Brief summary:
This is a prospective, single-center, open-label pilot study of 68GA-PSMA-11 given at a single time prior to PET/CT imaging in men with localized high risk prostate cancer or biochemical recurrence. The imaging agent (68 Ga-PSMA 11 will be administered on an outpatient basis. It will be administered prior to the PET/CT imaging. The objective is to evaluate the distribution of 68GA-PSMA-11 in tissues and to determine if this alters the planned clinical management.

Detailed description:
This is a prospective, open label, single-center, single-arm, pilot diagnostic accuracy study to evaluate the tissue distribution of 68Ga-PSMA Positron Emission Tomography (PET)/CT in 80 patients with high risk localized prostate cancer or biochemical recurrence.

Subjects will receive a single IV dose of 3-7 mCi of 68Ga-PSMA (study drug) followed by PET/CT imaging 60-90 minutes after injection. All patients will be closely monitored with vital signs (blood pressure and heart rate), before and 2 hours following radiotracer administration.

Patients will receive a phone call 2 days following PET/CT to assess for adverse events.

To minimize bias, all PET/CT images will be interpreted by a board-certified radiologist. The radiologist evaluating the images will be blinded to the final outcome, such as the histopathology of any biopsies and the outcome of subsequent imaging.

Patients with study-defined high-risk features who are eligible and scheduled for radical prostatectomy will undergo 68Ga-PSMA-11 PET/CT injection. The results of the 68Ga-PSMA-11 PET/CT may alter patient management in one of several ways, including the decision to not pursue surgical extirpation (e.g. in the event of extensive distant metastasis) in favor of systemic therapy. It is also possible that the extent of surgical resection may be altered, such as non-regional pelvic or retroperitoneal lymph node dissection. The alteration in planned surgical treatment from standard of care will be recorded as a secondary-end point.

Arms:
arm 1: Comparison between the results of 68 Ga-PSMA PET/CT to conventional imaging (bone scan, CT) in men with high risk prostate cancer.

Interventions: intervention 1: 68Ga-PSMA
Intervention descriptions: intervention 1: All subjects enrolled in the study will receive a single IV dose of 3-7 mCi of 68 Ga-PSMA (study drug) followed by PET/CT imaging for detection of tumor location.

2  INTRODUCTION 
 
 
2.1 STUDY RATIONALE  
 
Prostate cancer (PCa) remains the most common non-cutaneous cancer diagnosis in 
males, with an estimated 174,650 new cases in 2019[2]. After lung cancer, PCa 
accounts for the second highest mortality in men. Localized PCa, often screen-
detected using prostate specific antigen (PSA) based blood tests, is highly variable 
in clinical course and risk of progression. Treatment is therefore matched on this 
basis, and includes Active Surveillance for Low-Risk PCa, whereas Intermediate-
and High-Risk PCa are treated by radiation therapy (external beam or 
brachytherapy) or surgery (radical prostatectomy). While durable cure can be 
achieved by these modalities,  biochemical relapse occurs in approximately 35% of 
who have undergone treatment for localized disease[3]. 
There is significant interest in identifying individuals at highest risk of 
biochemical relapse, using a variety of approaches, including genomic-based 
biomarkers. Identification of metastatic disease beyond of the prostate is critical, not 
only for potentially targeted local-therapy (e.g. surgical resection of recurrence or 
targeted radiation therapy) but earlier use of aggressive adjuvant radiation or 
systemic therapies. Imaging based identification of low volume disease outside of

8 
the prostate has been limited by the sensitivity of cross-sectional tomography (CT), 
which relies on nodal morphology (size). The sensitivity of CT or MRI based 
imaging for the detection lymph node metastasis is in the range of 30-80%[4]. 
Detection of bone metastasis once present as osteoblastic lesions can be identified 
by bone-scintigraphy, again with limed sensitivity, especially in asymptomatic 
patients with PSA levels below 20[5]. In spite of these limitations, CT and whole 
body bone scans are widely accepted as the primary imaging modality for staging 
patients, particularly with localized PCa.  
 
2.2 BACKGROUND  
Molecular imaging using various targets and positron emission tomography (PET) 
tracers have been used to improve detection of recurrent prostate cancer. 18F- or 
11C labeled choline as well as 11C-acetate have been previously investigated[6,7].  
Their clinical utility has been limited by non-specific uptake in benign tissue, 
including benign prostatic hypertrophy[8].  18F-Fluciclovine has recently been 
approved owing to it improvement over 11C[9]. Targeting of prostate-specific 
membrane antigen (PSMA) by radiotracer has gained the most contemporary clinical 
interest. PSMA (glutamate carboxypeptidase II, N-acetyl-a-linked acidic dipeptidase 
I, or folate hydrolase) is a type II transmembrane glycoprotein belonging to the M28 
peptidase family is preferentially overexpressed in prostate cancer cells relative to 
other cells. Other tissues may also express PSMA, including kidney, small intestine 
or salivary glands. Importantly, PSMA expression is maintained and may increase 
through the full spectrum of prostate cancer, including advanced disease[10].   
Methods have focused on labeling ligands (Glu-NH-CO-NH-Lys-(Ahx)-
[68Ga(HBED-CC)] also known as 68-PSMA-11) to PSMA with 68-Ga, allowing 
internalization and significant differential contrast between normal and cancerous 
tissues which aids in optimal imaging characteristics[11,12]. Initial studies showed 
that labeling of PSMA-ligand with 68-Ga allowed improved identification of PCa 
recurrence and metastasis [13].  
 
