New gel could speed healing of chronic wounds
NCT ID NCT07406152
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests a gel called ZKARE® for treating chronic ulcers that won't heal on their own. About 134 people with pressure sores, diabetic foot ulcers, or leg ulcers will either get the gel plus standard care, or standard care alone. The goal is to see if the gel helps wounds heal better and faster, and if it's safe to use.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ZKARE® gel (a topical polymeric gel dressing)
- What this could lead to
- If successful, this gel could become a new option to help heal stubborn chronic ulcers faster and more effectively.
- What could go wrong
- This is an early-stage trial with only 134 participants, so results may not apply to everyone. The gel is a device, not a drug, so its effect may be modest.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Adult patients (≥18 years). * Presence of at least one chronic hard-to-heal ulcer, including any of the following etiologies: Grade II, III or IV pressure ulcers; neuropathic diabetic foot ulcers (grade I, II or III), Wagner Grade I-III or Texas 0, I, II, III / Stage B; class C6/C6r venous leg ulcers measured with CEAP scale ; neuro-ischaemic ulcers with adequate distal perfusion (ABI/ITB ≥ 0.7-0.89; mild PAD); mixed-etiology venous ulcers and any chronic lower-limb lesion with palpable distal pulses. * Ulcer size between 1 cm² and 100 cm². * Ability and willingness to comply with all study visits and procedures according to the clinical protocol. * Ability to understand and sign the informed consent, obtained before performing any protocol-specific procedures. Exclusion Criteria: * Ulcers of etiologies not listed in the inclusion criteria. * Ischaemic, neoplastic or atypical ulcers. * Severe comorbidities judged to compromise safety or study compliance, including: severe malnutrition, palliative/terminal status, severe anemia, decompensated heart failure, chronic kidney disease stage III/IV or in dialysis. * Ulcers with moderate-severe or severe infection per PEDIS-IDSA infection grading scale. * Known allergy or sensitivity to any component of the investigational product. * Any condition that, in the investigator's opinion, may compromise patient safety or adherence to the protocol. * Pregnancy or planned breastfeeding.
