Project description:IntroductionMyasthenia gravis (MG) is a rare, debilitating, chronic disorder caused by the production of pathogenic immunoglobulin G autoantibodies against the neuromuscular junction. A lack of real-world studies in rare diseases reflects a relatively limited understanding of the significant unmet needs and burden of disease for patients. We aimed to provide comprehensive real-world insights into the management and burden of MG from treating physicians in the United States (US).MethodsData were collected using the Adelphi Real World MG Disease Specific Programme™, a point-in-time survey of physicians and their patients with MG, in the US between March and July 2020. Physician-reported clinical data, including demographics, comorbidities, symptoms, disease history, treatments, and healthcare resource utilization, were collected.ResultsIn total, 456 patient record forms were completed by 78 physicians based in the US. At time of survey completion, patient mean age was 54.5 years. Mean time from symptom onset to diagnosis was 9.0 months (n = 357). Ocular symptoms were reported in 71.7% of patients. General fatigue affected 47.1% of patients and over half of those reported the severity as moderate or severe (59.5%, n = 128). Acetylcholinesterase inhibitors and/or steroids were the most frequently prescribed first-line treatment type among patients receiving treatment at time of survey completion and with moderate-to-severe symptoms (77.9%, n = 159/204). High-dose steroids (n = 14) and intravenous immunoglobulin (n = 13) were the most prescribed acute treatments among those receiving an acute treatment at time of survey completion (n = 36), with symptom exacerbations or myasthenic crises being the most common reasons for acute treatment. On average, 2.5 healthcare professionals were involved in patient management and 5.0 consultations were made per patient over the last 12 months.ConclusionsOur findings indicated that, despite treatment, there is a proportion of patients with MG in the US who had a significant need for improved disease management.

Project description:BackgroundHealthcare stakeholders have pronounced both enthusiasm and apprehension over the expanding use of real-world evidence (RWE). The patient community-those who benefit from new treatments but are vulnerable to potential safety risks and whose routine medical encounters are used to generate RWE-has been less vocal. Understanding patient perspectives on the use of RWE to guide clinical decision making and inform regulatory decisions and value assessments is imperative.MethodsWe convened a day-long, multi-stakeholder roundtable in Washington D.C., USA, on 31 July 2017 to gather patient-community views on RWE and related concerns and the communications, information and tools needed by patients to understand, trust, and use RWE. Participants included a convenience sample of National Health Council (NHC) members primarily representing patient groups as well as non-patient members with an interest in RWE. Participants were organized into small, pre-assigned groups, ensuring representativeness across stakeholders and patient leadership. Discussions, including storyboards, notes, and illustrative examples were captured and later analyzed thematically by NHC staff.ResultsTen RWE themes emerged: (1) most patients were unaware of RWE and its actual or potential uses, (2) common definitions for real-world data and RWE are needed, (3) patient organizations need RWE skills and tools, (4) patient-scientist partnerships can help differentiate high-quality RWE, (5) RWE should inform decision making, (6) clinician support is needed for RWE uptake in patient decision making, (7) communications to patients should be balanced and empowering, (8) context of use impacts RWE acceptability/trust, (9) privacy/data ownership require clarity, and (10) patient-generated data are also real-world data (RWD).ConclusionPatients see great possibility in using RWE to understand how a treatment works-to find someone that "looks like me" as assurance of how a treatment might benefit them personally. Patient groups will play a critical role in helping to educate constituents on understanding, contributing to, and using RWE. To maximize patient uptake and the co-development and application of RWE, patient groups require education and tools.

Project description:BackgroundThere has been resurgence in the use of bismuth quadruple therapy (proton pump inhibitor, bismuth, tetracycline and metronidazole) for treating Helicobacter pylori infection thanks to a three-in-one single-capsule formulation.ObjectiveTo evaluate the effectiveness and safety of the single-capsule bismuth quadruple therapy.MethodsData were collected in a multicentre, prospective registry of the clinical practice of gastroenterologists on the management of H. pylori infection, where patients were registered at the Asociación Española de Gastroenterologia REDCap database on an electronic case report form until January 2020. Effectiveness by modified intention-to-treat and per-protocol as well as multivariable analysis were performed. Independent factors evaluated were: age, gender, indication, compliance, proton pump inhibitor dose and treatment line.ResultsFinally, 2100 patients were prescribed single-capsule bismuth quadruple therapy following the technical sheet (i.e., three capsules every 6 h for 10 days). The majority of these patients were naive (64%), with an average age of 50 years, 64% women and 16% with peptic ulcer. An overall modified intention-to-treat effectiveness of 92% was achieved. Eradication was over 90% in first-line treatment (95% modified intention-to-treat, n = 1166), and this was maintained as a rescue therapy, both in second (89% modified intention-to-treat, n = 375) and subsequent lines of therapy (third to sixth line: 92% modified intention-to-treat, n = 236). Compliance was the factor most closely associated with treatment effectiveness. Adverse events were generally mild to moderate, and 3% of patients reported a severe adverse event, leading to discontinuation of treatment in 1.7% of cases.ConclusionsSingle-capsule bismuth quadruple therapy achieved H. pylori eradication in approximately 90% of patients in real-world clinical practice, both as a first-line and rescue treatment, with good compliance and a favourable safety profile.

Project description:BackgroundMaintenance niraparib at an individualized starting dose (ISD) is established in platinum-sensitive recurrent ovarian cancer (PSROC). However, patients' perspectives on the burden of prolonged maintenance therapy have not been reported in prospective trials or routine practice.MethodsIn the real-life multicenter NiQoLe study, patients with PSROC received ISD maintenance niraparib. The primary objective was to describe physician-reported adverse events (AEs) leading to treatment modification during the first 3 months. Secondary endpoints included patient-reported outcomes (symptomatic AEs using PRO-CTCAE, self-reported fatigue, and impact on daily activities/function using FACT-F) collected remotely weekly using a specifically designed electronic device.ResultsMost (80%) of 139 treated patients (median age = 70 years) began niraparib at 200 mg/day. Median treatment duration was 5.7 (range = 0.2-21.4) months. During the first 3 months, 86 patients (62%) required treatment modification (median = 27 days to modification). Physician-reported grade ≥3 niraparib-related AEs occurred in 34 patients (24%); 68 patients (49%) had treatment modification for AEs, predominantly thrombocytopenia. The most frequent patient-reported AEs (PRO-CTCAE) were fatigue, insomnia, constipation, and dry mouth. Self-reported AEs were severe in 66% of patients. At baseline, 33% of patients reported severe fatigue (FACT-F), which generally persisted during niraparib. Physicians systematically underestimated major patient-reported symptoms.ConclusionsIn routine practice, niraparib dose modification was often required during the first 3 months despite individualized dosing. Physicians underestimated the burden of fatigue and symptomatic AEs. Digital self-reporting of AEs is feasible, provides patient-centered information complementing physician-reported AEs, and allows fuller appreciation of toxicity in real-world studies.Clinical trial informationNCT03752216.
