1. Protocol Synopsis
Title of Study:
Single- and Multiple-Ascending Dose, Safety, Tolerability, and Pharmacokinetic Study with LY3154885 in 
Healthy Subjects
Rationale: 
LY3154885 is a positive allosteric modulator (also called “potentiator”) of the dopamine D1 receptor (D1 PAM)
being developed for the potential treatment of Alzheimer’s dementia and Lewy body dementia, including dementia 
with Lewy bodies and Parkinson’s disease dementia.
LY3154885 has not been administered to humans.  This first-in-human study will investigate the safety, tolerability, 
and pharmacokinetics (PK) of single and multiple doses of LY3154885 in healthy subjects.  The study will also 
investigate the impact of cytochrome P450 (CYP) 3A4 inhibition on the safety, tolerability, and PK of LY3154885, 
and the PK of LY3154885 after a single dose via a tablet or capsule formulation.  The data generated in this study 
will be used to help design subsequent clinical studies.
Objectives/Endpoints:
Objectives
Endpoints

Summary of Study Design:
Study J1Z-MC-HUAA is a Phase 1, single-center study in healthy subjects to be conducted in 4 parts:

Part A will be a subject- and investigator-blind, placebo-controlled, randomized, single-ascending dose, 
3-period crossover study to evaluate safety, tolerability, and PK of LY3154885 in 2 alternating cohorts.

Part B will be a subject- and investigator-blind to LY3154885/placebo, single period, drug-drug interaction 
study with itraconazole.

Part C will be a subject- and investigator-blind, placebo-controlled, randomized, 14-day multiple-ascending 
dose, parallel-group, 3-cohort, single-period study to evaluate safety, tolerability, and PK of LY3154885.

Optional Part D will be an open-label, 3-period, 3-sequence PK study of LY3154885 administered using a 
capsule or tablet formulation.  Part D will also include a pilot food effect evaluation.
Treatment Arms and Planned Duration for an Individual Subject:
Part A:  Subjects will attend a screening visit up to 28 days prior to dosing in Period 1.  Admission to the clinical 
research unit (CRU) will be in the afternoon of Day -2 of the first period and on Day -1 for Periods 2 and 3.  After 
an overnight fast, subjects will receive either LY3154885 or placebo as a single oral dose on Day 1 and will remain 
inpatient for at least 48 hours after dosing (until Day 3), after which they may be discharged at the discretion of the 
investigator.  The washout time between doses for a given subject will be at least 7 days.  A poststudy follow-up 
visit will be conducted at least 7 days after the final dose.
Part B:  Subjects will attend a screening visit up to 28 days before dosing.  Subjects will be admitted to the CRU in 
the afternoon of Day -2 and will receive a single oral dose of LY3154885 or placebo on Day 1 after an overnight 
fast.  There will be a 7-day washout period followed by 10 days of dosing with 200 mg itraconazole (twice daily on 
Day 8 [dose separated by 12 hours], then once daily on Days 9 through 17).  Subjects will receive LY3154885 or 
placebo on Day 14, approximately 1 hour after the dose of itraconazole.
Part C:  Subjects will receive either LY3154885 or placebo as a single oral once-daily dose from Days 1 through 14.  
Study drug will be administered as a single oral dose in the morning under fasted conditions.  Subjects will attend a 
screening visit up to 28 days prior to dosing and will be admitted to the CRU in the afternoon of Day -2.  After the 
initial dose (Day 1), subjects will be required to remain in-house for at least 48 hours after dosing (Day 3) and at the 
discretion of the investigator. Subjects will attend the CRU on Days 4, 5, 6, 9, and 10 on an outpatient basis for 
daily dosing and will be permitted to leave the CRU at the discretion of the investigator.  A poststudy follow-up visit 
will be conducted approximately 7 days after discharge.
Optional Part D:  Subjects will attend a screening visit up to 28 days prior to dosing in Period 1; admission to the 
CRU will be in the afternoon of Day -2 (Periods 1 and 2) and on Day -1 (Period 3).  In Period 1, subjects will 
undergo an overnight fast before receiving a single oral dose of LY3154885 (capsule formulation) on Day 1.  
Subjects will remain inpatient for at least 48 hours after dosing, after which they may be discharged at the discretion 
of the investigator.  Subjects will be re-admitted to the CRU on Day 6, and will undergo an overnight fast before 
receiving a subsequent single oral dose of LY3154885 on Day 8 with the same formulation.  Subjects will be 
discharged on Day 10, at least 48 hours after dosing.

LY3154885
Period 2 will be conducted as described for Period 1; however, LY3154885 will be administered as a tablet 
formulation.  Period 3 will be conducted as described for Period 1; however, subjects will receive a single oral dose 
of LY3154885 (tablet formulation) after administration of a high-fat diet.
Number of Subjects:
For Part A, up to 30 subjects may be enrolled into Cohorts 1 and 2 in order to ensure that approximately 12 subjects 
per cohort (8 LY3154885; 4 placebo) complete this part of the study.
For Part B, up to 15 subjects may be enrolled in order to ensure that approximately 12 subjects (9 LY3154885; 
3 placebo) complete this part of the study.
For Part C, up to 45 subjects may be enrolled in order to ensure that approximately 36 subjects complete this part of 
the study (with approximately 12 subjects [9 LY3154885; 3 placebo] completing each dose level).
For optional Part D, up to 12 subjects may be enrolled in order to ensure that approximately 9 subjects complete this 
part of the study.
Statistical Analysis:
Safety:  Safety parameters that will be assessed include adverse events, clinical laboratory parameters, vital signs, 
and electrocardiogram parameters.  The parameters will be listed and summarized using standard descriptive 
statistics.  Additional analysis will be performed if warranted upon review of the data.
Pharmacokinetics:  Pharmacokinetic parameters including maximum observed drug concentration (Cmax), time to 
Cmax (tmax), and area under the concentration versus time curve (AUC) following single and multiple doses of 
LY3154885 will be calculated using standard noncompartmental methods of analysis.

LY3154885
3. Introduction
Eli Lilly and Company (Lilly) is developing the small molecule, LY3154885, for the potential 
treatment of Alzheimer’s dementia and Lewy body dementia (LBD), including dementia with 
Lewy bodies (DLB) and Parkinson’s disease dementia (PDD).
Lewy body dementia is an umbrella term for a continuum of progressive neurodegenerative 
cognitive disorders that include DLB and PDD.  Parkinson’s disease dementia and DLB are 
pathologically indistinguishable with substantial overlap in clinical phenotype.  Prominent 
clinical features of both include progressive cognitive impairment, recurrent visual 
hallucinations, fluctuations in attention and wakefulness, and parkinsonism (Lippa et al. 2007; 
Thomas et al. 2018).  Diagnostic features of PDD and DLB are also similar, the key distinction 
being timing of dementia onset relative to parkinsonism, if present (McKeith et al. 2005; Emre et 
al. 2007).  Per consensus criteria, PDD is diagnosed when onset of parkinsonism precedes 
dementia, whereas for DLB the onset of dementia should begin no later than 1 year after, and 
often preceding, parkinsonism that is variably present (McKeith et al. 2005).  It is the arbitrarily 
defined sequencing of symptom onset that historically differentiated the 2 conditions.
Lewy body dementias are pathologically characterized by intraneuronal inclusions of Lewy 
bodies throughout subcortical and cortical brain regions, a major component of which is 
misfolded aggregated -synuclein (Beyer et al. 2009).  Lewy body formation and propagation is 
accompanied by progressive neurodegenerative processes, particularly affecting the 
dopaminergic and cholinergic neurons (Harding and Halliday 2001; Klein et al. 2010; 
Colloby et al. 2012).  These neuropathological findings in both PDD and DLB are largely 
indistinguishable and characterized by subcortical, cortical, and limbic Lewy bodies and 
alpha-synuclein pathology.
The cognitive impairments overlap with progressive executive dysfunction, visual-spatial 
abnormalities, and relatively preserved memory early in the course of disease (Lippa et al. 2007).  
Cognitive impairments have the same genetic risk mutations with alpha-synuclein duplications 
and glucocerebrosidase mutations being associated with the development of either PDD or DLB.  
Prodromal features (ie, rapid eye movement sleep behavior disorder and hyposmia) are risk 
factors for both conditions.  The conditions have similar nonmotor features with prominent 
visual hallucinations, fluctuations in arousal, autonomic dysfunction, depression/anxiety, and 
sleep disturbances and share neuroimaging characteristics with overlapping patterns of atrophy, 
glucose utilization, and neurotransmitter changes (cortical cholinergic deficits [Colloby et al. 
2016] and striatal/cortical dopaminergic deficits [Klein et al. 2010]).  Treatment approaches are 
similar, with avoidance of neuroleptics.  Acetylcholine esterase inhibitors are used for the 
treatment of cognitive impairments in both conditions.  Although PDD and DLB have 
traditionally been considered 2 distinct clinical entities, the constellation of supportive 
pathological, clinical, genetic, imaging, and neurochemical data suggest that they fall within a 
spectrum of the same disease (Berg et al. 2014; Gomperts 2016; Friedman 2018; Jellinger 2018; 
Jellinger and Korczyn 2018).  The 2 diseases share similar and overlapping pathologies in 
monoaminergic and acetylcholinergic neurotransmitter deficits that a positive allosteric

