Treatment Patterns and Medication Adherence Among Patients Diagnosed with Multiple Myeloma and Treated with Panobinostat

AIM: To examine real-world treatment patterns in multiple myeloma (MM) patients treated with panobinostat. MATERIALS & METHODS: Using a US claims database, MM patients treated with panobinostat during 02/01/2015-01/31/2017 were evaluated. Lines of therapy, combination regimens, dosing and duration were measured. RESULTS: Ninety-five patients were included (mean age: 61.4 years). Patients were heavily pretreated, with 88.4% exposed to both a proteasome inhibitor and an immunomodulatory agent. A panobinostat containing regimen was started in the fourth or more (86%) lines of therapy within a median of 3.77 years from initial treatment. The most common treatment combination was bortezomib/dexamethasone/panobinostat (31.6%) with 69.5% receiving the recommended dose (20 mg). Mean duration was 98.8 days. CONCLUSION: Patients received the recommended dose, most commonly with bortezomib and dexamethasone. Panobinostat was used in heavily pretreated patients within 4 years post-diagnosis, reflecting an advanced MM population.
