Study to Evaluate the Safety and Immunogenicity of Poly ICLC (Hiltonol) in Healthy Volunteers

March 27, 2014 updated by: Rockefeller University

A Randomized, Placebo-controlled, Phase I Study to Evaluate the Safety and Immunogenicity of Poly ICLC (Hiltonol) in Healthy Volunteers

Vaccines induce protective immunity against numerous infectious diseases. However, current vaccines have limited efficacy against challenging infections like tuberculosis, malaria and HIV. Protein vaccines are safe but, typically, they induce weak T cell immunity when administered alone. Therefore, special attention is being given to adjuvants, which are enhancers of immunity, that mature antigen presenting immunostimulatory dendritic cells (DCs). Our goal is to study in humans the mechanism whereby synthetic adjuvants, acting on defined pattern recognition receptors (PRR), enhance T and B cell immunity. In preclinical studies, the investigators' laboratory has found in mice that poly IC and its analog poly ICLC are superior adjuvants for T cell mediated immunity relative to other agonists for PRR. In this study the investigators propose to study the safety and the innate immune responses to poly ICLC in multiple blood cell types, including three different subsets of DCs when administered subcutaneously or intranasally to healthy volunteers. Poly ICLC is a stabilized double stranded RNA which has been extensively studied in humans with a favorable safety profile.

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 to 60 years (ADULT)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

    • Be surgically sterile Be abstinent (or willing to be)

  5. Any clinically significant acute or chronic medical conditions requiring care of a physician (e.g., diabetes, coronary artery disease, rheumatologic illness, malignancy, substance abuse) that in the opinion of the investigator would preclude participation
  6. Any laboratory value outside of reference range, with the exception of any non-clinically significant Grade 1 elevations of liver function tests (AST, ALT, direct/total bilirubin), CBC, as determined by the Principal Investigator or her designee
