Inclusion Criteria: 1. Age \>18 years at the time of consent, 2. The patient's psychophysical and legal ability to give informed consent to participate in the study, 3. Signing the informed consent document for participation in the study, 4. Ulcer classified as diabetic foot syndrome (DFS) of neuropathic and/or neuroischemic etiology corresponding to grade IA/IIA and IC/IIC according to the University of Texas classification (Appendix E), 5. Duration of the ulcer not less than 6 weeks, 6. Presence of a wound with an area of 1-25 cm² (after wound debridement), 7. Satisfactory blood supply to the wound area: * assessed using transcutaneous oxygen pressure measurement, if its value is not less than 30 mmHg, * or measurement of systolic blood pressure at the posterior tibial artery and/or dorsalis pedis artery, which is not less than 50 mmHg, to exclude patients who require revascularization therapy, 8. Glycated hemoglobin (HbA1c) \< 11%, 9. General health status of the patient, which in the investigator's opinion allows participation in all study procedures, 10. Use of the wound offloading method recommended by the investigator, 11. Use of effective contraception methods to avoid pregnancy (see also Appendix F) and/or based on the following criteria: * a woman who is unable to have children (after a hysterectomy or bilateral oophorectomy or post-menopause, defined as a period of at least 12 months since the last menstrual period) is exempt from pregnancy tests, * a woman able to have children with a negative pregnancy test result before the administration of the investigational product on the first day and who agrees to periodic pregnancy testing according to the study protocol and to use highly effective contraceptive methods for one month after the end of the active phase of the study (from V6), or two months after the last administration of the investigational drug (from V2). Exclusion Criteria: 1. Etiology of the ulcer other than diabetic foot syndrome, 2. Presence of an active infection in the wound at the time of inclusion in the study, 3. Wound area \<1 cm² or \>25 cm², 4. The patient was enrolled in another clinical trial within the 4 weeks preceding the qualification for this study. 5. Clinically significant limb ischemia: * assessed using transcutaneous oxygen pressure measurement, if its value is lower than 30 mmHg * or measurement of systolic blood pressure at the posterior tibial artery and/or dorsalis pedis artery, if it is lower than 50 mmHg, 6. Presence of an active phase of Charcot joint, 7. Suspected osteitis and/or osteomyelitis within the study wound, 8. Revascularization procedure on the affected lower limb within 3 months prior to study inclusion or planned revascularization procedure, 9. Chronic kidney disease with GFR \< 20 ml/min, 10. Pregnancy and lactation, 11. Allergy to thrombin, 12. Active venous thrombosis, 13. Systemic diseases in the exacerbation stage (acute or decompensated), including heart, kidney, and liver diseases, 14. Active alcohol disease or addiction to psychoactive substances, 15. Allergies to dressing materials used in the study, 16. Oral/intravenous antibiotic therapy at the time of inclusion in the study, 17. Patient undergoing immunosuppressive therapy, including corticosteroid therapy (within 30 days prior to study inclusion), 18. Active cancer or cancer disease in the last 5 years, excluding locally malignant cancers not involving foot tissues, 19. Presence of known clinically active, uncontrolled infections such as hepatitis B, hepatitis C, HIV, and venereal disease (syphilis), 20. Significant features of malnutrition additionally impairing the healing process, regardless of the cause (albumin \< 2.5 g/dl and total protein \< 5 g/dl), 21. Hemoglobin levels \< 9 g/dl, 22. Serum transaminase (alanine and aspartate) activity higher 3x the upper limit of normal (locally).
