Effects of Maintenance Cabozantinib+BSC Versus BSC in Children and AYA With Osteosarcoma
Description

The participants of this study will be children, adolescents, and young adults with residual osteosarcoma, which cannot be removed completely through surgery. Participants will have achieved a partial response or stable disease at the end of conventional chemotherapy. Osteosarcoma is cancer of the bone. The cancer cells make immature bone cells, known as osteoid. Osteosarcoma is very rare, but it is the most common type of bone cancer in children and teens. It is most common in teens and young adults. In this study, participants will receive either cabozantinib and best supportive care or the best supportive care alone. Best supportive care will be provided at the investigator's discretion and according to institutional guidelines. It includes antibiotics, nutritional support, correction of metabolic disorders, optimal symptom control and pain management (including radiotherapy), etc. but does not include tumor specific therapy. Cabozantinib will be taken by mouth (orally), as a tablet, once a day. Cabozantinib will be provided to participants who tolerate it for as long as their disease does not progress. Participants in the study receiving best supportive care alone may switch to treatment with cabozantinib and best supportive care if their disease progresses and if other eligibility criteria are met. Participants may withdraw consent to participate at any time. The estimated duration of the study for participants is 24 months, however a participant could remain in the study longer if demonstrating treatment benefit.

Study of Onivyde With Talazoparib or Temozolomide in Children With Recurrent Solid Tumors and Ewing Sarcoma
Description

The phase I portion of this study is designed for children or adolescents and young adults (AYA) with a diagnosis of a solid tumor that has recurred (come back after treatment) or is refractory (never completely went away). The trial will test 2 combinations of therapy and participants will be randomly assigned to either Arm A or Arm B. The purpose of the phase I study is to determine the highest tolerable doses of the combinations of treatment given in each Arm. In Arm A, children and AYAs with recurrent or refractory solid tumors will receive 2 medications called Onivyde and talazoparib. Onivyde works by damaging the DNA of the cancer cell and talazoparib works by blocking the repair of the DNA once the cancer cell is damaged. By damaging the tumor DNA and blocking the repair, the cancer cells may die. In Arm B, children and AYAs with recurrent or refractory solid tumors will receive 2 medications called Onivyde and temozolomide. Both of these medications work by damaging the DNA of the cancer call which may cause the tumor(s) to die. Once the highest doses are reached in Arm A and Arm B, then "expansion Arms" will open. An expansion arm treats more children and AYAs with recurrent or refractory solid tumors at the highest doses achieved in the phase I study. The goal of the expansion arms is to see if the tumors go away in children and AYAs with recurrent or refractory solid tumors. There will be 3 "expansion Arms". In Arm A1, children and AYAs with recurrent or refractory solid tumors (excluding Ewing sarcoma) will receive Onivyde and talazoparib. In Arm A2, children and AYAs with recurrent or refractory solid tumors, whose tumors have a problem with repairing DNA (identified by their doctor), will receive Onivyde and talazoparib. In Arm B1, children and AYAs with recurrent or refractory solid tumors (excluding Ewing sarcoma) will receive Onivyde and temozolomide. Once the highest doses of medications used in Arm A and Arm B are determined, then a phase II study will open for children or young adults with Ewing sarcoma that has recurred or is refractory following treatment received after the initial diagnosis. The trial will test the same 2 combinations of therapy in Arm A and Arm B. In the phase II, a participant with Ewing sarcoma will be randomly assigned to receive the treatment given on either Arm A or Arm B.

SUSPENDED
Testing a New Immune Cell Therapy, GD2-Targeted Modified T-cells (GD2CART), in Children, Adolescents, and Young Adults With Relapsed/Refractory Osteosarcoma and Neuroblastoma, The GD2-CAR PERSIST Trial
Description

This phase I trial investigates the side effects and determines the best dose of an immune cell therapy called GD2CART, as well as how well it works in treating patients with osteosarcoma or neuroblastoma that has come back (relapsed) or does not respond to treatment (refractory). T cells are infection fighting blood cells that can kill tumor cells. The T cells given in this trial will come from the patient and will have a new gene put in them that makes them able to recognize GD2, a protein on the surface of tumor cells. These GD2-specific T cells may help the body's immune system identify and kill GD2 positive tumor cells.

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

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.

EGFR806 CAR T Cell Immunotherapy for Recurrent/Refractory Solid Tumors in Children and Young Adults
Description

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 EGFR-specific receptor (chimeric antigen receptor, or CAR) that will target and kill solid tumors that express EGFR and the selection-suicide marker EGFRt. EGFRt is a protein incorporated into the cell with our EGFR receptor which is used to identify the modified T cells and can be used as a tag that allows for elimination of the modified T cells if needed. On Arm A of the study, research participants will receive EGFR-specific CAR T cells only. On Arm B of the study, research participants will receive CAR T cells directed at EGFR 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. The CD19 receptor harbors a different selection-suicide marker, HERtG. 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 subject's body on each arm. Subjects 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. Subjects 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.

Activated T Cells Armed With GD2 Bispecific Antibody in Children and Young Adults With Neuroblastoma and Osteosarcoma
Description

Previous research has demonstrated that investigators can coat (arm) T cells with a special molecule called GD2 bispecific antibody that will help T cells recognize neuroblastoma and osteosarcoma cells and kill them. This bispecific antibody recognizes GD2, a protein found on almost all neuroblastoma and osteosarcoma cells. The investigators put the GD2 bispecific antibody on T cells and give large numbers of these T cells back to patients. The investigators think that these T cells may have a better chance of killing GD2 expressing tumor cells when they are armed with GD2 bispecific antibody. This trial studies the side effects and best dose of activated T cells armed with GD2 bispecific antibody and how well they work in treating patients with neuroblastoma, osteosarcoma, and other GD2-positive solid tumors.

