RESUMO
INTRODUCTION: Ciltacabtagene autoleucel (cilta-cel), a novel chimeric antigen receptor T (CAR-T) cell therapy, has demonstrated early, deep, and durable clinical responses in heavily pretreated patients with relapsed/refractory multiple myeloma (RRMM), and improvements in health-related quality of life (HRQoL) in CARTITUDE-1 (NCT03548207). Patient perspectives on treatment provide context to efficacy outcomes and are an important aspect of therapeutic evaluation. METHODS: Qualitative interviews were conducted in a subset of CARTITUDE-1 patients (n = 36) at screening, Day 100, and Day 184 post cilta-cel on living with MM, therapy expectations, and treatment experiences during the study. RESULTS: Patients most wanted to see change in symptoms with the greatest impact on HRQoL: pain (85.2%) and fatigue (74.1%). The primary treatment expectation was achieving remission (40.7%), followed by extended life expectancy (14.8%). Patients most often defined meaningful change as improvement in symptoms (70.4%) and return to normalcy (40.7%). The percentage of patients reporting symptoms (pain, fatigue, bone fracture, gastrointestinal, neuropathy, and weakness) decreased from 85.2% to 22.2% across symptom types at baseline to 29.2% to 0% on Day 184 after cilta-cel. Improved symptoms and positive sentiments corresponded with improved perception of overall health status and reduced pain level, respectively. Most patients reported that their expectations of cilta-cel treatment had been met (70.8%) or exceeded (20.8%) at Day 184, and 70.8% of patients considered cilta-cel therapy better than their previous treatments. CONCLUSION: Overall HRQoL improvements and qualitative interviews showed cilta-cel met patient expectations of treatment and suggest the long treatment-free period also contributed to positive sentiments.
