Episode 72. frontMIND Trial in DLBCL with Dr. Charles Herbaux

Episode Overview

For the second time in two decades, a phase 3 trial has shown a statistically significant improvement over R-CHOP in newly diagnosed diffuse large B-cell lymphoma (DLBCL). In this episode, Eddie, Raj, and Ashwin sit down with Professor Charles Herbaux to unpack the data, debate the clinical implications, and ask the question that's on every hematologist's mind: is this enough to change practice?

Background: Setting the Stage for Tafasitamab

Before diving into frontMIND, the episode provides context on tafasitamab, a CD19-targeting monoclonal antibody

L-MIND (Phase 2 — relapsed/refractory DLBCL):

81 patients with R/R DLBCLORR 58%, complete response rate 41%Established activity of tafasitamab + lenalidomide in the relapsed settinghttps://pubmed.ncbi.nlm.nih.gov/32511983/First-MIND (Phase 1b — frontline DLBCL, IPI 2–5):

66 patients randomized: tafa-R-CHOP (n=33) vs. tafa-len-R-CHOP (n=33)ORR: 75.8% vs. 81.8%, respectivelySerious treatment-emergent adverse events: 42.4% vs. 51.5%Provided the signal (and the safety caution) to move to phase 3https://pubmed.ncbi.nlm.nih.gov/37369099/

The frontMIND Trial

Design: Phase 3, double-blind, placebo-controlled randomized trial

Intervention: R-CHOP + tafasitamab (12 mg/kg IV days 1, 8, 15 per cycle) + lenalidomide (25 mg/day, days 1–10 per cycle)Control: R-CHOP + placebosGCSF mandatory (given double-blind design); VTE prophylaxis (heparin or aspirin) mandatory given lenalidomideEnrollment: May 2021 – March 2023; 899 patients randomizedPrimary endpoint: Investigator-assessed progression-free survival (PFS)Patient Population:

Age 18–80; DLBCL or high-grade B-cell lymphoma, IPI 3–5Median age: 65 years96% advanced stage; 54% bulky disease; 31% ECOG PS 2; 82% elevated LDH55% IPI 3 / aaIPI 2; 43% IPI 4–5 / aaIPI 38% double/triple hit — a high-risk subgroup included despite R-CHOP being the controlBroad histologic inclusion: transformed lymphoma, grade 3B FL, T-cell/histiocyte-rich LBCL, EBV+ DLBCL, ALK+ LBCL, HHV8+ DLBCL Note: On retrospective central review, ~7% of patients had a different histology (roughly half had FL grade 1–3A), underscoring the diagnostic challenges in DLBCL~40% received pre-phase steroids; 8% rituximab; 4% vincristine prior to cycle 1
