Specifically, this bill : 1)Permits a pharmacist to substitute a biosimilar for a prescribed biological product only if all of the following conditions are met: a) The product selected as a biosimilar has been approved by SB 598 Page 2 the federal Food and Drug Administration (FDA) and has been determined to be interchangeable with the prescribed biological product; b) The prescriber does not personally indicate, either orally or in his or her own handwriting, "Do not substitute," or words of similar meaning, as specified; and, c) For prescriptions filled prior to January 1, 2017, the pharmacy notifies the prescriber within five business days whether the prescription dispensed was a biological product or an interchangeable biosimilar, or enters the information in a patient record system shared by the prescriber. However, no notification is required if the prescriber indicates "Do not substitute," if there is no FDA-approved interchangeable biosimilar, or if a refill prescription is not changed from the product originally dispensed. 2)Prohibits a biosimilar substitution if the prescriber personally indicates "Do not substitute," as specified. 3)States that substitution is within the discretion of the pharmacist, unless the prescriber indicates otherwise. 4)States that the pharmacist who selects the biosimilar to be dispensed according to this bill shall assume the same responsibility for substituting the biosimilar as he or she would incur by filling a prescription for a biosimilar prescribed by name. 5)States that there shall be no liability on the prescriber for an act or omission by a pharmacist in selecting, preparing, or dispensing a biological product pursuant to this bill. 6)Prohibits the pharmacist from substituting a biosimilar unless the biosimilar costs the patient the same or less than the prescribed biological product, as specified. 7)States that the provisions of this bill shall apply to all prescriptions, including those presented by or on behalf of persons receiving assistance from the federal government or pursuant to the Medi-Cal Act. 8)Requires the substitution of a biosimilar to be communicated to SB 598 Page 3 the patient. 9)Requires the Board of Pharmacy (BOP) to maintain on its public Internet Web site a link to the current list, if available, of biosimilar products determined by the FDA to be interchangeable. 10)States that nothing in this bill prohibits the administration of immunizations, as specified. 11)States that nothing in this bill prohibits a disability insurer or health care service plan from requiring prior authorization or imposing other appropriate utilization controls in approving coverage for any biological product. 12)Defines the following: a) "Biological product," "biosimilar," and "interchangeable" have the same meanings that apply to those terms under the federal Public Health Service Act, as specified; b) "Prescription," with respect to a biological product, has the same meaning as used in the Federal Food, Drug, and Cosmetic Act, as specified; and, c) "351(k) pathway" refers to the licensure of a biological product as a biosimilar or an interchangeable biosimilar by the FDA pursuant to the federal Public Health Service Act, as specified. 13)States that no reimbursement is required by this act pursuant to Section 6 of Article XIIIB of the California Constitution because the only costs that may be incurred by a local agency or school district will be incurred because this act creates a new crime or infraction, eliminates a crime or infraction, or changes the penalty for a crime or infraction, within the meaning of Section 17556 of the Government Code, or changes the definition of a crime within the meaning of Section 6 of Article XIIIB of the California Constitution. FISCAL EFFECT : According to the Assembly Appropriations Committee, contingent on future federal FDA approval of biosimilars, biosimilar substitution could result in significant future savings in state health programs (primarily Medi-Cal, California Public Employees' Retirement System (CalPERS), and SB 598 Page 4 correctional health). Like generic versions of brand-name drugs, biosimilars are likely to be lower in cost than the prescribed biologics. Given that the FDA's approval process has not been finalized and no biosimilars are available, it is difficult to precisely estimate when and to what extent potential savings from biosimilar substitutions will accrue. Actual savings will depend on the biosimilar penetration rate and the cost difference between biosimilars and reference products. However, given plausible estimates of these variables, it is reasonable to assume cost savings to the state could eventually be in the tens of millions of dollars annually. COMMENTS : 1)Purpose of this bill . This bill will allow pharmacists to substitute FDA-approved interchangeable biosimilar pharmaceuticals for biological pharmaceuticals in the same way that pharmacists currently substitute generic drugs for name brand drugs. This bill will also require pharmacists to notify prescribers of the change until 2017. This bill is author-sponsored. 2)Understanding biologic and biosimilar drugs . A "biologic" drug is one that is created by biological rather than chemical processes. Biologics have been available for more than 20 years and include enzymes, human growth hormones, human insulins, interleukins, and vaccines. Many biologics are among the most costly medicines available, ranging from $1,000 to $50,000 per treatment. Biologic drugs represent a fast-growing segment of the pharmaceutical market, constituting 32% of products in the development pipeline and accounting for around 10% of pharmaceutical expenditures (as of 2011). The biologic market is expected to grow more than 20% per year. A "biosimilar" is a biologic drug that is designed to be comparable to a particular existing biologic drug, known as the biologic "reference" drug. Some manufacturers will seek "interchangeable" status for their biosimilar, a designation granted by the FDA that means those biosimilar drugs may be substituted for the biologic reference drug without any expected change in clinical outcomes. SB 598 Page 5 There are currently no