Brief summary:
MW01-2-151SRM (=MW151), a small molecule, is being developed for the treatment of cognitive disorders. The development program is based on nonclinical evidence that MW151 improves neurocognitive outcomes in animal models of radiation-induced cognitive impairment, Alzheimer's disease, and other central nervous system (CNS) disorders.

The present study will provide safety and pharmacokinetic (PK) information on single ascending doses to support decisions for continued clinical development.

Detailed description:
The primary objective of this trial is to assess the safety and tolerability of single ascending doses of MW151 when administered orally to healthy adults.

Subjects will be screened prior to inpatient admission. Subjects will be admitted to the inpatient clinic on the day prior to dosing (Day -1) and will remain in the unit until discharge on Day 3. A follow-up visit will be done on Day 7. A single dose of study drug or placebo will be administered on Day 1. Healthy adult female subjects will be randomly assigned to one of 5 dose cohorts (8 subjects each). Each subject will receive a single dose of MW151 (10-160mg) or placebo under fasted conditions.

Following a review of safety and tolerability data for the first 24 hours of dosing in each cohort (including reported adverse events (AEs), physical examination findings, clinical laboratory results, vital signs, and electrocardiograms (ECGs), the remaining 6 subjects will be randomized in a 5:1 ratio. Dosing of the remaining subjects in a cohort may proceed after review of sentinel subject safety data collected during the first 24 hours of dosing and determination that no stopping rules are met. The remaining subjects in each cohort will be dosed sequentially, not simultaneously.

Arms: arm 1: Participants will receive placebo. arm 2: Participants will receive 10 mg of MW151. arm 3: Participants will receive 20mg of MW151. arm 4: Participants will receive 40mg of MW151. arm 5: Participants will receive 80mg of MW151. arm 6: Participants will receive 160mg of MW151.
Interventions: intervention 1: Placebo intervention 2: MW151, 10mg intervention 3: MW151, 20mg intervention 4: MW151, 40mg intervention 5: MW151, 80mg intervention 6: MW151, 160mg
Intervention descriptions: intervention 1: Matched placebo administered orally intervention 2: 10 mg MW151, 1 x 10mg capsule administered orally intervention 3: 20 mg MW151, 1 x 20mg capsule administered orally intervention 4: 40 mg MW151, 2 x 20mg capsule administered orally intervention 5: 80 mg MW151, 1 x 80mg capsule administered orally intervention 6: 160 mg MW151, 2 x 80mg capsule administered orally

Interventions and 
Duration 
Subjects will be screened in the 28 days prior to inpatient admission. 
Subjects will be admitted to the inpatient clinic on the day prior to 
dosing (Day -1) and will remain in the unit until discharge on Day 3. A 
follow-up visit will be done on Day 7. A single dose of study drug or 
placebo will be administered on Day 1. 
40 healthy adult subjects will be assigned to one of 5 dose cohorts (8 
subjects each). The starting dose (10 mg) cohort 1 will include male 
and female subjects; cohorts 2 – 5 will include only female subjects. 
Within each cohort, 8 subjects will be randomized to receive MW151 
or placebo in the ratio 6:2. According to the dosing scheme each 
subject will receive a single dose of MW151 or placebo under fasted 
conditions. 
1. Starting dose: Dose1 (10 mg) 
2. Dose2 (20 mg) 
3. Dose3 (40 mg) 
4. Dose4 (80 mg) 
5. Dose5 (160 mg) 
As a safety consideration two sentinel subjects in each cohort will be 
administered MW151 or placebo in a 1:1 ratio.

Following review of sentinel safety and tolerability data for the first 24 
hours of dosing in each cohort (including reported adverse events 
[AEs], physical examination findings, clinical laboratory results, vital 
signs, and electrocardiograms [ECGs]), the remaining 6 subjects will 
be randomized in a 5:1 ratio. Dosing of the remaining subjects in a 
cohort may proceed after review of sentinel subject safety data 
collected during the first 24 hours of dosing and determination that 
no stopping rules are met. The remaining subjects in each cohort will 
be dosed sequentially, not simultaneously. 
After the completion of each cohort (Cohorts 1-5), the DSMB will 
review all available safety data before the dosing of the sentinel 
subjects of the next cohort. 
Patients will receive standardized meals during the Inpatient Phase. 
Data from Cohorts 1-5 will be reviewed in a blinded manner, unless 
the findings suggest the triggering of a stopping rule, in which case 
the data for the subjects in question may be unblinded (e.g, if a drug 
related serious AE [SAE] occurs, identifying whether the subject 
received MW151 or placebo to determine whether the stopping rule 
should be triggered). 
If the data raises questions about safety, the subsequent dose for 
cohorts may be modified by one of the following: 
1) repeating the previous dose, 
2) administering an intermediate dose, or 
3) terminating dose escalation.

All subjects who receive any study treatment will be included in the 
safety analysis grouped by treatment received. Statistical analysis of 
safety data will be descriptive. PK analysis will include, but not be

Six actively treated subjects per cohort of 8 (n = 6 MW151, n = 2 
placebo) are considered sufficient to provide information on the PK 
profile and an estimation of safety and tolerability of MW151. 
Although the sample size is not based on a statistical power

2 BACKGROUND 
2.1 
Rationale 
Rationale for Study and Disease Indication: Cognitive decline and deterioration of long-term 
cognitive performance are major side effects of CNS cancer treatment. Brain metastases are the 
most common CNS malignancies and a common cause of morbidity and mortality in up to 40% of all 
cancer patients with systemic disease, affecting over 170,000 patients in the US annually (Khuntia et 
al., 2006; Langer & Mehta, 2005). The main treatment modalities for brain metastases include 
surgery, whole brain radiation therapy (WBRT) and/or stereotactic radiosurgery. Despite the 
advantages of WBRT for disease control, cognitive impairment can be seen as early as 3 to 6 months 
after WBRT, and affects approximately 80-90% of patients, with memory and executive function 
being the major cognitive domains affected (Greene-Schloesser & Robbins, 2012; Khuntia et al., 
2006; Langer & Mehta, 2005). Although the mechanisms underlying the treatment-induced cognitive 
decline are not completely understood, proinflammatory cytokine overproduction by activated glia 
after radiation therapy has been consistently implicated in the pathogenesis of WBRT-induced 
cognitive impairment (Greene- Schloesser & Robbins, 2012; Lumniczky et al., 2017; Warrington et 
al., 2013). Therefore, therapies that reduce the radiation-induced inflammatory response and 
subsequent neuronal damage should be explored as a potential adjunctive strategy for reducing 
WBRT-induced cognitive decline in patients with brain metastases. 
More broadly, neuroinflammation, or dysregulated inflammation in the brain, is generally accepted as 
a contributor to disease susceptibility and pathophysiology progression in a wide range of 
neurodegenerative disorders associated with cognitive impairment such as Alzheimer’s disease (AD) 
and related dementias, traumatic brain injury (TBI), and seizure disorders (Andreasson et al., 2016; 
Heneka et al., 2015; Heppner et al., 2015; Van Eldik et al., 2007; Van Eldik et al., 2016). A specific 
aspect of neuroinflammation, proinflammatory cytokine overproduction from abnormally activated 
glia, is associated with disease progression and is a druggable process for potential disease 
modification. However, drugs that target this pathological mechanism are severely underrepresented 
in the portfolio of candidates being advanced for CNS disorders (Cummings et al., 2018; Fillit et al., 
2017). 
Our clinical candidate MW01-2-151SRM (=MW151), was developed as part of ongoing attempts to fill 
this clinical void. MW151 is a novel, CNS-penetrant, orally bioavailable, small molecule drug 
candidate that selectively suppresses stressor-induced proinflammatory cytokine overproduction with 
resultant amelioration of synaptic damage and cognitive impairment (Hu et al., 2007). The efficacy 
and pharmacodynamics (PD) of MW151 are evident across a dozen diverse animal studies where 
cytokine overproduction is a contributor to pathophysiology progression. MW151 exhibits efficacy, at 
low doses. It does not bring about immunosuppression or a non-selective anti-inflammatory action. 
There is no evidence of suppression of basal cytokine levels characteristic of homeostasis. Function 
at efficacy doses involves restoration to homeostasis after disease or injury induced increases. 
Overall, nonclinical efficacy findings and safety profile from nonclinical safety studies suggest that 
MW151 holds the potential to be useful clinically in treating multiple CNS disorders with cognitive 
impairment complications. In addition, based on its mechanism of action, MW151 could have 
disease-modifying effects not only in dementias, but also in a number of acute CNS injuries where 
proinflammatory cytokine dysregulation is part of the pathophysiology progression mechanism. 
Finally, MW151 is attractive for development as a stand-alone disease-modifying therapeutic or as 
part of an armamentarium of therapeutic approaches to alter disease progression in cognitive 
disorders.

2.2 
Rationale for Dose Selection 
To calculate the doses of MW151 to use in this FIH trial, we followed the FDA Guidance for 
“Estimating the Maximum Safe Starting Dose in Initial Clinical Trials for Therapeutics in Adult Healthy 
Volunteers.” We based our dose calculations on NOAEL dose levels from two rat 28- day toxicology 
studies, as well as the dose with minimal changes in ECG measurement from the dog cardiovascular 
safety pharmacology study. In one of the rat tox studies the NOAEL was 10 mg/kg in male rats and 
30 mg/kg in female rats. In the other rat toxicology study, the NOAEL was 30 mg/kg in both male and 
female rats. The dog cardiovascular safety pharmacology study revealed only minimal ECG changes 
at 10 mg/kg. Table 1 summarizes NOAELs and exposures from the MW151 non-clinical safety 
program. Based on the human equivalent dose (HED) and AUC, we based our calculations on the 
most conservative value of 10 mg/kg in male rats. For a 60 kg human subject, this corresponds to a 
HED of 96 mg. With a 10-fold safety margin, the planned starting dose for FIH clinical studies of 
MW151 is 10 mg. Therefore, cohort 1 will receive 10 mg, and we plan to double the dose in each 
subsequent cohort (cohort 2: 20 mg, cohort 3: 40 mg, cohort 4: 80 mg, cohort 5: 160 mg). Cohorts 2 
– 5 will consist of female subjects only. These doses may be varied based on the safety review. 
Efficacious doses of MW151 in mouse models range from 0.5 to 5 mg/kg, which would represent 
HED ranging from 0.04 to 0.4 mg/kg (=2.4 – 24 mg in a 60 kg human). Thus, the proposed doses in 
the phase 1a are predicted to be well within the range to provide efficacy in future phase 2 studies.

