Study Description

Brief Summary:

This phase I trial is to find out the best dose, possible benefits and/or side effects of magrolimab in combination with dinutuximab in treating patients with neuroblastoma that has come back (relapsed) or does not respond to treatment (refractory) or relapsed osteosarcoma. Magrolimab and dinutuximab are monoclonal antibodies that may interfere with the ability of tumor cells to grow and spread. The combination of magrolimab and dinutuximab may shrink or stabilize relapsed or refractory neuroblastoma or relapsed osteosarcoma. In addition, this trial may help researchers find out if it is safe to give magrolimab and dinutuximab after surgery to remove tumors from the lungs.

Detailed Description:

PRIMARY OBJECTIVES:

I. Determine the safety and tolerability of Hu5F9-G4 (magrolimab) in combination with dinutuximab in children and young adults with relapsed/refractory (R/R) neuroblastoma (NBL) or relapsed osteosarcoma.

II. Determine the recommended phase 2 dose (RP2D) of Hu5F9-G4 (magrolimab) given in combination with dinutuximab in children and young adults.

III. Determine the safety and feasibility of administering Hu5F9-G4 (magrolimab) in combination with dinutuximab to patients that undergo pulmonary resection of metastatic osteosarcoma within three weeks of surgery.

SECONDARY OBJECTIVES:

I. Determine the pharmacokinetics (PK) of Hu5F9-G4 (magrolimab) in children and young adults.

II. Evaluate the event free survival (EFS) in two cohorts of patients who are treated at the recommended phase 2 dose (RP2D) (measurable relapsed osteosarcoma and patients with pulmonary relapse undergoing resection) and compare to historical controls.

III. Observe and record anti-tumor activity. IV. Evaluate the overall response rate (ORR) of patients in the NBL cohorts (measurable R/R NBL and evaluable R/R NBL) and osteosarcoma patients (measurable relapsed osteosarcoma) in the expansion cohorts treated at the RP2D.

EXPLORATORY OBJECTIVES:

I. To explore biomarkers of response and resistance including genomic (CD47 expression, Fc receptor [FcR] polymorphisms, SIRPa polymorphisms, and KiR phenotype) and immunologic (dinutuximab HACA, magrolimab ADA, peripheral and bone marrow immune subsets, and circulating cytokines).

II. To explore biomarkers of response in the tumor microenvironment through multiplexed ion beam imaging (MIBI) on resected tissue or archival tissues including comparison of pre- and post- treatment tumor tissues from patients undergoing staged resection of pulmonary osteosarcoma.

OUTLINE: This is a dose de-escalation study of magrolimab with fixed-dose dinutuximab followed by a dose-expansion study. Patients are assigned to 1 of 2 arms.

ARM A: Patients receive magrolimab intravenously (IV) over 2 hours on days 1, 8, and 15 of cycles 1-2 and days 1 and 15 of subsequent cycles, and dinutuximab IV over 10 hours on days 2-5. Treatment repeats every 21 days for up to 12 cycles in the absence of disease progression or unacceptable toxicity.

ARM B: Patients receive magrolimab IV over 2 hours on days 1, 8, and 15 of cycles 1-2 and days 1 and 15 of subsequent cycles, and dinutuximab IV over 10 hours on days 2-5. Treatment repeats every 21 days for up to 12 cycles in the absence of disease progression or unacceptable toxicity. Patients with pulmonary osteosarcoma may undergo surgical resection of tumor after cycle 1. After surgery, these patients continue receiving magrolimab and dinutuximab every 21 days for up to 5 cycles in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days, at 2, 4, 6, 9, and 12 months, and then yearly for 4 years.

Study Description

This is a multicenter pilot study of SurVaxM (SVN53-67/M57-KLH) for children and young adults with progressive or relapsed medulloblastoma, high grade glioma, ependymoma and newly diagnosed diffuse intrinsic pontine glioma.

Survivin (BIRC5) is an inhibitor of apoptosis (IAP) protein that is highly expressed in many cancers. Survivin's high level of expression in certain pediatric malignancies makes it an attractive molecular target for new therapies, including active specific vaccination-based immunotherapy.

The design of the SurVaxM vaccine employs several strategies to create an effective antitumor immunogen, including: 1) incorporation of multiple MHC class I epitopes, 2) peptide modification to enhance binding to certain MHC class I molecules, 3) cytokine helper support, and 4) antibody-mediated tumor cell killing. All of these effects would not be expected with the unmodified class-I restricted short survivin peptides employed in previously studied glioma vaccines.

