Summary
This phase I trial studies the side effects and best dose of nab-paclitaxel when given together with gemcitabine hydrochloride in treating pediatric participants with solid tumors that are newly-diagnostic, have come back (relapsed), or do not respond to treatment (refractory). Nab-paclitaxel may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as gemcitabine hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells, or by stopping them from dividing, or by stopping them from spreading. Giving nab-paclitaxel in combination with gemcitabine hydrochloride, may work better in treating pediatric participants with solid tumors.
