Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

OPTIMUM is a study designed to compare the ability of ultra-high resolution transrectal micro-ultrasound (microUS) and multiparametric MRI (mpMRI)/US fusion to guide prostate biopsy.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The purpose of the Clinical Investigation Plan and Study Protocol is to present information for the OPTIMUM clinical investigation, including the scientific basis for the study, the procedural details, the ExactVu High Resolution Micro-Ultrasound System, its safety details, and administrative details. It has been designed in such a way as to optimize the scientific validity and reproducibility of the results of the study in accordance with current clinical knowledge and practice so as to fulfill the objectives of the investigation.

Primary Study Purpose

DIAGNOSTIC

Blinding Strategy

NONE

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Microultrasonography only

Subjects will undergo biopsy using micro-ultrasound only.

Group Type ACTIVE_COMPARATOR

Microultrasonography Targeted Biopsy

Intervention Type DIAGNOSTIC_TEST

All subjects will be biopsied no matter their arm randomization. In this group, MicroUS targets will be identified and sampled.

Microultrasonography + MRI

Subjects will undergo fusion biopsy using mpMRI and micro-ultrasound

Group Type ACTIVE_COMPARATOR

Microultrasonography Targeted Biopsy

Intervention Type DIAGNOSTIC_TEST

All subjects will be biopsied no matter their arm randomization. In this group, MicroUS targets will be identified and sampled.

MRI Targeted Biopsy

Intervention Type DIAGNOSTIC_TEST

All subjects will be biopsied no matter their arm randomization. In this group, mpMRI targets will be identified and sampled.

MRI + Conventional Ultrasonography

Subjects will undergo biopsy using mpMRI fused with regular ultrasound

Group Type ACTIVE_COMPARATOR

MRI Targeted Biopsy

Intervention Type DIAGNOSTIC_TEST

All subjects will be biopsied no matter their arm randomization. In this group, mpMRI targets will be identified and sampled.
