RESUMEN
OBJECTIVES: This study assessed the content validity of generic and condition-specific preference-based measures (PBMs) with patients treated for cancer, evaluated against 10 Consensus-Based Standards for the Selection of Health Measurement Instruments criteria for good content validity, to best inform measurement strategies regarding the use of PBMs in oncology development programs and real-world applications. METHODS: Individual, semistructured interviews were conducted with patients who received drug treatment for cancer in the United Kingdom (n = 47) and the United States (n = 49). During the interview, patients completed 3 generic PBMs (EQ-5D-5L, EuroQol Health and Wellbeing measure-Short Form, Château Santé Base) and 2 condition-specific PBMs (Quality of Life Utility-Core 10 Dimension, Functional Assessment of Cancer Therapy Eight Dimension [FACT-8D]). Interviews were conducted via teleconference, audio recorded, and transcribed verbatim. Transcripts were coded using thematic and content analysis methods. RESULTS: Condition-specific measures were evaluated as having better relevancy than generic PBMs. Overall, the FACT-8D was evaluated as holding the best content validity in terms of relevancy, and the EuroQol Health and Wellbeing measure-Short Form received the most favorable evaluation of relevancy for generic PBMs. All measures demonstrated comparable comprehensiveness, with all suggested by patients to be missing concepts. The EQ-5D-5L was evaluated best in terms of comprehensibility. This was followed by the Quality of Life Utility-Core 10 Dimension and FACT-8D; both received similar evaluations. CONCLUSIONS: All measures were generally seen by patients as adequate in capturing appropriate aspects of health-related quality of life for measuring cancer outcomes, although together condition-specific measures were evaluated as having better relevancy than generic PBMs. Further health-related quality of life instrument development is encouraged, particularly with regard to the longer-term detrimental impacts of cancer and treatment side effects. Other developments could include new cancer-specific tools inclusive of conventional health items, treatment impacts, and psychological items.

OBJECTIVES: Time trade-off (TTO) and discrete choice experiment (DCE) preference-elicitation techniques can be administered using face-to-face interviews (F2F), unassisted online (UO) surveys, or remote-assisted (RA) interviews. The objective of this study was to explore how the mode of administration affects the quality and reliability of preference-elicitation data. METHODS: EQ-5D-5L health states were valued using composite TTO (cTTO) and DCE approaches by the UK general population. Participants were allocated to 1 of 2 study groups. Group A completed both F2F and UO surveys (n = 271), and group B completed both RA and UO surveys (n = 223). The feasibility of survey completion and the reliability and face-validity of data collected were compared across all modes of administration. RESULTS: Fewer participants reported receiving sufficient guidance on the cTTO tasks during the UO survey compared with the 2 assisted modes. Participants across all modes typically reported receiving sufficient guidance on the DCE tasks. cTTO data were less reliable from the UO survey compared with both assisted modes, but there were no differences in DCE data reliability. cTTO data from all modes demonstrated face-validity; however, the UO survey produced higher utilities for moderate and severe health states than both assisted modes. Both F2F and RA modes provided comparably reliable data. CONCLUSIONS: The reliability of DCE data is not affected by the mode of administration. Interviewer-assisted modes of administration (F2F or RA) yield more reliable cTTO data than unassisted surveys. Both F2F and RA surveys produced similar-quality data.

OBJECTIVES: This literature review provides an overview of meaningful change thresholds for the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (QLQ-C30) and the Functional Assessment of Cancer Therapy - General (FACT-G) used across hematological cancers and solid tumors (melanoma, lung, bladder, and prostate). METHODS: Embase, MEDLINE, and PubMed were searched to identify relevant oncology publications from 2016 to 2021. Label claims from the US Food and Drug Administration and the European Medicines Agency for 7 recently approved drugs (pembrolizumab, atezolizumab, glasdegib, gilteritinib, tisagenlecleucel, axicabtagene ciloleucel, and daratumumab plus hyaluronidase-fihj) were reviewed. RESULTS: Publications providing guidance on meaningful change thresholds for the QLQ-C30 displayed a growing trend away from broad "legacy" thresholds of 10 points for all QLQ-C30 scales), toward deriving "contemporary" thresholds (eg, subscale specific, population specific). Contemporary publications generally provide guidance on selecting thresholds for specific scales that account for improved or worsening thresholds (eg, QLQ-C30 subscales). This trend was not clear for FACT-G, with less new guidance available. Most clinical trials used in regulatory label submissions have used thresholds of 10 points for the QLQ-C30 subscales and 3 to 7 points for the FACT-G total score. Despite the availability of more recent guidelines, contemporary meaningful change thresholds seem slow to emerge in the published literature and regulatory labels. CONCLUSIONS: Trialists should consider using contemporary thresholds, rather than legacy thresholds, for QLQ-C30 endpoints. Thresholds derived for a similar patient-population should be used where available. Further work is required to provide these across a broader range of cancer sites.

