The main objective of this study is to realise serum protein profiles for each patient undergoing a prostate biopsy and to identify relevant proteins.

In men, prostate carcinoma is the first cancer and the second cause of death by cancer. It is a slowly evolving disease with no prognostic marker of poor outcome.

Currently, the Prostate Specific Antigen (PSA) is the only available biological marker. It is a tissue marker and not a tumoral pathology control.

This is why new tissue markers are urgently needed to select patients with unfavourable evolution, in order to treat them rapidly by more effective methods such as chemotherapy, hormonotherapy or radiotherapy. This could improve survival time and quality of life.

Proteomic and clinical data comparison could point to new relevant molecules and permit the development of new biological tests for routine use.

SELDI-TOF-MS (Surface Enhanced Laser Desorption/Ionisation Mass Spectrometry) permits an extremely sensitive analysis of proteins. This method has been substantially ratified by the literature and a number of markers have already been identified, particularly for several cancer pathologies.

As far as prostate carcinomas are concerned, previous proteomic researches on serum have led to diagnostic parameters, differentiating healthy patients, patients with benign lesion and patients having malignant lesions. However, at present, no relevant protein has been identified. Moreover, no study has been carried out to characterize fast-developing lesions, in order to anticipate response to treatments.

The main objective of this study is to realise serum protein profiles for each patient undergoing a prostate biopsy and to identify relevant proteins.

The main judgement criteria will be intensity peaks in the protein profile (area and height) with reference to combined criteria (PSA rate, clinical stage, Gleason score).

Two groups will be compared:

* Group 1: Control (negative biopsy).
* Group 2: Prostate carcinoma (positive biopsy).

This group will be subdivided:

* Group 2a : favourable prognostic according to AMICO classification
* Group 2b : intermediate or unfavourable prognostic according to AMICO classification

This will contribute to setting up an aftercare database combining clinical data with biological data and protein profile.

Patients received the Rezum transurethral needle ablation procedure to treat benign prostatic hyperplasia.

The Rezūm System treats patients with bothersome urinary symptoms associated with benign prostatic hyperplasia (BPH). The Rezūm System utilizes radiofrequency current to generate "wet" thermal energy in the form of water vapor, which is then injected into the transition zone and/or median lobe of the prostate tissue in controlled 9-second doses. The vapor that is injected into the prostate tissue rapidly disperses through the interstitial space between the tissue cells. As the vapor cools, it condenses immediately on contact with tissue and the stored thermal energy is released, denaturing the cell membranes and causing cell death. The denatured cells are absorbed by the body, which reduces the volume of prostate tissue adjacent to the urethra. The vapor condensation process also causes a rapid collapse of vasculature in the treatment zone, resulting in a bloodless procedure.

Evaluate the safety and efficacy of the Rezum System for the treatment of BPH

Prospective, non-randomized clinical trial of subjects with benign prostatic hyperplasia. The objective of the study are to 1) determine the safety and efficacy of the BPH Rezum System and assess its effect on urinary symptoms secondary to benign prostatic hyperplasia (BPH), and 2) further document the safety and post-operative effects of the Rezum System in the treatment of obstructive BPH.

Rezum I Pilot Study for Benign Prostatic Hyperplasia

NxThera Benign Prostatic Hyperplasia Rezum System Pilot Study

International Prostate Symptom Score (IPSS) scores were recorded at Baseline to 1 week, 1 month, 3 months, 6 months, 1 year, then annually to 5 years. The mean change (improvement) in IPSS was calculated. IPSS scores range from 0 (no symptoms) to 35 (severe symptoms). Improvement in symptoms is shown by a reduction in score.

Safety assessed by the frequency of systemic and local serious device related complications and the occurrence of unanticipated device-related adverse effects during treatment and at follow-up, up to 30 days. Due to the nature of the device, any device-related AEs are expected to present themselves during the immediate peri-procedure period (30 days post procedure).

The device related complications that will be compared for this safety endpoint are:

1. Severe Urinary Retention (Retention ≥ 24 hours)
2. Fistula between rectum and urethra
3. Perforation of the rectum or GI tract
4. New incidences of retrograde ejaculation

The proportion of study subjects who were responders were evaluated. A responder is defined as a subject with ≥ 30% improvement in BPH symptoms from baseline as measured by the IPSS.

The proportion of study subjects who were responders were evaluated. For this measure a responder is defined as a subject with ≥ 50% improvement in BPH symptoms from baseline as measured by the IPSS.

Analysis will be provided for proportion of subjects with improvement ≥ 8 points from baseline at 1 week, 1 month, and 3 months, 6 months, 1 year, annually to 5 years

Peak urinary flow rate (Qmax) is the maximum urinary flow rate. It is calculated as milliliters (ml) of urine passed per second. Average results are based on age and sex. Typical uroflow rates ranges from 10 ml to 21 ml per second. An increase in mL/sec corresponds to improved urinary function.

