Patient Confidence and Information Preferences During the Treatment Decision-making Process: Results From a Large Multiple Myeloma Patient Survey Across 12 Countries in Europe and Israel.

BACKGROUND: The relapsing nature of multiple myeloma (MM) means that patients typically receive different and multiple lines of therapy, requiring many treatment decisions over the disease course. The aim of this study was to explore patient confidence and information preferences during the treatment decision-making process. PATIENTS AND METHODS: A multinational, cross-sectional survey enrolled patients with MM. It was co-developed and distributed by Myeloma Patients Europe across 12 countries in Europe and Israel from May 2019 to March 2020. Eligibility criteria included a self-reported diagnosis of MM and being able to recall the decision-making process at the start of their latest treatment line. RESULTS: A total of 1559 patients were included, with complete responses received from 1081 (69%) patients. The median age range was 54 to 64 years; there was an equal gender split and 57% had their latest treatment decision made within the past year. Overall, 54% of patients felt "very confident" in the latest treatment decision. Patients deemed the most important information to be safety/tolerability and treatment effectiveness, but the latter was among the least frequently received. Most patients reported that their primary physician treating MM was their main source for all types of information (range, 62%-94%), with 87% of patients reporting a "very good" or "good" relationship with them. CONCLUSION: Over half of patients felt very confident in their latest treatment decision; however, patients reported not routinely receiving important treatment effectiveness information. Addressing the discrepancies between information that patients receive and consider important may enhance confidence in decision-making.

Real-world use of carfilzomib combined with lenalidomide and dexamethasone in patients with multiple myeloma in Europe and Israel.

Clinical trials have demonstrated the efficacy and safety of carfilzomib in patients with relapsed/refractory multiple myeloma (RRMM); however, prospective real-world data are limited. This real-world, prospective, observational study evaluated carfilzomib use, effectiveness and safety in adults with RRMM. Data are presented for a subset of patients (n = 383) who received carfilzomib in combination with lenalidomide and dexamethasone (KRd). The overall response rate (ORR) was 83.6% among 360 evaluable patients. Treatment responses were better when KRd was administered at earlier therapy lines than at later lines of therapy (ORR: second line, 85.3%; third line or later, 81.0%). In patients with the anti-CD38 antibody-refractory disease, ORR was higher when KRd was administered earlier than at later therapy lines (second line/third line, 75.0%; fourth line or later, 60.0%). An ORR of 68.1% and 82.0% was achieved in the lenalidomide-refractory and not lenalidomide-refractory subgroups, respectively. KRd was consistently administered per the European label (twice weekly dose of 27 mg/m2) and the median time to discontinuation was 14.6 months. The safety profile of KRd was consistent with previous studies. These real-world data highlight the effectiveness of KRd as a treatment for patients with RRMM, including those with disease refractory to lenalidomide or anti-CD38 antibodies.

Real-world use of blinatumomab in adult patients with B-cell acute lymphoblastic leukemia in clinical practice: results from the NEUF study.

This retrospective observational study (NEUF) included adult patients with B-cell acute lymphoblastic leukemia (B-cell ALL) who had received blinatumomab for the treatment of minimal residual disease-positive (MRD+) or relapsed/refractory (R/R) B-cell ALL via an expanded access program (EAP). Patients were eligible if blinatumomab was initiated via the EAP between January 2014 and June 2017. Patients were followed from blinatumomab initiation until death, entry into a clinical trial, the end of follow-up, or the end of the study period (December 31, 2017), whichever occurred first. Of the 249 adult patients included, 109 were MRD+ (83 Philadelphia chromosome-negative [Ph-] and 26 Philadelphia chromosome-positive [Ph+]) and 140 had a diagnosis of R/R B-cell ALL (106 Ph- and 34 Ph+). In the MRD+ group, within the first cycle of blinatumomab treatment, 93% (n = 49/53) of Ph- and 64% (n = 7/11) of Ph+ patients with evaluable MRD achieved an MRD response (MRD <0.01%). Median overall survival (OS) was not reached over a median follow-up time of 18.5 months (Ph-, 18.8 [range: 5.1-34.8] months; Ph+, 16.5 [range: 1.8-31.6] months). In the R/R group, within two cycles of blinatumomab, 51% of Ph- and 41% of Ph+ patients achieved complete hematologic remission (CR/CRh/CRi), and 83% of Ph- and 67% of Ph+ MRD-evaluable patients in CR/CRh/CRi achieved an MRD response. Median (95% confidence interval) OS was 12.2 (7.3-24.2) months in the R/R Ph- subgroup and 16.3 (5.3-not estimated) months in the R/R Ph+ subgroup. This large, real-world data set of adults with B-cell ALL treated with blinatumomab confirms efficacy outcomes from published studies.

Real-World Use and Effectiveness of Carfilzomib Plus Dexamethasone in Relapsed/Refractory Multiple Myeloma in Europe.

