TACT Trial Summary

This trial is testing a new cancer treatment that uses MRI-guided ultrasound to destroy prostate tissue in 150 patients. The goal is to evaluate the safety and effectiveness of this new therapy.

Who is the study for?
Men aged 45-80 with localized prostate cancer, a Gleason score ≤3+4, PSA ≤15 ng/ml, and a prostate size within specific MRI measurements. They must be eligible for MRI and general anesthesia, have no major organ issues or severe bladder problems, not on certain medications like hormone therapy recently, and without prior prostate cancer treatments.Check my eligibility
What is being tested?
The study is testing the safety and effectiveness of TULSA-PRO system which uses ultrasound guided by MRI to target and destroy prostate tissue in patients with localized prostate cancer. It's a single-arm trial involving about 150 men who will all receive this treatment.See study design
What are the potential side effects?
Potential side effects may include discomfort from the procedure itself, urinary symptoms such as frequency or urgency, possible erectile dysfunction due to nerve damage during ablation, as well as risks associated with any medical procedure like infection or bleeding.

"Affirmative. According to the information posted on clinicaltrials.gov, this research study is actively recruiting participants and has been since September 21st 2016. 150 people are required from 2 different sites and the trial was recently updated on September 12th 2022."

Answered by AI

What results is the clinical trial designed to achieve?

"The primary objective of this clinical trial, assessed over a one-year period, is to ascertain the proportion of patients achieving a Prostate Specific Antigen (PSA) nadir below 25% relative to their pre-treatment baseline. Secondary outcomes include Erection Firmness Endpoint - which evaluates rate of achievement for firmness sufficient for penetration via International Index of Erectile Function (IIEF), IPSS Endpoint - measuring change in International Prostate Symptom Score before and after treatment, as well as Prostate Biopsy Endpoint - assessing negative prostate biopsies at 12 months post-intervention using transrectal"

Answered by AI

Do I satisfy the criteria to join this medical experiment?

"This clinical trial, now recruiting, is designed to accept 150 males aged 45-80 with prostate cancer at a stage ≤ T2b. Moreover, subjects must have either a Gleason score 3+4 (Part I) or 4+3 (Part II)."
