Background Eculizumab has transformed management of paroxysmal nocturnal hemoglobinuria (PNH) since its approval. However, its biweekly dosing regimen remains a high treatment burden. Ravulizumab administered every 8 weeks demonstrated noninferiority to eculizumab in two phase 3 trials. In regions where two PNH treatment options are available, it is important to consider patient preference. Objective The aim of this study was to assess patient preference for ravulizumab or eculizumab. Methods Study 302s (ALXN1210-PNH-302s) enrolled PNH patients who participated in the extension period of phase 3 study ALXN1210-PNH-302. In the parent study, eculizumab-experienced adult PNH patients received ravulizumab or eculizumab during a 26-week primary evaluation period. All patients in the extension period received ravulizumab. In study 302s, patient treatment preference was evaluated using an 11-item PNH-specific Patient Preference Questionnaire (PNH-PPQ©). Of 98 patients, 95 completed PNH-PPQ© per protocol for analysis. Results Overall, 93% of patients preferred ravulizumab whereas 7% of patients either had no preference (6%) or preferred eculizumab (1%) (P < 0.001). For specific aspects of treatment, ravulizumab was preferred (in comparison to no preference or eculizumab) on infusion frequency (98% vs. 0% vs. 2%), ability to plan activities (98% vs. 0% vs. 2%), and overall quality of life (88% vs. 11% vs. 1%), among other aspects. Most participants selected frequency of infusions as the most important factor determining preference (43%), followed by overall quality of life (23%). Conclusion This study shows that a substantial proportion of patients preferred ravulizumab over eculizumab and provides an important patient perspective on PNH treatment when there is more than one treatment option.

Sleep as a predictor of tDCS and language therapy outcomes
2022
Abstract
Study Objectives
To determine whether sleep at baseline (before therapy) predicted improvements in language following either language therapy alone or coupled with transcranial direct current stimulation (tDCS) in individuals with primary progressive aphasia (PPA).
Methods
Twenty-three participants with PPA (mean age 68.13 ± 6.21) received written naming/spelling therapy coupled with either anodal tDCS over the left inferior frontal gyrus (IFG) or sham condition in a crossover, sham-controlled, double-blind design (ClinicalTrials.gov identifier: NCT02606422). The outcome measure was percent of letters spelled correctly for trained and untrained words retrieved in a naming/spelling task. Given its particular importance as a sleep parameter in older adults, we calculated sleep efficiency (total sleep time/time in bed x100) based on subjective responses on the Pittsburgh Sleep Quality Index (PSQI). We grouped individuals based on a median split: high versus low sleep efficiency.
Results
Participants with high sleep efficiency benefited more from written naming/spelling therapy than participants with low sleep efficiency in learning therapy materials (trained words). There was no effect of sleep efficiency in generalization of therapy materials to untrained words. Among participants with high sleep efficiency, those who received tDCS benefitted more from therapy than those who received sham condition. There was no additional benefit from tDCS in participants with low sleep efficiency.
Conclusion
Sleep efficiency modified the effects of language therapy and tDCS on language in participants with PPA. These results suggest sleep is a determinant of neuromodulation effects.

apraxia of speech (AOS)
2021
Transcranial direct current stimulation (tDCS) over the left inferior frontal gyrus (IFG) was found to improve oral and written naming in post-stroke and primary progressive aphasia (PPA), speech fluency in stuttering, a developmental speech-motor disorder, and apraxia of speech (AOS) symptoms in post-stroke aphasia. This paper addressed the question of whether tDCS over the left IFG coupled with speech therapy may improve sound duration in patients with apraxia of speech (AOS) symptoms in non-fluent PPA (nfvPPA/AOS) more than sham. Eight patients with non-fluent PPA/AOS received either active or sham tDCS, along with speech therapy for 15 sessions. Speech therapy involved repeating words of increasing syllable-length. Evaluations took place before, immediately after, and two months post-intervention. Words were segmented into vowels and consonants and the duration of each vowel and consonant was measured. Segmental duration was significantly shorter after tDCS compared to sham and tDCS gains generalized to untrained words. The effects of tDCS sustained over two months post-treatment in trained and untrained sounds. Taken together, these results demonstrate that tDCS over the left IFG may facilitate speech production by reducing segmental duration. The results provide preliminary evidence that tDCS may maximize efficacy of speech therapy in patients with nfvPPA/AOS.

