43 Clinical Trials for Various Conditions
The goal of this clinical trial is to validate the safety and effectiveness of a two-stage approach for minimally invasive craniofacial soft tissue reconstruction using autologous fat grafting in wounded service members and veterans. The main questions it aims to answer are: 1. Will treating subjects with post-traumatic craniofacial deformities using fresh fat grafts, followed by a second treatment 3 months later with cryopreserved fat stored at -80°C, improve facial tissue regeneration and appearance? 2. How do volume retention and tissue health change between fresh and cryopreserved grafts in humans? 3. How do factors such as cellular composition of the graft, patient demographics, and medical conditions (including diabetes, tobacco use, medications, age, and BMI) affect fat graft volume retention and overall outcomes? Researchers will compare results from the second-stage cryopreserved fat grafting to fresh fat grafting to assess outcomes like volume retention, patient recovery, and cost reduction. Participants will: Undergo an initial fat grafting procedure. Have additional fat harvested and cryo-stored for use in a second-stage procedure. Receive the cryopreserved fat in a later stage without the need for a second fat harvest. Receive small test injections behind each ear for later analysis. Provide data on demographics and medical conditions for correlation with outcomes.
The purpose of this research is to collect data on the short and long-term effects of facial fat grafting by injectable tissue replacement and regeneration in the midfacial zone, with the use of the VialityTM system. The Viality system is a US Food and Drug Administration (FDA) cleared device.
The purpose of this study is to observe the effect of autologous fat grafting on soft tissue reconstruction of the breast following radiation treatment. Moving fat from one part of the body to another has been used for reconstruction for hundreds of years. However, it is not fully understood how well this works in reconstruction after radiation is used for cancer treatment.
This is an open label multi-center study with the aim of evaluating the efficacy of adipose tissue processed with the SyntrFuge™ system in facial aesthetics and contouring. Patients will be enrolled to the treatment group with adipose tissue processed with the SyntrFuge™ system followed by an injection of autologous microsized adipose tissue in the treatment sites.
The goal of this study is to specifically examine changes in facial skin appearance after facial fat grafting with autologous fat tissue that has either been washed with sterile saline before injecting, or left unwashed. This will be testing two variations of a standard of care surgical procedure, in two cohorts of subjects. One group will receive washed fat, and one group will receive unwashed fat, to both sides of the face. There are no experimental devices, drugs, or biological agents being used in this study. All fat tissue is autologous from the subjects treated. Significance: This study will provide evidence that may directly impact clinical practice for a common procedure in plastic surgery. Regardless of whether the null hypotheses is accepted or rejected, the data will be of direct clinical use and impact practice in the operating room.
Prospective, multi-center, non-randomized, open-label, post-market clinical study evaluating adipose graft retention over time from lipoaspirate processed using the AuraGen 1-2-3™ with AuraClens™ Lipoaspirate Wash System.
The purpose of this study is to compare fat graft retention over time from lipoaspirate processed using two FDA-cleared devices: the Revolve System (K120902) and the AuraGen 1-2-3 with AuraClens Lipoaspirate Wash System (BK190433).
The purpose of this study is to learn whether there is a superior fat processing method in terms of graft retention in breast reconstruction after mastectomy.
This single-center, clinical trial consists of a one autologous fat grafting treatment followed by 3-month and 6-month post-treatment visits in order to assess the efficacy of fat grafting when used by men and women with facial acne scars.
Fecal Incontinence affects an estimated 2-20% of the general population, and up to 50% of the elderly and institutionalized population. Patients with incontinence tend to suffer in silence; they often do not seek help because of embarrassment and stigma. They often become confined to their homes because they are afraid of having an "accident". Although this is not a life-threatening condition, the psychological, emotional, and social impact can be devastating.
