status, and lumbar puncture results made available to this study to allow for analysis and 
comparison. This study hopes to recruit roughly 80 percent amyloid positive subjects, and 20 
percent amyloid negative subjects from the BIOCARD study. Amyloid positivity will be 
determined by quantification of the BIOCARD PiB scan, and a list of patients for recruitment 
blinded to amyloid status will be provided to the site. Subjects’ amyloid status will not be revealed 
as a part of recruitment or inclusion for this study.  
 
Screening assessments may take place over several days, within 90 days of the flortaucipir (18F) 
Positron Emission Tomography (PET) scan, and will include demographics, medical history and 
concomitant medications, a physical exam, and a safety evaluation. Additionally, participants will 
have an ECG with results reviewed prior to the initial flortaucipir (18F) imaging visit. If the ECG 
was performed within the last six to twelve months of the 18F -AV-1451 PET Imaging Visit and is 
available for review, the ECG does not need to be repeated. Subjects may be permitted to return for 
the flortaucipir (18F) PET scan after the 90 day window with sponsor approval if the investigator 
does not recognize any significant medical changes.  
 
Subjects who qualify for the study will return to the clinic at a later date for the flortaucipir (18F) 
PET imaging visit. For the flortaucipir (18F) PET imaging visit, an intravenous catheter will be 
placed for IV administration of flortaucipir (18F) injection.  Subjects will receive a single IV bolus 
injection with a target dose of 370 MBq (10 mCi) of flortaucipir (18F) injection followed by a saline 
flush. At approximately 75 minutes following injection, a continuous 30-minute brain scan will 
begin. Adverse events will be monitored continuously during the imaging session. A physician or a 
licensed/credentialed medical professional (i.e., a PET technologist, imaging center nurse or a 
regional equivalent) designated by the site principal investigator must assess or evaluate the subject 
prior to injection and prior to discharge from the imaging center. If a designee performs this 
activity, a physician must be available to provide medical consultation. 
 
A follow-up phone call to the subject, or informant where applicable, will be conducted between 2 
or 3 business days of each imaging day, but not before 48 hours post-injection, to confirm subject 
well-being and to collect information about any new adverse events.  If both of these days are not 
business days, the follow-up phone call can occur the following business day. 
 
Assessments and Endpoints: 
All subjects will have a screening visit, a flortaucipir (18F) PET imaging visit, and a follow-up 
phone call after the imaging visit.  
 
Details of additional assessments that will be performed at each visit are detailed in Section 7.1.   
Statistical Methods:   
Exploratory analyses will examine the relationship among flortaucipir (18F) SUVr measurements, 
cognitive and neuropsychiatric measurements, and other collected biomarkers in subjects.

1. INTRODUCTION  
Of the 2 pathological protein deposits that are the hallmark of Alzheimer’s disease 
(AD), beta- amyloid (Aβ) is thought to accumulate very early in the disease process 
and is frequently observed in elderly subjects with no clinical symptoms, a 
condition that may represent a preclinical phase of the disease. Furthermore, as a 
biomarker, Aβ plaques as seen on PET amyloid imaging appear to plateau in 
intensity early in the symptomatic phase of the disease.  
In contrast to Aβ deposits, the density and distribution in the brain of 
phosphorylated tau, in the form of neocortical tangle pathology, has been shown in 
autopsy studies to be increased with AD-related cognitive impairment and appears 
to correlate with overall evidence of neurodegeneration across the entire spectrum 
of the illness (Duyckaerts et al. 1987; Nelson et al. 2012). Thus, an understanding 
of the onset and progression of tau pathology in relation to amyloid pathology and 
cognitive change may be critical to understanding the course of the disease.  
Flortaucipir (18F)  (originally named [F-18]T807 by Siemens Molecular Imaging 
Biomarker Research group) has been developed as a positron emitting 
radiopharmaceutical for in vivo imaging of tau protein aggregates (Xia et al., 2013). 
Autoradiography results using tissue sections from human brains showed a strong 
signal in the grey matter of cortical slices from tau positive brains but weak or no 
binding in tau negative, Aβ positive, or tau and A negative tissue. Scatchard analysis 
based on this heterogeneous autoradiography assay yielded an estimated Kd of 15nM. 
A saturation binding experiment using purified Paired Helical Fragment Tau isolated 
brains of AD patients yielded a Kd value of 0.54 nM. 
An updated summary of preclinical and clinical experience pertaining to safety of 
flortaucipir (18F) can be found in the investigator’s Brochure. Briefly, preclinical 
toxicity studies of 19F-AV-1451 (non-radioactive flortaucipir (18F), “AV-1451”) 
showed a good safety profile with no observable effects at high multiples of the 
intended maximum human dose. AV-1451 was positive in the in vitro hERG assay. 
However, the cardiovascular assessments performed during the dog toxicology 
studies showed no evidence that AV-1451 prolongs the QT interval at high multiples 
of relevant clinical doses, and therefore risk of QT prolongation is not included in the 
risk profile. Nonetheless, until sufficient human cardiovascular safety data are 
available, clinical studies will exclude subjects with a history of risk factors for 
Torsades de Pointes and subjects taking drugs known to prolong the QT interval. 
Human dosimetry results for flortaucipir (18F) showed both hepatobiliary and renal 
excretion, and total effective dose similar to other approved F-18 
radiopharmaceuticals. The organs of the gastrointestinal tract (upper large intestine, 
small intestine and liver) received the greatest exposure. The whole body effective 
dose for a 10 mCi (370 MBq) dose of flortaucipir (18F) was calculated to be 
8.70 mSv. In human clinical studies so far, flortaucipir (18F) is generally well-
tolerated with a low incidence of mild and transient adverse events. 
Preliminary image assessment showed tracer deposition on brain PET scans to be 
consistent with that expected for a tracer of aggregated tau protein. Flortaucipir (18F)

