Filter by:The purpose of this study is to test the feasibility (ability to be done) of experimental technologies to determine a tumor's molecular makeup. This technology includes a genomic report based on DNA exomes and RNA sequencing that will be used to discover new ways to understand cancers and potentially predict the best treatments for patients with cancer in the future.
Hu14.18K322A is a monoclonal antibody developed at St. Jude Children's Research Hospital (SJCRH) that is made to bind to cancer cells that have a molecule called GD2 on their surface. Sometimes the human body will make an antibody to the therapeutic antibody (like hu14.18K322A) that is being given for treatment. These are called human anti-human antibodies (HAHA). When testing for HAHA in a previous cohort of patients who received hu14.18K322A, it was found that some patients tested positive for high levels of an antibody before receiving hu14.18K322A or any other anti-GD2 antibody. In this study, investigators would like to know more about the nature of this pretreatment antibody, how often is it present, and if in the laboratory it increases the killing of tumor cells. OBJECTIVES: - To determine whether pretreatment anti-therapeutic antibodies (PATA) represent antibodies reactive against an epitope (allotypic determinant) found on the anti-GD2 antibody hu14.18K322A - To determine if PATA increases the anti-tumor efficacy of anti-GD2 antibodies in vitro
The purpose of this study is to identify phenotypic (cell surface receptor expression) and functional differences in monocyte populations in humans with osteosarcoma as compared to published historical data on normal human monocyte values. The biologic similarity between canine and human osteosarcoma makes it a disease model that holds promise for translational research possibilities. The phenotypic and functional differences the investigators expect to find in canine and human monocytes between normal and osteosarcoma subjects in this pilot work will allow us to launch a program of investigations to further their understanding as to what characteristics are associated with improved survival in canine and human osteosarcoma. Such data will represent the foundation upon which the investigators can plan future investigations designed to exploit the potential anti-tumor capabilities of monocytes and macrophages in canine and human osteosarcoma.
Background GD2 is a well-characterized tumor antigen in neuroblastoma, which is also expressed on osteosarcomas and some other sarcomas. T cells expressing 1st generation anti-GD2 chimeric antigen receptors (CARs) were safe and mediated modest antitumor activity in some patients with refractory neuroblastoma. A 3rd generation anti-GD2-CAR (GD2-CAR.OX40.28.z.ICD9) has been produced and holds promise for increased activity compared to the 1st generation GD2-CAR already studied in clinical trials. As an added safety measure, the vector includes a suicide switch comprising a caspase dimerization domain (ICD9) that can be activated by a small molecule to induce death of the genetically engineered cells if they were induce untoward toxicity. Objectives Primary:Determine the feasibility of producing anti GD2-CAR cells meeting the established release criteria and to assess the safety of administering escalating doses of anti-GD2-CAR engineered T cells in children and young adults with GD2+ solid tumors, including neuroblastoma, following cyclophosphamide-based lymphodepletion. Secondary: 1. Determine if administration anti-GD2-CAR engineered T cells mediate antitumor effects in children and young adults with GD2+ solid tumors; 2. Measure persistence of adoptively transferred anti-GD2-CAR T cells and correlate this with antitumor effects; 3. Extend information regarding the prevalence and intensity of GD2 expression in non-neuroblastoma, non-osteosarcoma solid tumors in children and young adults; 4. If unacceptable toxicity occurs that is possibly, probably or likely related to anti-GD2-CAR T cells, assess the capacity for AP1903, a dimerizing agent, to mediate clearance of the genetically engineered cells and resolve toxicity; and 5. Assess toxicity of AP1903 if administered to mediate clearance of anti-GD2-CAR T cells. Eligibility Patients 1-35 years of age, at least 15 kg, with osteosarcoma or a GD2+ solid tumor (including neuroblastoma) that has recurred after or not responded to standard therapy and is deemed incurable by standard therapy. Design After apheresis to collect T cells for transduction, patients receive cyclophosphamide 1800mg/m(2)/d as a lymphodepleting regimen. A phase I cell dose escalation scheme will used at 4 dose levels (1 x 10(5) transduced T cells/kg; 1 x 10(6) transduced T cells/kg; 3 x 10(6) transduced T cells/kg; and 1 x 10(7) transduced T cells/kg), using a standard 3 plus 3 dose escalation design. An expanded group of a total of 12 patients will be treated at the highest dose, comprising at least 6 osteosarcoma patients. Patients will be monitored for toxicity, antitumor effects and persistence of anti-GD2-CAR T cells. Patients with a PR, SD may receive a 2nd cycle at the next higher dose level a minimum of 60 days following completion of the first cycle if eligibility criteria are met. A maximum of 36 patients may be treated on this study. Given that there is likelihood that some patients with non-osteosarcoma will not meet the criteria for GD2 expression to be eligible for enrollment, up to 72 subjects will be screened to enroll a maximum of 36 patients for treatment. Up to 2-3 patients will be accrued per month, and therefore this study may require up to 2-3 years to complete enrollment and treatment.
