Signatera™ will be used to evaluate molecular response to APG-157 in the neoadjuvant, induction, and adjuvant settings

Natera, Inc. (NASDAQ: NTRA), a global leader in cell-free DNA and precision medicine, and Aveta Biomics, Inc., a clinical-stage immuno-oncology company advancing first-in-class oral immunotherapies for solid tumors, today announced a strategic partnership supporting AVTA 30-01, Aveta’s global Phase 3 registrational clinical trial evaluating APG-157 in patients with locally advanced head and neck squamous cell carcinoma (LA-HNSCC) (NCT07667296).

APG-157 is Aveta's first-in-class oral immunotherapy intended to expand the benefits of immunotherapy to both immune-cold and immune-hot tumors in patients with LA-HNSCC. APG-157 has received FDA Fast Track and Orphan Drug Designations for this indication.

AVTA 30-01 builds upon previously reported Phase 2 clinical data of APG-157 monotherapy in demonstrating favorable safety, evidence of tumor-control, deep molecular responses, and encouraging event-free survival outcomes. The trial will incorporate serial Signatera testing to assess molecular residual disease (MRD) and treatment response throughout therapy and follow-up. Circulating tumor DNA (ctDNA) has emerged as one of the most promising approaches for detecting MRD and identifying recurrence earlier than conventional imaging alone.

Approximately 826 patients are expected to be enrolled across North America, Europe, Asia-Pacific, and Australia. The study includes separate randomized cohorts for resectable and unresectable locally advanced disease, each with treatment and control arms, and Signatera will be a secondary endpoint. The trial is expected to begin enrollment in 2H’26.

Global annual incidence of head and neck cancer is approximately 950,000,¹ and disease recurrence remains a major cause of mortality despite advances in surgery, radiation therapy, and immunotherapy.

“Patients with locally advanced head and neck cancer continue to face substantial risks of recurrence despite aggressive treatment,” said Parag Mehta, Ph.D., founder and chief executive officer of Aveta Biomics. “We believe APG-157 has the potential to transform treatment by activating anti-tumor immunity in both immune-cold and immune-hot tumors. Incorporating serial Signatera testing into AVTA 30-01 will allow us to further validate the ctDNA findings observed in Phase 2 while generating molecular response data that will advance the understanding of treatment benefits for patients and strengthen the regulatory submission.”

This study adds to the evidence Natera continues to generate in head and neck cancer. The company recently announced a successful readout of the prospective Phase 2 SINERGY trial, supporting Signatera MRD-guided treatment in this histology.

“Growing evidence continues to demonstrate the value of Signatera MRD detection in head and neck cancer,” said Eric Matthews, general manager, biopharma, Natera. “We’re pleased to partner with Aveta on AVTA 30-01 to demonstrate how Signatera has the potential to advance the field and improve care for patients.”
