Irinotecan Hydrochloride, Temozolomide, and Dinutuximab With or Without Eflornithine in Treating Patients With Relapsed or Refractory Neuroblastoma

Not Recruiting

Trial ID: NCT03794349


This phase II trial studies how well irinotecan hydrochloride, temozolomide, and dinutuximab work with or without eflornithine in treating patients with neuroblastoma that has come back (relapsed) or that isn't responding to treatment (refractory). Drugs used in chemotherapy, such as irinotecan hydrochloride and temozolomide, 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. Immunotherapy with monoclonal antibodies, such as dinutuximab, may induce changes in the body's immune system and may interfere with the ability of tumor cells to grow and spread. Eflornithine blocks the production of chemicals called polyamines that are important in the growth of cancer cells. Giving eflornithine with irinotecan hydrochloride, temozolomide, and dinutuximab, may work better in treating patients with relapsed or refractory neuroblastoma.

Inclusion Criteria:

   - Patients must have had histologic verification of neuroblastoma or
   ganglioneuroblastoma or demonstration of neuroblastoma cells in the bone marrow with
   elevated urinary catecholamines (i.e. > 2 x upper limit of normal [ULN]), at the time
   of initial diagnosis.

   - For the purposes of this study, aggressive multidrug chemotherapy is defined as
   chemotherapy including 2 or more agents that must include an alkylating agent and a
   platinum-containing compound as intended to treat high-risk disease. The doses of
   chemotherapy must be comparable to those used in frontline high-risk neuroblastoma
   therapies (examples include A3973, ANBL0532, ANBL09P1, ANBL12P1, and ANBL1531).
   Patients must have ONE of the following:

      - First episode of recurrent high-risk disease following completion of aggressive
      multi-drug frontline high-risk therapy.

      - First episode of progressive high-risk disease during aggressive multi-drug
      frontline therapy.

      - Primary resistant/refractory disease (less than partial response by International
      Neuroblastoma Response Criteria [INRC]) detected at the conclusion of at least 4
      cycles of aggressive multidrug induction chemotherapy on or according to a
      high-risk neuroblastoma protocol (examples include A3973, ANBL0532, ANBL09P1,
      ANBL12P1, ANBL1531, etc.).

   - Patients must have at least ONE of the following at the time of enrollment:

      - Measurable tumor on magnetic resonance imaging (MRI) or computed tomography (CT)
      scan. Measurable is defined as >= 10 mm in at least one dimension on
      spiral/helical CT that is metaiodobenzylguanidine (MIBG) avid or demonstrates
      increased fludeoxyglucose F-18 (FDG) uptake on positron emission tomography (PET)

      - MIBG-avid lesion detected on MIBG scan with positive uptake at a minimum of one
      site. This site must represent disease recurrence after completion of therapy,
      progressive disease on therapy, or refractory disease during induction.

      - Patients with resistant/refractory soft tissue disease that is not MIBG avid or
      does not demonstrate increased FDG uptake on PET scan must undergo biopsy to
      document the presence of viable neuroblastoma. Biopsy is not required for
      patients who have a new site of soft tissue disease (radiographic evidence of
      disease progression) regardless of whether progression occurs while receiving
      therapy or after completion of therapy.

      - Patients with bone marrow disease only will be eligible if they have more than 5%
      disease involvement (documented neuroblastoma cells) in at least one sample from
      bilateral bone marrow biopsies.

      - Note: Patients with elevated catecholamines (i.e. > 2 x ULN) only are NOT
      eligible for this study.

   - Patients must have a performance status corresponding to Eastern Cooperative Oncology
   Group (ECOG) scores of 0, 1 or 2. Use Karnofsky for patients > 16 years of age and
   Lansky for patients =< 16 years of age.

   - Primary refractory/resistant patients must have received at least 4 cycles of
   frontline high-risk chemotherapy. Frontline therapy may also have included surgery,
   chemotherapy, autologous stem cell transplantation (SCT) +/- MIBG, immunotherapy,
   radiotherapy, and retinoids but must NOT have received second line therapy for
   resistant/refractory, relapsed, or progressive disease. Patients who received
   intensified therapy for poor induction response or refractory disease (e.g. MIBG) will
   be considered to have received second line therapy and will not be eligible.

   - At least 14 days must have elapsed since completion of myelosuppressive therapy.

   toxicity related to prior antibody therapy must be recovered to grade =< 1.

   - No interim time prior to study entry is required following prior radiation therapy
   (RT) for non-target lesions. However, patients must not have received radiation for a
   minimum of 4 weeks prior to study entry at the site of any lesion that will be
   identified as a target lesion to measure tumor response. Lesions that have been
   previously radiated cannot be used as target lesions unless there is radiographic
   evidence of progression at the site following radiation or a biopsy done following
   radiation shows viable neuroblastoma. Palliative radiation while on study is not

   - Patients are eligible >= 6 weeks after autologous stem cell transplants or stem cell

   retinoids for biologic therapy are eligible unless they have had progressive disease
   while receiving prior anti-GD2 therapy or progressed/relapsed within 3 months of
   receiving anti-GD2 therapy. However, eligible patients may NOT have received anti-GD2
   monoclonal antibodies in combination with chemotherapy.

   - Subjects who have received autologous marrow infusions or autologous stem cell
   infusions that were purged using monoclonal antibody linked to beads are eligible.

   contraception while enrolled on this study. Based on the established teratogenic
   potential of alkylating agents, pregnant women will be excluded from this study.
   Because of potential risks to breastfed infants due to drug metabolites that could be
   excreted in breast milk, female patients who are lactating must agree to stop
   breastfeeding or will otherwise be excluded from this study. Females of childbearing
   potential must have a negative pregnancy test to be eligible for this study.

   - Patients with only elevated catecholamines (i.e. > 2 x ULN) are NOT eligible for this

   hydrocortisone (or an equivalent dose of an alternative corticosteroid) as
   premedication for blood product administration in order to avoid allergic transfusion
   reactions. The use of conventional doses of inhaled steroids for the treatment of
