Managed care and hospital decision-makers should consider that biological drugs are different from traditional drugs in terms of their complexity and there is potential for problems to arise when manufacturing is not strictly controlled. Furthermore, biological medicines are more difficult to characterize, produce, and reproduce than most traditional pharmaceuticals. This, in turn, can affect the medicine’s quality, safety, or efficacy, and can ultimately impact the reliability of supply, according to a presentation at the Hematology/Oncology Pharmacy Association’s annual conference in Los Angeles, in March.
