President's Message - July 2019

Dear Colleagues,

Summer is already here, and our attention is increasingly focused on the 34th Annual Meeting & Pre-Conference Programs (SITC 2019), scheduled for Nov. 6-10, 2019. Organizers and staff have already put more than a year’s worth of planning and work into this meeting, and the pace of preparations will increase substantially over the next few months.

This year our meeting will return to the Gaylord National Hotel & Convention Center in National Harbor, Md. The venue has hosted many successful SITC programs and this fall will be no different. The Annual Meeting & Pre-Conference Programs connects all of us in the cancer immunotherapy field, including established and leading academic and government investigators in basic, translational and clinical research, early career investigators, patient care providers, industry professionals, regulatory colleagues and patient advocates.

This summer, SITC is launching its all new Career Connections initiative to make it even easier to connect with each other in ways that could foster new, long-lasting professional relationships. This program will connect job seekers and talent seekers in the cancer immunotherapy field with an enhanced year-round online platform and new opportunities for in-person connections at SITC 2019. Stay tuned for more details about the Career Connections initiative in the next few weeks and months.

We’ve observed a surge in quantity and quality of abstract submissions to the SITC Annual Meeting in recent years as our field has grown and matured. One of our goals for the Annual Meeting over the last several years has been to increase opportunities for oral abstract presentations, in order to better recognize and share the work and to give more opportunities for oral abstract presentations to early career investigators. This year we are nearly doubling the number of oral abstract presentations over the previous year. For those considering submitting an abstract to SITC 2019, don’t forget the deadline to submit a regular abstract or late-breaking abstract application is Aug. 1, 2019, at 5 p.m. PDT.

We continue to develop collaborations with other professional societies and organizations. We owe this spirit of collaboration to several of our past presidents. The newest collaboration at our upcoming Annual Meeting, this time with the American Society of Hematology, is scheduled for Thursday, Nov. 7, 2019, from 1-5 p.m. EDT, and will be co-chaired by Katy Rezvani, MD, PhD (The University of Texas MD Anderson Cancer Center), and John M. Timmerman, MD (University of California, Los Angeles). This program will feature exciting presentations on the current state of research in hematologic malignancies.

We are continually adding new program, session and speaker information to the SITC 2019 itinerary. For the latest information regarding the SITC 2019 schedule and session information, please visit the SITC 2019 website today. Hotel rooms in National Harbor are limited and rapidly being reserved, so please don’t hesitate to confirm your registration today and secure your lodging in National Harbor.

Great scientific organizations are often associated with high quality journals publishing impactful, state of-the-art research. We are very proud to report that the Journal for ImmunoTherapy of Cancer (JITC) increased its impact factor this year to 8.676. The impact factor places JITC in the top 3 percent of all fully open access oncology journals and ranks it in the top 8 percent of all journals published in the oncology and immunology categories. Congratulations to JITC Editor-in-Chief Pedro Romero, MD, the JITC Editorial Board, its vast collection of reviewers and SITC staff for hitting it out of the park again. Please consider submitting your best research to JITC or becoming a reviewer for the journal as we continue to grow its reputation and impact in oncology.

Finally, the 2019 SITC Election is fast approaching. Scheduled for July 10-24, 2019, SITC regular members and emeritus members will consider six candidates to fill three future openings for three-year terms as At-Large Directors on the SITC Board of Directors. Thank you to this year’s candidates who have offered their time and expertise to serve our Society.

Please visit the SITC website today to learn more about each of this year’s six candidates (or continue scrolling to view their names), including their biographies and positions statements. If you are not currently a SITC member, I hope you’ll consider joining SITC today.

Sincerely,

President's Message - June 2019

Dear Colleagues,

For 35 years, a primary purpose of the Society for Immunotherapy of Cancer (SITC) – through its growth and multiple iterations – has been to bring together top scientists and clinicians in our field. SITC has served as the catalyst for these professionals to convene and share their latest research achievements, and through interaction and collaboration, to spur future advances and breakthroughs in the field.

Our organization was originally founded in 1984 by 40 charter members as the Society for Biological Therapy (SBT). In the past 35 years, much has changed, both in immuno-oncology and our society, including our name. SITC has grown with the field – eclipsing 2,400 members in 2018 – and remains at the forefront of scientific and clinical advances in cancer immunotherapy.

