Study Drug Details 
Neflamapimod 40 mg capsule or matching placebo capsule administered 
orally according to randomized treatment assignment.   
Study Design and 
Methods 
This is a Phase 2, multicenter, randomized, double-blind, placebo-
controlled, proof-of-concept study of neflamapimod 40 mg or matching 
placebo administered twice daily for 24 weeks in subjects with mild AD. 
Following completion of informed consent procedures, subjects will enter 
the Screening phase of the study. 
Two Screening visits are planned to allow most screening procedures to be 
completed and reviewed during the first visit before lumbar puncture to 
collect CSF is performed during Screening Visit 2. 
Once eligibility is confirmed and before the first dose of study drug, 
subjects will be randomly assigned on 1:1 basis to placebo or 
neflamapimod treatment.  Investigators and subjects will be blinded to the 
treatment assignment. 
Dosing will start on Day 1 following completion of all Baseline 
procedures. 
During the treatment period, subjects will return to the clinic on Days 21, 
42, 84, 126, and 168.  Telephone contacts will be conducted to determine 
subject status and assess compliance between Days 42 and 84 (Visits 5 and 
6); Days 84 to 126 (Visits 6 and 7); and Days 126 and 168 (Visits 7 and 
8).   
Episodic memory and other cognitive assessments will be performed at 
Baseline and Days 42, 84, and 168.  
Lumbar puncture will be performed, and CSF collected at Screening Visit 
2 and on Day 168. 
A Follow-up visit will be conducted 14 (±3) days following the last dose 
of study drug.

INTRODUCTION 
1.1. 
Scientific Rationale 
The investigational drug neflamapimod is a highly specific inhibitor of the intra-cellular enzyme p38 
mitogen activated protein (MAP) kinase alpha (“p38 alpha”).  Neflamapimod (VX-745) was discovered 
through a proprietary structure-based drug discovery platform at Vertex Pharmaceuticals (38TDuffy et al, 
201138T), and was licensed by EIP Pharma for development for the treatment of central nervous system 
(CNS) disorders.  Neflamapimod readily enters the brain, with brain concentrations being approximately 
2-fold higher than in peripheral blood. 
In the brain, p38 alpha is a major regulator of inflammation through effects on microglia, the major 
immune cell in the brain.  P38 alpha is also expressed in neurons, where it is directly involved in cellular 
stress-induced inhibition of synaptic plasticity and resulting formation of memory deficits (38TLynch, 
201038T; 38TPrieto, 201538T; 38TSandersen et al, 201638T).   
Pathologically, Alzheimer’s disease (AD) is defined of two distinct abnormalities: amyloid plaques and 
neurofibrillary tangles (NFTs).  The major constituent of amyloid plaques is amyloid-beta, and of NFTs is 
tau.  These 2 proteins have long been considered important in the development of AD.  While much 
scientific controversy exists on the relative contribution of the various pathogenic drivers, there is general 
agreement that the disease is a result of interplay between those 2 proteins (amyloid-beta and tau), but 
also with inflammation.  In addition, increasingly it appears the convergence point for the three drivers is 
the synapse, with synaptic dysfunction and loss being the fundamental pathogenic event within the neuron 
that leads to the defining characteristic of AD, memory deficits (38TSpires-Jones & Hyman, 201438T). 
Extensive scientific literature indicates p38 alpha is a critical contributor in the toxicity of amyloid-beta, 
inflammation (particularly the cytokine interleukin-1 beta [IL-1beta]), and tau to neurons and synapses 
(38TLi et al, 200338T; 38TLi et al, 201138T; 38TLynch, 201038T; 38TWatterson et al, 201338T; 38TBirnbaum et al, 201538T; 38TKoppensteimer 
et al, 201638T).  The most direct evidence of the contribution of p38 alpha in the development of synaptic 
dysfunction and memory deficits is from distinct animal models in which memory deficits are induced by 
amyloid-beta, inflammation, or tau, respectively.  In these models, the memory deficits are fully reversed 
with 2 to 3 weeks of treatment (38TRoy et al, 201538T; 38TAlam, 201538T; 38TMaphis et al, 201638T).  These data are 
consistent with multiple mechanistic in vitro studies in which p38 alpha plays a significant role in 
amyloid-beta and IL-1beta induced impairment of synaptic plasticity (38TWatterson et al, 201338T; 38TTong et al, 
201238T; 38TPrieto et al, 201538T).  Synaptic plasticity otherwise is the basic biochemical process by which 
information is encoded in the brain and therefore a process that is critical to learning and memory 
formation. 
Three recent scientific publications, in which p38 alpha activity was genetically knocked down by 50% in 
mice, suggest that p38 alpha activation is involved in hippocampal synaptic dysfunction.  In a 
hypertension-induced cognitive impairment model, mice with reduced p38 alpha activity had improved 
hippocampal synaptic plasticity (38TDai et al, 201638T); in another model, similar mice were protected from 
developing age-related hippocampal dysfunction and decline in neurogenesis (38TCortez et al, 201738T).  In the 
third report, and perhaps most important, genetic reduction of neuronal p38 alpha in Amyloid-Precursor-
Protein (APP) overexpressing transgenic mice resulted in improved synaptic transmission and plasticity 
in addition to reduced memory loss and amyloid pathology (38TColié et al, 201738T).

1.2. 
Pre-Clinical Pharmacology Results 
To obtain preclinical proof-of-principle, neflamapimod was tested in the aged rat model of age-related 
cognitive decline.  When tested in a water maze test, rats show cognitive deficits starting at 20 to 
22 months of age.  This deficit has been shown to be a result of impaired synaptic plasticity that is 
primarily due to inflammation (38TKelly, 200338T; 38TLynch, 201038T); however, it also due to increased levels of 
amyloid beta in the brain due to aging (38TChurch, 201438T).  Thus, aged rats provided an ideal model system to 
test whether neflamapimod could reverse impaired synaptic plasticity due to inflammation and amyloid-
beta. 
The published results (38TAlam, 201538T) showed that neflamapimod administered for 3 weeks fully reversed 
the spatial learning deficits in the morris-water-maze-test in 20- to 22-month old rats with identified 
cognitive deficits, with the performance of aged rats treated with neflamapimod at the optimal dose being 
significantly better than vehicle (placebo)- treated aged rats (P = 0.007) and being similar to that of young 
rats.  These data combined with dose-response data in previous animal and clinical studies, were then 
utilized to identify doses for the Phase 2a clinical studies.  
In advance of the Phase 2a clinical studies neflamapimod was also tested in aged-transgenic mice that 
overproduce APP and develop amyloid plaque.  In this model, neflamapimod appeared to decrease 
amyloid plaque burden in the hippocampus, a finding that provided the rationale for utilizing positron 
emission tomography (PET) amyloid scanning as a biomarker of drug effect in one of the two phase 2a 
clinical studies. 
More recently, neflamapimod was studied in an induced-stroke model in rats:  transient ischemia of 
sufficient duration was induced such that significant neurologic disability developed without mortality 
and the neurologic disability did not substantially reverse during follow-up without therapy.  These rats 
were then treated with vehicle (control) or neflamapimod.  Starting at 48-hours after stroke, 
administration of neflamapimod for 6 weeks led to substantial improvement on multiple parameters of 
neurologic function compared to vehicle controls (P < 0.001 for each of global neurologic scores, motor- 
and sensory-specific tests).  As recovery after stroke is dependent on neuronal and synaptic plasticity 
(38TChollet, 201338T), these results further confirm that neflamapimod is active in reversing impaired synaptic 
plasticity in animal models. 
Based on the scientific rationale and emerging mechanistic understanding of the effects of inhibition of 
neuronal p38 alpha (refer to Section 1.1), the demonstrated of positive pharmacological effects of 
neflamapimod may be due to reversing proteostasis defects within the neuron including impaired 
autophagy and endolysosomal dysfunction (38TAlam & Scheper, 201638T).  The proteostasis reversing potential 
of neflamapimod was recently confirmed in a human in vitro system (Down Syndrome fibroblasts), where 
neflamapimod at concentrations below 10 nM reversed endosomal abnormalities and improved lysosomal 
function (confidential data on file). 
1.3. 
Prior Clinical Experience 
Phase 1 studies in healthy subjects and a Phase 2a clinical study in patients with rheumatoid arthritis (RA) 
were previously conducted by the company that discovered neflamapimod, Vertex Pharmaceuticals.  
Approximately 150 health volunteers or patients with RA for up to 3 months received neflamapimod in 
the studies conducted by Vertex.

EIP Pharma licensed neflamapimod from Vertex in 2014 and initiated two phase 2a studies in patients 
with mild AD in May 2015:  Study 302, a 12-week treatment study conducted at VU Medical Center in 
Amsterdam, Netherlands; and Study 303, a 6-week treatment study conducted at the Early Clinical Phase 
Unit - Los Angeles, part of Parexel International.  Both studies enrolled patients with early AD, defined as 
patients with either mild cognitive impairment (MCI) with biomarker evidence of AD (i.e., “MCI due to 
AD”) or mild Alzheimer’s disease.  The Mini-Mental State Examination (MMSE) scores at baseline were 
between 20 and 28.  Neflamapimod doses of 40 mg and 125 mg twice a day (BID) were utilized in Study 
302; and effectively only 40 mg was utilized in Study 303 (one subject received 125 mg, but their plasma 
drug levels were near the middle of the 40 mg recipients in that study).  
The major efficacy findings from the Phase 2a clinical studies were: 
• 
Statistically significant improvement in tests of the recall component of episodic memory, as 
assessed by Wechsler Memory ScaleP®
P (WMS) immediate and delayed recall composite measures 
in Study 302, and Hopkins Verbal Learning Test – Revised (HVLT-R) in Study 303.  Though 
there were no placebo-control in either study, the consistency and magnitude of improvement 
indicates that there is a true drug effect, particularly in this patient population where the literature 
indicates there is less practice effects than in a healthy elderly population (see further discussion 
below). 
• 
Reductions in brain amyloid plaque load at the 40 mg dose level, as assessed in Study 302 by 
quantitative dynamic amyloid PET scan.  As neuronal p38 alpha has been shown to play a 
“critical role” in amyloid beta generation and plaque production (38TSchnoder et al, 201638T), this result 
is likely due to inhibition of p38 alpha within the neuron leading to decreased amyloid plaque 
production; thus, providing evidence of target engagement of neflamapimod in the neuron at the 
40 mg dose level.  At the higher dose level, this effect is not seen due to anti-inflammatory effect 
due to inhibition of p38 in microglia that reduces amyloid plaque clearance.   
• 
Definition of 40 mg BID as the optimal dose for neflamapimod in the treatment of AD based on 
this does level having positive effects on both recall component of episodic memory and amyloid 
plaque load. 
• 
In addition, neflamapimod at a dose level up to 125 mg BID for 12 weeks was well tolerated in 
patients with AD.  In addition, neflamapimod was confirmed to be blood-brain-barrier penetrant 
in humans. 
Because the episodic memory tests inform directly on the design of the current study, the results are 
discussed in more detail in this section. 
In Study 302 (12-week study in Netherlands), episodic memory was evaluated using the Dutch version of 
the WMS scale utilizing both verbal and visual information:  Logical Memory test, in which subject is 
read a story; Verbal-Paired Associates, in which subject is given pairs of words and asked remember 
which words go together; and Visual Reproduction, in which subject is given drawings of specific shapes.  
Subjects were then asked to recall the information within each test both in an immediate (WMS-
Immediate Recall composite) and delayed (WMS-Delayed Recall composite) basis.  The WMS was 
administered at baseline (i.e., before first dose of neflamapimod), after 28 days of treatment, and at end of 
treatment on Day 84.   


