APTEΞUS was created to provide clinicians and their patients suffering from orphan diseases, an innovative service of clinical biology that perfectly meets the emerging challenge of individualized medicine. APTEΞUS is engaged in patient-centric discovery of individualized treatments. Our technology allows the testing of thousands of molecules directly on primary cells sampled from patient with inborn error of metabolism. We can rapidly identify molecules that specifically correct the very molecular defect of the patient and give him a new opportunity to be cured.
