Description:
This is a prospective randomized clinical trial, to determine whether dose-intensive tandem
Consolidation, in a randomized comparison with single cycle Consolidation, provides an
event-free survival (EFS) and overall survival (OS). The study population will be high-risk
patients (non-Wnt and non-Shh sub-groups) with medulloblastoma, and for all patients with
central nervous system (CNS) embryonal tumors completing "Head Start 4" Induction. This study
will further determine whether the additional labor intensity (duration of hospitalizations
and short-term and long-term morbidities) associated with the tandem treatment is justified
by the improvement in outcome. It is expected that the tandem (3 cycles) Consolidation
regimen will produce a superior outcome compared to the single cycle Consolidation, given the
substantially higher dose intensity of the tandem regimen, without significant addition of
either short-term or long-term morbidities.

Purpose
This is a prospective randomized clinical trial, to determine whether dose-intensive tandem
Consolidation, in a randomized comparison with single cycle Consolidation, provides an
event-free survival (EFS) and overall survival (OS). The study population will be high-risk
patients (non-Wnt and non-Shh sub-groups) with medulloblastoma, and for all patients with
central nervous system (CNS) embryonal tumors completing "Head Start 4" Induction. This study
will further determine whether the additional labor intensity (duration of hospitalizations
and short-term and long-term morbidities) associated with the tandem treatment is justified
by the improvement in outcome. It is expected that the tandem (3 cycles) Consolidation
regimen will produce a superior outcome compared to the single cycle Consolidation, given the
substantially higher dose intensity of the tandem regimen, without significant addition of
either short-term or long-term morbidities.
Detailed Description
Due to the inferior response and event-free survival data of Regimens D and D2 on "Head Start
III" for all children with supratentorial embryonal tumors, in comparison with the published
data from "Head Start II" with Regimen A2 for metastatic patients, all such patients will
receive the "Head Start II" Induction Regimen A2, on "Head Start 4", for either three or five
cycles, depending upon whether or not they achieve complete remission by the end of Induction
cycle #3. They will then undergo randomization to either single cycle or three tandem cycles
of Consolidation marrow-ablative chemotherapy with AuHPCR.
Because of the unsatisfactory event-free survival for young children with
non-desmoplastic/extensive nodular medulloblastoma (predominantly non-Shh and non-Wnt
medulloblastoma subgroups) on Regimens D and D2 of "Head Start III", all these patients will
receive the "Head Start II" Induction Regimen A2 on ""Head Start 4"", for either three or
five cycles, depending upon whether or not they achieve complete remission by the end of
Induction cycle #3. They will then undergo randomization to either single cycle or three
tandem cycles of Consolidation marrow-ablative chemotherapy with AuHPCR.
Because of the excellent event-free and overall survival for young children with good risk
medullo-blastoma (Shh or Wnt subgroups) treated with up-front "Head Start" chemotherapy
strategies, such patients will undergo risk-tailored reduction of duration of Induction
therapy from five cycles to three cycles of the "Head Start II" Induction Regimen A2 on "Head
Start 4" for patients achieving a complete response to 3 cycles, followed, provided they are
also without evidence of residual tumor following recovery from Induction cycle #3. They will
NOT then undergo randomization, but will follow with a single cycle of Consolidation
marrow-ablative chemotherapy as in "Head Start" studies.
Trial Arms
Name | Type | Description | Interventions |
---|
Induction | Experimental | The 5 chemotherapy drugs used in the Induction part of treatment are vincristine, cisplatin, cyclophosphamide, etoposide and high-dose methotrexate.
Three medications are also given to help reduce the side effects of the chemotherapy drugs. Filgrastim will be given through a vein or through a tiny needle into the tissue just under the skin to help blood counts recover after the chemotherapy. Mesna will be given through a vein with cyclophosphamide to help prevent bleeding in the bladder. Leucovorin will be given through a vein after the methotrexate to protect the body from the side effects of the methotrexate. | |
Single Cycle Intensive Chemotherapy | Experimental | The three drugs to be used in this research study are thiotepa, etoposide and carboplatin. These drugs will be given over 6 days to help kill the cancer cells. After 72 hours from getting these drugs, previously collected and frozen blood cells will be thawed and returned through the venous catheter.
Carboplatin is given by vein over 4 hours. Thiotepa is given by vein over 3 hours. Etoposide is given by vein over 3 hours. The schedule for these drugs is as follows:
Day -8: Carboplatin Day -7: Carboplatin Day -6: Carboplatin Day -5: Thiotepa, Etoposide Day -4: Thiotepa, Etoposide Day -3: Thiotepa, Etoposide Day -2: Rest Day -1: Rest Day 0: Re-infusion of blood cells | - Single Cycle Intensive Chemotherapy
|
Tandem 3 Cycle Intensive Chemotherapy | Experimental | The 2 drugs to be used in this treatment are thiotepa and carboplatin. These drugs will be given over 2 days to help kill the cancer cells. After 72 hours from getting these drugs, previously collected and frozen blood cells will be thawed and returned through the venous catheter.
Day -4: Thiotepa, Carboplatin Day -3: Thiotepa, Carboplatin Day -2: Rest Day -1: Rest Day 0: Re-infusion of blood cells.
Following recovery from the first cycle of this chemotherapy, about 28 days following the Day 0 reinfusion of blood cells, the same cycle will be repeated again. A total of 3 cycles of this therapy will be administered, over the course of 12 weeks. | - Tandem 3 Cycle Intensive Chemotherapy
