NCT ID: NCT00860522

Last Updated: 2019-04-05

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1
• Total Enrollment: 11 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2009-03-01
• Study Completion Date: 2017-02-20

Brief Summary

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.

Detailed Description

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, cohorts of three will be treated at each dose level however doses will be doubled from level to 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. The Principal Investigator will assign dose level to be administered to all patients.

Study Groups

Phase I

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.

Group Type: EXPERIMENTAL

JVRS-100

Intervention Type: DRUG

Level 1: 0.5 µg/Kg D1,8,15; Level 2: 1.0 µg/Kg D1,8,15; Level 3:2.0 µg/Kg 1,15; Level 4: 2.0 µg/Kg D1,8,15; Level 5: 4.0 µg/Kg D1,15

Phase II

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.

Group Type: EXPERIMENTAL

JVRS-100

Intervention Type: DRUG

Change to Stage 2 with starting dose of 4.0 µg/Kg D1,8,15 if no toxicity level by Level 5.
