M18 in healthy elderly and young subjects following a 
single 200 mg oral dose of lasmiditan.

PK parameters:  Cmax, tmax, and AUC(0-∞)
Summary of Study Design:  
This is a single dose study to determine the PK of lasmiditan following a single 200 mg oral dose in healthy elderly 
and young subjects.  Two groups of subjects will be studied as follows:
Group 1 (healthy elderly subjects):  200 mg lasmiditan and matching placebo in a randomized double-blind 
cross-over design
Group 2 (healthy young subjects):  200 mg lasmiditan in an open label design
Subjects in Group 2 will be matched by race, sex, and body mass index (BMI) (±20%) to subjects in Group 1.  Both 
groups may be evaluated concurrently.  
Treatment Arms and Duration:  
Screening Period: 

H8H-MC-LAHA (a) Clinical Pharmacology Protocol
Page 8
LY573144
All subjects will participate in a screening visit up to 28 days prior to study drug dosing.  
Dosing Period:
Subjects in Group 1 will participate in 2 dosing periods. Subjects will be randomized to receive lasmiditan in one 
dosing period, and placebo in the other.  They will be admitted to the CRU the day prior to dosing (Day -1), and 
receive study drug on Day 1 for each dosing period. Subjects may be discharged from the CRU on Day 3 based on 
investigator discretion. There will be a washout period of 3 to 10 days between each dosing day. Subjects may stay 
as inpatient during the entire dosing period. 
Subjects in Group 2 will participate in 1 dosing period. They will be admitted to the CRU on Day -1 and receive 
study drug on Day 1. Subjects may be discharged from the CRU on Day 3 based on investigator discretion.
All subjects will be discharged from the study approximately 7 days post their final dose of lasmiditan.
Number of Subjects:
Up to 36 subjects may be enrolled to ensure 30 subjects (2 groups of 15) complete the study.  Group 1 will be 
subjects aged ≥65 years of age.  Attempts will be made to enroll at least 4 subjects who are ≥75 years of age. 
Group 2 will be subjects aged 18 to 45 years, inclusive.
Statistical Analysis:
Safety parameters that will be assessed include safety laboratory parameters, vital signs, and 12-lead 
electrocardiogram (ECG) parameters.  The parameters will be listed, and summarized using standard descriptive 
statistics, as appropriate.  
Pharmacokinetic parameter estimates for lasmiditan and its metabolites will be calculated by standard 
noncompartmental methods of analysis.  Pharmacokinetic parameter estimates will be evaluated to determine the 
impact of age on the PK of lasmiditan and its metabolites.  Log-transformed Cmax and AUC(0-∞) will be evaluated 
in a linear fixed-effects model with a fixed effect of age group.  The 90% confidence intervals (CIs) of the ratios of 
geometric means of the elderly group versus the young group will be presented.  
The tmax will be analyzed using a Wilcoxon signed rank test.  Estimates of the median difference based on the 
observed medians, 90% CIs and the p-value from the Wilcoxon test will be calculated.