The investigators hypothesize that this Phase 2 cellular and adoptive immunotherapy study using human leukocyte antigen (HLA)-haploidentical hematopoietic cell transplantation (HCT) followed by an early, post-transplant infusion of donor natural killer (NK) cells on Day +7 will not only be well-tolerated in this heavily-treated population (safety), but will also provide a mechanism to treat high-risk solid tumors, leading to improved disease control rate (efficacy). Disease control rate is defined as the combination of complete (CR) and partial (PR) response and stable disease (SD). The investigators further propose that this infusion of donor NK cells will influence the development of particular NK and T cell subtypes which will provide immediate/long-term tumor surveillance, infectious monitoring, and durable engraftment. Patients with high-risk solid tumors (Ewings Sarcoma, Neuroblastoma and Rhabdomyosarcoma) who have either measurable or unmeasurable disease and have met eligibility will be enrolled on this trial for a goal enrollment of 20 patients over 4 years.
This phase II trial studies how well eribulin mesylate works in treating patients with osteosarcoma that has come back after treatment (recurrent) or has not responded to treatment (refractory). Microtubule inhibitors, such as eribulin mesylate, may stop or slow the growth of tumor cells by disrupting the cell cycle.
Cisplatin is a key chemotherapy agent for the treatment of multiple childhood cancers but causes permanent hearing loss. This study investigates the drug N-acetylcysteine (NAC) to determine the dose necessary to protect hearing and also how well tolerated NAC is when combined with chemotherapy.
Although regorafenib was approved for use in patients who had progressive GIST despite imatinib and/or sunitinib on the basis of phase II and phase III data, it has not been examined in a systematic fashion in patients with other forms of sarcoma. Given the activity of sorafenib, sunitinib and pazopanib in soft tissue sarcomas, and evidence of activity of sorafenib in osteogenic sarcoma and possibly Ewing/Ewing-like sarcoma, there is precedent to examine SMOKIs (small molecule oral kinase inhibitors) such as regorafenib in sarcomas other than GIST. It is also recognized that SMOKIs (small molecule oral kinase inhibitors)such as regorafenib, sorafenib, pazopanib, and sunitinib have overlapping panels of kinases that are inhibited simultaneously. While not equivalent, most of these SMOKIs (small molecule oral kinase inhibitors) block vascular endothelial growth factor and platelet derived growth factors receptors (VEGFRs and PDGFRs), speaking to a common mechanism of action of several of these agents.
An open-label, multicenter, phase I/II clinical trial to identify the [6R] 5,10-methylenetetrahydrofolate (arfolitixorin) dose with most favorable safety prospect and confirmed ability to mitigate high-dose methotrexate induced toxicity during treatment of osteosarcoma patients
The purpose of this study is to find the safe dose of nab-paclitaxel in children with solid tumors, and to see if it works to treat these solid tumors in children and young adults (in Phase 1 ≤ 18 years old and in Phase 2 ≤ 24 years old). After the final dose has been chosen, patients will be enrolled according to the specific solid tumor type, (neuroblastoma, rhabdomyosarcoma, or Ewing's sarcoma), to see how nab-paclitaxel works in treating these tumors.
