Brief Summary:
This Phase 1 trial is an open-label trial to evaluate the safety, tolerability and immunogenicity of a single dose (10^7.5 PFU) of intranasal BLB-201 (a recombinant parainfluenza virus type 5) administered as a single dose in 15 healthy young adults ages 18-59 years, and 15 older adults ages 60-75 years.

Condition or disease Intervention/treatment Phase
Respiratory Syncytial Virus Infections Biological: CPI-RSV-F Vaccine (BLB-201) Phase 1

Detailed Description:
This will be an open-label, age-escalation phase 1 trial of the PIV5 virus-vectored BLB-201 vaccine in healthy adults (males and nonpregnant females) 18 to 59 years of age (Group 1), and 60 to 75 years of age (Group 2). The trial is designed to assess the safety, tolerability, and immunogenicity of a single dose of intranasal BLB-201 at 10^7.5 plaque- forming units (PFU) in both Group 1 and Group 2. The first 4 subjects in each group will be enrolled as sentinels and vaccination will proceed in a staged fashion.

Primary Outcome Measures :
  1. Solicited Adverse Events [ Time Frame: Day 1-8 ]
    Frequencies and grades of solicited local and systemic AEs during a 7-day period after dosing.

  2. Unsolicited Adverse Events [ Time Frame: Day 1-29 ]
    Frequencies and grades of unsolicited AEs during a 28-day period after dosing.


Secondary Outcome Measures :
  1. Serum IgG titers to RSV protein [ Time Frame: Day 15, and Day 29 ]
    Change in RSV specific IgG titers after the first dose of BLB-201

  2. Serious Adverse Events through trial completion [ Time Frame: Day 1-181 ]
    Frequencies of Serious Adverse Events (SAEs) categorized by vaccine relatedness from the first dose of BLB-201 through trial completion (approximately 6 months after dosing).

  3. Serious adverse events, new-onset chronic medical conditions, and adverse events of special interest [ Time Frame: Day 1-181 ]
    Frequencies of Serious Adverse Events (SAEs) categorized by vaccine relatedness, new-onset chronic medical conditions (NOCMCs), and adverse events of special interest (MAAEs), from the first dose of BLB-201 through trial completion (approximately 6 months after dosing).

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes
Criteria

Inclusion Criteria:

  • Provide informed consent prior to initiation of any trial procedures.
  • Be able to understand and agrees to comply with planned trial procedures and be available for all trial visits and phone calls.

  • Women of childbearing potential must have a negative urine or serum pregnancy test within 24 hours prior to each vaccination.
  • Male subjects of childbearing potential* must use condoms to ensure effective contraception with a female partner of childbearing potential from vaccination until 90 days after vaccination. Such female partners must also use an acceptable form of primary contraception as described under inclusion criterion #4. If barrier methods are to be used, then double barrier methods of protection are required, i.e. male condom, in combination with a cap, diaphragm, or sponge with spermicide. *Biological males who are post-pubertal and considered fertile until permanently sterile by bilateral orchiectomy or vasectomy.
  • Male subjects agree to refrain from sperm donation from the time of vaccination until 90 days after vaccination.
  • Female subjects agree to refrain from egg donation from time of vaccination until 90 days after vaccination.
  • In good health.
