  • New Clinical Data from MD Anderson Presented at the Society for Immunotherapy of Cancer's 38th Annual Meeting

  • 80% DCR (disease control rate) in non-radiated tumor with Durable Responses in Heavily Pretreated Patients in 6 different cancers

  • Full data was presented at SITC's 38th Annual Meeting; The Company will host a call at 8:30 a.m. ET today. Dial in: 877-407-0792, conference title: Clinical Significance of Plinabulin SITC Presentation with PI Dr. Steven Lin from MD Anderson

NEW YORK, Nov. 07, 2023 (GLOBE NEWSWIRE) -- BeyondSpring Inc. (NASDAQ:BYSI) ("BeyondSpring" or the "Company"), a global clinical-stage biopharmaceutical company focused on using a groundbreaking technology platform for drug discovery and developing innovative therapies to improve clinical outcomes for patients with high unmet medical needs, today announced new data that translates preclinical proof-of-concept to clinical evidence of plinabulin's immunomodulating activity. BeyondSpring and MD Anderson presented the data at the Society for Immunotherapy of Cancer's (SITC) 38th Annual Meeting on Nov 4th in San Diego, CA on an open-label, Phase 1 basket study at The University of Texas MD Anderson Cancer Center in cancer patients after progressing on PD-1, PD-L1 and/or CTLA-4 antibodies (NCT04902040) in six cancer types.

Based on preclinical models, where plinabulin plus radiation and anti-PD-1 antibody enhances dendritic cell (DC) activation, T-cell proliferation, and abscopal effect, a clinical study was initiated to test these findings. At the Phase 1 data cut-off (August 31, 2023), 19 heavily pretreated patients with 6 different cancers were exposed to plinabulin (30 mg/m2) after radiation initiation to an amendable lesion (3-6 hours apart) plus anti-PD-1 antibody, including pembrolizumab or nivolumab. 11 out of 14 patients eligible for efficacy assessment per RECIST criteria and had measurable target lesion responses in the non-irradiated tumor lesion. Disease control rate evaluates the ...
