On February 18, 2026 Johnson & Johnson (NYSE: JNJ) reported that the U.S. Food and Drug Administration (FDA) has granted Breakthrough Therapy Designation (BTD) for subcutaneous amivantamab and hyaluronidase-lpuj as a monotherapy for the treatment of adults with head and neck squamous cell carcinoma that is recurrent or metastatic and human papillomavirus (HPV)-unrelated after disease progression on or after platinum-based chemotherapy and a PD-1 or PD-L1 inhibitor. RYBREVANT FASPRO is approved in multiple settings for the treatment of locally advanced or metastatic non-small cell lung cancer and is also being evaluated in additional solid tumors, including colorectal cancer.

HPV-unrelated recurrent or metastatic head and neck squamous cell carcinoma is characterized by high rates of epidermal growth factor receptor (EGFR) expression and mesenchymal-epithelial transition (MET) pathway overexpression.1,2,3 Subcutaneous amivantamab is designed to target both pathways, while activating the immune system. The clinical activity observed to date supports further evaluation in this setting, where treatment options remain limited after prior lines of therapy.4
"Patients with HPV-unrelated recurrent or metastatic head and neck cancer often face rapid disease progression and have limited treatment options," said Kiran Patel, Vice President, Global Head, Solid Tumor Clinical Development and Diagnostics, Johnson & Johnson. "Receiving Breakthrough Therapy Designation underscores the FDA’s recognition of these early clinical data and the urgent need for new therapies. Dual targeting EGFR and MET has shown meaningful clinical benefit in lung cancer, helping patients live longer by changing disease biology and preventing treatment resistance. We are now applying this same multi-targeted approach in head and neck cancer with the goal of improving outcomes for patients."
The BTD is supported by data from the open–label Phase 1b/2 OrigAMI–4 study. Results were presented in a mini-oral session at the 2025 European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) Congress and demonstrate promising clinical activity, with rapid and durable responses, in a heavily pretreated patient population.5 Based on these findings, subcutaneous amivantamab is being further evaluated in the ongoing Phase 3 OrigAMI-5 study (NCT07276399), which is assessing the subcutaneous formulation of amivantamab in combination with pembrolizumab and carboplatin versus 5-fluorouracil (5FU) plus pembrolizumab and platinum-based chemotherapy (cisplatin or carboplatin) as a first-line treatment in patients with HPV-unrelated recurrent or metastatic head and neck squamous cell carcinoma, regardless of PD-L1 expression.6
The FDA grants BTD to expedite the development and regulatory review of investigational medicines intended to treat serious or life-threatening conditions, where preliminary clinical evidence indicates the therapy may demonstrate substantial improvement over available treatment options on at least one clinically meaningful endpoint.7
About the OrigAMI-4 Study
OrigAMI-4 (NCT06385080) is an open-label Phase 1b/2 study evaluating RYBREVANT FASPRO in recurrent or metastatic head and neck squamous cell carcinoma (R/M HNSCC). The study includes five cohorts, including Cohort 1, which studied RYBREVANT FASPRO 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. RYBREVANT FASPRO 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**.8
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.9 It develops in the mucosal linings of the oral cavity, oropharynx, hypopharynx, and larynx.9 Major risk factors include tobacco and alcohol use, as well as infection with high-risk human papillomavirus (HPV).9 Around 75 percent of cases are HPV-negative, which is typically associated with a poorer prognosis and reduced response to treatment.9,10 Despite advances in surgery, radiation, chemotherapy, and immunotherapy, many patients ultimately progress to advanced, recurrent or metastatic disease.1,4
About RYBREVANT FASPRO and RYBREVANT
In December 2025, the U.S. FDA approved RYBREVANT FASPRO (amivantamab and hyaluronidase-lpuj) across all indications of intravenous RYBREVANT (amivantamab-vmjw). This subcutaneously administered therapy is also approved in Europe, Japan, China, and other markets.
