Imetelstat Sodium in Treating Younger Patients With Relapsed or Refractory Solid Tumors

NCT ID: NCT02011126

Last Updated: 2018-08-07

Basic Information

• Recruitment Status: WITHDRAWN
• Clinical Phase: PHASE2
• Study Classification: INTERVENTIONAL
• Study Start Date: 2014-06-30

Brief Summary

This phase II trial studies the side effects and how well imetelstat sodium works in treating younger patients with relapsed or refractory solid tumors. Imetelstat sodium may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Detailed Description

PRIMARY OBJECTIVES:

I. To determine the objective response rate, defined as partial response or better, of imetelstat (imetelstat sodium) in children with relapsed or refractory solid tumors.

II. To further define and describe the toxicities associated with imetelstat in children with recurrent/refractory solid tumors.

SECONDARY OBJECTIVES:

I. To determine the time to progression following treatment with imetelstat in children with relapsed or refractory solid tumors.

TERTIARY OBJECTIVES:

I. To measure tumor telomere length in archival samples, and to correlate telomere length to the clinical outcome of the study.

OUTLINE:

Patients receive imetelstat sodium intravenously (IV) over 2 hours on days 1 and 8. Treatment repeats every 21 days for up to 36 courses in the absence of disease progression or unacceptable toxicity.

Conditions

Hepatoblastoma; Previously Treated Childhood Rhabdomyosarcoma; Recurrent Childhood Liver Cancer; Recurrent Childhood Rhabdomyosarcoma; Recurrent Ewing Sarcoma/Peripheral Primitive Neuroectodermal Tumor; Recurrent Neuroblastoma; Recurrent Osteosarcoma; Rhabdomyosarcoma

Study Design

• Allocation Method: NA
• Intervention Model: SINGLE_GROUP

Eligibility Criteria

Inclusion Criteria

• Patients with any of the following tumors who have relapsed or refractory disease are eligible:

• Osteosarcoma
• Ewing?s sarcoma / peripheral primitive neuroectodermal tumor (PNET)
• Rhabdomyosarcoma
• Neuroblastoma (measurable or evaluable disease)
• Hepatoblastoma
• Patients must have had histologic verification of malignancy at original diagnosis or relapse
• Patients must have radiographically measurable disease (with the exception of neuroblastoma)

• Measurable disease is defined as the presence of at least one lesion on magnetic resonance imaging (MRI) or computed tomography (CT) scan that can be accurately measured with the longest diameter a minimum of 10 mm in at least one dimension (CT scan slice thickness no greater than 5 mm)
• Note: the following do not qualify as measurable disease:

• Malignant fluid collections (e.g., ascites, pleural effusions)
• Bone marrow infiltration
• Lesions only detected by nuclear medicine studies (e.g., bone, gallium or positron emission tomography [PET] scans) except as defined below for neuroblastoma
• Elevated tumor markers in plasma or cerebrospinal fluid (CSF)
• Previously radiated lesions that have not demonstrated clear progression post radiation
• Leptomeningeal lesions that do not meet the measurements noted above
• Patients with neuroblastoma who do not have measurable disease but have evaluable disease on 131I-metaiodobenzylguanidine (MIBG) scans are eligible
• Patients must have a Lansky or Karnofsky performance status score of >= 50, corresponding to Eastern Cooperative Oncology Group (ECOG) categories 0, 1 or 2; use Karnofsky for patients > 16 years of age and Lansky for patients =< 16 years of age; patients who are unable to walk because of paralysis, but who are up in a wheelchair, will be considered ambulatory for the purpose of assessing the performance score
• Patients must have fully recovered from the acute toxic effects of all prior chemotherapy, immunotherapy, or radiotherapy prior to entering this study
• Myelosuppressive chemotherapy: patients with solid tumors must not have received myelosuppressive chemotherapy within 3 weeks of enrollment onto this study (6 weeks if prior nitrosourea)
• Hematopoietic growth factors: at least 7 days must have elapsed since the completion of therapy with a growth factor; at least 14 days must have elapsed after receiving pegfilgrastim
• Biologic (anti-neoplastic agent): at least 7 days must have elapsed since completion of therapy with a biologic agent; for agents that have known adverse events occurring beyond 7 days after administration, this period prior to enrollment must be extended beyond the time during which adverse events are known to occur
• Monoclonal antibodies: at least 3 half-lives must have elapsed since prior therapy that included a monoclonal antibody
• Radiotherapy: >= 2 weeks must have elapsed since local palliative radiation therapy (XRT) (small port); >= 6 weeks must have elapsed since treatment with therapeutic doses of MIBG; >= 3 months must have elapsed if prior craniospinal XRT was received, if >= 50% of the pelvis was irradiated, or if total body irradiation (TBI) was received; >= 6 weeks must have elapsed if other substantial bone marrow irradiation was given
• Stem cell transplant or rescue without TBI: no evidence of active graft versus (vs.) host disease and >= 2 months must have elapsed since transplant
• For patients with solid tumors without bone marrow involvement:

• Peripheral absolute neutrophil count (ANC) >= 1000/uL
• For patients with solid tumors without bone marrow involvement:

• Platelet count >= 100,000/uL (transfusion independent, defined as not receiving platelet transfusions within a 7 day period prior to enrollment)
• For patients with solid tumors without bone marrow involvement:

• Hemoglobin >= 8.0 g/dL (may receive red blood cell [RBC] transfusions).
• For patients with solid tumors and known bone marrow metastatic disease:

• Peripheral absolute neutrophil count (ANC) >= 750/uL
• For patients with solid tumors and known bone marrow metastatic disease:

• Platelet count >= 50,000/uL
• For patients with solid tumors and known bone marrow metastatic disease:

• Hemoglobin >= 8.0 g/dL

• Transfusions are permitted to meet both the platelet and hemoglobin criteria; patients must not be known to be refractory to red blood cell or platelet transfusions
