E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Efficacy of octenisept® compared to NaCl solution and antimicrobial effect in chronic wounds. Decrease of bacterial load after 14 days of treatment will be used as a parameter for efficacy. Bacterial count will be defined with a semi-quantitative bacterial swab. |
|
E.2.2 | Secondary objectives of the trial |
- To assess subjective tolerance of octenisept® using the PBI and FLQA questionnaire - To evaluate the wound healing time and wound size - Development of bacterial load at the follow-up visit |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
- Male and female patients of at least 18 years at the time of consent - Females of non-childbearing potential (postmenopausal ≥ 50 years old and amenorrhea ≥ 12 month after break of exoge-nous hormones or ≤ 50 years old, documented FSH – and LH level equal to the postmenopausal range and amenor-rhea ≥ 12 after break of all exogenous hormones) - Females of non-childbearing potential due to postoperative bilateral tubal ligation, bilateral salpingectomy, bilateral oo-phorectomile or hysterectomy - Patients with a venous leg ulcer (Ulcus cruris) - Patients with a chronic leg ulcer - Duration of the target venous ulcer ≥ 4 weeks - Surface area of the target venous ulcer (after debridement) ≥ 1 - Patients with a chronic leg ulcer with bacterial load suspected in at least one of the following bacterial species: o Staphylococcus aureus o Streptococcus pyogenes o Enterococcus spp. o Escherichia coli o Proteus mirabilis o Pseudomonas aeruginosa - Satisfactory medical assessment with no clinically significant or relevant abnormalities as determined by medical history, physical examination, clinical [vital signs, 12-lead electro-cardiogram (ECG)], and clinical laboratory evaluation (hematology, biochemistry, urinalysis) as assessed by the In-vestigator - Ability to provide written informed consent - Signed declaration of consent - Willingness to cooperate
|
|
E.4 | Principal exclusion criteria |
- Females of childbearing potential - Known history of alcohol or drug abuse - Patients with a serious concomitant disease (serious coronary heart disease, serious heart failure (NYHA III or IV), serious nephrotic - or hepatic dysfunction, malign disease, dementia) will be excluded if the investigator decides that study inclusion is not recommended. - Known history of allergic reactions attributed to octenisept® or one of its compounds - Participation in another clinical trial within the last 30 days before randomization - Contraindication regarding local wound therapy with local antimicrobial agents (e.g. inflamma-tion requiring systemic antibiotic therapy, malignant ulcer) - Planned ulcer treatment within the treatment period after Visit 1 e.g. surgery on varicose veins (laser coagulation, sclerotherapy, stripping), skin grafting, application of cultured keratino-cytes, bioengineered tissue, biophysical modalities - Not permitted therapy within the last 7 days prior to the first dose: • use of any systemic antibiotics • local antimicrobial agents and topical steroid treatment of the target ulcer (these drugs confound the efficacy of the investigational drug) - Concomitant treatment with other preparations that interfere with the trial preparation or the disease - Absence of declaration of consent - Doubt about willingness to cooperate - Non-fulfillment of the inclusion criteria - Staff of the study centre, the investigator him/herself or close relatives of the investigators |
|
