1. A Study to Assess Pre-analytical Factors Affecting ctDNA Analysis in Early and Locally-advanced Breast Cancer

   Scottsdale/Phoenix, Ariz.

   The purpose of this study is to evaluate the impact of blood collection tube type and processing methods on ctDNA, evaluate the impact of long-term storage of plasma and extracted DNA, and evaluate ctDNA levels at baseline and during treatment for patients with Stage I-III breast cancer.
    

2. Patient Derived Preclinical Models

   Rochester, Minn.

   The objective of this study is to collect tumor specimens (tumor tissues, matched normal tissue when possible, and 50 mL of blood) that may inform cancer biology to eventually improve outcomes for patients with cancer. Additionally, relevant specimens that were previously collected under an IRB approved protocol (13-000942), will be used with approval of the PI of that protocol and patient consent for participation in this protocol.

   The collected tissue specimens will be used to develop preclinical models; i.e., cell lines, patient derived micro-cancer models as well as patient-derived xenograft models. In this study we may profile tumors using genomic and/or proteomic approaches to identify targetable alterations in tumor tissue from patients. To assure that the derived cell lines and micro-cancer models have not been cross contaminated during development with other models in development, DNA sequencing may be used. Using these preclinical models, we will test new therapies in vitro, or in vivo in mice in order to identify novel therapeutics as well as interrogate genes for their role in tumor biology. Guidance for molecular targeted therapy will involve gene analysis of oncogenes and tumor suppressor genes. Results from these studies may provide the rationale for the design of future novel clinical trials. The evaluation of these preclinical models may lead to predictive value related to patient response to therapy as well as clinical trials. With consent, these models may be shared with other investigators internal or external to Mayo Clinic.

3. ALPN-202 With PD-1 Inhibition in Advanced Malignancies

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

   The purpose of this study is to evaluate ALPN-202 with PD-1 inhibition to treat adults with advanced solid tumors or lymphoma.

4. A Study to Assess Dynamic Changes in Plasma Proteome to Identify Early Detection and Treatment Response Biomarkers for HGSOC

   Rochester, Minn.

   This study aims to identify candidate High Grade Serous Cancer (HGSC) early detection and chemotherapy treatment response biomarkers.  For the purpose of this study we define high grade serous cancers to include invasive cancers arising in the ovary and/or fallopian tubes (FT).  Using mass spectrometry we will deeply profile and quantitate dynamic changes in the plasma proteome and N-gylcocapture sub-proteome that occur as a consequence of surgical debulking and platinum-based chemotherapy.  

5. A Study to Evaluate Personalized Molecular Marker and Immunoprofiling to Transform Hepatocellular Carcinoma Treatment

   Jacksonville, Fla.

   The purpose of this study is to evaluate whether profiling aggressive tumors for molecular alterations, together with drug testing in patient-derived 3D models, can provide crucial information for the identification of specific therapeutic targets. Additionally, immunoprofiling of microcancer model systems is crucially necessary data to enable prediction of immunotherapeutic efficacy. We postulate that our innovative approach will establish much needed immune microenvironment information and facilitate the identification of specific sensitivity profiles and biomarker signatures that correlate response to targeted agents (or combinations) with particular tumor profiles.

6. A Study to See if the Depth of Tumor Invasion of Esophageal Carcinoma Predicts Lymph Node Involvement and Cancer Free Survival

   Rochester, Minn.

   The purpose of this study is to see if different depths of submucosal tumor invasion in esophageal cancer can predict lymph node involvement and survival.

7. Testing the Addition of Duvelisib or CC-486 to the Usual Treatment for Peripheral T-Cell Lymphoma

   Rochester, Minn.

   The purpose of this study is to evaluate the effect of duvelisib or CC-486 and usual chemotherapy consisting of cyclophosphamide, doxorubicin, vincristine, etoposide, and prednisone in treating patients with peripheral T-cell lymphoma. Duvelisib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Chemotherapy drugs, such as CC-486, cyclophosphamide, doxorubicin, vincristine, etoposide and prednisone, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. This trial may help find out if this approach is better or worse than the usual approach for treating peripheral T-cell lymphoma.

8. A Study of Cell, Serum, and Bone Marrow Bank for Patients receiving Chimeric Antigen Receptor T Cell Therapy for the Treatment of Cancer

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

   The purpose of this study is to store blood, serum and bone marrow so that they can be used for laboratory studies that may contribute to finding the exact function of the CART cells or T-cell engager therapy such as bispecific and trispecific antibodies and the factors that may determine disease progression and treatment response.

9. Exploring Mechanisms of Action and Resistance of Therapeutic Agents in Patients with B-cell Malignancies

   Jacksonville, Fla.

   This study is being performed to understand the causes of drug resistance and to improve the treatment options for patients diagnosed with B-cell cancers. We aim to identify the reasons why certain therapies work and others don’t and as result- develop new treatments for blood cancers.

10. Testing Nivolumab and Ipilimumab With Short-Course Radiation in Advanced Rectal Cancer

    Rochester, Minn.

    The purpose of this trial is to investigate the effect of nivolumab and ipilimumab when given together with short-course radiation therapy in treating patients with rectal cancer that has spread to other places in the body (advanced). Immunotherapy with monoclonal antibodies, such as nivolumab and ipilimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Giving nivolumab, ipilimumab, and radiation therapy may kill more cancer cells.
