A single dose of a PD-1 inhibitor before surgery predicts outcomes in melanoma patients

Medical Xpress | February 25, 2019

A single dose of a PD-1 inhibitor before surgery for melanoma can put patients in remission. Researchers from the Abramson Cancer Center at the University of Pennsylvania, who documented this finding in the largest cohort of patients to be treated with anti-PD-1 drugs before surgery, also showed that immune responses brought on by this therapy can peak as early as seven days after treatment—much earlier than previous studies have shown. Patients in this study completed up to a year of anti-PD-1 therapy after surgery, and those with complete responses after the initial dose have remained cancer free for more than two years—the longest follow-up data to date for a trial evaluating this treatment approach for patients with melanoma. Further, researchers also identified patterns in the way melanoma that comes back after surgery adapts to develop resistance to PD-1 inhibitors, potentially paving the way for greater understanding of how best to help these patients. The findings appear in Nature Medicine today. "Knowing so much earlier whether or not patients are responding to PD-1 inhibitors may give us the ability to guide them to the most appropriate therapy with the greatest chance for success," said the study's lead author Alexander C. Huang, MD, an instructor of Hematology-Oncology in Penn's Perelman School of Medicine and a Parker Bridge Scholar through the Parker Institute for Cancer Immunotherapy.

Oracle and Oxford Nanopore Team Up to Improve Healthcare and Speed Discovery of New Medical Breakthroughs

Oracle | September 16, 2021

Advances in DNA/RNA sequencing promise to revolutionize how medical communities identify, detect, and treat diseases and manage public health threats. To make this technology more accessible and increase its impact, Oracle has teamed up with Oxford Nanopore Technologies, the company behind a new generation of high-performance, rapid, scalable, and accessible sequencing technology. Oracle and Oxford Nanopore have recently begun a collaboration to jointly explore several potential new solutions that would use genomic sequencing running on Oracle Cloud Infrastructure (OCI) to help speed medical breakthroughs and improve patient care. Scientific researchers in more than 100 countries are already using nanopore sequencing to further their understanding of biology in a range of areas including human and cancer genetics as well as plant, animal, and environmental analyses. In addition, nanopore sequencing has been used for pathogen analysis, including the outbreak surveillance of tuberculosis, food-borne pathogens, Ebola, Zika, Lassa fever, dengue fever, influenza, and most recently COVID-19. As part of the collaboration, Oxford Nanopore will be using OCI in applied and clinical markets. Leveraging the high performance, security, and extensive reach of Oracle Cloud, Oracle and Oxford Nanopore will have the ability to extend population-scale genetic sequencing across the globe. The organizations will also take on several ambitious projects spanning epidemiology, whole-genome sequencing, and healthcare and drug discovery. This includes integrating Oxford Nanopore's DNA/RNA sequencing capabilities and data into Oracle's broad portfolio of healthcare and life sciences applications to strengthen the links between genomics, medical treatment, and drug development. Oxford Nanopore's innovative sequencing technology is unparalleled in the market for its ability to generate rich, accurate genomic data at any scale, from handheld devices to ultra-high output installations, By integrating genomic data into our existing applications and cloud infrastructure solutions, we can get these powerful tools into the hands of more people to solve critical health issues faster and improve patient outcomes to usher in a new era of genomic breakthrough. - Mike Sicilia, executive vice president of Oracle Vertical Industries. In parallel, Oracle has committed to investing £150 million in Oxford Nanopore, subject to customary conditions. About Oracle Oracle offers integrated suites of applications plus secure, autonomous infrastructure in the Oracle Cloud.