initially entered the brain and was subsequently eliminated from the brain in normal 
subjects yielding only a diffuse pattern of background activity, whereas a regionally 
distinct gray matter distribution of increased tracer retention was observed in subjects 
with high probability AD. Interim cross-sectional efficacy results (study flortaucipir 
(18F) -A05) show a distribution pattern of aggregated tau across diagnostic groups 
paralleling that hypothesized on the basis of postmortem evaluation (Braak et al., 
2006).   
A relatively small number of subjects in the ongoing A05 study presented cognitively 
as clinically normal with elevated brain amyloid. It is important to evaluate additional 
subjects of this type to obtain information regarding the presence/onset of tau 
pathology because clinically normal amyloid positive subjects have been 
hypothesized to represent the earliest preclinical stage of AD (Sperling et al., 2011). 
The present study will obtain flortaucipir (18F) tau PET scans in 100 clinically normal 
subjects from the BIOCARD study that have been identified as having elevated brain 
amyloid by PET or CSF assays.  
 
2. TRIAL OBJECTIVES 
 
The primary objectives of this study are: 
 To evaluate imaging characteristics of flortaucipir (18F) in respect to brain 
amyloid status in subjects who are enrolled in the BIOCARD study 
 To examine the relationship between cognitive and functional performance, other 
biomarker data, and tau deposition as measured by flortaucipir (18F) uptake in 
clinically normal subjects 
 
A secondary objective of this study is: 
 To expand the flortaucipir (18F) safety database.

5. INVESTIGATIONAL PLAN 
 
 
  
5.1 Overall Design and Plan of Trial 
This is a phase I study that will evaluate imaging characteristics of flortaucipir 
(18F) in subjects enrolled in the BIOCARD study.  
 
Subjects enrolled in the BIOCARD study will be contacted to participate and 
must provide informed consent before starting any AV-1451-A20 study 
procedures. In addition to consenting to study procedures, participants will 
consent to have BIOCARD-related data, including Magnetic Resonance Imaging 
(MRI) images/data, laboratory data, medical and neuropsychological assessments, 
as well as amyloid status, and lumbar puncture results, made available to this 
study to allow for analysis and comparison. This study hopes to recruit roughly 80 
percent amyloid positive subjects, and 20 percent amyloid negative subjects from 
the BIOCARD study. Amyloid positivity will be determined by quantification of 
the BIOCARD PiB scan, and a list of patients for recruitment blinded to amyloid 
status will be provided to the site. Subjects’ amyloid status will not be revealed as 
a part of recruitment or inclusion for this study.  
 
Screening assessments may take place over several days, within 90 days of the 
flortaucipir (18F) Positron Emission Tomography (PET) scan, and will include 
demographics, medical history and concomitant medications, a physical exam, 
and a safety evaluation. Additionally, participants will have an ECG with results 
reviewed prior to the initial flortaucipir (18F) imaging visit. If the ECG was

performed within the last six to twelve months of the 18F -AV-1451 PET Imaging 
Visit and is available for review, the ECG does not need to be repeated. Subjects 
may be permitted to return for the flortaucipir (18F) PET scan after the 90 day 
window with sponsor approval if the investigator does not recognize any 
significant medical changes.  
 
Subjects who qualify for the study will return to the clinic at a later date for the 
flortaucipir (18F) PET imaging visit. For the flortaucipir (18F) PET imaging visit, 
an intravenous catheter will be placed for IV administration of flortaucipir (18F) 
injection.  Subjects will receive a single IV bolus injection with a target dose of 
370 MBq (10 mCi) of flortaucipir (18F) injection followed by a saline flush. At 
approximately 75 minutes following injection, a continuous 30-minute brain scan 
will begin. Adverse events will be monitored continuously during the imaging 
session. A physician or a licensed/credentialed medical professional (i.e., a PET 
technologist, imaging center nurse or a regional equivalent) designated by the site 
principal investigator must assess or evaluate the subject prior to injection and 
prior to discharge from the imaging center. If a designee performs this activity, a 
physician must be available to provide medical consultation. 
 
A follow-up phone call to the subject, or informant where applicable, will be 
conducted between 2 or 3 business days of each imaging day, but not before 48 
hours post-injection, to confirm subject well-being and to collect information 
about any new adverse events.  If both of these days are not business days, the 
follow-up phone call can occur the following business day. 
 
