Critical Comments by Food and Drug Administration Reviewers on Patient-Reported Outcomes in Food and Drug Administration Regulatory Submissions (2018-2021).

OBJECTIVES: This article examined the inclusion of patient-reported outcome (PRO) data in new drug applications (NDAs) submitted to the Food and Drug Administration (FDA) and approved from 2018 to 2021. The importance of assessing PROs, which capture patients' perspectives on the disease and treatment experience, has been underscored by many stakeholders, including regulatory authorities. Despite the increasing inclusion of PRO assessments in registration trials, inclusion of language related to PRO results in approved product labeling varies widely. METHODS: This study examined FDA submission packages for NDAs approved by the FDA from 2018 to 2021 to identify critical reviewer comments related to PROs. Comments were identified and categorized by the type of criticism. Reviewers considered both oncology and nononcology indications. RESULTS: Assessment of PROs was included in 66.2% of the 210 submissions reviewed. Critical comments were identified in 45.3% of these applications; comments most commonly related to statistical analysis considerations, fit for purpose, and study design. Other categories of critical comment included data quality, lack of treatment benefit, administrative considerations, and miscellaneous issues. Differences were observed between oncology and nononcology NDAs with regard to the number and type of comments included in each of these categories. The findings highlight the importance of planning statistical analyses, establishing content validity, carefully considering study design, maximizing data quality, and demonstrating treatment benefit, among other issues. CONCLUSIONS: Overall, this study offers insight into the landscape of PRO data included in recently approved NDAs, along with recommendations for improving the quality and reporting of PROs in clinical trials.

Assessment of Patient-Reported Outcomes in Industry-Sponsored Phase I Oncology Studies: Considerations for Translating Theory Into Practice.

An increasing interest in the identification of optimal dosage for oncology therapies has prompted key opinion leaders and regulators to encourage the integration of patient-reported outcome (PRO) assessments in phase I oncology clinical trials. Although the potential benefits of assessing PROs in early-phase studies have been acknowledged, the difficulties that arise from such a radical shift have been largely overlooked in the public discussion. In this commentary, the authors provide insight into the challenges that industry sponsors face in integrating PRO assessments into phase I oncology trials, with the ultimate goal of facilitating conversations that may help to resolve some of these issues.

A Review of Labeling Based on Patient-Reported Outcome Endpoints for New Oncology Drugs Approved by the European Medicines Agency (2017-2021).

OBJECTIVE: A review of new oncology indications approved by the European Medicines Agency (EMA) for 2012-2016 showed that 33% of new drugs had labeling based on patient-reported outcomes (PROs). We reviewed labeling text based on PRO endpoints for new oncology indications approved during 2017-2021. METHODS: New oncology drugs approved by EMA to treat indications of cancers during 2017-2021 were identified from the EMA website. PRO-related language reported in EMA summaries of product characteristics (SmPCs) were summarized and compared with similar findings reported for oncology indications approved during 2012-2016. RESULTS: Review documents by the EMA during 2017-2021 were available for 49 new oncology drugs for 70 cancer indications. Submissions for 52 (74.3%) of the 70 indications included PRO data for EMA review. Of all submissions, 14 (20.0%) approvals contained PRO-related language in the SmPC. Broad concepts such as health-related quality of life were most common and found in 8 of 14 (57.1%) PRO-related labels. CONCLUSION: PRO-related language appeared in SmPCs for 20% of all indications of new oncology drugs approved by EMA during 2017-2021 compared with approximately 33% of EMA approvals during 2012-2016. PRO-related labeling during the same periods showed a greater decline (from 47% to 27%) for indications of new oncology drugs that also included PRO data. One possible reason for this decline may be the increase in open-label studies from 62% between 2012 and 2016 to approximately 79% between 2017 and 2021.

A Review of Patient-Reported Outcome Labeling of FDA-Approved New Drugs (2016-2020): Counts, Categories, and Comprehensibility.