OBJECTIVES: Estimates of minimally important differences (MID) can assist interpretation of data collected using patient-reported outcomes (PRO), but variability exists in the emphasis placed on MIDs in health technology assessment (HTA) guidelines. This study aimed to identify to what extent information on the MID of a commonly used PRO, the EQ-5D, is required and utilised by selected HTA agencies. METHODS: Technology appraisal (TA) documents from HTA agencies in England, France, Germany, and the US between 2019 and 2021 were reviewed to identify documents which discussed MID of EQ-5D data as a clinical outcome assessment (COA) endpoint. RESULTS: Of 151 TAs utilising EQ-5D as a COA endpoint, 58 (38%) discussed MID of EQ-5D data. Discussion of MID was most frequent in Germany, in 75% (n = 12/16) of Gemeinsamer Bundesausschuss (G-BA) and 44% (n = 34/78) of Institut für Qualität und Wirtschaftlichkeit im Gesundheitswesen, (IQWiG) TAs. MID was predominantly applied to the EQ-VAS (n = 50), most frequently using a threshold of > 7 or > 10 points (n = 13). G-BA and IQWiG frequently criticised MID analyses, particularly the sources of MID thresholds for the EQ-VAS, as they were perceived as being unsuitable for assessing the validity of MID. CONCLUSION: MID of the EQ-5D was not frequently discussed outside of Germany, and this did not appear to negatively impact decision-making of these HTA agencies. While MID thresholds were often applied to EQ-VAS data in German TAs, analyses were frequently rejected in benefit assessments due to concerns with their validity. Companies should pre-specify analyses of continuous data in statistical analysis plans to be considered for treatment benefit assessment in Germany.

PURPOSE: There are limited data on the impact of caregiving for patients with malignant pleural mesothelioma (MPM) on the caregiver. We aimed to identify the demographic characteristics of these caregivers, the caregiving activities they perform and how caregiving burden impacts their work productivity and overall activity. METHODS: This cross-sectional study collected data from caregivers of patients with MPM across France, Italy, Spain and the United Kingdom January-June 2019. Caregiver demographics, daily caregiving tasks and the impact of caregiving on physical health was collected via questionnaire. The Zarit Burden Interview (ZBI) was used to assess caregiver burden and the Work Productivity and Activity Impairment questionnaire (WPAI) assessed impairment at work and during daily activities. Analyses were descriptive. RESULTS: Overall, 291 caregivers provided data. Caregivers were mostly female (83%), living with the patient (82%) and their partner/spouse (71%). Caregivers provided over five hours of daily emotional/physical support to patients. ZBI scores indicated 74% of caregivers were at risk of developing depression. Employed caregivers had missed 12% of work in the past seven days, with considerable presenteeism (25%) and overall work impairment (33%) observed. Overall, the mean activity impairment was 40%. CONCLUSION: Caregivers provide essential care for those with MPM. We show caregiving for patients with MPM involves a range of burdensome tasks that impact caregivers' emotional health and work reflected in ZBI and WPAI scores. Innovations in the management of MPM must account for how caregivers may be impacted and can be supported to carry out this important role.