5.2 Planned Dosage and Duration of Treatment 
 
5.2.1 Dosage and Administration 
All subjects will receive a single IV bolus administration of approximately 
370 MBq (10 mCi) of flortaucipir (18F) injection. 
 
5.2.2 Rationale for Dosage  
Flortaucipir (18F) will be administered IV in a radioactive dose of 370 MBq 
(10 mCi) with a maximum human dose (MHD) limited to 20 µg of compound 
by weight.  This dose is 150 fold lower than the NOAEL observed in the rat 
single dose toxicity study and is 50 fold lower than the NOAEL observed in 
the rat and dog repeat dose toxicity studies. 
 
Human dosimetry has been obtained in nine subjects. The results estimated an 
Effective Dose of 8.92 mSv for an anticipated 370 MBq (10 mCi) injection 
and is comparable to the effective dose of approved 18F-labeled compounds 
such as FDG and florbetapir F 18 injection. 
 
The proposed dose has been shown to have acceptable image quality in 
previous human studies. No treatment related adverse events have been 
reported using this regimen.

5.3 Selection of Subjects 
 
5.3.1 Inclusion Criteria 
All subjects must meet all of the following criteria to enroll in this trial: 
 
1. Male or females that have consented and are currently enrolled in the 
BIOCARD protocol 
2. Can tolerate PET scan procedures; and 
3. Have the ability to provide informed consent for study procedures (if the 
patient is ineligible to give informed consent, based on local standards, the 
patient’s legal representative may consent on behalf of the patient, but the 
patient must still confirm assent). 
 
5.3.2 Exclusion Criteria 
Subjects will be excluded from enrollment if they: 
1. Has any condition by history or abnormal findings on physical 
examination or screening tests that, in the investigator’s opinion, could 
increase risk to the participant, limit the participant’s ability to tolerate 
the experimental procedures (e.g., chronic back pain which might limit 
the ability to lie still during the scanning procedures), or interfere with 
analysis of the data.   
2. Has a history of risk factors for Torsades de Pointes or is taking 
medications known to prolong QT interval. A list of restricted 
medications will be provided. 
3. Have ECG obtained prior to the initial flortaucipir (18F) scan that in the 
opinion of the investigator is clinically significant with regard to the subject’s 
participation in the study. Bazett’s corrected QT (QTcB) interval must be 
evaluated and must not exceed 458 msec in males, or 474 msec in females.  
4. Are females of childbearing potential who are not surgically sterile, 
not refraining from sexual activity or not using reliable methods of 
contraception. Females of childbearing potential must not be pregnant 
(negative serum β-hCG at the time of screening and negative urine β-
hCG on imaging day) or breastfeeding at screening. Females must agree 
to avoid becoming pregnant, and refrain from sexual activity or to use 
reliable contraceptive methods for 24 hours following administration of 
flortaucipir (18F). 
5. Has hypersensitivity to flortaucipir (18F) or any of its excipients. 
6. Have a current clinically significant infectious disease, endocrine or 
metabolic disease, pulmonary, renal or hepatic impairment, or cancer that the 
investigator believes would affect study participation or scan results; 
7. Have had a non-study related radiopharmaceutical imaging or treatment 
procedure within 7 days prior to the flortaucipir (18F) imaging session;  
8. In the opinion of the investigator, are otherwise unsuitable for a study of 
this type.

a. Prior and Concomitant Therapy 
 
Except as noted in the exclusion criteria, all medications (prescription or over-the-
counter) that have been started prior to screening may be continued during the 
course of the trial.  All medications, including investigational medications that are 
continued from the start of the trial, or that are started during the trial (other than 
the study medication), must be documented on the Concomitant Medication Page 
of the electronic Case Report Form (eCRF).   
 
5.5 Removal of Subjects from Trial 
 
Subjects must be removed from the trial if: 
1. Informed consent is withdrawn; or 
2. The investigator or the sponsor believes it is in the best interest of the subject 
to be removed from the trial.   
Subjects may be withdrawn from the trial if a SAE occurs. The date and reason 
for discontinuation should be noted on the eCRF. Subjects who discontinue 
prematurely should be seen for a final evaluation.  
 
5.6 Premature Termination of Trial/Closure of Center 
 
The sponsor may discontinue the trial at any time.  Reasons for discontinuation of 
the trial may include, but are not limited to, new information on safety or efficacy, 
requests from regulatory authorities, or changes in business priorities.  Additional 
reasons for center closure may include, but are not limited to, excessive protocol 
violations, inadequate regard for subject safety, failure to follow recommended 
procedures (e.g., documentation), failure or inability to accommodate 
Avid/Contract Research Organization (CRO) monitors or to provide required 
access to data and source documents, staff turnover, inadequate staffing, and 
inadequate enrollment.  Except in cases affecting subject safety, the investigator 
may complete final study evaluations for ongoing subjects. In all cases of center, 
or study termination, appropriate steps will be taken to ensure the safety of study 
subjects. 
 
