EWOC is targeted with TTL ≤ 0.33.

**

EWOC-NETS is targeted with different TNETS for Scenario 1 (0.476), 2 (0.41), 3 (0.526), 4 (0.25), and 5 (0.69), respectively.

***

:All the 6 pre-specified dose levels are determined to be over toxic and the recommend MTD from simulation trial is a dose lower than the lowest pre-specified dose level (level 1).

****

: All the 6 pre-specified dose levels are determined to be under toxic and the recommend MTD from simulation trial is a dose higher than the highest pre-specified dose level (level 6).
