pSivida Announces Positive Phase IIa Trial Results in Liver Cancer
Results of the second group of 4 patients, 12 weeks after their BrachySil(TM) treatment, revealed an average tumor regression by volume of 80% as determined by CT scanning. In some smaller tumors 100% regression was observed, a level of performance not seen with other intratumoral approaches. The study also demonstrated that there were no product-related adverse effects. Patients will continue to be monitored for 6 months post treatment.
BrachySil(TM) is a micron-sized particle in which the isotope 32-phosphorus is immobilized. pSivida believes that this product is unique in that it demonstrates a very high degree of isotope retention, thus reducing the risk of soluble radioactive material affecting healthy hepatic tissue or entering the circulation and causing systemic toxicity.
