JVRS-100 for the Treatment of Patients With Relapsed or Refractory Leukemia

April 3, 2019 updated by: David F. Claxton, MD, Milton S. Hershey Medical Center

A Phase I Trial of the Immunostimulant JVRS-100 for the Treatment of Patients With Relapsed or Refractory Leukemia

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Arms and Interventions

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: 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.
Drug: JVRS-100
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
Other Names:
  • Cationic liposome
  • Plasmid DNA complex
Drug: JVRS-100
Change to Stage 2 with starting dose of 4.0 µg/Kg D1,8,15 if no toxicity level by Level 5.
Other Names:
  • Cationic liposome
  • Plasmid DNA complex
Experimental: 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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Tolerability of JVRS-100
Time Frame: Day 30 of cycle #1
Toxicities will be assessed on day 30 of cycle 1. Establish dose limiting toxicity and a maximum tolerated dose recommended Phase 2 dose.
Day 30 of cycle #1

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Define parameters of immune activation after JVRS-100 therapy.
Time Frame: Day 30 of cycle #1
Activation of peripheral blood cells including T-cell subsets, CD4+ and CD8+ cells, B-cells, and NK cells will be studied for activation markers including cell surface phenotypic changes, and expression of intracellular cytokines. Changes in circulating cytokine concentrations will be studied, as will functional properties of circulating immune effector and activating cells.
Day 30 of cycle #1
