Clinical Trial Summary

RT-310, a novel implant, is intended to minimally invasive treat locally the prostate gland for the management of prostate disease, while minimizing side-effects. The objectives of the study are to assess whether RT-310 is safe and feasible for the participant population.

Description:

The RT-310 study is a first in human Phase 1 multi-center prospective, non-randomized dose escalation study to evaluate the safety and feasibility of RT-310 for treatment of Benign Prostatic Hyperplasia (BPH). Study participants will have placement of RT-310 and be followed through 180 days.

• Gender: Male
• Age group: 50 Years to 80 Years

Eligibility

Key Inclusion Criteria:

• Male gender

• Diagnosis of symptomatic BPH

• Age = 50 years up to 80 years

• International Prostate Symptom Score (IPSS) = 13

• Prostate volume 30 to 80 cc per ultrasound

• Inadequate response and/or refusal of medical therapy for LUTS

Key Exclusion Criteria:

• Current urinary retention or at significant risk of urinary retention after drug washout

• Have an obstructive or protruding median lobe of the prostate

• Previous BPH surgical procedure or implants, urethral stricture, Any prior minimally invasive intervention (e.g. TUNA, Balloon, Microwave, Rezum, UroLift) or surgical intervention of the prostate

• Previous pelvic surgery or irradiation

• History of neurogenic or atonic bladder

• Stress urinary incontinence, mixed or urge incontinence

• History of prostate or bladder cancer, confirmed or suspected malignancy of prostate or bladder

• History of compromised renal function or upper urinary tract disease

• Other co-morbidities that could impact the study results such as: severe cardiac arrhythmias uncontrolled by medications or pacemaker; congestive heart failure New York Heart Association (NYHA) III or IV; History of uncontrolled diabetes mellitus; significant respiratory disease in which hospitalization may be required

• Known immunosuppression (i.e. AIDS, post-transplant, undergoing chemotherapy)

• No more than two documented active urinary tract infections (UTI) by culture or bacterial prostatitis within last year documented by culture (UTI is defined as >100,000 colonies per ml urine from midstream clean catch or catheterization specimen)

• Current gross hematuria and/or visible hematuria with participant urine sample without known contributing factor

• Presence of a penile implant or stent(s) in the urethra or prostate

• PSA > 10 ng/ml unless prostate cancer is ruled out by biopsy. If PSA is > 4 ng/ml and = 10 ng/ml, prostate cancer must be ruled out to the satisfaction of the investigator via additional tests including digital rectal exam (DRE) and/or biopsy

• Sensitivity to RT-310

• Unable to undergo magnetic resonance imaging (MRI) such as presence of cardiac pacemaker or implanted cardiac defibrillator

• Parkinson's disease or other neurologic disease that may impact bladder function such as stroke, TIA, multiple sclerosis
