BACKGROUND 
 
Alzheimer disease (AD), the most common cause of dementia, is a neurodegenerative 
disorder with the pathological abnormality of beta-amyloid (Aβ) plaques. One promising 
treatment for AD aims at clearing Aβ plaques through immunotherapy. Patients with amnestic 
mild cognitive impairment (a-MCI) are a group recognized at being at high risk of progressing to 
Alzheimer disease. Treatment of a-MCI with immunotherapy with intravenous immunoglobulins 
(IVIG) could potentially reduce the risk of progression to Alzheimer disease. 
Evidence for immunotherapy as a therapy for AD had its beginnings in 1996 when 
Solomon and colleagues demonstrated in vitro that Aβ monoclonal antibodies disassembled Aβ 
fibrils. This potential strategy of immunotherapy for AD was further supported by Schenk, et al. 
[1] who found that Aβ vaccination of mice diminished Aβ plaques. 
Immunotherapy research eventually progressed to a phase II trial of active immunization 
against Aβ-42 in 2001 and initially showed promising results. The group of subjects who 
successfully developed Aβ antibodies showed not only a significantly slower rate of cognitive 
decline over one year compared to the placebo group, but also improvement in memory scores 
which positively correlated with antibody titer [2]. A later neuropathological examination of three 
AD patients who were actively immunized against Aβ (deaths were not attributed to the 
immunization) revealed remarkable clearance of cortical Aβ [3]. Unfortunately, 6% of the 298 
participants who were immunized developed an aseptic meningoencephalitis and the trial was 
discontinued [4]. 
A leading theory regarding the etiology of this postvaccination meningoencephalitis is T- 
cell mediated inflammation triggered by the Aβ-42 molecule used for active immunization [4]. 
One strategy to avoid this adverse inflammation is to administer the Aβ antibodies passively 
such as via IVIG. 
Commercial IVIG has been shown to contain antibodies to Aβ [5] [6]. The molecular 
mechanism of Aβ clearance by IVIG was studied in vitro by Istrin and colleagues [6] who found 
that the antibodies in IVIG disassembled the fibril plaques by enhancing microglial migration 
thus leading to the phagocytosis of Aβ. 
In an open-label study, Dodel and colleagues [7] found that AD patients treated with 
IVIG (Octagam® 0.4 g/kg daily x 3 days every 4 weeks for 6 months) demonstrated a mean 
cognitive improvement of 3.7 points on the ADAS-cog after 6 months of treatment. Dodel et al. 
[7] also found that Aβ levels in the CSF decreased by 30% whereas serum Aβ levels increased, 
thus supporting amyloid clearance theories. There were no serious adverse events associated 
with IVIG in this study. 
Relkin et al. [8] completed an 18-month open-label study of IVIG (Gammagard) for mild 
AD where subjects were randomized to four consecutive dosing periods: 1) 0.4 g/kg every 2 
weeks, 2) 0.4 g/kg/week, 3) 1 g/kg every 2 weeks, and 4) 2 g/kg every 4 weeks for 6 months 
followed by a 3-month washout. All patients were then treated with 1g/kg every 2 weeks starting 
in months 10 through 12, then 0.4 g/kg every 2 weeks starting in months 13-18. The results 
showed a dose-dependent increase in serum Aβ suggesting amyloid clearance. A mean 
improvement of 2.5 points on the MMSE after 6 months (and mean improvement of 0.5 points at 
18 months) was observed; this is contrasted to the expected 1.5 point decline per 6 months with 
AD. Higher doses of IVIG did not lead to higher cognitive scores and, in fact, the group treated

Version: 6.8.16 
 
 
 
