				        	Objective Aiming at the problem of delayed therapeutic effect of tumor targeting agents and cellular immunotherapy,an innovative TITE(e)-U-Keyboard design is established based on the framework of phaseⅠ/Ⅱclinical trial design.Methods Approximated binomial likelihood method was used to incorporate the unobserved efficacy outcome information and construct approximated distribution to assist decision making.TITE(e)-U-Keyboard was compared with theⅠ/Ⅱ trial design method(U-BOIN、BOIN12)from multiple perspectives.Results Simulation results show that the accuracy of OBD selection and the number of patients allocated at optimal dose of the three methods were similar,but TITE(e)-U-Keyboard requires the shortest trial duration.Sensitivity analysis shows that the effectiveness evaluation window has an effect on the TITE(e)-U-Keyboard duration,which increases with the increase of effectiveness evaluation window.Conclusion TITE(e)-U-Keyboard significantly reduces the trial duration while maintaining good simulation performance and it can address the problem of delayed treatment effects in phase Ⅰ/Ⅱ clinical trials,thus accelerating the clinical trial process.
