RESUMEN
Biopharmaceuticals make up a significant proportion of medicinal products used for the treatment of diseases such as cancer, arthritis, cardiac dysfunctions and AIDS. Access to therapies based on the use of these products has been limited as a result of the high marketing costs. Cuba has a biopharmaceutical industry with great potential for innovation, capable of developing new products and to produce others, like the biosimilars destined to fulfill the needs of its National Health System. The Center for State Control on the Quality of Drugs (CECMED) the Cuban NRA, is facing the challenge of regulating the approval of biosimilar products manufactured locally. Consequently, CECMED has issued a position paper establishing the basic principles for regulation of these products and a specific guideline on this was elaborated.
