Real-World Data on Frontline (FL) Treatments in Multiple Myeloma (MM) Patients across EU5 Countries

Objective

This analysis was conducted to understand the clinical practice on FL treatment in patients with MM across EU5 countries.

Methods

Real world data were collected through Adelphi's Disease-Specific Programme^TM - a point in time survey administered to physicians (n=241) in EU5 countries between Nov 2017 - Feb 2018. Stem Cell Transplant eligibility and treatments, including number of cycles and dosage, were collected from patient record forms (n=1952). Summary statistics were reported and analysed descriptively.

Results

Data on FL treatment was collected for 1952 patients; 988 (51%) were still on FL treatment at the time of data collection.

Bortezomib-based regimens were used in more than 70% of patients - in both transplanted/transplant eligible (TE, n=572) and non-transplanted/transplant ineligible patients (TIE, n= 1380).

In TIE patients, bortezomib, melphalan and dexamethasone (VMP) was the most commonly used regimen, covering almost one third of the patients (31%), followed by bortezomib, either in combination with cyclophosphamide and dexamethasone (VCD, 10%) or thalidomide and dexamethasone (VTD, 10%). The other two FL regimens currently approved in Europe - thalidomide, melphalan and dexamethasone (MPT) and lenalidomide and dexamethasone (Rd) have patient shares of 9% each. When analyzing the TIE patients undergoing FL treatment at time of data collection (n=606), VMP remained the most used regimen (29%) and Rd the second (15%), with VTD and MPT being used in 8% of patients.

In TE patients, VTD was the most commonly used induction regimen, being used in 50% of patients, followed by VCD (21%). The numbers remained the same when analyzing the TE patients in FL treatment at time of data collection (n=382), with 54% and 22% using VTD and VCD, respectively.

Conclusions

Collectively these results indicate that bortezomib-based regimens remain the standard of care in FL treatment of MM in EU5, in both transplant and non-transplant settings.