BACKGROUND: Malignant pleural mesothelioma (MPM) is an aggressive and rare tumour with poor prognosis. Most patients are diagnosed with advanced disease and there is a paucity of data on the humanistic burden of MPM in terms of impact on health-related quality of life (HRQoL) and activity. This study examined real-world treatment patterns and humanistic disease burden of MPM in Europe. METHODS: Physicians abstracted demographic/clinical characteristics and treatment data from MPM-patient medical records; MPM patients self-completed a questionnaire including symptoms, 3-level-EQ-5D questionnaire and Visual Analogue Scale (VAS), Lung Cancer Symptom Scale for Mesothelioma (LCSS-Meso), and Work Productivity and Activity Impairment (WPAI) questionnaire. RESULTS: Physicians (n = 171) abstracted data of 1390 patients; 767/1390 patients self-completed questionnaires. Patients were elderly with advanced, unresectable MPM. Treatment patterns followed guidelines with most (81%) patients receiving platinum+antifolate chemotherapy at first line (1 L). Maintenance treatment use was high (51.1%) despite no recommended maintenance therapies. Symptom burden was high and health states and HRQoL were poor at 1; declining further with progression. Overall mean (SD): LCSS-Average Symptom Burden Index score was 48.8 (19.3; n = 758); EQ-5D Utility Index score was 0.510 (0.349; n = 763); EQ-5D VAS score was 54.2 (20.3;n = 766); LCSS-3-Item Global Index score was 143.2 (64.5; n = 762); LCSS-normal activities score was 51.9 (24.6;n = 765); WPAI-activity impairment was 56.0% (23.2%; n = 737). CONCLUSION: The humanistic burden of MPM is high, despite treatments being prescribed as per available guidance. Treatments that delay progression and provide palliation of symptoms are most likely to improve/maintain HRQoL.

This article discusses a recent methodological change to assess the additional benefit of drug intervention by the German Federal Joint Committee (Gemeinsamer Bundesausschuss), a key stakeholder in EUnetHTA21 (European Network for Health Technology Assessment joint consortium for future EU HTA regulation), methodological workstream. The German Federal Joint Committee (Gemeinsamer Bundesausschuss) set a universal individual response threshold at ≥ 15% of the scale range of the measurement instrument, for all patient-reported outcomes, to achieve an additional benefit rating for a given pharmaceutical intervention. This approach is originally based on a corresponding recommendation from the Institute for Quality and Efficiency in Health Care. The merits of this approach are reviewed from various perspectives, including the evidence basis, statistical and psychometric considerations, and regulatory perspectives by the ISPOR Clinical Outcomes Assessment Special Interest Group's multistakeholder group of authors (academia, contract research organizations, and industry). Particular focus is placed on the patient perspective within the Institute for Quality and Efficiency in Health Care approach. The article development incorporated feedback from ISPOR members during well-attended ISPOR US and European conference presentations and 2 formal rounds of written review. The authors concluded that the ≥ 15% response threshold is incongruent with previously defined and scientifically established thresholds and is not well-suited for universal implementation. Further scientific evidence and discussion among all stakeholders are needed, especially should this universal rule be considered in the context of future joint clinical assessments of health technologies in the European Union scheduled from 2025 onward.

BACKGROUND: Although current therapy for patients with early-stage squamous cell carcinoma of the head and neck (SCCHN) is potentially curative, the recurrence rate is high. Patients with recurrent or metastatic (R/M) SCCHN have a poor prognosis and substantial disease burden, including impaired health-related quality of life (HRQoL), productivity loss and indirect costs, such as need for caregiver support. The aim of this study was to characterize the impact of R/M SCCHN and its first-line treatment on patient and caregiver quality of life, daily activities and work productivity using real-world evidence from Europe. METHODS: This was a multicentre retrospective study of patients with R/M SCCHN in France, Germany, Italy, Spain and the United Kingdom incorporating patient and caregiver surveys, and a physician-reported medical chart review, conducted between January and May 2019. Patients aged 18 or over with a physician confirmed diagnosis R/M SCCHN completed four validated measures of disease activity and its impact on quality of life and work productivity, while caregivers also completed questionnaire to assess the burden of providing care. Physicians provided data for clinical characteristics, patient management, testing history and treatment patterns. RESULTS: A total of 195 medical/clinical oncologists provided data for 937, predominantly male (72%) patients, with almost half of patients aged over 65 years. The most frequently reported symptoms were fatigue (43%), weight loss (40%), pain (35%) and difficulty swallowing (32%). The EXTREME regimen was the most common first line therapy in over half of patients, who reported moderate or extreme pain/discomfort, and anxiety/depression, and problems with self-care resulting in a diminished health status compared with the general population. Only 14% were employed with high absenteeism or presenteeism, and over half of patients had a caregiver for whom the burden of care was substantial. CONCLUSION: Our results provide real-world insight into the multi-faceted burden associated with R/M SCCHN. The combination of poor HRQoL and the impairment in daily activities, social life and employment illustrates the wider impact of R/M SCCHN on patients and their caregivers, and highlights a need for novel 1 L treatment regimens to improve the humanistic and productivity burdens of this cancer.