EIP-VX17-745-304, Version 2.0, 27 August, 2018 
Page 18 of 49

Mean WMS immediate recall composite scores increased from 48.4 (±3.8) at baseline to 58.4 (±4.3) at 
Day 84 (n=15; p=0.005 by Wilcoxon sign rank test for improvement).  Mean WMS delayed recall 
composite scores increased from 13.2 (±2.3) at baseline to 22.1 (±4.1) at Day 84 (p<0.001).  Seven of 
8 patients in 40 mg group and 6 of 7 in 125 mg group showed improvement from baseline in immediate 
recall composite score; 8 of 8 patients in 40 mg group and 6 of 7 in 125 mg group showed improvement 
from baseline in delayed recall composite score. 
To further understand the impact of neflamapimod on episodic memory as assessed by WMS, an analysis 
of the relationship between plasma drug (neflamapimod) concentrations and outcome on WMS immediate 
and delayed recall tests was conducted.  Using a standard linear pharmacokinetic-pharmacodynamic (PK-
PD) regression model, a highly significant positive correlation was established between plasma drug 
levels and level of improvement at Day 84 in combined WMS-immediate and delayed recall (p=0.001).  
Moreover, plasma drug levels explained 70% (i.e., rP2
P=.70) of the variance in change (improvement) from 
baseline to end-of-treatment.  These statistics strongly argue that the improvement seen in episodic 
memory in this study was primarily due to neflamapimod treatment, and not due to chance or practice 
effects.  In addition, the concentration dependency of the effects on episodic memory in the plasma drug 
levels achieved with the dose range of 40 mg to 125 mg that there is no rationale for going to lower doses, 
as they would simply lead to lower efficacy; while the difference in plasma drug concentrations achieved 
with the two doses, and therefore effect on episodic memory, were not substantial. 
In Study 303 (6-week study in Los Angeles), the HLVT-R was utilized to assess episodic memory.  In 
this test, 12 specific words from a list are provided verbally, and subject asked to recall ask many words 
as possible.  Two scores are calculated: 
• 
Total (Immediate) Recall Score (0-36):  combined score of 3 consecutive trials immediately 
following provision of words.   
• 
Delayed Recall Score (0-12): Number of words recalled when subject is asked 20-25 minutes 
after initial trials to recall as many of the words originally provided. 
A strength of the HVLT-R is that 5 different validated version exist that incorporate different set of 
words.  Due to the use of these different versions during the course of a clinical study, there is essentially 
no practice effect (Benedict,38T et al, 199838T) with repeated administration. 
Mean Total Recall improved from 19.1 (±1.5) at Baseline to 22.6 (±2.1) at week 6 (p=0.015 for 
improvement from baseline); Delayed Recall increased from 5.4 (±0.6) to 7.5 (±1.1) (p=0.028 for 
improvement from baseline).  Median increase in Total Recall score was 4.5 (range: -2.5 to +9.5), with 
only one subject with a decrease during treatment.  Particularly with the use of alternate versions that 
should minimize “placebo effects”, the consistency of improvement and statistics indicates that the 
improvements in episodic memory seen in Study 303 are due to neflamapimod treatment.

To further evaluate and compare the episodic memory results, treatment effect sizes (ES; called Cohen’s d 
in statistics) were calculated for each study/measure.  The results are shown in the following table: 
 
Study 303 (N=15) 
(Wechsler Memory Scale) 
Study 303 (N=8) 
(HLVT-R) 
Immediate Recall 
.59 
.69 
Delayed Recall 
.69 
.86 
 
The ES calculations show first that the results are very similar between the two studies, i.e., there is a high 
degree of consistency between the studies despite the use of different measures and tests being applied in 
different languages/cultures.  The magnitude of the ES ranging between 0.59 and 0.86 also argues for a 
true drug effect, as in MCI and Alzheimer’s patient population, ES for improvement in placebo groups are 
generally <0.2 (38TGoldberg et al, 201538T) in short-term studies, and often show either no change or worsening 
after 12 weeks or longer follow-up (38TScheltens et al, 201138T; 38THassenstab et al, 201538T).  In addition, as ES >0.5 
is generally taken as being clinically meaningful, ES calculations allows an assessment of whether the 
magnitude of treatment effect is clinically relevant; which in this case appears to be so.   
MMSE scores were evaluated in the 2 studies  Though the variability in MMSE results and the samples 
sizes did not allow one to do statistical analyses, the overall trends were encouraging as 11 of 14 subjects 
at the 40 mg dose level across the 2 studies that had baseline and end-of-treatment had at least a 1-point 
improvement in MMSE score. 
With the consistent effect on recall component of episodic memory across the 2 studies, and corroboration 
using 2 different assessment tools in distinct patient populations, the phase 2a clinical data provide 
preliminary evidence that neflamapimod is pharmacologically active in a manner that is consistent with 
the scientific rationale and preclinical data that indicate the potential to reverse synaptic dysfunction in 
the hippocampus.  The objective of the current study then is to demonstrate proof-of-concept for 
neflamapimod by replicating the phase 2a results of improving episodic memory function in a placebo-
controlled study.  In addition, a general clinical measure of cognition and function (Clinical Dementia 
Rating Scale [CDR]) will be assessed both to determine whether there is evidence of improvement and 
estimating potential treatment effects to support Phase 3 study design. 
From a mechanism standpoint the expected effect of neflamapimod on episodic memory through 
reversing synaptic dysfunction, possibly through reversing endolysosmal dysfunction within neurons.  In 
animals, the biomarker of inhibiting reversing synaptic dysfunction through inhibiting neuronal p38α is 
reduced amyloid beta generation and tau aggregation (38TColié et al, 201738T; 38TMaphis et al, 201638T), which in 
humans might be expected to lead to reduced CSF Aβ peptides levels and CSF total or phospho-tau.  
Therefore, to provide additional support of an objective drug effect and to support mechanistic 
understanding of drug effect, CSF will be collected at baseline and at end-of-treatment to assess effects of 
neflamapimod on CSF levels of total tau, p-tauR181
R, AβR1-40
R, AβR1-42, and neurogranin.  In addition, 
neurofilament light chain in CSF, recently identified as potential marker of neurodegenerative diseases 
associated with proteostasis defects (38TBacioglu, 201638T) will be evaluated.

INVESTIGATIONAL PLAN 
3.1. 
Overall Study Design and Plan 
This is a Phase 2, multicenter, randomized, double-blind, placebo-controlled, proof-of-concept study of 
neflamapimod 40 mg or matching placebo administered twice daily for 24 weeks in subjects aged 55 to 
85 years with CSF biomarker-confirmed AD; with global CDR score of 0.5 or 1.0, with CDR memory 
subscore of at least 0.5, and MMSE scores between 20 and 28, inclusive. 
A schedule of assessments is presented in Table 6-1.  
3.1.1. 
Screening 
Following completion of informed consent procedures, subjects will enter the Screening phase of the 
study. 
Two screening visits are planned to allow most screening procedures to be completed and reviewed 
during the first visit before lumbar puncture to collect CSF to be performed on Screening Visit 2.  
All screening assessments should be conducted within 42 days of Day 1 (first dose of study drug). 
3.1.2. 
Treatment Period 
Once eligibility is confirmed and before the first dose of study drug, subjects will be randomly assigned 
to receive neflamapimod or placebo; refer to Section 5.4 for details regarding assignment to treatment 
group. 
Dosing will start on Day 1, following completion of all Baseline procedures.  During the treatment period, 
subjects will return to the clinic on Days 21, 42, 84, 126, and 168.  Telephone contacts will be conducted 
to determine subject status and assess compliance between Days 42 and 84 (Visits 5 and 6); Days 84 to 
126 (Visits 6 and 7); and Days 126 and 168 (Visits 7 and 8). 
3.1.3. 
Follow Up 
A Follow-up Visit will be conducted 14 (±3) days following the last dose of study drug.  
3.1.4. 
Early Discontinuation 
Subjects who prematurely discontinue study drug for any reason will be asked to return to the clinical site 
for an Early Termination visit within 3 days following the last study drug dose; if it is determined that the 
subject will discontinue study drug while at the study center for a scheduled visit, then the Early 
Termination visit should be conducted at that time.  These subjects will also be asked to return to the 
clinical site for a Follow-up Visit 14 (±3) days following the last study drug dose.   
Every effort should be made to ensure a subject returns for this visit. 
Refer to Section 4.3 for details regarding removal of subjects from treatment. 
3.2. 
Discussion of Study Design 
The primary objective of assessing episodic memory was chosen to provide a robust assessment of the 
potential of neflamapimod to reverse hippocampal dysfunction in subjects with mild AD.  Defects in 
episodic memory are a defining characteristic of AD and is one of earliest manifestations of cognitive 


