Matrix-M1 adjuvant negative in GLP Ames and in vitro CHO micronucleus assays; in vivo testing judged unnecessary
“The confirmatory GLP-compliant bacterial reverse mutation assay and Mammalian Cell Micronucleus assay in CHO Cells with Matrix-M1 confirmed the absence of any indication for a genotoxic potential of Matrix-M1. Further in vivo studies were therefore not considered necessary.”
Not conducted (WHO vaccine and adjuvanted vaccine guidelines)
“No carcinogenicity studies have been performed with the SARS-CoV-2 rS vaccine and Matrix-M1 adjuvant in accordance with the WHO Guidelines on Non-clinical Evaluation of Vaccines (2005) and Guidelines on the Non-clinical Evaluation of Vaccine Adjuvants and Adjuvanted Vaccines (2014).”

Reproductive & developmental
Rat DART (dosing before mating and in gestation): no effects on reproduction, embryo-fetal or postnatal development to day 21
“The DART study confirmed that SARS-CoV-2 rS + Matrix-M1 or Matrix-M1 does not affect reproductive or developmental parameters and no adverse findings on pregnancy/lactation, or development of the embryo/foetus and offspring through post-natal Day 21 were identified.”
Not conducted (WHO vaccine guideline); physiological functions assessed within the rabbit repeat-dose study
“Safety pharmacology studies were not conducted with SARS-CoV-2 rS with Matrix-M1 adjuvant vaccine, which is in line with the recommendation of the WHO Guidelines on Non-clinical Evaluation of Vaccines (2005), also given the availability of supporting non-clinical and clinical data, which indicated that the vaccine did not affect physiological functions other than those of the immune system.”

Matrix-M1: GLP micronucleus assay in CHO cells negative
“The confirmatory GLP-compliant bacterial reverse mutation assay and Mammalian Cell Micronucleus assay in CHO Cells with Matrix-M1 confirmed the absence of any indication for a genotoxic potential of Matrix-M1. Further in vivo studies were therefore not considered necessary.”
Not conducted (judged unnecessary after negative in vitro results)
“The confirmatory GLP-compliant bacterial reverse mutation assay and Mammalian Cell Micronucleus assay in CHO Cells with Matrix-M1 confirmed the absence of any indication for a genotoxic potential of Matrix-M1. Further in vivo studies were therefore not considered necessary.”
