FDA Grants Genentech’s Tecentriq (atezolizumab) Accelerated Approval as Initial Treatment for Certain People with Advanced Bladder Cancer
South San Francisco, CA -- April 17, 2017 -- Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), today announced that the U.S. Food and Drug Administration (FDA) granted accelerated approval to Tecentriq (atezolizumab) for the treatment of people with locally advanced or metastatic urothelial carcinoma (mUC) who are not eligible for cisplatin chemotherapy. Tecentriq was previously approved for people with locally advanced or mUC who have disease progression during or following any platinum-containing chemotherapy, or within 12 months of receiving chemotherapy before surgery (neoadjuvant) or after surgery (adjuvant). It is not known if Tecentriq is safe and effective in children. Bladder cancer is the most common type of urothelial carcinoma, and up to half of all people with the advanced form of the disease are unable to receive cisplatin chemotherapy as an initial treatment and therefore have a high unmet medical need. Urothelial carcinoma also includes cancers of the urethra, ureters and renal pelvis.
“We are pleased that Tecentriq will now be available to more people with advanced bladder cancer, including those who are unable to receive initial treatment with cisplatin chemotherapy,” said Sandra Horning, M.D., chief medical officer and head of Global Product Development. “Tecentriq was the first cancer immunotherapy approved by the FDA for people with advanced bladder cancer and has become a standard of care in those whose disease has progressed after receiving other medicines, either before or after surgery, or after their disease has spread.”
“It is encouraging to see continued progress in the treatment of advanced bladder cancer, which until last year had not seen any major advancements in more than 30 years,” said Andrea Maddox Smith, chief executive officer, Bladder Cancer Advocacy Network. “We are excited that Tecentriq is now a treatment option for people with advanced bladder cancer who are unable to receive a cisplatin-based chemotherapy as an initial treatment.”
The FDA’s Accelerated Approval Program allows conditional approval of a medicine that fills an unmet medical need for a serious condition, based on early evidence suggesting clinical benefit. The indication for Tecentriq is approved under accelerated approval based on tumor response rate and duration of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trials. Today’s approval of Tecentriq is based on the Phase II IMvigor210 study.
Possible serious side effects with Tecentriq include, but are not limited to, lung problems (pneumonitis), liver problems (hepatitis), intestinal problems (colitis), hormone gland problems (especially the pituitary, thyroid, adrenal glands and pancreas), nervous system problems (neuropathy, meningitis and encephalitis), eye problems (inflammation of the eyes), severe infections and severe infusion reactions. Additional information on these and other side effects can be found below.
For those who qualify, Genentech offers patient assistance programs for people taking Tecentriq through Genentech Access Solutions. Doctors can contact Genentech Access Solutions at (888) 249-4918. More information is also available at http://www.Genentech-Access.com.
This is the third approval for Tecentriq in under a year. Tecentriq is also approved for the treatment of people with metastatic non-small cell lung cancer (NSCLC) who have disease progression during or following platinum-containing chemotherapy, and have progressed on an appropriate FDA-approved targeted therapy if their tumor has EGFR or ALK gene abnormalities.
About the IMvigor210 Study
IMvigor210 is an open-label, multicenter, single-arm Phase II study that evaluated the safety and efficacy of Tecentriq in people with locally advanced or mUC, regardless of PD-L1 expression. People in the study were enrolled into one of two cohorts. This accelerated approval is based on results from Cohort 1, which consisted of 119 people with locally advanced or mUC who were ineligible for cisplatin-containing chemotherapy and were either previously untreated or had disease progression at least 12 months after neoadjuvant or adjuvant chemotherapy. People in this cohort received a 1200-mg intravenous dose of Tecentriq every three weeks until either unacceptable toxicity or disease progression. The primary endpoint of the study was objective response rate (ORR).
A summary of the efficacy data from the IMvigor210 study that supports this accelerated approval is included below.

The most common Grade 3-4 adverse reactions (≥ 2 percent) were: fatigue (8 percent), urinary tract infection (5 percent), anemia (7 percent), diarrhea (5 percent), increase in the level of creatinine in the blood (5 percent), intestinal obstruction (partial or complete blockage of the bowel), increase of the liver enzyme alanine transaminase (4 percent), hyponatremia (low blood sodium level; 15 percent), decreased appetite (3 percent), sepsis (blood infection), back/neck pain (3 percent), renal failure and hypotension (low blood pressure). Five people (4.2 percent) experienced either sepsis, cardiac arrest, myocardial infarction, respiratory failure or respiratory distress, which led to death. One additional patient (0.8 percent) experienced inflammation of the brain due to the herpes simplex virus(herpetic meningoencephalitis) and disease progression at the time of death. Tecentriq was discontinued for adverse reactions in 4.2 percent (5) of the 119 patients.
Genentech is evaluating Tecentriq in a confirmatory Phase III study (IMvigor211), which compares Tecentriq to chemotherapy as initial treatment in people with a specific type of advanced bladder cancer and in people whose bladder cancer has progressed on at least one prior platinum-containing regimen.
About Metastatic Urothelial Cancer
According to the American Cancer Society (ACS), it is estimated that more than 79,000 Americans will be diagnosed in 2017 with bladder cancer, which is the most common type of urothelial cancer. Less common forms include cancers of the urethra, ureters and renal pelvis. About 11 percent of new diagnoses of bladder cancer are made when the disease is in advanced stages. There is a dramatic difference in survival rates between early and advanced bladder cancer. Approximately 96 percent of people will live five or more years when diagnosed with the earliest stage of the disease, compared to 39 percent when diagnosed in advanced stages (stage III-IV) of the disease. Men are about three to four times more likely to get bladder cancer during their lifetime than women.

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 activation of T cells. Tecentriq may also affect normal cells.