 Nonclinical Studies Pharmacology: 
The pharmacological mechanism of action of MW151 is to selectively suppress stressor- induced 
proinflammatory cytokine overproduction, with resultant amelioration of synaptic damage and 
cognitive impairment. In in vitro based glial activation assays, treatment with MW151 exhibited 
concentration-dependent suppression of several proinflammatory cytokines typically upregulated by 
microglia in neurodegenerative disorder, such as IL-1β and TNFα. In addition, in multiple animal 
models of CNS diseases, MW151 treatment produced histological and biochemical findings 
consistent with the ability to significantly attenuate glial activation and proinflammatory cytokine 
overproduction. The inhibition of glial proinflammatory response correlated well with attenuation of 
synaptic and behavioral deficits. Importantly, this efficacy is achieved in the absence of any signs of 
general immunosuppression or non-selective anti- inflammatory action, and no suppression of basal 
cytokine levels in normal animals. 
Preclinical Models of Radiation-Induced Impairment: The therapeutic potential of MW151 for 
radiation induced cognitive impairment was studied in adult, male Fisher 344 rats subjected to whole-
brain irradiation (WBI, 10Gy). Twenty-four hours post-WBI, treatment with once daily 5 mg/kg MW151 
i.p. or vehicle control was initiated and continued for 28 days. Proinflammatory activated microglia in 
the dentate gyrus were assayed at 2 and 9 months post-WBI. Cell proliferation and neurogenesis in 
the dentate gyrus were assayed at 2 months post-WBI. Novel object recognition and long-term 
potentiation were assayed at 6 and 9 months post-WBI, respectively. MW151 mitigated radiation-
induced neuroinflammation at both early and late time points post-WBI, selectively mitigated the 
deleterious effects of irradiation on hippocampal neurogenesis, and potently mitigated radiation-
induced deficits of novel object recognition consolidation ↓ restoring performance to sham-control 
levels ↓ and of long-term potentiation induction and maintenance (Jenrow et al., 2013). 
MW151 was also studied in a model of radiation-induced skin injury in C57BL/6 mice, which received 
focal irradiation (30Gy) on the right hind leg, followed by 5 mg/kg i.p. administration of MW151 three 
times per week for 21 days, beginning 3, 7, or 14 days post-irradiation. Infiltrating macrophages were 
persistently increased in irradiated skin and were reduced by MW151 treatment. Irradiated skin also 
exhibited persistent increases in cells expressing inflammatory cytokines, TGF-β, TNF-β and MMP9. 
Relative to radiation alone, MW151 administration initiated on days 7 and 14 dramatically reduced 
expression of these markers in skin from mice that responded to MW151 therapy when assayed at 
60–70 days post-irradiation, with skin injury scores showing improvement starting at Day 28 post-
irradiation (Jenrow et al., 2014). 
Preclinical Models of Other CNS Disorders/Injury: Complementary pharmacological findings in a 
variety of nonclinical models of CNS disease and injury indicate that MW151 can effectively limit 
upregulated glial inflammatory responses and provide neurologic and functional improvements. Table 
2 shows a summary of MW151 efficacy and PD in a variety of preclinical animal models.

Overall, the nonclinical pharmacology data suggest that MW151 can exert a positive influence on 
post-injury neurologic outcomes by blunting the brain's intrinsic inflammatory response to CNS insults 
or disease over a dose range of 0.5 – 10 mg/kg when administered intraperitoneally (i.p.) and 2.5 – 
15 mg/kg when administered orally (p.o.). MW151 can suppress the excessive activation of microglia, 
and their proinflammatory effector responses. The drug is effective at limiting pathophysiological 
sequelae and secondary neuronal injury in CNS-inflammatory disease relevant animal models, 
including rodent models of radiation-induced cognitive impairment. 
MW151 is moderately well, orally absorbed in rat and dog (F%=23-47%) and distributes into the CNS 
with brain-plasma ratios > 1. Plasma protein binding of MW151 is high in rat, dog and human with 
97.2, 93.9 and 97.1%, respectively. 
MW151 appears to be preferentially metabolized by CYP1A2. MW151 has the potential to inhibit 
CYP2C8 (IC50 = 1.6-12 µM) and to induce CYP3A4 at concentrations ≥ 0.4 µM. 
ECG measurements in Beagle dogs revealed increases in QTc prolongation at MW151 doses ≥ 30 
mg/kg. These findings appear to be associated with total peak plasma concentrations that are higher 
than the hERG IC50 value for MW151 (9.21 µM) or > 2,400 ng/mL. At the highest proposed clinical 
dose for the SAD Ph1 Study (160 mg), the corresponding preclinical dose in dog based on BSA 
conversion (4.8 mg/kg) would be associated with plasma Cmax values below 2,400 ng/mL. 
In 28-day repeat dose toxicity studies in rat and dog, the testes and epididymis were identified as the 
principal target organs of toxicity of MW151. Macroscopic, organ weight and microscopic findings in 
testes have been observed in Wistar rats and Beagle dogs. Sprague-Dawley rats did not show the 
same testicular toxicity effects of MW151 as Wistar rats, and instead showed only slight reduction in 
the weight of seminal vesicles at comparable dose levels. Increases in liver function enzymes and 
bilirubin were observed in some studies at the upper part of the evaluated dose spectrum. These 
findings typically were mild in nature or reversible and had no histopathological correlates in any of 
the studies performed. 
MW151 was found to be non-mutagenic in two GLP Ames assays and negative in in vivo 
micronucleus studies in mouse and rat. Two out of the three in vitro mammalian cell assays

suggested a genotoxic potential of MW151. MW151 showed mutagenic or weak clastogenic potential 
in the mouse lymphoma and human lymphocyte mammalian cell genotoxicity assays, respectively, 
but was negative for clastogenicity in a chromosome aberration assay in V79 Chinese hamster cells. 
Given the lack of consistent reproducibility of the genotoxic findings, the presence of two negative in 
vivo micronucleus assays and two negative bacterial reverse mutation assays, and the fact that 
potential genotoxic findings were only observed with non- GMP batches of MW151, the sponsor 
concludes that the potential for genotoxity is low and acceptable in the context of a First-in-Human 
single ascending dose study (Jacobson-Kram & Jacobs, 2005), and that the risk/benefit profile with 
respect to genotoxicity is acceptable for repeat-dosing in the intended patient population undergoing 
treatment for brain tumors. 
Based on the totality of the data, the Wistar rat was considered the most sensitive species/strain in 
the context of the MW151 toxicology program. Therefore, the NOAEL for Wistar male rats (10 
mg/kg/day) in Study No. 465975 following 28-day dosing with MW151 has been selected for the 
estimation of the safe starting dose for FIH clinical studies in healthy volunteers. Based on human 
equivalent dose (HED) conversion and a 10-fold safety factor, a FIH starting dose of 10 mg MW151 
(free base equivalent) is being proposed. 
Previous Human Experience: None. The phase 1a SAD trial will be a first-in-human study of 
MW151.

3 STUDY DESIGN 
Approximately 40 healthy adult subjects, ages 18-50 years, will be dosed in 1 of 5 dosing cohorts of 8 
subjects each (6 MW151, 2 matched placebo). Cohort 1 will consist of males and females; cohorts 2 
– 5 will consist of females only. Each subject will receive 1 oral dose level of MW151. Five different 
doses of MW151 will be evaluated in 5 sequential cohorts. Dosing will start at the lowest dose, then 
escalate in the 2nd cohort, then escalate sequentially in the 3rd, 4th, and 5th cohorts. Plasma samples 
drawn at sequential time points for PK analysis; safety parameters monitored. Subjects will be 
followed in a dedicated inpatient unit at the clinical site, and will receive standardized meals during 
the Inpatient Phase. 
As a safety consideration two sentinel subjects in each cohort will be administered MW151 or 
placebo in a 1:1 ratio. 
Following review of sentinel safety and tolerability data for the first 24 hours of dosing in each cohort 
(including reported adverse events [AEs], physical examination findings, clinical laboratory results, 
vital signs, and electrocardiograms [ECGs]), the remaining 6 subjects will be randomized in a 5:1 
ratio. Dosing of the remaining subjects in a cohort may proceed after review of sentinel subject safety 
data collected during the first 24 hours of dosing and determination that no stopping rules are met. 
The remaining subjects in each cohort will be dosed sequentially, not simultaneously. 
After the completion of each cohort (Cohorts 1-5), the DSMB will review all available safety data 
before the dosing of the sentinel subjects of the next cohort. There will also be an interim PK analysis 
after the completion of Cohort 2. 
Data from Cohorts 1-5 will be reviewed in a blinded manner, unless the findings suggest the 
triggering of a stopping rule, in which case the data for the subjects in question may be unblinded 
(e.g, if a drug related serious AE [SAE] occurs, identifying whether the subject received MW151 or 
placebo to determine whether the stopping rule should be triggered). 
Dosing will start in cohort 1 at 10 mg of MW151, then escalate to a planned dose doubling in each 
subsequent cohort (cohort 2: 20 mg, cohort 3: 40 mg, cohort 4: 80 mg, cohort 5: 160 mg). These 
doses may be varied based on the safety review, but the maximum dose will not exceed 160mg 
without amending the protocol. Should the safety data warrant, dose levels may be reduced or 
additional cohorts added in order to generate a comprehensive understanding of the clinical dose 
range. Should additional cohorts be required above the planned 5 cohorts or doses within the 
planned cohorts changed, a protocol amendment will be submitted to the FDA and the Independent 
Ethics Committee for approval before implementation.