3. Introduction
3.1.
Study Rationale
Lasmiditan is a small molecule 5-HT1F receptor agonist being developed for the acute treatment 
of migraine. Triptans, which are 5-HT1B/1D receptor agonists, are well established as an acute 
therapy for migraine, though they are not effective in all patients or attacks. Triptans were 
developed as cerebral vasoconstrictors, mediated via their affinity for 5-HT1B receptors located 
on vascular smooth muscle. Inherent in this mechanism of action is a liability for coronary 
vasoconstriction, and therefore, triptans are contraindicated in patients with cardiovascular 
disease. Unlike triptans, lasmiditan is a highly selective and potent agonist at the 5-HT1F 
receptor with >470-fold higher affinity for the 5-HT1F receptor than for 5-HT1B/1D receptors. 
Lasmiditan is under development as a neurally acting treatment for migraine without the 
vasoconstrictor liability of triptans. 
While the prevalence of migraine declines in population older than 50 years of age, between 5-
10% of population older than 65 still suffer from migraine (Victor et al. 2010).  Elderly patients 
are among those in the target population for lasmiditan.  
The present clinical study is being conducted to determine the PK of lasmiditan in elderly and 
young healthy subjects following a single oral administration of lasmiditan.
3.2.
Background
Two Phase 2 studies have been completed with lasmiditan in the acute treatment of migraine, 
using doses of up to 45 mg over 20 minutes of the intravenous (IV) formulation, and up to 
400 mg of the oral tablet formulation.  One Phase 3 randomized, double-blind, placebo 
controlled trial has been completed in the United States (COL MIG-301 [SAMURAI]), where 
1856 patients were randomized to 100 mg lasmiditan (630 subjects), 200 mg (609 subjects), or 
placebo (617 subjects), respectively. In the SAMURAI study, both 100 mg and 200 mg doses of 
orally administered lasmiditan achieved superior 2-hour pain free rate and the most relief of 
bothersome migraine symptoms (nausea, phonophobia, and photophobia) compared to placebo.
Five Phase 1 studies of lasmiditan have been completed and methods of administration included 
IV, oral, and sublingual. Single doses of lasmiditan were tolerated by healthy subjects when 
administered IV up to 180 mg over 60 minutes (H8H-MC-LAHA; 40 subjects), as solution 
formulations administered orally or sublingually up to doses of 400 and 32 mg, respectively 
(COL MIG-102; 60 subjects), as oral tablets or a solution formulation up to doses of 400 and 
200 mg, respectively (COL MIG-103; 44 subjects), and as oral tablets up to 200 mg (COL 
MIG-104; 30 subjects) and 400 mg (COL MIG-105; 55 subjects).
Across the completed Phase 1, 2, and 3 clinical studies, doses of 0.1 mg to 400 mg of lasmiditan 
were evaluated in healthy subjects or patients with migraine.  To date, lasmiditan has been 
administered to 213 healthy subjects, and to 1632 patients with migraine.  In the SAMURAI 
study, 1239 patients aged 18 to 79 years received at least 1 dose of lasmiditan. No PK data were 
obtained in this study, and by-age analyses of safety data have not been completed.  Compared 
with placebo, the most frequently reported lasmiditan treatment emergent adverse events 

H8H-MC-LAHA (a) Clinical Pharmacology Protocol

LY573144
(TEAEs) included somnolence, fatigue, dizziness, paresthesia, and hot flashes.  The majority of 
these TEAEs were mild or moderate in severity and none led to subject withdrawal.  One subject 
experienced an SAE of dizziness that was moderate in severity (lasmiditan 200 mg).
When administered intravenously at the highest dose of 180 mg (H8H-MC-LAHA), lasmiditan 
produced a statistically significant but small dose-related decrease in heart rate and increase in 
blood pressure, although the magnitude of these effects was considered unlikely to be of clinical 
significance.  Following oral administration at doses of up to 400 mg, heart rate again was 
slightly reduced, but there were no consistent effects on blood pressure.  The effects on vital 
signs were transient, not dose-related, and unlikely to be clinically significant given the intended 
intermittent use of lasmiditan.
Oral tablet doses of lasmiditan up to 400 mg (COL MIG-103) did not result in any clinically 
relevant changes in ECGs (including QT/QTc duration) following administration to healthy 
subjects.  In the thorough QT study (COL MIG-105) in healthy subjects, no clinically significant
changes in blood pressure, heart rate, or 12-lead ECG were observed at the 100 or 400 mg dose 
levels.  Lasmiditan caused no significant QT prolongation at either dose.
In healthy subjects, peak plasma concentrations of lasmiditan were observed approximately 1 to 
2.5 hours after a single oral dose, and the geometric mean terminal half-life was approximately 
4 to 6 hours. Lasmiditan exhibited dose-linear pharmacokinetics with low to moderate inter-
subject variability in exposure (AUC %CV ranged from 14 to 45%; COL MIG-102) after oral
dose administration.  Renal clearance of lasmiditan was low with approximately 2% of the dose 
recovered by 24 hours postdose.  Co-administration of lasmiditan with a high fat diet led to a 
delay in median tmax value by approximately 1 hour and a modest (~20%) increase in lasmiditan 
Cmax and AUC values, relative to that under fasted conditions. Based on the short terminal 
half-life observed following a single oral dose, accumulation of lasmiditan is not expected.  
There are currently no PK data from elderly subjects available from the completed or ongoing 
trials.
Human metabolism has been investigated using LC-MS/MS following oral dosing with 
lasmiditan, where up to 11 metabolites were detected in plasma and urine, including 3 major 
metabolites (M7, M8, and M18).  These metabolites lacked significant pharmacological activity 
at the 5-HT1F receptor and were generally considered to be pharmacologically inactive.  The 
relative proportions of metabolites to intact lasmiditan remained reasonably constant throughout 
the oral dose range studied and their PK were approximately linear.  The half-life of the 
metabolites ranged from ~4.5 hours to >12 hours.
3.3.
Benefit/Risk Assessment
The primary objective for this study is to evaluate the PK profile of lasmiditan after a single oral 
dose in healthy elderly and young subjects. There is no anticipated therapeutic benefit for the 
subjects.
Lasmiditan has been well tolerated by healthy subjects as single oral doses up to 400 mg.  
Elderly patients were enrolled in the completed Phase 3 program (SAMURAI) for acute 

