Despite these recent efforts, there is more to be done in this field, especially when one considers that even generics are still not fully accepted treatments. There are several levels of misunderstandings, if not myths, surrounding biosimilars. Most patients are confused mainly because many clinicians have an ambiguous attitude vis-à-vis biosimilars, as recently reported in Switzerland. One of the most critical ones is that reference compounds are not cast in stone, that their manufacturing processes tend to evolve over time. Some pharmacological activities, such as antibody-dependent cell-mediated cytotoxicity (ADCC), can drift over time, which can have serious clinical consequences, as recently reported by X Pivot. It has also been recently reported that the relevance of large phase III clinical trials to compare biosimilars to reference compounds is more than questionable.

In order to address this communication challenge, biosimilar companies, regulators and healthcare leaders should, with the support of independent scientific and medical societies, significantly invest in training all medical professionals, including nurses. The development of patient information/assistance programmes can also definitely help; partnering with patients organizations and regulators, organizing Patient Advisory Boards to ensure the clinical study is feasible and that informed consent forms provide accurate and useful information is helpful. Finally, providing economic incentives to patients to accept biosimilar prescriptions is probably an important success factor.

Above all, it is time to consider patients as ‘partners’, and no longer as ‘subjects’. All stakeholders, including patients, must now realize that biosimilar adoption is one of the manifestations of an evolving Social Contract, by which patients accept biosimilars, allowing for expensive and life-saving biologicals to reach a wider population.
