The standard of care in medicine is not a static rule but a dynamic concept that evolves with scientific discovery. Landmark clinical trials continuously challenge existing practices, and when a new therapy demonstrates superior efficacy or a significant advantage, it can redefine the standard of care. For PharmD students, understanding this process, as exemplified by the development of BCR-ABL inhibitors for CML, is essential for critically appraising new evidence and applying the most current treatments.
1. A new therapy is most likely to redefine the standard of care when a clinical trial demonstrates it is:
- Slightly more expensive than the current standard.
- Available in a different color tablet.
- Significantly more effective or safer than the current standard.
- Produced by a larger pharmaceutical company.
Answer: Significantly more effective or safer than the current standard.
2. The development of tyrosine kinase inhibitors (TKIs) redefined the standard of care for Chronic Myeloid Leukemia (CML) by targeting what specific molecular abnormality?

Answer: The BCR-ABL fusion protein
3. The ENESTnd and DASISION trials were landmark studies that redefined the first-line standard of care in CML by comparing second-generation TKIs to what drug?
- Imatinib
- Hydroxyurea
- Interferon-alfa
- Busulfan
Answer: Imatinib
4. A non-inferiority trial can be a “pathway to establishing new standards of care” if the new drug:
- Is slightly less effective but has a much better safety profile or is more convenient.
- Is significantly more effective than the active control.
- Is compared against a placebo.
- Fails to meet the non-inferiority margin.
Answer: Is slightly less effective but has a much better safety profile or is more convenient.
5. What is the primary role of clinical practice guidelines in defining the standard of care?
- To provide optional suggestions that have no basis in evidence.
- To synthesize current evidence and provide recommendations for clinical decision-making.
- To set the price for new medications.

Answer: Was the first highly effective oral targeted therapy for a disease previously managed with less effective treatments.
7. A “team debate” on which TKI is better for CML forces students to evaluate what?

- The price of the old standard of care increases.
Answer: Clinical practice guidelines are updated to reflect the new evidence.
16. The development of Direct Oral Anticoagulants (DOACs) challenged warfarin as the standard of care for atrial fibrillation primarily due to:

- Their higher rate of drug-food interactions.
- The lack of any reversal agents.
Answer: Their improved convenience (no routine INR monitoring) and safety profile for certain bleeding events.
