Brief summary:
Approximately one million transrectal prostate biopsies are performed annually in the U.S., and the risk of post- biopsy infection is increasing due to greater antibiotic resistance of rectal flora. Preliminary data demonstrates that a transperineal MRI-targeted biopsy approach under local anesthesia compared to the standard practice transrectal MRI-targeted prostate biopsy has a much lower risk of infection, comparable pain/discomfort and may improve detection of prostate cancer.

This randomized controlled trial will be the first prospective study to evaluate in-office transperineal MRI targeted prostate biopsy.

The investigators hypothesize that a transperineal MRI-targeted biopsy approach under local anesthesia compared to the standard practice transrectal MRI-targeted prostate biopsy has a much lower risk of infection, comparable pain/discomfort and may improve detection of prostate cancer.

Detailed description:
Prostate cancer is the most commonly diagnosed malignancy in U.S. men. There are approximately 1 million prostate biopsy performed annually in the U.S. Almost all biopsies are performed as an office based procedure in under 15 minutes. The precision of biopsy has improved over the last decade with the introduction of MRI guidance/targeting of suspicious lesions within the prostate.

However, significant limitations remain with this approach, including a significantly increasing risk of post-biopsy infection. This arises because more than 97% of all prostate biopsy are performed via a transrectal approach that introduces rectal bacteria with each pass of the biopsy needle into the sterile urinary tract. The current risk of post-transrectal biopsy infection, even with antimicrobial prophylaxis, is high at approximately 7% overall with 3% (30,000 men) requiring hospitalization annually.

Transperineal biopsy is an alternate approach that eliminates the direct introduction of bacteria from the rectum to the prostate. This approach, which is performed without antimicrobial prophylaxis, instead passes the biopsy needle through the perineal skin and pelvic floor.

Transperineal biopsy has not been widely adopted for several reasons. Historically, it has been considered too painful for patients in the clinic and thus was traditionally performed under general anesthesia. The added time, inconvenience and cost has limited its national adoptance. Second, when transrectal biopsy was initially adopted over 40 years ago, antibiotic resistance of rectal flora was not a challenge.

Beyond the potential for in-office transperineal biopsy to significantly reduce or eliminate biopsy infections, transperineal biopsy may also improve cancer detection: studies of transperineal biopsy (performed under general anesthesia) demonstrate higher detection rates for prostate cancer, particularly for anterior zone tumors, compared to transrectal biopsy. This is notable, as anterior tumors are difficult to sample with transrectal. Anterior tumors are also twice as likely to occur in African American men. In fact, our research demonstrates that some of the outcomes disparities in African American men may stem from an underdiagnosis of anterior prostate cancers.

Although transrectal biopsy is used widely, it is associated with a significant and increasing risk of biopsy infections due to growing antibiotic resistance, highlighting the urgent need for a safer alternative approach to prostate biopsy. The study investigators have refined a transperineal approach under local anesthesia with MRI-targeting/guidance without the need for antibiotic prophylaxis. The investigators hypothesize that transperineal MRI targeted biopsy will: (1) largely eliminate post-biopsy infections and costly hospitalizations for urosepsis; (2) be performed in the office with similar discomfort and non-infectious complications compared to transrectal MRI targeted biopsy; and (3) have significantly better detection of prostate cancer.

This multi-center randomized controlled trial will be conducted to evaluate in-office transperineal MRI targeted vs. transrectal MRI targeted biopsy, the current gold standard. This has transformative impact to change current standard of practice.

Arms:
arm 1: Patients will receive a transrectal MRI-guided prostate biopsy. arm 2: Patients will receive a transperineal MRI-guided prostate biopsy.

Interventions: intervention 1: Transperineal MRI-guided prostate biopsy intervention 2: Transrectal MRI-guided prostate biopsy intervention 3: Antibiotic (prophylaxis)
Intervention descriptions: intervention 1: Transperineal prostate biopsy will be performed under local anesthesia in the office. This approach avoids transrectal needle tracking. intervention 2: Transrectal prostate biopsy is currently the most popular approach to evaluate a positive screening test for prostate cancer. intervention 3: For men undergoing transrectal biopsy, antibiotic prophylaxis will be administered in accordance with guidelines from the American Urological Association (AUA).

