Combining EXL01 with Nivolumab for Advanced Lung Cancer

EXL01 in Combination With Nivolumab for Advanced NSCLC Refractory to Immunotherapy

PHASE1; PHASE2 · University Hospital, Lille · NCT06448572

This study is testing if combining a gut bacteria treatment with an immunotherapy drug can help people with advanced lung cancer who haven't had success with other treatments.

What this trial studies

This trial investigates the combination of EXL01, a single-strain bacterium from the healthy gut microbiota, with nivolumab, an immunotherapy drug, for patients with advanced non-small cell lung cancer (NSCLC) who have not responded to standard treatments. It is a pilot Phase I/II, one-arm, monocentric study aimed at evaluating the safety and efficacy of this combination therapy. The study targets patients who have progressed after receiving anti-PD-(L)1 agents and platinum-based chemotherapy, focusing on those with limited treatment options. The goal is to assess whether this novel combination can provide clinical benefit in a challenging patient population.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with inoperable advanced or metastatic NSCLC who have previously received anti-PD(L)1 therapy and platinum-based chemotherapy.

Not a fit: Patients with specific oncogene alterations such as EGFR, ALK, ROS1, MET, HER2, or RET mutations may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could offer a new treatment option for patients with advanced NSCLC who have exhausted standard therapies.

How similar studies have performed: While the combination of immunotherapy and microbiota modulation is a novel approach, similar studies have shown promise in enhancing the efficacy of cancer treatments.
