2. Introduction
2.1.
Study Rationale
This study is being conducted to determine the pharmacokinetics (PK), safety, and tolerability of 
lasmiditan in pediatric migraine patients following a single oral dose of lasmiditan.
This study is part of a pediatric (6 to 18 years) clinical program for lasmiditan. The data from 
this study will be used to inform dose selection in subsequent clinical studies intended to provide 
pivotal efficacy and safety data to support use of lasmiditan for acute treatment of migraine in 
children and adolescents.
This study will also include Japanese pediatric patients to facilitate lasmiditan pediatric clinical 
development in Japan.
2.2.
Background
Lasmiditan is being developed as a novel therapy for the acute treatment of migraine.  
Lasmiditan is a high-affinity, centrally penetrant, selective human serotonin 1F (5-HT1F) receptor 
agonist that exerts its therapeutic effects in the treatment of migraine by decreasing neuropeptide 
release and inhibiting pain pathways, including the trigeminal nerve.  Lasmiditan is structurally 
and mechanistically distinct from other approaches for the acute treatment of migraine, such as 
triptans, and lacks the vasoconstrictive effects of triptans that result from 5-HT1B activity.
Across clinical trials in adults, lasmiditan was generally well tolerated and the majority of 
adverse events (AEs) were mild to moderate, with a duration of 1 to 5 hours for the common 
treatment-emergent adverse events (TEAEs).  Lasmiditan use is associated with neurologic 
TEAEs, with the most common being dizziness, paresthesia, somnolence, fatigue, nausea, 
hypoesthesia, and muscle weakness.  In a variety of analyses of Phase 3 data, proportions of 
adult patients reporting TEAEs generally decreased over time.
In the pivotal efficacy trials in adults, doses of 50 mg, 100 mg, and 200 mg were studied. All 
doses were superior to placebo in the primary and key secondary endpoints of pain freedom and 
freedom from most bothersome symptoms.  A consistent dose–response relationship was 
observed, with patients in higher dose groups having a greater likelihood of response across 
multiple efficacy endpoints. Based on these data in adults with migraine, lasmiditan may 
provide therapeutic benefit to children and adolescents from 6 to <18 years of age with migraine.
A population pharmacokinetic (popPK) analysis of adult PK data following oral administration
indicates that lasmiditan is rapidly absorbed with a median time to reach maximum observed 
drug concentration (tmax) of 1.8 hours and is eliminated with a geometric mean value of 5.7 hours 
for terminal half-life.  Over the clinical dose range of 50 to 200 mg, lasmiditan exposure 
generally increases linearly with dose.  The interindividual variability of lasmiditan maximum 
observed drug concentration (Cmax) and area under the concentration-versus-time curve (AUC)
are 43% and 39%, respectively, based on the popPK analysis.  The covariates of body weight, age 
[elderly vs. nonelderly], and population [healthy vs. patient] were statistically significant in the 

H8H-MC-LAHX Clinical Pharmacology Protocol
Page 16
LY573144
popPK model, but the magnitude of these effects was within the PK variability and therefore not 
considered to be clinically relevant over the range of covariate values in the population.
2.3.
Benefit/Risk Assessment
This is an open-label study in which all pediatric patients will receive a single dose of lasmiditan. 
Participants in the United States (US) will have the opportunity to participate in an open-label, 3-
month addendum to this study.
Participants will also have the opportunity to participate in an open-label, 12-month long-term 
safety study (Study H8H-MC-LAHW) when it is available.
As a centrally penetrant and neurally active drug, lasmiditan use is associated with neurologic 
TEAEs, with the most common being dizziness, paresthesia, somnolence, fatigue, nausea, 
hypoesthesia, and muscle weakness.  It is generally well tolerated, and the vast majority of 
events are mild to moderate and self-limiting.
More information about the known and expected benefits, risks, serious adverse events (SAEs),
and reasonably anticipated AEs of lasmiditan may be found in the Investigator’s Brochure (IB).


limits exposure of patients to lasmiditan, compared with repeat dosing

is consistent with the intended use of lasmiditan as a medication that is taken on an “as 
needed” basis for abortive treatment of migraines

is appropriate to assess PK, safety, and tolerability of lasmiditan.
Body Weight Selection
The lower end of the weight range for this study is 15 kg, as only 1% of pediatric subjects who 
are 6 years of age weigh < 15 kg, based on US pediatric growth charts.  Additionally, in Japan, 
<3% of pediatric subjects who are 6 years of age weigh < 15.6 kg (Kato et. al. 2014).
The higher end of the weight range for this study is 55 kg. The body weight evaluated in adults 
ranged from 48 to 115 kg, with limited exposure data in subjects ≤55 kg (lower 5th percentile).  
Therefore, the body weight range of 15 to 55 kg is considered suitable for evaluation in this 
study.  For body weights above 55 kg, the pediatric exposure of lasmiditan is anticipated to be 
similar to that of adults of the same body weight for a given dose.
Pharmacokinetics
This study is designed to characterize the PK of lasmiditan after a single dose of lasmiditan.  
Blood samples will be collected for 24 hours after dosing, which is considered adequate to 
characterize the PK profile in pediatric patients.  The plasma concentration of lasmiditan is an 
objective measurement; therefore, the open-label design is appropriate for this evaluation.
Japanese Patients
Data from Japanese pediatric patients will be used to inform subsequent clinical studies in 
Japanese patients.
4.3.
Justification for Dose
The planned doses for this study are 100 mg for patients who are 15 to ≤40 kg and 200 mg for 
patients who are >40 to ≤55 kg.
Efficacy and Safety Data
Efficacy and safety data in adults support the use of 50 mg, 100 mg, and 200 mg of lasmiditan 
for the acute treatment of migraine.  Although lower doses were statistically superior to placebo 
on pain freedom at 2 hours, the proportion of patients achieving pain freedom at 2 hours after a 

