Nymox Announces New Positive Results at 54 Months in Long TermStudy of NX-1207 for Benign Prostatic Hyperplasia

HASBROUCK HEIGHTS, N.J.--(BUSINESS WIRE)--Apr 30, 2008 - Nymox Pharmaceutical Corporation (NASDAQ: NYMX) today announced new 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 two Phase 1-2 studies initiated 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 54 months after NX-1207 treatment. These subjects were last assessed at 42 months after treatment.

Overall, 75% of the patients in the new outcome study treated with NX-1207 reported no current drug treatment for their BPH and had a mean improvement of 11.1 points in AUA Symptom Score. In addition, 38% 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 9.8 points. This sustained improvement in BPH symptom score after NX-1207 treatment compares favorably to the 3.5 to 5 points reported in published studies of currently approved BPH drugs, which, unlike NX-1207 treatment, require uninterrupted, daily administration to be effective.

Paul Averback, CEO of Nymox, said, "This new data on NX-1207 showing sustained symptomatic improvement after 54 months provides further evidence of enduring benefits from NX-1207 treatment for BPH. NX-1207 thus far has had none of the well known sexual and other bothersome side effects of other BPH treatments."

In the NX-1207 studies, subjects received a one-time single dose of NX-1207 administered by intraprostatic injection by a urologist in an office setting. The entire procedure lasted on average 5-10 minutes, with the injection taking 1-2 minutes, and did not require anesthesia or catheterization. There have been no significant side effects from NX-1207 in the trials to date.

Overall, subjects in the most recent study's Intent-to-Treat group who received 2.5 mg of NX-1207 reported a mean improvement in total AUA BPH Symptom Score of 9.71 points after 90 days as compared to the mean improvement of 4.13 points for subjects randomized to finasteride, an approved drug treatment for BPH. This difference was statistically significant (p=0.001). The AUA BPH Symptom Score measures self-assessed severity of BPH symptoms in 7 areas: 1) sensation of incomplete emptying of the bladder; 2) need to urinate frequently; 3) stopping and starting during urination; 4) urgent need to urinate; 5) weakness of urinary stream; 6) need to push or strain during urination; and 7) urination during sleep (nocturia). Published studies of currently approved drugs for BPH show AUA BPH Symptom Score improvement typically in the 3.5 to 5 point range.

The results of the blinded clinical trials to date have shown that men treated with NX-1207 reported statistically significant improvement in BPH symptoms 3 months after a single NX-1207 treatment. In two multi-center Phase 2 U.S. prospective randomized blinded clinical trials, the aggregated mean improvement in the Primary Endpoint of BPH Symptom Score for 2.5 mg NX-1207 was 10.3 points or a 44% improvement in Symptom Score. To date, subjects treated with NX-1207 have reported no serious side effects from the treatment, including no (0%) significant sexual side effects.

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, and can cause acute urinary retention requiring immediate medical attention.
