IMMUNO-FIT Observational Study

The Immuno-FIT Observational Study: A Phase II Window Observational Study Investigating the Effects of Immunotherapy on Cardiopulmonary Fitness, Quality of Life, and Treatment Outcomes in Patients With Advanced Cancer

Source: ClinicalTrials.gov · Last updated 28 Apr 2026

Brief summary (registry, in English)

This observational study will investigate how immunotherapy affects physical fitness, quality of life, and treatment tolerance in adults with solid cancers. Immunotherapy can cause a range of side effects that impact daily functioning and may lead to treatment delays or early discontinuation. Physical fitness may influence how well patients cope with treatment, yet little is known about how fitness changes during immunotherapy or whether baseline fitness is linked to outcomes. Participants will complete fitness testing using cardiopulmonary exercise testing (CPET) and quality-of-life questionnaires before starting immunotherapy and again 12 weeks later. Blood samples will also be taken, and long-term outcomes including survival, disease progression, and quality of life will be followed for up to 24 months. All cancer treatment will remain standard of care. A small number of participants will be invited to take part in an optional research biopsy at week 12 to explore how physical fitness relates to changes in the tumour's immune environment. The study will help researchers understand natural changes in fitness during immunotherapy, identify whether baseline fitness is associated with treatment tolerance or outcomes, and generate information needed to design future trials testing exercise-based interventions during immunotherapy.

Who cannot take part

Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.

Prior treatment

  • Prior systemic anti-cancer immunotherapy for unresectable or metastatic disease, EXCEPT:
  • Prior adjuvant or neoadjuvant immunotherapy if all treatment-related adverse events have returned to baseline or stabilized
  • Prior anti-PD-1, anti-PD-L1, or anti-CTLA-4 therapy with at least 6 months since last dose and date of disease recurrence

Other illness

  • Acute myocardial infarction within 6 weeks
  • Unstable angina
  • Uncontrolled cardiac arrhythmias causing symptoms or hemodynamic compromise
  • Uncontrolled heart failure
  • Acute systemic infection
  • Inability to perform cardiopulmonary exercise testing (e.g., severe lower limb dysfunction, severe peripheral vascular disease)
  • Severe cardiopulmonary disease precluding safe sedation (for endoscopic biopsies)
  • Suspected bowel obstruction or perforation (for gastrointestinal biopsies)
  • Severe portal hypertension with high-risk varices (for upper endoscopy)

Lab values

  • Uncorrectable severe coagulopathy (INR \>1.5, platelet count \<50,000/µL)

Age

  • Age \<18 years

Other
