Genentech to Present Pivotal Data at ESMO 2026, Showcasing Advances Across Its Lung and Breast Cancer Late-Stage Portfolio

• Phase III Krascendo 1 results demonstrated divarasib’s superiority over current standard of care, first-generation KRAS G12C inhibitors, in previously treated advanced G12C-mutated non-small cell lung cancer 
• Patient-reported outcomes from Phase III lidERA study showed improved efficacy of giredestrant over standard endocrine therapy is achieved without compromising tolerability and health-related quality of life in early-stage breast cancer
• Second Phase III results in Chinese patients with metastatic nasopharyngeal carcinoma demonstrate the potential of Tam-Peli, a next-generation B7-H3 targeted ADC, to deliver robust efficacy with a favorable safety profile in high-unmet-need solid tumors

South San Francisco, CA -- October 18, 2026 --

Genentech, a member of the Roche Group (SIX: RO, ROP; OTCQX: RHHBY), will present new data, including two late-breaking abstracts, across lung, breast and other cancers at the 2026 European Society for Medical Oncology (ESMO) Annual Meeting, held from October 23 to 27 in Madrid.  

 

“Our presentations at ESMO 2026 highlight the depth and impact of Genentech’s oncology pipeline, driven by emerging science capable of bringing new treatment benefits across diverse and high-unmet-need cancers,” said Levi Garraway, M.D., Ph.D., chief medical officer and head of Global Product Development. “From establishing head-to-head superiority with divarasib in KRAS G12C-mutated lung cancer to advancing patient-centered oral SERD therapies like giredestrant and next-generation ADCs such as Tam-Peli, we are committed to delivering medicines that not only extend life, but also seek to improve treatment experience, tolerability and quality of life for people living with cancer.” 

     

Divarasib demonstrated superior efficacy and best-in-class potential in KRAS G12C NSCLC 

Genentech will share Phase III Krascendo 1 results, which demonstrated divarasib’s best-in-class efficacy, advancing the standard of care in previously treated KRAS G12C-mutated lung cancer.

• Krascendo 1 is the only global head-to-head trial to evaluate a next-generation KRAS G12C inhibitor versus approved first-generation inhibitors.
• Results for this potential best-in-class, next-generation KRAS G12C-targeted therapy will be presented as a late-breaking abstract during a Presidential Symposium.

 

Giredestrant data support its potential to become the new standard of care in early-stage and advanced breast cancer

Genentech will present new data highlighting the potential role of giredestrant, an investigational, oral, potent next-generation selective estrogen receptor degrader (SERD) and full antagonist, in estrogen receptor (ER)-positive, human epidermal growth factor receptor 2 (HER2)-negative breast cancer, a subtype in which more than 90% of cases are diagnosed at an early stage (I-III). Key presentations from early-stage to advanced disease include:

• Patient-reported outcomes from the Phase III lidERA Breast Cancer trial suggesting that the improved efficacy of giredestrant compared to endocrine therapy is achieved without compromising tolerability or Health-Related Quality of Life.
• Exploratory biomarker findings from the evERA Breast Cancer trial of giredestrant in combination with everolimus in ER-positive, HER2-negative advanced breast cancer in the post-cyclin-dependent kinase 4/6 inhibitor setting.
• Updated interim results for giredestrant plus inavolisib from the MORPHEUS Breast Cancer trial evaluating giredestrant treatment combinations in ER-positive, HER2-negative locally advanced or metastatic breast cancer.

 

Data demonstrate the potential of a next generation B7-H3 targeted antibody-drug conjugate (ADC) Tam-Peli (tambotatug pelitecan)

New data will also be presented for Tam-Peli, an investigational next-generation B7-H3-targeted ADC designed to deliver high-potency anti-tumor activity while limiting off-target toxicity. Tam-Peli is currently being investigated across multiple solid tumor indications:

• ESMO data include late-breaking interim Phase III results in heavily pretreated recurrent/metastatic nasopharyngeal carcinoma, analyses of interstitial lung disease in patients with advanced solid tumors from Phase I/II studies, and Phase I efficacy and safety data for Tam-Peli in patients with locally advanced or metastatic NSCLC.
• These findings build on the TAISHAN-302 Phase III data in second-line small cell lung cancer presented at the World Conference on Lung Cancer in September, where the study met all three specified endpoints of overall survival, progression free survival and objective response rate at its first interim analysis.
• Roche is developing and commercializing Tam-Peli outside mainland China, Hong Kong, and Macau, and plans to rapidly initiate global trials across multiple tumor types.