Early data has demonstrated the utility of 68Ga-PSMA with respect to improved 
accuracy of detection and in turn significant impact on  treatment decisions[14]. A 
recent meta-analysis of 68Ga-PSMA PET studies showed promising detection of 
metastasis following biochemical recurrence, even at low PSA levels [PSA >0.2

ng/ml (33% detection rate) and PSA 0.2–0.5 ng/ ml (45% detection rate)][15]. 
Importantly, the vast majority of these studies have been reported from 
retrospective data. 
 
In our study we plan to prospectively study the accuracy and utility of 68Ga-
PSMA 11 and its impact of the treatment related decisions. 
 
 
2.3 RISK/BENEFIT ASSESSMENT   
 
2.3.1 KNOWN POTENTIAL RISKS  
 
2.3.2 KNOWN POTENTIAL BENEFITS  
 
 
The investigational study may determine the presence of disease outside of the 
prostate that is resectable at the time of the surgery and that may improve long 
term outcomes. 
 
 
2.3.3 ASSESSMENT OF POTENTIAL RISKS AND BENEFITS  
 
• Study Imaging Drug Risk: Possible side effects such as rash, nausea, 
headache or fatigue. In clinical studies that used 68Ga-PSMA-11 in the 
same amount being used in this study, no serious adverse events were 
reported.  
• PET/CT scan radiation risk:  the maximum amount of radiation from this 
study is equivalent to 2.43 mSv and less than 1 mSv for non-diagnostic CT 
scan performed to process the PET data. The total radiation dose from the 
study procedure is less than 1/10th the annual exposure allowed for 
occupational workers. Although there are no proven harmful effects from 
this amount of radiation, long-term effects, such as cancer, cannot be ruled 
out with certainty. This dose estimate takes into account only the exposure 
to research procedures in this study. 
• Other risk: pain and infection at the site of the needle stick for the study 
drug injection or for blood drawn for the blood tests.

4 STUDY DESIGN  
 
4.1 OVERALL DESIGN 
This is a prospective, open label, single-center, single-arm, pilot diagnostic 
accuracy study to evaluate the tissue distribution of 68Ga-PSMA Positron 
Emission Tomography (PET)/CT in 80 patients with high risk localized prostate 
cancer or biochemical recurrence. 
 
At screening: participants will sign an approved informed consent, medical history 
and vital signs will be completed. Labs will be drawn for PSA. Eligibility criteria 
will be verified and completed.  
 
Day of the injection:

12 
 Subjects will receive a single IV dose of 3-7 mCi of 68Ga-PSMA (study drug) 
followed by PET/CT imaging 60-90 minutes after injection. Scan time will be 
determined based on the capacity of the PET scanner. Scanning will start from the 
mid-thighs (to minimize radiotracer artifact from accumulation in the bladder) to 
the base of the skull. There may be exceptions based on clinical relevance that the 
scan coverage may be extended.  
All patients will be closely monitored with vital signs, to be assessed before and 
after injection of 68Ga-PSMA-11 (Blood Pressure, Heart Rate). Patients will be 
monitored with respect to vital signs and adverse events during, and 2-hours 
following radiotracer administration for adverse events.  
 
Post injection: 
 Patients will receive a phone call 2 days following PET/CT to assess for adverse 
events that may have develop in a delayed fashion. If there are any concerning 
study-related adverse events, this will be escalated to clinical evaluation by the 
study primary investigators.  
 
 
To minimize bias, all PET/CT images will be interpreted by a board certified 
radiologist with experience in reading such modalities. They will be blinded to the 
final outcome, such as the histopathology of any biopsies and the outcome of 
subsequent imaging.  
 
68-Ga-PSMA PET/CT positivity or negativity will be interpreted, stratified by 
different anatomic regions as previously defined [1].

true positivity and false negative based on imaging follow previously published 
methodology[1].  
 
Surgery (prostatectomy) will take place between 7 3 and 14 days after the 68Ga-
PSMA 11 injection. 
 
If patients with BR show metastasis, attending urologist will evaluate for surgery, 
radiation or chemotherapy.  
  
Follow up in clinic will occur at 2 and 6 months after study drug injection. (Visits 
3 and 4) 
 
In patients with biochemical recurrence, will repeat the PSMA scan within 1 year, 
after they completed treatment and when their PSA still increases  when initial 
PSMA was negative, at PI’s discretion if needed.

4.2 SCIENTIFIC RATIONALE FOR STUDY DESIGN 
 
This is an exploratory, single arm, open label pilot study evaluation of  68Ga-
PSMA Positron Emission Tomography with intraprostatic and/or pelvic lymph 
node uptake determination by PET/CT imaging, with histological confirmation of 
disease localized and staging. Methodical evaluation of 68Ga-PSMA intraprostatic 
and or pelvic lymph node will provide important preliminary data upon which 
further clinical studies can be based. 
 
 
4.3 JUSTIFICATION FOR DOSE 
 
68Ga-PSMA-11 will be used as the radiopharmaceutical agent for PET imaging at 
a dose of 3-7 mCi given intravenously. Dosimetry data are available from 
published data and will reference the Weil Cornell IND application to the FDA.  


