SITC Election Platform Statement

What are the two or three critical issues facing the field of cancer immunotherapy?

Immunotherapy has dramatically changed cancer treatment and established new standards of care for several tumor types. For example, within the span of just a few years, we have seen regulatory approvals for neoadjuvant, adjuvant, and perioperative immunotherapy treatments for patients with early-stage, resectable non-small cell lung cancer. Unfortunately, however, these studies also indicate that many patients fail to respond to immunotherapy for reasons that are incompletely understood. One of the critical challenges we are facing in clinical practice is the inability to deliver personalized treatments for some subsets of patients due to the lack of robust biomarkers of therapeutic efficacy. One way our group and others are tackling this issue is by integrating multiomics analyses of longitudinal samples with preclinical studies using human-relevant models and drawing on expertise from multiple fields. This approach will enable a comprehensive framework for precision cancer immunotherapy that will consider tumor, immune-related and patient factors and lead to the discovery of reliable biomarkers for patient stratification and therapy selection. We expect that this strategy will enhance clinical outcomes for a greater number of patients while minimizing treatment-related toxicities.

A second important gap that is hindering our ability to effectively deliver cancer immunotherapy for a potential cure is our incomplete understanding of how to optimally combine or sequence immune-based treatments which have distinct mechanisms of action (e.g., checkpoint inhibitors, T-cell engagers, vaccines, bispecific antibodies) with other therapeutic modalities, such as surgery, chemotherapy and radiotherapy. An improved understanding of how to sequence various immune agents in a personalized fashion will provide an opportunity to de-escalate treatments and minimize both clinical and financial toxicity. Conversely, this strategy will also enable us to tailor intensified therapeutic regimens using innovative immunotherapies for individuals who are at considerable risk of disease relapse. This more rational approach to cancer immunotherapy holds the potential to significantly impact healthcare outcomes and alleviate burden from patients and their support system.

A third issue hampering progress in cancer immunotherapy is that many individuals with cancer may have limited access to clinical trials evaluating promising immunotherapy treatments and combination strategies. To promote equitable access to novel agents and advance clinical and translational research, we must streamline clinical trials while scaling clinical operations to a more sustainable level. By doing so, we can reach a broader population of cancer patients that better reflects the real-world clinical practice and expand patient access to potentially more effective treatments. The clinical and translational data generated from more comprehensive and diverse populations and cohorts should stimulate new scientific hypotheses and foster innovative grant opportunities.

What is Your Vision for SITC?

My contributions as member of the SITC Board of Directors will be centered on implementing initiatives that foster translational research and multidisciplinary collaborations in order to bridge the void between basic science discoveries and clinical applications. A fully integrated interdisciplinary approach that expands our understanding of how tumor biology influences the immune system is critical to maximize the effectiveness of immune-based therapies in cancer patients, develop novel therapeutic strategies that can enhance outcomes for a greater number of individuals and lead to a cure. By facilitating strategic partnerships between academic and community practice investigators, industry sponsors, regulatory authorities and patient advocacy, SITC will be ideally positioned to accelerate the pace of scientific discovery and clinical development, ultimately expediting the delivery of innovative therapies to patients at a global scale.

I will help position SITC as the leading platform for presenting transformative, practice-changing immunotherapy results from clinical trials. This will generate greater participation from clinicians, healthcare providers from academia and community setting, physician-scientists, sponsors and regulators. As a result, SITC will move to the forefront of the field as an international hub for sharing the latest findings that could support novel immunotherapy drug approval. The annual conference will benefit from a more robust exchange of ideas across specialties and expertise that may result in expedited strategic collaborations. This strategy will also shape the scientific impact and reach of the journal’s organization as a potential platform for the dissemination of the presented findings.

I will also work with SITC board members to develop high-risk, high-reward funding mechanisms that support potentially transformative research. I envision that these opportunities would be team science awards for creative investigators from across different scientific disciplines spanning basic science, translational and clinical research who propose groundbreaking investigations that address key questions in the field. This investment will accelerate discovery, promote the procurement of robust data for moving promising compounds into clinical testing, and foster the career development and professional growth of each stakeholder across diverse career stages, paths and disciplines.

SITC Election Platform Statement

What are the two or three critical issues facing the field of cancer immunotherapy?