There are no prior clinical trials of SurVaxM in pediatric patients; however, SurVaxM has been studied in several adult trials, including a phase I study conducted at Roswell Park Comprehensive Cancer Center. Following the single-institution phase I trial, a multicenter phase IIa trial (NCT024455557) was conducted in 63 patients with newly diagnosed glioblastoma. All patients in this study underwent surgical resection of their tumors. Patients then underwent chemoradiation with temozolomide according to the Stupp protocol. This was followed by a one-month hiatus from chemotherapy, during which priming doses of SurVaxM were initiated. The priming phase of vaccination was then followed by initiation of standard adjuvant chemotherapy with temozolomide and maintenance doses of SurVaxM as an add-on to standard chemotherapy. There have been no regimen-limiting toxicities (RLT) or grade ≥ 3 SAE attributable to SurVaxM, with most toxicities being related to temozolomide. The most common AE was grade 1-2 injection site reaction with 2 patients experiencing Montanide-related granulomatous panniculitis with local skin ulceration at vaccine injection sites, both of which resolved. Humoral and survivin-specific CD8+ T cell responses were observed in almost all patients. Twelve-month overall survival (OS12) was 86% from first immunization and 93.4% from diagnosis. OS12 for meMGMT was 93.1% and unMGMT was 78% from first immunization. Median time to tumor progression (mPFS) was 13.9 months from diagnosis. Although not a randomized trial, these results are superior to overall survival reported in various studies in which patients received standard of care treatment for this disease. A randomized phase IIb clinical trial of standard therapy plus SurVaxM is currently being developed with intent for drug registration, if successful.

The primary objective of this trial is to assess the toxicity profile of SurVaxM in emulsion with Montanide plus sargramostim in children with relapsed or progressive medulloblastoma and high-grade glioma, ependymoma and non-recurrent diffuse intrinsic pontine glioma post-radiation therapy. Patients will be enrolled into three separate strata based on age and diagnosis. Enrollment will be staged to allow for safety evaluations between strata.

Each patient will receive 500 micrograms SurVaxM as a 1:1 mixture with Montanide ISA 51 in a water-in-oil emulsion. The SurVaxM-Montanide emulsion injection will be followed immediately by sargramostim (or biosimilar) given via a second separate subcutaneous injection in close proximity to the vaccine injection site. Patients will receive four injections administered over a 6-week period, followed by 14 days of follow-up, called the Priming Phase (8 weeks total). Beginning 8 weeks after the fourth priming dose, a maintenance dose of SurVaxM with Montanide ISA 51 may be given every 8 weeks (± 2 weeks) for two years or until an off-treatment criterion is met.

Inclusion Criteria
  • DIAGNOSIS: Patients with a histologically confirmed diagnosis of a primary CNS tumor that is progressive or recurrent defined as progression in any known residual tumor, or the appearance of one or more new lesions, or new cerebrospinal fluid (CSF) positivity for malignant cells, after having failed standard therapy. At the time of diagnosis or recurrence, all tumors must have histologic verification of one of the following:
    • Medulloblastoma

Patients with diffuse intrinsic pontine gliomas (DIPGs), defined as tumors with a pontine epicenter and diffuse involvement of 2/3 or more of the pons, are eligible without histologic confirmation. Patients with brainstem tumors that do not meet these criteria or not considered to be typical intrinsic pontine gliomas will only be eligible if the tumors have been biopsied and are proven to be a glioblastoma multiforme (GBM), or astrocytoma (Grade II or Grade III). DIPG patients with disseminated disease are not eligible, and MRI of spine must be performed if disseminated disease is suspected by the treating physician.

Study Description

Brief Summary:

The study evaluates CLR 131 in children, adolescents, and young adults with relapsed or refractory High Grade Glioma (HGG) for which there are no standard treatment options with curative potential.

Part A for Solid Tumors, Lymphoma, and Malignant  Brain Tumors is now closed. This study is exclusively enrolling on Part B for HGG

 

Detailed Description:

Even with standard, highly toxic multimodality therapies and salvage regimen, most pediatric patients with primary metastatic or relapsed solid tumors are confronted with a poor prognosis. For these patients there is currently no accepted successful treatment regimen. There is a need for new drugs, including targeted radiopharmaceuticals, preferably with cancer-specific uptake and broad applicability for these rare pediatric malignancies.

