In the twenty-first century, the world has been dealing with large outbreaks of infectious diseases, which have not only affected public health but have also posed challenges to health security, biodefense, and the global economy. From the outbreak of SARS in 2002 to the ongoing fight against COVID-19 and recent cases of Monkeypox, the need for prompt prevention and control measures against epidemic viruses has become effectively obvious. The worldwide clinical trial landscape for infectious diseases has seen a significant spike in activity over the last five years, with around 7,000 industry-initiated studies spanning varied geographies, with nearly equal distribution between the Asia-Pacific (APAC) and Western regions. This represents a concerted worldwide effort to develop medical knowledge and prevent infectious diseases.
The infectious disease clinical trial landscape has seen rapid expansion, registering high compound annual growth rate (CAGR) numbers from 2018 to 2022. The number of trials worldwide rose from over 700 in 2018 to more than 1,000 by 2022. This escalation demonstrates the global community's commitment to addressing infectious diseases holistically and developing viable solutions. Mainland China, the EU5 countries, and the United States have emerged as major centres for infectious disease research and clinical trials. These areas have demonstrated their dedication to furthering our understanding of infectious diseases and delivering novel therapies.
An overwhelming number of these clinical trials have focused on viral infections, which have gained prominence in recent years as a result of the COVID-19 pandemic. COVID-19, HIV, hepatitis, RSV, Zika, and Ebola are among the viral targets, with Asia leading the way in this area. Bacterial infections, which are exacerbated by antibiotic resistance, as well as fungal and protozoan infections, have received significant attention in clinical research. Small molecules have typically dominated these studies, but biologic medicines are gaining ground. Vaccines and monoclonal antibodies have shown significant promise as top biologic modalities, and there is considerable interest in advanced technologies such as mRNA and siRNA therapeutics, particularly in light of the extraordinary speed with which COVID-19 mRNA vaccines were developed.
The Asia Pacific region has succeeded not just in the sheer volume of studies, but also in patient recruiting, offering shorter enrollment durations. This competitive edge has sped up the gathering of essential data and expedited the development of therapies and vaccines. Vaccine R&D activities are centered globally, with the United States leading the way with over 400 vaccine candidates, closely followed by China with 300+ and Europe with about 200. This focus emphasizes the need for a global coordinated effort to address the constant evolution of infectious diseases.
Venture capital financing has been critical in advancing global infectious disease clinical research and development. Funding estimates have risen significantly, rising from $2.8 million through 81 deals in 2018 to around $4 million over 96 deals in 2022. The United States and China have emerged as leaders in garnering such financing, maintaining their pivotal roles in the global landscape of infectious disease research.
To summarize, the worldwide clinical trial landscape for infectious diseases has seen significant development and transformation during the last five years. The COVID-19 pandemic has boosted research efforts and underlined the crucial significance of worldwide collaboration in effectively combating infectious disease threats. Staying updated about current trends, regional disparities, technological developments, and financing dynamics is critical for defining best practices in trial execution and strengthening our collective defences against infectious diseases.
