Understanding how genetic mutations affect cancer treatment response in advanced solid tumours

Official title: Understanding the Molecular Pathways Underlying Drug Response and Resistance in Early Clinical Trials Through Tumour Molecular Characterisation

Run by Institute of Cancer Research, United Kingdom · NCT07737509 · Data updated 2026-11-12

This study tests whether mutations found in tumor and blood samples can help predict who will benefit from early-phase cancer treatments.

Is this trial a fit for you?

Likely a good fit

Adults (18+) with an advanced solid tumour who are being considered for or are participating in an early-phase clinical trial.

Probably not a fit

Patients whose tumours do not show actionable mutations or whose mutations do not predict response may not see a direct benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is an observational study enrolling adults with advanced solid cancers who are either being considered for or are already in early-phase clinical trials. Researchers will analyze existing tumor tissue and blood samples to identify genetic mutations and how these mutations change over time. The goal is to see if specific mutations correlate with responses or resistance to therapies, aiding better matching to trials and personalized treatment options.

Why it matters

Potential benefit: If successful, results could improve how patients are matched to trials and personalize treatment choices based on tumor genetics.

How similar studies have gone: Previous work in tumor molecular characterization has shown promise in guiding trial matching and understanding drug response, though this exact approach in early-phase trials is still evolving.
