– IMvigor130 is the first positive Phase III study of a cancer immunotherapy combination in people with previously untreated advanced bladder cancer –
– Tecentriq combination reduced the risk of disease worsening or death (progression-free survival) compared with chemotherapy alone –

SOUTH SAN FRANCISCO, CA, USA I September 30, 2019 I Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), today presented positive results from the Phase III IMvigor130 study evaluating Tecentriq® (atezolizumab) plus platinum-based chemotherapy versus chemotherapy alone for the first-line (initial) treatment of people with previously untreated locally advanced or metastatic urothelial carcinoma (mUC) eligible and ineligible for cisplatin chemotherapy. In the study, Tecentriq plus chemotherapy showed a statistically significant improvement in progression-free survival (PFS) compared with platinum-based chemotherapy alone (median PFS=8.2 versus 6.3 months; hazard ratio [HR]=0.82, 95% CI: 0.70-0.96; p=0.007). Encouraging overall survival (OS) results were observed for Tecentriq plus chemotherapy compared with chemotherapy alone in the intention-to-treat (ITT) population, however these data did not reach statistical significance at this interim analysis (median OS=16.0 versus 13.4 months; HR=0.83, 95% CI: 0.69-1.00). Safety in the Tecentriq plus chemotherapy arm appeared consistent with the known safety profiles of the individual medicines, and no new safety signals were identified with the combination.
“We are pleased with these positive results from the IMvigor130 study, which show Tecentriq plus chemotherapy may provide a meaningful benefit for people newly diagnosed with advanced bladder cancer,” said Sandra Horning, M.D., chief medical officer and head of Global Product Development. “There remains a high unmet need for people with advanced bladder cancer, where chemotherapy alone is the current standard of care. These results reinforce the role of immunotherapy in treating this aggressive disease.”
Additional data from the Tecentriq monotherapy arm were also presented in the ITT population and people with different levels of PD-L1 expression. Encouraging OS results were observed with Tecentriq monotherapy in people with high PD-L1 expression (IC2/3), however these data were not formally tested per the hierarchical design of the trial. Follow-up will continue until the next analysis.
These data will be presented today at the European Society for Medical Oncology (ESMO) 2019 Congress Presidential Symposium from 5:53 – 6:05 p.m. CEST (Abstract LBA14) and were featured in the official ESMO press program.
Tecentriq was the first cancer immunotherapy approved in advanced bladder cancer. Tecentriq has accelerated approval from the U.S. Food and Drug Administration (FDA) for the treatment of adults with locally advanced or mUC, including those who are not eligible for cisplatin-containing chemotherapy and whose tumors express high levels of PD-L1 (PD-L1–stained tumor-infiltrating immune cells covering ≥5% of the tumor area) as determined by an FDA-approved test or are not eligible for any platinum-containing chemotherapy regardless of PD-L1 status. The accelerated approval also includes the treatment of adults with locally advanced or mUC whose disease had progressed during or following platinum-containing chemotherapy, or within 12 months of receiving chemotherapy before surgery (neoadjuvant) or after surgery (adjuvant). These accelerated approvals are based on tumor response rate and durability of response. Continued approval in these types of bladder cancer may be contingent upon verification and description of clinical benefit in a confirmatory trial.
Currently, there are four ongoing Phase III studies evaluating Tecentriq alone and in combination with other medicines in early and advanced bladder cancer. Genentech has an extensive development program for Tecentriq, including multiple ongoing and planned Phase III studies, across lung, genitourinary, skin, breast, gastrointestinal, gynecological and head and neck cancers. This includes studies evaluating Tecentriq both alone and in combination with other medicines.
About the IMvigor130 study
IMvigor130 is a multicenter, partially blinded, randomized Phase III study, evaluating the efficacy and safety of Tecentriq in combination with chemotherapy or alone versus chemotherapy alone for people with mUC who have not received prior systemic therapy for metastatic disease. It enrolled 1,213 people who received:
- Tecentriq plus platinum-based chemotherapy (gemcitabine with either cisplatin or carboplatin), or
- Tecentriq, or
- Platinum-based chemotherapy (gemcitabine with either cisplatin or carboplatin) plus placebo (control arm).
In the Tecentriq combination arm, the co-primary endpoints are OS and PFS as assessed by investigator using Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1). The secondary endpoints are objective response rate and duration of response, as assessed by investigator using RECIST v1.1, and independent review facility-assessed PFS.
A summary of the key study results is included below:
Tecentriq + platinum-based chemotherapy
Placebo + platinum-based chemotherapy
|PFS (co-primary endpoint)|
Median PFS (months)
|HR (95% CI)||0.82 (0.70, 0.96)|
|OS (co-primary endpoint)|
|Median OS (months)||16.0||13.4|
|(95% CI)||(13.9, 18.9)||(12.0, 15.2)|
|HR (95% CI)||0.83 (0.69, 1.00)*|
|ORR (secondary endpoint)|
|Responders (%)||212 (47.4%)||174 (43.8%)|
|95% CI||(42.7%, 52.2%)||(38.9%, 48.9%)|
|Complete response %||56 (12.5%)||27 (6.8%)|
|*The OS result did not cross the pre-specified efficacy boundary for statistical significance. Follow-up will continue until the next interim analysis.|
Safety for the Tecentriq plus chemotherapy combination appeared consistent with the known safety profile of the individual medicines, and no new safety signals were identified with the combination. There appeared to be no worsening of tolerability with the addition of Tecentriq to chemotherapy compared with chemotherapy alone. All cause Grade 3-4 adverse events (AEs) were reported in 85% of people receiving Tecentriq plus chemotherapy compared with 86% of people receiving chemotherapy alone. Treatment-related Grade 3-4 AEs were reported in 83% of people receiving Tecentriq plus chemotherapy compared with 81% of people receiving chemotherapy alone. Any grade AEs leading to any treatment discontinuation of Tecentriq or placebo were observed in 11% and 7% of people in the combination arm compared with the chemotherapy arm respectively.
About bladder cancer
According to the American Cancer Society (ACS), it is estimated that more than 80,000 Americans will be diagnosed with bladder cancer in 2019, and about 11% of new diagnoses are made when bladder cancer is in advanced stages. There is a dramatic difference in survival rates between early and advanced bladder cancer. The ACS estimates that approximately 90% of people will live five or more years when diagnosed with the earliest stage of the disease, compared to 40% 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 re-activation of T cells. Tecentriq may also affect normal cells.
Tecentriq U.S. Indications
Tecentriq is a prescription medicine used to treat adults with:
A type of bladder and urinary tract cancer called urothelial carcinoma. Tecentriq may be used when your bladder cancer:
- has spread or cannot be removed by surgery, and if you have any one of the following conditions:
- you are not able to take chemotherapy that contains a medicine called cisplatin, and your doctor has tested your cancer and found high levels of a specific protein on your cancer called programmed death-ligand 1 (PD-L1), or
- you are not able to take chemotherapy that contains any platinum regardless of the levels of “PD-L1” status, or
- you have tried chemotherapy that contains platinum, and it did not work or is no longer working
The approval of Tecentriq in these patients is based on a study that measured response rate and duration of response. Continued approval for this use may depend on the results of an ongoing study to confirm benefit.
It is not known if Tecentriq is safe and effective in children.