OBJECTIVES: A review of new drug approvals (NDAs) by the US Food and Drug Administration (FDA) for 2006 to 2015 showed that approximately 20% of new drugs had labeling based on patient-reported outcomes (PROs). The purpose of this study was to review labeling text based on PRO endpoints for NDAs from 2016 to 2020, with a special focus on the comprehensibility of such statements when included. METHODS: We reviewed drug approval reports on the Drugs@FDA web page of the FDA website to determine the number of NDAs from 2016 to 2020. For all identified NDAs, drug approval package and product labels were reviewed. NDAs from 2016 to 2020 were grouped by disease category as per International Classification of Diseases 10th Revision. Data were summarized for diseases that traditionally rely on PROs for evaluating treatment benefit (PRO dependent) and for diseases that traditionally do not rely on PROs (non-PRO dependent). Results were compared with NDAs from 2006 to 2010. RESULTS: NDAs amounting to 228 were identified from 2016 to 2020, 26.3% of which had labeling statements based on PRO endpoints. From 2006 to 2015 and from 2016 to 2020, PRO labeling statements were included in 46.5% (46 of 99) and 50.0% (47 of 94), respectively, of NDAs for PRO-dependent new molecular entities and in 6.0% (12 of 199) and 9.7% (13 of 199), respectively, of NDAs for non-PRO-dependent new molecular entities. Comprehensibility of labeling statements based on PRO endpoints was judged to be complex in 56.7% of product labels. CONCLUSIONS: The increase in labeling text based on PRO endpoints in product labels is encouraging. However, there is room for improvement on the comprehensibility of labeling statements based on PRO endpoints.

Ethical Considerations for the Inclusion of Patient-Reported Outcomes in Clinical Research: The PRO Ethics Guidelines.

Importance: Patient-reported outcomes (PROs) can inform health care decisions, regulatory decisions, and health care policy. They also can be used for audit/benchmarking and monitoring symptoms to provide timely care tailored to individual needs. However, several ethical issues have been raised in relation to PRO use. Objective: To develop international, consensus-based, PRO-specific ethical guidelines for clinical research. Evidence Review: The PRO ethics guidelines were developed following the Enhancing the Quality and Transparency of Health Research (EQUATOR) Network's guideline development framework. This included a systematic review of the ethical implications of PROs in clinical research. The databases MEDLINE (Ovid), Embase, AMED, and CINAHL were searched from inception until March 2020. The keywords patient reported outcome* and ethic* were used to search the databases. Two reviewers independently conducted title and abstract screening before full-text screening to determine eligibility. The review was supplemented by the SPIRIT-PRO Extension recommendations for trial protocol. Subsequently, a 2-round international Delphi process (n = 96 participants; May and August 2021) and a consensus meeting (n = 25 international participants; October 2021) were held. Prior to voting, consensus meeting participants were provided with a summary of the Delphi process results and information on whether the items aligned with existing ethical guidance. Findings: Twenty-three items were considered in the first round of the Delphi process: 6 relevant candidate items from the systematic review and 17 additional items drawn from the SPIRIT-PRO Extension. Ninety-six international participants voted on the relevant importance of each item for inclusion in ethical guidelines and 12 additional items were recommended for inclusion in round 2 of the Delphi (35 items in total). Fourteen items were recommended for inclusion at the consensus meeting (n = 25 participants). The final wording of the PRO ethical guidelines was agreed on by consensus meeting participants with input from 6 additional individuals. Included items focused on PRO-specific ethical issues relating to research rationale, objectives, eligibility requirements, PRO concepts and domains, PRO assessment schedules, sample size, PRO data monitoring, barriers to PRO completion, participant acceptability and burden, administration of PRO questionnaires for participants who are unable to self-report PRO data, input on PRO strategy by patient partners or members of the public, avoiding missing data, and dissemination plans. Conclusions and Relevance: The PRO ethics guidelines provide recommendations for ethical issues that should be addressed in PRO clinical research. Addressing ethical issues of PRO clinical research has the potential to ensure high-quality PRO data while minimizing participant risk, burden, and harm and protecting participant and researcher welfare.

Use of Patient and Investigator Global Impression Scales: A Review of Food and Drug Administration-Approved Labeling, 2009 to 2019.

