Abstract: Abstract Introduction Capturing the patient experience during treatment is important to both regulatory authorities and to patients starting treatment. We identified the symptoms and side effects experienced by patients with advanced non-small-cell lung cancer during osimertinib treatment, to understand treatment expectations, satisfaction, and the level of difficulty coping with the side effects experienced during treatment. Methods Qualitative interviews (approximately 4–6 weeks after treatment initiation and again after approximately 4 months of treatment) were conducted during the phase I/II AURA clinical trial of osimertinib, a tyrosine kinase inhibitor of epidermal growth factor receptor-sensitizing and T790M resistance mutations. Results During the first interview (23 patients), the most commonly reported symptoms/side effects were coughing, itching, tiredness (each reported by 56.5% of patients), and rash (43.5%). During the second interview (21 patients), compared with the first interview, shortness of breath and diarrhea were reported by more patients (57.1 and 38.1%, respectively; both increased from 34.8%); tiredness remained predominant (42.9%); and itching (38.1%), coughing (38.1%), and rash (14.3%) were reported by fewer patients. At both interviews, the most frequently reported symptoms/side effects were also those most often rated by patients for bothersomeness and severity, and generally received mean scores in the low-to-moderate range. However, several rarely expressed symptoms/side effects (e.g., abdominal pain, frequent day time urination) received high bothersomeness ratings. At the second interview, patients were highly satisfied with osimertinib and had a low level of difficulty in coping with side effects during treatment. Conclusions These data enhance our understanding of patients’ experiences of symptoms/side effects, which could increase the accuracy of the osimertinib benefit–risk assessment, guide management of adverse events, and improve the information given to patients receiving the drug.
