Roche’s divarasib demonstrated best-in-class efficacy, advancing the standard of care in previously treated KRAS G12C-mutated lung cancer

Roche Holding

Basel, 25 October 2026 - Roche (SIX: RO, ROP; OTCQX: RHHBY) announced today pivotal results from the phase III Krascendo 1 study, which demonstrated the superior efficacy of investigational divarasib, a next-generation KRAS G12C inhibitor, compared with current standard of care KRAS G12C inhibitors in people with previously treated KRAS G12C-mutated non-small cell lung cancer (NSCLC).1,2 Participants treated with divarasib monotherapy lived significantly longer, lowering the risk of death by 44% compared with sotorasib or adagrasib (overall survival, OS, HR 0.56, [95% CI: 0.41-0.78], p=0.0005).1,2 Median OS for divarasib is currently approximately 18 months, compared to 12 months for the control arm (see table below).1,2 No new safety findings were observed with divarasib and the most common treatment-related adverse events (TRAEs) were mainly low grade and manageable.1,2 These data were presented as a late-breaking abstract during a Presidential Symposium at the 2026 European Society for Medical Oncology (ESMO) Congress and simultaneously published in The New England Journal of Medicine.1,2

"The superior efficacy against the current standard of care demonstrated in this head-to-head trial reinforces divarasib's best-in-class profile. We are working closely with health authorities to bring this new treatment option to the people who need it.” The G12C mutation is one of the most common KRAS mutations, found in approximately one in eight people with NSCLC.3,4 Accumulating evidence suggests that people with NSCLC who have the KRAS G12C mutation may have poorer outcomes than those who have the unmutated KRAS gene (wild-type disease).5,6 Despite the approval of current, first-generation KRAS G12C-targeted treatments, there remains a significant unmet need for more effective therapy options. “New life-extending treatments are greatly needed, as most patients with this type of cancer will eventually relapse after initial therapy, and there are limited effective treatments for recurrent disease,” said study lead author Ferdinandos Skoulidis, MD, PhD, Professor of Thoracic/Head and Neck Medical Oncology at The University of Texas MD Anderson Cancer Center. “The Krascendo 1 results highlight divarasib’s practice-changing potential, as the first KRAS inhibitor to meaningfully improve overall survival for people with previously treated KRAS G12C-mutated lung cancer, compared with current treatment options.” The Krascendo 1 study is the only global head-to-head study to evaluate a next-generation KRAS G12C inhibitor versus approved first-generation KRAS G12C inhibitors.1,2 The study met primary and key secondary endpoints, and divarasib demonstrated statistically significant and clinically meaningful improvements in OS and progression-free survival (PFS) over sotorasib or adagrasib.1,2 In addition to the OS benefit, divarasib reduced the risk of disease progression or death by 42% (PFS HR 0.58, [95% CI: 0.44-0.76], p<0.0001).1,2 The OS and PFS benefit was consistent across clinically relevant subgroups, and was observed regardless of PD-L1 expression or KEAP1 mutation status.1,2 The objective response rate (ORR) with divarasib was nearly double that of sotorasib or adagrasib.1,2 Key efficacy results from the phase III Krascendo 1 study:1,2 Primary and key secondary endpointsDivarasib arm (n=167)*Control arm (adagrasib, sotorasib) (n=171)*Hazard Ratio / (95% CI)p-value Median OS (months) 17.712.0HR 0.56 (0.41-0.78)p=0.0005 Median PFS (months) 9.8 5.7 HR 0.58 (0.44-0.76)p<0.0001 12-month PFS rate (%)44% 24%-- Confirmed ORR (%)*58%32%-- Median DOR (months)* 11.96.9-- *Assessed in response-evaluable population (n=328; ten patients [divarasib arm, n=6; control arm, n=4] did not have measurable disease at baseline and were excluded from the response-evaluable set). Duration of Response (DOR) evaluated in those who responded to treatment (divarasib arm, n=94; control arm, n=54). The safety profile of divarasib monotherapy was consistent with the known class effects of KRAS G12C inhibitors.1,2 The most common TRAEs comprised GI toxicity (most commonly, diarrhoea, nausea, and vomiting) and hepatotoxicity.1,2 Fewer participants discontinued