SAN DIEGO--(BUSINESS WIRE)--Nov 10, 2025--

Avenzo Therapeutics, Inc. (“Avenzo”), a clinical-stage biotechnology company developing next-generation oncology therapies, today announced the U.S. Food and Drug Administration (FDA) granted Fast Track designation to AVZO-1418 (DB-1418), a potential best-in-class EGFR/HER3 bispecific antibody-drug conjugate (BsADC).

The designation was granted for the treatment of patients with unresectable, locally advanced, or metastatic non-small cell lung cancer (NSCLC) with an epidermal growth factor receptor (EGFR) exon 19 deletion or exon 21 L858R mutation, whose disease has progressed on or after therapy with an EGFR tyrosine kinase inhibitor (TKI).

“We are excited to receive this Fast Track designation from the FDA, underscoring the promise of AVZO-1418, especially for patients with EGFR-Mutated TKI-Pretreated NSCLC,” said Mohammad Hirmand, M.D., Co-founder and Chief Medical Officer of Avenzo Therapeutics. “This designation has the potential to help expedite the development of AVZO-1418, which we continue to rapidly advance in Phase 1.”

AVZO-1418 is currently being studied in a Phase 1/2 first-in-human, open-label clinical study designed to assess the safety, tolerability, and preliminary clinical activity of AVZO-1418 as a single agent and in combination therapy in patients with advanced solid tumors.
