On June 18, 2026 Genentech, a member of the Roche Group (SIX: RO, ROP; OTCQX: RHHBY), reported that the U.S. Food and Drug Administration (FDA) has accepted the company’s supplemental Biologics License Application (sBLA) filing for adjuvant Tecentriq (atezolizumab) and Tecentriq Hybreza (atezolizumab and hyaluronidase-tqjs) in combination with chemotherapy in stage III deficient DNA mismatch repair (dMMR) or microsatellite instability-high (MSI-H) colon cancer, a type of tumor characterized by high mutation rates. The FDA has granted Priority Review and is expected to make a decision on the approval by October 9, 2026.

"This filing acceptance brings us closer to establishing adjuvant Tecentriq plus chemotherapy as a new standard of care for certain types of early colon cancer," said Levi Garraway, M.D., Ph.D., chief medical officer and head of Global Product Development. "The ATOMIC results demonstrate that Tecentriq plus chemotherapy can substantially reduce the risk of disease recurrence or death, helping more patients remain cancer-free following surgery."
"One in three patients with stage III colon cancer will relapse within five years, underscoring the need for new adjuvant treatment options," said Michael Sapienza, CEO, Colorectal Cancer Alliance. "This milestone represents a critical step toward a reality where treatment is tailored to a patient’s specific tumor biology from the very beginning, giving them a better chance of preventing a recurrence."
The application is based on the landmark ATOMIC study, recently published in The New England Journal of Medicine. ATOMIC demonstrated that adding Tecentriq to standard FOLFOX6 chemotherapy reduced the risk of disease recurrence or death by 50%, compared to chemotherapy alone for people with stage III dMMR colon cancer, determined by an immunohistochemistry test, such as the VENTANA MMR RxDx Panel. The 36-month disease-free survival was 86% for Tecentriq combined with FOLFOX6 compared with 76% in the FOLFOX6 alone group. The safety profile was consistent with previous studies of Tecentriq and FOLFOX6.
Colon cancer remains one of the world’s most common and deadliest tumors. Over one million people are diagnosed globally each year, and despite surgery and chemotherapy, approximately 30% of stage III patients relapse within five years. Approximately 15% of colon cancer patients present with dMMR/MSI-H tumors, which indicate a higher mutation rate and thus have the potential to respond to immunotherapy.
The ATOMIC study was sponsored by the National Cancer Institute (NCI) and conducted by the Alliance for Clinical Trials in Oncology in partnership with Genentech and the Arbeitsgemeinschaft Internistische Onkologie (AIO) group in Germany. It highlights Genentech’s commitment to working alongside leading academic groups to tackle some of the most challenging cancers.
About the ATOMIC study
ATOMIC (A021502, NCT02912559) is a Phase III, randomized, open-label, multicenter study investigating the addition of Tecentriq (atezolizumab) to FOLFOX6 chemotherapy (a combination of folinic acid, fluorouracil, and oxaliplatin) in patients with stage III colon cancer who have a deficiency in DNA mismatch repair (dMMR). The trial enrolled 712 patients. Participants were randomized 1:1 to receive either FOLFOX6 plus Tecentriq for 12 cycles (six months) followed by Tecentriq monotherapy for 13 cycles (an additional six months), or FOLFOX6 alone for 12 cycles. The primary endpoint is disease-free survival (DFS).
About Tecentriq (atezolizumab)
Tecentriq is a monoclonal antibody designed to bind with a protein called PD-L1, which is 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 has been approved for some of the most aggressive and difficult-to-treat forms of cancer, and is the first PD-(L)1 cancer immunotherapy available in both subcutaneous and intravenous formulations.
What are Tecentriq and Tecentriq Hybreza?
Tecentriq (atezolizumab) and Tecentriq Hybreza (atezolizumab and hyaluronidase-tqjs) are prescription medicines used to treat:
Adults with a type of lung cancer called non-small cell lung cancer (NSCLC).
