VitroScan – Better Informed Treatment Decisions for Cancer Patients

VitroScan is a Dutch biotech company founded in 2016 and based at the Leiden Bio Science Park. VitroScan develops fast and accurate predictive testing for multiple cancers and treatments to support better informed treatment decisions for cancer patients.

Treatment decisions for cancer patients become increasingly more complex. Innovative new treatment options, including immunotherapy, and cellular therapies have the potential to offer a great benefit to cancer patients. While established treatments already improved the care for cancer patients for a long time. In this continuously changing landscape, diagnostics are crucial to delivering the best treatment for each individual patient. VitroScan develops fast and accurate predictive testing for multiple cancers and treatments.

Our unique technology platform uses high-content 3D imaging for sensitive detection of therapeutic responses. A growing database is correlating ex vivo drug sensitivity and clinical outcomes for several cancer types.

The team consists of successful entrepreneurs, experts in the fields of bioinformatics, computer vision, programming, and 3D cell culture and drug testing, with extensive networks in fields of clinical oncology, pharma, and (bio) information technology.