EIP-VX17-745-304, Version 2.0, 27 August, 2018 
Page 22 of 49

Confidential 
dysfunction in the disease process (38TGold & Budson, 200838T; 38TTromp et al, 201538T).  In addition, neflamapimod 
demonstrated effects on episodic memory in the Phase 2a studies. 
The HVLT-R test was chosen as the assessment tool for the primary endpoint because it has alternative 
versions validated in multiple cultural and language contexts, has high test-retest reliability, and shows 
good short-term stability (i.e., no practice effects) in subjects with mild AD (38TPhillips et al, 201238T). 
3.2.1. 
Rationale for Dose Selection 
The dosing regimen of 40 twice daily for 24 weeks is based on available efficacy (pharmacological 
activity; Section 3.2.1.1) and safety (Section 3.2.1.2) data.   
3.2.1.1. 
Efficacy Considerations 
The 40 mg BID regimen was chosen because PK-PD modeling (plasma drug concentration response) 
correlations indicated a plasma drug concentration dependency on the effects on episodic memory that 
argues against going to lower doses and only modest further increase in efficacy with utilizing 125 mg 
dose level, while the loss of an amyloid plaque load effect at 125 mg dose level provides a specific reason 
not to increase the dose above 40 mg.  The PK-PD modeling was also consistent with the in vitro potency 
of the drug and predicted doses for optimal cognitive effects based on pre-clinical studies (38TAlam, 201538T).  
Moreover, the 40 mg dose level provides an appropriate safety margin relative to findings in chronic 
toxicology findings in the dog (Section 3.2.1.2). 
3.2.1.2. 
Safety Considerations 
Based on the clinical experience to date at higher doses and the results from animal toxicology studies, 
the neflamapimod dose of 40 mg BID and lower is expected to be well tolerated and to have a low risk of 
drug toxicity.  
In the Phase 2a studies (Study 303) of 6- or 12-weeks neflamapimod dosing in patients with mild AD, a 
total of 25 subjects were enrolled.  With regard to safety, neflamapimod was well tolerated, with 24 of 
25 subjects completing their scheduled dosing period (8 completed 6 weeks neflamapimod 
administration, and 16 completing 12 weeks neflamapimod administration).  The one subject who 
discontinued early did so within the first week of study drug administration due to an adverse event (AE) 
of vomiting, attributed primarily to persistent CSF leakage after the predose/baseline CSF collection.  
There were no severe or serious AEs reported.  The most common AEs across the 2 studies were mild 
somnolence (sleepiness or drowsiness) reported in 5 patients, and self-limited mild diarrhea (loose stools) 
reported in 4 patients.  There was also one event of moderate diarrhea, which was considered not related, 
as the event did not recur during additional 8 weeks of treatment after having resolved during a brief 
treatment interruption.  No treatment-related or clinically relevant trends in the analysis of safety 
laboratory and 12-lead electrocardiogram (ECG) parameters were observed.  More specifically, there 
were no abnormalities in liver function tests (LFTs), nor any trends in changes in LFT parameters, noted 
in either study.  LFT abnormalities, specifically increases in liver transaminases, were seen in 10% to 
15% of patients in a prior study in patients with RA at a dose of 250 mg BID for 3 months.  Due to the 
use of different formulations in the RA studies, the plasma drug concentrations were 4- to 5-fold higher 
than in the Phase 2a mild AD studies. 
The 40 mg BID dose level provides a 5-fold margin based on plasma drug levels to no adverse effect 
level and 10-fold margin to minimal and/or equivocal findings for hematological, hepatic and

Neflamapimod 40 mg capsule(s) or matching placebo capsules will be administered orally, BID with a 
meal or snack for 24 weeks.  Doses should be taken within 30 minutes following a meal or snack (i.e., 
breakfast and dinner) no less than 8 hours apart and at approximately the same times each day throughout 
the study. 
All subjects will receive matched (by size and color) capsules that contain 40 mg neflamapimod or 
placebo, respectively. 
The first dose of study drug and the morning dose on Day 21 will be administered at the clinical site.  
The Investigator or other designated, qualified site personnel should review dosing instructions with the 
subject.  Subjects will be instructed to return all study containers, regardless of whether empty or 
containing unused study drug. 
5.1. 
Packaging and Labeling 
EIP Pharma will supply placebo or neflamapimod capsules on an individual subject basis.   
Both neflamapimod and placebo capsules are opaque in color.  Label details will be in accordance with 
local and national requirements.  
5.2. 
Study Drug Supply, Storage, and Handling 
Study drug will be supplied to the site on a per-subject basis.  
Capsules will be supplied in blister cards, which each blister card containing 16 capsules (i.e., 1-week 
supply of study, with two extra capsules).  The blister cards will be packaged in cartons containing a 
3-week supply of study drug (i.e., 3 blister cards per carton). 
Neflamapimod capsules should be stored at 59 to 86°F (15–30°C; controlled room temperature), and 
should not be exposed to heat in excess of 86°F (30°C) or to high humidity. 
While at the clinical site, study drug access should be limited to the Investigator and other qualified site 
personnel. 
5.3. 
Drug Accountability, Disposal, Return, or Retention of Unused 
Study Drug 
The site designated pharmacist or other qualified personnel will document receipt from Sponsor, 
dispensing to subjects, and return to site from subject on the drug accountability log(s).   
Subjects will be instructed to return all blister packs, regardless of whether empty or containing unused 
study drug.  EIP Pharma or designee will review accountability records throughout the conduct of the 
study.  
The site should maintain all study drug containers (used and unused) until final review of accountability is 
conducted by the EIP Pharma or designee, and instructions regarding return or disposal, as applicable, are 
provided.

5.4. 
Method of Assigning Subjects to Treatment Group 
After subjects have completed Screening Visit 2 and are deemed eligible, they will be randomized in a 
blinded manner to either placebo or neflamapimod treatment utilizing a central Interactive Web Response 
System (IWRS).  Study drug for the entire 24-week period will then be sent on a per subject basis to the 
site.  Randomization will be stratified by 1) background AD-specific therapy (cholinesterase inhibitor or 
memantine versus no cholinesterase inhibitor or memantine); and 2) CDR-Global Score of 0.5 versus 1.0. 
5.5. 
Study Blinding and Breaking the Blind 
Subjects and site personnel associated with study conduct will be blinded to treatment assignment. 
During the conduct of the study, the blind may be broken on an individual subject basis in the event of an 
emergency where it is necessary for the Investigator to know which treatment the subject is receiving 
before the subject can be treated.  The code may also be broken if someone not in the study uses study 
drug (e.g., if a child in the participant’s household takes study drug, the blind may be broken to determine 
treatment for the child.)  
When it is necessary to break the blind, the researcher may unblind the treatment immediately 
(i.e., without prior notice to the medical monitor, sponsor, or other) but must notify the Institutional 
Review Board (IRB)/Independent Ethics Committee (IEC) and the Medical Monitor and/or Sponsor as 
soon as possible, preferably by telephone and then in writing, regarding the necessity of code breaking. 
When possible, the Medical Monitor should be contacted to discuss reasons for breaking the blind.  
If the code is broken for a subject, this must be documented in the electronic case report form (eCRF) and 
source documents, together with the reasons for breaking the code. 
5.6. 
Dose Modification for Toxicity 
No dose modifications are permitted during the study.  If a subject is unable to tolerate the assigned study 
drug dose then the subject should be discontinued from study drug treatment (Section 4.3). 
5.7. 
Prior and Concomitant Therapy 
Any medications taken from Screening through Follow-up Visit, including all prescription and over-the-
counter medications as well as supplements, will be documented in the subject’s source document and in 
the eCRF.  
At study entry, any subject taking a drug for AD (e.g., donepezil or other cholinesterase inhibitors or 
memantine) must have been on a stable dose for at least 2 months (refer to Section 4).  Furthermore, the 
dose must remain unchanged during the study, unless required for management of AEs. 
While drug-drug interaction studies have not been conducted, in vitro testing indicates that neflamapimod 
is metabolized by oxidation in the liver by the CYP system (combination of CYP3A4 and CYP2C19 
isozymes).  Until the metabolism is better characterized, concomitant strong inhibitors of CYP3A4 are 
prohibited and strong inducers of CYP3A4 should be used with caution in subjects receiving 
neflamapimod, as the use of such drugs in could impact neflamapimod metabolism in subjects who have 
an underlying CYP2C19 genotypic variant that impacts activity of that CYP2C19.  Subjects will be tested 
for CYP2C19 genotype at baseline to assess any differences in neflamapimod levels and effect (see 
Section 6.2.5).

The following medications are prohibited during study participation: 
• 
Strong CYP3A4 inhibitors (see Table 5-1). 
• 
Any other investigational drug.  If a subject has previously participated in a study of an 
investigational drug, last dosing must have occurred 3 months or 5 half-lives of the investigation 
drug, whichever is longer, before enrollment in this study.  
• 
Any anti-tumor necrosis factor-alpha therapy. 
• 
Typical and atypical antipsychotics. 
The Medical Monitor should be contacted with any questions regarding concomitant use of medications 
that are thought to modulate CYP3A4 activity.

Contraception and Pregnancy 
This section should be read in conjunction with the selection criteria that relate to age and contraception: 
• 
Inclusion criterion #1 (Section 4.1) and Exclusion criteria #12 and #13 (Section 4.2)  
No signs of embryo-fetal toxicity or teratogenic effects of neflamapimod were observed in rats.  Testing 
in rabbits was not performed due to lack of exposure following administration of the neflamapimod 
formulation.  No human studies of effects of neflamapimod on conception, pregnancy, or lactation have 
been performed.  Females should not be exposed to neflamapimod if pregnant, breastfeeding, or 
attempting to conceive.  The following guidelines for contraception should be followed from before first 
dose on Day 1 through 91 days following the last dose of study drug: 
Female subjects of child-bearing potential (have not experienced menopause and have not had a 
hysterectomy or bilateral oophorectomy/salpingo-oophorectomy) are not eligible for the study.  Female 
subjects who have experienced menopause within the previous year must have a negative pregnancy test 
during Screening and must use at least 1 of the following contraceptive methods: complete abstinence 
regardless of menstrual cycle timing, contraceptive (oral, transdermal, injectable, or implantable), 
intrauterine device, or barrier method of contraception. 
Male subjects with female partners of child-bearing potential must use at least 1 of the following 
contraceptive methods: complete abstinence, vasectomy, or barrier method of contraception. 
Pregnancy of a female partner of a male subject (and, although unlikely, in a female subject) should be 
reported to the Investigator, and, in turn, the pregnancy should be reported to Worldwide Clinical Trials 
within 24 hours of the Investigator’s awareness of the pregnancy.  In the unlikely event a female subject 
becomes pregnant, study drug will be permanently discontinued and the subject will be discontinued from 
the study. 
With proper informed consent (separate pregnancy informed consent form), the subject or partner will be 
followed through the completion of the pregnancy and outcome of the pregnancy reported, and the infant 
will be followed for 12 months after birth.

