Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intervention = Investigational Product = T3011, a genetically modified oncolytic virus.

Participants will receive T3011 at the assigned dose level by intratumoural injection commencing on W1D1, and approximately every 14 days thereafter (ie: W3D1, W5D1 etc) for up to 2 years (unless disease progression, unacceptable toxicity, death or withdrawal of consent).

Part 1 – Dose Escalation
The starting dose of T3011 is 1.0 × 10^6 PFU/mL with the volume injected intratumourally based on tumour size, but not exceeding a total of 4 mls for each visit for all tumours combined.

The study uses a 3+3 dose escalation design to evaluate escalating doses of T3011 monotherapy. Three additional doses are planned to be tested (1.0 × 10^7, 5.0 × 10^7, and 1 × 10^8 PFU/ml). At any dose level, if no dose-limiting toxicity (DLT) occurs among the first 3 participants, then escalation to the next dose level may proceed if approved by the Safety Review committee (SRC). If 1 DLT occurs in the first 1 to 3 participants, the dose level will expand to a maximum of 6 participants. If no DLT occurs among the additional participants, then escalation to the next dose level may proceed if approved by the SRC. The non-tolerated dose (NTD) is the dose level at which 2 or more participants experience a DLT during the DLT evaluation period. The maximum tolerated dose (MTD) will be defined as the dose level immediately below the NTD. At least 6 participants will be treated at the MTD before expansion to Part 2 (Dose Expansion) with additional participants treated with a dose selected by the SRC.

Safety
Statistical methods / analysis
Sample Size Determination
No formal hypothesis testing is planned. The number of participants in each period of the study is based on safety and tolerability. Part 1 (Dose Escalation) will enrol approximately up to 24 participants using a 3+3 dose escalation design without intraparticipant dose escalation. Part 2 (Dose Expansion) will enrol approximately up to 30 participants to be apportioned among disease-specific cohorts.

Statistical methods will be primarily descriptive in nature. No hypothesis will be formally tested. Categorical variables will be summarised using numbers and percentages. Continuous variables will be summarised by total number (n), mean, standard deviation, median, and range (minimum and maximum). The dose escalation period and the dose expansion period will be analysed separately. Within each study period, the analyses will be conducted by dose group. Across different study periods, participants on the same dose level may be pooled together if specified.
