Study Summary

This phase I trial is studying the side effects and best dose of 1-methyl-D-tryptophan in treating patients with metastatic or refractory solid tumors that cannot be removed by surgery. Biological therapies, such as 1-methyl-D-tryptophan, may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by stimulating the immune system.

Primary Outcome

All patients who receive any amount of the study drug will be evaluable for toxicity.
