Patient Characteristics and Outcomes of Relapsed/Refractory Multiple Myeloma in Patients Treated with Proteasome Inhibitors in Germany.

ABSTRACT:

Introduction

Real-world data reflects treatments and outcomes in clinical practice in contrast with controlled clinical trials. This study evaluates real-life multiple myeloma (MM) patients receiving proteasome inhibitor (PI)-based treatments in the second or third therapy line in 2017 in Germany.

Methods

This is a retrospective chart review on adult relapsed/refractory MM patients treated with ?1 dose of a PI-based regimen in either the second or the third line of therapy. Participating physicians had ?3 years of clinical experience in treating symptomatic MM patients and used PI according to the label.

Results

Distinct patient profiles for each PI-based regimen emerged. Younger, fitter, transplant-eligible patients received novel PI triplets such as carfilzomib in combination with lenalidomide and dexamethasone (KRd) or IRd. Patients receiving lenalidomide in first-line therapy mostly received lenalidomide-free regimens in second-line therapy. In high-risk patients, no clear treatment patterns could be ascertained. The complete response rates were highest with KRd (13.0%), followed by carfilzomib in combination with dexamethasone (Kd) (5.7%) and bortezomib (4.8%). The very good partial response rates were highest with IRd (76.9%), followed by KRd (53.7%), Kd (25.7%), and bortezomib (20.5%). None of the KRd- or IRd-treated patients responded below a partial response.

Discussion/conclusion

Clear patient profiles for each PI type were observed. In second-line therapy, younger, fitter, transplant-eligible patients received novel-PI-based triplets, e.g., KRd or IRd. Patients treated with lenalidomide in first-line therapy mostly received lenalidomide-sparing regimens in second-line therapy. In high-risk patients no clear treatment patterns could be ascertained due to the limited sample size.

Project description:IntroductionMultiple myeloma remains an incurable plasma cell malignancy which, despite improvements in overall survival over the last decade, is characterized by recurrent relapse and is associated with a poor prognosis. This study investigates the use of novel agents in current real-world clinical practice in the management of relapsed and/or refractory multiple myeloma (RRMM) in Germany over different lines of therapy.MethodsA retrospective chart review was conducted for patients with RRMM treated at multiple centers across Germany between May 2017 and June 2018. Variables included patient demographics and clinical characteristics, current and prior treatment regimens, treatment response, cytogenetic abnormalities, testing methodology, and resource utilization.ResultsData were analyzed from 484 patients from 47 centers across Germany (60% male; average age over 70 years; majority at International Staging System stage 2 or 3). Bone pain and anemia were the most common symptoms at diagnosis, with 63% of patients receiving osteoprotective drugs. Approximately one-third (32%) of patients had received autologous stem cell transplantation and approximately 70% underwent cytogenetic testing. After failure to respond to first-line treatment, most patients received regimens containing second-generation proteasome inhibitors and monoclonal antibodies, with overall response rates greater than 90% in second line (95% and 90% for daratumumab-based and carfilzomib-based therapies, respectively). The incidence of unplanned hospitalization ranged from 11% to 16% across all treatment lines, with longer hospital stays required for treatment administration than for treatment-related toxicity.ConclusionAlthough treatment patterns for RRMM in Germany differ by line of therapy and are adapted as disease progresses, patients mostly receive combination regimens with carfilzomib or daratumumab in second and third lines, with high overall response rates achieved in all lines.
