Tislelizumab is approved for the first-line treatment of advanced non-squamous non-small cell lung cancer following the previously approved squamous histology

Tislelizumab receives its first approval in liver cancer in previously treated hepatocellular carcinoma

CAMBRIDGE, Mass. & BEIJING--(BUSINESS WIRE)-- BeiGene, Ltd. (NASDAQ: BGNE; HKEX: 06160), a global biotechnology company focused on developing and commercializing innovative medicines worldwide, today announced that the China National Medical Products Administration (NMPA) has granted its anti-PD-1 antibody tislelizumab approval for the first-line treatment of patients with advanced non-squamous non-small cell lung cancer (NSCLC) and conditional approval for the treatment of patients with hepatocellular carcinoma (HCC) who have been previously treated with at least one systemic therapy.

“With today’s approvals, tislelizumab is now available in China in five indications covering lung, liver, bladder, and lymphoma, and is becoming an important immunotherapy in the world’s most populous country,” commented Xiaobin Wu, Ph.D., President, Chief Operating Officer, and General Manager of China at BeiGene. “This remarkable achievement, which began approximately 18 months ago with tislelizumab’s initial approval, was made possible through BeiGene’s integrated global clinical development approach. We hope to make tislelizumab available broadly in China through our science-based commercial team and globally through our collaboration with Novartis, in furtherance of our goal of expanding access to innovative, quality cancer treatments for more people worldwide.”

“We are pleased about the concurrent approvals for tislelizumab in China – in first-line non-squamous NSCLC following the previous approval for NSCLC patients with squamous histology earlier this year, and in second- or third-line HCC, which was based on the results from the largest global single-arm pivotal trial of any anti-PD-1 antibody in this indication,” said Yong (Ben) Ben, M.D., Chief Medical Officer, Immuno-Oncology at BeiGene. “The pivotal clinical program of tislelizumab has seen tremendous progress lately, including two positive Phase 3 trials, one in esophageal cancer and the other in nasopharyngeal cancer. We credit our accomplishment to the dedication of our BeiGene team, and most importantly, the trust from participating patients and their loved ones, as well as investigators leading these clinical trials.”

NMPA Approval in First-Line Advanced Non-Squamous NSCLC

“NSCLC comprises the most common form of lung cancer, although diagnoses are usually delayed with most patients diagnosed at advanced stage. In the Phase 3 RATIONALE 304 trial, tislelizumab in combination with pemetrexed and platinum chemotherapy demonstrated a clinically significant improvement in progression-free survival along with a high response rate, and was generally well-tolerated for treatment-naïve patients with advanced non-squamous NSCLC,” commented Shun Lu, M.D., Ph.D., Professor of Shanghai Chest Hospital at Jiao Tong University and lead investigator for the trial. “I believe that this approval could help meet the significant demand in the front-line care of NSCLC, and I also look forward to the overall survival data readout.”

The approval of tislelizumab for the first-line treatment of patients with advanced non-squamous NSCLC was supported by clinical results from a Phase 3 trial (NCT03663205) of tislelizumab in combination with pemetrexed and platinum chemotherapy (either carboplatin or cisplatin) in patients with stage IIIB or stage IV non-squamous NSCLC, compared to pemetrexed and platinum alone. A total of 334 patients in China were enrolled in the trial, randomized 2:1 to either the tislelizumab and chemotherapy arm or the chemotherapy arm. As announced in April 2020, the trial met the primary endpoint of statistically significant improvement in progression-free survival (PFS), as assessed by independent review committee (IRC), in the pre-planned interim analysis. The safety profile of tislelizumab in combination with chemotherapy was consistent with the known risks of each study treatment, and no new safety signals were identified. The results of the interim analysis of the trial were presented at the European Society for Medical Oncology (ESMO) Virtual Congress 2020 in September 2020.

NMPA Approval in Second- or Third-Line HCC

The NMPA conditional approval of tislelizumab in patients with HCC who have received at least one systemic therapy is based on clinical results from a single-arm, open-label, multicenter, global pivotal Phase 2 trial (NCT03419897) conducted in 249 patients from eight countries and regions in Asia and Europe, including 138 patients (55.4%) who received one line of prior systemic therapy and 111 patients (44.6%) who received at least two lines of prior therapies. Of all the patients enrolled in the trial, the median age was 62 years and 63.9% of patients had history of viral hepatitis, with hepatitis B accounting for the majority (51.4%) followed by hepatitis C (14.5%).

“Hepatocellular carcinoma is a difficult-to-treat primary liver cancer, most commonly found in those living with chronic liver diseases, such as hepatitis B and C. Based on the encouraging efficacy and safety results in patients with advanced liver cancer from this trial, tislelizumab has the potential to bring long-term survival benefits to patients with second- or third-line HCC in China,” commented Zhenggang Ren, M.D., Ph.D., Professor at Zhongshan Hospital, Fudan University, and the trial’s leading investigator in China.

