Assessing asthma symptoms in children: qualitative research supporting the development of the Pediatric Asthma Diary-Child (PAD-C) and Pediatric Asthma Diary-Observer (PAD-O).

Background: Pediatric asthma has been identified by regulators, clinicians, clinical trial sponsors, and caregivers as an area in need of novel fit-for-purpose clinical outcome assessments (COAs) developed in accordance with the U.S. Food and Drug Administration's (FDA's) regulatory guidance for evaluating clinical benefit in treatment trials.

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.

Updated Recommendations on Evidence Needed to Support Measurement Comparability Among Modes of Data Collection for Patient-Reported Outcome Measures: A Good Practices Report of an ISPOR Task Force.

The ISPOR Task Force on measurement comparability between modes of data collection for patient-reported outcome measures (PROMs) has updated the good practice recommendations from the 2009 ISPOR electronic patient-reported outcome and 2014 patient-reported outcome mixed modes Good Research Practices Task Force reports in light of accumulated evidence of measurement comparability among different modes of PROM data collection. Furthermore, with the increasing use of electronic formats of clinical outcome assessments in clinical trials and the US Food and Drug Administration's encouragement of electronic data collection, this new task force report provides stakeholders with best practice recommendations reflecting the current body of evidence and enables them to respond to future developments in research and technology. This task force recommends an evidence-based approach to determine whether new research is needed to evaluate measurement comparability for a given questionnaire or technology.

Best Practice Recommendations for Electronic Patient-Reported Outcome Dataset Structure and Standardization to Support Drug Development.

The electronic patient-reported outcome (ePRO) Dataset Structure and Standardization Project is a multistakeholder initiative formed by Critical Path Institute's PRO Consortium and Electronic Clinical Outcome Assessment (eCOA) Consortium to address issues related to ePRO dataset structure and standardization and to provide best practice recommendations for clinical trial sponsors and eCOA providers. Given the many benefits of utilizing electronic modes to capture PRO data, clinical trials are increasingly using these methods, yet there are challenges to using data generated by eCOA systems. Clinical Data Interchange Standards Consortium (CDISC) standards are used in clinical trials to ensure consistency in data collection, tabulation, and analysis and to facilitate regulatory submission.

Approaches to the Assessment of Clinical Benefit of Treatments for Conditions That Have Heterogeneous Symptoms and Impacts: Potential Applications in Rare Disease.

Objectives: Evaluating the clinical benefit of interventions for conditions with heterogeneous symptom and impact presentations is challenging. The same condition can present differently across and within individuals over time. This occurs frequently in rare diseases.

Comparability of a provisioned device versus bring your own device for completion of patient-reported outcome measures by participants with chronic obstructive pulmonary disease: quantitative study findings.

Objective: To quantitatively compare equivalence and compliance of patient-reported outcome (PRO) data collected via provisioned device (PD) versus bring your own device (BYOD).

Methods: Participants with stable chronic obstructive pulmonary disease (COPD) completed the EXAcerbations of Chronic Pulmonary Disease Tool (EXACT) daily and COPD Assessment Test™ (CAT) and Patient Global Impression of Severity (PGIS) of COPD weekly on either PD or BYOD for 15 days, then switched device types for 15 days. EXACT was scored using the Evaluating Respiratory Symptoms in COPD (E-RS: COPD) algorithm and equivalence assessed using intraclass correlation coefficients (ICCs) adjusting for cross-over sequence, period, and time.

Comparability of a provisioned device versus bring your own device for completion of patient-reported outcome measures by participants with chronic obstructive pulmonary disease: qualitative interview findings.

Background: There is interest in participants using their own smartphones or tablets ("bring your own device"; BYOD) to complete patient-reported outcome (PRO) measures in clinical studies. Our study aimed to qualitatively evaluate participants' experience using a provisioned device (PD) versus their own smartphone (BYOD) for this purpose.

Methods: Participants with chronic obstructive pulmonary disease (COPD) were recruited for this observational, cross-over study and completed PRO measures daily on one device type for 15 days, then switched to the other device type to complete the same measures for another 15 days.

Comparing patient global impression of severity and patient global impression of change to evaluate test-retest reliability of depression, non-small cell lung cancer, and asthma measures.