OBJECTIVE: Identify disease categories in which single-item global impression (GI) scales were included in product labeling of new drugs approved by the US Food and Drug Administration (FDA) in January 2009-December 2019 and review the characteristics of GIs included in product labeling of new FDA-approved drugs (January 2017-December 2019). METHODS: FDA Clinical Outcome Assessment (COA) Compendium was reviewed for drug labels that included GIs for drugs approved in 2009-2016. The indication, year of approval, ICD-10 code, and GI respondent were noted. A manual review of labels of FDA-approved drugs (2017-2019) was undertaken to identify GIs included in the labels. Corresponding drug approval packages were reviewed to identify details of any regulatory reviewer comments related to GIs. GI characteristics were noted from the drug label or the review documents, including the respondent, type of measure (static or dynamic), item wording, concept assessed, and response options. RESULTS: Product labeling containing GIs was most common in diseases related to the skin, nervous system, behavioral disorders, and the musculoskeletal system. GIs were included in 30/77 (39.0%) drug labels in the four disease categories. CONCLUSION: In the past 10 years, GIs have been included as endpoint measures in confirmatory clinical trials and have generated evidence of treatment benefit in diseases related to the skin, nervous system, behavioral disorders, and the musculoskeletal system. GIs frequently provide important insights into the patient experience. Before GIs are included in clinical trials to assess treatment benefit, it is important to ensure that they are valid, reliable, and responsive.

Quality of life is maintained with ixazomib maintenance in post-transplant newly diagnosed multiple myeloma: The TOURMALINE-MM3 trial.

OBJECTIVES: Health-related quality of life (HRQoL) is particularly important during maintenance therapy (MT) in newly diagnosed multiple myeloma post-transplant, when disease symptoms are limited. METHODS: We assessed HRQoL in patients randomised to 26 cycles of MT (ixazomib vs placebo) in TOURMALINE-MM3 (NCT02181413). RESULTS: The characteristics at study entry were well-balanced between ixazomib (n = 386) and placebo (n = 251) arms. At study entry, EORTC QLQ-C30 and MY20 scores were high for functional scales and low for symptom scales and were comparable with those of the general population. Changes in subscale scores across intervals, analysed over 30 four-week intervals using a linear mixed-effects model, were generally small and similar between arms for the EORTC QLQ-C30 Global Health Status/QoL, Physical Functioning, and Pain subscales and EORTC QLQ-MY20 Disease Symptoms subscale and Peripheral Neuropathy item. EORTC QLQ-C30 Nausea/Vomiting and Diarrhoea subscales were consistently worse for ixazomib than for placebo, in line with the ixazomib toxicity profile. Even when least-squares mean differences between arms were statistically significant, none reached the established minimal important clinical difference of 10 in multiple myeloma. CONCLUSIONS: In addition to improvement in progression-free survival with ixazomib, HRQoL was maintained in both arms. Active treatment with ixazomib did not have an adverse impact on HRQoL.

A Review of Patient-Reported Outcomes Labeling for Oncology Drugs Approved by the FDA and the EMA (2012-2016).

OBJECTIVES: To compare US Food and Drug Administration (FDA) and European Medicines Agency (EMA) labeling for evidence based on patient-reported outcomes (PROs) of new oncology treatments approved by both agencies. METHODS: Oncology drugs and indications approved between 2012 and 2016 by both the FDA and the EMA were identified. PRO-related language and analysis reported in US product labels and drug approval packages and EMA summaries of product characteristics were compared for each indication. RESULTS: In total, 49 oncology drugs were approved for a total of 64 indications. Of the 64 indications, 45 (70.3%) included PRO data in either regulatory submission. No FDA PRO labeling was identified. PRO language was included in the summary of product characteristics for 21 (46.7%) of 45 indications. European Organisation for Research and Treatment of Cancer and Functional Assessment of Cancer Therapy measures were used frequently in submissions. FDA's comments suggest that aspects of study design (eg, open labels) or the validity of PRO measures was the primary reason for the lack of labeling based on PRO endpoints. Both agencies identified missing PRO data as problematic for interpretation. CONCLUSIONS: During this time period, the FDA and the EMA used different evidentiary standards to assess PRO data from oncology studies, with the EMA more likely to accept data from open-label studies and broad concepts such as health-related quality of life. An understanding of the key differences between the agencies may guide sponsor PRO strategy when pursuing labeling. Patient-focused proximal concepts are more likely than distal concepts to receive positive reviews.

A Review of Patient-Reported Outcome Labeling in the United States (2011-2015).

