Allograft Adipose Matrix (AAM) in Subcutaneous Dorsal Wrist

August 9, 2016 updated by: Musculoskeletal Transplant Foundation

Local Skin and Volume Changes With the Use of Allograft Adipose Matrix (AAM) in the Subcutaneous Human Dorsal Wrist, a Pilot Study

This is a 16 week pilot study to assess short term outcomes of an injectable allograft adipose matrix (AAM) in the subcutaneous space in the dorsum of the wrist. A total of 30 patients will be enrolled at 2 sites and will be followed for sixteen weeks. Volume retention and local skin changes will be observed and documented prior to and following injection at week 0 and at follow up visits at 2, 10 and 16 weeks. Evaluations will be done via photographic analysis at week 0,2,10 and 16 weeks and half of the patients will undergo magnetic resonance imaging at week zero and at week 16. The dominant wrist will serve as a control and will receive no injection. Analysis includes volume retention, tissue analysis, local skin changes and adverse events, if any.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This pilot study focuses on three primary objectives: to evaluate volume retention at the site of injected allograft adipose matrix (AAM), to obtain tissue analysis via magnetic resonance imaging at the site of injection and to evaluate local skin changes as a result of the injection of AAM with follow up over a 16 week period. The AAM is derived from cadaveric human adipose recovered, processed, dehydrated and distributed by the study sponsor from thoroughly screened donors. It is distributed with instructions for rehydration prior to single use. The injection site (non-dominant wrist) will be infiltrated with Lidocaine 0.5%, Epinepherine 1:200,000 prior to AAM injection. Volume of AAM necessary to create a centered 2-3mm raised wheal at the first proximal dorsal wrist crease will be administered. Photographs taken prior and following the injection and at each of the subsequent visits are taken with a color standard within the frame for later color change analysis of the injection surrounding area. Both the control and treated hand/wrist will be photographed separately in numerous positions (extension, flexion and several degrees of either) at heart level, at week 0,2,10 and 16 weeks. A clinical assessment scale for evaluation of skin changes in appearance will also be done at these same times. Patients will be advised to avoid prolonged pressure to the dorsal wrists, wear no jewelry or wrist bands, etc., for the duration of their participation in the study. Those patients designated for MR imaging shall have their MRIs done within 3 to 5 days of their week zero and week16 visits. The images shall be read and documented by a single independent radiologist.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

35 years to 75 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

Female

Sampling Method

Non-Probability Sample

Study Population

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