modulator (also called “potentiator”) of the dopamine D1 receptor (D1 PAM) may help 
ameliorate.  Critical clinical components of LBDs are also found in Alzheimer’s disease.  For 
example, dopamine insufficiency has been observed in patients with Alzheimer’s disease 
(Mitchell et al. 2011); thus, a meaningful number of patients with Alzheimer’s disease exhibit 
parkinsonian symptoms.  Alzheimer’s disease is an age-related neurodegenerative disease that
results in the slow decline of cognitive and behavioral functions with the characteristic symptom 
of memory loss in patients (Takizawa et al. 2015).  Currently available treatments for 
Alzheimer’s disease have modest benefits for treating cognitive impairment and limited or no 
benefit for other symptoms such as vigilance, depressive symptoms, daytime alertness, and 
apathy.  By potentiating the response to the remaining brain dopamine (or administered 
levodopa), a D1 PAM should improve cognitive performance by enhancing frontal dopaminergic 
neurotransmission, and it is therefore proposed for the treatment of dementia in LBDs (PDD and 
DLB).  In addition to facilitating dopamine neurotransmission, a D1 PAM may be effective in 
improving cognitive dysfunctions in Alzheimer’s disease through activation of cortical neurons, 
markers of synaptic plasticity, and enhanced release of the acetylcholine neurotransmitter.  Other 
effects such as reduced daytime sleepiness, improved mood, and goal-directed behaviors leading 
to reduced apathy (via activation of cortical and striatal D1 receptors) would also be beneficial in 
the LBD and Alzheimer’s disease population.
3.1.
Study Rationale
LY3154885 has not been administered to humans.  This first-in-human study will investigate the 
safety, tolerability, and pharmacokinetics (PK) of single and multiple doses of LY3154885 in 
healthy subjects.  The study will also investigate the impact of cytochrome P450 (CYP) 3A4 
inhibition on the safety, tolerability, and PK of LY3154885 after a single dose via a tablet or 
capsule formulation.  The data generated in this study will be used to help design subsequent 
clinical studies.
3.2.
Background
LY3154885 is a D1 PAM.  By increasing the affinity of the D1 receptor for dopamine, a D1 
PAM should amplify the response to endogenous dopamine, increasing D1 tone when and where 
dopamine is released.  By increasing the affinity of the D1 receptor for dopamine, D1 PAMs 
amplify the response to endogenous dopamine, increasing D1 tone when and where dopamine is 
released (Svensson et al. 2017; Bruns et al. 2018).
This mode of activity is in contrast to direct acting D1 agonists, which activate all D1 receptors 
to which they have access for as long as they are present.  Some D1 agonists also show rapid 
development of tolerance due to constant activation of the D1 receptor.  In contrast, because the 
mechanism of action of a D1 PAM is dependent on endogenous dopamine tone and thus subject 
to normal feedback control, a D1 PAM should have a much lower propensity for overstimulation 
and desensitization.
LY3154885 has demonstrated a favorable safety profile in good laboratory practice (GLP)-
compliant toxicology and safety pharmacology studies to support clinical trials, with 
cardiovascular (CV) and central nervous system (CNS) effects that are transient, monitorable,

5. Study Design
5.1.
Overall Design
This is a Phase 1, single-center study in healthy subjects to be conducted in 4 parts:

Part A will be a subject- and investigator-blind, placebo-controlled, randomized, single-
ascending dose (SAD), 3-period crossover study to evaluate safety, tolerability, and PK 
of LY3154885 in 2 alternating cohorts.

Part B will be a subject- and investigator-blind to LY3154885/placebo, single-period, 
drug-drug interaction study with itraconazole.

Part C will be a subject- and investigator-blind, placebo-controlled, randomized, 14-day 
multiple-ascending dose (MAD), parallel-group, 3-cohort, single-period study to evaluate 
safety, tolerability, and PK of LY3154885.

Optional Part D will be an open-label, 3-period 3-sequence PK study of LY3154885 
administered using a capsule or tablet formulation.  Part D will also include a pilot food 
effect evaluation.
Study governance considerations are described in detail in Appendix 3.
5.1.1. Part A (Single-Ascending Dose)
Part A will be conducted in 2 alternating cohorts (Cohorts 1 and 2), each consisting of 
approximately 12 subjects who will participate in up to 3 study periods. The planned doses of 
LY3154885 to be tested are 15, 45, 100, 200, 400, and 500 mg (see Section 5.5 for details).
Sentinel dosing will be used in Part A of the study.  For all dose levels, LY3154885 and placebo 
will be administered first to 2 subjects (1:1 LY3154885:Placebo) in a blinded manner. These 
subjects will be followed up for 24 hours postdose; if the dose is well tolerated, dosing of the 
remaining 10 subjects in the cohort at the same dose level may begin. 
Each subject in Cohorts 1 and 2 will be randomized to receive 2 single oral doses of LY3154885 
and 1 oral dose of placebo as a capsule formulation over 3 study periods in a crossover fashion.  
For each study period, it is intended that 8 subjects will receive LY3154885 and 4 subjects will 
receive placebo.  
In Period 1, subjects will be admitted to the clinical research unit (CRU) on the afternoon of 
Day -2 for set up of baseline ambulatory blood pressure monitoring (ABPM) (see Section 9.4.4)
and on Day -1 for Periods 2 and 3.  Subjects will undergo an overnight fast (Section 6.3.1) before 
dosing with LY3154885 or placebo as a single oral dose on Day 1 and will remain inpatient for 
at least 48 hours after dosing (until Day 3), after which they may be discharged at the discretion 
of the investigator.  The washout time between doses for a given subject will be at least 7 days.  
A poststudy follow-up visit will be conducted at least 7 days after the final dose.
All available safety data, including AEs, vital signs (blood pressure [BP] and pulse rate [PR]), 
ECGs, and clinical laboratory tests, from all subjects dosed will be assessed prior to escalating to 

J1Z-MC-HUAA(b) Clinical Pharmacology Protocol
Page 29
LY3154885
the next dose level (see Section 10.3.5).  Safety data must include data from at least 2 days from 
a minimum of 6 subjects who received LY3154885. The investigator and sponsor will review 
the data, with the investigator remaining blinded.  If dose escalation is terminated prior to 
reaching Dose 6 because of tolerability issues, previous dose levels may be repeated or 
lower/intermediate dose levels may be tested.
Subjects will provide total urine collections for the 36 hours postdose in each period for 
exploratory metabolism and potential assessment of drug absorption and renal elimination; an 
additional blood sample will be collected to determine serum creatinine measurements.

Abbreviations:  LY = LY3154885; n = number of subjects; PL = placebo.
Each subject will receive 2 doses of LY3154885 and 1 placebo dose.

Illustration of study design for Part A.
5.1.2. Part B (CYP3A4 Inhibition)
Part B will consist of approximately 12 subjects [9 LY3154885; 3 placebo] and will assess the 
effect of itraconazole, a CYP3A4 inhibitor, on the safety, tolerability, and PK of LY3154885.  
The LY3154885 dose to be studied in Part B will be determined based on safety, tolerability, and 
PK data from Part A and will be administered as a capsule formulation.  See Section 5.5 for 
further LY3154885 dose justification.
As detailed in the Schedule of Activities (Section 2), subjects will be admitted to the CRU in the 
afternoon of Day -2 for set up of baseline ABPM (see Section 9.4.4) and will undergo an 
overnight fast (see Section 6.3.1) before receiving a single oral dose of LY3154885 or placebo 
on Day 1.  Subjects may be discharged from the CRU on Day 3 and will be re-admitted on Day 
7.  There will be a 7-day washout period followed by 10 days of dosing with 200 mg 
itraconazole (twice daily on Day 8 [dose separated by 12 hours], then once daily on Days 9
through 17).  See Section 6.3.1 for the fasting requirements for the itraconazole dosing.  Subjects 
will be discharged from the CRU on Day 9 after receiving their dose of itraconazole and will be 
self-dosing on an outpatient basis from Days 10 through 12.  Subjects will be asked to complete 
a diary card to document the actual date and time of dose administration.

Subjects will be re-admitted to the CRU in the evening of Day 12 and will undergo an overnight 
fast (see Section 6.3.1) before receiving a single oral dose of LY3154885 or placebo on Day 14, 
approximately 1 hour after the dose of itraconazole.  Blood sampling for PK purposes 
(LY3154885 and itraconazole) will occur according to the Schedule of Activities in Section 2.  
Subjects will remain in the CRU until discharge on the morning of Day 18, approximately 
24 hours after the final dose of itraconazole.

5.1.3. Part C (Multiple-Ascending Dose)
The decision to conduct Part C will be made after review of safety, tolerability, and PK data 
from Parts A (SAD) and B (CYP3A4 Inhibition).  
Part C will explore up to 3 dose levels in 3 separate cohorts (Cohorts 4 to 6) of healthy subjects.  
Each cohort will consist of approximately 12 subjects (9 LY3154885; 3 placebo) dosed daily for 
14 days with a capsule formulation.
Subjects will participate in a single study period consisting of 14 days of once-daily dosing with 
LY3154885 or placebo; study drug will be administered as a single oral dose in the morning 
under fasted conditions (see Section 6.3.1).  Subjects will be admitted to the CRU on the 
afternoon of Day -2 for set up of baseline ABPM (see Section 9.4.4) and will be required to 
remain in-house for at least 48 hours after dosing (Day 3), and at the discretion of the 
investigator.  As detailed in the Schedule of Activities (Section 2), subjects will attend the CRU 
on Days 4, 5, 6, 9, and 10 on an outpatient basis for daily dosing and will be permitted to leave 
the CRU at the discretion of the investigator.  Pharmacokinetic sampling will be conducted as 
detailed in Section 2.  To assess CV effects and potential accommodation over time, ABPM will

be included on Day -1 (baseline) and on Days 1, 2, 7, 11 and 12, and 14.  A poststudy follow-up 
visit will be conducted approximately 7 days after discharge.
The doses evaluated will be selected based on emerging data from Parts A and B and from the 
lower doses from Part C (see Section 5.5 for details).  If the safety data do not support increasing 
the dose in subsequent cohorts, then a dose may be repeated or lower/intermediate doses may be 
explored.  The PK data obtained during the study may be used to assist in dose-escalation 
decisions, but such data are not required for dose-escalation purposes.  For the safety review 
prior to dose decisions between cohorts, all available safety data (AEs, vital signs, ECGs, and 
laboratory results) to Day 14 from at least 6 subjects taking LY3154885 must be reviewed by the 
sponsor and investigator.  In addition, each cohort (including at least 6 subjects treated with 
LY3154885) will complete dosing to Day 14 prior to the next cohort being admitted to the CRU 
for dosing.

