Full Press Release Details
FLORHAM PARK, N.J., Jan. 28, 2025 (GLOBE NEWSWIRE) --BeyondSpring Inc.(NASDAQ: BYSI) (“BeyondSpring” or the “Company”), a global clinical-stage biopharmaceutical company developing innovative cancer therapies, today announced that it has entered into definitive agreements to sell a portion of its Series A-1 Preferred Shares ofSEED Therapeutics Inc.(“SEED”), a biotechnology company focused on Targeted Protein Degradation (TPD) technology and a subsidiary of the Company, for gross proceeds of approximately $35.4 million. Upon completion of the transactions, BeyondSpring, together with SEED Technology Limited, a majority-owned indirect subsidiary of the Company, is expected to retain approximately 14.4% of SEED’s outstanding shares.
Strategic Background and RationaleSince 2016, BeyondSpring has been at the forefront of TPD innovation, incubating its proprietary TPD technology internally and co-founding SEED with Eli Lilly and Company in 2020. Through this pioneering sponsorship, SEED has grown into a leader in TPD, a revolutionary drug discovery approach targeting previously undruggable proteins. SEED has developed a robust pipeline of therapies in oncology and neurodegeneration, leveraging its proprietary molecular glue-based platform. Research collaborations with Eli Lilly and Company, and Eisai Co. Ltd. (“Eisai”) further validate its leadership in TPD.
The recent Series A-3 financing led by Eisai, at a pre-money valuation of $100 million, underscores SEED’s innovation and market potential. The transactions announced today will enable BeyondSpring to unlock value while retaining a meaningful ownership stake in SEED. The $35.4 million in proceeds will advance BeyondSpring’s late-stage clinical trials of its lead asset, Plinabulin, ensuring critical resources without diluting shareholder equity.
Plinabulin: A First-in-Class Agent with Broad PotentialPlinabulin is a first-in-class anti-cancer agent which has been used in over 700 cancer patients with good tolerability. It is a differentiated tubulin binder, which releases immune defense protein GEF-H1, leading to dendritic cell maturation that drives both direct anti-cancer activity and immune system activation1,2. It has demonstrated durable anti-cancer benefits across multiple clinical studies and addresses significant unmet medical needs in oncology:
Dr. Trevor Feinstein, MD, a lead principal investigator of the DUBLIN-3 Study at Piedmont Cancer Center, Atlanta, highlighted the critical need addressed by Plinabulin:“There is a poor prognosis for NSCLC patients without targetable alterations whose disease has progressed on platinum-based therapies and immune checkpoint inhibitors. Over 60% of patients progress on PD-1/PD-L1 inhibitors in NSCLC4. Unfortunately, multiple high-profile phase 3 studies failed to show overall survival benefit in this hard-to-treat population compared to standard of care docetaxel, a drug approved over 20 years ago. The data from the DUBLIN-3 Study demonstrates that the addition and proper sequencing of Plinabulin to docetaxel has a favorable benefit/risk ratio compared with docetaxel alone and may have broad utility. In addition, current ongoing 303 and 302 Studies are targeting additional severe unmet medical needs, which Plinabulin’s mechanism of action can help address.”
“With this capital, BeyondSpring is strategically positioned to advance our 303 and 302 studies in Plinabulin combination with immune checkpoint inhibitors to registrational trials and explore business development partnerships to bring Plinabulin to cancer patients with limited treatment options,”said Dr. Lan Huang, Co-Founder, Chairman, and CEO of BeyondSpring.“At the same time, retaining a substantial stake in SEED Therapeutics ensures that we remain part of its continued success in revolutionizing drug discovery.”
This press release shall not constitute an offer to sell or a solicitation of an offer to buy, nor shall there be any sale of these securities in any state or jurisdiction in which such an offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction.

