NEWTOWN SQUARE, Pa., Aug. 14, 2024 (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 second quarter ended June 30, 2024, and highlighted recent Company progress.

“We made strong progress this quarter further advancing and expanding our global oncology pipeline. At the annual WCLC we plan to present interim first-line firmonertinib monotherapy data from our FURTHER study in patients with NSCLC harboring EGFR PACC mutations, which to our knowledge, will be the first data from a prospectively designed clinical trial of an EGFR tyrosine kinase inhibitor in this patient population,” said Bing Yao, Chairman and Chief Executive Officer of ArriVent. “Earlier this quarter we also expanded our ADC portfolio with a multi-target ADC collaboration agreement with Alphamab, combining their discovery capabilities and know-how with our global drug development and commercialization expertise. Collectively, these programs are designed to deliver new targeted therapies with the potential to change the treatment paradigm for millions of patients with tough to treat cancers and high unmet needs.”

Second Quarter 2024 and Recent Highlights

Firmonertinib

• Presentation of preclinical data for firmonertinib at the 2024 AACR Annual Meeting. In April, ArriVent presented preclinical data evaluating firmonertinib in NSCLC with EGFR exon 20 insertion mutations and PACC mutations at the American Association for Cancer Research (AACR) Annual Meeting. In the preclinical study, firmonertinib, a highly brain penetrant mutant-selective EGFR inhibitor, was observed to be broadly active across a wide range of uncommon mutations including PACC and exon 20 insertion mutations.

Pipeline

• Entered into an ADC collaboration agreement with Alphamab. In June, ArriVent entered into a collaboration agreement with Jiangsu Alphamab Biopharmaceuticals Co., Ltd. (Alphamab), a wholly owned subsidiary of Alphamab Oncology, to discover, develop and commercialize novel ADCs for the treatment of cancers.

Upcoming Milestones

• Proof-of-concept data to be presented as late-breaker at 2024 WCLC. In August, ArriVent announced that interim FURTHER Phase 1b clinical data for first-line firmonertinib monotherapy in patients with NSCLC and EGFR PACC mutations will be presented as part of a presidential symposium at the 2024 WCLC on September 9, 2024. ArriVent plans to host a virtual webinar event on the Phase 1b firmonertinib EGFR PACC data on September 9, 2024 at 4:30pm ET in conjunction with 2024 WCLC. Please register for the event here.
• Selection of next-generation ADC candidate. ArriVent and its partner, Aarvik Therapeutics, Inc., continue to make progress on selecting a multi-target multivalent ADC clinical candidate, and expect to complete selection in late 2024 or early 2025.
• Top-line pivotal Phase 3 data in 2025. Firmonertinib is currently being studied as a monotherapy in the pivotal, global Phase 3 FURVENT trial (NCT05607550) evaluating firmonertinib in previously untreated NSCLC patients whose tumors contain EGFR exon 20 insertion mutations with topline data expected in 2025.

Corporate Updates

• Strengthened board leadership. In May 2024, ArriVent appointed John Hohneker, M.D. to its Board of Directors. Dr. Hohneker brings over 30 years of experience in biopharmaceutical leadership and drug development, previously serving as President and CEO of Anokion SA and holding leadership roles at Forma Therapeutics and Novartis AG. He currently serves on the boards of public companies Carisma Therapeutics and Curis, and private companies Sonata Therapeutics and Trishula Therapeutics. Dr. Hohneker serves on ArriVent’s Nominating and Corporate Governance Committee and Compensation Committee. In April 2024, ArriVent appointed Kristine Peterson to its Board of Directors. Ms. Peterson has served on the boards of multiple public biopharmaceutical companies, including Immunocore and ImmunoGen (recently acquired by Abbvie), and brings over 30 years of industry leadership experience having previously served as CEO of Valeritas and Company Group Chair of Johnson and Johnson for their worldwide biotech and oncology groups. Ms. Peterson serves on ArriVent’s Compensation Committee.

Second Quarter 2024 Financial Results

• As of June 30, 2024, the Company had cash and cash equivalents of $298.7 million, which is expected to fund operations into 2026. Net cash used in operations was $37.7 million and $25.5 million for the six months ended June 30, 2024 and 2023, respectively.
• Research and development expenses were $38.8 million and $30.6 million for the six months ended June 30, 2024 and 2023, respectively. The increase in expense was primarily due to increased headcount and clinical expense related to firmonertinib.
• General and administrative expenses were $7.6 million and $4.2 million for the six months ended June 30, 2024 and 2023, respectively. The increase in expense was primarily due to expenses related to expanding the infrastructure necessary for operating as a public company.
• Net loss was $39.3 million and $33.7 million for the six months ended June 30, 2024 and 2023, respectively.

About Firmonertinib

Firmonertinib (formerly furmonertinib) 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 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. Food and Drug Administration Orphan Drug Designation for the treatment of non-small cell lung cancer with epidermal growth factor receptor (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 1b study, which includes a cohort evaluating firmonertinib in patients with EGFR PACC mutations (FURTHER; NCT05364043). 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.