The field of cancer immunotherapy has grown exponentially over the last two decades, having an unprecedented impact on patients and expanding our knowledge of the interplay between immune surveillance and cancer biology, which has subsequently translated to the rapid advancement of the field. However, despite the extraordinary impact of checkpoint inhibitors, cell therapies, immunomodulatory agents, and cancer vaccines, there remain several critical issues facing the field of immunotherapy which must be addressed to maximize the potential impact of immunotherapies:

  • Expanding Treatable Populations: Despite the many patients who have benefitted from cancer immunotherapies, there are still several limitations to maximizing and expanding the treatable population. Although there are several biological unknowns that have limited the impact of immunotherapies in certain cancers, we may have a dramatic impact on expanding access by improving education and awareness of patients and physicians, incorporating novel manufacturing and delivery technologies to reduce cost-of-goods, improve scale, and reduce patient burden, and leveraging our current understanding of the mechanism of action of immunotherapies to pivot to novel disease indications. Continued partnership with community physicians to strengthen referral networks into academic clinical trials, novel technologies such as iPSC derived allogeneic and nanoparticle-based delivery systems, and expansion of cellular therapies and T-cell engager technologies outside of oncology indications into a broad range of autoimmune, rheumatologic and neuroinflammatory disease will have an enormous impact and dramatically expand the reach that these therapies may have for patients with high unmet need.
  • Adoption of Novel Technologies: since the approval of the first checkpoint inhibitor in 2011, there have been hundreds of investigational immunotherapies tested in clinical trials, with over 15 approvals for a wide range of cancers. From the first generation of clinical trials, we have learned an immense amount about the limitations of immunotherapies, such as clinical correlates of response, mechanisms of resistance, and immune-related adverse events. These learnings have led to the advent of novel technologies. However, to maximize medical advancement of the next generation of immunotherapies, we must accelerate the rate at which we translate and test these technologies in the clinical setting. Clinical trials investigating novel tumor microenvironment modulation approaches to overcome the immunosuppressive TME and enhance efficacy, incorporation of optimized immunotherapy combination approaches to enhance risk-benefit, uptake of innovative manufacturing platforms to reduce the cost and burden to the patient while improving the scale at which we can manufacture cellular therapies, and design of next-generation synthetic biology technologies to improve potency and persistence of cellular therapies are a few key examples of existing technologies which must be efficiently investigated in the clinic to continue to expand the field.
  • Accelerating Access: The development of an immunotherapy into an available medicine typically takes from 10 to 15 years. Although this timeline can vary depending on several factors, including the complexity of the therapy, the specific type of cancer being targeted, and the regulatory environment, it is critical for academia, biotechnology, pharma, and regulatory agencies to work closely together to accelerate development timelines so that better medicines are available to patients in need sooner. Implementation of innovative trial designs such as adaptive trial designs, master protocols and real-world evidence, utilization of novel regulatory paths such as accelerated approval pathways and rolling submissions, and increasing collaborative efforts with public-private partnerships, consortia and networks will improve the speed by which we acquire clinical data and translate directly into access to life-saving immunotherapies for patients in critical need.

What is Your Vision for SITC?

SITC has been a leader in bringing together academic clinical researchers and scientists, regulatory agencies, and industry, to overcome scientific hurdles that are beyond the capacity of any single entity. It is critical that SITC continue to lead collaborative efforts to accelerate the sharing of information, translation of science into the clinic, and speed at which novel therapies are approved to enhance access of therapies to as many patients with unmet need as possible.

Over the last decade, immunotherapies have positively impacted the lives of hundreds of thousands of cancer patients, however the addressable population is far greater than the patients who have been reached thus far. As transformative efficacy data have emerged with immunotherapies in disease indications outside of oncology, including a broad range of autoimmune, rheumatologic and neuroinflammatory diseases, SITC has the unique opportunity to lead further expansion and impact of key immunotherapies, such as cellular therapies and T-cell engagers, outside of oncology. As the largest organization dedicated to immunotherapy of cancer, the depth and breadth of knowledge that the Society holds from its decades of experience will accelerate advancement of immunotherapies to a large segment of patients with autoimmune diseases with high unmet need and has the potential to lead to a paradigm changing shift in treatment.

It has been my privilege to be a committed member of SITC since I joined the Society. I have served on the SITC Early Career Scientist Committee since 2019 when I was first elected and participated as invited faculty at the SITC Sparkathon mentorship program (2023, 2024), SITC Women in Cancer Immunotherapy Network (2021, 2023, 2025), and SITC Annual Meeting (2025). In addition to my commitment to SITC, I actively engage in the community, disseminating knowledge about cellular therapies and their potential impact in a broad range of severe and incurable autoimmune diseases. I have given public outreach presentations for several organizations, including the Lupus Clinical Investigators Network, the Lupus Research Alliance, and the Rheumatology Nursing Society and remain closely engaged with several patient advocacy groups. I have participated as an invited contributor in the Lupus Accelerating Breakthroughs Consortium (ABC) and Lupus ABC CAR T Working group, a first-of-its-kind public-private partnership bringing people with lupus together in collaboration with the FDA, industry, academic clinical researchers and scientists to overcome scientific hurdles that are beyond the capacity of any single entity and to advance the development of urgently needed treatments for lupus. As an elected SITC At-Large Director, I would be passionate about expanding access, within and beyond oncology, to cutting edge medications through acceleration of science, drug development and community education.

