Relapsed Neuroblastoma

The purpose of this study is to find the largest safe dose of i15.NKG2D.zeta-NK cells in combination with C7R.GD2.CAR-T cells, and additionally to evaluate how long they can be detected in patients' blood and what affect they have on patients' cancer. Patients eligible for this study have neuroblastoma or osteosarcoma that expresses a substance on the cancer cells called GD2. This cancer has either come back after treatment or did not respond to the standard or other investigational treatments or therapies used to treat it. There is no standard treatment for these types of advanced cancers at this time. This is a gene transfer research study using special immune cells called NK cells and T cells. NK cells and T cells are types of white blood cell that help the body fight infection. The body has different ways of fighting infection and disease. No single way seems perfect for fighting cancers. This research study combines two different ways of fighting cancer: NK cells and T cells. T cells are special infection-fighting blood cells that can kill cells infected with viruses and tumor cells. NK cells, another kind of infection-fighting cell, can recognize a wide range of cells in distress, including tumor cells and cells that help protect tumor cells in the cancer environment. Both NK cells and T cells have been used individually to treat patients with cancers. They have shown promise, but have not been strong enough individually to cure most patients. Investigators have found from previous research that we can put a new gene into T cells that will make them recognize GD2, a substance found on almost all neuroblastoma and osteosarcoma cells. We can also put a new gene into NK cells that help them fight the tumor environment. Investigators know that T cells and NK cells need substances called cytokines to survive but the cells do not get enough cytokines after infusion into the body; therefore, the investigators have added the genes C7R and IL15 into the T and NK cells, respectively, to give each cell a constant supply of cytokine that helps them to survive longer. The C7R.GD2.CAR-T cells and i15.NKG2D.zeta-NK cells are investigational products not approved by the Food and Drug Administration.

The phase 1 primary objective is to determine the pediatric recommended phase 2 dose (RP2D) of PEEL-224 as a single agent (phase 1A) and in combination with vincristine and temozolomide (phase 1B). The phase 2 primary objective is to estimate the objective response rate (ORR) in children with refractory, progressive and relapsed NBL and rhabdomyosarcoma (RMS) treated with the RP2D of PEEL-224 in combination with vincristine and temozolomide.

This illustrative Phase 1/Phase 2 study tests allogeneic dual-target GD2/B7-H3 (CD276) CAR-NK cells in children and young adults with relapsed or refractory neuroblastoma. After lymphodepletion, participants receive IV CAR-NK cells;Part A defines the RP2D and Part B estimates preliminary activity

Neuroblastoma is one of the most common solid childhood tumours, and a major cause of cancer-related death in children. More than 1200 children/young adults a year are diagnosed in USA and Europe. Around 600 of these cases are considered high-risk, which means the cancer is more difficult to treat successfully. Despite improvements in survival over recent decades, a significant proportion of patients with high-risk neuroblastoma have disease that does not respond to standard treatments (refractory neuroblastoma) or comes back after completion of standard frontline treatment (relapsed neuroblastoma). Therefore, there is a need to develop new treatment strategies and test new drugs to improve outcomes for children with neuroblastoma. Aims Of The BEACON2 Trial * To improve survival for patients with relapsed neuroblastoma by developing new treatment combinations * To evaluate new treatment combinations in relapsed neuroblastoma, within a phase I/II trial that can impact clinical practice, while also allowing dose confirmation for new promising combinations * To evaluate the safety, activity, efficacy and impact on quality of life of these new treatment combinations in relapsed neuroblastoma patients * To improve our understanding of relapsed neuroblastoma biology and advance the development of targeted therapies using biomarkers, by conducting a comprehensive biomarker sample collection. Trial Design BEACON2 is a randomised phase I/phase II, open label, international trial. The trial will have two tiers: Tier 1 will be the main randomisation for two treatment arms initially. Participants will be randomised at trial entry to receive one of the available regimens, treatment A or treatment B. Tier 2 will include smaller dose expansion/confirmation cohorts for more novel experimental treatment combinations (Arm C and future arms), with the potential for them to be moved to Tier 1. Current Tier 1 (Randomisation Tier) Treatment Arms in the BEACON2 Trial: Arm A: dbIT Treatment with dinutuximab beta, irinotecan, and temozolomide, 3 weekly x12 cycles Arm B: BIT Treatment with bevacizumab, irinotecan, and temozolomide, 3 weekly x12 cycles Current Tier 2 (Registration Only Tier) Treatment Arms in the BEACON2 Trial: Arm C: dbBIT Treatment with dinutuximab beta, bevacizumab, irinotecan, and temozolomide, 3 weekly x12 cycles Patient Population and Sample Size Patients aged ≥1 years of age with relapsed neuroblastoma. For each arm in Tier 1, up to 75 patients will be recruited to complete phase 2 investigations. For each arm in Tier 2, 10 patients will be recruited to complete phase I investigations. Approximately 160 participants are initially planned, 75 in each arm of Tier 1 and 10 participants for one dose-confirmation cohort in Tier 2. The study is expected to recruit patients for 3 years, and then finish patient follow-up after an additional 5 years. Translational Sub-study / Biological Studies It is standard of care for patients diagnosed with relapsed neuroblastoma to: * Have had a tumour sample collected at point of initial diagnosis (either during biopsy or surgery) * Have bloods collected before they start and during treatment for their relapsed neuroblastoma * Have a bone aspirate/trephine procedure in order to help confirm relapse. These samples provide very important opportunities for further research, and the study investigators would like to make full use of these opportunities by collecting the analysis already performed on these samples and collect some additional samples (at the same time as the standard ones) to learn and understand more about neuroblastoma and its treatment. Samples will undergo research analysis at the national SIOPEN reference laboratories.

This Phase 1/2 trial aims to determine the safety and feasibility of administration of autologous chimeric antigen receptor (CAR) T cells targeting the human Anaplastic Lymphoma Kinase (ALK) receptor in pediatric subjects with relapsed or refractory neuroblastoma (NB). The trial will be conducted in two phases: Phase 1 will determine the maximum tolerated dose (MTD) of autologous hALK.CAR T cells using a 3+3 dose escalation design. Phase 2 will be an expansion phase to determine rates of response to hALK.CAR T cells.

This is a first in human dose escalation trial to determine the safety of administering GPC2 CAR T cells in patients with advanced neuroblastoma or retinoblastoma.

The goal of this clinical trial is to determine the maximum tolerated dose (MTD) and recommended Phase II dose (RP2D) of allogeneic expanded γδ T cells when delivered with Dinutuximab, temozolomide, irinotecan, and zoledronate in children with refractory or recurrent neuroblastoma or refractory/ relapsed osteosarcoma as well as to define the toxicities of allogeneic expanded γδ T cells when delivered with Dinutuximab, temozolomide, irinotecan, and zoledronate

This research is being done to investigate a treatment regimen of Irinotecan, Temozolomide, and Sargramostin, and an immunotherapy called Naxitamab and whether giving Naxitamab more slowly reduces the side effects for participants with relapsed or refractory neuroblastoma. The name of the study drugs involved in this study are: * Naxitamab (A type of monoclonal antibody) * Irinotecan (A standard of care chemotherapy) * Temozolomide (A standard of care chemotherapy) * Sargramostim (A standard of care, granulocyte-macrophage colony stimulating factor)

This is a Phase 1 study with Phase 2 expansion cohort. Phase 1 will assess the safety and tolerability of universal donor TGFβi NK Cell in combination with irinotecan, temozolomide, and dinituximab. The phase 2 of the study will estimate the response to treatment.
