Recommendations on the Selection, Development, and Modification of Performance Outcome Assessments: A Good Practices Report of an ISPOR Task Force.

In evaluating the clinical benefit of new therapeutic interventions, it is critical that the treatment outcomes assessed reflect aspects of health that are clinically important and meaningful to patients. Performance outcome (PerfO) assessments are measurements based on standardized tasks actively undertaken by a patient that reflect physical, cognitive, sensory, and other functional skills that bring meaning to people's lives. PerfO assessments can have substantial value as drug development tools when the concepts of interest being measured best suit task performance and in cases where patients may be limited in their capacity for self-report.

Measuring What Matters to Patients in Dermatology Drug Development: A Regulatory Perspective.

Incorporating the patient voice into drug development and regulatory review process allows for the science of drug development to be more patient-centered. Dermatology is one therapeutic area where patients have the potential to provide valuable perspectives on symptoms, functional impacts, and aesthetic outcomes. Patient-reported and observer-reported outcomes play an important role in capturing concerns related to the disease or condition and its treatment.

Advancing Therapeutic Development for Pulmonary Morbidities Associated with Preterm Birth.

Chronic pulmonary and respiratory conditions associated with preterm birth are incompletely characterized, complicating long-term treatment and development of more effective therapies. Stakeholders face challenges in the development of validated, clinically meaningful endpoints that adequately measure morbidities and predict or represent health outcomes for preterm neonates. We propose in this paper a research agenda, informed by the input of experts from a 2018 workshop we convened on this topic, to advance endpoint and treatment development.

Considerations in the Assessment of Clinical Benefit with a Focus on Pain: a Regulatory Perspective.

In the USA, the regulatory standard for demonstration of efficacy of a drug is evidence of clinical benefit from adequate and well-controlled clinical trials. Understanding the natural history of disease and how treatment is expected to alter its course, and gathering input from relevant stakeholders, such as patients, caregivers, and clinicians, is essential to understand the best way to measure clinical benefit in a clinical trial. Though pain intensity has been the primary outcome measure in clinical trials for pain, an array of measures assessing clinical outcomes from multiple perspectives can allow for more comprehensive interpretation of how a treatment affects patients' lives.

Why Reinvent the Wheel? Use or Modification of Existing Clinical Outcome Assessment Tools in Medical Product Development.

Assessment of clinical benefit in treatment trials can be made through report by a clinician, a patient, or a nonclinician observer (eg, caregiver) or through a performance-based assessment. The US Food and Drug Administration (FDA) published a final guidance for industry for one type of clinical outcome assessment (COA)-patient-reported outcome (PRO) measures-in 2009 that described how FDA reviews PRO measures for their adequacy to support medical product-labeling claims. Many of the principles described in the PRO Guidance could be applicable to the other types of COAs, including instruments completed by clinicians (ie, clinician-reported outcome assessments) and nonclinician observers (ie, observer-reported outcome assessments).

Public-private partnerships in transplant drug development.

The Transplant Therapeutics Consortium (TTC), a public-private partnership (PPP) led by the Critical Path Institute (C-Path), recently published a whitepaper titled "The Importance of Drug Safety and Tolerability in the Development of New Immunosuppressive Therapy for Transplant Recipients" by Stegall et al in the American Journal of Transplantation. As staff members of the Food and Drug Administration's (FDA), Center for Drug Evaluation and Research (CDER), Office of New Drugs and Office of Translational Science, and the Oncology Center of Excellence, we would like to provide our perspective on the TTCs efforts and the whitepaper.

Use of Mobile Devices to Measure Outcomes in Clinical Research, 2010-2016: A Systematic Literature Review.

Background: The use of mobile devices in clinical research has advanced substantially in recent years due to the rapid pace of technology development. With an overall aim of informing the future use of mobile devices in interventional clinical research to measure primary outcomes, we conducted a systematic review of the use of and clinical outcomes measured by mobile devices (mobile outcomes) in observational and interventional clinical research.

Method: We conducted a PubMed search using a range of search terms to retrieve peer-reviewed articles on clinical research published between January 2010 and May 2016 in which mobile devices were used to measure study outcomes.

Developing and Implementing Performance Outcome Assessments: Evidentiary, Methodologic, and Operational Considerations.

The use of performance outcome (PerfO) assessments to measure cognitive or physical function in drug trials presents several challenges for both sponsors and regulators, owing in part to a relative lack of scientific guidance on their development, implementation, and interpretation. In December 2016, the Duke-Margolis Center for Health Policy convened a 2-day workshop to explore the evidentiary, methodologic, and operational challenges associated with PerfO measures, and to identify potential paths to addressing these challenges. This paper presents both a summary of the discussion as well as additional input from a working group of experts from FDA, industry, academia, and public-private consortia.

Use of PRO Measures to Inform Tolerability in Oncology Trials: Implications for Clinical Review, IND Safety Reporting, and Clinical Site Inspections.

Cancer therapeutics frequently lead to symptomatic adverse events (AE) that can affect treatment tolerability. The NCI has developed the Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE) to assess symptomatic AEs by direct patient self-report. Although longitudinal assessment of patient-reported symptomatic AEs holds promise to better inform treatment tolerability, using patient-reported outcome (PRO) measures to assess symptomatic AEs has raised several regulatory and good clinical practice issues among those who conduct cancer clinical trials.

Development of a harmonized patient-reported outcome questionnaire to assess myelofibrosis symptoms in clinical trials.