68GA-PSMA 11

NIH-FDA Clinical Trial Protocol Template – v1.0 7 Apr 2017 
 
15 
In summary, the published literature and safety studies in humans indicates no 
observed adverse events to the radiopharmaceutical[1,7,16].  Measured dosimetry 
showed that the critical organs affected are, in descending order, the spleen, 
stomach wall, pancreas and bladder. The reported effective dose of 68Ga-PSMA-
11 is 0.0129 mSv/MBq, which is the lowest of the 68Ga based tracers, including 
those used in imaging of neuro-endocrine tumours such as  DOTA-TOC, DOTA-
NOC, DOTA-TATE[17–19].  
68Ga-PSMA can only be administered via intravenous infusion.  The proposed 
dose (3-7 mCi) is based upon joint guidelines from the European Association of 
Nuclear Medicine and The Society of Nuclear Medicine and Molecular Imaging, 
who recommend a dose of 0.049-0.06 mCi/kg.  In an average 75kg adult patient, 
this would be approximately 3.7-4.5 mCi [20]. 
The 68-Ga-PSMA agent will be manufactured using previously reported 
procedures using a generator. Agent release criteria, and validation standards for 
each batch produced will be followed.  
 
 
 
4.4 END OF STUDY DEFINITION 
 
A participant is considered to have completed the study if he has completed all 
phases of the study including the last visit or the last scheduled procedure shown in 
the Schedule of Activities (SoA), Section 1.3. 
Patients who do not complete surgery would be considered Early Termination (pre-
surgery). 
The investigator may withdraw a subject from the trial for any of the following 
reasons: 
1. Protocol violation, 
2. Serious or intolerable  adverse event (that in the opinion of the Investigator, 
requires the subject’s discontinuation), 
3.  The Investigator withdraws the subject (at the Investigator’s discretion for 
reasons other than an adverse event), 
4. The Principal Investigator terminates the study, 
5. The subject requests to be discontinued from the study, or 
6. The subject is lost to follow-up.

scheduled visits and is unable to be contacted by the study site staff.  
 
The following actions must be taken if a participant fails to return to the clinic for a 
required study visit: 
• The site will attempt to contact the participant and reschedule the missed 
visit, during the following week and counsel the participant on the 
importance of maintaining the assigned visit schedule and ascertain if the 
participant wishes to and/or should continue in the study. 
• Before a participant is deemed lost to follow-up, the investigator or designee 
will make every effort to regain contact with the participant (where possible, 
3 telephone calls and, if necessary, a certified letter to the participant’s last 
known mailing address or local equivalent methods). These contact attempts 
should be documented in the participant’s medical record or study file.  
• Should the participant continue to be unreachable, he or she will be 
considered to have withdrawn from the study with a primary reason of lost 
to follow-up. 
 
 
8 STUDY ASSESSMENTS AND PROCEDURES 
 
8.1 EFFICACY AND SAFETY ASSESSMENTS  
 
8.1 Informed Consent 
All subjects must sign and personally date an IRB approved informed consent form 
after receiving detailed written and verbal information about the reason, the nature 
and the possible risks associated with the administration of the study agent prior to 
the initiation of any study-related procedures. This must be done according to the 
guidelines provided in the Declaration of Helsinki, ICH E6 Guideline for Good 
Clinical Practice (GCP), and requirements of Title 21 CFR 50.20 through 50.27. 
The subject must be made aware and agree that personal information may be 
scrutinized during an audit by competent authorities and properly authorized 
persons. However, personal information will be treated as strictly confidential and 
will not be publicly available. 
 
8.2 Medical History

24 
A complete medical history, including prostate cancer history, will be obtained at 
the first screening visit. Site staff will record the subject’s medical history in the 
subject’s source records and transcribe the information onto the medical history 
section of the CRF. Historical information concerning allergies (including food, 
drug and/or environmental) will also be obtained. 
 
8.3 Vital Signs 
Vital signs will include measurement of blood pressure and heart rate. Vital signs 
will be obtained and recorded at the Screening visit, pre- and post- each study drug 
injection, and also 2 hours after the first injection. 
 
8.4 Dispensing Study Drug 
The radiopharmaceutical will be injected through the indwelling catheter at a 
185±74 MBq (5±2 mCi) dose. The estimated radioactive dose will be determined 
by measuring the amount of radioactivity in the syringe pre- and post-injection, 
using an appropriately calibrated radioisotope dose calibrator in accordance with 
the nuclear medicine department’s SOPs. The injected activity will be recorded in 
the subject’s source records and transcribed into the CRF. 
The injection will be given by slow intravenous bolus. Following completion of the 
68Ga-PSMA-11 injection, a normal saline flush (approximately 10 mL) will ensure 
that all 168Ga-PSMA-11 remaining in the infusion line is injected. 
Any administration complication of the drug (e.g., overdose, observable 
extravasation, medication error) will be reported to the Chief of Nuclear Medicine 
and the PI within 24 hours of the event and will be recorded in the subject’s source 
records and transcribed onto the CRF. If the Chief of Nuclear Medicine and the PI 
determine an adverse event occurred after injection or because of extravasation this 
will be reported as outlined in Section 7. 
 