Beginning tomorrow, June 1, SITC will join our colleagues at the Cancer Research Institute to celebrate Cancer Immunotherapy Awareness Month™. During this month, we will bring attention to the many ways our society, through the contributions and dedication of its members, seeks to educate health care professionals and patients, and to enable research that will yield our field’s next breakthroughs. On our website and various social media channels, including Twitter and Facebook, SITC will feature a different program, resource or SITC initiative each day of the month. These activities are designed to create awareness of cancer immunotherapy and the depth and breadth of our society’s contributions to the field.

Also, on Friday, June 14, please join me in wearing white to honor and celebrate the work of the many researchers and clinicians in our field. Please consider purchasing a SITC Cure T-shirt, through a donation to the SITC Forward Fund, to wear on June 14, and then download our “Why I Wear White” flyer to share what drives your commitment to the cancer immunotherapy field. For me, every patient in my clinic who is alive today only because he or she received interleukin-2, or anti-PD-1 and or anti-CTLA-4, and every patient I see for whom these therapies were not enough to provide benefit, is another reminder of why I am committed to advancing these therapies in the clinic, and why I wear white on June 14. Take a selfie or group photo and tag SITC on social media to help us spread the word about cancer immunotherapy research.

As a final reminder, for those of you who will be in Chicago this weekend, please consider joining SITC at Buddy Guy’s Legends (700 S. Wabash Ave.) on Sunday, June 2, for the return to the stage of The CheckPoints, SITC’s house band. Doors open at 8 p.m. for The CheckPoints: Rockin' for a Cure, SITC’s annual fundraiser for the Forward Fund.

Sincerely,

President's Message - May 2019

Dear Colleagues,

The Society for Immunotherapy of Cancer (SITC) hosts dozens of educational and scientific meetings each year to support the primary mission of the society, which is to improve cancer patient outcomes by advancing the science and application of cancer immunotherapy. In this letter I bring to your attention this year’s interim workshops, which provide a forum to address specific important and evolving areas in our field. The workshops will focus on cancer immune responsiveness and adoptive cellular therapies and will be organized by prominent members of the immuno-oncology community, including Alessandra Cesano, MD, PhD (NanoString Technologies, Inc.), Francesco M. Marincola, MD (Refuge Biotechnologies, Inc.), and Katayoun Rezvani, MD, PhD (The University of Texas MD Anderson Cancer Center).

Both multi-day programs will bring together some of the foremost experts and future leaders in the science and clinical application of immune therapies. Participants will review current progress as the basis to initiate discussions of challenges and potential solutions to advance the field. The assembled researchers and clinicians usually produce a formal output from the meeting, often published in the Journal for ImmunoTherapy of Cancer (JITC), the society’s open access, peer-reviewed online journal.

On Sept. 4-5, 2019, in Houston, Texas, the SITC Cancer Immune Responsiveness Task Force will, for the second consecutive year, host a Cancer Immune Responsiveness Workshop. The focus on understanding cancer immune responsiveness is timely and critical for our field, and could lead to improved prognostic and predictive biomarkers, improved patient selection, more rational combination strategies in the clinic and more efficient clinical development of single agents and combinations. Didactic lectures and working groups will cover key topics such as the role of host genetics and epigenetics in immune responsiveness; transcription patterns indicative of distinct tumor immune landscapes; and more. Immediately following, on Sept. 5-6, 2019, SITC will host the Adoptive Cellular Therapies Workshop. The field of adoptive cell therapy is receiving increased attention from scientists, clinicians, patients, regulators and payors following the 2017 U.S. Food and Drug Administration approval of Chimeric Antigen Receptor (CAR) T cell therapies for patients with lymphoma and leukemia. This is, in my opinion, one of the most exciting and promising areas of clinical medicine, and this program will bring together experts to address the evolving science of cell engineering, novel strategies to improve the overall risk/benefit profile, clinical development, regulatory challenges and more.

Additionally, three collaborative sessions, taking place the morning of Sept. 5, will allow attendees from both workshops to discuss common challenges of the field and new concepts that impact cancer immune responsiveness and adoptive cellular therapies.

Please consider joining us for both programs over the course of three days. Participants who register for both workshops will receive a 30 percent discount.

Finally, for those attending the 2019 American Society of Clinical Oncology Annual Meeting in Chicago, I hope you consider joining me, the SITC staff and your fellow SITC colleagues and friends at SITC’s annual fundraiser for the Forward Fund, The CheckPoints Party. Come and party with the Checkpoints band (stars in the true sense of the word, including 2018 Nobel Laureate James P. Allison, PhD) beginning at 8 p.m. on Sunday, June 2, at Buddy Guy’s Legends (700 S. Wabash Ave., Chicago).

