摘要: Purpose A dose-escalation phase I and pharmacokinetic study of the farnesyltransferase inhibitor lonafarnib (SCH66336) was conducted in children with recurrent or progressive CNS tumors. Primary objectives were to estimate maximum-tolerated dose (MTD) describe dose-limiting toxicities (DLTs) pharmacokinetics lonafarnib. Farnesylation inhibition HDJ-2 peripheral blood also measured. Patients Methods Lonafarnib administered orally twice daily at levels 70, 90, 115, 150, 200 mg/m2/dose bid. modified continual reassessment method (CRM) used MTD based on actual dosages observed during initial 4 weeks treatment. Results Fifty-three brain tumors enrolled, a median age 12.2 years (range, 3.9 19.5 years). Dose-limiting pneumonitis myelosuppression three patients level. relatively constant...
