ArriVent BioPharma Reports Full Year 2025 Financial Results
NEWTOWN SQUARE, PA, March 5, 2026 (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 year ended December 31, 2025, and highlighted recent Company progress.
"We are advancing firmonertinib toward potential registration, supported by two pivotal programs targeting uncommon EGFR mutations in non-small cell lung cancer (NSCLC), a high unmet need with limited treatment options," said Bing Yao, CEO of ArriVent. "Our robust clinical data, including CNS activity, underscores the potential of firmonertinib to become a chemotherapy-free standard of care. We look forward to topline pivotal data for firmonertinib monotherapy in frontline EGFR exon 20 insertion mutant NSCLC expected in mid-2026. This is an event driven study, so we plan to continue sharpening our timeline as we look forward to sharing our data."
Dr. Yao continued, "Our antibody-drug conjugate (ADC) portfolio is also gaining momentum, led by ARR-217, a CDH17-targeted ADC currently in an ongoing Phase 1 trial, with best-in-class potential in gastrointestinal cancers. We expect additional ADC candidates to advance toward the clinic, broadening our pipeline beyond lung cancer into multiple additional solid tumor indications. Backed by a strong balance sheet and a projected cash runway into 3Q 2027, we are well positioned to deliver on our near-term catalysts."
Recent and Full Year 2025 Highlights
2025 Financial Results
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.
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; NCT07185997).
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 C-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.
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 (NCT05607550). 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. Secondary 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.
ALPACCA is a global, pivotal 2 arm Phase 3 clinical trial of firmonertinib in first-line non-squamous locally advanced or metastatic NSCLC patients with PACC mutations being conducted jointly with our partner Allist (NCT07185997). The ALPACCA trial is evaluating firmonertinib 240 mg once daily versus investigator's choice of osimertinib or afatinib in first-line patients with EGFR PACC mutant NSCLC. The 240 mg dose of firmonertinib was selected for pivotal development based on compelling data showing a 16-month median PFS and a confirmed 68% ORR by BICR in the FURTHER trial (NCT05364073). The primary endpoints of this study are ORR and PFS by BICR per RECIST.