Protocol for a type 2 hybrid effectiveness-implementation study expanding, implementing and evaluating electronic health record-integrated patient-reported symptom monitoring in a multisite cancer centre
2022
IntroductionCancer symptom monitoring and management interventions can address concerns that may otherwise go undertreated. However, such programmes and their evaluations remain largely limited to trials versus healthcare systemwide applications. We previously developed and piloted an electronic patient-reported symptom and need assessment (‘cPRO’ for cancer patient-reported outcomes) within the electronic health record (EHR). This study will expand cPRO implementation to medical oncology clinics across a large healthcare system. We will conduct a formal evaluation via a stepped wedge trial with a type 2 hybrid effectiveness-implementation design.Methods and analysisAim 1 comprises a mixed method evaluation of cPRO implementation. Adult outpatients will complete cPRO assessments (pain, fatigue, physical function, depression, anxiety and supportive care needs) before medical oncology visits. Results are available in the EHR; severe symptoms and endorsed needs trigger clinician notifications. We will track implementation strategies using the Longitudinal Implementation Strategy Tracking System. Aim 2 will evaluate cPRO’s impact on patient and system outcomes over 12 months via (a) a quality improvement study (n=4000 cases) and (b) a human subjects substudy (n=1000 patients). Aim 2a will evaluate EHR-documented healthcare usage and patient satisfaction. In aim 2b, participating patients will complete patient-reported healthcare utilisation and quality, symptoms and health-related quality of life measures at baseline, 6 and 12 months. We will analyse data using generalised linear mixed models and estimate individual trajectories of patient-reported symptom scores at baseline, 6 and 12 months. Using growth mixture modelling, we will characterise the overall trajectories of each symptom. Aim 3 will identify cPRO implementation facilitators and barriers via mixed methods research gathering feedback from stakeholders. Patients (n=50) will participate in focus groups or interviews. Clinicians and administrators (n=40) will complete surveys to evaluate implementation. We will graphically depict longitudinal implementation survey results and code qualitative data using directed content analysis.Ethics and disseminationThis study was approved by the Northwestern University Institutional Review Board (STU00207807). Findings will be disseminated via local and conference presentations and peer-reviewed journals.Trial registration number NCT04014751; ClinicalTrials.gov.

Content validation of the National Comprehensive Cancer Network/Functional Assessment of Cancer Therapy Lymphoma Symptom Index-18 (NFLymSI-18) in indolent B-cell non-Hodgkin’s lymphoma
2024
Background
The NFLymSI-18 is a patient-reported outcome measure comprised of the highest priority symptoms, emotional concerns, treatment side effects, and other concerns identified by lymphoma patients and oncologists. This study assessed the content validity of the NFLymSI-18 for patients with indolent B-cell non-Hodgkin’s lymphoma (iNHL), with a focus on the Disease-Related Symptoms Physical (DRS-P) subscale.
Methods
Patients with a confirmed iNHL diagnosis who had received one or more lines of treatment were recruited during clinic visits. Patients described their symptoms, treatment side effects, and emotional concerns related to iNHL in a semi-structured interview. Qualitative data were analyzed using NVivo10.
Results
Data saturation was obtained by the 18th interview. Most participants (67%) had follicular lymphoma. 28% of participants had marginal zone lymphoma, and one participant had lymphoplasmacytoid lymphoma/Waldenström macroglobulinemia. Mean age of the 18 participants was 67 years. 56% of the sample was male. Most participants (67%) had a college or advanced degree. When asked to describe their iNHL symptoms, patients most often discussed swelling (
n
= 14), fatigue (
n
= 11), and pain (
n
= 8). The following symptoms were mentioned by three patients each: anxiety, appetite loss, rash, sleep disruption, trouble breathing, and malaise. Mapping of NFLymSI-18 content to these concerns showed the instrument includes all those most frequently mentioned symptoms.
Conclusions
This study supports the content validity of the NFLymSI-18, including its DRS-P Subscale, for patients with iNHL. The instrument shows strong validity for the most referenced symptoms of swelling, fatigue, and pain. The diversity of additional symptoms reported by patients is consistent with the heterogeneous symptomology of iNHL.

