What this Trial Is About
This research aims to evaluate the safety and preliminary effectiveness of amivantamab alone and combined with other treatments in participants with recurrent or metastatic head and neck squamous cell carcinoma HNSCC and in those with locally advanced HNSCC who can undergo surgery. The study also seeks to establish the recommended Phase 2 combination dose of amivantamab when given with paclitaxel. Additionally, the safety and effectiveness of amivantamab combined with pembrolizumab will be assessed before and after surgery in participants with resectable locally advanced HNSCC.
Participants will receive subcutaneous injections of amivantamab at doses adjusted by body weight on specific schedules, either alone or combined with intravenous pembrolizumab, paclitaxel, or carboplatin, depending on their assigned cohort. Dose confirmation and expansion cohorts will help determine the appropriate dosing. For those in the perioperative setting, amivantamab and pembrolizumab will be given in both neoadjuvant before surgery and adjuvant after surgery phases with specific dosing schedules extending up to 15 cycles.
Participants will be assessed for tumor response, treatment-related toxicities, and survival outcomes over a period extending up to about two years. Researchers will monitor treatment-emergent adverse events, dosing tolerability, and measure outcomes such as objective response rate, duration of response, progression-free survival, overall survival, and major pathologic response. Laboratory tests, imaging, and clinical evaluations will be performed to evaluate safety and efficacy throughout the study duration.

Investigational amivantamab‑based regimens (monotherapy or combinations with pembrolizumab, paclitaxel, carboplatin) evaluated across multiple dose‑expansion cohorts
Pembrolizumab alone or combined with platinum‑based chemotherapy represents current standard systemic therapy for recurrent or metastatic HNSCC
Role in study
Participants receive amivantamab, either alone or in combination with other agents, across sequential investigational cohorts
Used as comparator standard of systemic care outside the trial
Primary use
Treatment of recurrent/metastatic or locally advanced resectable HNSCC in different investigational regimens
Approved as frontline or subsequent systemic therapy in R/M HNSCC based on PD‑1 immune checkpoint blockade
Administration
Amivantamab is given subcutaneously alone or with intravenous agents (e.g., pembrolizumab, paclitaxel, carboplatin) per cohort
Pembrolizumab is given intravenously, sometimes with intravenous platinum‑based chemotherapy
Evidence status
OrigAMI‑4 early data show objective responses after prior platinum and immunotherapy in heavily pretreated R/M HNSCC
Pembrolizumab with or without chemotherapy improves survival outcomes compared to prior regimens in R/M HNSCC
Important risks
Risks include EGFR/MET‑related rash, hypoalbuminemia, administration reactions observed in cohort 1
Immune‑related adverse events can occur with pembrolizumab, including rash, fatigue, endocrinopathies
Important limitations
Single‑group, non‑randomized early‑phase data; efficacy and safety not yet compared against standard care
Benefit may vary by PD‑L1 expression and patient fitness; not evaluable in post‑immunotherapy setting
Patient impact
Early responses may offer benefit to heavily pretreated patients, but clinical impact remains exploratory
Pembrolizumab‑based treatments have demonstrated survival benefit and quality‑of‑life maintenance in trials

Your Study Journey
Screening
Duration - 2 to 4 weeks
Participants are screened for eligibility to participate in the trial.
Treatment
Duration - Up to 2 years and 2 months
Participants receive subcutaneous amivantamab alone or combined with intravenous pembrolizumab, paclitaxel, or carboplatin according to their assigned cohort. Dosing schedules include weekly injections during the first cycle, then every three weeks thereafter. Some participants receive neoadjuvant and adjuvant treatments around surgery.
Regular visits every 1 to 3 weeks depending on treatment schedule
