          SUMMARY  :  Permits a pharmacist to substitute a biological  
         pharmaceutical with a "biosimilar" pharmaceutical in the same  
         manner as generic drugs are substituted, and for prescriptions  
         filled prior to January 1, 2017, requires the pharmacist to notify  
         the prescriber.  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
