Lead Product in Development

Carina’s proprietary CNA3103 CAR-T cell targets LGR5, a cancer stem cell marker that is highly expressed on advanced colorectal cancer and some other cancers. CNA3103 is in Phase 1 in patients with metastatic colon cancer. In colorectal cancer patients, LGR5 expression has been correlated with poor prognosis. Cancer stem cells are a small sub-population of cells within a tumour with the ability to self-renew, differentiate into the many cell types of a tumour, initiate new tumours, and resist chemotherapy and radiotherapy (leading to relapses). By targeting cancer stem cells, it is anticipated that this therapy will reduce the tumour’s ability to generate new cancer cells, resulting in durable tumour suppression and preventing the relapses that are very common in patients with colorectal cancer. Carina’s pre-clinical studies of CNA3103 have shown promising results with complete tumour regression and no tumour recurrence following a single administration. CNA3103 has also been demonstrated to reject tumour re-challenge.