5.1.4. Optional Part D (Pharmacokinetics of Capsule and Tablet 
Formulations and Food Effect)
The decision to conduct Part D will be made after review of safety, tolerability, and PK data 
from Parts A (SAD) and B (CYP3A4 Inhibition).  Part D may be conducted in parallel with 
Part C.
Part D is optional and will assess the PK of single oral doses of LY3154885 in approximately 
9 healthy subjects when administered as a capsule (Period 1), as a tablet (Period 2), and as a 
tablet with a high-fat diet (Period 3).  The dose for Part D will not exceed the highest dose tested 
in Part A (SAD) that was deemed safe and well tolerated.
In Periods 1 and 2, subjects will be admitted to the CRU the afternoon of Day -2 for set up of 
baseline ABPM (see Section 9.4.4); admission for Period 3 will be on Day -1.  In Period 1, 
subjects will undergo an overnight fast (see Section 6.3.1) before receiving a single oral dose of

LY3154885 (capsule formulation) on Day 1.  Subjects will remain inpatient for at least 48 hours 
after dosing, after which they may be discharged at the discretion of the investigator.  Subjects 
will be re-admitted to the CRU on Day 6 and will undergo an overnight fast before receiving a 
subsequent single oral dose of LY3154885 on Day 8 with the same formulation. Subjects will be 
discharged on Day 10, at least 48 hours after dosing.  Re-admission to the CRU will be on 
Day 13, and following an overnight fast, subjects will receive a single oral dose of LY3154885 
on Day 14 with the same formulation.  Final discharge from the CRU will occur on Day 16.  
Pharmacokinetic sampling will be conducted as detailed in the Schedule of Activities 
(Section 2).
Period 2 will be conducted as described for Period 1; however, LY3154885 will be administered 
as a tablet formulation.
Period 3 will be conducted as described for Period 1; however, subjects will receive a single 
oral dose of LY3154885 (tablet formulation) after administration of a high-fat diet (see 
Section 6.3.1). 
The follow-up visit will occur approximately 7 days after final discharge.

6. Study Population
Eligibility of subjects for the study will be based on the results of screening medical history, 
physical examination, vital signs, clinical laboratory tests, and ECG.  The nature of any 
conditions present at the time of the physical examination and any preexisting conditions will be 
documented.
Screening may occur up to 28 days prior to enrollment.  Subjects who are not enrolled within
28 days of screening may be subjected to an additional medical assessment and/or clinical 
measurements to confirm their eligibility.
Prospective approval of protocol deviations to recruitment and enrollment criteria, also known as 
protocol waivers or exemptions, are not permitted.

Severity Rating Scale [C-SSRS]) or develops suicide-related behaviors as 
recorded on the C-SSRS at screening or admission; or are clinically judged by 
the investigator to be at risk for suicide
6.2.1. Rationale for Exclusion of Certain Study Candidates
Exclusion Criteria [8] and [9] prevent conflict of interest in study participants.  Exclusion 
Criteria [10] through [29] and [32] exclude medical conditions, medication intolerance, and 
concomitant medication use that may constitute a risk for the subject and/or may confound the 

J1Z-MC-HUAA(b) Clinical Pharmacology Protocol
Page 41
LY3154885
assessment of study endpoints.  Exclusion Criterion [31] excludes subjects with hearing 
problems in Part B because itraconazole has been associated with transient or permanent 
hearing loss.
6.3.
Lifestyle and/or Dietary Requirements
Throughout the study, subjects may undergo medical assessments and review of compliance with 
requirements before continuing in the study.
6.3.1. Meals and Dietary Restrictions
Part A:  Subjects will be required to fast overnight (at least 8 hours) prior to dosing on Day 1 and 
for at least 4 hours after dosing with LY3154885/placebo, with the exception of water, which
will be freely available after dosing.
Part B:  Subjects will be required to fast overnight (at least 8 hours) prior to each dosing day 
(including itraconazole dosing) and for at least 4 hours after dosing with LY3154885, and 
coadministration of LY3154885 and itraconazole, with the exception of water that will be freely 
available after dosing.  Subjects will also need to fast for approximately 2 hours prior to the 
evening dose of itraconazole on Day 8 and at least 1 hour after dosing, with the exception of 
water, which will be freely available after dosing.
Part C:  Subjects will be required to fast overnight (at least 8 hours) on all dosing days and for at 
least 4 hours after dosing on Days 1, 7, and 14 (intensive PK days), with the exception of water,
which will be freely available after dosing.  On nonintensive PK days, subjects may receive a 
light breakfast approximately 1 hour after dosing.
Part D:  In Periods 1 and 2, subjects will be required to fast overnight (at least 8 hours) prior to 
dosing on Days 1, 8, and 14 and for at least 4 hours after dosing with LY3154885, with the 
exception of water, which will be freely available after dosing.  All other meals will be provided 
according to CRU procedures. In Period 3, following an overnight fast of at least 8 hours, 
subjects will start the high-fat diet (see below) 30 minutes prior to administration of the study 
drug on Days 1, 8, and 14.  Subjects will consume this entire meal in 30 minutes or less; 
however, the study drug will be administered 30 minutes after the start of the meal.  The study 
drug should be administered with approximately 240 mL of room temperature water.  No further 
food will be allowed for at least 4 hours postdose.  Fluids will be restricted from 1 hour prior to 
and until 1 hour after dosing, except for fluid provided with the meal and water required for dose 
administration.
The standardized high-fat, high-calorie meal (fat comprises approximately 50% of total caloric 
content of the meal) should consist of approximately 1000 calories.  No additional food or 
substitute is allowed.  A typical test meal is 2 eggs fried or scrambled in butter, 2 strips of bacon, 
2 slices of toast with butter, 4 ounces of hash brown potatoes, and 8 ounces of whole milk.  This 
test meal derives approximately 150, 250, and 500 to 600 calories from protein, carbohydrates, 
and fat, respectively.

J1Z-MC-HUAA(b) Clinical Pharmacology Protocol

LY3154885
6.3.2. Caffeine, Alcohol, and Tobacco 
Consumption of caffeine- and xanthine-containing products is allowed, provided that the 
subject’s consumption has been consistent for the last 30 days and will remain consistent
throughout the duration of the study.
Subjects will not be permitted to consume alcohol from 48 hours prior to CRU admissions and 
while resident at the CRU. During the study, while not resident at the CRU, the maximum daily 
alcohol intake should not exceed 2 units (see Exclusion Criterion [27], Section 6.2, for 
unit definition).
Smoking, tobacco consumption, or use of any nicotine-replacement therapy is not permitted 
while resident at the CRU. While not resident in the CRU, smoking should not exceed
10 cigarettes per day or equivalent in nicotine use or nicotine substitutes.
6.3.3. Activity
Subjects should avoid strenuous exercise and/or activity for at least 48 hours prior to CRU 
admission and while resident at the CRU.
Subjects should remain upright for at least 2 hours after dosing, with the exception of any 
requirements for protocol procedures (eg, supine for ECGs).
6.3.4. Blood and Plasma Donations
Subjects are not permitted to make blood or plasma donations while participating in the study.
6.4.
Screen Failures
As this study will be conducted in healthy subjects only, individuals who do not meet the criteria 
for participation (ie, screen failure) may not be re-screened, although specific tests such as 
clinical laboratory tests and vital signs/ECGs may be repeated at the discretion of the investigator 
to confirm study eligibility.
Subjects who were eligible for inclusion in previous cohorts but were not randomized for 
nonmedical reasons may be reassessed for eligibility/inclusion in a subsequent cohort.

7. Treatment
7.1.
Treatment Administered
This study involves a comparison of LY3154885 or matching placebo administered orally.  
Table HUAA.7.1 shows the treatment regimens.
Capsules (or tablets for optional Part D) of LY3154885 and/or placebo will be administered 
orally with approximately 240 mL of room temperature water in the morning of each dosing day 
with subjects in a sitting position.  Subjects will not be allowed to lie supine for approximately
2 hours after dosing, unless clinically indicated or for study procedures.

The investigator or designee is responsible for:

explaining the correct use of the investigational product(s) to the subject

verifying that instructions are followed properly

maintaining accurate records of investigational product dispensing and collection

returning all unused medication to Lilly or its designee at the end of the study
Note: In some cases, sites may destroy the material if, during the investigative site selection, the 
evaluator has verified and documented that the site has appropriate facilities and written 
procedures to dispose of clinical materials. 
7.1.1. Packaging and Labeling
The LY3154885 capsules or tablets will be prepared extemporaneously.  The proposed range of 
strengths to be prepared is listed in Table HUAA.7.1.
In Parts A, B and C, for any specific cohort/dosing period, the total number of capsules 
administered will be the same for all subjects, regardless of whether assigned to placebo or 
LY3154885. However, the number of capsules may vary between dosing periods and cohorts to 
maintain the blind.
Instructions for extemporaneous preparation of the study drug will be provided by the sponsor.  
This will be performed by trained personnel (eg, pharmacist) within a facility at the CRU who 
are qualified to perform these types of operations.

