Phase 1 Study of VAX014 for Advanced Solid Tumors

This study is testing VAX014, a non-infectious, non-replicating bacterial treatment, for advanced solid tumors. It will be given directly into the tumor (intratumorally). The study aims to find the safest dose of VAX014 alone, and then test it in combination with either nivolumab or pembrolizumab, which are checkpoint inhibitors (drugs that help your immune system fight cancer). You could join if you are 18 or older, have an advanced solid tumor that has progressed after other treatments or if you can't tolerate standard treatments. The main goals are to see how safe VAX014 is and what dose works best. The current recruitment status is unclear.

Study design
This is a Phase 1 study with an unclear status, planning to enroll 48 participants. It will first test VAX014 alone to find the best dose, then combine it with nivolumab or pembrolizumab.
What's involved
You would receive weekly injections of VAX014 for the first 8 weeks. The study will monitor your safety and tolerability for an average of 20 weeks.
Compensation
Not stated in the trial record.
Follow-up
Your safety and tolerability will be monitored through study completion, which is an average of 20 weeks.

  • Maximum tolerated dose (MTD) of VAX014up to 21 days

    The MTD will be defined as the dose level at which at most one of six patients experiences a dose limiting toxicity (DLT) after 21 days of treatment have occurred, with the next higher dose having at least 2/3 or 2/6 patients experiencing a DLT

  • Incidence of Treatment-Emergency Adverse Events (Safety and Tolerability)Through study completion, an average of 20 weeks

    Toxicities will be assessed in each subject by tracking the occurrence of graded Adverse Events (AEs). AEs will be graded according to the National Cancer Institute Common Terminology for Adverse Events (NCI CTCAE) v5.0

  • Recommended Phase 2 Dose (RP2D) for single agent intratumoral VAX014up to 5 weeks

    The RP2D will be determined following the determination of the MTD and with agreement by the Safety Review Committee

  • Acceptable dose of VAX014 in combination with PD-1 Inhibitor3 months

    Determine the acceptable dose of VAX014 when used in combination with Investigator's choice of nivolumab or pembrolizumab

  • Evaluation of efficacy of VAX014 in combination with either nivolumab or pembrolizumab18 months

    Evaluate efficacy including overall response rate (ORR), response of injected tumor(s) of VAX014 in combination with Investigator's choice of nivolumab or pembrolizumab
