China National Medical Products Administration grants approval of Roche’s Tecentriq in combination with chemotherapy as first-line treatment of people with extensive-stage small cell lung cancer - Seite 2

In January 2020, the China NMPA also accepted the supplemental Biologics License Application (sBLA) for Tecentriq in combination with Avastin (bevacizumab) for the treatment of people with unresectable hepatocellular carcinoma (HCC), the most common form of liver cancer, who have not received prior systemic therapy. The submission is based on the results from the Phase III IMbrave150 study, which met both of its co-primary endpoints, demonstrating statistically significant and clinically meaningful improvements in OS and PFS compared with current standard of care, sorafenib.

Roche has an extensive development programme for Tecentriq, including multiple ongoing and planned Phase III studies, across lung, genitourinary, skin, breast, gastrointestinal, gynaecological, and head and neck cancers. This includes studies evaluating Tecentriq both alone and in combination with other medicines.

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-naïve 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.

A summary of the ITT data from the IMpower133 study that support this approval is included below:¹

• Tecentriq in combination with chemotherapy helped people live significantly longer, compared with chemotherapy alone (OS=12.3 versus 10.3 months; HR=0.70, 95% CI: 0.54–0.91, p=0.0069) in the ITT population.
• The Tecentriq-based combination also significantly reduced the risk of disease worsening or death compared with chemotherapy alone (median PFS=5.2 versus 4.3 months; HR=0.77; 95% CI: 0.62–0.96, p=0.017).
• Safety for the Tecentriq and chemotherapy combination appeared consistent with the known safety profile of Tecentriq.
• Grade 3–4 treatment-related adverse events occurred in 56.6% of people receiving Tecentriq plus chemotherapy, compared with 56.1% of people receiving chemotherapy alone. The most common adverse reactions (≥10%) in people receiving Tecentriq plus chemotherapy were low white blood cell count (neutropenia; 23%), anaemia (14%), decreased neutrophil count (14%) and thrombocytopenia (10%).
