WT2725

Vice President Clinical Development and Medical Affairs, MD

This clinical study is designed to evaluate the safety, immunogenicity and antitumor activity of WT2725. WT2725 will be administered to patients with advanced malignancies known to overexpress WT1

Treatment with other WT1 vaccines in clinical trials has shown evidence of immunogenicity and clinical response in various malignancies.

This study will assist with determining which dose level(s) to use in future clinical studies and will evaluate both clinical and immunological response.

Clinical Study of WT2725 in Patients With Advanced Malignancies

Initial Phase 1 Study of WT2725 in Patients With Advanced Malignancies

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.

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.

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.

Serious adverse events (SAEs) will be defined as: • AEs that occurred on or after the first dose of study drug and on or before the 30th day after the last dose of study drug, • AEs with a missing start date and a stop date on or after the first dose of study drug, or • AEs with both a missing start and stop date.

Safety Population (defined as all enrolled patients who received at least one dose of study drug.)

Occurrence of Dose-limiting Toxicities and Adverse Events

The MTD could not be established for this study as no DLTs occurred at doses up to and including 27.0 mg

Maximum Tolerated Dose (MTD) of WT2725 Based on the Evaluation of Dose-limiting Toxicity (DLT)

Efficacy irRC population: including all the patients in the Safety population who are not AML patients and whose lesions are measureable and have at least one posttreatment assessment.

Antitumor Responses to WT2725 Based on the Immune-related Response Criteria (irRC)

Efficacy population for modified IWG response: includes all the AML patients in the Safety population who have \>5% marrow blasts or \>50 copy/μｇRNA of quantitative RT-PCR for WT1 transcript before the first date/time of study drug and who have at least one posttreatment assessment.
