B7H3 CAR T Cell Immunotherapy for Recurrent/Refractory Solid Tumors in Children and Young Adults

This is a phase I, open-label, non-randomized study that will enroll pediatric and young adult research participants with relapsed or refractory non-CNS solid tumors to evaluate the safety, feasibility, and efficacy of administering T cell products derived from the research participant's blood that have been genetically modified to express a B7H3-specific receptor (chimeric antigen receptor, or CAR) that will target and kill solid tumors that express B7H3. On Arm A of the study, research participants will receive B7H3-specific CAR T cells only. On Arm B of the study, research participants will receive CAR T cells directed at B7H3 and CD19, a marker on the surface of B lymphocytes, following the hypothesis that CD19+ B cells serving in their normal role as antigen presenting cells to T cells will promote the expansion and persistence of the CAR T cells. Arm A CAR T cells include the protein EGFRt and Arm B CAR T cells include the protein HER2tG. These proteins can be used to both track and destroy the CAR T cells in case of undue toxicity. The primary objectives of the study will be to determine the feasibility of manufacturing the cell products, the safety of the T cell product infusion, to determine the maximum tolerated dose of the CAR T cells products, to describe the full toxicity profile of each product, and determine the persistence of the modified cell in the participant's body on each arm. Participants will receive a single dose of T cells comprised of two different subtypes of T cells (CD4 and CD8 T cells) felt to benefit one another once administered to the research participants for improved potential therapeutic effect. The secondary objectives of this protocol are to study the number of modified cells in the patients and the duration they continue to be at detectable levels. The investigators will also quantitate anti-tumor efficacy on each arm. Participants who experience significant and potentially life-threatening toxicities (other than clinically manageable toxicities related to T cells working, called cytokine release syndrome) will receive infusions of cetuximab (an antibody commercially available that targets EGFRt) or trastuzumab (an antibody commercially available that targets HER2tG) to assess the ability of the EGFRt on the T cells to be an effective suicide mechanism for the elimination of the transferred T cell products.

Uptake and Biodistribution of 89Zirconium-labeled Ipilimumab in Ipilimumab Treated Patients With Metastatic Melanoma

Rationale: Ipilimumab, a monoclonal antibody targeting CTLA-4, is approved for the treatment of metastatic melanoma and significantly increases median overall survival. However, use of this drug is associated with immune related adverse events (IRAEs) like colitis, hepatitis, dermatitis, alveolitis and hypophysitis in 10-40% of the patients. In general IRAEs are manageable by cessation of ipilimumab in combination with treatment with corticosteroids or TNF-alpha blockade but they can be severe or even life-threatening. In addition, treatment with ipilimumab is expensive. Because of the high costs and the potential serious toxicity of ipilimumab, it is of great importance to identify biomarkers that correlate with clinical activity and can be used to select patients that will benefit from CTLA-4 blockade therapy. The investigators hypothesize that differences in response to treatment with ipilimumab are due to variability in the pharmacodynamics and -kinetics of the antibody. It is hypothesized that patients who do not respond to treatment with ipilimumab have lower drug levels in tumor tissues as compared to patients with a good response to therapy. In addition, the investigators hypothesize that IRAEs are associated with high drug levels in the affected tissue. To visualize molecular interactions a novel technique is used in which positron emission tomography (PET) is combined with labeled monoclonal antibodies. Because ipilimumab induces activation of T-lymphocytes it is hypothesized that uptake of 89Zr-ipilimumab in tumor lesions and normal tissue is different (i.e. higher) after the second administration of ipilimumab (3 weeks after first injection). Therefore immuno-PET scans will be performed after the first and after the second injection of ipilimumab. Objective: Part one: The primary objective is: 1. To assess uptake (visual and quantitative) of 89Zr-ipilimumab in tumor lesions and biodistribution at two timepoints (at start of ipilimumab therapy and after the second injection 3 weeks later). The secondary objectives are: To determine the correlation between tumor targeting of ipilimumab and response to therapy. To assess uptake (visual and quantitative) of 89Zr-ipilimumab in normal tissues. To determine de correlation between organ targeting and toxicity

Study of TBI-1301 (NY-ESO-1 Specific TCR Gene Transduced Autologous T Lymphocytes) in Patients With Solid Tumors

The target populations for this phase I study with TBI-1301 are patients with advanced solid tumors. Patients' tumors will be required to express NY-ESO-1, which include but is not limited to ovarian cancer, synovial sarcoma, esophageal cancer, lung cancer, bladder cancer, liver cancer, and malignant melanoma. Patients must be positive for HLA-A*02:01 or HLA-A*02:06 and the patient's tumor tissue must be positive for NY-ESO-1 antigen expression. The study will take the subject's T cells, which are a natural type of immune cell in the blood, and send them to a laboratory to be modified. The changed T cells used in this study will be the subject's own T cells that have been genetically changed with the aim of attacking and destroying cancer cells. The manufacturing of T cells takes about 1 month to complete. The T cells will be given back to the subject through an intravenous infusion. The purpose of this study is to test the safety of genetically changed T cells and find out what effects, if any, they have in subjects with advanced solid tumors. The purpose of this study is to evaluate the safety profile of TBI-1301, to determine the recommended phase 2 (RP2D) dose of TBI-1301 when administered following cyclophosphamide and fludarabine pre-treatment, to evaluate the safety of repeat dosing of TBI-1301, to assess the presence/absence of RCR appearance after TBI-1301 infusion, to assess the presence or absence of clonality by LAM-PCR, and to evaluate evidence of efficacy of TBI-1301 using RECIST v1.1.