 
with the lowest dose of 0.4 g/kg per week maintained the highest MMSE scores. There were no 
serious adverse events during this study. 
In a Phase II trial of IVIG (Gammagard 10%) in mild to moderate Alzheimer disease, 
Relkin et al [9] studied IVIG at doses ranging from 0.2 to 0.8 g/kg every two to four weeks over 
18 months. The study demonstrated significantly decreased cognitive decline on the ADAS-cog 
as well as significantly decreased brain atrophy in subjects receiving early IVIG compared to the 
delayed treatment arm (placebo for 6 months then IVIG). On MRI, the annual ventricular 
enlargement rate was 6.7% for those treated with IVIG compared to 12.3% for those previously 
taking placebo; the rate of atrophy was lowest with the IVIG dose of 0.4 g/kg every 2 weeks. 
There were no serious adverse events during this study. 
There are two ongoing phase III trials of IVIG 10% (Octagam and Gammagard) for mild 
to moderate AD. 
In July 2009, Fillit et al [10] published a retrospective analysis of the risk of AD and 
related disorders in people ≥ 65 with a prior history of one or more IVIG treatments for 
indications other than AD. Cases were matched to controls on age, gender, and risk factors for 
AD and related disorders. This study analyzed an approximate 4-year period and demonstrated 
that previous treatment with IVIG was associated with a 42% lower risk of developing AD and 
related disorders. 
The potential protective effect of IVIG against AD could best be utilized in persons 
identified to be at greatest risk for developing AD prior to the development of advanced disease 
and neuropathology. Persons with a-MCI have been identified a group at high risk of 
progressing to AD with a conversion rate of approximately 15% per year. [11, 12] Vermuri used 
data from the Alzheimer Disease Neuroimaging Initiative including CDR-SB and MMSE to 
assess disease progression (while investigating potential biomarkers, MRI and CSF) of AD and 
demonstrated that 60 of the 192 subjects with a-MCI converted to AD over 1.5 years; i.e., 
annual conversion rate from a-MCI to AD of 20.8% [13]. 
This study will investigate treating persons with a-MCI with IVIG (NewGam 10%) 0.4g/kg 
every 14 days over the course of three months with the intent of showing differences in brain 
MRI volume, cognition, and conversion to AD when compared with placebo after 24 months. We 
chose this dose of IVIG based on recent evidence from Relkin [8] who showed that this may be 
an optimal IVIG dose for reduction of brain atrophy in patients with AD. Furthermore, Fillet [10] 
demonstrated a lower risk of AD in patients who had received only one treatment of IVIG.

STUDY DRUG AND TREATMENT 
 
6.1 
Description of study drug 
NewGam, the current working title for a new IVIG formulation, is a newly developed 10% 
human normal immunoglobulin solution ready for intravenous administration. Adverse Drug 
Reactions (ADRs) reported for NewGam are expected to be similar in type and intensity to  
those reported with other IVIG preparations. 
The NewGam manufacturing process achieves a significant viral reduction through a 
combination of two dedicated manufacturing process steps: solvent/detergent (S/D) treatment 
and nanofiltration (20 nm). Based on the combination of these two steps, NewGam complies 
with the latest international consensus on best practices for viral safety. The Source Q 
chromatography (ion-exchange chromatography) step in the NewGam process also contributes 
significantly to the viral safety of NewGam. The efficacy of the virus inactivation procedures has 
been extensively validated according to relevant international guidelines in place. Further 
information can be found in the current Investigator’s Brochure. 
6.2 
Shipping, handling, and storage 
IVIG will be shipped directly to the pharmacy or investigational site, after all required 
regulatory and legal documents have been received by the Sponsor. 
Upon receipt of the study drug shipments, the unblinded pharmacist will verify the 
condition of the study drug and perform study drug accountability. Acknowledgement of receipt 
will be documented in the Pharmacy Binder. A temperature logger showing the transport 
temperature will be read out by the shipper and release the drug if the transport temperature is 
verified to be between +2°C to + 8°C (36°F to 46°F). If there was a deviation from this 
temperature range, an Octapharma Project Manager or Qualified Person must assess the 
temperature log and approve release. 
The study drug will be stored in a secure area with access restricted only to authorized 
personnel. NewGam may be stored for 15 months at +2°C to + 8°C (36°F to 46°F) from the date 
of manufacture. 
6.3 
Special precautions for storage 
• 
Do not freeze. Frozen product should not be used 
• 
Do not use after expiration date 
• 
Other than the unblinded pharmacist, all other site personnel are fully blinded and may 
not handle, store or dispense study drug 
6.4 
Drug accountability 
The investigator is responsible to ensure supervision of accurate monitoring of the 
receipt, storage and allocation of the study drug. Copies of all invoices of study drug shipments 
must be retained. Accurate study drug inventory, dispensing and accountability logs must be 
obtained and stored in the Pharmacy Binder.

6.5 
Blinding and unblinding 
 
The study coordinator, investigator, and infusion nurse will be blinded to whether the 
subject is receiving placebo or NewGam. The pharmacist will receive the assignment from the 
research scientist who will develop the randomization scheme. Both will know of the subject’s 
treatment assignment. While participating in the study, a subject’s treatment assignment should 
only be unblinded when knowledge of the treatment is essential for the further medical 
management of the subject. Unblinding for any other reason during the study will be considered a 
protocol violation. 
 