6. WARNINGS/PRECAUTIONS 
 
The most up-to-date and complete information regarding the use of flortaucipir (18F) 
injection can be found in the investigator's brochure.  
 
In brief, flortaucipir (18F) injection is an experimental imaging agent that will be used 
at relatively low (tracer) doses.  Because flortaucipir (18F) injection is under clinical 
investigation, it is recommended that subjects receiving flortaucipir (18F) injection be 
followed closely by means of adverse event reporting.

7. PROCEDURES AND METHODS 
 
7.1 Assessment Periods (See Section 11.2, Trial Flow Chart) 
       
 
The study will consist of the following sequence of activities:  
 
7.1.1 Screening Visit: 
Subjects currently enrolled in the BIOCARD study protocol will be contacted 
to participate. Screening assessments may take place over several days, within 
90 days of the flortaucipir (18F) PET scan, and will include: 
 Informed Consent will take place before any AV-1451-A20 study 
procedures; 
 Demographics (birth year, gender, race, ethnicity, education, alcohol, drug 
use and smoking); 
 Medical history and concomitant medications; 
 For women of childbearing potential, a negative serum pregnancy test 
must be obtained at the screening visit.  
 A physician will see the subject during the screening assessments.   
 An ECG will be performed to assess the participant’s cardiac status. If an 
ECG was performed within the last 12 months of the flortaucipir (18F) 
PET Imaging Visit and is available for review, the ECG does not need to 
be repeated.  
 
7.1.2 Imaging Visit(s)  
 
Flortaucipir (18F) PET Imaging Visit 
 A physician or a licensed/credentialed medical professional (i.e., a PET 
technologist, imaging center nurse or a regional equivalent) designated by 
the site principal investigator must assess or evaluate the subject prior to 
administration of flortaucipir (18F) injection to determine if they are still 
suitable to undergo the scan. If a designee performs this activity, a 
physician must be available to provide medical consultation; 
 For women of childbearing potential, a negative urine pregnancy test must 
be obtained on the day of flortaucipir (18F) dose administration; 
 Subjects will receive a single IV bolus injection target dose of 370 MBq 
(10 mCi) of flortaucipir (18F) injection followed by a saline flush.  
 At approximately 75 minutes following injection, a continuous 30-minute 
brain scan will begin;   
 The injection site will be observed for excessive inflammation or damage 
to the surrounding tissue where the dose was injected; 
 Adverse events will be continuously monitored during the flortaucipir 
(18F) PET imaging visit. Subjects who experience an adverse event will 

BIOCARD Protocol 20Jan2017 Amendment 1  
 
 
Confidential 
 
Page 18 of 30 
 
not be discharged from the imaging center until the event has resolved or 
stabilized;  
 A physician or a licensed/credentialed medical professional (i.e., a PET 
technologist, imaging center nurse or a regional equivalent) designated by 
the site principal investigator must assess or evaluate the subject prior to 
discharge from the imaging center to evaluate the subject’s readiness for 
discharge. If a designee performs this activity, a physician must be 
available to provide medical consultation; and 
 A follow-up phone call to the subject, or informant where applicable, will 
be conducted within 2 or 3 business days of the imaging day, but not 
before 48 hours post-injection, to confirm subject well-being and to collect 
information about any new adverse events.  If both of these days are not 
business days, the follow-up phone call can occur the following business 
day. 
 
  
7.2 Observations and Measurements 
   
Informed Consent 
 
Potential subjects will be allowed to read a written informed consent form.  The 
principal investigator, or designee, will explain all study procedures, risks, and 
alternative therapies to the subject.  The subject will have an opportunity to have 
all questions answered.  The appropriate parties will then sign and date the 
informed consent form, indicating willingness to participate in the study (see 
Section 7.5). A copy of the signed informed consent will be given to the subject.  
 
All informed consent forms must be approved by Avid or designee, and by the 
appropriate Institutional Review Board (IRB) prior to use. 
 
Medical History  
The investigator or designee will obtain an updated history at the screening visit. 
 Relevant demographic information  
 Review of body systems 
 Social history 
 Medical and surgical history, including medical care for head trauma 
 Concurrent medications 
Whenever possible, the medical history will be confirmed by medical records. 
Electrocardiogram (ECG) 
A resting 12-lead electrocardiogram will be recorded as part of the screening visit, 
unless an ECG was performed within twelve months of the flortaucipir (18F) PET 
Imaging Visit and is available for review. 
 
Physician Visit 
A physician must see the subject during the screening visit. A physician or a 
licensed/credentialed medical professional (i.e., a PET technologist, imaging 

BIOCARD Protocol 20Jan2017 Amendment 1  
 
 
Confidential 
 
Page 19 of 30 
 
center nurse or a regional equivalent) designated by the site principal investigator 
must assess or evaluate the subject prior to administration of flortaucipir (18F) 
injection and prior to discharge from the imaging center. If a designee performs 
this activity, a physician must be available to provide medical consultation. At 
discharge, the physician or licensed/credentialed medical professional should 
review all safety data and briefly examine/query the subject regarding potential 
adverse events or other treatment issues.   
 
