Over 70 percent of patients in the first-line subgroup responded to amivantamab plus chemotherapy with most responses lasting beyond 16 months
Notable responses were also seen in patients with liver metastases, who often face poorer outcomes with this disease
RARITAN, N.J., Jan. 10, 2026 /PRNewswire/ -- Johnson & Johnson (NYSE:JNJ) today announced new longer follow-up results from the investigational Phase 1b/2 OrigAMI-1 study evaluating amivantamab-vmjw, a bispecific antibody targeting epidermal growth factor receptor (EGFR) and MET, in combination with FOLFOX or FOLFIRI chemotherapy in patients with RAS/BRAF wild-type metastatic colorectal cancer. The encouraging anti-tumor activity, durable responses, and low rates of treatment-related discontinuations observed in this study support further investigation in ongoing Phase 3 studies in first- and second-line colorectal cancer. Results were presented during a poster session at the 2026 American Society of Clinical Oncology Gastrointestinal Cancers (ASCO GI) Symposium (Abstract #166).1
"These results show the potential of amivantamab combined with chemotherapy to deliver meaningful and durable benefit for people with advanced colorectal cancer, including for those with liver metastases who have historically faced poorer outcomes," said Dr. Filippo Pietrantonio,* M.D., Head of the Gastrointestinal Oncology Unit, IRCCS Foundation, National Cancer Institute, Milan, Italy. "Seeing patients maintain responses for extended periods, some beyond two years, is a powerful sign of progress in a disease where sustained efficacy has been hard to achieve and speaks to the promise of this treatment approach."
Colorectal cancer is the third most commonly diagnosed cancer worldwide, and a leading cause of cancer-related death.2 While traditionally seen in older adults, incidence is rising in people under 50.3 More than half of patients will eventually develop metastatic disease, with liver involvement in roughly 70 percent of cases. In this setting, resistance to current first-line therapies often develops early, shortening the time patients can benefit.4 For those with RAS/BRAF wild-type metastatic colorectal cancer with disease progression, second-line options remain limited, with historical response rates of 32 to 36 percent and median progression-free survival (PFS) of 5.4 to 6.4 months using EGFR inhibitors and chemotherapy.5,6,7,8,9,10 Research has shown that MET alterations are a frequent cause of resistance to EGFR-inhibition, highlighting a need for new approaches that target both pathways simultaneously.11
Detailed Study Results
Cohorts D and E of the Phase 1b/2 OrigAMI-1 study evaluated intravenous amivantamab as monotherapy or in combination with either FOLFOX or FOLFIRI chemotherapy in patients with RAS/BRAF wild-type metastatic colorectal cancer. Patients were confirmed to be negative for KRAS, NRAS, BRAF and EGFR mutations, and did not have HER2 amplification. They could have received one prior line of systemic therapy in the metastatic setting, and prior treatment with an EGFR inhibitor was not permitted. The primary endpoint was safety, and secondary endpoints included overall response rate (ORR), duration of response (DOR), clinical benefit rate, and PFS. Overall survival was assessed as an exploratory endpoint.1
At a median follow-up of 16 months (range, 1.2-29.5), amivantamab plus FOLFOX (n=20) or FOLFIRI (n=23) achieved a confirmed ORR of 51 percent (95 percent confidence interval [CI], 36-67) across the study, with responses observed early and a median time to first response of 8.3 weeks (range, 7.3-20.3), along with a median DOR of 9.3 months (95 percent CI, 5.8-14.7). Median PFS was 9.2 months (95 percent CI, 5.4-12.9), and median overall survival was not estimable (NE) (95 percent CI, 16.2-NE). In the first-line subgroup, ORR was 73 percent (95 percent CI, 53-86), with median DOR not yet reached at the time of data cutoff (95 percent CI, 7.3-NE). Among 11 patients treated in the first-line subgroup, four were able to proceed to curative intent surgery. In the second-line subgroup (n=32), ORR was 44 percent (95 percent CI, 26-62) and median DOR was 7.4 months (95 percent CI, 5.4-14.5). More than one-third of patients treated in the second-line setting remained on therapy for over one year, and three patients have stayed on amivantamab treatment for more than two years. In patients with liver metastases (n=30), the study showed notable activity, with an ORR of 57 percent (95 percent CI, 37-75) and a median PFS of 11.3 months (95 percent CI, 5.9-16.4).1
The safety profile remained consistent with prior reports of amivantamab plus chemotherapy in colorectal cancer and with the known safety profiles of the individual agents. Treatment-emergent adverse events were primarily related to EGFR and MET inhibition and known chemotherapy-associated effects. Four patients (9 percent) discontinued therapy due to treatment-related adverse events. The most common Grade 3 or higher event was neutropenia, and no new safety signals were observed.1
"Treatment for metastatic colorectal cancer has remained largely unchanged for many years, underscoring the need for new strategies," said Kiran Patel, M.D., Vice President, Global Head, Solid Tumor Clinical Development and Companion Diagnostics, Johnson & Johnson Innovative Medicine. "We are drawing on our scientific leadership in EGFR-driven lung cancer to evaluate the potential of amivantamab, and its dual-targeting of EGFR and MET, in colorectal cancer and other solid tumors driven by these pathways."
Pivotal Phase 3 studies, including the global, randomized OrigAMI-2 and OrigAMI-3 studies evaluating subcutaneous amivantamab with FOLFOX and FOLFIRI, are underway to further evaluate the potential of amivantamab-based regimens in both first- and second-line colorectal cancer.
About the OrigAMI-1 Study
OrigAMI-1 (NCT05379595) is an open-label, Phase 1b/2 study assessing the efficacy and safety of RYBREVANT® plus mFOLFOX6 or FOLFIRI in anti-EGFR-naïve RAS/BRAF WT mCRC. Eligible patients were wild-type (WT) for KRAS, NRAS or BRAF genes based on circulating tumor DNA testing. Additionally, patients were required to have no amplification of the ERBB2/HER2 gene. In the RYBREVANT® and chemotherapy cohorts, patients were either treatment-naïve or had received at least one prior line in the metastatic setting (no EGFR inhibitor treatment). The primary endpoint of the combination cohorts was to characterize the safety and confirm the dose of RYBREVANT® plus mFOLFOX6 or FOLFIRI. Response was assessed by the investigator per RECIST v1.1.12
About Colorectal Cancer
Colorectal cancer is the third most common cancer worldwide, accounting for approximately 10 percent of all cancer cases, and is the second leading cause of cancer-related deaths worldwide.2 While it predominantly affects older individuals, recent research suggests that colorectal cancer is now being diagnosed in adults under the age of 50 at record rates.3
Left-sided colorectal cancer, which represents approximately 65 percent of cases, often has distinct characteristics that influence treatment strategies. Around half of colorectal cancer patients have mutations in the RAS genes, with KRAS being the most common mutation. While tumors with normal RAS and BRAF genes generally respond better to EGFR inhibitors, those with RAS and BRAF mutations – particularly on the left side – are associated with poorer outcomes.13
