Efficacy and safety of intravenous daratumumab-based treatments for AL amyloidosis: a systematic review and meta-analysis.


ABSTRACT:

Background

Intravenous daratumumab (DARA IV) has been increasingly used in the treatment of amyloid light-chain (AL) amyloidosis. However, the outcomes for patients administered with DARA IV have not been aggregated. The objective of this systematic review and meta-analysis was to investigate the efficacy and safety of DARA IV for AL amyloidosis.

Methods

We searched Medline, EMBASE, Cochrane Library and Web of Science up to 17 June 2021. Response rates and survival rates, and the corresponding 95% confidence intervals (CIs) were pooled and calculated using a fixed-effects model.

Results

Thirty studies (5 cohort studies and 25 single-arm studies) with 997 patients were included. In patients receiving DARA IV-based treatments, very good partial response or better response rate, complete response rate, very good partial response rate, partial response rate and overall response rate were 66% (95% CI, 62-69%), 30% (95% CI, 23-36%), 40% (95% CI, 33-46%), 17% (95% CI, 14-21%), and 77% (95% CI, 73-80%), respectively. Cardiac and renal responses were 41% (95% CI, 34-49%) and 43% (95% CI, 32-54%), respectively. 58% (95% CI, 49-66%) of patients achieved PFS one year or longer. 2.5% (range, 1-10.0%) of patients experienced grade 3 or 4 adverse events, of which the most common adverse event was lymphocytopenia (range, 13.6-25.0%).

Conclusion

This study supports the efficacy and safety of DARA IV for the treatment of patients with AL amyloidosis.
