Abstract: Monoclonal antibodies and cell therapies play an increasingly significant role in anticancer therapy, but small molecules remain an essential part of combination chemotherapy. Despite the publication of many studies on the extended stability of small molecule preparations, not all licensed medicinal products and stability-determining factors are covered. Submitted: 26 April 2024; Revised: 9 May…

Abstract: The US Food and Drug Administration (FDA) proposed eliminating the distinction between biosimilars and interchangeable biosimilars with the stated aim of aligning with European policy and enhance biosimilar uptake. However, this move is misguided as it would result in widespread generic-style automatic substitution at the pharmacy level; which is rare in Europe. Physician confidence…
