Pharmacist Questions:
1. Which of the following is true?
- Major diseases treatable by biologics are less prevalent
- Biologics for major disease states are less expensive per prescription than those for small molecules
- Asthma is the most common condition treated with biologics
- Major diseases treatable by small molecules are less prevalent
2. Which is true about specialty drugs?
- They represent 10% of all US prescriptions
- By the year 2020, they are predicted to account for less than 73% of all medication spending
- They make up 1/3 of prescription drug spending in the US
- They were responsible for 50% of overall prescription spending growth over the last 5 year
3. Which is true regarding the cost of biosimilars?
- The processes for production are well-known and developed and therefore manufacturing costs are low
- The introduction of multiple biosimilars for one biologic is crucial to cutting costs
- The United States can expect price reductions of upwards of 50% when biosimilars are introduced
- There is a substantial price difference between innovator biologics and their biosimilar counterparts
4. Which of the biosimilar drugs currently in development might be expected to be the least expensive?
- Cetuximab
- Trastuzumab
- Filgrastim
- Pegfilgrastim
5. One of your patients is picking up a new prescription for infliximab-dyyb (Inflectra) for treatment of Chron’s Disease. They were previously on infliximab (Remicade) and have not had a flare-up in quite some time. What can you tell them to ease their hesitation to switch?
- Inflectra is an interchangeable biological product, so has been shown to produce the same clinical result as Remicade.
- Clinical data shows that Inflectra is “highly similar” to Remicade and your prescriber feels that you will continue to benefit from this less-expensive option.
- The makers of Inflectra had to show there was no danger in switching to-and-from Remicade in order to be approved.
- Talk to your doctor, I have no idea if they will work the same.
6. Which of the following can be used to describe a biologic drug?
- Low molecular weight
- Highly stable final product
- Complex three-dimensional structure
- Small chemical structures
7. Which drug may be prevented from automatic generic substitution in selected states?
- Lorazepam
- Lansoprazole
- Lisinopril
- Lamotrigine
8. Which is correctly paired?
- Biologics Price Competition and Innovation Act of 2009 & approval of biosimilar and interchangeable biological products
- FDA “Orange Book” & AB-rated interchangeable biological products
- Drug Price Competition and Patient Term Restoration Act of 1984 & approval of biosimilar and interchangeable biological products
- “Purple Book” & AB-rated interchangeable biological products currently in development
9. Interchangeable biologic products are which of the following:
- Structurally identical to an FDA-approved reference product
- Expected to produce the same clinical result as the reference product
- Required to cost the same as the reference product
- Associated with decreased risks compared to the reference product
10. A patient asks why her adalimumab (Humira) for psoriasis costs so much more than the generic cream she was prescribed previously. Which is the best explanation?
- Biologic drugs are more in-demand and therefore drug companies charge more
- Manufacturers of biologic drugs are held to higher purity standards
- Biologic drugs are more difficult to produce and store
- Drug manufacturers want to encourage the use of topical drugs first
11. Which is true of orphan drugs?
- Research and development spending is low due to low prevalence of orphan diseases
- Drug costs are kept low by the Orphan Drug Act of 1984
- Biologic drugs are too expensive to be developed as orphan drugs
- Manufacturers have smaller sample size requirements
12. Why can’t exact copies be made for biologic drugs?
- The law does not allow it
- The molecules are too small to replicate
- Growth conditions and cell lines are unique and proprietary information difficult to duplicate
- Harvesting, isolating, and purifying the cell lines is too costly
13. A patient approaches you with concerns about the cost of her adalimumab (Humira) treatment for rheumatoid arthritis. She heard about a “generic” version and would like to switch. What actions should you take?
- Interchange the patient to adalimumab-atto (Amievita)
- Interchange the patient to adalimumab-adbm (Cyltezo)
- Call the prescriber to initiate a change to a biosimilar medication
- Apologize to the patient for the misinformation and explain that paying for her current treatment is the only option
14. What is needed for a generic small molecule drug to gain “AB”-rating over “A”-rating?
- Demonstration of significant cost savings to the patient
- Evidence of a smaller side effect profile than the innovator drug
- No evidence of liver/kidney impairment in clinical trials
- In vivo or in vitro evidence of bioequivalence in clinical trials
15. Which is true about manufacturing of biologics?
- Many biologics are monoclonal antibodies, enzymes or hormones
- Variability in cells cultivated ensures drugs will be effective
- Weaker cell lines are chosen in order to ensure the resulting drugs will not be toxic
- Controlled environments are used to kill the cells for isolation and purification
16. What is a good counseling point for all patients on biologics?
- Biologics can be returned to the refrigerator without harm if exposed for less than 15 minutes to controlled room temperature
- Never leave your biologic in the car unless it is packed in a cooler
- Airport security will never allow biologic medications on a plane, so always plan to travel by car
- Package inserts do not address storage information, and the manufacturer must be called with all questions
17. A patient who is apprehensive about switching to a biosimilar from an innovator product can be counseled that:
- The biosimilar is always made by the same company as the reference product
- Clinical trials show that the safety, purity, and potency are the same for the approved condition for which it is interchangeable
- The structure of the biosimilar is identical to that of the reference product
- Honestly, the risks of switching are not assessed for approval and the patient is risking therapy failure
18. Which is true of biologic medications?
- They show efficacy in previously refractory patients
- They have a slower onset of benefit due to their small size
- They have a larger side effect profile due to complex mechanisms of action
- Treatment specificity opens up the size of the market that can be targeted
19. What is the most common indication for currently FDA-approved biosimilar medications?
- Cancers
- Neutropenia
- Inflammation
- Anemia
20. How are biosimilars and interchangeable biological products expected to affect the US in years to come?
- More medication errors will occur due to automatic interchange
- The healthcare system will save billions of dollars
- Increased overall costs to drug manufacturers will make it harder to produce small molecule generics
- Pharmacists will be allowed to prescribe biologic medications
