Checkpoint Inhibitor-related PneumonitisNCT07340892
Diagnostic Biomarkers for Checkpoint Inhibitor-related Pneumonitis
An observational study of Checkpoint Inhibitor-related Pneumonitis, run by Zhou Chengzhi at 1 site in China.
Trial summary
Checkpoint inhibitor-related pneumonitis (CIP) is a common fatal immune-related adverse events of PD-1/PD-L1 inhibitors. Early diagnosis of CIP is crucial for timely intervention and improved prognosis; however, the absence of precise and effective diagnostic techniques often leads to underdiagnosis and misdiagnosis.

About this study
Official title: Prospective Study of NMR-based Serum Metabolic Profiles for the Diagnosis of Checkpoint Inhibitor-related Pneumonitis
Checkpoint inhibitor-related pneumonitis (CIP) is a common fatal immune-related adverse events of PD-1/PD-L1 inhibitors. Early diagnosis of CIP is crucial for timely intervention and improved prognosis; however, the absence of precise and effective diagnostic techniques often leads to underdiagnosis and misdiagnosis. The investigators conducted a prospective clinical study to evaluate the effectiveness of ¹H-nuclear magnetic resonance (NMR)-based lipoprotein and metabolite analysis in diagnosing checkpoint inhibitor-related pneumonitis (CIP), aiming to improve its early diagnosis rate.
Read the detailed description
Checkpoint inhibitor-related pneumonitis (CIP) is a common and potentially fatal immune-related adverse event associated with PD-1/PD-L1 inhibitor therapy. The early and accurate diagnosis of CIP is crucial for timely intervention and improving patient prognosis. However, in clinical practice, the overlapping clinical presentations and imaging features of CIP with infectious pneumonia, tumor progression, or other pulmonary diseases pose a significant diagnostic challenge. The current lack of precise and specific diagnostic techniques often leads to underdiagnosis or misdiagnosis. This diagnostic dilemma can delay the optimal treatment window and may result in the unnecessary interruption or discontinuation of effective immunotherapy, ultimately compromising overall anti-tumor efficacy.
Metabolomics, the comprehensive analysis of small-molecule metabolites, provides a dynamic readout of an organism's physiological state and has shown great promise in biomarker discovery for various diseases. Serum, in particular, offers an easily accessible biofluid that reflects systemic metabolic alterations. ¹H-Nuclear Magnetic Resonance (¹H-NMR) spectroscopy is a robust, reproducible, and quantitative platform ideal for profiling key serum components, including lipoproteins and a wide range of low-molecular-weight metabolites, in a high-throughput manner. The investigators hypothesize that the development of CIP induces a distinct, detectable alteration in the host's systemic metabolic profile, which can be captured by NMR analysis and serve as a diagnostic signature.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Experimental group | Checkpoint inhibitor-related pneumonitis | |
| Control group | Lung cancer patients who received immunotherapy but did not develop CIP |
What is being measured
The primary outcome is the main question the study is designed to answer.
Diagnostic performance
The Area Under the Receiver Operating Characteristic Curve (AUROC) of a classifier model derived from NMR serum metabolic profiles to distinguish between patients with confirmed checkpoint inhibitor-related pneumonitis and control patients on immunotherapy without pneumonitis.
Measured: Blood sampling for testing within 1 day after enrollment.
