The main purpose of including DiviTum^® in studies performed at Mayo Clinic is to evaluate the changes in serum thymidine kinase activity, measured by DiviTum^®, in patients with hormone positive metastatic breast cancer treated with today’s standard regimens – including CDK 4/6 inhibitors. DiviTum^® measurements at the start of therapy and during treatment will be correlated to patient outcome focusing on the use of DiviTum^® as a tool for easy and early evaluation of tumor progression and overall patient survival.

"We are very pleased to collaborate with Mayo Clinic in our ambition to further strengthen our already solid documentation of the value DiviTum^® can bring to patients being treated for metastatic breast cancer.  This collaboration complements our previous studies in this field and will be important in our market introduction of DiviTum® as a tool for the monitoring of patient response to treatments within metastatic breast cancer” says Anders Rylander, CEO Biovica.

About DiviTum^®
DiviTum^® is an innovative biomarker assay developed with the aim to predict outcome and monitor treatment response in cancer therapy. The test measures the activity of the enzyme thymidine kinase-1 (TK) in a blood sample. In normal cells, TK activity is hardly detectable, but in proliferating cells, the levels increase. Since the degree of TK activity is highly associated with the rate of cell proliferation, it is a particularly suitable biomarker for measuring tumor aggressiveness. DiviTum^® has in several trials already successfully demonstrated clinical potential in evaluating and monitoring the efficacy of endocrine standard treatments for women with metastatic breast cancer. By providing key information for early identification of those patients not responding or resistant to their on-going treatment, DiviTum^® presents a non-invasive and efficacious approach to monitoring and predicting responses to standard endocrine therapies.
