Active clinical trials for "Varicose Ulcer"

In this medical trial, a novel prototype of a medical device based on a Cold Atmospheric Air Plasma Jet for the treatment is clinically tested on patients with venous leg ulcers. The device is characterized by producing the first cold air plasma jet compatible with living tissues at a low heat transfer rate with a temperature on the skin surface lower than 40 ºC. It has a practical design to be used by physicians during daily practice with a special focus on unhealed ulcers.

The aim of the study is to assess safety, tolerability and preliminary efficacy of XSTEM-VLU when administered as a single topical dose to patients with difficult-to-heal venous leg ulcers. The study is randomised and the patients will receive either XSTEM-VLU or vehicle as add on to standard wound care. The patients will be followed weekly for 10 weeks after treatment. At 6 months after treatment, the patients will return to the clinic for an end-of-study visit.

This is a multicentre, quasi-experimental study to evaluate the Conformitè Europëenne-marked Compreflex standard calf and foot (with basic liner) under routine conditions. The study will be conducted at 4 clinics and will include 100 consecutive patients. Patients will be followed-up until 26 weeks.

The study evaluates the effects of early endovenous glue ablation on ulcer healing in patients with chronic venous ulceration. Half the patients are randomized to receive early endovenous ablation (within 2 weeks) and a half to standard care

This multicenter randomized controlled trial compares immediate foam sclerotherapy vs. scheduled endovenous treatment in patients with venous ulceration.

Venous ulcers are defined by the presence of open lesions which represent the final stage of chronic venous disease or post-thrombotic syndrome. The risk factors for the development of venous ulcers include age, obesity, female sex, trauma, immobility, factor V mutation, thrombosis, venous agenesis. Recommendation by the current guidelines includes compression and advanced dressing. However, in several cases, they fail to change patients' outcome. The aim of this study is to identify an alternative therapy to treat venous trophic lesions not responding to traditional therapeutic approaches using extracellular vesicles obtained from autologous serum.

Leg ulcers are areas of epidermal discontinuity in lower limbs with causes of venous, arterial, diabetic, pressure, traumatic, allergic, or inflammation. Chronic venous leg ulcers (VLUs) are defined as leg ulcers persisting for 4 weeks or more, a.k.a C6 in CEAP classification of chronic venous insufficiency (CVI) and account for up to 70% of all chronic leg ulcers exhibiting overall prevalence of up to 2% in the general population of western countries with significant morbidity and a negative socioeconomic impact. Wound care, debridement, bed rest with leg elevation, and compression are basic approaches for chronic VLUs. Meanwhile, numerous medical and surgical interventions were developed to promote wound healing and to prevent recurrence by focusing on pathophysiology of chronic VLUs. However, many strategies just have adjuvant effects or exert debatable benefits. The lymphatic system been considered important for removal of excessive fluid from the interstitial space, absorption of fat from the intestine and the immune system, actively involved in regulation of immune cell trafficking and inflammation. Emerging lymphovenous bypass (LVB), a supermicrosurgical technique diverting lymphatic drainage into venous system in dealing with lymphedema, not only restores TH1 and TH2 imbalance, but decreases oxidative stress and increases antioxidant capacity in the serum of lymphedema patients. Clinically, LVB could be an alternative treatment option for patients with lymphorrhea. Based on these facts, the investigators hypothesis that lymphatic hypertension and lymph impregnation contributes chronic venous leg ulcer formation and propose a novel strategy, using LVB to treat patients with refractory/recurrent chronic VLUs. The preliminary results revealed promising results and the investigators would go on clinical trials.

This is a randomized, double-blind, placebo-controlled, phase II, multi-centered study to evaluate the efficacy and safety of ENERGI-F703 GEL in subjects who are ≥ 20 years old with venous leg ulcer (VLU). Subjects will be recruited from multiple sites in Taiwan. The treatment period will be 84 days with another 84-day follow-up period.

