Aflac ST0901 CHOANOME - Sirolimus in Solid Tumors (Aflac ST0901)
The best treatment for recurrent cancers or those that do not respond to therapies is not known. Typically, patients with these cancers receive a combination of cancer drugs (chemotherapy), surgery, or radiation therapy. These treatments can prolong their life but may not offer a long-term cure.
This study proposes using a drug called Sirolimus in combination with common chemotherapy drugs to treat patients with recurrent and refractory solid tumors. Sirolimus has been found to inhibit cell growth and to have anti-tumor activity in pediatric solid tumors in previous studies and, therefore, has the potential to increase the effectiveness of the chemotherapy drugs when given together.
This study wil investigate the highest dose of Sirolimus that can be given orally with other oral chemotherapy drugs. Cohorts of 2 subjects will be started at the minimum dose. The dose will be increased in the next 2 subjects as long as there were no major reactions in the previous groups. This study will also seek to learn more about the side effects of sirolimus when used in this combination and what effects the drug has on the white cells and the immune system. Successful use of this drug will impact the cancer population greatly by providing an increased chance of survival to those with resistant or recurrent cancers.

- Maximum tolerated dose (MTD) [ Time Frame: 2 years after treatment starts ]estimate the maximum tolerated dose (MTD) and recommended Phase II dose of sirolimus administered orally once daily for 42 days in combination with metronomic chemotherapy in children with recurrent or refractory solid tumors.
- define and describe toxicities of sirolimus [ Time Frame: 2 years post treatment ]To define and describe the toxicities of sirolimus administered in combination with metronomic chemotherapy administered according to this schedule.
- anti-tumor activity of sirolimus [ Time Frame: 2 years post treatment ]To assess the antitumor activity of sirolimus administered in combination with metronomic chemotherapy to children with recurrent and refractory solid tumors within the confines of a Phase I study.
- evaluate correlation of p70S6 kinase activity [ Time Frame: 2 years post treatment ]To evaluate the correlation of p70S6 kinase activity inhibition with tumor response.
- evaluate risk of infection [ Time Frame: 2 years post treatment ]To evaluate the effect of this combination therapy on lymphocyte subsets and memory T-cells, and to correlate that with risk of infection.
