Health-related quality of life in transplant-eligible patients with newly diagnosed multiple myeloma treated with daratumumab, lenalidomide, bortezomib, and dexamethasone: Patient-reported outcomes from GRIFFIN.

In the phase 2 GRIFFIN trial (ClinicalTrials.gov identifier: NCT02874742), daratumumab added to lenalidomide, bortezomib, and dexamethasone (D-RVd) improved depth of response and progression-free survival (PFS) versus lenalidomide, bortezomib, and dexamethasone (RVd) alone in transplant-eligible (TE) patients with newly diagnosed multiple myeloma (NDMM). Here, we present patient-reported outcomes (PROs) collected using the European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core 30-item (QLQ-C30), EORTC Quality of Life Questionnaire Multiple Myeloma Module 20-item (QLQ-MY20), and EuroQol 5-Dimension 5-Level (EQ-5D-5L) tools on day 1 of cycles 1, 2, and 3; on day 21 of cycle 4 (end of induction therapy); on day 1 of cycle 5; on day 21 of cycle 6 (end of posttransplant consolidation therapy); and at months 6, 12, 18, and 24 of maintenance therapy. Meaningful improvements from baseline were seen in most of the PRO scales with both treatments after consolidation and were sustained for at least 2 years of maintenance treatment. Large reductions from baseline (~20 points) were especially observed in pain symptoms for both treatment groups, although these were numerically higher for patients receiving D-RVd during the majority of the time points. In addition, improvements in key scales, such as global health status, fatigue symptoms, and physical functioning, were also seen with both D-RVd and RVd. These improvements in health-related quality of life contribute to the totality of evidence supporting the improvement in clinical outcomes such as response rates and PFS with D-RVd in induction, consolidation, and maintenance therapy in TE patients with NDMM.

Teclistamab Improves Patient-Reported Symptoms and Health-Related Quality of Life in Relapsed or Refractory Multiple Myeloma: Results From the Phase II MajesTEC-1 Study.

INTRODUCTION: Patients with relapsed or refractory multiple myeloma (RRMM) report significantly lower HRQoL compared with patients with newly diagnosed MM and experience further deterioration in HRQoL with each relapse and subsequent treatment. Therefore, consideration of the impact of treatment on HRQoL in addition to clinical outcomes is vital. PATIENTS AND METHODS: In the phase I/II MajesTEC-1 (NCT03145181, NCT04557098) study, patients with RRMM who received teclistamab, an off-the-shelf, T-cell redirecting BCMA × CD3 bispecific antibody, had deep and durable responses with manageable safety. HRQoL was assessed using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire core 30-item and the EuroQol 5 Dimension 5 Level descriptive questionnaire. Changes over time from baseline were measured with a repeated measures mixed-effects model. Proportions of patients with clinically meaningful improvement after starting treatment and time to clinically meaningful worsening were assessed. RESULTS: Compliance was maintained throughout the study. Compared with baseline, positive changes were observed for pain, global health status, and emotional functioning with treatment; other assessments were largely unchanged from baseline. Post hoc analysis showed patients with deeper clinical response generally reported improved HRQoL outcomes. Following an initial decline in HRQoL in some scales, the proportion of patients reporting clinically meaningful improvements increased, while the proportion reporting clinically meaningful worsening decreased over time. Clinically meaningful improvements in pain were reported in ≥40% of patients at most assessment time points. CONCLUSIONS: These results complement previously reported clinical benefits and support teclistamab as a promising therapeutic option for patients with RRMM.

Current Health State Affected Patient Preferences More Than Disease Status: A Discrete Choice Experiment in Multiple Myeloma.

OBJECTIVES: To examine how disease status and current health state influence treatment preferences of patients with multiple myeloma (MM). METHODS: Participants with MM from France, Germany, and the United Kingdom completed a web-based survey that included a discrete choice experiment (DCE) and EQ-5D assessment. The DCE elicited preferences for 8 attributes: increased life expectancy, increased time to relapse, pain, fatigue, risk of infection, administration (route and duration), frequency of administration, and monitoring. Multinomial logit models were used to analyze DCE preference data and to calculate life expectancy trade-offs. RESULTS: Three hundred participants with MM (newly diagnosed, transplant eligible, n = 108; newly diagnosed, transplant ineligible, n = 105; relapsed-refractory, n = 87) completed the survey. The most valued attributes were pain, fatigue, and increased life expectancy. Participants would want an additional 2.7 years of life expectancy (95% confidence interval [CI] 2.4-3.1 years) to tolerate extreme pain and an additional 2.0 years of life expectancy (95% CI 1.6-2.3 years) to tolerate constant fatigue. Participants in a better health state (third EQ-5D score quartile [0.897]) required less additional life expectancy than participants with a worse health state (first EQ-5D score quartile [0.662]) to tolerate extreme pain (2.3 years [95% CI 1.9-2.6 years] vs 3.0 years [95% CI 2.6-3.4 years]; P = .007). There was little difference in treatment preferences between newly diagnosed and relapsed-refractory patients for pain, fatigue, and increased life expectancy. CONCLUSIONS: Current health state influenced treatment preferences of patients with MM more than disease status and should be considered when making treatment decisions.