Multi-center, prospective, open-label, single arm study. The study aims to evaluate the safety and efficacy of Laser Assisted Liposuction procedure performed with the LipoLife system. The study will include twenty (20) eligible subjects, that are willing to undergo abdominal or outer thighs laser-assisted liposuction. Five to twenty (5-20) subjects out of this study group should also be eligible for facial fat grafting. Follow up visits to evaluate study endpoints will take place at 1, 3 and 6 months after the surgery.
Title: The Volumetric Analysis of Fat Grafting for Aesthetic Body Contouring. Subjects who wish to undergo fat grafting for aesthetic body contouring will be offered enrollment to the study. The study will consist of a Screening/Baseline visit, Surgery day and 3 follow up visits. Each follow up visit will utilize Vectra 3D photography (Canfeild, NJ) to collect volumetric data. At the conclusion of the study, Volume data from Baseline and 3 follow up visits will be analyzed to determine fat retention rates.
This trial studies how well REVOLVE or PureGraft technique works in processing fat grafts for patients who are undergoing breast reconstruction. During breast reconstructive surgery that uses autologous fat grafting (transplanting fat tissue from one part of your body to another), fat tissue is removed from the body (usually the abdomen, buttock, or thighs) and injected into another part of the body. This tissue must be "processed" (sometimes referred to as "washed" or "prepared") before being inserted back into the body. It is not yet known whether REVOLVE or PureGraft technique may work better in retaining graft fat after surgery.
Urinary incontinence affects more than 200 million people worldwide. In women, childbirth or menopausal aging atrophic vagina, lack of estrogen stimulation of muscular turgor of the vagina, decrease tone of the urogenital diaphragm, attenuation and weakening of the urethral sphincter all result in stress incontinence, urge incontinence and sometimes mixed incontinence respectively. The purpose of this study is to evaluate reconstructive lipoplasty with micro-fragmented autologous adipose tissue (Lipogems®) in female patients with stress urinary incontinence. This is a prospective study of 25 subjects that will be evaluated over a period of one year. The treatment consist of the injection of micro fragmented adipose tissue, previously extracted from the patient in the area of the urethral sphyncter. Patients will have follow ups at 6 months with Urodynamic studies to measure the pre-post injection differences to-date. Visual analog score questionnaire and report in subjective improvement, pad use and stress cough test will be documented at 1, 3, 6, and 12 months follow-up.
This randomized clinical trial studies and compares 3 techniques in performing autologous fat grafting (AFG) in patients undergoing surgery to reshape or rebuild (reconstruct) a part of the body changed by previous surgery and inserted into another part of the body. AFG, also called fat injections or fat transplant, is a procedure in which an individual's own body fat (usually from abdomen or legs) is used during reconstructive surgery. Doctors want to compare 3 techniques for processing the fat tissue collected during surgery and the length of time needed to complete each AFG technique and surgery. Comparing 3 AFG techniques and the time to complete them during surgery may help doctors determine the best technique to perform fat grafting in the future.
The specific aim of this outcomes study is to assess if the volume of fat that is injected into the foot is retained at 6 months, to determine the retention over time, and assess the quality of the bone before and after treatment. We will also correlate adipose stem cell characteristics to the fat retention over time.
This phase two, randomized, double-blind study is designed to demonstrate the enhanced efficacy of SVF-enriched autologous facial fat grafts, in relation to standard, non-SVF enriched, facial fat grafts by evaluating volumetric retention and contour of the engrafted region over the course of one year.
