Rituximab biosimilars in hematologic malignancies: the need for a real-world approach.

The introduction of rituximab biosimilars into healthcare systems can potentially help to control healthcare costs for the treatment of hematologic malignancies. However, there are currently several barriers to the uptake of biosimilars. This review discusses barriers to the adoption of rituximab biosimilars by stakeholders including patients and healthcare providers. We outline the importance of utilizing real-world evidence in providing additional clinical experience on rituximab biosimilars in hematologic malignancies to improve stakeholder confidence regarding their efficacy and safety. We conclude by offering recommendations for designing and conducting effective real-world studies. Such studies can provide evidence to help achieve lower-priced biologics and improved patient access to help sustain the treatment of hematologic malignancies with biologics, including rituximab biosimilars.