No antibiotic prophylaxis will be administered for men undergoing transperineal biopsy.

Protocol Summary 
Full Title: 
Randomized controlled trial assessing transperineal prostate 
biopsy to reduce infection complications 
Clinical Phase: 
II 
Principal Investigator: 
Jim C. Hu, M.D., M.P.H. 
Sample Size: 
N= 1,702 
Study Population: 
Men who are aged at least 18 years with: history of Grade Group 
1 or 2 prostate cancer, first diagnosed prior to date of planned 
biopsy (active surveillance cohort); clinical concern for the 
presence of prostate cancer as determined by the treating 
urologist and prior negative prostate biopsy performed ≤36 
months prior to date of planned biopsy (prior negative cohort); 
Men without previous prostate biopsy (first time prostate biopsy) 
Accrual Period: 
Approximately 31 months  
Study Design: 
Prospective, randomized trial with 1:1 ratio to either the 
transperineal or transrectal biopsy group. Participants will be 
assessed for adverse events, pain and discomfort immediately and 
7 days post-biopsy.  
Intervention Description: 
Transrectal prostate biopsy (TR-Bx) under local anesthesia is 
currently the most commonly used approach to evaluate for the 
presence of prostate cancer. A limitation of TR-Bx is the need for 
biopsy needles to pass through the rectal mucosa on their 
trajectory to the prostate, placing men at high risk of an infectious 
complication. An alternative method for performing prostate biopsy 
is via a percutaneous transperineal approach. One limitation of 
transperineal prostate biopsy (TP-Bx) has been the historic need 
for it to be performed under general or spinal anesthesia in order 
for patients to tolerate the multiple required needle passes through 
the perineal skin. Due to recent technical advances TP-Bx may 
now be safely performed under local anesthesia.  
Primary Objective: 
To compare infection adverse events of TP-Bx vs. TR-Bx 
performed under local anesthesia. 
Secondary Objectives: 
To compare other adverse events such as bleeding and urinary 
retention. To compare detection rates of clinically significant and 
insignificant prostate cancer.

Study Objectives 
Primary Objective: The primary objective of this study is to compare the incidence and severity 
of infectious complications between the transperineal and transrectal approaches to prostate 
biopsy. 
Secondary Objectives: Secondary objectives of this study include comparing the incidence of 
other adverse events, associated pain, and cancer detection rates between the transperineal 
and transrectal approaches. 
2. 
Background 
Approximately one million transrectal prostate biopsies (TR-Bx) are performed annually in the 
United States.1 The number of prostate Bx is expected to increase due to the demographic 
growth of the aging male population. Moreover, 44% of U.S. men undergoing initial biopsy 
report having a repeat biopsy within five years.2 Additionally, more than half of men diagnosed 
with prostate cancer currently opt for active surveillance, which requires serial repeat biopsy to 
monitor for disease progression.3 Therefore, biopsy use will only increase with greater adoption 
of active surveillance and the greater number of aging men. The safety and effectiveness of this 
common procedure will impact 1 out of 3 U.S. men at least once during their lifetimes when they 
undergo biopsy.  
Due to the need for biopsy needles to pass through the rectal mucosa on their trajectory to the 
prostate, TR-Bx is associated with a significant risk of infectious complications. The needle 
travels through the “dirty” rectal mucosa to the “clean” prostate at least 12 times,4 and fecal flora 
may seed the vascular prostate gland and bloodstream, leading to infection.5,6 One systematic 
review suggests this rate may be as high as 5%.7  The United States Preventive Services Task 
Force (USPSTF) Grade C recommendation for PSA screening considered adverse events 
associated with biopsy among the harms of PSA-based screening.8 Despite antibiotic 
prophylaxis, 44% of men experience bacteriuria and 16% experience bacteremia after TR-Bx.9  
Furthermore, the risk of post-biopsy infection has increased in recent years due to the growing 
incidence of antibiotic resistance.10 Nam first reported an alarming four-fold, population-based 
increase in post-Bx infection hospital admissions from 0.6% in 1996 to 3.6% in 2005 among  
75,190 patients.11 In particular, men with fluoroquinolone-resistant bacteria in the rectum are at 
increased risk for post-Bx infection and sepsis,12 which can result in dire complications such as 
limb gangrene/amputation, endocarditis, meningitis, disseminated intravascular coagulation 
(DIC) or death.13–18  
As an alternative to the transrectal approach, prostate biopsy may be performed percutaneously 
through the perineal skin. Due to avoidance of the rectum, transperineal prostate biopsy (TP-Bx) 
is associated with an overall lower risk of infectious complications. At some centers, this has 
obviated the need for perioperative antibiotics, which is reinforced by the Society of  
Interventional Radiology Guidelines. 19,20 One additional benefit of TP-Bx is that this procedure 
offers better sampling of the anterior prostate, which is missed with the transrectal approach in 
men with larger prostate volumes due to benign prostatic hyperplasia.21 The biopsy core 
excursion is 2 cm, and therefore sampling of the anterior prostate from the rectum is limited. In 
contrast, the TP approach has relative ease of access to the anterior prostate.6 This is reflected 


