Study of BPZE1 Intranasal Pertussis Vaccine (Administered Via VaxINator(TM)), Prime + Boost, in Healthy Adults
Phase 2b Study of BPZE1 Intranasal Pertussis Vaccine in Adults to Assess Immunological Response and Safety Profile of 1-Dose (Prime) and 2-Doses (Prime+Boost) Schedule, Compared to a Boostrix™ Prime Dose With or Without a BPZE1 Boost Dose
Lead SponsorILiAD Biotechnologies
StatusCompleted No Results Posted
Indication/ConditionPertussis Whooping Cough
Intervention/TreatmentBPZE1 pertussis vaccine and VaxINator(TM) Atomization Device
This study evaluates the safety and immunogenicity of the BPZE1 live attenuated pertussis vaccine, intended to prevent nasopharyngeal colonization and pertussis disease, and compares a single (prime) BPZE1 dose or 2-dose (prime + boost) to a single (prime) Boostrix or BPZE1 prime + Boostrix boost. This is a multi-center, randomized, placebo-controlled, and observer blinded trial in healthy adults with a 6 month safety follow-up after the last vaccination.

Inclusion Criteria: Is a male or nonpregnant female 18 to 50 years of age, inclusive, on Day 1 (primary vaccination). Is capable of understanding the written informed consent, provides signed and witnessed written informed consent, and agrees to comply with protocol requirements. Female subjects must be nonpregnant and nonlactating and meet 1 of the following criteria: Postmenopausal (defined as 12 consecutive months with no menses without an alternative medical cause or documented plasma follicle-stimulating hormone level in the postmenopausal range); Surgically sterile (ie, hysterectomy, bilateral tubal ligation, or bilateral oophorectomy). NOTE: These procedures and laboratory test results must be confirmed by physical examination, or by subject recall of specific date and hospital/facility of procedure, or by medical documentation of said procedure. Is of childbearing potential (defined as any female who has experienced menarche and who is NOT permanently sterile or postmenopausal), agrees to be heterosexually inactive from at least 21 days prior to enrollment and through 3 months after the boosting vaccination or agrees to consistently use any of the following methods of contraception from at least 21 days prior to enrollment and through 3 months after the boosting vaccination: i. Condoms (male or female) with spermicide ii. Diaphragm with spermicide iii. Cervical cap with spermicide iv. Intrauterine device v. Oral or patch contraceptives vi. Norplant®, Depo-Provera®, or other FDA approved contraceptive method that is designed to protect against pregnancy. NOTE: Periodic abstinence (eg, calendar, ovulation, symptothermal, post ovulation methods) and withdrawal are not acceptable methods of contraception. Has a stable health status as assessed by the investigator, as established by physical examination, vital sign measurements, and medical history. Has access to a consistent and reliable means of telephone contact, which may be in the home, workplace, or by personal mobile electronic device. Is able to understand and comply with planned study procedures. Lives a reasonable distance from the clinical site to be able to travel to and from the clinical site for follow-up visits and agrees to go to the clinical site for evaluation (or provide medical record access if evaluated elsewhere) in the event of an AE. Agrees to stay in contact with the clinical site for the duration of the study, has no current plans to move from the study area, and provides updated contact information as necessary. Exclusion Criteria: History of being vaccinated in the past 5 years against pertussis. Any significant past reaction to any component of Boostrix (at the discretion of the investigator). Subject reported diagnosis of pertussis in the past 10 years (must be laboratory confirmed or physician diagnosed from medical records). Vital signs by FDA toxicity scoring >1 (may be repeated once during the screening period to allow for inclusion and the most recent measurement taken at baseline). Chronic illness being treated actively and with evidence of recent intervention for worsening or fluctuating symptoms (at the discretion of the investigator). The subject has a history of active cancer (malignancy) in the last 10 years (exception is subjects with adequately treated non melanomatous skin carcinoma, who may participate in the study). Current use of any smoking products and unwillingness to refrain from the use of any smoking products from screening through 28 days after the boosting vaccination. Use of narcotic drugs, evidenced by urine toxicology screen or a history of drug/alcohol abuse within the past 2 years. Has donated blood or suffered from blood loss of more than 450 mL (1 unit of blood) within 60 days prior to screening or donated plasma within 14 days prior to screening. Receipt of immunoglobulin, blood-derived products, systemic corticosteroids, or other immunosuppressant drugs within 90 days prior to Day 1. Asthma, obstructive nasal canal, recurrent or acute sinusitis or other chronic respiratory problems inclusive of the diagnosis of any significant pulmonary disease. History of nasal surgery or Bell's palsy. Use of repeated nasal sprays, Neti pot, routine nasal washing within the past 1 month (more than 2 times per week). Subjects must agree to refrain from use of any of these modalities through Day 113. A temporary exclusion to vaccinate if acute respiratory tract infection or rhinorrhea or temperature >100.4°F (no symptoms for 3 days prior to vaccination day). Subjects may be vaccinated if they stay within the vaccination window (screening [30 days] or at the time of the booster [10 days]). NOTE: If a subject exceeds the screening window, they must be reconsented and screening must be reinitiated. Use of corticosteroids in the respiratory tract (eg, nasal steroids, inhaled steroids) within 30 days prior to Day 1. Receipt of a licensed vaccine within the last 30 days prior to Day 1 or planned vaccination during the active study conduct through Day 113. In the case of seasonal influenza, vaccination should not be withheld and is not contraindicated for subject participation. However, vaccination should be planned outside of a 30 day pre- and 30 day post vaccination window whenever possible. Known hypersensitivity to any component of the study vaccines. Participation in any other clinical trial for the testing of an unlicensed product during the previous 6 months or planned during the study conduct. Inability to adhere to the protocol, including plans to move from the area. Personal history or family (first degree) history of congenital or hereditary immunodeficiency.
