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. 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.

3. International Penile Advanced Cancer Trial (International Rare Cancers Initiative Study)

   Rochester, Minn.

   This is an international phase III trial, with a Bayesian design, incorporating two sequential randomisations. It efficiently examines a series of questions that routinely arise in the sequencing of treatment. The study design has evolved from lengthy international consultation that has enabled us to build consensus over which questions arise from current knowledge and practice. It will enable potential randomisation for the majority of patients with inguinal lymph node metastases and will provide data to inform future clinical decisions. InPACT-neoadjuvant patients are stratified by disease burden as assessed by radiological criteria. Treatment options are then defined according to the disease burden strata. Treatment is allocated by randomisation. Patients may be allocated to one of three initial treatments: A. standard surgery (ILND); B. neoadjuvant chemotherapy followed by standard surgery (ILND); or C. neoadjuvant chemoradiotherapy followed by standard surgery (ILND). After ILND, patients are defined as being at low or high risk of recurrence based on histological interpretation of the ILND specimen. Patients at high risk of relapse are eligible for InPACT-pelvis, where they are randomised to either: P. prophylactic PLND Q. no prophylactic PLND

4. A Study To Collect Thoracic Specimens To Develop A Thoracic Specimen Registry

   Jacksonville, Fla., 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. 

5. A Study Of Standard Systemic Therapy With Or Without Definitive Treatment In Treating Participants With Metastatic Prostate Cancer

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

   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.

6. Treatment Of Metastatic Soft Tissue Sarcoma (STS) Patients (FIBROSARC USA)

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

   The present study is an open-label, randomized, controlled, two-arm multi-center study of the efficacy of L19TNF treatment in combination with doxorubicin versus doxorubicin alone in metastatic or unresectable soft-tissue sarcoma patients. In the study, 122 patients will be randomized in a 1:1 ratio to receive doxorubicin treatment (Arm 1) or L19TNF treatment in combination with doxorubicin (Arm 2). The primary objective of the trial is to evaluate if L19TNF in combination with doxorubicin (Arm 2) given for unresectable or metastatic soft tissue sarcoma improves efficacy measured as progression free survival, as compared to doxorubicin alone (Arm 1). Anti-cancer activity will be assessed every 6 weeks during therapy and every 12 weeks thereafter.

7. A Study To Evaluate The Feasibility Of Intraoperative Microdialysis (Tissue Sampling) During Neurosurgery For Central Nervous System Malignancies

   Rochester, Minn.

8. Tebentafusp Regimen Versus Investigator's Choice In Previously Treated Advanced Melanoma (TEBE-AM)

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

   The purpose of this study is to evaluate the effectiveness and safety of tebentafusp-based regimens tebentafusp monotherapy and in combination with anti-PD1) vs investigator choice (including clinical trials of investigational agents, salvage therapy per local standard of care (SoC), best supportive care (BSC)) on protocol survivor follow up) in patients with advanced non-ocular melanoma.

9. Trimethoprim-sulfamethoxazole Graded Administration in Oncology, Hematopoietic Stem Cell Transplant, and Solid Organ Transplant Patients with a History of Sulfonamide Allergy

   Rochester, Minn.

   The aim of this study is to study the efficacy and safety of our short and long one-day protocols for TMP-SMX graded administration in hematologic malignancy, hematopoietic stem cell transplant, and solid organ transplant patients.    

10. Effects of Cognitive Function, Post-op Fatigue and Quality of Life Comparing General vs Regional Anesthesia for Non-eloquent Brain Tumors Resection

    Jacksonville, Fla.

    The aim of the study is to create a registry to prospectively collect pre-operative, during surgery and post-operative data, questionaries will assess (at baseline before the surgery, 3-4 weeks, and at 3-6 months) cognitive function, assessed with a Mini-mental State Examination (MMSE), PROMIS Fatigue 7a form, quality of life (QoL), assessed using the SF-12 questionnaire, quality of sleep assessed using PROMIS Sleep disturbance 7a form (1 week after surgery).
