In August 2025, SynOx completed enrollment in the Phase 3 TANGENT clinical trial; topline data are expected in the first quarter of 2026.

Tom is one of the most accomplished corporate development leaders in our industry, with nearly four decades experience guiding transformational partnerships, licensing deals, and global strategic growth initiatives at Johnson & Johnson.”
“Together, their complementary expertise significantly strengthens SynOx’s readiness for commercialisation, partnering, and other strategic pathways as we continue to advance emactuzumab’s late-stage clinical program and prepare for the milestones ahead. I would also like to take this opportunity to sincerely thank Jon Edwards, who has stepped off the Board, for his invaluable contributions and guidance during an important period of SynOx’s growth.”

SynOx Progress and Near-Term Milestones
In August 2025, SynOx completed enrollment in TANGENT, its global, randomized, double-blind, placebo-controlled registrational Phase 3 trial of emactuzumab in TGCT patients who are not amenable to or would not benefit from surgery. Top-line data are expected in the first quarter of 2026.
Emactuzumab previously received Fast Track Designation from the U.S. Food and Drug Administration for TGCT, reflecting the seriousness of the disease and the unmet medical need.
Based on clinical work to date, SynOx believes that emactuzumab represents a next-generation therapeutic option with the potential to address key patient needs by offering an effective, short-course treatment with rapid onset and a durable response — enabling individuals with TGCT to better manage their disease and move forward with their lives.
About TGCT and Emactuzumab
TGCT is a rare, locally aggressive tumour of the synovium, tendon sheaths, and bursa membranes that can cause substantial pain, stiffness, reduced mobility, and diminished quality of life; more than 50% of diffuse TGCT cases recur within three years after surgery.
Emactuzumab is a humanised monoclonal antibody targeting CSF-1R, designed to inhibit and deplete macrophages in tumour tissue; in clinical studies it has shown rapid tumour reduction, functional improvement, and a manageable safety profile in TGCT.
Additional details on TANGENT are available at ClinicalTrials.gov (NCT05417789).
