Summary:
The aim of this study is to evaluate the effect of a probiotic supplement containing
Bifidobacterium animalis lactis BL-04 on the clinical effectiveness of immunotherapy in
patients diagnosed with metastatic non-small cell lung cancer who are receiving
immunotherapy.
Detailed description:
Despite modern treatments, lung cancer remains a leading cause of high mortality
worldwide. Over the past decade, significant improvements in patient survival have been
achieved with immune checkpoint inhibitors, which enhance the T cell-mediated immune
response to eradicate cancer cells. However, therapeutic resistance, drug side effects,
and heterogeneous treatment responses limit their effectiveness. Recent studies have
established a clear relationship between gut microbiota and cancer immunotherapy. The
intestinal microbiota has been shown to stimulate the anti-tumor immune response by
modulating immune system cells. Evidence from preclinical and clinical studies indicates
that gut microbiota plays a crucial role in the efficacy of immunotherapy and the
modulation of drug toxicity. Identifying the microbiota as a potential biomarker could
facilitate personalized treatment protocols. Genetic, epigenetic, and microbiota
modulation factors are essential for optimizing cancer immunotherapy outcomes.
Consequently, research is increasingly focusing on personalized treatment protocols for
microbiota modulation, including diet regulation, fecal microbiota transfer, prebiotics,
and probiotics. There has been a significant rise in studies demonstrating the clinical
benefits of microbial therapy products as complementary treatments.
The functional role of microbiota in modulating the systemic immune response has prompted
investigations into its impact on cancer immunotherapy, particularly with agents
targeting immunological checkpoints like PD-1. Recent studies have identified both
positive and negative regulatory bacteria that influence immunotherapy effectiveness.
However, sociocultural and dietary lifestyle differences affect gut microbiota
composition, leading to variations between populations. Therefore, studies are needed to
identify the unique microbiome composition of each population to develop microbiota
biological indicators for cancer immunotherapy. No research has been conducted in this
area in Türkiye. This study aims to identify bacterial species that may serve as
biomarkers for the microbiota specific to Turkish cancer patients receiving immunotherapy
and use them for prognostic purposes.
Understanding the significant role of probiotics in modulating intestinal microbiota has
increased the demand for these food supplements. Studies show that anti-tumor efficacy is
specific to the bacterial strain. For instance, Bifidobacteriums have been reported to
enhance the effectiveness of PD-1 blockers in experimental rat models. In another study,
B. lactis BL-04 reduced immunotherapy-induced colitis in animals.
This study will investigate the effect of a probiotic supplement containing
Bifidobacterium animalis lactis BL-04 on clinical objective response, clinical benefit
rates, and intestinal microbiota in patients with metastatic non-small cell lung cancer
(mNSCLC) receiving nivolumab. The results may facilitate the development of specific
probiotic supplements as a complementary therapy for mNSCLC treatment.
