FLORHAM PARK, N.J., Aug. 13, 2025 (GLOBE NEWSWIRE) -- BeyondSpring Inc. (NASDAQ: BYSI), a clinical-stage company developing transformative therapies for the treatment of cancer and other diseases, today reported Q2 2025 financial results alongside clinical and corporate milestones.

“At the heart of BeyondSpring’s pipeline is Plinabulin, a first-in-class agent potentially redefining cancer treatment by harnessing the body’s own immune system,” said Dr. Lan Huang, Co-Founder, Chair, and CEO. “Plinabulin’s ability to mature dendritic cells in human studies, bridges innate and adaptive immunity, offering potentially new hope to the 60% of NSCLC patients whose disease progresses after checkpoint inhibitor therapy. In our global Phase 3 trial (Dublin-3, published in LANCET Respiratory Medicine), plinabulin and docetaxel combination compared to standard of care docetaxel alone, delivered durable survival benefits alongside reduced chemotherapy-induced neutropenia — a combination with strong potential to influence standards of care.”

Dr. Huang added, “BeyondSpring’s impact extends beyond Plinabulin. As SEED Therapeutics’ (“SEED”) founding shareholder, BeyondSpring, along with cornerstone investors and research collaborators Eli Lilly and Eisai, has supported SEED’s pioneering work in targeted protein degradation. SEED’s oral RBM39 molecular glue degrader, ST-01156, recently received FDA clearance to enter clinical trials, targeting aggressive cancers including Ewing Sarcoma and KRAS-driven tumors, with U.S. leading cancer institutions driving development forward.”

Key Milestones:

• ASCO 2025 Presentation on Plinabulin Effect in Re-sensitizing Tumors Progressed on Prior PD-1/L1 Inhibitors: New data from a phase 2 study evaluating pembrolizumab in combination with Plinabulin and docetaxel in metastatic NSCLC patients who progressed on prior PD-1/L1 inhibitors, showed encouraging efficacy and safety data. The combination demonstrated median progression-free survival (PFS) of 6.8 months, confirmed objective response rate (ORR) of 18.2%, duration of response (DOR) of 7.2 months, disease control rate (DCR) of 77%, and overall survival (OS) of 78% at 15 months.
  
  
• Med (Cell Press) Publication on Plinabulin Mechanism in Dendritic Cell Maturation in Human Studies with MD Anderson Collaboration: Plinabulin, when used in combination with radiation and a checkpoint inhibitor, rapidly induces dendritic cell (DC) maturation in multiple cancer types in patients who failed prior immunotherapy. The combination was associated with tumor responses across eight types of cancer in patients previously refractory to immune checkpoint inhibitor (ICI) therapy, including NSCLC, head and neck cancer, and Hodgkin lymphoma. The study reported an ORR of 23% and a DCR of 54%. Importantly, the research identified a potential predictive biomarker, baseline GEF-H1 immune signature, which may support patient selection and clinical response prediction.
  
  
• SEED’s IND Clearance from US FDA for Lead Oncology Asset RBM39 Degrader ST-01156: The U.S. Food and Drug Administration (FDA) cleared SEED’s Investigational New Drug (IND) application for ST-01156, a brain penetrant, novel orally administered molecular glue degrader targeting RBM39.
  
  
• AACR 2025 Presentation on SEED’s Two Key Preclinical Advancements: 1) ST-01156 demonstrated complete tumor regression in Ewing Sarcoma models, and its corresponding mechanism, and 2) a dual-degrader approach showed promising activity in KRAS G12D target degradation and KRAS G12D-driven tumors.
  
  
• SEED Strengthened Leadership: Dr. Bill Desmarais, Ph.D., MBA, joins SEED Therapeutics as CFO and Chief Business Officer, bringing two decades of leadership in finance, business development, and strategic expertise in biopharma and biotech.
  
  

Second Quarter Financial Results¹
Continuing operations:

• Research and development (R&D) expenses were $1.0 million for the quarter ended June 30, 2025 compared to $0.8 million for the quarter ended June 30, 2024. The $0.2 million increase was primarily due to higher professional service fees in regulatory and CMC activities as well as increased costs for Plinabulin research.
• General and administrative (G&A) expenses were $0.9 million for the quarter ended June 30, 2025, compared to $1.8 million for the quarter ended June 30, 2024. The $0.9 million decrease was primarily due to lower professional service costs in consulting for business development initiatives, and lower salary expenses driven by decrease in administrative headcount. 
• Net loss: $1.9 million for the quarter ended June 2025, compared to $2.7 million for the quarter ended June 2024
• Cash and cash equivalents: $9.5 million as of June 30, 2025, compared to $2.9 million as of December 2024

Discontinued operations:

• Net loss: $2.8 million for the quarter ended June 2025, compared to $1.4 million for the quarter ended June 2024
• Current assets: $15.7 million as of June 2025, compared to $25.3 million as of December 2024

Year to Date Financial Results¹
Continuing Operations:

• Research and development (R&D) expenses were $1.9 million for the six months ended June 30, 2025 compared to $1.6 million for the six months ended June 30, 2024. The $0.3 million increase was primarily due to higher professional service fees in regulatory and CMC activities as well as increased costs for Plinabulin research.
• General and administrative (G&A) expenses were $2.7 million for the six months ended June 30, 2025, compared to $3.1 million for the six months ended June 30, 2024. The $0.4 million decrease was primarily due to lower salary expenses resulting from decrease in administrative headcount, and lower company overhead expenses mainly due to decrease in investor relations services and D&O insurance related costs. 
• Net loss: $4.5 million for the six months ended June 2025, compared to $4.7 million for the six months ended June 2024
  
  

Discontinued operations:

• Net income (loss): $1 million for the six months ended June 2025, compared to ($2.6 million) for the six months ended June 2024
