Page 1 This activity was recorded on March 29, 2017 during the HOPA Annual Meeting. On September 28, 2017, the National Comprehensive Cancer Network updated its NSCLC Clinical Practice Guidelines to include the use of osimertinib as a 1 st line treatment option for patients with locallyadvanced or metastatic EGFR mutationpositive NSCLC. Subsequently, on October 9, 2017, the FDA granted Breakthrough Therapy Designation for osimertinib in the 1 st line treatment of patients with EGFRpositive NSCLC.

NCCN Guidelines Version 4.2017

Adapted from: https://www.nccn.org/professionals/physician_gls/pdf/nscl.pdf. 

*Beware of flare phenomenon in subset of patients who discontinue    EGFR TKI. If disease flare occurs, restart EGFR TKI. 

**If tissue biopsy is not feasible, plasma biopsy should be considered.    Consider reflex to tissue‐based testing, if plasma test is negative for   the T790M mutation.

Patient DD: Treatment Course

What if the T790M by ctDNA was negative?

A. Continue erlotinib at the current dose

B. Consider tissue biopsy to confirm absence of T790M mutation

C. Initiate osimertinib regardless of T790M status

D. Plan for outpatient chemotherapy after discharge from hospital

• 1/17/2017: patient initiated Osimertinib 80 mg PO once daily

• Patient counseling:

– Most common side effects: diarrhea, rash, nail changes, dry skin

– Can be taken with or without food

– Medication is restricted to a specialty pharmacy, patient and family must increase vigilance with regard to ongoing refills

– Follow‐up with thoracic medical oncology
