Brazil was in 2010 the first Latin American country in regulating biosimilars [2]. The approval and registration of biological medicines in Brazil are regulated by the National Health Surveillance Agency (Agência Nacional de Vigilância Sanitária, ANVISA) through the Resolution of the Collegiate Board of Directors (RDC) no. 055/2010, which specify the minimum requirements to submit an application for registration of new and follow-on (copies) biological products [3]. 

ANVISA uses the terms of: (a) new biological product, for a new biological entity not yet registered; and (b) biological product, referring to the copy or follow-on products containing an active substance already registered [3].

Biosimilars are those biological products registered through development by comparability, which is the regulatory pathway used by a biological product or medicinal product to obtain registration, in which the comparability exercise in terms of quality, efficacy and safety between the product developed to be comparable and the comparator biological product was used, according to the definition of ANVISA [4]. Biosimilars still nowadays go through a strict examination as well as in countries outside the US and EU.

According to the RDC 055/2010 for establishing the criteria for follow-on biological approval in Brazil, there are two regulatory pathways for non-originator biologicals: (1) comparability (biosimilar) – a stepwise approach; and (2) stand-alone (non-biosimilar), however, only the comparability pathway is for the approval of biosimilar product. Table 1 shows the Regulatory pathways for registration of biological products by ANVISA, previously, biological product approved under the comparability is termed as ‘follow-on biologicals’ [1].

The first biosimilar approved by ANVISA was Celltrion’s Remsima (infliximab) (CT-P13) in April 2015 [5]. To date, 43 follow-on biologicals/biosimilars (from five different classes) on 13 different innovator biologicals have been approved in Brazil by ANVISA.

ANVISA approved its first follow-on biological totally manufactured in Brazil in October 2015, Eurofarma’s Fiprima (filgrastim), and its first follow-on biological developed, manufactured and commercialized in Brazil in May 2019, Cristália’s Criscy (somatropin) [6].
