1. 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.

2. 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.

3. 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.

4. 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.

5. 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.

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. 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.

8. Prospective Use Of Philips ISuite For Interventional Procedures

   Rochester, Minn.

   This research study is being done to look at new MRI imaging guidance software, Philips Interventional iSuite software, to see if using will improve the physician's ability to quickly place and guide needle tip position for biopsies and ablations.

9. 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

10. Establishment Of Preclinical Models From Patients With Gynecological Malignancies

    Scottsdale/Phoenix, Ariz., Rochester, Minn.

    Effective treatments for recurrent gynecological cancer are lacking, and there is a need for novel therapeutic options. One of the barriers to improving outcomes in this subgroup of patients is the paucity of tumor models that can mimic patient characteristics to study novel therapies. Patient-derived xenograft (PDX) models are considerate the most representative pre-clinical model of human cancer, recapitulating the key characteristics of the original patient tumor. Other preclincal models to test drug effcicacy includes ex vivo 3D culture and 2D culture systems. In this study, we make and test preclinical models of gynecological cancers (ovarian, fallopian tube, peritoneal, uterine, vulvar, cervix, and vaginal) of any histologic subtype using surplus tumor specimens obtained at the time of routine tumor biopsy procedure, or clinically-indicated surgery.