With a median follow-up time of 12.4 months, objective response rate (ORR) as assessed by IRC per RECIST v1.1 was 13.3% (95% CI: 9.3, 18.1), including three complete responses (CRs); disease control rate (DCR) was 53.0% (95% CI: 46.6, 59.3); among patients who achieved a CR or partial response (PR), 90.4% (95% CI: 73.1, 96.8) and 79.2% (95% CI: 59.3, 90.2) of them sustained response at six months and 12 months, respectively. Median overall survival (OS) was 13.2 months (95% CI: 10.8, 15.0) and PFS was 2.7 months (95% CI: 1.4, 2.8).

The safety profile of tislelizumab as a monotherapy in the label in China was based on 1,183 patients who received tislelizumab as a monotherapy in five clinical trials, including the pivotal Phase 2 trial in HCC. The most common adverse reactions (≥10%) were aspartate aminotransferase (AST) increased, alanine aminotransferase (ALT) increased, rash, and fatigue. Grade ≥3 adverse reactions occurred in 17.3% of patients, with the most common (≥1%) being AST increased, ALT increased, gamma-glutamyltransferase increased, anemia, pneumonitis, and lung infection. For tislelizumab as a monotherapy, the most common immune-mediated adverse reactions were immune-mediated pneumonitis, diarrhea and colitis, hepatitis, nephritis, endocrinopathies (hypothyroidism, hyperthyroidism, thyroiditis, adrenocortical insufficiency, and hyperglycemia and Type 1 diabetes mellitus), skin adverse reactions, pancreatitis, myocarditis, and myositis.

About Non-Small Cell Lung Cancer

Lung cancer is the second most common type of cancer and the leading cause of cancer-related death worldwide.i NSCLC accounts for approximately 85% of all lung cancer cases and is usually diagnosed at an advanced stage.ii For patients with advanced NSCLC that has metastasized to distant regions or organs in the body, the relative five-year survival rate is approximately 6%.iii In 2020, there were an estimate of 815,563 new cases of lung cancer in China, accounting for 37% of all incidences worldwide.iv

About Hepatocellular Carcinoma

HCC is a major global health problem, accounting for 85-90 percent of all reported cases of liver cancer.v Liver cancer is the sixth most common type of cancer, with an estimated 905,677 new cases in 2020 worldwide; it was also the third most common cause of cancer-related mortality, responsible for an estimated 830,180 deaths in 2020.i China accounts for approximately 50 percent of both new HCC cases and HCC-related deaths worldwide in 2020.iv

About Tislelizumab

Tislelizumab (BGB-A317) is a humanized IgG4 anti-PD-1 monoclonal antibody specifically designed to minimize binding to FcγR on macrophages. In pre-clinical studies, binding to FcγR on macrophages has been shown to compromise the anti-tumor activity of PD-1 antibodies through activation of antibody-dependent macrophage-mediated killing of T effector cells. Tislelizumab is the first drug from BeiGene’s immuno-oncology biologics program and is being developed internationally as a monotherapy and in combination with other therapies for the treatment of a broad array of both solid tumor and hematologic cancers.

The China National Medical Products Administration (NMPA) has granted tislelizumab in five indications, including full approval for first-line treatment of patients with advanced squamous non-small cell lung cancer (NSCLC) in combination with chemotherapy and for first-line treatment of patients with advanced non-squamous NSCLC in combination with chemotherapy; and conditional approval for the treatment of patients with classical Hodgkin’s lymphoma (cHL) who received at least two prior therapies, for the treatment of patients with locally advanced or metastatic urothelial carcinoma (UC) with PD-L1 high expression whose disease progressed during or following platinum-containing chemotherapy or within 12 months of neoadjuvant or adjuvant treatment with platinum-containing chemotherapy, and for the treatment of patients with hepatocellular carcinoma (HCC) who have received at least one systemic therapy. Full approval for these indications is contingent upon results from ongoing randomized, controlled confirmatory clinical trials.

In addition, two supplemental Biologics License Applications for tislelizumab have been accepted by the Center for Drug Evaluation (CDE) of the NMPA and are under review for second- or third-line treatment of patients with locally advanced or metastatic NSCLC who progressed on prior platinum-based chemotherapy and for patients with previously treated, locally advanced unresectable or metastatic microsatellite instability-high (MSI-H) or mismatch repair-deficient (dMMR) solid tumors.

BeiGene has initiated or completed 17 potentially registration-enabling clinical trials in China and globally, including 13 Phase 3 trials and four pivotal Phase 2 trials.

In January 2021, BeiGene and Novartis entered into a collaboration and license agreement granting Novartis rights to develop, manufacture, and commercialize tislelizumab in North America, Europe, and Japan.

Tislelizumab is not approved for use outside of China.
