Cervarix: genotox, carcinogenicity and repro: done or skipped?

human papillomavirus bivalent (types 16, 18) vaccine, recombinant, AS04-adjuvanted · HPV 16/18 L1 VLPs; TLR4 (AS04 adjuvant)
Genotoxicity
Vaccine not tested; MPL adjuvant negative in Ames, CHO clastogenicity and in vivo micronucleus
“The in vitro mutagenicity (Ames) and clastogenicity (CHO cells) tests, and in vivo micronucleus assay demonstrated no genotoxic potential of the MPL adjuvant.”
✓ VerifiedEMA assessment report, p. 12Source ↗
Carcinogenicity
Not conducted; accepted as the vaccine is L1 protein without HPV oncoproteins
“The mutagenic and carcinogenic potential of the Cervarix vaccine was not further evaluated, which is accepted since the vaccine is based on L1 protein and HPV oncoproteins are absent.”

Reproductive & developmental
Rat combined fertility, embryo-fetal and pre/postnatal study with vaccine and AS04: no effects
“The reproductive toxicity study in CD rats did not show any effects of vaccination or AS04 administration on fertility, embryofoetal development and pre- and post-natal development.”
✓ VerifiedEMA assessment report, p. 53Source ↗
Safety pharmacology
Dedicated studies: vaccine in anaesthetised rats, MPL in dogs; no cardiovascular or respiratory effects
“Safety pharmacology studies were performed on HPV-16/18 L1 VLP AS04 in rats and on MPL in dogs.”

Genotox: Ames
MPL adjuvant: Ames negative (vaccine not tested)
“The in vitro mutagenicity (Ames) and clastogenicity (CHO cells) tests, and in vivo micronucleus assay demonstrated no genotoxic potential of the MPL adjuvant.”
✓ VerifiedEMA assessment report, p. 12Source ↗
Genotox: in vitro mammalian
MPL adjuvant: chromosomal aberration (CHO cells) negative
“The in vitro mutagenicity (Ames) and clastogenicity (CHO cells) tests, and in vivo micronucleus assay demonstrated no genotoxic potential of the MPL adjuvant.”
✓ VerifiedEMA assessment report, p. 12Source ↗
Genotox: in vivo
MPL adjuvant: in vivo micronucleus negative
“The in vitro mutagenicity (Ames) and clastogenicity (CHO cells) tests, and in vivo micronucleus assay demonstrated no genotoxic potential of the MPL adjuvant.”

Carcinogenicity model
Not conducted (L1 protein vaccine without HPV oncoproteins)
“The mutagenic and carcinogenic potential of the Cervarix vaccine was not further evaluated, which is accepted since the vaccine is based on L1 protein and HPV oncoproteins are absent.”
✓ VerifiedEMA assessment report, p. 53Source ↗
Carcinogenicity timing
Not required (L1 protein vaccine without HPV oncoproteins)
“The mutagenic and carcinogenic potential of the Cervarix vaccine was not further evaluated, which is accepted since the vaccine is based on L1 protein and HPV oncoproteins are absent.”
✓ VerifiedEMA assessment report, p. 53Source ↗
hERG / QT
No effects on blood pressure, heart rate, ECG or respiration in anaesthetised rats
“Intramuscular administration of 0.1ml/animal of the HPV-16/18 L1 VLP AS04 vaccine did not produce any treatment-related effects on blood pressure, heart rate, ECG (lead II) or respiration depth and rate”