Pregnancy Testing  
 Serum beta hCG, qualitative:  performed at screening for females of 
childbearing potential (defined as pre-menopausal, less than 2 years post-
menopausal or not surgically sterile).  A serum pregnancy test may also be 
obtained prior to injection at the imaging visit if required by the local site. 
 Urine beta hCG: performed at the flortaucipir (18F)  imaging visit prior to 
injection for females of childbearing potential (defined as pre-menopausal, 
less than 2 years post-menopausal or not surgically sterile). 
 
 
  
7.3 Protocol for Image Collection 
 
The sponsor will prepare and distribute imaging manuals for flortaucipir (18F) 
image acquisition parameters and transmission procedures prior to site initiation.   
 
 
  
7.4 Good Clinical Practice and Monitoring 
 
All clinical studies performed under the direction of Avid/CRO will be conducted 
in accordance with applicable regulatory requirements and International 
Conference on Harmonization (ICH) Good Clinical Practice (GCP) and 
Avid/CRO Standard Operating Procedures (SOP).  
This includes: 
1. IRB approval:  An investigation will be initiated at a study site only after the 
IRB for that study site has given their written approval of the protocol and 
informed consent;    
2. Informed Consent:  Study procedures will not be initiated until the subject 
signs the informed consent form;   
3. Recording and monitoring of adverse events as outlined in Section 7.7.3 
including the notification of study site clinical investigators, local IRBs and 
the FDA regarding serious adverse event; 
4. Avid RP’s obligation to monitor the participating center on a regular basis; 
and 
5. The termination of a center or the trial if conditions apply, as outlined in 
Section 5.6. 
 

BIOCARD Protocol 20Jan2017 Amendment 1  
 
 
Confidential 
 
Page 20 of 30 
 
 
  
7.5 Informed Consent and Subject Information 
 
Potential subjects will be allowed to read a written informed consent form.  The 
principal investigator or designee will explain all study procedures, risks, and 
alternative therapies.  The subject will have an opportunity to have all questions 
answered by a physician.  The subject will then sign and date the informed 
consent form, indicating willingness to participate in the study.   
 
If the subject is not capable of giving consent, consent may be given by a legally 
authorized representative.  However, it is expected that all subjects entering this 
study should at least have the capacity to understand that they are engaging in a 
research study and should affirm that they do not object to participating, by 
signing on the Subject Assent line of the consent form.  If the legal guardian is 
also the informant, the guardian must still sign the informant line of the form, 
indicating their own willingness to participate as an informant. 
 
All informed consent forms must be approved by Avid or designee, and by the 
appropriate Institutional Review Board (IRB).  No study related procedures shall 
be performed prior to completion of the informed consent process, and signing of 
the consent form.  A copy of the signed informed consent should be given to the 
patient for their records. 
 
 
  
7.6 Documentation 
 
Flortaucipir (18F) PET scans will be saved in an appropriate electronic format as 
specified in the imaging manuals.  A copy of all scans, including the MRI scans 
conducted per BIOCARD study protocol, will be saved at the site/imaging center 
and a copy of each will be forwarded to the sponsor described in the imaging 
manuals.  All other data required by the protocol will be recorded in the eCRFs.  
All data in the eCRFs will be substantiated by “source documents,” which consist 
of the subject’s medical files, laboratory result sheets, ECG tracings, etc.  All 
source documentation must be available to Avid, and its designees.  Completed 
source documents and eCRFs may need to be made available and complete for an 
audit by the FDA, other international regulatory authorities, or Avid at any time.  
The eCRFs and all other records must be filed in accordance with applicable laws 
and regulations (see Section 10.6). 
 
 
  
7.7 Adverse Events (AE) 
 
Avid’s standards for recording and reporting adverse events (AEs) are to be 
followed regardless of applicable regulatory requirements that may be less 
stringent.  All AEs must be fully recorded on the adverse event eCRFs. 
Investigators will be instructed to report to Avid, or its designee, their assessment 
of the potential relatedness of each AE to study drug or protocol procedure via 
electronic data entry.  If a patient’s treatment is discontinued as a result of an AE, 
study site personnel must clearly report to Avid, or its designee, via electronic 

BIOCARD Protocol 20Jan2017 Amendment 1  
 
 
Confidential 
 
Page 21 of 30 
 
data entry the circumstances and data leading to any such discontinuation of 
treatment. In cases where the investigator notices an unanticipated benefit to the 
patient, study site personnel should report “unexpected benefit” with the actual 
event term to Avid, or its designee (for example, the complete actual term would 
be “unexpected benefit- sleeping longer”). 
 
Signs and symptoms of each AE should be described in detail (e.g., start and stop 
dates/time, severity/intensity, relationship to study drug, action taken, and event 
resolution).  Additionally, any clinically significant findings from study 
procedures including those that result in a diagnosis should be reported as an AE 
to Avid, or its designee.  
 
7.7.1 Adverse Event Monitoring 
  
Each patient must be carefully monitored for adverse events.  This includes 
clinical laboratory test variables.  An assessment must be made of the 
severity/intensity and relationship to the administration of the study drug. 
 
