简要总结
Dose-response relationship study of S42909 on leg ulcer healing after oral repeated administration in patients with active venous leg ulcer.
详细描述
S42909 is an inhibitor of β-Nicotinamide Adenine Dinucleotide Phosphate (NADPH) oxidase which also inhibits vascular leukocyte adhesion to endothelial cells, Matrix Metalloproteinase-2 (MMP-2) and Plasminogen Activator Inhibitor-1 (PAI-1) activity. It is proposed for development in the treatment of venous and mixed leg ulcers.
This proof of concept study is a randomized, double-blind, placebo-controlled, multicenter, Phase IIa trial to evaluate the dose response of S42909 for the treatment of venous leg ulcers.
Patients suffering from chronic venous disease and having at least one active venous leg ulcer will be selected at the selection visit (ASSE). One Reference Ulcer (RU) defined as the largest ulcer in size that is fitting the area selection criteria will be established. At ASSE, a first picture will be taken before cleansing and debridement and a second picture will be taken after cleansing and debridement. The investigator will check that the selection RU area is compliant with the selection criteria. Patients will start the selection period and will be switched from their current pharmacological and/or local treatment (if any) for venous leg ulcer to local wound care with sterile saline solution or sterile water, "non-active" dressings and standardized compression (same strength and type of compression). They will be administrated the placebo selection treatment for a period of fourteen days.
Three (or four) working days before the inclusion visit, the participants will come to the site for a RU picture in order to get the RU area central measurement for inclusion visit (W000).
At W000, the investigator will check that the inclusion RU area is compliant with the inclusion criteria. The investigator will also check that the participant is compliant with the selection treatment and stockings wearing.

入选标准
- •Caucasian (defined for this study as having 2 Caucasian parents), men or women
- •Age ≥ 18 years old
- •18.5 kg/m2 ≤ BMI ≤ 45.0 kg/m2 (= Weight (kg) / height² (m²))
- •Patients with chronic venous disease documented by imaging to detect a venous disorder in one or both the sub- and extra-fascial venous systems. The examination performed within 6 months before selection can be used.
- •Patients with at least one active venous leg ulcer localised in the gaiter area (CEAP C6) diagnosed or reoccurred for more than 6 weeks and less than 2 years at selection and 3 cm away from other ulcers. Patients with bilateral ulcerations or multiple ulcerations on one or both legs are eligible for selection.
- •Size of Reference Ulcer (defined as the largest ulcer in size that is fitting the area selection criteria) should be ≥ 5 cm2 and ≤ 100 cm2 at the selection visit and ≥ 4.5 cm2 and ≤ 100 cm2 at the inclusion visit (measured by transparent sheet and confirmed with the digital 3D imaging device).
- •Ankle Brachial Pressure Index (ABPI) ≥ 0.8 and ≤ 1.3 measured by Doppler ultrasound.
排除标准
- •Unlikely or unwilling to be compliant to standardized compression recommendation, study medication and visits, previous records of poor compliance to compression stockings.
- •Inadequately controlled type 1 and type 2 diabetes with an HbA1c > 8%.
