• Company progresses the development of furmonertinib with a data readout planned for 2024
• Furmonertinib granted Breakthrough Therapy Designation by the U.S. Food and Drug Administration

NEWTOWN SQUARE, Pa., March 28, 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 full year ended December 31, 2023, and highlighted recent company progress.

“The fourth quarter was transformational for ArriVent, as we positioned our company for the successful IPO that we executed in January of this year and continued our strong progress with furmonertinib, which received Breakthrough Therapy Designation from the FDA,” said Bing Yao, Chairman and Chief Executive Officer of ArriVent. “Our company is well capitalized, with cash runway into 2026, and we have an experienced management team dedicated to strong pipeline execution. This year we look forward to providing an update on our Phase 1b FURTHER trial that includes EGFR mutant NSCLC patients with PACC mutations and advancing our Phase 3 FURVENT trial in frontline NSCLC with EGFR exon 20 insertion mutations as we continue our mission to identify and develop potentially transformative medicines to address the unmet medical needs of patients with cancer.”

2023 Highlights

Furmonertinib

• Announced clinical development collaboration with InnoCare Pharma. In July 2023, ArriVent and Beijing InnoCare Pharma Tech Co., Ltd. (“InnoCare Pharma”) announced a clinical development collaboration investigating a novel Src Homology 2 domain containing protein tyrosine phosphatase (“SHP2”) allosteric inhibitor, ICP-189, in combination with furmonertinib in patients with advanced non-small cell lung cancer (“NSCLC”).
  
  
• Presented interim results from the Phase 1b, randomized, open-label, multi-center clinical study (FAVOUR), evaluating the efficacy and safety of furmonertinib in patients with locally advanced or metastatic NSCLC with epidermal growth factor receptor (“EGFR”) exon 20 insertion mutations. In September 2023, ArriVent and its partner, Shanghai Allist Pharmaceuticals Company, Ltd. ("Allist”), presented interim Phase 1b results at the World Conference on Lung Cancer.
  
  
• U.S. Food and Drug Administration (FDA) granted Breakthrough Therapy Designation for furmonertinib for first-line treatment of advanced or metastatic NSCLC with EGFR exon 20 insertion mutations. In October 2023, ArriVent announced that the FDA granted Breakthrough Therapy Designation for furmonertinib for the treatment of patients with previously untreated, locally advanced or metastatic non-squamous NSCLC with EGFR exon 20 insertion mutations. The pivotal Phase 3 FURVENT trial (NCT05607550) of furmonertinib for the treatment of first-line NSCLC with EGFR exon 20 insertion mutations is currently enrolling patients globally.

Upcoming Milestones

• Proof-of-concept data expected in 2024. Furmonertinib is currently being studied in the Phase 1b FURTHER (NCT05364073) study in patients with NSCLC EGFR P-loop alpha-c helix compressing (“PACC”) mutations, which has been fully enrolled, with proof-of-concept data expected in 2024.
  
  
• Presentation of preclinical data for furmonertinib at the 2024 American Association for Cancer Research (“AACR”) Annual Meeting. ArriVent will present preclinical data evaluating furmonertinib in NSCLC with EGFR exon 20 insertion mutations and PACC mutations at the AACR Annual Meeting, being held April 5-10. The preclinical study found furmonertinib is similarly active against both PACC and exon 20 insertion mutations.
  
  
• Initiation of the clinical combination study with furmonertinib and ICP-189, a SHP2 inhibitor. ArriVent and its partner, InnoCare Pharma, dosed its first patient of this clinical combination study targeting EGFR classical mutations in March 2024.
  
  
• Selection of antibody drug conjugate (ADC) development candidate. ArriVent and its partner, Aarvik Therapeutics, Inc (“Aarvik”), continue to make progress on selecting an ADC development candidate, and expect to complete selection in late 2024 or early 2025.

Corporate Updates

• Completed a successful IPO. In January 2024, ArriVent successfully raised $201 million in gross proceeds before deducting underwriting discounts, commissions, and offering expenses.
  
  
• Strengthened board and executive team leadership. In September 2023, ArriVent appointed Chris Nolet to its Board of Directors. Mr. Nolet has extensive leadership experience as an audit partner, business advisor and independent board director in the life sciences industry, and serves on the boards of public companies Revance Therapeutics and Jasper Therapeutics. In January 2024, ArriVent appointed Winston Kung as Chief Financial Officer and Treasurer, bringing over 20 years of extensive leadership experience, most recently as Chief Financial Officer and Chief Operating Officer at PMV Pharmaceuticals.

Fiscal Year 2023 Financial Results

• Research and development expenses were $64.9 million and $30.4 million for the years ended December 31, 2023 and 2022, respectively. The increase in expense was primarily due to increased clinical spending on trials related to furmonertinib.
  
  
• General and administrative expenses were $9.7 million and $6.5 million for the years ended December 31, 2023 and 2022, respectively. The increase was primarily due to increased external costs related to preparing for and operating as a public company, as well as increased personnel costs to support these activities.
  
  
• Net loss was $69.3 million and $37.0 million for the years ended December 31, 2023 and 2022, respectively.
  
  
• As of December 31, 2023, the company had cash, cash equivalents and marketable securities of $150.4 million, which, with the proceeds from our IPO in January 2024, is expected to fund operations into 2026.
