Study summary

The goal of this observational study is to learn how fatigue changes during lung cancer treatment and how it relates to physical activity levels in adults with locally advanced, inoperable, or metastatic lung cancer who are starting chemotherapy and/or immunotherapy. The main questions to answer are:

  • How do fatigue and physical activity levels change throughout lung cancer treatment?
  • How are changes in fatigue related to physical activity levels on the short- and long term?

Participants will:

  • Complete questionnaires on fatigue, breathlessness, sleep quality, quality of life, stress, anxiety and depression at multiple time points.
  • Wear activity monitors during four measurement periods to assess daily physical activity.
  • Complete brief daily smartphone questionnaires on fatigue, breathlessness, pain, and perceived ability to walk.
  • Wear a smartwatch throughout the study.
  • Undergo physical assessments, including a 1-minute sit-to-stand test, a thigh muscle strength test, and a frailty assessment.
  • Attend six study visits over the course of the study, some of which may be scheduled alongside routine hospital appointments.

Study population

This study will include patients with locally advanced irresectable or metastatic lung cancer, who are planned to undergo systemic treatment (chemotherapy and/or immunotherapy).

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Locally advanced irresectable or lung cancer (all histologies including NSCLC and SCLC).
  • ≥18 years.
  • performance status of ≤2 (a lower score indicates a higher performance status), assessed by the clinician (10).
  • Planned to start a systemic treatment consisting of chemotherapy and/or immunotherapy. Patients who receive radiotherapy, concurrently or sequentially, within a multimodality treatment approach for locally advanced lung cancer are allowed.
  • Ability to give .

Exclusion criteria

Exclusion Criteria:

  • Being planned for primary radiotherapy with radical intent only or treatment with targeted therapies (mostly tyrosine kinase inhibitors (TKI's)).
  • Having complicated or unstable bone (as judged by the clinician).
  • Unstable heart disease, including unstable congestive heart failure, arrythmia, or myocardial infarction diagnosed within the last 3 months.
  • Other in the last 2 years (except for adequately treated basal cell, superficial or in situ cancer of the bladder or the cervix).
  • Have musculoskeletal problems precluding them to be physically active.
  • Not understanding and speaking Dutch.
Terms in these criteria, in plain language(5)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

Line of therapy

A line of therapy is one course of treatment, which may combine several drugs. First-line is the first course given; second-line follows when that stops working or is not tolerated.

“Two prior lines” means two courses that count separately under the study’s rules — not simply two drugs. Ask the study team if you are unsure how yours are counted.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

What researchers measure

Primary outcomes

  1. Cancer-related fatigue (FACIT-F)

    Cancer-related fatigue (CRF) will be measured using the FACIT-F and EMA. The Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) is a 13-item questionnaire with each item answered on a 5-point rating scale, which has been validated and frequently used in cancer populations. The questionnaire is based on a 7-day recall period. Scores range between 0 and 52, where higher scores represent lower fatigue levels. The minimum important difference for the FACIT-F is between 3 to 4 points.

    Time frame: From enrollment until 4 weeks after the end of treatment

  2. Cancer-related fatigue (EMA)

    Regarding EMA, patients will install the m-path application on their smartphone. Patients will be asked to fill in 3 prompts per day for 15 (M1 and M2) or 8 (M3 and M4) consecutive days, answering questions about fatigue ("I feel fatigued right now" from 1 (not at all) to 7 (very)). The 3 prompts will be sent at a random time within 3 blocks per day (between 8h and 10h, between 12h and 14h, and between 18h and 20h). Prompts will be available for 30 minutes and a reminder will be sent after 15 minutes. Daily symptom rating will be calculated by taking the average of the 3 prompts and will be used for further analyses.

    Time frame: From enrollment until 4 weeks after the end of treatment

  3. Physical activity

    Physical activity (PA) will be measured during one or two week(s) (depending on the treatment phase) using an Actigraph GT3X and Dynaport Movemonitor+, both validated accelerometers. Following recommendations on wear location, participants will be asked to wear the devices at the waist (on the same belt) during daytime and switch the Actigraph GT3X to the non-dominant wrist during the night (to measure sleep duration). Valid PA data is considered when a patient has at least 8 hours wear time during waking hours. The average daily step count (based on Dynaport Movemonitor+) and minutes of MVPA (based on Actigraph GTX3) per day of all valid days are the PA outcomes.

