Safety, Tolerability, and Immunogenicity of V419 in Healthy Infants When Given at 2, 4, and 11 to 12 Months (V419-008)

MCM Vaccines B.V.1,315 enrolled

Overview

This study will determine whether participants who receive V419 (PR5I) at 2, 4, and 11 to 12 months of age have an acceptable response to the vaccine. This study will also determine whether the immune response to V419 is similar to that of participants who received a licensed vaccine control. The primary hypothesis is that participants who receive PR5I at 2, 4, and 11 to 12 months have an acceptable response rate to all PR5I-contained antigens at one month after the Toddler dose of PR5I.

Interventions

DTaP-HB-IPV-Hib (Diphtheria, tetanus, pertussis \[acellular, component\], hepatitis B \[recombinant DNA\], polio virus \[inactivated\], and Haemophilus influenza type b conjugate vaccine \[adsorbed\]) Vaccine 0.5 mL intramuscular injection at 2, 4, and 11 to 12 months of age. Injection is to be administered in the upper anterolateral thigh, separate limb from the concomitant vaccine. PR5I is a liquid suspension hexavalent vaccine.

INFANRIX™ hexaBIOLOGICAL

Combined Diphtheria-Tetanus-acellular Pertussis \[DTaP\], Hepatitis B \[HepB\], Poliovirus \[IPV\] and Haemophilus influenzae type b \[Hib\] Vaccine 0.5 mL intramuscular injection at 2, 4 and 11 to 12 months of age. Injection is to be administered in the upper anterolateral thigh, separate limb from the concomitant vaccine. INFANRIX™ hexa is provided as 2 components (lyophilized Hib and liquid DTaP, IPV, and HepB). Prior to administration, the vaccine must be reconstituted by adding the liquid DTaP-HepB-IPV component to the vial containing the Hib pellet.

Outcomes

Primary Outcomes

Acceptability of Antibody (Ab) Response or Seroresponse Rates to All Antigens Contained in PR5I Vaccine One Month After the Toddler Dose of PR5I (11 to 12 Months of Age)

Acceptability response rates were defined as Ab titre ≥1.0 μg/mL for Haemophilus influenzae type b (Hib) (polyribosylribitol phosphate, PRP); ≥10 mIU/mL for Hepatitis (HBsAg); ≥0.1 IU/mL for diphtheria and tetanus; ≥8 (1/dil) for inactive poliovirus type (IPV) 1, 2 \& 3, and percentage of pertussis seroresponder participants (Pertussis toxoid \[PT\], Filamentous haemagglutinin \[FHA\], Fimbriae types 2 \& 3 \[FIM\] and Pertactin \[PRN\]) 1 month Post-Toddler dose of PR5I. Seroresponse was defined: (1) If pre-Dose 1 Ab concentration (cc) was \<LLOQ (lower limit of quantitation), postvaccination Ab cc was ≥LLOQ, (2) If pre-Dose 1 Ab cc was ≥LLOQ, postvaccination Ab cc was ≥prevaccination levels. Due to the timing of the occurrence of protocol violation or the availability of each antigen serology testing result, the analysis populations may not have been identical for each antigen-specific analysis at each post-vaccination visit.

Time frame: 1 month after Toddler dose of PR51 (post-toddler dose)

Secondary Outcomes

Non-inferiority of Antibody (Ab) Response Rate to Haemophilus Influenzae Type b (PRP) One Month After the 2nd Dose of PR5I (4 Months of Age) as Compared With INFANRIX Hexa

Percentage of participants with an Ab titre ≥1.0 μg/mL for Hib (polyribosylribitol phosphate, PRP) measured by radioimmunoassay (RIA) 1 month post-infant dose 2 of PR5I or INFANRIX hexa.

Time frame: 1 month after the 2nd dose (post-infant dose 2)

Superiority of Antibody (Ab) Response Rates to Haemophilus Influenzae Type b (PRP) One Month After the 2nd Dose of PR5I (4 Months of Age) as Compared With INFANRIX Hexa

Percentage of participants with an Ab titre ≥1.0 μg/mL for Hib (polyribosylribitol phosphate, PRP) measured by RIA 1 month post-infant dose 2 of PR5I or INFANRIX hexa.