Subjects participating in the extension portion of the study may be unblinded upon study 
completion (Visit 15/month 60). Subjects declining participation in the extension portion of the 
study or subjects not completing the study will be unblinded upon request. 
 
6.6 
Study drug dosage 
The dose level of IVIG at 0.4 g/kg or 0.9% saline placebo will be administered by IV 
infusion once every 14 days for two months. There is no provision for dose adjustments by the 
investigator under this protocol. 
6.7 
Study drug preparation and infusion 
• 
The unblinded pharmacist will prepare the IVIG or placebo for each infusion. 
• 
The IVIG should be inspected visually for particulate matter and discoloration prior to 
administration, whenever solution and container permit. Do not use if turbid and/or 
discoloration is observed. 
• 
The IVIG must not be mixed with other medicinal products or administered 
simultaneously with other intravenous preparation in the same infusion set. Do not mix 
with IVIG products from other manufacturers. 
• 
Do not freeze. Solutions that have been frozen should not be used. 
• 
IVIG bottle is for single use only. NewGam contains no preservative. Any bottle that has 
been entered should be used promptly. Partially used bottles should be discarded. 
• 
Content of IVIG bottles may be pooled under aseptic conditions into sterile infusion bags 
and infused within 8 hours after pooling (within 72 hours if stored at 2-8°C [36-46°F]). 
• 
Do not use after expiration date. 
• 
IVIG should not be diluted. 
• 
IVIG must be allowed to warm to room or body temperature prior to infusion if stored at 
2-8°C (36-46°F). 
• 
0.4 g/kg body weight of Newgam 10% or 0.9% saline placebo is transferred into an EVA 
infusion bag. 
• 
The infusion bag must be covered with a dark hood and dark infusion lines attached 
prior to infusion to maintain the study blind. 
6.8 
Incompatibilities 
• 
NewGam must not be mixed with other medicinal products or administered 
simultaneously with other intravenous preparations in the same infusion set.

6.9 
Administration 
• 
IVIG should be inspected visually for particulate matter and discoloration prior to 
administration, whenever solution and container permit. Do not use if turbid and/or 
discoloration is observe 
• 
IVIG should be at room or body temperature during administration. Only administer 
intravenously. 
• 
Any bottle that has been opened should be used promptly. Partially used bottles should 
be discarded. 
• 
NewGam is not supplied with an infusion set. If an in-line filter is used the pore size 
should be 0.2 – 200 microns. 
• 
Do not use a needle of larger than 16 gauge to prevent the possibility of coring. Insert 
needle only once, within the stopper area delineated (by the raised ring for penetration). 
The stopper should be penetrated perpendicular to the plane of the stopper within the 
ring. 
6.10 Rate of administration 
The initial infusion rate of IVIG (NewGam) or placebo will be 0.01 mL/kg/min (60 
mg/kg/hr) for the first 30 minutes; if tolerated, advanced to 0.02 mL/kg/min (120 mg/kg/hr) for 
the second 30 minutes; if tolerated, advanced to 0.03 mL/kg/min (180 mg/kg/hr) for the second 
30 minutes and, if tolerated, advanced to 0.04 mL/kg/min (240 mg/kg/hr) for the remaining time 
at the discretion of the treating Investigator. 
If adverse events (AEs) occur during infusion, the rate should be reduced to half the rate 
at which the event occurred, or the infusion interrupted until symptoms subside. The infusion 
may then be resumed at a rate tolerated by the patient. 
The batch number(s) and number of different vial sizes used will be recorded on the 
drug accountability form. 
6.11 Concomitant therapy 
6.11.1 Prohibited 
During the course of the study, experimental medications for MCI or AD and all other 
experimental medications are prohibited. Subject must refrain from using any medication, 
vitamin, or herbal supplement considered to enhance cognition or indicated for a-MCI or AD 
unless approved by the investigator. Prohibited medications, vitamins and herbal supplement 
included but are not limited to cholinesterase inhibitors, memantine, Axona, ginko biloba, and 
huperzine. 
6.11.1 Permitted 
Concomitant medications will be assessed at all study visits. Concomitant medications 
are prescribed or over-the-counter medications and should be consistent with the 
inclusion/exclusion criteria. Concomitant medication appropriate to the subject’s condition may 
be prescribed during the course of the study with the exception of those listed above. 
Routine vaccinations (i.e., flu vaccination) with commercially available therapeutics are 
permitted but must not be given within four weeks before or after the administration of the study 
drug. No vaccination for a-MCI or AD is allowed during the course of the study.