BACKGROUND: A review of new drug approvals (NDAs) by the Food and Drug Administration (FDA) for 2006 to 2010 showed that 24.1% of new drugs had patient-reported outcome (PRO) labeling. OBJECTIVES: To review PRO labeling for NDAs for 2011 to 2015 and to compare key findings reported previously. METHODS: A review of the FDA drug approval reports for NDAs was conducted using the FDA Web site to determine the number of NDAs for the period 2011 to 2015. For all identified NDAs, drug approval package and product labeling were reviewed to identify PRO end-point status and PRO labeling. NDAs for the period 2006 to 2015 were grouped by disease category as per the International Classification of Diseases, Tenth Revision. Data were summarized for all NDAs and for approvals in diseases that traditionally rely on PROs for evaluating treatment benefit (PRO-dependent). Results were compared with NDAs for the period 2006 to 2010. RESULTS: In the period 2011 to 2015, 16.5% of the 182 NDAs had PRO labeling. For PRO-dependent NDAs, this figure was 46.9% and 46.0% for the period 2006 to 1010 and the period 2011 to 2015, respectively. Most of the PRO labeling for the period 2011 to 2015 was based on primary end points (76.7%). Almost all PRO labeling was for concepts proximal to the disease. CONCLUSIONS: There is potential for increased PRO labeling, especially for drug approvals in diseases that traditionally rely on PROs for evaluating treatment benefit to satisfy regulatory needs. Less PRO labeling based on secondary end points may be indicative of drug manufacturers' reluctance to aid and enhance the value propositions of their products to all stakeholders, including patients.

Secukinumab sustains early patient-reported outcome benefits through 1 year: Results from 2 phase III randomized placebo-controlled clinical trials comparing secukinumab with etanercept.

BACKGROUND: Psoriasis is a chronic condition with negative impact on patients' quality of life that most often requires lifelong effective and safe treatment. OBJECTIVE: This analysis focused on the effect of secukinumab treatment on patient-reported health-related quality of life as assessed by the Dermatology Life Quality Index (DLQI) in patients with moderate to severe psoriasis. METHODS: The proportion of subjects achieving DLQI score 0/1 response at week 24, time to DLQI score 0/1 response, and sustained DLQI score 0/1 response up to week 52 were compared between secukinumab and etanercept. RESULTS: Of 1470 subjects, 1144 received secukinumab and 326 received etanercept. DLQI score 0/1 response rates were significantly higher for secukinumab than for etanercept at week 24. The median time to DLQI score 0/1 response was significantly shorter for secukinumab versus etanercept (12 vs 24 weeks; P < .01). The majority of secukinumab-treated subjects achieved DLQI score 0/1 response at week 24 and sustained it through week 52 along with a 90% to 100% reduction in the Psoriasis Area and Severity Index total score response. LIMITATIONS: Placebo comparisons are limited during the maintenance period because of rerandomization at week 12. CONCLUSION: Secukinumab treatment provided faster and greater sustained improvements in quality of life than etanercept over 52 weeks, consistent with greater clinical response.

Development of the sporadic inclusion body myositis physical functioning assessment.

INTRODUCTION: Sporadic inclusion body myositis (sIBM) is a progressive idiopathic inflammatory myopathy characterized by atrophy and weakness of proximal and distal muscle groups that results in a loss of independence and the need for assistive devices and supportive care. To assess treatment benefit of new therapies, a patient-reported outcome measure of physical function was developed. METHODS: The tool was rigorously developed in accordance with the United States Food and Drug Administration (FDA) patient-reported outcomes (PRO) guidance. A single-visit, observational study was conducted. Standard qualitative analytical methods were employed to analyze interview data and generate questionnaire items. RESULTS: Twenty concept elicitation and 19 cognitive debriefing interviews were conducted, and 6 expert physicians were consulted. The tool consists of 11 items scored on a 0-10 numerical rating scale. Subjects completed the questionnaire utilizing either paper or electronic administration. CONCLUSION: We have developed a PRO tool in alignment with FDA PRO guidance for use in the functional assessment of treatment benefit in sIBM.

Psychometric validation of a patient-reported measure of physical functioning in sporadic inclusion body myositis.

INTRODUCTION: To assess self-reported physical functioning in patients with sporadic inclusion body myositis (sIBM), the sIBM Physical Functioning Assessment (sIFA) was developed. This research establishes the validity, reliability, and responsiveness of the sIFA in patients with sIBM. METHODS: Data from 3 small, noninterventional, observational studies were analyzed. Several measures of physical function were included to assess validity. Reliability (Cronbach alpha, test-retest intraclass correlations), construct validity (correlations, analyses of variance), and responsiveness (effect size estimates) were evaluated. RESULTS: Cronbach alphas (range = 0.86-0.91) and test-retest reliability (0.91) were highly satisfactory. Correlations with other measures provided evidence of convergent validity. sIBM patients able to walk without assistive devices scored significantly better on the sIFA (means = 36.0-47.05) than those who required power mobility or wheelchairs (means = 54.9-71.5), demonstrating the discriminating ability of the sIFA. Effect size estimates of responsiveness suggested mild functional progression. CONCLUSIONS: Psychometric analyses of the sIFA demonstrate satisfactory reliability, validity, and responsiveness. Muscle Nerve 54: 658-665, 2016.