in greater detection of clinically significant prostate cancer in retrospective studies with 
transperineal22–25 under general anesthesia (49%-91%) vs. transrectal24,26–31 Bx approaches (14-
42%). Given more than 80% of first-time biopsy nationally are performed without 
MRItargeting,32,33 the utility of in-office transperineal vs. transrectal MRI-targeted biopsy must be 
evaluated as this applies to a large population of men. For instance, the American Urological 
Association professional guidelines were updated to recommend MRI use for first-time biopsy in 
early 2020;34 however, lack of insurance coverage and limited access for urologists to the costly 
MRI-targeted biopsy platform contribute to a large population of men who need to be evaluated 
in the repeat biosy setting of active surveillance and prior negative biopsy.  
Despite the aforementioned benefits of TP-Bx, this procedure has seen limited adoption due to 
the historic need for it to be performed under general anesthesia in order for patients to tolerate 
the required multiple needle sticks to the perineal skin. Additionally, because of the need for 
biopsy needles to traverse the pelvic floor muscles and vascular prostate apex, TP-Bx is 
believed to have a higher risk for urinary retention and bleeding as compared to the traditional 
transrectal approach.  
In recent years, the development of novel local anesthetic techniques and needle guides has 
permitted TP-Bx to be performed in the office setting with a more favorable side-effect 
profile.20,35,36 There has, however, been slow adoption of this procedure by only a handful of 
centers. In fact, national estimates of TP-Bx use place this figure closer to approximately 1-2%.  
In this study, we aim to compare the safety, tolerability, and cancer detection rates of TP-Bx 
versus TR-Bx within the contexts of a randomized clinical trial. The results of this study will 
provide high level medical evidence regarding which method of prostate biopsy carries the best 
risk to benefit ratio for men undergoing evaluation for prostate cancer.

4. 
Study Procedures 
4.1 Study Enrollment and Randomization 
Eligible patients will be informed of the study by the study urologist and research staff.  
Interested participants may also learn more about the study through online resources such as 
ClinicalTrials.gov or through study informational brochures. All potential subjects will be allowed 
as much time as needed to consider study participation. Patients choosing to participate in the 
study will be consented within the privacy of a clinical exam room. Study staff will explain to 
each potential subject the research objectives, risks and benefits of study participation, and the 
subjects’ rights and responsibilities. For patients who are scheduled for biopsy, electronic 
consent will also be available via phone. Eligible patients will be contacted by a member of the 
study team (i.e. investigator or research coordinator), who will explain the study to the patient. 
The patient will also receive a link to the electronic consent form via email or MyChart message. 
This study will utilize either a traditional one-stage or a two-stage consent process. The reason 
for having the one-stage consent is there are a few sites in which the predominant approach is 
transperineal. Therefore, this two-stage consent does not work. With the one-stage consent,  
patients give permission to participate in the study prior to randomization (tradtional RCT 
consent). With a second-stage consent, subjects who meet all eligibility criteria will sign the 
firststage consent form. Patients will have the option to sign the consent in person or 
electronically. First-stage consent will register the subject to the study and will allow 
investigators to use their data from their medical record and post-biopsy questionnaire 
responses for research purposes. Subjects who sign first-stage consent will be randomized in a 
1:1 ratio to receive TP-Bx or TRBx. The patients’ first-stage consent or their traditional one-
stage consent will be valid for eight months to accommodate for biopsy scheduling. This will 
reduce the number of re-consents and align with the standard of care timeline for biopsy 
procedures. Biopsies are often scheduled as far out eight months from their clinic visit. 
Participants will be consented remotely using an electronic version of the informed consent form 
that follows federal, state, and local regulations, as applicable. We will implement the following 
procedures for electronic informed consent. 
The informed consent document(s) will be sent to the subject or their Legal Authorized 
Representative (LAR), if applicable, via secure email sent by REDCap prior to the scheduled 
consent discussion. The subject or LAR will be asked to review the consent document prior and 
during the consent discussion with a study staff member via phone or approved 
teleconferencing service (i.e., Zoom). The study staff member will confirm the subject or LAR 
has read and has the capacity to appreciate all aspects of the information presented in the 
consent process for the research study. The subject or LAR will be encouraged to ask 
questions. If agreeing to participate, the subject or LAR will sign the consent form using 
electronic informed consent (eConsent) via REDCap. A computer, tablet or touch screen phone 
will be used to capture digital signatures. The person conducting consent will also sign the 
electronic informed consent (eConsent) document in a contemporaneous manner. Subjects will 


