Summary

This non-interventional single-center explorative biomarker study aims at longitudinal comprehensive characterization (molecular genetics, immunological, morphological, image-based and microbial features) of the patient (host) and tumor as well as changes during standard treatment and in case of recurrent disease in inoperable stage III non-small cell lung cancer (NSCLC). Comprehensive analysis will include peripheral blood cellular and humoral immunophenotyping, circulating tumor DNA and gut/saliva microbiota analyses. 18F-FDG-PET/CT before, 6 weeks, 6- and 12-months after chemoradiotherapy as well as daily in course of radiation treatment cone-beam-CT and/or MRI imaging are included for morphological analysis. This study will provide valuable information of predictive biomarkers in patients with stage III NSCLC treated with durvalumab maintenance treatment after concurrent chemoradiotherapy.

Description

The study will enrol 40 patients with stage III inoperable non-small cell lung cancer (NSCLC) who received standard chemoradiotherapy followed by maintenance therapy with PD-L1 inhibition (durvalumab) according to the current European Medicines Agency (EMA) approval.

The oncological treatment is carried out according to the international standards of radiation oncology/medical oncology. These are implemented by the department of radiation oncology at the University Hospital Munich (LMU) in their SOPs. Therefore, all patients will be treated with concurrent platinum-based chemoradiotherapy followed by durvalumab maintenance treatment 12 months after the end of chemoradiotherapy at the department of radiation oncology (University Hospital Munich (LMU)). Comprehensive characterization of all patients includes immunophenotyping of peripheral blood mono-nuclear cells, ctDNA as well as gut/saliva microbiome analyses and will be performed before, after 15 fractions of radiotherapy, at the end of concurrent chemoradiotherapy as well as 3-, 6- and 12 months after start of durvalumab.

18F-FDG-PET/CT will be performed 5-10 d before start of radiotherapy, 6 weeks, 6 months,12 and 24 months after the end of chemoradiotherapy. Lung function will be assessed before start of radiotherapy, at the end and 6 weeks after chemoradiotherapy as well as 3-, 6- and 12, 18, 24 months after start of durvalumab.

Follow-up will be performed by the department of radiation oncology at the University Hospital Munich (LMU) according to the clinical SOPs.
