          -  Creatinine clearance; calculated creatinine clearance (CrCl) >= 30 mL/min and < 60
             mL/min (Cockroft-Gault) unless the patient qualified based on hearing loss or
             neuropathy

             (hormonal or barrier method of birth control; abstinence) prior to study entry and for
             the duration of study participation; should a woman become pregnant or suspect she is
             pregnant while she or her partner is participating in this study, she should inform
             her treating physician immediately; men treated or enrolled on this protocol must also
             agree to use adequate contraception prior to the study, for the duration of study
