Open-label, phase 2 study of blinatumomab after frontline R-chemotherapy in adults with newly diagnosed, high-risk DLBCL

This open-label, multicenter, single-arm, phase 2 study assessed the safety and efficacy of blinatumomab consolidation therapy in adult patients with newly diagnosed, high-risk diffuse large B-cell lymphoma (DLBCL; International Prognostic Index 3–5 and/or double-/triple-hit or double MYC/BCL-2 expressors) who achieved complete response (CR), partial response (PR), or stable disease (SD) following run-in with 6 cycles of R-chemotherapy (NCT03023878). Of the 47 patients enrolled, 28 received blinatumomab. Five patients (17.9%) experienced grade 4 treatment-emergent adverse events of interest (neutropenia, n = 4; infection, n = 1). Two deaths reported at the end of the study were unrelated to treatment with blinatumomab (disease progression, n = 1; infection, n = 1). 3/4 patients with PR and 4/4 patients with SD after R-chemotherapy achieved CR following blinatumomab. Consolidation with blinatumomab in patients with newly diagnosed, high-risk DLBCL who did not progress under R-chemotherapy was better tolerated than in previous studies where blinatumomab was used for treatment of patients with lymphoma

Incorporating genetic and clinical data into the prediction of thromboembolism risk in patients with lymphoma

Background: The incorporation of genetic variables into risk scores for predicting venous thromboembolic events (VTE) could improve their capacity to identify those patients for whom thromboprophylaxis would be most beneficial. Proof-of-concept of this is provided by the TiC-ONCO score for predicting the risk of VTE in patients with solid tumours. Our aim was to develop a similarly improved tool-the TiC-LYMPHO score-for predicting VTE in patients with lymphoma. Methods: In a retrospective observational study of 208 patients with lymphoma, 31 (14.9%) were found to have experienced an episode of VTE either at the time of diagnosis or over the next 6 months. Clinical variables associated with VTE, determined via logistic regression analysis, plus the same genetic variables included in the TiC-ONCO score, were used to build the TiC-LYMPHO score algorithm. The sensitivity, specificity, predictive values and AUC of the TiC-LYMPHO, the Khorana and ThroLy scores were compared in the same population. Results: The TiC-LYMPHO score showed a significantly higher AUC, sensitivity and NPV (0.783, 95.35% and 97.98% respectively) than the other scores. The ThroLy score showed a significantly higher specificity (96.43% vs. 54.49%; p < 0.0001) and PPV (37.50% vs. 26.36%; p = 0.0147) than the TiC-LYMPHO score, whereas its AUC, sensitivity and NPV were significantly lower (0.579, 19.35% and 86.48%, respectively). Conclusion: These results show that by incorporating genetic and clinical data into VTE risk assessment, the TiC-LYMPHO score can categorize patients with lymphoma better in terms of their risk of VTE and allow individualized thromboprophylaxis to be prescribed

Aprepitant in refractory pruritus of systemic lymphoproliferative disorders

araneoplastic pruritus represents a frequent symptom in the debut or progression of lymphoproliferative disorders. It affects approximately 30% of patients with Hodgkin lymphoma and 15% of patients with non-Hodgkin lymphoma.1 Aprepitant has shown promising results in the treatment of refractory pruritus of primary cutaneous T-cell lymphomas (CTCL)