EVALUATIONS BY VISIT 
 
The overall summary of study activities by visit is provided in Appendix C at the end of 
the document. 
 
Screening procedures at visit 1 will take place up to 28 days prior to Visit 2 (Day 1) 
dosing. Screening labs and assessments will be performed during the screening period. A brain 
MRI will be obtained as standard of care within 6 months prior to the screening period. The first 
dose of study drug is administered on Day 1. Visits 2 through 6 have a ±1 day window and 
occur every 14 days over two months. The investigator will determine if a subject is suitable to 
continue following the missed infusion. Visits 7 through 12 (Month 4 through Month 24) have a 
±7 day window.  Visits 13 through 15 (Month 36 through Month 60) have a ±14 day window). 
 
All study screening data from Visit 1 including laboratory results must be reviewed for 
study eligibility prior to receiving first dose of study drug. Visit 2 physical exams and neurological 
exams prior to infusion may occur within 72 hours prior to the first infusion. Prior to infusion, a 
review of concomitant medications and AEs takes place to ensure that no excluded medications 
have been added or medication discontinued or dose changed that were required to have been 
stable. If the subject continues to be eligible for enrollment, the subject will be randomized, 
infused with study medication and will remain in the infusion clinic for at least 4 hours following  
the start of the infusion for safety assessments on Visit 2 (Day 1).

• 
Is in significant violation of the protocol 
• 
Experiences an intolerable AE or SAE 
• 
Is non-compliant 
• 
Withdrawal of consent 
• 
Lost to follow up 
•

Replacement of subjects 
Subjects screened but not randomized will be replaced. Subjects withdrawn after 
receiving the third infusion will not be replaced but will be followed if they provide consent. 
 
10.0 
ADVERSE EVENTS 
 
10.1 Adverse event definition 
An AE is any untoward event that occurs any time after randomization to the double 
blind treatment until the end of study (visit 12, visit 15, or ET visit). The event need not have a 
causal relationship with the study drug or treatment. Adverse events include, but are not limited 
to clinically significant changes in clinical status, physical or neurological examinations, ECG, 
abnormal laboratory findings, exacerbations of underlying disease, and drug interactions, 

Sutter Institute for Medical Research 
Protocol 
PI: Shawn Kile MD 
Page 20 
Version: 6.8.16 
 
 
dependency, misuse and abuse. All AEs must be documented on the Adverse Event page of 
the CRF and in the subject’s medical notes. Each AE is evaluated for duration, severity, 
seriousness, relatedness to study drug, and action taken. The investigator may be asked to 
provide follow-up information. 
10.2 Serious adverse event (SAE) definition 
A serious adverse event is one that at any dose (including overdose): 
• 
Results in death 
• 
Is life-threatening1 
• 
Requires inpatient hospitalization or prolongation of existing hospitalization 
• 
Results in persistent or significant disability or incapacity2 
• 
Is a congenital anomaly/birth defect 
• 
Is a medically important condition: 
Suspected transmission of an infectious agent, 
Thromboembolic events, 
Cerebral hemorrhage resulting in clinical disability, or 
Other reactions that should be reported in an expedited manner although they 
did not immediately result in one of the above seriousness criteria 
10.3 Other relevant drug safety information: 
Any safety information relating to 
• 
Pregnancies/breastfeeding, 
• 
Drug abuse (persistent, sporadic or intentional excessive use of a medicinal product 
inconsistent with the SPC or acceptable medical practice), 
• 
Overdose (treatment exceeding the medically recommended dose), 
• 
Medication errors (prescribing or dispensing error), 
• 
Interactions with other medicinal products or devices 
• 
Associated with NewGam 10%, even if no adverse drug reaction occurred. 
 
 
1“Life-threatening” means that the subject was at immediate risk of death at the time of the serious adverse event; it does 
not refer to a serious adverse event that hypothetically might have caused death if it were more severe. 
2“Persistent or significant disability or incapacity” means that there is a substantial disruption of a person’s ability to carry 
out normal life functions.