treatment due to TRAEs with divarasib (4.8% versus 11.7%) and the rate of serious TRAEs was approximately half that of sotorasib or adagrasib (7.8% versus 15.2% respectively), despite patients remaining on treatment for more than twice as long (11.3 months compared with 5.0 months).1,2 Roche is advancing a comprehensive phase III clinical development programme in NSCLC, investigating divarasib as both a monotherapy and as a chemotherapy-free combination, across different disease settings and lines of therapy. The US Food and Drug Administration granted Breakthrough Therapy Designation to divarasib in 2022, and in 2026, Orphan Drug Designation for KRAS G12C-mutated NSCLC. About Krascendo 11,2 The Krascendo 1 study [NCT06497556] is the only global head-to-head study evaluating a Kirsten rat sarcoma virus (KRAS) G12C inhibitor in direct comparison with first-generation approved KRAS G12C inhibitors. This phase III, randomised, open-label, multicentre study evaluates the efficacy and safety of divarasib monotherapy versus sotorasib or adagrasib in people with previously treated KRAS G12C-mutated advanced or metastatic non-small cell lung cancer. The study includes 338 adults, randomised to receive either divarasib once daily (n=167) or, either sotorasib once daily or adagrasib twice daily (n=171). The primary endpoint is blinded independent central review (BICR)-assessed progression-free survival. Secondary endpoint measures include overall survival, confirmed objective response, duration of response, as well as other efficacy and safety measures. About divarasib Divarasib is an investigational, best-in-class, next-generation, oral, KRAS G12C inhibitor, discovered and developed by researchers within Roche and Genentech. It has shown greater potency and selectivity in preclinical studies compared with first-generation KRAS G12C-targeting treatments, sotorasib or adagrasib, with superior efficacy demonstrated in people with previously treated KRAS G12C-mutated NSCLC.1,2,7 Divarasib is designed to selectively bind to the KRAS G12C protein, locking the protein in an inactive (off) state, thereby turning off its tumour-driving signalling.7,8,9 Divarasib’s comprehensive clinical development programme is anchored by three phase III studies: StudyInterventionPatient population Krascendo 1 [NCT06497556]Divarasib monotherapy vs sotorasib or adagrasib Previously treated KRAS G12C-mutated advanced or metastatic NSCLC (second-line) Krascendo 2 [NCT06793215]Divarasib plus pembrolizumab (chemotherapy-free combination) vs chemotherapy plus pembrolizumabPreviously untreated KRAS G12C-mutated advanced NSCLC (first-line) Krascendo 3 [NCT07541170]Adjuvant divarasib monotherapy vs immunotherapy or observationResected stage II–IIIB KRAS G12C-mutated NSCLC after standard of care chemoimmunotherapy (early-stage) Divarasib underpins Roche’s diversified pipeline targeting the RAS signalling pathway, including other mutant-selective inhibitors and a pan-RAS inhibitor, designed to extend the benefits of RAS inhibition strategies to more patients. About KRAS G12C-mutated non-small cell lung cancer Despite advances in treatment, lung cancer remains the leading cause of cancer-related deaths worldwide, surpassing the combined mortality rates of breast, prostate, and stomach cancers.10,11 Each year, it claims the lives of 1.8 million people, with non-small cell lung cancer (NSCLC) accounting for approximately 85% of cases.10,12 KRAS is one of the most frequently mutated genes in lung cancer, occurring in approximately 25% of newly diagnosed lung cancers, and is associated with poor prognosis for patients.9 The G12C mutation is one of the most common KRAS mutations, found in approximately 12-14% of NSCLC cases.3,4 The KRAS gene produces the KRAS protein, which acts as a cellular control switch, cycling between an active (on) and inactive (off) state to regulate cell growth and proliferation, making it a critical target for new therapeutic strategies.9 G12C mutation locks the KRAS protein in its active (on) state, leading to continuous, unregulated signalling for cell growth, driving tumour proliferation.8,9 About Roche in lung cancer Roche is committed to advancing the field of lung cancer treatments, leveraging more than 20 years of deep scientific expertise to improve patient outcomes and their overall experience.

