• Orphan Drug Designation Request Submitted

  An Orphan Drug Designation request has been submitted to the FDA for Vdelta2+ Gamma Delta T Cells targeting glioblastoma multiforme. The agency acknowledged receipt on March 30, 2026, and is currently reviewing the application.

• Preclinical Data Presentation at WCP 2026

  JY BioMed, which licenses the GDT technology, will present preclinical data at the World Congress of Basic and Clinical Pharmacology (July 12–17, 2026) showing that intracranial γδ T cell therapy eliminates glioblastoma in models.

• Regulatory Milestone for Lead Asset

  This represents the first regulatory submission for the company's GDT platform since its recent SPAC merger. Orphan designation would bring incentives such as tax credits, waived fees, and 7-year market exclusivity upon approval.

• Addressing High Unmet Need in GBM

  With a median survival of ~15 months under current standard of care, glioblastoma remains an area of significant unmet medical need. The GDT platform's MHC-independent mechanism may help overcome immune evasion in solid tumors.

SL Science has taken a concrete regulatory step by requesting Orphan Drug Designation from the FDA for its lead GDT cell therapy, which targets glioblastoma—a lethal brain cancer with a median survival of roughly 15 months. The FDA has acknowledged receipt and is now reviewing the application. If granted, the designation would unlock incentives such as potential accelerated review and market exclusivity, thereby reducing program risk. In parallel, the company announced that preclinical data will be presented at a major pharmacology congress next week, offering a chance to further validate the platform. For a micro-cap biotech that recently completed a SPAC merger and disclosed going-concern uncertainties, this marks the first tangible regulatory catalyst for its pipeline.