Plantar heel pain is the most common problem of the foot. Plantar fasciitis is the leading cause of this pain, accounting for 11-15% of all foot symptoms seeking professional care, and occurs in 10% of the US population. The cause of heel pain can be from bone, soft tissue, nerve, or systemic disease. The second most common cause of heel pain is fat pad atrophy, followed by a combination of both fat pad atrophy and plantar fasciitis. \[1-4\] Fat pad displacement may be seen in the heel as well. Current treatments for plantar fasciitis include stretching and external support with orthotics with the goal of reducing local pressure as well as tissue breakdown.\[5\] However, patient compliance with extrinsic devices is challenging, and they may experience increased friction, irritation and breakdown at a different location on the foot due to thickness of the device in the shoe. Also, the patient must replace the device as soon as it breaks down but the breakdown often goes unnoticed. Failure of conservative management may lead to treatment with steroids or surgical intervention by endoscopic plantar fasciotomy, open fasciotomy or excision of bone spurs. Injection of steroids can instigate or exacerbate pre-existing heel fat pad atrophy. Autologous fat grafting to the heel may reduce plantar pressures, and thus serve as a treatment for heel pain. Autologous fat grafting is currently under investigation for a myriad of clinical scenarios.\[6-19\] Even though autologous fat grafting is not yet an established therapeutic approach for the cited indications, some of the reported results have been intriguing.\[19\] The variable resorption of fat, however, is an important confounding factor in all these studies. Currently the literature reports fat retention rates ranging from 25% to 80%.\[20\] The specific aim of this study is to assess the adipose stem cell characteristics in patients undergoing autologous fat grafting for heel fat pad atrophy and correlate these characteristics with fat retention. Data from this study will help determine the characteristics of the adipose stem cells in this population and open the door to additional studies. This pilot study will also help build new collaborative efforts between Foot and Ankle Specialists, Plastic Surgery, and Adipose Stem Cell Biologists, combining biomechanical expertise with fat grafting and basic science expertise.
The purpose of the study is to evaluate the safety and efficacy of breast reconstruction using Autologous Fat Grafting (AFG) for women post lumpectomy that have contour defects. The study hypothesis is that AFG has emerged as a less invasive alternative to breast reconstruction post mastectomy. AFG could be used to treat breast contour defects with much less invasive outpatient surgery, using the patient's own cells and tissues, which overall reduces risk.
This study will examine the impact of the fat grafting procedure on facial appearance and quality of life over time by precisely measuring soft tissue volume with CT scans, assessing appearance with 2D and 3D photography and standard photography and evaluating quality of life through various validated psychosocial measures. This study will be a very important evaluation of the effectiveness of this therapy, and will help guide clinicians in applying this technique. Additionally, laboratory testing of the injected fat material will be performed so that the results may be correlated with clinical outcomes in the future. The study endpoints include the analysis of the graft site via study procedures at different time points, the comparison of cotton rolling to centrifugation method of autologous fat grafting, as well as the correlation of cell behavior of the laboratory assays with clinical outcomes.
We propose a prospective, randomized clinical study to assess the efficacy of minimally invasive autologous fat transfer addressing pain and poor prosthetic fit at amputation sites.
The etiology of plantar fat pad atrophy may be age-related, due abnormal foot mechanics, steroid use, or collagen vascular disease. Displacement or atrophy of the fat pad can lead to osseous prominences in the forefoot that may be seen with painful skin lesions. Disease states, such as diabetes, may have loss of soft tissue integrity. Fat pad atrophy, regardless of the etiology, may result in significant pain, epidermal lesions, or metatarsalgia. In sensate patients, the pain can lead to emotional and physical pain, leading to productivity and financial losses. It is well documented that plantar pressure is directly correlated with plantar tissue thickness, with the loss of plantar fat being a fundamental mechanism for pressure related foot disorders.Autologous fat grafting to areas of plantar fat pad atrophy may reduce plantar pressures, and thus serve as a treatment for metatarsalgia, corn and callus prevention, and possibly ulcer prevention in diabetics. Plastic surgeons, with significant skills in fat grafting, can make a significant contribution. Current treatment modalities for fat pad atrophy include silicone injections, fat injections, and other temporary fillers; however, no objective studies using autologous fat have been performed. Approximately 30 adults who experience pain from fat pad atrophy, will have the option to participate. Through a randomized, controlled, cross-over study, some patients will receive autologous fat grafting, while some will receive standard of care podiatric treatment, then cross-over to fat grafting treatment after a year. Through pedobarograph and ultrasound assessments, the focal pedal pressure and tissue thickness following treatment will be documented over two years. We hypothesize that fat grafting for areas of increased pedal pressure in well-controlled diabetics will help decrease foot pressure during gait and increase soft tissue thickness on the foot pad, ultimately reducing pain. We also hope to demonstrate that by using autologous fat with evidence-based fat transfer techniques, results may be durable. This pilot study will help build new collaborative efforts between Foot and Ankle Surgery, Podiatry and Plastic Surgery, combining expertise in foot biomechanics with reconstructive fat grafting.