J1Z-MC-HUAA(b) Clinical Pharmacology Protocol
Page 44
LY3154885
For LY3154885 capsules, the LY3154885 pure compound with no inactive ingredients will be 
filled into capsules. 
For LY3154885 tablets, the LY3154885 pure compound will be combined with other common 
excipients and compressed into tablets for use in Part D. 
Matching placebo for the LY3154885 capsules will be sourced centrally.  Itraconazole will be 
sourced locally by the site.
The investigational product will be labeled according to the country’s regulatory requirements.
7.2.
Method of Treatment Assignment
In Parts A, B, and C, the randomization table will be prepared by the statistician (or appropriate 
delegate) for the study and provided to the CRU pharmacists or pharmacy staff involved in dose 
preparation.  The allocation and dispensing of the study drug will be fully documented and 
verified by a second person.  Detailed records of the amounts of the study drug received, 
prepared, dispensed, and remaining at the end of the study will be maintained by the 
CRU pharmacist.
7.2.1. Selection and Timing of Doses
The doses will be administered at approximately the same times on each day.  The actual time of 
all dose administrations will be recorded in the subject’s case report form (CRF).  In Part B, for 
the outpatient dosing days for itraconazole, subjects will record the actual time of dose 
administration on a diary card.
Dosing with itraconazole should occur approximately 1 hour before dosing with LY3154885 (or 
placebo) when the 2 drugs are coadministered.
7.3.
Blinding
Parts A, B, and C will be investigator- and subject-blind; Part D will be open-label.  The 
sponsors and site monitors are not blinded.
To preserve the blind, only a minimum number of personnel at the CRU (namely, CRU 
pharmacy staff) will see the randomization table before the study is complete.  Individuals 
involved with study drug preparation will not be involved in any of the clinical aspects of the 
study, including study drug administration and AE assessments.  Blinding will be maintained 
throughout the conduct of the study until after all data are cleaned to an acceptable level of 
quality and the CRF is entry locked.
In case of an emergency, the investigator has the sole responsibility for determining if unblinding 
of a subject’s treatment assignment is warranted for medical management of the event.  The 
subject’s safety must always be the first consideration in making such a determination.  If the 
investigator decides that unblinding is warranted, it is the responsibility of the investigator to 
promptly document the decision and rationale and notify Lilly as soon as possible.
Upon completion of the study, all codes must be returned to Lilly or its designee.

J1Z-MC-HUAA(b) Clinical Pharmacology Protocol
Page 45
LY3154885
7.4.
Dose Modification
Dose levels, sampling schedule, timing of procedures (eg, PK and ECG assessments), and length 
of CRU stay may be adjusted in view of emerging safety or PK data during the study.  Dose 
increments may be changed, a dose level may be repeated, or a lower dose may be administered.  
If a dose reduction is required, the dose level for the following cohort (ie, the cohort following 
the one that received a lower than planned dose) cannot exceed ½ log.  The timing of blood 
samplings may be adjusted, but the number of samples will not exceed what has been planned, 
plus the additional samples.  The duration of the CRU stay or the duration of safety follow-up 
may be increased (eg, if the half-life of LY3154885 is longer than anticipated) but not decreased.  
These changes must be appropriately documented and communicated by the sponsor to the 
investigator.  Because these adjustments to timings or dose levels are allowable changes 
permitted by the protocol, they would not require a protocol amendment.
7.4.1. Dose Decision/Escalation
By nature of being a dose-escalation study, data will be evaluated on an ongoing basis until the 
maximum tolerated dose (MTD) is determined or the highest planned dose is administered.  The 
highest dose level that is tolerated will be designated as the MTD.
Safety data will be the primary criteria for the dose escalation.  In addition, if available at the 
time of the dose-escalation decision, PK results will be used as supporting data.  No dose 
escalation can occur without prior discussion and agreement between the investigator and the 
Lilly study team. See Sections 5.1.1 and 5.1.3 for further details.
Safety data, in particular AEs, SAEs, BP, PR, and adverse laboratory abnormalities, will be 
independently assessed by the investigator and will be considered related to the investigational 
medicinal product, unless there is clear evidence that the event is not related.  
If any of the following scenarios occur, dosing at the current level and further dose escalation 
will be discontinued:
1) a single subject experiences an SAE that is related to LY3154885 administration
2) 2 subjects experience a clinically significant event of persistent tremors that is
deemed to be related to LY3154885 administration 
3) 2 subjects experience clinically significant increases in scheduled vital signs that 
are deemed to be related to LY3154885 administration
4) 2 or more subjects at 1 dose level experience other moderate or severe treatment-
related AEs that impair normal activities and are deemed to be related to 
LY3154885 administration
7.5.
Preparation/Handling/Storage/Accountability
The investigator or designee must confirm that appropriate temperature conditions have been 
maintained, as communicated by the sponsor, during transit for all investigational product 
received and that any discrepancies are reported and resolved before use of the study treatment.

J1Z-MC-HUAA(b) Clinical Pharmacology Protocol
Page 46
LY3154885
Only participants enrolled in the study may receive IMP or study materials, and only authorized 
site staff may supply or administer IMP.  All IMP should be stored in an environmentally 
controlled and monitored (manual or automated) area in accordance with the labeled storage 
conditions with access limited to the investigator and authorized site staff.
The investigator, institution, or the head of the medical institution (where applicable) is 
responsible for study treatment accountability, reconciliation, and record maintenance (such as 
receipt, reconciliation, and final disposition records).
7.6.
Treatment Compliance
The IMP will be administered at the clinical site, and documentation of treatment administration 
will occur at the site.
7.7.
Concomitant Therapy
Subjects on stable concomitant medication at the time of study entry should continue their 
regular, unchanged dose throughout the study.  These permitted medications have been described 
in Exclusion Criterion [25].
In general, concomitant medication should be avoided; however, paracetamol/acetaminophen 
(1g, maximum 3g/24 hours) may be administered at the discretion of the investigator for 
treatment of headaches, etc.  If the need for concomitant medication (other than acetaminophen) 
arises, inclusion or continuation of the subject in the study may be at the discretion of the 
investigator after consultation with a Lilly clinical pharmacologist.  Drugs that are known 
inducers or inhibitors of CYP3A4 are specifically excluded.  Any medication used during the 
course of the study must be documented.
7.8.
Treatment after the End of the Study
This section is not applicable for this study.

J1Z-MC-HUAA(b) Clinical Pharmacology Protocol
Page 47
LY3154885
8. Discontinuation Criteria
8.1.
Discontinuation from Study Treatment
A subject will be discontinued from receiving further doses of IMP if the investigator assesses 
that continuation on IMP may pose a risk to the well-being of the subject in question.  Subjects 
may also be discontinued from the IMP if a clinically significant event (CSE) occurs in the 
opinion of the investigator.  Following the investigator’s determination that CSE criteria have 
been met and the investigator’s judgment of relatedness to the IMP is documented, a decision 
will be made between the investigator and Lilly or its designee regarding subject discontinuation.
Discontinuation of the IMP for abnormal liver tests should be considered by the investigator 
when a subject meets 1 of the following conditions after consultation with the Lilly designated 
medical monitor:

Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) 
>5upper limit of normal (ULN)

ALT or AST >3ULN and total bilirubin level (TBL) >2ULN or 
international normalized ratio >1.5 or

ALT or AST >3ULN with the appearance of fatigue, nausea, vomiting, right 
upper-quadrant pain or tenderness, fever, rash, and/or eosinophilia (>5%)

Alkaline phosphatase (ALP) >3ULN

ALP >2.5ULN and TBL >2ULN

ALP >2.5ULN with the appearance of fatigue, nausea, vomiting, right 
quadrant pain or tenderness, fever, rash, and/or eosinophilia (>5%)
Subjects discontinuing from the treatment prematurely for any reason should complete AE and 
other follow-up procedures per Section 2 of this protocol.
8.1.1. Discontinuation of Inadvertently Enrolled Subjects
If the sponsor or investigator identifies a subject who did not meet enrollment criteria and was 
inadvertently enrolled, a discussion must occur between the Lilly clinical pharmacologist and the 
investigator to determine if the subject may continue in the study.  If both agree it is medically 
appropriate to continue, the investigator must obtain documented approval from the Lilly clinical 
pharmacologist to allow the inadvertently enrolled subject to continue in the study with or 
without continued treatment with investigational product.  
8.2.
Discontinuation from the Study
Subjects will be discontinued in the following circumstances:

Enrollment in any other clinical study involving an investigational product or enrollment 
in any other type of medical research judged not to be scientifically or medically 
compatible with this study

J1Z-MC-HUAA(b) Clinical Pharmacology Protocol
Page 48
LY3154885

Participation in the study needs to be stopped for medical, safety, regulatory, or other 
reasons consistent with applicable laws, regulations, and good clinical practice (GCP)

Investigator Decision
o
the investigator decides that the subject should be discontinued from the study
o
if the subject, for any reason, requires treatment with another therapeutic agent 
that has been demonstrated to be effective for treatment of the study indication, 
discontinuation from the study occurs prior to introduction of the new agent

Subject Decision
o
the subject requests to be withdrawn from the study

If any of the potentially clinically significant vital sign criteria (Table HUAA.8.1) are met 
at 3 consecutive scheduled time points using in-clinic vital sign monitoring on Day 1 
and following study drug dosing, the subject should be discontinued from the study drug.  
The relative value of the potentially clinically significant vital sign criteria is calculated 
by comparing the mean of the 3 supine BP and PR measurements at Time 0 on that day.
Table HUAA.8.1.
Potentially Clinically Significant Vital Sign Criteria
o
For vital sign measurements that meet the criteria for potentially clinically 
significant vital signs (Table HUAA.8.1), action will be left to the discretion of 
the investigator and may include discontinuation of study drug or subject.  Prior to 
subject being discontinued from the study, the investigator should consult with the 
Lilly clinical pharmacologist (CP) or designee.