COMPLETED
A Phase I Trial of T Cells Expressing an Anti-GD2 Chimeric Antigen Receptor in Children and Young Adults With GD2+ Solid Tumors
Description

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.

Study of Fixed vs. Flexible Filgrastim to Accelerate Bone Marrow Recovery After Chemotherapy in Children With Cancer
Description

This randomized phase III trial studies flexible administration of filgrastim after combination chemotherapy to see how well it works compared to fixed administration of filgrastim in decreasing side effects of chemotherapy in younger patients with cancer. Cancer chemotherapy frequently results in neutropenia (low blood counts) when patients are susceptible to severe infections. A medicine called G-CSF (filgrastim) stimulates bone marrow and daily filgrastim shots are commonly used to shorten neutropenic periods and decrease infections after chemotherapy. Since filgrastim is customarily used on a fixed schedule starting early after chemotherapy and there are data that early doses may not be needed, this study tests new flexible schedule of filgrastim to optimize its use by reducing the number of painful shots, cost of treatment, and filgrastim side effects in children with cancer receiving chemotherapy.

A Phase I Study of Pazopanib as a Single Agent for Children With Refractory Solid Tumors
Description

Background: - Pazopanib, a drug that inhibits the growth of new blood vessels in tumors, was recently approved by the Food and Drug Administration to treat advanced kidney cancer in adults. Pazopanib has been used in only a small number of adults, and more research is needed on whether it is safe and effective to use in children. Researchers are interested in determining safe and effective treatment doses of pazopanib in children, and in other studies will examine which form of pazopanib treatment (tablet or liquid) is most effective and well tolerated. Objectives: * To determine a safe and effective dose of pazopanib to treat solid tumors in children. * To study the effects of pazopanib on blood cells, blood flow, and human development. Eligibility: - Children, adolescents, and young adults between 1 and 21 years of age who have been diagnosed with solid tumors that have not responded to treatment. Design: * Eligible participants will be screened with a physical examination, blood and tumor samples, and imaging studies. * Participants will receive pazopanib tablets for 28-day cycles of treatment. Pazopanib should be taken on an empty stomach, at least 1hour before or 2 hours after a meal. Participants may receive pazopanib for up to 24 cycles unless the tumor does not respond or participants develop serious side effects. * Blood samples will be taken on days 1, 15, 22, and 27 of the first cycle of pazopanib, with additional samples taken every 8 weeks during subsequent cycles. * An optional part of the study will collect additional blood samples at regular intervals for 24 hours after the first dose of pazopanib and at regular intervals after another dose during the second or third week of the first treatment cycle.

TERMINATED
HGS-ETR2 to Treat Children With Solid Tumors
Description

Background * HGS-ETR2 is a monoclonal antibody, produced in the laboratory from human genes. * HGS-ETR2 targets a protein called the TRAIL receptor that is located on the surface of some tumor cells. When the TRAIL receptor is activated, it can cause the tumor cell to self-destruct. Objectives: * To determine the highest dose of HGS-ETR2 that can be given safely in children and young adults with cancer. * To study the pharmacology (how the body handles the drug) of HGS-ETR2 by measuring the amount of drug in the bloodstream over time before and after a dose is given to the patient. * To determine if HGS-ETR2 can stop or slow tumor growth. * To determine whether proteins in tumor tissue before treatment can predict whether the tumor will respond to HGS-ETR2 therapy. Eligibility: -Patients 1 to 21 years of age with solid cancers that do not respond to standard therapy. Design: * HGS-ETR2 is given through a vein (intravenously, IV) once every 14 days. Each treatment cycle is 28 days long and consists of two doses of HGS-ETR2. * The dose of HGS-ETR2 is increased in successive small groups of patients until the maximum tolerated dose (highest dose with acceptable side effects) is determined. * During the treatment period, patients have a physical examination at least once a week, and routine blood tests at least twice a week. These tests are done less frequently in later treatment cycles. * Additional blood samples are drawn for immunology and pharmacology studies. * Tests to monitor the size of the tumor (X-rays, CT scans, MRI, PET scans) are done periodically throughout the treatment period. * Patients may continue to receive HGS-ETR2 until unacceptable side effects develop or the tumor grows.

Recombinant Human Thrombopoietin in Children Receiving Ifosfamide, Carboplatin, and Etoposide Chemotherapy
Description

Life-threatening thrombocytopenia (low platelet count) and neutropenia (low white blood count) remain the major dose-limiting toxicities following chemotherapy treatment for cancer. The only remedy for thrombocytopenia at present is platelet transfusion, which is effective in preventing life-threatening hemorrhage, but may lead to other complications. Preclinical studies and studies in adults have shown recombinant human thrombopoietin (rhTPO) to be effective in stimulating platelet production. The initial phase of this trial will evaluate the safety of rhTPO use immediately after chemotherapy with ifosfamide, carboplatin, and etoposide in children with solid tumors and lymphomas. The second phase of the study will evaluate the effectiveness of rhTPO in decreasing the duration of low platelet count after chemotherapy.