Data will be shared with health authorities, with the goal of bringing this treatment to patients as soon as possible. Typically diagnosed before the age of 40, IgAN affects at least 25 adults per million worldwide each year.8,9 IgAN, also known as Berger’s disease, is a chronic and progressive autoimmune disease that leads to end-stage kidney disease in up to 50% of patients within 20 years of diagnosis.5,10 It is the most common form of primary glomerulonephritis (inflammation of the tiny filters, glomeruli, in the kidneys) and is a major cause of chronic kidney disease as well as kidney failure.8 About sefaxersen Investigational sefaxersen is the first highly specific liver-directed antisense oligonucleotide (ASO) inhibitor of factor B production being evaluated in IgA nephropathy (IgAN).2 Serum complement factor B levels are elevated in people with IgAN. When we reduce these levels, it in turn reduces the level of protein in urine, which is a key indicator of improved kidney function.11,12 Sefaxersen is designed to provide sustained control of the alternative complement pathway, an important pathway in IgAN, enabling once-monthly subcutaneous dosing and is intended for self-administration in people with IgAN.3 In phase I and II trials, sefaxersen was shown to be generally well tolerated in healthy volunteers and people with IgAN who were at high risk of progression, and reduced proteinuria and plasma complement factor B.2,13 Roche licensed sefaxersen from Ionis Pharmaceuticals for the treatment of complement mediated diseases. About the IMAgINATION study IMAgINATION [NCT05797610] is a phase III, multicentre, randomised, double-blind, placebo-controlled study to evaluate the efficacy and safety of subcutaneous sefaxersen, an investigational antisense inhibitor of complement factor B, in patients with primary IgA nephropathy at high risk of progression.1,14 The study enrolled 459 people, who are randomised 1:1 to receive sefaxersen or placebo for 105 weeks.1,14 Participants may switch to open-label treatment after week 105 at the investigator's discretion or after the common-close timepoint, whichever occurs first.1,14 The primary endpoint of the study is the change from baseline in the urine protein-to-creatinine ratio at 37 weeks.1,14 About primary immunoglobulin A nephropathy (IgAN) IgAN, also known as Berger’s disease, is a serious, chronic and progressive autoimmune kidney disease affecting at least 25 adults per million worldwide each year and is typically diagnosed before the age of 40 years.8-10 In IgAN, immune complexes deposit in the kidneys, which activates the complement system’s alternative pathway, leading to inflammation and subsequent kidney damage.15 It is the most common form of primary glomerulonephritis (inflammation of kidney glomeruli) and remains a leading cause of kidney failure, with up to 50% of patients experiencing end-stage kidney disease within 20 years of diagnosis.5,8 Many current therapies aim to reduce protein levels in the urine and control blood pressure to slow progression of the disease.16 Updated KDIGO 2025 guidelines* highlight the need to address both the underlying immune-mediated causes of IgAN and the downstream consequences of kidney damage.4 While new therapies have expanded treatment options, important unmet needs remain, including improved long-term preservation of kidney function and more targeted approaches that address key drivers of disease progression.4,16 About Roche in Immunology For over two decades, Roche has advanced immune system research, creating groundbreaking targeted treatments that have transformed care for people with blood disorders, neurological conditions and autoimmune diseases. With a development pipeline exploring more than 20 medical approaches, we are targeting widespread, complex conditions like chronic lung disease (COPD) and inflammatory bowel disease (IBD), alongside lupus and autoimmune kidney diseases. Our ultimate goal is to lessen the burden of chronic immune disorders on patients, healthcare systems, and society.