H8H-MC-LAHX Clinical Pharmacology Protocol
Page 20
LY573144
migraine attack in adult Phase 3 studies was numerically highest for the 200-mg dose.  It is 
important to assess pediatric dose(s) predicted to achieve exposures comparable to adult 200-mg 
exposure, because demonstrating efficacy in pediatric migraine studies has been challenging, in 
part because of the high placebo rates reported in these studies (Evers 2006; Fernandes 2008).
Although 200 mg was the highest dose tested in the Phase 3 migraine program, lasmiditan was 
generally well tolerated in adults, including Japanese adults, up to 400 mg in Phase 1 and 2 
studies.  Also, the margin of safety for the 200-mg dose is estimated to be approximately 3 times, 
based on the ratio of the observed no-observed-adverse-effect-level exposure from the juvenile 
toxicology study to the estimated human exposure at 200 mg.
Dose Levels and Weight Ranges
The planned dose levels and weight ranges are supported by model-based simulations of 
pediatric exposures.  A popPK model was developed using PK data following oral dosing in 
adult patients pooled from multiple Phase 1 studies.  In the model, the effect of body weight on 
apparent total body clearance and volume of distribution resulted in lower lasmiditan exposure in 
heavier patients relative to lighter patients.  Model-based simulations were subsequently 
performed to predict lasmiditan exposures in pediatric patients at 5-kg body weight increments 
(Figure LAHX.1).
The maximum observed drug concentration (Cmax) was considered the primary exposure 
measure used to guide dose selection, as it is expected to be a more relevant response for acute 
treatment.  For pediatric patients (15 to ≤40 kg) receiving 100 mg, the predicted ratio of mean 
Cmax ranged from 0.68 for 40 kg to 1.19 for 15 kg, relative to that of adults receiving 200 mg.  
For pediatric patients (>40 kg to ≤55 kg) receiving 200 mg, the predicted ratio of mean peak 
exposure Cmax ranged from 1.22 for 55 kg to 1.37 for 45 kg, relative to that of adults receiving 
200 mg.
Therefore, the proposed dosing regimen should provide exposures in pediatric patients, 
comparable to the predicted range of adult 200-mg exposures.  PK exposure data will be 
reviewed during the study.  The dose may be adjusted, if lasmiditan exposure is substantially 
different from PK predictions.

5.2.1. Rationale for Exclusion of Certain Study Candidates
Criteria [11] through [20] exclude medical conditions, [21] through [28] exclude concomitant 
medication, substances of abuse, and medical history that may confound the assessment of study 
endpoints, [29] through [31] exclude concurrent clinical trial experience, and [33] and [34] 
prevent conflict of interest in study participants.
5.3.
Lifestyle and/or Dietary Considerations
Throughout the study, patients may undergo medical assessments and review of compliance with 
requirements before continuing in the study.
5.3.1. Meals and Dietary Restrictions
Patients will:

fast overnight prior to the day of dosing with the exception of a light breakfast, such as
cereal with fat-free milk or toast or white rice, 2 hours prior to the time of dosing

abstain from water 1 hour before and after dosing, except for up to 240 mL of water 
given with the dose

fast until approximately 2 hours after dosing, at which time a meal will be served.
5.3.2. Caffeine, Alcohol, and Tobacco
From approximately 48 hours prior to dosing, and up to 24 hours after dosing, patients are not 
allowed to:

consume xanthine- or caffeine-containing food and drink
Examples - cola, chocolate drinks, tea, coffee, and energy drinks containing 
methylxanthine (caffeine, theophylline, or theobromine)

consume alcoholic beverages

use tobacco products.
Limits may be adjusted to meet local requirements if local requirements are more stringent.
5.4.
Screen Failures
At Visit 2, inclusion and exclusion criteria will be reviewed prior to the first dose of 
investigational product.
Screen failures are defined as patients who consent to participate in the study but do not meet the 
enrollment criteria and do not receive any dose of investigational product.
Based on the clinical judgment of the investigator, patients who fail to qualify at enrollment may 
be rescreened at a later date.  Only 1 rescreening visit is permitted.
If rescreening is performed, the parent or guardian and the patient must sign a new assent and 
ICF, and the patient will be assigned a new identification number.

H8H-MC-LAHX Clinical Pharmacology Protocol
Page 27
LY573144
If changes in circumstances have allowed a patient to be rescreened, a complete screening visit 
must be repeated. However, if the rescreen visit is within 30 days from the original screening 
visit and it was a result of only specific out-of-range value/findings, then only those assessments 
should be repeated and not the entire laboratory panel.
A minimal set of screen failure information is required to ensure transparent reporting of screen 
failure participants to meet the Consolidated Standards of Reporting Trials (CONSORT) 
publishing requirements and to respond to queries from regulatory authorities.  Minimal 
information includes demography, screen failure details, eligibility criteria, and any SAE.

6. Treatment
6.1.
Treatment Administered
Lasmiditan 50-mg and 100-mg tablets will be used in this study, to achieve a single total dose of 
either 100 mg or 200 mg (Table LAHX.3).  The investigator will decide which tablet strength to 
administer to achieve the appropriate dose based on the patient’s ability to swallow and patient’s 
preference.
Lasmiditan will be administered orally, on Day 1, in a sitting position.  The actual time of the 
dose administered will be recorded in the patient’s case report form (CRF).
Patients should not lie supine for 2 hours after dosing, unless clinically indicated or for study 
procedures.

