Priority Review reinforces the significant potential of subcutaneous amivantamab in recurrent or metastatic head and neck cancer, where the current five-year survival rate is only 15 percent Patients achieved rapid, deep and durable responses, including a 42 percent overall response rate with one-third achieving a complete response Subcutaneous amivantamab is the only therapy in head and neck cancer engineered to target both EGFR and MET , proven drivers of tumor growth and treatment resistance RARITAN, N.J. , July 30, 2026 /PRNewswire/ -- Johnson & Johnson (NYSE:JNJ) today announced that the U.S. Food and Drug Administration (FDA) has granted Priority Review to the supplemental Biologics License Application (sBLA) for subcutaneous amivantamab and hyaluronidase-lpuj for adults with recurrent or metastatic head and neck squamous cell carcinoma (HNSCC). If approved, it would provide a new treatment for patients whose disease has progressed following platinum-based chemotherapy and a PD-1 or PD-L1 inhibitor. Priority Review is granted to medicines that may offer significant improvements in safety or effectiveness for serious conditions and shortens the FDA review timeline to approximately six months. 1 "One of the hardest things about advanced head and neck cancer is that it can impact our most basic functions, like the ability to speak, eat, and even breathe easily, profoundly affecting patients' daily lives. For those whose disease progresses despite prior treatment, that burden is compounded by limited treatment options and poor outcomes," said Yusri Elsayed, M.D., M.H.Sc., Ph.D., Global Therapeutic Area Head, Oncology, Johnson & Johnson. "Building on the established role of subcutaneous amivantamab in lung cancer, this milestone underscores its continued potential across multiple tumor types and reflects our commitment to bringing innovative treatment options to patients with cancers driven by EGFR and MET pathways." Subcutaneous amivantamab was designed to target both epidermal growth factor receptor (EGFR) and mesenchymal-epithelial transition (MET) while engaging the immune system, offering a differentiated scientific approach in recurrent or metastatic head and neck squamous cell carcinoma. 2 Overexpression of EGFR and MET receptors is seen in 80 to 90 percent of head and neck squamous cell carcinoma tumors and has been implicated in tumor progression and treatment resistance. 3 Priority Review supported by pivotal results ezstandalone.cmd.push(function () { ezstandalone.showAds(131); }); The FDA's decision to grant Priority Review is supported by results from the pivotal Phase 1b/2 OrigAMI-4 study, which showed that 42 percent of patients responded to treatment with monotherapy subcutaneous amivantamab, with more than one-third of responders achieving a complete response. The study excluded patients with oropharyngeal squamous cell carcinoma caused by human papillomavirus (HPV), as well as those who had received prior anti-EGFR therapy. The findings were presented at the 2026 American Society for Clinical Oncology (ASCO) and published simultaneously in the Journal of Clinical Oncology . 4,5 RYBREVANT FASPRO ™ is approved in more than 40 countries, including the United States, Europe, and Japan, as a subcutaneous treatment for non-small cell lung cancer and continues to be evaluated in additional tumor types as part of Johnson & Johnson's broader commitment to advancing transformational oncology therapies. About the OrigAMI-4 Study OrigAMI-4 ( NCT06385080 ) is an open-label Phase 1b/2 study evaluating RYBREVANT FASPRO™ (amivantamab and hyaluronidase-lpuj) in recurrent or metastatic head and neck squamous cell carcinoma (R/M HNSCC). The study includes six cohorts exploring RYBREVANT FASPRO™ across different treatment settings and regimens. Cohort 1 evaluated RYBREVANT FASPRO™ as monotherapy in patients with R/M HNSCC who had received prior platinum-based chemotherapy and PD-1/PD-L1 immunotherapy. Patients with HPV-positive oropharyngeal squamous cell carcinoma were excluded, as well as those with prior anti- EGFR therapy. RYBREVANT FASPRO™ was administered on a weekly schedule during the initial treatment period followed by dosing every three weeks (Q3W), with weight-based dosing adjustments. The primary endpoint across cohorts is overall response rate (ORR), as assessed by investigators, using RECIST v1.1. † 6 About Head and Neck Squamous Cell Carcinoma Head and neck squamous cell carcinoma (HNSCC) is the most common form of head and neck cancer, a group of cancers that arise in the mouth, throat, voice box, sinuses, nasal cavity, and salivary glands. 7 It represents approximately 4.5 percent of all cancers worldwide and is the seventh most common cancer globally. 7 Major risk factors include tobacco and alcohol use, as well as infection with high-risk human papillomavirus (HPV). 7 Approximately 80 percent of recurrent or metastatic HNSCC are not driven by HPV, and are typically associated with poorer prognosis and reduced response to treatment. 7,8,9 Despite advances in surgery, radiation, chemotherapy, and immunotherapy, many patients ultimately progress to advanced recurrent or metastatic disease. 10,11 About RYBREVANT FASPRO™ and RYBREVANT ® RYBREVANT FASPRO ™ (amivantamab and hyaluronidase-lpuj) received U.S. FDA approval in December 2025 and is approved in multiple markets worldwide for the treatment of adults with EGFR -mutated non-small cell lung cancer (NSCLC), including those with exon 19 deletions, exon 21 L858R substitution mutations, and exon 20 insertion mutations. It is the only subcutaneous therapy approved for these EGFR -mutated NSCLC populations and may be used as monotherapy or in combination with LAZCLUZE ® (lazertinib) or chemotherapy, depending on the specific mutation and treatment setting. For eligible patients, RYBREVANT FASPRO ™ offers a once-monthly dosing option following initial weekly dosing. RYBREVANT FASPRO ™ is co-formulated with recombinant human hyaluronidase PH20 (rHuPH20), Halozyme's ENHANZE ® drug delivery technology. RYBREVANT FASPRO™ is approved in the U.S. for the same indications as intravenous RYBREVANT ® (amivantamab-vmjw) across multiple markets. RYBREVANT ® is a first-in-class, fully human bispecific antibody targeting EGFR and MET, designed to inhibit tumor growth while engaging the immune system. The effectiveness of RYBREVANT FASPRO ™ is supported by the established clinical pro RYBREVANT ® , including data from multiple Phase 3 studies such as MARIPOSA , which demonstrated improvements in progression-free and overall survival when used in combination with LAZCLUZE ® in first-line advanced EGFR -mutated NSCLC. The National Comprehensive Cancer Network ® (NCCN ® ) Clinical Practice Guidelines in Oncology (NCCN Guidelines ® ) ‡ 12 include amivantamab-vmjw (RYBREVANT ® ) across its FDA-approved treatment settings, including as a Category 1 preferred option in combination with lazertinib (LAZCLUZE ® ) for first-line treatment of patients with locally advanced or metastatic NSCLC with EGFR exon 19 deletions or exon 21 L858R mutations. Subcutaneous amivantamab and hyaluronidase-lpuj (RYBREVANT FASPRO ™) may be substituted for IV amivantamab-vmjw (RYBREVANT ® ) where appropriate. See the latest NCCN Guidelines ® for NSCLC for complete information. § || The NCCN Guidelines for Central Nervous System Cancers also include amivantamab (RYBREVANT ® )-based regimens, including in combination with lazertinib (LAZCLUZE ® ), as the only NCCN-preferred combination options for patients with EGFR -mutated NSCLC and brain metastases. § || Beyond NSCLC, RYBREVANT-based therapies are being investigated across other solid tumors, including head and neck and colorectal cancers.