The overall purpose of this research is to evaluate the physical changes that occur over time after fat grafting for craniofacial trauma. This protocol is similar to an existing study (IRB# PRO0906101) presently conducted at the University of Pittsburgh by the same research team which utilizes fat grafts. The preparation of the fat graft material in each clinical trial is processed differently evaluating the effects of graft resorption after treatment.
The primary purpose of this study is to demonstrate the safety of injecting the Stromal Vascular Fraction (SVF) \[containing Adipose Derived Stem Cells (ADSCs)\] enriched fat grafts into regions of the face that require enhancement. The safety of SVF will be evaluated throughout the course of the study phase through the assessment of laboratory values, physical examinations, adverse events, safety phone calls etc.
Fat grafting represents a technique with great potential to improve outcomes in minimally invasive facial reconstruction. Fat grafting has already been demonstrated as a safe and minimally invasive technique over decades of widespread practice in plastic surgery. In our current study of fat grafting for facial deformities (IRB# PRO09060101), we have treated 9 subjects without adverse event and all have had a significant improvement. Since all methods of treatment and evaluation are the same in this study, we will be able to use the data in our prior study as additional control data. We hypothesize that repeating the fat grafting in subjects with previous facial fat grafts will enable successful restoration of tissue volume and craniofacial form. Additionally, we hypothesize that the results will be durable and subject quality of life improved. Five (5) subjects (who were previously enrolled into IRB# PRO09060101) will be enrolled to this single center University of Pittsburgh site research study.
It is believed that the average person with an eighty year old life span will walk the distance of the world twice in their lifetime. The foot is comprised of a specialized fat pad to provide shock absorption and protection against breakdown. With all the walking humans do however, foot fat pad breakdown is inevitable. Trauma to the foot is compounded in the diabetic patients due to many reasons: loss of protective sensation secondary to neuropathy, reduced skin hydration, decreased soft tissue elasticity, elevated blood sugars and increased body weight to name a few. Increased foot pressure and decreased fat pad protection are the main contributing factors to callus formation, foot pain and ulcer formation. Fat grafting is a cosmetic and reconstructive procedure that is used sometimes to help improve one's soft tissue thickness, shape and integrity. Autologous fat transplantation is a procedure using a patient's own fat that is taken by a small liposuction tube, from areas with a substantial amount of fat ( i.e. abdomen or thighs) and then transferred into the fat atrophied (decreased or worn out) area (in this case, the foot). The investigators are performing this research in an effort to decrease foot pressure during activity and to increase the soft tissue thickness of the sole of the foot during one's lifetime. Ultimately this could help reduce foot pain, callus formation and even ulcer formation. The goal of this research is to see whether fat grafting will help decrease the prevalence of the aforementioned foot complications. The investigators hope that by using one's own fat tissue, he or she may have a longer duration of relief than by using other methods. This is a randomized, cross-over designed study. Randomized means that patients will be enrolled by chance (like the flip of a coin) to one of two groups for the first part of the study. Cross-over means that, after the first part of the study or at one year, patients will move into the opposite group. One group will receive the fat grafting procedure with one year follow up (year A pathway) and the other will receive standard of care treatment from the patient's primary podiatrist during the first year (year B pathway). After the first year, patients will switch to the opposite year pathway for the next 12 months. Participation in this study will last approximately 24-26 months.