Purpose: Score reproducibility is an important measurement property of fit-for-purpose patient-reported outcome (PRO) measures. It is commonly assessed via test-retest reliability, and best evaluated with a stable participant sample, which can be challenging to identify in diseases with highly variable symptoms. To provide empirical evidence comparing the retrospective (patient global impression of change [PGIC]) and current state (patient global impression of severity [PGIS]) approaches to identifying a stable subgroup for test-retest analyses, 3 PRO Consortium working groups collected data using both items as anchor measures.

Non-Small Cell Lung Cancer Symptom Assessment Questionnaire (NSCLC-SAQ): Measurement Properties and Estimated Clinically Meaningful Thresholds From a Phase 3 Study.

Introduction: The NSCLC Symptom Assessment Questionnaire (NSCLC-SAQ) was developed to assess NSCLC symptom severity in accordance with Food and Drug Administration evidentiary expectations leading to Food and Drug Administration qualification in 2018. This study evaluated the NSCLC-SAQ's measurement properties within a clinical trial.

Methods: The KEYNOTE-598 phase 3 study of participants with stage IV metastatic NSCLC with programmed death-ligand 1 tumor proportion score greater than or equal to 50% was used to assess the NSCLC-SAQ's reliability, construct validity, responsiveness, and estimate clinically meaningful within-person change.

Recommendations for the Electronic Migration and Implementation of Clinician-Reported Outcome Assessments in Clinical Trials.

Objectives: Although best practices from electronic patient-reported outcome (PRO) measures are transferable, the migration of clinician-reported outcome (ClinRO) assessments to electronic modes requires recommendations that address their unique properties, such as the user (eg, clinician), and complexity associated with programming of clinical content. Faithful migration remains essential to ensuring that the content and psychometric properties of the original scale (ie, validated reference) are preserved, such that clinicians completing the ClinRO assessments interpret and respond to the items the same way regardless of data collection mode. The authors present a framework for how to "faithfully" migrate electronic ClinRO assessments for successful deployment in clinical trials.

Best Practice Recommendations: User Acceptance Testing for Systems Designed to Collect Clinical Outcome Assessment Data Electronically.

Implementing clinical outcome assessments electronically in clinical studies requires the sponsor and electronic clinical outcome assessment (eCOA) provider to work closely together to implement study-specific requirements and ensure consensus-defined best practices are followed. One of the most important steps is for sponsors to conduct user acceptance testing (UAT) using an eCOA system developed by the eCOA provider. UAT provides the clinical study team including sponsor or designee an opportunity to evaluate actual software performance and ensure that the sponsor's intended requirements were communicated clearly and accurately translated into the system design, and that the system conforms to a sponsor-approved requirements document based on the study protocol.

Asthma Daytime Symptom Diary (ADSD) and Asthma Nighttime Symptom Diary (ANSD): Measurement Properties of Novel Patient-Reported Symptom Measures.

Background: The Asthma Daytime Symptom Diary (ADSD) and the Asthma Nighttime Symptom Diary (ANSD) were developed to meet the need for standardized patient-reported measures of asthma symptoms to assess treatment trial outcomes in adults and adolescents.

Objective: To determine scoring and evaluate the measurement properties of the ADSD/ANSD.

Methods: Adolescents (12-17 years) and adults (18+ years) with asthma completed draft 8-item electronic versions of the ADSD/ANSD for 10 days alongside the Adult Asthma Symptom Daily Scales (AASDS) and a Patient Global Impression of Severity (PGIS).

Good practices for the translation, cultural adaptation, and linguistic validation of clinician-reported outcome, observer-reported outcome, and performance outcome measures.

Within current literature and practice, the category of patient-reported outcome (PRO) measures has been expanded into the broader category of clinical outcome assessments (COAs), which includes the subcategory of PRO, as well as clinician-reported outcome (ClinRO), observer-reported outcome (ObsRO), and performance outcome (PerfO) measure subcategories. However, despite this conceptual expansion, recommendations associated with translation, cultural adaptation, and linguistic validation of COAs remain focused on PRO measures, which has created a gap in specific process recommendations for the remaining types. This lack of recommendations has led to inconsistent approaches being implemented, leading to uncertainty in the scientific community regarding suitable methods.

Clinically Meaningful Change for Physical Performance: Perspectives of the ICFSR Task Force.

For clinical studies of sarcopenia and frailty, clinically meaningful outcome measures are needed to monitor disease progression, evaluate efficacy of interventions, and plan clinical trials. Physical performance measures including measures of gait speed and other aspects of mobility and strength have been used in many studies, although a definition of clinically meaningful change in performance has remained unclear. The International Conference on Frailty and Sarcopenia Research Task Force (ICFSR-TF), a group of academic and industry scientists investigating frailty and sarcopenia, met in Miami Beach, Florida, USA in February 2019 to explore approaches for establishing clinical meaningfulness in a manner aligned with regulatory authorities.

