Summary
Research Hypothesis Lung cancer is the leading cause of cancer-related mortality in France
and in western countries, accounting for more than 1.8 million new cases and 1.5 million
deaths worldwide in 2012. Recent advances in the management of patients with Non-small Cell
Lung Cancer Patients (NSCLC) include the use of therapies targeting oncogenes but a molecular
alteration is currently found in only the half of the non-squamous NSCLC . More recently,
immune check point inhibitors (ICI), firstly targeting PD-(L)1, became available and
demonstrate an overall survival advantage over standard second-line chemotherapy both in
squamous and non-squamous NSCLC. Unfortunately, this global overall survival benefit is
driven by approximately 20% of the patient's population while a large majority of patients is
in fact progressing in the first weeks of treatment.
In the context of personalized medicine, innovative immunotherapy strategies in oncology are
based on the principle of immune-contexture and require:
- The identification of biomarkers for assessing the specific immune-contexture of each
patient (microenvironment, tumors and effector cells)
- The development of new treatments targeting their appropriate effector cells in
monotherapy or combination treatments.
The current PIONEER-Clinical study is aimed at assessing how to overcome resistance to ICIs
monotherapies or ICI in combination with platinum-based chemotherapies, with experimental
precision immunotherapies combined to Durvalumab in 2nd, 3rd or 4th line, in advanced NSCLC
progressors patients after up to 18more than 6 w. of anti PD (L) 1. for ICIs monotherapies
and after more than 12w. of anti PD(L)1 in combination with chemotherapies.
Some supplementary blood and tissue samples are aimed at identification of personalized
patients' biomarkers, correlation of them with the efficacy endpoints, in order to better
understand mechanisms of resistance and improve their future treatment.