H8H-MC-LAHA (a) Clinical Pharmacology Protocol
Page 15
LY573144
migraine treatment that tested single doses up to 200 mg, where a second dose was permitted 
within the same day if migraine relief had not been achieved.. No clinically significant safety or 
tolerability concerns have been identified in subjects to date for lasmiditan up to the highest 
single oral dose given (400 mg). Dosing of lasmiditan in this study will be conducted in an 
inpatient setting, and subjects will be monitored in house for at least 48 hours after dosing.
More information about the known and expected benefits, risks, SAEs and reasonably 
anticipated AEs of lasmiditan are to be found in the IB.

5. Study Design
5.1.
Overall Design
This is a single dose study to determine the PK of lasmiditan following a single 200 mg oral dose
in healthy elderly and young subjects.  Two groups of subjects will be evaluated as follows:

Group 1 (healthy elderly subjects; ≥65 years):  200 mg lasmiditan and placebo in a 
randomized, double-blind, 2-period crossover design

Group 2 (healthy young subjects; 18 to 45 years, inclusive):  200 mg lasmiditan in an 
open label design
Subjects in Group 2 will be matched by primary race, sex, and BMI (±20%) to subjects in 
Group 1 where feasible.  Both groups may be studied concurrently.  
Screening Period:
All subjects will participate in a screening visit up to 28 days prior to study drug dosing.
Dosing Period:
Subjects in Group 1 will participate in 2 dosing periods.  They will be admitted to the CRU on 
the day prior to dosing (Day -1), and receive study drug on Day 1 for each dosing period.  
Subjects may be discharged from the CRU on Day 3 based on investigator discretion.  There will 
be a washout period of 3 to 10 days between each dose.  Subjects may stay in the CRU as 
inpatient during the entire dosing period.
Subjects in Group 2 will participate in 1 dosing period.  They will be admitted to the CRU on 
Day -1 and receive study drug on Day 1.  Subjects may be discharged from the CRU on Day 3 
based on investigator discretion.
All subjects will be discharged from the study approximately 7 days post their final dose of 
lasmiditan.
5.2.
Number of Participants
Up to 36 subjects may be enrolled to ensure 30 subjects (2 groups of 15) complete the study.  
Group 1 will be subjects aged ≥65 years of age.  Attempts will be made to enroll at least 
4 subjects who are ≥75 years of age. Group 2 will be young subjects aged 18 to 45 years, 
inclusive. Subjects who discontinue from the study prior to completion may be replaced. 
5.3.
End of Study Definition
End of the study is the date of the last visit or last scheduled procedure shown in the Schedule of 
Activities (Section 2) for the last subject.
5.4.
Scientific Rationale for Study Design
A subject- and investigator-blinded, randomized and placebo controlled design is being used for 
Group 1, to minimize bias on the safety and tolerability objective for this group. A crossover 