OBJECTIVES: There is growing interest in condition-specific preference measures, including the European Organisation for Research and Treatment of Cancer Quality of Life Utility Measure-Core 10 Dimensions (QLU-C10D). This research assessed the implications of using utility indices on the basis of the EQ-5D-3L, a mapping of EQ-5D-3L to the EQ-5D-5L, and the QLU-C10D, and compared their psychometric properties. METHODS: Data were taken from 8 phase 3 randomized controlled trials of nivolumab with or without ipilimumab for the treatment of solid tumors. Utilities for progression-related states were calculated using the UK and English value sets and incremental quality-adjusted life-years (QALYs) derived from established UK cost-effectiveness models. The psychometric properties of the utility indices were assessed using pooled trial data. RESULTS: Compared with the EQ-5D-3L index, the mapped EQ-5D-5L index yielded an average of 6% more and the QLU-C10D index an average of 2% fewer incremental QALYs for nivolumab versus comparators. All indices could differentiate between groups defined by performance status, cancer stage, or self-reported health status at baseline and detect meaningful changes in performance status, tumor response, health status, and quality of life over approximately 12 weeks of treatment. CONCLUSIONS: The lower QALY yield of the QLU-C10D was balanced by evidence of greater validity and responsiveness. Benefits gained from using the QLU-C10D may be apparent when treatments affect targeted symptoms and functional aspects, including sleep, bowel function, appetite, nausea, and fatigue. The observed differences in QALYs may not be sufficiently large to affect health technology assessment decisions.

BACKGROUND: Immune checkpoint inhibitors (ICIs) are increasingly used to treat several types of tumors. Impact of this emerging therapy on patients' health-related quality of life (HRQoL) is usually collected in clinical trials through standard questionnaires. However, this might not fully reflect HRQoL of patients under real-world conditions. In parallel, users' narratives from social media represent a potential new source of research concerning HRQoL. OBJECTIVE: The aim of this study is to assess and compare coverage of ICI-treated patients' HRQoL domains and subdomains in standard questionnaires from clinical trials and in real-world setting from social media posts. METHODS: A retrospective study was carried out by collecting social media posts in French language written by internet users mentioning their experiences with ICIs between January 2011 and August 2018. Automatic and manual extractions were implemented to create a corpus where domains and subdomains of HRQoL were classified. These annotations were compared with domains covered by 2 standard HRQoL questionnaires, the EORTC QLQ-C30 and the FACT-G. RESULTS: We identified 150 users who described their own experience with ICI (89/150, 59.3%) or that of their relative (61/150, 40.7%), with 137 users (91.3%) reporting at least one HRQoL domain in their social media posts. A total of 8 domains and 42 subdomains of HRQoL were identified: Global health (1 subdomain; 115 patients), Symptoms (13; 76), Emotional state (10; 49), Role (7; 22), Physical activity (4; 13), Professional situation (3; 9), Cognitive state (2; 2), and Social state (2; 2). The QLQ-C30 showed a wider global coverage of social media HRQoL subdomains than the FACT-G, 45% (19/42) and 29% (12/42), respectively. For both QLQ-C30 and FACT-G questionnaires, coverage rates were particularly suboptimal for Symptoms (68/123, 55.3% and 72/123, 58.5%, respectively), Emotional state (7/49, 14% and 24/49, 49%, respectively), and Role (17/22, 77% and 15/22, 68%, respectively). CONCLUSIONS: Many patients with cancer are using social media to share their experiences with immunotherapy. Collecting and analyzing their spontaneous narratives are helpful to capture and understand their HRQoL in real-world setting. New measures of HRQoL are needed to provide more in-depth evaluation of Symptoms, Emotional state, and Role among patients with cancer treated with immunotherapy.

