BEIJING--()--Data of InnoCare’s (HKEX: 09969; SSE: 688428) robust pipelines were presented at the European Hematology Association (EHA) 2023 Hybrid Congress.

Oral Presentation:

Orelabrutinib, an irreversible inhibitor of Bruton’s Tyrosine Kinase, for treatment of Primary Immune Thrombocytopenia: results of a Randomized, Open-label Phase II Study

Abstract Number: S299

This study is aiming to evaluate the efficacy, safety and tolerability of orelabrutinib in patients with persistent or chronic primary immune thrombocytopenia (ITP). The primary endpoint was the percentage of patients who achieved at least two consecutive platelet counts ≥50x109/L without rescue medication in the 4 weeks before the elevated platelet count.

As of cut-off date on 6 Feb 2023, 33 patients were enrolled. Both 50mg QD and 30mg QD of orelabrutinib were safe in the treatment of patients with ITP. Generally, patients with orelabrutinib 50mg QD responded rapidly with better efficacy, especially in those who had responded to previous glucocorticoids (GC) / intravenous immunoglobulin (IVIG) therapies.

Overall 36.4% (12/33) patients met the primary endpoint, 40% (6/15) at the 50mg arm reached primary endpoint. Among 12 patients with primary endpoint response, 83.3% (10/12) patients achieved durable response defined as the percentage of patients with platelet count ≥50x109/L for at least 4 of the 6 visits between 14-24 weeks.

Among the 22 patients with previous response to GC or IVIG, 75.0% at the 50mg arm achieved the primary endpoint.

Orelabrutinib was safe in the treatment of ITP. Treatment related adverse events (TRAEs) were grade 1 or 2.

ORIENT study: regimen of orelabrutinib plus R-CHOP-like for patients with newly diagnosed untreated non-GCB DLBCL

Abstract Number: P1196

This study aimed to analyze efficacy and safety of orelabrutinib plus R-CHOP-like for untreated non-germinal center B-cell-like diffuse large B-cell lymphoma (non-GCB DLBCL) patients who benefited from induction therapy of orelabrutinib plus rituximab.

Despite preliminary, orelabrutinib+rituximab achieved high adaptability response in a short-term treatment for newly diagnosed non-GCB DLBCL. Orelabrutinib+R-CHOP regimen achieved high complete remission rates and demonstrated favorable safety profiles in patients who benefited from orelabrutinib+rituximab induction therapy.

Poster Presentation 2:

Preliminary Findings of A Phase II study of Chemo-free combination of Pomalidomide, Orelabrutinib, Rituximab with Sequential high-dose Methorexate in Newly Diagnosed Primary CNS Lymphoma

Abstract Number: P1165

This is the first study to treat newly diagnosed primary central nervous system lymphoma (PCNSL) with a targeted therapy combination before chemotherapy. Pomalidomide, orelabrutinib and rituximab produced a high overall response rate (ORR) with good tolerance. This suggested the potential of noncytotoxic first-line therapies for PCNSL.

About Orelabrutinib

Orelabrutinib is a highly selective BTK inhibitor developed by InnoCare for the treatment of cancers and autoimmune diseases.

On Dec. 25, 2020, orelabrutinib received conditional approval from the China National Medical Products Administration (NMPA) in two indications: the treatment of patients with relapsed/refractory chronic lymphocytic leukemia (CLL) /small lymphocytic lymphoma (SLL), and the treatment of patients with relapsed/refractory mantle cell lymphoma (MCL). At the end of 2021, orelabrutinib was included into National Reimbursement Drug list to benefit more lymphoma patients. On Nov. 22, 2022, orelabrutinib was approved for the treatment of R/R MCL in Singapore. On April 20, 2023, orelabrutinib was approved for the treatment r/r MZL in China.

In addition to the approved indications, multi-center, multi-indication clinical trials are underway in the US and China with orelabrutinib as monotherapy or in combination therapies, such as first line treatment of MCD subtype of diffuse large B-cell lymphoma (DLBCL).

Orelabrutinib was granted as Breakthrough Therapy Designation for the treatment of r/r MCL by U.S. Food and Drug Administration (FDA). Patient enrollment of Phase II registrational trial for R/R MCL was completed in the U.S.

In addition, orelabrutinib’s global phase II studies for the treatment of Multiple Sclerosis (MS), and clinical trials for the treatment of SLE, Primary Immune Thrombocytopenia (ITP) achieved proof of concept (PoC), and orelabrutinib’s phase II study for the treatment of Neuromyelitis Optica Spectrum Disorder (NMOSD) is ongoing in China.
