Brief summary:
The purpose of this Study is to find out whether an investigational drug is safe and well tolerated. MW189 is being studied as a possible short-term treatment for people with different types of brain injury. MW189 has previously been given to healthy human volunteers as a single dose, and there were no significant problems or bad effects in people who received the Study drug. However, before it can be tested in people with brain injury, it is important to test MW189 in healthy volunteers when given multiple doses.

INTRODUCTION 
 
TT301/MW189 (hereafter called MW189) is a small molecule drug candidate developed as a 
selective suppressor of disease and injury-induced glia proinflammatory cytokine 
overproduction associated with destructive glia inflammation/neuron dysfunction cycles, and 
their long-term neurotoxic effects. MW189 treatment attenuates the stressor-induced rise in 
brain proinflammatory cytokine levels with a downstream improvement in behavior dysfunction 
and synaptic dysfunction markers in multiple animal models of CNS disorders where up-
regulation of proinflammatory molecules is implicated in disease progression. MW189 is being 
developed for the treatment of acute brain injuries such as traumatic brain injury or 
intracerebral hemorrhage. The development program is based on nonclinical evidence that 
MW189 reduces the recruitment of activated microglia, reduces cerebral edema, and improves 
motor skills and neurocognitive outcomes in animal models of neuroinflammatory disorders.  
 
The present study will provide safety and pharmacokinetic (PK) information on multiple 
ascending doses (MAD) of MW189 to support decisions for continued clinical development. This 
study will assess the safety, tolerability, and PK profile of escalating repeated doses of MW189 
in healthy adult participants. The trial design will be a double-blind, placebo-controlled, MAD 
study of MW189 in healthy volunteers. Three 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 and/or specified in the most recent 
amendment of the protocol.  
 
In the study design, 32 healthy male and female volunteers, ages 18-50 years, will be dosed in 
1 of 4 dosing cohorts of 8 subjects each (6 MW189, 2 matched placebo). Subjects will be 
admitted to the Phase 1 unit on the day prior to dosing (Day -1) and will remain in the clinical 
research unit until discharge on Day 8.  Follow-up will be done through a clinic visit at 2 weeks 
and a phone call 4 weeks from end of dosing. 
 
Subjects will receive 2 doses per day for 5 consecutive days. Doses will be given 12 hours 
apart. 
Cohort 1: 0.075 mg/kg MW189 iv bid over 20 minutes (or matched placebo) 
Cohort 2: 0.15 mg/kg MW189 iv bid over 20 minutes (or matched placebo) 
Cohort 3: 0.30 mg/kg MW189 iv bid over 20 minutes (or matched placebo) 
Cohort 4: 0.25 mg/kg MW189 iv bid over 20 minutes (or matched placebo) (added after protocol 
amendment) 
 
Dose levels selected for the MAD study at 0.075 mg/kg, 0.15 mg/kg, 0.25 mg/kg, and 0.30 
mg/kg twice daily for 5 days are based on the safety, PK separation and steady-state PK 
simulations derived from the phase 1a SAD study of MW189. 
For this phase 1b MAD study, dosing will start at the lowest dose in the 1st cohort, then escalate 
in the 2nd cohort, then escalate in the 3rd cohort. Each subject will receive 1 iv dose level of 
MW189 twice daily (bid) on Days 1 through 5, inclusive.  After all subjects in Cohort 1 have 
completed the study through the clinic visit at 2 weeks, data will be collected for the safety 
review. Dosing of Cohort 2 will proceed upon joint recommendation by the Safety and Medical 
Monitors, after reviewing Cohort 1’s safety data including AEs, SAEs, vital signs, safety 
laboratory tests and ECGs. Dosing of Cohort 3 will proceed upon joint recommendation by the 
Safety and Medical Monitors, after reviewing Cohort 2’s safety data including AEs, SAEs, vital

signs, safety laboratory tests and ECGs. Should the safety data warrant, the 2nd or 3rd dose 
levels may be reduced or additional cohorts added in order to generate a comprehensive 
understanding of the clinical dose range, if deemed necessary by the sponsor and 
recommended by the Data Safety Monitoring Board (DSMB). The maximum dose in this study 
will not exceed 0.30 mg/kg bid. Any changes to dosing will be made during the safety review. 
 