BACKGROUND: Defining the transition from relapsing-remitting multiple sclerosis (RRMS) to secondary progressive multiple sclerosis (SPMS) can be challenging and delayed. A digital tool (MSProDiscuss) was developed to facilitate physician-patient discussion in evaluating early, subtle signs of multiple sclerosis (MS) disease progression representing this transition. OBJECTIVE: This study aimed to determine cut-off values and corresponding sensitivity and specificity for predefined scoring algorithms, with or without including Expanded Disability Status Scale (EDSS) scores, to differentiate between RRMS and SPMS patients and to evaluate psychometric properties. METHODS: Experienced neurologists completed the tool for patients with confirmed RRMS or SPMS and those suspected to be transitioning to SPMS. In addition to age and EDSS score, each patient's current disease status (disease activity, symptoms, and its impacts on daily life) was collected while completing the draft tool. Receiver operating characteristic (ROC) curves determined optimal cut-off values (sensitivity and specificity) for the classification of RRMS and SPMS. RESULTS: Twenty neurologists completed the draft tool for 198 patients. Mean scores for patients with RRMS (n=89), transitioning to SPMS (n=47), and SPMS (n=62) were 38.1 (SD 12.5), 55.2 (SD 11.1), and 69.6 (SD 12.0), respectively (P<.001, each between-groups comparison). Area under the ROC curve (AUC) including and excluding EDSS were for RRMS (including) AUC 0.91, 95% CI 0.87-0.95, RRMS (excluding) AUC 0.88, 95% CI 0.84-0.93, SPMS (including) AUC 0.91, 95% CI 0.86-0.95, and SPMS (excluding) AUC 0.86, 95% CI 0.81-0.91. In the algorithm with EDSS, the optimal cut-off values were ≤51.6 for RRMS patients (sensitivity=0.83; specificity=0.82) and ≥58.9 for SPMS patients (sensitivity=0.82; specificity=0.84). The optimal cut-offs without EDSS were ≤46.3 and ≥57.8 and resulted in similar high sensitivity and specificity (0.76-0.86). The draft tool showed excellent interrater reliability (intraclass correlation coefficient=.95). CONCLUSIONS: The MSProDiscuss tool differentiated RRMS patients from SPMS patients with high sensitivity and specificity. In clinical practice, it may be a useful tool to evaluate early, subtle signs of MS disease progression indicating the evolution of RRMS to SPMS. MSProDiscuss will help assess the current level of progression in an individual patient and facilitate a more informed physician-patient discussion.

BACKGROUND: A broad literature base exists for measuring medication adherence to monotherapeutic regimens, but publications are less extensive for measuring adherence to multiple medications. OBJECTIVES: To identify and characterize the multiple medication adherence (MMA) methods used in the literature. METHODS: A literature search was conducted using PubMed, PsycINFO, the International Pharmaceutical Abstracts, the Cumulative Index to Nursing and Allied Health Literature and the Cochrane Library databases on methods used to measure MMA published between January 1973 and May 2015. A two-step screening process was used; all abstracts were screened by pairs of researchers independently, followed by a full-text review identifying the method for calculating MMA. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed to conduct this systematic review. For studies that met the eligibility criteria, general study and adherence-specific characteristics and the number and type of MMA measurement methods were summarized. RESULTS: The 147 studies that were included originated from 32 countries, in 13 disease states. Of these studies, 26 used proportion of days covered, 23 used medication possession ratio, and 72 used self-reported questionnaires (e.g., the Morisky Scale) to assess MMA. About 50% of the studies included more than one method for measuring MMA, and different variations of medication possession ratio and proportion of days covered were used for measuring MMA. CONCLUSIONS: There appears to be no standardized method to measure MMA. With an increasing prevalence of polypharmacy, more efforts should be directed toward constructing robust measures suitable to evaluate adherence to complex regimens. Future research to understand the validity and reliability of MMA measures and their effects on objective clinical outcomes is also needed.

