Do you know, according to clinicaltrials.gov, a total of 354,130 clinical trials were registered worldwide with 71,256 ongoing clinical trials as recorded on Oct-2020? The number of clinical trials is increasing year by year from 56.16k in 2017 to 60.69k in 2018. In the USA, more than 2.3+ million people participate in approximately 80,000+ clinical trials every year.<\/p>\n\n\n\n

Chronic diseases such as heart disease, stroke, cancer, respiratory diseases, and diabetes are the leading causes of mortality in the world and represent 63% of all deaths. Chronic disease projected will account for seven out of the top 10 causes of death in the world by 2030. The sites and investigators working in these therapeutic segments are available widely all over the globe.<\/p>\n\n\n\n

The statistics show that the number of new cancer cases around the world was expected to increase from 12.7 million in 2008 to 21 million by 2030. About 350 million to 400 million people worldwide have a rare disease. In the US, 25 million to 30 million people are affected. Over 45 million people in Asia may be suffering from a rare condition. In China alone, 20 million people may be affected.<\/p>\n\n\n\n

Now, most of the research and pharma companies are focusing on innovative cancer treatment and treatments for rare diseases. The demand for sites and investigators is increasing by folds globally. <\/p>\n\n\n\n

What are the most retarding factors for clinical trials globally<\/h2>\n\n\n\n

Globally most of the clinical trials fail in completing the study in time, and the following is the scenario of most of the clinical studies, irrespective of regions.<\/p>\n\n\n\n

    \n
  • 45% of clinical trials are delayed<\/li>\n\n\n\n
  • 70 % of clinical trials face study start-up delays<\/li>\n\n\n\n
  • 80-90% of clinical trials fail in the recruitment of patients<\/li>\n<\/ul>\n\n\n\n

    Patient recruitment is a nightmare for many researchers and is the leading cause of study delays. The main reason for recruitment delays are due to<\/p>\n\n\n\n

      \n
    • Inability to select perfect sites.<\/li>\n\n\n\n
    • Uncertainties in estimation of the number of patients from sites-\u00a0<\/li>\n\n\n\n
    • Improper estimation of time required for patient enrollment.<\/li>\n\n\n\n
    • The protocol design.<\/li>\n\n\n\n
    • The competitive landscape.<\/li>\n<\/ul>\n\n\n\n

      You can address these issues, to some extent, by choosing the right site for your clinical trials. Therefore, selecting the perfect site becomes a critical part of the process. Conducting clinical trial feasibility can help sort this out.<\/p>\n\n\n\n

      How can you choose the best sites for your clinical trials?<\/h2>\n\n\n\n

      There are many ways to find the right sites for your clinical trials, but the most modern and efficient way of identifying the clinical trial sites in conducting feasibility. It may just take a few hours to days based on the type of feasibility and outcome you are looking for. <\/p>\n\n\n\n

      The basic steps involved in choosing the right site includes<\/p>\n\n\n\n

        \n
      • Establish the study requirements you’re looking for<\/li>\n\n\n\n
      • Conduct feasibility to explore the sites and investigators<\/li>\n\n\n\n
      • Evaluate and finalize the most promising sites that match your study requirements.<\/li>\n<\/ul>\n\n\n\n

        Clinical trial sites and investigators in North America<\/h2>\n\n\n\n

        Most of the clinical trials in the world are happening in North America. This is due to its precise regulatory structure. There is also greater clinical trial awareness among populations and thus patient recruitment rates are higher. Study timelines are quicker. A good number of clinical research sites are scattered across the geography.<\/p>\n\n\n\n

        Clinical research sites in North America, including the USA and Canada, are recognized as some of the most advanced in the world. Many of these sites have developed the infrastructure and resources necessary to conduct clinical research.<\/p>\n\n\n\n

        Advantages of sites and investigators from North America<\/h4>\n\n\n\n
          \n
        • Have a wide range of sites right from academic clinical research facilities to physicians clinics.<\/li>\n\n\n\n
        • Experienced investigators in wide therapeutic and sub-therapeutic areas<\/li>\n\n\n\n
        • Good patients recruitment and retention rates and availability of various resources and mediums for recruiting.<\/li>\n\n\n\n
        • Availability of many rare diseases and oncology sites.<\/li>\n\n\n\n
        • Most sites have faster trial initiation, recruitment timelines, and almost reach the predetermined study completion timelines.<\/li>\n\n\n\n
        • The majority of sites are \u201cgood sites\u201d<\/em><\/li>\n\n\n\n
        • Great importance to the protection of intellectual property (IP) rights,<\/li>\n<\/ul>\n\n\n\n

          Disadvantages<\/h4>\n\n\n\n
            \n
          • Costs associated with sites in conducting clinical trials is high compared to the developing countries.<\/li>\n\n\n\n
          • Stringent regulatory process and formalities.<\/li>\n\n\n\n
          • Timeframe delays in a few cases of clinical trials<\/li>\n\n\n\n
          • Trial sites require to follow not only federal laws but also states and regional policies and this may be even worse in multi-regional trials.<\/li>\n<\/ul>\n\n\n\n

            The other regions in North America are improving the scenarios of performing clinical trials and are coming into the limelight in recent years. <\/p>\n\n\n\n

            Clinical trial sites and investigators in Europe<\/h2>\n\n\n\n

            In the EEA (European Economic Area), authorities authorize approximately 4,000 clinical trials each year. This results in roughly 8,000 clinical trial applications, as each trial typically involves two Member States. The pharmaceutical industry sponsors about 61% of these clinical trials, while non-commercial sponsors, such as academia, initiate the remaining 39%.<\/p>\n\n\n\n

