Tom Marsilje, Ph.D. and Fight Colorectal Cancer release a new-and-improved tool that helps late-stage colorectal cancer (CRC) patients search for microsatellite stable (MSS-CRC) clinical trials sorted with a patient’s point of view in mind

Stage IV Colorectal Cancer Survivor Dr. Tom Marsilje, known to many as “Dr. Tom” or the “Currently Incurable Scientist,” released version two of his microsatellite stable colorectal cancer (MSS-CRC) clinical trial finder tool today, now called the “Late Stage MSS-CRC Trial Finder: A curated list powered by patients.” For over two years, Marsilje has personally curated MSS-CRC clinical trials and shared them through a spreadsheet, later converted to an app, with late-stage patients he met online. He partnered with Fight Colorectal Cancer in January 2017 to amplify his efforts and reach more patients, as well as secure curation support for the trials database. The tool can be accessed at The new-and-improved Late Stage MSS-CRC Trial Finder is an update of Marsilje’s spreadsheet. Flatiron Health, a healthcare technology and services company focused on accelerating cancer research and improving patient care, built the latest version of the tool, turning Marsilje’s dream into a reality.
“For over two years, my spreadsheet has served patients (and their caregivers) and offered them a curated list of potential clinical trials for them to subsequently discuss with their medical team,” said Marsilje. “The filtered list is generated from all potential MSS-CRC patient-enrolling trials, and it is based upon parameters that are most important from the viewpoint of stage IV MSS-CRC patients. This comes from not only my own personal experience as a MSS-CRC patient, but also the feedback I’ve received over the years after helping hundreds of other patients search for trials.”
As part of Flatiron’s latest internal hackathon, a team from the company not only built a patient-friendly, online platform, but programmers also automated many parts of Marsilje’s curation process. The content of the app is based on an automated search that hits AACT, a publicly available repository of all trials listed on, that is maintained by the Clinical Trials Transformation Initiative (CTTI). The search is refreshed each day for new and existing trial updates, and is then monitored by Marsilje and long-time research advocate Maia (Cee Cee) Walker. Together they systematically use Marsilje's logic model to review each trial, and post only the trials most relevant for late-stage, MSS-CRC patients to the Trial Finder website. They’re currently working with Fight CRC to train additional patient advocates who will help power the curation process. It’s important to note that the Trial Finder tool is not a comprehensive list of all CRC clinical trials - only trials that may be of greatest interest to a stage IV patient with MSS-CRC (such as Marsilje himself) and based on Marsilje’s review criteria, are included. When commenting on which trials appear in the Trial Finder, Marsilje explained:
“From my stage IV patient viewpoint, I decided I was only interested in two types of trials: 1) Trials which had a “reduced” chance of potential failure and 2) Trials that had the biggest “potential” long-term benefit.  As a patient, I had no interest in participating in a trial which had both the highest risk of failure as well as limited long-term benefit, even if the experimental therapy worked as designed. I knew that I may only have one shot at a trial, so I wanted to choose that trial wisely and make that potentially single shot count the most!”

This approach to curating a list of clinical trials is innovative, as it focuses on underscoring the patient point of view, looking specifically at the relationship between patient values and the desire to find clinical trials with meaningful impact. This effort, led by Marsilje and research advocates across the country, illustrates that patients are keenly aware of the role clinical trials can play in their lives as they search for better, more effective treatment options. Social media and information on the web have changed the game in cancer research.
“Stage IV patients and their caregivers have a sense of urgency that isn’t reflected in the systems of research,” said Nancy Roach, founder of Fight CRC. “Tom’s curating logic reflects this sense of urgency and the priorities of patients, especially patients who’ve received multiple lines of therapy. The logic will evolve over time as new approaches to treatment evolve, and we hope to use information from patients who use the tool to inform our ability to comment constructively on trial design.”

Powered by patients, goodwill and talent, the tool was built and designed during Flatiron’s most recent internal “hackathon,” a two-day event that provides Flatiron employees an opportunity to take on a grassroots side project outside of their daily work. These quarterly hackathons have been a part of Flatiron’s tradition since its founding almost five years ago. A team from Flatiron chose to partner with Marsilje and Fight CRC for one of their many projects in this latest hackathon, which they blogged about here.
“The Flatiron team includes many exceptionally talented engineers, data scientists, product managers, and oncologists, and we all have one thing in common: we are all eager to increase the number of cancer patients who participate in cutting-edge research,” said Vineeta Agarwala, M.D., Ph.D., and director of product management at Flatiron Health. “From the very first time that we spoke with Tom, we were inspired by his passion and focus to help fellow cancer patients. We immediately realized that our collaboration on the Late Stage MSS-CRC Trial Finder could have a direct and immediate impact on stage IV colon and rectal cancer patients and their families, which was the driving force behind our decision to be a part of this project."
Flatiron created a robust platform with search boxes, tool tips and printable reports to meet patient needs. While most of the software build was done over the course of the two-day hackathon by Flatiron, the full project was completed in three months, with Fight CRC’s support through volunteer time advancing research efforts.

  1. I love it. So easy to navigate. I am just starting to research this as a possible next option. So glad I waited for this tool. Thanks Tom and FightCRC.

  2. This is remarkable and so needed by stage 4 CRC patients. I had to create my own spreadsheet for my son, who died in 2014, by searching Thankfully I was a librarian experienced in online research. Sadly, it was too late for him.