H8H-MC-LAHA (a) Clinical Pharmacology Protocol
Page 18
LY573144
design improves the sensitivity for detecting any safety / tolerability signals in the elderly 
subjects, particularly in relation to vital signs (as described in Section 3.2). Lasmiditan 
administered by IV infusion has been generally well tolerated by healthy subjects, with most 
AEs being mild in intensity at all dose levels, but there was a dose-related increase in the number 
of moderate AEs.  The most frequently reported AEs following IV administration in healthy 
subjects were nervous system related (tiredness, drowsiness, dizziness, somnolence, fatigue, and 
paresthesia).  The AE profile of orally administered lasmiditan in healthy subjects was 
qualitatively similar to that observed in the IV study.  At the highest dose of 400 mg, most AEs 
were mild in severity and none were severe.
A minimal duration for the washout period is 3 days, which is adequate based on the half-life of 
lasmiditan.
An open label design is being used for Group 2, as the key objective for this group is based on 
PK, which is not subject to bias.  
Conducting the study in healthy subjects mitigates the potential confounding effects of the 
disease state and concomitant medications.
The nonclinical and clinical data enable conducting clinical pharmacology studies in young and 
elderly healthy subjects.  The single dose design of this study limits exposure of subjects to 
lasmiditan and is appropriate to address the study objectives.
5.5.
Justification for Dose
The dose level of 200 mg lasmiditan has been well tolerated in previous studies of healthy 
subjects and in elderly patients enrolled in the SAMURAI study. This dose level is in the 
therapeutic dose range and is expected to be the highest potential recommended single dose for 
lasmiditan.

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 electrocardiogram (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 Day 1.  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.

screening or Day -1 upon repeat testing, or a history of it.
6.2.1. Rationale for Exclusion of Certain Study Candidates
The use of lasmiditan in elderly patients is anticipated, thus this study will specifically examine 
the PK, safety, and tolerability in an elderly population (Group 1).  Criteria 2 and 17 define the 
elderly population for the purposes of this study.  Therefore, subjects meeting the elderly criteria 
are excluded from Group 2. 
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
Lasmiditan or placebo will be administered after an overnight fast of at least 8 hours.  Subjects 
will be given a snack prior to bedtime.  Subjects will abstain from water 1 hour before and after 
dosing (except for water given with the dose).  Subjects may be permitted to consume a light 
breakfast (e.g. cereal, toast) at 1 hour postdose at the discretion of the investigator; with the 
exception of this light breakfast, subjects will remain fasting for 3 hours postdose at which time a 
meal will be served.
6.3.2. Caffeine, Alcohol, and Tobacco
Caffeine – Subjects will refrain from consuming xanthine- or caffeine-containing food and 
drinks from 48 hours prior to admission, and while resident at the CRU.

H8H-MC-LAHA (a) Clinical Pharmacology Protocol
Page 23
LY573144
Alcohol – Subjects will not consume alcohol for 48 hours prior to admission, and while resident 
at the CRU.
Tobacco – Subjects will refrain from smoking while resident at the CRU.  
6.3.3. Activity
No strenuous exercise will be allowed for 48 hours prior to admission until after discharge from 
the study.
6.4.
Screen Failures
Individuals being recruited into Group 1 may be re-screened once.  The interval between 
re-screenings should be at least 1 week.  When re-screening is performed, the individual must 
sign a new informed consent form (ICF) and will be assigned a new identification number.
Individuals being recruited into Group 2 who do not meet the criteria for participation in this 
study (screen failure) may not be re-screened.

tablets or 1 or 2 matching placebos.  Whether subjects will receive 1 OR 2 tablets will be determined prior to study 
start.
The investigator or designee is responsible for:

explaining the correct use of the investigational product to the site personnel 

verifying that instructions are followed properly

maintaining accurate records of investigational product dispensing and collection

and 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
Each tablet of lasmiditan contains 100 or 200 mg of active ingredient and is provided as bulk 
supply in bottles.  Placebo tablets look identical but contain no active ingredient and will be 
provided in similar bulk bottles.
The investigational product will be labeled according to the country’s regulatory requirements.