Version: 6.8.16 
 
 
 
10.4 Adverse events severity 
Severity of AEs will be assessed using the National Cancer Institute (NCI) Common 
Terminology Criteria for Adverse Events (CTCAE) Version 3.0 for toxicity and adverse event 
reporting. A copy of the CTCAE Version 3.0 can be downloaded from the CTEP homepage 
(http://ctep.info.nih.gov). AEs not corresponding to the CTCAE term will be assessed 
according to their impact on the subject’s ability to perform daily activities as follows: 
• 
Mild (grade 1) – the AE does not interfere in a significant manner with the 
subject’s normal functioning level. It may be an annoyance. 
• 
Moderate (grade 2) – the AE produces some impairment of functioning, but is 
not hazardous to health. It is uncomfortable or an embarrassment. 
• 
Severe (grade 3) – the AE produces significant impairment of functioning or 
incapacitation and is a definite hazard to the subject’s health. 
• 
Life Threatening (grade 4) – Life threatening or disabling. 
• 
Fatal (grade 5) Causes death of the participant. 
The investigator must appraise all abnormal laboratory results for their clinical 
significance. If any abnormal laboratory result is considered clinically significant, the investigator 
must provide details about the action taken with respect to the test drug and about the patient’s 
outcome. 
10.5 Adverse event reporting 
All AEs, whether observed by the investigator or reported by the patient, must be 
recorded, with details about the duration and intensity of each episode, the action taken with 
respect to the test drug, and the patient’s outcome. The investigator must evaluate each 
adverse experience for its relationship to the test drug and for its seriousness. The initial report 
must be as complete as possible, including details of the current illness and (serious) adverse 
event, and an assessment of the causal relationship between the event and the investigational 
product(s). Information not available at the time of the initial report (e.g., an end date for the 
adverse event or laboratory values received after the report) must be documented on a follow- 
up form. A final report to document resolution of the adverse event is required. 
10.6 Investigator reporting to the FDA 
Adverse drug reactions that are serious, unlisted/unexpected, and at least possibly 
associated to the drug, and that have not previously been reported in the Investigators 
brochure, or reference safety information document should be reported promptly to the FDA in 
writing by each investigator/physician engaged in clinical research. A clear description of the 
suspected reaction should be provided along with an assessment as to whether the event is 
drug or disease related. 
The investigator/physician shall notify the FDA by telephone or by fax of any unexpected 
fatal or life threatening experience associated with the use of the drug as soon as possible, but 
no later than 7 calendar days after the sponsors initial receipt of the information. Each phone 
call or fax shall be transmitted to the FDA new drug review division in the Center for Drug 
Evaluation and Research or the product review division in the Center for Biologics Evaluation 
and Research that has responsibility for review of the IND if applicable. 
10.7 Reporting of adverse drug reactions and other safety information to study 
supporter 
All suspected AEs and other safety information associated with the administration of 
NewGam have to be reported to:

2.0 
12.0 RESPONSE CRITERIA 
 
The MMSE, CDR-SB, and ADAS-cog are scheduled to occur at 4, 8, 12, 16, 20, 24, 36, 
48, and 60 months after Visit 1. 
 
3.0 
13.0 PROTOCOL DEVIATIONS 
 
When an emergency occurs that requires a deviation from the protocol for a subject, a 
deviation will be made only for that subject. A decision will be made as soon as possible to 
determine whether or not the subject (for whom the deviation from protocol was effected) is to 
continue in the study. The subject’s medical records will completely describe the deviation from 
the protocol and state the reasons for such deviation. In addition, the Investigator will notify the 
SHCIRC in writing of such deviation from protocol. 
Non-emergency minor deviations from the protocol will be permitted with approval of the 
principal investigator. 
 
