ArriVent BioPharma’s Phase 3 Study on Firmonertinib: A Potential Game-Changer in NSCLC Treatment

ArriVent BioPharma, Inc. ((AVBP)) announced an update on their ongoing clinical study.

Study Overview: ArriVent BioPharma, Inc., in collaboration with Allist Pharmaceuticals, Inc., is conducting a global Phase 3 clinical study titled ‘A Global Phase 3, Double-Blind, Randomized, Controlled Multicenter Study to Assess the Efficacy and Safety of Firmonertinib Versus Placebo for Adjuvant Treatment in Participants With Stage IB – IIIB NSCLC With Uncommon Epidermal Growth Factor Receptor (EGFR) Mutations, Following Complete Surgical Resection With or Without Adjuvant Chemotherapy (FIRMOST)’. The study aims to evaluate the efficacy and safety of firmonertinib as an adjuvant treatment for patients with specific types of non-small cell lung cancer (NSCLC) who have undergone surgical resection.

Intervention/Treatment: The study tests firmonertinib, an experimental drug administered orally at 240 mg daily, against a placebo. The goal is to determine its effectiveness in preventing cancer recurrence post-surgery.

Study Design: This interventional study uses a randomized, parallel assignment model with quadruple masking (blinding of participants, care providers, investigators, and outcomes assessors). The primary purpose is treatment-focused, aiming to assess firmonertinib’s potential benefits over a placebo.

Study Timeline: The study began on May 20, 2025, with the latest update submitted on June 5, 2025. These dates mark the initiation and recent progress in the study, indicating its current recruiting status.

Market Implications: The successful development of firmonertinib could significantly impact ArriVent BioPharma’s market position, potentially boosting its stock value and investor confidence. As the study progresses, positive results could position the company favorably against competitors in the NSCLC treatment landscape.

The study is ongoing, with further details available on the ClinicalTrials portal.
