Study start date: April 15, 2025Actual date on which the first participant was enrolled.

This clinical trial focuses on evaluating a treatment for people with chronic diabetic foot ulcers, a common problem for those with diabetes. The study uses a special gel called Tropocells Autologous PRF, which is made from the patient's own blood, to help heal these wounds. By testing this new approach, the study aims to see if this treatment can effectively close these stubborn ulcers and improve healing overall, addressing a significant issue for many diabetic patients who struggle with foot wounds that do not heal properly. Participants in the study first enter a two-week period where they receive regular care, including wound cleaning and special dressings. If their wounds do not improve by at least 20%, they move on to the 12-week treatment phase. During this phase, they receive the Tropocells gel on their wounds weekly, in addition to standard care. The study measures how well the wounds heal, looking for complete closure and checking for any side effects. Participants with fully healed wounds are then monitored for a few more months to ensure the wounds stay closed. This research helps understand the safety and effectiveness of the treatment in promoting wound healing.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details
30 patients to be enrolledTotal number of participants that the clinical trial aims to recruit.
Treatment Study
These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.

How participants are assigned to different groups/arms
In this clinical study, all participants receive the same treatment. Since there is only one group, there is no need for randomization or assignment to different arms. This type of study is often used to test a new treatment without comparing it to another.

Other Ways to Assign Participants
Randomized allocation
: Participants are assigned randomly, like flipping a coin, to ensure fairness and reduce bias.

Non-randomized allocation
: Participants are assigned based on specific factors, such as their medical condition or a doctor's decision.

How treatments are given to participants
In this study, all participants receive the same treatment. This approach is often used to evaluate the effects of a single intervention without comparing it to another.

Other Ways to Assign Treatments
Parallel assignment
: Participants are split into separate groups, each receiving a different treatment.

Cross-over assignment
: Participants switch between treatments during the study.

Factorial assignment
: Participants receive different combinations of treatments.

Sequential assignment
: Participants receive treatments one after another in a specific order, possibly based on individual responses.

Other assignment
: Treatment assignment does not follow a standard or predefined design.

How the effectiveness of the treatment is controlled
In a non placebo-controlled study, no participants receive an inert substance (placebo) to compare outcomes. Instead, all participants receive either the experimental treatment or an alternative treatment (often the Standard of Care). This method allows researchers to compare the effects of the experimental treatment with those of a different active intervention, rather than a placebo.

Other Options
Placebo-Controlled
: A placebo is used to compare the effects of the experimental treatment with those of an inert substance, isolating the true treatment effect.

How the interventions assigned to participants is kept confidential
Everyone involved in the study knows which treatment is being given. This is typically used when it's not possible or necessary to hide the treatment details from participants or researchers.

Other Ways to Mask Information
Single-blind
: Participants do not know which treatment they are receiving, but researchers do.

Double-blind
: Neither participants nor researchers know which treatment is given.

Triple-blind
: Participants, researchers, and outcome assessors do not know which treatment is given.

Quadruple-blind
: Participants, researchers, outcome assessors, and care providers all do not know which treatment is given.

Treatment Groups
Group I
Experimental
During Screen-the participant will be treated with standard of care (SOC) for 2 weeks, including education, nutritional supplement, weekly wound assessments and care with off-loading. After the two weekly visits, subjects who meet the inclusion/exclusion criterion, show adequate perfusion and area reduction less than 20%, and comply with the standard of care will be enrolled in the Active Treatment Phase. During the Active Treatment Phase, subjects will be treated weekly with TropoCells® Autologous Platelet-rich Fibrin (PRF) for twelve (12) weeks and continued SOC. Wound area will be documented with measures and photographs before and after cleansing and debridement (as needed). Clean wounds treated topically with active therapy will be covered with a non-adherent layered absorbent foam dressing with an external protective third layer. Mild compression will be applied with continued off-loading at least 2 week after closure. Follow-up evaluation after closure at 1 and 3 months.

Study Objectives
Primary Objectives

* An independent validation will be performed by an independent wound care specialist who will determine if the wound is fully closed, demonstrating 100% re-epithelialization persisting for two (2) subsequent weekly assessments. The validation will be reviewed with the treating researcher and the PI to formalize the results reported to the biostatistician for analysis. The biostatistician will perform and report the following analysis. * Number of subjects achieving complete epithelialization at 12 weeks in the Intent to Treat (ITT) population. * Number of subjects achieving complete epithelialization at 12 weeks in the Per Protocol (PP) population.
Secondary Objectives

The biostatistician will measure and report: 1. Adverse Events (AE), including any untoward or unfavorable medical occurrence in a human study participant, including any abnormal sign (e.g. abnormal physical exam or laboratory finding), symptom, or disease, temporally associated with a participant's involvement in the research, whether or not considered related to participation in the research, and 2. Serious Adverse Events (SAE), including any adverse event that: i) results in death, ii) is life-threatening, or places the participant at immediate risk of death from the event as it occurred, iii) requires or prolongs hospitalization, iv) causes persistent or significant disability or incapacity,and/o v) results in congenital anomalies or birth defects vi) Is another condition which in the investigator's judge to represent significant hazards, and 3) Unanticipated Problem (UP): Defined by DHHS 45 CFR part 46 as any incident, experience, or outcome that meets the criteria.
