| Item 1.01 | Entry into a Material Definitive Agreement. |
On August 11, 2026, ArriVent BioPharma, Inc. (the “Company”) entered into a Collaboration and License Agreement (the “Allist License Agreement”) with Shanghai Allist Pharmaceuticals Co., Ltd. (“Allist”), a pharmaceutical company incorporated under the laws of China. Pursuant to the Allist License Agreement, the Company granted Allist an exclusive, sublicensable (through multiple tiers), royalty-bearing license under certain intellectual property owned or controlled by the Company to research, develop, manufacture, and commercialize ARR-002, the Company’s MUC16/NaPi2b-targeted antibody-drug conjugate, and products containing ARR-002, for the diagnosis, prophylaxis and treatment of diseases and conditions in Greater China, which includes the People’s Republic of China, Hong Kong, Macau, and Taiwan (the “Licensed Territory”), subject to the Company’s retained right to manufacture ARR-002 in the Licensed Territory. The Company retains all rights to ARR-002 outside the Licensed Territory, including all development and commercialization rights.
The Allist License Agreement establishes a collaboration committee to oversee and coordinate the joint global development of ARR-002. The Company is responsible for supplying ARR-002 for the start of the initial joint global clinical study and Allist is responsible for development and commercialization of ARR-002 in the Licensed Territory.
Under the Allist License Agreement, the Company may be entitled to receive payments totaling as much as $80.6 million, comprised of a one-time upfront payment and additional payments upon achievement of certain defined development, regulatory, and sales milestones, and tiered royalties in the mid-single digit to low double-digit percentages on annual net sales of licensed products in the Licensed Territory. Allist is obligated to pay royalties to the Company on a product-by-product and country-by-country basis until the latest of: (i) expiration of certain patent claims; (ii) expiration of applicable regulatory-based exclusivity or (iii) a certain number of years following the first commercial sale (the “Royalty Term”). The royalty rate is subject to specified reductions on a product-by-product and country-by-country basis under specified circumstances.
Unless earlier terminated, the Allist License Agreement will expire on the expiration of the last to expire Royalty Term. Allist may, for certain uncured material breaches by the Company, in lieu of termination, elect to keep the Allist License Agreement in force and reduce Allist’s subsequent royalty payment obligations to the Company by amounts specified in the Allist License Agreement.
The foregoing description of the Allist License Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Allist License Agreement, a copy of which will be filed as an exhibit to the Company’s Quarterly Report on Form 10-Q for the quarter ending September 30, 2026.

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; 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 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 (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.
About ALPACCA
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.
About ARR-217
ARR-217 (also known as MRG007) is a cadherin-17 (CDH17) targeted ADC, with a glycan-linked, exatecan-based antibody drug conjugate. CDH17 is a membranous cell adhesion molecule and is frequently overexpressed in colorectal cancer (CRC) and several other gastrointestinal (GI) cancers, with limited expression in normal intestinal tissue and pancreatic duct. The differential expression profile in tumor versus normal tissue makes it an attractive target for antibody-drug conjugate (ADC) in GI cancers, particularly CRC. ARR-217 is currently being evaluated in a multi-center, phase I study to evaluate the safety, tolerability, efficacy, and pharmacokinetics in patients with unresectable locally advanced or metastatic solid tumors (NCT07066657).
About ARR-002
ARR-002 (also known as AV-P138-ADC) is a first-in-class, Mucin-16 (MUC16) and sodium-dependent phosphate transport protein 2b (NaPi2b) dual-target, tetravalent (2+2 format) ADC, with site-specific conjugation to vcMMAE at a drug-to-antibody ratio (DAR) of 4. Both these cell surface antigens are expressed in solid tumors including ovarian and endometrial cancers with limited expression in normal tissues, making them ideal co-targets.