Subjects will be discontinued from the study if the mean QT interval corrected for 
heart rate using Fridericia’s formula (QTcF) on the ECG is >500 milliseconds or 
there is an absolute change of >60 milliseconds when compared with baseline

8.3.
Subjects Lost to Follow-up
A subject will be considered lost to follow-up if he or she repeatedly fails to return for scheduled 
visits and is unable to be contacted by the study site.  Site personnel are expected to make 
diligent attempts to contact subjects who fail to return for a scheduled visit or were otherwise 
unable to be followed up by the site.

9. Study Assessments and Procedures
Section 2 lists the Schedule of Activities, detailing the study procedures and their timing 
(including tolerance limits for timing).  
The specifications in this protocol for the timing of safety and sample collection are given as 
targets to be achieved within reasonable limits.  Modifications may be made to the time points 
based upon emerging clinical information.  The scheduled time points may be subject to minor 
alterations; however, the actual procedure time has to be correctly recorded in the CRF, 
including samples that are collected outside of the allowable time window.  Failure or being late 
(ie, outside stipulated time allowances) to perform procedures or obtain samples due to 
legitimate clinical issues (eg, equipment technical problems, venous access difficulty, or subject 
defaulting or turning up late on an agreed scheduled procedure) will not be considered as 
protocol deviations but the CRU will still be required to notify the sponsor in writing via a 
file note.
Appendix 2 lists the laboratory tests that will be performed for this study.
Appendix 5 provides a summary of the maximum number and volume of invasive samples, for 
all sampling, during the study.
Unless otherwise stated in the subsections below, all samples collected for specified laboratory 
tests will be destroyed within 60 days of receipt of confirmed test results.  Certain samples may 
be retained for a longer period, if necessary, to comply with applicable laws, regulations, or 
laboratory certification standards.
9.1.
Efficacy Assessments
This section is not applicable for this study.
9.2.
Adverse Events
Investigators are responsible for monitoring the safety of subjects who have entered this study 
and for alerting Lilly or its designee to any event that seems unusual, even if this event may be 
considered an unanticipated benefit to the subject.
The investigator is responsible for the appropriate medical care of subjects during the study.
Investigators must document their review of each laboratory safety report.
The investigator remains responsible for following, through an appropriate health care option, 
AEs that are serious or otherwise medically important, considered related to the investigational 
product or the study, or that caused the subject to discontinue the investigational product before 
completing the study.  The subject should be followed until the event resolves, stabilizes with 
appropriate diagnostic evaluation, or is reasonably explained.  The frequency of follow-up 
evaluations of the AE is left to the discretion of the investigator.
The investigator will record all relevant AE and SAE information in the CRF.  After the 
informed consent form is signed, study site personnel will record, via CRF, the occurrence and

nature of each subject’s preexisting conditions, including clinically significant signs and 
symptoms of the disease under treatment in the study.  Additionally, site personnel will record 
any change in the condition(s) and the occurrence and nature of any AEs.  
The investigator will interpret and document whether or not an AE has a reasonable possibility 
of being related to study treatment or a study procedure, taking into account the disease, 
concomitant treatment, or pathologies.  
A “reasonable possibility” means that there is a potential cause and effect relationship between 
the investigational product and/or study procedure and the AE.
Planned surgeries should not be reported as AEs, unless the underlying medical condition has 
worsened during the course of the study.
If a subject’s IMP is discontinued as a result of an AE, study site personnel must report this to 
Lilly or its designee via CRF.
9.2.1. Serious Adverse Events
An SAE is any AE from this study that results in one of the following:

death

initial or prolonged inpatient hospitalization

a life-threatening experience (that is, immediate risk of dying)

persistent or significant disability/incapacity

congenital anomaly/birth defect

important medical events that may not be immediately life-threatening or result in death 
or hospitalization but may jeopardize the patient or may require intervention to prevent 
one of the other outcomes listed in the definition above
Study site personnel must alert the Lilly CP/clinical research physician (CRP), or designee, of 
any SAE as soon as practically possible.
Additionally, study site personnel must alert Lilly Global Patient Safety, or its designee, of any 
SAE within 24 hours of investigator awareness of the event via a sponsor-approved method.  If 
alerts are issued via telephone, they are to be immediately followed with official notification on 
study-specific SAE forms.  This 24-hour notification requirement refers to the initial SAE 
information and all follow-up SAE information.
Investigators are not obligated to actively seek AEs or SAEs in subjects once they have 
discontinued from and/or completed the study (the subject summary CRF has been completed).  
However, if the investigator learns of any SAE, including a death, at any time after a subject has 
been discharged from the study, and he/she considers the event reasonably possibly related to the 
study treatment or study participation, the investigator must promptly notify Lilly. 

J1Z-MC-HUAA(b) Clinical Pharmacology Protocol
Page 52
LY3154885
Pregnancy (maternal or paternal exposure to IMP) does not meet the definition of an AE.  
However, to fulfill regulatory requirements any pregnancy should be reported following the SAE 
process to collect data on the outcome for both mother and fetus.
9.2.1.1.
Suspected Unexpected Serious Adverse Reactions 
Suspected unexpected serious adverse reactions (SUSARs) are serious events that are not listed 
in the IB and that the investigator reports as related to investigational product or procedure.  Lilly 
has procedures that will be followed for the recording and expedited reporting of SUSARs that 
are consistent with global regulations and the associated detailed guidances.
9.2.2. Complaint Handling
Lilly collects product complaints on investigational products and drug delivery systems used in 
clinical trials in order to ensure the safety of study participants, monitor quality, and to facilitate 
process and product improvements.
Subjects should be instructed to contact the investigator as soon as possible if they have a 
complaint or problem with the investigational product so that the situation can be assessed.
9.3.
Treatment of Overdose
For the purposes of this study, an overdose of LY3154885 is considered any dose higher than the 
dose assigned through randomization.  General supportive medical management will be provided 
at the investigator’s discretion.
9.4.
Safety
9.4.1. Laboratory Tests
For each subject, laboratory tests detailed in Appendix 2 should be conducted according to the 
Schedule of Activities (Section 2). 
With the exception of safety laboratory test results that may unblind the study, Lilly or its 
designee will provide the investigator with the results of laboratory tests analyzed by a central 
vendor, if a central vendor is used for the study.
9.4.2. Vital Signs
For each subject, vital sign measurements should be conducted according to the Schedule of 
Activities (Section 2). Vital signs will comprise BP, PR, and body temperature.
For supine measurements of BP and PR, subjects should be in the supine position for at least 
5 minutes before the procedure.
Unscheduled orthostatic vital signs should be assessed, if possible, during any AE of dizziness or 
posture-induced symptoms.  Additional vital signs may be measured during each study period 
if warranted.

J1Z-MC-HUAA(b) Clinical Pharmacology Protocol
Page 53
LY3154885
For orthostatic measurements of BP and PR, subjects should be supine for at least 5 minutes and 
stand for at least 2 minutes for supine and standing measurements, respectively.  If the subject 
feels unable to stand, supine vital signs only will be recorded.
9.4.3. Electrocardiograms
For each subject, ECGs should be collected according to the Schedule of Activities (Section 2).
Any clinically significant findings from ECGs that result in a diagnosis and that occur after the 
subject receives the first dose of the investigational product should be reported to Lilly or its 
designee as an AE via the CRF.
At screening, early discontinuation, and follow-up, a single ECG will be obtained and does not 
need to be transmitted to the ECG vendor.  The screening ECG will be interpreted by the 
investigator or qualified designee at the site to determine whether the subject meets entry criteria.  
In Parts A, B and D, single ECGs will be collected at all time points.
In Part C, at all time points other than screening, early discontinuation, and follow-up, ECGs will 
be collected in triplicate.
Electrocardiograms should preferably be recorded before collecting any blood samples.  Subjects 
must be supine for approximately 5 minutes before ECG collection and remain supine but awake 
during ECG collection.  Consecutive replicate ECGs will be obtained at approximately 1-minute 
intervals.  Electrocardiograms may be obtained at additional times, when deemed clinically 
necessary.  Collection of more ECG replicates than expected at a particular time point will be 
permitted to ensure high-quality records.
Electrocardiograms will be interpreted by a qualified investigator (physician  or qualified 
designee) at the site as soon after the time of ECG collection as possible, and ideally while the 
subject is still present, to determine whether the subject meets entry criteria at the relevant 
visit(s) and for immediate subject management, should any clinically relevant findings 
be identified.
If a clinically significant quantitative or qualitative change from baseline is identified after 
enrollment, the investigator will assess the subject for symptoms (eg, palpitations, near syncope, 
syncope) to determine whether the subject can continue in the study.  The investigator or 
qualified designee is responsible for determining if any change in subject management is needed 
and must document his/her review of the ECG printed at the time of evaluation from at least 1 of 
the triplicate ECGs from each time point.
Digital ECGs will be electronically transmitted to a central ECG laboratory designated by Lilly.  
The central ECG laboratory will perform a basic quality control check (eg, demographics and 
study details), then store the ECGs in a database.  At a future time, the stored ECG data may be 
overread at the central ECG laboratory for further evaluation of machine-read measurements or 
to meet regulatory requirements. 

