Background: Despite recent advances in therapeutic options, there remains an unmet need for treating patients with relapsed or refractory multiple myeloma, especially in those previously exposed or refractory to lenalidomide. This updated efficacy and safety analysis from the phase 3 CANDOR study compared carfilzomib, daratumumab, and dexamethasone (KdD) with carfilzomib and dexamethasone (Kd) in patients with relapsed or refractory multiple myeloma. Methods: In this updated analysis of the randomised, multicentre, open-label, phase 3 CANDOR study, patients (aged ≥18 years) with relapsed or refractory multiple myeloma, at least a partial response to between one and three previous therapies, and Eastern Cooperative Oncology Group performance status of 0–2, were recruited from 102 medical centres globally and randomly assigned (2:1) by interactive voice or web response software to receive KdD or Kd. Participants were stratified by disease stage, previous proteasome inhibitor or anti-CD38 antibody exposure, and number of previous therapies. All patients received intravenous infusions of carfilzomib twice per week at 56 mg/m2 (20 mg/m2 on days 1 and 2 during cycle 1) on days 1, 2, 8, 9, 15, and 16 of each 28-day cycle. Daratumumab (8 mg/kg) was administered intravenously on days 1 and 2 of cycle 1 and at 16 mg/kg weekly for the remaining doses of the first two cycles, then every 2 weeks for four cycles (cycles 3–6), and every 4 weeks thereafter. Patients received 40 mg dexamethasone weekly (20 mg for patients >75 years old). This analysis was a preplanned interim analysis for overall survival; however, at the time of data cutoff, overall survival data were not mature. The primary endpoint was progression-free survival. Here, we provide updated progression-free survival data, assessed centrally by Onyx Response Computer Algorithm in the intention-to-treat population, with 11 months additional follow-up. Adverse events were assessed in the safety population, which included all participants who received at least one dose of trial treatment. CANDOR is registered with ClinicalTrials.gov, NCT03158688, and is active but not recruiting. Findings: Between June 13, 2017, and June 25, 2018, 466 patients were enrolled, of whom 312 received KdD and 154 received Kd. At data cutoff (June 15, 2020), median follow-up was 27·8 months (IQR 25·6–29·5) for KdD and 27·0 months (13·2–28·6) for Kd. Median progression-free survival was 28·6 months (95% CI 22·7–not estimable [NE]) in the KdD group and 15·2 months (11·1–19·9) in the Kd group (hazard ratio 0·59 [95% CI 0·45–0·78], log-rank p

Background: Lenalidomide and bortezomib frontline exposure has raised a growing need for novel treatments for patients with relapsed or refractory multiple myeloma. Carfilzomib in combination with daratumumab has shown substantial efficacy with tolerable safety in relapsed or refractory multiple myeloma in a phase 1 study. In this study, we aimed to compare the efficacy and safety of carfilzomib, dexamethasone, and daratumumab versus carfilzomib and dexamethasone in patients with relapsed or refractory multiple myeloma. Methods: In this randomised, multicentre, open-label, phase 3 study, 466 patients recruited from 102 sites across North America, Europe, Australia, and Asia with relapsed or refractory multiple myeloma were randomly assigned 2:1 to carfilzomib, dexamethasone, and daratumumab (KdD) or carfilzomib and dexamethasone (Kd). All patients received twice per week carfilzomib at 56 mg/m2 (20 mg/m2; days 1 and 2 during cycle 1). Daratumumab (8 mg/kg) was administered intravenously on days 1 and 2 of cycle 1 and at 16 mg/kg weekly for the remaining doses of the first two cycles, then every 2 weeks for four cycles (cycles 3–6), and every 4 weeks thereafter. Patients received 40 mg dexamethasone weekly (20 mg for patients ≥75 years old starting on the second week). The primary endpoint was progression-free survival assessed by intention to treat. Adverse events were assessed in the safety population. This trial (NCT03158688) is registered with ClinicalTrials.gov, and is active but not recruiting. Findings: Between June 13, 2017, and June 25, 2018, 466 patients of 569 assessed for eligibility were enrolled. After median follow-up of approximately 17 months, median progression-free survival was not reached in the KdD group versus 15·8 months in the Kd group (hazard ratio 0·63; 95% CI 0·46–0·85; p=0·0027). Median treatment duration was longer in the KdD versus the Kd group (70·1 vs 40·3 weeks). Grade 3 or higher adverse events were reported in 253 (82%) patients in the KdD group and 113 (74%) patients in the Kd group. The frequency of adverse events leading to treatment discontinuation was similar in both groups (KdD, 69 [22%]; Kd, 38 [25%]). Interpretation: KdD significantly prolonged progression-free survival versus Kd in patients with relapsed or refractory multiple myeloma and was associated with a favourable benefit–risk profile.

Acknowledging the increasingly important role of whole-body MRI for directing patient care in myeloma, a multidisciplinary, international, and expert panel of radiologists, medical physicists, and hematologists with specific expertise in whole-body MRI in myeloma convened to discuss the technical performance standards, merits, and limitations of currently available imaging methods. Following guidance from the International Myeloma Working Group and the National Institute for Clinical Excellence in the United Kingdom, the Myeloma Response Assessment and Diagnosis System (or MY-RADS) imaging recommendations are designed to promote standardization and diminish variations in the acquisition, interpretation, and reporting of whole-body MRI in myeloma and allow response assessment. This consensus proposes a core clinical protocol for whole-body MRI and an extended protocol for advanced assessments. © 2019 Radiological Society of North America Inc.. All rights reserved.
