Rice as Chief Commercial OfficerCash and investments of $305.4 million as of September 30, 2025 expected to fund operations into mid-2027 NEWTOWN SQUARE, Pa., Nov. 10, 2025 (GLOBE NEWSWIRE) -- ArriVent BioPharma, Inc. (“Company” or “ArriVent”) (Nasdaq: “AVBP”), a clinical-stage company dedicated to accelerating the global development of innovative biopharmaceutical therapeutics, today reported financial results for the third quarter ended September 30, 2025, and highlighted recent Company progress. “Our late-stage firmonertinib program continues to make strong progress across EGFR-mutant NSCLC populations, with two global Phase 3 pivotal studies being conducted in uncommon EGFR mutant non-small cell lung cancer (NSCLC). Backed by compelling data in both PACC and exon 20 insertion mutations, firmonertinib consistently shows the potential to address significant unmet needs in these underserved patient populations,” said Bing Yao, CEO of ArriVent. “Following our strong Phase 1b findings, we are advancing to pivotal development with enrollment of the first patient in our global pivotal Phase 3 trial for PACC mutant NSCLC expected in the fourth quarter of this year. Additionally, we project topline pivotal data from our global Phase 3 trial in exon 20 insertion mutant NSCLC in early 2026, a patient population for which firmonertinib received FDA Breakthrough Therapy Designation.” Dr. Yao continued, “Our antibody-drug conjugate (ADC) portfolio is also advancing with our lead candidate ARR-217, a CDH17-targeted ADC with best-in-class potential for the treatment of gastrointestinal cancers, in an ongoing Phase 1 trial. We expect additional ADC programs to progress toward the clinic, expanding our ADC portfolio across multiple solid tumor indications. With a strong balance sheet and projected cash runway into mid-2027, we believe we are well-positioned to deliver on multiple near-term catalysts.” Third Quarter 2025 and Recent Highlights Firmonertinib Final Phase 1b data in EGFR PACC mutant NSCLC. In September 2025, ArriVent presented final proof-of-concept data from the randomized global Phase 1b FURTHER trial for first-line firmonertinib monotherapy in patients with NSCLC harboring EGFR PACC mutations at the 2025 World Conference on Lung Cancer (WCLC). Firmonertinib demonstrated clinically meaningful progression free survival, central nervous system (CNS) complete responses, and a manageable safety profile consistent with previous trials in what we believe to be the first clinical dataset testing an EGFR inhibitor in a prospectively defined population of EGFR PACC mutant NSCLC. Pipeline Clinical advancement of ADC lead candidate ARR-217 (MRG007). Phase 1 dose escalation continues in the Phase 1 study for ARR-217, a CDH17-targeted ADC, in gastrointestinal malignancies with our partner, Lepu Biopharma Co., Ltd. In addition, ArriVent has received FDA IND clearance for ARR-217. Upcoming Milestones First-line EGFR PACC registrational study. Enrollment of first patient in the randomized, global pivotal ALPACCA Phase 3 study for first-line firmonertinib monotherapy in EGFR PACC mutant NSCLC expected in Q4 2025. Firmonertinib Pivotal EGFR exon 20 insertion data. Top-line firmonertinib monotherapy data from the global pivotal FURVENT Phase 3 (NCT05607550) study for first-line EGFR exon 20 insertion mutant NSCLC is projected to be in early 2026. Corporate Appointed Brent S. Rice as Chief Commercial Officer. In September 2025, ArriVent appointed Brent S. Rice as Chief Commercial Officer who joins ArriVent with over 25 years of U.S. and global commercial experience in the biotechnology and pharmaceutical industry.

About ArriVent ArriVent is a clinical-stage biopharmaceutical company dedicated to the identification, development, and commercialization of differentiated medicines to address the unmet medical needs of patients with cancers. ArriVent seeks to utilize its team’s deep drug development experience to maximize the potential of its lead development candidate, firmonertinib, and advance a pipeline of novel therapeutics, such as next-generation antibody drug conjugates, through approval and commercialization. About Firmonertinib Firmonertinib is an oral, highly brain-penetrant, and broadly active mutation-selective epidermal growth factor receptor (EGFR) inhibitor active against both classical and uncommon EGFR mutations, including PACC and exon 20 insertion mutations. In March 2021, firmonertinib was approved in China for first-line advanced non-small-cell lung cancer (NSCLC) with EGFR exon 19 deletion or L858R mutations and for patients with previously treated locally advanced or metastatic NSCLC with EGFR T790M mutation, otherwise known as EGFR classical mutations. Firmonertinib was granted U.S. Food and Drug Administration (FDA) Breakthrough Therapy Designation for the treatment of patients with previously untreated locally advanced or metastatic non-squamous NSCLC with EGFR exon 20 insertion mutations. Firmonertinib was also granted U.S. FDA Orphan Drug Designation for the treatment of NSCLC with EGFR mutations or human epidermal growth factor receptor 2 (HER2) mutations or HER4 mutations. Firmonertinib is currently being studied in a global Phase 3 trial for first-line NSCLC patients with EGFR exon 20 insertion mutations (FURVENT; NCT05607550) and in a global Phase 3 study in first line NSCLC patients with EGFR PACC mutations (ALPACCA). In addition, firmonertinib is also being studied in a clinical combination study targeting advanced or metastatic NSCLC patients with EGFR classical mutations, in partnership with Beijing InnoCare Pharma Tech Co., Ltd. About EGFR mutant NSCLC Globally, lung cancer is the leading cause of cancer-related deaths among men and women. NSCLC is the predominant subtype of lung cancer, accounting for approximately 85% of all cases. Mutational activation of the EGFR is a frequent and early event in the development of NSCLC. EGFR mutations are divided into classical and uncommon. EGFR exon 20 insertion mutations are a group of uncommon EGFR mutations and constitute approximately 9% of all EGFR mutations. PACC mutations are another group of uncommon EGFR mutations and represent approximately 12% of all EGFR mutations. Patients with NSCLC whose tumors harbor uncommon EGFR mutations have significantly lower life expectancy with available therapies and represent an area of unmet medical need. About EGFR PACC mutations P-loop and αC-helix compressing (PACC) EGFR mutations are a distinct set of approximately 70 mostly missense activating mutations within the kinase domain of EGFR. They are similar to Exon 20 insertion mutations in narrowing the drug binding pocket to affect tyrosine kinase inhibitor activity. PACC mutations are diagnosed through commercially available NGS and most PCR tests. Patients with PACC mutations have limited treatment options, and there is no broadly utilized standard of care treatment for first-line PACC mutant patients. About FURVENT FURVENT is a global, pivotal, 3 arm Phase 3 clinical trial of firmonertinib in first-line non-squamous locally advanced or metastatic NSCLC patients with exon 20 insertion mutations being conducted jointly with our partner Allist. The FURVENT clinical trial is designed to assess the safety and efficacy of firmonertinib administered at either 160 mg or 240 mg, once-daily with each dose being compared to platinum-based chemotherapy with pemetrexed, the current first-line standard of care. The primary endpoint of this study is PFS by BICR per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1. Seconday endpoints in patients with brain metastases at baseline include brain-specific CNS overall response rate (CNS-ORR) and CNS-PFS by modified RECIST (mRECIST). The study enrolled 398 patients globally, including from sites in the United States, Europe and certain Asian countries including Japan and China. An interim analysis for this study has not been performed and there is no plan to perform such analysis given the expected timing of top-line data.