LY573144
6.2.
Preparation/Handling/Storage/Accountability
The investigator or designee must confirm all investigational product was received in good 
condition, and any discrepancies are reported and resolved before use of the study drug.
Only patients enrolled in the study may receive investigational product or study materials, and 
only authorized site staff may supply or administer investigational product.  All investigational 
product should be stored in a secure, 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).
6.3.
Measures to Minimize Bias: Randomization and Blinding
This is an open-label study. Patients who meet all criteria for enrollment at Visit 2 will receive a
dose of lasmiditan 100 mg or 200 mg, according to their body weight, as shown in 
Table LAHX.3.
6.4.
Treatment Compliance
The investigational product will be administered at the clinical site, and documentation of 
treatment administration will occur at the site.
6.5.
Concomitant Therapy
For patients taking preventive medication for migraine, treatment regimen must be stable for at 
least 3 months prior to Visit 1.
This study will be conducted during a migraine-free period; therefore concomitant acute 
medications for migraine or migraine symptoms on the day of Visit 1 are not allowed, with the 
exception of acetaminophen, which may be administered at the discretion of the investigator, 
according to label recommendations.
A topical anesthetic cream may be used by the investigator to reduce discomfort associated with 
cannula/needle insertion.
If the need for concomitant medication other than acetaminophen or topical anesthetic arises, 
inclusion or continuation of the patient may be at the discretion of the investigator after 
consultation with Lilly medical. All concomitant medications, whether prescription or over the 
counter, used at baseline and/or during the course of the study, must be recorded on the 
appropriate Concomitant Medication CRF.
6.6.
Dose Modification
The planned dose is 100 mg and 200 mg in pediatric patients with body weight ≥15 kg to ≤40 kg 
and >40 kg to ≤55 kg, respectively.  Safety and PK data will be reviewed on an ongoing basis.

H8H-MC-LAHX Clinical Pharmacology Protocol

7. Discontinuation of Study Treatment and Participant 
Discontinuation and Withdrawal
7.1.
Discontinuation from Study Treatment
This is a single-dose study.  If a patient discontinues after receiving the single dose of lasmiditan, 
early discontinuation procedures will be completed per the Schedule of Activities of this 
protocol.
7.2.
Participant Discontinuation and Withdrawal from the Study
Patients 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.

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 patient should be discontinued from the study.
o
if the patient, 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.

Patient Decision
o
the patient requests to be withdrawn from the study, or
o
the parent or patient’s guardian requests that the patient be withdrawn from the 
study.
Participants discontinuing from the study prematurely for any reason should complete AE and 
other safety follow-up per Section 1.3 (Schedule of Activities), Section 8.3 (Adverse Events 
and Serious Adverse Events), and Section 8.2 (Safety Assessments) of this protocol.
7.2.1. Discontinuation of Inadvertently Enrolled Patients
If the sponsor or investigator identifies a patient who did not meet enrollment criteria and was 
inadvertently enrolled, a discussion must occur between Lilly Medical and the investigator to 
determine if the patient may continue in the study.  If both agree it is medically appropriate to 
continue, the investigator must obtain documented approval from Lilly Medical to allow the 
inadvertently enrolled patient to continue in the study with or without treatment with 
investigational product.
Safety follow-up is as outlined in Section 1.3 (Schedule of Activities), Section 8.3 (Adverse 
Events and Serious Adverse Events), and Section 8.2 (Safety Assessments) of this protocol.

H8H-MC-LAHX Clinical Pharmacology Protocol

7.3.
Patients Lost to Follow-Up
A patient 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 patients who fail to return for a scheduled visit or were otherwise 
unable to be followed up by the site.

8. Study Assessments and Procedures
The Schedule of Activities details the study procedures and their timing (including tolerance 
limits for timing).
Appendix 2 lists the laboratory tests that will be performed for this study.  A separate table in 
this section provides a summary of the maximum number and volume of invasive samples, for
all sampling, during the study.
Unless otherwise stated in 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.
8.1.
Efficacy Assessments
This section is not applicable to this study.
8.2.
Safety Assessments
The Lilly clinical pharmacologist or Clinical Research Physician (CRP)/scientist will monitor 
safety data throughout the course of the study.
8.2.1. Physical Examination
For each patient, a complete physical examination (excluding pelvic and rectal examinations) 
will be performed according to the Schedule of Activities.  A complete physical examination 
may be repeated at the investigator’s discretion at any time a patient presents with physical 
complaints.  A complete physical examination will include, at a minimum, assessments of the 
cardiovascular, respiratory, gastrointestinal, and neurological systems.
8.2.2. Vital Signs
For each patient, vital sign measurements should be conducted according to the Schedule of 
Activities.
Vital signs will consist of 1 pulse rate, 1 temperature, and 3 blood pressure (BP) measurements. 
Three consecutive BP readings will be recorded at intervals of at least 1 minute.  Where 
applicable, the last triplicate vital sign can be used as the supine/semi-recumbent vital sign for 
the calculation of orthostatic changes.
Blood pressure and pulse rate measurements:

will be taken when the patient is in a supine position

should be preceded by at least 5 minutes of rest for the patient in a quiet setting without 
distractions (for example, television, cell phones)

will be collected using the appropriate size pediatric BP cuffs

will be assessed with a completely automated device
o
Manual techniques will be used only if an automated device is not available.