5.9. 
Activity Restrictions 
The Investigator is to advise subjects to take measures to minimize exposure to ultraviolet light during 
study participation through 2 weeks after the last study drug dose.   
5.10. 
Treatment Compliance 
Treatment compliance will be assessed by reviewing the count of returned capsules at each visit.  Any 
apparent discrepancies between quantity of capsules returned and the number expected based on dosing 
schedule will be discussed with the subject to ensure an understanding of dosing instructions.  
Patients will be provided with identification cards on which they will record the date and time of study 
drug administration prior to each scheduled study center visit. 
Repeated non-compliance with dosing instructions may necessitate discontinuation from the study, based 
on the Investigator’s judgment (Section 4.3).

Study Assessments 
6.2.1. 
Baseline and Disease Characteristics  
Details regarding AD history will be collected during Screening, as specified in the eCRF. 
6.2.2. 
Columbia-Suicide Severity Rating Scale 
The C-SSRS is a clinician-administered instrument that assesses suicidal ideation and behavior (38TPosner, 
201138T). The “Baseline” version of the instrument will be administered to subjects during Screening, and 
the “Since Last Visit” version will be used at subsequent time points specified in Table 6-1. 
6.2.3. 
Computed Tomography/Magnetic Resonance Imaging 
The subject must have had MRI or CT scan within 2 years of Screening, with findings negative for 
evidence of other neurodegenerative or other brain disease that could account for their cognitive 
symptoms.  If MRI or CT has not been performed within 2 years before Screening and/or results are not 
available, MRI or CT scan must be performed as part of Screening to exclude other disease.  MRI/CT 
results should be available and reviewed before Screening lumbar puncture is performed (see Section 
6.2.4). 
6.2.4. 
Lumbar Puncture 
LP will be performed at Screening Visit 2 and at the End-of-Treatment (Day 168 or Early Termination 
visit in subjects who discontinue treatment early).  The End-of Treatment LP is to be performed within 


EIP-VX17-745-304, Version 2.0, 27 August, 2018

±2 days after the last study drug dose.  There is no need to perform the LP for subjects who discontinue 
prior to Visit 5 (Day 42). 
Kits for collection of CSF samples will be provided.  CSF levels of total tau, p-tauR181
R, AβR1-40
R, AβR1-42
R, 
neurogranin, and neurofilament light chain will be determined by enzyme-linked immunosorbent assay at 
a designated central laboratory.  
6.2.5. 
Genotyping and Apolipoprotein E4 Testing 
A blood sample will be collected from all subjects at Visit 3 (Day 1) for CYP2C19 genotyping; such 
testing is mandatory.  The CYP2C19 gene encodes for a drug metabolizing enzyme that accounts for 
approximately half the metabolism of neflamapimod.  (The other is the CYP3A4 enzyme).  As there are 
known polymorphisms in CYP2C19, particularly in Asian populations, that reduce the function of this 
enzyme, the PK profiles in individual subjects may be impacted CYP2C19 genotype (38TFricke-Galindo et 
al, 201638T).  PK profiles will be obtained in all subjects and correlated against CYP2C19 genotype (see 
Section 6.2.8 and Section 8.4).  An aliquot of blood from this sample may also be used for measurement 
of apolipoprotein E4; such testing is optional.  Results will be available to study sites and may be 
discussed with the subjects only after the clinical study report has been completed.  
6.2.6. 
Mini-Mental State Examination/CDR 
The MMSE (Folstein et al, 1975) consists of 11 tests of orientation, memory (recent and immediate), 
concentration, language, and praxis.  Scores range from 0 to 30, with lower scores indicating greater 
cognitive impairment.  It is based on the performance of the subject and takes approximately 5 to 10 
minutes to administer. 
The CDR (Hughes, 1982) is a semi-structured interview resulting in a semi-quantitative scoring of 
cognitive impairment in milder and more progressed forms of dementia.  It is sensitive in both AD 
dementia and Mild Cognitive Impairment (MCI), and is an approved regulatory endpoint recognized by 
the FDA.  The CDR interview is to be conducted with the subject and Caregiver by an experienced and 
certified clinician.  The CDR yields both a global and an SB score.  The global CDR rating, along with 
the memory box score, will be used to determine a subject’s eligibility for inclusion.  In addition, the 
CDR-SB score will utilized to evaluate cognitive and functional changes from baseline to Visit 6 and 
Visit 8.   
Standardized MMSE (Version 2.0) and CDR will be conducted by the Investigator or designee. 
6.2.7. 
Episodic Memory Tests - HVLT-R and WMS 
The HVLT-R is a verbal learning and memory test, with 6 validated alternate forms.  Each form contains 
12 nouns, 4 words each from 1 of 3 semantic categories (e.g., precious gems, articles of clothing, 
vegetables), to be learned, and repeated back to the evaluator over the course of 3 learning trials.  
Approximately 20–25 minutes later, a delayed recall trial and a recognition trial are completed.  The 
delayed recall requires free recall of any words remembered.  The recognition trial is composed of 
24 words, including the 12 target words and 12 false-positives, 6 semantically related, and 6 semantically 
unrelated.  The 3 learning trials are combined to calculate a total recall score; the delayed recall trial 
creates the delayed recall score. 
For WMS, Logical Memory I & II & II-(Recognition), VPA I & II & II-(Recognition), and Visual 
Reproduction I & II & II-(Recognition) will be applied. 


EIP-VX17-745-304, Version 2.0, 27 August, 2018 
Page 36 of 49 
EIP Pharma, Inc. 
Confidential 
The HVLT-R and WMS tests must be performed sequentially within the day; with the HVLT-R to be 
conducted first and completed (including delayed recall component), prior to commencing WMS test. 
6.2.8. 
Pharmacokinetic Sampling 
On Day 21, the subject must not take their morning dose of study drug; instead, the morning dose of the 
study drug will be administered with a meal or snack in the clinic, and blood samples will be collected for 
PK (drug concentration) testing immediately prior to and 2.5 hours after study drug administration (i.e., at 
predicted time point for peak drug concentration after dose administration).  On Day 42 and Day 84, 
blood samples will also be collected for PK sample concurrently with clinical laboratory test sampling 
during the time of their visit to the clinic.  Subjects should take their morning dose of study drug at home 
with a meal or snack on Day 42 and 84 on their regular schedule and record the time of their morning 
dose.  Day 42 and Day 84 PK samples will be collected together with the safety laboratory samples at the 
clinic, the time of the PK sampling must be recorded.  
Refer to the Laboratory Manual for details regarding PK sample collection, processing, and shipment.   
6.2.9. 
Physical Examination and Vital Signs 
Physical examination will include a review of all body systems and measurement of weight, per each 
Investigators standard practice.  Physical examination findings will be documented in the subject’s source 
documents.   
Vital signs include measurement of blood pressure, pulse, respiratory rate, and body temperature.  
Any physical examination finding or vital sign measurement that represents a worsening from Baseline 
condition and is considered by the Investigator to be clinically significant will be recorded as an AE (see 
Section 7). 
6.2.10. 
12-Lead Electrocardiogram 
A 12-lead ECG will be performed using validated machinery available locally to each clinical site.  Each 
report will be reviewed by the Investigator for qualified sub-investigator and assessed as normal, 
abnormal – not clinically significant, or abnormal – clinically significant.  Abnormal, clinically significant 
findings that represent a worsening from Baseline will be recorded as an AE. 
6.2.11. 
Clinical Laboratory Assessments 
Two blood samples will be collected at the time points specified in Table 6-1 for assessment of routine 
chemistry and hematology analytes.  One additional blood sample will be collected for coagulation 
studies at the time points specified in Table 6-1.  
Kits for clinical laboratory assessments will be provided by and samples will be analyzed at a designated 
central laboratory.  Additional details are provided in the Laboratory Manual.

Withdrawal of Subjects 
A subject may be discontinued from study treatment at any time if the subject, the Investigator, or the 
Sponsor feels that it is not in the subject’s best interest to continue.  The following is a list of possible 
reasons for study treatment discontinuation: 
• 
Subject withdrawal of consent (or assent) 
• 
Subject lacks ability to provide continued informed consent (or assent) and/or sound judgement 
as to whether to continue in the study 
• 
Subject develops active suicidal ideations or attempts suicide 
• 
Subject is not compliant with study procedures

• 
AE that in the opinion of the Investigator would be in the best interest of the subject to 
discontinue study treatment 
• 
Protocol violation requiring discontinuation of study treatment 
• 
Lost to follow-up 
• 
Sponsor request for early termination of study 
If a subject is withdrawn from treatment due to an AE, the subject will be followed and treated by the 
Investigator until the abnormal parameter or symptom has resolved or stabilized.   
A subject may be withdrawn from the study at any time if the subject, the Investigator, or the Sponsor 
feels that it is not in the subject’s best interest to continue.   
All subjects are free to withdraw from participation at any time, for any reason, specified or unspecified, 
and without prejudice. 
Reasonable attempts will be made by the Investigator to provide a reason for subject withdrawals.  The 
reason for the subject’s withdrawal from the study will be specified in the subject’s source documents.   
Subjects who withdraw from the study treatment and/or study for a reason prior to Day 21 will be 
replaced.  
Refer to Table 6-1 for assessments to be performed for subjects who prematurely discontinue study drug.