Secukinumab treatment in rheumatoid arthritis is associated with incremental benefit in the clinical outcomes and HRQoL improvements that exceed minimally important thresholds.

BACKGROUND: The primary aim of rheumatoid arthritis (RA) treatment is to induce remission, the absence of disease activity. The objective of this study was to explore the association between clinical endpoints used to gauge RA treatment efficacy and patient-reported outcomes of health-related quality of life, fatigue, and physical function in RA patients treated with secukinumab in a phase 2 randomized controlled trial (RCT). METHOD: Adult RA patients (n = 237) with incomplete responses to methotrexate were randomized equally to receive monthly s.c. injections of secukinumab 25 mg, 75 mg, 150 mg, 300 mg or placebo. Clinical endpoints used in this study included the ACR response criteria and its components and simplified disease activity score. Patient-reported outcomes (PRO) included Health Assessment Questionnaire-Disability Index (HAQ-DI), Medical Outcomes Study Short Form-36 [SF-36] Survey, and Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-Fatigue). Patients were categorized into mutually exclusive groups according to the magnitude and direction of change from baseline to week 16 in each clinical endpoint. Definitions of minimal important differences [MID] in each clinical endpoint were used to categorize patients, as well as thresholds beyond MID. Mean changes from baseline to week 16 were computed for each PRO and analyses of variance to test the differences in PRO changes observed across groups of patients that differed in each clinical endpoint. Analyses were limited to patients randomized to secukinumab treatment. All dose groups were combined (n = 187). RESULTS: Mean changes from baseline in each PRO differed significantly across groups of patients in the expected direction. With few exceptions, there was considerable agreement between clinical endpoints and PROs concerning the magnitude of change defined as clinically meaningful. More importantly, results demonstrated that greater improvements in clinical endpoints were associated with incrementally better improvements in HRQoL, fatigue, and physical function. CONCLUSION: Results of this study show considerable agreement between minimal thresholds of improvement established for PROs and clinical outcome measures used in RA treatment studies and provide thresholds to be considered in gauging the importance of a treatment effect that goes beyond what is considered as minimally important for PRO measures.

Advancing patient-centric care: integrating patient reported outcomes for tolerability assessment in early phase clinical trials - insights from an expert virtual roundtable.

Early phase clinical trials provide an initial evaluation of therapies' risks and benefits to patients, including safety and tolerability, which typically relies on reporting outcomes by investigator and laboratory assessments. Use of patient-reported outcomes (PROs) to inform risks (tolerability) and benefits (improvement in disease symptoms) is more common in later than early phase trials. We convened a two-day expert roundtable covering: (1) the necessity and feasibility of a universal PRO core conceptual model for early phase trials; (2) the practical integration of PROs in early phase trials to inform tolerability assessment, guide dose decisions, or as real-time safety alerts to enhance investigator-reported adverse events. Participants (n = 22) included: patient advocates, regulators, clinicians, statisticians, pharmaceutical representatives, and PRO methodologists working across diverse clinical areas. In this manuscript, we report major recommendations resulting from the roundtable discussions corresponding to each theme. Additionally, we highlight priority areas necessitating further investigation.

Recommendations to address respondent burden associated with patient-reported outcome assessment.

Patient-reported outcomes (PROs) are increasingly used in healthcare research to provide evidence of the benefits and risks of interventions from the patient perspective and to inform regulatory decisions and health policy. The use of PROs in clinical practice can facilitate symptom monitoring, tailor care to individual needs, aid clinical decision-making and inform value-based healthcare initiatives. Despite their benefits, there are concerns that the potential burden on respondents may reduce their willingness to complete PROs, with potential impact on the completeness and quality of the data for decision-making. We therefore conducted an initial literature review to generate a list of candidate recommendations aimed at reducing respondent burden. This was followed by a two-stage Delphi survey by an international multi-stakeholder group. A consensus meeting was held to finalize the recommendations. The final consensus statement includes 19 recommendations to address PRO respondent burden in healthcare research and clinical practice. If implemented, these recommendations may reduce PRO respondent burden.