H8H-MC-LAHX Clinical Pharmacology Protocol
Page 34
LY573144
When orthostatic measurements are required, patients should be supine for at least 5 minutes and 
stand for at least 2 minutes. If the patient feels unable to stand, supine vital signs only will be 
recorded. 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.
Any clinically significant findings from vital sign measurements that result in a diagnosis should 
be reported to Lilly or its designee as an AE via electronic case report form (eCRF).
Any abnormal finding for vital signs at 24 hours postdose will need to be repeated at follow-up 
to check if it has returned to baseline.
8.2.3. Electrocardiograms
For each patient, a single12-lead digital ECG will be collected according to the Schedule of 
Activities.  Electrocardiograms may be obtained at additional times, when deemed clinically 
necessary.  Electrocardiograms must be recorded before collecting any blood samples.
Patients must be in supine position for at least 5 minutes before ECG collection and remain 
supine, but awake during ECG collection.
Electrocardiograms will be interpreted by a qualified physician (the investigator or qualified 
designee) at the site as soon after the time of ECG collection as possible, and ideally while the 
patient is still present for immediate patient management, should any clinically relevant findings 
be identified.
Digital ECGs will be electronically transmitted to a central ECG laboratory designated by Lilly.  
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.
Any clinically significant findings from ECGs that result in a diagnosis should be reported to 
Lilly or its designee as an AE via eCRF.
Any abnormal finding for ECGs at 24 hours postdose will need to be repeated at follow-up to 
check if it has returned to baseline.
8.2.4. Clinical Safety Laboratory Assessments
For each patient, laboratory tests detailed in Appendix 2 should be conducted according to the 
Schedule of Activities.  Use of local anesthetics (for example, EMLA cream) consistent with 
local prescribing information is permitted during the study visit to ease discomfort associated 
with venipunctures.
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 clinical trial.
Alkaline phosphatase laboratory results may be out of the normal range in pediatric patients 
because of normal bone growth processes, and collection of a blood sample for bone ALP may 
be requested by the sponsor as a reflex test if the ALP result is high.

H8H-MC-LAHX Clinical Pharmacology Protocol
Page 35
LY573144
Any clinically significant findings from laboratory tests that result in a diagnosis and that occur 
after the patient receives the first dose of investigational product should be reported to Lilly or its 
designee as an AE via CRF.
Investigators must document their review of each laboratory safety report.
8.2.4.1.
Hepatic Safety Monitoring
If a study patient experiences elevated ALT ≥3x ULN, ALP ≥2x ULN, or elevated TBL ≥2x
ULN, liver tests (Appendix 3) should be repeated within 3 to 5 days including ALT, AST, ALP, 
TBL, direct bilirubin, gamma-glutamyl transferase (GGT), and creatine kinase to confirm the 
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 CRP/CRS.  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 ≥5x ULN on 2 or more consecutive blood tests

elevated serum TBL to ≥2x ULN (except for cases of known Gilbert’s syndrome)

elevation of serum ALP to ≥2x ULN on 2 or more consecutive blood tests

patient discontinued from treatment because of a hepatic event or abnormality of 
liver tests

hepatic event considered to be an SAE.
8.2.5. Suicidal Ideation and Behavior Risk Monitoring
8.2.5.1.
C-SSRS
Columbia-Suicide Severity Rating Scale (C-SSRS) is a scale that captures the occurrence, 
severity, and frequency of suicidal ideation and behavior during the assessment period via a 
questionnaire.  The scale was developed by the National Institute of Mental Health (NIMH) trial 
group (TASA) for the purpose of being counterpart to the Columbia Classification Algorithm of 
Suicide Assessment (C-CASA) categorization of suicidal events.
Suicidality will be assessed by the children’s version of the C-SSRS (Posner et al. 2011).  The 
C-SSRS scale includes suggested questions to solicit information needed to determine if a 
suicide-related thought or behavior occurred during the assessment period.
The Self-Harm Supplement should be completed every time the patient is assessed by C-SSRS.  
If there are positive findings on the Self-Harm Supplement, then the Lilly Self-Harm Follow-Up 
form will be used to collect additional information to allow for a more complete assessment of 
these behaviors.
The C-SSRS and a corresponding Self-Harm Supplement Form will be used for assessment of 
the patient according to the Schedule of Activities by appropriately trained site personnel.

