The Influence of Patient-Reported Joint Manifestations on Quality of Life in Fabry Patients.

ABSTRACT: Fabry disease, a lysosomal storage disorder, is a rare inborn error of metabolism caused by deficiency of the enzyme alpha galactosidase A and resulting accumulation of globotriaosylceramide. The symptoms of Fabry disease are heterogeneous including renal failure, cardiac hypertrophy, and stroke and may not be well recognized by non-specialist physicians. Patients with milder, later onset of disease often have a delay in diagnosis.Fabry patients may suffer significant neuropathic pain in the extremities (acroparasthesia) but the degree to which musculoskeletal symptoms contribute to total pain and disability is unknown. Here, we present a questionnaire study focusing on joint manifestations and their impact on daily life of patients with Fabry disease.Seventy-seven patients with Fabry disease and age-matched healthy controls (49 female and 28 male) took part in a survey focused on joint problems, pain, disability, and quality of life. Joint pain and swelling were reported by 43% of male and 39% of female Fabry patients. Analysis by age group showed higher prevalence of joint problems and decreased quality of life, in terms of mobility, activity, pain, and anxiety, in Fabry patients younger than 50 years compared to healthy controls. Female Fabry patients had higher fatigue scores compared to control subjects. Fabry patients reported problems with vigorous daily activities and gripping.Musculoskeletal symptoms are common in Fabry patients and contribute to overall pain and decreased quality of life. Awareness of Fabry disease by physicians may be raised to ensure timely diagnosis of this rare disease.

Project description:INTRODUCTION:Fabry disease is an X-linked lysosomal storage disorder caused by a deficiency of ?-galactosidase A. Symptoms include neuropathic pain and gastrointestinal problems, such as diarrhoea. To inform and support the design of a Phase III clinical trial for a new oral treatment for Fabry disease, this study evaluated patients' experiences of Fabry disease symptoms, the impact of symptoms on their quality of life, and their views on participating in clinical trials. METHODS:An online survey questionnaire was distributed to patients with Fabry disease, through relevant patient organisations. The questionnaire consisted mainly of quantitative, closed questions with pre-defined response options. Fabry-specific pain intensity and its impact on quality of life were rated on a scale from 0 to 10. RESULTS:In total, 367 patients completed the survey, of whom half reported frequent pain, moderate to severe pain, and pain in their hands and feet. Pain frequency, intensity and location were similar for males and females. There was no clear association between Fabry-specific pain and the use of enzyme replacement therapy (ERT), with moderate to severe pain reported by 80.4% of participants receiving ERT and by 75.0% of participants not receiving ERT. Of participants who were receiving ERT, 35.7% said they were willing to discontinue it to take part in a clinical trial testing a new oral drug for treating Fabry disease. Gastrointestinal symptoms were more heterogeneous in nature and frequency than Fabry-specific pain, but still affected a significant proportion of participants. CONCLUSIONS:Both male and female patients with Fabry disease experience significant Fabry-specific pain, which affects their quality of life. Furthermore, frequent diarrhoea affects many patients. The symptoms occur independently of the use of ERT. This suggests the healthcare needs of patients with Fabry disease are not being fully met, and additional treatments are required to improve symptoms and quality of life.

Project description:IntroductionDirectly recorded patient experience of symptoms and health-related quality of life (HRQoL) can complement lung function and exacerbation rate data in chronic obstructive pulmonary disease (COPD) clinical studies. The FULFIL study recorded daily symptoms and activity limitation together with additional patient-reported outcomes of dyspnea and HRQoL, as part of the prespecified analyses. FULFIL co-primary endpoint data have been previously reported.MethodsFULFIL was a phase III, 24-week, randomized, double-blind, double-dummy, multicenter study comparing once-daily single inhaler triple therapy [fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI)] 100 µg/62.5 µg/25 µg with twice-daily inhaled corticosteroid/long-acting β2-agonist therapy [budesonide/formoterol (BUD/FOR)] 400 µg/12 µg in patients with symptomatic COPD at risk of exacerbations. A subset participated for 52 weeks. Patient-reported assessments were: Evaluating Respiratory Symptoms in COPD™ (E-RS: COPD), St George's Respiratory Questionnaire (SGRQ) for COPD, COPD Assessment Test (CAT), baseline and transitional dyspnea indices (TDI) and daily and global anchor questions for activity limitation.ResultsFF/UMEC/VI showed greater reductions from baseline in 4-weekly mean E-RS: COPD total and all subscale scores compared with BUD/FOR; differences were statistically significant (P < 0.05) at each time period. FF/UMEC/VI also demonstrated greater improvements from baseline at weeks 4 and 24 in SGRQ domain scores and TDI focal score compared with BUD/FOR. At weeks 4 and 24, improvements greater than the minimal clinically important difference from baseline were observed in CAT score with FF/UMEC/VI, but not BUD/FOR; differences were statistically significant (P ≤ 0.003).ConclusionThese findings demonstrate sustained daily symptom and HRQoL benefits of FF/UMEC/VI versus BUD/FOR. The inclusion of the CAT may provide data that are readily generalizable to everyday clinical practice.Trial registrationClinicalTrials.gov number: NCT02345161.FundingGSK.

