Protox presents Phase 2 BPH data at the World Congress of the Société
Internationale d'Urologie
Based on the very promising results from this open label Phase 2 study, the Company initiated a double-blinded Phase 2 placebo controlled clinical trial called TRIUMPH in the first quarter of 2009. The Company recently announced that enrollment of this study is complete and anticipate top-line results in the fourth quarter of 2009.
About PRX302
PRX302 is the lead drug in the company's PORxin(TM) technology platform. PORxin drugs are pore-forming pro-drugs that are activated by specific proteases produced at elevated levels on the surface of target cells. PRX302 has been generated by engineering the naturally occurring toxin proaerolysin so that it is activated by prostate-specific antigen (PSA), an enzyme that is overproduced in patients suffering from prostate cancer and BPH. Once activated, the drug punches holes in the cells causing the contents to leak out and ultimately cell death.
About BPH
BPH is a common urological condition characterized by painful and bothersome symptoms that include difficulty in initiating a urine stream, a sense of urgency, dribbling, incomplete emptying of the bladder, waking several times during the night to urinate and sometimes the presence of blood in the urine. More than half of all men will have symptoms of BPH by the age of 60 and as many as 90% may suffer from BPH after the age of 80. Current oral therapies mainly provide symptomatic relief, may take months before they take effect and can trigger a range of side effects including sexual dysfunction and hypotension. It is estimated that in the seven largest global markets approximately 10 million men are treated annually with oral therapies and these products encompass approximately U.S.
