N2012-01: Phase 1 Study of Difluoromethylornithine (DFMO) and Celecoxib With Cyclophosphamide/Topotecan
- Conditions
- Neuroblastoma
- Interventions
- Registration Number
- NCT02030964
- Lead Sponsor
- New Approaches to Neuroblastoma Therapy Consortium
- Brief Summary
This study will combine an oral drug called DFMO with celecoxib (also oral) and two IV chemotherapy medicines called cyclophosphamide and topotecan.
* To find the highest dose of DFMO that can be given with celecoxib, cyclophosphamide and topotecan without causing severe side effects.
* To find out the side effects seen by giving DFMO at different dose levels with celecoxib, cyclophosphamide and topotecan.
* To measure the levels of DFMO in the blood at different dose levels.
* To determine if your tumor gets smaller after treatment with DFMO, celecoxib, cyclophosphamide and topotecan.
* To determine if specific gene changes in you or your tumor makes you more prone to side effects or affects your tumor's response to the combination of DFMO, celecoxib, cyclophosphamide and topotecan.
* To determine if the amount of normal chemicals in your body called polyamines go down in response to DFMO, celecoxib, cyclophosphamide and topotecan, and whether you are more likely to have a good response to the treatment if they do.

Group Intervention Description DFMO, Celecoxib, Cyclophosphamide & Topotecan DFMO Reconstituted DFMO powder by mouth for 14 days and celecoxib capsule by mouth daily in each cycle. Cyclophosphamide and Topotecan IV on days 8-12 in cycle 1 and days 1-5 of cycles 2-17. Patients may continue for up to 17 cycles as long as therapy is tolerated (no DLT) and disease progression does not occur (SD or better). \*Cycle 1 will include a 7 day lead-in with DFMO and celecoxib to deplete tumor polyamines.

- Primary Outcome Measures
Name Time Method Number of participants with adverse events as a measure of safety and tolerability. Approximately 1 year The standard 3+3 design for dose escalation will be utilized. 3-6 patients will enroll at each of 4 dose levels, but enrollment to a dosing cohort will cease after observation of DLTs in 2 or more patients. A minimum of 2 to a maximum of 24 patients will be enrolled assuming all 4 dose levels require 6 patients before an MTD is determined. A total of 12 patients may be enrolled at the study defined MTD (including those used to define the MTD) to provide additional adverse event data for safety evaluation.
