Angiosarcoma Patient Celebrates 7-Year Remission with Pioneering Use of PD-1 Inhibitor: Every Cure Unleashes AI to Ensure No Treatment is Left Overlooked

An Angiosarcoma patient facing a grave prognosis found a lifeline in a repurposed PD-1 inhibitor, a treatment hidden in the medical literature for three years.

Every Cure and its partners are building on this breakthrough, deploying innovative AI algorithms that evaluate the potential of every drug for every disease. The efforts have already begun to spotlight promising candidates for further study, transforming the way we approach medical treatments and patient care.



PHILADELPHIA, PENNSYLVANIA – August 2, 2023– A patient cured of angiosarcoma from a pioneering use of a repurposed PD-1 inhibitor is celebrating seven years of remission after the treatment was hidden in the medical literature before being discovered by Every Cure Co-founder Dr. David Fajgenbaum and his team at the University of Pennsylvania. Every Cure and its partners are developing medical databases and AI algorithms to ensure no potential cure remains overlooked among the vast number of medical studies.

In 2016, Michael was confronted with a diagnosis of metastatic angiosarcoma and given a prognosis of just three months. Fajgenbaum’s team unearthed a 2013 study indicating high levels of PD-L1 in three patients with Michael’s form of cancer and then confirmed the same results in Michael’s tumor. PD-L1 is a molecular strategy cancer cells use to avoid immune detection. The positive PD-L1 results in Michael’s tissue led to the pioneering use of pembrolizumab, a PD-1 inhibitor, used to treat other cancers, but had not been known to treat Angiosarcoma.

The impact was immediate. Just days after receiving his first dose of pembrolizumab, Michael experienced a profound change. “I received the treatment on a Friday morning, and by Monday I woke up pain-free, feeling better,” Michael recalls. A follow-up PET scan confirmed the success of the treatment: Michael was disease-free. He has now been in remission for over 7 years. “Michael became the first patient that we were aware of at the time to be treated with a PD-1 inhibitor for angiosarcoma. It’s now been used so many times in other patients and been so effective, that it is considered standard of care, and it’s recommended by the National Comprehensive Cancer Network,” Fajgenbaum shares.

Every Cure is committed to ensuring no potential cure remains overlooked in the vast number of medical studies performed each year. To this end, Every Cure is harnessing the power of artificial intelligence (AI) to scan through medical studies, databases, and expert insights to develop a pioneering algorithm that evaluates the potential of every drug to treat every disease. The Every Cure LinkMap has initially ranked all 3,000 FDA-approved drugs to treat all 12,000 human diseases, generating 36 million evaluations. Every Cure is currently analyzing the top results from its initial findings in its Every Cure LinkMap, in addition to consulting industry experts and patient organizations, to identify the most promising candidates to launch into clinical trials.

Every Cure, a 501(c)(3) non-profit organization, is seeking additional funding to optimize its algorithms further and evaluate its highest-ranked results for direct patient application. The organization is also actively seeking partnerships for data contributions. “Michael’s story highlights the vital importance of our work,” said Every Cure co-founder and CEO, Grant Mitchell. “There are countless papers published that could hold the key to life-saving treatments for new diseases, yet this information often goes unutilized because the system is broken. Our aim is to develop a new algorithm that prioritizes the potential of every drug to treat every disease. We’re ensuring that no paper containing potentially life-saving insights will ever be overlooked again and no patient is told ‘we’ve tried everything’ when a life-saving drug is sitting on the pharmacy shelf.”

In the spirit of continuing our mission and to keep bringing potential cures to light, we invite everyone to join our cause. Every Cure relies on the generosity of individuals and organizations to fund this critical work to save lives like Michael’s, and every donation, regardless of size, brings us closer to a world where every potential cure is discovered and utilized.

About Every Cure

Every Cure is a nonprofit organization dedicated to unlocking the full potential of every existing medicine to treat every disease possible. Repurposing existing drugs is the fastest and most efficient way to treat diseases with the greatest return on investment for saving lives. However, systemic barriers impede repurposing, so patients suffer while potential treatments are not fully utilized. Every Cure overcomes these barriers to systematically identify and advance promising repurposing opportunities and save lives. Every Cure is taking a revolutionary and disruptive approach to overcome these systemic barriers by developing a comprehensive, open-source data engine to generate predictive efficacy scores for all 3,000 drugs against all 12,000 diseases and rapidly advance treatments to patients. In partnership with academia, industry, and government, Every Cure is integrating proprietary and public data into a comprehensive dataset, optimizing AI ranking algorithms, validating the most promising drug-disease matches, performing trials, and ensuring patient access to effective therapies. Every Cure announced its launch in September 2022 at the Clinton Global Initiative.
