BioXell Reports Preliminary Phase IIa Results in Non-Bacterial Chronic Prostatitis


Effect on pain comparable to placebo, effect observed on inflammation and lower urinary tract symptoms

Milan, Italy, September 27, 2006 – BioXell S.p.A. (SWX: BXLN) today reported preliminary results from its proof of concept trial of Elocalcitol in patients with Non-bacterial Chronic Prostatitis. The effect of Elocalcitol was found to be no different from that of placebo on the primary endpoint, focused mainly on pelvic pain. In contrast, positive data for several secondary endpoints provide further support for the potential efficacy of the compound in both Benign Prostatic Hyperplasia (BPH) and Overactive Bladder (OAB), indications for which Elocalcitol is also currently in clinical development.
The primary endpoint analysis of the 3 month trial in 129 patients showed that both Elocalcitol and placebo reduced the total NIH/Chronic Pelvic Pain Syndrome (CPPS) symptom score by 15 points out of a possible score of 43. One of the secondary endpoints of the trial was the level of IL-8 in the semen, a marker for inflammation in which Elocalcitol showed a clinically relevant reduction. A positive signal was also detected in lower urinary tract symptoms (LUTS) - frequency, urgency, and nocturia - as recorded in micturition diaries. In particular, among patients who began the trial with a frequency of urination greater than 10 times per day, 55% of patients on Elocalcitol saw their frequency decrease to less than 10 (versus only 14% on placebo). The trial again confirmed the excellent safety profile of the compound which was no different from placebo.
Francesco Sinigaglia, CEO of BioXell, commented: “CP remains a disabling condition for which no approved treatment exists. While we are disappointed that Elocalcitol has no effect on chronic pelvic pain and will therefore not be developed further in indications where pain is a central component, we are very pleased to see clinical evidence that the compound reduces IL-8 levels, a marker for inflammation, as these correlate with BPH progression. This finding also opens up additional development opportunities for the compound, and the new data on LUTS are also very encouraging for both OAB and BPH, since they confirm the effect of Elocalcitol on the bladder.”
BioXell is currently conducting a 500+ patient Phase IIb trial in BPH which is on track to complete enrolment by the end of this year. Early next year, the Company will begin a large, pan-European Phase IIb trial in OAB which could potentially be used as one of the pivotal trials for registration.
The data analysis is still ongoing and will be finalized (including sub-group analysis) in the following weeks.
