A/H1N1 Immunogenicity and Safety in Infants, Children and Adolescents

October 7, 2015 updated by: Ology Bioservices

An Open-Label Phase 1/2 Study to Assess the Immunogenicity and Safety of Two Different Dose Levels of H1N1 Pandemic Influenza Vaccine in Healthy Infants, Children and Adolescents Aged 6 Months to 17 Years

The purpose of this study is to determine the preferred dose of H1N1 pandemic influenza vaccine in a pediatric population, aged 6 months to 17 years, based upon assessments of immunogenicity and safety.

  • Subject is 9 to 17 years (Stratum A), 3 to 8 years (Stratum B), 12 to 35 months (Stratum C) or 6 to 11 months of age (Stratum D) at the time of screening
  • Subject was born at full term of pregnancy (>= 37 weeks) with a birth weight >= 2 kg (Strata C and D) Subject / parent(s) / legal guardian(s) understand(s) the nature of the study and is / are willing to comply with the requirements of the protocol (e.g. return for follow-up visits, completion of the subject diary)
  • If female of childbearing potential, subject presents with a negative urine pregnancy test within 24 hours prior to the first vaccination and agrees to employ adequate birth control measures for the duration of the study
  • Subject is generally healthy, as determined by the investigator's clinical judgment through collection of medical history and the performance of a physical examination
  • Subject is physically and mentally capable of participating in the study

Exclusion Criteria:

  • Subject has participated in another clinical study involving an investigational drug, biological product or device within 30 days prior to study enrollment or is scheduled to participate in another clinical study involving an investigational drug, biological product or device during the course of this study
  • Subject has a history of exposure to A/H1N1/California/07/2009 virus or a history of vaccination with A/H1N1/California/07/2009 antigen or a closely related influenza virus antigen

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Dose A (3.75 µg HA antigen, 0.25 mL)
Within each age stratum (4 age strata) subjects will be randomized 1:1 to receive two vaccinations of either Dose A (3.75 µg) or Dose B (7.5 µg) of H1N1 pandemic influenza vaccine at a 21-day interval.
2-dose priming at a 21-day interval, intramuscular injection in either the upper arm or thigh, depending on the subject´s age
Experimental: Dose B (7.5µg HA antigen, 0.5 mL)
Within each age stratum (4 age strata) subjects will be randomized 1:1 to receive two vaccinations of either Dose A (3.75 µg) or Dose B (7.5µg) of H1N1 pandemic influenza vaccine at a 21-day interval. A booster vaccination with a licensed seasonal trivalent influenza vaccine for the season 2010/2011 will be administered to at least 30 subjects in each age stratum (who have received Dose B) at 360 days after the first vaccination.
2-dose priming at a 21-day interval, intramuscular injection in either the upper arm or thigh, depending on the subject´s age
Booster vaccination at Day 360 after first vaccination (only in subjects who received the 7.5 µg dose of the H1N1 pandemic influenza vaccine)