7.7.2 Adverse Event Definitions 
Adverse Events 
 
An adverse event is any undesirable experience occurring to a subject during a 
clinical trial, whether or not considered related to the study drug. 
 
For reporting purposes, Avid will distinguish among pre-existing conditions, 
trial-emergent adverse events and treatment-emergent adverse events.   
 
Pre-existing conditions (i.e., undesirable experiences, signs or symptoms that 
begin prior to the Screening Visit) will be recorded on the medical history 
eCRF pages. During the study, site personnel will record any change in the 
condition(s) and occurrence and nature of any AEs.  Signs and symptoms that 
are believed to be due to the pre-existing condition(s) (started prior to dose of 
study medication) do not have to be recorded in the AEs section of the eCRF, 
unless there is an increase in frequency and severity. 
 
Trial-emergent adverse events are undesirable experiences, signs or symptoms 
that begin, or worsen in intensity or frequency, after the informed consent, and 
prior to administration of the study drug at the imaging visit.  
 
 
Treatment-emergent adverse events are any untoward medical occurrence 
associated with the use of a drug in humans, whether or not considered drug 
related.  For the purposes of this study, untoward medical occurrences will be 
considered associated with the use of flortaucipir (18F), and thus be reported as 
adverse events, if they occur within 48 hours after flortaucipir (18F) 
administration.  

BIOCARD Protocol 20Jan2017 Amendment 1  
 
 
Confidential 
 
Page 22 of 30 
 
 
The end of study, for the purpose of adverse event reporting, is defined as 48 
hours after the last administration of flortaucipir (18F). 
 
Serious Adverse Event (SAE) 
 
A SAE is an AE that results in one of the following outcomes or constitutes 
one of the following events: 
 Death; 
 Initial or prolonged inpatient hospitalization (other than that required by 
protocol; “social hospitalization” or any hospitalization for non-medical 
reasons does not constitute a SAE); 
 A life-threatening experience (that is, immediate risk of dying); 
 Persistent or significant disability/incapacity; 
 Congenital anomaly/birth defect; 
 Considered significant by the investigator for any other reason. 
                                          
Important medical events that may not result in death, be life-threatening, or 
require hospitalization may be considered serious adverse drug events when, 
based upon appropriate medical judgment, they may jeopardize the patient 
and may require medical or surgical intervention to prevent one of the 
outcomes listed in this definition. 
 
 
Unexpected Adverse Event 
 
An unexpected adverse event is an adverse event not previously reported or an 
adverse event that occurs with specificity, severity or frequency that is not 
consistent with the current IB. 
 
Relationship to Study Drug 
 
Investigators will be instructed to report their assessment of the potential 
relatedness of each adverse event to protocol procedure or study drug.  The 
assessment of the relationship of an adverse event to the administration of the 
study drug is a clinical decision based on all available information at the time 
of the completion of the eCRF. 
 
Intensity/Severity of an Adverse Event 
 
In addition to assessing the relationship of the administration of the study drug 
to adverse events, an assessment is required, in order to determine the 
intensity (severity) of the event.  
 
The following classifications should be used: 
 

BIOCARD Protocol 20Jan2017 Amendment 1  
 
 
Confidential 
 
Page 23 of 30 
 
Mild:   
A mild adverse event is an adverse event, usually transient in nature and 
generally not interfering with normal activities. 
 
Moderate:   
A moderate adverse event is an adverse event that is sufficiently 
discomforting to interfere with normal activities. 
 
Severe:   
A severe adverse event is an adverse event that incapacitates the subject and 
prevents normal activities.   Note that a severe event is not necessarily a 
serious event; nor must a serious event necessarily be severe. 
 
7.7.3 Adverse Event Documentation 
All adverse events must be fully recorded on the adverse event eCRFs.  
Documentation must be supported by an entry in the subject file.  Laboratory 
tests, vital signs and ECG abnormalities considered by the Investigator to be 
clinically relevant should be reported on the adverse event eCRFs.  Signs and 
symptoms of each AE should be described in detail (e.g., start and stop dates, 
severity/intensity, relationship to study drug, action taken, and event 
resolution). 
 
Adverse events and laboratory test abnormalities fulfilling the definition of a 
serious adverse event should, in addition, be reported on the Serious Adverse 
Event Reporting Form. 
 
7.7.4 Reporting of Serious Adverse Events  
Study site personnel must alert Eli Lilly, or its designee, of any SAE within 24 
hours of their awareness of the event via a sponsor-approved method.  Alerts 
issued via telephone are to be immediately followed with official notification 
on study-specific SAE forms.  
 
Serious adverse events occurring after a subject receives a dose of study drug 
will be collected until 48 hours after the  dosing of the study drug, regardless 
of the investigator’s opinion of causation.  Therefore, SAEs that occur later 
than 48 hours after the dosing of the study drug are not required to be reported 
unless the investigator feels the events were related to either study drug or a 
protocol procedure. 
 