SITC Election Platform Statement

What are the two or three critical issues facing the field of cancer immunotherapy?

First, my clinical and translational research have showed me that we can overcome resistance mechanisms to immunotherapies and improve patient outcomes if we provide a good therapeutic combination to the right patients. Therefore, I believe there is a crucial need to advance biomarker-driven and personalized oncology, but also take into account critical clinical parameters (e.g liver metastasis, high LDH) to better stratify patient care. I have long advocated for a paradigm shift from histology-based to biomarker-driven approaches, emphasizing that tumor biology is paramount in determining the efficacy of immunotherapies. Finally, yet importantly, with the increasing use of immunotherapies, especially in earlier disease settings, avoiding or managing immune-related adverse events (irAEs) effectively is becoming increasingly important and I believe there is still much to be done for proper education of caregivers and doctors in that endeavor.

What is Your Vision for SITC?

My vision for SITC is one where the society continues to be the preeminent global leader in advancing the science and application of cancer immunotherapy. Building upon SITC's instrumental role over the past years in the rapid adoption of immunotherapies, I believe SITC must now expand its global leadership in immuno-oncology education. As immunotherapies become more widespread, and the science behind it is advancing at a fast pace, our educational efforts must keep up to ensure optimal patient care. I strongly believe SITC should continue to champion biomarker-driven and personalized approaches to immunotherapy, fostering research and clinical trials that are guided by the biological characteristics of individual cancers rather than solely by their histology.

My contributions to SITC over the past 15 years as an active member include contributing to educational content (symposia, webinars,…), being in the organizing committee and presenting clinical trial results at SITC Annual Meetings or publishing SITC guidelines for immunotherapy practice. I have consistently advocated for SITC's role in education and research in immuno-oncology and have been a vocal thought leader, calling for biomarker-driven treatment strategies and enhanced global education initiatives. My previous candidacy in the 2023 SITC election further demonstrates my commitment to the society.

My leadership roles in the European immuno-oncology community as a leader at the ESMO Immuno-Oncology (IO) Congress and as co-founder and vice-president of the French Society for Cancer Immunotherapy (FITC) could bring an opportunity to bridge transatlantic expertise between the US and Europe, and build collaborative networks and educational platforms. I believe we can foster enhanced global scientific exchange, promoting best practices, and harmonizing educational content across continents. I have advocated for SITC to consider reviving initiatives like the World Immunotherapy Council (WIC) to coordinate efforts across societies and continents, facilitate joint educational programs, cross-promotion of clinical trials and consensus guidelines.

By leveraging my experience and leadership in international immuno-oncology communities, I want to significantly contribute to SITC's mission and help forge even stronger ties between continents to conquer cancer through immunotherapy.

Biography

Robert D. Schreiber, PhD is the Andrew M. and Jane M. Bursky Distinguished Professor of Pathology and Immunology at Washington University School of Medicine in St. Louis, founding director of the Bursky Center for Human Immunology and Immunotherapy and co-leader of the Tumor Immunology Program of the Washington University Siteman Comprehensive Cancer Center. Schreiber is a cytokine biologist and tumor immunologist who studies naturally- and therapeutically-induced immune responses to cancer. At a time when the field had discounted any role for the immune system in cancer development and control, Schreiber showed conclusively that the immune system is not only capable of preventing cancer outgrowth but also sculpting cancer immunogenicity by a process he called “Cancer Immunoediting.” Based on that work, Schreiber and colleagues went on to show that tumor specific mutant neoantigens are favored targets of cancer immunoediting and of immune checkpoint therapy, and can be used to generate effective therapeutic anti-cancer responses in both mouse models of cancer and in human cancer patients. This work then led to development and proof-of-principle validation of an immunogenomics-based personalized cancer neoantigen vaccine approach that is being used and tested in multiple institutions across the world.

