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. 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.

    

3. A Study To Evaluate Combination Therapy To Treat Newly-diagnosed Diffuse Anaplastic Wilms Tumors And Relapsed Favorable Histology Wilms Tumors A Study Of Combination Chemotherapy For Patients With Newly Diagnosed DAWT And Relapsed FHWT

   Rochester, Minn.

   The purpose of this study is to evaluate how well combination chemotherapy works in treating patients with newly diagnosed stage II-IV diffuse anaplastic Wilms tumors (DAWT) or favorable histology Wilms tumors (FHWT) that have come back (relapsed). Drugs used in chemotherapy regimens such as UH-3 (vincristine, doxorubicin, cyclophosphamide, carboplatin, etoposide, and irinotecan) and ICE/Cyclo/Topo (ifosfamide, carboplatin, etoposide, cyclophosphamide, and topotecan) work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading.

   This trial may help doctors find out what effects, good and/or bad, regimen UH-3 has on patients with newly diagnosed DAWT and standard risk relapsed FHWT (those treated with only 2 drugs for the initial WT) and regimen ICE/Cyclo/Topo has on patients with high and very high risk relapsed FHWT (those treated with 3 or more drugs for the initial WT).

4. A Study To Evaluate Bleomycin, Carboplatin, Etoposide, Or Cisplatin In Treating Pediatric And Adult Patients With Germ Cell Tumors

   Rochester, Minn.

   The purpose of this study is to evaluate how well bleomycin, carboplatin, etoposide, or cisplatin work in treating pediatric and adult patients with germ cell tumors. Active surveillance may help doctors to monitor subjects with low risk germ cell tumors after their tumor is removed. Drugs used in chemotherapy, such as bleomycin, carboplatin, etoposide, and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading.

5. 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.

6. Personalized Neoantigen Peptide-Based Vaccine In Combination With Pembrolizumab For Treatment Of Advanced Solid Tumors

   Jacksonville, Fla.

   This phase I/II trial tests the safety and tolerability of an experimental personalized vaccine when given by itself and with pembrolizumab in treating patients with solid tumor cancers that have spread to other places in the body (advanced). The experimental vaccine is designed target certain proteins (neoantigens) on individuals' tumor cells. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving the personalized neoantigen peptide-based vaccine with pembrolizumab may be safe and effective in treating patients with advanced solid tumors.

7. A Study to See if the Depth of Tumor Invasion of Esophageal Carcinoma Predicts Lymph Node Involvement and Cancer Free Survival

   Rochester, Minn.

   The purpose of this study is to see if different depths of submucosal tumor invasion in esophageal cancer can predict lymph node involvement and survival.

8. A Study To Evaluate Personalized Molecular Marker And Immunoprofiling To Transform Hepatocellular Carcinoma Treatment

   Jacksonville, Fla.

   The purpose of this study is to evaluate whether profiling aggressive tumors for molecular alterations, together with drug testing in patient-derived 3D models, can provide crucial information for the identification of specific therapeutic targets. Additionally, immunoprofiling of microcancer model systems is crucially necessary data to enable prediction of immunotherapeutic efficacy. We postulate that our innovative approach will establish much needed immune microenvironment information and facilitate the identification of specific sensitivity profiles and biomarker signatures that correlate response to targeted agents (or combinations) with particular tumor profiles.

9. Comparing Rituximab And Mosunetuzumab Drug Treatments For People With Low Tumor Burden Follicular Lymphoma

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

   The purpose of this study is to compare the effectiveness of rituximab to mosunetuzumab in treating patients with follicular lymphoma with a low tumor burden. Rituximab is a monoclonal antibody. It binds to a protein called CD20, which is found on B cells (a type of white blood cell) and some types of cancer cells. This may help the immune system kill cancer cells. Mosunetuzumab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. It is not yet known if giving rituximab or mosunetuzumab works better in treating patients with follicular lymphoma with a low tumor burden.

10. Testing The Addition Of Duvelisib Or CC-486 To The Usual Treatment For Peripheral T-Cell Lymphoma

    Rochester, Minn.

    The purpose of this study is to evaluate the effect of duvelisib or CC-486 and usual chemotherapy consisting of cyclophosphamide, doxorubicin, vincristine, etoposide, and prednisone in treating patients with peripheral T-cell lymphoma. Duvelisib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Chemotherapy drugs, such as CC-486, cyclophosphamide, doxorubicin, vincristine, etoposide and prednisone, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. This trial may help find out if this approach is better or worse than the usual approach for treating peripheral T-cell lymphoma.