Patient Perceptions Regarding Ciltacabtagene Autoleucel Treatment: Qualitative Evidence From Interviews With Patients With Relapsed/Refractory Multiple Myeloma in the CARTITUDE-1 Study.

INTRODUCTION: Ciltacabtagene autoleucel (cilta-cel), a novel chimeric antigen receptor T (CAR-T) cell therapy, has demonstrated early, deep, and durable clinical responses in heavily pretreated patients with relapsed/refractory multiple myeloma (RRMM), and improvements in health-related quality of life (HRQoL) in CARTITUDE-1 (NCT03548207). Patient perspectives on treatment provide context to efficacy outcomes and are an important aspect of therapeutic evaluation. METHODS: Qualitative interviews were conducted in a subset of CARTITUDE-1 patients (n = 36) at screening, Day 100, and Day 184 post cilta-cel on living with MM, therapy expectations, and treatment experiences during the study. RESULTS: Patients most wanted to see change in symptoms with the greatest impact on HRQoL: pain (85.2%) and fatigue (74.1%). The primary treatment expectation was achieving remission (40.7%), followed by extended life expectancy (14.8%). Patients most often defined meaningful change as improvement in symptoms (70.4%) and return to normalcy (40.7%). The percentage of patients reporting symptoms (pain, fatigue, bone fracture, gastrointestinal, neuropathy, and weakness) decreased from 85.2% to 22.2% across symptom types at baseline to 29.2% to 0% on Day 184 after cilta-cel. Improved symptoms and positive sentiments corresponded with improved perception of overall health status and reduced pain level, respectively. Most patients reported that their expectations of cilta-cel treatment had been met (70.8%) or exceeded (20.8%) at Day 184, and 70.8% of patients considered cilta-cel therapy better than their previous treatments. CONCLUSION: Overall HRQoL improvements and qualitative interviews showed cilta-cel met patient expectations of treatment and suggest the long treatment-free period also contributed to positive sentiments.

Switching to daratumumab SC from IV is safe and preferred by patients with multiple myeloma.

INTRODUCTION: Two phase 3 studies demonstrated superior efficacy of intravenous daratumumab (DARA IV) plus bortezomib/melphalan/prednisone (ALCYONE) or lenalidomide/dexamethasone (Rd; MAIA) versus standard-of-care regimens for transplant-ineligible newly diagnosed multiple myeloma. In these studies, patients could switch from DARA IV to subcutaneous daratumumab (DARA SC) while receiving daratumumab monotherapy in ALCYONE (as of Cycle 11) or daratumumab plus Rd in MAIA. The phase 3 COLUMBA study demonstrated noninferiority of DARA SC to DARA IV. DARA SC reduced administration time, allowing patients to spend less time in healthcare settings, a relevant practical consideration for patient care in the COVID-19 pandemic/settings of limited healthcare resources. METHODS: DARA SC 1800 mg was administered every 4 weeks, per approved dosing schedules. We evaluated safety and patient-reported experience (ALCYONE only) among patients who switched from DARA IV to DARA SC. RESULTS: Fifty-seven patients in ALCYONE and 135 in MAIA switched to DARA SC. Three (2.2%; MAIA) patients reported injection-site reactions, all of which were mild. No infusion-related reactions occurred with DARA SC. In ALCYONE, >80% of patients preferred DARA SC over DARA IV. Grade 3/4 treatment-emergent adverse events (TEAEs) occurred in 5.3% of patients in ALCYONE and 25.9% in MAIA; one (0.7%; MAIA) patient experienced a TEAE with an outcome of death. CONCLUSION: For transplant-ineligible newly diagnosed multiple myeloma, DARA SC (monotherapy/with Rd) was safe and preferred over DARA IV. ClinicalTrials.gov, NCT02195479/NCT02252172.

Health-related quality of life in patients given ciltacabtagene autoleucel for relapsed or refractory multiple myeloma (CARTITUDE-1): a phase 1b-2, open-label study.