ADVERSE EVENTS AND SERIOUS ADVERSE 
EVENTS/SAFETY REPORTING 
The Investigator is responsible for reporting of events meeting the criteria and definition of an AE or SAE 
as provided in this protocol.  
7.1. 
Definitions and Criteria  
7.1.1. 
Adverse Events  
Per International Council for Harmonisation (ICH) E2A: An AE is 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 (including an abnormal laboratory finding, for example), symptom, or 
disease temporally associated with the use of a medicinal product, whether or not considered related to 
the medicinal product.  
Medical interventions such as surgeries, diagnostic procedures, and therapeutic procedures are not AEs 
but the action taken to treat the medical condition.  They should be recorded as treatment of the AEs. 
7.1.2. 
Serious Adverse Events 
An SAE or reaction is any untoward medical occurrence that at any dose:  
• 
Results in death  
• 
Is life-threatening  
• 
Requires inpatient hospitalization or prolongation of existing hospitalization  
• 
Results in persistent or significant disability or incapacity  
• 
Is a congenital anomaly or birth defect  
• 
Is an important medical event (e.g., intensive treatment in an emergency room or at home for 
allergic bronchospasm; blood dyscrasias, or convulsions that do not result in hospitalization; or 
development of drug dependency or drug abuse; malignancy)  
Note: The term “life-threatening” in the definition of “serious” refers to an event in which the subject was 
at risk of death at the time of the event; it does not refer to an event that hypothetically might have caused 
death if it were more severe.  
Medical and scientific judgement should be exercised in deciding whether expedited reporting is 
appropriate in other situations, such as important medical events that may not be immediately life-
threatening or result in death or hospitalization, but may jeopardize the subject or may require 
intervention to prevent one of the other outcomes listed in the definition above.  These should also usually 
be considered serious.  
Examples of such events are intensive treatment in an emergency room or at home for allergic 
bronchospasm; blood dyscrasias, or convulsions that do not result in hospitalization; or development of 
drug dependency or drug abuse.  


EIP-VX17-745-304, Version 2.0, 27 August, 2018 
Page 40 of 49 
EIP Pharma, Inc. 
Confidential 
Seriousness (not severity) serves as a guide for defining regulatory reporting obligations.  An SAE is not 
necessarily severe; e.g., an overnight hospitalization for a diagnostic procedure must be reported as an 
SAE even though the occurrence is not medically serious.  By the same token, a severe AE is not 
necessarily serious: nausea of several hours’ duration may be rated as severe but may not be considered 
serious. 
7.1.3. 
Unexpected Adverse Drug Reactions  
An unexpected adverse drug reaction (ADR) is a reaction for which the nature or severity is not consistent 
with the applicable product information (Investigator’s Brochure, Package Insert for marketed products).  
Until product information is amended, expedited reporting is required for additional occurrences of the 
reaction.  Reports that add significant information on specificity or severity of a known, already 
documented SAE constitute unexpected events.  For example, an event more specific or more severe than 
described in the Investigator's Brochure would be considered "unexpected.”  Specific examples would be 
(a) acute renal failure as a labeled ADR with a subsequent new report of interstitial nephritis and (b) 
hepatitis with a first report of fulminant hepatitis.  
Guidance on reporting AEs and SAEs is described in Section 7.2. 
7.1.4. 
Abnormal Laboratory Values 
Any abnormality in a laboratory value that is new in onset or which has worsened in severity or frequency 
from the baseline condition and meets 1 of the following criteria will be recorded on the AE pages of the 
eCRF:  
• 
Requires therapeutic intervention or diagnostic tests. 
• 
Leads to discontinuation of investigational product. 
• 
Has accompanying or inducing symptoms or signs. 
• 
Is judged by the Investigator as clinically significant. 
7.1.5. 
Assessing Intensity and Relationship  
All AEs will be assessed on 2 descriptive parameters: intensity and relationship to the investigational 
product: 
• 
Intensity refers to the severity of an event and references impact on a subject’s functioning. 
• 
Relationship refers to the likelihood that the event being assessed was caused by the 
investigational product. 
Intensity 
Each AE will be classified according to the following criteria: 
Mild: 
The AE does not interfere in a significant manner with the subject’s normal level of 
functioning. 
Moderate: 
The AE produces some impairment of functioning, but is not hazardous to the 
subject’s health. 


EIP-VX17-745-304, Version 2.0, 27 August, 2018 
Page 41 of 49 
EIP Pharma, Inc. 
Confidential 
Severe: 
The AE produces significant impairment of functioning or incapacitation and is a 
definite hazard to the subject’s health. 
When changes in the intensity of an AE occur more frequently than once a day, the maximum intensity 
for the experience should be noted.  If the intensity category changes over a number of days, those 
changes should be recorded separately (with distinct onset dates). 
Relationship 
Each AE will be assessed as to its relationship to the investigational product, based on the following 
criteria.  Although the attribution by the Investigator will be collected for reported events, for analytic 
purposes a temporal association with the use of the investigational product will be assumed sufficient for 
at least plausible association. 
Not related: 
No causal relationship exists between the investigational product and the AE, but an 
obvious alternative cause exists, e.g., the subject’s underlying medical condition or 
concomitant therapy. 
Possibly related: 
A connection with the administration of the investigational product appears unlikely, 
but cannot be ruled out with certainty.  An AE may be considered possibly related if 
or when it meets 2 of the following criteria: (1) it follows a reasonable temporal 
sequence from administration of the investigational product; (2) it could not readily 
have been produced by the subject’s clinical state, environmental or toxic factors, or 
other modes of therapy administered to the subject; or (3) it follows a known pattern 
of response to the investigational product. 
Related: 
There is a reasonable/plausible possibility that the AE may have been caused by the 
investigational product. 
When assessing the relationship to the investigational product, the following criteria will be considered: 
• 
Positive rechallenge 
• 
Positive dechallenge (resolution upon stopping suspect the investigational product, in absence of 
other intervention or treatment) 
• 
Known class effect 
• 
Biological plausibility 
• 
Lack of alternative explanation—concomitant drug or disease 
7.2. 
Reporting Procedures and Requirements 
7.2.1. 
Adverse Events 
AEs occurring from when the subject signs the informed consent form (ICF) until the last study event will 
be recorded.  Any AEs occurring before the start of treatment (i.e., before the first dose of the 
investigational product)” will be recorded in the medical history.  Also, the sign, symptom, or disease 
present before starting the treatment period are only considered AEs if they worsen after starting the 
treatment period. 


EIP-VX17-745-304, Version 2.0, 27 August, 2018 
Page 42 of 49 
EIP Pharma, Inc. 
Confidential 
If the Investigator detects an AE in a study subject after the last scheduled follow-up visit and considers 
the event possibly related or related to prior study treatment, the Investigator should report it to 
Worldwide Clinical Trials.  
The Investigator should report all AEs on the AE page(s) of the eCRF and source documents, regardless 
of seriousness, severity, and causality.  Whenever possible, an AE will be reported using a diagnostic 
term, (e.g., “common cold” or “upper respiratory infection” rather than “runny nose, cough, mild fever”) 
and should be described with the attributes described in Section 7.1.5. 
7.2.2. 
Serious Adverse Events 
Each AE will be assessed to determine whether it meets seriousness criteria (Section 7.1.2).  If the AE is 
considered serious, the Investigator should report this event to Worldwide Clinical Trials as outlined 
below and also to the IRB/IEC according to its standard operating procedures. 
If the Investigator detects an SAE in a study subject after the last scheduled follow-up visit, and considers 
the SAE related or possibly related to prior study treatment, the Investigator should report it to Worldwide 
Clinical Trials. 
SAE Reporting: 
E-mail:  drugsafety@worldwide.com 
Telephone:  +44 (0)115 922 0960 
All information about SAEs will be collected and reported via the SAE form and sent by e-mail message 
or facsimile (contact information will be contained in the investigator site file).  The Investigator should 
send the initial report within 24 hours of becoming aware of the SAE.  At minimum, the initial report 
should include the following information: 
• 
Event 
• 
Study code 
• 
Subject number, initials, and date of birth 
• 
Investigational product 
• 
Reporter name and contact information 
In the case of a “minimum report” (one that solely comprises the information bulleted above), a more 
detailed follow-up report should be sent as soon as more information becomes available but no later than 
7 calendar days after the date of the initial report.  Each SAE should be followed up until resolution or 
stabilization and for reported deaths, the Investigator should supply Worldwide Clinical Trials and the 
IRB/IEC with any additional requested information (e.g., autopsy reports and terminal medical reports). 
The original SAE form should be kept at the study site.  The Sponsor or its designee will be responsible 
for determining and in turn, reporting SAEs to regulatory authorities according to the applicable 
regulatory requirements. 
SAEs that are ongoing at the Follow-up visit should be followed until resolved.

DATA MANAGEMENT AND STATISTICAL ANALYSIS 
8.1. 
Data Management and Quality Assurance Considerations  
This study will employ eCRFs.  The site will be trained on specific forms and procedures for source 
documentation and maintenance of an audit trail of the data that is entered on the eCRF prior to study 
initiation. 
Study personnel at each site will enter data from source documents corresponding to a subject’s visit into 
the protocol-specific eCRF when the information corresponding to that visit is available.  Subjects will 
not be identified by name in the study database or on any study documents to be collected by the Sponsor 
(or designee), but will be identified by subject number (6 digits: the first 3 for the institution and the last 
3 for the subject). 
The Investigators will prepare and maintain adequate and accurate source documents designed to record 
all observations and other pertinent data for each subject treated with the study drug. 
If a correction is required for an eCRF, the time and date will be recorded by the person updating eCRF 
data to create an audit trail.  The Investigator is responsible for all information collected on subjects 
enrolled in this study.  All data collected during the course of this study must be reviewed and verified for 
completeness and accuracy by the Investigator.  
Queries will be issued for any inconsistencies, omissions, and discrepancies and will be resolved by the 
appropriate parties.  
Database lock will occur once quality assurance procedures have been completed. 
The statistical analysis of these data will be performed by the Sponsor or designee.  All AEs will be coded 
using the latest version of the Medical Dictionary for Regulated Activities (MedDRA).  Concomitant 
medications will be coded using the latest version of the World Health Organization Drug Dictionary.  
All procedures for the handling and analysis of data will be conducted using good computing practices 
meeting FDA, European Medicines Agency, and ICH guidelines for the handling and analysis of data for 
clinical studies.  Data management details will be outlined in a separate data management plan. 
8.2. 
Sample Size 
Up to 76 subjects per treatment arm provides 90% power to detect ES of 0.53 and 80% power to detect 
ES of 0.46.  This level of ES is the minimum amount considered clinically relevant treatment effect and is 
less than the effect size seen in the Phase 2a studies; therefore, provides a statistical buffer to achieve a 
positive outcome, if the magnitude of treatment effect by chance is lower in the present study. 
8.3. 
Analysis Sets 
The safety analysis set will include any subject who receives at least 1 dose of study drug. 
The efficacy analysis set will include any subject who receives at least 1 dose of study drug and has at 
least 1 post-dose HVLT-R assessment.

