In today’s competitive landscape speed is key in getting a drug from discovery through to market. Everything that speeds up the clinical trials process (without sacrificing safety and quality) is a priority to today’s drug developers because it is essential in shortening a product’s time to market. Clinical trials across multiple regions of the world have become common practice, with the goal of bringing new drugs and devices to patients around the world, as fast as scientifically possible.
Conducting clinical trials in Latin America provides sponsors large patient populations within a condensed geographical area. For example, more than 626 million people live in Latin America, with 70% of the population concentrated in urban areas like Buenos Aires, Mexico City, Sao Paulo and Rio de Janeiro. Additionally, the commercial markets are attractive due to relatively lower cost for greater speed.
Latin America offers patients in medical centers with competent and qualified investigators and established regulatory systems at comparable cost. There are challenges, however, that require forward thinking and strategic planning to optimize timely study start and execution.
Selecting an Outsourcing Partner
One of the most important decisions a sponsor makes is choosing the right outsourcing partner to execute a successful clinical trial program in Latin America. Clinical trials conducted by a Contract Research Organization (CRO) may be completed more quickly than those conducted in-house by pharmaceutical companies, and there are some very compelling reasons for that.
A CRO with representation within the country will possess the expertise to navigate the waters of regulatory submission requirements within each given country, and lack of regulatory harmonization makes it challenging for the novice. Approval times vary widely and omission of required documents will delay review.
Furthermore, challenges to be expected and managed include status of Intellectual Property protection from country to country, cultural and medical differences, logistical challenges around drug storage depots, patient biologic sample handling, regulatory challenges associate with adaptive trail design, ethic review process and more. Site feasibility alone must consider public perception and work to dispel misconceptions in multinational trials and identify and train sites of excellence, both in the private sector and in large metropolitan facilities.
An outsourcing partner must understand issues that affect the conduct of clinical trials unique to each country within Latin America, and be versed at accessing patients. They must have a representative that is a source of local culture, to provide insight to accommodate the diversity that exists within a given region in a country, and to address the challenges and concerns that arise.
Translation and Language Barriers
In addition to outsourcing the study execution, there is a translation component—working with a language services company who not only specializes in local languages and regional variations, but also translation of clinical research and regulatory documents. Only in some countries, the investigator´s brochure and a few other documents can be submitted in English, but these are rare exceptions. It is important to note that even though Spanish is spoken in most countries, except for Brazil, the meaning of certain words and phrases varies between countries.
Addressing language barriers therefore requires an understanding of the patient demographics in each country. Although all regulatory documents must be provided the official and written language of the country, any patient-related materials must be adapted for the target patient population. For example, the people of Peru predominantly speak three different languages: Spanish, Quechua and Aymara. In Colombia there are about 65 indigenous languages and nearly 300 dialects. Colombian Spanish is a mixture of the Caribbean dialect and Peruvian coastal dialect.
Dominant indigenous populations not only influence the way the language is spoken in each of these countries, but they are also responsible for differences in the local culture. Among the most common reasons for delays by ethics committees are problems with informed consent, and these are often associated with poor quality translation. In large part, this can be avoided if linguistic and cultural differences are properly addressed. Experts who are native speakers and have a background in clinical research are best equipped to perform such culturally sensitive translations.
