Nymox Announces New Positive Results from 3 1/2 Year Study of NX-1207 for Benign Prostatic Hyperplasia

HASBROUCK HEIGHTS, N.J.--(HSMN NewsFeed)--Nymox Pharmaceutical Corporation (NASDAQ: NYMX ) today announced positive results from a new 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 3 1/2 years after NX-1207 treatment.

Overall, patients treated with NX-1207 showed a mean improvement of 8.6 points in the primary outcome endpoint of AUA Symptom Score value 42 months after NX-1207 treatment. 50% of these patients reported no additional treatment for the BPH during this period and had a mean improvement of 10.0 points in AUA Symptom Score. 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 3 1/2 years clearly confirms the enduring benefits of NX-1207 treatment for BPH."

The Company previously completed three U.S. trials for NX-1207, including most recently a Phase 2 double-blind, placebo controlled, randomized multi-site U.S. study, which showed positive efficacy and safety results for NX-1207 after 3 months in patients with BPH. Overall, patients treated with NX-1207 showed after 3 months a mean improvement of 9.35 points in AUA Symptom Score values, the standard scale used to evaluate BPH drugs and treatments. This improvement compares favorably to the 3.5 to 5 point reported in published studies of currently approved drugs for BPH and reached statistical significance when compared to placebo. Subjects treated with NX-1207 also showed an overall statistically significant reduction in mean prostate volume. The results of the trial demonstrated the excellent safety and side effect profile of NX-1207. Subjects treated with NX-1207 had no serious side effects. In particular, patients given NX-1207 had no (0%) significant sexual side effects.

The company also recently reported positive long-term outcome results from an 8-19 month study of 116 unselected subjects from 26 U.S. clinical sites in a blinded placebo-controlled study, which reached statistical significance (p=.028). In that study, overall without further NX-1207 treatment, patients initially treated with NX-1207 showed a total pooled mean improvement of 7.4 points in the primary outcome endpoint of AUA Symptom Score values.

The AUA Symptom Score is a standardized measurement of BPH symptoms and includes data on 1) sensations 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 Symptom Score improvement in the 3.5 to 5 point range.

BPH afflicts approximately half of men over age 50 and close to 90% of men by age 80. The disorder causes difficulties with urination associated with aging, such as urination at night, urge to void frequently, hesitancy, weak stream, and other problems.