Should a dosed subject terminate prematurely from the residential phase of the study, the 
Investigator will make every effort to complete the Early Termination evaluations as scheduled for 
Day 3 before the subject is discharged. 
Subjects discontinuing after randomization but before dosing may be replaced. Subjects 
discontinuing after dosing may be replaced. If a dosed subject is withdrawn or withdraws due to 
safety reasons, they will not be replaced. Decisions to replace dosed subjects for other reasons will 
be made on a case-by-case basis depending on the timing of the discontinuation. 
4.4 
Study Enrollment Procedures 
Subjects will be identified by a unique ID number and initials throughout their participation in the trial. 
Once randomized, each subject will also have a unique randomization number. Subjects will only be 
identified numerically in final data tables and listings; no initials will be presented. 
Sufficient numbers of subjects will be enrolled into the Screening Phase to ensure at least 8 eligible 
subjects are available for dosing in each dosing group. 
A subject who screen fails at any point pre-dose (Screening through Day 1 pre-dose, inclusive) due 
to exclusionary findings may not be rescreened for the study. 
A subject who has been screened but not randomized for non-exclusionary reasons may still qualify 
for entry into the study as follows: 
A subject admitted to the clinical research unit based on acceptable Day -1 findings but who is not 
randomized on Day 1 (i.e., alternate or logistical/administrative reason) is permitted to remain in the 
clinical research unit for up to an additional 2 overnight stays to be re-evaluated for dosing. Dosing 
must occur within 28 days of Screening. Subjects must remain ‘residential’ during this time and must 
follow all other restrictions as previously outlined. Day -1 tests need not be repeated, however, any 
new medical history must be recorded and all Day 1 pre-dose tests must be performed on the ‘new’ 
Day 1. 
A subject admitted to the clinical research unit based on acceptable Day -1 findings but who is not 
randomized on Day 1 (i.e. alternate or logistical/administrative reason) and is discharged from the 
clinic may return once to repeat Day -1 tests and be re-evaluated for dosing. Dosing must occur 
within 28 days of Screening and all Day -1 procedures must be repeated. 
A subject who has been screened but not randomized due to non-exclusionary reasons and is 
outside the 28 day Screening window may be rescreened once. The subject must repeat the entire 
Screening visit. 
 Subject Recruitment and Retention 
Participants may be recruited from clinics or existing recruitment registries at the participating site. 
Postings may be placed on the participating site website. Flyers about the study may be sent to 
community neurologists. Webinars will be conducted for participant recruitment as needed. Interested 
participants will be contacted by the investigators or their staff and invited to participate. These 
recruitment strategies will include a mechanism by which the patients can provide their contact 
information.

 Randomization/Treatment Assignment 
An independent statistician will be responsible for generating the randomization scheme. 
The randomization scheme for this study will assign subjects to treatment or placebo in sentinel 
groups of 2 subjects with a 1:1 ratio (1 drug: 1 placebo), followed by groups of 6 individuals with a 5:1 
ratio (5 drug: 1 placebo), so that in each dosing cohort 6 subjects will receive MW151 and 2 subjects 
will receive placebo (see Table 3). Randomization numbers will start at 001.

After a subject is confirmed eligible for dosing on the afternoon/evening of Day -1 or morning of Day 
1, the study staff will allocate the next available randomization number to the subject, starting at the 
lowest number and continuing in a consecutive manner. 
 
Once a randomization number has been assigned, it cannot be re-assigned to any other subject. To 
respect treatment allocation and the overall study design, replacement subjects will receive the same 
treatment assignment as the original subject who is being replaced and their randomization number 
will be the initial randomization number plus 100 (i.e. a subject replacing ‘009’ will have the number 
‘109’).

5 STUDY INTERVENTIONS/STUDY MEDICATION/STUDY DRUG 
5.1 
Study Medications/Interventions, Administration, and Duration 
Drug or placebo will be administered orally in a filled capsule. Subjects will receive a single dose on 
day 1. Subjects will be dosed in an inpatient facility at the study site. 
At the proposed single clinical doses, adverse events related to target organ toxicities observed in 
non-clinical studies (testicular toxicity, QT interval prolongation) are unlikely to occur, but the 
investigator should be aware of these findings. There may be other risks, discomforts, or side effects 
that are currently unknown. These may include rashes, GI upset, or allergic reactions. 
After dosing, the Medical Monitor may prescribe any concomitant therapy deemed necessary to 
provide adequate supportive medical care. More details are given below. 
5.2 
Handling of Study Medications/Interventions 
Drug appearance, packaging and storage: The preparation of the study drug (filling of MW151 
drug substance into capsules without any excipients just before use) will be done by a qualified 
compounding pharmacy, and supplied to the site pharmacy. The study medication will be prepared 
for the required dose of each cohort. 
Study drug must always be stored in a secure location with access limited to designated study staff 
members. Study drug must be stored in a refrigerator at 2-8oC. Temperature logs will be maintained 
to verify correct storage conditions throughout the trial. 
Blinding and Emergency Code Envelopes: During this study, subjects and all study staff will be 
blinded to treatment allocation, except as noted below. Sponsor staff will be blinded to treatment 
allocation. However, Sponsor staff member(s) will be designated as unblinded to enable handling and 
review of PK data and drug accountability prior to database lock. Safety reviews between dosing 
cohorts will be performed in a blinded manner unless the data warrants unblinding due to safety 
concerns. 
The site pharmacy staff will be unblinded so that the appropriate test article (MW151 or placebo) can 
be dispensed appropriately as per the randomization schedule. The unblinded staff will not participate 
in any other study evaluations. 
In an emergency, the blind may be broken and unblinded safety data provided to the Medical Monitor 
if requested. Should unblinding of the Medical Monitor occur, this must be recorded in the source 
documents and the study PI should be notified as soon as possible. Breaking of the blind for non-
safety reasons will be considered a protocol violation. 
Product Preparation: Drug and matched placebo will be provided as an oral capsule(s) containing 
the appropriate amount of drug required for each cohort. All doses will be administered to the 
subjects by appropriately qualified personnel. 
Product Accountability: The site will use Sponsor-approved product accountability records. The 
completeness and accuracy of all accountability records will be monitored throughout the course of 
the study, including study drug receipt, preparation and use, destruction and return.

Upon receipt of a shipment of MW151, site staff will check the condition of the shipping containers 
and perform a reconciliation of study drug with the shipment logs, notifying the monitor immediately of 
any problems. In situations where study drug (MW151 or placebo) is dispensed but not used, the 
dispensed medication should be returned to the pharmacy and segregated until review by the 
unblinded monitor. After accountability is complete, unused study drug can be discarded according to 
the study site’s normal procedures. All study drug (used/unused) remaining at the completion of the 
study will either be returned to the pharmacy or will be destroyed at the study site. In case of the 
latter, the study site will supply destruction records to the investigator. 
In accordance with local regulatory requirements, the investigator, designated site staff, or head of 
the medical institution (where applicable) must document the amount of investigational product 
dispensed and/or administered to study subjects, the amount received from the central pharmacy, 
and the amount destroyed upon completion of the study. An investigator is responsible for ensuring 
product accountability records are maintained throughout the course of the study. The inventory will 
include details of MW151 received and dispensed to subjects, batch, and ID numbers. All unused 
capsules must be kept until reconciliation of delivery records with accountability logs by the monitor. 
After the monitor has performed accountability, the site will be instructed to either destroy the 
remaining study medication or return it to the Central Pharmacy or manufacturer. An accounting must 
be made of any drug deliberately or accidentally destroyed. Discrepancies between the amount of 
MW151 received and dispensed drug must be reconciled. 
5.3 
Concomitant Interventions 
After dosing, the site PI or qualified designee may prescribe any concomitant therapy deemed 
necessary to provide adequate supportive medical care. After discharge the subject should refrain 
from any medication other than that required for supportive medical care. All medications will be 
recorded in subject charts. 
 Required Concomitant Medications/Interventions 
Subjects are required to fast for at least 10 hours before all safety laboratory samples. Subjects are 
allowed water ad libitum. Breakfast may be given on Day 1 before dosing; other meals and snacks 
may be served at the study site’s standard times. The study site will provide subjects with standard 
meals and snacks while in the Phase 1 unit. The daily menu information will be included in the final 
clinical report as an appendix. 
 Prohibited Medications/Interventions 
Describe procedure for handling situation(s) when subject uses prohibited intervention during study 
participation. This may also be detailed in section 8: Criteria for Intervention Discontinuation. 
Any antibiotic use within 14 days of Day 1 is prohibited. Subjects are not permitted any prescribed 
medication (other than birth control or other stable medications previously approved by the medical 
monitor) or any over-the-counter medication, health/herbal supplement or vitamin by any route of 
administration within 10 days of Day 1 inclusive other than to manage an adverse event. 
Subjects are required to refrain from smoking, using nicotine-based products, alcohol and food or 
drinks containing caffeine throughout the residential phase. Subjects should refrain from strenuous 
physical exercise for 48h prior to entry into the Phase 1 unit until the Follow-up visit. Subject should 
refrain from alcohol consumption after discharge until the Follow-up visit is complete.

