A biosimilar is a biologic product that is similar to a reference biopharmaceutical product, the manufacturing process of which hinders the ability to identically replicate the structure of the original product, and therefore, it cannot be described as an absolute equivalent of the original medication. The currently available technology does not allow for an accurate copy of complex molecules, but it does allow the replication of similar molecules with the same activity. As biosimilars are about to be introduced in oncology practice, these must be evaluated through evidence-based medicine. This manuscript is a position paper, where the Brazilian Society of Clinical Oncology (SBOC) aims to describe pertinent issues regarding the approval and use of biosimilars in oncology. As a working group on behalf of SBOC, we discuss aspects related to definition, labeling/nomenclature, extrapolation, interchangeability, switching, automatic substitution, clinical standards on safety and efficacy, and the potential impact on financial burden in healthcare. We take a stand in favor of the introduction of biosimilars, as they offer a viable, safe, and cost-effective alternative to the biopharmaceutical products currently used in cancer. We hope this document can provide valuable information to support therapeutic decisions that maximize the clinical benefit for the thousands of cancer patients in Brazil and can contribute to expedite the introduction of this new drug class in clinical practice. We expect the conveyed information to serve as a basis for further discussion in Latin America, this being the first position paper issued by a Latin American Oncology Society.

ABSTRACT The manufacturing process for biological products is complex, expensive and critical to the final product, with an impact on their efficacy and safety. They have been increasingly used to treat several diseases, and account for approximately 50% of the yearly budget for the Brazilian public health system. As the patents of biological products expire, several biosimilars are developed. However, there are concerns regarding their efficacy and safety; therefore, the regulatory agencies establish rules to approve and monitor these products. In Brazil, partnership programs between national government-owned companies and private technology holders have been implemented, aiming at knowledge sharing, capacity-building and technological transfer. Such partnerships locally promote manufacturing of these strategic drugs at reduced costs to the public health system. These agreements offer mutual advantages to both the government and patent holders: for the former, a biotechnological development flow is established and enables potential cost reduction and self-sufficient production; whereas for the latter, exclusive sales of the product are ensured during technological transfer, for a fixed period.

RESUMO O processo de manufatura de produtos biológicos é complexo, oneroso e crítico para o produto final, com impacto em sua eficácia e segurança. Seu uso está sendo cada vez mais ampliado no tratamento de diversas doenças, e cerca de 50% do orçamento anual do sistema de saúde público brasileiro é consumido por tais produtos. Com o término da proteção de patentes de produtos biológicos diversos, estão sendo desenvolvidos os biossimilares. Porém, há preocupações relacionadas com sua eficácia e segurança, fazendo com que os órgãos reguladores criem regulamentações para sua aprovação e monitoramento. No Brasil, estão sendo implantados programas de parceria entre laboratórios públicos nacionais e laboratórios detentores de tecnologia, objetivando a obtenção de conhecimento, capacitação profissional e transferência desta tecnologia. Tais parcerias visam à produção local destes medicamentos estratégicos a um custo reduzido para o Sistema Único de Saúde. Os acordos oferecem vantagens mútuas para o governo e o laboratório detentor da patente do produto biológico: ao primeiro, estabelece-se um fluxo de desenvolvimento biotecnológico, que possibilita potencial redução de custos e autossuficiência na produção, enquanto ao segundo garante-se a exclusividade da venda do produto durante a transferência da tecnologia por um prazo estabelecido.
