Processed Amniotic Fluid (pAF) for the Treatment of Chronic Wounds

Phase 1

Terminated

Interventions: Drug: Processed Amniotic Fluid
Other: Standard of Care Wound Treatment Regimen

Brief Summary: A prospective randomized controlled study to determine the safety and feasibility of using processed amniotic fluid (pAF) to expedite healing in chronic wounds.

Detailed Description: The goal of our study is to assess, in an outpatient setting, the safety and the time to wound closure in chronic wounds treated with processed amniotic fluid (pAF). We will include patients with lower extremity full thickness wounds that are greater than 3 months old and less than 12 months old. The wound size must be greater than 5cm2 and less than 75 cm2. We will exclude anyone that requires skin grafting, or wounds with sinus tracts. Our primary objective is to determine the safety and feasibility of using pAF to treat patients with chronic wounds. The secondary objective is to determine the efficacy of pAF compared to standard of care in reducing wound area.

Recruitment & Eligibility

Patient who is able to complete required site study visits and procedures in good faith

Exclusion Criteria

Suspicion of or diagnosis of osteomyelitis underlying the wound.
Patients who have received an investigational agent or intervention within the prior 30 days or plan to use within the study period.
Patient with sinus tracts, enterocutaneous fistulas or other epithelialized tracts.
Patients who require skin grafting.
Patients diagnosed with a highly disruptive, non-controlled mental health disorder (e.g.., bipolar, or schizophrenia.
Patients with a history of prior drug abuse.

Arm && Interventions

Group	Intervention	Description
Amniotic Fluid Injection	Processed Amniotic Fluid	Processed Amniotic Fluid. Dose is 1ml/5cm2; Route: injected directly into wound; Limited to two injections. The wound will then be dressed according to standard of care.
Standard of Care Wound Treatment Regimen	Standard of Care Wound Treatment Regimen	Primary dressings are variable and based on the moisture content and microorganism load. In general, wounds respond differently to various topical treatments. Through our clinical practice, we have found that wounds plateau with the same topical for greater than 4 weeks, hence changing antimicrobial topical helps to manage the bacterial overgrowth. We will start with our application of our slurry, a 1:1:1 ratio of Nystatin ointment, Mupirocin Ointment, and Bacitracin Ointment. This slurry will be applied directly to the cleansed wound, followed by silver gauze/foam product to all wounds. Types of silver product- site and comfort predict use of Restore, Mepilex-AG, or Mepitel-AG. If allergies to the above slurry occurs, we will use medical honey with or without bacitracin. If ointment related rash present with transition to silver product only or silver product plus medical honey.

Primary Outcome Measures

Name	Time	Method
Safety - Adverse Events Including Serious Adverse Events	Approximately 7 months after enrollment	Safety and tolerability will be evaluated by the PI from the results of reported signs and symptoms and scheduled physical examinations. The primary endpoint is whether the patient experienced any post-randomization, study-related serious adverse event (SAEs) while on study (collections of new AEs begins at visit two and ends at visit five which is approximately, 7 months after enrollment). An SAE is considered study-related if the medical monitor concludes the SAE is either possibly related or probably related to study participation. Although unresolved SAE's were to be monitored for 1 year or until resolution, no SAEs were unresolved at the time of study completion (approximately, 7 months after enrollment).

Secondary Outcome Measures

Name	Time	Method
Feasibility - Reduction in Wound Size - Secondary Outcome Per Secondary Assessor	Visit 2 (approximately 6 weeks after enrollment) and Visit 5 (approximately 7 months after enrollment)	The percent reduction in wound area at Visit 5 (final visit) relative to the size at randomization visit (visit 2). Wound surface area will be calculated and maximal wound depth will also be measured using ImageJ overlay software technology. Two assessors examined the wound surface area at each visit using ImageJ. This is the outcome as reported by the secondary assessor. A negative value indicates an increase in wound size; a positive value indicates a decrease in wound size.
