Sanofi Pasteur H5 Vaccine
• Vaccine candidate manufactured using reverse genetics under NIH contract
• Inactivated vaccine received in March• Adult trial began April at 3 VTEUs
– 7.5, 15, 45, 90 mcg vs. placebo; 2 doses
• Enrollment completed mid May• Final results expected in late summer• Separate trials planned in elderly and
children, 2 dose regimen, dosage based on adult data
Chiron H5 Vaccine
• Vaccine candidate manufactured using reverse genetics under NIH contract
• 10,000 doses
• Vaccine anticipated late Fall 2005
• Clinical trial plan: adults, elderly and children
• 2 dose regimen, ~ 1 month apart
H5 Vaccine Dose Optimization StrategiesRoute• Intramuscular (IM) versus Intradermal (ID)
administration of inactivated H5 vaccine. • Phase I protocol filed to FDA• Trial start date July (planned)• Data expected Q3 2005
Adjuvants• Subcontract to Baxter to produce whole virus
inactivated H5 vaccine (Vero) +/- alum• Discussions with Chiron and Sanofi Pasteur
ongoing
GSK TIV Clinical Trial
NIAID rapidly initiated a Phase III trial to evaluate safety and immunogenicity of GSK’s inter-pandemic Fluarix® vaccine in healthy adults:
-- Trial began in Dec. 2004
-- 952 subjects enrolled in 5 days
-- Trial conducted through VTEUs
-- BLA submitted May 25th
Non-egg based technologies
NIAID supports projects aimed at developing alternatives to production of influenza vaccine in eggs:
- Recombinant protein
- Virus-like particles
- Cell culture-based technology
- Alphavirus vector
- DNA based vaccines
