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.
N2012-01: Phase 1 Study of Difluoromethylornithine (DFMO) and Celecoxib With Cyclophosphamide/Topotecan for Patients With Relapsed or Refractory Neuroblastoma
Patients must be> 2 years and < 30 years of age when registered on study.
Patients must have recurrent/progressive high-risk neuroblastoma, refractory high-risk neuroblastoma that had less than a partial response to standard treatment or persistent high-risk neuroblastoma that had at least a partial response to standard treatment.
All patients must have at least ONE site of evaluable disease.
Patients must have adequate heart, kidney, liver and bone marrow function.
Patients who have bone marrow disease must still have adequate bone marrow function to enter the study.
Patients with other ongoing serious medical issues must be approved by the study chair prior to registration.
You CAN'T join if...
