Pivotal Phase III Study Shows Genentech’s Tecentriq Helped People With Early Lung Cancer Live Longer Without Their Disease Returning

SOUTH SAN FRANCISCO, Calif.–()–Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), today announced that the Phase III IMpower010 study evaluating Tecentriq® (atezolizumab), compared with best supportive care (BSC), met its primary endpoint of disease-free survival (DFS) at the interim analysis. Tecentriq showed a statistically significant improvement in DFS as adjuvant therapy following surgery and chemotherapy in all randomized Stage II-IIIA populations with non-small cell lung cancer (NSCLC). The magnitude of DFS benefit was particularly pronounced in the PD-L1-positive population.

Follow-up will continue with planned analyses of DFS in the overall intent-to-treat (ITT) population, which at the time of analysis did not cross the threshold, and overall survival (OS) data, which were immature at the time of interim analysis. Safety for Tecentriq was consistent with its known safety profile and no new safety signals were identified. Results from the IMpower010 study will be presented at an upcoming medical meeting and submitted to health authorities globally, including the U.S. Food and Drug Administration and the European Medicines Agency.

“With these landmark results, Tecentriq has become the first cancer immunotherapy to help many people with resectable early lung cancer live longer without their cancer returning,” said Levi Garraway, M.D., Ph.D., chief medical officer and head of Global Product Development. “We’re excited by the clinical benefit adjuvant Tecentriq may bring to lung cancer patients, particularly in the PD-L1-positive population. We will submit these data to regulatory authorities as soon as possible.”

Tecentriq has previously shown clinically meaningful benefit in various types of lung cancer, with five currently approved indications in the U.S. 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), and also has four approved indications in 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 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 at most 16 cycles of Tecentriq or BSC. The primary endpoint is investigator-determined DFS in the PD-L1-positive Stage II-IIIA, all randomized Stage II-IIIA and ITT Stage IB-IIIA populations. Key secondary endpoints include 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. 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:

    • 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 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:

    • is a type called “extensive-stage small cell lung cancer,” which means that it has spread or grown

It is not known if Tecentriq is safe and effective in children.
