LUT017 Gel for Venous Leg Ulcers and Chronic Non-Healing Skin Wounds in Adults

Starting soon · Phase 1

Conditions studied: Venous Leg Ulcer, Chronic Non-Healing Cutaneous Wounds, VLU

In brief

This research study is investigating a new topical medication called LUT017, which is being developed to help heal chronic skin wounds, particularly those known as venous leg ulcers (VLUs). VLUs are open sores that commonly occur on the lower legs due to poor blood flow in the veins. These wounds can be painful, slow to heal, and difficult to treat, especially in older adults and people with conditions like diabetes or obesity. LUT017 is a gel that will be applied directly to the surface of these wounds. The goal of the study is to find out if the gel is safe and well tolerated when applied once a week for up to 8 weeks. The researchers will also look for early signs of whether the gel helps the wounds heal more quickly or completely. The gel contains a medicine that has been shown in animal studies to activate natural skin repair processes and promote cell growth, potentially speeding up the healing process. The study will involve between 12 and 18 adult participants who have had a chronic leg wound for at least 4 weeks. All participants will go through a screening process to make sure they are eligible. If they qualify, they will first complete a two-week "run-in" phase where their wound will be treated with standard medical bandages. This phase helps ensure that only participants whose wounds are not healing with normal care are included. If participants remain eligible after this period, they will start the treatment phase. During this phase, they will come to the clinic once a week for 8 weeks to receive the LUT017 gel treatment directly on their wound. Each visit will include a physical exam, vital signs, wound evaluation, photographs of the wound, and blood tests to monitor safety. After the 8-week treatment period, participants will return for two follow-up visits-one at 3 months and one at 6 months after their first treatment. These visits will help the researchers understand how long any benefits of the treatment might last and monitor for any delayed side effects. In total, participants will be involved in the study for about 6.5 months and will have approximately 12 to 14 visits to the clinic. Participation is entirely voluntary, and individuals can withdraw at any time. The research team is committed to ensuring participant safety and privacy throughout the study.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Subjects with venous leg ulcers (VLU), defined by open skin lesion of the leg as a result of venous hypertension.
• Subject must be ≥ 18 years of age.
• Active lower extremity ulceration (CEAP classification of C6).
• Non-healing VLU ≥ 4 weeks but not greater than 24 months.
• Ulcer size ≥ 2cm2 ≤ 20cm2.
• a. Target ulcer will be defined as the largest ulcer on the affected limb. Only one wound per subject will be designated as the study wound and treated with the investigational gel. If a subject has two wounds separated by less than 1 cm of intact skin, these wounds will be considered a single study wound, and the surface areas of both wounds will be added together for eligibility purposes; if the combined area exceeds 20 cm², the subject will be excluded from the study. Although only one wound will be directly treated, local activation of the MAPK pathway may result in biological stimulation of the adjacent untreated wound when wounds are separated by less than 1 cm.
• Chronic venous insufficiency confirmed by ultrasound within previous 12 months.
• Adequate perfusion confirmed within the past 12 months.:
• Dorsalis Pedis (DP) or Posterior Tibial (PT) systolic pressure ≥ 60mmHg on the study limb.
• Transcutaneous partial pressure oxygen (TcP02) > 30mmHg.
• Great toe systolic pressure > 40mmHg.
• Must be able and willing to provide informed consent prior to study participation.
• Female subjects of childbearing potential must have a negative serum pregnancy test at Screening and a negative urine pregnancy test at baseline (Day 0). They should agree to use highly effective methods of birth control, defined as those with failure less than 1%, such as implants, injectables, combined oral contraceptives, some intrauterine contraceptive devices (IUD's), sexual abstinence, or a vasectomized partner. Such subjects should agree to have monthly pregnancy test documented.

You may not qualify if…

• Target ulcer has exposed of tendon, muscle, or bone.
• Target ulcer is of non-venous etiology.
• Target ulcer has been treated with living cellular therapy within 4 weeks of the randomization.
• Target ulcer shows any signs of infection (only non-infected ulcers are eligible).
• Patient has undergone endovenous ablation or other venous surgery within 4 weeks of enrollment.
• Unable to tolerate multi-layer bandages or compression garments.
• Decompensated congestive heart failure within 4 weeks of screening.
• Active soft tissue or bone infection requiring antibiotics.
• Skin cancer on the target limb within the last 24 months.
• Actively receiving chemotherapy and/or radiation therapy for cancer.
• Treatment with a serine/threonine-protein kinase BRAF inhibitor, including but not limited to Zelboraf® (vemurafenib), Tafinlar® (dabrafenib), BraftoviTM (encorafenib) or Nexavar® (sorafenib), within 30 days or 5 half-lives of the drug prior to Screening, whichever is longer.
• Blood chemistry or counts values as follows:
• White Blood Cells (WBC)< 1.5 x 109/L.
• Absolute < 0.9 x 109/L.
• Platelet count < 50 x 109/L.
• Alanine aminotransferase > 3 x upper limit of normal.
• Aspartate aminotransferase > 3 x upper limit of normal.
• Serum albumin <2.0 g/dL.
• HbA1c value of > 12% within the past three (3) months.
• Current use of systemic corticosteroids > 5 mg daily or equivalent within 4 weeks.
• Currently pregnant or trying to become pregnant.
• Inability or unwillingness to participate in all aspects of study protocol or as determined by the Investigator.
• Known hypersensitivity to the ingredients of the study drug.
