Clinical data on the efficacy and safety of orelabrutinib in treatment-naïve (TN) chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) patients from the United States and Europe was released for the first time. A series of clinical studies on orelabrutinib covered multiple hematological malignancies, including CLL/SLL, marginal zone lymphoma (MZL), mantle cell lymphoma (MCL), diffuse large B-cell lymphoma (DLBCL), and primary central nervous system lymphoma (PCNSL). These findings further support the excellent efficacy and safety of orelabrutinib. Poster Presentation: 1. Orelabrutinib for the Treatment of Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma: Safety and Efficacy Results from a Global Phase 1/2 Study. (No. PF610) This study is to evaluate the safety and efficacy of orelabrutinib in patients with CLL/SLL from the United States and Europe. The researchers include multiple world-renowned oncology centers such as Mayo Clinic. Results are consistent with the prior report in Chinese patients, confirming the efficacy and safety of orelabrutinib for CLL/SLL in a global population. In evaluable TN CLL/SLL patients (median follow-up 38.1 months), ORR was 100%, with 36-month PFS rate at 94.4% and 36-month OS rate at 100% respectively. In evaluable R/R CLL/SLL patients (median follow-up 36.8 months), ORR was 86.7%, with 36-month PFS rate 77.9% and the 36-month OS rate 80.1% respectively. Orelabrutinib demonstrates high kinase selectivity, alleviates off-target inhibition, and reduces cardiovascular, bleeding, and hematologic adverse events. 2. Long-term Follow-up of Orelabrutinib in Patients with Relapsed or Refractory Marginal Zone Lymphoma (No. PF949) With long-term follow-up, orelabrutinib demonstrated rapid and durable responses, indicating sustained therapeutic benefit in patients with r/r MZL. Importantly, no new safety signals were observed during extended follow-up. At a median follow-up of 36.8 months, the investigator-assessed ORR was 58.9%, median PFS was 44.4 months, and the 36-month OS rate was 84.7%. 3. Risk-Adapted Management with Obinutuzumab and Orelabrutinib with or without Lenalidomide in Untreated Marginal Zone Lymphoma: First Report of a Prospective, Phase II, Multi-Centre (MAGIC) Study (No. PS2037) This is a prospective, phase II, multicenter study. The preliminary results demonstrated encouraging efficacy and a manageable safety profile in patients with previously untreated MZL. Patients with an MZL-IPI score of 0–2 received obinutuzumab plus orelabrutinib (O2 regimen). Those with a score of 3–5 received obinutuzumab, orelabrutinib and lenalidomide (RO2 regimen). In patients who completed six cycles of induction therapy, the CRR was 85.7% and ORR was 95.3% in the O2 group, and the CRR was 71.4% and ORR was 85.7% in the RO2 group. The study is ongoing, and updated efficacy and safety data will be reported in due course. 4. Polatuzumab Vedotin Combined with Orelabrutinib and Rituximab (PRO Regimen) as Frontline Therapy in Very Elderly and Frail Patients with DLBCL: Updated Results from a Phase II Study (No. PS2072) Results support the PRO regimen, which includes orelabrutinib, as a feasible strategy for vulnerable patients. Patients had a median age of 78 years. At the completion of combination therapy, the CR rate was 91.7%. With a median follow-up of 7.0 months, neither the median PFS nor the median OS has been reached. The estimated 9-month PFS rate was 92.8%. Most other hematologic and non-hematologic toxicities were confined to Grade 1-2 and were clinically manageable with supportive care. 5. The Real-World Efficacy of Bruton’s Tyrosine Kinase Inhibitors Plus High-Dose Methotrexate-Based Induction Treatment for Untreated Primary CNS Lymphoma: A Single-Center Retrospective Analysis (No. PF1035) This analysis aims to evaluate the efficacy of BTKi like orelabrutinib plus HD-MTX-based chemotherapy regimens as induction treatment for newly diagnosed PCNSL patients in a real-world cohort. The results show that the ORR after induction treatment was 88.6% and the CR rate was 81.1%. There was no significant difference in PFS among the three BTKi, but a significant improvement in OS was observed in the orelabrutinib group (HR 0.26, P = 0.016). These results support the use of BTKi-containing treatment regimens as a first-line therapy for PCNSL in clinical practice.