If a patient experiences a SAE after signing informed consent, but prior to 
receiving study drug, the event will NOT be reported unless the investigator 
feels the event may have been caused by a protocol procedure.  Previously 
planned (prior to signing the ICF) surgeries should not be reported as SAEs 
unless the underlying medical condition has worsened during the course of the 
study.

8. STATISTICAL ANALYSIS 
 
 
  
8.1 General Statistical Considerations 
 
All statistical analyses will be performed using SAS® version 8.2 or higher. 
 
The study data collected under the BIOCARD protocol, such as but not limited to 
subjects’ demographic and baseline characteristics, medical history, neurological 
and behavioral evaluations, neuropsychological test results, MRI, and other 
biomarker studies will be transferred to Avid for analysis purposes. 
 
Additional details concerning statistical analyses will be included in the Statistical 
Analysis Plan (SAP) to be completed per Avid SOP. 
 
 
  
8.2 Safety Analysis 
 
Adverse events including injection site reactions will be summarized in terms of 
number and percentage of subjects experiencing an AE. The summary will be 
further broken down by system organ class (SOC) and preferred term using 
Medical Dictionary for Regulatory Activities (MedDRA) terms. Adverse events 
will also be presented by severity, relationship to treatment and seriousness. All 
subjects who experience SAEs, or who discontinue due to AEs, will be 
summarized. 
 
Discontinuation  
 
All subjects who discontinued participation prior to completing the study will be 
listed and their discontinuation reasons will be tabulated. 
 
 
  
8.3 Image Analysis 
All flortaucipir (18F) PET images obtained starting at 75 minutes post injection 
will be analyzed. Additional details concerning image analyses will be included in 
a separate document to be completed prior to the end of the study.  
8.4 Exploratory Analyses 
Exploratory analyses will examine the relationship among flortaucipir (18F) 
uptake measurements, cognitive and neuropsychiatric measurements, and other 
collected biomarkers in subjects, and will explore whether the flortaucipir (18F) 
uptake measurements are correlated with other biomarkers, cognitive status, and 
clinical presentation. Additional retrospective analyses will be conducted to 
explore the possible risk factors of tau deposition.

9. USE OF DATA AND PUBLICATION
Avid adheres to the Pharmaceutical Research and Manufacturers of America 
(PhRMA) Principles on Conduct of Clinical Trials and Communication of Clinical 
Trial Results. A complete copy of these principles is available from Avid and can 
also be found at the PhRMA website (http://www.phrma.org). Avid’s policy is briefly 
summarized below: 

We commit to timely communication of meaningful results of controlled clinical
trials, regardless of outcome.

As a sponsor, we may recommend that the Investigator(s) delay or decline
publication in cases where the study design, conduct, or data are insufficient to
allow meaningful interpretation. Avid and the Investigator(s) will discuss the
study design and data in advance of the study, and again after completion, and
will strive, through appropriate scientific debate, to reach a consensus regarding
the potential merits of publication.

Avid retains the right to review any manuscripts, presentations, or abstracts before
they are submitted for publication. Where differences of opinion or interpretation
exist regarding data planned for publication, the parties (Avid and the
Investigator) should try to resolve them through appropriate scientific debate.
Avid retains the right to delay publication for up to 60 days to protect intellectual
property.

Anyone who provides substantial contributions should receive appropriate
recognition as an author or contributor when the manuscript is published.
10. INVESTIGATOR’S REGULATORY OBLIGATIONS
All clinical work conducted under this protocol is subject to Good Clinical Practice 
regulations; this may include an inspection by Avid and/or Health Authority 
representatives (FDA or international regulatory authorities) at any time. 
10.1 Institutional Review Board (IRB) 
The intent of the research program, the trial protocol, the patient 
information/informed consent form and any advertising material used to recruit 
subjects must be submitted to the clinical investigator’s local IRB and its approval 
must be obtained prior to its use. A copy of the approval must be forwarded to 
Avid. When necessary, an extension or renewal of IRB approval must be obtained 
and also forwarded to Avid. 
10.2 Informed Consent 
A signed, written informed consent must be obtained from each patient.  A copy 
of the signed informed consent should be given to the patient for their records.  A 
copy of the local IRB’s approved version of the informed consent form must be 
forwarded to Avid, or its designee, for review prior to being used to obtain patient 
consent. 

BIOCARD Protocol 20Jan2017 Amendment 1  
 
 
Confidential 
 
Page 26 of 30 
 
 
 
  
10.3 Protocol Adherence 
 
 
The protocol must be read thoroughly and the instructions must be followed 
exactly. Where a deviation occurs, it must be documented, the sponsor/monitor 
informed, and a course of action agreed upon. 
 
 
  
10.4 Documents Necessary for Initiation of the Trial 
Avid must be provided with the following documents prior to the enrollment of 
any subjects: 
• 
Original signed and dated Statement of Agreement page; 
• 
Copy of the IRB and radiation safety committee approval (if applicable); 
• 
Copy of the IRB stamped approved consent form; 
• 
Name and location of the laboratory utilized for laboratory assays, and 
other facilities conducting tests, including laboratory certification number 
and date of certification if available;  
• 
List of reference range laboratory values; and 
• 
Any additional licenses required in order to order to use flortaucipir (18F). 
 
