high intensity aerobic exercise training and immune cell mobilization in patients with lung cancer (hi aim)

Conditions: Cancer; Cancer of Lung

Summary: the purpose of this study is to investigate if high-intensive training can mobilize and activate the immune system, and thereby enhance the effect of the conventional treatment of lung cancer patients. an important aspect of this study will investigate if the presence of various proteins and cells in blood and tumor biopsies can verify or predict the effect of the high-intensive training. in this clinical trial, patients with lung cancer will combine their conventional therapy with a six-week exercise program.

research has shown that exercise training has several beneficial effects in cancer patients and survivors both during and after anti-cancer treatment, including improved physical function, reduction of symptoms, reduction of side effects and improved quality of life (qol). in addition, a physical active lifestyle is associated with reduced risk of some cancers. recent data in mouse models have shown that tumor-bearing mice randomized to a voluntary wheel running group showed over 60% reduction in tumor incidence and progression in several tumor models. moreover, the mouse data clearly showed homing of t and natural killer (nk) cells to tumors in an exercise dependent manner, underscoring that exercise may render patients more prone to respond to therapy. however, most of the underlying biological mechanisms leading to the documented beneficial effects of physical exercise in relation to cancer are yet unknown, but exercise-mediated changes in hormone levels, inflammation and immune cell function are thought to play a key role. included participants will be randomized 1:1 to an intervention group and a control group. participants in the intervention group will receive a six-weeks exercise-based intervention with supervised and group-based exercise training three times a week at the hospital setting. each training session will consist of intermediate and high intensity interval training. the exercise-based intervention will be combined with standard oncological treatments; checkpoint inhibitors, checkpoint inhibitors combined with chemotherapy or oncological surveillance. participants in the control group will still receive standard oncological treatments; immune checkpoint inhibitors, checkpoint inhibitors combined with chemotherapy or oncological surveillance.

Eligibility criteria:
inclusion criteria: * metastatic non-small cell lung cancer * measurable disease according to recist 1.1 * age ≥ 18 years * treatment with immune checkpoint inhibitors, checkpoint inhibitors combined with chemotherapy or oncological surveillance * eastern cooperative oncology group (ecog) performance status score (ps) ≤2 * preferably metastasis suitable for biopsy * normal marrow function as defined below: * white blood cell count (wbc) ≥ 2 x 10⁹/l * absolute neutrophil count (anc) ≥ 1.5 x 10⁹/l * hemoglobin ≥ 6.0 mmol/l * platelet count ≥ 100 x 10⁹/l * in case, a patient's bone marrow values fall slightly below the described values, the treatment responsible doctor will be consulted. the general health and the ability to proceed with the treatment will be considered. * ability to speak and read danish * willingness to give informed consent for participation in the study exclusion criteria: * any physical condition that hinder the execution of physical exercise, as assessed by the referring oncologist and by a physiotherapist * severe dyspnea that hinder the execution of high intensity aerobic exercise training, as assessed by the referring oncologist * symptomatic brain metastases * dementia, psychotic disorders, or other cognitive diseases or conditions that hinder participation in a clinical exercise-based trial, as assessed by the referring oncologist * unstable medical disease or history of serious or concurrent illness; any medical condition that might be aggravated by exercise training or that cannot be controlled, including, but not restricted to congestive heart failure (nyha class iii-iv), unstable angina pectoris, implantable cardioverter defibrillator (icd), or myocardial infarction within 6 months * a condition requiring systemic treatment with either corticosteroids (\> 10 mg daily prednisone equivalents) or other immunosuppressive medications. inhaled or topical steroids and adrenal replacement doses ≤ 10 mg daily prednisone equivalents are permitted * use of beta blockers * any systemic infections within the last 4 weeks * patients who receives chemotherapy as monotherapy * in patients with documented bone metastases; patients with: * a bone metastatic burden or location that poses a risk of injury in the performance of exercise training, as assessed by the referring oncologist
