Purpose
L-MIND trial has demonstrated efficacy of tafasitamab plus lenalidomide in patients with relapsed/refractory diffuse large B-cell lymphoma (r/r DLBCL). However, real-world evidence comparing tafasitamab plus lenalidomide to standard salvage therapies remains limited. Therefore, we conducted an external control arm study to evaluate clinical effectiveness of tafasitamab plus lenalidomide compared with ICE (ifosfamide, carboplatin, etoposide) regimen in South Korea.
Materials and Methods
Individual patient-level data from L-MIND trial and Samsung Medical Center–Lymphoma Cohort Studies (SMC-LCS) registry in South Korea were analyzed to identify DLBCL patients who received tafasitamab plus lenalidomide or ICE as second- to fourth-line therapy. Primary endpoint was overall survival (OS), while secondary endpoints included progression-free survival (PFS), time to next treatment (TTNT), duration of response (DoR), objective response rate (ORR), and complete response rate (CRR). After applying inverse probability of treatment weighting (IPTW), time-to-event and binary outcomes were analyzed using Cox and logistic regression models, respectively.
Results
A total of 76 patients in L-MIND and 39 patients in SMC-LCS were analyzed. After IPTW, median OS was 34.1 months (95% confidence interval [CI], 18.6 to not reached) for tafasitamab plus lenalidomide and 6.4 months (95% CI, 0.3 to 13.9) for ICE (hazard ratio [HR], 0.33; 95% CI, 0.20 to 0.53). HRs were 0.33 (95% CI, 0.20 to 0.54) for PFS, 0.42 (95% CI, 0.26 to 0.66) for TTNT, and 0.17 (95% CI, 0.08 to 0.35) for DoR. Odds ratios were 3.17 (95% CI, 1.37 to 7.32) for ORR, and 2.87 (95% CI, 1.06 to 7.78) for CRR.
Conclusion
Tafasitamab plus lenalidomide showed favorable outcomes over ICE, suggesting a clinically meaningful treatment option for r/r DLBCL in South Korea.

Purpose IMC-002 is a fully human cluster of differentiation 47-targeted immunoglobulin G4 monoclonal antibody, designed to minimize off-target effects. This study (NCT05276310) assessed its safety/tolerability and preliminary anti-tumor activity in patients with advanced solid tumors who were not eligible for or had progressed on standard treatment.
Materials and Methods We report results from the initial 3+3 design dose-escalation part of a two-part phase 1, open-label, dose-escalation/expansion study. IMC-002 was administered intravenously every 2 weeks at four doses (5, 10, 20, and 30 mg/kg). The primary objective was to assess safety/tolerability, including maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D). Secondary objectives included pharmacokinetics and clinical activity, including best overall response (BOR), disease control rate (DCR), and clinical benefit rate (CBR).
Results Twelve patients were included in total, with three per dose level. Most patients (11/12) had stage IV disease; 7/12 had received three prior systemic therapies. No dose-limiting toxicities were observed and MTD was not reached. The most common treatment-related adverse events were rash (9/12), vitreous floaters (8/12), and (hemolytic) anemia (5/12). There was no treatment-related thrombocytopenia, neutropenia, or infection. IMC-002 had dose-proportional pharmacokinetics, achieving steady state levels from cycle 2. BOR was stable disease in six patients (DCR 50.0%). CBR was 33% (four patients maintaining disease control for ≥ 6 months).
Conclusion IMC-002 demonstrated favorable safety/tolerability at doses of 5-30 mg/kg every 2 weeks. RP2D was defined as 20 mg/kg every 3 weeks. Preliminary anti-tumor activity was observed, with a CBR of 33%.
