Treatment patterns and health care resource utilization among patients with relapsed/refractory systemic light chain amyloidosis

Abstract Background: Treatment for patients with systemic light chain (AL) amyloidosis remains challenging. Our study aims to describe treatment patterns for both newly diagnosed and relapsed/refractory AL (RRAL) amyloidosis, and to assess clinical outcomes, healthcare costs, and resource utilization during the first year following a diagnosis of RRAL amyloidsis. Methods: This was a retrospective observational study of adult patients with AL amyloidosis using the US Optum administrative claims data during 1/1/2008 to 6/30/2015. Diagnosis was based on both ICD-9 codes and treatments with a claim for AL-amyloidosis-specific anticancer systemic agents. Results: Of 334 patients with AL amyloidosis, 43.1% were considered as RRAL amyloidosis. The majority (75%) of RRAL amyloidosis patients had organ involvement prior to the second line treatment. Proteasome-inhibitor-based regimens were most frequently used (41.0% for first-line AL, 30.6% for RRAL amyloidosis). Organ deterioration and mortality rates were 49.3% and 10.4%, respectively, during the two years following relapse. The average monthly cost was

Prevalence and Predictors of Treatment Among Newly Diagnosed Symptomatic Multiple Myeloma (NDMM) Medicare Beneficiaries in the U.S.

OBJECTIVES One-third of patients with multiple myeloma (MM) are diagnosed at age≥75years. Older patients have increased incidence of cardiovascular disease (CVD) and renal insufficiency (RI), hallmark complications of MM. We examined cumulative incidence of CVD and RI in relapsed/refractory MM (RRMM) and outcomes by age and RI/CVD. MATERIALS AND METHODS Retrospective cohort study using a large US electronic medical records database of adult patients with RRMM initiating first- and second-line therapy (2LT) between 1/2008-06/2015. RI and CVD comorbidities were based on diagnosis codes and/or lab values. RESULTS Among 628 patients, 37.1% were ≥75years. Cumulative incidence of CVD and/or RI increased from 47.7% at MM diagnosis to 67.8% at first relapse. Age≥75years had a trend toward higher risk of relapse post 2LT, proxied by time to next treatment (TTNT), (adjusted HR: 1.28; 95% CI: 1.00, 1.65; P=0.05). TTNT was significantly higher with comorbid CVD+RI (adjusted HR: 1.50; 95% CI: 1.11, 2.02; P<0.01). Age≥75years, RI, CVD, and CVD+RI were associated with increased mortality risk from 2LT initiation; adjusted HR: 1.66 (95% CI: 1.19, 2.33; P<0.01), 1.51 (95% CI: 1.01, 2.26; P=0.04), 1.75 (95% CI: 1.03, 2.96; P=0.04), and 1.95 (95% CI: 1.29, 2.93; P<0.01), respectively. CONCLUSION Despite treatment with novel agents for RRMM in 86% of patients, an outcome gap persists for older patients and those with RI and/or CVD. Personalized treatment approaches that account for age and comorbidities, and further evaluation of innovative regimens and dosing schedules, are needed to improve outcomes for these patients.
