Roche 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 population (ITT), 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 at 17:53–18:05 CEST (Abstract LBA14) and were featured in the official ESMO press programme.

Tecentriq was the first cancer immunotherapy approved in advanced bladder cancer. Currently, there are four ongoing Phase III studies evaluating Tecentriq alone and in combination with other medicines in early and advanced bladder cancer. Roche has an extensive development programme for Tecentriq, including multiple ongoing and planned Phase III studies, across lung, genitourinary, skin, breast, gastrointestinal, gynaecological, and head and neck cancers. This includes studies evaluating Tecentriq both alone and in combination with other medicines.