 
  
10.5 Study Drug Control 
The receipt of clinical supplies (e.g. starting material for flortaucipir (18F)) must 
be documented at the site.   
 
All drug supplies for this trial should be retained in a safe and secure place at all 
times during the trial. Flortaucipir (18F) should be prepared by a qualified PET 
manufacturing site and administered by a qualified individual under the 
investigator’s supervision. An up-to-date drug inventory/dispensing record must 
be maintained and all drug supplies must be justified. After completion of the 
trial, all remaining clinical supplies must be returned to the sponsor, or their 
representative.   
 
 
  
10.6 Data Collection 
 
Electronic case report forms (eCRFs) will be used for this trial.  Individual patient 
files should include appropriate source documents, including but not limited to 
patient’s medical records and laboratory test results. The files should include 
information such as visit dates, records of medical history, examinations 
administered, laboratory, concomitant treatment, any adverse event encountered 
and other notes as appropriate. These constitute “source data”. All entries on the 
eCRFs must be backed up by source data. Original electronic versions of imaging 
studies are also considered source data and should be kept on file by the 
site/imaging center, and appropriate copies should be forwarded to Avid as 
specified in the imaging manual.   
 

BIOCARD Protocol 20Jan2017 Amendment 1  
 
 
Confidential 
 
Page 27 of 30 
 
Each patient’s source file should include an original signed informed consent 
form. When the trial is completed, the informed consent form should be kept on 
file with other trial related records. 
 
All original laboratory reports must be available for review in each patient’s file.  
It is important that the original reports be available for review because of the 
possibility of inaccuracies or errors in transcribing data from original records to 
the eCRF. 
 
The eCRFs must be kept in order and up-to-date so that they always reflect the 
latest observations on the subjects that are enrolled in the trial. The eCRFs must 
be completed for each patient enrolled in the trial and signed by the investigator. 
This should be done as soon as possible after completion of the patient’s 
participation in the trial. A monitor will verify the source data for all information 
on the eCRF. 
 
 
  
10.7 Adverse Events 
 
All adverse events encountered during the clinical trial must be documented on 
the eCRF, whether or not considered drug-related. 
 
Eli Lilly must be notified immediately (as soon as possible, and in all cases within 
24 hours) of a drug experience, condition, development, or event, which is 
considered serious. Eli Lilly must be notified immediately of any findings with 
the use of the drug that may suggest significant hazards, contraindications, 
adverse drug reactions (ADRs) and precautions pertinent to the safety of the drug.  
The investigator will be requested to complete a separate report form in addition 
to the information on the eCRF. See section 7.7.4 for reporting serious adverse 
events 
 
If a SAE is determined to be unexpected (not previously reported or described by 
Avid), and study drug-related, Eli Lilly will notify the investigator in writing.  
The investigator should forward this notification to the IRB within 24 hours of 
receipt. 
 
 
  
10.8 Records Retention 
 
All correspondence (e.g., with Avid, IRB, etc.) relating to this clinical trial should 
be kept in appropriate file folders.  Records of subjects, source documents, and 
drug inventory sheets pertaining to the trial must be kept on file. Records must be 
retained until the date a marketing application (NDA) is approved for the drug for 
the indication for which it is being investigated, or until 2 years following the date 
of clinical trial termination or completion, whichever is later. If no application is 
to be filed, or if the application is not approved for such indication, records should 
be kept until 2 years following the date of clinical trial termination or completion.

Page 28 of 30 
 
If an investigator moves, withdraws from an investigation, or retires, the 
responsibility for maintaining the records may be transferred to another person 
who will accept the responsibility. Notice of transfer must be made to and agreed 
upon by Avid.

11.2 Trial Flow Chart 
 
a. 
Screening may take place over several days.  All assessments must be performed within 90 days prior to the flortaucipir (18F) imaging session. Subjects may be permitted to return for the 
flortaucipir (18F) PET scan after the 90 day window with sponsor approval if the investigator does not recognize any significant medical changes. 
b. 
A follow-up phone call to the subject, or information where applicable, will be conducted within 2 or 3 business days of each imaging day, but not before 48 hours post-injection, to confirm subject 
well-being and to collect information about any new adverse events.  If both of these days are not business days, the follow-up phone call can occur the following business day. 
c. 
ECG (with results reviewed prior to flortaucipir (18F) administration). 
d. 
Subjects will receive a single IV bolus injection target dose of 370 MBq (10 mCi) of flortaucipir (18F) injection followed by a saline flush.  
e. 
At approximately 75 minutes following flortaucipir (18F) injection, a continuous 30-minute brain scan will begin. 
f. 
Or a licensed/credentialed medical professional (i.e. PET technologist, imaging center nurse or a regional equivalent) designated by the site principal investigator. If a designee performs this 
activity, the physician must be available to provide medical consultation.  
g. 
Or physician designee. 
h. 
Serum pregnancy test 
i. 
Urine pregnancy test prior to flortaucipir (18F) injection