About PlinabulinPlinabulin is a novel first-in-class dendritic cell maturation agent with durable anti-cancer benefit observed across multiple clinical studies. As a reversible binder at a distinct tubulin pocket, Plinabulin does not change tubulin dynamics or antagonize tubulin stabilizing agents, such as docetaxel, which contributes to its differentiated activity and tolerability compared to other tubulin binders. In addition, Plinabulin significantly reduces chemotherapy induced neutropenia and could thereby increase docetaxel tolerability. Over 700 patients have been treated with Plinabulin with good tolerability.
About DUBLIN-3 (103) StudyDUBLIN-3 is a multicenter, single-blinded (patient) and randomized, phase 3 trial in 58 medical centers (US, China, and Australia, n=549). Only patients with EGFR wild-type NSCLC who had progressed after first-line platinum-based therapy were enrolled. Patients were randomized (1:1) to receive docetaxel (75 mg/m2) on Day 1 and either Plinabulin (30 mg/m2) or placebo on Days 1 and 8 in 21-day cycles until progression, unacceptable toxicity, withdrawal, or death. Treated patients were included in the safety analysis and ITT population in the primary efficacy analyses (NCT02504489). The primary endpoint for the study was OS, and secondary endpoints were PFS, ORR, Duration of Response (DoR), Grade 4 neutropenia and Quality of Life.
About 303 Study303 Study is an open-label, single-arm Phase 2 Study of Plinabulin plus docetaxel and pembrolizumab for previously treated patients with metastatic NSCLC and progressive disease after anti-PD-(L)1 inhibitor alone or in combination with platinum-doublet chemotherapy. This study evaluates the efficacy and safety of this triple combination and is being conducted at Peking Union Medical College Hospital, Beijing, China. The regimen includes Pembrolizumab 200 mg IV every 3 weeks (Q3W) on Day 1, Docetaxel 75 mg/m2IV Q3W on Day 1 and Plinabulin 30mg/m2IV Q3W on Day 1 in a 21-day cycle. The primary endpoint is investigator-based ORR (RECIST 1.1). The secondary endpoints include PFS, OS, DoR, and safety. The study intends to enroll 47 patients. The study is funded by Merck’s Investigator Studies Program with provision of study drug and financial support.
About 302 Study302 Study is an open-label, single-arm Phase 2 Study of Plinabulin plus etoposide + platinum and pembrolizumab in first line extended-stage SCLC. This study evaluates the efficacy and safety of this combination and is being conducted at Wuhan Union Hospital in China, with Dr. Xiaorong Dong, Deputy Director of the Oncology Research Department and Director of the Thoracic Oncology Department, as the principal investigator. Patients enrolled are receiving the following interventional treatments for the first 4 cycles: Pembrolizumab 200 mg IV every 3 weeks (Q3W) on Day 1; Etoposide 100 mg/m2IV Q3W on Days 1, 2, and 3; Carboplatin AUC 5 IV Q3W on Day 1 or Cisplatin 75 mg/m2IV Q3W on Day 1; Plinabulin 30mg/m2IV Q3W on Day 1. From cycle 5, only Pembrolizumab and Plinabulin are given on Day 1 of each cycle. The primary endpoint is the 12-month PFS rate. The study intends to enroll 45 patients. The study is funded by Merck’s Investigator Studies Program with provision of study drug and financial support.
About BeyondSpringBeyondSpringis a global clinical-stage biopharmaceutical company developing innovative therapies to improve clinical outcomes for patients with high unmet medical needs. The Company is advancing its first-in-class lead asset, Plinabulin, into late-stage clinical development as a direct anti-cancer agent in NSCLC and a variety of cancer indications. Plinabulin binds to a differentiated pocket in tubulin, distinct from other tubulin binders, and is a potent inducer of dendritic cell maturation, which activates both adaptive and innate immunity. Plinabulin and docetaxel combination demonstrated significant overall survival benefit compared to docetaxel in second- and third-line NSCLC with EGFR wild type (Lancet Respir Med 2024). In addition, Plinabulin had been shown to significantly reduce severe neutropenia in a number of clinical studies. BeyondSpring’spipelinealso includes three preclinical immuno-oncology assets.
