- Background: Clinical trials of disease-modifying therapies in PD require valid and responsive primary outcome measures that are relevant to patients. Objectives: The objective is to select a patient-centered primary outcome measure for disease-modification trials over three or more years. Methods: Experts in Parkinson's disease (PD), statistics, and health economics and patient and public involvement and engagement (PPIE) representatives reviewed and discussed potential outcome measures. A larger PPIE group provided input on their key considerations for such an endpoint. Feasibility, clinimetric properties, and relevance to patients were assessed and synthesized. Results: Although initial considerations favored the Movement Disorder Society-sponsored revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part III in Off, feasibility, PPIE input, and clinimetric properties supported the MDS-UPDRS Part II. However, PPIE input also highlighted the importance of nonmotor symptoms, especially in the longer term, leading to the selection of the MDS-UPDRS Parts I + II sum score. Conclusions: The MDS-UPDRS Parts I + II sum score was chosen as the primary outcome for large 3-year disease-modification trials. © 2023 The Authors.

- Background: Multi-arm, multi-stage (MAMS) platform trials can accelerate the identification of disease-modifying treatments for Parkinson's disease (PD) but there is no current consensus on the optimal outcome measures (OM) for this approach. Objective: To provide an up-to-date inventory of OM for disease-modifying PD trials, and a framework for future selection of OM for such trials. Methods: As part of the Edmond J Safra Accelerating Clinical Trials in Parkinson Disease (EJS ACT-PD) initiative, an expert group with Patient and Public Involvement and Engagement (PPIE) representatives' input reviewed and evaluated available evidence on OM for potential use in trials to delay progression of PD. Each OM was ranked based on aspects such as validity, sensitivity to change, participant burden and practicality for a multi-site trial. Review of evidence and expert opinion led to the present inventory. Results: An extensive inventory ofOMwas created, divided into: general, motor and non-motor scales, diaries and fluctuation questionnaires, cognitive, disability and health-related quality of life, capability, quantitative motor, wearable and digital, combined, resource use, imaging and wet biomarkers, and milestone-based. A framework for evaluation of OM is presented to update the inventory in the future. PPIE input highlighted the need for OM which reflect their experience of disease progression and are applicable to diverse populations and disease stages. Conclusion: We present a range of OM, classified according to a transparent framework, to aid selection of OM for disease-modifying PD trials, whilst allowing for inclusion or re-classification of relevant OM as new evidence emerges.

- ObjectiveVertebrobasilar artery nonsaccular aneurysms (VBANSAs) are associated with a 13% annual mortality. Revascularization and flow diversion are life-saving options in select cases; technical failures and rapid hemodynamic changes may contribute to unwanted outcomes. We describe a technique and report clinical outcomes of patients treated with an experimental slow-closing clip (SCC).MethodsAn experimental SCC was created to gradually close the parent artery of aneurysms. Clinical, radiographic, and outcome data from patients with VBANSAs who underwent experimental treatment with the SCC were retrospectively analyzed.ResultsAmong 10 patients (7 men; mean age, 49.5 years; range, 18–73 years), 6 presented with mass effect symptoms, 1 with ischemic stroke, 2 with subarachnoid hemorrhage, and 1 with hydrocephalus. Five patients underwent revascularization plus SCC application, and 5 were treated with SCC alone. The mean follow-up was 6.7 years. The expected mortality among patients with unruptured VBANSAs with previous treatment options in this period was 52.7%, whereas the observed rate was 20%. Four patients died within 12 months after treatment. Causes of death were brainstem ischemic stroke, poor-grade subarachnoid hemorrhage, poor clinical presentation, and unknown. Six patients were alive at last follow-up, with unchanged or improved modified Rankin Scale scores. Mortality was associated with posterior-projecting aneurysms and late-stage treatment.ConclusionsIn this small case series, use of SCC overcame the natural history of VBANSAs when treatment timing and aneurysm anatomy were suitable. The SCC potentially favors aneurysm thrombosis and collateral reactivation. More studies are necessary to better develop the SCC.

- BACKGROUND: Cardiovascular disease (CVD) influences phenotypic variation in Parkinson's disease (PD), and is usually an indication for statin therapy. It is less clear whether cardiovascular risk factors influence PD phenotype, and if statins are prescribed appropriately.OBJECTIVES: To quantify vascular risk and statin use in recent-onset PD, and examine the relationship between vascular risk, PD severity and phenotype.METHODS: Cardiovascular risk was quantified using the QRISK2 calculator (high ≥20%, medium ≥10 and <20%, low risk <10%). Motor severity and phenotype were assessed using the Movement Disorder Society Unified PD Rating Scale (UPDRS) and cognition by the Montreal cognitive assessment.RESULTS: In 2909 individuals with recent-onset PD, the mean age was 67.5 years (SD 9.3), 63.5% were men and the mean disease duration was 1.3 years (SD 0.9). 33.8% of cases had high vascular risk, 28.7% medium risk, and 22.3% low risk, while 15.2% of cases had established CVD. Increasing vascular risk and CVD were associated with older age (p<0.001), worse motor score (p<0.001), more cognitive impairment (p<0.001) and worse motor phenotype (p=0.021). Statins were prescribed in 37.2% with high vascular risk, 15.1% with medium vascular risk and 6.5% with low vascular risk, which compared with statin usage in 75.3% of those with CVD.CONCLUSIONS: Over 60% of recent-onset PD patients have high or medium cardiovascular risk (meriting statin usage), which is associated with a worse motor and cognitive phenotype. Statins are underused in these patients, compared with those with vascular disease, which is a missed opportunity for preventive treatment.TRIAL REGISTRATION NUMBER: GN11NE062, NCT02881099.
