Abstract:
Immune-checkpoint inhibitors (ICI), although revolutionary in improving long-term survival outcomes, are mostly effective in patients with immune-responsive tumors. Most patients with cancer either do not respond to ICIs at all or experience disease progression after an initial period of response. Treatment resistance to ICIs remains a major challenge and defines the biggest unmet medical need in oncology worldwide. In a collaborative workshop, thought leaders from academic, biopharma, and nonprofit sectors convened to outline a resistance framework to support and guide future immune-resistance research. Here, we explore the initial part of our effort by collating seminal discoveries through the lens of known biological processes. We highlight eight biological processes and refer to them as immune resistance nodes. We examine the seminal discoveries that define each immune resistance node and pose critical questions, which, if answered, would greatly expand our notion of immune resistance. Ultimately, the expansion and application of this work calls for the integration of multiomic high-dimensional analyses from patient-level data to produce a map of resistance phenotypes that can be utilized to guide effective drug development and improved patient outcomes.
Insights
Immune-checkpoint inhibitors (ICIs) show limited efficacy in many cancers. This research outlines a framework of eight biological processes, or "immune resistance nodes," to guide future research and improve patient outcomes.
Area of Science:
- Oncology
- Immunology
- Cancer Research
Background:
- Immune-checkpoint inhibitors (ICIs) have transformed cancer treatment but are ineffective for many patients.
- Resistance to ICIs is a significant challenge, limiting their widespread clinical benefit.
- Identifying mechanisms of resistance is crucial for developing more effective cancer therapies.
Purpose of the Study:
- To establish a framework for understanding and researching immune resistance to ICIs.
- To identify key biological processes contributing to ICI resistance.
- To guide future research directions and drug development for overcoming treatment resistance.
Main Methods:
- A collaborative workshop involving experts from academia, biopharma, and nonprofit sectors.
- Collating seminal discoveries related to known biological processes.
- Defining eight "immune resistance nodes" based on biological processes.
Main Results:
- Identified eight critical biological processes as "immune resistance nodes."
- Highlighted seminal discoveries defining each node.
- Posed critical research questions to advance the understanding of immune resistance.
Conclusions:
- A structured framework for immune resistance research has been proposed.
- Answering key questions about these nodes will expand our understanding of ICI resistance.
- Integrating multiomic data can create a map of resistance phenotypes to guide drug development and improve patient outcomes.
