Highly selective and irreversible BTK inhibitor currently being evaluated in a broad clinical program in China and the U.S. for the treatment of various B-cell malignancies and autoimmune diseases. 

Orelabrutinib is an orally available potent BTK inhibitor that irreversibly binds to BTK to induce downstream kinase inactivation and cell death. Orelabrutinib was designed with a single ring at the scaffold center instead of a fused bi-cycle core. We believe this unique feature conveys higher selectivity for Orelabrutinib which should result in fewer off-target side effects that potentially lead to treatment discontinuation.

The Role of BTK

BTK is a non-receptor tyrosine kinase that plays a key role in signaling in various cell surface receptors, most prominently the B-cell antigen receptor (BCR). The BCR signaling pathway is crucial for the proliferation and survival of leukemic cells in lymphomas. BTK inhibitors selectively block kinase activities and regulate signaling pathways to interfere with B-cell development and thereby control oncogenic progression of various B-cell malignancies.

BTK is a promising target for the treatment of autoimmune diseases such as RA and SLE due to its role in mediating both B-cell and Fc receptor signaling. Specifically, BTK plays key roles in both B-cells and macrophages, which are the two major cell types contributing to SLE pathogenesis.

Orelabrutinib Clinical Trials

Orelabrutinib Combinations

We intend to identify and develop promising combination therapies to leverage Orelabrutinib’s favorable safety profile demonstrated by clinical data to date.

We have initiated a Phase I trial of Orelabrutinib in combination with MIL62, a next-generation CD20 antibody for FL patients in China and plan to explore other promising combination therapies with agents such as BCL-2 and PI3K inhibitors for the treatment of B-cell malignancies.

Potent and selective pan-FGFR inhibitor that we are developing for the treatment of various types of solid tumors. ICP-192 is one of the most advanced clinical stage pan-FGFR inhibitors being developed in China. We developed ICP-192 with a unique structure to achieve enhanced anti-tumor efficacy while limiting in vivo drug exposure.

We will initially focus the expansion studies on cholangiocarcinoma with FGFR2 fusions and urothelial cancer with FGFR2/3 genetic alterations. We plan to collect further data to assess whether ICP-192 will be a potential treatment option for patients with FGFR mutation in combination with therapeutic agents such as immune checkpoint inhibitors.



The Role of FGFRs
  • FGFRs are a family of tyrosine kinase receptors, which includes FGFR1-4, that play a key role in the regulation of cell proliferation and cell survival.
  • Pan-FGFR inhibitors that selectively bind to and inhibit FGFRs can block FGFR-related signal pathways and thereby control tumor cell proliferation and tumor cell death.

ICP-105 is a highly selective FGFR4 inhibitor that can effectively bind to FGFR4, inhibit FGF19-overexpression mediated activation of FGFR4 signaling in HCC and exert its anti-neoplastic effect by blocking the activation of the downstream ERK signaling pathway. We are developing ICP-105 primarily for the treatment of advanced hepatocellular carcinoma (HCC) with FGFR4 pathway overactivation. 



The Role of FGFR4

FGFR4 is a tyrosine kinase receptor that plays a key role in the regulation of cell proliferation, metabolism and bile acid biosynthesis. Aberrant activation of FGFR4 is associated with the overexpression of its ligand FGF19 in hepatocytes. Such activation has been found to drive cancer development and solid tumor growth. FGFR4-specific inhibitors suppress the aberrant activation of FGFR4 and inhibit FGFR4-mediated signaling, leading to an inhibition of cell proliferation in FGF19-overexpressing tumors cells.

ICP-105 Clinical Trials

ICP-105 is under clinical evaluation in a Phase I dose escalation trial to identify the MTD and/or OBD in China. We plan to initiate an open-label Phase IIa study to evaluate the safety and efficacy of ICP-105 in HCC patients with FGFR4 pathway overactivation. We also plan to explore the use of ICP-105 in combination with immune checkpoint inhibitors for the treatment of advanced HCC with FGFR4 pathway overactivation.
