Introduction to Regulatory Affairs and Different Regulatory Bodies for Pharmaceutical Products and Impact of Digitalization on Regulatory Affairs ()
1. Introduction
The regulatory affairs (RA) field is concerned with the regulatory requirements for pharmaceutical product marketing authorization. Regulatory affairs professionals mediate the interaction between regulators (the government), the regulated [industry], and the market (consumers) to get good products to market and maintain them there while preventing poor quality and efficacy products from being sold. On the industry side, regulatory affairs professionals collaborate with research scientists, physicians, manufacturing organizations, and sales and marketing teams to ensure that the government gets the information it requires to evaluate a product. People in regulatory affairs work for the government to interpret and enforce laws passed by Congress to safeguard the public. People in regulatory affairs help keep the other two groups honest, and they provide the impetus for Congress to pass rules that control how the government and industry treat products. Basically, RA acts as an intermediary between the pharmaceutical sector and drug regulatory authorities globally. It primarily focuses on the registration of pharmaceutical goods in their various nations prior to marketing.
Recently, there has been a rise in the involvement of patients in all areas of drug development, including regulatory review, which has impacted medical product regulation [1] . Because of speedier clinical trials, drugs will be able to reach the market at an earlier stage of development, leading regulators to lay a larger emphasis on post-market oversight. To increase efficiencies at this level of development, the clinical trial business is incorporating more modeling, newer statistical methodology, and artificial intelligence [2] [3] . Furthermore, regulatory agencies are collaborating more and adopting work-sharing, dependence, and cooperative reviews to facilitate the review of these novel items entering the regulatory system [4] [5] . All of these developments necessitate a workforce that is adaptable, technologically proficient, and capable of learning and adapting work practices to suit these new trends. This article will look at the many factors influencing the development of novel therapies for disease relief and how these developments affect the function of the regulatory bodies and regulatory affairs professional.
2. Key Regulatory Agencies
Some of the international regulatory agencies and organizations that play an important role in all aspects of pharmaceutical regulations include the World Health Organization (WHO), Pan American Health Organization (PAHO), World Trade Organization (WTO), International Conference on Harmonization (ICH), and World Intellectual Property Organization (WIPO).
The key problems for these regulatory authorities and organizations worldwide are to ensure the safety, quality, and efficacy of medicines and medical devices, to harmonize legislative procedures connected to drug development, and to monitor and ensure compliance with statutory requirements. They also play an important role in ensuring and increasing regulatory implementation in non-regulated areas of the world to protect the safety of those who live there.
The major challenges for these regulatory bodies are: 1) Promoting public health and protecting the public from harmful and dubious drugs; and 2) Establishing proper legalization covering all products with a medicinal claim and all relevant pharmaceutical activities, whether carried out by the public or private sector. 3) Increase global regulatory growth to ensure people’s safety. 4) Centralization of the regulatory process and control.
3. National Regulatory Bodies
The regulatory body ensures compliances in various legal and regulatory aspects of a drug. Each country has its own regulatory body which controls the registration and marketing of the medicinal products at the national level. That national level regulatory body governs the rules and regulations. Additionally, it issues the guidelines for the drug development, licensing, registration, manufacturing, marketing, and labelling of the pharmaceutical products. USFDA (USA), MHRA (UK), TGA (Australia), CDSCO (India), DRAP (Pakistan) HEALTH CANADA (CANADA), MCC (South Africa), ANVISA (Brazil), EMEA (European Union), NMPA (China), NAFDAC (Nigeria), MEDSAFE (New Zeeland), MHLW (Japan), HAS (SINGAPORE) MCAZ (Zimbabwe), SWISSMEDIC (Switzerland), KFDA (Korea), are the few regulatory agencies and organizations established in respective countries [6] .
4. Key Trends and Global Problems
Getting the better understanding of the sole global trends can positively help the regulatory affairs professionals to predict the future impact on their role and responsibilities. Recently, the key global trends have been updated by the (CSIRO) Commonwealth Scientific and Industrial Research Organization, and enlisted adapting to changing environment, diving into digital dimension cleaner and greener, increasingly autonomous, unlocking the health imperative, and unlocking the human [7] . Such major developments have the potential to influence the future of medicine, therapeutic product development, and the way regulatory professionals do their work. Concerns about climate change are influencing manufacturing, with an emphasis on sustainable methods, reduced environmental effect, and a shift towards a circular industrial economy [8] . The increased push by countries to manufacture vital pharmaceutical items locally, in response to the COVID-19 pandemic, reflects geopolitical instability [9] . The COVID-19 pandemic has emphasized the dangers of infectious diseases, which are expected to worsen because of climate change. Antimicrobial resistance, an ageing population’s growing chronic health burden, increased pressures on mental health, and budget limits on healthcare spending will all have an impact on the pharmaceutical industry. More optimistically, the prospect of precision medicine, more digital connectivity across the healthcare system, a shift towards a learning healthcare system, and an emphasis on wellbeing and preventative medicine will lead to future healthcare advancements as well as possibilities for industry [10] [11] [12] . The evolution of harmonization, convergence, and reliance has led to the establishment of a work-sharing arrangement known as the ACCESS Consortium. This arrangement involves comparable, mid-sized national regulatory authorities from Australia, Canada, Singapore, Switzerland, and the United Kingdom. Additionally, these countries are active partners in Project ORBIS. The practice of work sharing has evolved over time through the establishment of robust information sharing mechanisms and the cultivation of trust among participating regulatory bodies. This has led to a system where these regulatory authorities divide the review of Modules, while adhering to confidentiality agreements and memorandum of understanding that have been mutually agreed upon. Each participant maintains their individual autonomy in decision-making; however, the process alleviates the burden on regulators and facilitates the exchange of expertise across various geographical regions.
