Presentation at IO 360° conference showed early efficacy for Plinabulin combinations in metastatic NSCLC and Hodgkin lymphoma resistant to PD‑1/L1 therapySEED’s first‑in‑class RBM39 degrader, reported at AACR 2025 for its total tumor regression data in mechanism targeted cancer indication-Ewing Sarcoma, remains on track for IND filing mid‑2025

FLORHAM PARK, N.J., May  12, 2025  (GLOBE NEWSWIRE) -- BeyondSpring Inc. (NASDAQ: BYSI), a clinical‑stage global biopharmaceutical company focused on developing cancer therapeutics, today announced its unaudited financial results for the quarter ended March 31, 2025, and provided a corporate update.

“Plinabulin has now been administered to more than 700 patients with a favorable safety profile. By promoting dendritic‑cell maturation, it offers a potential option for the approximately 60 percent of cancer patients who progress on PD‑1/L1 inhibitors,” said Dr. Lan Huang, Co‑Founder, Chair, and Chief Executive Officer of BeyondSpring. “Early readouts in metastatic NSCLC and Hodgkin lymphoma who failed PD-1/L1 inhibitors showed durable responses that deserve further evaluation.”

Dr. Huang added, “Within SEED, our RBM39 molecular‑glue degrader achieved complete tumor regression in mechanism-targeted Ewing sarcoma models and is on track for an IND submission mid‑year. We are also pursuing additional mechanism-targeted larger indications including liver cancer and KRAS‑mutant tumors with leading centers including Dana‑Farber, Memorial Sloan Kettering, and MD Anderson.”

Recent Highlights
Plinabulin Clinical Presentations

March 2025 (Oral Presentation at the Immuno-Oncology 360o Summit in Boston): Plinabulin combination regimen showed clinically meaningful responses in patients of multiple cancer types who failed prior immunotherapies, including NSCLC and Hodgkin lymphoma, with prolonged PFS.

Phase 1 investigator-initiated study of Plinabulin + PD-1/PD-L1 inhibitor + radiation (MD Anderson Cancer Center) showed promising data in re-sensitizing Hodgkin lymphoma for patients who failed 12 to 16 prior lines of treatments including stem cell transplant, CAR-T, and PD-1 inhibitor with duration of response of over 19 months.
