Efficacy and safety of frontline regimens for older transplant-ineligible patients with multiple myeloma: A systematic review and meta-analysis.


ABSTRACT:

Introduction

Several treatment options are available for the management of older adults with newly diagnosed patients with Multiple Myeloma (MM) who are ineligible for hematopoietic cell transplantation (tiMM). We aimed to identify treatment options that provide the best balance in terms of efficacy and safety.

Methods

We searched bibliographic databases and meeting libraries for search terms reflecting newly diagnosed and older and/or transplant-ineligible patients from inception to October 21, 2018. Phase II/III randomized trials comparing at least two first line treatment regimens for newly diagnosed tiMM were included. We extracted data on efficacy (progression free survival, PFS, overall survival and overall response rate) and safety (grade ¾ toxicities) and conducted network meta-analysis using Bayesian methods and random effects models. Relative ranking of treatment regimens was assessed using Surface under the cumulative ranking (SUCRA) probabilities.

Results

We identified 27 trials involving 12,194 patients. For PFS, the four most effective regimens were: Daratumumab, Bortezomib, Melphalan and Prednisone (SUCRA 0.960) followed by Daratumumab, lenalidomide and dexamethasone (Dara_RD, SUCRA 0.847), Bortezomib, melphalan, prednisone, thalidomide maintenance with bortezomib-thalidomide (SUCRA 0.834) and Bortezomib, Lenalidomide and Dexamethasone (SUCRA 0.739). Among these four most efficacious regimens, toxicity profile was most favorable for Dara_RD (median additional AEs per patient vs dexamethasone = 0.74; 95% CrI 0.51-1.17; SUCRA 0.430).

Conclusion

Among first line tiMM regimens, increasing efficacy is associated with increased toxicity. We provide relative ranking of these regimens for both efficacy and safety. Future studies should incorporate geriatric assessments and frailty biomarkers to refine treatment decision-making for each individual patient.
