A Maintenance Protocol of Sirolimus in Combination With Metronomic Chemotherapy in Children With High-Risk Solid Tumors
Emory University
Summary
The primary objective of this 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.
Description
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…