H8H-MC-LAHX Clinical Pharmacology Protocol
Page 36
LY573144
Before using the C-SSRS, study site personnel will question the patient about any change in the 
preexisting condition(s) and the occurrence and nature of any AEs.
Nonserious AEs obtained through the questionnaire are recorded and analyzed separately.
Only SAEs and AEs leading to discontinuation elicited through the C-SSRS are to be recorded as 
AEs via the CRF.  Serious adverse events must be reported to Lilly or its designee within 24 
hours as SAEs.
8.2.5.2.
Columbia-Suicide Severity Rating Scale – Child Version
The C-SSRS captures the occurrence, severity, and frequency of suicidal ideation and/or 
behavior during the assessment period.  A children’s version of the C-SSRS will be completed 
for all patients.  The scale includes suggested questions to solicit the type of information needed 
to determine if suicidal ideation and/or behavior occurred.  The C-SSRS is administered by 
qualified site personnel.  The tool was developed by the National Institute of Mental Health trial 
group for the purpose of being a counterpart to the Columbia Classification Algorithm of Suicide 
Assessment categorization of suicidal events.  For this study, the scale has been adapted (with 
permission from the scale authors) to include only the portion of the scale that captures the 
occurrence of the 11 preferred ideation and behavior categories.
The nonleading AE collection should occur prior to the collection of the C-SSRS.  If a 
suicide-related event is discovered during the C-SSRS, but was not captured during the 
nonleading AE collection, sites should not change the AE form.  If an event is serious or leads to 
discontinuation, this is an exception where the SAE and/or AE leading to discontinuation should 
be included on the AE form and the process for reporting SAEs should be followed.
8.2.5.3.
Self-Harm and Follow-up Supplement Forms
The Self-Harm Supplement Form is an administrative form to denote the presence of any 
reported self-harm events and is used to trigger a Self-Harm Follow-Up form in the data capture 
system.  The Self-Harm Follow-Up form is a series of questions that provides a more detailed 
description of the behavior.
As part of the C-SSRS, the Self-Harm Follow-Up form will be completed for each event if the 
patient reports 1 or more self-harm events.
8.2.6. Cognition
Cognition will be assessed by the Cogstate Pediatric Brief Battery (2018 Cogstate Ltd).  This 
is a brief 15- to 18-minute computerized cognitive assessment that measures processing speed, 
attention, visual learning, and working memory.
This battery of cognitive assessments was selected because the assessments are brief, resistant to 
practice effects, culture and language neutral, and have well-established reliability and validity 
for the repeated assessment of cognitive function in children (Mollica et al. 2005).  Evidence 
supports its use in children with chronic pain (Bredlau et al. 2015) and in other indications such 
as mild traumatic brain injury, schizophrenia, and acquired immunodeficiency syndrome–
dementia complex (Maruff et al. 2009).

H8H-MC-LAHX Clinical Pharmacology Protocol

8.2.7. Height and Weight
Height and weight will be assessed according to the Schedule of Activities.

Height will be measured using a stadiometer and measured in triplicate.

Weight must be measured once, and recorded to 1 decimal place without rounding.

Instruments used for measuring height and weight should be appropriately and regularly 
calibrated.

All measurements of height and weight should be taken without shoes and after the 
removal of any heavy personal items (that is, large jewelry, wallets, coats, etc.).
8.2.8. Puberty and Menstrual Status
Pubertal status, including menstrual history, will be determined by the investigator at the 
screening visit based on an interview with the patient and the patient’s guardian, and results of 
blood hormone levels.   
8.2.9. Targeted Neurological Examination
A targeted neurological examination will be performed at the visits and times specified in the 
Schedule of Activities.

Adverse Events and Serious Adverse Events
Investigators are responsible for monitoring the safety of patients 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 patient.
The investigator is responsible for the appropriate medical care of patients 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 patient to discontinue before completing the study.  The 
patient should be followed up 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.
After the ICF and patient assent form are signed, study site personnel will record, via CRF, the 
occurrence and nature of each patient’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, study device, 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.
8.3.1. Serious Adverse Events
An SAE is any AE from this study that results in 1 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.

H8H-MC-LAHX Clinical Pharmacology Protocol
Page 39
LY573144
All AEs occurring after signing the ICF are recorded in the CRF and assessed for serious criteria.  
The SAE reporting to the sponsor begins after the participant has signed the ICF and has 
received the investigational product.  However, if an SAE occurs after signing the ICF, but prior 
to receiving the investigational product, the SAE should be reported to the sponsor according to 
SAE reporting requirements and timelines (see Section 8.3.3) if it is considered reasonably 
possibly related to study procedure.
Study site personnel must alert Lilly 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.  Participants with a serious hepatic AE should have additional data collected using 
the CRF.
Pregnancy (during maternal or paternal exposure to investigational product) 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.
Investigators are not obligated to actively seek AEs or SAEs in subjects once they have 
discontinued and/or completed the study (the participant disposition 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 or she considers the event reasonably possibly related to 
the study treatment or study participation, the investigator must promptly notify Lilly.
8.3.2. 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 identifies as related to investigational product or procedure.  
United States 21 CFR 312.32 and European Union Clinical Trial Directive 2001/20/EC and the 
associated detailed guidances or national regulatory requirements in participating countries 
require the reporting of SUSARs.  Lilly has procedures that will be followed for the 
identification, recording, and expedited reporting of SUSARs that are consistent with global 
regulations and the associated detailed guidances.
8.3.3.
Time Period and Frequency for Collecting AE and SAE 
Information
All AEs and SAEs will be collected from the signing of the ICF until the follow-up visit at the 
time points specified in the Schedule of Activities (Section 1.3).
Medical occurrences that begin before the start of study intervention but after obtaining informed 
consent will be recorded on the Medical History/Current Medical Conditions section of the CRF 
and not on the AE section.
All SAEs will be recorded and reported to the sponsor or designee immediately, and under no 
circumstance should this exceed 24 hours. The investigator will submit any updated SAE data to 
the sponsor within 24 hours of data being available.

H8H-MC-LAHX Clinical Pharmacology Protocol
Page 40
LY573144
Investigators are not obligated to actively seek AE or SAE data after conclusion of the study 
participation. However, if the investigator learns of any SAE, including a death, at any time after 
a patient has been discharged from the study, and he/she considers the event to be reasonably 
related to the study intervention or study participation, the investigator must promptly notify the 
sponsor.
8.3.4. Method of Detecting AEs and SAEs
Care will be taken not to introduce bias when detecting AEs and/or SAEs.  Open-ended and 
nonleading verbal questioning of the participant is the preferred method to inquire about AE 
occurrences.
8.3.5.
Follow-Up of AEs and SAEs
After the initial AE/SAE report, the investigator is required to proactively follow up each patient 
at subsequent visits/contacts. All SAEs, and nonserious AEs of special interest (Section 8.3.8),
will be followed up until resolution, stabilization, the event is otherwise explained, or the patient 
is lost to follow-up as defined in Section 7.3.
8.3.6.
Regulatory Reporting Requirements for SAEs

Prompt notification by the investigator of an SAE to the sponsor is essential so that legal 
obligations and ethical responsibilities toward the safety of participants and the safety of 
a study intervention under clinical investigation are met.

