New gel made from platelets shows promise for healing diabetic foot sores
NCT ID NCT06319287
First seen Jun 27, 2026 · Last updated Jul 21, 2026 · Updated 2 times
Summary
This study tested a gel called PEP-TISSEEL, made from platelet-derived particles and a natural sealant, on diabetic foot ulcers. 59 adults with type 1 or 2 diabetes and shallow foot sores were treated for 12 weeks. The goal was to see if the gel helps wounds close safely and faster than standard care.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- PEP-TISSEEL (a gel made from platelet-derived exosomes mixed with a fibrin sealant)
- What this could lead to
- If successful, this could offer a new topical treatment to help heal diabetic foot ulcers faster and reduce complications.
- What could go wrong
- This is an early Phase 2a trial with only 59 participants, so results may not apply widely. The treatment is applied topically, but risks like infection or poor healing remain.

Inclusion Criteria: 1. Males and females ≥ 18 years of age 2. Properly obtained written informed consent 3. Documented history of Type I or Type II Diabetes Mellitus, requiring oral and/or insulin replacement therapy 4. The index ulcer is classified as Wagner grade 1 ulcer and remains Wagner 1 Grade between Screening and Randomization/Baseline visit (Visit 1 through Visit 3) 5. These ulcers are superficial, full-thickness ulcers limited to the dermis, not extending to the subcutaneous tissue 6. Area of index ulcer must be between 1 cm2 to 15 cm2 post debridement at screening and baseline 7. The index ulcer must be located anatomically on the foot with ≥ 50% of the wound area below the medial or lateral malleolus 8. Presence of a persistent nonhealing DFU for at least 4 weeks from Randomization and not more than 1 year that has failed to respond to SOC at any point during this timeframe 9. Adequate vascular perfusion as evidenced by one of the following: 1. Dorsal transcutaneous oxygen measurement (TCOM/TcPO2) measurement of ≥ 40 mmHg within 90 days of Screening (Visit 1 or 2) 2. Ankle Branchial Index (ABI) between 0.7 and 1.3 within 90 days of Screening (Visit 1 or 2) using the extremity on which the index ulcer is located 3. Arterial Doppler ultrasound evaluating for biphasic or triphasic dorsalis pedis and/or posterior tibial vessels at the level of the ankle or a TBI (Toe Brachial Index) of \> 0.6 is acceptable within 90 days of Screening (Visit 1 or 2) 10. The index ulcer has been offloaded with protocol defined offloading device during Screening (Run-In) period through Randomization/Baseline visit. 11. Must meet one of the following criteria: a. Female subjects of Non-Child-Bearing Potential defined as: i. Postmenopausal for at least 1 year (Subject verbal confirmation acceptable), or surgically sterilized (i.e., hysterectomy or bilateral oophorectomy more than 3 months prior to Screening (Visit 1 or 2)), or ii. Bilateral tubal ligation more than 6 months prior to Screening (Visit 1 or 2), or iii. Must have a negative serum β-hCG pregnancy test at Visit 1 and not be breastfeeding prior to being administered with the study drug b. Male subjects of Non-Childbearing Potential are defined as those vasectomized subjects whose vasectomy was performed 6 months prior to Screening (Visit 1 or 2) or those diagnosed as sterile by a physician c. Females and Males of Childbearing Potential who practice an acceptable method of contraception defined as the use of any form of hormonal contraceptive, a barrier method with spermicide, condoms, intrauterine device, or abstinence from sexual intercourse starting at least 60 days prior to Screening and continuing at least 30 days following the last treatment. Female will undergo a negative serum β-hCG pregnancy test at Visit 1 and an additional urine test at Baseline/Randomization (Visit 3 or Day 0) and must not be breastfeeding prior to being administered with the study drug 12. Ability to comply with the study protocol as per investigator discretion Exclusion Criteria: 1. Actively undergoing chemotherapy treatment (localized radiation treatment is allowed if it is not on the DFU wound site and in remission based on scans, bloodwork or some other kind of test, such as a breast biopsy or a bone marrow biopsy) 2. Ulceration with exposed tendon, capsule, or bone 3. Suspicion of bone or joint infection by clinical or other criteria as per STONEES criteria below: a. STONEES criteria for infection: i. size increase, ii. temperature elevation, iii. os (probe to bone) iv. new areas of breakdown v. exudative vi. erythema/edema vii. smell 4. Unable or unwilling to utilize the protocol defined offloading device 5. Subjects who have undergone endovascular or open revascularization of the index limb within the last 30 days from Screening. 6. Index ulcer has decreased in area by ≥ 30% between Screening (Visit 1) and Baseline visits 7. Any subject that is currently on/or requires oral, systemic or topical antibiotics, or is anticipated to require their use during the course of the study 8. Any subject that has vascular compromise requiring surgical intervention or has undergone vascular reconstruction or angioplasty less than 1 month prior to randomization. Any planned surgical procedures during the study participation 9. Serum Creatinine level \> 3.0 mg/dL 10. Hemoglobin A1c (HbA1c) \>12% 11. Aspartate Aminotransferase (AST, GOT) and/or Alanine Aminotransferase (ALT, GPT) \>3x the upper limit of normal 12. Acute active Charcot foot 13. The location of the index ulcer is within 2 cm of any other ulcer 14. Any subject that would be unable to safely monitor the infection status of the index ulcer at home and return for scheduled visits 15. History of immunosuppression or taking immunosuppressive agents including systemic corticosteroids, except stable daily doses of 5 mg/day or less for chronic conditions for up to 5 days 16. Any subject with a life expectancy ≤ 6 months 17. Pregnancy, including a positive pregnancy test at Baseline, or lactation/breastfeeding at anytime 18. Use of investigational drugs or biologics within 28 days prior to screening (Visit 1 or 2) 19. History of a concurrent condition that, in the Investigator's opinion, would jeopardize the safety of the subject or compliance with the protocol 20. Known or suspected active abuse of alcohol, or non-prescription drugs 21. Participation in another interventional clinical study or study in the past 30 days of Screening (Visit 1 or 2) or concurrent participation in another interventional clinical study 22. Subjects who have untreated Hep C 23. Subjects who are HIV positive 24. Subjects on anticoagulation that are not maintained within the International Normalized Ratio (INR) of \> 3.0