J1Z-MC-HUAA(b) Clinical Pharmacology Protocol
Page 54
LY3154885
The machine-read ECG intervals and heart rate may be used for data analysis and report writing 
purposes, unless a cardiologist overread of the ECGs is conducted prior to completion of the 
final study report (in which case, the overread data would be used).
9.4.4. Ambulatory Blood Pressure Monitoring
Ambulatory blood pressure monitoring will be performed in all parts of the study.  The ABPM 
device will be fitted to the subject’s nondominant arm and will record ambulatory BP and PR 
every 30 minutes during awake hours (0700 hours to 2200 hours) and every 60 minutes 
throughout the night (2200 hours to 0700 hours).  All Day -1 recordings are 24 hours and will 
serve as baseline. The recording on dosing days will be initiated approximately 2 hours prior to 
the planned dosing time (baseline value) and will continue according to the Schedule of 
Activities (Section 2).  Subjects will be encouraged to maintain light activity (e.g, walking) and 
keep the same routine during the ABPM study days.  Ambulatory blood pressure monitoring data 
may not be used for subject management or dose escalation decisions.
9.4.5. Neurological Examination 
A directed neurological examination will be performed by the investigator (or designee) at the 
time points specified in the Schedule of Activities (Section 2).  If clinically significant 
abnormalities are noted at these time points, additional examinations should be performed as 
clinically necessary.  Examination procedures may include inspection for tremor, extraocular 
movements, brachial and patellar deep tendon reflexes, finger-nose pointing, and Romberg sign.

9.4.6. Columbia-Suicide Severity Rating Scale (Part C Only)
The C-SSRS (Columbia Lighthouse Project [WWW]) captures the occurrence, severity, and 
frequency of suicide-related thoughts and behaviors during the assessment period.  The scale 
includes suggested questions to solicit the type of information needed to determine if a suicide-
related thought or behavior has occurred.  The C-SSRS will be administered by appropriately 
trained site personnel at the time points specified in the Schedule of Activities (Section 2).  
Subjects with any significant change must be referred to a psychiatrist.

J1Z-MC-HUAA(b) Clinical Pharmacology Protocol
Page 55
LY3154885
If the investigator determines that suicide-related behaviors have occurred, the Lilly Self-Harm 
Supplement Form will be used to collect additional information to allow for a more complete 
assessment of these behaviors.  As noted above, subjects with any clinically significant change, 
as determined by the investigator, must be referred to a psychiatrist.
9.4.7. Exploratory Scales and Questionnaire (Part C Only)
9.4.7.1.
Profile of Mood States Second Edition
The Profile of Mood States Second Edition (POMS-2) (Heuchert and McNair 2012) is a 35-item, 
adjective rating scale and is considered to be a standardized mood-state inventory.  Subjects will 
be instructed to rate each adjective on the basis of how they feel at the present time on a scale 
with 5 response options (scored numerically from 0 to 4, respectively):  “Not at all,” “A little,” 
“Moderately,” “Quite a bit,” and “Extremely.”  The POMS-2 will be completed at the time 
points stipulated in the Schedule of Activities (Section 2).
9.4.7.2.
Physician Withdrawal Checklist
The Penn Physician Withdrawal Checklist (PWC-20) is a 20-item checklist that will be used to 
assess the presence and severity of withdrawal symptoms.  The scale was originally developed to 
assess the severity of withdrawal symptoms in anxiolytic medication discontinuation (Rickels et 
al. 2008).  The PWC-20 is a validated, shortened version of the original 35-item checklist, where 
the 20-items were selected based on their statistical ability to differentiate between placebo and 
LY3154885 (Rickels et al. 1990; Schweizer et al. 1990).  The 20 items assess the subject’s level 
of symptoms on a variety of withdrawal symptoms since last visit.  Each of the 20 items are 
scored as 0 (not present), 1 (mild), 2 (moderate), or 3 (severe).
9.4.8. Safety Monitoring
The Lilly CP and principal investigator (PI) will monitor safety data throughout the course of the 
study. In the event of safety concerns, the Lilly clinical pharmacologist and PI will recommend a 
protocol amendment or termination of the trial and will report to the investigational review board 
(IRB) accordingly. 
Lilly will review SAEs within time frames mandated by company procedures.  The Lilly CP or 
CRP will periodically review the following data:

trends in safety data, such as BP, PR, ECGs, and ABPM

laboratory analytes

adverse events
When appropriate, the Lilly CP will consult with the functionally independent Global Patient 
Safety therapeutic area physician or CRP.
9.4.8.1.
Hepatic Safety
If a study subject experiences elevated ALT ≥3ULN, ALP ≥2ULN, or elevated TBL ≥2
ULN, liver tests (Appendix 4) should be repeated within 3 to 5 days including ALT, AST, ALP, 
TBL, direct bilirubin, gamma-glutamyl transferase, and creatinine kinase to confirm the 

J1Z-MC-HUAA(b) Clinical Pharmacology Protocol

LY3154885
abnormality and to determine if it is increasing or decreasing.  If the abnormality persists or 
worsens, clinical and laboratory monitoring should be initiated by the investigator based on 
consultation with the Lilly CP or CRP.  Monitoring should continue until levels normalize and/or 
are returning to approximate baseline levels. 
Additional safety data should be collected if 1 or more of the following conditions occur: 

elevation of serum ALT to ≥5ULN on 2 or more consecutive blood tests

elevated serum TBL to ≥2ULN (except for cases of known Gilbert’s syndrome)

elevation of serum ALP to ≥2ULN on 2 or more consecutive blood tests 

subject discontinued from treatment due to a hepatic event or abnormality of 
liver tests

hepatic event considered to be an SAE
9.5.
Pharmacokinetics
At the visits and times specified in the Schedule of Activities (Section 2), venous blood samples 
of approximately 3 mL and approximately 2 mL will be collected to determine the plasma 
concentrations of LY3154885 and itraconazole, respectively.  If indicated by emerging data, a
maximum of 3 blood samples per subject may be collected at additional time points during the 
study if warranted and agreed upon between both the investigator and sponsor.  Instructions for 
the collection and handling of blood samples will be provided by the sponsor.  The actual date 
and time (24-hour clock time) of each sampling will be recorded.
Drug concentration information that may unblind the study will not be reported to investigative 
sites or blinded personnel until the study has been unblinded.
Urine samples will be collected for the characterization of renal clearance of LY3154885.  Urine 
samples will be used to determine creatinine and LY3154885 concentration.  Total urine output 
for the appropriate period post LY3154885 administration will be collected, pooled, and 
refrigerated.  At the end of the collection period, the total urine volume will be recorded.  Any 
special instructions for the collection and handling of urine samples will be provided by the 
sponsor.  Exploratory metabolite identification of LY3154885 may be conducted using urine 
samples.  In Part A only, venous blood samples of approximately 3.5 mL each will be collected 
to determine serum creatinine measurements. 
9.5.1. Bioanalysis
Samples will be analyzed at a laboratory approved by the sponsor and stored at a facility 
designated by the sponsor.
Concentrations of LY3154885 and itraconazole and metabolites will be assayed using a validated 
liquid chromatography with tandem mass spectrometry (LC/MS/MS) method.  Samples collected 
from subjects receiving placebo will be retained and only analyzed for LY3154885 if required to 
confirm subject dosing records.

J1Z-MC-HUAA(b) Clinical Pharmacology Protocol
Page 57
LY3154885
Bioanalytical samples collected to measure investigational product concentrations (including 
placebo samples) will be retained for a maximum of 2 years following last subject visit for the 
study.  During this time, samples remaining after the bioanalyses may be used for exploratory 
analyses, such as metabolism and/or protein binding work.
9.6.
Exploratory Pharmacodynamics
9.6.1. Exploratory Cognition Assessments (Part C Only)
The Digital Symbol Substitution Test (DSST) and Hopkins Verbal Learning Test (HVLT) will 
be included in Part C to assess relevant aspects of cognition, vigilance, and working memory that 
may provide a pharmacodynamic signal in healthy volunteers.  The tests will be completed at the 
time points stipulated in the Schedule of Activities (Section 2).

DSST:  The DSST is an assessment of complex scanning and visual tracking.  The screen 
shows a series of 9 numbered symbols that represent a “key.”  The participant is then 
presented with a series of parallel boxes that contain a symbol in the top half of the box 
and must provide a “number” response for the bottom half by referring to the key.  
Numbers are selected using the touch screen.  The participant is given 90 seconds to 
respond to as many symbols as possible.

