Responses were rapid and durable, and tumor shrinkage was observed in 82 percent of patients New findings from this investigational study build on the strength of RYBREVANT® (amivantamab-vmjw) in non-small cell lung cancer and broadens its potential across additional solid tumors RARITAN, N.J., Oct. 19, 2025 /PRNewswire/ -- Johnson & Johnson (NYSE:JNJ) today announced promising new results from the Phase 1b/2 OrigAMI-4 study evaluating the efficacy and safety of subcutaneous (SC) amivantamab monotherapy in patients with human papillomavirus (HPV)-unrelated, recurrent or metastatic head and neck squamous cell carcinoma (R/M HNSCC) after disease progression on a checkpoint inhibitor and platinum-based chemotherapy. The study used the new subcutaneous formulation of amivantamab, which can be delivered in a five-minute manual injection, offering increased patient convenience compared to intravenous RYBREVANT® (amivantamab-vmjw). Data were presented during a mini-oral session at the European Society for Medical Oncology (ESMO) 2025 Congress (Oral Abstract #1327MO).1 Patients with R/M HNSCC have limited options and poor outcomes after disease progression on a PD-1 or PD-L1 inhibitor and platinum-based chemotherapy.2 Many are unable to receive further treatment, and for those who do, response rates with available therapies are typically only 10 to 24 percent.2,3,4 Survival remains short, with a median of 6 to 9 months, and may be even shorter among patients with HPV-unrelated disease.2,4,5,6 Patients also face a significant burden of symptoms such as difficulty swallowing, impaired speech, pain and fatigue.2 Epidermal growth factor receptor (EGFR) and MET, two key tumor drivers, are overexpressed in 80 to 90 percent of HNSCC tumors, highlighting their role as potential treatment targets.7,8,9 RYBREVANT®, the world's first bispecific antibody approved for lung cancer, inhibits EGFR and MET, in addition to activating the immune system to attack cancer cells.10 "Patients with recurrent or metastatic head and neck cancer face an aggressive disease that significantly impacts their quality of life," said Professor Kevin Harrington*, MBBS, Ph.D., Professor in Biological Cancer Therapies at The Institute of Cancer Research, Royal Marsden Hospital, London, UK, and primary study investigator. "These results represent one of the most encouraging response rates we've seen in this difficult-to-treat setting, with durability that could meaningfully extend the time patients live without their disease progressing." In Cohort 1 of the OrigAMI-4 study, treatment with SC amivantamab resulted in an overall response rate (the primary endpoint) of 45 percent in 38 efficacy-evaluable patients with R/M HNSCC unrelated to HPV with disease progression on or after a PD-1 or PD-L1 checkpoint inhibitor and platinum-based chemotherapy (95 percent confidence interval [CI], 29-62).1 Responses occurred quickly, with a median time to first response of 6.4 weeks (range, 5.7-18.3), and were durable, with a median duration of response of 7.2 months (95 percent CI, 5.3-not estimable [NE]).1,11 Tumor shrinkage of target lesions was observed in 82 percent of patients after 8.3 months follow-up.1 Median progression-free survival was 6.8 months (95 percent CI, 4.2-9.0), while median overall survival had not yet been reached (95 percent CI, 7.7-NE).1 "These data highlight the broader potential of RYBREVANT-based therapies across solid tumors where the EGFR and/or MET pathways are activated," said Kiran Patel, Vice President, Global Head, Solid Tumor Clinical Development and Diagnostics, Johnson & Johnson Innovative Medicine. "RYBREVANT combinations have already demonstrated significant results for certain patients with non-small cell lung cancer, leading to extended survival and delayed treatment resistance. Now we're building on that progress in other hard-to-treat diseases like head and neck cancer. By targeting EGFR and MET while also engaging the immune system, subcutaneous amivantamab could provide new options for more patients who have few effective treatments." The safety-evaluable population included 86 patients who received at least one dose of SC amivantamab monotherapy. The safety profile was consistent with prior SC amivantamab monotherapy studies, with no new safety signals observed. The most common treatment-emergent adverse events were fatigue (31 percent), hypoalbuminemia (31 percent) and stomatitis (23 percent). Administration-related reactions occurred in seven percent of patients, all mild to moderate (grade 1-2), with no severe events. Treatment discontinuation due to treatment-related adverse events occurred in two percent of patients.1 Based on these results, Johnson & Johnson is initiating further study of SC amivantamab in head and neck cancer with the Phase 3 OrigAMI-5 study, which is evaluating first-line SC amivantamab with pembrolizumab and carboplatin versus 5-fluorouracil (5FU) plus pembrolizumab and platinum-based chemotherapy (cisplatin or carboplatin) in patients with HPV-unrelated R/M HNSCC. In addition to supporting further evaluation in first-line R/M HNSCC, these findings add to the evidence supporting the role of RYBREVANT®-based treatments across multiple solid tumors, including non-small cell lung cancer, colorectal cancer and HNSCC. About the OrigAMI-4 Study OrigAMI-4 (NCT06385080) is an open-label Phase 1b/2 study evaluating SC amivantamab in recurrent or metastatic head and neck squamous cell carcinoma (R/M HNSCC). The study includes five cohorts, including Cohort 1, which studied SC amivantamab as monotherapy in patients with human papillomavirus (HPV)-unrelated R/M HNSCC who had received prior platinum-based chemotherapy and PD-1/PD-L1 immunotherapy. Patients with prior anti-EGFR therapy were excluded. Subcutaneous amivantamab was administered every three weeks (Q3W) at 2400 mg, or 3360 mg for patients weighing 80 kg or more. The primary endpoint is overall response rate (ORR), assessed by blinded independent central review (BICR) using RECIST v1.1**.12 About Head and Neck Squamous Cell Carcinoma Head and neck squamous cell carcinoma (HNSCC) is the most common type of head and neck cancer, accounting for more than 90 percent of cases and approximately 4.5 percent of all cancers worldwide.13 It develops in the mucosal linings of the oral cavity, oropharynx, hypopharynx, and larynx.13 Major risk factors include tobacco and alcohol use, as well as infection with high-risk human papillomavirus (HPV).13 Around 75 percent of cases are HPV-negative, which is typically associated with a poorer prognosis and reduced response to treatment.13,14 Despite advances in surgery, radiation, chemotherapy, and immunotherapy, many patients are diagnosed at an advanced stage, and recurrent or metastatic HNSCC continues to carry a poor prognosis.2,7 About Subcutaneous Amivantamab Subcutaneous amivantamab is an investigational fixed-dose combination of the bispecific antibody amivantamab and recombinant human hyaluronidase PH20 (rHuPH20), which is part of Halozyme's ENHANZE® drug delivery technology. It targets EGFR and MET with immune cell-directing activity and is being developed to address tumors driven by activating and resistance EGFR mutations as well as MET alterations. Subcutaneous amivantamab is being studied across multiple tumor types, including head and neck squamous cell carcinoma (HNSCC) and non-small cell lung cancer (NSCLC).