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).

Considerations for development of an evidence dossier to support the use of mobile sensor technology for clinical outcome assessments in clinical trials.

Background: Mobile sensors offer enormous potential for the collection of informative clinical endpoints in clinical trials to support regulatory decision making and product labelling. There are currently no specific guidelines on the information needed to enable regulators to review and accept proposed endpoints derived from mobile sensors for use in drug development trials.

Objective: The purpose of this working group report is to recommend the structure and content of an evidence dossier intended to support whether a clinical endpoint derived from mobile sensor data is fit-for-purpose for use in regulatory submissions for drug approvals.

Development and Validation of the FSIQ-RMS: A New Patient-Reported Questionnaire to Assess Symptoms and Impacts of Fatigue in Relapsing Multiple Sclerosis.

Objectives: A new patient-reported outcome (PRO) instrument to measure fatigue symptoms and impacts in relapsing multiple sclerosis (RMS) was developed in a qualitative stage, followed by psychometric validation and migration from paper to an electronic format.

Methods: Adult patients with relapsing-remitting multiple sclerosis (RRMS) were interviewed to elicit fatigue-related symptoms and impacts. A draft questionnaire was debriefed in cognitive interviews with further RRMS patients, and revised.

The importance of drug safety and tolerability in the development of new immunosuppressive therapy for transplant recipients: The Transplant Therapeutics Consortium's position statement.

The Transplant Therapeutics Consortium (TTC) is a public-private partnership between the US Food and Drug Administration and the transplantation community including the transplantation societies and members of the biopharmaceutical industry. The TTC was formed to accelerate the process of developing new medical products for transplant patients. The initial goals of this collaboration are the following: (a) To define which aspects of the kidney transplant drug-development process have clear needs for improvement from an industry and regulatory perspective; (b) to define which of the unmet needs in the process could be positively impacted through the development of specific drug-development tools based on available data; and (c) to determine the most appropriate pathway to achieve regulatory acceptance of the proposed process-accelerating tools.

Assessing test-retest reliability of patient-reported outcome measures using intraclass correlation coefficients: recommendations for selecting and documenting the analytical formula.

Purpose: The US Food and Drug Administration (FDA) 2009 guidance for industry on patient-reported outcome (PRO) measures describes how the Agency evaluates the psychometric properties of measures intended to support medical product labeling claims. An important psychometric property is test-retest reliability. The guidance lists intraclass correlation coefficients (ICCs) and the assessment time period as key considerations for test-retest reliability evaluations.

Reflection paper on copyright, patient-reported outcome instruments and their translations.

With the growth of patient-reported outcome (PRO) measurement, questions arise regarding how copyright protection applies to PRO instruments in general and to their translations in particular. The main objectives of this reflection paper are: 1) to help authors of PRO instruments understand basic rules of intellectual property and copyright that protect the integrity of their instruments and derivatives; and 2) to provide recommendations to authors and users of PRO instruments to prevent misuse or abuse.National laws on intellectual property (IP) and the international Berne Convention fully apply to PRO instruments since they are creations of the mind.

Best Practices for Avoiding Paper Backup When Implementing Electronic Approaches to Patient-Reported Outcome Data Collection in Clinical Trials.

Electronic data capture is fast becoming the preferred method of collecting patient-reported outcome (PRO) data in clinical trials. Data collection can be site-based (clinical study site), and typically collected on a tablet, or field-based (subject's typical environment such as home, school, or workplace), and most often accomplished with handheld devices, such as a smartphone. While site and study subject compliance with protocol-specific data collection procedures using these devices is critical to trial success, so is the robustness of the device hardware and the software these devices use to capture the trial data.

Training on the Use of Technology to Collect Patient-Reported Outcome Data Electronically in Clinical Trials: Best Practice Recommendations from the ePRO Consortium.

Electronic capture of patient-reported outcome (PRO) data has many advantages over paper-based data collection. Regulatory agencies have consistently supported the use of electronic PRO (ePRO) data capture and recommended participant and site staff training on the correct use of electronic data capture systems. The objective of this paper is to outline best practice recommendations for training end users, including site staff and study participants, on the use of ePRO technology in clinical trials to enable consistent, accurate, and complete data collection.
