PRIMARY outcome

Timeframe: 6 months

Population: Safety parameters were tabulated and analyzed descriptively in the total vaccinated (TV) population, according to the actual vaccine received. TV population is defined as all subjects who received at least one dose of study vaccine.

Number of subjects experiencing Serious Adverse Reactions (SAR), severe AR and IMR, i.e. SAEs, severe AEs (grade 3), or IMEs considered consistent with a causal association with study vaccines as of the informed consent signature date and throughout the study period in all groups.

SECONDARY outcome

Timeframe: 6 months

Population: Assessed in total vaccinated (TV) population, defined as all subjects who received at least one dose of study vaccine.Only secondary objectives included intent to compare the M5 data with the control sample which had received Sabin mOPV2 in M2 study (NCT02521974-historical control for M5). Extent of exposure: in M5 Stage II, the second dose of study vaccine were received by 47 (94%) children in Group A1H2\[2018\] and 50 (98%) children in Group A2H2\[2018\].

Number of participants experiencing any other SAE, any solicited AE, any unsolicited AEs and any IME as well as any clinical laboratory deviation considered consistent with causal association to study vaccine (primary objective) following one or two doses of either nOPV2 candidates.

SECONDARY outcome

Timeframe: 2 months

Population: Subset of subjects with baseline immunity (NAb titer) sufficiently low to enable observation of seroconversion (≤8.5 log2 i.e. ≤4-fold from assay ULOQ) at D56. Only secondary objectives included intent to compare the M5 data with the control sample of similarly aged infants and young children who had received Sabin mOPV2 in a M2 study, which was designed to serve as a historical control for M5. For further details on results corresponding to M2 study, please refer to NCT02521974.

Seroconversion rates against type 2 of one or two 106 CCID50 doses of both nOPV2 vaccine candidates in healthy children aged 1 to 5 years and of two doses of both nOPV2 vaccine candidates at both 105 and 106 CCID50 dose levels at approximately 22 weeks of age in infants previously vaccinated with 3 doses of bOPV and 1 dose of IPV, and compare this immunogenicity with a control sample of participants receiving the same vaccination schedule followed by one or two doses of Sabin mOPV2 in a prior study (M2) designed and performed to serve as a control for the current study. Seroconversion is defined as a change from seronegative to seropositive, and in seropositive subjects, as an antibody titer increase of ≥ 4 fold over baseline (Day 0) titers corrected for maternal antibodies titers where applicable/age-appropriate.

Population: Subset of subjects corresponding to 2018 Candidates cohorts. 2016 Candidate cohorts did not participate on this endpoint assessment. Only secondary objectives included intent to compare the M5 data with the control sample of similarly aged infants and young children who had received Sabin mOPV2 in a M2 study, which was designed to serve as a historical control for M5. For further details on results corresponding to M2 study, please refer to NCT02521974.

Level of viral shedding in stool at fixed time points following administration of one or two doses of both nOPV2 candidates at both 105 and 106 CCID50 dose levels in infants at approximately 18-22 weeks of age after having been previously vaccinated with 3 doses of bOPV and 1 dose of IPV, and compare this shedding to a control sample of participants receiving the same vaccination schedule followed by one or two doses of Sabin mOPV2 in a prior study designed to serve as a control for the current study. This is determined by measuring the median number of days taken to get stool cultures negative for poliovirus presence (TTCN stands for median time to culture negative). Kaplan-Meier methods were used to describe the time to cessation of shedding for any shedding (PCR detection).

Timeframe: 2 months

Population: Per the description under the Outcome Measure Description section, these groups do not match the participants arms distribution, as these results are related to the vaccine candidates behaviour in mice, not to the participating subjects. Only secondary objectives included intent to compare the M5 data with the control sample of M2 study, which was designed to serve as a historical control for M5. For further details on results corresponding to M2 study, please refer to NCT02521974.

Potential for neurovirulence of virus isolated from a subset of stool samples of infants at approximately 18-22 weeks of age after having been previously vaccinated with 3 doses of bOPV and 1 dose of IPV, and following a single dose of both nOPV2 candidates at the 106 CCID50 dose level, as measured in an animal model, and compare this with a control sample (M2 study). For each of the children / infants receiving a 106 CCID50 dose of the 2018 cohorts as well as all participants in study M2, an exploratory endpoint sample (EES) of poliovirus shed in stools following the first dose was identified, if possible, with which to perform a modified neurovirulence test in a transgenic mouse model. Data from each sample tested was summarized by group per vaccine candidate. The proportion of mice paralyzed and the odds ratio of paralysis from the single-dose assay were the primary means of comparison of neurovirulence of shed virus between each candidate and the Sabin mOPV2 control samples.