14.0 
DATA RECORDING, RETENTION, AND MONITORING 
 
14.1 Data entry and maintenance 
Investigator responsibilities are set out in the ICH guideline for Good Clinical Practice 
(GCP) and in the US Code of Federal Regulations. 
Study personnel will construct case report forms (CRFs), record all study data onto the 
CRFs and enter the data into a 21 CFR Part 11 compliant database. 
14.2 Study records retention 
The investigator must ensure that the records and documents pertaining to the conduct 
of the study and the distribution of the study drug, that is copies of CRFs and source documents 
(original documents, data, and records [e.g., hospital records; clinical and office charts; 
laboratory notes; memoranda; subject’s diaries or evaluation checklists; SAE reports, pharmacy 
dispensing records; recorded data from automated instruments; copies or transcriptions certified 
after verification as being accurate copies; microfiches; photographic negatives, microfilm, or 
magnetic media; x-rays; subject files; and records kept at the pharmacy, at the laboratories, and 
at medico-technical departments involved in the clinical study; documents regarding subject 
treatment and study drug accountability; original signed informed consents, etc.]) be retained by 
the investigator for as long as needed to comply with national and international regulations 
(generally 2 years after discontinuing clinical development or after the last marketing approval). 
The investigator agrees to adhere to the document/records retention procedures by signing the 
protocol. 
14.3 Data monitoring committee 
The Data Monitoring Committee (DMC) will be composed of independent reviewers who 
will meet to review the efficacy and safety data and determine a risk/benefit analysis in this 
subject population. The purpose of the DMC is to advise on serious safety considerations, lack 
of efficacy, and any other considerations within the charge to the Committee. The DMC may 
request additional meetings or safety reports as deemed necessary upon discussion with the 
investigator or Octapharma and its representatives. The DMC may stop the study following 
review of results from the interim analysis.

STATISTICAL ANALYSIS 
 
15.1 Primary endpoint 
The aim of the primary efficacy analysis is to demonstrate an advantage for subjects 
treated with IVIG over subjects treated with placebo at the end of the study as measured by 
change in ventricular volume. The primary efficacy analyses will be performed on the intent-to- 
treat (ITT) population. The ITT population is defined as all subjects who were randomized, 
received three or more infusions, and had a brain MRI at baseline and at 24 months. 
Annualized percent change in total ventricular volume (APCV) is the primary biomarker 
of interest. Brain MRI will be obtained at baseline, 12 months, 24 months, 36 months, 48 
months, and 60 months. Differences between the IVIG and placebo group at month 12, 24, 36, 
48, and 60 will be analyzed using a 2 x 2 analysis of variance. Participants will also be classified 
as early MCI (EMCI) if baseline CDR-SB is less than 1.5, and late MCI (LMCI) if CDR-SB is 
greater than or equal to 1.5. 
Treatment (IVIG, placebo), MCI status (EMCI, LMCI), and the treatment X MCI status 
interaction will be included in the model. If the interaction is statistically significant (p< 0.05), 
MCI status will be stratified and differences in APCV between the groups compared within each 
stratum. 
15.2 Secondary Endpoints 
15.2.1 
Conversion to AD 
Conversion to AD is measured by NINCDS-ADRDA and NIA [14] criteria for diagnosis of 
Alzheimer Disease and Clinical Dementia Rating (CDR) (Appendix A). 
Kaplan-Meier survival curves will be estimated and will plot the proportion of treatment 
and control subjects who remain without a diagnosis of AD at month 24, 36, 48, and 60. The 
log-rank test will be used to determine whether the survival curves are different for the two 
groups of subjects. Cox proportional hazards will be used to assess the incidence of AD in 
treatment versus control subjects adjusting for age and sex. 
15.2.2 
Cognitive change 
The CDR-SB, MMSE, and ADAS-cog are administered at baseline and at months 4, 8, 
12, 16, 20, 24, 36, 48, and 60.  Separate linear mixed-effects modeling will be used to compare 
differences in the scores on each these tests using all available observations. Treatment 
(IVIG/placebo), MCI status (early, late), and treatment X MCI status will be fixed factors and the 
respective baseline score will be included as the continuous covariate. For statistically 
significant (p< 0.05), interactions, MCI status will be stratified and the analyses will be 
conducted for each stratum. 
Data will be analyzed to assess safety after 25 subjects complete three months of follow- 
up. Safety will be evaluated though documentation of adverse events. Appropriate safety data 
summaries will be provided to the DSMC after each interim analysis. 
15.2.3 
CSF Aβ1-42/CSF P-Tau181P Alzheimer signature 
Annualized percent change in ventricular volume between the IVIG and placebo group at 
month 12, 24, 36, 48, and 60 will be also analyzed specifically in subjects with positive CSF 
Aβ1-42/CSF P Tau181P Alzheimer signature.

16.0    SAMPLE SIZE AND POWER FOR PRIMARY ENDPOINT 
 
Twenty-five subjects will be randomized to placebo and 25 subjects will be randomized  
to the group receiving IVIG. Twenty-five subjects in each group provides 82% power to detect a 
120 unit difference in mean ventricular volume between the groups at month 26. This calculation 
is based on a two-sided test with alpha set at 0.05. 
 
