Myeloablative Consolidation Therapy and Tandem Autologous Stem Cell Rescue in Patients With High-Risk Neuroblastoma
What this study is about
This is a phase II single center study to administer two courses of myeloablative consolidation chemotherapy each followed by an autologous peripheral blood stem cell (PBSC) rescue in patients with high-risk neuroblastoma who have completed induction chemotherapy (independent of this study).
View original scientific description
This is a phase II single center study to administer two courses of myeloablative consolidation chemotherapy each followed by an autologous peripheral blood stem cell (PBSC) rescue in patients with high-risk neuroblastoma who have completed induction chemotherapy (independent of this study). Ideally, patients should begin consolidation chemotherapy no later than 8 weeks after the start of Induction Cycle #5; however it is strongly recommended to begin consolidation within 4-6 weeks after the start of Induction Cycle #5.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Less than 30 years of age at diagnosis of neuroblastoma
- End of Induction disease evaluation demonstrating CR, PR, MR or SD
- Hematopoietic Recovery from last induction course of chemotherapy
- No uncontrolled infection
- Minimum frozen PBSCs of 2 x 10\^6 CD34 cells/kg for each transplant are mandatory and a PBSC of 2 x 10\^6 CD34 cells/kg for back-up are strongly recommended (thus, PBSC of no less than 6 x 10\^6 CD34 cells/kg is encouraged). These must all be collected prior to the initiation of consolidation.
- Adequate organ function defined as:
- Hepatic: AST and ALT \< 3 x upper limit of institutional normal; ALT ≤ 3 x ULN for age; total bilirubin ≤ 1.5 x ULN for age, if baseline was normal, \> 1.0 1.5 x baseline if baseline was abnormal
- Cardiac: shortening fraction ≥ 27% or ejection fraction ≥ 45%, no clinical congestive heart failure
- Pulmonary: no evidence of dyspnea at rest and norequirement for supplemental oxygen
- Renal: Creatinine clearance or GFR \> 60 mL/min/1.73m\^2. If a creatinine clearance is performed at end induction and the result is \< 100 ml/min/1.73m\^2, a GFR must then be performed using a nuclear blood sampling method or iothalamate clearance method. Camera method is NOT allowed as measure of GFR prior to or during Consolidation therapy for patients with GFR or creatinine clearance of \< 100 ml/min/1.73m\^2
- Recovery from acute toxicities of last cycle of induction chemotherapy
- Appropriate written consent - adult or parent/guardian if patient is \< 18 years of age and minor information sheet if patient is \> 8 years of age
Where
- Minneapolis, Minnesota
Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
