Predicting durvalumab toxicity using microbiome analysis in lung cancer patients

Using Microbiome to Predict Durvalumab Toxicity in Post-CCRT NSCLC Patients (Microdurva)

Observational University of Kansas Medical Center · NCT04680377

This study is testing if the bacteria in the gut can help predict how bad the side effects will be for lung cancer patients taking durvalumab after their treatment.

What this trial studies

This observational study aims to investigate whether the microbiome can be used to predict the toxicity of durvalumab in patients with stage III non-small cell lung cancer (NSCLC) who have undergone concurrent chemoradiation therapy. Participants will be monitored for treatment-related side effects while their microbiome composition is analyzed. The study seeks to establish a correlation between microbiome profiles and the severity of toxicity experienced during treatment. By understanding these relationships, the study hopes to improve patient management and treatment outcomes.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with locally advanced, unresectable stage III NSCLC who have completed specific prior chemotherapy and radiation therapy.

Not a fit: Patients with early-stage NSCLC or those who have not received the required prior treatments may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to personalized treatment plans that minimize toxicity for lung cancer patients receiving durvalumab.

How similar studies have performed: While the use of microbiome analysis in predicting treatment outcomes is an emerging field, this specific approach to durvalumab toxicity prediction is novel and has not been extensively tested in prior studies.

Exclusion Criteria:

* Concurrent enrollment in another clinical study, unless it is an observational (non-interventional) clinical study or if the participant is in the follow-up period of an interventional study
* Participation in another clinical study with an investigational product during the last 4 weeks prior to enrollment on this study
* Prior randomization or treatment in a previous durvalumab clinical study regardless of treatment arm assignment

* Participants who have progressed following definitive, platinum-based, concurrent chemoradiation therapy
* Known allergy or hypersensitivity to durvalumab or any of durvalumab's excipients
* Psychiatric illness/social situations that would limit compliance with study requirements or compromise the ability of the patient to give written informed consent
