Outcome Measures
Primary Outcomes (1)
Number of participants with event free survival (EFS) during study
To evaluate the efficacy of difluoromethylornithine (DFMO) in combination with etoposide in patients with relapsed/refractory neuroblastoma, based upon: o Event free survival (EFS) from time of enrollment.
2 years plus 5 years follow up
Secondary Outcomes (3)
Length of time that participants experience Overall Survival (OS)
7 years
Determine the Overall Response Rate (ORR) of Participants using INSS Response Evaluation Criteria.
2 years
Number of Participants with Adverse Events as a Measure of Safety and Tolerability
2 years plus 30 days
Study Arms (1)
Eflornithine (DFMO)
EXPERIMENTALIn this study subjects will receive six 21-day cycles of Etoposide and DFMO followed by an additional 630 days of DFMO alone. Etoposide will be given at 50 mg/m2/dose PO daily for the first 14 days of each 21 days until 6 cycles of etoposide are completed. DFMO (difluoromethylornithine) will be given at a dose of 1000 mg/m2 BID on each day of study.
Interventions
DFMO (difluoromethylornithine) will be given at a dose of 1000 mg/m2 BID on each day of study.
Eligibility Criteria
You may qualify if:
- All patients must have a pathologically confirmed diagnosis of neuroblastoma, ≤ 30.99 years of age with history of relapsed/refractory neuroblastoma.
- All patients must have completed upfront therapy with at least 4 cycles of aggressive multi-drug chemotherapy.
- Specific Criteria by Arm:
- Arms 1 and 2:
- Subjects with no active disease:
- i. No evidence of residual disease by CT/MRI and MIBG scan (or PET for patients who have a history of MIBG non-avid disease).
- o Note: Patients with residual masses detected by CT/MRI may be considered in CR if their MIBG is negative or if MIBG positive and evaluated by PET and found to have negative PET scans; biopsy confirmation may be considered if there is still reasonable concern for persistent disease but is not required.
- ii. No evidence of disease metastatic to bone marrow.
- Arm 3 \[CLOSED TO ENROLLMENT\]:
- Measurable or evaluable disease, including at least one of the following:
- Measurable tumor by CT or MRI; or a positive MIBG and PET; or positive bone marrow biopsy/aspirate in at least one site.
- Timing from prior therapy: Enrollment (first dose of DFMO) no later than 60 days from last dose of the most recent therapy.
- Subjects must have fully recovered from the acute toxic effects of all prior anti- cancer chemotherapy and be within the following timelines:
- Myelosuppressive chemotherapy: Must not have received within 2 weeks of enrollment onto this study (6 weeks if prior nitrosourea).
- Hematopoietic growth factors: At least 5 days since the completion of therapy with a growth factor.
- +18 more criteria
You may not qualify if:
- BSA of \<0.25 m2.
- Subjects that received DFMO at a dose higher than 1000mg/m2 BID prior to this study are not eligible.
- Subjects that received a dose of DFMO in combination with etoposide are not eligible.
- Investigational Drugs: Subjects who are currently receiving another investigational drug are excluded from participation.
- Anti-cancer Agents: Subjects who are currently receiving other anticancer agents are not eligible. Subjects must have fully recovered from hematological and bone marrow suppression effects of prior chemotherapy.
- Infection: Subjects who have an uncontrolled infection are not eligible until the infection is judged to be well controlled in the opinion of the investigator.
- Subjects who, in the opinion of the investigator, may not be able to comply with the safety monitoring requirements of the study, or in whom compliance is likely to be suboptimal, should be excluded.
