Recent developments in immunotherapy have demonstrated a significant clinical impact in the field of cancer treatment. However, it is well known that immune therapy works better when there are immune effector cells present in the tumour microenvironment compared to if they are absent. When the tumour lacks immune effector cells, they are called “cold” and when immune effector cells are present they are named “hot”. Preclinical studies have shown that the Lytix compound LTX-315 has the potential to make cold tumours hot and thus increase the overall patient response of combinations with other cancer treatments, for example immune checkpoint inhibitors.
Forty-two patients have so far been treated with LTX-315 alone, in two Phase I trials, and positive signals from these patients form the basis for this project. The primary objective for this project is to document in both preclinical and clinical studies that LTX-315 increase the infiltration of immune effector cells in the tumour and make the “cold” tumour “hot” in combination with immunotherapy. The clinical study will be performed in patients with Triple Negative Breast Cancer, a subtype of breast cancer. These patients have today limited treatment possibilities and the medical need for better treatments is high.
Håkan Wickholm, CEO of Lytix Biopharma says: ‘We are very pleased that the Research Council shares our view of the potential of LTX-315 and supports our work to give cancer patients a better treatment response.’’
