South San Francisco, CA -- December 10, 2017 --
Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), today announced that the Phase III IMmotion151 study met its co-primary endpoint of investigator-assessed progression-free survival (PFS) and demonstrated that the combination of TECENTRIQ® (atezolizumab) and Avastin ® (bevacizumab) provided a statistically significant and clinically meaningful reduction in the risk of disease worsening or death (PFS) in people whose disease expressed the PD-L1 (programmed death-ligand 1; PD-L1 expression ≥1 percent) protein compared with sunitinib for the first-line treatment of people who have advanced or metastatic renal cell carcinoma (mRCC).
Observations of a pre-specified subgroup analysis of the TECENTRIQ and Avastin combination indicated that, in people whose disease expressed PD-L1, a numerical difference favoring TECENTRIQ was seen across all patient risk factor groups (favorable, intermediate and poor) compared to sunitinib; however, due to the study design these data could not be assessed for statistical significance and are descriptive only. Assessment of secondary endpoints is ongoing. Safety for the TECENTRIQ and Avastin combination appeared consistent with the known safety profile of the individual medicines and what was previously reported in the Phase II IMmotion150 study. No new safety signals were identified with the combination.
Results will be presented at an upcoming oncology conference in 2018. Top-line results from the co-primary endpoint of overall survival (OS) are not mature.
“We are encouraged by these results as they add to the emerging body of evidence that supports our rationale for this combination. We believe that the regimen of TECENTRIQ and Avastin may enhance the potential of the immune system in the initial treatment of advanced kidney cancer,” said Sandra Horning, M.D., chief medical officer and head of Global Product Development. “We will discuss these data with health authorities globally and hope to bring this combination forward as a potential new treatment option as soon as possible.’’
IMmotion151 is the second successive positive Phase III study of TECENTRIQ that includes an Avastin combination component as an initial treatment. This follows the positive Phase III non-squamous non-small cell lung cancer (NSCLC) IMpower150 study that showed TECENTRIQ and Avastin plus chemotherapy demonstrated a PFS advantage over Avastin plus chemotherapy.
About the IMmotion151 study
IMmotion151 is a Phase III multicenter, randomized, open-label study to evaluate the efficacy and safety of TECENTRIQ and Avastin versus sunitinib in people with inoperable, locally advanced or metastatic renal cell carcinoma (RCC) who have not received prior systemic active or experimental therapy. It enrolled 915 people globally who were randomized 1:1 to receive TECENTRIQ and Avastin, or sunitinib alone.
People in the TECENTRIQ and Avastin arm received TECENTRIQ at a fixed dose of 1200 milligrams (mg) and Avastin at a dose of 15 milligrams per kilogram (mg/kg) via intravenous (IV) infusion every 3 weeks until loss of clinical benefit or unacceptable toxicity. People in the sunitinib arm received sunitinib 50 mg orally, once daily for 4 weeks followed by 2 weeks rest until loss of clinical benefit or unacceptable toxicity.
The co-primary endpoints were PFS, as determined by the investigator using Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1) in people whose tumors expressed PD-L1 [PD-L1 expression ≥1 percent on immune cells (IC)], and OS in the overall study population (intention-to-treat, ITT). PD-L1 expression was prospectively assessed using an immunohistochemistry (IHC) test (SP142) developed by Roche Tissue Diagnostics.
Stratification factors included the presence or absence of liver metastases; level of IC staining for PD-L1 (≥1 percent vs. < 1 percent) and Memorial Sloan-Kettering Cancer Center (Motzer) risk score. The Motzer prognostic scoring system predicts for OS based upon an individual’s baseline clinical and laboratory characteristics. Depending on the presence of one or several of five variables (risk factors), people are classified in one of the three risk groups: “Favorable” with 0 risk factors, “Intermediate” with 1-2 risk factors and “Poor” with ≥ 3 risk factors.
About renal cell carcinoma
According to the American Cancer Society, more than 63,000 people will be diagnosed with kidney cancer in 2017. Renal cell carcinoma (RCC) accounts for approximately 90 percent of all cases. RCC occurs when abnormal cells develop in the tissue of the kidneys, specifically in the small tubes (also known as tubules) where the blood is filtered. Typically, RCC is a single tumor in one kidney but, in rare cases, there can be multiple tumors, which can occur in one or both kidneys. Despite recent progress in the field of kidney cancer, treatment options for people with the disease remains limited.
About the TECENTRIQ (atezolizumab) and Avastin (bevacizumab) combination
There is a strong scientific rationale to support further investigation of TECENTRIQ plus Avastin in combination. We are investigating this combination in a broad range of cancers, including advanced RCC. Avastin, in addition to its anti-angiogenic effects, may further enhance TECENTRIQ’s ability to restore anti-cancer immunity, by inhibiting VEGF-related immunosuppression, promoting T-cell tumor infiltration and enabling priming and activation of T-cell responses against tumor antigens.
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.
About Avastin® (bevacizumab)
Avastin is a prescription-only medicine that is a solution for intravenous infusion. It is a biologic antibody designed to specifically bind to a protein called vascular endothelial growth factor (VEGF) that plays an important role throughout the lifecycle of the tumor to develop and maintain blood vessels, a process known as angiogenesis. Avastin is designed to interfere with the tumor blood supply by directly binding to the VEGF protein to prevent interactions with receptors on blood vessel cells. The tumor blood supply is thought to be critical to a tumor's ability to grow and spread in the body (metastasize). Avastin is the only currently available treatment for people with mRCC that directly inhibits VEGF.
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.