8.4. 
Pharmacokinetics (PK) 
Trough and maximum concentrations (CTrough and Cmax, respectively) will be evaluated on Day 21 (i.e.; at 
steady-state) for each subject and descriptive statistics for the neflamapimod treatment group will be 
presented.  In addition area under the time concentration curve (AUC) will be derived utilizing population 
PK methods utilizing drug concentration data from Day 21 as well the sparse sampling on Days 42 and 
84.  CTrough, Cmax and AUC will be correlated to CYP2C19 genotype status.  In addition, a PK/PD model 
for neflamapimod and effects on HVLT-R, WMS, CDR-SB, and/or CSF biomarkers will be developed 
post hoc based on the available data. 
8.5. 
Efficacy 
8.5.1. 
Primary Efficacy Variables 
The primary efficacy variable is: 
• 
Combined change in z-scores of total recall and delayed recall on the HVLT-R in neflamapimod-
treated subjects compared to placebo-recipients. 
To obtain a single statistic, the total recall and delayed recall scores will be converted to z-scores and the 
combined change in z-scores will be compared for the two treatment groups.  Specific statistical analyses 
for efficacy variables will be identified in a prospective Statistical Analysis Plan. 
8.5.2. 
Secondary Efficacy Variables  
The secondary efficacy variables are: 
• 
Change from Baseline to Week 24 in recall and recognition of the WMS, CDR-SB, 
MMSE, and CSF biomarkers (total tau, p-tauR181
R, AβR1-40
R, AβR1-42
R, neurogranin, 
neurofilament light chains) comparing neflamapimod-treated subjects with placebo-
recipients. 
8.6. 
Safety 
The incidence of treatment-emergent AE and SAEs the causal relationship between an AE/SAE and the 
Study Drug and severity will be tabulated by treatment (dose) group. 
Individual clinically-significant changes in clinical laboratory and ECG parameters will be listed along 
with median and mean and standard deviation by treatment group.   
8.7. 
Interim Analysis 
No interim analysis is planned.  Only pharmacokinetic data will be monitored by an independent clinical 
pharmacologist on an every 3-month basis without any reference to other study data or subject 
identification, with the exception of baseline demographics (age, weight, race) and CYP2C19 genotype.

Application regulations (21 CFR 312) or local national laws (as applicable) and ICH guidelines for 
Good Clinical Practice.  These guidelines are on file at Worldwide Clinical Trials. 
9.1.2. 
Institutional Review Boards/Independent Ethics Committees 
Conduct of the study must be approved by an appropriately constituted IRB or IEC.  Approval is required 
for the study protocol, investigational drug brochure, protocol amendments, ICFs, subject information 
sheets, and advertising materials.  No investigational product will be shipped to a site until written 
IRB/IEC authorization has been received by the Sponsor or its designee. 
9.1.3. 
Informed Consent 
For each study subject, a written ICF will be obtained before any protocol-related activities.  As part of 
this procedure, the Investigator or a designated representative must explain orally and in writing the 
nature, duration, and purpose of the study, and the action of the investigational product in such a manner 
that the subject and (if applicable) appointed guardian are aware of the potential risks, inconveniences, or 
adverse effects that may occur.  Subjects should be informed that they may withdraw from the study at 
any time.  They will receive all information that is required by local regulations and ICH guidelines.  The 
Investigator or a designated representative will provide the Sponsor or its designee with a copy of the 
IRB/IEC-approved ICF before the start of the study. 
9.2. 
Indemnification 
The Sponsor’s indemnification of the Investigator and institution during the conduct of this study is 
addressed in a letter of indemnification provided as a separate document.  Other indemnification or 
insurance will be provided as necessary under local regulations. 
9.3. 
Discontinuation of the Study by the Sponsor 
The planned study period is approximately 2 years, until the last visit of the last subject (including the 
follow-up visit).  The planned subject participation is approximately 30 weeks, including 24 weeks of 
treatment.  Once the subjects have ended his participation in the study, they will return to their standard of 
care treatment as determined by their physician. 
The Sponsor reserves the right to discontinue the study at this site or at multiple sites for safety or 
administrative reasons at any time.  If the Sponsor or Investigator discovers conditions arising during 
the study that suggest the study should be halted, then this can happen only after appropriate consultation 
between the Sponsor and Investigator.  Conditions that may warrant study termination include, but are not 
limited to: 
• 
The discovery of any unexpected, significant, or unacceptable risk to the subjects enrolled in the 
study. 
• 
Failure of the Investigator to enter subjects at an acceptable rate.

• 
Unsatisfactory subject enrollment with respect to quality and/or quantity or data recording is 
inaccurate and/or incomplete on a chronic basis. 
• 
Insufficient adherence to the protocol requirements. 
• 
A decision on the part of the Sponsor to suspend or discontinue development of study drug. 
Should the study be terminated and/or the site closed for whatever reason, all documentation and 
investigational product pertaining to the study must be returned to the Sponsor or its designee. 
9.4. 
Study Documentation 
By signing a copy of Form Food and Drug Administration (FDA) 1572 or other country-specific 
regulatory forms, the Investigator acknowledges that he/she has received a copy of the investigator’s 
brochure on neflamapimod and assures the Sponsor that he/she will comply with the protocol and the 
provisions stated in Form FDA 1572 and other country-specific forms.  No changes in this protocol can 
be made without the Sponsor’s written approval. 
9.5. 
Study Monitoring and Auditing  
This study will be monitored for quality assurance at all stages of its development by the clinical research 
personnel employed by the Sponsor or its designee.  Monitoring will include personal visits and telephone 
communication to assure that the investigation is conducted according to the protocol, standard operating 
procedures, Guidelines of Good Clinical Practice, and applicable regulatory requirements.  Quality 
control procedures will be applied to each stage of data handling to ensure that all data are reliable and 
have been processed correctly.  On-site review of eCRFs will include a review of forms for completeness 
and clarity, and consistency with source documents available for each subject.   
9.6. 
Use of Study Findings  
By signing the study protocol, the Investigator agrees to the use of results of the study for the purposes of 
national and international registration.  If necessary, the authorities will be notified of the Investigator’s 
name, address, qualifications, and extent of involvement.  Reports covering clinical and biometric aspects 
of the study will be prepared by the Sponsor or its designee. 
9.7. 
Publications 
The clinical study will be registered at 38Twww.clinicaltrials.gov38T and 38Twww.clinicaltrialsregister.eu38T.  The 
preparation and submittal for publication of manuscripts containing the study results shall be in 
accordance with a process determined by mutual written agreement among the study Sponsor and 
participating institutions.  The publication or presentation of any study results shall comply with all 
applicable privacy laws.  
9.8. 
Recording, Access and Retention of Source Data

All study documents (subject files, signed ICFs, Study File Notebook, etc.) must be kept secured for a 
period of two years following marketing of the investigational product.  There may be other circumstances 
for which the Sponsor is required to maintain study records and, therefore, the Sponsor should be contacted 
prior to removing study records for any reason. 
9.9. 
Protocol Violations 
A protocol violation occurs when the subject, Investigator, or Sponsor fails to adhere to significant 
protocol requirements affecting the inclusion, exclusion, subject safety, and primary endpoint criteria.  
Protocol violations for this study include, but are not limited to, the following: 
• 
Failure to meet inclusion/exclusion criteria 
• 
Use of a prohibited concomitant medication 
Failure to comply with Good Clinical Practice guidelines will also result in a protocol violation.  The 
Sponsor will determine if a protocol violation will result in withdrawal of a subject. 
When a protocol violation occurs, it will be discussed with the Investigator and a Protocol Violation Form 
detailing the violation will be generated.  This form will be signed by a Sponsor representative and the 
Investigator.  A copy of the form will be filed in the site’s regulatory binder and in the Sponsor’s files.

INTRODUCTION 
This document details the planned statistical analyses for the EIP Pharma, LLC, protocol “EIP-
VX17-745-304” study titled “A Double-Blind, Placebo-Controlled Proof-of-Concept Study of a 
Selective p38 MAP Kinase Alpha Inhibitor, Neflamapimod, Administered for 24 Weeks in 
Subjects with Mild Alzheimer’s Disease”. 
The proposed analyses are based on the contents of the final version 3.0 of the protocol (dated27-
AUG-2018). 
This is a Phase 2, multicenter, randomized, double-blind, placebo-controlled, proof-of-concept 
study of neflamapimod 40 mg or matching placebo administered twice daily for 24 weeks in 
subjects aged 55 to 85 years with CSF biomarker-confirmed AD; with CDR-Global score of 0.5 
or 1.0, with CDR memory subscore of at least 0.5, and MMSE scores between 20 and 28, 
inclusive.   
All screening assessments should be conducted within 42 days of Day 1 (first dose of study 
drug). Once eligibility is confirmed and before the first dose of study drug, subjects are randomly 
assigned (1:1 basis) to receive placebo or neflamapimod treatment. Randomization is stratified 
by 1) background AD-specific therapy (cholinesterase inhibitor or memantine versus no 
cholinesterase inhibitor or memantine); and 2) CDR 0.5 versus 1.0. Dosing will start on Day 1 
following completion of all Baseline procedures.  
Subjects will return to the clinic on Days 21, 42, 84, 126, and 168. 
A Follow-up Visit will be conducted 14 (±3) days following the last dose of study drug. 
Trough and maximum concentrations for PK analysis will be collected for each patient and 
summarized.   An integrated population PK analysis including other study PK parameters will be 
completed and reported on outside of the standard reporting.

STUDY OBJECTIVES 
Primary Objective 
• To evaluate the effect of administration of neflamapimod (VX-745) for 24-weeks on 
immediate and delayed recall aspects of episodic memory, as assessed by the Hopkins 
Verbal Learning Test – Revised (HVLT-R) in subjects with mild Alzheimer’s disease 
(AD).

• To evaluate effects of neflamapimod on immediate and delayed recall of Logical 
Memory (LM), Verbal Paired Associates (VPA) and Visual Reproduction (VR) 
components of the Wechsler Memory Scale® (WMS). 
• To evaluate effects of neflamapimod on the Clinical Dementia Rating Scale-Sum of 
Boxes (CDR-SB) and (Mini-Mental State Examination) MMSE. 
• To evaluate the effects of neflamapimod on AD-related cerebrospinal fluid (CSF) 
biomarkers (total tau, phospho-tau, amyloid-beta peptides, neurogranin,  and 
neurofilament light chain).

