Using the body's immune system to help fight cancer
AZ Leadership in Immuno-Oncology
The promise of Immuno-Oncology (IO) is based on the knowledge that the immune system is constantly searching for, assessing, and eliminating foreign particles from the body.1,2 Yet, sometimes rogue cells slip past this immune surveillance and become cancers.2 By providing the immune system with tools to both unmask tumours and strengthen our body’s ability to attack harmful cells, IO therapies enable the immune system to recognize and respond. 1,3
AstraZeneca’s IO portfolio is anchored by immunotherapies that have been designed to overcome the tumour’s efforts to evade the immune system, such as through the targeted inhibition of immune checkpoints, and through the scientifically driven combination of multiple immune system-stimulating agents, including chemotherapies, small molecules, and other immunotherapies. 4,5,6
AstraZeneca is an industry leader in the development of biologics and our broad pipeline has been developed to deliver a portfolio of breakthrough IO therapies across multiple tumour types, in different stages of disease, and in multiple lines of therapy.7
Our IO Vision
We are pursuing a comprehensive clinical trial programme that includes IO monotherapy and IO in combination with chemotherapies, small molecules, and other immunothrapies in multiple tumour types, stages of disease, and lines of therapy. We are using biomarkers as a decision making tool to define the best potential treatment path for a patient. Our vision is that IO will play a critical role in continuing to redefine the cancer treatment paradigm.
Bringing the Benefit of IO to the Right Patients
Success in IO will hinge on the ability to identify which therapy may be best for each patient. AstraZeneca is leading the field in this area, delivering the first cross-industry data sets to enable the right treatment decisions to be made for patients.8,9 This is increasingly important when several treatment options are available for a single patient population. 10,11
