Blood levels of immune checkpoint antibodies and their links to inflammation, cachexia, and response in lung cancer

Inflammation, Cachexia and Therapeutic Response in Lung Cancer Treated With Immune Checkpoint Inhibitors: Exploratory Observational Study

Observational University Hospital, Tours · NCT07004868

Test whether blood concentrations and how the body handles immune checkpoint antibodies relate to inflammation, weight loss (cachexia), and treatment response in adults with lung cancer starting immunotherapy.

What this trial studies

This is a single-center, observational project measuring blood concentrations and pharmacokinetics of various immune checkpoint inhibitor antibodies in adults with lung cancer at first administration. Investigators will collect clinical data on weight change, inflammatory markers, and treatment outcomes without changing prescribed therapy. The study will analyze relationships between antibody exposure, signs of cachexia or systemic inflammation, and subsequent clinical response or toxicity. All participants must be followed at the University Hospital (CHRU) of Tours and consent to data use.

Who should consider this trial

Good fit: Adults (≥18 years) with any histology or stage of lung cancer who are receiving their first immune checkpoint inhibitor dose and are followed at CHRU de Tours.

Not a fit: Patients already receiving ICIs before enrollment, those not followed at CHRU de Tours, or those who refuse data processing are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, the findings could help tailor immunotherapy dosing and identify patients more likely to respond or to develop cachexia-related complications.

How similar studies have performed: Previous work has shown links between immune checkpoint inhibitor exposure and outcomes, but integrating detailed pharmacokinetics with inflammation and cachexia measures in lung cancer is relatively novel.