be provided with a digital copy of the completed form via email. The informed consent 
discussion and process will be documented by the study team in the subject’s medical record or 
study record. 
If a subject does not have access to a touch screen phone, computer or tablet, cannot work with 
remote electronic informed consent, or the remote electronic informed consent cannot be 
obtained for any other reasons, the consent may be conducted and documented at an in-person 
visit prior to study activities via paper consent form or through REDCap on an ITS tagged 
device. 
The assignment sequence will use randomly permuted blocks of unequal size stratified by 
urologist, PSA (<4, 4-9.9, ≥10 ng / mL) and biopsy indication (prior negative vs. active 
surveillance) and implemented by the randomization model in REDCap, which prevents an 
investigator from learning allocation before a patient is unambiguously registered on study and 
from changing allocation afterwards, thus ensuring full allocation concealment. For men with 
prior biopsy, we exclude men with a PSA >20 ng/mL.  
For the REDCap randomization model, randomization of subjects will occur on the data 
collection form where the randomization field is located. Before a subject is randomized, a 
'Randomize' button will appear next to that field. When a user (who has been given appropriate 
'Randomize' user privileges) clicks that button, a pop-up box will appear that will allow the user 
to randomize the subject. After a subject has been randomized, the grouping (i.e. transrectal or 
transperineal biopsy) will become permanently locked and unmodifiable. The randomization field 
will always be locked and unmodifiable both before and after randomization has occurred for a 
subject.  
Randomization is unblinded, and research coordinators of respective enrolling sites will inform 
their patients of the assigned cohort. 
Subjects randomized to TR-Bx will receive transrectal biopsy. Subjects randomized to TP-Bx will 
undergo a second consent discussion with the enrolling investigator, where the risks and 
benefits of transperineal biopsy will be explained. Subjects can then decide whether to undergo 
standard transrectal biopsy or transperineal biopsy. Subjects who agree to undergo TP-Bx will 
sign the second-stage consent form.  
4.2 Data Collection & Confidentiality 
Study data will be prospectively collected from patient medical records and patient surveys. In 
all participating centers, the site-specific research coordinator will perform baseline data 
acquisition and medical record abstraction. This data will be entered into standardized clinical 
report forms housed within a REDCap environment and hosted by WCM. Each patient will be 
assigned a unique study identifier. 
REDCap (Research Electronic Data Capture) is a secure, web-based application designed 
exclusively to support data capture for research studies. The REDCap platform will be 
partitioned to permit read/write access only to site-specific records such that individual sites will 
be able to access records for their own subjects, exclusively. REDCap has a secure email and 
web-based data collection interface that may be utilized for collecting data. The site-specific 
research coordinator will determine individual patients’ preferred method of survey response 


