In a white paper, Mohammed Omair and colleagues describe the 2nd symposium on biosimilar and originator biologicals that was held in Riyadh, Saudi Arabia in January 2020 [2]. This success of the 1st symposium held in September 2018 encouraged the scientific committee to proceed with the organization of the 2nd event, adding workshops and increasing interactive sessions. This educational activity aims to gather different stakeholders in one place in order to discuss the many different aspects of biosimilars. The lectures, workshops and debates were attended by more than 200 participants over two and a half days. The scientific agenda included four main tracks:

1. Introduction to biosimilars: This track discussed the biotechnology of biosimilar manufacturing and how it differs from originators with an emphasis on the concept of ‘totality of evidence’, which was also explained.
2. Clinical practice management: This track included a variety of specialists that discussed the clinical challenges and benefits of introducing biosimilars.
3. Regulatory and pharmacoeconomics: This track highlighted the regulatory requirements of biosimilar approval in Saudi Arabia and internationally. In addition, the basics of pharmacoeconomic studies that should be learned were introduced.
4. Pharmacovigilance: This track covered how international databases are tracking the safety aspects of biosimilars and introduced to attendees the national Saudi pharmacovigilance database and how to report cases.

Many important unmet needs were raised by both speakers and delegates. The most essential were found to be:

• to conduct local real-world studies to gather evidence on biosimilars in naïve and switched patients, with the aim of developing clinical practice guidelines
• continuous collaboration between involved societies and official bodies to adapt the most suitable strategy and monitor its clinical and economic impact.

The authors concluded that ‘despite’ the ‘many challenges and ambiguities, the introduction of biosimilars into the Saudi Healthcare system will hopefully lead to substantial cost-savings’. They added that it is also important to organize and report on educational activities related to this topic.