8.5 Computed Tomgraphy (CT) and Magnetic Resonance (MR) Imaging 
A diagnostic quality MR scan (abdomen and pelvis) may be obtained (if clinically 
indicated) prior to surgery if not done within  6 months of the screening visit, if 
clinically indicated. If collected as part of screening procedures, the scan should be 
contrast-enhanced, unless contra-indicated for the subject. If necessary, the scan 
maybe obtained between the first injection of study drug and surgery. 
 
8.6 Bone Scan 
If clinically indicated, a bone scan may be obtained prior to surgery if not done 
within   6 months of the screening visit. If necessary, the scan may be obtained 
between the first injection of study drug and surgery.

according to departmental SOPs. 
 
8.7.1.2 Image Acquisition 
PET scan and Quantitation: Following administration of Ga-68 tracer, each subject 
will have a PET/CT scans at 60-90 min on a Siemens mCT PET/CT scanner 
by using 10-12 bed positions and 3 min/bed. The CT parameters used for 
attenuation correction CT (CAREDose-4D) include a fixed 100 mA tube current 
and a peak voltage of 120 kVp with a 5-mm reconstruction interval. The PET scans 
will be reconstructed by using a Siemens time of flight reconstruction method, 
TrueX-TOF UltraHD-PET with a Gaussian filter, scatter correction, and 5/21 
iterations/subsets. 
 
For the study, using the decay-corrected coronal anterior maximum- intensity 
projections of PET scans, regions of interest (ROI) will be drawn manually around 
the major organs (liver, kidney, spleen, lungs, heart) and any other tissues (tumor, 
muscle) showing visually appreciable Ga-68 uptake. Time-activity curves will be 
constructed by using values of whole-organ activity at the time of imaging. 
Recently, several 18F labeled peptides have been evaluated for imaging studies 
and methods for quantifying biodistribution and tumor localization have been 
described. 
We plan to follow similar methods in our protocol. The percent injected dose in 
each ROI and the clearance kinetics from each organ will be used to estimate the 
radiation dosimetry based on OLINDA/EXM for the adult male phantom.

In order to generate quantitative data of tumor localization for each Ga-68 tracer, 
SUVmean and SUVmax will be generated as previously described. When there is 
no resolution loss or uncertainty in the ROI boundary definition (such as in the 
liver), SUVmean will produce a reliable estimate. However, SUVmax may be a 
more reliable parameter since the maximum value within an ROI is typically 
invariant with respect to small spatial shifts of the ROI. 
 
8.8 Prostatectomy 
Subjects will undergo standard of care surgery as deemed appropriate by the 
patient’s attending urologist. 
 
8.9 Surgical Pathology 
Following radical prostatectomy and/or pelvic lymph node dissection, surgical 
specimens will be brought on ice to the Department of Surgical Pathology for 
tissue processing. Prostatectomy and lymph node specimens will be processed by 
the Department of Pathology in the standard fashion with hematoxylin and eosin 
(H&E) staining for grading and staging. Additionally, immunohistochemistry will 
be performed to confirm, at a microscopic level, that radiolabeled 68Ga-PSMA-11 
co-localizes with tumor foci seen on H&E sections. Tumor foci identified on H&E 
sections will serve as the gold standard for imaging comparison. 
 
 
8.2 ADVERSE EVENTS AND SERIOUS ADVERSE EVENTS 
 
8.2.1 DEFINITION OF ADVERSE EVENTS (AE) 
An adverse event (AE) is any untoward medical occurrence in a patient or clinical 
investigation subject administered a pharmaceutical product, at any dose, which 
does not necessarily have a causal relationship with the treatment. 
An adverse event (AE) can therefore be any unfavorable and unintended sign 
(including an abnormal laboratory finding, for example), symptoms or disease 
temporally associated with the use of a medicinal product, whether or not 
considered related to the medicinal product. 
 
8.2.2 DEFINITION OF SERIOUS ADVERSE EVENTS (SAE)  
 
A serious adverse event (SAE) is any untoward medical occurrence that at any 
dose falls into one or more of the following categories: 
• results in death 


68GA-PSMA 11 
Version:5 
Protocol : Pro00025982 
07/08/2021 
NIH-FDA Clinical Trial Protocol Template – v1.0 7 Apr 2017 
 
28 
• is life-threatening 
• i.e., an event which, in the view of the Investigator, places the subject at 
immediate risk of death from the event as it occurred and does not include an 
event which hypothetically might have caused death if it were more severe 
• requires inpatient hospitalization or prolongation of existing hospitalization. 
 For the seriousness criterion of inpatient hospitalization to apply, an overnight 
stay in the hospital is required. Admission to an ER and release without an 
overnight stay would not satisfy the inpatient hospitalization seriousness 
criterion. 
• results in persistent or significant disability/incapacity 
• where disability is defined as a substantial disruption of a person ability to 
conduct normal life functions, either reported or defined as per clinical 
judgment 
• is a congenital anomaly/birth defect (if exposure to product just before 
conception or during pregnancy resulted in an adverse outcome to the child) 
• is any other important medical event 
• may not result in death, be life-threatening, or require hospitalization, but based 
upon appropriate medical judgment the event may jeopardize the subject or may 
require medical or surgical intervention to prevent one of the outcomes listed in the 
serious definitions above. An important medical event may include development of 
drug dependency or drug abuse. 
 
8.2.3 CLASSIFICATION OF AN ADVERSE EVENT 
 
8.2.3.1 SEVERITY OF EVENT 
 
For adverse events (AEs) not included in the protocol defined grading system, the 
following guidelines will be used to describe severity.  
 
