Title:
VRC 307: A D/B Randomized Ph. I Study of Safety/Immunogenicity of a Prime-Boost Schedule of an Investigational DNA Influenza Vaccine, Followed by the Seasonal Influenza Trivalent Inactivated Vaccine (TIV), Compared to TIV Alone in Healthy Adults
Number:
09-I-0090
Summary:
This is a Phase I, randomized study in healthy younger (18-50 years) and older (51-70 years) adults. For each age group, the study will evaluate the safety, tolerability, and immunogenicity of a prime-boost vaccination regimen against the seasonal influenza virus with an investigational plasmid DNA vaccine as a prime followed 4 weeks later by the licensed seasonal trivalent influenza vaccine (TIV) boost as compared to the licensed seasonal vaccine alone. Equal numbers of healthy adults in each age group will receive the DNA vaccine as the first injection or a control injection with phosphate buffered saline (PBS) as the first injection. The hypothesis is that the DNA vaccine will be safe for human administration and that the prime-boost schedule will elicit a higher titer antibody response than the licensed seasonal TIV alone. The primary objectives are to evaluate the safety and tolerability and induced antibody titer of the investigational prime-boost regimen, at a dose of 4 mg for the DNA vaccine and 45 micrograms (µ (Micro)g) for the seasonal TIV vaccine. Secondary and exploratory objectives are related to the humoral and cellular immune responses.

Eligibility Criteria:
INCLUSION CRITERIA:

A subject must meet all of the following criteria:

1. 18 to 70 years old.

2. Available for clinical follow-up through Week 24.

3. Able to provide proof of identity to the satisfaction of the study clinician completing the enrollment process.

4. Complete an AoU prior to enrollment and verbalize understanding of all questions answered incorrectly.

5. Able and willing to complete the informed consent process.

6. Willing to donate blood for sample storage to be used for future research.

7. No evidence of previously undiagnosed clinically significant chronic diseases.

8. Physical examination and laboratory results without clinically significant findings and a Body Mass Index (BMI) greater than or equal to 18.5 and less than 40 within the 28 days prior to enrollment.

Laboratory Criteria within 28 days prior to enrollment:

9. Hemoglobin greater than or equal to 11.5 g/dL for women; greater than or equal to 13.5 g/dL for men

10. White blood cells (WBC) = 3,300-12,000 cells/mm(3)

11. Differential either within institutional normal range or accompanied by site physician approval as a differential that is consistent with healthy volunteer status

12. Total lymphocyte count greater than or equal to 800 cells/ mm(3)

13. Platelets = 125,000 - 400,000/ mm(3)

14. Alanine aminotransferase (ALT) less than or equal to 2.5 times the upper limit of normal (ULN)

15. Serum creatinine less than or equal to 1 x ULN (less than or equal to 1.3 mg/dL for females; less than or equal to 1.4 mg/dL for males) and estimated glomerular filtration rate greater than 60.

16. Negative FDA-approved HIV blood test. [Note: Results of HIV enzyme-linked immunosorbent assay (ELISA) will be documented, but a negative HIV polymerase chain reaction (PCR) test result will be sufficient for eligibility screening of subjects with positive HIV ELISA that is due to prior participation in an HIV vaccine study].

Female-Specific Criteria:

17. Negative human chorion gonadotropin (beta-HCG) pregnancy test (urine or serum) for women presumed to be of reproductive potential.

18. A female subject must meet one of the following criteria:

No reproductive potential because of menopause [one year without menses] or because of a hysterectomy, bilateral oophorectomy, or tubal ligation,

OR

Agrees to be heterosexually inactive at least 21 days prior to enrollment and through Week 24 of the study,

OR

Agrees to consistently practice contraception at least 21 days prior to enrollment and through Week 24 of the study by one of the following methods:

-condoms, male or female, with or without a spermicide;

-diaphragm or cervical cap with spermicide;

-intrauterine device;

-contraceptive pills, patch, implant or any other FDA-approved contraceptive method;

-male partner has previously undergone a vasectomy.

EXCLUSION CRITERIA:

A subject will be excluded if one or more of the following conditions apply.

Women Specific:

1. Breast-feeding or planning to become pregnant during the first 28 weeks after enrollment in the study.

Subject has received any of the following substances:

2. Immunosuppressive medications, cytotoxic medications, inhaled corticosteroids, or long-acting beta-agonists within the 12 weeks prior to enrollment. [With the exceptions that use of corticosteroid nasal spray for rhinitis; topical corticosteroids for an acute uncomplicated dermatitis; or short-acting beta-agonists in controlled asthmatics; or a short course (duration of 10 days or less or a single injection) of corticosteroids for a non-chronic condition at least 2 weeks prior to enrollment in this study will not exclude study participation.]

3. Immunized with a current season FDA-approved influenza vaccine prior to enrollment.

4. Influenza infection within 6 months prior to enrollment (as assessed by clinician review of subject's self-report of a clinical course consistent with influenza).

5. Blood products within 120 days prior to HIV screening

6. Immunoglobulin within 60 days prior to HIV screening

7. Live attenuated vaccines within 30 days prior to initial study vaccine administration

8. Investigational research agents within 30 days prior to initial study vaccine administration

9. Medically indicated subunit or killed vaccines (e.g., pneumococcal, or allergy treatment with antigen injections) within 14 days of initial study vaccine administration

10. Current anti-TB prophylaxis or therapy

Subject has a history of any of the following clinically significant conditions:

11. Autoimmune disease or immunodeficiency.

12. Contraindication to receiving an FDA approved current seasonal influenza vaccination (e.g., egg allergy).

13. Serious adverse reactions to vaccines such as anaphylaxis, urticaria (hives), respiratory difficulty, angioedema, or abdominal pain.

14. Hereditary angioedema (HAE), acquired angioedema (AAE), or idiopathic forms of angioedema.

15. Asthma that is unstable or required emergent care, urgent care, hospitalization or intubation during the past two years or that requires the use of oral or intravenous corticosteroids.

16. Diabetes mellitus (type I or II), with the exception of gestational diabetes.

17. Thyroidectomy or thyroid disease that required medication within the past 12 months.

18. Idiopathic urticaria within the past 2 years

19. Hypertension that is not well controlled by medication or is more than 145/95 at enrollment.

20. Bleeding disorder diagnosed by a doctor (e.g. factor deficiency, coagulopathy, or platelet disorder requiring special precautions) or significant bruising or bleeding difficulties with IM injections or blood draws.

21. Malignancy that is active or treated malignancy for which there is not reasonable assurance of sustained cure or malignancy that is likely to recur during the period of the study.

22. Seizure disorder other than: 1) febrile seizures under the age of two, 2) seizures secondary to alcohol withdrawal more than 3 years ago, or 3) a singular seizure not requiring treatment within the last 3 years.