H8H-MC-LAHA (a) Clinical Pharmacology Protocol

LY573144
7.2.
Method of Treatment Assignment
Subjects in Group 1 will be randomized to 1 of 2 treatment sequences (lasmiditan in Period 1 and 
placebo in Period 2; or placebo in Period 1 and lasmiditan in Period 2) using a 
computer-generated allocation schedule.
All subjects in Group 2 will receive the same treatment and will not be subject to randomization.
7.2.1. Selection and Timing of Doses
On Day 1, subjects will receive a single oral dose of 200 mg lasmiditan (Group 1 and 2) or 
placebo (Group 1 only).
The actual time of all dose administrations will be recorded in the subject’s case report form 
(CRF).
7.3.
Blinding
Group 1 will be subject- and investigator-blind.  For this group, the investigator, site staff (except 
unblinded pharmacy staff), and subjects will be blinded to study treatment.
Group 2 will be open-label.
Emergency codes for Group 1 will be available to the investigator.  A code, which reveals the 
treatment for a specific study subject, may be opened during the study only if the subject’s 
well-being requires knowledge of the subject’s treatment assignment.
If a subject’s study treatment assignment is unblinded, the subject must be discontinued from the 
study, unless the investigator obtains specific approval from a Lilly clinical pharmacologist or 
clinical research physician for the study participant to continue in the study.  During the study, 
emergency unblinding should occur only by accessing the study subject’s emergency code.
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.
7.4.
Dose Modification
Dose modification will not be allowed during the study.
7.5.
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 treatment.
Only participants 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 an environmentally controlled and monitored (manual 

H8H-MC-LAHA (a) Clinical Pharmacology Protocol
Page 26
LY573144
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 investigational product will be administered at the clinical site, and documentation of 
treatment administration will occur at the site.
7.7.
Concomitant Therapy
Concomitant medications are to be avoided during the study unless required to treat an AE or for 
the treatment of an ongoing medical problem.
Contraceptive medication is permitted as outlined in Inclusion Criterion 1b.  For subjects in 
group 1 (elderly), hormone replacement therapy, thyroid replacement therapy, prophylactic 
anti-platelet drugs, angiotensin-converting enzyme (ACE) inhibitors, angiotensin receptor 
blockers (ARBs), thiazides, statins, and proton pump inhibitors (PPIs) may be permitted 
following discussion with the Lilly CRP/CP, or designee.
Acetaminophen may be allowed at the investigator’s discretion, up to 2 grams in a 24-hour
period, without prior consultation.
If the need for concomitant medication (other than acetaminophen) arises, inclusion or 
continuation of the subject may be at the discretion of the investigator after consultation with a 
Lilly clinical pharmacologist, CRP, or designee.  Any medication used during the course of the 
study must be documented.
7.8.

8. Discontinuation Criteria
8.1.
Discontinuation from Study Treatment
Subjects discontinuing from the investigational product prematurely for any reason must 
complete adverse event and discharge 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/CRP or 
designee 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 
the Lilly clinical pharmacologist/CRP or designee to allow the inadvertently enrolled patient 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

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

Subject Decision
o
the subject, or legal representative, requests to be withdrawn from the study.
8.3.
Subjects Lost to Follow-up
A subject will be considered lost to follow-up if he or she fails to return for a scheduled visit 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).
Appendix 2 lists the laboratory tests that will be performed for this study.
Appendix 4 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.
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.
After the informed consent form (ICF) 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 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.

H8H-MC-LAHA (a) Clinical Pharmacology Protocol
Page 29
LY573144
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 CRP/CP, or its designee, of any SAE as soon as 
practically possible.
All AEs occurring after signing the ICF are recorded in the case report forms and assessed for 
serious criteria.  The SAE reporting to the sponsor begins after the subject has signed the ICF 
and has received investigational product.  However, if an SAE occurs after signing the ICF, but 
prior to receiving investigational product, the SAE should be reported to the sponsor as per SAE 
reporting requirements and timelines (see Section 9.2) if it is considered reasonably possibly 
related to study procedure.
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. 
Pregnancy (maternal or paternal exposure to Investigational product [IP]) does not meet the 
definition of an adverse event.  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 IP 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.

