Drug recording practices ASBM Drug recording practices

ASBM - US Prescribers and Biosimilars Naming Prescribe biologics? Question “Do you prescribe biologic medicines in your practice?” ASBM - US Prescribers and Biosimilars Naming

ASBM - US Prescribers and Biosimilars Naming Others’ patients? Question “Do you commonly treat patients who you are aware are being prescribed biologic medicines by another health care provider?” ASBM - US Prescribers and Biosimilars Naming

Identify in patient record – Someone else’s patient Question “When you treat a patient receiving a biologic medicine prescribed by another health care provider, do you identify the medicine in the patient record?” (N=309, those who commonly treat patients being prescribed biologic medicines by another health care provider) ASBM - US Prescribers and Biosimilars Naming

Identify in patient record? Question “When you prescribe medicine, whether chemical or biologic, do you identify the medicine in the patient record?” ASBM - US Prescribers and Biosimilars Naming

How biologics are identified Question “When you identify a medicine for prescription or recording in a patient record, are you more likely to identify the medicine by brand name, non-proprietary / scientific name, or NDC number?” How does it vary? ASBM - US Prescribers and Biosimilars Naming

Identification for reporting AEs Question “Physicians play an important role in the identification and reporting unexpected or serious adverse events to FDA and manufacturers. In the context of identifying a biologic (or, if you don’t prescribe biologics, any other drug) for purposes of reporting an adverse event, would you prefer to identify the medicine by a product name or number (National Drug Code number)?” ASBM - US Prescribers and Biosimilars Naming

Recording changes in patient’s file Question “When a pharmacy contacts you regarding a change in the medicine a patient receives (for example, to request approval for a change due to insurance coverage), how often do you record that change in the patient's file?” ASBM - US Prescribers and Biosimilars Naming

Product Naming attitudes & beliefs ASBM Product Naming attitudes & beliefs

Structurally identical? Question “In the US, all medicines must have a non-proprietary scientific name upon approval. The manufacturer may choose to also designate a brand name for the product. If two medicines have the same non-proprietary scientific name, does this suggest to you or imply that: …the medicines are structurally identical?” ASBM - US Prescribers and Biosimilars Naming

Both produce same result? Question “In the US, all medicines must have a non-proprietary scientific name upon approval. The manufacturer may choose to also designate a brand name for the product. If two medicines have the same non-proprietary scientific name, does this suggest to you or imply that: …a patient could safely receive either product and expect the same result?” ASBM - US Prescribers and Biosimilars Naming

Switch with same result? Question “In the US, all medicines must have a non-proprietary scientific name upon approval. The manufacturer may choose to also designate a brand name for the product. If two medicines have the same non-proprietary scientific name, does this suggest to you or imply that: …a patient could be safely switched between the products during a course of treatment and expect the same result as treatment with only one of the products?” ASBM - US Prescribers and Biosimilars Naming

Biologic medicines are therapeutic proteins produced using living cells. A copy of an original biologic made by a different manufacturer is referred to as a biosimilar or follow-on biologic rather than a generic because it will be similar, not identical, to the product it copies. Biosimilars are also referred to as subsequent entry biologics (SEBs) in Canada. In short, biosimilars are “copies” of biologic medicines, whereas traditional “generic” medicines are generally based on chemical products. As a result of the new biosimilar pathway to approval, biosimilar medicines are now available in the US market. Biosimilars intro

Familiarity with biosimilars Question “How familiar are you with biosimilar medicines?” ASBM - US Prescribers and Biosimilars Naming

Awareness of biosimilars approval process Question “Originator medicines are approved by the US Food and Drug Administration based on an evaluation of clinical data that demonstrates a medicine is safe and effective for the specified indication and data must be provided for every indication. The approval pathway for biosimilars is different than for originator medicines. Are you aware a biosimilar medicine may be approved for several or all indications of the reference product on the basis of clinical trials in only one of those indications?” ASBM - US Prescribers and Biosimilars Naming

Acceptability of biosimilars approval process Question “How do you feel about the fact that a biosimilar medicine may be approved for several or all indications of the reference product on the basis of clinical trials in only one of those indications?” ASBM - US Prescribers and Biosimilars Naming

Should FDA require distinct names? Question “The FDA has proposed a new policy that would require every biologic – whether originator or biosimilar – to have a distinct non-proprietary scientific name. In your opinion, should the FDA require a distinct non-proprietary scientific name for every biologic product – whether originator or biosimilar – approved by them?” ASBM - US Prescribers and Biosimilars Naming

Representative or random suffix? Question “The FDA has proposed a policy that would require the use of a distinct non-proprietary scientific name for all products, whether originator or biosimilar. This is intended to aid the process of pharmacovigilance and accurate prescribing and dispensing of medicines. In March of 2015, the FDA approved the first biosimilar product for the U.S. market. The product currently carries the scientific name “filgrastim-sndz.” In the case of filgrastim-sndz, the suffix “sndz” is intended to identify Sandoz as the manufacturer of the product. More recently, the FDA has proposed a further change to the naming of biologic products. In the case of filgrastim-sndz, the name would become “filgrastim-bflm,” where the suffix carries no meaning and is not indicative of the product’s manufacturer. For future product approvals, which of the following would you prefer?” ASBM - US Prescribers and Biosimilars Naming

Why representative / random? See verbatim responses in attached MS Word file. ASBM - US Prescribers and Biosimilars Naming

ASBM - US Prescribers and Biosimilars Naming Suffix content Question “For purposes of accurately identifying the medicine, a representative suffix – for example, one that resembles the manufacturer name – is preferable.” “For purposes of accurately identifying the medicine, I prefer a suffix that is a random 4-digit string of characters.” ASBM - US Prescribers and Biosimilars Naming

Substitution attitudes & beliefs ASBM Substitution attitudes & beliefs

Importance of DAW authority Question “Every state gives the prescriber the authority to specify that a generic chemical drug may not be substituted without contacting the prescriber, for example by specifying “DO NOT SUBSTITUTE” or “DISPENSE AS WRITTEN”. How important is it to you to have the authority to designate a biologic medicine as "DISPENSE AS WRITTEN" or "DO NOT SUBSTITUTE"?” ASBM - US Prescribers and Biosimilars Naming

Importance of notification Question “Some states require the pharmacist to notify the prescribing physician if a product other than the one prescribed is dispensed at the pharmacy. How important is it to you to be notified by the pharmacist if your patient receives a biologic medicine other than the one you prescribed?” ASBM - US Prescribers and Biosimilars Naming

Importance of notification – with awareness Question “How important would it be for you to be notified by the pharmacist that your patient has received a biologic other than the one you prescribed if you were aware that the product could cause an unwanted immune response in some patients or that small differences between brands could have clinical implications for patients?” ASBM - US Prescribers and Biosimilars Naming

Preferred timeline for notification Question “At what point would you prefer to be notified of a change in the biologic medicine dispensed?” ASBM - US Prescribers and Biosimilars Naming

ASBM - US Prescribers and Biosimilars Naming Why not important? Question “Why is it not important to you to be notified of a change from the medicine you prescribed?” (N=11, those who rate 4 or lower on importance of notification) ASBM - US Prescribers and Biosimilars Naming

Preference for contact? Question “How do you prefer to be contacted by a pharmacy about prescription changes? Please select one.” ASBM - US Prescribers and Biosimilars Naming