VIP tickets are available online or by calling 414-271-2456. General admission at the door is available on a first-come, first-served basis, with suggested donation of $30. Proceeds support SITC’s Forward Fund, providing grant opportunities to promising early career scientists in the field. You can learn about some of the young investigators who have benefited from the SITC Forward Fund by viewing the Faces of the Forward Fund.

Sincerely,

President's Message - April 2019

Dear Colleagues,

I wish you all a happy spring. While I certainly do not hope for the next seven months to speed by, the Society for Immunotherapy of Cancer’s 34th Annual Meeting & Pre-Conference Programs (SITC 2019), to be held Nov. 6–10, will no doubt be here before we know it. Registration is already open for SITC members (and opens for all on April 9). This is our society’s cornerstone conference, and this year we return to the Gaylord National Hotel & Convention Center in National Harbor, Md. I am already excited to see and welcome back existing members and to meet the new members of our Society.

Last year, 5,000 professionals in the cancer immunotherapy field attended our Annual Meeting & Pre-Conference Programs, a 36 percent increase over 2017. Similarly, we received nearly 800 abstract submissions, a 34 percent increase year-over-year. For me personally and I’m sure for all of us involved in the Society, it has been astounding to witness the growth of our annual gathering of basic scientists, translational researchers, clinicians, industry and governmental representatives and others in recent years.

This year, the Annual Meeting will feature several new oral abstract presentation opportunities. Increasing the number of oral presentations has been a key goal of our Board for several years, affording researchers, and in particular younger investigators, additional time to share the findings of their work and connect to others in the field. First is a Poster Symposium on Thursday, Nov. 7, from 5:30 – 7:30 p.m., which will comprise several short abstract presentations and expert discussants. Secondly, the number of rapid oral abstract sessions has doubled; two sessions will be held on Friday and two on Saturday. Half of these rapid oral abstract sessions will feature clinical advances in the field. Finally, three designated clinical trial sessions will ensure the conference captures the important clinical trial work being done in the field:
  • High Impact Clinical Trials: Friday, Nov. 8, 4:50-6:15 p.m.
  • Single Agent Phase 1 Clinical Trials: Saturday, Nov. 9, 3:45-5 p.m.
  • Combination Phase 1-2 Clinical Trials: Saturday, Nov. 9, 5:15-6:30 p.m.
More than 16 months of planning and preparations go into each Annual Meeting. Dedicated committee members, lead by Annual Program Committee Chair Sandra Demaria, MD (Weill Cornell Medicine), and assisted by the Board of Directors and faculty, work tirelessly to ensure program schedules contain impactful data and meaningful panel discussions. It’s this devotion and enthusiasm that brings the highest quality data to the SITC’s Annual Meeting & Pre-Conference Programs. For immune therapy of cancer, I believe it is the most influential conference in the field.

Please join me in congratulating our recently announced 2019 Richard V. Smalley, MD, Memorial Award and Lectureship recipient Olivera (Olja) J. Finn, PhD, of University of Pittsburgh School of Medicine. Dr. Finn will deliver her highly anticipated keynote address during the Annual Meeting, on Friday, Nov. 8. I’m also very pleased to announce that Ronald N. Germain, MD, PhD, of the National Institutes of Health, will deliver Saturday’s keynote address.

Please remember that SITC members receive discounted SITC 2019 registration rates and early access to housing. There are so many reasons to become a SITC member, and the savings for attending just part of SITC 2019 will more than cover the cost of a membership. So don’t wait, join SITC today to save on your SITC 2019 attendance.

Although our Annual Meeting & Pre-Conference Programs is our most highly attended program, we offer a variety of other opportunities for education and scientific exchange throughout the year, including interim workshops. Two exciting and timely 2019 workshops – dedicated to cancer immune responsiveness and adoptive cellular therapies – are scheduled for Sept. 4–6, 2019, in Houston, Texas, and registration is now open. Participants who attend both back-to-back workshops will receive a 30 percent discount on registration.

Sincerely,

President's Message - March 2019

Dear Colleagues,

Last month, the Society for Immunotherapy of Cancer (SITC) recognized and celebrated International Day of Women and Girls in Science. With International Women’s Day approaching (March 8), it reminds us of our responsibility and commitment to help advance the careers of women in the cancer immunotherapy field.

As the successor to the Society for Immunotherapy of Cancer’s (SITC) first female president, Lisa H. Butterfield, PhD, I am privileged to continue and expand our society’s support of women involved with research and development in the laboratory, clinic, industry and all other areas related to immuno-oncology.

