Clinical trials Below are current clinical trials.501 studies in Oncology (Medical) (open studies only). Filter this list of studies by location, status and more. Study of Pembrolizumab (MK-3475) vs Standard Therapy in Participants With Microsatellite Instability-High (MSI-H) or Mismatch Repair Deficient (dMMR) Stage IV Colorectal Carcinoma (MK-3475-177/KEYNOTE-177) Rochester, Minn., Scottsdale/Phoenix, Ariz. In this study, participants with MSI-H or dMMR advanced colorectal carcinoma will be randomly assigned to receive either pembrolizumab or the Investigator's choice of 1 of 6 standard of care (SOC) chemotherapy regimens for the treatment of advanced colorectal carcinoma. The primary study hypothesis is that pembrolizumab will prolong progression-free survival (PFS) or overall survival (OS) compared to current SOC chemotherapy. A Study of the Use of Cold Caps to Prevent Hair Loss in Chemotherapy Patients Rochester, Minn. The purpose of this study is to learn, in patients’ own words, what cancer patients who are using a cold cap to prevent hair loss are experiencing. Ventricular Remodeling and Myocardial Deformation in Patients Undergoing Chemotherapy for Sarcomas Rochester, Minn. The aim of this study is to determine if there is subclinical systolic or diastolic myocardial mechanical dysfunction by 2D and 3D speckle tracking echocardiography derived strain and strain rate in this patient population at baseline, during and after chemotherapy. This could be an early marker of myocardial dysfunction in patients treated for sarcoma. A Study to Develop a Biorepository of Blood Samples from Cancer Patients Participating in the Gemini (IRB 19-006717) Protocol Jacksonville, Fla., Scottsdale/Phoenix, Ariz. The purpose of this study is to develop a biorepository of blood samples from cancer patients participating in the Gemini (IRB 19-006717) protocol. These samples will be used for future biomarker discovery and other translational studies. A Study to Test Nivolumab with Usual Chemotherapy Treatment or Usual Chemotherapy Treatment Alone to Treat Recurrent or Metastatic Nasopharyngeal Cancer Jacksonville, Fla. The purpose of this study is to compare the effect of adding nivolumab to the usual chemotherapy (cisplatin or carboplatin with gemcitabine) versus the usual chemotherapy alone in treating patients with nasopharyngeal cancer that has come back (recurrent) or spread to other places in the body (metastatic). Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as cisplatin, carboplatin, and gemcitabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving nivolumab with the usual chemotherapy may work better than the usual chemotherapy alone in treating patients with nasopharyngeal cancer. A Study of DNA/RNA Sequencing Results on the Clinical Management of Patients with Advanced Malignancies Rochester, Minn., Jacksonville, Fla., Scottsdale/Phoenix, Ariz. The purpose of this study is to assess practice patterns and changes in treatment recommendations based on the results obtained from a clinically available, comprehensive next generation DNA/RNA sequencing assay. A database of paired clinical and sequencing data will also be established for future research. Study of Breast Cancer Risk Assessment in Female Patients with Benign Breast Disease Rochester, Minn., Jacksonville, Fla. The purpose of this study is to to bring molecular risk prediction for breast cancer into the clinical arena through: the establishment of a large tissue repository from a retrospective cohort of women with benign breast disease with complete and long-term clinical follow-up to identify those who developed breast cancer (cases) and those who did not (controls); the application of potential biomarkers of risk to this archival tissue set; and, the discovery of new, potentially relevant biomarkers of risk in fresh and frozen specimens of benign breast disease. A Study to Assess Clonal Diversity of Freshly Taken ESD Specimens Rochester, Minn. Inclusion Criteria: Patients with Barrett’s Esophagus (BE) or Esophageal Adenocarcinoma (EAC) that are planned for Endoscopic Submucosal Dissection (ESD) treatment. Exclusion Criteria: Patients without BE or EAC or that are not planned for ESD treatment. Trans-Pacific Multicenter Collaborative Study of Minimally Invasive Proximal Versus Total Gastrectomy for Proximal Gastric and Gastroesophageal Junction Cancers Rochester, Minn. The purpose of this study is to compare the symptoms of patients who have a MIPG to the symptoms of patients who have a MITG. Detection of Mutant Circulating Tumor (CT)Dna in Uveal Melanoma With Development of a Droplet Digital Pcr (Ddpcr) Assay Rochester, Minn. The purpose of this study is to design, develop and assess the performance characteristics of a ddPCR assay for the detection of mutations associated with uveal melanoma. The performance characteristics of the ddPCR assay for the detection of ctDNA mutation in uveal melanoma patients will be assessed by comparing the mutation results obtained for the ddPCR assay on blood to those obtained on paired paraffin embedded tumors.

The patient comes first. So the mission and research here is to advance how we can best help the patient, how to make sure the patient comes first in care. So in many ways, it's a cycle. It can start with as simple as an idea worked on in a laboratory, brought to the patient bedside, and if everything goes right — and let's say it's helpful or beneficial — then brought on as a standard approach. And I think that is one of the unique characteristics of Mayo's approach to research — that patient-centeredness — that really helps to put it in its own spotlight.
