Integris BioServices

Integris BioServices is a private life sciences services company best known through its operating brand KCAS Bio, a full-service bioanalytical and biomarker contract research organization. The company supports biopharma, biotech, and animal health clients from early discovery through preclinical and clinical development to product registration, with capabilities spanning PK/TK bioanalysis, biomarkers, immunogenicity, flow cytometry, molecular assays, biodistribution, dose formulation analysis, and central lab support. KCAS Bio emphasizes both large- and small-molecule development and has positioned itself as a specialist partner for complex and emerging therapeutic modalities, including cell and gene therapies. The business operates laboratories in Olathe, Kansas and the greater Philadelphia area, plus a site in Lyon, France and a strategic alliance in Melbourne, Australia. It is backed by Vitruvian Partners and serves global drug developers rather than advancing an internal therapeutic pipeline.
