Clinical Trial Summary

The primary study objectives are:

• To demonstrate that a 2-dose regimen of ProQuad® manufactured with recombinant Human Albumin (rHA) administered at a 3-month interval to healthy children of 11 months of age at the time of Dose 1 is as immunogenic as in healthy children of 12 months of age at the time of Dose 1.

• To demonstrate that a 2-dose regimen of ProQuad® rHA administered at a 3-month interval to healthy children of 9 months of age at the time of Dose 1 is as immunogenic as in healthy children of 12 months of age at the time of Dose 1.

• To demonstrate that a 2-dose regimen of ProQuad® rHA administered at a 3-month interval to healthy children of 11 months of age and 9 months of age at the time of Dose 1 is well-tolerated compared to children of 12 months of age at the time of Dose 1.

The first primary hypothesis was that a 2-dose regimen of ProQuad® rHA, administered at a 3-month interval to children of 11 months of age, would be non-inferior in terms of antibody response rates to measles, mumps, rubella, and varicella at Day 42 following Dose 2, to the same regimen in children of 12 months of age at the time of Dose 1.

If the first primary hypothesis was demonstrated, the second primary hypothesis was that a 2-dose regimen of ProQuad® rHA, administered at a 3-month interval to children of 9 months of age, would be non-inferior in terms of antibody response rates to measles, mumps, rubella, and varicella at Day 42 following Dose 2, to the same regimen in children of 12 months of age at the time of Dose 1.

The secondary study objectives are:

• To describe the antibody titres to measles, mumps, rubella and varicella at Day 42 following Dose 1 and Dose 2 of ProQuad® rHA administered to healthy children from 9 months of age.

• To evaluate the safety profile of Dose 1 and Dose 2 of ProQuad® rHA administered to healthy children from 9 months of age.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of Participants in Arm 2 and Arm 3 Meeting Antibody Immunogenicity Response Criteria Following ProQuad® Dose 2	Immunogenicity response rates were compared in participants with baseline seronegativity from Arm 2 (received ProQuad® Dose 1 at 11 months) and Arm 3 (received ProQuad® Dose 1 at 12 months). Measles, mumps and rubella antibody levels were determined using enzyme-linked immunosorbent assay (ELISA) and varicella antibody levels were determined with glycoprotein-based ELISA (gpELISA). Response and baseline seronegativity criteria were as follows: measles antibody titre =255 mIU/mL in participants with baseline titre <255 mIU/mL; mumps antibody titre =10 ELISA Ab units/mL in participants with baseline titre <10 ELISA Ab units mL; rubella antibody titre =10 IU/mL in participants with baseline titre <10 IU/mL; varicella antibody titre =5 gpELISA units/mL in participants with baseline titre <1.25 gpELISA units/mL.	Day 132 (6 weeks after ProQuad® Dose 2)
Primary	Percentage of Participants in Arm 1 and Arm 3 Meeting Antibody Immunogenicity Response Criteria Following ProQuad® Dose 2	Immunogenicity response rates were compared in participants with baseline seronegativity from Arm 1 (received ProQuad® Dose 1 at 9 months) and Arm 3 (received ProQuad® Dose 1 at 12 months). Measles, mumps and rubella antibody levels were determined using ELISA and varicella antibody levels were determined with gpELISA.
