Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), today announced the U.S. Food and Drug Administration (FDA) Oncologic Drugs Advisory Committee (ODAC) voted 7 to 2 in favor of maintaining accelerated approval of Tecentriq ^® (atezolizumab) in combination with chemotherapy (Abraxane ^®, albumin-bound paclitaxel; nab-paclitaxel) for the treatment of adults with unresectable locally advanced or metastatic triple-negative breast cancer (mTNBC) whose tumors express PD-L1, as determined by an FDA-approved test. Today’s ODAC meeting is part of an industry-wide review of accelerated approvals with confirmatory trials that have not met their primary endpoint(s) and have yet to gain regular approvals. The advisory committee provides the FDA with independent opinions and recommendations from outside medical experts, though the recommendations are not binding. The FDA has not announced when it will make its final decision for Tecentriq in this indication.

“People with triple-negative breast cancer have few treatment options, which is why today's committee decision to recognize the importance of this Tecentriq combination is significant,” said Levi Garraway, M.D., Ph.D., chief medical officer and head of Global Product Development. “We are grateful to the FDA and ODAC for the open dialogue and look forward to continued collaboration to improve the lives of people with breast cancer.”

The FDA's Accelerated Approval Program allows for conditional approval of a medicine that fills an unmet medical need for a serious condition, with specific postmarketing requirements (PMRs) to confirm the clinical benefit and convert to regular approval.

Tecentriq was granted accelerated approval in March 2019 for the treatment of adults with PD-L1-positive, unresectable locally advanced or mTNBC based on the positive progression-free survival (PFS) results from the IMpassion130 study. Continued approval for this indication was contingent upon the results of IMpassion131, the PMR for the mTNBC indication. This study did not meet its primary endpoint of PFS for the initial (first-line) treatment of people with mTNBC in the PD-L1-positive population. As the clinically meaningful benefit demonstrated in the IMpassion130 study remains, Genentech looks forward to continuing to work with the FDA to determine next steps with regard to Tecentriq in this indication.

Genentech remains committed to following the science to better understand cancer, including which patients may benefit most from immunotherapy treatment. Tecentriq has already demonstrated its transformational role in areas of high medical need and is a first in class medicine approved for particularly difficult to treat cancers. Tecentriq’s extensive development program includes 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.

Tomorrow, on April 28th, the ODAC will discuss Tecentriq’s accelerated approval for the treatment of people with locally advanced or metastatic urothelial carcinoma (mUC, bladder cancer) who are not eligible for cisplatin-containing chemotherapy.

About triple-negative breast cancer

Breast cancer is the most common cancer among women worldwide. According to the American Cancer Society, close to 285,000 people in the United States will be diagnosed with invasive breast cancer, and more than 44,000 will die from the disease in 2021. Breast cancer is not one, but many diseases based on the biology of each tumor. In triple-negative breast cancer, tumor cells lack hormone receptors and do not have excess HER2 protein. Approximately 15 percent of breast cancers are triple-negative based on the results of diagnostic tests. It is an aggressive form of the disease with few treatment options.

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 in patients with urothelial carcinoma if their bladder cancer has spread or cannot be removed by surgery, and if they have any one of the following conditions:

• They are not able to take chemotherapy that contains a medicine called cisplatin and their cancer tests positive for “PD-L1”, or
• They are not able to take chemotherapy that contains any platinum regardless of the levels of “PD-L1” status

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.

A type of lung cancer called non-small cell lung cancer (NSCLC).

Tecentriq may be used alone as the first treatment in patients with lung cancer if:

• Their 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 the first treatment in patients with lung cancer if:

• Their cancer has spread or grown, and
• Is a type of lung cancer 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 the first treatment in patients with lung cancer if:

• Their cancer has spread or grown, and
• Is a type of lung cancer called “non-squamous NSCLC”, and
• Their tumor does not have an abnormal “EGFR” or “ALK” gene.

Tecentriq may be used alone in patients with lung cancer if:

• Their cancer has spread or grown, and
• They have tried chemotherapy that contains platinum, and it did not work or is no longer working.
• If a patient’s 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 breast cancer called triple-negative breast cancer (TNBC).

Tecentriq may be used with the medicine paclitaxel protein-bound in patients with TNBC when their breast cancer:

• Has spread or cannot be removed by surgery, and
• Their cancer tests positive for “PD-L1”.

The approval of Tecentriq in these patients is based on a study that measured the amount of time until patients’ disease worsened. Continued approval for this use may depend on the results of an ongoing study to confirm benefit.

Tecentriq is not for use with the medicine paclitaxel (a different medicine than paclitaxel protein-bound) in patients with TNBC when their breast cancer has spread or cannot be removed by surgery.

A type of lung cancer called small cell lung cancer (SCLC). Tecentriq may be used with the chemotherapy medicines carboplatin and etoposide as the first treatment in patients with SCLC when their lung cancer:

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

A type of liver cancer called hepatocellular carcinoma (HCC). Tecentriq may be used with the medicine bevacizumab in patients with HCC if:

• Their cancer has spread or cannot be removed by surgery, and
• They have not received other medicines by mouth or injection through their vein (IV) to treat their cancer.

A type of skin cancer called melanoma. Tecentriq may be used with the medicines cobimetinib and vemurafenib in patients with melanoma when their skin cancer:

• has spread to other parts of the body or cannot be removed by surgery, and
• has a certain type of abnormal “BRAF” gene. Healthcare providers will perform a test to make sure this Tecentriq combination is right for the patient.

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

Important Safety Information

What is the most important information about Tecentriq?

Tecentriq can cause the immune system to attack normal organs and tissues in any area of the body and can affect the way they work.