17.0    IMPLICATIONS AND DIRECTION FOR FUTURE STUDIES 
 
This study is designed to assess the efficacy of the smallest reasonable dose of IVIG 
that could prevent ventricular atrophy in patients with a-MCI. Subjects will receive IVIG 0.4g/kg 
every 2 weeks as the half-life of IVIG antibodies has been reported as 9.3 days [8]; furthermore 
Relkin [8] found the dosing schedule of 0.4/kg every 2 weeks to be most effective in reducing 
brain atrophy. [9] We decided to study the smallest reasonable course of IVIG which would be 5 
total treatments as a 2g/kg total treatment dose is standard dose used for other indications of 
IVIG (including neurological disorders). IVIG has not been investigated in a-MCI and we 
hypothesis that patients with early Alzheimer’s pathology may require smaller doses of IVIG. 
Furthermore if effective, this short course would both reduce the risk of IVIG treatment adverse 
events and reduce cost of treatment. Both of the former would increase accessibility of this 
treatment to patients with a-MCI. At the end of the two years we plan to perform an add-on 
study with participating subjects to include an additional three years of follow-up (five years 
total). 
If the results of this exploratory study are found at the end of two years to show a trend 
towards positive efficacy with this treatment strategy, the current study may be expanded to 
include more subjects with dose-ranging investigations or the results used to design a large, 
multi-arm randomized trial. 
 
18.0 
ETHICAL AND LEGAL ISSUES 
 
The study will be submitted to the SHCIRC. A data safety monitoring committee will be 
convened to provide oversight of subjects’ safety before commencement of the study. 
18.1 Institutional review board approval 
The protocol for this study has been designed in accordance with the general ethical 
principles outlined in the Declaration of Helsinki. The review of this protocol by the SHCIRC and 
the performance of all aspects of the study, including the methods used for obtaining informed 
consent, must also be in accordance with principles enunciated in the declaration, as well as 
ICH Guidelines, Title 21 of the Code of Federal Regulations (CFR), Part 50 Protection of Human 
Subjects and Part 56 Institutional Review Boards. 
The investigator will be responsible for preparing documents for submission to the 
SHCIRC and obtaining written approval for this study. The approval will be obtained prior to the 
initiation of the study. 
The approval for both the protocol and informed consent must specify the date of 
approval, protocol number and version, or amendment number. 
Any amendments to the protocol after receipt of SHCIRC approval must be submitted by 
the Investigator to the SHCIRC for approval. The Investigator is also responsible for notifying  
the SHCIRC of any serious deviations from the protocol, or anything else that may involve 
added risk to subjects.

Any advertisements used to recruit subjects for the study must be reviewed and  
approved by the SHCIRC prior to use. 
18.2 Informed consent 
The investigator must obtain informed consent of a subject or his/her designee prior to 
any study related procedures as per GCPs as set forth in the CFR and ICH guidelines. 
Documentation that informed consent occurred prior to the subject’s entry into the study 
and the informed consent process should be recorded in the subject’s source documents. The 
original consent form signed and dated by the subject and by the person consenting the subject 
prior to the subject’s entry into the study, must be maintained in the investigator’s study files. 
18.3 Subject confidentiality 
Octapharma affirms the subject’s right to protection against invasion of privacy. In 
compliance with United States federal regulations, Octapharma requires the investigator to 
permit Octapharma representatives and, when necessary, representatives of the FDA or other 
regulatory authorities to review and/or copy any medical records relevant to the study in 
accordance with local laws. 
Should direct access to medical records require a waiver or authorization separate from 
the subject’s statement of informed consent, it is the responsibility of the Investigator to obtain 
such permission in writing from the appropriate individual. 
18.4 Protocol amendments 
Any amendment to this protocol must be agreed to by the principal investigator and 
reviewed by Octapharma. Amendments should only be submitted to the SHCIRC after 
consideration of Octapharma review. Written verification of SHCIRC approval will be obtained 
before any amendment is implemented. 
18.5 Premature discontinuation of study 
The responsible local clinical investigator and Octapharma have the right to discontinue 
this study at any time for reasonable medical or administrative reasons. Possible reasons for 
termination of the study could be but are not limited to: 
• 
Unsatisfactory enrollment with respect to quantity or quality. 
• 
Inaccurate or incomplete data collection. 
• 
Falsification of records. 
• 
Failure to adhere to the study protocol. 
• 
Statistical analysis demonstrates overwhelming efficacy of treatment. 
Any possible premature discontinuation would be documented adequately with reasons 
being stated, and information would have to be issued according to local requirements (e.g., 
SHCIRC/EC, regulatory authorities, etc.).

