Clinical Trial Summary

The purpose of the this international, multicenter, randomised, single-blind, parallel group, Phase III study is to demonstrate that a single transrectal ultrasound (TRUS)-guided intraprostatic injection of NX-1207 provides a long lasting therapeutic improvement of Lower Urinary Tract Symptoms (LUTS) associated with Benign Prostatic Hyperplasia (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.

Exclusion Criteria:

• Previous surgical or invasive prostate treatments such as TURP, TUMT, TUNA, laser or any other minimally invasive treatment;
• Acute or chronic prostatitis or suspected prostatitis including chronic pain, intermittent pain or abnormal sensation in the penis, testis, anal or pelvic area in the past 12 months;
• PSA = 10 ng/mL. In case of a PSA between 4.0 and 10.0 ng/mL, prostate cancer must have been ruled out to the satisfaction of the clinical Investigator by an historical biopsy;
• Prostate or bladder cancer, history of pelvic irradiation;
• Active or recurrent urinary tract infections (more than 1 episode in the last 12 months);
• History of neurogenic bladder or LUTS secondary to neurologic disease;
• Use of self-catheterization for urinary retention;
• Post-void residual urine volume > 200 mL;
• Haematuria which has not been appropriately evaluated to determine safe subject participation;
• Renal insufficiency (serum creatinine >2.0 mg/dL);
• Liver insufficiency (any liver function tests [LFTs]>2x upper limit of normal [ULN]);
• Poorly controlled diabetes (type 1 or type 2), as determined by HbA1c >6% and/or glycosuria;
• Any bleeding disorder such as haemophilia, clotting factor(s) deficiency or bleeding diathesis;
• Immunosuppressive disorders, such as Human Immunodeficiency (HIV) Virus, Acquired Immune Deficiency Syndrome (AIDS), lymphoproliferative disorders;
• Acute or chronic intestinal disease, such as ulcerative colitis, Crohn's disease, acute gastroenteritis in the run-in period; acute painful perianal disorder;
• 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);
• 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.;
• Participation in a study of any investigational drug or device within the previous 6 months;
• Hypersensitivity or contraindication to tamsulosin use;
• Use of prohibited medications that could endanger subjects performing the intraprostatic injection or that could interfere with the evaluation of study parameters;
• Men planning to have children in the future;
• Any other condition that may interfere with the study or endanger the subject.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Long term follow-up evaluation	The following data will be evaluated: Percentage of subjects requiring medical therapy, MIST, TURP or surgery for LUTS/BPH and time to treatment failure; Change from baseline in the total score of the IPSS; Change from baseline in QoL due to urinary symptoms; Change from baseline in general health-related QoL (EQ-5D-5L); SAEs and episodes of acute urinary retention.	24 months
Primary	Change from baseline in the total IPSS score.	The primary efficacy parameter is the change from baseline in the total score (Questions 1 to 7) of the IPSS at 12 months.; The IPSS questionnaire will be filled by the subjects in blind conditions and will be reviewed by the investigators for its completeness. Validated local translations of the IPSS questionnaire will be used in each country.	12 months
Secondary	Effects on Lower Urinary Tract Symptoms	Change from baseline in IPSS total score at 1, 3, 6 and 9 months; Change from baseline in IPSS subscores for storage symptoms; Change from baseline in IPSS subscores for voiding symptoms; Response rate by IPSS	1,3,6,9 and 12 months
Secondary	Effects on Quality of Life (QoL) due to urinary symptoms	Change from baseline in IPSS subscore Quality of Life due to urinary symptoms; Change from baseline in BPH Impact Index	1,3,6,9 and 12 months
Secondary	Effects on general health related Quality of Life	The change from baseline in the EQ-5D-5L questionnaire at 12 months or in case of early termination will be considered.; The EQ-5D-5L questionnaire is a standardised validated instrument for use as a measure of health outcome.	12 months
Secondary	Patient's global assessment of treatment	A patient-rated global assessment of treatment benefit, satisfaction and willingness to continue will be performed at 12 months (or in case of early termination) by using the BSW questionnaire.; The BSW is a validated questionnaire that consists of three, single-item measures designed to capture the patient's perception of the effect of treatment in terms of the relative benefit, their satisfaction, and their intention or willingness to continue on therapy.	12 months
Secondary	Effects on maximum urinary flow rate (Qmax)	To evaluate the effect on urinary flow, the change from baseline in maximum urinary flow (Qmax) at 3, 6, 9, 12 months will be considered. The same validated device and procedure will be used in all centres and a blinded centralized reading is foreseen.	3,6,9 and 12 months
Secondary	Effects on prostate volume	The change from baseline in TRUS assessed prostate volume at 3 and 12 months (or in case of early termination) will be considered.	3 and 12 months
