Friends has been successful due to convening the right people at the right time and putting forth revolutionary, yet realistic ideas. Through collaborative and meaningful initiatives, Friends’ programs foster solutions to issues encountered by researchers and regulators as they strive to translate discoveries into safe and effective new treatments. Each year, Friends convenes working groups, hosts scientific conferences, and conducts research on a range of topics to inform regulatory policy, oncology drug development, and clinical practice. These venues are vital to facilitating the creative partnerships and dialogue that ultimately yield many whitepapers, scientific abstracts, and peer-reviewed manuscripts led by Friends that infuse innovative ideas and strategies into the collective science and regulatory landscape. In 2019, we expanded our research portfolio with several large scale pilot projects that are represented in this book. These pilot projects are designed to expand our science un- derstanding as well as inform policy. The 2019 Scientific Report represents Friends’ ongoing mission to drive collaboration among partners from every healthcare sector to power advances in science, policy, and regulation that speed life-saving treatments to patients. This journal is intended to be a resource for those in the drug development and regulatory space and informative for those interested in science and regulatory issues in oncology. The scientific report contains the full text of the Friends 2019 publications and whitepapers, which focused on several key themes: 1 Real-world evidence: Characterizing the use and power of real-world data 2 Patient-focused drug development: Aligning patient needs with oncology drug development 3 Complex biomarkers: Informing development and standards for diagnostic tests 4 Optimal drug development: Addressing emerging opportunities REAL-WORLD EVIDENCE: CHARACTERIZING THE USE AND POWER OF REAL-WORLD DATA Only 35% of cancer Real-world evidence (RWE) is generated from data collected trials include sicker, from patients receiving routine care. This information is recorded in the patient’s medical record, medical billing and higher risk patients. claims documents, and patient registries. Although the type of Over 60% of RWE gathered varies depending on the source, this data can help researchers gather insights into patient characteristics, cancers occur in treatment patterns, and outcomes of patients treated outside people 65 and older of clinical trials. but only 22% Randomized controlled trials (RCTs) are the gold standard for of clinical trial demonstrating evidence of safety and efficacy in the development of new therapies. While this will always be the case, there may be patients are over 65. opportunities for real-world data (RWD) to provide important sup- plemental information to inform the use of therapies. For example, clinical trials use eligibility criteria to select for specific patient pop- ulations that help maximize the ability to measure treatment effica- cy. While this patient selection can improve the statistical quality of the clinical data, it may not reflect the broader patient population Specific patient that will likely receive the drug in clinical practice. The use of RWD can help assess the use and effectiveness of a therapy in “real- populations world” patients. and characteristics Increasingly, the healthcare community is grasping the capabilities can be collected of RWE and its potential role in facilitating drug development. Congress has also recognized this potential and has included man- from several RWD dates in the 21st Century Cures Act and the Prescription Drug User sources in a similar Fee of 2017 for FDA to explore the use of RWE in prescription drug regulation. The FDA’s Framework for Evaluating RWD/RWE for Use manner to produce in Regulatory Decisions will “evaluate the potential use of RWD to similar results— generate RWE of product effectiveness to help support approval of new indications for drugs… or to help to support or satisfy post this will increase approval study requirements.” confidence in results In response to this growing need, the Friends RWE Pilots 1.0 and from studies with 2.0 were first of their kind efforts that brought together a dozen real-world data. key stakeholders to study RWE for use in drug development and evalutation over time. The collective results of this work are help- ing inform the use of RWD/RWE. 4 friends of cancer research • Specific patient populations and characteristics can be collected from several RWD sources in a similar manner to produce similar RWE PARTNERS results—this will increase confidence in results from studies with real-world data Aetion • Some real-world endpoints correlate to endpoints commonly ASCO CancerLinQ & Concerto used in clinical trials—this suggests that real-world endpoints HealthAI Cancer Research Network could be used as proxies for clinical trial endpoints in real-world COTA data and warrants further investigation FDA Flatiron Health IQVIA™ PUBLICATIONS RELATED TO THIS TOPIC Mayo Clinic • An Exploratory Analysis of Real-World End Points for Assessing Outcomes McKesson Among Immunotherapy-Treated Patients with Advanced Non-Small-Cell Lung NCI SEER-Medicare Linked Cancer (Page 11) Database • Validating Real-World Endpoints for an Evolving Regulatory Landscape OptumLabs® (Page 26) PCORnet Syapse Tempus PATIENT-FOCUSED DRUG DEVELOPMENT: ALIGNING PATIENT NEEDS WITH ONCOLOGY DRUG DEVELOPMENT Patient engagement in research and clinical trials has evolved Some real-world over time.
