Safety Study of Acellular Adipose Tissue for Soft Tissue Reconstruction

Completed · Phase 1

Conditions studied: Healthy Volunteers

In brief

The purpose of this study is to assess the safety and tolerability of acellular adipose tissue (AAT), intended for the repair of soft tissue defects in humans, in healthy volunteers. The investigators hypothesize that AAT will be safe and well tolerated upon injection into human soft tissue.

Who can join

Age: 18 and older, up to 65. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• Healthy men and women aged 18-65 years who have sought elective surgery for the removal of redundant tissue of the abdomen (abdominoplasty or panniculectomy) or arm (brachioplasty).
• Willingness to delay elective surgery up to 12 weeks in order to participate in the study.
• Consent to photography for research purposes.
• Willingness to follow study requirements.
• Ability to give informed consent.
• Participants must be willing to perform follow up visits for up to 5 months.
• Undergo complete blood count (CBC) with Differential and Serum Chemistry. (Results must fall within 1.5 times the normal ranges for all values for candidates to be eligible.)
• Men and Women of reproductive potential: Willingness to use approved methods of birth control or abstain from sexual intercourse from screening until removal of the AAT implants.
• Definition of non-childbearing potential for Women: amenorrhea (previous 12 months) or surgically sterile (bilateral tubal ligation, bilateral oophorectomy, or hysterectomy).
• Definition of non-reproductive potential for Men: confirmed surgically sterile (vasectomy >3 months prior to screening).

You may not qualify if…

• Patients seeking elective surgery for the removal of redundant tissue from areas other than the abdomen or arm.
• Use of AAT in patients exhibiting autoimmune connective tissue disease is not recommended. When applied properly, AAT has been shown to support the migration of host cells from the surrounding tissue. Therefore, this study will exclude patients with conditions that could inhibit migration of host cells including, but not limited to, the following:
• Fever (oral temperature >99º F at time of screening)
• Insulin dependent diabetes
• Low vascularity of the tissue intended for elective excision
• Local or Systemic Infection
• Mechanical Trauma
• Poor nutrition or general medical condition
• Dehiscence and/or necrosis due to poor revascularization
• Specific or nonspecific immune response to some component of the AAT material
• Infected or nonvascular surgical sites
• Known cancer or receiving treatment for cancer
• Pregnant or Lactating females
• Inability to cooperate with and/or comprehend post-operative instructions
• Inability to speak or read English
• Known allergy or sensitivity to Penicillin, Streptomycin, or Amphotericin B
• Any other reason the study physicians judge would be a contraindication for receiving AAT injections
