THE BRAF INHIBITOR VEMURAFENIB COMBINED WITH RITUXIMAB PRODUCES A HIGH RATE OF DEEP AND DURABLE REMISSIONS IN RELAPSED OR REFRACTORY HAIRY CELL LEUKEMIA: UPDATED RESULTS OF A PHASE-2 TRIAL

Conclusion: Vemurafenib plus rituximab is a brief, safe and non-myelotoxic regimen that induces MRD-negative durable responses in the majority of relapsed/refractory HCL patients. Randomized testing of this regimen against the chemotherapy-based standard of care in the frontline setting is warranted.

OBINUTUZUMAB PLUS DHAP FOLLOWED BY AUTOLOGOUS STEM CELL TRANSPLANTATION PLUS OBINUTUZUMAB MAINTENANCE PROVIDES A HIGH MRD RESPONSE RATE IN UNTREATED MCL PATIENTS, LYMA-101 TRIAL - A LYSA TRIAL

Conclusion: The Lyma-101 trial successfully achieved its primary endpoint (84.9% of MRD BM negativity after induction) and demonstrates the high efficacy of O-DHAP as induction chemotherapy regimen with an unprecedented high level of MRD negativity. Longer FU is needed to evaluate patient outcome after O-DHAP/ASCT/Obinutuzumab on-demand maintenance. However, both PFS and OS are highly encouraging at one year.

POLATUZUMAB VEDOTIN (POLA) + OBINUTUZUMAB (G) AND LENALIDOMIDE (LEN) IN PATIENTS (PTS) WITH RELAPSED/REFRACTORY (R/R) FOLLICULAR LYMPHOMA (FL): INTERIM ANALYSIS OF A PHASE IB/II TRIAL

Conclusion: The safety profile of Pola-G-Len is consistent with known profiles of the individual drugs. Response rates at EOI with Pola-G-Len are promising, with high CR compared with available R/R FL treatment.

TREATMENT-DEPENDENCE OF HIGH-RISK GENE EXPRESSION SIGNATURES IN DE NOVO FOLLICULAR LYMPHOMA

Conclusion: We identified a significant chemotherapy-dependent interaction for two high-risk signatures in de novo FL. These data suggest that high-risk biology may react differently to different chemotherapy backbones, highlighting the challenges of building high-risk signatures for pts independent of treatment.

EFFICACY AND SAFETY OF PROLONGED MAINTENANCE WITH SUBCUTANEOUS RITUXIMAB IN PATIENTS WITH RELAPSED OR REFRACTORY INDOLENT NON-HODGKIN LYMPHOMA: RESULTS OF THE PHASE III MABCUTE STUDY

Conclusion: MabCute was unable to fully address the primary study endpoint of PFSrand due to the limited number of events observed. The safety profile of R-SC during prolonged maintenance was consistent with the known profile of R-SC.

IMPROVED OUTCOMES IN PATIENTS (PTS) WITH BCL2-POSITIVE DIFFUSE LARGE B-CELL LYMPHOMA (DLBCL) TREATED WITH VENETOCLAX (VEN) PLUS R-CHOP: RESULTS FROM THE PHASE 2 CAVALLI STUDY

Conclusion: Addition of Ven to R-CHOP in 1L DLBCL resulted in improved efficacy in BCL2 IHC+ pts compared with matched GOYA controls. A higher rate of cytopenia, FN and infections was observed in CAVALLI vs GOYA; however, there was no increase in risk of death, and the RDI of chemotherapy was maintained at similar levels.

REAL-WORLD TREATMENT PATTERNS OF PATIENTS DIAGNOSED WITH DIFFUSE LARGE B-CELL LYMPHOMA (DLBCL) IN THE UNITED STATES (US)

Conclusion: This real-world study of DLBCL patients suggests that a substantial proportion of these patients require treatment beyond 1L, highlighting the unmet need within this population.
