Biosimilars are manufactured with the goal of closely mirroring the composition and treatment profile of an innovator biologic product, but are produced without access to the innovator’s proprietary manufacturing processes.
Two biologics made using different cell lines and manufacturing processes will rarely, if ever, be exactly the same, hence the name “biosimilar.” Simply put, biosimilars are not generics, and those suggesting otherwise are incorrect. Thus, current state laws governing the substitution of generics are not, and should not be, automatically applicable to biosimilars.Patients and physicians managing chronic conditions are generally aware of which treatments work best in their unique circumstances. Therefore, the decision to change to a biosimilar treatment is best made by doctor and patient. However, at a minimum, providing notice to the prescribing doctor and patient ensures everyone in the treatment continuum is informed of decisions to switch to a different biologic drug, either at the pharmacy level or due to insurance coverage guideline
Until recently, there was no pathway for the development and approval of biosimilar products in the United States. The US Food and Drug Administration is currently developing such a pathway. Even after it is enacted, the policy on whether one biologic product may be substituted by dispensers when a different biologic product was prescribed will continue to be governed by state law.
At present, most state laws need to be updated to address the commercialization and distribution of new biologic products and their biosimilar competitors, which are set to enter the marketplace over the next few years. Sound policy in each state outlining the parameters for safe substitution of interchangeable biologics is the best option to ensure patients have access to the most effective and appropriate treatments possible.
Recognizing the authority US states have over biosimilar and interchangeable biologic medicines, Biotechnology Industry Organization (BIO) developed five principles on biologic substitution that we believe should be considered by all states when evaluating biosimilar legislation. Briefly stated, these principals are:
These principles strike the appropriate balance of preserving the physician-patient relationship, protecting patients, and promoting a competitive market for biologic therapies. We welcome the opportunity to further discuss this issue with lawmakers as they seek to address vital drug safety measures that accompany this cutting-edge technology.
