Eur J Haematol 2024; 112:900-909. [PMID: 38350661 DOI: 10.1111/ejh.14183] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2023] [Revised: 01/19/2024] [Accepted: 01/22/2024] [Indexed: 02/15/2024]
Abstract
OBJECTIVE To evaluate the psychometric properties of the AL-PROfile, a patient-reported outcome measure combining the Patient-Reported Outcomes Measurement Information System (PROMIS)-29, two items from PROMIS Cognitive Function, and select Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE) items. METHODS Content validity was assessed through cognitive debriefing interviews of 20 patients who completed the AL-PROfile (Study 1). Study 2 involved 297 participants who completed the AL-PROfile and Medical Outcomes Study 36-item Short-Form Health Survey (SF-36). Reliability (internal consistency and test-retest reliability) and validity (convergent and discriminant validity, known groups validity by stage/organ involvement) were calculated. RESULTS Study 1 participants found the AL-PROfile straightforward confirming the relevance of the included content. Some felt that certain questions were not related to their amyloidosis experience. Study 2 demonstrated acceptable internal consistency for all domains/items except PROMIS Cognitive Function and acceptable test-retest reliability for all except PROMIS Cognitive Function and PRO-CTCAE nausea. Large correlations were seen for the same domain across measures while correlations for divergent domains within a measure and different domains across different measures were small. The PRO-CTCAE items showed small to medium correlations with each other and with PROMIS and SF-36 domains. Stage was associated with physical function, fatigue, social roles, swelling, and shortness of breath scores. CONCLUSION The AL-PROfile has acceptable reliability and validity for use in systemic light chain amyloidosis patients.

Health-Related Quality of Life Instruments for Clinical Trials in AL Amyloidosis: Report from the Amyloidosis Forum HRQOL Working Group. Patient Relat Outcome Meas 2023; 14:153-169. [PMID: 37229285 PMCID: PMC10202704 DOI: 10.2147/prom.s399658] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2022] [Accepted: 03/23/2023] [Indexed: 05/27/2023] Open
Abstract
Systemic AL (light chain) amyloidosis is a rare protein misfolding disorder associated with plasma cell dyscrasia affecting various organs leading to organ dysfunction and failure. The Amyloidosis Forum is a public-private partnership between the Amyloidosis Research Consortium and the US Food and Drug Administration Center for Drug Evaluation and Research with the goal of accelerating the development of effective treatments for AL amyloidosis. In recognition of this goal, 6 individual working groups were formed to identify and/or provide recommendations related to various aspects of patient-relevant clinical trial endpoints. This review summarizes the methods, findings, and recommendations of the Health-Related Quality of Life (HRQOL) Working Group. The HRQOL Working Group sought to identify existing patient-reported outcome (PRO) assessments of HRQOL for use in clinical trials and practice deemed relevant across a broad spectrum of patients with AL amyloidosis. A systematic review of the AL amyloidosis literature identified 1) additional signs/symptoms not currently part of an existing conceptual model, and 2) relevant PRO instruments used to measure HRQOL. The Working Group mapped content from each identified instrument to areas of impact in the conceptual model to determine which instrument(s) provide coverage of relevant concepts. The SF-36v2® Health Survey (SF-36v2; QualityMetric Incorporated, LLC) and Patient-Reported Outcomes Measurement Information System-29 Profile (PROMIS-29; HealthMeasures) were identified as instruments relevant to patients with AL amyloidosis. Existing evidence of reliability and validity was evaluated with a recommendation for future work focused on estimating clinically meaningful within-patient change thresholds for these instruments. For sponsors, the context of use-including specific research objectives, trial population, and investigational product under study-should inherently drive selection of the appropriate PRO instrument and endpoint definitions to detect meaningful change and enable patient-focused drug development.