• Mild – Events require minimal or no treatment and do not interfere with the 
participant’s daily activities.  
• Moderate – Events result in a low level of inconvenience or concern with 
the therapeutic measures. Moderate events may cause some interference 
with functioning. 
• Severe – Events interrupt a participant’s usual daily activity and may require 
systemic drug therapy or other treatment. Severe events are usually 
potentially life-threatening or incapacitating.  Of note, the term “severe” 
does not necessarily equate to “serious”.

Protocol : Pro00025982 
07/08/2021 
NIH-FDA Clinical Trial Protocol Template – v1.0 7 Apr 2017 
 
29 
 
 
8.2.3.2 RELATIONSHIP TO STUDY INTERVENTION 
 
All adverse events (AEs) must have their relationship to study intervention 
assessed by the clinician who examines and evaluates the participant based on 
temporal relationship and his/her clinical judgment. The degree of certainty about 
causality will be graded using the categories below. In a clinical trial, the study 
product must always be suspect.  
 
• Related – The AE is known to occur with the study intervention, there is a 
reasonable possibility that the study intervention caused the AE, or there is a 
temporal relationship between the study intervention and event. Reasonable 
possibility means that there is evidence to suggest a causal relationship 
between the study intervention and the AE. 
• Not Related – There is not a reasonable possibility that the administration of 
the study intervention caused the event, there is no temporal relationship 
between the study intervention and event onset, or an alternate etiology has 
been established. 
 
 
8.2.3.3 EXPECTEDNESS  
 
The principal investigator will be responsible for determining whether an adverse 
event (AE) is expected or unexpected.  An AE will be considered unexpected if the 
nature, severity, or frequency of the event is not consistent with the risk 
information previously described for the study intervention. 
 
8.2.4 TIME PERIOD AND FREQUENCY FOR EVENT ASSESSMENT 
AND FOLLOW-UP 
 
 
The occurrence of an adverse event (AE) or serious adverse event (SAE) may 
come to the attention of study personnel during study visits and interviews of a 
study participant presenting for medical care, or upon review by a study monitor. 
 
All AEs including local and systemic reactions not meeting the criteria for SAEs 
will be captured on the appropriate case report form (CRF). Information to be 


68GA-PSMA 11 
Version:5 
Protocol : Pro00025982 
07/08/2021 
NIH-FDA Clinical Trial Protocol Template – v1.0 7 Apr 2017 
 
30 
collected includes event description, time of onset, clinician’s assessment of 
severity, relationship to study product (assessed only by those with the training and 
authority to make a diagnosis), and time of resolution/stabilization of the event. All 
AEs occurring while on study must be documented appropriately regardless of 
relationship. All AEs will be followed to adequate resolution. 
 
Any medical condition that is present at the time that the participant is screened 
will be considered as baseline and not reported as an AE. However, if the study 
participant’s condition deteriorates at any time during the study, it will be recorded 
as an AE.  
 
Changes in the severity of an AE will be documented to allow an assessment of the 
duration of the event at each level of severity to be performed. AEs characterized 
as intermittent require documentation of onset and duration of each episode. 
 
The Principal Investigator  will record all reportable events with start dates 
occurring any time after informed consent is obtained until 7 (for non-serious AEs) 
or 30 days (for SAEs) after the last day of study participation.  At each study visit, 
the investigator will inquire about the occurrence of AE/SAEs since the last visit.  
Events will be followed for outcome information until resolution or stabilization. 
 
 
8.2.5 ADVERSE EVENT REPORTING  
An AE is defined as any untoward medical occurrence in a patient or clinical 
investigation subject administered a pharmaceutical product and which does not 
necessarily have to have a causal relationship with this treatment. An AE can, 
therefore, be any unfavorable and unintended sign (e.g., abnormal laboratory 
finding), symptom, or disease temporally associated with the use of a medicinal 
product or protocol-specified procedure, whether or not considered related to the 
medicinal product or protocol-specified procedure. Any worsening (i.e., any 
clinically significant adverse change in frequency and/or intensity) of a preexisting 
condition that is temporally associated with the study treatment is also an AE. 
Progression of the cancer under study is not considered an AE.  
All AEs that occur after informed consent form signing must be reported by the 
investigator if they cause the subject to be excluded from the Study or are the result 
of a protocol-specified intervention, including but not limited to washout or 
discontinuation of usual therapy, diet, placebo treatment, or a procedure.  


68GA-PSMA 11 
Version:5 
Protocol : Pro00025982 
07/08/2021 
NIH-FDA Clinical Trial Protocol Template – v1.0 7 Apr 2017 
 
31 
 
AEs will not be collected for subjects during the prescreening period as long as 
that subject has not undergone any protocol-specified procedure or intervention. If 
the subject requires a blood draw, fresh tumor biopsy etc., the subject is first 
required to provide consent to the main study and AEs will be captured according 
to guidelines for standard AE reporting.  
The occurrence of AEs should be sought by non-directive questioning of the patient 
at each study visit. AEs may also be detected when they are volunteered by the 
patient during or between visits or through physical examination, laboratory test, or 
other assessments. As far as possible, each AE should be evaluated to determine: 
 
1. Severity grade (CTCAE Grade 1–4) 
2. Duration (Start and end dates or if continuing at the Safety Follow-up Visit) 
3. Relationship to the study treatment (Reasonable possibility that AE is related: No, 
Yes)  
4. Action taken with respect to study or investigational treatment (none, dose 
adjusted, temporarily interrupted, permanently discontinued, hospitalized, 
unknown, not applicable) 
5. Whether medication or therapy was given (no concomitant medication/non-drug 
therapy, concomitant medication/non-drug therapy) 
6. Outcome (not recovered/not resolved, recovered/resolved, recovering/resolving, 
recovered/resolved with sequelae, fatal, unknown) 
7. Whether it is serious, where a SAE is defined as in this protocol. 
 
