Abstract
Background For the past five years, our annual reports have been tracking the clinical development of new drug-based therapies for the neurodegenerative condition of Parkinson's disease (PD). These reviews have followed the progress both of "symptomatic treatments" (ST - improves/reduces symptoms of the condition) and "disease-modifying treatments" (DMT - attempts to delay/slow progression by addressing the underlying biology of PD). Efforts have also been made to further categorize these experimental treatments based on their mechanisms of action and class of drug. Methods A dataset of clinical trials for drug therapies in PD using trial data downloaded from the ClinicalTrials.gov online registry was generated. A breakdown analysis of all the studies that were active as of January 31st, 2024, was conducted. This analysis involved categorizing the trials based on both the mechanism of action (MOA) and the drug target. Results There were 136 active Phase 1-3 trials evaluating drug therapies for PD registered on ClinicalTrials.gov, as of January 31, 2024. Of these trials, 76 (56%) were classified as ST trials and 60 (44%) were designated DMT. More than half (58%) of the trials were in Phase 2 testing stage, followed by Phase 1 (30%) and Phase 3 (12%). 35 of the trials were registered since our last report, with the remaining 101 trials appearing in at least one earlier report. Conclusions The drug development pipeline for PD remains in a robust state with a wide variety of approaches being developed and evaluated in Phase 1 and 2. Yet again, however, only a limited number of DMTs are transitioning to Phase 3.

Mucuna pruriens to treat Parkinson's disease in low-income countries: Recommendations and practical guidelines from the farmer to clinical trials. Paving the way for future use in clinical practice. Parkinsonism Relat Disord 2024; 124:106983. [PMID: 38797572 DOI: 10.1016/j.parkreldis.2024.106983] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/09/2024] [Revised: 04/24/2024] [Accepted: 04/27/2024] [Indexed: 05/29/2024]
Abstract
Parkinson's disease (PD) is a progressive and disabling neurodegenerative disease that rapidly worsens and results in premature mortality if left untreated. Although levodopa is the gold standard treatment for PD globally, its accessibility and affordability are severely limited in low- and middle-income countries worldwide. In this scenario, Mucuna pruriens (MP), a leguminous plant growing wild in tropical regions, emerges as a potential alternative or adjunct to levodopa-based medications due to its cost-effectiveness and global natural availability. Recent studies have demonstrated that MP can significantly ameliorate motor symptoms, although tolerability may vary. The proposition that MP could play a pivotal role in providing affordable and symptomatic relief for PD in low- and middle-income countries is grounded in its promising therapeutic profile, yet caution is warranted until more comprehensive data on the long-term safety and efficacy of MP become available. This manuscript summarizes the knowledge gained about MP by the authors, focusing on how to cultivate, store, and provide it to patients in the safest and most effective way in clinical trials. We aim to increase clinical trials investigating its safety and efficacy in PD, before promoting individual use of MP on a global scale, particularly in countries where availability and affordability of levodopa-based medications is still limited.

Abstract
Parkinson's disease (PD) is a global health challenge, yet historically studies of PD have taken place predominantly in European populations. Recent genetics research conducted in non-European populations has revealed novel population-specific genetic loci linked to PD risk, highlighting the importance of studying PD globally. These insights have broadened our understanding of PD etiology, which is crucial for developing disease-modifying interventions. This review comprehensively explores the global genetic landscape of PD, emphasizing the scientific rationale for studying underrepresented populations. It underscores challenges, such as genotype-phenotype heterogeneity and inclusion difficulties for non-European participants, emphasizing the ongoing need for diverse and inclusive research in PD.

Abstract
Allied health therapies refer to a range of healthcare professionals, including physiotherapists, occupational and speech-language therapists, who aim to optimize daily function and quality of life in conjunction with medical care. In this narrative review of literature on allied health therapies in people with Parkinson's disease (PD), we focused on the diversity in healthcare access, state of the art, current challenges in the African continent, and proposed solutions and future perspectives. Despite the increasing prevalence and awareness of PD in Africa, numerous challenges persist in its management. These include resource limitations, geographical barriers, sociocultural beliefs, and economic constraints. Nevertheless, innovative solutions, including telerehabilitation and community-based rehabilitation, offer hope. Collaborative efforts within the continent and internationally have shown potential in bridging training and resource gaps. Significant strides can be made with tailored interventions, technological advancements, and multifaceted collaborations. This review offers practical insights for healthcare professionals, policymakers, and caregivers to navigate and optimize PD care in the African context.
