Efficacy and Immunogenicity of Norovirus GI.1/GII.4 Bivalent Virus-like Particle Vaccine in Adults
Phase 2b, Double-Blind, Randomized, Placebo-Controlled Trial to Evaluate the Efficacy and Immunogenicity of the Intramuscular Norovirus GI.1/GII.4 Bivalent Virus-like Particle Vaccine in Healthy Adults Aged 18 - 49 Years

Detailed Description
The vaccine being tested in this study is called NoV GI.1/GII.4 bivalent VLP vaccine adjuvanted with aluminum hydroxide. The norovirus vaccine is being tested to prevent AGE due to genotype-specific (GI.1 and GII.4) norovirus strains in healthy participants recruited from a US military training installation. This study will look at the illness rate of AGE occurring > 7 days after dosing due to genotype-specific (GI.1 or GII.4) NoV strains represented in the vaccine.
The study will enroll between 2800 and 8700 patients. Participants will be randomly assigned (by chance, like flipping a coin) to one of the two treatment groups-which will remain undisclosed to the participant and study doctor during the study (unless there is an urgent medical need):
- Norovirus GI.1/GII.4 Bivalent VLP Vaccine
- Placebo (dummy inactive solution) - this is a liquid that looks similar to the study drug but has no active ingredient
All participants will receive one dose of study medication on Day 1 administered via intramuscular injection.
This multi-center trial will be conducted in the United States at select military locations. The overall time to participate in this study is up to 45 days for participants in the navy 53 days for participants in the Air Force, and 72 days for participants in the marines. Participants will make multiple visits to the clinic, including a final visit on the last day of study participation (Day 45, 53 or 72) for a follow-up assessment.

- Has a history of body temperature of 38.0°C (100.4°F) or higher within 3 days of intended trial vaccination.
- Has received blood, blood products, and/or plasma derivatives or any parenteral immunoglobulin antibody preparation in the past 3 months.
- Immunosuppressive therapy within 3 months or systemic (e.g., oral or parenteral) corticosteroid treatment within 60 days prior to investigational trial dose administration.
- Is participating in any clinical trial with another investigational product 30 days prior to the first trial visit or intending to participate in another clinical trial at any time during the conduct of this trial.

- Has received any other vaccines within 14 days (for inactivated vaccines) or 28 days (for live vaccines) prior to enrollment in this trial with the exception of routine immunizations as per Military Procedures.
If female of childbearing potential, sexually active, and has not used any of the "acceptable contraceptive methods" for at least 2 months prior to trial entry:
- Of childbearing potential is defined as status post onset of menarche and not meeting any of the following conditions: menopausal for at least 2 years, status after bilateral tubal ligation for at least 1 year, status after bilateral oophorectomy, or status after hysterectomy.
Acceptable birth control methods are defined as one or more of the following:

- Barrier (condom with spermicide or diaphragm with spermicide) each and every time during intercourse.
- Intrauterine device (IUD).
- Monogamous relationship with vasectomized partner. Partner must have been vasectomized for at least six months prior to the participants' trial entry.
- If female of childbearing potential and sexually active, refusal to use an "acceptable contraceptive method" from Day 1 through 6 months after the last dose of trial vaccine. In addition, they must be advised not to donate ova during this period.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of Participants With Moderate or Severe Acute Gastroenteritis (AGE) Occurring for >7 Days After Dosing Due to GI.1 or GII.4 Norovirus Strains (Excluding Co-infection)
Time Frame: Up to Day 47
|
Acute gastroenteritis (AGE) is a sudden inflammation or swelling in the lining of the stomach causing diarrhea and vomiting.
A norovirus AGE case was defined as meeting the work-up definition plus a norovirus positive stool sample or vomitus sample confirmed by reverse transcriptase polymerase chain reaction (RT-PCR).
The severity of AGE was graded by the investigator as per CTCAE criteria.
AGE occurring due to NoV strains excluding co-infection with Salmonella, Shigella or Campylobacter is reported.
The Norovirus strains included: GI.1, GI.7a, GII.2 and GII.4.

Up to Day 47