Neural Correlates of Letter and Semantic Fluency in Primary Progressive Aphasia
2021
Verbal fluency (VF) is an informative cognitive task. Lesion and functional imaging studies implicate distinct cerebral areas that support letter versus semantic fluency and the understanding of neural and cognitive mechanisms underlying task performance. Most lesion studies include chronic stroke patients. People with primary progressive aphasia (PPA) provide complementary evidence for lesion-deficit associations, as different brain areas are affected in stroke versus PPA. In the present study we sought to determine imaging, clinical and demographic correlates of VF in PPA. Thirty-five patients with PPA underwent an assessment with letter and category VF tasks, evaluation of clinical features and an MRI scan for volumetric analysis. We used stepwise regression models to determine which brain areas are associated with VF performance while acknowledging the independent contribution of clinical and demographic factors. Letter fluency was predominantly associated with language severity (R2 = 38%), and correlated with the volume of the left superior temporal regions (R2 = 12%) and the right dorsolateral prefrontal area (R2 = 5%). Semantic fluency was predominantly associated with dementia severity (R2 = 47%) and correlated with the volume of the left inferior temporal gyrus (R2 = 7%). No other variables were significantly associated with performance in the two VF tasks. We concluded that, independently of disease severity, letter fluency is significantly associated with the volume of frontal and temporal areas whereas semantic fluency is associated mainly with the volume of temporal areas. Furthermore, our findings indicated that clinical severity plays a critical role in explaining VF performance in PPA, compared to the other clinical and demographic factors.

A mixed methods evaluation of patient perspectives on the implementation of an electronic health record-integrated patient-reported symptom and needs monitoring program in cancer care
2024
Background
As cancer centers have increased focus on patient-centered, evidenced-based care, implementing efficient programs that facilitate effective patient-clinician communication remains critical. We implemented an electronic health record-integrated patient-reported symptom and needs monitoring program (‘cPRO’ for

utcomes). To aid evaluation of cPRO implementation, we asked patients receiving care in one of three geographical regions of an academic healthcare system about their experiences.
Methods
Using a sequential mixed-methods approach, we collected feedback in two waves.
Wave 1
included virtual focus groups and interviews with patients who had completed cPRO. In
Wave 2
, we administered a structured survey to systematically examine
Wave 1
themes. All participants had a diagnosed malignancy and received at least 2 invitations to complete cPRO. We used rapid and traditional qualitative methods to analyze
Wave 1
data and focused on identifying facilitators and barriers to cPRO implementation.
Wave 2
data were analyzed descriptively.
Results
Participants (
n
= 180) were on average 62.9 years old; were majority female, White, non-Hispanic, and married; and represented various cancer types and phases of treatment.
Wave 1
participants (
n
= 37) identified facilitators, including cPRO’s perceived value and favorable usability, and barriers, including confusion about cPRO’s purpose and various considerations for responding. High levels of clinician engagement with, and patient education on, cPRO were described as facilitators while low levels were described as barriers.
Wave 2
(
n
= 143) data demonstrated high endorsement rates of cPRO’s usability on domains such as navigability (91.6%), comprehensibility (98.7%), and relevance (82.4%).
Wave 2
data also indicated low rates of understanding cPRO’s purpose (56.7%), education from care teams about cPRO (22.5%), and discussing results of cPRO with care teams (16.3%).
Conclusions
While patients reported high value and ease of use when completing cPRO, they also reported areas of confusion, emphasizing the importance of patient education on the purpose and use of cPRO and clinician engagement to sustain participation. These results guided successful implementation changes and will inform future improvements.

