of fallopian tubes); or females who have undergone hysterectomy or bilateral oophorectomy; or post-menopausal defined as 12 months of amenorrhea (in questionable cases a blood sample with detection of follicle stimulating hormone [FSH] 25-140 IE/L is confirmatory).
Male subjects must be willing to use condom or be vasectomised or practice sexual abstinence to prevent pregnancy and drug exposure of a partner and refrain from donating sperm from the date of last dosing until 3 months after the last dosing with the IMP. Their female partner of child-bearing potential must use contraceptive methods with a failure rate of < 1% to prevent pregnancy (see above).

Exclusion Criteria:
History of any clinically significant disease or disorder which, in the opinion of the Investigator, may either put the subject at risk because of participation in the study, or influence the results or the subject's ability to participate in the study.