ENDPOINTS 
3.1 Primary Endpoint 
The primary efficacy variable is:  
• Combined change in z-scores of total recall and delayed recall on the HVLT-R in 
neflamapimod-treated subjects compared to placebo-recipients at Week 24. 
 
The detailed calculation of combined change in z-scores is described in section 6.2.12. 
3.2 Secondary Endpoints 
The secondary efficacy variables at Week 24 and follow-up when applicable are: 
• Change in WMS immediate and delayed recall composites in neflamapimod-treated 
subjects compared to placebo-recipients. 
• Change in CDR-SB in neflamapimod-treated subjects compared to placebo-recipients. 
• Change in MMSE in neflamapimod-treated subjects compared to placebo-recipients 
• Change in CSF biomarkers [total tau (T-tau), P-tau181, Aβ1-40, Aβ1-42, neurogranin, 
neurofilament light chain] in neflamapimod-treated subjects compared to placebo-
recipients at the end of treatment. 
4 SAMPLE SIZE 
Up to 76 subjects per treatment arm (152 total) provides 90% power to detect ES of 0.53 and 
80% power to detect ES of 0.46. This level of ES is the minimum treatment effect amount 
considered clinically relevant and is less than the effect size seen in the Phase 2a studies.

Randomization was stratified by 1) background AD-specific therapy (cholinesterase inhibitor or 
memantine versus no cholinesterase inhibitor or memantine); and 2) CDR-Global Score of 0.5 
versus 1.0.  
Eligible subjects were randomized 1:1 to two treatment arms: Neflamapimod 40mg or placebo 
utilizing a central Interactive Web Response System (IWRS). 
6 PLANNED ANALYSES 
No statistical analysis plan (SAP) prepared in advance of the data can be absolutely definitive 
and the final clinical study report (CSR) may contain additional tables or statistical tests if 
warranted by the data obtained.  The justification for any such additional analyses will be fully 
documented in the final CSR. 
6.1 Analysis Populations 
6.1.1 
Safety Population 
The Safety Population is defined as all randomized subjects who receive at least one dose of 
study drug (neflamapimod or placebo).  
6.1.2 
Evaluable Efficacy Population 
The Efficacy Population used for efficacy analyses, consistent with the intent-to-treat (ITT) 
principles includes all subjects who received at least one dose of study drug and had at least one 
post-dose efficacy assessment. 
6.1.3 
Per-Protocol Population 
The Per-Protocol Population (PP) will be a subset of the Efficacy Population.   
All protocol deviations will be assessed and documented on a case-by-case basis before the 
database lock, and deviations considered to have a significant impact on the efficacy results will 
lead to the relevant subject being excluded from the PP.  Before database lock, potential subject 
exclusions from the PP will be reviewed by the Sponsor and documented in a subject 
evaluability document (WCT-TP-ST-016).  
6.1.4 
Pharmacokinetics (PK) Population 
The Pharmakinetics (PK) Population includes all randomized subjects who received at least 
one dose of study drug in neflamapimod treatment group and had at least one post-dose PK data 
assessment.

6.2 
Derived Data and Clinical Assessments 
This section describes the derivations required for statistical analysis. Unless otherwise stated, 
variables derived in the source data will not be re-calculated. 
6.2.1 
Screening 
For each variable where a subject is re-screened, his/her latest non-missing value from the 
original or re-screening assessment will be taken for tabulation purposes. 
6.2.2 
Baseline and Change from Baseline 
Baseline is defined as the last non-missing value (either scheduled, unscheduled or repeat) before 
the subject receives first dose of study drug (Day 1). Visit 3 (Day 1) date is definded as the date 
of the first dose.  
Baseline score of MMSE for each subject is calculated using the average of Screen and Day 1 
measurements. 
Change from baseline CHG=AVAL-BASE where AVAL is the post-baseline value, BASE is the 
baseline value.  
Baseline z-score will be used as a covariate in the MMRM and ANCOVA analysis. It will be 
calculated as below: 
For baseline total recall, a z-score for each subject is defined by z=(x-m)/s where x is the 
subject's total recall at baseline, and m and s are the overall mean and overall standard deviation 
of total recall at baseline across all subjects. Similarly, a baseline z-score for each subject for 
delayed recall can be calculated. 
A composite baseline z-score for each subject is calculated using equal weighting in the 
following way:  
Z=0.5*z-score for total recall at baseline + 0.5*z-score for delayed recall at baseline. 
The calculation method can be referenced to Section 6.2.12. 
6.2.3 
Duration/Study Day/Time  
Study day will be calculated as the number of days from first dose of study drug.  
• date of event – date of first dose of study drug + 1, for events on or after first dose  
• date of event – date of first dose of study drug, for events before first dose.

• Duration (e.g., event duration/medication usage) = stop date-start date +1. 
6.2.4 
Conventions for Missing and Partial Dates 
All rules explained below for partial/missing dates will be followed unless contradicted by any 
other data recorded on the electronic Case Report Form (eCRF). 
All dates presented in the individual subject listings will be as recorded on the eCRF (i.e., not 
completed as per the below rules). 
6.2.5 
Missing/Partial Start/Stop Date of Adverse Events and Concomitant Medications 
Missing and partial start and stop date will be imputed for analysis purposes as follows: 
Partial or missing stop date will be imputed as follows: 
If the stop date is completely missing and the event has resolved or the subject has stopped 
taking the concomitant medication, the stop date will be imputed as the date of the subject’s last 
clinic visit in the study. 
• If only the year is known, the stop date will be imputed as “31-Dec” of that year or as the 
date of the subject’s last clinic visit in the study if in the same year. 
• If the month and year are known, the stop date will be imputed as the last day of that 
month unless the stop date corresponds to the same month as the subject’s last clinic visit 
in which case the date of subject’s last clinic visit in the study will be used instead. 
 
Missing start date will be imputed as follows: 
• If the stop date occurs on or after the start of study drug or the event/concomitant 
medication is ongoing, the start date will be imputed as the date of the first dose of study 
drug.  
• If the stop date occurs before the start of study drug, the start date of the 
event/concomitant medication will be imputed as the subject’s screening date or the stop 
date of the event/concomitant medication whichever the earlier. 
 
Partial start date (year present, but month and day missing) 
• If the stop date occurs on or after the start of study drug or the event/concomitant 
medication is ongoing, and the year is the same as the year of first dosing the start date 
will be imputed as “01-Jan” of the same year or the date of the first dose of study drug

whichever is latest. If the year is different from the year of first dosing “01-Jan” will be 
used. 
• If the stop date occurs before the start of study drug, the start date of the 
event/concomitant medication will be imputed as the “01-Jan” of the same year. 
 
Partial start date (month and year present, but day missing) 
• If the stop date occurs on or after the start of study drug or the event/concomitant 
medication is ongoing, the start date will be imputed as the first day of the same month 
and year unless this partial start date is in same month as the first dose of study drug in 
which case the date of first dose of study drug will be used.  
• If the stop date occurs before the start of study drug, the start date will be imputed as the 
first day of the month and year of the partial stop date. 
 
Missing start/stop time of adverse events: 
• If the start time of the adverse event (AE) is missing, it will imputed only in the case 
where the start date of the AE corresponds to the date of the first dose of study drug. The 
time will be imputed as the same time as the first dose of study drug. In all other cases the 
time will not be imputed. 
• If the stop time of the adverse event is missing, it will be imputed as 23:59 for stop time. 
6.2.6 
Missing Last Dates of Study Drug Dosing 
If the date of last dose of study drug is completely missing then the date of last dose of study 
drug will be taken for analysis purposes as the date when the subject would have run out of study 
drug assuming full compliance from the date the study drug was last dispensed or the date of 
subject’s last clinic visit in the study or early withdrawal or death whichever the earlier 
If only the month and year of the last dose was recorded, then the date of last dosing will be 
taken for analysis purposes as the date the subject would have run out of study drug assuming 
full compliance from the date the study drug was last dispensed, the last day of the month of the 
recorded last dose or the date of subject’s last clinic visit in the study or early withdrawal or 
death whichever the earlier.

If the month and year are present but the day is missing, the diagnosis date will be set to the first 
day of the relevant month. If only the year is recorded the diagnosis date will be set as “01-Jan” 
for that year.   
6.2.8 
Exposure to Study Drug  
Exposure to study drug will be calculated as follows from the date of last dosing minus the first 
day of dosing + 1. The exposure calculation will not take into account breaks in therapy. 
6.2.9 
Inexact Values 
In the case where a variable is recorded as “> x”, “≥ x”, “< x” or “≤ x”, a value of x will be taken 
for analysis purposes, Where a range of values is quoted the midpoint of the range will be taken.  
6.2.10 
Electrocardiogram Data 
For 12-lead ECG data recorded on continuous scales, if more than one value is recorded at a 
visit, the mean value rounded to the integer will be presented. For overall interpretation if more 
than one value is recorded, the most severe (worst case) of the respective readings will be taken.  
6.2.11 
HVLT-R and WMS 
The HVLT-R is a verbal learning and memory test, with 6 validated alternate forms. Each form 
contains 12 nouns, 4 words each from 1 of 3 semantic categories (e.g., precious gems, articles of 
clothing, vegetables), to be learned, and repeated back to the evaluator over the course of 3 
learning trials. Approximately 20–25 minutes later, a delayed recall trial and a recognition trial 
are completed. The delayed recall requires free recall of any words remembered. The recognition 
trial is composed of 24 words, including the 12 target words and 12 false-positives, 6 
semantically related, and 6 semantically unrelated. The 3 learning trials are combined to 
calculate a total recall score; the delayed recall trial creates the delayed recall score.  
For WMS, LM I & II & II-(Recognition), VPA I & II & II-(Recognition), and VR I & II & II-
(Recognition) will be applied. 
There are following tests in WMS: Logical Memory test, in which subject is read a story; 
Verbal-Paired Associates, in which subject is given pairs of words and asked remember which 
words go together; and Visual Reproduction, in which subject is given drawings of specific 
shapes.  Subjects were then asked to recall the information within each test both in an immediate 
(WMS-Immediate Recall composite) and delayed (WMS-Delayed Recall composite) basis.   
The WMS immediate recall composite score is the total of all of the immediate recall tasks 
combined and the delayed recall composite is the delayed recall tasks combined.