and may collect survey data either through mail, telephone, REDCap, or during an in-person 
visit. 
Only the WCM research coordinator will be able to review de-identified data across sites to 
conduct data quality checks and share data quality with the study biostatistician.  
To ensure accuracy of data entered in the REDCap database from source documents (including 
surveys and medical record abstract), sites will perform 100% visual review and conduct double 
data entry for a sample (i.e., 10%) of the data. 
Data quality checks will be conducted every 6 months, coinciding with Data Safety and 
Monitoring reviews.  
For protocol deviations fitting immediately reportable criteria, the DSMC’s primary concern lies 
with whether the deviation has the potential to negatively impact subject safety or integrity of 
study data or whether the deviation places subjects at greater risk of harm (including physical, 
psychological, economic or social harm). If the DSMC makes determinations that the reported 
protocol deviation impacts either, it may recommend modifications, suspension or termination of 
the study.    
Interim study findings will be communicated in cases where modifications are recommended. 
The DSMC will require the PI to submit confirmation to the DSMC that the modification(s) have 
been made, or to submit a reason why the PI did not agree with the DSMC’s recommendation.

4.4 Antibiotic Administration 
For patients undergoing a TR-Bx, antibiotic prophylaxis will be administered in accordance with 
guidelines from the American Urological Association (AUA).37 No antibiotic prophylaxis will be 
administered for patients undergoing a TP-Bx. 
4.5 Biopsy Procedure 
A meeting of study investigators will take place before recruitment to review and ensure 
standardization of biopsies approaches. Investigators will follow the technique described by Kubo 
et al. to administer lidocaine during TP-Bx.20 For both transperineal and transrectal approaches, 
20 mL of 1% lidocaine will be used, respectively, to standardize local anesthesia. At each site, 
however, the choice of commercial MRI-targeted biopsy platform will be left to the physicians’ 
discretion.  
In both transperineal and transrectal biopsy arms for MRI-targeted biopsy, the number of 
systematic biopsy cores will be standardized to 12 cores. The technique for TR-Bx is performed 
as described by Kasivisvanathan et al.22 A total of 12 systematic biopsy cores will be obtained 
from the peripheral zone of the prostate at the base, mid gland, and apex. Locations of the 12 
systematic cores are: Right lateral base, Right lateral midgland, Right lateral apex, Right medial 
base, Right medial midgland, Right medial apex, Left lateral base, Left lateral midgland, Left 
lateral apex, Left medial base, Left medial midgland, and Left medial apex. The technique for 
TPBx is performed as described by Urkmez et al.38. Locations of the systematic cores will be 
obtained as follows: 2 cores each at Right posterior lateral, Right posterior medial, Left posterior 
lateral, and Left posterior medial, as well as 1 core each at Right anterior lateral, Right anterior 
medial, Left anterior lateral, and Left anterior medial. 
In both transperineal and transrectal biopsy arms, the number of targeted biopsy cores will be 
standardized to 3 cores per target, with a maximum of three ROIs permitted to be chosen for 
targeted biopsy. MRI-targeted biopsy registration (i.e., matching of the image of the target on MRI 
with the real-time image of the prostate during biopsy) may be performed by means of visual 
registration or software-assisted registration. 
De-identified video capture of each site’s first 10 TP-Bx and TR-Bx will be distributed for review 
among investigators to monitor for variation in biopsy technique. Deviations from the technique 
that may occur during routine clinical care will be recorded for each case, monitored by the WCM 
DSMC and compared between groups. Research coordinators at each site will randomly select 3 
TP-Bx and 3 TR-Bx for video upload every 3 months. Investigators will review and discuss during 
quarterly video-conferences to ensure consistent procedural fidelity throughout the study. 
4.6 Duration of Follow Up 
Patients will be followed for approximately 7 days following biopsy to evaluate for adverse 
events. Subjects experiencing an adverse event beyond 7 days stabilization will be followed 
until resolution or stabilization. 


5. 
Measurement of Outcomes 
5.1 Adverse events 
The primary objective of this study is to compare the incidence and severity of infectious 
complications experienced by patients undergoing TP-Bx versus TR-Bx. Patients will be 
assessed for complications by way of electronic questionnaire administered 7±2 days post 
biopsy using a REDCap site hosted at Weill Cornell Medical Center. For patients unable to 
complete the questionnaire electronically, responses will be obtained via telephone interview. 
Any patient indicating that they experienced an adverse event will be contacted by the study 
team to seek further details. Additionally, all relevant medical records will be requested. Adverse 
events will be classified in accordance with Common Terminology Criteria for Adverse Events 
(CTCAE) v5.0.  
The primary outcomes are infection rates of TP-Bx versus TR-Bx.  
The secondary outcomes are patient-reported pain and anxiety, and comparison of 
noninfectious complications such as bleeding and urinary retention rates, and cancer detection.