H8H-MC-LAHA (a) Clinical Pharmacology Protocol
Page 30
LY573144
9.2.2. Complaint Handling
Lilly collects product complaints on IPs 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 he or she has a 
complaint or problem with the IP so that the situation can be assessed.
9.3.
Treatment of Overdose
For the purposes of this study, an overdose of lasmiditan is considered any dose higher than the 
planned study dose.  There is no specific antidote for lasmiditan.  In the event of overdose, the 
subject should receive appropriate supportive care and AEs should be documented.
No drug interaction studies in humans have yet been performed with lasmiditan.
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).
Any clinically significant findings from laboratory tests that result in a diagnosis and that occur 
after the subject receives the first dose of IP should be reported to Lilly or its designee as an AE
via eCRF.
9.4.2. Vital Signs
For each subject, vital signs measurements should be conducted according to the Schedule of 
Activities (Section 2).
Blood pressure and pulse rate should be measured after at least 5 minutes supine.  Elderly 
subjects may be permitted to lie in a semi-recumbent position, if required.  All 
supine/semi-recumbent blood pressure and pulse rate except for screening will be done in 
triplicates at approximately 1-minute intervals.  Where applicable, the last triplicate vital sign 
can be used as the supine/semi-recumbent vital sign for the calculation of orthostatic changes.
Where orthostatic measurements are required, subjects should be supine/semi-recumbent for at 
least 5 minutes and stand for at least 2 minutes.
If the subject feels unable to stand, supine/semi-recumbent 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.
9.4.3. Electrocardiograms
For each subject, ECGs should be collected according to the Schedule of Activities (Section 2).  

H8H-MC-LAHA (a) Clinical Pharmacology Protocol
Page 31
LY573144
Any clinically significant findings from ECGs that result in a diagnosis and that occur after the 
subject receives the first dose of the IP, should be reported to Lilly, or its designee, as an AE via 
eCRF. 
For each subject, a single 12-lead digital electrocardiogram (ECG) will be collected according to 
the Schedule of Activities (Section 2).  Electrocardiograms must be recorded before collecting 
any blood samples.  Subjects must be supine for at least 5 minutes before ECG collection and 
remain supine but awake during ECG collection.  Electrocardiograms may be obtained at 
additional times, when deemed clinically necessary.  All ECGs recorded should be stored at the 
investigational site.
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 
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 finding is identified (including, but not limited to, changes in QT/QTc 
interval from baseline) after enrollment, the investigator will determine if 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 collection.  Any new clinically relevant finding should be reported as an 
adverse event.
9.4.4. Safety Monitoring
The Lilly clinical pharmacologist or CRP/scientist will monitor safety data throughout the course 
of the study.
Lilly will review SAEs within time frames mandated by company procedures.  The Lilly clinical 
pharmacologist or CRP will periodically review the following data:

trends in safety data

laboratory analytes 

AEs
9.4.4.1.
Hepatic Safety
If a study subject experiences elevated ALT ≥3X ULN, ALP ≥2X ULN, or elevated total 
bilirubin ≥2X ULN, liver tests (Appendix 4) should be repeated within 3 to 5 days including 
ALT, AST, ALP, TBL, direct bilirubin, gamma-glutamyl transferase (GGT), and creatinine 
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 Lilly clinical pharmacologist or CRP.  Monitoring 
should continue until levels normalize and/or are returning to approximate baseline levels. 

H8H-MC-LAHA (a) Clinical Pharmacology Protocol
Page 32
LY573144
Additional safety data should be collected if 1 or more of the following conditions occur: 

elevation of serum ALT to ≥ 5 × ULN on two 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 a SAE.
9.5.
Pharmacokinetics
At the visits and times specified in the Schedule of Activities, venous blood samples of 
approximately 2 mL each will be collected to determine the plasma concentrations of lasmiditan
and metabolites.
A maximum of 3 samples 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.
9.5.1. Bioanalysis
Samples will be analyzed at a laboratory approved by the sponsor and stored at a facility 
designated by the sponsor.
Plasma concentrations of lasmiditan and three major metabolites will be assayed using a 
validated LC/MS/MS method.  
Plasma remaining after the analyses may be used for exploratory work to further understand the 
disposition and metabolism of lasmiditan.
Bioanalytical samples collected to measure lasmiditan and metabolite concentrations will be 
retained for a maximum of 1 year following last subject visit for the study.  
9.6.
Pharmacodynamics
This section is not applicable for this study.
9.7.
Genetics
A mandatory blood sample will be collected for pharmacogenetic analysis as specified in the 
Schedule of Activities, 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 response to lasmiditan and to 
investigate genetic variants thought to play a role in migraine.  Assessment of variable response 
may include evaluation of AEs or differences in efficacy.  

