Description of intervention(s) / exposure
Treatment: Drugs - DFMO
Treatment: Drugs - Celecoxib
Treatment: Drugs - Cyclophosphamide
Treatment: Drugs - Topotecan

Experimental: DFMO, Celecoxib, Cyclophosphamide & Topotecan - 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.

Summary
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.