Background
This study evaluated pre-defined aspects of content validity of the 18-item NCCN FACT-Ovarian Symptom Index (NFOSI-18) and its Disease-Related Symptoms-Physical (DRS-P) subscale, as clinical trial outcome tools for patients with advanced ovarian cancer.
Methods
Twenty-one women (mean age 59.5 years) diagnosed with advanced ovarian cancer completed the NFOSI-18 and participated in a cognitive interview to explore: (1) whether ‘pain’ and ‘cramps’ are considered redundant; (2) whether ‘fatigue’ and ‘lack of energy’ are overlapping concepts; (3) whether patients consider severity when responding to the item “I am bothered by constipation;” and (4) factors considered when responding to the item “I am sleeping well.” Interviews were audio-recorded, transcribed, and analyzed qualitatively.
Results
Pain was associated with discomfort, hurt, and life interference; ‘cramps’ was associated with pain, muscle tightening, and menstrual or digestive issues. Most (81%) considered the items “I have pain” and “I have cramps in my stomach area” to be more different than similar. Participants associated ‘fatigue’ with intense tiredness and ‘lack of energy’ with motivation and capability to complete daily activities. Item comparisons revealed a majority (65%) considered the items to be more different than similar. When responding to “I am bothered by constipation,” patients indicated constipation severity was related to bother. Finally, patients considered disease, treatment, and other factors when responding to “I am sleeping well.”
Conclusions
Findings support content validity of the NFOSI-18 and its DRS-P as originally constructed. We propose an alternative scoring option that excludes the item “I am sleeping well” from the DRS-P when used as a symptom-focused index for clinical research in a regulatory context.

Web-Based Cancer Symptom Self-Management System
2025
Patients with cancer and cancer survivors frequently experience symptoms that increase the need for health care services and impair quality of life. Effective symptom management is critical for comprehensive patient-centered cancer care.
To evaluate the effectiveness of adding a bilingual (English and Spanish), web-based self-management program to an electronic health record (EHR)-integrated patient-reported outcome for cancer (cPRO) assessment in reducing symptom burden and health care resource use (HCRU).
This patient-level randomized clinical trial was performed at the Northwestern Memorial HealthCare system in Chicago, Illinois. Participants included 1614 adult patients with cancer or cancer survivors in 30 clinics who were enrolled between April 1, 2020, and April 8, 2023, and followed up for 12 months until May 8, 2024.
Usual care (UC) consisting of an EHR-integrated cPRO assessment or enhanced care (EC), which offered an additional tailored web-based self-management program.
Patient-Reported Outcomes Measurement Information System measures of anxiety, depression, fatigue, pain interference, and physical function collected at baseline and monthly for 12 months. Secondary outcomes included HCRU measures (inpatient and/or observation visits and days, emergency department and/or urgent care visits, and days of hospital stay).
A total of 1614 patients were included in the analysis, with 804 randomized to EC and 810 to UC. The mean (SD) age was 61 (13) years; 1095 patients (67.8%) were female. Only 419 EC participants (52.1%) accessed the website, with only 197 (47%) returning; the median time per visit was 45 seconds (IQR, 45-105 seconds). There were no statistically significant differences between EC and UC across the cPRO outcomes over 12 months. The mean change from baseline at each assessment time point for treatment effects (EC vs UC) ranged from -0.19 (95% CI, -0.86 to 0.33; P = .64) for physical function to 0.11 (95% CI, -0.75 to 0.79; P = .87) for fatigue. Zero-inflated negative binomial and logistic regression models showed no significant differences in HCRU outcomes: inpatient and/or observation visits (incidence rate ratio [IRR], 0.90; 95% CI, 0.72-1.12), emergency department and/or urgent care visits (IRR, 0.99; 95% CI, 0.84-1.16), and days of hospital stay (IRR, 1.05; 95% CI, 0.83-1.33).
In this randomized clinical trial, adding a bilingual web-based self-management program to EHR-integrated cPRO did not reduce symptom burden or HCRU compared with cPRO alone. Low engagement with the web-based program highlights the need for strategies to enhance engagement and tailor interventions to those who would benefit most.