BACKGROUND: CARTITUDE-1 is a phase 1b-2 study evaluating ciltacabtagene autoleucel (cilta-cel), a chimeric antigen receptor T cell therapy with two B-cell maturation antigen-targeting single-domain antibodies, in patients with relapsed or refractory multiple myeloma. Primary efficacy outcomes have previously been reported. Here, we report health-related quality of life (HRQOL) secondary outcomes evaluated using patient-reported outcomes. METHODS: This single-arm, open-label, phwase 1b-2 study was done at 16 centres in the USA. Patients were aged 18 years or older with diagnosis of multiple myeloma and Eastern Cooperative Oncology Group performance status of 1 or less with three or more previous lines of therapy, or were double refractory to a proteasome inhibitor and immunomodulatory drug, and had received a proteasome inhibitor, immunomodulatory drug, and anti-CD38 antibody. A single cilta-cel infusion (target dose 0·75 × 106 CAR+ T cells per kg) was administered 5-7 days after lymphodepletion. Patient-reported outcomes were assessed using the European Organisation for Research and Treatment of Cancer (EORTC) quality of life questionnaire core 30-item, pre-specified items from the EORTC myeloma module, and EuroQol five-dimensional descriptive system questionnaire. Clinically meaningful changes in patient-reported outcomes were defined by anchor-based minimally important differences. This trial is registered with ClinicalTrials.gov, NCT03548207. This trial is completed but feeding into a long-term follow-up study. FINDINGS: Between July 16, 2018, and Oct 7, 2019, 78 patients were enrolled and underwent apheresis in phase 2 of the study. 68 patients were treated (43 [63%] male, 49 [72%] White), and their patient-reported outcomes assessed (median follow-up 16·9 months, IQR 15·7-17·5). After infusion, a transient decline was observed, followed by improvements in global health status (mean change from baseline to day 464 +8·0 points, SD 20·9), physical (+4·6 points, 21·1), and emotional functional scales (+1·9 points, 23·7) over time, and declines for symptom-based scores (-14·1 pain, SD 31·5 and -15·4 fatigue; SD 29·5), indicating improved patient HRQOL following treatment with cilta-cel. INTERPRETATION: These durable HRQOL improvements are consistent with clinical findings, in which a single cilta-cel infusion led to substantial and durable responses in heavily pre-treated patients with relapsed or refractory multiple myeloma. These results support the use of cilta-cel in patients with relapsed or refractory multiple myeloma. FUNDING: Janssen Research & Development and Legend Biotech USA.

Health-related quality of life in patients with light chain amyloidosis treated with bortezomib, cyclophosphamide, and dexamethasone ± daratumumab: Results from the ANDROMEDA study.

In the phase 3 ANDROMEDA trial, patients treated with daratumumab, bortezomib, cyclophosphamide, and dexamethasone (D-VCd) had significantly higher rates of organ and hematologic response compared with patients who received VCd alone. Here, we present patient-reported outcomes (PROs) from the ANDROMEDA trial. PROs were assessed through cycle 6 using three standardized questionnaires. Treatment effect through cycle 6 was measured by a repeated-measures, mixed-effects model. The magnitude of changes in PROs versus baseline was generally low, but between-group differences favored the D-VCd group. Results were generally consistent irrespective of hematologic, cardiac, or renal responses. More patients in the D-VCd group experienced meaningful improvements in PROs; median time to improvement was more rapid in the D-VCd group versus the VCd group. After cycle 6, patients in the D-VCd group received daratumumab monotherapy and their PRO assessments continued, with improvements in health-related quality of life (HRQoL) reported through cycle 19. PROs of subgroups with renal and cardiac involvement were consistent with those of the intent-to-treat population. These results demonstrate that the previously reported clinical benefits of D-VCd were achieved without decrement to patients' HRQoL and provide support of D-VCd in patients with AL amyloidosis.

The patient experience of relapsed refractory multiple myeloma and perspectives on emerging therapies.

BACKGROUND: Relapsed refractory multiple myeloma (RRMM) is a disease that is nonresponsive or progressive on therapy, and although patients can achieve remission, relapse is common. As more treatment options become available for multiple myeloma (MM), it is important to understand patients' experiences of current and emerging therapies. AIMS: This study aimed to better understand patient experiences with treatment and therapies for MM using qualitative interviews and patient-reported information (PRI) shared on social media. METHODS: Semistructured qualitative interviews were conducted with adults with RRMM who resided in the United States. In addition to the interviews, PRI was collected from YouTube and a patient advocacy website. Key themes from the interviews and PRI were summarized, and illustrative quotes were extracted. RESULTS: Twenty participants were interviewed; 11 were female, and mean (standard deviation) age was 60 (7.0) years. The PRI included 14 posts and 19 unique contributors (10 were female). Similar treatment-related symptoms were reported in the interviews and PRI. Fatigue and pain were the most frequently reported symptoms while receiving treatment in both the interviews and PRI. These symptoms had a meaningful impact on health-related quality of life (HRQOL); being off treatment and returning to normal living was described as an ideal treatment outcome. Nearly all interview participants (n = 18) preferred a treatment that would allow for a treatment-free interval, if it had the same efficacy and safety profile as a continuous treatment. CONCLUSION: The symptom experience reported in this study is consistent with known RRMM symptoms and HRQOL impacts. Additionally, this study highlighted that patients' treatment expectations are changing relative to their past treatment experience. Individuals living with RRMM strongly desire therapies with a treatment-free interval and minimal impact on their HRQOL.

