Periodic Reporting for period 2 - PROMINENT (PRECISION MEDICINE PLATFORM IN NEURODEGENERATIVE DISEASE)
Periodo di rendicontazione: 2024-05-01 al 2025-04-30
PROMINENT has conducted a Europe-wide survey among specialist physicians on their views on what functionality should be included in a clinical decision-support system, and what value this would bring in clinical practice. These results have now been published (https://pubmed.ncbi.nlm.nih.gov/39999809(si apre in una nuova finestra)) and were used to inform next steps of the project. During the first two years of the project, PROMINENT has made important additions to the digital platform, including functionality for automated analysis, interpretation and reporting of MRI, PET and DaTSCAN images, including features of importance for selecting patients for AD DMT and monitoring potential side effects from these treatments.
PROMINENT has also made progress on developing novel prediction models for differential diagnosis and prognosis, which will later be added to the platform. A literature review on existing multimodal prediction models has been published (https://pubmed.ncbi.nlm.nih.gov/40567069(si apre in una nuova finestra)) we have established the data management and sharing procedures within the consortium and created a database with harmonized datasets from project partners.
Two prospective clinical studies have been initiated, with focus on demonstrating the clinical value of the decision support system through increasing diagnostic confidence and optimizing the efficiency of the diagnostic process in terms of resource use, costs and time.
Additionally, the project aims to deploy the system so that new DMTs for AD can be introduced. In anticipation of the introduction of new DMT, the consortium has consulted key stakeholders on what evidence will be required to support decisions on pricing, reimbursement and implementation. Based on the results we have prepared an approach to collecting and analysing data on new treatments as they are being introduced in routine care, to meet the requirements by payers and other health care decision makers.
A key factor for the project success is the meaningful involvement of patients and their caregivers in the majority activities across PROMINENT. The project has established a Public Involvement board and held two online consultations during the second year of the project. Patients and caregivers have been consulted to review and comment on project deliverables, and their feedback is considered in subsequent updates.
Moreover, the project has made an impact on clinical use as automated tools for analysing diagnostic images have been introduced. This includes magnetic resonance imaging (MRI), positron emission tomography (PET) and dopamine transporter imaging (DaTSCAN). The system has already received positive feedback about the new features and products.
The project also developed a process for capturing RWE from the digital platform to evaluate the usage, safety, effectiveness and cost-effectiveness of disease-modifying therapies for AD.
The evaluation and validation studies will majorly contribute to the quantification of project impact on the diagnostic and prognostic precision by 1) providing data on the usability of a CDSS and how it supports clinicians in the diagnostic process, 2) analysing the impact of the CDSS on diagnostic confidence and assessment of DMT eligibility, and 3) analysing the prognostic accuracy of the CDSS after one year.
The study design of the validation study has been carefully developed to be able to compare time and monetary resources required for the diagnostic pathway with and without use of the CDSS, thereby delivering estimates on potential savings in resources due to “unnecessary” diagnostic procedures without reducing diagnostic accuracy. This research on optimal diagnostic pathways is of major importance due to limited capacities of specialized memory clinics in the face of an increasing rate of older individuals in European societies, thereby combining both economic and societal impacts.
In addition, the relevance of efficient identification of individuals who are eligible for DMTs will increase further once DMTs become available in Europe. The validation study has been designed in a way to contribute toward the project’s impact on optimized introduction of DMTs and potential reduction of CSF tests. The protocol for both studies have been published, and submissions for research ethics review have been completed.