Timing of Study Activities 
Order of Tests: When several assessments are required at the same time point, evaluations should 
be completed in the following order, with PK sample collection at the required time. As such, it is 
understood that ECGs and vital sign measurements may be performed before the actual time point to 
allow for rest times and procedures: 
• 
Fasting safety laboratory sample 
• 
ECG (supine) 
• 
Vital signs 
• 
PK sample 
o Allowable Windows: 
 
PK window for 15min, 30min and 1h post-dose samples: ± 5 minutes 
 
PK window for ≥ 2h post-dose samples: ± 10 minutes 
• 
Day 7 Follow-up visit: ± 1 day 
 Screening/Pre-Randomization Evaluations/procedures 
Screening: Having given written informed consent, each subject will be required to undergo a 
medical screen within 28 days of Day 1. The subject will undergo the following procedures: 
•

screening visit, they will be asked about their fasting status. If the subject states that 
they have not been fasting for the required time, laboratory samples will still be obtained 
and the laboratory requisition will be marked accordingly. The investigator will assess 
the results and if the glucose is within laboratory defined references or deemed not 
clinically significant by the PI or designee, then the laboratory test does not need to be 
repeated. In the event that the glucose is abnormal and potentially clinically significant, 
then the subject may be scheduled to come for an unscheduled visit to have a fasting 
laboratory glucose drawn. 
• 
Serum pregnancy test (females only) 
• 
Follicle Stimulating Hormone (suspected postmenopausal females only) 
• 
Alcohol screen (breathalyzer) 
• 
Hepatitis B, Hepatitis C, HIV screen 
• 
Urine drug screen 
• 
Quantiferon TB Gold PLUS test 
Once complete, the screening evaluations should be reviewed against inclusion/ exclusion criteria to 
determine the subject’s eligibility for continuation. The Sponsor may be involved in the eligibility 
review and the Medical Monitor may request subject exclusion for safety reasons. 
• 
For those subjects who fail study screening the reason for screen failure will be recorded in 
the Screening Log. Data for screen failures will not be entered into database for this study. 
Infection Screen: On Day -1, subjects will be screened for the presence of infection. This will be 
evaluated using physical examination findings, body temperature, evaluation of recent/current 
antibiotic use, any recent surgery, any evidence of dental abscess, unhealed skin lesions etc. 
Presence of, or the suggestion of infection are exclusionary. 
Neurological Examination: The neurological examination will include: 
Mental Status: Test for orientation to time, place and person: asking date, current location and what 
is his/her name. The subject should be able to follow at least one complicated command such as “lift 
your right shoulder”. 
Cranial Nerves 2-12: Test visual fields, visual acuity, pupillary reflexes, eye movements, fundoscopy, 
facial strength (including facial expression and mastication), hearing to finger rub, tongue, palate and 
head rotation movements, check for dysarthria and shoulder elevation. 
Motor System and Coordination: Test strength in upper and lower limbs bilaterally, pronator drift, 
finger tapping, rapid pronation and supination movements, finger-nose, heel shin, tandem gait, 
walking on heels. 
Reflexes: Test biceps, triceps, knee, ankle and plantar responses (Babinski’s reflex). 
Sensory System: Test light touch, vibration, Romberg test. 
Safety Exclusions: Safety laboratory tests performed as part of Screening and Day -1 assessments 
may not be repeated if any quantitative exclusion criteria are met.

Pre-dose vital signs (Screening, Day -1, Day 1 pre-dose) may be repeated once at each visit to 
confirm exclusionary findings. In cases where the initial assessment is exclusionary and the repeat 
assessment is not, the Investigator must evaluate both sets of data and determine whether or not the 
subject may continue. 
Pre-dose ECGs (Screening, Day -1 pre-dose) may not be repeated if any quantitative exclusion 
criteria (QTcF) are met. Other abnormal ECGs may be repeated once at each visit to confirm non-
quantitative exclusionary findings. In cases where the initial assessment is exclusionary and the 
repeat assessment is not, the Investigator must evaluate both sets of data and determine whether or 
not the subject may continue. 
Subjects must not be randomized if there are any clinically significant pre-dose findings on vital signs, 
ECGs, safety laboratory tests, physical examinations and/or neurological examinations. 
Electrocardiogram: A standard 12-lead ECG will be collected at required time points (after lying 
quietly for 5 minutes). ECG parameters including HR, PR, QT, QTcB, QTcF, QRS, and RR intervals 
will be collected. 
At Day -1, pre-dose triplicate ECG tracings will be obtained and will serve as the Baseline. At all other 
time points, a single ECG tracing will be obtained. 
The tracings may be reviewed and reported both locally by the site PI or qualified designee and by a 
blinded Medical Monitor. The Day -1 pre-dose ECGs will be evaluated for Inclusion/ Exclusion by the 
Investigator and the Investigator’s evaluation will prevail for any immediate subject safety 
management purposes. All clinically significant (CS) values should be reported as AEs and recorded 
into the AE source document/eCRF. All ECG tracings and central reader reports will be filed with 
each subject’s chart. 
Vital Signs: Vital signs will include BP and HR. 
At each time point where vital signs are measured, heart rate and blood pressure will first be checked 
in the supine position and then in the standing position with at least 2 minutes between the supine 
and standing measurements. An appropriately sized cuff (cuff bladder encircling at least 80% of the 
arm) should be used to ensure accuracy of measurements. The arm used for measurements should 
be consistent throughout the study. 
 On-Study/On-Interventions Evaluations/procedures 
During the time the subject is in the Phase 1 unit, subjects’ observations about the tolerability of the 
capsule administration will be recorded. 
Admission Procedures (Day -1): Subjects will arrive at the Phase 1 unit on Day -1 and will undergo 
procedures:

Treatment-related AEs ongoing at the Follow-up assessment will be followed until resolution or 
deemed stable, where feasible. Any Follow-up safety laboratory tests that are deemed clinically 
significant by the Investigator will be repeated and followed until stabilization at the discretion of the 
Investigator/Sponsor. 
 Study Medication/Intervention Discontinuation Evaluations/Procedures 
Sufficient numbers of subjects will be enrolled into the Screening Phase to ensure 8 eligible subjects 
are available for dosing in each dosing group. 
Subjects may withdraw from the study for any reason at any time. The Investigator may discontinue 
subjects from the study in order to protect subject safety and/or if the subject is unwilling or unable to 
comply with required study procedures. Subjects may also be withdrawn from the study if the 
Sponsor or Regulatory Authorities terminate the study prior to its planned end date. 
Should a dosed subject terminate prematurely from the residential phase of the study, the 
Investigator will make every effort to complete the Early Termination evaluations, which consist of the 
procedures scheduled for Day 3 before a subject is discharged and a physical examination. A PK 
sample may be drawn at the discretion of the Investigator. 
Subjects discontinuing after randomization but before dosing may be replaced. Subjects 
discontinuing after dosing may be replaced. If a dosed subject is withdrawn or withdraws due to 
safety reasons, they will not be replaced. Decisions to replace dosed subjects will be made on a 
case-by-case basis depending on the timing of the discontinuation. 
 Pregnancy 
Women who are pregnant at screening or on Day -1 testing will not be allowed to enter into the study. 
The likelihood of a female subject becoming pregnant while receiving MW151 is highly unlikely 
because of the requirement for a negative pregnancy test on Day -1 and the requirement that an 
acceptable barrier form of birth control be used during the study. Therefore, a pregnancy consent 
form will not be needed and no additional evaluations will take place.

SPECIAL INSTRUCTIONS AND DEFINITIONS OF EVALUATIONS 
 Informed Consent 
Written informed consent will be obtained from each participant by a study team member authorized 
to obtained consent. Informed consent will be obtained before any study-specific procedures or 
assessments are performed and after the aims, methods, anticipated benefits, and potential hazards 
are explained. The participant’s willingness to participate in the study will be documented in writing in 
a consent form, approved by the IRB, which will be signed by the participant with the date of that 
signature indicated. The investigator will keep the original consent forms and copies will be given to 
the participants. It will also be explained to the participants that they are free to refuse entry into the 
study and free to withdraw from the study at any time without prejudice to future treatment. Written 
and/or oral information about the study in a language understandable by the participant will be given 
to all participants. HIPAA guidelines for confidentiality and the principles of medical ethics will be 
adhered to during the study. 
 Protocol Amendments and Study Termination 
All revisions and/or amendments to this protocol must be approved in writing by the Sponsor and the 
IRB. The Investigator will not make any changes to the conduct of the study or the protocol without 
first obtaining written approval from the Sponsor and the IRB, except where necessary to eliminate 
an apparent immediate hazard to a study subject. 
The Sponsor reserves the right to discontinue the study at a clinical study site(s) for safety or 
administrative reasons at any time. Should the study be terminated and/or the clinical study site 
closed for any reason, all documentation and study medication pertaining to the study must be 
returned to the Sponsor or its representative. 
 Pharmacokinetic Studies 
Samples will be taken as described in Sections 6.1 and 6.2. Blood samples can be drawn via direct 
venipuncture or an indwelling catheter may be used. Catheters will be flushed with saline before and 
after sampling. Heparin flushing is not permitted. 
If using a catheter, after the saline flush, withdraw and discard approximately 1.5 mL of blood before 
obtaining the sample to avoid sample dilution. Next, take 5 mL of blood into a pre-labeled plasma 
collection tube. Refer to the Laboratory Manual for the specific type of plasma collection tube to be 
used and for detailed sample processing instructions. 
To avoid cross contamination of MW151 and placebo samples, separation of plasma aliquots should 
be done for one subject at a time, changing gloves between subject samples. 
Following processing, plasma will be split into two aliquots. The 1st tube will be sent for PK analysis, 
and the 2nd tube will be a PK retention sample. Until samples are shipped to the analytical facility they 
will be frozen at -70°C (+ 10°C). Samples will be sent frozen on sufficient dry ice to maintain frozen 
conditions for at least 72 hours. The Sponsor will provide direction regarding the timing of sample 
shipment and sample destruction as applicable.