Project description:BackgroundQuality of life (QOL) can be significantly impacted by symptoms of overactive bladder (OAB). Vibegron is a highly selective β3 -adrenergic receptor agonist that showed efficacy in treatment of symptoms of OAB in the randomised, double-blind, placebo- and active-controlled phase 3 EMPOWUR trial. Here we report patient-reported QOL outcomes from the EMPOWUR trial.MethodsPatients were randomly assigned 5:5:4 to receive vibegron 75 mg, placebo or tolterodine 4 mg extended release, respectively, for 12 weeks. Patients completed the OAB questionnaire (OAB-q) at baseline and at week 12 and the patient global impression (PGI) scales for severity, control, frequency and leakage at baseline and at weeks 4, 8 and 12. Change from baseline at week 12 and responder rates (OAB-q: patients achieving a ≥10-point improvement; PGI: patients reporting best possible response) were assessed. Vibegron was compared with placebo, and no comparisons were made between vibegron and tolterodine.ResultsOf the 1518 patients randomised, 1463 (placebo, n = 520; vibegron, n = 526; tolterodine, n = 417) had evaluable data for efficacy measures and were included in the analysis. Mean baseline OAB-q and PGI scores were comparable among treatment groups. At week 12, patients receiving vibegron had greater improvements from baseline in OAB-q subscores of coping, concern, sleep, health-related QOL total and symptom bother (P < .01 each) compared with patients receiving placebo; a greater proportion of patients receiving vibegron vs placebo were responders in the OAB-q coping (P < .05) and symptom bother scores (P < .0001). Compared with placebo, a greater proportion of patients who received vibegron achieved the best response on all PGI end-points at week 12 (P < .05 each) and were classified as responders (P < .05 each).ConclusionsIn the 12-week EMPOWUR trial, treatment with vibegron was associated with significantly greater and clinically meaningful improvement in OAB-q and PGI scores compared with placebo, consistent with improvements in OAB symptoms.Clinical trial registrationClinicalTrials.gov identifier number NCT03492281.

Project description:IntroductionTocilizumab (TCZ) monotherapy has been proven as an effective treatment for rheumatoid arthritis (RA) in clinical trials. However, there are limited data available regarding the effectiveness of TCZ monotherapy in real-world clinical settings in the United States. The objective of this study was to evaluate the impact of TCZ monotherapy on disease activity and patient-reported outcomes (PROs) in a US-based observational cohort of patients with RA seen in routine clinical practice.MethodsEligible patients had active RA, no prior use of TCZ, and initiated TCZ as monotherapy. Changes in disease activity and PROs were assessed 1 year after TCZ initiation for the overall cohort and stratified by number of prior tumor necrosis factor inhibitors (TNFis; 0, 1, or ≥2). Primary outcomes were change in Clinical Disease Activity Index (CDAI); change in patient global disease activity, pain, fatigue; and the proportions of patients with improvement in modified Health Assessment Questionnaire (mHAQ), morning stiffness, and EQ-5D.ResultsOf 255 eligible TCZ monotherapy initiators, 9.4% were TNFi naive, 36.5% had one prior TNFi, and 54.1% had ≥2 prior TNFis. Clinical and PRO measures indicated that patients were substantially impacted by their disease at baseline. The median decrease in CDAI from baseline to 1 year was 9.8 and median patient global and pain scores improved by 10 mm, indicative of clinically meaningful improvement; the median fatigue score improved by 5 mm. Approximately 26% of patients reported clinically meaningful improvement in mHAQ, 54% experienced improvement in morning stiffness, and 20% to 36% experienced improvement in EQ-5D domains (walking, self-care, usual activities, pain/discomfort, and anxiety/depression). Improvements were similar across TNFi groups.ConclusionsPatients with active, refractory RA who initiated TCZ monotherapy experienced improvements in both composite disease activity scores and PROs at 1 year, regardless of prior TNFi exposure.FundingCorrona, LLC and Genentech.
