Lung cancer is one of the most common types of cancer in Germany, with 56,839 new cases and 45,072 deaths annually. Approximately 70% of patients with non-small cell lung cancer (NSCLC) are diagnosed at an advanced stage and suffer from comorbidities and symptoms such as fatigue, tiredness, and loss of strength. The standard first-line treatment for metastatic NSCLC includes platinum-based chemoimmunotherapy followed by immunotherapy maintenance. Exercise can have positive effects on symptoms such as shortness of breath, fatigue, quality of life, and physical fitness. However, there is a lack of current scientific evidence for the effectiveness of exercise in advanced lung cancer patients. No current trial investigated exercise in advanced NSCLC receiving immunotherapy so far. The BREATH-study is a prospective 3-arm randomized controlled trial (RCT). In total, the investigators plan to recruit 104 patients. A 2:1:1 randomization will be performed with three study groups: a control group and two exercise therapy groups (strength+endurance exercise/only endurance exercise). One group receives individual endurance training and the other group a combination of individual endurance and strength training. Both treatment groups will be treated twice a week for 12 weeks. The control group will initially receive standard treatment without exercise for 12 weeks and will then be randomized into one of the other two study groups with exercise twice a week for 12 weeks. This approach allows for a sufficiently large sample for comparisons between exercise therapy and the control group, as well as between the two exercise therapy approaches. The primary aim is to investigate the impact of exercise on V02peak. Secondarily endpoints aim to investigate changes in physical function, patient related outcomes and cardiac function before and after exercise.

Exercise
West German Cancer Center (Department of Palliative medicine and Department of Medical Oncology), University Hospital Essen
Essen, North Rhine-Westphalia, Germany
Maximum oxygen uptake (VO2 peak [ml/min/kg])
The primary goal is to achieve an improvement in performance (VO2 peak\[ml/min/kg\]) from T0 (enrolment) to T1 (12 weeks) through exercise compared to the standard treatment. The one-sided alternative hypothesis of a larger improvement in the two treatment groups compared to the control group will be tested statistically as a confirmatory analysis.
Time frame: assessed at Baseline, after 12 weeks and 24 weeks of enrolment
Functional Assessment of Chronic Illness Therapy - Fatigue (FACT-F)
The FACT-F is a 13-item questionnaire to assess fatigue in cancer patients. Subscale are physical well-being, social/family well-being, emotional well-being, functional well-being and the fatigue subscale. Based on the subscale the FACIT-F trial outcome index (TOI) Score range 0-108, FACT-G total score (Score range 0-108) and FACIT-F total score (Score range 0-160) can be calculated. The higher the score, the better the Quality of Life.
Time frame: assessed at baseline, after 12 weeks and 24 weeks of enrolment
European Organisation for Research and Treatment of Cancer (EORTC QLQ C30)
The EORTC QLQ Core Questionnaire is a 30-item instrument meant to assess some of the different aspects that define the quality of life of cancer patients (e.g., physical function, emotional function, symptom scales, and Quality of Life). High scores for functional scales (score 0-100) represent a high level of functioning, high scores for the global health status represent a high quality of life (score 0-100), high scores for symptom scales (score 0-100) represent a high level of symptomatology.
Time frame: assessed at baseline after 12 weeks and 24 weeks of enrolment
European Organisation for Research and Treatment of Cancer Lung cancer module (EORTC-LC13)
The LC13 is a modular supplement to the EORTC-C30 for assessment of symptoms in clinical lung. cancer trials. The scoring range is between 0 to 100, a high score indicating a high level of symptomatology.
Time frame: assessed at baseline, after 12 weeks and 24 weeks of enrolment
Arterial blood pressure
Change during study participation (mmHg)
Time frame: assessed at Baseline, after 12 weeks and 24 weeks of enrolment
Change in ECG
Changes in 12-lead resting ECG, including PQ \[ms\], QRS \[ms\], and QT \[ms\] intervals
Time frame: assessed at baseline, after 12 weeks and 24 weeks of enrolment
Adherence to exercise intervention
The exercise physiologist monitored adherence to the supervised sessions. Based on the absolute numbers of scheduled exercise sessions, both absolute and percentage-based adherence can be calculated and compared between study arms.
Time frame: Through study completion, an average of 12 weeks
Drop-out rate
All withdrawals will be considered as dropouts, with reasons noted. Compare the total number of dropouts in each study arm. This provides a straightforward comparison of the raw dropout counts between groups. Also, calculate the percentage of participants who dropped out in each study arm relative to the total number of participants initially assigned to that arm. This allows for a comparison of dropout rates relative to the initial sample size and compared between study arms.
Time frame: Through study completion, an average of 12 weeks
Recruitment rate
The recruitment rate quantifies the speed of participant enrollment for a study.
Time frame: At Baseline
Serious Adverse Event/Adverse Events
Safety analyses will be based on Adverse Events (AEs), Serious Adverse Events (SAEs) after the Common Terminology Criteria for Adverse Events (CTCAE) v5.0
Time frame: Through study completion, an average of 12 weeks
Therapy response
Therapy response in the next computer tomography (analogous to RECIST v1.1)
Time frame: Baseline and after 12 weeks
Treatment Toxicity
Treatment toxicity encompasses the adverse effects experienced by individuals undergoing chemotherapy and exercise regimens concurrently. These effects may manifest as physical symptoms such as fatigue, nausea, muscle weakness, and decreased immune function, which can impact overall well-being and treatment adherence. Monitoring and managing toxicity levels are crucial to ensure patient safety and optimize treatment outcomes. Additionally, integrating exercise interventions alongside chemotherapy may pose unique challenges, as physical activity can exacerbate certain side effects or interact with treatment efficacy. Therefore, careful monitoring and personalized exercise prescriptions are essential to mitigate toxicity risks and enhance the overall tolerability and effectiveness of combined therapy approaches. Toxicity will be reported with CTCAE v5.0
