RESUMO
Decisions on market authorization (MA) and reimbursement have different durations across countries because of health technology assessment (HTA) procedures and negotiations between manufacturers and national authorities. To overcome this delay, France has implemented a Temporary Authorization for Use (ATU) program that allows early access to drugs before MA, in order to treat patients with unmet medical needs. The objectives of our study were to establish the added therapeutic benefit (ATB) of ATUs for solid tumors and to investigate the correlations between three tools evaluating ATB and survival outcomes and drug costs. Data on ATUs granted from January 2009 to December 2019 to treat solid tumors were analyzed. An assessment of their ATB was conducted using the American Society of Clinical Oncology-Value Framework (ASCO-VF), the European Society for Medical Oncology-Magnitude Clinical Benefit Scale (ESMO-MCBS) and the French HTA criterion, clinical added value (CAV). The latter score determines reimbursement and national market access. Thirty-five drugs in 39 indications were granted ATUs. All of them obtained MA and derived a clinical benefit to be reimbursed by the Social Security. Twenty-eight (71.8%) had CAV compared to preexisting therapies. 24/38 (63.2%) had a 4-5 ESMO-MCBS score and 19/33 (57.6%) had an ASCO-VF score over 45. No correlations were found between cost, PFS, OS, CAV and ASCO-VF score, while high ESMO-MCBS scores were correlated to OS. In conclusion, many patients were treated with innovations before MA thanks to ATU, although there are discrepancies between ATB scales, hence the importance of international collaboration in the evaluation of innovative therapies.

PURPOSE: 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. METHODS: 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. RESULTS: 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. CONCLUSION: Over the past 15 years, 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.

Human microbiota plays a key role in preserving homeostasis; therefore, alteration in its composition is associated with susceptibility to various diseases. Recent findings suggest that gut microbiota may influence response to cancer treatment, especially immune checkpoint blockers (ICBs). The development of ICBs has changed outcomes of patients with cancer and has allowed sustained recovery. Unfortunately, some patients do not respond to ICBs, and microbiota may be a promising new biomarker to identify patients who will have benefit from ICBs. This review presents relationship between microbiome composition or microbiota-derived metabolites and response to ICBs or immune-related adverse events. Furthermore, we will present different strategies to modulate microbiota composition in patients to enhance ICB efficacy or dampen their toxicities which could lead to the emergence of interesting complementary treatments.