H8H-MC-LAHA (a) Clinical Pharmacology Protocol
Page 33
LY573144
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 impose shorter time limits, for the study at a facility 
selected by Lilly or its designee.  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 lasmiditan or after lasmiditan is commercially available.  
Molecular technologies are expected to improve during the 15-year storage period and therefore 
cannot be specifically named.  However, existing approaches include whole genome or exome 
sequencing, genome wide association studies, multiplex assays, and candidate gene studies.  
Regardless of technology utilized, data generated will be used only for the specific research 
scope described in this section.

Statistical Considerations and Data Analysis
10.1. Sample Size Determination
Up to 36 subjects may be enrolled in order that 30 subjects (2 groups of 15) complete the study.
For AUC or Cmax, assuming inter-subject CV of 40% and a sample size of 15 per group, the 
90% confidence interval around the ratio of the geometric means (elderly group : non-elderly 
group) will have half-width of 24.3% on the log scale with 90% coverage probability.
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 subjects’ age, sex, weight, height, BMI, race, and other demographic characteristics will be 
recorded and summarized using descriptive statistics.
10.3. Statistical Analyses
Statistical analysis of this study will be the responsibility of Eli Lilly and Company or its 
designee.
Pharmacokinetic analyses will be conducted on data from all subjects who receive one dose of 
the IP and have evaluable PK.  
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.  
10.3.1. Safety Analyses
10.3.1.1. Clinical Evaluation of Safety
All IP 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 IP as perceived by the investigator.  Symptoms reported to occur prior to 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.
The number of IP-related SAEs will be reported.
10.3.1.2. Statistical Evaluation of Safety
Safety parameters that will be assessed include safety laboratory parameters, vital signs, and 
ECG parameters.  The parameters will be listed and summarized using standard descriptive 

H8H-MC-LAHA (a) Clinical Pharmacology Protocol
Page 35
LY573144
statistics, as appropriate.  Additional analysis will be performed if warranted upon review of the 
data.
10.3.2. Pharmacokinetic Analyses
10.3.2.1. Pharmacokinetic Parameter Estimation
Pharmacokinetic parameter estimates for lasmiditan and its metabolites will be calculated by 
standard noncompartmental methods of analysis and will be listed and summarized for each 
group of subjects using descriptive statistics.  
The primary parameters for analysis will be maximum drug concentration (Cmax) and area under 
the concentration versus time curve (AUC) from zero to infinity (AUC[0-∞]), and the time of 
maximum drug concentration (tmax) of lasmiditan and its metabolites.  Other noncompartmental 
parameters, such as half-life, apparent clearance, and apparent volume of distribution may be 
reported.
10.3.2.2. Pharmacokinetic Statistical Inference
Pharmacokinetic parameter estimates will be evaluated to determine the impact of age on the PK
of lasmiditan and its metabolites. Log-transformed Cmax and AUC(0-∞) will be evaluated in a 
linear fixed-effects model with a fixed effect of age group.  The 90% CIs of the ratios of 
geometric means of the elderly group versus the young group will be presented.  
The tmax will be analyzed using a Wilcoxon signed rank test.  Estimates of the median difference 
based on the observed medians, 90% CIs and the p-value from the Wilcoxon test will be 
calculated.
Additional analysis will be performed if warranted upon review of the data.
10.3.3. Interim Analyses
No interim analyses are planned for this study.  If an unplanned interim analysis is deemed 
necessary, the Lilly clinical pharmacologist, CRP/investigator, or designee will consult with the 
appropriate medical director or designee to determine if it is necessary to amend the protocol.
