1. For questions 1-6, please use the following Patient CASE:
AG is a 43-year-old female with newly diagnosed triple-negative breast cancer (TNBC) (i.e., estrogen receptor [ER]-, progesterone receptor [PR]-, and human epidermal growth factor receptor 2 [HER2]- negative) with metastases to the skin and bones. She presents to clinic for consideration of systemic therapy for the treatment of her cancer, and she asks about immunotherapy.

In order for AG to be considered for an immune checkpoint inhibitor (ICI) combination therapeutic regimen for the treatment of her breast cancer, what marker/alteration must her tumor express?

2. What FDA-approved companion diagnostic should be used to evaluate AG's tumor to assess her eligibility for atezolizumab?

3. As the pharmacist, you order the appropriate companion diagnostic for ICI therapy for AG and the result was positive. What ICI combination is FDA-approved for the first-line treatment of AG's cancer?

4. AG was treated with 3 cycles of ICI plus chemotherapy when she developed severe colitis (grade 3: 7 bowel movements per day above her “normal”) that was deemed to be an immune-mediated adverse event (imAE). What is the appropriate action regarding her ICI?

5. What measures should be initiated for AG to treat and manage her immune-mediated colitis?

6. AG returned to clinic after 2 weeks on systemic corticosteroids. Her symptoms persisted, so her corticosteroid dose was increased. After another 2 weeks, she is seen back in clinic and reports only 3 stools per day above her baseline (grade 1). What is the appropriate action at this time?

7. For questions 7-10, please use the following CASE:
MA is a 49-year-old premenopausal Caucasian woman who presents to the outpatient oncology clinic for her newly diagnosed breast cancer found through screening mammogram. She had undergone an ultrasound, which confirmed a mass of 1.3 cm x 2.0 cm and negative axillary lymph nodes. A core biopsy of the mass indicated an invasive ductal carcinoma with nuclear grade of 3 and a Ki-67 of 58%; the tumor was estrogen and progesterone receptor negative, and the human epidermal growth factor receptor 2 (HER2) immunohistochemistry (IHC) score was +1. Her other work up showed no metastatic disease. The disease at this time is considered stage II (T2, N0, M0) triple-negative breast cancer (TNBC).

Which of the following choices would not be appropriate therapy for MA at this point?

8. MA is interested in neoadjuvant therapy with an immunotherapy agent. Which of the following is the most accurate information to provide to the patient?

9. MA would like to know, in detail, her chances of achieving pathologic complete response (pCR) if she receives standard neoadjuvant chemotherapy alone. What do you advise her?

10. Upon further testing, MA's tumor is noted to have BRCA1 and BRCA2 mutations and is programmed death-ligand 1 (PD-L1) positive. Which of the following is true, according to the IMpassion130 study?
