There are many challenges in developing effective treatments for neurodegenerative diseases like Parkinson's and Alzheimer's. Regulatory agencies in the US and EU play a significant role in determining the efficacy and safety of drugs used to treat these conditions. However, the approval process is convoluted and frequently encounters obstacles that delay timely access to critically needed treatments. This thesis seeks to identify, examine, and suggest potential remedies for the problems regulatory bodies in both regions encounter. Through an extensive review of the literature, regulatory standards, and case studies, the thesis looks at the major challenges encountered throughout the drug approval process for Parkinson's and Alzheimer's diseases. Scientific roadblocks including the complexity of disease mechanisms and the lack of knowledge of sickness progression make it difficult to show therapy efficacy and choose the appropriate patient populations. Clinical issues arise from the diversity of the patient population, the dearth of reliable biomarkers, and the need for precise long-term data for therapy benefit assessment.
Regulatory impediments are procedures and rules that differ between the US and Europe. These include changes to regulatory structures, clinical trial designs, and data requirements. Regulatory standards must be standardised, regulatory authorities must collaborate more closely, and data requirements must be uniform to expedite the clearance process and guarantee universal access to medications.
The thesis offers various strategies that regulatory agencies, pharmaceutical companies, and researchers can use to get around these challenges. Greater stakeholder collaboration and data sharing can promote the pooling of knowledge and resources, which will lead to more thorough clinical research and better outcomes. Adaptive trial designs and master protocols are examples of cutting-edge trial designs that can aid in patient recruitment and data collection. Utilising patient registries and actual data can speed up the approval procedure and provide more information about the results of treatment. To align expectations and proactively resolve regulatory concerns, early communication between regulatory organisations and drug developers is crucial. [...]

Objectives and Research Scope
This thesis aims to analyze the regulatory challenges surrounding the approval of pharmacological treatments for Parkinson's and Alzheimer's diseases in the United States and Europe. The research examines why these drug classes often encounter significant obstacles during the regulatory process and how regulatory agencies can implement more effective strategies to expedite access while ensuring patient safety.
- Comparison of regulatory standards between the USFDA and EMA for neurological drug approvals.
- Identification of primary scientific and clinical barriers, such as lack of biomarkers and endpoint consensus.
- Review of current pharmacovigilance methods and post-market surveillance for neurodegenerative drugs.
- Analysis of the economic and social impact regarding treatment availability and patient quality of life.
- Exploration of innovative strategies, including adaptive trial designs and accelerated approval pathways.
Excerpt from the Book
1.3 Parkinson disease
PD was first described in 1817 by James Parkinson and described it as ‘An Essay on the Shaking Palsy’ in which he took six patients, out of six – three he personally did examination closely whereas other three were picked randomly from streets of United Kingdom for examination and comparison. The ‘shaking behaviour’ was called as a combination of different tremor, lessened muscular power, abnormal truncal posture and, propulsive gait. PD is the second most common neurodegenerative disorder after Alzheimer disease (AD) (Madaule & Axel, 1985, Etienne-Manneville et al, 2002). It is characterized clinically by bradykinesia and other cardinal motor features, and pathologically by neuronal loss in the substantia nigra (SN) and widespread accumulation of intracellular -synuclein protein, also known as Lewy bodies. Usually, PD is seen in 5 % of humans over 60 years of age and is main common in men related to women. Till date there is no cure or treatment plans available for PD or any of the other age-related neurodegenerative disorders. Drugs available in market just manage the symptoms, It is said that by 2030, population of PD will be doubled than the population of PD is today (Madaule & Axel, 1985, Bonifacino and Glick, 2004, Zerial et al, 2001).