5.2 Pain, Anxiety and Discomfort  
A questionnaire will be given to patients immediately after the biopsy and at 7±2 days post-biopsy 
(Appendix). The questionnaire captures discomfort and pain and fear-anxiety using a numerical 
rating scale (0-10), with higher scores indicating greater intensity of symptoms. The questionnaire 
also asks about the presence or absence of adverse events, with reporting of significant adverse 
events (fever, chills, urinary retention, urinary tract infection, treatment from a doctor) subject to 
follow-up from study staff. 
Infectious complications will be captured as: (1) uncomplicated urinary tract infection (UTI): 
dysuria, urgency, frequency or hematuria without fever and with or without pyuria (>5 white 
blood cells per high-powered field or positive leukocyte esterase on urine dipstick) or bacteriuria 
(≥ 105 colony-forming units/mL); (2) complicated UTI: fever, flank pain, nausea or vomiting with 
or without pyuria and bacteriuria; (3) urosepsis: criteria for sepsis, severe sepsis, and septic 
shock39  were combined and categorized as urosepsis.40  
5.3 Biopsy Pathology 
The proportion of men diagnosed with clinically significant cancer and clinically insignificant 
cancer will be compared by biopsy approach. Detection of prostate cancer will be captured from 
the final pathology report. We will record the prostate cancer grade, number and location of 
positive biopsies for transrectal (location: left vs. right, medial vs. lateral, apex, mid, and base) 
and for transperineal (location: posterior medial, posterior lateral, and anterior), as well as the 
maximum cancer core length (in mm), and total number of negative cores. In order to compare 
outcomes, prostate cancer grade will be categorized into insignificant (Gleason grade group 1) 
and clinically significant (grade group ≥ 2).22  


6. 
Statistical Considerations 
We define infection complication as any of the following: (1) fever requiring medical advice or 
intervention; (2) chills requiring medical advice or intervention; or (3) UTI diagnosed by healthcare 
professional.41 We aim to enroll 1,702 (n=682 active surveillance, n=620 prior negative biopsy, n 
=400 first time biopsy) subjects in this study, with equal randomization between groups. We 
assume that the infection rate in the transperineal group is 0.5%. Given a one-sided α of 0.10, the 
power to reject the null hypothesis of no difference in infection rates will be >80% if the event rate 
in the transrectal group is 2.0%. The event estimate is consistent with published post-transrectal 
biopsy infection rates range from 1% to 17.5%41–49 and the 2017 AUA prostate biopsy guidelines 
cite an infection risk of 5-7%.37 
Analysis of infection, detection of clinically significant cancer (i.e. Grade Group 2+), over-detection 
of clinically insignificant cancer (i.e. Grade Group 1), presence vs. absence of other biopsy related 
complication grade 2 or above and, separately, Grade 1 (patient-reported hematuria, 
hematospermia or hematochezia) will be by logistic regression with site and prior negative vs. 
active surveillance as fixed effect covariates. The Barnard's test will be used to analyze the data. 
Absolute risk differences will be calculated by applying the odds ratio from the regression to the 
prevalence in the transrectal group, with 95% CI obtained by bootstrapping. As a sensitivity 
analysis for high-grade cancers missed on biopsy, we will include as an event any detection of 
grade group ≥2 cancer up to two years after randomization, whether detected by subsequent 
biopsy or upgrading on surgical pathology, as a binary variable. We will also explore whether the 
relative effects of transperineal biopsy on cancer detection varies by race or diagnostic setting 
(active surveillance vs. prior negative) by adding race (African ancestry yes or no) or setting  
(active surveillance vs. prior negative) and the associated interaction terms in two separate 
logistic regression models. 
Rates of missing data are expected to be extremely low because all outcomes are assessed within 
a short period of time after biopsy. Hence, we do not anticipate having to use statistical methods 
to handle missing data. However, if rates of missing data are more than 5%, we will implement 
multiple imputation using chained equations. 
To compare the detection of clinically significant cancer biopsy with systematic vs. MRI-targeted 
biopsy, stratified by transperineal vs. transrectal, the analyses will be conducted separately for the 
prior negative biopsy and active surveillance cohorts separately. For the prior negative biopsy 
patients, we will create a model with the outcome of clinically significant cancer and predictors of 
the linear predictor from the standard Prostate Biopsy Collaborative Group model plus PI-RADS 
version 2 MRI score and MRI prostate volume.50 For the active surveillance cohort, we will use a 
similar approach but use the Canary “base” model for biopsy outcome in active surveillance 
patients.51 We will report the increase in discrimination associated with using MRI volume and 
PIRADS score and conduct decision curve analysis, a decision-analytic technique that weighs the 
value of avoiding unnecessary biopsy compared to missing high-grade cancer, to assess the  
clinical utility of the models.52

