About this update from Beyondspring, Inc.
FLORHAM PARK, N.J., March 27, 2025 (GLOBE NEWSWIRE) -- BeyondSpring Inc. (NASDAQ: BYSI) (“BeyondSpring” or the “Company”), a global clinical-stage biopharmaceutical company developing innovative cancer therapies, today announced its financial results for the year ended December 31, 2024, and provided a business update on key clinical and corporate developments. “2024 was a pivotal year for BeyondSpring, with significant clinical progress for our first-in-class agent Plinabulin and strategic advancements for SEED Therapeutics (SEED), which BeyondSpring co-founded and owns an equity stake in. We believe these developments create value benefiting all stakeholders,” said Dr. Lan Huang, Co-Founder, Chairman, and CEO of BeyondSpring. “Plinabulin demonstrated a statistically significant survival benefit in patients with second- and third-line non-small cell lung cancer (NSCLC) (EGFR wild-type), a setting where no new therapies have been approved in over a decade. This Phase 3 data , now published in The Lancet Respiratory Medicine , strengthens our regulatory strategy as we prepare for submission to the Chinese National Medical Products Administration (NMPA) and potentially regulatory authorities in other jurisdictions.” “BeyondSpring is also advancing Plinabulin’s potential as a next-generation immuno-oncology agent, with its potent effect in dendritic cell maturation. An ongoing Phase 2 study showed that Plinabulin, in combination with a PD-1 inhibitor and docetaxel, produced promising efficacy in patients with metastatic NSCLC who had progressed on prior PD-1/PD-L1 inhibitors with good tolerability . While PD-1 and PD-L1 antibody annual sales have exceeded $50 billion, with most sales coming from lung cancer, 60% of patients across multiple cancer indications develop acquired resistance to checkpoint inhibitors, which we believe represents a significant opportunity for Plinabulin to impact the treatment landscape and create substantial value .” “SEED also made significant progress in 2024, securing a strategic research collaboration with Eisai Co., Ltd. (“Eisai”), a second global pharma partnership in addition to the Eli Lilly and Company (“Lilly”) partnership . Under this collaboration, SEED will be eligible to receive upfront payments and potential preclinical, clinical, regulatory and sales milestone payments of up to $1.5 billion, plus tiered royalties on net sales. In parallel, SEED is advancing its internal lead oncology asset, RBM39 degrader, toward clinical development. SEED’s recognition in two Nature review papers as a leader in targeted protein degradation (TPD), along with recent granting of Rare Pediatric Disease and Orphan Drug Designations by the FDA for its RBM39 degrader ST-01156, further underscore its unique platform and reinforce its leadership in this emerging field.” “With strongly anchored pipelines, key global partnerships and deliberate plans to navigate regulatory pathways, we believe BeyondSpring and SEED are well-positioned to drive transformative advancements in oncology and TPD in 2025,” Dr. Lan Huang concluded.
