05 and c2 = 1800, respectively. g(c2) is the MTD associated with the maximum anticipated concentration of anti-SEA. Since the probability of DLT at a given dose is a decreasing function of anti-SEA, we have U2 < U1. Thus, the parameter space associated with N = [U1, U2] was taken to be V = {(x, y): 0 V x V u, 0 V y V x}. 5), ln(1000)]. 8. Monitoring Safety and Efficacy in Phase I and II Trials Upon completion of the phase I trial a decision is made to either remove the treatment from further investigation or to progress to a phase II evaluation of treatment efficacy.

20). 80. We used Simon’s optimal two-stage design (1989). 80. The rationale is that it is often attractive to investigators to minimize sample size when the treatment is unsuccessful, but that sample size is less of concern when the treatment is successful. Patients were to be entered in two stages, with the first (minimum) dose level of the preparative regimen stopped after the first stage if there were not a sufficient number of engraftments. If, among the first 9 patients treated, 7 or fewer engrafted, H0 would be accepted and the trial would stop.