The sponsor has a legal responsibility to notify both the local regulatory authority and 
other regulatory agencies about the safety of a study intervention under clinical 
investigation. The sponsor will comply with country-specific regulatory requirements 
relating to safety reporting to the regulatory authority, Institutional Review Boards 
(IRBs)/Independent Ethics Committees (IECs), and investigators.

Investigator safety reports must be prepared for SUSARs according to local regulatory 
requirements and sponsor policy and forwarded to investigators as necessary.

An investigator who receives an investigator safety report describing an SAE or other 
specific safety information (for example, summary or listing of SAEs) from the sponsor 
will review and then file it along with the IB and will notify the IRB/IEC, if appropriate 
according to local requirements.
8.3.7.
Pregnancy
Details of all pregnancies in female participants and, if indicated, female partners of male 
participants will be collected after the start of lasmiditan dosing and until at least 1 month 
following the last dose of lasmiditan.
To fulfill regulatory requirements, any pregnancy should be reported following the SAE process 
to collect data on the outcome for both mother and fetus.
Abnormal pregnancy outcomes, such as the following, are also considered SAEs:

spontaneous abortion

H8H-MC-LAHX Clinical Pharmacology Protocol
Page 41
LY573144

fetal death

stillbirth

congenital anomalies

ectopic pregnancy.
8.3.8.
Safety Topics of Interest
In addition to those identified above, the following safety topics of interest will be monitored:

Cardiovascular safety

Hepatic safety

Neurologic effects, including injuries and accidents secondary to neurologic AEs 

Road traffic accidents

Abuse potential.
8.3.9. Complaint Handling
Lilly collects product complaints on investigational products and drug delivery systems used in 
clinical studies to ensure the safety of study participants, monitor quality, and to facilitate 
process and product improvements.
Participants will be instructed to contact the investigator as soon as possible if he or she has a 
complaint or problem with the investigational product so that the situation can be assessed.
8.4.
Treatment of Overdose
This is a single-dose study.  This section is not applicable for this study.
8.5.
Pharmacokinetics
At the visits and times specified in the Schedule of Activities, venous blood samples of a 
maximum of 2 mL each will be collected to determine the plasma concentrations of lasmiditan. 
An indwelling catheter is recommended for blood collection on Day 1.  Patients who choose to 
go home after the 12-hour assessments will have the catheter removed prior to leaving the site.
Timing of PK samples collected after lasmiditan dosing was determined by applying a 
D-optimality algorithm to the adult popPK model, which was scaled for pediatric population.  
Patient burden and other factors were also taken into consideration.
One additional sample may be collected at an additional time point 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.

H8H-MC-LAHX Clinical Pharmacology Protocol

LY573144
8.5.1. Bioanalysis
Samples will be analyzed at a laboratory approved by the sponsor and stored at a facility 
designated by the sponsor.
Concentrations of lasmiditan will be assayed using a validated liquid chromatography with 
tandem mass spectrometry method.
Bioanalytical samples collected to measure investigational product concentrations will be 
retained for a maximum of 1 year following the last patient visit for the study.

9. Statistical Considerations and Data Analysis
9.1.
Statistical Hypotheses
No inferential statistical analyses are planned for this study.
9.2.
Sample Size Determination
Cohort 1
Approximately 13 patients may be enrolled to obtain at least 11 patients with evaluable PK data
for the primary cohort (body weight between 15 kg and 40 kg, inclusive).  Patients who do not 
have evaluable PK data may be replaced.
From the popPK analysis in adults, the interpatient coefficient of variation (CV) was estimated to 
be 43% for Cmax and 39% for AUC.  Assuming the CV of total variability is not larger than 45%, 
11 pediatric patients will provide at least 80% coverage probability that the 95% confidence 
intervals (CIs) for the geometric mean of these key PK parameters will be within 70% and 140%.  
The CV for apparent total body clearance and apparent central volume of distribution are similar
to those of Cmax and AUC and, therefore, the precision of estimates for these parameters are 
expected to be sufficient (Wang et al. 2012).
Cohort 2
Approximately 8 patients may be enrolled to obtain at least 6 patients with evaluable PK data for 
the secondary cohort (body weight >40 kg and ≤55 kg). This sample size is customary for Phase 
1 studies evaluating PK, safety, and tolerability, and is not powered on the basis of statistical 
hypothesis testing.
Efforts will be made to enroll male and female patients of varying body weights across the 
weight range defined for the primary and secondary cohorts.
9.3.
Populations for Analyses
9.3.1. Patient Disposition
A detailed description of patient disposition will be provided at the end of the study.
9.3.2. Patient Characteristics
For each cohort, age, sex, weight, height, body mass index, race, and other patient demographic 
characteristics will be summarized using descriptive statistics.
Patient characteristics may be summarized by region (Japanese vs. non-Japanese), if appropriate.
9.4.
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 patients who receive a dose of the 
investigational product and have evaluable PK data.