CLR 131 is a radioiodinated therapeutic that exploits the selective uptake and retention of phospholipid ethers (PLEs) by malignant cells. Cellectar Biosciences' novel cancer-targeted small-molecule compound (CLR1404) is radiolabeled with the isotope iodine-131 (I-131). CLR 131 has demonstrated tumor selective uptake across numerous adult and pediatric cancer cell types. Therapeutic efficacy has been demonstrated in various pediatric and adult-type cancer xenograft models, confirming the ability of CLR 131 to target tumors.

Based on the critical unmet medical need for effective agents with novel mechanisms of action in relapsed pediatric cancers and initial preclinical and clinical experience with radioiodinated CLR1404, Cellectar Biosciences has chosen to assess CLR 131 in a phase 1 pediatric trial.

Inclusion Criteria
  • Previously confirmed (histologically or cytologically) HGG that is clinically or radiographically suspected to be relapsed, refractory, or recurrent. Patients with DIPG are exempt from histologic verification if they have typical MRI findings of DIPG (i.e., hypo- or isointense on T1-weighted imaging, hyperintense on FLAIR or T2-weighted imaging, epicenter in the pons, greater than 50% of pons involved) and the risk of tumor biopsy is prohibitive
  • Patient is ≥ 10 years and ≤ 25 years of age at time of consent/assent
  • Patients ≥ age 16 years must have a Karnofsky performance status of ≥ 60. Patients < age 16 years must have a Lansky performance status of ≥ 60
  • Patients must meet the following lab criteria:

Study Description

Brief Summary:

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.

Detailed Description:

ONITT (ONIvyde, Talazoparib, Temozolomide) is a phase I/II study which will evaluate two treatment regimens; nanoliposomal irinotecan (nal-IRN, Onivyde) plus talazoparib (TAL) and Onivyde (ONI) plus temozolomide (TMZ) for the treatment of recurrent or refractory (RR) Ewing sarcoma. A dose finding phase I study will be open to patients with recurrent or refractory solid tumors. Patients will be assigned to receive either ONI plus TAL (Arm A) or ONI plus TMZ (Arm B). Once the recommended phase II doses (RP2D) of Arm A and Arm B are determined, expansion cohorts (A1, B1) will open at the RP2Ds for enrollment of non-Ewing sarcoma solid tumor patients. There will be an additional Arm A expansion cohort (A2) for patients with homologous recombination repair defects. Concurrently, the phase II study will open to patients with RR Ewing sarcoma. In the phase II study, patients with RR Ewing sarcoma will be randomized to receive either ONI plus TAL or ONI plus TMZ. The primary endpoint will be progression-free survival (PFS). PFS of both treatment arms in the phase II study will be compared to one another by using a two-arm non-inferiority design when superiority is expected.

Phase I Primary Objective To determine the recommended phase 2 doses (RP2Ds) of Onivyde combined with talazoparib (Arm A) and Onivyde combined with temozolomide (Arm B) administered to children, adolescents and young adults with refractory or recurrent solid malignancies.

Phase I Secondary Objectives

  • To characterize the safety profile of the drug regimens, Onivyde plus talazoparib (Arm A) and Onivyde plus temozolomide (Arm B).
  • To characterize the plasma pharmacokinetics (PK) of Onivyde and talazoparib in children, adolescents and young adults with refractory or recurrent solid malignancies.
  • To estimate the antitumor activity of Onivyde plus talazoparib and Onivyde plus temozolomide.

Phase I Exploratory Objectives

  • To describe the relationship between UGT1A1 genotype status with toxicity and response.
  • To describe the molecular profile of germline and tumors, including evaluation of mutations in homologous recombination genes and their possible association to therapy response in patients with recurrent or refractory solid tumors.
  • To measure ctDNA at different time points and evaluate its relationship with response to therapy.
  • To describe the safety profile of the combination Onivyde plus talazoparib and Onivyde plus temozolomide at the determined RP2D in children, adolescents and young adults treated in the expansion cohorts.
  • To describe the palatability and ease of administration of talazoparib liquid suspension in children who are unable to swallow the capsules.

Phase II Primary Objectives

• To compare the progression-free survival (PFS) of Onivyde plus talazoparib and Onivyde plus temozolomide in patients with refractory or recurrent Ewing sarcoma.

