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. 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.

3. Long-Term Follow-Up of Patients Who Have Participated in Children's Oncology Group Studies

   Rochester, Minn.

   This clinical trial is studying long-term follow-up in patients who are or have participated in Children's Oncology Group studies. Developing a way to track patients enrolled in Children's Oncology Group studies will help doctors gather long-term follow-up information and may help the study of cancer in the future.

4. 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.

5. 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.

6. 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.

7. Hypo-fractionated Proton Radiation Therapy With or Without Androgen Suppression for Intermediate Risk Prostate Cancer

   Scottsdale/Phoenix, Ariz.

   The purpose of this study is to compare the effects, good and/or bad of two treatment methods on subjects and their cancer. Proton beam radiation therapy is one of the treatments for men with prostate cancer who have localized disease. The benefit of the combination with androgen suppression is not completely understood. This study will compare the use of hypofraction proton therapy (28 treatments) alone to proton therapy with androgen suppression therapy.

8. 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.

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

    Rochester, Minn., Scottsdale/Phoenix, Ariz.

    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.
