Clinical Trial Summary

The purpose of this study is to collect serum samples to evaluate serologic assays and to establish proficiency panels for serologic assays used for assessment of post vaccination immune response after intramuscular (IM) vaccination with Norovirus GI.1/GII.4 bivalent virus-like particle (VLP) vaccine.

Description:

The vaccine being tested in this study is called Norovirus GI.1/GII.4 bivalent Virus-Like Particle Vaccine (NoV Vaccine). The purpose of this study is to collect serum samples to evaluate serologic assays and to establish proficiency panels for serologic assays used for assessment of post vaccination immune response after intramuscular (IM) vaccination with the NoV vaccine. The validation and proficiency testing of the immunogenicity assays is required to support the NoV Vaccine development program. This study also looked at side effects in people who were administered a single dose of the NoV vaccine.

The study enrolled 50 patients. All participants received one dose of the NoV vaccine via intramuscular injection.

Participants were asked to record any symptoms that may be related to the vaccine or the injection site in a diary card for 7 days after receiving the vaccination.

This single-centre trial was conducted in the United States. The overall time to participate in this study was 183 days. Participants made 4 visits to the clinic, and were contacted by telephone 183 days after last dose of study drug for a follow-up assessment.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants With Serum Samples Obtained on Day 8 for Assessment of Seropositivity for Both Anti-NoV GI.1 VLP and GII.4 VLP Antibodies	Serum samples were obtained for assay validation of the pan-Ig enzyme-linked immuno-sorbent assay (ELISA) and the histoblood group antigen (HBGA) binding assay. The number of participants with assessments for both the GI.1 VLP and GII.4 VLP antibodies and by both the pan-Ig ELISA and the HBGA binding assay, and with values available at Baseline and Day 8 are reported.	Day 8
Primary	Number of Participants With Serum Samples Obtained on Day 15 for Assessment of Seropositivity for Both Anti-NoV GI.1 VLP and GII.4 VLP Antibodies	Serum samples were obtained to establish proficiency panels for the pan-Ig ELISA and the HBGA binding assay. The number of participants with assessments for both the GI.1 VLP and GII.4 VLP antibodies and by both the pan-Ig ELISA and the HBGA binding assay, and with values available at Baseline and Day 15 are reported.	Day 15
Primary	Number of Participants With Serum Samples Obtained on Day 29 for Assessment of Seropositivity for Both Anti-NoV GI.1 VLP and GII.4 VLP Antibodies	Serum samples were obtained to establish proficiency panels for the pan-Ig ELISA and the HBGA binding assay.

Day 29
Secondary	Percentage of Participants With Solicited Local (Injection Site) Adverse Events (AEs) by Maximum Severity	Safety assessment included collection of solicited local AEs for 7 days following vaccination (including the day of vaccination) by using diary cards. Solicited local injection site AEs are defined as pain, erythema (redness), induration and swelling. Pain is summarized as either none or any, where 'any' will be broken down into the following severity categories: mild, moderate, severe. Erythema, swelling and induration are recorded as yes or no, where the definition of 'yes' is any area =2.5 cm; and 'yes' is further broken down into the following severity categories: =2.5 cm - =5.0 cm (mild intensity), >5.0 cm - = 10.0 cm (moderate intensity), >10.0 cm severe intensity). Injection site AEs are presented as the percentage of participants experiencing a reaction, by reaction type, overall and by severity, using the participant's worst reported severity grade. Only categories for which there was at least 1 participant are reported.	Days 1 through 7
Secondary	Percentage of Participants With Solicited Systemic Adverse Events (AEs) by Maximum Severity	Safety assessment included collection of solicited systemic AEs for 7 days following vaccination (including the day of vaccination) by using diary cards. Solicited systemic AEs are defined as headache, fatigue, myalgia, arthralgia, vomiting and diarrhea and are summarized as either none or any, where 'any' will be broken down into the following severity categories: mild, moderate, severe. Solicited systemic AEs are presented as the percentage of participants experiencing a solicited systemic AE, by AE, overall and by severity, using the participant's worst reported severity grade. Only categories for which there was at least 1 participant are reported.	Days 1 through 7
Secondary	Percentage of Participants With Elevated Daily Oral Temperature	Safety assessment included measurement of body temperature for 7 days following vaccination (including the day of vaccination) by using diary cards. Participants recorded the highest body temperature observed each day in a daily diary. The highest body temperature measurement per participant across Day 1 to Day 7 was categorized as fever present (=100.4ºF, =38ºC) or fever absent (<100.4ºF, <38ºC).	Days 1 to 7 days after vaccination
Secondary	Percentage of Participants With Unsolicited Adverse Events (AEs) by Maximum Severity	An AE is defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. Unsolicited AEs are any AEs that are not solicited local or systemic AEs, as defined by this study. Unsolicited AEs are presented as the percentage of participants experiencing at least one AE, overall and by severity, using the participant's worst reported severity grade. Only categories for which there was at least 1 participant are reported.	Days 1 through 28
Secondary	Percentage of Participants Experiencing Serious Adverse Events	A serious adverse event (SAE) is any untoward medical occurrence or effect that at any dose results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability / incapacity, is a congenital anomaly / birth defect or is medically important due to other reasons than the above mentioned criteria.	Day 1 up to Day 183