KEY INFORMATION ABOUT THIS RESEARCH STUDY
You are being asked to be a subject in a research study because you have an indication to 
undergo a prostate biopsy as recommended by your physician. 
The following table is a concise and focused presentation of key information to assist 
you in understanding why you might or might not want to participate in the research.
Purpose
This is a research study to evaluate the comparative effectiveness 
and tolerability of outpatient transrectal prostate biopsy versus 
transperineal prostate biopsy, both MRI-targeted.
Consent Process
Typically when participating in a research study, all the information 
is provided upfront in one consent form. Instead, this is a two-step 
consent process that gives only information needed at the time.
This is the first stage of the consent process, where you are 
consenting to participate in a research study that allows us to track 
and compare prostate biopsy outcomes.
Experimental/ 
Investigational
You will not receive any experimental drugs or procedures as part of 
this study.
You will be randomly assigned to receive one of two comparable 
outpatient prostate biopsy procedures that are currently available.
If you are selected to receive the transrectal biopsy, there will be no 
further consent discussions related to this research and you will 
receive medical treatment as usual. You will also fill out research 
questionnaires, as described below.
If you are selected to receive the transperineal biopsy, we will talk to 
you about it then. You will decide at that point in time if you want to

have the transperineal biopsy. You do not have to have it if you do 
not want to. If you are selected for the new approach and decide to 
have it, you will sign another consent form at that time.
This second consent will discuss the risks and benefits and other 
information specific to the transperineal approach. You will never 
receive any treatment without us telling you about it first. You will 
always have the chance to say “Yes” or “No” to any treatment.
After the biopsy, you will fill out a questionnaire that asks about urinary 
and sexual function, and complications following the procedure. Your 
health information will be de-identified and stored by the hospital.
Voluntary Participation
Your decision to be in this study is voluntary.
Withdrawal
If you decide to be in this study and then change your mind, you can 
leave the study at any time without penalty. 
Length of Participation
Your participation in the study is expected to last up to 7 days. 
During that time, you will have 2 study visits: a screening visit and 
day of biopsy visit. You will also complete a questionnaire 
immediately after your biopsy and 7 days after biopsy.  
Procedures
The main procedures in the study include:

Transrectal prostate biopsy; or

Transperineal biopsy

Questionnaires
The study doctor will explain which procedures are being done for 
research, and which would be done as part of your standard care 
even if you don’t participate.
Risks 
Taking part in this research may expose you to risks (side effects). 
There are risks from study procedures. Side effects may range from 
being mild to life-threatening and may go away with treatment or be 
permanent. 
The common/main risks of the biopsy include:

Blood in urine, stool, and/or semen

Infection

Discomfort

Urinary retention

Bleeding due to accidental injury
The study doctor will explain the risks of this research to you before 
you decide about participation.

DISCLOSURE OF FINANCIAL INTERESTS  
Weill Cornell Medicine, the sponsor of this study, is providing funds on a per subject basis for 
conducting this research study.  
PURPOSE OF THE STUDY
Doctors know a lot about the performing prostate biopsies. However, we are always trying to 
learn more and improve our skills for our patients’ benefit. We would like to try and make 
prostate biopsies safer, with less side effects for the patient and look for a better way to find 
cancer.