The investigators will assess changes in breast appearance, graft retention and quality of life over one year in patients who have received direct autologous adipose tissue injection for the treatment of objectionable post-surgical breast deformities. These patients have undergone the resection of breast tissue to treat either benign or malignant breast disease.
After people lose an eye, for whatever reason, they often experience fat atrophy of the tissues in the orbit. This leads to a sunken appearance that is often not correctable by a cosmetic shell prosthesis. Current techniques to correct this deformity are inadequate/ invasive. Injection of various gels (Restylane, Radiesse) are temporary had have their own disadvantages. This study seeks to demonstrate an improvement in the retention of injected autologous fat by mixing in autologous PRP (platelet rich plasma).
The objective of this pilot study is to assess the efficacy of minimally invasive autologous fat transfers at the amputation sites and the modulation of pain at the respective sites. Our investigators hypothesize that autologous fat grafting can provide a minimally invasive therapy to effectively mitigate pain syndromes at amputation sites, by introducing volume stable subcutaneous tissue over bony prominences and peripheral nerve trunks, thereby avoiding major surgical revisions and preserving limb length. The investigators further hypothesize that enriching the fat graft with autologous adipose stromal cells, a regenerative medicine approach, will lead to improved retention of the fat graft over time and result in a more favorable outcome. The Investigators will evaluate: 1. Treatment of painful amputation sites in 5 patients with fat grafting, intended to provide additional subcutaneous tissue padding over bony structures and nerve trunks. Limb anatomy and healing of the graft over time, along with stability/persistence of the new tissue, will be assessed by high resolution CT scanning with 3D reconstruction. Patients will be followed for 24 months after treatment to define long term outcomes. Patients will be enrolled who have pain at an amputation site that limits function and/or interferes with the ability to use a prosthesis. 2. Biologic properties of the cells within the fat graft and correlate with clinical outcomes. This will include adipose stem cell yield per volume of fat tissue, cell proliferation, capacity for adipogenic differentiation, lipolysis, and cell sub-population analysis by multiparameter flow cytometry. Results of these assays will be correlated with graft volume retention to search for predictors of good clinical outcome that are related to variation on adipose biology between subjects. 3. Quality of life measurements in patients before and after autologous fat grafting using validated psychosocial measures. This will include SF 36, the Beck inventory, and instruments designed for assessing limb function.
Traumatic facial injuries, especially those sustained in military combat, are characterized by destruction of bone and soft tissue. While the bony structures of the face can be reconstructed, it is difficult to return the soft tissue back to its original form. Many times, fat grafting, a common cosmetic and reconstructive procedure, is used in hopes of improving the soft tissue deformity. Fat grafting is a procedure in which a person's own fat is taken from areas throughout the body, usually the thighs or abdomen, with a small liposuction tube. The fat is then transferred into the area that has lost volume or fullness. The fullness of the soft tissue area may decrease over time because the transferred fat can be reabsorbed by the body. Altering the current fat grafting procedure, slightly, could lead to less reabsorption and a lasting fullness of the soft tissue area outcome of the fat graft procedure. The investigators are conducting this research study to help us improve the surgical treatment of people who have suffered facial soft tissue loss as a result of trauma. The goal of this research study is to see how each person's fat grafts will maintain the fat over time and to measure the quality of life during a 9 month post-surgical follow-up period. The total duration of participation is approximately 11-12 months. In this study, the investigators will concentrate the fat in the fat grafting procedure to determine whether this process will maintain the fat over time. The areas treated with enhanced fat grafts will be compared with areas treated with standard of care fat grafts. At least two areas of your face will be treated with fat grafts, (standard of care fat grafts and concentrated fat grafts). This study is the second of two clinical studies at the University of Pittsburgh using each person's fat graft with concentration of fat cells in the graft to observe if there is less fat resorption compared to using fat grafts alone. Each study is using a different concentration of fat in the fat graft compared to the first clinical study.
