1. A Study of Standard Systemic Therapy with or without Definitive Treatment in Treating Participants with Metastatic Prostate Cancer

   La Crosse, Wis., Rochester, Minn., Scottsdale/Phoenix, Ariz.

   The purpose of this study is to evaouate how well standard systemic therapy with or without definitive treatment (prostate removal surgery or radiation therapy) works in treating participants with prostate cancer that has spread to other places in the body.

2. 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.

3. 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.

4. A Survey of Pheochromocytoma and Paraganglioma Patient Environment

   Rochester, Minn.

   The purpose of this study is to determine the association of environmental, geographic factors, as well as presence of comorbidities associated with hypoxia with development of pheochromocytomas and paragangliomas (PPGL), location of PPGL, and number of PPGL.

    

5. A Study to Evaluate Outpatient Blinatumomab in Subjects with Minimal Residual Disease (MRD) of B-precursor Acute Lymphoblastic Leukemia (ALL)

   Jacksonville, Fla.

   The purpose of this study is to determine the safety and feasibility of complete outpatient blinatumomab administration for subjects with minimal residual disease (MRD) of B-precursor Acute Lymphoblastic Leukemia (ALL).

    

    

6. Early pancreatic cancer detection

   Jacksonville, Fla.

   The primary purpose of this study is to standardize the collection of demographic, clinical, and imaging data, and biosamples for a large high-risk familial Pancreatic Ductal Adenocarinoma (PDAC) cohort at consortium clinical cancer centers, worldwide.

7. 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

8. 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.

9. 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. 

10. A Study to Evaluate Individualized Prehabilitation for People Undergoing Neo-Adjuvant Radiotherapy and Lower Limb Soft-Tissue Sarcoma Surgery

    Scottsdale/Phoenix, Ariz.

    The primary objectives of this study are to determine if a tailored prehabilitation program focusing on functional optimization of spared limb tissue in two groups of patients with localized, lower extremity soft tissue sarcoma, one with prehabilitation and one with equal attention and informational support, improves functional outcome as measure by the Toronto Extremity Salvage Score (TESS), to identify the measures and metrics most responsive to the intervention using the (TESS), Six Minute Walk Test (6MWT)[5], wearable Heel2Toe sensor technology and daily step count, and to estimate recruitment, retention, adherence, and acceptability rates.
