  • Adult

Who may be able to join

  • Subjects that participated in the previous Phase I A study who demonstrated a change from positive to Japanese Red Cedar pollen/Mountain Cedar at Day 0, to negative in at Day 132 (to be assigned to Group 1) and who have not experienced a grade 3 adverse reaction.
  • Subjects that participated in the previous Phase I A study who originally tested negative and remained negative to Japanese Red Cedar pollen/Mountain Cedar negative from Day 0 through Day 132 (to be assigned to Group 2 ) and who have not experienced a grade 3 adverse reaction.

  • Female subjects of childbearing potential, defined as not surgically sterile or at least 2 years postmenopausal, must agree to use one of the following forms of contraception for the duration of the study: hormonal (oral, implant, or injection) begun >30 days prior to screening, barrier (condom, diaphragm with spermicide), intrauterine device (IUD), or vasectomized partner (6 months minimum).
  • No clinically significant abnormal findings on the physical examination, with the exception of HEENT (head, eyes, ears, nose and throat) findings consistent with allergic rhinitis, medical history, or clinical laboratory results during screening which, in the opinion of the Investigator, would jeopardize the safety of the subject or impact the validity of the study results.
  • Subject must be willing and able to comply with study requirements.

Who cannot join

  • Previous Japanese red cedar allergen immunotherapy [(Subcutaneous Immunotherapy (SCIT), oral immunotherapy, SLIT(Sublingual Immunotherapy), or recombinant peptide] except for investigational therapy administered in Phase IA (CryJ2-DNA-LAMP) which is not an exclusion criteria.

About this study

Official title: A Safety and Immunogenicity Phase IB Study of CryJ2-DNA-Lysosomal Associated Membrane Protein (CryJ2 -DNA-LAMP) Plasmid Assessing the Long Term Safety of Previously Treated CryJ2-DNA-LAMP Vaccinated Subjects and the Safety of a Booster Vaccination

This is a continuing 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 previous Phase IA research participants respond to the vaccine in a booster dose. 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 IB, prospective, three cohort, open label study conducted on one cohorts of non-atopic subjects and two cohorts of subjects with a history of allergic rhinitis symptoms to Japanese red cedar CryJ 2 pollen allergen that participated in the previous Phase IA study (all the subjects participated in the previous study). The study will be conducted at 1 study center. Subjects are enrolled in the trial for a period of 80 days. The objectives of the statistical analyses are to establish the safety and to explore the immunogenicity of the LAMP-vax vaccine. All statistical analyses conducted on the data from this trial will be exploratory in nature.

The primary objective of this Phase IB Study is to evaluate the safety and immunological responses of an additional dose of CryJ2-DNA-LAMP plasmid vaccine delivered intramuscularly (IM) to subjects who previously received 4 doses of CryJ2-DNA-LAMP vaccine delivered IM every 2 weeks in the previous Phase IA study.

Read the detailed description

A further safety assessment of the JRC sensitive and non-sensitive subjects who were in Group 1, 2 and 3 of the Phase 1A study will be further assessed in terms of current skin test reactivity, re-vaccination safety and continued safety.

Group 1: will receive 2 mg CryJ2-DNA-LAMP plasmid vaccine by intramuscular (IM) injection. The dosing regimen for this group will be to receive one (1) booster dose. This group will be followed for 80 days (+/- 10), assessing skin reactivity and immune response.

Group 2: will receive 2 mg CryJ2-DNA-LAMP plasmid vaccine by intramuscular (IM) injection. The dosing regimen for this group will be to receive one (1) booster dose. This group will be followed for 80 days (+/- 10), assessing skin reactivity and immune response.

Group 3: will receive 2 mg CryJ2-DNA-LAMP plasmid vaccine by intramuscular (IM) injection. The dosing regimen for this group will be to receive one (1) booster dose. This group will be followed for 80 days (+/- 10), assessing skin reactivity and immune response.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of participants with Adverse Events

    The primary objective of this Phase I Study is to evaluate the safety and immunological responses of therapeutic doses and the dosing regimen of CryJ2-DNA-LAMP plasmid vaccine.

    Adverse events will be monitored on each subject from the time of enrollment to exit from the study. Vital signs will be recorded on each subject at baseline and days 50, 80 and early termination. Physical exams will be conducted on the subjects at the baseline and days 50, 80 and early termination.

    Measured: 80 days (+/-)

Secondary outcomes (1)
  1. Immunogenicity and functional variables [Japanese Red Cedar Immunocap (IgE & IgG), Mountain Cedar Immunocap (IgE) & Th1/Th2 cytokines ELISA Panel]

    Immonogenecity parameters include: Japanese Red Cedar Immunocap (IgE \& IgG), Mountain Cedar Immunocap (IgE) \& Th1/Th2 cytokines ELISA Panel.

    These parameters will determine if there is a change in beneficial immunoglobulins(IgG), and changes in Th1/Th2 cytokines in the serum of non-atopic (no allergic sensitivities to CryJ2 allergen) subjects and atopic subjects with known allergy to Japanese Red Cedar CryJ2 allergen. These subjects were identified by positive skin test re-activity and/or IgG specific antibody titers from previous time-points in the Phase IA using one boost of IM route of administration.

    Immunogenicity parameters will be measured at baseline and days 50, 80 or ET of the trial.

    Measured: 80 days (+/-)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing CryJ2-DNA-LAMP plasmid vaccine by intramuscular injection in people with Allergic Rhinoconjunctivitis, run by Immunomic Therapeutics, Inc. at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 18 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 30 Apr 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of participants with Adverse Events (time frame: 80 days (+/-)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Apr 2014.
