GLOBALIZATION OF CLINICAL TRIALS<br />

To appropriately address some tumor subtypes, we will need<br />

trials that will screen very large populations to identify specifıc<br />

patients. Globalization not only addresses this challenging<br />

point, but also allows for subgroup comparisons and<br />

other inferences.<br />

What Are Some of the Advantages of Globalization of<br />

Clinical Trials?<br />

Conducting clinical trials in developing countries may facilitate<br />

local product approval, thereby generating local drug<br />

prescription more quickly. 11 At the same time, it is very important<br />

to consider that globalization of clinical trials not<br />

only benefıts the sponsor, but also global health. Expansion<br />

of clinical trials into developing countries brings new medical<br />

care options to subjects who may not even have the current<br />

standard of therapy available. In parallel, there are clear<br />

benefıts to the local medical community that has earlier access<br />

and exposure to new drugs and therapeutic advances.<br />

Involvement of investigators from developing countries in<br />

the planning phases of the trial is essential as they may provide<br />

valuable contribution while being exposed to an experience<br />

that will have long lasting effects in the future<br />

development of regional studies. Other than addressing a<br />

question that interests a pharmaceutical company, developing<br />

a reliable research infrastructure and local expertise<br />

allows us to expect the development of locally coordinated<br />

research addressing pertinent regional health questions benefıting<br />

the local community.<br />

What Are Some of the Challenges of Globalization of<br />

Clinical Trials?<br />

The globalization of clinical trials raises logistical challenges<br />

that need particular attention. In Table 1, we present a few<br />

general suggestions to address some of the issues and help in<br />

the conduct of global trials; only some of them are addressed<br />

in the discussion. As a fırst consideration, we need to take<br />

into account the wide cultural differences among regions<br />

participating in international clinical trials. Although this<br />

can be seen as a positive consequence that will certainly enrich<br />

the process making results more widely applicable, cultural<br />

characteristics remain a very particular aspect that<br />

needs to be addressed from the inception of the trial. The<br />

perception of what clinical research is varies substantially<br />

across regions and populations, and may influence the willingness<br />

of subjects to participate in a study. Interpretation of<br />

placebo arms, local dietary habits, use of herbal medications<br />

or alternative treatment methods, adherence to treatment<br />

and other protocol procedures, and reporting of adverse<br />

events all can be perceived differently in different regions of<br />

the world. The patient-doctor relationship also varies across<br />

cultures and may have an effect in different aspects of care<br />

that can affect the results of a clinical trial.<br />

One of the most central challenges of globalization relates<br />

to the regulatory aspect of running trials across borders with<br />

different legislations. Even though there are initiatives to harmonize<br />

regulatory legislation across regions and countries, it<br />

remains a very diffıcult objective to reach. Good clinical practice<br />

(GCP) harmonization has gone a long way and has been<br />

TABLE 1. Addressing Some of the Challenges of Globalization of Clinical Trials<br />

Problem<br />

Solution<br />

Regulatory Standards<br />

Harmonize regulatory standards, processes, and procedures for the pharmaceutical industry (e.g., ICH, ICH Global<br />

Cooperation Group Members)<br />

Share science-based goals and standards for product safety, quality, and efficacy<br />

Leveraging Knowledge and Resources<br />

Use finite resources strategically and more efficiently, sharing knowledge and information, leveraging inspection<br />

resources (share inspection data, plan joint inspections, provide parallel advice to sponsors, organize regular<br />

discussions that increase communication)<br />

Advancing Regulatory Science<br />

Actively engage global partners to harness scientific development, resources, and brainpower to support<br />

science-based regulatory decision making and pursue the best possible public health solutions<br />

Risk-Based Monitoring and Inspection<br />

Use innovative strategies and tools to identify sites for clinical inspection (e.g., GCP risk-based site selection<br />

tool for clinical inspection)<br />

Build Quality During the Planning<br />

Incorporate prevention strategies to avoid critical errors, and monitor for those errors<br />

Stages of Clinical Trials<br />

In the planning stages of the protocol, consider potential regional variations in standards of care and the<br />

impact they may have in trial results<br />

Central Laboratories and Bio-Banking<br />

Decentralize laboratories developing regional expertise that will have significant “carry-over” benefits once the<br />

trial is completed<br />

Advance, harmonize, and simplify bio-bank regulatory issues<br />

Invest in Research and Evidence-<br />

Characterize the epidemiology of disease in specific regions<br />

Based Cancer Care Relevant to<br />

Create and strengthen national cancer registries<br />

Each Region<br />

Monitor local cancer outcomes and study the regional cost-effectiveness of specific interventions<br />

Build a clinical trials infrastructure that is sustainable and will support local/regional innovative research and<br />

educational opportunities<br />

Promote translational research initiatives<br />