Time frame: 1 month after the 2nd dose (post-infant dose 2)

Non-inferiority Ab Response Rates to PR5I Antigens One Month After the Toddler Dose of PR5I (11 to 12 Months of Age) as Compared With INFANRIX Hexa

Percentage of participants with pre-specified Ab titre for PRP, HBsAg, diphtheria, tetanus, IPV1, 2 \& 3, and percentage of pertussis seroresponder participants (PT, FHA, FIM and PRN) 1 month post-toddler dose were calculated based on the method by Miettinen and Nurminen stratified by country. Seroresponse was defined: (1) If pre-Dose 1 Ab cc was \<LLOQ, post-vaccination Ab cc was ≥LLOQ, (2) If pre-Dose 1 Ab cc was ≥LLOQ, post-vaccination Ab cc was ≥pre-vaccination levels. Due to the timing of the occurrence of protocol violation or the availability of each antigen serology testing result, the analysis populations may not have been identical for each antigen-specific analysis at each post-vaccination visit.

Time frame: 1 month after Toddler dose (post-toddler dose)

Non-inferiority of Rotavirus Response (Geometric Mean Titer, GMT) One Month After the 2nd Dose of Rotarix (4 Months of Age) Administered Concomitantly With PR5I Versus INFANRIX Hexa

Antibody titres expressed in units/mL were measured for Rotavirus IgA by Enzyme Immunoassay (EIA), 1 month after the 2nd dose of Rotarix, administered concomitantly with PR5I or INFANRIX hexa (Post-Dose 2). The 95% CI for GMT was based on the t-distribution of the natural log-transformed antibody titer.

Time frame: 1 month after the 2nd dose of Rotarix, administered concomitantly with PR5I or INFANRIX hexa (Post-Dose 2)

Number of Participants Who Experienced an Adverse Event (AE) From Day 1 to Day 15 After Any Vaccination

Injection-site and systemic AEs were reported daily on the Vaccination Report Card (VRC) by the parent(s) or legal representative from Day 1 (D1) to D15 after each vaccination. Solicited injection site and systemic AEs were reported daily from D1 to D5 after each vaccination. AEs at injection sites were always considered as vaccine-related (V-related) (Injection-Site Reactions \[ISRs\]). The investigator had to assess whether systemic AEs were related or not to the vaccine. All AEs (related and unrelated) are displayed here.

Time frame: Solicited AEs: up to 5 days (Days 1-5 after any vaccination); unsolicited AEs: up to 15 days (Day 1-15 after any vaccination)

Percentage of Participants Reporting Solicited ISRs From D1 to D5 After Any Vaccination

Adverse events at injection sites were always considered as related to vaccine (Injection-Site Reactions \[ISRs\]). Solicited ISRs were defined as injection-site erythema, injection-site pain, and injection-site swelling occurring from D1 to D5 after vaccination.

Time frame: Up to 5 days (Day 1 to Day 5 following vaccination)

Percentage of Participants Reporting Unsolicited ISRs From D1 to D15 After Any Vaccination

Adverse events at injection sites were always considered as related to vaccine (Injection-Site Reactions {ISRs\]). Unsolicited ISRs occurring from Day 1 (D1) to D15 after any vaccination were reported daily on the VRC by the parent(s) or legal representative. Unsolicited ISRs with incidence ≥1% are reported below.

Time frame: From D1 to D15 after any vaccination

Percentage of Participants Reporting Solicited Adverse Events (AEs) From D1 to D5 After Any Vaccination

Solicited systemic AEs were defined as crying, decreased appetite, irritability, pyrexia (rectal temperature ≥38.0°C), somnolence, and vomiting occurring from D1 to D5 after vaccination. The investigator had to assess whether these systemic AEs were related or not to the vaccines. All (related and unrelated) are displayed here.

Time frame: Up to 5 days (from D1 to D5 after any vaccination)
