Immunogenicity of QIVc to comparator TIVc (For H1N1, H3N2 and B1 strain, the comparison is between QIVc and TIV1c and for B2 i.e. alternate B strain, the comparison is between QIVc and TIV2c) was assessed in terms of GMT in subjects measured by hemagglutination inhibition (HI) assay, three weeks after vaccination with one dose of either QIVc or TIV1c and TIV2c. Non-inferiority was established if the upper bound of the two-sided 95% confidence interval (CI) for the ratio of GMTs (GMT TIV1c or TIV2c /GMT QIVc) for HI antibody does not exceed the non-inferiority margin of 1.5.
Immunogenicity of QIVc to comparator TIVc (For H1N1, H3N2 and B1 strain, the comparison is between QIVc and TIV1c and for B2 i.e. alternate B strain, the comparison is between QIVc and TIV2c) was assessed in terms of percentages of subjects showing seroconversion or significant increase in HI antibody titers, three weeks (day 22) after vaccination with one dose of either QIVc,TIV1c or TIV2c Seroconversion is defined in subjects seronegative at baseline (i.e., HI titer \<1:10 at Day 1) as post-vaccination HI titer ≥1:40, and defined in subjects sero-positive at baseline (i.e., HI titer ≥1:10 at Day 1) as a minimum of a 4-fold increase in post-vaccination HI titer
Immunogenicity of QIVc to comparator TIV1c (For A/H1N1, A/H3N2 and B1 strain, the comparison was between QIVc and TIV1c and for B2 i.e. alternate B strain, the comparison was between QIVc and TIV2c) was assessed in terms of GMT in subjects (Previously vaccinated and Not previously vaccinated) measured by hemagglutination inhibition (HI) assay, three weeks after last vaccination with one or two doses of either QIVc, TIV1c or TIV2c. Non-inferiority was established if the upper bound of the two-sided 95% confidence interval (CI) for the ratio of GMTs (GMT TIV1c or TIV2c /GMT QIVc) for HI antibody does not exceed the non-inferiority margin of 1.5.
Immunogenicity of QIVc to comparator TIVc (For A/H1N1, A/H3N2 and B1 strain, the comparison was between QIVc and TIV1c and for B2 i.e. alternate B strain, the comparison was between QIVc and TIV2c) was assessed in terms of number (%) of subjects (Previously vaccinated and Not previously vaccinated) showing seroconversion or significant increase (at least a 4-fold increase in HI titer in subjects seropositive at baseline \[i.e., HI titer ≥1:10 at Day 1\] ) in HI antibody titers, three weeks after last vaccination with one or two doses of either QIVc, TIV1c or TIV2c Seroconversion was defined in subjects seronegative at baseline (i.e., HI titer \<1:10 at Day 1) as postvaccination HI titer ≥1:40, and defined in subjects seropositive at baseline (i.e., HI titer ≥1:10 at Day 1) as a minimum of a 4-fold increase in post-vaccination HI titer.

QIVc is an investigational quadrivalent influenza vaccine being developed for the prevention of influenza. It is a monoclonal antibody modality, though it is studied as a vaccine in clinical trials. QIVc is currently in Phase 3 clinical development and has not been approved by regulatory authorities.
QIVc is being developed by Novartis AG, a multinational pharmaceutical company listed on the New York Stock Exchange under the ticker symbol NVS. The company is conducting Phase 3 clinical trials to evaluate the safety and immunogenicity of QIVc in adults and children.
QIVc is in Phase 3 clinical development. Two Phase 3 trials have been completed, one in adults aged 18 years and older and another in children aged 4 to less than 18 years. QIVc is investigational and has not received FDA approval.
QIVc has been studied in two completed Phase 3 clinical trials. NCT01992094 evaluated safety and immunogenicity in 2,680 adults aged 18 and older in the United States. NCT01992107 evaluated safety and immunogenicity in 2,333 children aged 4 to less than 18 years in the United States.
QIVc is a quadrivalent influenza vaccine, meaning it is designed to protect against four influenza virus strains. It is being compared against other influenza vaccines in active-controlled clinical trials. QIVc is distinct in its development by Novartis and its specific formulation, though it belongs to the broader class of quadrivalent influenza vaccines.
