BeiGene to Present Latest Findings in Robust Lung Cancer Portfolio at ESMO Congress 2021

BeiGene, Ltd. (NASDAQ: BGNE; HKEX: 06160), a global biotechnology company focused on developing and commercializing innovative medicines worldwide, today announced that clinical results and subgroup analyses from the Company’s robust lung cancer program will be presented at the European Society for Medical Oncology (ESMO) Congress 2021.

“We continue to make meaningful progress with our deep immuno-oncology portfolio, including our lung cancer program of seven Phase 3 trials in NSCLC. Driven by growing clinical insights, we are working to accelerate the development of tislelizumab in novel combinations in lung cancer, including with our internally discovered potent investigational anti-TIGIT antibody ociperlimab and therapeutic agents from collaborations, such as sitravatinib,” commented Yong (Ben) Ben, M.D., Chief Medical Officer, Immuno-Oncology at BeiGene. “In addition, our scientists are exploring new modalities for potential combinations with tislelizumab in lung cancer and other solid tumors, and with the ongoing Novartis collaboration, tislelizumab can be leveraged with their oncology pipeline for more combination opportunities. We plan to work to realize the therapeutic potential of this differentiated checkpoint inhibitor through combinations in various tumor types for patients worldwide.”

Broad Lung Cancer Program Focused on Tislelizumab Combination Treatments

BeiGene is pursuing diverse mechanisms of action in combination with tislelizumab to complement targeting of the PD-1 pathway for potentially improved clinical outcomes or to overcome resistance associated with disease progression.

In NSCLC, many patients who have achieved a response to front-line anti-PD-1 antibody treatment eventually relapse due to resistance. Through its collaboration with Mirati Therapeutics, BeiGene is investigating the combination of tislelizumab and sitravatinib, a spectrum-selective tyrosine kinase inhibitor potentially capable of reversing immunosuppressive tumor microenvironment to overcome immune resistance. BeiGene is conducting a Phase 3 trial of this novel combination in NSCLC, and clinical results from an ongoing Phase 1b trial in patients with metastatic NSCLC, both naïve and refractory or resistance to anti-PD-(L)1 treatment, will be presented at ESMO Congress 2021.

Another novel combination of tislelizumab that BeiGene is investigating in lung cancer is with ociperlimab, a potent, Fc-intact investigational anti-TIGIT-antibody in Phase 3 clinical development. TIGIT is a co-inhibitory immune checkpoint receptor expressed on multiple immune cells and has recently emerged as a new therapeutic target that in collaboration with PD-1 has the potential to further suppress antitumor immune response. Tislelizumab’s broad combination portfolio in lung cancer also includes PI3K-delta inhibitor BGB-10188, anti-TIM-3 antibody BGB-A425, and chemotherapy.

Growing NSCLC Program Driven by Scientific Excellence and Clinical Insights

To address the prevalence of NSCLC worldwide and the clinical unmet need despite treatment progress in recent years, BeiGene is currently evaluating tislelizumab in a comprehensive NSCLC program of more than 10 clinical trials covering disease settings from early to late lines.

To gain key insights into how different patient characteristics can impact treatment outcomes, BeiGene’s immuno-oncology team reviews clinical results from NSCLC trials by geography, disease stage, smoking status, and using biomarkers.

Subgroup analyses on BeiGene’s RATIONALE 307 trial recently presented at the 2021 World Conference on Lung Cancer (WCLC) showed that tislelizumab in combination with chemotherapy provided consistent survival benefits in treatment-naïve patients with squamous NSCLC, regardless of PD-L1 expression, blood tumor mutation burden (TMB), tissue TMB, and disease stage (IIIB or IV).

At the ESMO Congress 2021, additional analyses on smokers vs. nonsmokers in the two Phase 3 clinical trials in first-line NSCLC, RATIONALE 304 and RATIONALE 307 will be reported.

In addition, the Company is exploring tislelizumab’s potential as an early treatment option, with an ongoing global Phase 3 trial RATIONALE 315 in neoadjuvant or adjuvant settings.

BeiGene Oncology

BeiGene is committed to advancing best and first-in-class clinical candidates internally or with like-minded partners to develop impactful and affordable medicines for patients across the globe. We have a growing R&D team of approximately 2,300 colleagues dedicated to advancing more than 90 clinical trials involving more than 13,000 patients and healthy volunteers. Our expansive portfolio is directed by a predominantly internalized clinical development team supporting trials in more than 40 countries. Hematology-oncology and solid tumor targeted therapies and immuno-oncology are key focus areas for the Company, with both mono- and combination therapies prioritized in our research and development. We currently market three medicines discovered and developed in our labs: BTK inhibitor BRUKINSA in the United States, China, Canada, and additional international markets; and non-FC-gamma receptor binding anti-PD-1 antibody tislelizumab and PARP inhibitor pamiparib in China.

BeiGene also partners with innovative companies who share our goal of developing therapies to address global health needs. We commercialize a range of oncology medicines in China licensed from Amgen and Bristol Myers Squibb. We also plan to address greater areas of unmet need globally through our collaborations including with Amgen, Bio-Thera, EUSA Pharma, Mirati Therapeutics, Seagen, and Zymeworks. BeiGene has also entered into a collaboration with Novartis granting Novartis rights to develop, manufacture, and commercialize tislelizumab in North America, Europe, and Japan.