Peak urinary flow rate (Qmax) is the maximum urinary flow rate. It is calculated as milliliters (ml) of urine passed per second. This measure reports the number of subjects who experienced a ≥ 30% improvement from baseline at each follow-up interval.

Peak urinary flow rate (Qmax) is the maximum urinary flow rate. It is calculated as milliliters (ml) of urine passed per second. This measure reports the number of subjects who experienced a ≥3 mL/sec improvement from baseline at each follow-up interval.

Change in post void residual (PVR) urine volume in ml. Post void residual volume was measured by either ultrasound to measure the volume left in the bladder after urination, or by inserting a urinary catheter into the bladder after urination to drain and measure residual urine. Either measurement tool was allowed but the same measurement was to be used pre and post treatment.

Change from baseline in sexual function was measured by the International Index of Erectile Function (IIEF) (Scoring on the IIEF ranges from 1 to 30. An increase in score indicates improvement from baseline)

Rate of Retrograde Ejaculation (when no fluid exits the penis during orgasm (e.g., dry orgasm)

International Prostate Symptom Score (IPSS) scores were recorded at Baseline to 1 week, 1 month, 3 months, 6 months, 1 year, then annually to 5 years. The mean change in IPSS was calculated. IPSS scores range from 0 (no symptoms) to 35 (severe symptoms). Mean change in IPSS scores reported at each follow-up interval. Improvement in symptoms is shown by a reduction in score.

IPSS scores range from 0 (no symptoms) to 35 (severe symptoms). Mean change in IPSS scores reported at each follow-up interval. Improvement in symptoms is shown by a reduction in score.

Results report change in IPSS by follow up interval for subjects treated in both lateral lobes and median lobe vs. subjects treated in lateral lobes alone.

International Prostate Symptom Score (IPSS) scores were recorded at Baseline to 1 week, 1 month, 3 months, 6 months, 1 year, then annually to 5 years. The mean change in IPSS was calculated. IPSS scores range from 0 (no symptoms) to 35 (severe symptoms). Mean change in IPSS scores reported at each follow-up interval and grouped by Baseline IPSS. Improvement in symptoms is shown by a reduction in score.

Pain scores were obtained for all subjects using the Iowa Pain Thermometer. Maximum intraprocedural pain scores were analyzed, together with the pain scores reported at follow-up intervals through 3 months. The treatment pain scores were reported by subjects post-procedure and was based on their recollections. Scale is 0-12 with higher scores corresponding to higher pain reported.

Change in Quality of Life was measured using a QoL question in the IPSS. QoL data were collected at each follow up visit.

One question in the IPSS asked subjects to rate their "quality of life due to urinary symptoms" on a scale of 0 = Delighted to 6 = Terrible.

A reduction in score from baseline equates to improved outcome.

Change in Quality of Life will be measured with the Benign Prostatic Hyperplasia Impact Index (BPHII). Data were collected at specified follow up visits.

BPHII scores range from 0 (no/mild symptoms) to 35 (severe symptoms). A reduction in score from baseline equates to an improvement in symptoms.

Quality of Life was measured using EQ-5D-3L questionnaire. QoL data were collected at each follow up visit. The EQ-5D-3L is a standardized instrument for use as a measure of health outcome and was administered to all subjects to assess the effect of the treatment on the subjects' quality of life. EQ-5D-3L index ranges from -0.109 to 1.000, with 1.000 corresponding to the best health state and -0.109 corresponding to the worst health. Mean change in overall score from baseline is reported.

Quality of Life was measured using EQ-5D-3L questionnaire and collected at each follow up visit. The EQ-5D-3L is a standardized instrument for use as a measure of health outcome and was administered to all subjects to assess the effect of the treatment on the subjects' quality of life. The EQ-5D-3L includes a visual analog scale (VAS) which is a vertical scale with numbers ranging from 0 to 100. Subjects were asked to draw a line to the place on the scale that best represented how good or bad his health was on that day. The worst state a subject can imagine is marked zero, and the best state the subject can imagine is marked 100. Mean change in VAS score from baseline is reported. An increase in score is considered a better outcome.

Quality of Life was measured using EQ-5D-3L questionnaire. QoL data were collected at each follow up visit. The EQ-5D-3L is a standardized instrument for use as a measure of health outcome and was administered to all subjects to assess the effect of the treatment on the subjects' quality of life. Each dimension had 3 possible responses (1 =no problem, 2 =some problem 3 =severe problems) in the relevant health dimension.

Presented below are the scoring counts for each of the dimensions for baseline and follow up interval.

Subject satisfaction assessed using a study specific questionnaire to evaluate the subject's overall satisfaction of the procedure at 1 week, 1 month, 3 months, 6 months, 1 year, and annually to 5 years.

These will be measured as:

• Proportion of subjects that are satisfied with the procedure overall

Note: Subject Satisfaction Questionnaire is specific to the NxThera Rezūm treatment and 3 of the 7 questions were used to evaluate the subjects' overall satisfaction with the procedure. Within the questionnaire, subjects sometimes did not answer all of the questions, which resulted in a different "n" by question within the same follow-up time point.