Health-related quality of life in patients with relapsed/refractory multiple myeloma treated with pomalidomide and dexamethasone ± subcutaneous daratumumab: Patient-reported outcomes from the APOLLO trial.

In the phase 3 APOLLO trial, daratumumab in combination with pomalidomide and dexamethasone (D-Pd) significantly reduced the rate of disease progression or death by 37% relative to Pd alone in patients with relapsed/refractory multiple myeloma (RRMM) who had received ≥1 prior line of therapy including lenalidomide and a proteasome inhibitor. Here, we present patient-reported outcomes (PROs) from APOLLO. Median treatment duration was 11.5 months with D-Pd and 6.6 months with Pd. PRO compliance rates were high and similar in both groups. No changes from baseline were observed for EORTC QLQ-C30 global health status scores in either group, while physical and emotional functioning, disease symptoms, and adverse effects of treatment remained at baseline levels with D-Pd but worsened with Pd. Reductions (p < 0.05) in pain and fatigue were seen at several time points with D-Pd versus Pd. Overall, these results suggest patients' health-related quality of life remained stable when daratumumab was added to Pd, with several results favoring D-Pd versus Pd. These findings complement the significant clinical improvements observed with D-Pd and support its use in patients with RRMM.

Development of the Multiple Myeloma Symptom and Impact Questionnaire: A New Patient-Reported Outcome Instrument to Assess Symptom and Impacts in Patients With Multiple Myeloma.

OBJECTIVES: This study aimed to develop and assess the content validity of a patient-reported outcomes (PROs) instrument to measure symptoms and impacts experienced by patients with active multiple myeloma (MM). METHODS: The PRO instrument was developed using an iterative, mixed-methods approach. The list of concepts was generated based on a review of existing evidence (qualitative studies and literature) and post hoc psychometric evaluations of 2 PRO instruments in 3 clinical trials. A total of 30 adult patients with MM from the United States participated in hybrid concept elicitation/cognitive debriefing interviews to validate the content validity of the newly developed PRO instrument. Translatability assessment was completed in 8 languages. RESULTS: The item generation process resulted in 17 symptom and 9 impact concepts for evaluation. The concept elicitation interviews and analysis were based on the first 25 participants; evidence of saturation was observed. The cognitive debriefing interviews and analysis were based on the last 23 participants across 4 waves of interviews. On the basis patient feedback, 10 items were removed, and 1 item was added to the PRO instrument. The translatability assessment resulted in 1 minor revision. The multiple myeloma symptom and impact questionnaire (MySIm-Q) includes 11 symptom and 6 impact concepts, organized within 8 hypothesized subdomains, with each concept measured using a 5-point verbal rating scale and a 7-day recall period. CONCLUSIONS: The MySIm-Q instrument was developed using rigorous and mixed methodology and with direct input from patients who received a diagnosis of MM. The MySIm-Q has good content validity and is culturally relevant for use in global clinical trials.

Health-related quality of life in patients with newly diagnosed multiple myeloma ineligible for stem cell transplantation: results from the randomized phase III ALCYONE trial.

BACKGROUND: In the phase III ALCYONE trial, daratumumab plus bortezomib/melphalan/prednisone (D-VMP) significantly improved overall response rate and progression-free status compared with VMP alone in transplant-ineligible patients with newly diagnosed multiple myeloma (NDMM). Here, we present patient-reported outcomes (PROs) from ALCYONE. METHODS: The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30-item (EORTC QLQ-C30) and EuroQol 5-dimensional descriptive system (EQ-5D-5L) questionnaire were administered at baseline, every 3 months (year 1) and every 6 months (until progression). Treatment effects were assessed using a repeated-measures, mixed-effects model. RESULTS: Compliance with PRO assessments was comparable at baseline (> 90%) and throughout study (> 76%) for both treatment groups. Improvements from baseline were observed in both groups for EORTC QLQ-C30 Global Health Status (GHS), most functional scales, symptom scales and EQ-5D-5L visual analog scale (VAS). Between-group differences were significant for GHS (p = 0.0240) and VAS (p = 0.0160) at month 3. Improvements in pain were clinically meaningful in both groups at all assessment time points. Cognitive function declined in both groups, but the magnitude of the decline was not clinically meaningful. CONCLUSIONS: Patients with transplant-ineligible NDMM demonstrated early and continuous improvements in health-related quality of life, including improvements in functioning and symptoms, following treatment with D-VMP or VMP. TRIAL REGISTRATION: ClinicalTrials.gov identifier NCT02195479 , registered September 21, 2014.

