NEWARK, Del.<\/span> and NANJING<\/span>, China<\/span><\/span>, Feb. 3, 2026<\/span><\/span> \/PRNewswire\/ — Biosion, Inc. (“Biosion”), a global, clinical-stage biotechnology company developing innovative antibody-based therapeutics, today announced that the first patient has been dosed in a Phase 1a\/1b<\/span> Investigator-Initiated Trial (IIT) evaluating BSI-082, a highly differentiated, fully human anti-SIRP\u03b1 monoclonal antibody. The study is sponsored by and being conducted at the Mays Cancer Center, <\/b>a National Cancer Institute (NCI)-designated Cancer Center and part of The University of Texas at San Antonio’s<\/span> Health Science Center.<\/p>\n This clinical milestone highlights the medical community’s strong interest in Biosion’s oncology assets and follows the company’s recent transformative partnership with Aclaris Therapeutics for its immunology portfolio.<\/p>\n Collaborating to Unlock Innate Immunity<\/b><\/p>\n BSI-082 is engineered to block the CD47-SIRP\u03b1 “don’t eat me” signal, a critical checkpoint tumor cells use to evade macrophage phagocytosis. Unlike other candidates in the class, BSI-082 was designed using Biosion’s proprietary H\u00b3 Antibody Discovery Platform<\/b> to overcome historical development challenges.<\/p>\n Key differentiators of BSI-082 include:<\/b><\/p>\n “The initiation of this trial by a premier institution like the Mays Cancer Center serves as powerful validation of BSI-082’s scientific rationale and therapeutic potential,” said Mingjiu Chen, Ph.D., Founder and CEO of Biosion<\/b>. “BSI-082’s unique profile\u2014specifically its ability to potently block the ‘don’t eat me’ signal without compromising patient safety\u2014positions it as an ideal combination partner for standard-of-care therapies, particularly antibody-drug conjugates (ADCs). We are honored to support Dr. Sarantopoulos and his team in this study, which represents a key step in our strategy to maximize the value of our oncology assets through high-quality clinical partnerships.”<\/p>\n Study Design and Strategic Combinations<\/b><\/p>\n The Phase 1a\/1b<\/span> study is an open-label, dose-escalation and dose-expansion trial designed to evaluate the safety, tolerability, pharmacokinetics, and preliminary antitumor activity of BSI-082 in patients with locally advanced or metastatic solid tumors.<\/p>\n “Targeting the innate immune system via the SIRP\u03b1-CD47 axis offers a compelling therapeutic strategy for refractory tumors,” said John Sarantopoulos<\/span>, M.D.<\/b>, associate professor of medicine in the Division of Hematology and Oncology, medical oncologist, and principal investigator at the Mays Cancer Center. “We are excited to lead the clinical evaluation of BSI-082, whose design addresses key limitations of earlier generation agents. We look forward to exploring its potential to improve outcomes for patients, particularly in combination with ADCs.”<\/p>\n About Biosion<\/b>\u00a0<\/p>\n Biosion is a global, clinical-stage biotechnology company dedicated to developing innovative antibody therapies to improve outcomes for patients with immunological and oncological diseases.
