Development Pipeline

Zanubrutinib is a small molecule inhibitor of Bruton’s tyrosine kinase (BTK) discovered by BeiGene scientists that is currently being evaluated globally in a broad clinical program as a monotherapy and in combination with other therapies to treat various B-cell malignancies.

Tislelizumab is a humanized monoclonal antibody against the immune checkpoint receptor PD-1 that is currently being evaluated in pivotal clinical trials globally and in China and for which we plan to commence additional pivotal trials as a monotherapy and in combination with standard of care to treat various solid and hematological cancers.

Pamiparib is a selective small molecule inhibitor of poly ADP-ribose polymerase 1 (PARP1) and PARP2 enzymes that is being evaluated as a potential monotherapy and in combinations for the treatment of various solid tumors. We believe that pamiparib has the potential to be differentiated from other PARP
inhibitors because of its brain penetration, greater selectivity, strong DNA-trapping activity, and good oral bioavailability demonstrated in preclinical models.

Ociperlimab is an investigational humanized IgG1-variant monoclonal antibody directed against TIGIT. An immune checkpoint molecule, ociperlimab is currently being investigated in two global Phase 3 clinical trials, the AdvanTIG-301 (NCT04866017) and AdvanTIG-302 (NCT04746924) trials, in combination with tislelizumab in NSCLC. To date, approximately 800 subjects have been enrolled across the ociperlimab development program, which includes six global trials in patients with lung cancers, esophageal squamous cell carcinoma, and cervical cancer.

BGB-11417 is an investigational small molecule Bcl-2 inhibitor. We have completed preclinical and investigational new drug (IND)-enabling studies of BGB-11417, which demonstrated potent activity and high selectivity against the pro-apoptotic protein Bcl-2. The molecule appears to be more potent than venetoclax and shows the potential to overcome resistance to venetoclax. Further, it is more selective than venetoclax for Bcl-2 relative to Bcl-xL. Finally, we believe that it is well-positioned to be combined with zanubrutinib.

BGB-A445 is an investigational agonistic antibody directed to the OX40 antigen. BGB-A445 is a non-ligand competing antibody that does not disrupt OX40 to OX40 ligand engagement. Preclinical experiments showed that BGB-A445 had increasing effectiveness at higher doses versus an antibody that was ligand-competing, which showed falling effectiveness at higher doses. BGB-A445 has also showed in preclinical tests the potential to be combined with several agents, such as tislelizumab, as well as a TLR9 agonist, a PI3Kδ inhibitor, sitravatinib, and chemotherapy.

BGB-A425 is an investigational humanized IgG1-variant monoclonal antibody against T-cell immunoglobulin and mucin-domain containing-3 (TIM-3). BGB-A425 is being evaluated in combination with tislelizumab.

BGB-15025 is an investigational small molecule inhibitor of HPK1, which is a key negative feedback regulator of TCR signaling. Inhibition of HPK1 leads to enhanced T-cell activation pre-clinically. In addition, preclinical studies showed that BGB-15025 exhibits combination activity with tislelizumab and has a wide therapeutic window.

Sitravatinib is an investigational spectrum-selective kinase inhibitor, which potently inhibits receptor tyrosine kinases, including RET, TAM family receptors (TYRO3, Axl, MER), and split family receptors (VEGFR2, KIT). In January 2018, we entered into an exclusive license agreement with Mirati Therapeutics, Inc. (Mirati) for the development, manufacturing and commercialization of Mirati’s sitravatinib in Asia (excluding Japan and certain other countries), Australia and New Zealand.

Zanidatamab, a novel investigational Azymetric™ bispecific antibody targeting HER2, is currently in late-stage clinical development with Zymeworks Inc. BeiGene has development and commercial rights to zanidatamab in Asia (excluding Japan), Australia, and New Zealand.

Lifirafenib is an investigational novel small molecule inhibitor with RAF monomer and dimer inhibition activities. We believe that lifirafenib as monotherapy or in combination with other agents may have potential for treating various malignancies such as melanoma, NSCLC, and endometrial cancer. Lifirafenib has shown antitumor activity in preclinical models and in cancer patients with tumors harboring BRAF V600E mutations, non-V600E BRAF mutations or KRAS/NRAS mutations. We have been developing lifirafenib for the treatment of cancers with aberrations in the mitogen-activated protein kinase (MAPK), pathway, including BRAF gene mutations and KRAS/NRAS gene mutations where first generation BRAF inhibitors are not effective.

BeiGene is working with SpringWorks Therapeutics, Inc. (SpringWorks) in a global clinical collaboration to evaluate the safety, tolerability, and preliminary efficacy of lifirafenib in combination with SpringWorks’ investigational MEK inhibitor, mirdametinib (PD-0325901), in patients with advanced solid tumors.

In addition to the collaboration, BeiGene and SpringWorks formed a separate company, MapKure, LLC, to develop BGB-3245, an investigational, selective next-generation RAF kinase inhibitor discovered by BeiGene scientists.