A cross-sectional study of patient-reported outcomes and symptom burden using PROMIS and PRO-CTCAE measures in light chain amyloidosis. Qual Life Res 2023; 32:1807-1817. [PMID: 36738402 DOI: 10.1007/s11136-023-03354-9] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 01/21/2023] [Indexed: 02/05/2023]
Abstract
BACKGROUND We conducted a cross-sectional study to characterize health-related quality of life and symptom burden in individuals living with light chain (AL) amyloidosis. METHODS Members of the Amyloidosis Support Groups, Inc. with AL amyloidosis who consented to this IRB-approved survey provided information on their amyloidosis diagnosis, treatment, symptoms, and functioning. HRQL was measured using PROMIS and PRO-CTCAE questionnaires. RESULTS Among 297 participants who responded, the median age at diagnosis was 60 years (23-82) with 52% female and 90% white race. There were 69% AL (lambda) and 39% reported 3 or more organs involved with amyloidosis (58% cardiac, 58% renal, 30% neurological AL). Time from diagnosis was less than 2 years in 64 (22%), 2-5 years in 105 (36%), > 5 years in 126 (43%), and unknown in 2 (< 1%) individuals. Therapy included prior chemotherapy in 88% and stem cell transplant in 52%. Fifty percent of the cohort was on active treatment. Multiple domains were impaired in AL amyloidosis compared to the general population, including physical function, fatigue, and social roles. While highest among those within 2 years of diagnosis, high symptom burden was also seen in long-term survivors. A trend to decreased severity and number of impaired symptoms was seen with longer treatment-free interval but many symptoms remained persistent. CONCLUSIONS Significant and persistent symptom burden is seen in AL amyloidosis. Patient-reported outcomes should be routinely measured and used to provide best supportive care to all AL amyloidosis patients, including long-term survivors and those not on active therapy.

Abstract
Patient-reported outcome measures (PROMs), which are measures of symptom burden, health-related quality of life (HRQoL), and therapy effectiveness have become increasingly important in clinical research. They are unique in that they are reported directly from the patient, without clinician interpretation, thereby avoiding clinician bias. With an increased focus on the patient at the center of health care, PROMs have been increasingly incorporated into clinical research, systematic reviews, and clinical guidelines. Despite the recognition of the importance of including PROMs into clinical haematologic cancer research, barriers have prevented their integration into cancer research. This review highlights the value of including PROMs into clinical haematologic cancer research and addresses the methodological challenges in using and evaluating PROMs. We propose important questions for the malignant haematologist to consider when designing or evaluating a study that includes PROMs.

Abstract
Immunoglobulin light chain (AL) amyloidosis is a disorder of clonal plasma cells characterized by deposition of amyloid fibrils in a variety of tissues, leading to end-organ injury. Renal or cardiac involvement is most common, though any organ outside the central nervous system can develop amyloid deposition, and symptomatic presentations may consequently vary. The variability and subtlety of initial clinical presentations may contribute to delayed diagnoses, and organ involvement is often quite advanced and symptomatic by the time a diagnosis is established. Additionally, while organ function can improve with plasma-cell-directed therapy, such improvement lags behind hematologic response. Consequently, highly effective supportive care, including symptom management, is essential to improve quality of life and to maximize both tolerance of therapy and likelihood of survival. Considering the systemic nature of the disease, close collaboration between clinicians is essential for effective management.

Abstract
Immunoglobulin light chain amyloidosis is a rare, multisystemic, phenotypically heterogenous disease affecting cardiovascular, renal, neurological, and gastrointestinal systems to varying degrees. Its underlying cause is a plasma cell dyscrasia characterized by misfolding of monoclonal immunoglobulin light chains which leads to aggregation and deposition of insoluble amyloid fibrils in target organs. Prognosis is primarily dependent on extent of cardiac involvement and depth of hematologic response to treatment. To facilitate development of new therapies, a public-private partnership was formed between the nonprofit Amyloidosis Research Consortium and the US Food and Drug Administration Center for Drug Evaluation and Research. In 2020, the Amyloidosis Forum launched an initiative to identify novel/composite end points and analytic strategies to expedite clinical trials for development of new therapies for the primary hematologic disorder and organ system manifestations. Specialized working groups identified organ-specific end points; additional working groups reviewed health-related quality of life measures and statistical approaches to data analysis. Each working group comprised amyloidosis experts, patient representatives, statisticians, and representatives from the Food and Drug Administration, the UK Medicines and Healthcare Products Regulatory Agency, and pharmaceutical companies. This review summarizes the proceedings and recommendations of the Cardiac Working Group. Using a modified Delphi method, the group identified, reviewed, and prioritized cardiac end points relevant to immunoglobulin light chain amyloidosis in the context of an antiplasma cell therapy. Prioritized cardiovascular end points included overall survival, hospitalization, N-terminal pro-B-type natriuretic peptide level, 6-minute walk test, Kansas City Cardiac Questionnaire, and cardiac deterioration progression-free survival. These recommended components will be further explored through evaluation of clinical trial datasets and formal guidance from regulatory authorities.
