Four patients were treated before and three patients after the study was amended to exclude grade 3 and 4 electrolyte abnormalities that resolved to at least grade 2 within 7 days
One patient was not assessable for toxicity because of early tumor progression
dose-limiting toxicity
These toxicities were not considered dose-limiting toxicities according to the study criteria