All AEs should be treated appropriately. Such treatment may include changes in 
study treatment including possible interruption or discontinuation, starting or 
stopping concomitant treatments, changes in the frequency or nature of assessments, 
hospitalization, or any other medically required intervention. Once an AE is detected, 
it should be followed until its resolution, and assessment should be made at each 
visit (or more frequently, if necessary) of any changes in severity, the suspected 
relationship to the study drug, the interventions required to treat it, and the outcome.  
 
8.2.6 SERIOUS ADVERSE EVENT REPORTING  
 
The study clinician will immediately report to the sponsor any serious adverse 
event, whether or not considered study intervention related, including those listed 
in the protocol or investigator brochure and must include an assessment of whether 


68GA-PSMA 11 
Version:5 
Protocol : Pro00025982 
07/08/2021 
NIH-FDA Clinical Trial Protocol Template – v1.0 7 Apr 2017 
 
32 
there is a reasonable possibility that the study intervention caused the event. Study 
endpoints that are serious adverse events (e.g., all-cause mortality) must be 
reported in accordance with the protocol unless there is evidence suggesting a 
causal relationship between the study intervention and the event (e.g., death from 
anaphylaxis). In that case, the investigator must immediately report the event to the 
sponsor. 
 
All serious adverse events (SAEs) will be followed until satisfactory resolution or 
until the site investigator deems the event to be chronic or the participant is stable. 
Other supporting documentation of the event may be requested by the Data 
Coordinating Center (DCC)/study sponsor and should be provided as soon as 
possible. 
 
The Principal Investigator will be responsible for notifying the Food and Drug 
Administration (FDA) of any unexpected fatal or life-threatening suspected 
adverse reaction as soon as possible, but in no case later than 7 calendar days after 
the sponsor's initial receipt of the information.  In addition, the Principal 
Investigator must notify FDA and all participating investigators in an 
Investigational New Drug (IND) safety report of potential serious risks, from 
clinical trials or any other source, as soon as possible, but in no case later than 15 
calendar days after the sponsor determines that the information qualifies for 
reporting. 
 
In case of death, a comprehensive narrative report of the case should be prepared 
by the Investigator together with the SAER. If an autopsy is performed, a copy of 
the autopsy report should be actively sought by the Investigator and sent to the 
Principal Investigator or designee as soon as available. A copy of the autopsy 
report must remain on site with the CRF. 
All deaths will be reported as SAEs regardless of their relationship to disease 
progression and reported via an SAER form from the time of signed informed 
consent until completion of the follow up period. 
A new follow-up SAER form will be filled in by the Investigator if important 
follow-up information (i.e. diagnosis, outcome, causality assessment, results of 
specific investigations) are made available after submission of the initial form. The 
follow up SAER must be signed and dated by the Investigator. The follow-up form 
and any additional source documentation regarding the event will be sent to the 
Principal Investigator, or designee, as described above. 
If a serious medical occurrence or death is reported to the Investigator outside the 
follow up window, which is believed to be related to the administration of the 


68GA-PSMA 11

investigational product, it is the Investigator’s responsibility to report this 
occurrence. 
Such occurrences will be reported using a SAER form or other form of 
communication deemed appropriate by the Investigator. 
 
 
8.2.7 REPORTING EVENTS TO PARTICIPANTS  
If SAEs are seen this study, the informed consent document will be updated with 
pertinent information. 
Participants who had signed previous versions of the informed consent will be 
contacted and asked to sign updated version with new information.

8.3.1 DEFINITION OF UNANTICIPATED PROBLEMS (UP) 
 
 
The Office for Human Research Protections (OHRP) considers unanticipated 
problems involving risks to participants or others to include, in general, any 
incident, experience, or outcome that meets all of the following criteria: 
 
• Unexpected in terms of nature, severity, or frequency given (a) the research 
procedures that are described in the protocol-related documents, such as the 
Institutional Review Board (IRB)-approved research protocol and informed 
consent document; and (b) the characteristics of the participant population 
being studied; 
• Related or possibly related to participation in the research (“possibly 
related” means there is a reasonable possibility that the incident, experience, 
or outcome may have been caused by the procedures involved in the 
research); and

• Suggests that the research places participants or others at a greater risk of 
harm (including physical, psychological, economic, or social harm) than was 
previously known or recognized. 
 
 
8.3.2  UNANTICIPATED PROBLEM REPORTING  
 
The investigator will report unanticipated problems (UPs) to the reviewing 
Institutional Review Board (IRB) and to the Data Coordinating Center (DCC)/lead 
principal investigator (PI). The UP report will include the following information: 
 
• Protocol identifying information: protocol title and number, PI’s name, and 
the IRB project number; 
• A detailed description of the event, incident, experience, or outcome;  
• An explanation of the basis for determining that the event, incident, 
experience, or outcome represents an UP;  
• A description of any changes to the protocol or other corrective actions that 
have been taken or are proposed in response to the UP. 
 
