1. Innovative CAR-TIL immunotherapy against melanoma

   Jacksonville, Fla.

   The chimeric antigen receptor (CAR) T-cell therapy is a revolutionary cellular immunotherapy strategy that has transformed the treatment of B cell malignancies by engineering T cells to recognize B cell specific tumor markers; however, attempts to treat solid tumors with CAR T-cells have identified unique challenges that have rendered CAR T cells less effective against these tumors. Conventional CARs are designed to target tumor-associated antigens, but antigenic heterogeneity and the variable nature of surface antigen expression provide escape mechanisms for solid tumors from CAR T-cell attack. [1, 2] The solid tumor stroma acts as an immunosuppressive cloud that impedes the homing of peripheral CAR T-cells into the tumor microenvironment (TME). The hostile TME can also drive CAR T-cells to functional exhaustion and metabolic dysfunction, thus blunting the therapeutic efficacy of CAR T-cells.[3] Oncolytic viruses or radiation that generate local inflammation in the TME have been shown to promote T cell homing and infiltration [4] but do not address the exhaustion of tumor infiltrating lymphocytes (TILs). The PD-1/PD-L1 cascade allows tumors to evade the immune system by suppressing T cell function within the TME. [5, 6] An ideal adoptive cellular therapy must possess the ability to not only return to the site of the tumor but must also retain cytotoxic potential after a recognition event. We present here a CAR design that allows PD-1 to recognize PD-L1 on the tumor; however, the intracellular CAR design is one that results in T cell activation as opposed to inhibition. We hypothesize that targeting melanoma with a PD-1 (MC9324) CAR TIL therapy would capitalize on the tumor homing machinery of the TIL to drive the CAR TIL to the tumor where engagement of the PD-1 domain of the CAR with PD-L1 on the tumor cell would result in T cell cytotoxic killing.

2. Analyses of Metabolic Agents Following Brain Radiation

   Rochester, Minn.

   The purpose of this study is to determine the feasibility of serial cerebrospinal fluid (CSF) assessments to evaluate the pharmacodynamic impact of agents targeting radiation-induced biology administered following completion of brain radiation.

3. A Study of a New Way to Treat Children and Young Adults With a Brain Tumor Called NGGCT

   Rochester, Minn.

   The purpose of this study is to monitor outcome to ensure that children and young adults with localized central nervous system (CNS) non-germinomatous germ cell tumors (NGGCT) treated with Induction chemotherapy followed by response evaluation and whole ventricular + spinal canal irradiation (WVSCI) will maintain the excellent 2-year progression free survival (PFS) rate as compared to ACNS0122. Also, to improve disease control by decreasing the number of spinal relapses for patients who achieve a complete response (CR) or partial response (PR) and receive WVSCI as compared to whole ventricular radiation on ACNS1123.

4. A Study of the Safety, Tolerability, Drug/Body Interactions, Biological and Clinical Activity of MSB0011359C (M7824) in Metastatic or Locally Advanced Solid Tumors

   Scottsdale/Phoenix, Ariz.

   The purpose of this study is to assess the safety, tolerability, drug/body interactions, and the biological and clinical activities of MSB0011359C (M7824) at different dose levels given to patients who have metastatic or locally advanced solid tumors.

5. Cell, Serum, and Buccal Bank for Patients with Chronic Myeloid Disorders and Acute Leukemia

   Rochester, Minn.

   This study is being done to store blood, buccal (cheek) cells, genetic material including DNA (deoxyribonucleic acid) and RNA (ribonucleic acid), and bone marrow so that they can be used for laboratory studies that may contribute to finding the causes of disease and factors that may determine disease progression and treatment response.

6. Sapanisertib in Treating Patients With Metastatic or Refractory Pancreatic Neuroendocrine Tumor That Cannot Be Removed by Surgery

   Scottsdale/Phoenix, Ariz., Rochester, Minn.

   This phase II trial studies how well sapanisertib works in treating patients with pancreatic neuroendocrine tumor that has spread to other places in the body, does not respond to treatment, or cannot be surgically removed. Drugs such as sapanisertib may stop the growth or shrink tumor cells by blocking some of the enzymes needed for cell growth

7. A Clinical Use Application for the Humanitarian Use Device Exemption Use Protocol of TheraSphere for Treatment of Unresectable Primary or Secondary Liver Neoplasia

   Eau Claire, Wis.

   This protocol allows multiple treatments with TheraSphere® that may be delivered on an outpatient basis. Patients may receive a single dose to a liver lobe or segmental treatment delivered as a sequence of treatments approximately 30-90 days apart. The principal clinician, working with a multidisciplinary team, will develop a specific treatment plan for each patient, based upon the presenting condition of the patient, the vascular anatomy and the desired goal of treatment.

8. A Study to Collect Thoracic Specimens to Develop a Thoracic Specimen Registry

   Rochester, Minn., Scottsdale/Phoenix, Ariz.

   The primary objective of this proposal is to develop a Thoracic Specimen Registry at Mayo Clinic. The purpose of the registry will be to support ongoing research in the etiology, early diagnosis, clinical management, and prognosis of lung cancer and other cancers and diseases of the thorax by developing a complete repository of specimens from patients with thoracic disease including but not limited to suspected lung cancer, mediastinal and pleural tumors and from patients at a very high risk of developing other thoracic cancers or other thoracic diseases. 

9. 3D Ultrasound for the Imaging of Axillary Lymph Nodes in Patients With Breast Cancer

   Rochester, Minn.

   The overall goal of this project is to study a new 3D ultrasound imaging technology for evaluation of axillary lymph nodes in patients with breast cancer.

    

10. Colorectal Cancer Screening in Black and Underserved Communities in the Phoenix Metro Area

    Scottsdale/Phoenix, Ariz.

    The aims of this study are to increase the number of Black consultants at MCA, make a meaningful impact on interactions among staff, leadership, and patients, and increase the number of Black staff in leadership roles beyond Diversity and Inclusion efforts.