Along with reducing spleen size, relieving symptom severity is a key objective of the treatment of myelofibrosis (MF). Several questionnaires have been developed for patient self-report of MF symptoms in clinical trials and each includes unique instructions, items, and/or response scales. This variability in questionnaire content increases uncertainty; it is unclear which questionnaire is the most appropriate for assessing MF symptoms and it makes comparisons across trials difficult.

U.S. Food and Drug Administration Approval: Cabozantinib for the Treatment of Advanced Renal Cell Carcinoma.

On April 25, 2016, the FDA approved cabozantinib (Cabometyx; Exelixis, Inc.) for the treatment of advanced renal cell carcinoma (RCC) in patients who have received prior antiangiogenic therapy. The approval was based on data from one randomized, open-label, multicenter study in which patients with RCC who had received prior antiangiogenic therapy were treated with either cabozantinib 60 mg orally once daily (n = 330) or everolimus 10 mg orally once daily (n = 328).

Patient-Reported Outcomes in Glomerular Disease.

Incorporation of the patient perspective into research and clinical practice will enrich our understanding of the status and management of patients with glomerular disease and may result in therapies that better address patient needs. In recent years, the importance of the patient experience of glomerular disease has become clear, and significant efforts have been undertaken to systematically capture and describe the patient's disease experience. Patient-reported outcome instruments provide a means to assess the patient's experience in a quantitative manner, thus enabling for comparisons within and between patients.

Clinical outcome assessments in neuro-oncology: a regulatory perspective.

Overall survival, progression-free survival, and to a lesser extent objective response rate, have long been the most widely accepted endpoints used to evaluate clinical benefit in oncology trials. More recently, clinical outcome assessments (COAs) that measure the impact of disease and treatment on patients' symptoms and function have been recognized as having potential to be an integral component of the risk/benefit analysis of new therapies. Although COAs have been used to evaluate cognitive and physical functioning in neurological diseases, assessing patient-centered outcomes in individuals with malignant brain tumors presents unique challenges.

Focusing on Core Patient-Reported Outcomes in Cancer Clinical Trials: Symptomatic Adverse Events, Physical Function, and Disease-Related Symptoms.

Cancer clinical trials have relied on overall survival and measures of tumor growth or reduction to assess the efficacy of a drug. However, benefits are often accompanied by significant symptomatic toxicities. The degree to which a therapy improves disease symptoms and introduces symptomatic toxicity affects how patients function in their daily lives.

Patient-Reported Outcomes in Cancer Drug Development and US Regulatory Review: Perspectives From Industry, the Food and Drug Administration, and the Patient.

Data reported directly by patients about how they feel and function are rarely included in oncology drug labeling in the United States, in contrast to Europe and to nononcology labeling in the United States, where this practice is more common. Multiple barriers exist, including challenges unique to oncology trials, and industry's concerns regarding cost, logistical complexities, and the Food and Drug Administration's (FDA's) rigorous application of its 2009 guidance on the use of patient-reported outcome (PRO) measures. A panel consisting of representatives of industry, FDA, the PRO Consortium, clinicians, and patients was assembled at a 2014 workshop cosponsored by FDA to identify practical recommendations for overcoming these barriers.

Well-defined and reliable clinical outcome assessments for pediatric Crohn disease: a critical need for drug development.

Objectives: The aim of the present study was to identify areas for further development of clinical outcome assessment (COA) in pediatric Crohn disease (CD).

Methods: The study analyzed the measurement properties of all existing COA tools for pediatric CD in literature and published registration trials of approved drugs for pediatric CD based on criteria described in Food and Drug Administration guidance for patient-reported outcome (PRO) development.

Results: The Pediatric Crohn's Disease Activity Index (PCDAI) and its derivatives (abbreviated, short, modified, and weighted PCDAIs) were reviewed.

Instruments to Identify Prescription Medication Misuse, Abuse, and Related Events in Clinical Trials: An ACTTION Systematic Review.

Unlabelled: Measurement of inappropriate medication use events (eg, abuse or misuse) in clinical trials is important in characterizing a medication's abuse potential. However, no gold standard assessment of inappropriate use events in clinical trials has been identified. In this systematic review, we examine the measurement properties (ie, content validity, cross-sectional reliability and construct validity, longitudinal construct validity, ability to detect change, and responder definitions) of instruments assessing inappropriate use of opioid and nonopioid prescription medications to identify any that meet U.

Can we use social media to support content validity of patient-reported outcome instruments in medical product development?

We report a panel designed to open a dialog between pharmaceutical sponsors, regulatory reviewers, and other stakeholders regarding the use of social media to collect data to support the content validity of patient-reported outcome instruments in the context of medical product labeling. Multiple stakeholder perspectives were brought together to better understand the issues encountered in pursuing social media as a form of data collection to support content validity. Presenters represented a pharmaceutical sponsor of clinical trials, a regulatory reviewer from the Food and Drug Administration, and an online data platform provider.

Steps toward harmonization for clinical development of medicines in pediatric ulcerative colitis-a global scientific discussion, part 1: efficacy endpoints and disease outcome assessments.

Objectives: There is a pressing need for drug development in pediatric ulcerative colitis (UC). Lack of scientific consensus on efficacy endpoints and disease outcome assessments presents a hurdle for global drug development in pediatric UC. Scientists from 4 regulatory agencies convened an International Inflammatory Bowel Disease Working Group (i-IBD Working Group) to harmonize present thinking about various aspects of drug development in pediatric UC globally.
