Roche presents new data from multiple Phase III studies of Tecentriq in triple-negative breast cancer at ESMO Virtual Congress 2020

• Data from the Phase III IMpassion031 study demonstrated that Tecentriq in combination with chemotherapy improved pathological complete response for patients with early triple-negative breast cancer (TNBC), when compared to placebo plus chemotherapy
• Final overall survival data from the Phase III IMpassion130 study were consistent with prior interim analyses in patients with metastatic TNBC, whose tumours expressed PD-L1 and who received Tecentriq plus nab-paclitaxel
• Results from the Phase III IMpassion131 study, evaluating Tecentriq in combination with paclitaxel for the treatment of people with metastatic TNBC and whose tumours expressed PD-L1, did not meet its primary endpoint of progression-free survival
  
  

Basel, 19 September 2020 - Roche (SIX: RO, ROG; OTCQX: RHHBY) today announced that it presented the latest results from three Phase III studies from the Tecentriq (atezolizumab) clinical development programme in triple-negative breast cancer (TNBC) at the European Society for Medical Oncology (ESMO) Virtual Congress 2020.

“While we have made great progress in the treatment of many forms of breast cancer, TNBC remains an aggressive and difficult-to-treat disease,” said Levi Garraway, M.D., Ph.D., Roche's Chief Medical Officer and Head of Global Product Development. “We are proud of our work to address challenges and advance scientific understanding of cancer immunotherapy in the context of distinct chemotherapy regimens and in various TNBC treatment settings. Although the IMpassion131 study did not reach its endpoint, we are pleased to bring new treatment options for some TNBC patients, and remain committed to improving the lives of all women with early and advanced stages of this disease.”

Results from the Phase III IMpassion031 study, evaluating Tecentriq in combination with chemotherapy (Abraxane, albumin-bound paclitaxel; nab-paclitaxel; followed by doxorubicin and cyclophosphamide) in comparison to placebo plus chemotherapy (including nab-paclitaxel), demonstrated a statistically significant and clinically meaningful improvement in pathological complete response (pCR) for the treatment of people with early TNBC, regardless of PD-L1 expression. pCR was observed in 57.6% (95% CI: 49.7–65.2) of patients treated with Tecentriq in combination with chemotherapy, an increase of 16.5% from 41.1% (95% CI: 33.6–48.9) in patients treated with placebo plus chemotherapy (one-sided p=0.0044, significance boundary = 0.0184) in the intention-to-treat (ITT) population. The safety profile was consistent with the established profile of the individual drugs and no new safety concerns were identified.
