 A Cognitive Occupation-Based programme for people with Multiple Sclerosis: definitive trial (COB-MS)
From
01 May 2025
To
30 April 2029
Summary
Cognitive difficulties can have significant impacts on daily function and quality of life of people with multiple sclerosis (MS). Although a common symptom of MS, it is often not treated in clinical care, despite the potential for devastating impacts. When treated, occupational therapists are the healthcare professionals most commonly responsible for the assessment and management of cognitive symptoms in MS. Despite this, no cognitive rehabilitation intervention has been developed that is measured by and taught through an occupational participation perspective. The Cognitive Occupation-Based programme for people with MS (COB-MS) was developed to address the clinical treatment deficit. The COB-MS is a personalised, patient-centred, holistic, occupational therapy, cognitive rehabilitation intervention. It is aimed at improving daily life functioning for people with MS who are experiencing cognitive difficulties. The COB-MS has undergone extensive feasibility testing and has been found to be both feasible and acceptable by clinicians and participants with MS. The aim of this research is to estimate the clinical and cost-effectiveness of the COB-MS intervention relative to a treatment-asusual control group. This study is a single-blind, three-arm, pragmatic randomised trial with two SWATs. We will establish the effectiveness of both online and in-person delivery of the COB-MS, relative to control condition. This will be achieved through five separate work packages (WP), and follow FAIR data management principles: " WP1: Internal Pilot Phase. " WP2: Evaluation of the clinical effectiveness of the COB-MS through quantitative and qualitative outcomes. " WP3: COB-MS cost-effectiveness analysis. " WP4: Process Evaluation. " WP4: Two SWATs focused on core outcome set development and retention to be carried out in conjunction with the main trial. This definitive trial, and associated SWATs, are led by the needs of the MS community at national and international levels and have a strong PPI-focus throughout. This research is innovative and very timely and links with priority research areas in multiple sclerosis rehabilitation, occupational therapy, and trial methodology, ensuring the international relevance of the research to the MS rehabilitation research community, knowledge-users, and those living with MS. The COB-MS team consists of experts in multiple disciplines, trial methodology, health economics, statistics, health service research, and related disciplines.

Project Title
 Multi-National Implementation of Multimodal Strategies to promote Healthy Brain Ageing in Sub-Saharan Africa (The AFRICA-FINGERS Project)
From
30 April 2024
To
29 April 2029
Summary
Given unprecedented expansions in aged populations globally, cognitive impairment and dementia present significant challenges for healthy longevity. More than half of all dementia patients (>60%) are living in low- and middle-income countries (LMICs). LMICs, like Sub-Saharan Africa (SSA) are fast-aging societies facing the dementia epidemic already, with cases projected to rise to 357% in the next two decades. The burden will be insurmountable in the coming years if preventive measures are not found and applied. Encouraging reports from the Lancet Commission on Dementia Prevention, Intervention, and Care estimates up to 40% of dementia as preventable. Risk reduction strategies simultaneously targeting multiple risk factors have been proposed by the World Health Organization (WHO) as optimal prevention approaches. One such successful strategy is the landmark Finnish Geriatric Intervention Study to Prevent Cognitive Impairment and Disability (FINGER) multimodal lifestyle modification trial that demonstrated improvements in cognitive and health outcomes 2-years post-intervention. Researchers globally are adapting and implementing this approach, within a World-Wide network (led by study co-CI, with the international efforts for bio-specimen repository led by this study's CI), but not yet in Africa. Therefore, we propose a multi-national collaboration towards brain health promotion in SSA: The AFRICA FINGERS Program. AFRICA-FINGERS represents the first attempt to coordinate and implement culturally informed multidomain dementia-risk reduction interventions across SSA, with sustainability goals embedded within the initiative. The overarching aim of our proposal is to reduce cognitive impairment and promote healthy aging in African populations by optimizing the management of core modifiable risk factors identified by the Lancet Commission on prevention, the WHO policy for addressing NCDs and, by members of our teams working within these indigenous populations as well as, crucially, the indigenous community members themselves. Here we propose two primary objectives: A) To co-design with local stakeholders a bespoke personalized multidomain lifestyle dementia risk-modification protocol, and collect data on intervention effectiveness, bio-mechanisms and cost-effectiveness. We are proposing to identify and test solutions that are contextually and culturally appropriate, economically viable, and sustainable. B) To promote sustained efficacy of the intervention and scalability via community-wide implementation and harmonize methods for adoption in partner countries and across similar demographics. AFRICA-FINGERS is a multinational brain health promotion initiative (at-risk adults >50years, n=600) set within established academic research infrastructures with already-phenotyped cohorts in Kenya and Nigeria. The program will be nested within the WW-FINGERS framework, with the central hub at the Brain and Mind Institute (BMI), Aga Khan University in Nairobi, Kenya. The BMI addresses acute and rising gaps in research capacity and interventions for mental and neurological conditions in Kenya. Given the BMI Vision and Values, diverse and relevant expertise of its members, its location and connections, including a registered Clinical Trials Unit, Lab facility and Imaging core; the BMI is ideally suited as the central hub for AFRICA FINGERS and its primary site. The secondary sites are Department of Public Health, Kilifi county, Kenya; University of Lagos, Nigeria and The Research Centre for Ageing Cognition and Psychological Health, Nnamdi Azikiwe University (NAU) Awka, Nigeria; all conducting dementia clinical studies. Guided by the MRC/NIHR framework for complex interventions, this collaborative project will partner with WW-FINGERS, Davos Alzheimer's Collaborative, Global-Brain-Health-Institute, Global-Dementia-Prevention-Program, Neurovision, Oasis Diagnostics, Alzheimer's Disease Data Initiative and Alzheimer's Disease International.