OBJECTIVES: Individuals with tuberous sclerosis complex (TSC) experience a wide range of health impacts, including epileptic seizures, negatively impacting their health-related quality of life (HRQoL). Health state utility values (HSUVs) are index values representing HRQoL and are used as key inputs for health economic analyses. Such data are currently very limited in the TSC population. The objective of this study was to generate HSUVs for TSC health states, defined by the number and type of seizures experienced in the previous week, and to compare with UK normative values. METHODS: This cross-sectional study involved 186 participants (individuals with TSCâ¯=â¯61, caregivers reporting for individuals with TSCâ¯=â¯125) from Europe and North America who completed a web-based survey. Participants completed the [EuroQol - 5 dimensions - 3 levels] (self-report version for individuals with TSC or proxy version 1 for caregivers). RESULTS: The mean age of individuals with TSC was 27.3â¯years (self-reported: 41.3â¯years, caregiver-reported: 20.5â¯years); 56% were males. Most individuals with TSC (71%) reported experiencing between one and ten seizures in the week prior to participating in the study. The most frequently reported type of seizure was focal: simple partial (50%). Across all participants (combined self-report and caregiver-report), the mean HSUV was 0.474 (95% confidence interval [CI]: 0.424-0.524), significantly lower than the UK norm (0.856, 95%CI: 0.848-0.864) [1]. Mean HSUV and HRQoL scores were consistently lower when reported by caregivers than when self-reported by individuals with TSC (HSUVâ¯=â¯0.351 vs. 0.727). This is in part because caregivers reported for individuals with TSC who experienced more frequent and severe seizures than those who were able to self-report. HSUVs incrementally decreased with the experience of more frequent (1-5 per week: HSUVâ¯=â¯0.666 vs. >20: HSUVâ¯=â¯0.290) and more severe seizures (focal: simple partial: HSUVâ¯=â¯0.450 vs. generalized: convulsive: HSUVâ¯=â¯0.194). CONCLUSIONS: The HRQoL and HSUV index scores indicate substantial impairment among individuals with TSC; HSUVs were shown to decrease considerably with increases in seizure frequency or seizure severity, indicating that more burdensome seizure health states are associated with poorer HRQoL.

BACKGROUND: Dravet Syndrome (DS) is a rare developmental and epileptic encephalopathy characterized by multiple seizures, frequently prolonged and treatment refractory, with significant developmental disabilities and behavioral and psychiatric disorders. Patients with DS require intensive support and supervision from a caregiver, impacting significantly on both patients' and caregivers' lives. This study aimed to identify core concepts to measure the impact on both patients and caregivers in future DS clinical trials. METHODS: Qualitative concept elicitation interviews were conducted with caregivers and healthcare professionals involved in caring for children with DS (aged 2-18years) in France to identify important concepts related to the global impact of DS. Interviews explored a range of concepts, including triggers, symptoms, impacts, and coping strategies, from which a conceptual model was developed. A Delphi consensus panel with eight international clinical experts aimed to identify important and relevant endpoints. RESULTS: Seizure was the most commonly reported symptom with DS further impacting children's cognitive and behavioral functioning. Caregivers identified impact concepts not reported by healthcare professionals. Both groups described additional impacts on wider family members and home modifications. Clinical experts agreed on the inclusion of five patient- and caregiver-relevant concepts for measurement in future DS clinical trials in a composite endpoint. The five concepts for inclusion were; seizures, expressive communication of the child, receptive communication of the child, impact on daily activities, and social functioning of the caregiver. CONCLUSIONS: This study showed the wider potential impact of DS to extend beyond that of seizures, demonstrating that there is a need for additional patient- and caregiver-relevant concepts to be measured in clinical trials to fully identify the value of therapeutic interventions.

BACKGROUND: In the phase 3 CheckMate 025 study, previously treated patients with advanced renal cell carcinoma who were randomly assigned to nivolumab had an overall survival benefit compared with those assigned to everolimus. We aimed to compare health-related quality of life (HRQoL) between treatment groups in this trial. METHODS: CheckMate 025 was an open-label study done at 146 oncology centres in 24 countries. Patients were randomly assigned to treatment between Oct 22, 2012, and March 11, 2014. Patients with advanced renal cell carcinoma were randomly assigned (1:1, block size of four) to receive nivolumab every 2 weeks or everolimus once per day. The study was stopped early at the planned interim analysis in July, 2015, because the study met its primary endpoint. A protocol amendment permitted patients in the everolimus group to cross over to nivolumab treatment. All patients not on active study therapy are being followed up for survival. At the interim analysis, HRQoL was assessed with the Functional Assessment of Cancer Therapy-Kidney Symptom Index-Disease Related Symptoms (FKSI-DRS) and European Quality of Life (EuroQol)-5 Dimensions (EQ-5D) questionnaires. Prespecified endpoints were to assess, in each treatment group, disease-related symptom progression rate based on the FKSI-DRS and changes in reported global health outcomes based on the EQ-5D. Other endpoints were post hoc. We calculated the proportion of FKSI-DRS questionnaires completed using the number of patients with non-missing data at baseline and at least one post-baseline visit. We defined FKSI-DRS completion as completion of five or more of the nine items in the questionnaire; otherwise data were treated as missing. FKSI-DRS symptom index score was prorated for missing items. We made no adjustments for missing EQ-5D data. We used descriptive statistics and multivariate analyses, including mixed-effects model repeated-measures, for between group comparisons. Analyses were powered according to the original study protocol, and we analysed FKSI-DRS and EQ-5D data for all patients who underwent randomisation and had a baseline assessment and at least one post-baseline assessment. CheckMate 025 is registered with ClinicalTrials.gov, number NCT01668784. FINDINGS: HRQoL data were collected at baseline for 362 (88%) of 410 patients in the nivolumab group and 344 (84%) of 411 patients in the everolimus group. The mean difference in FKSI-DRS scores between the nivolumab and everolimus groups was 1·6 (95% CI 1·4-1·9; p<0·0001) with descriptive statistics and 1·7 (1·2-2·1; p<0·0001) with mixed-effects model repeated-measures analysis. In terms of FKSI-DRS score, more patients had a clinically meaningful (ie, an increase of at least 2 points from baseline) HRQoL improvement with nivolumab (200 [55%] of 361 patients) versus everolimus (126 [37%] of 343 patients; p<0·0001). Median time to HRQoL improvement was shorter in patients given nivolumab (4·7 months, 95% CI 3·7-7·5) than in patients given everolimus (median not reached, NE-NE). INTERPRETATION: Nivolumab was associated with HRQoL improvement compared with everolimus in previously treated patients with advanced renal cell carcinoma. FUNDING: Bristol-Myers Squibb.

