Roche has announced that the Phase III IMpower132 study met its co-primary endpoint of progression-free survival (PFS). It also demonstrated that the combination of Tecentriq ® (atezolizumab) plus chemotherapy (cisplatin or carboplatin plus pemetrexed) reduced the risk of disease worsening or death (PFS) compared to chemotherapy alone in the initial (first-line) treatment of advanced non-squamous non-small cell lung cancer (NSCLC).
While a numerical improvement for the co-primary endpoint of overall survival (OS) was observed, statistical significance was not met at this interim analysis, and the study will continue as planned with final OS results expected next year. Safety for the Tecentriq and chemotherapy combination appeared consistent with the known safety profile of the individual medicines, and no new safety signals were identified with the combination. These data will be presented at an upcoming medical meeting.
Lung cancer is the leading cause of cancer death globally. Each year 1.59 million people die as a result of the disease; this translates into more than 4,350 deaths worldwide every day. Lung cancer can be broadly divided into two major types: NSCLC and small cell lung cancer. NSCLC is the most prevalent type, accounting for around 85% of all cases. NSCLC comprises non-squamous and squamous-cell lung cancer, the squamous form of which is characterised by flat cells covering the airway surface when viewed under a microscope. The squamous form tends to grow near the centre of the lung, and accounts for approximately 25-30% of all NSCLC cases.
Tecentriq is a monoclonal antibody designed to bind with a protein called PD-L1 expressed on tumour cells and tumour-infiltrating immune cells, blocking its interactions with both PD-1 and B7. receptors. By inhibiting PD-L1, Tecentriq may enable the activation of T cells. Tecentriq has the potential to be used as a foundational combination partner with cancer immunotherapies, targeted medicines and various chemotherapies across a broad range of cancers.
Sandra Horning, MD, Roche’s Chief Medical Officer and Head of Global Product Development said, “The IMpower132 study showed Tecentriq plus chemotherapy prolonged the time people with this type of advanced lung cancer lived without their disease worsening. We will discuss these results with health authorities.”
