"Firmonertinib continues to advance with strong momentum toward registration, demonstrating promise across all key EGFR-mutant NSCLC populations including underrepresented and difficult to treat patient types," said Bing Yao, CEO of ArriVent. "The positive interim PACC Phase 1b data build on our clinical progress in Exon 20 insertion mutations and further validate the therapeutic potential of firmonertinib across EGFR mutations. We look forward to presenting final PACC Phase 1b data at the World Conference on Lung Cancer in September, and we anticipate enrolling the first patient in our global pivotal Phase 3 PACC study in the second half of 2025. Following completion of enrollment in our registrational Exon 20 insertion trial in Q1 2025, topline pivotal data is projected to be in early 2026."

Dr. Yao continued, "We believe our antibody-drug conjugate (ADC) pipeline is also making meaningful progress, led by ARR-217, a CDH17-targeted ADC with best-in-class potential for the treatment of gastrointestinal cancers. The first patient has been dosed, marking the first clinical entry from our ADC portfolio. Following our strengthened balance sheet and extended cash runway, we are well positioned to deliver on a series of important catalysts over the next twelve months."

Second Quarter 2025 and Recent Highlights

Firmonertinib

● Positive interim update in EGFR PACC mutant NSCLC. In June 2025, ArriVent presented updated interim Phase 1b data for first-line firmonertinib monotherapy in NSCLC patients with EGFR PACC mutations (FURTHER; NCT05364043). Firmonertinib demonstrated clinically meaningful progression free survival, 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.

● PACC clinical development plans. In June 2025, ArriVent announced the design of ALPACCA (FURMO-006), a randomized global Phase 3 study designed to evaluate first-line firmonertinib monotherapy for the treatment of PACC mutant NSCLC with potential for both accelerated and full approval.
Pipeline

● Clinical advancement of ADC lead ARR-217 (MRG007). Dosed the first patient in the Phase 1 study for ARR-217, a CDH17 targeted ADC, in gastrointestinal tumors by our partner, Lepu Biopharma Co., Ltd. ("Lepu BioPharma").
Upcoming Milestones

● Final EGFR PACC Phase 1b data. Final EGFR PACC cohort data to be presented at the WCLC in September 2025.
● 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 2H 2025.
● Firmonertinib Pivotal EGFR Exon 20 insertions data. Top-line firmonertinib monotherapy data from the global pivotal FURVENT Phase 3 (NCT05607550) study for first-line EGFR Exon 20 insertions mutant NSCLC is projected to be in early 2026.
2025 Financial Results

● As of June 30, 2025, the Company had cash and investments of $254.5 million. The cash balance as of June 30, 2025 does not include the net proceeds of $81.1 million raised in the recently completed public offering in July 2025. With the recent net proceeds in addition to our cash and investments, we expect to fund operations to mid-2027.
● Net cash used in operations was $94.1 million and $37.7 million for the six months ended June 30, 2025 and 2024, respectively. The increase in net cash used in operations in the first six months of 2025 was primarily driven by the one-time upfront payment of $40 million made to Lepu Biopharma.
● Research and development expenses were $89.0 million and $38.8 million for the six months ended June 30, 2025 and 2024, respectively. The increase in expense was primarily due to a one-time upfront payment made to Lepu Biopharma for our collaboration that began in January 2025, along with increased headcount and clinical expense related to firmonertinib.
● General and administrative expenses were $11.4 million and $7.6 million for the six months ended June 30, 2025 and 2024, respectively.
● Net loss was $95.8 million and $39.3 million for the six months ended June 30, 2025 and 2024, respectively.