Health-related quality of life in patients with relapsed or refractory multiple myeloma: treatment with daratumumab, lenalidomide, and dexamethasone in the phase 3 POLLUX trial.

In the phase 3 POLLUX trial, daratumumab in combination with lenalidomide and dexamethasone (D-Rd) significantly improved progression-free survival in patients with relapsed/refractory multiple myeloma (RRMM) compared with lenalidomide and dexamethasone (Rd) alone. Here, we present patient-reported outcomes (PROs) from POLLUX, assessed using the validated European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30-item (EORTC QLQ-C30) and the EuroQol 5-dimensional descriptive system (EQ-5D-5L) questionnaires. Changes from baseline are presented as least-squares mean changes with 95% confidence intervals (CIs) derived from a mixed-effects model. PRO assessment compliance rates were high and similar in both D-Rd and Rd groups through cycle 40 (week 156). In this on-treatment analysis, mean changes from baseline were significantly greater in EORTC QLQ-C30 global health status, physical functioning, and pain scores in the D-Rd group versus the Rd group at multiple time points; however, magnitude of changes was low, suggesting no meaningful impact on health-related quality of life (HRQoL). Subgroup results were similar to those in the overall population. In the POLLUX study, baseline HRQoL was maintained with prolonged D-Rd treatment. These findings complement the sustained and significant improvement in progression-free survival observed with D-Rd and supports its use in patients with RRMM. Clinical trial registration: NCT02076009.

Patient Perceptions Regarding Multiple Myeloma and Its Treatment: Qualitative Evidence from Interviews with Patients in the United Kingdom, France, and Germany.

BACKGROUND: The current standard of care for multiple myeloma requires several regimens of treatment, with patients experiencing high symptom burden and side effects, which negatively impact health-related quality of life (HRQoL). Thus, it is crucial to understand patient perceptions of multiple myeloma and how patients value different treatment options. OBJECTIVE: The purpose of this study was to conduct an exploratory investigation into concepts that could form attributes that influence treatment choices for patients with multiple myeloma and to identify trade-offs that patients are willing to make between treatment attributes. METHODS: In total, 30 patients with newly diagnosed or relapsed/refractory multiple myeloma from the UK, France, and Germany participated in semistructured interviews talking about their disease experience and symptoms, treatment benefits, treatment burden, perceived side effects, and benefit/risk trade-offs in treatment. The interview audio recordings were transcribed and analyzed using content analysis to identify treatment and disease aspects relevant to patients. RESULTS: Symptoms of fatigue and bone pain and treatment side effects of peripheral neuropathy, diarrhea, and constipation were cited by patients as the most disruptive to their HRQoL. Treatment duration was reported most frequently as a major treatment burden, and patients emphasized the importance of increased life expectancy as a treatment benefit. All patients showed good understanding of benefit/risk trade-offs in treatment, and some patients expressed a preference for more convenient modes of treatment administration. CONCLUSIONS: Qualitative interviews identified key aspects of multiple myeloma treatment that are most important to patients. These findings will inform a wider patient-preferences study, which could improve treatment choice and HRQoL for patients with multiple myeloma.

Health-related quality of life maintained over time in patients with relapsed or refractory multiple myeloma treated with daratumumab in combination with bortezomib and dexamethasone: results from the phase III CASTOR trial.

In the phase III CASTOR trial, daratumumab, bortezomib and dexamethasone (D-Vd) significantly extended progression-free survival compared with bortezomib and dexamethasone (Vd) alone in patients with relapsed/refractory multiple myeloma (RRMM). Here, we present patient-reported outcomes (PROs) from the CASTOR trial. PROs were assessed using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30-item (EORTC QLQ-C30) and the EuroQol 5-dimensional descriptive system questionnaire. Treatment effects through Cycle 8 were measured by a repeated measures mixed-effects model. After Cycle 8, PROs were only collected for patients in the D-Vd group who continued on daratumumab monotherapy. Compliance rates for PRO assessments were high and similar between treatment groups. Mean changes from baseline were generally similar between treatment groups for EORTC QLQ-C30 global health status (GHS), functioning and symptoms, and did not exceed 10 points for either treatment group. Subgroup analyses were consistent with the results observed in the overall population. There was no change in patients' health-related quality of life for the first eight cycles of therapy; thereafter, patients treated with daratumumab over the long-term reported improvements in GHS and pain. These results complement the significant clinical benefits observed with D-Vd in patients with RRMM and support its use in this patient population.

