Fatigue is one of the most common and the single most disabling symptom of multiple sclerosis (MS). However, there is a lack of consensus on the most appropriate fatigue measures in clinical practice and research, based upon rigorously validated, generalizable, and publicly available instruments. The objective of this research was to generate additional evidence regarding the validity and applicability of the PROMIS SF v1.0 - Fatigue (MS) 8a, including content validity, reliability, construct validity and responsiveness, as well as to assess minimal important difference (MID) estimates and a score interpretation tool to aide meaningful individual level score interpretation. A mixed-methods, sequential design was followed. Cognitive debriefing (CD) interviews (n=29) were performed with MS patients, to assess the relevance and comprehensiveness of the PROMIS Fatigue (MS) 8a scores. To evaluate the psychometric properties of the PROMIS Fatigue (MS) 8a, two observational studies were conducted: a cross-sectional study at two US MS centers (n=296), and a 96-week longitudinal study in a UK MS Register cohort (n=384). Main outcomes and measures were estimates of known-groups validity, convergence validity, reliability, and responsiveness, a guide for interpreting PROMIS Fatigue (MS) 8a T-scores, and anchor-based MID estimates. The CD interviews confirmed the comprehensiveness and relevance of the PROMIS Fatigue (MS) 8a in assessing MS fatigue. Cronbach's alpha (>0.9) and intra-class correlation coefficient (≥0.9) for test-retest scores at 5-7 days follow-up, supported strong internal consistency and test-retest reliability. Hypothesized differences were found across patient groups in patient reported fatigue and related concepts (analysis of variance [ANOVA], P <0.001). PROMIS Fatigue (MS) 8a scores were sensitive to bi-directional changes in fatigue (GHS fatigue global question) and physical health (PROMIS GHS GPH), over a 52-week follow-up. Score changes of 3.4-4 points are proposed as MID criteria for minimal improvement or worsening in fatigue. This research extends the evidence supporting the content validity and the robust psychometric performance of the PROMIS Fatigue (MS) 8a across US and UK MS populations. Importantly, data supporting the measure's integration in clinical practice and research, including meaningful score interpretation, are now available.

Seven national medicines regulatory authorities in the East African Community (EAC) have embraced regulatory reliance, harmonization and work sharing through the EAC Medicines Regulatory Harmonization programme. Measuring the performance of regulatory systems provides key baseline information to build on regulatory system-strengthening strategies. Therefore, the aim of the study was to evaluate the regulatory performance of the EAC joint scientific assessment of applications approved between 2018 and 2021. Utilising a data metrics tool, information was collected reflecting timelines for various milestones including submission to screening, scientific assessment and communication of regional recommendations for biologicals and pharmaceuticals that received a positive regional recommendation for product registration from 2018 to 2021. Several challenges as well as possible solutions were identified, including median overall approval times exceeding the EAC 465-day target and median times to issue marketing authorisation following EAC joint assessment recommendation that far exceeded the 116-day target. Recommendations included establishment of an integrated information management system and automation of the capture of regulatory timelines through the EAC metric tool. Despite initiative progress, work is required to improve the EAC joint regulatory procedure to achieve regulatory systems-strengthening and ensure patients' timely access to safe, efficacious and quality medicines.

Background: For almost a decade, the East African Community has implemented the Medicines Regulatory Harmonization (EAC-MRH) programme among its member states to harmonise technical requirements and standards for medical products regulation, jointly conduct scientific review of medical product dossiers to assess safety, efficacy and quality, inspect pharmaceutical manufacturing sites and streamline decision-making processes. This initiative enables the cost-effective use of limited resources and efficient and effective delivery of regulatory services to be determined, thus instilling transparency and accountability in all stakeholders, optimising the pharmaceutical market and economic development and improving access to safe, high-quality, effective medicines in the region. The aim of this study was to evaluate the effectiveness and efficiency of the current operating model of the EAC-MRH initiative, including challenges faced and to identify opportunities for improvement.Methods: The Process Effectiveness and Efficiency Rating (PEER) questionnaire, which was used to identify the benefits, challenges, and suggestions for improving performance of EAC-MRH initiative, was completed by assessors representing seven EAC authorities in the joint assessment procedure. Semi-structured interviews were also carried out to validate the responses.Results: This initiative has been of considerable value as it moves toward achieving its main objectives of shorter timelines for approval of medicines, information sharing among regulators and capacity building for assessments, resulting in quicker access and increased availability of medicines for patients in the region. However, the key challenges identified that have hindered effectiveness and efficiency were the lack of a centralised submission and tracking system; inadequate human resources, manufacturers’ failure to submit the exact same dossier to all countries of interest; lack of an integrated information management system; lack of information on national medical regulatory authority or EAC websites; and challenges in monitoring and tracking assessment reports.Conclusion: The use of a robust information technology system for the central tracking of EAC products is essential to address the identified challenges and improve regulatory effectiveness and efficiency. One central point for payment is needed to expedite the process and to ensure transparency and the availability of information on decision making on national and regional websites. Other key strategies for enhancement include improving the capacity of assessors, work and information sharing and a coordination mechanism for the regional joint assessment, with the eventual establishment of a regional medicine agency.