To satisfy the requirement for prompt reporting, UPs will be reported using the 
following timeline:   
 
• UPs that are serious adverse events (SAEs) will be reported to the IRB and 
to the DCC/study sponsor within <insert timeline in accordance with policy> 
of the investigator becoming aware of the event.  
• Any other UP will be reported to the IRB and to the DCC/study sponsor 
within <insert timeline in accordance with policy> of the investigator 
becoming aware of the problem.  
• All UPs should be reported to appropriate institutional officials (as required 
by an institution’s written reporting procedures), the supporting agency head 
(or designee), and the Office for Human Research Protections (OHRP) 
within <insert timeline in accordance with policy> of the IRB’s receipt of 
the report of the problem from the investigator.

9 STATISTICAL CONSIDERATIONS  
 
 
9.1 SAMPLE SIZE DETERMINATION 
 
Sample size for this pilot study was not statistically determined. Instead it was 
decided that up to 80 evaluable study subjects with prostate cancer are sufficient to 
adequately evaluate the tissue distribution of 185±74 MBq (5±2 mCi) 68Ga-
PSMA-11 PET/CT imaging in tumor and non-tumorous regions of the prostate 
and/or pelvic lymph nodes (as determined by histopathology) in patients 
undergoing standard of care prostatectomy and/or pelvic lymph node dissection. 
Further, present calculations from a suitable range of assumptions to gauge the 
robustness of the proposed sample size. 
 
 
 
9.2 POPULATIONS FOR ANALYSES 
 
The enrolled population will consist of all subjects who provided written informed 
consent and received the  dosing of study drug. 
 
9.3 STATISTICAL ANALYSES 
 
9.3.1 GENERAL APPROACH 
 
The detailed prospective procedures for the final data analysis are described in the 
Statistical Analysis Plan (SAP). Any changes in the original statistical 
methodology will be documented in the SAP. Descriptive statistics for all 
continuous variables (N, mean, standard deviation, minimum, median, and 
maximum) or for categorical variables (counts, percentages) will be generated and 
presented as appropriate.

risks are given to the participant and written documentation of informed consent is 
required prior to starting intervention/administering study intervention.   
 
 
10.1.1.2 
CONSENT PROCEDURES AND DOCUMENTATION 
 
Informed consent is a process that is initiated prior to the individual’s agreeing to 
participate in the study and continues throughout the individual’s study 
participation. Consent forms will be Institutional Review Board (IRB)-approved 
and the participant will be asked to read and review the document. The investigator 
will explain the research study to the participant and answer any questions that 
may arise. A verbal explanation will be provided in terms suited to the 
participant’s comprehension of the purposes, procedures, and potential risks of the

study and of their rights as research participants.  Participants will have the 
opportunity to carefully review the written consent form and ask questions prior to 
signing. The participants should have the opportunity to discuss the study with 
their family or surrogates or think about it prior to agreeing to participate. The 
participant will sign the informed consent document prior to any procedures being 
done specifically for the study. Participants must be informed that participation is 
voluntary and that they may withdraw from the study at any time, without 
prejudice. A copy of the informed consent document will be given to the 
participants for their records. The informed consent process will be conducted and 
documented in the source document (including the date), and the form signed, 
before the participant undergoes any study-specific procedures. The rights and 
welfare of the participants will be protected by emphasizing to them that the 
quality of their medical care will not be adversely affected if they decline to 
participate in this study.  
 
10.1.2 
STUDY DISCONTINUATION AND CLOSURE 
 
This study may be temporarily suspended or prematurely terminated if there is 
sufficient reasonable cause.  Written notification, documenting the reason for study 
suspension or termination, will be provided by the suspending or terminating party 
to <study participants, investigator, funding agency, the Investigational New Drug 
(IND) or Investigational Device Exemption (IDE) sponsor and regulatory

10.1.3 
CONFIDENTIALITY AND PRIVACY  
 
 
Participant confidentiality and privacy is strictly held in trust by the participating 
investigators, their staff, and the sponsor(s) and their interventions. This 
confidentiality is extended to cover testing of biological samples and genetic tests 
in addition to the clinical information relating to participants. Therefore, the study 
protocol, documentation, data, and all other information generated will be held in 
strict confidence. No information concerning the study or the data will be released 
to any unauthorized third party without prior written approval of the sponsor.  
 
All research activities will be conducted in as private a setting as possible. 
 
The study monitor, other authorized representatives of the sponsor, representatives 
of the Institutional Review Board (IRB), regulatory agencies or pharmaceutical 
company supplying study product may inspect all documents and records required 
to be maintained by the investigator, including but not limited to, medical records 
(office, clinic, or hospital) and pharmacy records for the participants in this study. 
The clinical study site will permit access to such records. 
 
The study participant’s contact information will be securely stored at each clinical 
site for internal use during the study. At the end of the study, all records will 
continue to be kept in a secure location for as long a period as dictated by the 
reviewing IRB, Institutional policies, or sponsor requirements. 
 
