'Small cell lung cancer is an area of major unmet need in
Lung cancer is the most common cancer and the leading cause of cancer death in China.1 Overall, SCLC accounts for around 15% of all lung cancer cases and, with two-thirds of patients diagnosed at the 'extensive' stage, the prognosis for people with this form of the disease is poor.2 The average five-year survival for people with ES-SCLC is only 2%.3
This approval is based on results from the Phase III IMpower133 study, which showed that Tecentriq in combination with chemotherapy helped people live significantly longer compared with chemotherapy alone (median overall survival [OS]=12.3 versus 10.3 months; HR=0.70, 95% CI: 0.54-0.91; p=0.0069). The combination also significantly reduced the risk of disease worsening or death (progression-free survival [PFS]) compared with chemotherapy alone (median PFS=5.2 versus 4.3 months; hazard ratio [HR]=0.77; 95% CI: 0.62-0.96; p=0.017).4 Follow-up analysis suggests that at 18 months the OS rate was 34% for people receiving the Tecentriq-based treatment versus 21% for people receiving chemotherapy alone. Safety for the Tecentriq and chemotherapy combination appeared consistent with the known safety profile of Tecentriq. The results represent the first clinically meaningful advance in the first-line treatment of ES-SCLC in more than 20 years.

About the IMpower133 study
IMpower133 is a Phase III, multicentre, double-blinded, randomised placebo-controlled study evaluating the efficacy and safety of Tecentriq in combination with chemotherapy (carboplatin and etoposide) versus chemotherapy (carboplatin and etoposide) alone in chemotherapy-naive adults with ES-SCLC. The study enrolled 403 people who were randomised equally (1:1) to receive: Tecentriq in combination with carboplatin and etoposide (Arm A), or Placebo in combination with carboplatin and etoposide (Arm B, control arm During the treatment-induction phase, people received treatment on 21-day cycles for four cycles, followed by maintenance with Tecentriq or placebo until progressive disease (PD), as assessed by the investigator using Response Evaluation Criteria in Solid Tumours version 1.1 (RECIST v1.1). Treatment could be continued until persistent radiographic PD or symptomatic deterioration was observed.
The co-primary endpoints were PFS, as determined by the investigator using RECIST v1.1 and OS in the intention-to-treat (ITT) population.
About SCLC
Lung cancer is the leading cause of cancer death globally.5 Each year 1.76 million people die as a result of the disease; this translates into more than 4,800 deaths worldwide every day.5 Lung cancer can be broadly divided into two major types: non-small cell lung cancer (NSCLC) and SCLC, with SCLC accounting for approximately 15% of all lung cancer cases.2
About Tecentriq
Tecentriq is a monoclonal antibody designed to bind with a protein called PD-L1, which is expressed on tumour cells and tumour-infiltrating immune cells, blocking its interactions with both PD-1 and B7.1 receptors. By inhibiting PD-L1, Tecentriq may enable the activation of T-cells. Tecentriq is a cancer immunotherapy that has the potential to be used as a foundational combination partner with other immunotherapies, targeted medicines and various chemotherapies across a broad range of cancers. The development of Tecentriq and its clinical programme is based on our greater understanding of how the immune system interacts with tumours and how harnessing a person's immune system combats cancer more effectively.
Tecentriq is approved in the US, EU and countries around the world, either alone or in combination with targeted therapies and/or chemotherapies in various forms of non-small cell and small cell lung cancer, certain types of metastatic urothelial cancer, and in PD-L1-positive metastatic triple-negative breast cancer.