During his career, Schreiber has received many distinguished awards and honors including, among others, the William B. Coley Award for Distinguished Research in Basic and Tumor Immunology from the Cancer Research Institute (CRI); the Charles Rodolphe Brupbacher Prize for Cancer Research; the Balzan Prize; the Lloyd Old Prize from the American Association for Cancer Research (AACR) and CRI; the 2023 Richard V. Smalley Memorial Award from the Society for the Immunotherapy of Cancer (SITC); the 2023 AACR-Princess Takamatsu Memorial Lectureship Award; the 2024 Takeda/New York Academy of Sciences Senior Scientist Innovators in Science Award in Cancer Immunology; and the 2025 Lifetime Achievement Award from the Immunotherapy of Cancer (ITOC) Conference. Schreiber is a Fellow of the Academy of Immuno-Oncology (SITC); The American Association for the Advancement of Science; The American Association for Cancer Research Academy; and The American Association of Immunologists. He is an elected member of the American Academy of Arts and Sciences and the US National Academy of Sciences. 

SITC Election Platform Statement

What are the two or three critical issues facing the field of cancer immunotherapy?

Obviously one of the major issues we now face is how to maintain the momentum of our field in the light of the current environment we are facing involving severe budget reductions/funding hold-ups from the federal government. We need to associate with other scientific organizations and learn how to speak with a single voice about the power and truth of science. We must learn how to become less dependent on government funding and better at attracting funding from the private sector. We need to learn how to do more with less. We need to learn how to speak to the public to better inform them about the great potential of cancer immunotherapy without falling into the use of scientific jargon that they might not understand. Finally, we as scientists are not trained to speak to the public and therefore, we as a society, should be providing courses and/or workshops to teach our young people how best to present their science to non-scientists.

A second critical issue is the need to find a way to more accurately test the large number of therapeutic combinations available to identify those that better predict which will be more efficacious in the clinic. This means developing new preclinical models, including those that rely heavily on artificial intelligence, that will lead to increased success in human cancer patients.

Finally, I am a strong advocate for the continued development of tumor specific vaccines which are beginning to show success in clinical trials. I think the potential to develop off-the-shelf vaccines based on targeting aberrant non-mutated protein expression derived from the dark genome is an exciting possibility that would nicely complement and expand efforts based on methods that focus on generating tumor specific effector T cells. What is needed is evidence that such a vaccine approach will not only be more specific and more effective but also safer than the immunotherapies we have available to us today.

What is Your Vision for SITC?

I envisage that SITC will continue to grow in membership and influence and will be the society that brings together academic, biotech and big pharma scientists and continue to promote productive collaborations between these groups that lead to new practice-changing immunotherapies. I feel that SITC has already made a name for itself as one of the best examples of such a society and I would like to see that reputation continue to grow not only in terms of focus but also in terms of impact.

I next completed my training in Hematology and Oncology from 2006-2009 at Beth Israel Deaconess Medical Center (BIDMC) and, upon graduation in July 2009, was hired as junior faculty at BIDMC and Harvard Medical School (HMS). In 2012, I joined the Mass General Cancer Center and currently serve as the Director of the Center for Melanoma and Director of Translational Research of the Melanoma Program.

I am a clinical and translational investigator whose main areas of interest are the development of novel therapies for malignant melanoma and other solid tumors, targeting both molecular and immune pathways, and the development of clinical biomarkers for these investigational and standard treatment approaches. With deep experience as a clinical investigator, I have led multi-institutional studies, serving as the Principal Investigator (PI) for numerous industry, NIH (CTEP P9466, P9557), and investigator sponsored clinical trials on a national level. My commitment in translational investigation includes leading an expert multi-disciplinary teams including the Cytokine Working Group trial to identify predictive biomarkers for patients with melanoma treated with high-dose IL2; numerous scientific collaborations focused on identification of predictive biomarkers of response to immune checkpoint inhibitors (e.g. anti-PD-1/PD-L1) in patients with advanced melanoma, and the development of blood-based biomarkers that will allow us to better select patients for a given therapy or monitor patients on active therapy. More recently, a key focus of my work has been to identify, predict, and mitigate immune related toxicities associated with immune checkpoint inhibition in cancer patients, an emerging area of investigation that began by describing various types of toxicities, called immune related adverse events (irAEs). I spearheaded efforts and helped establish the Severe Immunotherapy Complications (SIC) Service at MGH in 2017. In recent years, I have served as the Chair of the Society of Immunotherapy in Cancer (SITC) Clinical Practice Guidelines Melanoma Subcommittee, the Chair of the SITC Immunotherapy Resistance Committee since 2020 which has developed definitions for immunotherapy resistance in multiple contexts, the co-Chair and then Chair of the SITC Science and Research Subcommittee, and most recently the Chair of the SITC Policy Committee.

