- Patient must qualify with a study specific HLA typing assay.
Haematological parameters:
- Absolute neutrophil count (ANC) ≥ 1,000/μl

Evaluation of the safety and tolerability of WT2725 Dosing Emulsion based on the occurrence of DLT and AEs The safety and tolerability of WT2725 Dosing Emulsion will be evaluated based on the occurrence of DLT and AEs, and the findings from clinical laboratory tests, vital signs measurements, body weight measurements, and electrocardiogram (ECG) results.
The incidence of DLT will be evaluated during the DLT Evaluation Period, which extends from the day of the first dose to just prior to the fifth dose of study drug (Days 1 to 29).
No more than 4 doses of study drug will be administered during the DLT Evaluation Period.

Antitumor Responses to WT2725 Based on the Immune-related Response Criteria (irRC)
Time Frame: Day 1 - within 28 days after last dose
|
Tumor response, as evaluated according to irRC, was based on total measurable tumor burden in patients with solid tumors (ie, non-AML patients).
Tumor assessments will be conducted during screening, and then every 8 weeks after the first dose of study drug.
All tumor assessments may be performed within ±7 days of the scheduled assessment.
All patients should complete an End of Study visit within 28 days after the last dose of study drug and prior to the start of alternate antineoplastic therapy.

Immune Response to WT2725
Time Frame: Day 1 - within 28 days after last dose
|
The modified IWG response criteria were used to assess drug activity in AML patients.
Tumor assessments will be conducted during screening, and then every 8 weeks after the first dose of study drug.
All tumor assessments may be performed within ±7 days of the scheduled assessment.
All patients should complete an End of Study visit within 28 days after the last dose of study drug and prior to the start of alternate antineoplastic therapy.