Study participant research data, which is for purposes of statistical analysis and 
scientific reporting, will be transmitted to and stored at Houston Methodist 
Department of Urology. This will not include the participant’s contact or 
identifying information. Rather, individual participants and their research data will 
be identified by a unique study identification number. The study data entry and 
study management systems used by clinical sites and by Houston Methodist  
research staff will be secured and password protected. At the end of the study, all 
study databases will be de-identified and archived at Houston Methodist Research 
Institute.

QUALITY ASSURANCE AND QUALITY CONTROL 
 
Subject data will be collected on source documents and transcribed on pre-printed 
CRFs provided by the Principal Investigator. The data on each CRF will be legibly 
handwritten with a ballpoint pen or typed. The Principal Investigator or his or her 
authorized designee will sign the CRF on the appropriate page(s) to verify that the 
data on the CRF were reviewed. Records of subjects, source documents, 
monitoring visit logs, data correction forms, CRFs, inventory of study product, 
regulatory documents (e.g., protocol and amendments, IRB/IEC correspondence 
and approvals, approved and signed informed consent forms, Investigator’s 
Agreement, clinical supplies receipts, and distribution and return records), and 
other Principal Investigator correspondence pertaining to the study will be kept in 
the appropriate study files at the site. Source documents include all recordings and 
observations or notations of clinical activities and all reports and records necessary 
for the evaluation and reconstruction of the clinical study. These records will be 
retained in a secure file for the period required by the institution or site policy. 
Quality control (QC) procedures will be implemented beginning with the data 
entry system and data QC checks that will be run on the database will be 
generated. Any missing data or data anomalies will be communicated to the site(s) 
for clarification/resolution.

Data collection is the responsibility of the clinical trial staff at the site under the 
supervision of the site investigator. The investigator is responsible for ensuring the 
accuracy, completeness, legibility, and timeliness of the data reported. 
 
All source documents should be completed in a neat, legible manner to ensure 
accurate interpretation of data.   
 
Hardcopies of the study visit worksheets will be provided for use as source 
document worksheets for recording data for each participant enrolled in the study.  
Data recorded in the electronic case report form (eCRF) derived from source 
documents should be consistent with the data recorded on the source documents.  
 
Clinical data (including adverse events (AEs), concomitant medications, and 
expected adverse reactions data) and clinical laboratory data will be entered into 
Red Cap, a 21 CFR Part 11-compliant data capture system provided by Houston 
Methodist. The data system includes password protection and internal quality 
checks, such as automatic range checks, to identify data that appear inconsistent, 
incomplete, or inaccurate. Clinical data will be entered directly from the source 
documents. 
 
10.1.8.2 
STUDY RECORDS RETENTION  
 
Study documents should be retained for a minimum of 2 years after the last 
approval of a marketing application in an International Conference on 
Harminosation (ICH) region and until there are no pending or contemplated 
marketing applications in an ICH region or until at least 2 years have elapsed since 
the formal discontinuation of clinical development of the study intervention. These 
documents should be retained for a longer period, however, if required by local 
regulations. No records will be destroyed without the written consent of the 
sponsor, if applicable. It is the responsibility of the sponsor to inform the 
investigator when these documents no longer need to be retained. 
 
10.1.9 
PROTOCOL DEVIATIONS  
 
A protocol deviation is any noncompliance with the clinical trial protocol, 
International Conference on Harmonisation Good Clinical Practice (ICH GCP), or 
Manual of Procedures (MOP) requirements. The noncompliance may be either on 
the part of the participant, the investigator, or the study site staff. As a result of 


68GA-PSMA 11

Protocol : Pro00025982 
07/08/2021 
NIH-FDA Clinical Trial Protocol Template – v1.0 7 Apr 2017 
 
42 
deviations, corrective actions are to be developed by the site and implemented 
promptly.  
 
These practices are consistent with ICH GCP:  
• 4.5 Compliance with Protocol, sections 4.5.1, 4.5.2, and 4.5.3  
• 5.1 Quality Assurance and Quality Control, section 5.1.1  
• 5.20 Noncompliance, sections 5.20.1, and 5.20.2.  
 
It is the responsibility of the site investigator to use continuous vigilance to identify 
and report deviations within 5 working days of identification of the protocol 
deviation, or within 5 working days of the scheduled protocol-required activity.  
All deviations must be addressed in study source documents, reported to Program 
Official Data Coordinating Center or sponsor.  Protocol deviations must be sent to 
the reviewing Institutional Review Board (IRB) per their policies. The site 
investigator is responsible for knowing and adhering to the reviewing IRB 
requirements.  
 
 
10.1.10 
PUBLICATION AND DATA SHARING POLICY 
 
This study will be conducted in accordance with the following publication and data 
sharing policies and regulations: 
 
National Institutes of Health (NIH) Public Access Policy, which ensures that the 
public has access to the published results of NIH funded research. It requires 
scientists to submit final peer-reviewed journal manuscripts that arise from NIH 
funds to the digital archive PubMed Central upon acceptance for publication. 
 
This study will comply with the NIH Data Sharing Policy and Policy on the 
Dissemination of NIH-Funded Clinical Trial Information and the Clinical Trials 
Registration and Results Information Submission rule. As such, this trial will be 
registered at ClinicalTrials.gov, and results information from this trial will be 
submitted to ClinicalTrials.gov. In addition, every attempt will be made to publish 
results in peer-reviewed journals.  Data from this study may be requested from 
other researchers 2 years after the completion of the primary endpoint by 
contacting the Principal Investigator.