SITC Election Platform Statement

What are the two or three critical issues facing the field of cancer immunotherapy?

Cancer immunotherapy has transformed the standard of care management of multiple malignancies. Despite this progress, most patients either do not respond to or will develop resistance after initial benefit from immunotherapy. The most important issue facing our patients, and thus the field, is immunotherapy resistance. We need to better define resistance clinically, link these definitions to mechanisms of resistance, and develop strategies to overcome resistance. This will require dedicated efforts to collect and analyze biospecimens from patients treated with immunotherapy to understand which patients will benefit from therapy and help understand why treatment does or does not work. To realize success in this space, teams of investigators spanning the clinical-translational-bench research continuum will need to be built, and academic and industry partnerships will need to be strengthened.

A second issue that the field must address to optimize the use of immunotherapy for patients with cancer is that of toxicity. When combinatorial chemotherapy regimens were developed in the latter half of the 20th century, the key discoveries that allowed for long-term survival included the development of potent anti-emetics and growth factor support. Similarly, addressing toxicity will be just as important for the realization of long-term survival for most patients treated with cancer immunotherapy, but the challenges are even greater. As the mechanisms of anti-tumor efficacy and toxicity are similar, research is sorely needed to determine what differences are driving anti-tumor immunity and the loss of tolerance associated, for example, immune related adverse events with immune checkpoint inhibition (ICI). Further, as new therapeutic approaches such as bi- and tri-specific molecules, T-cell engagers, vaccines, and cell therapies are emerging, and ICIs are being used earlier in the disease course for more indications (e.g. adjuvant and neoadjuvant therapies), teasing out the distinct mechanisms of efficacy and toxicity is more critical than ever.

Finally, the most existential issue facing the field is the dual crises of funding scientific investigation and the weakening of institutions that support the translation and implementation of breakthroughs made by medical researchers.

What is Your Vision for SITC?

SITC began as a society of like-minded individuals embarking on a remarkable journey to transform the management for cancer patients through collaboration, innovation, and an eye towards translation into the clinic. Over its 40-year history, SITC has retained this ethos and grown to include education of clinicians, advocacy of its mission, and mentorship of the next generation as additional core values. Over the next 40-years and beyond, I expect continued growth of its membership, expansion of its annual meeting ability to highlight the most groundbreaking clinical trial results in addition to translational and bench research advances, and intensification of its advocacy to educate a broader group of stakeholders about the fruits of investing in immunotherapy research and development. The future is uncertain, but the path forward for the society will be an advocacy approach that engages with patients, researchers, regulators, funding bodies, and policy makers. SITC is well-positioned to be a leading voice in these challenging times.

SITC Election Platform Statement

What are the two or three critical issues facing the field of cancer immunotherapy?

There are a number of scientific areas in the field of cancer immunotherapy where enormous progress is possible.

  • We have a unique opportunity to apply novel tools such as AI, spatial analysis and an ability to evaluate changes in the immune system over time, to enhance our basic understanding of the relationship between malignancy, the immune system and cancer immunotherapy.
  • We need to learn more about the complex and interactive mechanisms of action and kinetics of immunotherapy as we work to design and test regimens containing the most rational combinations of drugs, optimally sequenced, and tested in right patients.
  • We should continue to explore how cancer immunotherapy research can be applied earlier in the course of cancer, including in patients with premalignant disorders, to reduce the burden of cancer for those we serve.

What is Your Vision for SITC?

The remarkable progress in the field of cancer immunotherapy has been possible because of joint efforts and collaboration among scientists in academia, government, and the private sector, as well as close interactions with patients and advocates. The next chapter in the incredible success story of cancer immunotherapy is now under threat as the collaborative culture and approach that has been the hallmark of SITC is not well understood by some who view science through an adversarial lens. SITC needs to remain at the forefront of the science while also assuring the public and governmental leaders recognize that progress is dependent on collaboration, and collaboration is based on mutual respect and support for all those making vital contributions. This includes recognizing the vital roles played by basic scientists, translational investigators, clinical investigators, population scientists, patients, advocates, academics, governmental employees, regulators and those in the private sector. Vital contributors to progress in cancer immunotherapy include experienced investigators and trainees who were born in the United States and in countries around the world. If I am fortunate enough to have the opportunity to serve as a member of the SITC Board of Directors, I will leverage my experience as a researcher, cancer physician, administrator and advocate to support SITC science, and the national policies on which that science depends.
