Clinical Trial Summary

This is a multicenter, open-label study conducted in 3 phases: Dose escalation stage: The stage contain 4 cohorts, each cohort divided into 2 groups （group A, single dose and Group B, multiple dose）.Dose escalation will use a 3+3 design to evaluate escalating doses of T3011.Cohorts of three subjects will be enrolled at each T3011 dose level with expansion to six subjects, if necessary, to assess toxicity. Total enrollment will depend on the toxicities observed, with approximately 4-24 evaluable subjects enrolled in dose escalation stage. Dose extension stage: The SMC will evaluate the available safety and preliminary efficacy data and initiate dose-expansion studies for the appropriate indications Phase IIa: To explore the safety of intravenous administration and expand the study in other indications. the stage will be carried out gradually based on the data obtained from the phase I study.

Description:

This is a multicenter, open-label study conducted in 3 phases: Dose escalation stage: The stage contains 4 cohorts, divided into cohort 1 (1x106PFU/ dose), cohort 2 (1x107PFU/ dose), cohort 3 (1x108PFU/ dose) and cohort 4 (3x108PFU/ dose). Each cohort divided into 2 groups （group A, single dose and Group B, multiple dose）.Dose escalation will use a 3+3 design to evaluate escalating doses of T3011. At any dose level, if no DLT occurs among the first 3 subjects, then escalation to the next dose level may proceed, with the approval of the SMC. If 1 DLT occurs in the first 1 to 3 subjects, the dose level will expand to a maximum of 6 subjects. If no DLT occurs among the additional subjects, then escalation to the next dose level may proceed, with the approval of the SMC. If 2 or more DLTs occur within a cohort, then that dose level will be above the maximum tolerated dose (MTD) (the highest dose where no more than 1 of 6 subjects has experienced a DLT), and new subjects will be enrolled at the previous lower (tolerated) dose level until that cohort has 6 subjects. This lower dose level will be considered the MTD if ≤ 1 in 6 subjects has a DLT. At the end of dose escalation, the SMC will recommend a dose (the recommended phase 2 dose [RP2D]) of T3011 to be used in phase 2a expansion study based upon MTD identification, cumulative safety, pharmacokinetic (PK), efficacy, and pharmacodynamic data. Total enrollment will depend on the toxicities observed, with approximately 4-24 evaluable subjects enrolled in dose escalation stage. In group A, participant will receive a single dose and the DLT evaluation period is 14 days. In group B, Participants will receive administration at D1/D4/D8 of every cycle. The DLT evaluation period will be the first 21-day Cycle in group B. Tumor evaluation was performed every two cycles. The maximum treatment period should not exceed 4 cycles. Group B of cohort X was enrolled only after the DLT assessed for group A of cohort X and SMC approval to proceed to the next cohort assessment. Dose extension stage: The SMC will evaluate the available safety and preliminary efficacy data and initiate dose-expansion studies for the appropriate indications Phase IIa: To explore the safety of intravenous administration and expand the study in other indications. the stage will be carried out gradually based on the data obtained from the phase I study.
