Fendrix: how long were the pivotal tox studies?
hepatitis B vaccine (rDNA), AS04C-adjuvanted · HBsAg VLPs; TLR4 (AS04C adjuvant)
Longest pivotal study
2 (14-day IV MPL study in Beagle dog; rabbit vaccine study duration not stated)
“Repeated-dose toxicity studies were presented, up to 7 days in rats and 14 days in Beagle dogs, where MPL was given once daily by the intravenous route, maximising the exposure.”
Pivotal GLP studies
Rabbit IM repeat-dose vaccine study; MPL alone IV daily up to 7 days (rat) and 14 days (Beagle dog)
“Repeated-dose toxicity studies were presented, up to 7 days in rats and 14 days in Beagle dogs, where MPL was given once daily by the intravenous route, maximising the exposure.”
Route in tox
Intramuscular (vaccine, rabbit); intravenous for MPL alone
“Observation of local tolerance in the repeat-dose toxicity study with intramuscular administration in rabbits pointed to minor reactions at the injection sites characterized by an inflammatory reaction with mixed-cell or mononuclear cell infiltrate, which disappeared one month after the last injection.”