HVLT:  The HVLT is an easily administered 12-item, 3 learning trial, verbal learning test 
with delayed recall and recognition memory testing.  The test requires recall of a series of 
12 words over 3 learning trials, free recall after a delay, and a recognition trial.
9.7.
Genetics
A blood sample will be collected for pharmacogenetic analysis as specified in the Schedule of 
Activities (Section 2), where local regulations allow.  
Samples will not be used to conduct unspecified disease or population genetic research either 
now or in the future.  Samples will be used to investigate variable exposure or response to 
LY3154885 and to investigate genetic variants thought to play a role in neurodegenerative 
diseases or neurological disorders.  Assessment of variable response may include evaluation of 
AEs or differences in efficacy.  
All samples will be coded with the subject number.  These samples and any data generated can 
be linked back to the subject only by the investigative site personnel.  
Samples will be retained for a maximum of 15 years after the last subject visit, or for a shorter 
period if local regulations and/or ERBs/IRBs impose shorter time limits, for the study at a 
facility selected by Lilly.  This retention period enables use of new technologies, response to 
regulatory questions, and investigation of variable response that may not be observed until later 
in the development of LY3154885 or after LY3154885 is commercially available.  
Molecular technologies are expected to improve during the 15-year storage period and therefore 
cannot be specifically named.  Regardless of technology utilized, data generated will be used 
only for the specific research scope described in this section.

Biomarkers
Biomarker research is performed to address questions of relevance to drug disposition, target 
engagement, pharmacodynamics, mechanism of action, variability of patient response (including 
safety), and clinical outcome.  Sample collection is incorporated into clinical studies to enable 
examination of these questions through measurement of biomolecules including DNA, RNA, 
proteins, lipids, and other cellular elements.
Blood samples for non-pharmacogenetic biomarker research will be collected at the times
specified in the Schedule of Activities (Section 2) where local regulations allow.
Samples will be used for research on the drug target, disease process, variable response to 
LY3154885, mechanism of action of LY3154885, and/or research method, or for validating 
diagnostic tools or assay(s).
All samples will be coded with the subject number.  These samples and any data generated can 
be linked back to the subject only by the investigative site personnel.  
Samples will be retained for a maximum of 15 years after the last subject visit, or for a shorter 
period if local regulations and/or ERBs/IRBs impose shorter time limits, at a facility selected by 
Lilly.  This retention period enables use of new technologies, response to regulatory questions, 
and investigation of variable response that may not be observed until later in the development of 
LY3154885 or after LY3154885 is commercially available.

Statistical Considerations and Data Analysis
10.1. Sample Size Determination
The sample size is customary for Phase 1 studies evaluating safety and PK, and is not powered 
on the basis of statistical hypothesis testing.
Subjects who are randomized but not administered treatment or do not complete all treatment 
periods/doses may be replaced to ensure that enough subjects complete all parts of the study.  
Replacement subjects will be allocated the same treatment/sequence as the dropout subjects.  In 
Part A, a replacement subject’s treatment assignment will follow that of the subject being 
replaced but may not require completion of all study periods.
10.2. Populations for Analyses
10.2.1. Study Participant Disposition
A detailed description of subject disposition will be provided at the end of the study. 
10.2.2. Study Participant Characteristics
The subject’s age, sex, weight, BMI, height, race, or other demographic characteristics will be 
recorded and may be used in the PK and safety analyses as quantitative or classification 
variables.  These data will be summarized using standard descriptive statistics.
10.3. Statistical Analyses
Statistical analysis of this study will be the responsibility of Lilly or its designee.
Pharmacokinetic analyses will be conducted on data from all subjects who receive at least 1 dose 
of the investigational product and have evaluable PK data.  
Safety analyses will be conducted for all enrolled subjects, whether or not they completed all 
protocol requirements.
Additional exploratory analyses of the data will be conducted as deemed appropriate.  Study 
results may be pooled with the results of other studies for population PK analysis purposes to 
avoid issues with post hoc analyses and incomplete disclosures of analyses.  
10.3.1. Safety Analyses
10.3.1.1. Clinical Evaluation of Safety
All investigational product and protocol procedure AEs will be listed, and if the frequency of 
events allows, safety data will be summarized using descriptive methodology.
The incidence of symptoms for each treatment will be presented by severity and by association 
with investigational product as perceived by the investigator.  Symptoms reported to occur prior 
to study enrollment will be distinguished from those reported as new or increased in severity 
during the study.  Each symptom will be classified by the most suitable term from the medical 
regulatory dictionary.

J1Z-MC-HUAA(b) Clinical Pharmacology Protocol
Page 60
LY3154885
The number of investigational product-related SAEs will be reported.
10.3.1.2. Statistical Evaluation of Safety
Safety parameters that will be assessed include AEs, clinical laboratory parameters, vital signs, 
and ECG parameters.  The parameters will be listed and summarized using standard descriptive 
statistics.  Additional analysis will be performed if warranted upon review of the data. All 
planned safety analyses will be detailed in the statistical analysis plan (SAP). 
10.3.2. Pharmacokinetic Analyses
10.3.2.1. Pharmacokinetic Parameter Estimation
Pharmacokinetic parameter estimates for LY3154885 will be calculated by standard 
noncompartmental analysis methods. Parameters for analysis will be maximum observed drug 
concentration (Cmax), time to Cmax (tmax), and area under the concentration versus time curve 
(AUC) of  LY3154885 following single and multiple doses of LY3154885.  Following multiple 
dosing, accumulation ratios based on LY3154885 AUC will be calculated as follows:  AUC 
Day 14 / AUC Day 1 and AUC Day 7 / AUC Day 1.  Other PK parameters such as half-life, 
apparent clearance, and apparent volume of distribution may be reported using 
noncompartmental analysis methods.  
If appropriate data are obtained, renal clearance of LY3154885 will be calculated as the ratio of 
amount excreted/AUC.  This will be compared to the unbound glomerular filtration rate, which is 
estimated using creatinine clearance.
If available, plasma concentration data for itraconazole and its metabolites (if applicable) will be 
summarized or listed in the clinical study report, and the data may subsequently be used for 
exploratory model development. A noncompartmental PK analysis of itraconazole and its 
metabolites may be conducted if deemed valuable to the interpretation of the study results but is 
not required to complete the clinical study report.
10.3.2.2. Pharmacokinetic Statistical Inference
Descriptive statistics of the PK parameters calculated from Parts A, B, C, and D will be 
presented by treatment.  The following details are noted for the respective sections.
Part A:  The PK parameters Cmax and AUC for LY3154885 will be evaluated to estimate the 
dose-exposure proportionality of LY3154885 using a linear-mixed-effect power model.  In this 
model, log-transformed dose will be the independent variable and subject will be a random 
effect.  Both Cmax and AUC will be log-transformed prior to analysis.  The least-squares (LS) 
means for each treatment together with the treatment differences and associated 90% confidence 
intervals (CIs) will be estimated from the model.  These estimates will be back-transformed to 
present geometric means, the ratios of geometric means, and the corresponding 90% CIs.
Part B:  The PK parameters Cmax and AUC for LY3154885 when administered alone and with 
itraconazole will be compared using an analysis of variance (ANOVA) model.  The parameters 
will be log-transformed prior to analysis.  The model will include a fixed-effect for the treatment 
(LY + itraconazole : LY) and a random effect for subject.  The LS means for each treatment, the 

J1Z-MC-HUAA(b) Clinical Pharmacology Protocol
Page 61
LY3154885
difference between the treatment LS means (LY3154885 + itraconazole – LY3154885), and the 
associated 90% CIs will be estimated from the ANOVA model and back-transformed from the 
log scale to provide estimates of the geometric means, geometric mean ratio, and corresponding 
90% CIs.  The tmax of LY3154885 for both treatments will be analyzed using a Wilcoxon 
signed-rank test.  An estimate of the median difference and 90% CI will be calculated.
Part C:  The plasma PK parameters Cmax and AUC for LY3154885 obtained on Day 14 will be 
evaluated to estimate the dose-exposure proportionality of LY3154885 using a linear-mixed-
effect power model.  For details of the model, see Part A above.
Plasma concentrations of LY3154885 will be evaluated graphically and/or descriptively to assess 
the achievement of steady-state, but no formal analysis will be performed for attainment 
of steady-state.
Part D:
Effect of formulation:  The AUC and Cmax for LY3154885 following administration with a 
capsule and tablet formulation in a fasted state will be log transformed and analyzed using a 
mixed effects ANOVA model.  The model will include fixed effects for formulation (capsule :
tablet).  The LS means for each formulation and the 90% CI for the difference in means will be 
estimated from the ANOVA model and back-transformed from the log scale to provide estimates 
of the geometric means and 90% CIs for the ratio of the means.  The tmax of LY3154885
between formulations will be analyzed using a Wilcoxon signed-rank test.  An estimate of the 
median difference and 90% CI will be calculated.
Effect of high-fat diet: The AUC and Cmax for LY3154885 following administration with a 
tablet formulation in the fed state and fasted state will be log transformed and analyzed using a 
mixed-effects ANOVA model.  The model will include fixed effects for food (fed : fasted).  The 
LS means for fed and fasted and the 90% CI for the difference in means will be estimated from 
the ANOVA model and back-transformed from the log scale to provide estimates of the 
geometric means and 90% CIs for the ratio of the means.  The tmax of LY3154885 between fed 
and fasted will be analyzed using a Wilcoxon signed-rank test.  An estimate of the median 
difference and 90% CI will be calculated.
10.3.3. Exploratory Pharmacodynamic Analyses
Endpoints from the DSST and HVLT will be summarized by domain (as appropriate), time, and 
treatment.  Change from baseline may be displayed as appropriate.  
Further details of analyses will be provided in the SAP.
10.3.4. Exploratory Pharmacokinetic/Pharmacodynamic Analyses 
No LY3154885 exposure–response analyses are planned; however, analyses may be conducted 
for exploratory purposes based on review of the data.

