ABSTRACT
BACKGROUND: Renal insufficiency (RI) is a key factor affecting the prognosis of multiple myeloma (MM) patients. Because the benefit of daratumumab for treating MM patients with RI remains unclear, our objective was to evaluate the efficacy of daratumumab on MM patients with RI.
METHODS: We conducted a systematic search of the PubMed, EMBASE, and Cochrane Library databases as of October 24, 2023. Two independent reviewers screened the article titles, abstracts, and full text to identify the randomized controlled trials (RCTs) meeting the inclusion and exclusion criteria. Meta-analyses were performed using RevMan version 5.4. Outcomes of interest were progression-free survival (PFS), overall survival (OS), complete response or better (≥CR), and minimal residual disease (MRD) negativity, all calculated as hazard ratios (HRs) or risk ratios (RRs) with 95% confidence intervals (CIs).
RESULTS: A total of 10 RCTs with 5003 patients were included. Add-on daratumumab improved PFS and OS among newly diagnosed MM (NDMM) patients with RI (HR 0.48 [95% CI: 0.36, 0.64, I2 = 65%] and HR 0.63 [95% CI: 0.48, 0.82, I2 = 0%]) as well as relapsed/refractory MM (RRMM)-RI patients, compared with the control group (HR 0.46 [95% CI: 0.37, 0.58, I2 = 0%] and HR 0.68 [95% CI: 0.51, 0.92, I2 = 0%]). In terms of the renal status, the efficacy of add-on daratumumab for MMRI patients was similar to that for MM patients with normal renal function. A prolonged PFS benefit for add-on daratumumab treatment versus the control was evident across all RRMM-RI subgroups, and the benefits tended to increase with the follow-up time.
CONCLUSIONS: Our results indicate that MM patients with RI could benefit from a daratumumab-added regimen regardless of MM status. Additional high-quality RCTs are still warranted to confirm our findings.
