AI summary: who the study is looking for

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for adults with non-small cell lung cancer (stage II-IV) who can have surgery after first receiving treatment that includes an immune checkpoint inhibitor.

Age
18 years or older
Sex
Men and women
Disease stage
Non-small cell lung cancer, stage II-IV (oligometastatic disease allowed), confirmed by tissue or cell tests, and thought operable with the aim of removing all of the disease after neoadjuvant treatment with an immune checkpoint inhibitor, by a local tumor board decision.
Earlier treatment
Planned neoadjuvant systemic therapy that includes an immune checkpoint inhibitor.

Original description
First discovered in 1997 the torque teno virus (TTV) can be found in the vast majority of the human population throughout their lifetime. The TTV levels correlate with infectious diseases and organ rejection and are therefore currently being investigated as a tool to optimize the management of patients after solid organ transplantation (SOT). While TTV levels are already tested to guide immunosuppressive therapy its significance for oncologic patients is unclear. In recent years immune checkpoint inhibitors (ICIs) are increasingly implemented in multimodal therapy approaches for patients with non-small-cell lung cancer (NSCLC). Since ICI and TTV levels depend on T-cell function, the TTV load may be a relevant biomarker for the treatment response as well as complication risk after ICI therapy. Current standard imaging using PERCIST and RECIST criteria is prone to misinterpretation of treatment response of ICI therapy due to pseudoprogression and nodal immune flaring. This study aims to prospectively analyze TTV levels in NSCLC patients before, during and after neoadjuvant chemo-immunotherapy and correlate inter- and intraindividual changes in TTV levels with response rates observed on PET/CT restaging and histopathological response rates as well as postoperative outcome.Read full original descriptionShow less

Efficacy of Torque Teno Virus as a Biomarker for Predicting Treatment Response of Immune Checkpoint Inhibitor Therapy and Postoperative Outcome in NSCLC Patients - A Prospective Non-interventional Single-arm Study

Inclusion: Histologically or cytologically verified NSCLC stage II-IV (OMD) according to UICC TNM8 edition considered operable in curative intent after neoadjuvant systemic therapy containing immune checkpoint inhibition by local multidisciplinary tumor board (MDT) decision; ECOG < or = 1 Staging with PET/CT and cMRI/CCT Written informed consent.