biosimilars approved by the FDA for use in the United States, and FDA has not yet received any applications for a biosimilar. However, as of February 6, 2013, FDA's Center for Drug Evaluation and Research had received 50 requests for an initial meeting to discuss biosimilar development programs for 12 different reference products, held 37 initial meetings with sponsors, and received 14 Investigational New Drug applications for biosimilar development programs. It is anticipated that biosimilars will substantially reduce pharmaceutical costs once they are introduced. Industry studies and academic articles indicate a potential cost savings of 10-40% for a biosimilar compared to a biologic reference drug, which would potentially expand access to these important but expensive medications. This bill will require BOP to maintain on its Web site a link to the current list, if available, of biosimilar products determined by the FDA to be interchangeable. 3)Current law on generic substitutions . In practice, this bill would allow a pharmacist to substitute an interchangeable biosimilar for a prescribed biologic to save money, in the same way a pharmacist may currently substitute a generic for a brand name drug. Currently, a pharmacist filling a prescription order for a drug prescribed by its brand name may substitute a generic drug instead, unless the prescriber personally indicates verbally or in writing not to substitute. The prescriber is not liable for the pharmacist selecting, preparing, or dispensing a generic drug, and a pharmacist may not substitute a generic drug unless it results in cost savings for the patient. These existing provisions of law would apply to the substitution of interchangeable biosimilars as well, except that a biosimilar may be substituted which costs the patient the same or less than the prescribed biological product. 4)Prescriber notification . This bill would require a pharmacist to inform the prescriber of the interchangeable biosimilar substitution within five business days of the selection, until January 1, 2017. The pharmacist has the option of notifying the SB 598 Page 6 prescriber by entering the information in a patient record system shared by the prescriber. The three-year sunset on the notification provision was added in the Senate Business, Professions, and Economic Development Committee with the understanding that "accountability for biosimilars may be achieved when California's e-pedigree law, creating a track and trace system for drugs in this state, is implemented, or in the event that Congress creates a national track and trace system. Accountability may also be heightened through processes created by the FDA for biosimilars and through natural market channels once biosimilars are utilized more frequently." 5)Comparing biosimilars with generic drugs . According to the FDA, a generic drug is identical -- or bioequivalent -- to a brand name drug. However, a biosimilar is not, and cannot be, the exact bioequivalent of a biologic reference drug because of minor variations in the product caused by the high level of complexity involved in making it. According to the Biotechnology Industry Organization, "a drug is typically manufactured through chemical synthesis, which means that it is made by combining specific chemical ingredients in an ordered process." In contrast, "[a] biologic is manufactured in a living system such as a microorganism, or plant or animal cells. "The living systems used to produce biologics [and biosimilars] can be sensitive to very minor changes in the manufacturing process. Small process differences can significantly affect the nature of the finished biologic and, most importantly, the way it functions in the body. To ensure that a manufacturing process remains the same over time, biologics manufacturers must tightly control the source and nature of starting materials, and consistently employ hundreds of process controls that assure predictable manufacturing outcomes. "Process controls for biologics are established separately for each unique manufacturing process/product, and are not applicable to a manufacturing process/product created by another manufacturer. These process controls may also be confidential to the original manufacturer. Therefore, it would be difficult or impossible for a second manufacturer to make the 'same' biologic SB 598 Page 7 without intimate knowledge of and experience with the innovator's process." Because of these complexities, the FDA has established a new pathway to approve biosimilar drugs. 6)Biologics Price Competition and Innovation Act . The Biologics Price Competition and Innovation Act (Act) was enacted as part of the federal Affordable Care Act on March 23, 2010. The Act created an abbreviated licensure pathway for biosimilars. The Act defines "biosimilarity" to mean that "the biological product is highly similar to the reference product notwithstanding minor differences in clinically inactive components" and that "there are no clinically meaningful differences between the biological product in terms of the safety, purity, and potency of the product." FDA sets an even higher standard for biosimilar drugs that a manufacturer wants to deem "interchangeable" with a biologic reference drug. To attain interchangeability, according to the FDA, "a [manufacturer] must provide sufficient information to demonstrate biosimilarity, and also to demonstrate that the [interchangeable biosimilar] can be expected to produce the same clinical result as the reference product in any given patient and, if the [interchangeable biosimilar] product is administered more than once to an individual, the risk in terms of safety or diminished efficacy of alternating or switching between the use of the biological product and the reference product is not greater than the risk of using the reference product without such alteration or switch." In other words, a patient should not experience a difference between an interchangeable biosimilar and its reference biologic. The Act expressly states that a pharmacist or other dispenser may substitute an interchangeable biological product for the reference product without consulting the prescribing doctor.
