Oncophenomics (previously Theranosis Life Sciences) is a personalized medicine startup addressing unmet needs in cancer diagnostics, prognostics and theranostics. We are developing microfluidics based lab-on-a-chip medical devices that can detect rare cells such as circulating tumor cells in a simple blood sample drawn from a cancer patient (also known as liquid biopsy) for monitoring the treatment efficacy, predict clinical outcomes and post treatment follow up (surveillance) for cancer recurrence in the form of secondary metastasis. Our patent pending advanced microfluidics chip is designed in such a way so as to capture specific populations of rare cells and perform downstream characterizations. It can be extended beyond cancer research, for example rare fetal cells in maternal blood circulation, circulating endothelial cells in atherosclerosis etc.
