criteria above and are not known to be refractory to red cell or platelet
transfusions

however, platelet count has to be >= 20,000/mm^3 (may receive platelet
transfusions)

110 U/L for patients with solid tumors OR SGPT (ALT) =< 225 U/L for patients with
leukemias (for the purpose of this study, the ULN for SGPT is 45 U/L)

0 or 1 of the every other day schedule

- No BSA restrictions apply to patients enrolling on higher dose levels

- No BSA restrictions apply to patients enrolling on any dose level of the weekly
schedule

- Patients with seizure disorder may be enrolled if on non-enzyme-inducing
anticonvulsants and well controlled

- Patients with known type I or type II diabetes mellitus are not eligible

- Patients who, in the opinion of the investigator, may not be able to comply with the
safety monitoring requirements of the study are not eligible

- Patients must have fully recovered from the acute toxic effects of all prior
anti-cancer chemotherapy

- Patients with solid tumors must not have received myelosuppressive chemotherapy
within 3 weeks of enrollment onto this study (6 weeks if prior nitrosourea)

- Patients with leukemia who relapse while receiving standard maintenance chemotherapy
will not be required to have a waiting period before enrollment onto this study

- Patients with leukemia who relapse while they are not receiving standard maintenance
therapy, must have fully recovered from all acute toxic effects of prior therapy

prior to the start of MK-2206

- At least 14 days after the last dose of a long-acting growth factor (e.g., Neulasta)
or 7 days for short-acting

- For agents that have known adverse events occurring beyond 7 days after
administration, this period must be extended beyond the time during which
adverse events are known to occur (the duration of this interval must be