Multi-center, prospective,randomized controlled study on the speed of healing, life quality and cost-effectiveness of the treatment with a blue light medical device (EmoLED) versus existing Standards Of Care (SOC) for patients with leg ulcers. The aim of LUCE - "Leg Ulcers Standards of Care Enhancement" clinical trial is to verify the clinical efficacy of a portable battery-powered device blue LEDs based. This study aims to compare the existing SOC (consisting in two visits per week) to a protocol that requires only one visit per week, during which the EmoLED treatment is administered in addition to the current therapy. It is expected to register a difference in efficacy between EmoLED Group and SOC Group, in terms of "healing rate", intended as a reduction of the wound area, but also as a progress, in a broad sense, of the overall clinical situation of the lesion, in terms of pain and quality of life. -Endpoint- The primary endpoint is the comparison of the outcomes in terms of healing rate of lesions treated with SOC (SOC Group) versus lesions treated with EmoLED (EmoLED Group), on week 16th. Patients 80 patients will be recruited (40 patients per group), following these inclusion/exclusion criteria: Inclusion criteria: Subjects suffering from venous and mixed skin ulcers; Presence of a lesion < 100 cm² of area and < 1 cm in depth; Men and women ≥ 18 years old; The patient must be able to understand the aims of the clinical trial and provide informed consent in writing; Chronicity of the lesion: at least 8 weeks. Exclusion criteria: Patients who participated in clinical trials about skin ulcers healing during the previous month; Patients who are not able to understand the aims of the trial; Patients with pressure ulcers; Patients with diabetic foot ulcers; Patients with circumferential leg ulcer (due to the difficulties in analysing the pictures); Patients with clearly infected ulcers or with systemic infection; Patients with ulcers caused by critical ischemia; Patients with a self-harm past that can purposely alter the process of healing; Patients with psychiatric disorders; Pregnancy or breast feeding; Patients with neoplasms or other diseases involving the use of cytostatic or immunosuppressive drugs; Patients with limited lifespan; Patients with photosensitizing illnesses or that take photosensitizing drugs. All inclusion and exclusion criteria must be satisfied before recruitment. Any concomitant phar-macological therapy must be maintained. -Medical and surgical procedures- The lesions will be cleansed with saline solution and, if necessary, surgical debridement will be performed with the most suitable method. At this point, if patient is included in EmoLED Group, the EmoLED treatment starts. After EmoLED application (EmoLED Group) or after cleansing (SOC Group), a polyurethane foam dressing will be applied on the lesion. In case of clinical signs of infection, a silver dressing will be applied. Then an elasto-compressive double layer dressing of the limb with cohesive fixation bielastic la-tex-free bandage will be carried out. The treatment with EmoLED, in addition to the SOC, will be performed during each visit for 60 seconds on each 5 cm diameter sub-area of the selected lesion. In case of multiple lesions matching with both inclusion and exclusion criteria, they will be all treated following the same protocol, depending on the group to which the patient belongs; in this case the Principal Investigator will fill out a data-collection form and take pictures just of the le-sion with the wider area. -Follow up procedure- The patient is called upon to go to the follow-up check after 4 weeks from the healing or, other-wise, from the end of the trial (16 weeks). The follow-up visit will be used to confirm the occurred healing and verify the absence of relapses and/or undesirable effects (if the wound appeared completely healed) or to value the healing progress for the unhealed lesions.

The purpose of the PULSE study are the followingL A.To perform post market clinical follow up (PMCF) on safety and efficacy: Safety: To confirm transient short-terms side effects and verify long-term/outstanding risks. Efficacy: To confirm the performance of PLASOMA, i.e. the beneficial effect on bacterial load. B. Determine the effect of PLASOMA on wound surface area. A secondary purpose is to examine the beneficial effects of PLASOMA on wound healing and to perform a health technology assessment (HTA). This clinical study will be an open label two-armed randomized controlled trial (RCT), performed at at least three sites (multi-center) in the Netherlands. The two arms are: Control group: Standard wound care for 12 weeks or until healing, whichever occurs first; Treatment group: Standard wound care + PLASOMA treatment for 12 weeks or until healing, whichever occurs first. The frequency of PLASOMA treatment will be determined by the treating (para)medical professional based on the number of visits they would schedule for the standard wound care at the study site. For all study subjects, the treatment frequency will be at least once per week (in order to have enough treatments for safety evaluation) and should not exceed once per day. Follow up (FU) will be performed at three timepoints for both arms: FU1: 2 weeks after end treatment period FU2: 12 weeks after end treatment period FU3: 12 months after start treatment.