Project Title
 A randomised controlled pilot trial of psilocybin with psychological support for cocaine use disorder
From
01 December 2023
To
30 November 2026
Summary
Background: Cocaine use disorder has a detrimental impact on the individual, their families, and society. Psilocybin with psychological support, a synergistic combination of pharmacology and psychological support, is emerging as a multi-modal treatment paradigm that is showing therapeutic benefits for substance use disorders. Psilocybin activates cortical 5-HT2A receptors, induces transient alterations of brain connectivity in humans, and promotes synaptogenesis and neural plasticity in rodents. It is not yet known whether psilocybin with psychological support will play a therapeutic anti-addictive role in cocaine use disorder. Aim: Assess trial procedures to inform a future definitive trial of psilocybin with psychological support for cocaine use disorder. Methods: A 15-week randomised double-blind placebo-controlled pilot feasibility study of a single dose of oral psilocybin (25mg) or diphenhydramine 100mg (1:1) and 6 sessions of psychological support (3 preparation, 3 integration) will be conducted in 24 participants meeting DSM-5 criteria for cocaine use disorder (at least moderate severity) and who are seeking treatment. Participants will require a score of "4 on the Severity of Dependence Scale and self-reported cocaine use in the past month. Underpinned by the Medical Research Council Framework, the primary outcomes of this feasibility study will assess trial procedures to inform a definitive trial, determined by recruitment rates, adherence, retention, incidents/adverse events, and acceptability. Progression criteria, including a traffic light system of `stop", `change` and `go" thresholds will be used to facilitate decision-making for the definitive trial. The exploratory secondary outcomes will be cocaine use measured by the Timeline Follow-Back method (percentage days abstinent, complete/sustained abstinence, number of days to first use of cocaine after the drug administration session) verified by urine toxicology, selfreported cocaine craving assessed by the Cocaine Craving Questionnaire-Brief, and cocaine withdrawal using the Cocaine Selective Severity Assessment. Further exploratory measures will assess mood, anxiety, psychedelic experience, social connectedness and functionality using reliable and validated clinical measures. Conclusion: We envisage that this study will provide the necessary information to launch a definitive trial to determine whether psilocybin with psychological support can reduce cocaine use and craving and improve outcomes in treatment seeking adults with moderate to severe DSM-5 cocaine use disorder.

 Dementia Research Network Ireland (DRNI)
From
2022
To
2024
Summary
DRNI links leading researchers across several disciplines in the areas of dementia and ND, it is novel in its multi-disciplinary focus and strategic in its objective to enhance research co-operation and co-ordination across the island of Ireland. By facilitating collaborative consensus and policy based projects and supporting knowledge exchange and public patient events DRNI seeks to improve our understanding of the causes and mechanisms of dementia and neurodegeneration, the effectiveness of different models of care and the policy changes required to improve the quality of life for persons with dementia and neurodegenerative conditions and their caregivers. The inter-disciplinary nature of the network is highly innovative and reflects the emerging international evidence of the role of multi-modal influences on dementia and neurodegeneration. It reflects the network members" belief that the integration of knowledge and practice from diverse research traditions has the potential to radically improve our understanding of dementia and ND, in relation to prevention, care and quality of life. To further network objectives DRNI works collaboratively with the Structured Population and Health Services Research Education (SPHeRE) network which strives to increase cross-disciplinary interaction and collaboration in the area of population health and health services research. Combined the networks serve to act as a conduit to link researchers in the field of dementia and ND with statutory and non-statutory bodies, including, funding agencies, government, patient advocacy, charities, health service organisations, industries, and philanthropic organisations.
