New Phase III Data Support the Benefit of Genentech’s Tecentriq in Early-stage Lung Cancer

– Data presented at the 2021 ESMO Virtual Congress and the IASLC 2021 WCLC add to the body of evidence supporting Tecentriq’s role in treating early-stage lung cancer –

– As published in The Lancet, Tecentriq is the first and only cancer immunotherapy to demonstrate positive Phase III results in the adjuvant lung cancer setting –

– Tecentriq was granted Priority Review by the FDA and is currently being reviewed under the Real-Time Oncology Review pilot program –

Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), today presented new data from the Phase III IMpower010 study at the European Society for Medical Oncology (ESMO) Congress 2021 Presidential Symposium, reinforcing the significant disease-free survival (DFS) benefit offered by Tecentriq^® (atezolizumab) for people with Stage II-IIIA non-small cell lung cancer (NSCLC) whose tumors express PD-L1≥1%. Data from the IMpower010 trial were published simultaneously in The Lancet. In IMpower010, treatment with Tecentriq, following surgery and chemotherapy, reduced the risk of disease recurrence or death (DFS) by 34% (hazard ratio [HR]=0.66, 95% CI: 0.50–0.88) in people with Stage II-IIIA NSCLC whose tumors express PD-L1≥1%, compared with best supportive care (BSC). Safety data for Tecentriq were consistent with its known safety profile and no new safety signals were identified.

“Today more than half of all people with early-stage NSCLC experience recurrence following surgery,” said Levi Garraway, M.D., Ph.D., chief medical officer and head of Global Product Development. “IMpower010 shows how, for the first time, a cancer immunotherapy may help many of these patients live longer without their disease returning. The data presented at ESMO and WCLC further contribute to our understanding of Tecentriq in this treatment setting.”

At the 2021 ESMO Virtual Congress, new real-world data show that almost three-quarters of patients with early-stage NSCLC in the U.S. did not receive adjuvant treatment, despite guideline recommendations. Data presented from IMpower010 show that adjuvant Tecentriq offers a DFS benefit in the Stage II-IIIA patient population, irrespective of the stage of disease and across the main prior therapies. Specifically, time to relapse appeared to be improved with Tecentriq, compared with BSC, among people with Stage II-IIIA NSCLC whose tumors express PD-L1 TC ≥1%, for both locoregional and distant sites. There was no clear difference in patterns of relapse. An extended analysis of PD-L1 subgroups in the Stage II-IIIA population shows there is a higher magnitude of benefit from adjuvant Tecentriq in people with PD-L1 expression ≥50%, compared with those with 1-49% PD-L1 expression. The exploratory nature of the analysis in patients with 1-49% PD-L1 expression prevents any firm conclusions, and these data will be further analyzed and shared at a future medical congress.

Additional IMpower010 data, recently presented at the International Association for the Study of Lung Cancer (IASLC) 2021 World Conference on Lung Cancer (WCLC) Presidential Symposium, showed that treatment with Tecentriq improved DFS in the PD-L1≥1% Stage II-IIIA NSCLC population, compared with BSC, regardless of most surgery types and adjuvant chemotherapy regimens.

Based on the IMpower010 data, the U.S. Food and Drug Administration (FDA) recently granted Priority Review to Tecentriq as an adjuvant treatment for certain people with early NSCLC and is reviewing the application under the Real-Time Oncology Review pilot program, which aims to explore a more efficient review process to ensure safe and effective treatments are available to patients as early as possible. The FDA is expected to make a decision on approval by December 1, 2021.

Tecentriq has previously shown clinically meaningful benefit in various types of lung cancer, with five currently approved indications in markets around the world. It was the first approved cancer immunotherapy for front-line treatment of adults with extensive-stage small cell lung cancer (SCLC) in combination with carboplatin and etoposide (chemotherapy). Tecentriq also has four approved indications in advanced NSCLC as either a single agent or in combination with targeted therapies and/or chemotherapies. Tecentriq is available in three dosing options, providing the flexibility to choose administration every two, three or four weeks.

Genentech has an extensive development program for Tecentriq, including multiple ongoing and planned Phase III studies across different settings in lung, genitourinary, skin, breast, gastrointestinal, gynecological, and head and neck cancers. This includes studies evaluating Tecentriq both alone and in combination with other medicines, as well as studies in metastatic, adjuvant and neoadjuvant settings across various tumor types.

About the IMpower010 study

IMpower010 is a Phase III, global, multicenter, open-label, randomized study evaluating the efficacy and safety of Tecentriq compared with BSC, in participants with Stage IB-IIIA NSCLC (UICC 7th edition), following surgical resection and up to 4 cycles of adjuvant cisplatin-based chemotherapy. The study randomized 1,005 people with a ratio of 1:1 to receive either Tecentriq (up to 16 cycles) or BSC. The primary endpoint is investigator-determined DFS in the PD-L1-positive Stage II-IIIA, all randomized Stage II-IIIA and intent-to-treat (ITT) Stage IB-IIIA populations. Key secondary endpoints include overall survival (OS) in the overall study population, ITT Stage IB-IIIA NSCLC.

About lung cancer

According to the American Cancer Society, it is estimated that more than 235,000 Americans will be diagnosed with lung cancer in 2021, and NSCLC accounts for 80-85% of all lung cancers. Today, about half of all people with early lung cancer still experience a cancer recurrence following surgery, but treating lung cancer early, before it has spread, may help prevent the disease from returning and provide people with the best opportunity for a cure.

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 lung cancer called non-small cell lung cancer (NSCLC).

• Tecentriq may be used alone as their first treatment when their lung cancer:
  • has spread or grown, and
  • their cancer tests positive for “high PD-L1”, and
  • their tumor does not have an abnormal “EGFR” or “ALK” gene
• Tecentriq may be used with the medicines bevacizumab, paclitaxel, and carboplatin as their first treatment when their lung cancer:
  • has spread or grown, and
  • is a type called “non-squamous NSCLC,” and
  • their tumor does not have an abnormal “EGFR” or “ALK” gene
• Tecentriq may be used with the medicines paclitaxel protein-bound and carboplatin as their first treatment when their lung cancer:

  • their tumor does not have an abnormal “EGFR” or “ALK” gene
• Tecentriq may also be used when their lung cancer:
  • has spread or grown, and
  • they have tried chemotherapy that contains platinum, and it did not work or is no longer working
  • if their tumor has an abnormal “EGFR” or “ALK” gene, they should have also tried an FDA-approved therapy for tumors with these abnormal genes, and it did not work or is no longer working

A type of lung cancer called small cell lung cancer (SCLC).

• Tecentriq may be used with the chemotherapy medicines carboplatin and etoposide as their first treatment when their lung cancer:
