• New giredestrant data from the lidERA study on its potential as a new standard of care for adjuvant ER-positive breast cancer across all menopausal stages
• Primary results from the persevERA study on the numerical improvement in progression-free survival observed with first-line giredestrant plus palbociclib in advanced, endocrine-sensitive disease
• Overall, nine approved and investigational medicines, including bispecific antibodies, antibody-drug conjugates and brain-permeable molecules, with ASCO data targeting urgent needs in breast, blood, lung and other cancers

Genentech, a member of the Roche Group (SIX: RO, ROP; OTCQX: RHHBY), will present new data from nine approved and investigational medicines across more than 15 indications at the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting, held May 29 to June 2 in Chicago.

"Genentech’s ASCO data reflect our commitment to addressing those cancers that impose the highest burden on patients and society," said Levi Garraway, M.D., Ph.D., chief medical officer and head of Global Product Development. "In particular, our ASCO data highlight significant advances in breast cancer, including the latest results for giredestrant and our evolving approach to HER2-positive metastatic disease."

Redefining the standard of care in breast cancer

Genentech's ASCO 2026 focus is on giredestrant, an investigational, oral, selective estrogen receptor degrader (SERD) being studied in early and advanced estrogen receptor (ER)-positive, human epidermal growth factor receptor 2 (HER2)-negative breast cancer.

This subtype accounts for approximately 70% of breast cancer cases, and the majority are diagnosed in the early stage. Data from three Phase III trials demonstrate giredestrant's potential as a future standard of care endocrine therapy across multiple disease stages:

• lidERA Breast Cancer: Building on the transformational results shared in December 2025, which demonstrated a 30% reduction in the risk of invasive disease recurrence or death, new data will indicate whether the efficacy and safety of giredestrant remain consistent across pre- and post-menopausal patients with early breast cancer. The lidERA data have been submitted to the U.S. Food and Drug Administration (FDA).
• persevERA Breast Cancer: Primary results investigating giredestrant in combination with palbociclib as a first-line therapy in locally advanced or metastatic cancer will be presented. These data will provide context following the announcement that while the study did not meet its primary endpoint, the giredestrant combination showed a numerical improvement in this distinct patient population, suggesting that giredestrant is active in the first-line setting.
• evERA Breast Cancer: New post-progression treatment analyses will be shared exploring the sustained clinical benefit for people treated with giredestrant plus everolimus in the post-cyclin-dependent kinase 4/6 inhibitor setting. The U.S. FDA recently accepted the New Drug Application for giredestrant based on the positive evERA data.

Our ASCO data also highlight progress in HER2-positive breast cancer, an area Genentech has led for over 30 years:

• RG6596/ZN-A-1041 in HER2-positive breast cancer: Preliminary results from a Phase Ic expansion trial will provide early information on the safety and efficacy of ZN-A-1041, a highly blood-brain barrier-permeable, HER2-selective tyrosine kinase inhibitor, in combination with other HER2-targeted therapies, for patients with pre-treated HER2-positive metastatic breast cancer. Designed for enhanced brain penetration, ZN-A-1041 may improve the ability to prevent and treat brain metastases, a major challenge in metastatic breast cancers.

Advancing precision medicine and novel combinations

Genentech is also presenting data from its diverse pipeline targeting specific genetic drivers and difficult-to-treat cancers, including:

• Divarasib in non-small cell lung cancer (NSCLC): Genentech will present results from the Krascendo 170 Phase Ib/II study evaluating the next-generation oral KRAS G12C inhibitor divarasib combined with pembrolizumab in treatment-naive patients with KRAS G12C+ advanced NSCLC. These data informed the Phase III Krascendo 2 study, which investigates this combination as a first-line therapy regardless of PD-L1 status. Divarasib is currently being evaluated in three pivotal Phase III studies as a monotherapy or in chemotherapy-free combinations.
• Lunsumio^® (mosunetuzumab) plus Polivy^® (polatuzumab vedotin) in diffuse large B-cell lymphoma (DLBCL): Genentech will present updated data from the Phase III SUNMO trial to further establish the efficacy and safety of Lunsumio plus Polivy compared to chemotherapy (R-GemOx) particularly in second-line patients with relapsed/refractory DLBCL who are not eligible for transplant. This first combination of a bispecific antibody and antibody-drug conjugate could potentially provide patients who often face poor prognoses and significant treatment burdens with an effective, fixed-duration, chemotherapy-free regimen.