Assessment of PRO label claims granted by the FDA as compared to the EMA (2006-2010).

BACKGROUND: The US Food and Drug Administration (FDA) provides formal guidance for the use of patient-reported outcomes (PROs) in support of labeling claims, whereas the European Medicines Agency (EMA) offers insight in a reflection paper relating to health-related quality of life in lieu of formal guidance. OBJECTIVES: PRO label claims granted for new molecular entities and biologic license applications from 2006 through 2010 were reviewed to evaluate consistencies and discrepancies in PRO label claims granted by the FDA and the EMA and to highlight trends in the acceptance of PRO claims across agencies. METHODS: Products approved by both the FDA and the EMA were identified. By using US Drug Approval Packages and European Public Assessment Reports packages, any PRO label claims made for the same product by the same company were compared. RESULTS: Both agencies approved a total of 75 products. Of these, 35 (47%) had at least one EMA-granted PRO label claim compared with 14 (19%) by the FDA. Most FDA-grated claims focused on symptoms; however, EMA-granted claims were more likely to include higher order concepts. Few (~12%) were granted the same label claims. Despite this discordance between the two agencies, where PRO label claims were granted by both the FDA and the EMA, there was similarity in the type of label claim. CONCLUSIONS: The EMA is more likely than the FDA to grant PRO claims and for higher order constructs. On a macro level, there appears to be poor concordance between claims granted by both agencies. On close examination, however, there appears to be greater concordance than previously recognized, which may be instructive in formulating future PRO strategies. Further research to create strategic alignment across agencies may be beneficial.

Potential of patient-reported outcomes as nonprimary endpoints in clinical trials.

BACKGROUND: The purpose of this research was to fully explore the impact of endpoint type (primary vs. nonprimary) on decisions related to patient-reported outcome (PRO) labeling claims supported by PRO measures and to determine if nonprimary PRO endpoints are being fully optimized.This review examines the use of PROs as both primary and nonprimary endpoints in support of demonstration of treatment benefit of new molecular entities (NMEs) and biologic license applications (BLAs) in the United States in the years 2000 to 2012. METHODS: All NMEs and BLAs approved by the Food and Drug Administration (FDA) between January 2000 and June 2012 were identified using the FDA Drug Approval Reports Web page. Generic products granted tentative approvals were excluded. For all identified products, medical review sections from publicly available drug approval packages were reviewed to identify PRO endpoint status. Product labels (indication, clinical trials sections) were reviewed to determine the number and type of PRO claim. RESULTS: A total of 308 NMEs/BLAs were identified. Of these, 70 NMEs/BLAs (23%) were granted PRO claims. The majority of product claims were for disease- or condition-specific signs and symptoms. Of the 70 products with PRO claims, a PRO was a primary endpoint for the vast majority (57 [81%]). A total of 19 of the 70 products were granted a PRO claim based on a nonprimary endpoint. While nonprimary endpoints were used most often to support claims of improved signs or symptoms, nonprimary endpoints were much more likely to support claims of higher order impacts. CONCLUSIONS: Successful PRO labeling claims are typically based on primary endpoints assessing signs and symptoms. Based on this research, studies with PROs as primary endpoints are far more likely to facilitate positive regulatory review and acceptance of PROs in support of labeling claims. Although inclusion of PROs as nonprimary endpoints in clinical trials has its challenges, recent PRO labels granted by the FDA show that they can indeed be candidates for PRO labeling claims as long as they are supported by evidence.

A Review of Patient-Reported Outcome Considerations in Oncologic Drugs Advisory Committee Meetings (2016-2021).