            Europe\u2019s top five countries for healthcare markets include Germany, France, Italy, the UK, and Spain, with Germany being a potential market for clinical trials. It is ranked second in the world and first in Europe for the number of active clinical trial sites, with over 22,000 active clinical trial sites.<\/p>\n\n\n\n

            Europe has presented continuous competitiveness to the top regions like North America and Asian countries for conducting clinical trials.<\/p>\n\n\n\n

            Advantages of clinical trial sites in Europe <\/h4>\n\n\n\n
              \n
            • The primary reason for conducting trials at clinical sites in Europe is that authorities approve study protocols more quickly. European sites are also likely to finish before U.S. sites even begin.<\/li>\n\n\n\n
            • Considering the study costs which fall into three categories monitoring and contract research organization (CRO) costs, investigative site costs, and ethics committee costs. The monitoring and CRO costs are generally less than those with costs in the United States,<\/li>\n\n\n\n
            • There are countries in Europe where sites and investigators are more eager to participate in a study compared to other regions, and it is obviously wise to choose a region where investigators and sites are generally enthusiastic to take part in the clinical research.<\/li>\n\n\n\n
            • Most of the sites in the European countries have fewer start-up timelines and good recruitment speed<\/li>\n\n\n\n
            • Support regulatory environment<\/li>\n<\/ul>\n\n\n\n

              An example of costs involved in Europe<\/h4>\n\n\n\n

              Monitoring for a 20-subject study was bid at $133,000 by a U.S. CRO; the same study was bid at $45,000 by a Dutch CRO. The Ethics committee costs run about the same as U.S. IRB costs, approximately $2000 per study. <\/p>\n\n\n\n

              Clinical trials sites and investigators in the Asia Pacific and other regions<\/h2>\n\n\n\n

              <\/text><\/path>A study shows that clinical trial recruitment has increased in Asian-Pacific countries more than in regions like Europe and North America over the last decade. <\/p>\n\n\n\n

              The study also shows that major annual increases in clinical trials were seen in the Asian countries like Iran, China, and India. Asian countries have a large patient population naive and this makes these regions preferable for performing clinical research with other additional advantages like costs. <\/p>\n\n\n\n

              Asia-Pacific has a growing number of experienced investigators.  As of 2019, there are over 43,000 active principal investigators (PIs) across Asia-Pacific markets, which is comparable to North America.<\/p>\n\n\n\n

              However, the pediatric population did not see this increase, likely because parents were reluctant to have their children participate in clinical trials. Additionally, a lack of clinical trial awareness, restrictive regulatory oversight, and ethical factors contributed to the lower participation.<\/p>\n\n\n\n

              The rise in interest for Asian countries are attributed due to the following reasons<\/p>\n\n\n\n

                \n
              • Presence of heterogeneous population groups\u00a0<\/li>\n\n\n\n
              • Availability of a large number of treatment na\u00efve patients<\/li>\n\n\n\n
              • High incidence of some diseases in Asian and other regions other than Europe and North America<\/li>\n\n\n\n
              • Low cost associated with conducting clinical trials in regions like Asia, Africa, etc.<\/li>\n\n\n\n
              • Low-density clinical trials performed providing a less competitive\u00a0environment for sites and principal investigators<\/li>\n<\/ul>\n\n\n\n

                Examples of choosing countries <\/h4>\n\n\n\n

                Most of the pharma companies would prefer to carry out drug trials for the treatment of liver cancer or gastroesophageal cancer in Korea or China, as these countries provide a large pool of patients naive for conducting clinical trials in these diseases.<\/p>\n\n\n\n

                Advantages of sites and investigators from the rest of the world<\/h4>\n\n\n\n
                  \n
                • Low costs are associated with clinical trial conduction. The major cost drivers include staff and admin, clinical procedures, site monitoring, and site retention, which are attributable to being low in Asian-Pacific countries and other regions. <\/li>\n\n\n\n
                • Improving clinical research site in fractures and following international standards to manage large clinical trials.\u00a0<\/li>\n\n\n\n
                • Diverse ethnic population for patient recruitment<\/li>\n\n\n\n
                • Improving regulatory approval timelines for example\u00a0 China, where regulatory timelines have decreased by 16 months since 2016<\/li>\n\n\n\n
                • Asia-Pacific countries are also becoming more diligent in developing regulatory regimes that protect intellectual property (IP) rights and stringent policies at research sites,\u00a0<\/li>\n\n\n\n
                • Countries from regions like Asia-Pacific demonstrate clinical trial compliance levels equivalent to Europe and North America.<\/li>\n<\/ul>\n\n\n\n

                  Disadvantages<\/h4>\n\n\n\n
                    \n
                  • The uncertain regulatory environment and ethical challenges\u00a0\u00a0<\/li>\n\n\n\n
                  • Infrastructural challenges with the site of few countries<\/li>\n\n\n\n
                  • Diverse language barriers and requirements of information to be presented in regional scripts at the site.<\/li>\n\n\n\n
                  • Not well-structured patient recruitment policies implemented at sites.<\/li>\n<\/ul>\n\n\n\n

                    COVID and clinical trials sites<\/h2>\n\n\n\n

                    Due to the COVID pandemic, the pharma industry is focusing more on COVID and infectious disease-related research. As a result, more COVID-19 clinical trials are being planned and initiated, while a large number of clinical trials for non-COVID-19 indications are facing delays.<\/p>\n\n\n\n

                    Many regulators such as EMA, FDA, TGA are offering accelerated approval for Covid-19 therapeutics and vaccines and this made the sponsor shifting their focus towards COVID and COVID-related trials. However strategically some of the pharmaceutical companies have announced disruptions in planning and ongoing trials, postponing trial start dates, and halting subject enrolment.<\/p>\n\n\n\n
