Impact of ixazomib-lenalidomide-dexamethasone therapy on overall survival in multiple myeloma patients: Analysis of the emerging-markets subgroup of the TOURMALINE-MM1 trial.

ABSTRACT: Ixazomib-lenalidomide-dexamethasone (ixazomib-Rd) showed clinical efficacy over placebo-Rd in patients with relapsed/refractory multiple myeloma (MM) in the TOURMALINE-MM1 trial. Over a median follow-up of ∼85 months, as patients showed disease progression, they received subsequent novel therapies that confounded the overall survival (OS) benefit. Here, we conducted a post hoc analysis in 148 patients from seven countries defined as emerging markets, with limited access to novel therapies for MM during the trial period, to describe the impact of these therapies on OS. Patients were randomised to ixazomib-Rd (n = 71) or placebo-Rd (n = 77). The median progression-free survival (PFS) was 18.7 versus 10.2 months, with ixazomib-Rd versus placebo-Rd (hazard ratio [HR], 0.504; p
