E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of the core of the study is to demonstrate that a single TRUS-guided intraprostatic injection of NX-1207 provides a long lasting therapeutic improvement of LUTS associated with benign prostatic hyperplasia (LUTS/BPH) in patients not adequately controlled by medical therapy with α-blockers, as assessed by a change from baseline in the International Prostate Symptom Score (IPSS) total score. |
|
E.2.2 | Secondary objectives of the trial |
Secondary objectives are to evaluate: - the effects on storage and voiding LUTS - the effects on Quality of Life (QoL) - the effects on maximum urinary flow rate (Qmax), post void residual volume and prostate volume - the safety profile of the procedure and of the study drug - the patient’s global assessment of treatment - the persistence of the treatment effects at 18 and 24 months after the NX-1207 injection

Immunosuppressive disorders, such as Human Immunodeficiency (HIV) Virus, Acquired Immune Deficiency Syndrome (AIDS), lymphoproliferative disorders; 15. Acute or chronic intestinal disease, such as ulcerative colitis, Crohn’s disease, acute gastroenteritis in the run-in period; acute painful perianal disorder; 16. Unstable cardiovascular or cerebrovascular disease (including acute myocardial infarction, unstable angina pectoris, by-pass, Percutaneous Transluminal Coronary Angioplasty (PTCA), congestive heart failure NYHA Class III-IV, stroke, transient ischemic attack and episodes of cardiac arrhythmia requiring treatment in the last 6 months); 17. Any condition that would interfere with the subject’s ability to provide informed consent, to comply with study instructions, or that might confound the interpretation of the study results, such as dementia, psychosis, manic depressive disorder, post traumatic stress disorder, stroke, Alzheimer’s, depression, psychiatric illness, history or current evidence of drug or alcohol abuse within the last 12 months etc.; 18. Participation in a study of any investigational drug or device within the previous 6 months; 19. Hypersensitivity or contraindication to tamsulosin use (see Appendix 15.6); 20. Use of prohibited medications that could endanger subjects performing the intraprostatic injection or that could interfere with the evaluation of study parameters (please refer to Section 6.7); 21.