The HVLT-R and WMS tests must be performed sequentially within the day; with the HVLT-R 
to be conducted first and completed (including delayed recall component), prior to commencing 
WMS test. 
6.2.12 
Z-Score 
For post-baseline total recall, a z-score for each subject at a specific visit is defined by z=(x-m)/s 
where x is the subject's total recall at that visit, and m and s are the overall mean and overall 
standard deviation of total recall from baseline visit across all subjects. Similarly, a z-score for 
each subject for delayed recall can be calculated.  
A post-baseline composite z-score for each subject on the HVLT-R at that visit is calculated 
using equal weighting in the following way: Z = 0.5*z-score for total recall + 0.5*z-score for 
delayed recall. 
Combined change in z-scores = Z(post-baseline) – Z(baseline). 
Z(baseline) is described in Section 6.2.2. 
6.2.13 
CDR 
The CDR (Hughes, 1982) is a semi-structured interview resulting in a semi-quantitative scoring 
of cognitive impairment in milder and more progressed forms of dementia. The overall CDR 
rating, along with the memory box score, will be used to determine a subject’s eligibility for 
inclusion.  The CDR score - SB will also be used in calculating treatment group means for 
change from baseline calculation.  Standardized CDR will be conducted by the Investigator or 
designee. 
CDR score (sum of boxes) is the sum of each domain score. 
6.2.14 
MMSE 
The MMSE (Folstein et al, 1975) consists of 11 tests of orientation, memory (recent and 
immediate), concentration, language, and praxis. Scores range from 0 to 30, with lower scores 
indicating greater cognitive impairment. It is based on the performance of the subject and takes 
approximately 5 to 10 minutes to administer. Standardized MMSE (Version 2.0) will be 
conducted by the Investigator or designee.  The MMSE score is used for eligibility as well as 
calculating treatment group means for change from baseline.

and visit will be reported for all efficacy endpoints. All statistical tests will be performed using a 
two-tailed 5% overall significance level, unless otherwise stated.  All comparisons between 
treatments will be reported with 95% confidence intervals for the difference. 
There will be no imputation of missing efficacy data. 
6.10.1 
Primary Endpoint 
The primary efficacy endpoint is: 
Combined change in z-scores of total recall and delayed recall on the HVLT-R in neflamapimod- 
treated subjects compared to placebo-recipients at Week 24.  
Neflamapimod 40 mg group will be compared to the placebo group.  
The hypothesis test is as follows: 
Ho: µneflamapimod = µplacebo 
H1: µneflamapimod ≠ µplacebo 
The null hypothesis will be rejected at a significance level of α (two-sided) = 0.05.  There will be 
no p-value adjustment for multiplicity.  
6.10.2 
Primary Efficacy Analysis 
The primary endpoint will be analyzed using Mixed Model for Repeated Measures (MMRM) 
with fixed effects for treatment, background AD-specific therapy (cholinesterase inhibitor or 
memantine versus no cholinesterase inhibitor or memantine), CDR-Global Score of 0.5 versus 
1.0, scheduled visit (nominal) and scheduled visit by treatment interaction, random effect for 
subject and baseline z-score as a covariate. Least-square means (LSM) and 2-sided 95% 
confidence intervals (CI) will be provided for treatment group differences and estimated 
endpoint values by visit.  
The normally-distributed assumption for the combined change in z-scores of total recall and 
delayed recall on the HVLT-R will be examined (at 0.05 alpha level). In case the assumption is 
violated, rank transformed data will be applied to the MMRM model. Ranks will be determined 
separately within each time point, based on observed data only. 
In addition, Scale plot will be provided for combined change in z-scores of total recall and 
delayed recall on the HVLT-R at each post-baseline visit by treatment group.

• Repeat the primary efficacy analysis with the Per Protocol Population 
• Use an analysis of covariance (ANCOVA) with treatment group, background AD-
specific therapy, CDR-Global Score as main effects and the baseline z-score as the 
covariate to compare Z-scores of total recall and delayed recall on the HVLT-R at Week 
24 in the neflamapimod and placebo groups 
The results of the ANCOVA will be summarized using the treatment groups’ least square means, 
the difference between the treatment groups’ least square means, the 95% confidence interval for 
the treatment group difference and the p-value. 
6.10.4 
Secondary Analyses 
The secondary efficacy endpoints at Week 24 and follow-up when applicable are: 
• Change in WMS immediate and delayed recall composites in neflamapimod-treated 
subjects compared to placebo-recipients. 
• Change in CDR-SB in neflamapimod-treated subjects compared to placebo-recipients. 
• Change in MMSE in neflamapimod-treated subjects compared to placebo-recipients. 
• Change in CSF biomarkers (T-tau, P-tau181, Aβ1-40, Aβ1-42, neurogranin, neurofilament 
light chain) in neflamapimod-treated subjects compared to placebo-recipients at the end 
of treatment. 
The same method used for the primary efficacy analysis will be applied for the analyses of the 
change in WMS and change in CDR-SB.  
Changes in MMSE and CSF biomarkers will be compared using an analysis of covariance 
(ANCOVA) with treatment group, background AD-specific therapy, CDR-Global Score as main 
effects and the baseline assessment as the covariate.  The results of the ANCOVA will be 
summarized using the treatment groups’ least square means, the difference between the treatment 
groups’ least square means, the 95% confidence interval for the treatment group difference and 
the p-value. Scale Plots of Mini-Mental State Examination (MMSE) Score by Visit and by 
Treatment; and Baseline and Change from Baseline to Day 84 MMSE Score.

Exploratory Analyses 
Additional exploratory analyses may be performed to further study the effects of treatment as 
data warranted.  Numerical exploratory endpoints will be analyzed using analysis of covariance, 
t-tests, or Wilcoxon sign rank test. Analysis of categorical exploratory endpoints will be 
performed using chi-square test.  Exploratory endpoints include

Subgroup Analyses  
The results for the primary and secondary endpoints will be further analyzed on the patients 
with a background AD-specific therapy, and those not on a background AD-specific therapy as 
well as for disease severity (patients who have a CDR score of 0.5 versus 1.0).  Another 
subgroup analysis will be performed base on patient baseline body weight (<80 kg and ≥80kg).  
6.10.7 
Multiplicity 
All secondary endpoints and the supportive analyses will be considered as descriptive evidence 
of efficacy and will be analyzed without any procedures to account for multiple comparisons. 
6.11 Pharmacokinetic Analysis 
Neflamapimod concentration values will be reported for the PK population.  All PK data 
collected will be included in data listings sorted by treatment, patient and time point, as 
appropriate.   
Individual values and descriptive statistics for the plasma concentrations of neflamapimod will 
be summarized by neflamapimod treatment and by visit. Boxplots of the distributions of 
neflamapimod concentrations by visit will be used to present graphical summaries of 
neflamapimod concentration data. 
Trough and maximum concentrations (CTrough and Cmax, respectively) will be obtained on Day 21 
(i.e., at steady-state) for each subject by observation and descriptive statistics for the 
neflamapimod treatment group will be presented.   
In addition, the effect of CYP2C19 genotype status on PK parameters will be investigated.

Analyses of CSF biomarkers (T-tau, P-tau181, Aβ1-40, Aβ1-42, neurogranin, neurofilament light 
chain) will use observational Trough and maximum concentrations (CTrough and Cmax, 
respectively) on Day 21 as exposure parameters in the initial PK-PD analysis.  For numerical PD 
endpoints, both absolute and percent change from pre-treatment assessments will be performed, 
as appropriate. Number and percent will be provided for categorical PD parameters (e.g. 
CYP2C19). Overall, summary statistics and for each treatment group for biomarkers will be 
presented and a by-subject listing of plasma biomarker results will be provided as an appendix. 
Additional PK-PD exploratory analyses may be performed to further study the effects of the 
treatment via PK parameters (i.e. CTrough and Cmax) on HVLT-R, WMS, CDR, and/or CSF 
biomarkers, as warranted by data. Nominal CTrough and Cmax will be summarized based on 
concentration values by nominal hour at Day 21 (i.e. 2.5 hour for Cmax and 0 hour for CTrough). 
For many endpoints, both absolute and percent change from pre-treatment assessments will be 
performed.  All data collected and captured in the CRF will be included in data listings sorted by 
treatment, patient and time point, as appropriate.   
6.13 Safety Analyses 
The safety analyses will be presented by the treatment received for the Safety Population. 
6.13.1 
Adverse Events 
A treatment emergent adverse event (TEAE) is defined as:  
• Any AE with an onset on or after the first dose of study drug and through 30 days after 
the last dose of study drug in the double blind treatment period.  
• Any pre-existing AE that has worsened in severity on or after the first dose of study drug 
and through 30 days after the last dose of study drug in the double blind treatment period. 
A treatment-related AE is defined as an AE as being possibly related to the study drug. If an AE 
has a missing relationship, it is assumed to be related to the study drug for analysis purposes. 
Maximum severity will be assumed for an AE with missing severity.  
 
The following tables will be presented for AEs:

Additionally, the number and percentage of subjects in each treatment group who meet any of 
the following criteria for QT or QTcF will be tabulated by treatment group and visit. 
• Maximum value >450 to 480 msec  
• Maximum value >480 to 500 msec  
• Maximum value >500 msec 
• Maximum increase from baseline >30 to 60 msec 
• Maximum increase from baseline >60 msec 
Shift tables in relation to the overall interpretation (Normal, Abnormal NCS, and Abnormal CS) 
from baseline to each follow-up visit will be presented.  
Box plots for ECG data will be provided for changes from baseline by visit and maximal change. 
6.13.5 
Physical Examination 
The body systems within the physical examination data will be summarized by treatment group 
and visit (Abnormal NCS and Abnormal CS). Changes from baseline will also be tabulated. 
Details of clinically significant findings will be listed.  
Descriptive statistics for observed values and changes from baseline in weight will be presented 
by treatment group and visit.   
7 INTERIM ANALYSIS 
No formal interim analyses are planned.  
8 DATA SAFETY MONITORING BOARD ANALYSIS 
No data safety monitoring board (DSMB) analyses are planned.
