Nymox Pharmaceutical announces new positive results from long term outcome study of NX-1207 for BPH

May 5 2010

Nymox Pharmaceutical Corporation (Nasdaq:NYMX) today announced new 2010 positive results from a long term outcome study of NX-1207 for benign prostatic hyperplasia (BPH). The study evaluated symptomatic progress of U.S. patients involved in the Company's NX02-0012 and NX02-0013 Phase 1-2 studies of NX-1207 initially undertaken in 2003. Patients treated with NX-1207 were followed-up on an unselected and as available basis and assessed for symptomatic improvement, treatment outcomes, and durability of efficacy 6 ½ years after a single treatment with NX-1207.

As an inclusion criterion, all subjects enrolled in these studies were previous failures on conventional approved drug treatments. Data was available for 69% of the patients from the initial studies. Overall, 55% of the men in the new outcome study treated with NX-1207 reported no subsequent surgical treatment and no current drug treatment for their BPH and had a mean improvement of 14.3 points in AUA Symptom Score. In addition, 36% of the patients reported no other approved treatments at any time for their BPH since their original treatment with NX-1207, with a mean improvement of 14.5 points.

This sustained improvement in BPH symptom score after NX-1207 treatment compares favorably to the 3 to 5 points reported in published studies of currently approved BPH drugs, which, unlike NX-1207 treatment, require permanent daily administration to be effective.  Currently approved drugs also have undesirable side effects such as loss of libido, impotence, retrograde ejaculation, dizziness, and other problems.

The Company has successfully reported four U.S. clinical trials of NX-1207 and conducted a series of long term follow-up studies of available subjects from those trials in order to monitor and assess long term safety and efficacy of NX-1207 treatment for BPH. The follow-up trials to date have provided further confirmation of the excellent safety and side effect profile of NX-1207 and evidence of enduring benefit for a significant percentage of patients treated with NX-1207.

NX-1207 has entered its Phase 3 development program, the last stage before filing with the FDA for approval. NX-1207 is injected by a urologist in an office setting and involves little or no pain or discomfort.

BPH treatment represents a growing market with more than 100 million men worldwide being estimated to suffer from BPH symptoms. The disorder is a common affliction of older men, affecting approximately half of men over age 50 and close to 90% of men by age 80, and is associated with growth in prostate size as men age. BPH causes difficulties with urination associated with aging, such as urination at night, urge to void frequently, hesitancy, weak stream, and other problems.
