BEIJING, September 13, 2024--(BUSINESS WIRE)--Latest data of InnoCare’s (HKEX: 09969; SSE: 688428) orelabrutinib were presented at the European Society for Medical Oncology (ESMO) Congress 2024.

Oral Presentation

A Prospective Study of Orelabrutinib plus Obinutuzumab (O2) in Treatment-naïve Marginal Zone Lymphoma (MZL): Preliminary Analysis on Efficacy and Safety (Abstract No.: 815MO)

This prospective study evaluated a chemotherapy-free regimen of orelabrutinib plus anti-CD20 antibody, obinutuzumab, in treatment-naive MZL.

Currently, there is no well-established standard first-line treatment for symptomatic MZL patients. The preliminary data demonstrated that the combination of orelabrutinib plus obinutuzumab shows promise in treatment-naive MZL. At a median follow-up of 5.4 months, the best objective response rate (ORR) was 100% (57.1% complete response rate (CRR)), with a good safety profile.

Poster Presentation

1. Orelabrutinib-based Regimens in Chronic Lymphocytic Leukemia with Comorbidities: A Real-World Study (Abstract No.: 840P)

This study aimed to evaluate the efficacy of orelabrutinib-based regimens for chronic lymphocytic leukemia (CLL) with comorbidities in a real-world setting. The outcome was the hematologic response (HR) rate. Orelabrutinib-based regimens demonstrated encouraging HR and were well tolerated in CLL with comorbidities, providing valuable insights for clinical management.

Eighty percent of patients have comorbidities. At a median follow-up of 12.7 months, 93.3% patients achieved an HR. Among the different orelabrutinib-based regimens, HR was achieved in 100% of patients receiving orelabrutinib monotherapy and 85.7% of those receiving orelabrutinib + chemotherapy. No serious adverse events occurred in the patients with comorbidities.

2. Efficacy and Safety of Orelabrutinib plus R-CHOP-like Regimens for Treatment-naïve Diffuse Large B-cell Lymphoma with Double Expression (Abstract No.: 819P)

The first-line combination of orelabrutinib plus R-CHOP-like regimens was effective and well-tolerated in patients with diffuse large B-cell lymphoma (DLBCL) harboring double expression.

The complete response rate (CRR) was 93.8% at the end of treatment. After a median follow-up of 13.0 months, the one-year progression-free survival (PFS) and overall survival (OS) rates were 93.3% and 100.0%, respectively.

The following studies were also selected as poster presentations at the ESMO Congress 2024.

  1. Fixed-duration Orelabrutinib plus Bendamustine and Rituximab versus Continuous Bruton Tyrosine Kinase Inhibitor (BTKi) in Treatment-naïve Chronic/small Lymphocytic Leukemia (CLL/SLL): A Multicenter, Nonrandomized, Pragmatic Clinical trial (Abstract No.: 846TiP)

  2. Orelabrutinib combined with Rituximab for the Treatment of Elderly patients with newly diagnosed non-GCB diffuse large B-cell lymphoma (DLBCL) under the guidance of genetic subtype: A prospective, multicenter, single-arm, response-adaptive clinical study (Origin) (Abstract No.: 844TiP)