Subcutaneous daratumumab in Asian patients with heavily pretreated multiple myeloma: subgroup analyses of the noninferiority, phase 3 COLUMBA study.

The phase 3 COLUMBA study demonstrated noninferiority of subcutaneous daratumumab (DARA SC) to intravenous daratumumab (DARA IV) in relapsed or refractory multiple myeloma. We present a subgroup analysis of Asian patients from COLUMBA. Eligible patients had ≥ 3 prior lines of therapy, including a proteasome inhibitor and an immunomodulatory drug, or were double refractory. Co-primary endpoints were overall response rate (ORR) and maximum trough concentration (Ctrough). Secondary endpoints included rates of infusion-related reactions, progression-free survival, and patient-reported satisfaction with therapy. Sixty-seven Asian patients (DARA SC, n = 30; DARA IV, n = 37) were randomized, including 42 Japanese patients (DARA SC, n = 18; DARA IV, n = 24). Comparable ORRs for DARA SC versus DARA IV were seen in the Asian cohort (66.7% vs 43.2%) and Japanese-only cohort (61.1% vs 54.2%), including patients weighing ≤ 65 kg. Similarity of Ctrough was seen in both Asian and Japanese-only cohorts; the ratio of the geometric mean of the Ctrough concentrations for DARA SC/DARA IV was 143.96% (90% confidence interval (CI), 112.03-185.00%) and 148.02% (90% CI, 113.32-193.34%), respectively. The Asian cohort (both treatment groups) and Japanese-only cohort (DARA SC group) experienced higher rates of grade 3/4 cytopenias compared with the global COLUMBA population, occurring predominantly in patients of low bodyweight; no patients discontinued treatment due to cytopenias. The Cancer Therapy Satisfaction Questionnaire results generally favored DARA SC. In the Asian and Japanese-only cohorts, DARA SC was comparable to DARA IV. The efficacy, pharmacokinetic, safety, and satisfaction results were generally consistent with the global COLUMBA population regardless of patient bodyweight. ClinicalTrials.gov Identifier: NCT03277105.

Greater treatment satisfaction in patients receiving daratumumab subcutaneous vs. intravenous for relapsed or refractory multiple myeloma: COLUMBA clinical trial results.

PURPOSE: The phase III COLUMBA study evaluated daratumumab (DARA) intravenous (IV) and subcutaneous (SC) in patients with relapsed or refractory multiple myeloma. Here, we report patient-reported satisfaction with therapy (SWT) in COLUMBA. METHODS: DARA IV or DARA SC was administered weekly (cycles 1-2), every 2 weeks (cycles 3-6), and every 4 weeks (cycles 7 +). Patients completed a modified version of the Cancer Therapy Satisfaction Questionnaire (CTSQ) at weekly (cycles 1-2) and monthly (cycles 3 +) intervals and at the end of treatment. Results for each item and the SWT domain score were summarized using descriptive statistics. The distribution of responses for individual items was calculated for each assessment. The proportion of patients for whom SWT domain score change from first assessment met or exceeded the minimally important difference (MID) of 5.9 points was calculated at each assessment time point. RESULTS: Two-hundred fifty-nine patients were randomized to DARA IV and 263 to DARA SC. Mean scores for SWT domain questions were high and largely positive during treatment. Responses indicating positive perceptions of therapy were given by a numerically greater proportion of patients in the DARA SC group than the DARA IV group for most questions. Changes from the first assessment in SWT domain scores met or exceeded the MID for an average of ~ 40% of patients. CONCLUSION: In COLUMBA, modified CTSQ results suggest patients in the DARA SC group were more satisfied with their cancer therapy than those in the DARA IV group. TRIAL REGISTRATION: ClinicalTrials.gov identifier NCT03277105. Registered September 8, 2107.

Health-Related Quality of Life in Transplant-Ineligible Patients With Newly Diagnosed Multiple Myeloma: Findings From the Phase III MAIA Trial.

