Analyzing Resistance and Toxicity in Cancer Treatments

POSITive: Prospective Observational Study for the Multidimensional Analyses of Resistance and Toxicity to Immune- and Targeted-therapies

Observational European Institute of Oncology · NCT06321640

This study is trying to understand why some cancer treatments don't work for everyone and what side effects they cause, so that doctors can better tailor treatments for patients with different types of cancer.

What this trial studies

This observational study focuses on understanding the resistance mechanisms and toxicities associated with targeted therapies and immune checkpoint inhibitors in various cancers, including breast cancer, lung cancer, melanoma, head and neck cancer, and urothelial carcinoma. It aims to identify biomarkers that can predict patient responses and adverse effects to these treatments, which are crucial for optimizing therapeutic strategies. The study involves multiple cohorts based on disease stage, from operable to metastatic conditions, and requires participants to undergo diagnostic biopsies. By exploring the molecular mechanisms of resistance and toxicity, the study seeks to improve treatment outcomes for cancer patients.

Who should consider this trial

Good fit: Ideal candidates for this study are adults over 18 years old with a histological diagnosis of any cancer who meet specific cohort criteria.

Not a fit: Patients with a performance status greater than 2 or a life expectancy of less than 3 months may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more personalized and effective cancer treatments by identifying which therapies are best suited for individual patients based on their unique biomarkers.

How similar studies have performed: Other studies have shown promise in identifying biomarkers for targeted therapies, but this study's comprehensive approach to resistance and toxicity is relatively novel.
