Description
Phase I: Phase I dose escalation The accelerated titration (ATD) incorporated with Bayesian Optimal Interval design (BOIN) will be used to assess the DLT, safety, tolerability, MTD and furthermore, to establish the RP2D. DLT assessment is only applicable to phase I dose escalation. Eligible patients will be enrolled in the ascending dose until MTD/RP2D is established. Phase I dose extension During the dose escalation phase, a dose extension with additional patients will be included in order to further evaluate the tolerability, pharmacokinetics, and efficacy at doses that have been evaluate…
