Brief summary

The purpose of this study is to further develop a formulation and dose regimen of the norovirus GI.1/GII.4 bivalent virus-like particle (VLP) vaccine that is immunogenic and safe in an elderly population aged 60 years and above.

Detailed description

The vaccine being tested in this study is called norovirus GI.1/GII.4 bivalent virus-like particle (VLP) vaccine adjuvanted with aluminum hydroxide (Formulation A) or adjuvanted with monophosphoryl lipid A (MPL) and aluminum hydroxide (Formulation B). Two norovirus vaccine formulations are being tested to select for further development the formulation that will generate an optimal specific antibody response that may provide protection against norovirus and is safe in a population aged 60 years and above. This study will look at side effects and the level of antibodies to norovirus formed in people who will be injected with different formulations of the norovirus vaccine candidate. The study will enroll approximately 325 patients. Participants will be randomly assigned (by chance) to one of five treatment groups. * Norovirus GI.1/GII.4 bivalent VLP vaccine (Formulation A) 1-dose, participants ≥ 60 years * Norovirus GI.1/GII.4 bivalent VLP vaccine (Formulation A) 2-dose, participants ≥ 60 years * Norovirus GI.1/GII.4 bivalent VLP vaccine (Formulation B) 1-dose, participants ≥ 60 years * Norovirus GI.1/GII.4 bivalent VLP vaccine (Formulation B) 2-dose, participants ≥ 60 years * Norovirus GI.1/GII.4 bivalent VLP vaccine (Formulation A) 1-dose, participants 18 to 49 years All participants in the age of 60 years and older will be administered either NoV vaccine (Formulation A or B) or placebo on Day 1 and NoV vaccine (Formulation A or B) on Day 29 of the study. In order to keep the treatment arms undisclosed to the patient and the doctor, those randomized to the one dose groups will receive a dose of placebo (this is a saline solution that has no active ingredient) on Day 1 followed by the NoV vaccine on Day 29. Those randomized to 2 doses with receive the NoV vaccine on Day 1 and Day 29. In case of an urgent medical need a participant can be unblinded. Adults aged 18 to 49 will receive placebo on Day 1 followed by NoV vaccine Formulation A on Day 29. Participants will be asked to record any reactions/ symptoms that may be related or not to the vaccine in a diary card for 28 days after each vaccination. This multi-center trial will be conducted in the United States of America. The overall time to participate in this study is up to 393 days. Participants will make multiple visits to the clinic including a final follow-up visit on Day 393.

Inclusion criteria

1. Is aged 18 to 49 years, or 60 years and older at the time of enrollment; 2. Participants who are in good health, or in stable health status with no exclusionary medical or neuropsychiatric conditions at the time of entry into the trial as determined by medical history, physical examination (including vital signs) and clinical judgment of the Investigator; 3. Participant signs and dates a written, Informed Consent Form (ICF) and any required privacy authorization prior to the initiation of any trial procedures, after the nature of the trial has been explained according to local regulatory requirements; 4. Participants who can comply with trial procedures and are available for the duration of follow-up.

Exclusion criteria

1. Has a known hypersensitivity or allergy to any of the Norovirus (NoV) GI.1/GII.4 Bivalent virus-like particle (VLP) Vaccine components; 2. Has a clinically significant active infection (as assessed by the Investigator) or body temperature ≥38°C/100.4°F within 3 days of the intended date of vaccination; 3. Participants with the presence of significant acute or chronic, uncontrolled medical or neuropsychiatric illness. Uncontrolled was defined as: Requiring institution of new medical or surgical treatment within 3 months prior to immunization, or Requiring a change in medication dosage in the 3 months prior to immunization due to uncontrolled symptoms or drug toxicity (elective dosage adjustments in stable participants were acceptable), or Hospitalization or an event fulfilling the definition of a serious adverse event within 3 months prior immunization. 4. Has any unstable medical or neuropsychiatric condition, which in the Investigator's opinion poses a risk of unusual magnitude for the participant's age group of hospitalization, death, or an event meeting the definition of a serious adverse event within 2 months of immunization. The intent of this criterion is to recognize and allow for the frequent existence of significant health concerns in this population; but exclude those participants who are experiencing an acute decline in health status; 5. Has any medical or neuropsychiatric condition, which in the Investigator's opinion, rendered the participant incompetent to provide informed consent or unable to provide valid safety observations and reports; 6.

Geometric Mean Fold Rise (GMFR) of Anti-norovirus GI.1 VLP Antibody Titers (HBGA)

GMFR of anti-norovirus GI.1 VLP antibody titers measured by HBGA blocking assay are reported. The fold rise was calculated as the ratio of the post-vaccination titer level to the pre-vaccination titer level.

Time frame: Days 8, 29, 36, 57, 211 and 393

Population: PPS included all participants in the FAS, who received the planned vaccination (both doses of vaccine, i.e. NoV VLP vaccine or placebo), and did not have major protocol violations. Number analyzed is the number of participants with evaluable data at the given time point.

Percentage of Participants With At Least One Adverse Event (AE) Leading to Participant's Withdrawal From the Study

Withdrawal due to an AE will occur if the participant experiences an AE that requires early termination of treatment, because continued participation imposes an unacceptable risk to the participant's health or the participant is unwilling to continue because of the AE.

Time frame: From first vaccination up to Day 393

Population: SAF included all participants who received at least 1 dose of vaccine (NoV VLP vaccine or placebo).
