The highest safest doses are determined by increasing the doses of cisplatin and KML001 in successive groups of patients until at least some of them have serious side effects. All patients on this study will receive the same dose of cisplatin, which is known to have antitumor effects. The doses of KML001 will be increased in successive groups of patients. It is possible that those entering the study early may receive suboptimal doses of KML001. At the end of the study we hope to determine the appropriate dose of the KML001 in combination with cisplatin, learn about its side effects and understand how the body metabolizes the drug.