5. Digital Disruption
The drug development process is increasingly being affected by digital disruption, which encompasses several stages such as early-stage discovery and validation of target molecules, optimization of candidate drug structure, manufacturing processes, and regulatory clearances by national regulatory bodies.
One of the primary difficulties encountered in the initial phases of drug development is the determination of the structure of target proteins, followed by the identification and optimization of suitable drug candidates capable of interacting with these proteins to impede or modify their functionality.
Artificial intelligence (AI) and machine learning (ML) are becoming a progressively significant role in the field of drug discovery [13] . The implementation of their application is expected to decrease the incidence of failure in the initial stages of drug research and development, while also expediting this phase in the overall process [14] [15] [16] . Additionally, it is expected to mitigate the potential hazards and financial burdens associated with the process of pharmaceutical development. Alphabet’s DeepMind AI demonstrated remarkable success in predicting the three-dimensional (3D) structure of many proteins during the biennial Critical Assessment of Structure Prediction (CASP) competition in both 2018 and 2020 [17] . Subsequently, DeepMind has made available an open-source AlphaFold protein structure database, which may be utilized by researchers and pharmaceutical developers to ascertain the three-dimensional configuration of prospective targets for the purpose of medication development [14] . In recent times, there has been an increased application of AI/ML systems, such as PandaOmics and Chemistry42, in the field of scientific research. These systems have been employed not only for the purpose of discovering new targets but also for speeding up identifying lead candidate molecules [15] [16] . To enhance trust in the use of AI/ML, it is imperative to build robust governance structures and ethical frameworks. Additionally, organizations that heavily rely on these systems must have well-defined quality assurance and auditing methods. Regulatory professionals must possess a high level of confidence in effectively communicating the intricacies of these technologies, guaranteeing their adherence to governmental regulations, and collaborating with regulatory authorities during the registration process of medicinal goods based on artificial intelligence and machine learning. Organizations must possess the capability to incorporate these systems into their established benefit-risk decision-making procedures and effectively convey this integration both internally and externally to relevant stakeholders.
Digital twins refer to virtual representations of physical assets or processes that possess the ability to accurately duplicate the behavior shown by the corresponding genuine as set or process [18] . The utilization of digital twins has the potential to enhance the efficiency of pharmaceutical manufacturing. This is achieved through the simulation of process flows prior to their implementation, which allows for the optimization of these processes. Additionally, digital twins facilitate technology transfer by enabling the testing of new manufacturing plants before their physical construction. Furthermore, personnel can receive training within the digital twin environment, preparing them for their roles within the actual manufacturing plant [18] [19] . Pharmaceutical corporations, such as GSK, have previously employed digital twin models to enhance the efficiency of their vaccine development and production procedures [20] .
An additional use of digital twins involves the simulation of disease progression. This advancement is expected to result in the establishment of digital twin control groups for use in clinical trials, therefore mitigating ethical and operational issues associated with traditional control cohorts [20] - [27] . With the proliferation of digital replicas of humans, there will be an enhanced capacity to forecast the effects of medicine prior to its administration to the patient. Consequently, the improvement of medication usage will be facilitated with the ability to test the most effective drug, dosage, timing, and method of administration in a person’s digital counterpart. This approach will effectively minimize the potential harm that a patient may encounter. The utilization of digital twins is expected to enhance the advancement of precision medicine [21] [22] and contribute to the increased implementation of “virtual” or “in silico” clinical trials, hence optimizing the efficiency of the clinical trials domain [23] .
The implementation of virtual or in silico clinical trials will have a significant impact on regulatory professionals, as ensuring the integrity of the data will become of utmost importance. The process of digitizing regulatory operations will be facilitated by various initiatives, including the adoption of the International Organization for Standardization’s (ISO) Identification of Medicinal Products (IDMP) standards. These standards necessitate the management of substance, product, organization, and referential [SPOR] data [24] .