Dr. Butterfield championed many causes, programs and initiatives during her tenure as SITC President, including working to ensure the society was recognizing and encouraging professional development for women. This included hosting women’s receptions at the past two SITC Annual Meetings, offering women an opportunity to network, celebrate successes and discuss important topics critical to their advancement.

Through Dr. Butterfield’s continued leadership, and with support from many of our fellow colleagues, SITC will host its first-ever Women in Cancer Immunotherapy Network (WIN) Leadership Institute this summer. Scheduled for Aug. 19–20, 2019, in Seattle, the SITC WIN Leadership Institute will provide a forum for attendees to discuss important topics relevant to their advancement, including how to break through the glass ceiling; negotiation tactics; and critical leadership skills. Also of note, the program is free to attend. Women interested in attending this exciting one-and-a-half-day program are encouraged to submit an application by April 15.

SITC is currently recruiting our members to join the Women in Cancer Immunotherapy Network Database. This database will contain a repository of leaders in the field of cancer immunotherapy with an interest in serving as subject matter experts for a variety of potential roles, such as presenting data at SITC meetings, conducting article reviews for the Journal for ImmunoTherapy of Cancer (JITC), serving in organizer roles to plan future meetings and more.

Those interested in being considered for such future opportunities can submit their credentials via the SITC Volunteer Portal, a members-only benefit. If you have questions about the database, please contact Senior Administrative Manager Rosanne Stelpflug.

I, along with all the leadership of SITC, wholeheartedly support the efforts of the WIN. The WIN is a key part of our society’s commitment to developing future female leaders in science and medicine – some who will hopefully follow Dr. Butterfield’s footsteps and serve as SITC President in the future. I’m also sending a reminder that SITC member registration for the 34th Annual Meeting & Pre-Conference Programs (SITC 2019) opens soon – on March 26. Scheduled for Nov. 6–10 in National Harbor, Md., SITC 2019 will take our society to new heights and I look forward to seeing new and familiar faces this fall.

Sincerely,















Mario Sznol, MD

President's Message - February 2019

Dear Colleagues,

As I enter my second month as President of the Society for Immunotherapy of Cancer (SITC), I am energized in our society’s efforts to continue our growth and success into this new year. As we set the stage for the future, I wanted to offer a brief history of SITC for those new to the society, to acknowledge and celebrate our past, all made possible by a dedicated (and growing) family of SITC members.

SITC was originally founded in 1984 by 40 charter members as the Society for Biological Therapy (SBT). At the time, enthusiasm for cancer immunotherapy was driven by investigations of early cancer vaccines, interferons, interleukin-2 and other types of immune modulators. Fundamental discoveries in molecular biology and immunology over the ensuing years provided the foundation for advances in cancer immunobiology, and consequently ushered in the modern era of cancer immunotherapy, which includes transforming therapies such as the immune checkpoint inhibitors and CAR-T cells. Members of our Society were key drivers of many of these advances, in the lab and the clinic, and through critical roles within industry and government.

I attended my first meeting of the society, then SBT, in approximately 1989, and witnessed the rapid advances in understanding the nature of host anti-tumor immunity over the next decade. Based on a growing body of exciting preclinical data, many agents were brought to clinical trials by dedicated researchers, although with limited clinical success. Nevertheless, members of our society remained steadfast in their efforts to develop highly effective cancer immunotherapies. During the SBT 2002 business meeting, members voted to officially change our name to the International Society for Biological Therapy of Cancer (iSBTc). This change was enacted so that our name would reflect our emphasis and concentration on cancer while embracing and valuing our expanding member footprint across the globe. We experienced further change in 2010 when members voted to refresh the name to the Society for Immunotherapy of Cancer, a moniker that captures our focus and expertise.

The field as a whole, and our society more specifically, has come a long way in the past 35 years. Immunotherapy is not only a viable alternative to other treatments, but now in many malignancies, the most important component of treatment for cancer patients. Improved patient response rates and overall outcomes have undoubtedly played a substantial role in our society’s growth and prosperity, particularly in the past seven years. Since 2012, SITC membership has grown more than 300 percent, from 601 members to 2,457 in 2018.



