This study is designed to demonstrate the safety and efficacy of a second transrectal intraprostatic injection of NX-1207 given to subjects with Benign Prostatic Hyperplasia (BPH) who previously received an injection of NX-1207 in an earlier U.S. clinical trial of NX-1207.

Condition Intervention Phase
Benign Prostatic Hyperplasia
Drug: NX-1207
Phase 3

Study Type: Interventional
Study Design: Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Phase 3 Multicenter Prospective Open Label Clinical Safety Evaluation of Re-Injection of NX-1207 for the Treatment of BPH: Two Doses 1-7 Years Apart

Further study details as provided by Nymox Corporation:

Primary Outcome Measures:
  • Safety [ Time Frame: 180 days ] [ Designated as safety issue: Yes ]
    Safety parameters as determined by Adverse Events, clinical laboratory test results, vital signs, physical exam and electrocardiogram (ECG).

Secondary Outcome Measures:
  • Symptomatic Improvement [ Time Frame: 90 days ] [ Designated as safety issue: No ]
    Symptomatic improvement as measured by the change in American Urological Association (AUA) Symptom Index from baseline at 90 days. The AUA Symptom Index is a standardized questionnaire that uses seven questions relating to associated BPH symptoms to provide an assessment of symptom severity on a scale from 0 (no symptoms) to 35 (most severe).

  • Prostate Volume Change [ Time Frame: 90 days ] [ Designated as safety issue: No ]
    Change in prostate volume from baseline to 90 days as measured by transrectal ultrasonography

  • Change in Urinary Peak Flow [ Time Frame: 90 days ] [ Designated as safety issue: No ]
    Change in Urinary Peak Flow (Qmax) from baseline to 90 days as determined by urinary flow-rate recording (uroflowmetry).

  • Symptomatic Improvement [ Time Frame: 180 days ] [ Designated as safety issue: No ]
    Symptomatic improvement as measured by the change in AUA Symptom Index from baseline at 180 days.