Phase II Secondary Objectives

  • To describe the toxicity of the treatment regimens.
  • To describe the objective response rate (ORR), disease control rate (DCR) after cycle 4, duration of response (DoR), event free survival (EFS) and overall survival (OS) for patients receiving Onivyde plus talazoparib and Onivyde plus temozolomide.
  • To characterize the plasma pharmacokinetics of Onivyde and talazoparib in children, adolescents and young adults with refractory or recurrent Ewing sarcoma.

Phase II Exploratory Objectives

  • To describe the relationship between UGT1A1 genotype status with toxicity and response.
  • To describe the molecular profile of germline and tumors, including evaluation of mutations in homologous recombination genes and their possible association to chemotherapy response in patients with recurrent or refractory Ewing sarcoma.
  • To describe ctDNA at different time points and the relationship with response to therapy.
  • To describe the palatability and ease of administration of talazoparib liquid suspension in children who are unable to swallow the capsules.

Phase I The phase I portion of the study will include 2 separate treatment arms, Arms A and B. Arm A will evaluate Onivyde plus talazoparib (ONI + TAL). Arm B will evaluate Onivyde plus temozolomide (ONI + TMZ). Both phase I studies will be open to patients with recurrent or refractory solid tumors who meet eligibility criteria. In Arm A, patients will receive intravenous Onivyde on Days 1 and 8. They will receive oral talazoparib twice on Day 1 and then daily on Days 2-6. In Arm B, patients will receive intravenous Onivyde on Days 1 and 8. They will receive oral temozolomide daily on Days 1-5. Pharmacokinetic testing will take place during Cycle 1. Therapy may continue for up to 24 months. Tumor assessments will be performed at baseline and repeated after cycles 2, 4, 6 and then every 4 cycles thereafter to assess disease status. If at any designated disease evaluation time point a patient develops a response that is better than the prior response (i.e. SD at Cycle 2 evaluation, then PR at Cycle 4 evaluation), an interim disease evaluation is recommended after 28 days to confirm response. Therapy will be discontinued if there is evidence of disease progression or drug-related dose limiting toxicities requiring removal from treatment. Safety and tolerability will be monitored continuously throughout study participation.

Phase II Following the completion of the phase I dose finding studies, patients with recurrent or refractory Ewing sarcoma that meet eligibility criteria will be eligible for randomization into the phase II study. Arm A will evaluate Onivyde plus talazoparib (ONI + TAL). Arm B will evaluate Onivyde plus temozolomide (ONI + TMZ). In Arm A, patients will receive intravenous Onivyde on Days 1 and 8. They will receive oral talazoparib twice on Day 1 and then daily on Days 2-6. In Arm B, patients will receive intravenous Onivyde on Days 1 and 8. They will receive oral temozolomide daily on Days 1-5. Pharmacokinetic testing will take place during Cycle 1. Therapy may continue for up to 24 months. Tumor assessments will be performed at baseline and repeated after Cycles 2, 4, 6 and then every 4 cycles thereafter to assess disease status. If at any designated disease evaluation time point a patient develops a response that is better than the prior response (i.e. SD at Cycle 2 evaluation, then PR at Cycle 4 evaluation), an interim disease evaluation is recommended after 28 days to confirm response. Therapy will be discontinued if there is evidence of disease progression and/or any other condition(s) occur that do not allow treatment continuation or similar toxicities requiring removal from the trial. Safety and tolerability will be monitored continuously throughout study participation.

Sample size: In the dose escalation phase I study, approximately 18 patients per arm will be enrolled for a total of 36 patients. The dose expansion phase I study will include 3 treatment cohorts. Arm A will have 2 dose expansion cohorts including 1) a non-ES solid tumor cohort (A1) and 2) a DNA repair defects/mutations cohort (A2). Arm B will have 1 dose expansion cohort including non-ES solid tumors (B1). Approximately 12 patients will enroll per expansion treatment cohort for a total of 36 patients. In the phase II study, 44 patients will be enrolled on each arm for a total of 88 patients.