10.3.5. Data Review During the Study
Access to safety and tolerability data is scheduled to occur after every dosing session (see 
Sections 5.1.1, 5.1.2, 5.1.3, and 5.1.4 [study design], and 5.5 [dose justification] for further 
details).  Pharmacokinetic data will be reviewed to guide implementation of this study (such 
as adjustment to blood sampling time) and to support dose escalations at the following 
decision points: 

In Part A, LY3154885 PK data (up to 48 hours postdose) from Doses 1 to 3 will be 
reviewed prior to administration of Dose 5

In Part A, LY3154885 PK data (up to 48 hours postdose) from Dose 5 will be reviewed 
prior to administration of Dose 6

In Part B, LY3154885 PK data (up to 96 hours postdose) will be reviewed to inform a 
decision on the conduct of Part C and D

In Part C, LY3154885 PK data (up to 24 hours postdose on Day 15) from the low dose 
(Cohort 4) will be reviewed prior to administration of the high dose (Cohort 6)
The investigator and the Lilly sponsor team will make the determination regarding dose 
escalation based upon their review of the safety and tolerability data and any available PK 
data. Data reviews may be added as deemed appropriate by the sponsor without a 
protocol amendment.
10.3.6. Interim Analyses
No interim analyses are planned for this study.  If an unplanned interim analysis is deemed 
necessary, the Lilly CP/CRP/investigator or designee will consult with the appropriate medical 
director or designee to determine if it is necessary to amend the protocol.

blinding
A procedure in which one or more parties to the study are kept unaware of the treatment 
assignment(s).  Unless otherwise specified, blinding will remain in effect until final 
database lock.
A single-blind study is one in which the investigator and/or his/her staff are aware of the 
treatment but the subject is not, or vice versa, or when the sponsor is aware of the treatment 
but the investigator and/or his/her staff and the subject are not.  A double-blind study is one

1. Protocol Synopsis (Treatment Arms and Planned Duration for an Individual Subject)
Part A:  Subjects will attend a screening visit up to 28 days prior to dosing in Period 1.  
Admission to the clinical research unit (CRU) will be on in the evening afternoon of Day -2 of 
the first period and on Day -1 for Periods 2 and 3.  After an overnight fast, subjects will receive 
either LY3154885 or placebo as a single oral dose on Day 1 and will remain inpatient for at least 
48 hours after dosing (until Day 3), after which they may be discharged at the discretion of the 
investigator.  The washout time between doses for a given subject will be at least 7 days.  A 
poststudy follow-up visit will be conducted at least 7 days after the final dose.
Part B:  Subjects will attend a screening visit up to 28 days before dosing.  Subjects will be 
admitted to the CRU ion the evening afternoon of Day -2 and will receive a single oral dose of 
LY3154885 or placebo on Day 1 after an overnight fast.  There will be a 7-day washout period 
followed by 10 days of dosing with 200 mg itraconazole (twice daily on Day 8 [dose separated 
by 12 hours], then once daily on Days 9 through 17).  Subjects will receive LY3154885 or 
placebo on Day 14, approximately 1 hour after the dose of itraconazole.
Part C:  Subjects will receive either LY3154885 or placebo as a single oral once-daily dose from 
Days 1 through 14.  Study drug will be administered as a single oral dose in the morning under 
fasted conditions.  Subjects will attend a screening visit up to 28 days prior to dosing and will be 
admitted to the CRU ion the evening afternoon of Day -2.  After the initial dose (Day 1), subjects 
will be required to remain in-house for at least 48 hours after dosing (Day 3) and at the discretion 
of the investigator.  Subjects will attend the CRU on Days 4, 5, 6, 9, and 10 on an outpatient 
basis for daily dosing and will be permitted to leave the CRU at the discretion of the investigator.  
A poststudy follow-up visit will be conducted approximately 7 days after discharge.
Optional Part D:  Subjects will attend a screening visit up to 28 days prior to dosing in Period 1; 
admission to the CRU will be ion the evening afternoon of Day -2 (Periods 1 and 2) and on Day -
1 (Period 3).  In Period 1, subjects will undergo an overnight fast before receiving a single oral 
dose of LY3154885 (capsule formulation) on Day 1.  Subjects will remain inpatient for at least 
48 hours after dosing, after which they may be discharged at the discretion of the investigator.  
Subjects will be re-admitted to the CRU on Day 6, and will undergo an overnight fast before 
receiving a subsequent single oral dose of LY3154885 on Day 8 with the same formulation.  
Subjects will be discharged on Day 10, at least 48 hours after dosing.
Period 2 will be conducted as described for Period 1; however, LY3154885 will be administered 
as a tablet formulation.  Period 3 will be conducted as described for Period 1; however, subjects 
will receive a single oral dose of LY3154885 (tablet formulation) after administration of a high-
fat diet.

Section 9.4.4) and on Day -1 for Periods 2 and 3.  Subjects will undergo an overnight fast 
(Section 6.3.1) before dosing with LY3154885 or placebo as a single oral dose on Day 1 and will 
remain inpatient for at least 48 hours after dosing (until Day 3), after which they may be 
discharged at the discretion of the investigator.  The washout time between doses for a given 
subject will be at least 7 days.  A poststudy follow-up visit will be conducted at least 7 days after 
the final dose.
5.1.2. Part B (CYP3A4 Inhibition)
[…]
As detailed in the Schedule of Activities (Section 2), subjects will be admitted to the CRU in the
evening afternoon of Day -2 for set up of baseline ABPM (see Section 9.4.4) and will undergo an 
overnight fast (see Section 6.3.1) before receiving a single oral dose of LY3154885 or placebo 
on Day 1.  Subjects may be discharged from the CRU on Day 3 and will be re-admitted on Day 
7.  There will be a 7-day washout period followed by 10 days of dosing with 200 mg 
itraconazole (twice daily on Day 8 [dose separated by 12 hours], then once daily on Days 9 
through 17).  See Section 6.3.1 for the fasting requirements for the itraconazole dosing.  Subjects 
will be discharged from the CRU on Day 9 after receiving their dose of itraconazole and will be 
self-dosing on an outpatient basis from Days 10 through 12.  Subjects will be asked to complete 
a diary card to document the actual date and time of dose administration.
5.1.3. Part C (Multiple-Ascending Dose)
[…]
Subjects will participate in a single study period consisting of 14 days of once-daily dosing with 
LY3154885 or placebo; study drug will be administered as a single oral dose in the morning 
under fasted conditions (see Section 6.3.1).  Subjects will be admitted to the CRU on the evening
afternoon of Day -2 for set up of baseline ABPM (see Section 9.4.4) and will be required to 
remain in-house for at least 48 hours after dosing (Day 3), and at the discretion of the 
investigator.  As detailed in the Schedule of Activities (Section 2), subjects will attend the CRU 
on Days 4, 5, 6, 9, and 10 on an outpatient basis for daily dosing and will be permitted to leave 
the CRU at the discretion of the investigator.  Pharmacokinetic sampling will be conducted as 
detailed in Section 2.  To assess CV effects and potential accommodation over time, ABPM will 
be included on Day -1 (baseline) and on Days 1, 2, 7, 11 and 12, and 14.  A poststudy follow-up 
visit will be conducted approximately 7 days after discharge.

LY3154885
The doses evaluated will be selected based on emerging data from Parts A and B and from the 
lower doses from Part C (see Section 5.5 for details).  If the safety data do not support increasing 
the dose in subsequent cohorts, then a dose may be repeated or lower/intermediate doses may be 
explored.  The PK data obtained during the study may be used to assist in dose-escalation 
decisions, but such data are not required for dose-escalation purposes.  For the safety review 
prior to dose decisions between cohorts, all available safety data (AEs, vital signs, ECGs, and 
laboratory results) to at leastDay 614 from at least 6 subjects taking LY3154885 must be 
reviewed by the sponsor and investigator.  In addition, each cohort (including at least 6 subjects 
treated with LY3154885) will complete dosing to Day 14 prior to the next cohort being admitted 
to the CRU for dosing.
5.1.4. Optional Part D (Pharmacokinetics of Capsule and Tablet Formulations and Food 
Effect)
[…]
In Periods 1 and 2, subjects will be admitted to the CRU the evening afternoon of Day -2 for set 
up of baseline ABPM (see Section 9.4.4); admission for Period 3 will be on Day -1.  In Period 1, 
subjects will undergo an overnight fast (see Section 6.3.1) before receiving a single oral dose of 
LY3154885 (capsule formulation) on Day 1.  Subjects will remain inpatient for at least 48 hours 
after dosing, after which they may be discharged at the discretion of the investigator.  Subjects 
will be re-admitted to the CRU on Day 6 and will undergo an overnight fast before receiving a 
subsequent single oral dose of LY3154885 on Day 8 with the same formulation.  Subjects will be 
discharged on Day 10, at least 48 hours after dosing.  Re-admission to the CRU will be on 
Day 13, and following an overnight fast, subjects will receive a single oral dose of LY3154885 
on Day 14 with the same formulation.  Final discharge from the CRU will occur on Day 16.  
Pharmacokinetic sampling will be conducted as detailed in the Schedule of Activities 
(Section 2).

8.4.3. Electrocardiograms
[…]
At screening, early discontinuation, and follow-up, a single ECG will be obtained and does not 
need to be transmitted to the ECG vendor.  The screening ECG will be interpreted by the 
investigator or qualified designee at the site to determine whether the subject meets entry criteria.  
In Parts A, B and D, single ECGs will be collected at all time points.
In Parts A and C, at all time points other than screening, early discontinuation, and follow-up, 
ECGs will be collected in triplicate.