RYBREVANT FASPRO is co-formulated with recombinant human hyaluronidase PH20 (rHuPH20), Halozyme’s ENHANZE drug delivery technology.
The effectiveness of RYBREVANT FASPRO has been established based on adequate and well-controlled studies of RYBREVANT. Data across multiple Phase 3 studies, including MARIPOSA, have demonstrated the clinical benefit of RYBREVANT in improving progression-free survival (PFS) and overall survival (OS) in advanced EGFR-mutated non-small cell lung cancer (NSCLC).
RYBREVANT is approved in the U.S., Europe and other markets across four indications in EGFR-mutated NSCLC, including two in the first-line setting and two in the second line, for patients with either exon 19 deletions, exon 21 L858R mutations, or exon 20 insertion mutations, as monotherapy or in combination with LAZCLUZE (lazertinib) or chemotherapy.
RYBREVANT is a first-in-class, fully-human bispecific antibody targeting EGFR and MET with immune cell-directing activity.
The National Comprehensive Cancer Network (NCCN) Clinical Practice Guidelines in Oncology (NCCN Guidelines)§11 include amivantamab-vmjw (RYBREVANT) across multiple treatment settings, including its recent inclusion as a NCCN Category 1 preferred option when used with lazertinib (LAZCLUZE) for first-line treatment of people with locally advanced or metastatic NSCLC with EGFR exon 19 deletions or exon 21 L858R mutations. Amivantamab and hyaluronidase-lpuj subcutaneous injection (RYBREVANT FASPRO) may be substituted for IV amivantamab-vmjw (RYBREVANT). See the latest NCCN Guidelines for NSCLC for complete information.†‡
The NCCN Guidelines for Central Nervous System Cancers also identify amivantamab-vmjw (RYBREVANT)-based regimens, including the combination with lazertinib (LAZCLUZE), as the only NCCN-preferred combination options for patients with EGFR-mutated NSCLC and brain metastases.†‡
The legal manufacturer for RYBREVANT is Janssen Biotech, Inc. For more information, visit: View Source

CONTRAINDICATIONS
RYBREVANT FASPRO is contraindicated in patients with known hypersensitivity to hyaluronidase or to any of its excipients.
WARNINGS AND PRECAUTIONS
Hypersensitivity and Administration-Related Reactions with RYBREVANT FASPRO
RYBREVANT FASPRO can cause hypersensitivity and administration-related reactions (ARRs); signs and symptoms of ARR include dyspnea, flushing, fever, chills, chest discomfort, hypotension, and vomiting. The median time to ARR onset is approximately 2 hours.
RYBREVANT FASPRO with LAZCLUZE
In PALOMA-3 (n=206), all Grade ARRs occurred in 13% of patients, including 0.5% Grade 3. Of the patients who experienced ARRs, 89% occurred with the initial dose (Week 1, Day 1).
Premedicate with antihistamines, antipyretics, and glucocorticoids and administer RYBREVANT FASPRO as recommended. Monitor patients for any signs and symptoms of administration-related reactions during injection in a setting where cardiopulmonary resuscitation medication and equipment are available. Interrupt RYBREVANT FASPRO injection if ARR is suspected. Resume treatment upon resolution of symptoms or permanently discontinue RYBREVANT FASPRO based on severity.
Infusion-Related Reactions with RYBREVANT
RYBREVANT can cause infusion-related reactions (IRR) including anaphylaxis; signs and symptoms of IRR include dyspnea, flushing, fever, chills, nausea, chest discomfort, hypotension, and vomiting. The median time to IRR onset is approximately 1 hour.
RYBREVANT with LAZCLUZE
In MARIPOSA (n=421), IRRs occurred in 63% of patients, including Grade 3 in 5% and Grade 4 in 1% of patients. IRR-related infusion modifications occurred in 54%, dose reduction in 0.7%, and permanent discontinuation of RYBREVANT in 4.5% of patients.