Screening will be conducted within 28 days of first dose. 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; physical exam; alcohol and drug screen; Hepatitis B, Hepatitis C, HIV, 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.  
 
Dosing will be twice daily, starting on Day 1 and ending on Day 5 for a total of 5 days with 10 
doses. The second dose of the day will be approximately 12 hours after the morning dose. The 
morning dose each day will be anchored to the initial dose on Day 1 so that the Day 2 morning 
dose will be 24 hours after the Day 1 morning dose and the Day 3 morning dose will be 48 
hours after the Day 1 morning dose, etc. 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 8. Follow-up will be done 
through a clinic visit at 2 weeks and a phone call 4 weeks from end of dosing. The follow-up visit 
will consist of safety lab work, body temperature, ECG, vital signs, concomitant medication review, 
and assessment of adverse events (AEs). The follow-up phone call will include a concomitant 
medication review, and assessment of any safety issues.

STATISTICAL ISSUES 
 
7.1 
GENERAL ANALYSIS CONVENTIONS 
 
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.   
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.  
Baseline is defined as the last assessment prior to first dose of study medication.   
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.  
Statistical analyses will be performed on Linux sever installation of-SAS, Version 9.4.

SAFETY ANALYSES 
 
The safety analysis will be performed using the Safety Population. Safety and tolerability will be 
assessed on the basis of physical examination, neurological examination, vital signs, clinical 
laboratory values, ECG readings, and adverse event (AE) reports. The frequencies of AEs and 
SAE (serious adverse events) will be tabulated by dose as will all other safety measurements.  
For each safety parameter, baseline is defined as the last evaluation before dosing. 
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.   
 
10.1 
ADVERSE EVENT ASSESSMENTS 
 
Adverse events (AEs) will be coded using the Medical Dictionary for Regulatory Activities 
(MedDRA) v21.0 – 5 Level. 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 (TEAE) is an AE, regardless of relationship to study drug, which 
occurs during or after the first dose of study treatment. TEAEs will be summarized by MedDRA 
System Organ Class and Preferred Term.  
 
All AEs will be listed. 
 
 
10.2 
CLINICAL LABORATORY TESTING 
 
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, median, 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. 
 
 
10.3 
VITAL SIGNS 
 
Vital signs (systolic and diastolic blood pressure, heart rate/pulse, body temperature) and 
changes from baseline at each time point will be presented by cohort and treatment group. 
Summary statistics for systolic blood pressure, diastolic blood pressure, temperature, and 
change from baseline (pre-dose) summaries will be presented for each treatment group and 
dose level where applicable. Summary statistics will include number of subjects, mean, median, 
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. 
Criteria for Clinically Notable Vital Sign abnormalities are indicated in Table 2 below.

Descriptive statistics for ECG parameters (e.g. Ventricular Heart Rate, PR interval, QRS 
interval, QTc interval, QTcB, and QTcF interval, RR interval) at baseline and changes from 
baseline at each assessment time point will be presented by cohort and treatment group. 
Baseline will be the median of each subject’s available Day 1 pre-dose results for each 
parameter.  
 
Shift tables summarizing the numbers of subjects shifting from normal pre-dose values to 
abnormal post-dose values will also be presented.  Numeric ECG data will be summarized by 
treatment group and dose level and mean summary tables, including change from baseline will

DETERMINATION OF SAMPLE SIZE 
 
This trial is designed to investigate the safety, tolerability, and PK properties of the drug MW189 
in a dose escalation Phase Ib 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 
MAD study of MW189 in humans, there is no prior experience upon which to base estimates of 
variability for the PK responses to MAD treatment with MW189. 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.