7 MANAGEMENT OF ADVERSE EXPERIENCES 
Adverse Event: An adverse event is any untoward medical occurrence associated with the use of a 
drug in humans, whether or not considered drug related. An adverse event (also referred to as an 
adverse experience) can be any unfavorable and unintended sign (e.g., an abnormal laboratory 
finding), symptom, or disease temporally associated with the use of a drug, without any judgment 
about causality. An adverse event can arise from any use of the drug (e.g., off- label use, use in 
combination with another drug) and from any route of administration, formulation or dose, including 
an overdose. 
Adverse Reaction: An adverse reaction means any adverse event caused by a drug. Adverse 
reactions are a subset of all suspected adverse reactions for which there is reason to conclude that 
the drug caused the event. 
Suspected Adverse Reaction: Suspected adverse reaction means any adverse event for which 
there is a ‘reasonable possibility’ that the drug caused the adverse event. For the purposes of IND 
safety reporting, ‘reasonable possibility’ means there is evidence to suggest a causal relationship 
between the drug and the adverse event. A suspected adverse reaction implies a lesser degree of 
certainty about causality than adverse reaction, which means any adverse event caused by the drug. 
The types of evidence that would suggest a casual relationship between the drug and the adverse 
event include, but are not limited to: 
A single occurrence of an event that is uncommon and known to be strongly associated with drug 
exposure (e.g., angioedema, hepatic injury, Stevens-Johnson Syndrome) 
One or more occurrences of an event that is not commonly associated with drug exposure, but is 
otherwise uncommon in the population exposed to the drug. 
An aggregate analysis of specific events observed in a clinical trial (such as known consequences of 
the underlying disease or condition under investigation or other events that commonly occur in the 
study population independent of drug therapy) that indicates those events occur more frequently in 
the drug treatment group than in a concurrent or historical control group. 
Unexpected Adverse Event: An adverse event or suspected adverse reaction is considered 
‘unexpected’ if it is not listed in the Investigator Brochure or is not listed at the specificity or severity 
that has been observed. 
Serious Adverse Event: An adverse event or suspected adverse reaction is considered ‘serious’ if, 
in the view of either the Medical or Safety Monitor, it results in any of the following outcomes: 
• 
Death 
• 
A life-threatening adverse event 
• 
In-patient hospitalization or prolongation of existing hospitalization 
• 
Persistent or significant incapacity or substantial disruption of the ability to conduct normal 
life functions 
• 
Congenital anomaly/birth defect

Page 43 of 55 
Important medical events that may not result in death, be life-threatening, or require hospitalization 
may be considered serious when, based upon appropriate medical judgment, they may jeopardize 
the subject and may require medical or surgical intervention to prevent one of the outcomes listed in 
this definition. Examples of such medical events include allergic bronchospasm requiring intensive 
treatment in an emergency room or at home, blood dyscrasias or convulsions that do not result in 
subject hospitalization, or the development of drug dependency or drug abuse. 
Life Threatening Adverse Event: An adverse event or suspected adverse reaction is considered 
‘life-threatening’ if, in the view of either the Investigator or Sponsor, its occurrence places the subject 
at immediate risk of death. It does not include an adverse event or suspected adverse reaction that, 
had it occurred in a more severe form, might have caused death. 
Reporting a Serious Adverse Event to the Sponsor: The Investigator is required to inform the 
Medical Monitor by e-mail/telephone/fax within 24h of his/her becoming aware of any serious adverse 
event. The notification should be followed by a written report within 1 working day of such an event. 
The follow up observation period for the subject(s) affected will be jointly decided upon by the 
Investigator and the Medical Monitor. The Investigator is responsible for notification of serious 
adverse events to the applicable Institutional Review Board/Independent Ethics Committee 
(IRB/IEC). The Sponsor is responsible for all IND Safety Reporting to the US Food and Drug 
Administration (FDA). 
Collection of Safety Information: Adverse events (AEs) and serious adverse events (SAEs) will be 
monitored and reported throughout the study from the time of dosing to the end of study. Each 
subject will be monitored for AEs throughout the study. Subjects will be asked “how are you feeling?” 
during each study visit and throughout the day during the residential phase of the study. AEs will be 
followed to resolution/stabilization, where feasible/possible, regardless of whether the subject is still 
participating in the study. Follow-up on AEs may include subject referrals to specialists and/or other 
health care providers. When applicable, the Investigator will obtain reports and/or medical records 
from non-study providers regarding the AE. In cases of AEs such as rashes, photographs may be 
taken for the purpose of documentation. Due regard for subject confidentiality will be employed. 
The Investigator is not obliged to follow-up with subjects for AEs or SAEs that begin after study 
completion, however if an SAE is reported to the Investigator after a subject has completed the study, 
and it is possibly related to the study drug, then the Investigator will report it to the Sponsor. 
All abnormal laboratory analytes, ECG results, vital signs and examination findings will be reviewed 
by the Investigator for clinical significance. If the Investigator deems a post-dose finding to be 
clinically significant, it will be documented as an AE. Pre-dose clinically significant findings are 
exclusionary. Pre-dose events will be analyzed separately from treatment emergent AEs in the final 
analysis. 
Assessment of Adverse Events: Investigators will assess each AE based on the following 
definitions. 
7.1 
Intensity (Severity) 
Mild: The AE is generally transient, does not interfere with usual activities, and is easily tolerated by 
the subject. 
Moderate: The AE causes sufficient discomfort and interferes with usual activities.

Protocol MW151-101: 14 October 2020 
ImmunoChem Therapeutics, LLC 
Confidential 
Page 44 of 55 
Severe: The AE causes considerable interference with usual activities and may be incapacitating. 
7.2 
Relationship. Unrelated = None, Remote 
None (unrelated, not related, no relation): 
An unreasonable temporal relationship between administration of the study drug and the onset of the 
AE (e.g. the event occurred either before, or too long after administration of the study drug for it to be 
considered drug-related); 
A causal relationship between the study drug and the AE is biologically implausible (e.g. death as a 
passenger in an automobile accident); 
A clearly more likely alternative explanation for the AE is present (e.g. typical adverse reaction to a 
concomitant drug and/or typical disease-related event). 
Remote (unlikely, doubtful, improbable): 
There is little evidence to suggest there is a causal relationship and there is another reasonable 
explanation for the event. 
7.3 
Related = Possible, Probable 
• 
Possible: There is some evidence to suggest a causal relationship (e.g. the event 
occurred within a reasonable time frame after administration of the study drug); however, 
the influence of other factors may have contributed to the event (e.g. the subject’s 
clinical condition, other concomitant medications, or concurrent illness). 
• 
Probable: There is evidence to suggest a causal relationship and the influence of other 
factors is unlikely. 
Consider the following when assessing causality: 
• 
Temporal associations between the study drug and the event 
• 
Pre-existing risk factors or concurrent illness 
• 
A plausible mechanism

8 CRITERIA FOR INTERVENTION DISCONTINUATION 
8.1 
Intolerable Dose 
After the safety review, if the Medical Monitor, based on good clinical judgement, considers a dose 
level to be intolerable, then dose escalation to the next level will not proceed. Depending on the 
duration and potential seriousness of safety findings, the Sponsor and Investigator will determine 
whether the current dose level may be repeated, or if a lower dose level may be tested. 
If any of the following sentinel halting criteria are met the rest of the cohort will not be dosed until 
review by the Medical and Safety Monitors, Sponsor and Investigator: 
• 
Any subject develops a Grade 3 (severe) AE that is related to the study drug within 24 
hours of dosing. 
• 
Any subject develops an SAE related to the study drug. 
The following criteria constitute specific study halting criteria: 
• 
Two or more subjects experience AEs of severe intensity in the same organ class 
(Grade 3 according to the “Toxicity Grading Scale for Healthy Adult and Adolescent 
Volunteers Enrolled in Preventive Vaccine Clinical Trials,” Version September 
2007) regardless of relatedness to study drug. 
• 
One subject with a reported SAE, unless that SAE is determined to be clearly unrelated 
to the investigational drug product. 
• 
Occurrence of a life-threatening allergic/hypersensitivity reaction (anaphylaxis) in any 
subject, manifested by bronchospasm with or without urticaria or angioedema requiring 
hemodynamic support with pressor medications or mechanical ventilation. 
• 
Death of a dosed subject following dosing and prior to the subject’s last visit that was not 
the result of trauma or accident, regardless of relatedness to study product. 
• 
Any other event(s) in the good clinical judgment of the responsible physician that is 
thought to be related to investigational product and comprises a serious risk to subject 
safety. 
If any of the following dose escalation halting criteria are met escalation to the next planned dose 
cohort will not proceed until all available study data have been reviewed by the DSMB: 
• 
Any subject develops an SAE related to the study drug 
• 
Any subject experiences a Grade 3 (severe) AE related to the study drug 
• 
2 or more subjects in a cohort experience a Grade 2 (moderate) or greater AE that is 
related to the study drug and is of the same type (preferred term) and occurring in the 
same SOC.

9 STATISTICAL CONSIDERATIONS 
9.1 
General Design Issues 
Detailed statistical analysis plans will be created for the study and signed off in advance of database 
lock. One plan will be created for the analysis of PK data and a separate plan will be created for the 
analysis and presentation of all other study data. General statistical approaches are presented below. 
Baseline is defined as the last evaluation before dosing. 
Safety Analysis: All subjects who receive any study treatment will be included in the safety analysis 
grouped by treatment received. Statistical analysis of safety data will be descriptive. 
For continuous variables, summaries will include sample size, mean, standard deviation, minimum, 
and maximum. For categorical variables, the summaries will include frequencies and corresponding 
percentages. No inferential hypothesis testing will be performed on the safety variables. Repeat or 
unscheduled results will not be included in the summaries, but will be listed. Data from placebo 
subjects will be pooled for final presentations. Confidence intervals (90%, 95%) may be used in 
safety summaries. 
Adverse Events: AEs will be coded using the Medical Dictionary for Regulatory Activities (MedDRA). 
AEs will be listed and summarized by treatment group and dose level. Where applicable, AEs may 
also be summarized by severity, seriousness, relationship to study treatment and by system organ 
class and preferred term. The number and percentage of subjects who experience events will be 
shown in the summaries. Listings for all AEs will be presented. 
A treatment-emergent AE is an AE, regardless of relationship to study drug that occurs during or after 
the first dose of study treatment. 
Laboratory Assessments: Summary statistics of observed and change from baseline data will be 
presented for each treatment group and dose level where applicable. Summary statistics will include 
number of subjects, mean, standard deviation, minimum, and maximum. Shift tables summarizing the 
numbers of subjects shifting from normal pre-dose values to abnormal post- dose values will also be 
presented where applicable. Listings for all laboratory assessments will be presented. 
Vital Signs (BP, HR, Body Temperature): Summary statistics for BP and HR and change from 
baseline (predose) summaries will be presented for each treatment group and dose level where 
applicable. Summary statistics will include number of subjects, mean, standard deviation, minimum, 
and maximum. Listings for all vital signs will be presented. 
Post-dose clinically notable vital signs will be listed and summarized by treatment and dose. Notable 
abnormalities are indicated in Table 5 below:

Pharmacokinetic Analysis: The plasma concentrations of MW151 will be determined, and used to 
estimate appropriate PK parameters including Cmax, Tmax, AUC, T½ and Kel by non- compartmental 
analysis. The PK analysis population will include all subjects who received the active study drug and 
who have sufficient MW151 plasma concentrations to calculate at least 1 PK parameter. 
PK parameters will be listed for each individual subject and summarized for each dose level; the 
summary will consist of number of subjects, arithmetic mean, standard deviation, and geometric 
mean, coefficient of variation, minimum, median, and maximum. Profiles for each subject will be 
presented graphically. Additionally, a mean profile will be presented by treatment group and dose 
level. 
The PK analysis will be conducted at a facility selected by the Sponsor. PK data will be provided to 
the Sponsor for inclusion into the final clinical study report. 
9.2 
Administrative and Regulatory Considerations 
 Good Clinical Practice 
The study will be conducted in accordance with good clinical practice (ICH GCP) and all applicable 
regulations including the ethical principles of the Declaration of Helsinki (Edinburgh 2000, with Note 
of Clarification, Tokyo 2004). 
 Informed Consent 
The Sponsor or designee will provide the Investigator with a template ICF for the study, which may 
be modified for local use. A study team member authorized to obtain consent will obtain a written ICF 
from each study subject prior to the performance of any study-related procedures. 
Consent will be obtained only after full disclosure of the nature of the study, its risks and benefits, in 
accordance with local and federal regulations and guidelines. The fact that informed consent was 
obtained, and the date upon which it was obtained, will be documented in each subject’s study 
records. 
If the ICF is amended at any time during the study, the Investigator must follow all applicable 
regulatory requirements to ensure review and approval of the amended consent form by the IRB/IEC. 
Subjects must sign the most current IRB/IEC-approved version of the ICF at the time of their 
participation in the study. 
 Ethical Review 
The Investigator or designee will prepare and submit all required documentation and obtain local 
IRB/IEC approval to implement the study prior to the conduct of any study procedures. At a minimum, 
the study protocol, ICF, Investigator’s Brochure, and study-related advertisements and promotional 
materials will be submitted. 
If it is necessary to amend the protocol and/or ICF during the course of the study, the Investigator 
must ensure that the IRB/IEC reviews and approves these amended documents. No amendments to 
the study protocol should be made without the agreement of the Investigator and Sponsor as well as 
the IRB/IEC, where applicable.

The Investigator will maintain documentation of the composition of the IRB/IEC as well as all 
correspondence with the IRB/IEC. The Investigator will comply with local requirements for routine 
reporting to the IRB/IEC, as well as local and government requirements for notifying the IRB/IEC of 
SAEs. The Investigator will prepare a final study report and submit it to the IRB/IEC within 3 months 
of study completion. The Investigator or designee will provide Sponsor or designee with copies of 
IRB/IEC approval notices, correspondence, annual reports, and final study reports. 
 Protocol Compliance 
The study will be conducted in compliance with the protocol. The Investigator is responsible for 
ensuring compliance by all study staff members. Deviations from protocol-specified procedures will 
be documented in subjects’ study records. 
10 DATA COLLECTION, SITE MONITORING, AND ADVERSE 
EXPERIENCE REPORTING 
10.1 Data Management 
Site personnel will collect, transcribe, correct, and transmit the data onto source documents, CRFs, 
and other forms used to report, track and record clinical research data. The clinical site will be 
monitored to ensure compliance with data management requirements and Good Clinical Practices. 
All study data will be collected via systems that comply with all applicable guidelines regarding patient 
confidentiality and data integrity. 
 Registration 
Registration of participants on this protocol will employ an interactive data system in which the clinical 
study site will attest to the participant’s eligibility as per protocol criteria and obtain appropriate 
informed consent. IRB approval for the protocol must be on file at the institution before accrual can 
occur from the clinical study site. 
A system of coded identifiers will be used to protect participant confidentiality. When the participant is 
registered to participate in the study, the system will assign a participant ID number. To confirm the 
correct participant ID, the data entry system will require a second entry of the unique participant ID 
and compare for consistency. In this fashion, no personal identifiers would be accessible and the 
data will be collected on the correctly identified subject. 
 Documentation of Data 
As part of the responsibilities assumed by participating in the study, the Investigator agrees to 
maintain timely case histories for the subjects treated as part of the research under this protocol, 
including accurate source documentation. A CFR21, part 11 compliant electronic data capture 
system for source data will be developed and provided for use in the clinical study. The majority of 
source data will be recorded directly into data capture system; however some source data, including, 
but not limited to, AEs, concomitant medications and protocol deviations will be recorded on paper-
based source documents. Paper-based data will be entered into a separate clinical database, and will 
be merged with the electronic data capture system during processing and analysis. ECG readings 
are printed with a machine interpretation on the ECG. This is then reviewed by the study investigator. 
If there is a question with the interpretation, the investigator can ask a cardiologist for another read.

ECG data will be forwarded electronically for inclusion in data reporting and analyses. The 
Investigator will be responsible for ensuring that adequate checks are carried out on all study data. 
At the completion of the study, the Sponsor will receive a complete set of data for all subjects. 
 Source Document Verification 
All (100%) subject data (electronic and paper-based source) will be reviewed by the monitors for 
accuracy and consistency. This will be conducted with due regard to subject confidentiality. 
10.2 Data Management 
Data collection processes and procedures will be reviewed and validated to ensure completeness, 
accuracy, reliability, and consistency. A complete audit trail will be maintained of all data changes. 
Electronic consistency checks and manual review will be used to identify errors or inconsistencies. 
This information will be provided to the study site by means of electronic or manual queries. 
 Monitoring the Study Data 
The conduct of the study will be monitored by the Sponsor, or designee, to ensure compliance with 
applicable regulatory requirements and GCP. The study monitor will maintain necessary telephone 
and letter contact with the Investigative site. The study monitor will verify that the study is conducted 
in accordance with the currently approved protocol and any amendments and will monitor subject 
enrolment, completeness and accuracy of subject data and reporting and recording of AEs. 
The monitor will maintain current knowledge of the study through observation, review of study 
records and discussion of the conduct of the study with the Investigator and staff.  Monitoring will be 
conducted according to Good Clinical Practice and applicable government regulations. The 
investigator agrees to allow monitors access to the clinical supplies, dispensing and storage areas, 
and to the clinical files of the study subjects, and, if requested, agrees to assist the monitors. 
Safety monitoring will include careful assessment and appropriate reporting of adverse events. 
Medical monitoring will include contemporaneous assessment of serious adverse events. 
The DSMB will meet after each cohort is completed or as needed, and will review subject recruitment, 
AE’s, side effects, withdrawals, protocol violations, and inclusion/exclusion criteria. More frequent 
meetings will take place if necessary. Roles and responsibilities for the DSMB will be outlined in a 
separate DSMB charter document. 
The Safety Monitor will review all adverse events, in a blinded fashion, on a periodic basis. In 
addition, the monitor will review all events that meet the regulatory definition of a Serious Adverse 
Event, upon receipt of notification via the Electronic Data Capture (EDC) system. 
An adverse event (AE) is any unfavorable and unintended sign (including a clinically significant 
abnormal laboratory finding, for example), symptom, or disease temporally associated with a study, 
use of a drug product or device whether or not considered related to the drug product or device. FDA, 
Office of Human Research Protection (OHRP), and IRB requirements for reporting AEs will be 
followed. Subjects will be monitored for AEs from the time they sign consent until 30 days following 
permanent discontinuation of study drug. At that point, all ongoing AEs will be followed to resolution, 
but no new AEs will be recorded. The monitor/DSMB will review cumulative AEs; the frequency of this 
review will be determined by the monitor/DSMB in conjunction with the Protocol PI.

The Clinical Site Medical Monitor and research team (co-Investigators, research nurse, clinical trial 
coordinator) are responsible for identifying and reporting AEs and determining the relationship of the 
event to the study drug/study procedures. Aggregate reports blinded by treatment group, detailed by 
severity, attribution (expected or unexpected), and relationship to the study drug/study procedures, 
will be available for review by the monitor. A separate report detailing protocol compliance will also be 
available monthly for review by the Protocol PI and Safety Monitor, who will provide feedback to the 
site as needed. The Safety Monitor will advise the Protocol PI as to whether the protocol or informed 
consent document requires revision based on these reports. 
10.3 Inspection of Records 
The Investigator and institution involved in the study will permit trial-related monitoring, audits, 
IRB/IEC review, and regulatory inspection(s) by providing direct access to all study records, medical 
files, and source data to enable verification of the trial data. In the event of an audit, the Investigator 
agrees to allow the Sponsor, the FDA, or other Regulatory Agency access to all study records. 
The Investigator should promptly notify the Sponsor of any audits scheduled by any Regulatory 
Authority and promptly forward copies of any audit reports received to the Sponsor. 
 Records Retention 
In accordance with all applicable regulatory requirements, the Investigator will maintain a copy of all 
site records in a safe and secure location on completion of the study. The location of the Investigator 
file archive will be made known to the Sponsor at study conclusion and if the archive location 
changes, the Investigator will notify the Sponsor. Sponsor will archive study data according to their 
normal practice. 
 Quality Assurance 
The Investigator site, facilities and all data and documentation may be audited by an independent 
auditor. The Investigator must allow the auditor access to all relevant documents and be available to 
discuss any findings/issues.