    Time frame: From enrollment until 4 weeks after the end of treatment

Secondary outcomes

  1. Symptoms of Dyspnea

    Symptoms of dyspnea occurring during daily life activities will be assessed through the Chronic Respiratory Disease Questionnaire Self-Administered Standardized (CRQ-SAS).

    Time frame: From enrollment until 4 weeks after the end of treatment

  2. Quality of Life (general)

    The European organization for the Research and Treatment of Cancer Questionnaire (EORTC QLQ-C30) is a clinically valid and useful tool for assessing quality of life in lung cancer patients.

    Time frame: From enrollment until 4 weeks after the end of treatment

  3. Quality of Life (lung cancer specific)

    The European organization for the Research and Treatment of Cancer Questionnaire - lung cancer module (EORTC QLQ-LC13) is a clinically valid and useful tool for assessing quality of life, specifically for lung cancer patients.

    Time frame: From enrollment until 4 weeks after the end of treatment

  4. Symptoms of stress, anxiety and depression

    The Depression Anxiety Stress Scales-21 (DASS-21) has been developed as a single screening tool to measure comorbid depression, anxiety, and stress disorders in healthy individuals and represent a psychometrically viable option for health systems and clinicians when assessing distress in cancer patients.

    Time frame: From enrollment until 4 weeks after the end of treatment

  5. Sleep quality

    The Pittsburgh Sleep Quality Index (PSQI) is a valid and reliable tool to assess sleep quality across diverse populations. Total scores range from 0 - 20, with a score of 5 or more indicating a poor sleep quality.

    Time frame: From enrollment until 4 weeks after the end of treatment

  6. Quadriceps strength

    A hand-held dynamometer (Microfet, Biometrics, NL) will be used to assess right isometric quadriceps strength. Patients will be tested while sitting in an upright position. The make test, as described by the ERS/ATS guidelines, will be performed. The best of at least three reproducible measurements (\<10% variability) will be used for analyses.

    Time frame: From enrollment until 4 weeks after treatment

  7. Functional exercise capacity

    Functional exercise capacity will be measured by a 1-min sit-to-stand (1MSTS) test and is a reliable and valid test for measuring functional exercise capacity in COPD patients. Each participant will perform the test twice, with the highest value used for subsequent analyses. Before and after the test, dyspnoea and fatigue will be monitored using the BORG-scale. The heart rate and SpO2 will be monitored continuously throughout the test.

    Time frame: From enrollment until 4 weeks after treatment

  8. Frailty

    Frailty will be assessed according to the criteria of Fried et al. The frailty phenotype is identified by the presence of three or more of the following components. Unintentional weight loss, exhaustion, low activity, slowness and weakness. Cut-off values for slowness and weakness were defined according to the European Working Group on Sarcopenia in Older People 2 (EWGSOP2) recommendations.

    Time frame: From enrollment until 4 weeks after the end of treatment

  9. Volume of physical activity

    Patients will be asked to wear a wearable (Garmin Vivosmart 5) throughout the whole study period as a measure of total volume of PA. Whereas wearables will not provide a valid outcome to be used as primary outcome, the data are valid to provide an overall measure of physical activity.

    Time frame: From enrollment until 4 weeks after the end of treatment

  10. Digital Mobility Outcomes (DMOs)

    The DMOs, more specifically, gait pace, gait rhythm and gait bout-to-bout variability will be measured using the Dynaport Movemonitor +. This outcome measure is part of the PA measurement and therefore requires no additional measurement.

    Time frame: From enrollment until 4 weeks after the end of treatment

  11. Sleep time

    Sleep time will be measured using the Actigraph GT3X, worn on the non-dominant wrist during the night.

    Time frame: From enrollment until 4 weeks after the end of treatment

Other outcomes

  1. Occurence of (re)hospitalization, all-cause mortality and cancer-related mortality

    The occurrence of (re)hospitalization, all-cause mortality and cancer-related mortality in the year after the start of the study will be reported.

    Time frame: From enrollment until 1 year after the start of the study

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 17, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