This prospective, observational study examined the real-world use of carfilzomib across 11 European countries in adults with relapsed/refractory multiple myeloma (RRMM) who received at least one prior line of therapy. Carfilzomib and dexamethasone (Kd) use, effectiveness and safety were analyzed. In total, 271 patients received Kd among 701 adults enrolled. The median relative dose intensity of carfilzomib was 82.7% (20/56 mg/m2, twice weekly). The overall response rate (ORR) to Kd was 68.8% (95% confidence interval [CI], 62.7-74.5): 79.2% in second line (2L), 71.6% in third line (3L) and 63.1% in fourth line or later (4L+). The ORR was 59.9% (95% CI, 51.1-68.1) in the lenalidomide-refractory subgroup and 67.7% (95% CI, 48.6-83.3) in the not lenalidomide-refractory subgroup. In the anti-CD38 refractory subgroup, the ORR was 51.6% (95% CI, 38.6-64.5); ORRs were higher when Kd was received at 2L/3L (66.7%) than at 4L+ (49.1%). Overall, patients were treated for a median time of 7.7 months. One-fifth of patients reported treatment-related treatment-emergent adverse events (≥grade 3), with a safety profile consistent with previous clinical trials. This study demonstrated the real-world use, effectiveness and safety of Kd in patients with RRMM. Despite the increasing number of new therapeutic strategies to treat RRMM, Kd remains a safe and effective option, even for older, frail and lenalidomide- or anti-CD38 mAb-refractory patients.

Pediatric patients with acute lymphoblastic leukemia treated with blinatumomab in a real-world setting: Results from the NEUF study.

BACKGROUND: Prior to regulatory approval of blinatumomab in pediatric patients with relapsed/refractory Philadelphia chromosome-negative B-cell precursor acute lymphoblastic leukemia (R/R Ph- BCP-ALL), blinatumomab was made available via an expanded access program (EAP). PROCEDURE: This retrospective observational study included patients receiving blinatumomab in the EAP between January 1, 2014 and June 30, 2017 who were followed until death, entry into a clinical trial, end of follow-up, or end of the study period (December 31, 2017), whichever occurred first. RESULTS: Among 113 children enrolled, 72 were diagnosed with R/R Ph- BCP-ALL and 41 were minimal residual disease positive (MRD+, either Ph- or Ph+). In the R/R group, 38 (53%) patients achieved hematological response within two cycles. Of these, 19 (50%) proceeded to hematopoietic stem cell transplantation (HSCT) without bridging myelosuppressive therapy. Of 36 patients in the R/R group evaluable for MRD, 30 (83%) had an MRD response. In the R/R group, median relapse-free survival was 5.4 months and median overall survival (OS) was 8.2 months. Of 36 patients in the MRD+ group who were evaluable for MRD after two cycles, 27 (75%) had an MRD response. Overall, 24 (59%) of the MRD+ patients proceeded to HSCT without other bridging therapy. Median disease-free survival was 13.6 months; median OS was not reached. CONCLUSIONS: In this real-world pediatric cohort, blinatumomab was effective within two cycles. Over half of patients with R/R Ph- BCP-ALL achieved hematological response and most achieved MRD response in the MRD+ group, confirming the efficacy of blinatumomab in pediatric trials.

Evaluation of a prototype electronic personal health record for patients with idiopathic thrombocytopenic purpura.

BACKGROUND: Patients with rare diseases often lack information about the disease itself and appropriate health care, leading to poor quality of life. Personal health records provide health information which can then be shared between multiple health care providers. Personal health records may also offer a tool for capturing patients' reported outcomes, thus enhancing their empowerment and improving communication with health care professionals. We conducted a pilot study to evaluate the usability of Sanoia, a freely accessible personal health record, which was customized for patients with the rare disease, idiopathic thrombocytopenic purpura (ITP). METHODS: The Sanoia interface was expanded with ITP-specific tools. A prospective study was conducted at the referent center to evaluate the usability of this new interface (referred to here as the "tool") by patients. Forty-three patients were randomized into groups to use or to not use the tool. Its use was evaluated by a specific questionnaire and by surveying individual patient adherence profiles. Evaluation of health-related quality of life using the ITP patient assessment questionnaire, was performed at baseline and after 1, 3, and 6 months via postal mail. RESULTS: The groups were similar at inclusion in terms of characteristics, including global quality of life. During the study period, the tool was used to update the personal records of 19/28 patients (68%), with a median of two connections to the tool (range 1-12) plus access by various health care professionals (n = 22). In addition, 15/19 (78%) patients used the "personal notes" section at least once. We observed no significant changes in quality of life between patients with or without the tool during the study period. CONCLUSION: This pilot study demonstrates the good usability of the new customized Sanoia interface for patients with ITP. Additional studies will increase its usability further, and its interface could be adapted for use with other rare chronic diseases.
