Below are current clinical trials.

Filter this list of studies by location, status and more.

1. Aggressive Malignancy PDX (Avatar) and Cryopreservation Program

   Rochester, Minn.

   The purpose of this study is to assess the ability to successfully create numerous validated patient-derived xenograft (PDX) models from patient tumor specimens obtained at surgery/biopsy via the new Pathology/TRAG cryopreservation protocol, and to generate a large catalog and repertoire of previously unavailable histologically validated PDX.

    

2. A Registry for the Collection and Maintenance of Biological Specimens for Breast Cancer Research

   Rochester, Minn.

   The purpose of this registry is to collect and maintain samples of breast tissue from women and men undergoing surgery for a breast related concern at Mayo Clinic Rochester,  to create a biospecimen resource for the study of benign and cancerous breast conditions.

3. A Study to Compare Somatostatin Analogues with Perioperative Antibiotics versus Prolonged Antibiotics

   Rochester, Minn.

   The purpose of this study is to to determine the individual treatment effect of somatostatin and whether duration of antibiotic therapy coupled with octreotide provides improved outcomes after pancreaticoduodenectomy. 

4. Human Blood and Tissues Repository for Neuroscience Research

   Jacksonville, Fla.

   The purpose of this study is to collect adult human blood, cerebrospinal fluid, brain, and spine tissues/fluids at time of surgery in order to conduct future studies of the cellular mechanisms of tissue invasion utilized by brain and spine tumors of the central nervous system (CNS).

5. A Study to Evaluate Advanced Development of Desorption Electrospray Ionization Mass Spectrometry for Intraoperative Molecular Diagnosis of Brain Cancer

   Jacksonville, Fla.

   The purpose of this study is to explore the translational abilities of desorption electrospray ionization mass spectrometry (DESI-MS) as intraoperative diagnostic tool to identify cancerous versus noncancerous tissue and estimate the percentage of tumor infiltration in tissue biopsies, by monitoring depletion of N-acetylaspartate (NAA) and aberrations of the phospholipid signature of neurological tissue; and to identify the presence of IDH mutations by monitoring the 2-hydroxyglutarate (2HG) and, therefore, differentiate between IDH-mutant and wild-type gliomas.

6. Shoulder Arthroscopy: Functional and Clinical Outcomes

   Rochester, Minn.

   The purpose of this study is to evaluate the clinical and functional outcomes of patients undergoing arthroscopic shoulder surgery.

7. A Study to Compare 3- and 4-Part Proximal Humerus Fractures Undergoing Elected Nonoperative vs. Operative Management

   Rochester, Minn.

   The purpose of this study is to compare validated clinical and functional outcomes between patients who acutely present with 3- and 4-part Proximal Humerus Fractures (PHFs) treated nonoperatively or with rTSA. We hypothesize that in displaced 3- and 4-part proximal humerus fractures, rTSA will have better pain relief and functional outcomes than nonoperative treatment.

    

8. Multi-Center Prospective Validation Study of VTE Risk Prediction Tool in Trauma Patients

   Rochester, Minn.

   Almost one-half million people suffer venous thromboembolism annually in the United States, and one-third die from this disease. Massive bleeding from injury accounts for half of early deaths after trauma. This study aims to prevent the deaths and suffering associated with venous thromboembolism and bleeding by identifying the individual person at high risk of these complications in order to take preventive measures.

9. A Study of Noninvasive Hemoglobin Monitoring in Pediatric Patients Undergoing Orthopedic Surgery

   Rochester, Minn.

   The purposes of this study are to validate noninvasive hemoglobin monitoring in postoperative orthopedic pediatric patients, to evaluate patient, parent, and provider preference of noninvasive hemoglobin monitoring compared to invasive blood draw, and to evaluate cost effectiveness of noninvasive monitoring in comparison to invasive blood draws.

10. A Study to Establish a Living Breast Organoid Biobank for Translational Research

    Jacksonville, Fla., Rochester, Minn., Scottsdale/Phoenix, Ariz.

    Researchers at Mayo Clinic are developing a Biobank of adult stem cell-rich breast organoids, a new research resource to facilitate normal and cancer stem cell research. Subjects in the Biobank will provide samples of excess breast tissue, complete a health questionnaire, and allow access to medical records now and in the future. The Biobank serves as a library for researchers; instead of having to look for volunteers for each new project, researchers can use samples from the Biobank as well as share information already collected.
