A Study of N9 Chemotherapy in Children With Neuroblastoma
NeuroblastomaPediatric CancerThe purpose of the study is to find out whether N9 is a safe and effective treatment for children with neuroblastoma. N9 includes 3 different combinations of chemotherapy drugs that are given at different times - Cyclophosphamide, topotecan, and vincristine (CTV), Ifosfamide, carboplatin, and etoposide (ICE), Cyclophosphamide, doxorubicin, and vincristine (CDV).
Allogeneic Expanded Gamma Delta T Cells With GD2 Chemoimmunotherapy in Relapsed or Refractory Neuroblastoma...
NeuroblastomaRefractory Neuroblastoma1 moreHigh risk neuroblastoma is an aggressive and often lethal pediatric solid tumor. Survival remains less than 50% and those patients who do survive suffer many treatment-related acute and chronic toxicities. Chemoimmunotherapy using a combination of an anti-GD2 monoclonal antibody (dinutuximab) and different chemotherapy agents in the relapsed/refractory (r/r) neuroblastoma population, has demonstrated the most robust response rates to date, shifting the clinical practice to administer chemoimmunotherapy as a standard treatment for patients with r/r neuroblastoma. The goal of this study is to improve upon GD2 chemoimmunotherapy regimens for neuroblastoma by delivering standard drugs like temozolomide, irinotecan, and dinutuximab in combination with a novel cell-based immunotherapy called gamma delta (γδ) T cells in addition to zoledronate that enhances γδ T cell activation and potency. γδ T cells are an innovative approach to cell therapy for neuroblastoma as they are major histocompatibility complex (MHC) independent and directly cytotoxic to tumor cells without the need for engineering them to recognize the tumor. The study team has developed a Good Manufacturing Practice (GMP)-compliant manufacturing strategy to expand safe γδ T cells from healthy donors for this trial. This is a Phase 1 study to determine the safety, recommended phase 2 dose, and preliminary efficacy of allogeneic (third party), ex vivo expanded γδ T cells in combination with dinutuximab, temozolomide, irinotecan and zoledronate in children with refractory, relapsed, or progressive neuroblastoma.
Immunotherapy With Dinutuximab Beta in Combination With Chemotherapy for the Treatment of Patients...
High-Risk NeuroblastomaSafety evaluation and initial efficacy evaluation will be conducted in a group of patients as a non-commercial, open-label clinical trial of dinutuximab beta (Qarziba) phase IIa. The investigational medicinal product will be dinutuximab beta (anti-GD2 antibodies against GD2 disialoganglioside on NBL cells) at a dose of 10 mg / m2 / day by continuous infusion for 5 days in combination with irinotecan / temozolomide, topotecan / temozolomide or N5 / N6 chemotherapy GPOH protocol. The study group will be patients with recurrent / progression of NBL or disease resistant to first-line treatment, for whom there are currently no standards of management, and the treatment methods used so far do not give a chance to achieve a permanent remission of the disease. After diagnosis of relapse / progression or resistance to treatment, it is permissible to administer 2 cycles of standard chemotherapy prior to enrollment in the study. The study plans to recruit 20 patients who will receive 5-7 cycles of DB with chemotherapy. The choice of an appropriate chemotherapy regimen will depend on the patient's prior treatment and tolerance. The safety assessment will be conducted based on the registration of the types and frequency of adverse reactions identified on the basis of the registration of clinical parameters, symptoms and / or diseases reported by the patient or identified during the intervention and / or follow-up visits, abnormal laboratory and / or imaging test results. The initial assessment of the effectiveness will consist in comparing the percentage of objective responses obtained and the annual EFS and PFS (imaging tests, including scintigraphy, bone marrow examination and tumor markers). The study also included an exploratory evaluation of the usefulness of immunological, genetic and other studies.

A Study of Cabozantinib as a Maintenance Agent to Prevent Progression or Recurrence in High-Risk...
NeuroblastomaSarcomaThis study will expand the types of pediatric cancers being evaluated for response to cabozantinib. The current COG study is restricted to Ewing sarcoma, osteosarcoma, rhabdomyosarcoma, Wilms tumor, and a handful of uncommon tumors. The proposed study will extend this evaluation to tumors that have been shown to either express known targets of cabozantinib or with preclinical evidence of efficacy, including specifically neuroblastomas. These tumors have high morbidity and mortality, particularly in the relapse setting, and few or no proven therapeutic options. As such, evaluation of cabozantinib in these studies is warranted. The study hypothesizes that use of cabozantinib in patients with ultra-high-risk pediatric solid tumors with minimal disease burden, as defined in the inclusion criteria below, can prevent and/or slow recurrent tumor formation in pediatric solid tumors and thereby significantly extend the period of disease control and/or induce a durable cure.
177Lutetium-DOTATATE in Children With Primary Refractory or Relapsed High-risk Neuroblastoma
Neuroblastoma RecurrentNeuroblastomaThe LuDO-N Trial is a multi-centre phase II clinical trial on 177Lu-DOTATATE treatment of recurrent or relapsed high-risk neuroblastoma in children. The LuDO-N Trial builds on the experience from the previous LuDO Trial and utilises an intensified dosing schedule to deliver 2 doses over a 2-week period, in order to achieve a maximal effect on the often rapidly progressing disease. This strategy requires a readiness for autologous stem cell transplantation in all patients, but is not anticipated to increase the risk of long-term sequelae, since the cumulative radiation dose remains unchanged. The primary aim of the study is to assess the response to 177Lu-DOTATATE treatment at 1 and 4 months after ende of treatment. Secondary aims are to assess survival and treatment-related toxicity. Additional aim are to correlate tumour dosimetry with response, correlate SSTR-2 expression with 68Ga-DOTATATE uptake and to correlate the uptake with the treatment response.
Study of Onivyde With Talazoparib or Temozolomide in Children With Recurrent Solid Tumors and Ewing...
Recurrent Solid TumorRecurrent Ewing Sarcoma20 moreThe 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.
Study Of Palbociclib Combined With Chemotherapy In Pediatric Patients With Recurrent/Refractory...
Ewing SarcomaSolid Tumors5 moreA study to learn about safety and find out maximum tolerable dose of palbociclib given in combination with chemotherapy (temozolomide with irinotecan or topotecan with cyclophosphamide) in children, adolescents and young adults with recurrent or refractory solid tumors (phase 1). Neuroblastoma tumor specific cohort to further evaluate antitumor activity of palbociclib in combination with topotecan and cyclophosphamide in children, adolescents, and young adults with recurrent or refractory neuroblastoma. Phase 2 to learn about the efficacy of palbociclib in combination with irinotecan and temozolomide when compared with irinotecan and temozolomide alone in the treatment of children, adolescents, and young adults with recurrent or refractory Ewing sarcoma (EWS).
EGFR806 CAR T Cell Immunotherapy for Recurrent/Refractory Solid Tumors in Children and Young Adults...
Pediatric Solid TumorGerm Cell Tumor14 moreThis 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.
