| Solid Tumor | Drug: Sirolimus Drug: Cyclophosphamide Drug: Etoposide Drug: Celecoxib | Phase 2 |
Sirolimus, also known as rapamycin, is a potent immunosuppressive drug. Due to its profound immunosuppressive actions, sirolimus was initially developed and received regulatory approval for the indication of prevention of allograft rejection following solid organ transplant. Sirolimus also possesses anti-tumor activity through its anti-proliferative effect, by the inhibition of translation of key messenger ribonucleic acids (mRNAs) into proteins required for cell cycle progression from the G1 to the S phase.
Palliative care with the use of antiangiogenic metronomic chemotherapy in the form of low-dose daily oral administration of etoposide and cyclophosphamide in combination with antiangiogenic agents such as celecoxib, is feasible and well-tolerated in children with refractory solid tumors
Sirolimus is used orally in adults and children for the prevention of allograft rejection following solid organ transplant. The Pediatric Preclinical Testing Program (PPTP) performed testing of sirolimus as a single agent against an in vitro panel of pediatric cell lines, as well as against in vivo pediatric tumor panels. Sirolimus exhibited variable inhibition of cell line growth, ranging from 19% to 85% (median 49%).
This study has three cohorts: a prospective cohort of patients with high-risk extracranial solid tumor, a prospective cohort of patients with recurrent solid tumors (any histology) in second complete remission, and a historical control cohort of patients matched on diagnosis, age, metastatic site, and date of diagnosis. The matched historical controls will be obtained from the same treating institution as the corresponding case to account for institutional differences in treatment and supportive care. The primary objective of the study is to improve the 2-year progression-free survival in children with high-risk solid tumors who are administered a maintenance regimen with continuous sirolimus administered on a backbone of metronomic chemotherapy following the completion of "standard" therapy, as compared to high-risk solid tumor patients treated with observation alone following completion of "standard" therapy.

Experimental: Maintenance Chemotherapy Regimen
Participants with metastatic osteosarcoma, metastatic Ewing sarcoma, high-risk rhabdomyosarcoma, metastatic non-rhabdomyosarcoma soft tissue sarcoma (NRSTS), desmoplastic small round cell tumor (DSRCT), and malignant rhabdoid tumor (MRT) in first complete remission (cohort 1) or participants with recurrent solid tumors (any histology) in second complete remission (cohort 2), receiving a maintenance chemotherapy regimen administered as a 12-month course of continuous sirolimus with celecoxib and low-dose oral etoposide alternating every 21 days with low-dose oral cyclophosphamide following the completion of "standard" therapy.
|
Drug: Sirolimus
Sirolimus is given at a dose of 2 mg/m2 once daily. The amber oral dose syringe should be used to withdraw the prescribed amount of sirolimus oral solution from the bottle. The solution can be drunk or administered at once to assure delivery of all of the medication. It is safe for administration through a nasogastric or G-tube. For tablets, the tablet should not be crushed, split, or otherwise altered. As with the liquid dosing form, the tablets should be given within two hours each day and should be at consistent intervals with regard to meals.
Other Names:
Drug: Cyclophosphamide A synthetic antineoplastic drug chemically related to the nitrogen mustards. The drug is administered orally daily, in the formulation appropriate for age. The solution should be diluted in 20-30 ml of appropriate liquid before administration through nasogastric (NG) tube or gastrostomy (G) tube, with adequate flushing after administration to prevent obstruction of the feeding tube. Other Name: Cytoxan Drug: Etoposide A semisynthetic derivative of podophyllotoxin which functions as mitotic inhibitor but does not interfere with microtubular assembly. The drug is administered orally daily, in the formulation appropriate for age.
Other Names:
Drug: Celecoxib The drug is administered orally daily, in the formulation appropriate for age.The solution is safe for administration through a nasogastric or G-tube.
Other Name: Celebrex |

No Intervention: Historical Control Cohort Receiving Standard Therapy
This study arm is a historical control cohort of patients matched with cohort 1 on diagnosis, age, metastatic site, and date of diagnosis. The matched historical controls will be obtained from the same treating institution as the corresponding case to account for institutional differences in treatment and supportive care. Patients in the historical control cohort received standard therapy.

- Number of patients who come off protocol therapy due to toxicity or non-compliance [ Time Frame: up to 2 years ]Feasibility of completion of a 12-month course of maintenance chemotherapy following completion of "standard" therapy will be evaluated by number of patients who come off protocol therapy due to toxicity or non-compliance.