BACKGROUND: Maintenance monotherapy with the poly(ADP-ribose) polymerase inhibitor olaparib significantly prolongs progression-free survival over placebo in patients with platinum-sensitive relapsed serous ovarian cancer, with greatest benefit seen in patients with a BRCA1/2 mutation (BRCAm). Preservation of health-related quality of life (HRQoL) is important during maintenance therapy; we evaluated the effect of olaparib on HRQoL in this Phase II trial (NCT00753545, Study 19). METHODS: Patients received olaparib 400 mg b.i.d. (capsules) or placebo until progression. Patient-reported HRQoL and disease-related symptoms were evaluated using the FACT-Ovarian (FACT-O) questionnaire (completed at baseline and every 28 days until progression), the FACT/NCCN Ovarian Symptom Index (FOSI) and the Trial Outcome Index (TOI). TOI of the FACT-O was the primary measure. RESULTS: Overall, 265 women were randomised to maintenance olaparib (n=136) or placebo (n=129). Compliance for HRQoL assessment was high (â¼80% over time). Most patients in both arms reported a best response of 'no change' on TOI (81%) and other HRQoL measures. There were no statistically significant differences in time to worsening or improvement rates of TOI, FOSI and FACT-O scores in the overall, BRCAm and germline BRCAm populations. CONCLUSIONS: Maintenance treatment with olaparib was well tolerated and had no adverse impact on HRQoL in this study of patients with platinum-sensitive relapsed serous ovarian cancer who had responded to their most recent platinum-based therapy (partial or complete response). Interpretation of the HRQoL results in this population may differ from patients who have not responded to their most recent platinum-based therapy.

INTRODUCTION: Tuberculosis (TB) is a leading cause of morbidity and mortality in South Africa. Clinical parameters are important objective outcomes in TB; however they often are not directly correlated with subjective well-being of the patient, but can be assessed using patient-reported outcome (PRO) measures. Health-related quality of life (HRQOL) is a specific PRO generally multi-dimensional in nature and includes physical, mental and social health domains. The inclusion of HRQOL PROs in trials and clinical practice can provide additional information beyondclinical and microbiological parameters. Furthermore, HRQOL may be associated with medication adherence. This review focuses on patient-reported HRQOL and its association with medication adherence in TB patients in South Africa. METHODS: A comprehensive search strategy was developed focusing on the impact of TB on patient-reported HRQOL,the existence of a conceptual framework of TB-specific HRQOL, determinants of medication adherence and the association of HRQOL with medication adherence. Data were extracted from all identified articles and additionaldata extraction was performed by two independent reviewers with special focus on longitudinal studies in order to understand changes of HRQOL and adherence over time. Research gaps were identified with regard to patient-reported HRQOL and medication adherence. RESULTS: A total of 66 articles met the eligibility criteria. Ten HRQOL studies and one adherence study used a longitudinal design, none of these in South Africa. A variety of different generic and disease-specific HRQOL measures were identified in the articles. In South Africa four HRQOL and five adherence studies (non-longitudinal) were published. Similar factors (socio-demographic, socio-economic, disease-related, therapy-related and psycho-social aspects) affect HRQOL and adherence. Although standard TB treatment improved all health domains, psychological well-being and social functioning remained impaired in microbiologically cured patients after treatment. CONCLUSION: While evidence of TB impact on HRQOL and medication adherence and their association exists, it is verylimited for the South African situation. No valid and reliable TB-specific HRQOL measures were identified in this systematicreview. An assessment of HRQOL in TB patients in South Africa is required as this may assist with improving current disease management programmes, medication adherence and national treatment guidelines.