Observation 
20.1.2 
Other clinical features consistent with the diagnosis of probable Alzheimer 
disease, after exclusion of causes of dementia other than Alzheimer disease: 
• 
Plateaus in the progression of the illness 
• 
Associated symptoms of depression, insomnia, incontinence, delusions, illusions, 
hallucinations; catastrophic verbal, emotional, or physical outbursts, sexual disorders, 
and weight loss

AMENDMENT 1: FEBRUARY, 2011 
 
25.1 AMENDMENT 1: INTRODUCTION 
The mains reason for protocol amendment 1 are to revise exclusion criteria 23, Appendix E 
Brain MRI Instructions and administrative changes. 
 
 
25.2 AMENDMENT 1: SUMMARY OF CHANGES 
Section 4.2 Exclusion Criteria – Exclusion 23 
Changed from: 
23.  Concurrent or prior treatment with cholinesterase inhibitors and/or memantine, or Axona for 
cognitive enhancement. Exceptions (e.g. brief exposure to one of these medications) may be 
authorized if agreed upon by PI and sub-I) 
 
 
Changed to: 
23.  Concurrent treatment with cholinesterase inhibitors, memantine, Axona, or other 
prescription cognitive enhancing agents, or discontinuation of any of these agents within 90 
days prior to screening. 
 
 
Rationale: Exclusion 23 was originally included because it may clinicians have proposed 
cholinesterase inhibitors and memantine may improve cognitive function in patients with MCI. 
We did not want this to confound the results of the study. A study published in the Archives of 
Neurology in January, 2011 found that cholinesterase inhibitors or memantine were not 
associated with clinical improvement and may alternatively be associated with a decline in 
patients with MCI. This information, coupled with the fact the so many practitioners have started 
patients with MCI on these medications which makes recruitment of medication-naive patients 
difficult, led us to amend this exclusion. Therefore, we are allowing enrollment of patients

AMENDMENT 6: SUMMARY OF CHANGES 
 
30.1 Introduction: 
Amendment 6 consists of changes in the measurement of the primary endpoint and 
statistical analysis plan in sections 15.1 and 15.2 
30.2 Rationale: 
Since the study was designed and initiated, research from the Alzheimer’s Disease 
Neuroimaging Initiative (ADNI) and others have utilized a sub-classification of early MCI (EMCI) 
and late MCI (LMCI) to improve the understanding of effects of interventions which may be 
unique to particular early stages in the progression of AD. Based on those studies, and using 
the cognitive data available in this study, participants were classified as EMCI if baseline CDR- 
SB was less than or equal to 1.5 and LMCI if CDR-SB was greater than 1.5. 
This amendment includes the change of primary endpoint from ventricular volume to 
annualized percent change in ventricular volume. The amendment also reflects the change in 
the statistical analysis to include early and late MCI as study factors for all endpoints.

Rationale: 
 
To correct errors and add missing CSF secondary endpoint. 
 
32.0 
AMENDMENT 8: SUMMARY OF CHANGES 
 
32.1 Introduction: 
In section 15.2 we stated “Participants will also be classified as early MCI (EMCI) if baseline CDR- 
SB is less than 1.5, and late MCI (LMCI) if CDR-SB is greater than 1.5.” This doesn't say what 
happens if a patient falls at 1.5. Amendment 8 revises to state LMCI as 1.5 or greater. 
 
32.2 Rationale: 
The 1.5 cut-off more accurately depicts the early and late MCI status in that there are no 
conversions at year 1, and only 1 conversion at year 2 in the early MCI status. 
 
33.0 
AMENDMENT 9: SUMMARY OF CHANGES 
33.1 Change: 
The protocol is amended to include unblinding subjects who want to know if they received IVIG or 
placebo. Subjects participating in the extension portion of the study may be unblinded upon study 
completion. Subjects who declined participation in the extension portion of the study or who did not 
complete the study will be unblinded upon request. 
The Principal Investigator will inform subjects of their group assignment at their last study visit, and 
will not have access to individual subject data following study completion. 
This unblinding protocol was approved by the DSMC on 6/3/16. No changes were made to the 
unblinding protocol during study participation. 
 
33.2 Rationale: 
There are current and future studies for MCI and AD that exclude subjects who have had prior 
immunotherapy. If subjects remain blinded, placebo arm subjects will not have a chance to 
participate in these trials.