In this study, we will monitor if there are problems after a participant’s standard of care prostate 
biopsy. We will also document the results of the biopsy and patient-reported quality of life.
We are asking those individuals who join the study if we can offer them an alternative and 
comparable approach to prostate biopsy. Those who agree to participate may hear about this 
approach and decide whether they are interested. None of the changes we are considering 
have significant risks or involve large changes to the prostate biopsy.
NUMBER OF SUBJECTS AND LENGTH OF STUDY
About 1,702 subjects are expected to participate in this study at 12 research sites in the United 
States.   
Your participation in this study is expected to last 7 days.  
STUDY PROCEDURES
If you take part in this study, you agree to have your routinely collected clinical data used for research 
purposes. Questionnaires will be also administered immediately after your biopsy and during a 7 day 
follow up visit to assess symptoms after your procedure. 
Please advise your study doctor or their team of any medications you are taking.  In addition, if 
you are taking any over-the-counter drugs or herbal supplements which you have obtained from 
the drug store, grocery store, etc., you should advise the study doctor or their team.
As part of this study, you may be will be randomly assigned to receive one of two comparable 
outpatient prostate biopsy procedures that are currently available. Randomization means that you are 
put into a group by chance.  It is like flipping a coin.   Neither you nor the your study doctor will 
choose what group you will be in.  You will have a 1 in 2 chance of being placed in any group.
If you are selected to hear about the transperineal approach, we will talk to you about it then. You will 
decide at that point in time if you want to have it. You do not have to have it if you do not want to. If 
you are selected for the new approach and decide to have it, you will sign another consent form at 
that time.
This second consent will discuss the risks and benefits and other information specific to the 
alternative approach. You will never receive any treatment without us telling you about it first. You will 
always have the chance to say “Yes” or “No” to any treatment.
If you are selected for the transrectal approach, there will be no further discussions related to this 
research and your active participation on this study will end after you complete the post-biopsy 
questionnaires.
Clinically Relevant Results
If results of study procedures (e.g. blood tests, imaging scans) provide clinical information that 
may be important to your health care, you will be told about those results. 
PARTICIPANT RESPONSIBILITIES
As a participant in this study, you will have certain responsibilities, including the following:

Attend all study visits and, if needed, reschedule appointments as soon as possible

Follow the instructions of the study team

Check with the study doctor before taking any new medicines (including prescription, over-
the-counter, vitamins and herbal supplements)


RISKS AND DISCOMFORTS
For research studies involving prostate biopsy, there may be risks. These risks will be discussed 
with you by the study doctor and/or your regular doctor.
Risks and side effects related to the prostate biopsy we are studying include:
Likely

Blood in semen (92.6%)

Blood in urine (65.8%)

Discomfort or pain during or following the procedure (43.6%)

Blood in stool (36.8%)
Possible

Infection – may range from urinary tract infection to sepsis, a potentially life-threatening 
condition caused by the body’s response to an infection (5% for transrectal; 0.1% for 
transperineal)

Urinary retention (1%)

Bleeding due to accidental injury (1%)
There may also be side effects, other than listed above that we cannot predict. Other drugs may 
be given to make side effects that occur less serious and less uncomfortable. Many side effects 
go away shortly after the prostate biopsy, but in some cases side effects can be serious, long 
lasting or permanent.
NEW INFORMATION
You will be notified in a timely manner if important new findings become known that may affect 
your willingness to continue in the study. 
For example, if we learn about new risks, we will share that information with you.  If we think you 
need to know quickly, the study doctor or their staff may call you. If we do not think you need to 
know quickly, we will tell you at your next visit.  If you still want to participate, we may ask you to 
sign a new consent form.    
BENEFITS
There is no guarantee that your condition will improve as a result of your participation in this 
study.  It may stay the same or worsen.  However, the information learned from this study may 
help other people with this disease in the future.
ALTERNATIVES TO STUDY PARTICIPATION
You do not have to participate in this study to receive treatment for your condition. Instead of 
being in this study, you have these options:

You may choose not to participate in this study.

You may choose a standard transrectal MRI-guided biopsy without being in the study.

You may choose a standard transperineal MRI-guided biopsy without being in the 
study.
The study doctor will discuss study alternatives with you and their risks and benefits.