H8H-MC-LAHX Clinical Pharmacology Protocol
Page 44
LY573144
Safety analyses will be conducted for all enrolled patients who receive a dose of the 
investigational product, whether or not they completed all protocol requirements.
Data analyses will be presented by body weight category, age, body surface area, and glomerular 
filtration rate.
Additional exploratory analyses of the data will be conducted as deemed appropriate.
9.4.1. Safety Analyses
Safety analyses will be conducted based on safety data obtained from the screening, PK/safety 
assessment, and follow-up/early discontinuation phases of the study.
9.4.1.1.
Clinical Evaluation of Safety
All investigational product and protocol procedure-related AEs will be listed, and if the 
frequency of events allows, safety data will be summarized using descriptive methodology.
Adverse events will be classified by the most suitable term from the most current Medical 
Dictionary for Regulatory Activities (MedDRA) version.
The incidence of TEAEs will be presented by severity and by association with investigational 
product as perceived by the investigator.  AEs reported to occur prior to enrollment will be 
distinguished from those reported as new or increased in severity during the study.
All SAEs will be reported and classified by the most suitable term from the most current 
MedDRA version.
9.4.1.2.
Statistical Evaluation of Safety
Safety parameters for analysis will be:

AEs (including clinically significant ECGs)

clinical laboratory parameters

vital signs

C-SSRS assessments

Cogstate Pediatric Brief Battery parameters.
The parameters will be listed, and summarized using standard descriptive statistics.  Additional 
analysis will be performed if warranted upon review of the data.
Safety parameters may be summarized by region (Japanese vs. non-Japanese), if appropriate.
9.4.2. Pharmacokinetic Analyses
9.4.2.1.
Pharmacokinetic Parameter Estimation
Pharmacokinetic parameter estimates for lasmiditan will be calculated by standard 
noncompartmental methods of analysis from plasma lasmiditan concentrations, and listed and 
summarized using descriptive statistics.

H8H-MC-LAHX Clinical Pharmacology Protocol
Page 45
LY573144
The primary parameters for analysis will be Cmax, tmax, and AUC of lasmiditan.
Other noncompartmental parameters, such as half-life, apparent clearance, and apparent volume 
of distribution may be reported.
In addition to estimates of geometric means, the corresponding 95% CIs will also be determined.
Pharmacokinetic parameters may be summarized by region (Japanese vs. non-Japanese) if 
appropriate.
Additional analysis will be performed if warranted upon review of the data.
9.4.3. Data Review during the Study
Safety and PK data will be reviewed on an ongoing basis.  Doses may be adjusted when data are 
available from at least 3 patients with evaluable PK data in the primary cohort.  The purpose of 
the review is to assess safety/tolerability, evaluate PK data, and inform the dosing of subsequent 
patients.  The investigator and the Lilly sponsor team will make the determination regarding 
dosing, based on their review of the safety and PK data.  If lasmiditan plasma concentrations are 
unexpected relative to PK predictions, then the dose may be adjusted.  Additional reviews may 
be performed, as deemed appropriate.
9.5.
Interim Analyses
Because all patients in a cohort receive the same treatment, review of nonfinal data is not 
considered an interim analysis.  Therefore, there will be no interim analyses in this study.
9.6.
Data Monitoring Committee
An external data monitoring committee (DMC) will be used for this study. The DMC will 
review safety data on an ongoing basis concurrent with team and investigator reviews.

LY573144

answering any questions the patient or patient’s legal representative may have 
throughout the study and sharing in a timely manner any new information that may be 
relevant to the patient’s willingness to continue his or her participation in the study.

providing a copy of the ICF to the participant or the participant’s legal representative and 
retaining a copy on file.
A legal representative must give informed consent for a child to participate in this study.  In 
addition to informed consent given by the legal representative, the child may be required to give 
documented assent, if capable.
10.1.3. Data Protection

Participants will be assigned a unique identifier by the investigator. Any participant 
records or datasets that are transferred to the sponsor will contain the identifier only; 
participant names or any information that would make the participant identifiable will 
not be transferred.

The participant must be informed that his/her personal study-related data will be used 
by the sponsor in accordance with local data protection law. The level of disclosure 
must also be explained to the participant.

The participant must be informed that his/her medical records may be examined by 
Clinical Quality Assurance auditors or other authorized personnel appointed by the 
sponsor, appropriate IRB/IEC members, and inspectors from regulatory authorities.
10.1.4. Protocol Signatures
The sponsor’s responsible medical officer will approve the protocol, confirming that, to the best 
of his or her knowledge, the protocol accurately describes the planned design and conduct of the 
study.
After reading the protocol, each principal investigator will sign the protocol signature page and 
send a copy of the signed page to a Lilly representative.
10.1.5. Final Report Signature
The final report coordinating investigator or designee will sign the clinical study report for this 
study, indicating agreement that, to the best of his or her knowledge, the report accurately 
describes the conduct and results of the study.
If this investigator is unable to fulfill this function, another investigator will be chosen by Lilly to 
serve as the final report coordinating investigator.
The sponsor’s responsible medical officer and statistician will sign/approve the final clinical 
study report for this study, confirming that, to the best of his or her knowledge, the report 
accurately describes the conduct and results of the study.
10.1.6. Data Quality Assurance
To ensure accurate, complete, and reliable data, Lilly or its representatives will do the following:

H8H-MC-LAHX Clinical Pharmacology Protocol
Page 48
LY573144

provide instructional material to the study sites, as appropriate

provide sponsor start-up training to instruct the investigators and study 
coordinators.  This training will give instruction on the protocol, the completion 
of the CRFs, and study procedures.

