Summary of Clinical Use Click here for help
The EMA has granted fresolimumab orphan designation for the treatment of focal segmental glomerulosclerosis (FSG).
Fresolimumab has reached Phase 2 clinical trial for glioma in addition to FSG. A phase 1 trial for diffuse systemic sclerosis has been completed.
Unfortunately, inhibition of TGF-β1 (which exerts a potent cytostatic effect on premalignant cells) has been noted to induce squamous cell carcinoma development in Phase 1 clinical trial [3].
Mechanism Of Action and Pharmacodynamic Effects Click here for help
TGF-β is a key regulator of glomerular visceral epithelial cells which play a pivotal role in the pathogenesis of FSG [2]. Fresolimumab binds to all isoforms of TGF-β, effectively blocking TGF-β activity, thereby reducing the pathological tissue damage and scarring observed in FSG.
In oncology, TGF-β is over-expressed in certain malignancies, playing an important role in facilitating growth, progression, and migration of tumour cells. By binding to and neutralising all isoforms of TGF-β, fresolimumab is expected to inhibit tumour cell growth, angiogenesis, and migration.