Tecentriq or Tecentriq Hybreza may be used alone as a treatment for your lung cancer:
to help prevent your lung cancer from coming back after your tumor(s) has been removed by surgery and you have received platinum-based chemotherapy, and
you have stage 2 to stage 3A NSCLC (talk to your healthcare provider about what these stages mean), and
your cancer tests positive for "PD-L1".
Tecentriq or Tecentriq Hybreza may be used alone as your first treatment when your lung cancer:
has spread or grown, and
your cancer tests positive for "high PD-L1", and
your tumor does not have an abnormal "EGFR" or "ALK" gene.
Tecentriq or Tecentriq Hybreza may be used with the medicines bevacizumab, paclitaxel, and carboplatin as your first treatment when your lung cancer:
has spread or grown, and
is a type called "non-squamous NSCLC", and
your tumor does not have an abnormal "EGFR" or "ALK" gene.
Tecentriq or Tecentriq Hybreza may be used with the medicines paclitaxel protein-bound and carboplatin as your first treatment when your lung cancer:
has spread or grown, and
is a type called "non-squamous NSCLC", and
your tumor does not have an abnormal "EGFR" or "ALK" gene.
Tecentriq or Tecentriq Hybreza may be used alone when your lung cancer:
has spread or grown, and
you have tried chemotherapy that contains platinum, and it did not work or is no longer working.
If your tumor has an abnormal "EGFR" or "ALK" gene, you should have also tried an FDA-approved therapy for tumors with these abnormal genes, and it did not work or is no longer working.
Adults with a type of lung cancer called "extensive stage small cell lung cancer (SCLC)", which is SCLC that has spread or grown
Tecentriq or Tecentriq Hybreza may be used with the chemotherapy medicines carboplatin and etoposide as your first treatment
Tecentriq or Tecentriq Hybreza may be used with the medicine lurbinectedin as maintenance treatment when your lung cancer:
has not progressed after first treatment with Tecentriq or Tecentriq Hybreza and the chemotherapy medicines carboplatin and etoposide.
Adults with a type of liver cancer called hepatocellular carcinoma (HCC). Tecentriq or Tecentriq Hybreza may be used with the medicine bevacizumab when your liver cancer:
has spread or cannot be removed by surgery, and
you have not received other medicines by mouth or injection through your vein (IV) to treat your cancer.
Adults with a type of skin cancer called melanoma. Tecentriq or Tecentriq Hybreza may be used with the medicines cobimetinib and vemurafenib when your melanoma:
has spread to other parts of the body or cannot be removed by surgery, and
has a certain type of abnormal "BRAF" gene. Your healthcare provider will perform a test to make sure this Tecentriq or Tecentriq Hybreza combination is right for you.
Adults and children (12 years of age and older), with a type of soft tissue tumor (cancer) called alveolar soft part sarcoma (ASPS). Tecentriq or Tecentriq Hybreza may be used when your sarcoma:
has spread to other parts of the body or cannot be removed by surgery.
Adults with a type of bladder cancer called muscle invasive bladder cancer (MIBC) that has spread into the muscle layer of the bladder but not to other parts of the body. Tecentriq or Tecentriq Hybreza may be used alone as a treatment for your bladder cancer:
to help prevent your bladder cancer from coming back after your bladder has been removed by surgery, and
small pieces of DNA from the tumor (called circulating tumor DNA [ctDNA]) were found in your blood, showing that cancer cells remain in the body (molecular residual disease). Your healthcare provider will perform a test to make sure that Tecentriq or Tecentriq Hybreza is right for you.
It is not known if Tecentriq Hybreza is safe and effective when used:
in children for the treatment of NSCLC, SCLC, HCC, melanoma or MIBC.
It is not known if Tecentriq is safe and effective when used:
in children younger than 2 years of age for the treatment of ASPS.
in children for the treatment of NSCLC, SCLC, HCC, melanoma or MIBC.
