Summary
Brief summary (as posted)
This is a Phase 1, open-label, dose escalation study of JVRS-100. The study will proceed in 2 stages to minimize the number of patients treated at doses substantially below the recommended phase 2 dose. In stage 1, an accelerated titration schema will be followed with one patient at each dose level. Stage 2 will commence after a dose limiting toxicity is observed in stage 1 or after the maximum dose for stage 1 is reached. Stage 2 will follow a modified Fibonacci schema with 3-6 subjects at each dose level until a recommended phase 2 dose is determined. The cohort will then be expanded to a maximum of 12 patients to more fully evaluate the recommended phase 2 dose.

- description
- Three patients will be enrolled at dose Level 1. If the patient does not completed the three infusion of JVRS-100 during cycle 1 for reason other than toxicity, another patient will be accrued at the same dose level.

- Phase II
- description
- 3 patients will be enrolled at a given dose level. If one of these patients experiences a dose limiting toxicity, an additional 3 patients will be enrolled at the given dose level. If the 1st 2 subjects enrolled and treated at a given dose experience dose limiting toxicities, no additional subjects will be enrolled at that dose. Dose escalation may proceed if \< 2/6 patients at a given dose level experience a LDT. If ≥ 2/6 patients experience a DLT at a given dose level, the next lower dose level will be considered the RP2D. If a patient does not complete the 3 infusions of JVRS-100 during Cycle 1 for reasons other than toxicity, another patient will be accrued at the same dose level. Once the RP2D is established, the cohort will be expanded to a total of 12 patients.