INTRODUCTION 
 
MW01-2-151SRM (hereafter called MW151) is a CNS-penetrant, orally bioavailable, small 
molecule drug candidate that selectively suppresses stressor-induced proinflammatory 
cytokine overproduction with resultant amelioration of synaptic damage and cognitive 
impairment. The efficacy and pharmacodynamics of MW151 are evident across a dozen 
diverse animal studies where cytokine overproduction is a contributor to pathophysiology 
progression. MW151 exhibits efficacy, at low doses. It does not bring about 
immunosuppression or a non-selective anti-inflammatory action. There is no evidence of 
suppression of basal cytokine levels characteristic of homeostasis. Function at efficacy doses 
involves restoration to homeostasis after disease or injury induced increases.    
 
MW151 is being developed for the treatment of cognitive disorders. The development program 
is based on nonclinical evidence that MW151 improves neurocognitive outcomes in animal 
models of radiation therapy-induced cognitive impairment, Alzheimer’s disease and related 
dementias, and other cognitive disorders. 
The present first-in-human study will provide safety and pharmacokinetic (PK) information on 
single ascending doses (SAD) of MW151 to support decisions for continued clinical 
development. This study will assess the safety, tolerability, and PK profile of escalating single 
doses of MW151 in healthy adult participants. The trial design will be a double-blind, placebo-
controlled, SAD study of MW151 in healthy volunteers. Five dosing cohorts are initially planned. 
All subjects and the study personnel responsible for assessing adverse events (AEs) will be 
blinded. This statistical analysis plan (SAP) provides a more technical and detailed elaboration 
of the statistical analyses of safety and tolerability data as outlined in the protocol.  
 
In the study design, 40 healthy male and female volunteers, ages 18-50 years, will be dosed in 
1 of 5 dosing cohorts of 8 subjects each. Subjects will be admitted to the inpatient clinic on the 
day prior to dosing (Day -1) and will remain in the unit until discharge on Day 3.  A follow-up visit 
will be done on Day 7.  
 
A single dose of study drug or placebo will be administered as an oral capsule(s) on Day 1. Five 
different doses of MW151 will be evaluated in 5 sequential cohorts.  Dosing will start at the 
lowest dose, then escalate in the 2nd cohort, then escalate sequentially in the 3rd, 4th, and 5th 
cohorts. 
 
Cohort 1: Dose1: MW151/101 10 mg (or matched placebo), 1 x 10 mg capsule administered 
orally. 
Cohort 2: Dose2: MW151/101 20 mg (or matched placebo), 1 x 20 mg capsule administered 
orally. 
Cohort 3: Dose3: MW151/101 40 mg (or matched placebo), 2 x 20 mg capsule administered 
orally. 
Cohort 4: Dose4: MW151/101 80 mg (or matched placebo), 1 x 80 mg capsule administered 
orally. 
Cohort 5: Dose5: MW151/101 160 mg (or matched placebo), 2 x 80 mg capsule administered 
orally. 
As a safety consideration, two sentinel subjects in each cohort will be administered MW151 or 
placebo in a 1:1 ratio.  Dosing of the remaining subjects in a cohort may proceed after review of 
sentinel subject safety and tolerability data collected during the first 24 hours of dosing and

determination that no stopping rules are met.  The remaining 6 subjects will be randomized in a 
5:1 ratio. The remaining subjects in each cohort will be dosed sequentially, not simultaneously. 
After the completion of each cohort (Cohorts 1-5), the Data Safety Monitoring Board (DSMB) will 
review all available safety data before the dosing of the sentinel subjects of the next cohort. 
Data from Cohorts 1-5 will be reviewed in a blinded manner, unless the findings suggest the 
triggering of a stopping rule, in which case the data for the subjects in question may be 
unblinded (e.g., if a drug related serious AE [SAE] occurs, identifying whether the subject 
received MW151 or placebo to determine whether the stopping rule should be triggered). Doses 
may be varied based on the safety review, but the maximum dose will not exceed 160mg. 
Should the safety data warrant, dose levels may be reduced or additional cohorts added in 
order to generate a comprehensive understanding of the clinical dose range. Should additional 
cohorts be required above the planned 5 cohorts or doses within the planned cohorts changed, 
a protocol amendment will be submitted to the FDA and the Independent Ethics Committee for 
approval before implementation. 
Screening will be conducted in the 28 days prior to inpatient admission. After giving written 
informed consent, each subject will undergo a medical screen consisting of the following 
procedures: demographics; medical history; concomitant medication review; body temperature; 
12-lead ECG; vital signs (BP, HR); physical exam; alcohol and drug screen; Hepatitis B, 
Hepatitis C, HIV, Columbia Suicide Severity Rating Scale and TB screens; and safety laboratory 
work and pregnancy testing.  
 
One day prior to dosing (Day -1), subjects will be admitted to the Duke Early Phase Research 
Unit (DEPRU) Phase 1 unit for final qualification assessments. These assessments will include 
inclusion/exclusion review, medical history, physical exam, infection screen, body temperature, 
alcohol and drug screen, vital signs, pregnancy test, neurological exam, and safety laboratory 
tests.  
 
A single dose of study drug or placebo will be administered as an oral capsule(s) on Day 1. 
During dosing, subjects will be continuously monitored with 12-lead ECG, blood pressure, and 
heart rate.  Plasma samples will be drawn at sequential time points for PK analysis. 
 
Subjects will remain in the clinical research unit until discharge on Day 3. Follow-up will be done 
through a clinic visit on Day 7. The follow-up visit will consist of safety lab work, body temperature, 
ECG, vital signs, concomitant medication review, and assessment of adverse events (AEs).

STATISTICAL ISSUES 
 
7.1 
GENERAL ANALYSIS CONVENTIONS 
 
General statistical approaches are presented below.   
All subjects in the Safety Population will be included in the safety analysis grouped by cohort 
and treatment group. Statistical analysis of safety data will be descriptive.  
Baseline is defined as the last assessment prior to dosing of study medication.   
For continuous variables, summaries will include sample size, mean, median, standard 
deviation, minimum, and maximum.  For categorical variables, the summaries will include 
frequencies and corresponding percentages. No inferential hypothesis testing will be performed. 
Repeat or unscheduled results will not be included in the summaries, but will be listed. Data 
from placebo subjects will be pooled for final presentations.   
 
Missing data results will not be imputed. Data summaries and analyses (e.g. means) will be 
calculated using all available data.  If the start day for an AE is missing, day of study drug 
administration will be used and AE will be considered treatment emergent.  Neither month nor 
year will be imputed for AE. 
Statistical analyses will be performed in SAS, Version 9.4 or newer.

DETERMINATION OF SAMPLE SIZE 
 
This trial is designed to investigate the safety, tolerability, and PK properties of the drug MW151 
in a dose escalation Phase Ia study. The number of subjects is based upon the need to gain 
this knowledge in healthy individuals using as few subjects as possible. Since this is the first 
study of MW151 in humans, there is no prior experience upon which to base estimates of 
variability for the PK responses to SAD treatment with MW151. No power analysis is conducted 
but the cohort size is based on accepted standards in similar Phase I studies: 8 subjects per 
dose with 6 randomly assigned to active drug while the remaining 2 subjects receive placebo. 
Eight subjects per cohort was deemed sufficient for obtaining an adequate preliminary 
description of the responses of interest.

WHY IS THIS STUDY BEING DONE?
The purpose of this study is to find out whether an investigational drug is safe and well tolerated. 
“Investigational” in the context of a clinical study means the drug is being tested for safety and 
effectiveness and has not been approved by the FDA for use in the United States. In this informed 
consent form, the investigational drug will be referred to as MW151 HCl. The study will also measure 
how the drug is moved to the bloodstream after administration, and how long it takes for the body to 
remove the drug from the bloodstream. 
MW151 HCl is being studied as a possible treatment for people with brain tumors who suffer from 
memory loss as a consequence of radiation therapy. Research studies conducted in animals and in test 
tubes have shown that MW151 HCl can reduce the amount of brain inflammation that occurs in the first 
few hours to days after the radiation dose. In these research studies, animals that received MW151 HCl 
were shown to recover better and faster.  
MW151 HCl has been given to humans at a single dose of 10 mg.  This study will look at the safety and 
tolerability of MW151 HCl at higher doses (20, 40, 80, 160 mg) and will look at how the amount of 
drug in the blood changes over time.   
HOW MANY PEOPLE WILL TAKE PART IN THIS STUDY?
Approximately 32 female volunteers (subjects) will take part in this study at Duke (8 subjects at each 
dose level). It may be necessary to screen as many as 80 subjects to ensure 32 people are able to 
complete the study. Duke is the only site for this study.
WHAT IS INVOLVED IN THE STUDY?
You will be randomly assigned (like the flip of a coin) to receive either MW151 HCl or placebo.  A 
placebo is an inactive substance given in the same form as the study drug. The first two volunteers dosed 
will have a 1 in 2 (50%) chance of receiving MW151 HCl or a placebo. Of remaining six subjects you 
have a 5 in 6 (83%) chance of receiving MW151 HCl and a 1 in 6 (17%) chance of receiving a placebo. 
Neither you nor the study doctor will know if you are getting MW151 HCl or placebo. However, in an 
emergency, the study doctor can find out.  
You will get one dose of study drug on Day 1. You will receive study drug by mouth in the form of a 
capsule. 
The planned dosing in the study is: 
Group 1 (8 volunteers): 10 mg of MW151 HCl or placebo
Group 2 (8 volunteers): 20 mg of MW151 HCl or placebo

For safety reasons, the first 24 hours of safety data from the first 2 volunteers in each group will be 
reviewed before the rest of the volunteers may receive study drug. After all 8 volunteers in Group 2 are 
finished, safety information from Group 2 will be reviewed by the study doctor and the medical and 
safety monitors before proceeding to the next group. Similar procedures will be followed for the 
remaining groups.
The study doctor will talk to you about the things you must do or not do to participate. Please tell your 
regular health care providers and any emergency care providers that you are in this research study.
If you agree to be in this study, you will be asked to sign and date this consent form.  You will have the 
following tests and procedures performed at the Screening Visit to make sure that you are eligible. The 
Screening Visit will take about 2-3 hours to complete. 
 
