Clinical Assessment of Next Science Wound Gels in Healing Below the Knee Amputation Surgical Wound Compared to SOC

This is a prospective, randomized, 90 day, open-label study of patients undergoing below the knee amputation (BKA) with primary closure or completion. Patients who present for BKA with primary closure or completion will have had a pre-op medical evaluation prior to being screened against the protocol's inclusion/exclusion criteria. If criteria are met, patients will be presented with the option to participate in the study and informed consent procedures will be carried out, in compliance with currently applicable participants' rights and safety regulations. A minimum of 64 participants, with up to 70 participants, may be enrolled. A participant requiring bilateral BKA will be excluded. Eligible subjects will need to complete the study to meet the primary endpoint. It is estimated that the study enrollment period will last approximately eighteen months, and the duration of each participants' participation will be three months. Visits in the treatment portion of the study will be carried out at day 0, 3, 14, 21, and 28 days with a scheduling window of 3 days before or after each due date. A phone call follow-up will be conducted at 60 days post-surgery with a window of 7 days before or 14 days after to inquire about the incision (appearance of incision or any noted changes since prior study visit), and overall health of the participant. All participants, regardless of treatment arm, will complete Visit 6 (90 day follow up) with a scheduling window of 7 days before or 21 days after. The key parameters of the study include: percentage of surgical wound area reduction, time patients are deemed ready prosthetic healing, and microorganism type and amounts. Bacterial identification and quantification will occur at days 0, 14, and 28 for all participants.
