A Safety and Immunogenicity Phase IC Study of CryJ2 -DNA-LAMP Plasmid Vaccine for Assessment of Intradermal (ID) Route of Administration Using the Biojector 2000 Device

Summary

This is a research study of a vaccine for allergy to Japanese Red Cedar. The vaccine is called CryJ2-DNA-LAMP Plasmid vaccine. This research study will determine how the vaccine is tolerated and how research participants respond to the vaccine using a different route of administration, the Intradermal (ID) route. CryJ2-DNA-LAMP Plasmid vaccine is investigational, which means it is not approved for use by the United States Food and Drug Administration (FDA) but is available in research studies like this one.

The study is a Phase IC study to assess and evaluate the safety and immunological responses to therapeutic doses of a dosing regimen of 1.08 mg and 2.16 mg of CryJ2-DNA-LAMP plasmid vaccine delivered intradermally (ID) using the Biojector 2000 device, to be administered every 14 days in subjects with atopic sensitivity to Japanese Red Cedar pollen, identified by skin test reactivity to this pollen. The protocol has three subject cohorts: a Cohort 1: composed of atopic and non-atopic subjects (half atopic and half non-atopic), who will only receive saline control administered using the Biojector 2000 device; a Cohort 2: atopic subjects, who will receive 2.16 mg per dose in a four (4) dose regimen using a Biojector 2000 device; and a Cohort 3: atopic subjects, who will receive 1.08 mg per dose in a four (4) dose regimen vaccinated using a Biojector 2000 device.The study will be conducted at 1 study center. Subjects are enrolled in the trial for a period of 132 days. The objectives of the statistical analyses are to establish the safety and to explore the immunogenicity of the LAMP-vax vaccine using a different route of administration, the Intradermal (ID) route. All statistical analyses conducted on the data from this trial will be exploratory in nature.

The primary objective of this Phase IC Study is to evaluate the safety and immunological responses of therapeutic doses and the dosing regimen of CryJ2-DNA-LAMP plasmid vaccine delivered intradermally (ID) using the Biojector 2000 device.

Interventions

BIOLOGICAL

CryJ2-DNA-LAMP plasmid vaccine by intradermal injection

Immunomic Therapeutics Inc. CryJ2-DNA-LAMP vaccine is a frozen product formulated in physiological saline and contains no preservative. The study product is packaged in a 1 ml volume in a 3 ml glass vial, with label complying with FDA requirements. Subjects will receive CryJ2-DNA-LAMP plasmid vaccine by intradermal injection using the Biojector 2000 devibe.

OTHER

Saline Control

The subjects in Cohort 1 will receive four doses of saline control 14 days apart, beginning Day 0. Each dose will be delivered as four separate injections of 0.200 mL volumes administered Intradermally (ID) using the needless Biojector 2000 device in separate skin sites. The use of the four 0.200 mL volumes is necessitated in order to compare the skin test sites to the number of sites in Cohorts 2 (4 sites per dose) and Cohort 3 (2 sites per dose). The multiple intradermal administration sites per dose are because of the dilute vaccine material (2.7 mg/mL).
