In vivo DMPK Services

Flexibility in study design and meeting demanding time lines is the strength of the GBA Pharma in vivo team. We offer DMPK studies in mice, rats, guinea pigs and hamsters. Further preclinically relevant species (e.g. dog, monkey) are available in cooperation with our partners. The service offering includes complete workflow studies (in-life part, bioanalysis and PK evaluation).
