Tumor genomic profiling and PD-L1 testing mean lung cancer management can be tackled through a personalized approach. Targeted therapies and immunotherapy are necessary to improve survival and preserve the patients' quality of life. Early access to innovation before marketing authorization (MA) is possible in France through clinical trials and an early-access program called a Temporary Authorization for Use (ATU), which is a unique regulatory system in Europe. This study aims to assess the impact of early access to innovation through clinical trials and ATUs in thoracic oncology. Data from clinical trials between 2018 and 2021 and ATUs between 2005 and 2019 were collected internally and assessed for drugs in thoracic oncology, with specific focus on 2 ATUs, respectively, atezolizumab and durvalumab. From 2018 to 2021, the National Agency for the Safety of Medicines and Health Products authorized 145 clinical trials in lung cancer. Between 2005 and 2019, 19 drugs obtained an EU MA or an MA extension for a therapeutic indication in lung cancer. During this period, 11 of these drugs were granted an ATU, corresponding to 6851 patients treated. Of this total number of patients, data were collected for 33.1% and 71.2%, who received durvalumab and atezolizumab, respectively. Real-life efficacy data were consistent with the clinical trial data. Over the past 15years, clinical trials and the French early access program have allowed considerable early access to therapeutic innovation in real life for patients, especially in thoracic oncology.
