IMpower133 is the first Phase III study with an immunotherapy-based combination to show improvement in overall survival and progression-free survival in the initial treatment of extensive-stage small cell lung cancer (ES-SCLC)
There has been limited treatment progress for people with ES-SCLC in the past 20 years
Data will be submitted to health authorities globally, including the U.S. Food and Drug Administration (FDA) and European Medicines Agency (EMA)
South San Francisco, CA -- June 24, 2018 --
Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), today announced that the Phase III IMpower133 study met its co-primary endpoints of overall survival (OS) and progression-free survival (PFS) at its first interim analysis. The study demonstrated that initial (first-line) treatment with the combination of TECENTRIQ® (atezolizumab) plus chemotherapy (carboplatin and etoposide) helped people with extensive-stage small cell lung cancer (ES-SCLC) live significantly longer compared to chemotherapy alone. The TECENTRIQ-based combination also reduced the risk of disease worsening or death (PFS) compared to chemotherapy alone. 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.
“These are the first positive Phase III survival results for any immunotherapy-based combination in the initial treatment of extensive-stage small cell lung cancer, a particularly difficult-to-treat type of disease,” said Sandra Horning, M.D., chief medical officer and head of Global Product Development. “The clinically meaningful results from the IMpower133 study add to the growing body of evidence demonstrating that TECENTRIQ-based combinations may be an effective treatment for different types of advanced lung cancer. We look forward to working with health authorities globally to bring this potential treatment option to people with this type of disease as soon as possible.”
This is the fourth positive Phase III lung cancer study evaluating a TECENTRIQ-based combination to read out this year and the fifth positive study overall. Currently, Genentech has eight Phase III lung cancer studies underway evaluating TECENTRIQ alone or in combination with other medicines across different types of lung cancer.
About the IMpower133 study
IMpower133 is a Phase III, multicenter, double-blinded, randomized placebo-controlled study evaluating the efficacy and safety of TECENTRIQ in combination with carboplatin and etoposide versus chemotherapy (carboplatin plus etoposide) alone in chemotherapy-naïve people with ES-SCLC. The study enrolled 403 people who were randomized equally (1:1) to receive:
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 Tumors Version 1.1 (RECIST v1.1). Treatment could be continued until persistent radiographic PD or symptomatic deterioration was observed.
The co-primary endpoints were:
IMpower133 met its OS and PFS co-primary endpoints as per the study protocol.
About lung cancer
According to the American Cancer Society, it is estimated that more than 234,000 Americans will be diagnosed with lung cancer in 2018, and SCLC accounts for approximately 15 percent of all lung cancers. It is estimated that approximately 60 percent of lung cancer diagnoses in the United States are made when the disease is in the advanced stages.
About TECENTRIQ® (atezolizumab)
TECENTRIQ is a monoclonal antibody designed to bind with a protein called PD-L1. TECENTRIQ is designed to bind to PD-L1 expressed on tumor cells and tumor-infiltrating immune cells, blocking its interactions with both PD-1 and B7.1 receptors. By inhibiting PD-L1, TECENTRIQ may enable the re-activation of T cells. TECENTRIQ may also affect normal cells.
TECENTRIQ U.S. Indication (pronounced ‘tē-SEN-trik’)
TECENTRIQ is a prescription medicine used to treat:
A type of bladder and urinary tract cancer called urothelial carcinoma.
The approval of TECENTRIQ in these patients is based on a study that measured response rate and duration of response. There is an ongoing study to confirm clinical benefit.
A type of lung cancer called non-small cell lung cancer (NSCLC).
If your tumor has an abnormal EGFR or ALK gene, you should have also tried an FDA-approved therapy for tumors with these abnormal genes, and it did not work or is no longer working.
It is not known if TECENTRIQ is safe and effective in children.
Important Safety Information
What is the most important information about TECENTRIQ?
TECENTRIQ can cause the immune system to attack normal organs and tissues and can affect the way they work. These problems can sometimes become serious or life threatening and can lead to death.
Patients should call or see their healthcare provider right away if they get any symptoms of the following problems or these symptoms get worse.
TECENTRIQ can cause serious side effects, including:
Getting medical treatment right away may help keep these problems from becoming more serious. A healthcare provider may treat patients with corticosteroid or hormone replacement medicines. A healthcare provider may delay or completely stop treatment with TECENTRIQ if patients have severe side effects.
Before receiving TECENTRIQ, patients should tell their healthcare provider about all of their medical conditions, including if they:
Patients should tell their healthcare provider about all the medicines they take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.
The most common side effects of TECENTRIQ in people with urothelial carcinoma include:
The most common side effects of TECENTRIQ in people with non-small cell lung cancer include:
TECENTRIQ may cause fertility problems in females, which may affect the ability to have children. Patients should talk to their healthcare provider if they have concerns about fertility.
These are not all the possible side effects of TECENTRIQ. Patients should ask their healthcare provider or pharmacist for more information. Patients should call their doctor for medical advice about side effects.