Study Description

This phase II trial studies how well combination chemotherapy works in treating patients with newly diagnosed stage II-IV diffuse anaplastic Wilms tumors (DAWT) or favorable histology Wilms tumors (FHWT) that have come back (relapsed). Drugs used in chemotherapy regimens such as UH-3 (vincristine, doxorubicin, cyclophosphamide, carboplatin, etoposide, and irinotecan) and ICE/Cyclo/Topo (ifosfamide, carboplatin, etoposide, cyclophosphamide, and topotecan) work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. This trial may help doctors find out what effects, good and/or bad, regimen UH-3 has on patients with newly diagnosed DAWT and standard risk relapsed FHWT (those treated with only 2 drugs for the initial WT) and regimen ICE/Cyclo/Topo has on patients with high and very high risk relapsed FHWT (those treated with 3 or more drugs for the initial WT).

 

PRIMARY OBJECTIVES:

I. To evaluate whether the addition of vincristine/irinotecan to cyclophosphamide/ carboplatin/etoposide alternating with vincristine/doxorubicin/cyclophosphamide improves the event-free survival (EFS) of patients with newly diagnosed stage 4 diffuse anaplastic Wilms tumor (DAWT) as compared to historical controls.

II. To evaluate whether the addition of vincristine/irinotecan to cyclophosphamide/carboplatin/etoposide alternating with vincristine/doxorubicin/cyclophosphamide improves the EFS of patients with standard-risk relapsed favorable histology Wilms tumor (SRrFHWT) as compared to historical controls.

SECONDARY OBJECTIVES:

I. To evaluate whether the addition of vincristine/irinotecan to cyclophosphamide/carboplatin/etoposide alternating with vincristine/doxorubicin/cyclophosphamide improves the overall survival (OS) of patients with newly diagnosed stage 4 DAWT as compared to historical controls.

II. To evaluate whether the addition of vincristine/irinotecan to cyclophosphamide/carboplatin/etoposide alternating with vincristine/doxorubicin/cyclophosphamide improves the OS of patients with SRrFHWT as compared to historical controls.

III. To evaluate whether the addition of vincristine/irinotecan to cyclophosphamide/carboplatin/etoposide alternating with vincristine/doxorubicin/cyclophosphamide improves the EFS and OS of patients with newly diagnosed stage 2 and 3 DAWT as compared to historical controls.

IV. To establish EFS and OS for high-risk (HRrFHWT) and very high risk (VHRrFHWT) relapsed favorable histology Wilms tumor treated with ifosfamide/carboplatin/etoposide alternating with cyclophosphamide/ topotecan.

EXPLORATORY OBJECTIVES:

I. To describe renal toxicity of ifosfamide/carboplatin/etoposide in HRrFHWT and VHRrFHWT patients using conventional and novel biomarkers of renal toxicity (urine NGAL, cystatin C and Kim1) in the context of the chemotherapy regimens used on this study.

II. To collect and bank serial blood and urine samples in patients with newly diagnosed DAWT or relapsed FHWT and tumor tissue in patients with relapsed FHWT, for future analysis.

III. To assess the impact of p53 gene and protein expression on outcome for patients with newly diagnosed DAWT.

IV. To determine EFS/OS in the subsets of patients with newly diagnosed DAWT or relapsed FWHT who undergo gross total resection at all disease sites at diagnosis or after neoadjuvant chemotherapy.

V. To describe the rate of regional lymph node sampling at the time of nephrectomy with the use of a pre-operative surgical checklist for patients with newly diagnosed DAWT.

VI. To determine the feasibility of intensity modulated radiation therapy (IMRT) with central quality assurance (QA) monitoring to reduce radiation induced toxicity to the heart, thyroid, breast and solitary kidney for children with lung and liver metastases (part of an overarching aim in this study and across frontline favorable histology Wilms tumor studies).

Study Description

This phase II trial studies how well reduced doses of radiation therapy to the brain and spine (craniospinal) and chemotherapy work in treating patients with newly diagnosed type of brain tumor called WNT)/Wingless (WNT)-driven medulloblastoma. Recent studies using chemotherapy and radiation therapy have been shown to be effective in treating patients with WNT-driven medulloblastoma. However, there is a concern about the late side effects of treatment, such as learning difficulties, lower amounts of hormones, or other problems in performing daily activities. Radiotherapy uses high-energy radiation from x-rays to kill cancer cells and shrink tumors. Drugs used in chemotherapy, such as cisplatin, vincristine sulfate, cyclophosphamide and lomustine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving reduced craniospinal radiation therapy and chemotherapy may kill tumor cells and may also reduce the late side effects of treatment.