PURPOSE: The purpose of this project was to gain insight into the role of patient-reported outcome (PRO) data in US Food and Drug Administration (FDA) Oncologic Drugs Advisory Committee (ODAC) reviews and recommendations by documenting PRO-related considerations that appear in transcripts of ODAC meetings over a 6-year period (2016-2021). METHODS: ODAC meeting transcripts were reviewed for any mention of PRO-related concepts. Meetings that reviewed biosimilars and meetings that discussed conceptual matters were excluded. For each identified transcript, the meeting date, brand and generic names of the drug, and indication were collected from the meeting minutes. Comments by ODAC members, FDA reviewers, and study sponsors on PRO data were captured during the review. Qualitative review of transcripts included both reading and searching for key terms, including PROs, quality of life, and health-related quality of life. Discussion of PRO-related topics was captured verbatim, organized thematically, and analyzed by two independent reviewers. RESULTS: Twenty-seven transcripts of reviews were identified for 2016-2021. Topics related to PROs were included in 12 of those 27 reviews. The ODAC was satisfied with PROs included in 2 of those 12 reviews. Reasons for dissatisfaction in 10 of the 12 reviews included key concepts not assessed (5/12), missing data (5/12), and disagreement with sponsors' interpretation (3/12). The ODAC also expressed dissatisfaction with the lack of PRO data in 6 of 15 reviews that did not include PROs. CONCLUSION: Less than half of ODAC reviews in 2016-2021 included PROs, and reviewers expressed frustration at the lack of PRO data. Even when included, evidence on the basis of PROs was rarely deemed adequate for benefit-risk assessments.

Quality of life improvements following one year of setmelanotide in children and adult patients with Bardet-Biedl syndrome: phase 3 trial results.

BACKGROUND: Bardet-Biedl syndrome is a rare genetic disease associated with hyperphagia and early-onset, severe obesity. There is limited evidence on how hyperphagia and obesity affect health-related quality of life in patients with Bardet-Biedl syndrome, and on how management of these symptoms may influence disease burden. This analysis evaluated changes in health-related quality of life in adults and children with Bardet-Biedl syndrome in a Phase 3 trial following 1 year of setmelanotide treatment (ClinicalTrials.gov identifier: NCT03746522). METHODS: Patients with Bardet-Biedl syndrome and obesity received 52 weeks of treatment with setmelanotide and completed various self-reported health-related quality of life measures. Patients aged < 18 years or their caregiver completed the Pediatric Quality of Life Inventory (PedsQL; meaningful improvement, 4.4-point change); adults aged ≥ 18 years completed the Impact of Weight on Quality of Life Questionnaire-Lite (IWQOL-Lite; meaningful improvement range, 7.7-12-point change). Descriptive outcomes were reported in patients with data both at active treatment baseline and after 52 weeks of treatment. RESULTS: Twenty patients (< 18 years, n = 9; ≥ 18 years, n = 11) reported health-related quality of life at baseline and 52 weeks. For children and adolescents, PedsQL score mean change from baseline after 52 weeks was + 11.2; all patients with PedsQL impairment at baseline (n = 4) experienced clinically meaningful improvement. In adults, IWQOL-Lite score mean change from baseline was + 12.0. Of adults with IWQOL-Lite impairment at baseline (n = 8), 62.5% experienced clinically meaningful improvement. In adults, IWQOL-Lite score was significantly correlated with changes in percent body weight (P = 0.0037) and body mass index (P = 0.0098). CONCLUSIONS: After 1 year of setmelanotide, patients reported clinically meaningful improvements across multiple health-related quality of life measures. This study highlights the need to address the impaired health-related quality of life in Bardet-Biedl syndrome, and supports utility of setmelanotide for reducing this burden.

A review of patient-reported outcome labels in the United States: 2006 to 2010.

OBJECTIVE: In 2004, Willke and colleagues reviewed the efficacy endpoints reported in the labels of new drugs approved in the United States from 1997 through 2002 to evaluate the use of patient-reported outcome (PRO) endpoints. Of the labels reviewed, 30% included PROs. Our study aimed to build on this work by describing the current state of PRO label claims granted for new molecular entities (and biologic license applications since February 2006 after the release of the US Food and Drug Administration (FDA) draft PRO guidance. METHODS: All new molecular entities and biologic license applications approved by the FDA from January 2006 through December 2010 were identified by using the Web page of the FDA Drug Approval Reports. For all identified products, drug approval packages and approved product labels were reviewed to identify PRO endpoint status and to determine the number and type of PRO claims. RESULTS: Of the 116 products identified, 28 (24%) were granted PRO claims; 24 (86%) were for symptoms, and, of these, 9 (38%) claims were pain related. Of the 28 products with PRO claims, a PRO was a primary endpoint for 20 (71%), all symptom related. CONCLUSIONS: The FDA continues to approve PRO claims, with 24% of new molecular entities and biologic license applications being granted. Successful PRO label claims over the past 5 years have generally supported treatment benefit for symptoms specified as primary endpoints.
