That is nonetheless a principal focus for us and we’re actively advancing OST-HER2, our immunotherapy candidate for the prevention of recurrence of metastases in osteosarcoma. As time has advanced, we’ve additionally begun to see our immunotherapy and ADC (Drug Conjugates) platforms as potential new remedies for a lot of different strong tumors. In February, we introduced the formation of our subsidiary OS Drug Conjugates to create worth from our modern, patented silicone dioxide-based, pH-sensitive tunable antibody-drug conjugates (tADC) & different tunable drug conjugates (tDC) platform.

OST-HER2 is an immunotherapy leveraging the immune-stimulatory results of Listeria micro organism to provoke a robust immune response focusing on the HER2 protein. It really works by stimulating the immune system to supply killer T-cells (lymphocytes) that search out and destroy micro-metastases earlier than they’ll take maintain within the lungs and mind. Earlier this yr, we launched optimistic Part 2b knowledge that show statistically important leads to the first endpoint of the research, 12-month event-free survival (EFS).
Our OST-tADC platform seeks out giant, cumbersome tumors that it assaults and debulks. It incorporates pH-sensitive silicon-based linkers, SiLinkers™, to hyperlink the focusing on antibodies (or antibody fragments) and therapeutic moieties collectively whereas coating your entire bundle with pH-sensitive coating.