BACKGROUND: Malignant pleural mesothelioma (MPM) is a rare and usually fatal malignancy frequently linked to occupational asbestos exposures and associated with poor prognosis and considerable humanistic burden. The study aimed to develop conceptual models of the health-related quality of life (HRQoL) impact on patients with and receiving treatment for MPM, and the burden on their caregivers. METHODS: This multi-country study (Australia and United Kingdom) adopted a qualitative methodology to conduct semi-structured, independent interviews with people with MPM (n = 26), current caregivers (n = 20), and caregivers of people who had recently died because of MPM (n = 4). Participants were recruited using a purposive sampling approach and interviews conducted via telephone between January 2021 and January 2022. Transcripts were analysed using thematic analysis and used to construct conceptual models. RESULTS: Patient analysis yielded four overarching themes: (1) debilitating burden of breathlessness and fatigue; (2) physical mesothelioma symptoms experienced by patients; (3) distress of MPM on the self and family; and (4) treatment is worth 'having a go' despite the potential impact on symptoms. Caregiver analysis yielded five core themes: (1) daily life limited by caregiving duties; (2) emotional well-being and the need for support; (3) the relational role shift to caregiver; (4) time spent providing care negatively impacts work and productivity; and (5) positive aspects and outcomes of caregiving. CONCLUSIONS: This study highlights the substantial daily and emotional HRQoL impact that MPM symptoms have on patients and caregivers. Both groups reduced work, productivity, and social and leisure activities. There was evidence of positive HRQoL impacts as a result of immunotherapy and radiotherapy, but less for chemotherapy. Caregiver impacts were intensified during the end-of-life period and persisted following patient death. Evident is a need for increased psychological support, information, and advice for caregivers, increased during the end-of-life period.
RESUMEN
Introduction: A better understanding of patient experience of intravenous (IV) or subcutaneous (SC) routes of administration is fundamental to providing optimal administration of medical therapies to oncology patients. The objective of this study was to examine patient experiences of IV and SC treatment with nivolumab and confirm the relevance of item concepts in the Patient Experience and Preference Questionnaire (PEPQ). The PEPQ is a clinical outcomes' assessment instrument developed to obtain patient-centric data and understand the experience with IV and SC treatment administration. Methods: Embedded qualitative interviews were conducted with a subset of participants from three treatment cohorts with metastatic non-small-cell lung cancer (NSCLC), renal cell carcinoma (RCC), unresectable or advanced metastatic melanoma, hepatocellular carcinoma (HCC), or colorectal cancer (CRC) from the CA209-8KX clinical trial. Concept elicitation interviews were conducted within 14 days of the initial treatment cycle and patient experiences with IV and SC treatment administration were assessed. Concepts from interviews were mapped to the PEPQ version 1.0 questions to assess relevance and convergence of concepts. Results: Interviews were conducted with 43 trial participants from clinical sites opting to participate from six countries (Argentina, France, the Netherlands, Poland, Spain, and New Zealand). The mean age of sub-study participants was 66 ± 11.3 years (range 24-80 years), and 67.4% (N = 29) were male. Sub-study participants with experience of SC most frequently reported symptoms or signs of injection-related redness (27.9%), itching (14.0%), and pain (of needle), and described the pain as pricking, stinging, or tingling (11.0% each). The amount of pain and time burden were widely endorsed as important factors for satisfaction and related to the route of medication administration. For 11 sub-study participants with experience with both IV and SC treatments, 10 (90.9%) preferred SC over IV treatment administration. Conclusion: This study summarizes the experience and satisfaction of receiving IV or SC treatment and confirms the relevance of the PEPQ in a subgroup of CA209-8KX clinical trial participants with metastatic NSCLC, RCC, melanoma, HCC, and CRC. Participant treatment experience and satisfaction with the route of medication mapped to the PEPQ question content support the relevance of PEPQ v2.0 in clinical trials as a self-report measure.
