H5-VLP + GLA-AF Vaccine Trial in Healthy Adult Volunteers

A Phase 1, Randomized Clinical Trial to Evaluate the Safety, Tolerability, and Immunogenicity of the H5-VLP + GLA-AF Pandemic Influenza Vaccine in Healthy Adult Subjects

NCT01657929•Access to Advanced Health Institute (AAHI)

View on ClinicalTrials.gov

Summary

The purpose of this study is to determine the safety, tolerability, and immunogenicity in healthy adult subjects of an investigational vaccine being developed for the prevention of pandemic influenza. The vaccine, identified as H5-VLP + GLA-AF, consists of a recombinant influenza virus H5 protein (hemagglutinin from A/Indonesia/5/2005) produced in a plant-based expression system assembling into virus-like particles together with the adjuvant GLA-AF.

Inclusion Criteria

•Males and females 18 to 49 years of age.
•Must be in good general health as confirmed by a medical history and physical exam, vital signs, and screening laboratories conducted no more than 30 days prior to study injection administration.
•Female subjects of childbearing potential, regardless of birth control history, must have a negative serum pregnancy test at screening, a negative urine pregnancy test on the day of each study injection, must not be breast-feeding or lactating, and are required to consistently use one of the following methods of contraception through the first three months of the study: hormonal (e.g. oral, transdermal, intravaginal, implant, or injection); double barrier (i.e., condom, diaphragm with spermicide); intrauterine device (IUD) or system (IUS); vasectomized partner (6 months minimum); abstinence (as confirmed by the investigator); or bilateral tubal ligation (if no conception post-procedure). These precautions are necessary due to unknown effects that H5-VLP + GLA AF or H5-VLP alone might have in a fetus or newborn infant. The subject must have no plan to become pregnant during the first three months of the study period. Females who are post-menopausal (no spotting at all) for at least one (1) year will not require a pregnancy test.
•The following screening laboratory blood tests must have values within the normal ranges (as provided by each clinical site) or not clinically significant as determined by the Principal Investigator (or designated sub-investigator) and Medical Monitor (all test results must be within 30 days prior to first study injection): sodium, potassium, BUN, ALT, AST, total bilirubin, alkaline phosphatase, creatinine, fasting glucose, fasting lipid panel, total WBC count, hemoglobin, and platelet count.
•The following serology tests must be negative: HIV 1/2 antibody, hepatitis B surface antigen (HBsAg), and hepatitis C virus (HCV) antibody.
•Negative urine test for recreational drugs and alcohol per Clinical Research Unit standards.
•Urinalysis not clinically significant as determined by the study clinician.
•In the opinion of the Investigator, must show comprehension of the study requirements, competence and willingness to provide written, informed consent for participation after reading the informed consent form. The subject must have adequate opportunity to discuss the study with an Investigator or qualified designee.
•Must be capable of completing a study memory aid in English.
•Must be able and willing to attend all evaluation visits, be reachable by telephone on a consistent basis by the study site personnel, and have a permanent address.

Exclusion Criteria

•Previous exposure to H5N1 vaccines or experimental products containing GLA-AF.
•History of allergy to any of the constituents of H5-VLP (H5N1) + Alhydrogel (aluminum hydroxide) vaccine.
•Participation in another experimental protocol or receipt of any investigational or non-registered products within the past 3 months or planned use during the study period. Subjects may not participate in any other drug study while participating in this study.
•Treatment with immunosuppressive drugs (e.g., oral or injected steroids, such as prednisone; high dose inhaled steroids) or cytotoxic therapies (e.g., chemotherapy drugs or radiation) within the past 6 months.
•Received a blood transfusion or immunoglobulin within the past 3 months.
•Donated blood products (platelets, whole blood, plasma, etc.) within past 1 month.
•Poor venous access.
•Administration of any vaccine (including any other influenza vaccine) within a 30 day period prior to study enrollment, or planned administration of any vaccines within the period from the first study injection up to blood sampling at Day 42 or within 30 days prior to blood sampling at Day 189. Immunization on an emergency basis of a tetanus and diphtheria toxoids adsorbed for adult use (Td) will be allowed provided the vaccine is not administered within two weeks prior to study injection administration. Receipt of any other emergency immunizations (e.g. rabies) will result in a case-by-case review of continued participation.
•History of autoimmune disease or other causes of immunosuppressive states.
•Any confirmed or suspected immunosuppressive condition or immunodeficiency including history of human immunodeficiency virus (HIV) infection or presence of lymphoproliferative disease.
