EPI-326 for EGFR-mutant non-small cell lung cancer and head and neck squamous cell carcinoma

A First-in-Human, Open-label, Multicenter, Phase 1 Study of EPI-326 in Patients With Epidermal Growth Factor Receptor-Mutant Non-small Cell Lung Cancer and Head and Neck Squamous Cell Carcinoma

Phase 1 Interventional EpiBiologics · NCT07462377

This phase 1 trial will try EPI-326, a new drug, in people with EGFR-mutant non‑small cell lung cancer or advanced head and neck squamous cell carcinoma to find safe doses, study how the body handles it, and look for early signs it shrinks tumors.

What this trial studies

This first-in-human, multicenter, open-label Phase 1 dose-escalation trial will give ascending single-agent doses of EPI-326 to patients with EGFR-mutant locally advanced or metastatic NSCLC and to patients with locally advanced or metastatic HNSCC. The primary focus is on safety and tolerability while collecting pharmacokinetic and pharmacodynamic data, along with preliminary anti-tumor activity. Eligible NSCLC participants must have a documented EGFR mutation by clinically validated testing; all participants must have adequate organ function and an ECOG performance status of 0–2. Patients will remain on treatment until disease progression, unacceptable toxicity, withdrawal of consent, or study termination.

Who should consider this trial

Good fit: Ideal candidates are adults with pathologically confirmed locally advanced or metastatic HNSCC or NSCLC harboring a documented EGFR mutation, with ECOG 0–2, life expectancy over 12 weeks, and adequate organ function.

Not a fit: Patients without EGFR mutations, those with symptomatic brain metastases, uncontrolled illnesses, recent second malignancies within three years, poor organ function, or inability to attend the listed U.S. sites are unlikely to qualify or benefit.

Why it matters

Potential benefit: If successful, EPI-326 could offer a new targeted treatment option for patients with EGFR-mutant NSCLC or advanced HNSCC and may improve disease control with an acceptable safety profile.

How similar studies have performed: This is a first-in-human trial of EPI-326, although other EGFR-targeted therapies such as tyrosine kinase inhibitors and antibodies have shown clear benefit in EGFR-mutant NSCLC, while targeted approaches in HNSCC have been less consistently effective.
