FDA Clinical Trials

FDA Clinical Trials
Each year hundreds of patients are referred to medical clinics, such as OrthoCarolina, P.A., for state-of-the-art care and for participation in clinical trials. Clinical trials are designed to develop new devices, evaluate new medications, improve materials and systems, and improve surgical procedures. At the present time, the OrthoCarolina Research Institute is working with fourteen FDA-controlled clinical trials and two Humanitarian Device Exemption (HDE) studies that serve and support the public in providing state-of-the-art surgical treatments and techniques. Representative of these investigative trials are a total shoulder prosthesis design and instrumentation evaluation, a shoulder stability device study, an ankle fusion and ankle arthroplasty comparison, an assessment of design and materials for total joint replacements, and an evaluation of treatment options for diabetic foot infections.

All clinical trial proposals and studies are reviewed and approved by the OCRI Research Advisory Committee (RAC) and an Institutional Review Board (IRB) prior to implementation. Stringent protocols are required to ensure the safety of all participating individuals and to make certain that participating surgeons follow the same study procedures and guidelines.

Sports Medicine

Title: Post-Market, Longitudinal Data Collection Study of DeNovo® NT for Articular Cartilage Defects of the Knee CSU2010-22B
Sponsor: Zimmer
Investigators: Drs. James Fleischli, Dana Piasecki, and Aaron Hewitt, PA-C
Objective: The purpose of this post-market study, is to collect additional long-term outcomes for DeNovo® NT treatment of articular cartilage lesion(s) of the knee in a standard clinical setting. Outcomes to be assessed include pain, function, activity levels and healthcare resource use. This is a post-market, multicenter, cohort study of the commercially-available DeNovo® NT graft.

Studies Closed to Enrollment (Long-term follow-up):

Total Joint Replacement

A prospective, multicenter, non-randomized, clinical outcomes study of the R3® Acetabular System in patients with degenerative hip disease
Sponsor: Smith & Nephew
Investigator: John L. Masonis, MD
Objective: To determine the long-term safety and effectiveness of the R3 Acetabular System.

Title: A Prospective, Multi-Centered Study of the Birmingham Hip Resurfacing System
Sponsor: Smith & Nephew
Investigator: John Masonis, MD
Objective: To evaluate the longer-term safety and effectiveness of the BHR system. 

Prospective Multicenter Post Approval Study of the LPS-Flex Mobile Bearing Knee (Protocol#: 07-100)
Sponsor: Zimmer, Inc.
Investigators: Drs. Water Beaver and Thomas McCoy
Objective: The objective of Post Approval Study (PAS) is to assess the long-term performance of the NexGen® LPS-Flex Mobile Bearing Knee in the treatment of patients with severe knee pain or degenerative knee disease.

Title: PMA Post-Approval Study - CoMplete™ Acetabular Hip System (CoM)
Sponsor: DePuy/Johnson & Johnson
Investigators: Drs. Thomas Fehring, Bill Griffin, Bo Mason
Objective: Post Marktet Approval study on the
CoMplete™ Acetabular Hip System (CoM). Only patients who previously participated in the IDE clinical trial are eligible for this study.

Safety of the AFRS device will be evaluated by the incidence, severity and device or procedure relatedness of all adverse events over the 24 month assessment period as compared to the control group. Effectiveness of the AFRS will be based on the improvement in symptom-related questionnaire scores, function, and neurological status.

A Humanitarian Use Device is a device used to diagnose or treat a disease or condition that affects fewer than 4,000 individuals in the United States per year and for which no similar device is available. The U.S. Food and Drug Administration (FDA) approves the use of Humanitarian Devices based primarily on evidence that it does not pose a significant risk of injury to the patient and that the potential benefit of the device to the health of the patient outweighs the risk of its use.

Title: HDE Application for Vertical Expandable Prosthetic Titaniium
Investigator: J. Michael Wattenbarger, MD
Objective: The Vertical Expandable Prosthetic Titanium Rib (VEPTR) is authorized by Federal law for use in the treatment of Thoracic Insufficiency Syndrome (TIS), the inability of the thorax to support normal respiration or lung growth, in skeletally immature patients. The effectiveness of this device for this use has not been demonstrated.
