H5N1 With or Without Topical Aldara in Healthy Adults

Completed · Phase 1

Conditions studied: Avian Influenza, Influenza Immunisation

In brief

Phase I randomized, double-blind, placebo-controlled trial in 50 males and non-pregnant females, 18 to 49 years old, who are in good health and meet all eligibility criteria. This clinical trial is designed to assess the safety, reactogenicity, and immunogenicity of inactivated A/H5N1 influenza vaccine administered intradermally (ID) with topical Aldara or control cream as a 2-dose regimen. The vaccine will be administered using the MicronJet600(TM) device. Subjects will be assigned to 2 treatment arms (25 subjects per treatment arm). Group A will receive two doses of A/H5N1 IIV ID with pre-application of topical Aldara on Days 1 and 22. Group B will receive two doses of A/H5N1 IIV ID with pre-application of topical control cream on Days 1 and 22. The duration of this study will be approximately 20 months with patient participation duration approximately 7 months. The primary objectives of this study are: 1) to assess the safety and reactogenicity after 2 doses of A/H5N1 IIV vaccine containing 9 mcg HA per dose administered ID approximately 21 days apart with topical Aldara or control cream; 2) to assess the serum HAI antibody responses 21 days after receipt of the 2nd dose of A/H5N1 IIV administered ID at 9 mcg HA per dose with topical Aldara or control cream.

Who can join

Age: 18 and older, up to 49. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• Provide written informed consent prior to initiation of any study procedures.
• Are able to understand and comply with planned study procedures and be available for all study visits.
• Are males or non-pregnant females, 18 to 49 years old, inclusive.
• Are in good health, as determined by vital signs (oral temperature, pulse, and blood pressure), medical history, and physical examination to ensure any existing medical diagnoses or conditions (except those exclusionary) are stable.
• Stable chronic medical condition - no change in prescription medication, dose, or frequency of medication in the last 2 months (defined as 60 days) and health outcomes of the specific disease are considered to be within acceptable limits in the last 6 months (defined as 180 days). Any change that is due to change of health care provider, insurance company etc., or that is done for financial reasons, as long as in the same class of medication, will not be considered a violation of this inclusion criterion. Any change in prescription medication due to improvement of a disease outcome, as determined by the site principal investigator or appropriate sub-investigator, will not be considered a violation of this inclusion criterion.
• - Subjects may be on chronic or as needed (prn) medications if, in the opinion of the site principal investigator or appropriate sub-investigator, they pose no additional risk to subject safety or assessment of reactogenicity and immunogenicity. Note: Topical, nasal, and inhaled medications (with the exception of steroids as outlined in the Subject Exclusion Criteria), vitamins, and contraceptives are permitted.
• Oral temperature is less than 100.0 degrees F.
• Pulse is 47 to 100 bpm, inclusive.
• Systolic blood pressure is 85 to 150 mm Hg, inclusive.
• Diastolic blood pressure is 55 to 95 mmHg, inclusive.
• Women of childbearing potential must use an acceptable method of contraception from 30 days prior to vaccination until 60 days after the last study vaccination.
• Not sterilized via tubal ligation, bilateral oophorectomy, hysterectomy, or successful Essure(R) placement (permanent, non-surgical, non-hormonal sterilization) with documented radiological confirmation test at least 90 days after the procedure, and still menstruating or < 1 year of the last menses if menopausal).
• - Includes non-male sexual relationships, abstinence from sexual intercourse with a male partner, monogamous relationship with a vasectomized partner, male condoms with the use of applied spermicide, intrauterine devices, NuvaRing(R), and licensed hormonal methods such as implants, injectables or oral contraceptives ("the pill"). Method of contraception will be captured on the appropriate data collection form.
• Female subjects of childbearing potential must have a negative urine pregnancy test within 24 hours prior to study vaccination.

You may not qualify if…

• Have an acute illness, as determined by the site PI or appropriate sub-investigator, within 72 hours prior to study vaccination.
• An acute illness which is nearly resolved with only minor residual symptoms remaining is allowable if, in the opinion of the site PI or appropriate sub-investigator, the residual symptoms will not interfere with the ability to assess safety parameters as required by the protocol.
• Have any medical disease or condition that, in the opinion of the site PI or appropriate sub-investigator, is a contraindication to study participation.
• Including acute or chronic medical disease or condition, defined as persisting for at least 90 days, that would place the subject at an unacceptable risk of injury, render the subject unable to meet the requirements of the protocol, or may interfere with the evaluation of responses or the subject's successful completion of this study.
• Have immunosuppression as a result of an underlying illness or treatment, or use of anticancer chemotherapy or radiation therapy (cytotoxic) within 3 years prior to study vaccination.
• Have known active neoplastic disease or a history of any hematologic malignancy. Non-melanoma skin cancers that are not active are permitted.
• Have known HIV, chronic hepatitis B virus, or chronic hepatitis C infection.
• Have known hypersensitivity or allergy to eggs, egg or chicken protein, or other components of the study vaccine.
• Have a history of severe reactions following previous immunization with licensed or unlicensed influenza vaccines.
• Have a history of Guillain-Barré Syndrome.
• Have a history of alcohol or drug abuse within 5 years prior to study vaccination.
• Have any diagnosis, current or past, of schizophrenia, bipolar disease, or other psychiatric diagnosis that may interfere with subject compliance or safety evaluations.
• Have been hospitalized for psychiatric illness, history of suicide attempt, or confinement for danger to self or others within 10 years prior to study vaccination.
• Have taken oral or parenteral (including intraarticular) corticosteroids of any dose within 30 days prior to study vaccination.
• Have taken high-dose dose inhaled corticosteroids within 30 days prior to study vaccination.
• High-dose defined as the dose in mcg/day of an inhaled steroid used alone or in combination with other inhaled medications. Available at: https://www.nhlbi.nih.gov/health-pro/guidelines/current/asthma-guidelines/quick-reference-html#estimated-comparative-daily-doses
• - Topical and nasal steroids are permissible.
• Received any licensed live vaccine within 30 days prior to the first study vaccination.
• Received a licensed inactivated vaccine within 14 days prior to the first study vaccination.
• Plans to receive any licensed vaccine from the time of the first study vaccination through the follow-up visit at approximately 21 days after the last study vaccination.
• Received immunoglobulin or other blood products (with exception of Rho D immunoglobulin) within 90 days prior to study vaccination.
• Received an experimental agent within 30 days prior to the first study vaccination, or expects to receive an experimental agent during study paticipation.
• Including vaccine, drug, biologic, device, blood product, or medication.