The diversity of our membership has grown over the years and our society adjusted to reflect the change in composition, adding categories of nurses, pharmacists and patient advocates in recent years. In total, SITC maintains eight member categories for professional and personal classification purposes:

  • Regular
  • Affiliate
  • Emeritus
  • Nurse and Advanced Practice Provider
  • Patient
  • Patient Advocate
  • Pharmacist
  • Student and Scientist-in-Training


Historically and to this day, our regular member category is our most popular, growing to more than 1,600 professionals in the field in 2018, including basic and translational scientists and practicing oncologists. I find it interesting that while the number of regular members has increased by nearly 450 in the past three years, the category’s representation within the overall SITC membership body has actually declined by three percent since 2016. All other member categories – save emeritus, which has remained steady, comprising 18 members – have increased during the same timeframe, suggesting our reach and effect on the greater cancer community continues to grow. It is clear, though, that once a regular member joins SITC, they find a home in our society, as our retention rate among this category is a staggering 88 percent.

While we know that access to discounted registration rates at SITC programs remains a valued member benefit, our members repeatedly tell us that the ultimate rewards of a SITC membership are the indispensable professional relationships built through society involvement. These relationships expand professional networks and set the stage for meaningful collaborations that spark the next advances in the field, all with the same goal of improving patient outcomes.

I appreciate each and every one of our society’s members, many who have already renewed their memberships for the balance of 2019. Continue reading this month’s Immune Monitor to learn more about the value of a SITC membership. If you’re not currently a member, I encourage you to consider becoming a part of the SITC family.

Sincerely,

President's Message - January 2019

Dear Colleagues,

I am excited and honored to address you in my first monthly message as President of the Society for Immunotherapy of Cancer (SITC). I have enjoyed the past two years as SITC’s Vice President, supporting Lisa H. Butterfield, PhD, SITC’s first female president, during her tenure as leader of our society. Thank you, Dr. Butterfield, for setting a foundation for the increased inclusion, development, and celebration of women in cancer immunotherapy. The society appreciates your continued leadership and commitment to the field and our organization!

As I assume this role on the heels of another successful year for SITC – which includes reaching new marks within our membership and a record-breaking 5,000 attendees at our Annual Meeting & Pre-Conference Programs – I am looking forward to helping continue our society’s tremendous growth. During my tenure as President, I will work to sustain SITC’s commitment as the leading member association in cancer immunotherapy. I will also ensure SITC remains the host to the most important meeting in the field, as we provide a platform for the presentation of phase 1 clinical trial data that provide insight into the future of immuno-oncology.

SITC has many exciting programs and initiatives slated for the next 12 months, all of which seek to improve cancer patient outcomes by advancing the science, development and application of cancer immunotherapy. A more complete listing of these initiatives is provided below, and I would like to highlight a few occurring in the near future.

It is critical for SITC to continue its emphasis in growing the next generation of leaders in cancer immunotherapy and tumor immunology. This is an area I am keenly focused on and support heavily. To that end, SITC is pleased to continue to offer SITC Fellowship Awards in 2019. Made possible through generous support from our industry partners, SITC Fellowships honor some of the brightest young minds in the field. The development and celebration of young investigators in our field is an important strategic priority of the society and one of my foci as President.

Additionally, registrations are open for SITC’s first Cancer Immunotherapy Winter School. Scheduled for Feb. 18-22 in Mesa, Ariz., this new program, tailored to early career scientists and clinicians as well as those new to the field, will teach the fundamentals of cancer immunotherapy and allow attendees to choose from a variety of tracks that focus on topics most relevant to them. Space is limited so register early! Also, SITC will host its first Meet-the-Expert Webinar on Thursday, Jan. 17 at 12:30 p.m. CST. This hour-long webinar, moderated by Sruthi Ravindranathan, PhD (Emory University), and with participation from presenter Vionnie W.C. Yu, PhD (Novartis Institutes for Biomedical Research), will focus on the topic Careers in Industry. Please click here to register for this free online event.

SITC continues its 2018-19 Advances in Cancer Immunotherapy™ (ACI) regional education program series, with events currently confirmed for Sacramento, Calif., on Jan. 10 in Houston on Feb. 9 and in Portland, Ore., on Feb. 21. Also, we look forward to hosting two, back-to-back thoughtful and engaging interim workshops, focused on cancer immune responsiveness and resistance; and adoptive cellular therapy. Stay tuned for information regarding location, registration and lodging.

If you haven’t already, I hope you’ll consider joining or renewing your SITC membership in 2019 to enjoy a variety of member benefits, including early access to register for the 34th Annual Meeting & Pre-Conference Programs, scheduled for Nov. 6-10, 2019, in National Harbor, Md.

I am excited to strengthen existing, and build new, relationships with leaders in the field as we work together to continue the growth and success of the society.

Sincerely,















Mario Sznol, MD
