Nymox Pharmaceutical Corporation (NASDAQ:NYMX) announced today that the Company's U.S. long-term extension prospective double-blind Phase 3 BPH studies NX02-0017 and NX02-0018 of fexapotide triflutate (NX-1207) for BPH have successfully met the pre-specified primary endpoint of long-term symptomatic statistically significant benefit superior to placebo. Fexapotide showed an excellent safety profile with no evidence of drug-related short-term or long-term toxicity nor any significant related molecular side effects in the 2 studies (n=978).
The Company now intends to meet with authorities and to proceed to file where possible in due course for regulatory approvals for fexapotide triflutate in various jurisdictions and territories.
The Company will present a public webinar and conference call today July 27 at 4:30 p.m. EDT (see below).
The primary endpoint variable of the long-term study was improvement in the AUA BPH Symptom Score which was statistically significant (p<.02) in fexapotide-treated patients compared to placebo, at a median duration of 42 months (3.5 years) after a single double-blind injection treatment of fexapotide vs. saline placebo. In addition, responder analysis for the primary endpoint variable met the prespecified endpoint (p<.01). All subjects from both studies with 2 years or more duration follow-up after a single painless injection were eligible, however all documented treatment failures of any duration in the studies from day 1 onward were also included in the data as treatment failures. Patients were followed double-blind up to 65 months (5.4 years) after a single injection. Highlights of the pivotal Phase 3 extension top-line results are summarized as follows:

Patients were followed double-blind up to 65 months (5.4 years) after a single injection. Highlights of the pivotal Phase 3 extension top-line results are summarized as follows:
- Median duration of 3.5 years from a single injection treatment mean improvement of 5.3 points in AUABPH Symptom Score. Statistically significant (mean p<.025; median p<.02) vs saline placebo injection.
- Mean improvement of 7.1 points in AUA BPH Symptom Score (primary endpoint variable) after median duration of 3.5 years in first-line BPH treatment of fexapotide treated subjects (p<.025 vs placebo).
- Patient responder rate: Statistically significant higher proportion (64%) of long-term improved patients in AUA BPH Symptom Score (primary outcome variable) after a single injection in fexapotide treated subjects vs controls (p<.005).
- Improvement of nocturia: Percentage of patients with stabilization or improvement of frequency of nocturia in fexapotide treatment superior to placebo (p<.03).
- Reduced incidence of surgery: Subjects in Phase 3 studies NX02-0020 and NX02-0022 with 1 or 2 injections of fexapotide had statistically significant reduction of BPH surgery within 24 months off exapotide treatment (1.7% incidence of surgery in 2 years) (p<.02 vs placebo).
- Safety profile highly superior to existing treatments. Minimal or no sexual, hormonal or cardiovascular or other debilitating side effects.
- Reduced cancer risk in Phase 2 data: U.S. Phase 2 data showing therapeutic effect of fexapotide on prostate cancer. Phase 2 data showed fexapotide treated low grade localized prostate cancer (Gleason3+3 or less) had statistically significant less progression compared to controls. By comparison, some commonly used older approved BPH treatments have been linked to increased cancer risk.
- Enhanced compliance and patient convenience compared to oral medications. Fexapotide is given as a single painless office treatment injectable. Older approved oral medications generally involve daily pills intended for the rest of the patient's life.