Screening Visit 
The following will be done during the Screening Visit:

Before any study procedures are done, you will provide your informed consent.

WHAT ARE THE RISKS OF THE STUDY?
As a result of your participation in this study, you are at risk for the following side effects. You should 
discuss these with the study doctor and your regular health care provider if you choose.
Study Drug Risks 
Because MW151 HCl is considered “investigational,” complete information about the safety of MW151 
HCl is not yet available. At this stage of development, there is no evidence that the drug is unsafe or has 
specific risks when given to people; however, there could be risks, including death, that are as yet 
unidentified. MW151 HCl is made by chemical synthesis and many precautions have been taken in the 
making of the MW151 HCl to be used in the study. Group 1 received MW151 HCl at a 10 mg dose 
level, and there were no problems at that dose level. However, higher doses have not been tested yet. 
MW151 HCl may cause some, all or none of the following side-effects including nausea and headache 
and there could be risks, including death, that are as yet unidentified. You should discuss these with the

Animals were given oral doses of MW151 HCl for up to 28 days, at multiple levels higher than those 
being studied in this clinical study. In rats, at certain doses tested, some changes were seen under the 
microscope in their testicles and sperm. Some of these changes got worse and did not resolve once the 
drug was stopped. The doses given to these rats were at least 2 times greater than the comparable dose of 
drug you could receive. Additionally, you will only be receiving a single dose. However, for maximum 
safety, Groups 2 – 5 will consist of female subjects only.
In dogs, at doses that are at least 10-times higher than the highest comparable dose you could receive, 
changes in the electrical signals in the heart (electrocardiogram, ECG) were seen. These electrical 
changes can potentially cause changes in the heart rhythm and in some severe cases could prevent your 
heart from pumping sufficient blood and you may be at risk of death. Your heart beat, blood pressure, 
heart rhythm and ECG will be closely monitored during this study, including continuously for the first 4 
hours after you receive the study drug.
In some, but not all studies in petri dishes that tested whether the study drug can damage the 
chromosomes that carry your genetic material (genes), MW151 HCl appeared to cause some damage to 
chromosomes. When a similar test was done in rats and in mice, at doses much higher than comparable 
dose you would be expected to receive, there was no damage to chromosomes seen. Since you receive

only a single dose of MW151 HCl, the risk that your chromosomes become damaged by the study drug, 
is extremely low. Therefore, we believe the risk that the study drug could cause cancer is also extremely 
low. 
Because of the way the drug is thought to work, there could be a potential for MW151 HCl to affect 
your immune response (the way your body fights off infection). None of the animals tested so far has 
shown any bad change in their immune function. Subjects with any present or recent evidence of 
infection or at risk for infection are not eligible for the study. 
If you do not understand what some of these side effects or risks mean, ask the study doctor or the study 
staff to explain them to you. You will be carefully monitored throughout the study by the study doctor 
and study staff. Please report any side effects that you may notice.
Co-Occupancy During Confinement
There is an increased risk of COVID-19 with co-occupancy. For this reason, there will also be a need for 
required additional testing that is explained below.
1. Pre- admission:
a.
Participants are instructed to pay close attention to all COVID precautions, including 
masking, limiting contact with others, limiting travel, and maintaining social distancing.
b. Participants will have a COVID test within 72 hours prior to confinement and repeated 
the day of admission for the confinement period.
c.
Participants will be provided clear instructions regarding confinement expectations.
2. During confinement participants will:
a.
Immediately isolate and report development of new symptoms concerning for COVID 
b. Have a COVID test every 3 days.
c.
Eat and drink only in their assigned rooms.
d. Wear Duke provided mask unless eating, drinking, or sleeping.
e.
Remain at least 6 feet apart when not wearing a mask.
f.
Remain in their room unless scheduled time in the lounge area and only go there with 
their roommate.  Lounge time will be allocated so that participants remain with the same 
group during the confinement period in order to minimize exposure to others.
g. Perform hand hygiene with soap and water or approved hand sanitizer frequently.
h. Wipe down shared high touch surface areas after use – such as the washing machine, 
lounge table, remote control, sink handles, etc.

i.
Be discharged to home for isolation and close observation should their COVID test 
become positive. 
3. Post-confinement:
a.
Participants will require quarantine and COVID testing day 5-7 post-exposure if they are 
exposed late during their confinement period.
 
Allergic Reaction Risks 
There is a risk of allergic reaction. If you have a very serious reaction to MW151 HCl or to the placebo 
you may be at risk of death. Some symptoms of allergic reactions are: rash, difficulty breathing, 
wheezing, sudden drop in blood pressure, swelling around the mouth, throat or eyes, a fast pulse, and 
sweating. Please alert the study doctor and study staff immediately if you have any of these symptoms, 
or any other side effects, during the study. 
Injection Risks/Catheter Insertion Risks/Blood Samples 
Risks associated with drawing blood from your arm include momentary discomfort and/or bruising.  
Infection, excess bleeding, clotting, or fainting are also possible, although unlikely.
A temporary needle (catheter) may be placed into your vein during the study to collect blood. This 
decreases the amount of needle sticks you would receive during these days. The study staff will keep the 
blood draw area clear and clean. Subjects may feel pain or experience bruising at the site where the 
blood is drawn or the catheter is inserted. There is a risk of subjects feeling dizzy or may faint. Infection 
at the site of the blood draw or catheter insertion is possible. Some minor discomfort may be felt when 
blood is drawn from the veins (or the catheter inserted) in your arm. 
You will be required to provide blood samples during the study. Throughout the study up to about 313 
mL (about 10.6 oz) of blood will be taken for scheduled tests. This is less than you would give during a 
regular donation to a blood service agency such as the Red Cross where a typical donation is one pint 
(about 16 oz or 475 mL). Extra blood samples may be taken, if needed, to check on your safety. 
ECGs and Blood Pressure Risks 
Electrocardiograms (ECGs) (electrical tracings of the heartbeat or heart rhythm) will be done during this 
study in which you will have pads placed on different parts of your body. There is no pain or discomfort 
during an ECG; however, removing the pads may cause some irritation to your skin. You may 
experience bruising from the blood pressure cuff.

Reproductive Risks
The effects of the study drug on a developing pregnancy or breastfeeding infant are not known.  Women 
who are pregnant, planning a pregnancy, or breastfeeding are not allowed to participate in studies of the 
drug. 
If you are a woman who could possibly become pregnant (you have not completed menopause, or you 
have not had a hysterectomy and/or both tubes and/or both ovaries removed) and you have a partner 
who is able to father children, a blood pregnancy test will be performed at screening, and it must be 
negative in order to continue.  In women 40 years old and older, blood pregnancy tests sometimes give a 
false positive or indeterminate result and additional testing may be needed.   A urine pregnancy test will 
be performed when you come in for your Study Day 1 visit.  
You and your partner must agree to either abstain completely from vaginal intercourse from the time of 
the screening visit until 1 month after you receive the study drug, or use an effective method of 
contraception for the same length of time.  Effective methods include (a) partner vasectomy, (b) bilateral 
tubal ligation, (c) intrauterine devices (IUDs), (d) hormonal methods (birth control pills, implants, 
injections, patches, vaginal rings, or (e) barrier methods (condoms, diaphragm, cervical cap) with a 
spermicide.   If you are not currently using one of these methods and would still like to participate in the 
study, the study doctor will discuss options with you.   
Because no birth control method is 100% effective, you should notify the study doctor immediately if 
you think there is any chance you are pregnant within 30 days after receiving the study drug.  
General Discomfort Risks 
You will be asked to fast during parts of this study. This may cause you some discomfort. In addition, 
study requirements such as overnight stays at the clinic, dietary restrictions and limitations on caffeine, 
alcohol, and smoking may also cause you some discomfort. You may experience bruising from the 
blood pressure cuff and/or irritation at the site of the patches applied to the skin for the ECG recordings. 
Serious adverse reactions and hospitalization 
Although all possible precautions are taken to prevent serious adverse reactions (side effects), if such an 
event occurs, it may be in your best interest to be admitted to hospital. Depending on the type of 
reaction, we may contact a medical specialist to be primarily responsible for your treatment. We will 
provide assistance to the hospital and doctors looking after you, but all hospital records are confidential 
and for this reason we are asking you to give us, and any emergency medical specialists we contact, 
consent to visit you and have access to your medical records.

1) there is a law that requires disclosure (such as to report child abuse or communicable 
diseases but not for legal proceedings); 
2) you have consented to the disclosure, including for your medical treatment; or 
3) the research information is used for other scientific research, as allowed by federal 
regulations protecting research subjects. 
Disclosure is required, however, for audit or program evaluation requested by the agency that is funding 
this project or for information that is required by the Food and Drug Administration (FDA).
 
You should understand that a Confidentiality Certificate does not prevent you or a member of your 
family from voluntarily releasing information about yourself or your involvement in this research. If you 
want your research information released to an insurer, medical care provider, or any other person not 
connected with the research, you must provide consent to allow the researchers to release it. This means 
that you and your family must also actively protect your own privacy.
Finally, you should understand that the investigator is not prevented from taking steps, including 
reporting to authorities, to prevent serious harm to yourself or others.
The study results will be retained in your research record for at least six years after the study is 
completed. At that time either the research information not already in your medical record may be 
destroyed or information identifying you will be removed from such study results at DUHS.  Any 
research information in your medical record will be kept indefinitely.
Some information collected in research studies is maintained in your medical record. However, for this 
study that information will be inaccessible until the end of the study, unless your physician(s) decide 
that it is necessary for your care. 
This information may be further disclosed by the sponsor of this study.  If disclosed by the sponsor, the 
information is no longer covered by federal privacy regulations.
If this information is disclosed to outside reviewers for audit purposes, it may be further disclosed by 
them and may not be covered by federal privacy regulations.
While the information and data resulting from this study may be presented at scientific meetings or 
published in a scientific journal, your name or other personal information will not be revealed.
Some people or groups who receive your health information might not have to follow the same privacy 
rules. Once your information is shared outside of DUHS, we cannot guarantee that it will remain private.
