Single-ascending-dose Study of the Safety and Immunogenicity of NasoVAX
Single-ascending-dose Study of the Safety and Immunogenicity of NasoVAX
This is a Phase 2a, randomized, double-blind, placebo-controlled trial to evaluate the safety
 and immunogenicity of NasoVAX in healthy adults 18 to 49 years of age. Subjects will be
 screened within 28 days of randomization (Day 1).
This is a Phase 2a, randomized, double-blind, placebo-controlled trial to evaluate the safety
 and immunogenicity of NasoVAX in healthy adults 18 to 49 years of age. Subjects will be
 screened within 28 days of randomization (Day 1). Approximately 60 subjects who meet all
 inclusion and no exclusion criteria and provide written informed consent will be enrolled
 into 3 sequential cohorts of 20 subjects each defined by the viral particle dose (1×10(9th),
 1×10(10th), and 1×10(11th) vp). Within each cohort and its sentinel group, subjects will be
 randomized in a 3:1 ratio to receive 1 intranasal dose of NasoVAX or placebo (Day 1). A
 sentinel group of 5 subjects from each cohort will be dosed and followed through Day 8.
 Dosing of the remainder of each cohort may proceed if no events meeting stopping criteria
 have occurred. The SRC, consisting of the Investigator, the Medical Monitor, and a Sponsor
 Representative, will review AE, reactogenicity, and laboratory data through Day 8 for all
 subjects in each cohort before subjects are randomized to the next higher dose. If any event
 meeting stopping criteria occur, the SRC will review all available safety information before
 additional patients are dosed.
Subjects who meet all of the following criteria may be included in the study:

 1. Men and women 18 to 49 years of age, inclusive

 2. Good general health status as determined by the Investigator

 3. Adequate venous access for repeated phlebotomies

 4. Screening laboratory results within institutional normal range or Grade 1 elevation if
 the Investigator documents clinical insignificance. Creatine kinase or bilirubin may
 be Grade 2 if associated with normal alanine aminotransferase (ALT) and aspartate
 aminotransferase (AST) and the Investigator considers the result not to be clinically
 significant due to vigorous exercise or Gilbert's syndrome

 5. Negative drug and alcohol screen at Screening and predose on Day 1

 6. For women who have not been surgically sterilized or have laboratory confirmation of
 postmenopausal status, negative pregnancy test

 7. Willingness to practice a highly effective method of contraception that may include,
 but is not limited to, abstinence, sex only with persons of the same sex, monogamous
 relationship with a postmenopausal partner, monogamous relationship with vasectomized
 partner, vasectomy, surgical sterilization (hysterectomy, or bilateral tubal ligation,
 salpingectomy, or oophorectomy), licensed hormonal methods, intrauterine device (IUD),
 or consistent use of a barrier method (eg, condom, diaphragm) with spermicide for 28
 days after the NasoVAX/placebo dose

 8. Willingness to participate and comply with all aspects of the study through the entire
 study period, including nasopharyngeal swabs and blood and urine samples

 9. Provision of written informed consent

 Subjects who meet any of the following criteria will be excluded from the study:

 1. Pregnant, possibly pregnant, or lactating women

 2. Household contacts of pregnant women, children < 5 years of age, or immunocompromised
 individuals for the period up through 2 weeks postvaccination

 3. Persons who care for pregnant women, children < 5 years of age, or immunocompromised
 individuals for the period up through 2 weeks postvaccination

 4. Body mass index > 35.0 kg/m2

 5. Positive results for HIV, hepatitis B virus, or hepatitis C virus at Screening

 6. Asthma or other chronic lung disease that is greater than mild in severity.
 Specifically excluded are participants with the any of the following events in the
 past year:

 -  Daily symptoms

 -  Daily use of short acting beta 2 agonists

 -  Use of inhaled steroids or theophylline

 -  Use of pulse systemic steroids

 -  Emergency care or hospitalization related to asthma or other chronic lung disease

 -  Systemic steroids for asthma exacerbation

 7. History of diabetes mellitus (gestational diabetes is allowed if treatment was not
 required postpartum and serum glucose is currently in the normal range)

 8. History of coronary artery disease, arrhythmia, or congestive heart failure

 9. Clinically significant ECG abnormality as determined by the Investigator

 10. Poorly controlled hypertension (systolic blood pressure > 150 mmHg or diastolic blood
 pressure > 95 mmHg) at Screening or predose on Day 1

 11. History of anaphylaxis or angioedema

 12. Known allergy to any of the ingredients in the vaccine formulation

 13. History of chronic rhinitis, nasal septal defect, cleft palate, nasal polyps, or other
 nasal abnormality that might affect vaccine administration

 14. Previous nasal surgery or nasal cauterization

 15. Any symptoms of upper respiratory infection or temperature > 38°C within 3 days before
 Day 1

 16. Any symptoms within 24 hours before Day 1 of upper respiratory illness of allergy
 flare-up that, in the opinion of the Investigator, presents as nasal congestion or
 rhinorrhea that could inhibit the proper administration of the IP

 17. Known or suspected malignancy, excluding non-melanoma skin cancers and other early
 stage surgically excised malignancies that the Investigator considers to be
 exceedingly unlikely to recur

 18. Immunocompromised individuals, including those who have used corticosteroids
 (including intranasal steroids), alkylating drugs, antimetabolites, radiation,
 immune-modulating biologics, or other immunomodulating therapies within 90 days before
 Day 1 or those who plan use during the study period

 19. Use of statin medication within 30 days before Day 1 (see list in Section 6.8.1)

 20. Receipt of intranasal medications (including over-the-counter medications) within 30
 days before Day 1

 21. Receipt of any investigational product (IP) within 30 days before Day 1

 22. Receipt of any vaccine within 30 days before Day 1

 23. Receipt of intranasal vaccine within 90 days before Day 1

 24. Receipt of any influenza vaccine within 6 months before Day 1

 25. Any change in medication for a chronic medical condition within 30 days before Day 1

 26. Past regular use or current use of intranasal illicit drugs

 27. Smoking of any type (eg, cigarettes, electronic cigarettes, marijuana) or use of any
 tobacco product within 30 days before Day 1

 28. Any medical, psychiatric, or social condition or occupational or other responsibility
 that in the judgment of the Investigator would interfere with or serve as a
 contraindication to protocol adherence, assessment of safety (including
 reactogenicity), or a subject's ability to give informed consent
