"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.

"This quarter marks an important milestone for Nkarta as we advance the NKX019 clinical program to treat autoimmune diseases," said Paul J. Hastings, Chief Executive Officer of Nkarta. "Following productive engagement with the FDA, we streamlined enrollment across our Ntrust-1 and Ntrust-2 clinical trials under a combined iDSMB, which has authorized initiation of the second dose-escalation cohort. This unified approach, combined with the ability to dose multiple patients simultaneously at each dose level and the removal of a patient-by-patient stagger, strengthens the efficiency of our trial enrollment and underscores the consistency of NKX019’s emerging safety profile.

"With the modification of our lymphodepletion regimen to include both fludarabine and cyclophosphamide prior to treatment with NKX019, we are now seeing complete B-cell depletion in all patients treated to date, compared with partial B-cell depletion observed with patients receiving cyclophosphamide alone. Now that our study design modifications have been cleared by the FDA and institutional review boards, we’re enrolling patients with the new regimen at the higher dose.

"We plan to present data with our investigators at a medical conference in 2026. In the interim, we remain focused on disciplined clinical execution. With a strong balance sheet projected to fund operations into 2029, we are now poised to meaningfully advance our clinical program in this challenging capital environment."

NKX019 Clinical Program Progress and Upcoming Milestones

•
Following engagement with the U.S. Food and Drug Administration, the patient-by-patient stagger was eliminated, accelerating the ability to dose escalate
•
Protocol amendments now allow for simultaneous dosing of multiple participants in parallel within each dose cohort.
•
Ntrust-1 and Ntrust-2 enrollment process was streamlined to permit data from both studies to be utilized by a combined, iDSMB to inform dose escalation decisions.
•
After unanimous clearance from the combined iDSMB, enrollment has begun in the second dose-escalation cohort.
•
NKX019 clinical programs in autoimmune diseases continue to enroll patients. This includes Ntrust-1, Ntrust-2, and two investigator-sponsored trials.

About the Ntrust℠ Clinical Trials in Autoimmune Disease

Ntrust-1 (NCT06557265) and Ntrust-2 (NCT06733935) are multi-center, open label, dose escalation clinical trials that build on academic studies of durable, drug-free remissions in patients with autoimmune disease after CD19-targeted cell therapy. Both trials will assess the safety of NKX019 in people living with autoimmune diseases as well as its ability to enable durable remissions via a "reset" of the immune system through the elimination of pathogenic B cells.

The Ntrust trials are enrolling up to 12 patients per dose level per disease indication across lupus nephritis, primary membranous nephropathy, systemic sclerosis, idiopathic inflammatory myopathy, and ANCA-associated vasculitis.

In both studies, patients now receive a three-dose cycle of NKX019 on Days 0, 3, and 7 following lymphodepletion with fludarabine and cyclophosphamide or cyclophosphamide alone, if they have significant cytopenia at baseline. Leveraging the engineering of NKX019, no patients in either trial will receive supplemental cytokines or antibody-based therapeutics. This approach is designed to evaluate the single-agent activity of NKX019 and facilitate a more rapid path to regulatory approval. Patients in Ntrust-1 may also receive additional cycles, if necessary, to restore response or enable a deeper response.

About the Investigator-Sponsored Clinical Trial of NKX019 for Generalized Myasthenia Gravis
The single-arm, open-label Phase 1 investigator-sponsored clinical trial is designed to enroll patients with generalized myasthenia gravis and will evaluate safety and clinical outcomes. Translational and biomarker studies, including autoantibodies, cytokine profiles and pharmacokinetics are planned. Patients receive 3 doses of NKX019 following lymphodepletion. The clinical trial is being co-led by Ali A. Habib, M.D., Clinical Professor of Neurology at the University of California, Irvine, and other investigators.

About the Investigator-Sponsored Clinical Trial of NKX019 for Systemic Lupus Erythematosus

The single-center, single-arm, open-label Phase 1 investigator-sponsored clinical trial (NCT06518668) is designed to enroll up to 6 patients with systemic lupus erythematosus, regardless of renal involvement, and will evaluate safety and clinical outcomes in a potentially different population than Ntrust-1. Translational and biomarker studies, including autoantibodies, cytokine profiles and pharmacokinetics are planned. Patients receive 3 doses of NKX019 following lymphodepletion. The clinical trial is being led by Anca D. Askanase, M.D., M.P.H., Director, Lupus Center at Columbia University Irving Medical Center and the Director of Rheumatology Clinical Trials.

About NKX019

NKX019 is an allogeneic, cryopreserved, off-the-shelf immunotherapy candidate that uses natural killer (NK) cells derived from the peripheral blood of healthy adult donors. It is engineered with a humanized CD19-directed chimeric antigen receptor (CAR) for enhanced cell targeting and a proprietary, membrane-bound form of interleukin-15 (IL-15) for greater persistence and activity without exogenous cytokine support. CD19 is a biomarker for normal B cells as well as those implicated in autoimmune disease. Nkarta is evaluating NKX019 in multiple autoimmune conditions.
