ABSTRACT
We compared patient-reported outcomes (PROs) with once-weekly carfilzomib 70 mg/m2 (Kd70 mg/m2) vs. twice-weekly carfilzomib 27 mg/m2 (Kd27 mg/m2) plus dexamethasone in relapsed or refractory multiple myeloma (RRMM). Patient-reported convenience/satisfaction collected at Cycle 2, Day 1 was compared between groups using logistic regression. European Organization for Research and Treatment of Cancer QOL Questionnaire (QLQ-C30), MM-module (QLQ-MY20), and EuroQoL-5 Dimensions-5 Levels (EQ-5D-5L) questionnaires were administered at baseline, then every other cycle. PROs were compared between groups using mixed models for repeated measures. Times from randomization to first deterioration (TTD) in scores were analyzed using Cox regression. PRO analyses included 469 patients. Once-weekly Kd70 mg/m2 patients reported greater convenience (odds ratio [OR], 4.98; p < 0.001) and satisfaction (OR, 2.41; p = 0.059) vs. twice-weekly Kd27 mg/m2. The mixed models for repeated measures demonstrated no clinically meaningful differences in scores between treatment arms. Clinically meaningful deterioration in QLQ-C30 Global Health Status/QOL rates were 34.2% (once-weekly Kd70 mg/m2) vs. 40.3% (twice-weekly Kd27 mg/m2). TTD was longer for once-weekly Kd70 mg/m2 vs. twice-weekly Kd27 mg/m2 for QLQ-C30 fatigue (HR, 0.79; p = 0.035), QLQ-MY20 disease symptoms (HR, 0.67; p = 0.008), EQ-5D-5L index score (HR, 0.58; p = 0.002), and EQ-5D-5L Visual Analog Scale (HR, 0.75, p = 0.031). Once-weekly Kd70 mg/m2 improved convenience/satisfaction, and reduced HRQOL deterioration vs. twice-weekly Kd27 mg/m2, supporting convenient, once-weekly Kd70 mg/m2 dosing in RRMM.

OBJECTIVE: To evaluate the impact of an extended-release, once-daily morphine sulfate formulation on depressive symptoms and neurocognition in patients with chronic nonmalignant pain. DESIGN: Prospective, open-label, one-group trial with a pretest-posttest design. SETTING: Outpatient pain management clinic. PATIENTS AND INTERVENTION: Chronic nonmalignant pain patients inadequately controlled with short-acting opioid analgesics and eligible for treatment with once-daily morphine sulfate were initiated on a dose at or near the morphine-equivalent dose of the short-acting regimen. OUTCOMES: The following assessments were made at baseline and 4 weeks after initiating intervention: pain intensity, pain unpleasantness, pain suffering, pain behaviors, Beck Depression Inventory, and cognitive function. RESULTS: Eighty-four patients provided usable data. Pain intensity, unpleasantness, and suffering scores were significantly reduced at follow-up (P = 0.001). The mean Beck Depression Inventory scores were significantly lower at follow-up (P = 0.001). Significant improvements were seen in scores at follow-up on the three validated neurocognitive tests: the digit span test, the digit symbol substitution test, and the paced auditory serial addition test (P = 0.001). CONCLUSIONS: Achieving adequate pain control with once-daily morphine was associated with a reduction in pain and improvements in depressive symptoms and cognitive functioning in the short term.
