摘要: Vincristine sulfate liposome injection (VSLI,) is a sphingomyelin and cholesterol nanoparticle formulation of vincristine (VCR) that was designed to overcome the dosing pharmacokinetic limitations standard VCR. In contrast rapid CL wide tissue distribution non-liposomal VCR, VSLI circulates in plasma for prolonged period time, with slow 345 mL/h relatively small Vd 3,570 mL. This facilitates enhanced tumor-tissue delivery The maximum tolerated dose VSLI, 2.25 mg/m(2) once per week without cap, enables individual cumulative VCR exposure unachievable at its labeled 1.4 mg/m(2) . associated dose-dependent peripheral neurotoxicity albeit doses are two three times intensification correlated an increased probability overall response strong trend towards complete adults relapsed and/or refractory acute lymphoblastic leukemia. Overall, improves therapeutic index by facilitating while maintaining predictable manageable safety profile.