PURPOSE: To evaluate the effects of daratumumab, lenalidomide, and dexamethasone (D-Rd) versus lenalidomide and dexamethasone (Rd) on patient-reported outcomes (PROs) in the phase III MAIA study. PATIENTS AND METHODS: PROs were assessed on the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30-item and the EuroQol 5-dimensional descriptive system at baseline and every 3 months during treatment. By mixed-effects model, changes from baseline are presented as least squares means with 95% CIs. RESULTS: A total of 737 transplant-ineligible (TIE) patients with newly diagnosed multiple myeloma were randomly assigned to D-Rd (n = 368) or Rd (n = 369). Compliance with PRO assessments was high at baseline (> 90%) through month 12 (> 78%) for both groups. European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30-item global health status scores improved from baseline in both groups and were consistently greater with D-Rd at all time points. A global health status benefit was achieved with D-Rd, regardless of age (< 75 and ≥ 75 years), baseline Eastern Cooperative Oncology Group (ECOG) performance status score, or depth of response. D-Rd treatment resulted in significantly greater reduction in pain scores as early as cycle 3 (P = .0007 v Rd); the magnitude of change was sustained through cycle 12. Reductions in pain with D-Rd were clinically meaningful in patients regardless of age, ECOG status, or depth of response. Similarly, PRO improvements were observed with D-Rd and Rd on the EuroQol 5-dimensional descriptive system visual analog scale score. CONCLUSION: D-Rd compared with Rd was associated with faster and sustained clinically meaningful improvements in PROs, including pain, in transplant-ineligible patients with newly diagnosed multiple myeloma regardless of age, baseline ECOG status, or depth of treatment response.

Bortezomib, thalidomide, and dexamethasone with or without daratumumab for transplantation-eligible patients with newly diagnosed multiple myeloma (CASSIOPEIA): health-related quality of life outcomes of a randomised, open-label, phase 3 trial.

BACKGROUND: In part 1 of the two-part CASSIOPEIA study, treatment before and after autologous haematopoietic stem-cell transplantation (HSCT) with daratumumab plus bortezomib, thalidomide, and dexamethasone (D-VTd) significantly improved rates of stringent complete response and progression-free survival versus bortezomib, thalidomide, and dexamethasone (VTd) in patients with newly diagnosed multiple myeloma. METHODS: CASSIOPEIA is an ongoing randomised, open-label, active-controlled, parallel-group, phase 3 trial done at 111 academic and community practice centres in Europe. Transplantation-eligible adults with newly diagnosed multiple myeloma were randomly assigned (1:1) to D-VTd or VTd. Treatment consisted of four 28-day cycles of induction therapy before autologous HSCT and two 28-day cycles of consolidation therapy after. In this prespecified secondary analysis, patient-reported outcomes were assessed using the European Organization for Research and Treatment of Cancer quality of life questionnaire-core 30-item (EORTC QLQ-C30) and EuroQol 5-dimensional descriptive system (EQ-5D-5L) questionnaire at baseline, after induction (cycle 4, day 28), and after consolidation (day 100 after autologous HSCT). The analysis was done in all patients in the intention-to-treat population with a baseline and at least one post-baseline patient-reported outcome assessment. The trial is registered at ClinicalTrials.gov (NCT02541383). FINDINGS: Between Sept 22, 2015, and Aug 1, 2017, 1085 patients were enrolled and randomly assigned D-VTd (n=543) or VTd (n=542). Questionnaire completion rates were high at baseline (511 [94%] of 543 in the D-VTd group vs 510 [94%] of 542 in the VTd group). Compliance rates (calculated from the number of completed surveys as a proportion of the predicted number of participants still on study treatment) were high at post-induction (431 [84%] of 513 vs 405 [80%] of 509) and post-consolidation (414 [90%] of 460 vs 386 [88%] of 438) assessments and were similar between treatment groups. Mean changes in global health status scores from baseline to post-induction were not different between the D-VTd group (3·8 [95% CI 1·6 to 6·0]) and VTd group (2·9 [0·7 to 5·1]; p=0·43), or from baseline to post-consolidation between the two groups (D-VTd group, 9·7 (95% CI 7·4 to 11·9) vs VTd group, 8·7 (6·5 to 11·0; p=0·45). Improvements from baseline in EORTC QLQ-C30 global health status and EQ-5D-5L visual analogue scale scores were observed in post-consolidation scores in both groups. Post-consolidation scores showed significantly greater mean decreases in pain (-23·3 [95% CI -26·6 to -20·0] in the D-VTd group vs -19·7 [-23·0 to -16·3] in the VTd group; p=0·042), significantly smaller reductions in cognitive functioning (-5·0 [-7·6 to -2·4] vs -7·9 [-10·6 to -5·3]; p=0·036), and significantly greater improvements in emotional functioning (13·0 [10·4 to 15·5] vs 9·5 [6·9 to 12·1]; p=0·013) and in constipation (-3·2 [-7·3 to 0·9] vs 1·8 [-2·4 to 6·0]; p=0·025) with D-VTd versus VTd. Between-group differences in change from baseline for all other scales were not significant. INTERPRETATION: D-VTd and VTd were associated with on-treatment health-related quality of life improvements from baseline in transplantation-eligible patients with newly diagnosed multiple myeloma. The significantly greater reductions in pain, less deterioration of cognitive functioning, and greater emotional functioning improvements complement the clinical benefits observed with D-VTd versus VTd, and support the addition of daratumumab to standard regimens in patients with newly diagnosed multiple myeloma.

