Cynbiose can assess the efficacy of your therapeutics or vaccine in a translational non-human primate (NHP) model. This model is relevant to test innovative or repurposed drug candidates as well as aerosoltherapies.


  • Cynomolgus macaque (Macaca fascicularis)
  • African green monkey (genus Chlorocebus)


  • Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) / COVID-19 strains (Primary strain, various European D614G variants, UK variant,  South-African variant, Brazilian variant, Delta variant, Omicron original and BA5 subvariant)
  • Infection method : intratracheal, intranasal pulverization

Type of test item

  • Vaccines
  • Antibodies, immunotherapies, antiviral candidates, small molecules
  • Combined treatments
  • Aerosoltherapies & inhaled products


  • Efficacy assessment of vaccines or therapeutics
  • Evaluation of systemic or topical (incl nebulization) administrations


  • Clinical follow-up
  • Core body temperature : continuous monitoring using an implantable data logger
  • Clinical pathology : biochemistry and complete blood count with differential) in a BSL1/2/3 setting thanks to state-of-the-art biological analyzers
  • Sampling : Bronchoalveolar lavage, Nasal & nasopharyngeal swabs, blood sampling, feces
  • Immunomonitoring
  • Viral detection and quantification by RT-qPCR
  • Viral titration using  using the Median Tissue Culture Infectious Dose (TCID50) assay
  • Assessment of the host response by seroneutralization assays
  • Histopathology
  • Custom readouts & biomarkers
