Systematic evaluation of immune regulation and modulation.

Area of Science:

• Oncology
• Immunology
• Biomarker Discovery

Background:

• Cancer immunotherapies demonstrate significant clinical efficacy across various cancers.
• Monitoring immune and tumor responses is crucial for advancing immunotherapy.
• Identifying predictive and prognostic biomarkers is key to optimizing these treatments.

Purpose of the Study:

• To establish systematic approaches for monitoring immune responses to cancer immunotherapies.
• To provide recommendations for sample collection and assay methods for immune biomarkers.
• To guide the interpretation of data from immunotherapy monitoring assays.

Main Methods:

• Convening a multidisciplinary expert task force (Working Group 3) from the Society for Immunotherapy of Cancer.
• Reviewing and recommending systematic assessment of immune regulation and modulation.
• Using tumor microenvironment, microbiome, bone marrow, and T cells as examples for sample collection and analysis.

Main Results:

• Discussion on optimal timing and types of sample collection for various biological sources.
• Outline of potential measurements, assays, and analyses for immune biomarker evaluation.
• Emphasis on unique requirements for sample collection and high-throughput assays.

Conclusions:

• Systematic monitoring of immune responses and biomarkers is critical for advancing cancer immunotherapy.
• Standardized approaches to sample collection and assay methodologies are needed.
• These recommendations aim to improve the interpretation and utility of immunotherapy monitoring data.