make periodic visits to the study site

be available for consultation and stay in contact with the study site personnel by 
mail, telephone, or fax

review and verify data reported to detect potential errors.
In addition, Lilly or its representatives will periodically check a sample of the patient data 
recorded against source documents at the study site.  The study may be audited by Lilly or its 
representatives or regulatory agencies at any time.  Investigators will be given notice before an 
audit occurs.
The investigator will keep records of all original source data.  This might include laboratory 
tests, medical records, and clinical notes.  If requested, the investigator will provide the sponsor, 
applicable regulatory agencies, and applicable ERBs with direct access to the original source 
documents.
Data Capture System
The investigator is responsible for ensuring the accuracy, completeness, legibility, and timeliness 
of the data reported to the sponsor.
An electronic data capture (EDC) system will be used in this study for the collection of CRF 
data.  The investigator maintains a separate source for the data entered by the investigator or 
designee into the sponsor-provided EDC system.  The investigator is responsible for the 
identification of any data to be considered source and for the confirmation that data reported are 
accurate and complete by signing the CRF.
Additionally, electronic Clinical Outcome Assessment (eCOA) data, such as the cognition 
assessment, will be directly recorded by the patient into a computer.  The eCOA data will serve 
as the source documentation and the investigator does not maintain a separate, written, or 
electronic record of these data.
Data collected via the sponsor-provided data capture system(s) will be stored at third parties.  
The investigator will have continuous access to the data during the study and until 
decommissioning of the data capture system(s).  Prior to decommissioning, the investigator will 
receive an archival copy of pertinent data for retention.
Data managed by a central vendor, such as laboratory test data, will be stored electronically in 
the central vendor’s database system and reports will be provided to the investigator for review 
and retention.  Data will subsequently be transferred from the central vendor to the Lilly data 
warehouse.

H8H-MC-LAHX Clinical Pharmacology Protocol
Page 49
LY573144
Data from complaint forms submitted to Lilly will be encoded and stored in the global product 
complaint management system.
Data Protection
Data systems used for the study will have controls and requirements in accordance with local 
data protection law.
The purpose and use of patient personal information collected will be provided in a written 
document to the patient by the sponsor.
10.1.7. Study and Site Closure
10.1.7.1. Discontinuation of Study Sites
Study site participation may be discontinued if Lilly or its designee, the investigator, or the ERB 
of the study site judges it necessary for medical, safety, regulatory, or other reasons consistent 
with applicable laws, regulations, and GCP.
10.1.7.2. Discontinuation of the Study
The study will be discontinued if Lilly or its designee judges it necessary for medical, safety, 
regulatory, or other reasons consistent with applicable laws, regulations, and GCP.

Abbreviations and Definitions
Term
Definition
AE
adverse event:  Any untoward medical occurrence in a patient or clinical investigation 
patient administered a pharmaceutical product that does not necessarily have a causal 
relationship with this treatment.  An AE can therefore be any unfavorable and unintended 
sign (including an abnormal laboratory finding), symptom, or disease temporally associated 
with the use of a medicinal (investigational) product, whether or not related to the medicinal 
(investigational) product.
ALP
alkaline phosphatase
ALT
alanine aminotransferase
assent
Agreement from a child or other individual who is not legally capable of providing consent, 
but who can understand the circumstances and potential risks involved in participating in a 
study (required by some institutional review boards [IRBs]/ethical review boards [ERBs]).
AST
aspartate aminotransferase
AUC
area under the concentration-versus-time curve
CI
confidence interval
CIOMS
Council for International Organizations of Medical Sciences
Cmax
maximum observed drug concentration
complaint
A complaint is any written, electronic, or oral communication that alleges deficiencies 
related to the identity, quality, purity, durability, reliability, safety or effectiveness, or 
performance of a drug or drug delivery system.
compliance
Adherence to all the study-related requirements, good clinical practice (GCP) requirements, 
and the applicable regulatory requirements.
confirmation
A process used to confirm that laboratory test results meet the quality requirements defined 
by the laboratory generating the data and that Lilly is confident that results are accurate.  
Confirmation will either occur immediately after initial testing or will require that samples 
be held to be retested at some defined time point, depending on the steps required to obtain 
confirmed results.
CRF
case report form
CRP
Clinical Research Physician:  Individual responsible for the medical conduct of the study.  
Responsibilities of the CRP may be performed by a physician, clinical research scientist 
(CRS), global safety physician, or other medical officer.

Patients entered into a study are those who sign the informed consent form directly or 
through their legally acceptable representatives.
ERB

IEC
Independent Ethics Committee
informed consent
A process by which a patient voluntarily confirms his or her willingness to participate in a 
particular study, after having been informed of all aspects of the study that are relevant to 
the patient’s decision to participate.  Informed consent is documented by means of a 
written, signed, and dated informed consent form.
investigational 
product
A pharmaceutical form of an active ingredient or placebo being tested or used as a reference 
in a clinical study, including products already on the market when used or assembled 
(formulated or packaged) in a way different from the authorized form, or marketed products 
used for an unauthorized indication, or marketed products used to gain further information 
about the authorized form.
investigator
A person responsible for the conduct of the clinical study at a study site.  If a study is 
conducted by a team of individuals at a study site, the investigator is the responsible leader 
of the team and may be called the principal investigator.
IRB
institutional review board
Legal 
Representative
An individual or judicial or other body authorized under applicable law to consent, on 
behalf of a prospective patient, to the patient’s participation in the clinical study.
MedDRA
Medical Dictionary for Regulatory Activities
open label
A study in which there are no restrictions on knowledge of treatment allocation; therefore 
the investigator and the study participant are aware of the drug therapy received during the 
study.