The statement is based on the growing inclination towards structured data formats. This inclination facilitates the instantaneous transfer of data to national regulatory agencies through cloud-based systems like Accumulus Synergy. In the forthcoming years, there will be a growing reliance on data flows rather than document flows within the regulatory field. Consequently, regulatory professionals will need to enhance their digital literacy skills to effectively participate to these evolving data processes [25] [26] .
6. Global Regulatory Harmonization
Considering the progress made in the field of complex pharmaceuticals, regulatory bodies are displaying a growing inclination to collaborate through a range of techniques, including harmonization, convergence, dependence, collaborative review, and work-sharing. The global COVID-19 pandemic has further expedited this trend [27] [28] [29] . Harmonization refers to the procedure of incorporating both national and worldwide standards to enhance the effectiveness and streamline the global development and regulation of pharmaceuticals [30] . One notable illustration involves the incorporation of the International Council for Harmonization [ICH] standards by regulatory bodies at the national level [31] .
7. Digitalization of Regulatory Affairs
The different regulatory bodies are switching from paper based to eCTD submission. Various authorities have stopped accepting CTD (paper based) submissions. This step has been taken to centralize the process and also to speed up the process of submissions. The roadmap of the change in global regulatory Affairs to adopt digital adoption is mentioned in Figure 1. The transition from paper-based

to electronic Common Technical Document (eCTD) submission has had a significant impact on regulatory processes globally. The acceptance of eCTD format submissions has led to optimization of resources, increased efficiency, and improved tracking of applications during review [32] . This transition has also ensured that the content of submissions is consistent with global standards [32] . Practical examples of how eCTD submission is being implemented globally can be seen in various countries. For instance, in Japan, the Ministry of Health, Labor, and Welfare (MHLW) and the Pharmaceuticals and Medical Devices Agency (PMDA) have collaborated to enhance eCTD and e-clinical trials [33] . This initiative aims to support the development of new drugs through the electronic standardization of clinical trials [34] . Similarly, in the United States, the Food and Drug Administration (FDA) has implemented eCTD submission requirements for various types of applications, including new drug applications, biologics license applications, and abbreviated new drug applications [34] . The implementation of eCTD submission has had a positive impact on regulatory processes. Studies have shown that individuals with eCTD experience have been able to shorten their total time to approval and demonstrate cost savings compared to paper submissions [35] . This has been observed across different types of companies, regardless of their size or number of submissions [35] . Furthermore, the use of eCTD has facilitated the review and lifecycle management of electronic submissions, leading to harmonized electronic submission and review initiatives [36] The organized collection and storage of manufacturing information, including in-process release testing, specification testing, and batch release data, in a structured format within data lakes would enhance the ability to gather and share data to meet regulatory compliance needs [37] . The automation of eCTD compilation facilitates the more effective transfer of data into the current eCTD format for regulatory filings. At present, the process of eCTD creation necessitates human supervision and understanding of the information included within the papers. These documents are often in a portable document format (pdf), which lacks the capability to facilitate automated traceability to the original data sources or enable data mining for enhanced insights [38] . The utilization of structured content and data management systems holds the potential to enhance the efficiency of data management processes, as well as facilitate the creation and dissemination of regulatory documents.
Until now, several organizations have been creating customized internal structured content management systems, specifically for clinical data. However, it is necessary for enterprises and regulatory bodies to adopt shared approaches to facilitate the efficient interchange of data and documents [25] [37] [38] . The ongoing development of initiatives such as Transcelerate’s Common Protocol Template and the FDA’s Knowledge-Aided Assessment and Structured Application (KASA) is contributing to the standardization of product quality/chemistry-manufacturing-controls (CMC) data. Additionally, the widespread adoption of the ICH Q12: Technical and Regulatory Considerations for Pharmaceutical Product Lifecycle Management guideline is also playing a role in promoting the use of more structured formats for both clinical and CMC data packages [37] [38] . The adoption of structured data formats for regulatory information will facilitate regulatory professionals in allocating additional time towards data analysis and the production of insights, specifically pertaining to the benefit-risk assessment of the product [38] . Simultaneously, the implementation of more systematic benefit-risk assessments by National Regulatory Authorities (NRAs) has the potential to enhance worldwide harmonization of benefit-risk assessment and establish a framework that can be integrated into health authorities’ benefit-risk algorithms [39] .
In conclusion, the transition from paper-based to eCTD submission has brought about significant improvements in regulatory processes globally. The acceptance of eCTD format submissions has optimized resources, increased efficiency, and facilitated tracking of applications during review. Practical examples of eCTD implementation can be seen in countries like Japan and the United States. The impact of eCTD submission has been demonstrated through shorter approval times and cost savings. Overall, the adoption of eCTD has led to harmonized electronic submission and review initiatives, enhancing regulatory processes in the pharmaceutical industry.