Symptom burden and health-related quality of life impacts of smoldering multiple myeloma: the patient perspective.

BACKGROUND: Smoldering multiple myeloma (SMM) is an early form of multiple myeloma (MM). SMM is typically considered asymptomatic, and research on how it affects health-related quality of life (HRQoL) is limited. This study assessed the symptoms and HRQoL of patients with SMM and those who progressed from SMM to MM and evaluated the content validity of two patient-reported outcome instruments (EORTC QLQ-C30 and nine items from the EORTC QLQ-MY20) for use in SMM clinical trials. To address these objectives, concept elicitation and cognitive interviews were conducted with SMM patients and recently diagnosed MM patients. RESULTS: Fifteen adult SMM and six adult MM participants with a prior SMM diagnosis were interviewed. On average, SMM study participants were 61 years old (46.0-78.0), 11 (73%) were female, and diagnosed 2.6 (±2.0) years ago. Each participant had experienced at least one symptom, most commonly tiredness/fatigue, weakness, and pain. The most common HRQoL impacts were emotional and physical. SMM study participants demonstrated good understanding of both the EORTC QLQ-C30 and EORTC QLQ-MY20 subscales and found them relevant to their SMM health state. The average age of MM participants was 53 years old (39.0-62.0); 5 (83%) were female and diagnosed 1.9 years ago (±2.1). MM participants most commonly reported tiredness, weakness, constipation, shortness of breath, and dry mouth as occurring when they progressed from SMM to MM. CONCLUSIONS: Although previously described as asymptomatic, these SMM participants reported experiencing symptoms that affected their lives. Additionally, the EORTC subscales measured symptoms SMM patients experienced. The participants with MM reported that the symptom burden and HRQoL impacts increased when diagnosed with MM. These findings suggest the need for increased surveillance of symptoms within the SMM population and further suggest that the EORTC subscales can be used to assess symptoms and impacts in both the SMM and MM populations.

Using a digital patient powered research network to identify outcomes of importance to patients with multiple myeloma.

BACKGROUND: Social media platforms give patients a voice by allowing them to discuss their health and connect with others. These unfiltered and genuine reports offer direct access to what matters most to patients. Exploring the patient-reported outcomes discussed in these platforms reveal clinical insights and behavioral patterns of the real-world patient journey. This research study reviewed health-related quality of life (HRQoL) concepts reported by patients with multiple myeloma (MM). METHODS: Data were obtained using the Belong.life patient-powered research network (PPRN) using social media listening methods. The analysis cohort consisted of adults diagnosed with MM who signed into the Belong.life platform by June 2018. Natural language processing and medical neural networks were utilized to extract text data to mine and scan for concepts using programmed algorithms. The textual review of the data was conducted on two levels: the over-arching concept of interest (broad symptom and impact classification) and the more specific symptom and impacts report. Concepts were analyzed descriptively and summarized by age, gender, context of report, and stage of disease/treatment journey. RESULTS: Two hundred thirty patients with MM from the United States (52%), Israel (42%), Canada (3%), and 3% from Egypt, France, Greece, India, United Kingdom, and Australia were identified. A total of 57% were female and at account registration the median age was 57 years. A total of 126 patients had evaluable text data to search concepts being discussed. The PPRN platform identified 93% of the concepts from the conceptual model developed based on prior literature review. The most commonly reported symptoms were neuropathy, tiredness, nausea, back pain, fatigue, and bone pain. Back pain appeared as the most prominent symptom early in the disease and sometimes occurred prior to MM diagnosis. Tiredness, nausea, fatigue, and bone pain were frequently reported after MM diagnosis, with the start of treatment. CONCLUSION: Patient-oriented social media platforms, such as Belong.life, can capture and contribute to a holistic vision of concepts surrounding patients' HRQoL. The ability to understand when a certain debilitating symptom appeared and to which sub-population of patients may allow for a personalized approach to treatment, improving adherence and quality of care as well as increasing patient well-being.
