1. Protocol Synopsis
Title of Study:
A Randomized, Double-Blind, Four-Period, Crossover Study to Evaluate the Cardiovascular Effect of Single Oral 
Doses of Lasmiditan when Coadministered with Single Oral Doses of Sumatriptan in Healthy Subjects
Rationale: 
The study will assess the cardiovascular effects of coadministration of single doses of sumatriptan 100 mg and 
single doses of lasmiditan 200 mg as measured by vital signs using 24-hour ambulatory blood pressure (ABP) 
monitoring (ABPM).  Pharmacokinetics (PK), safety, and tolerability will also be reported.  Sumatriptan is known to 
cause a transient increase in blood pressure (BP) and is contraindicated in patients with moderate and severe 
hypertension and mild uncontrolled hypertension.  Initial studies with lasmiditan have identified mild effects on 
cardiovascular parameters (pulse rate [PR] and BP). In clinical practice, lasmiditan may be coadministered with 
sumatriptan.  Therefore, Study H8H-MC-LAHU is being conducted to evaluate the cardiovascular effects and PK 
impact of coadministration of lasmiditan with sumatriptan in healthy subjects.
Objectives/Endpoints:
Objectives
Endpoints
Primary
To compare and contrast the cardiovascular effects of 
lasmiditan 200 mg and sumatriptan 100 mg administered 
together to the cardiovascular effects of single doses of 
either drug administered alone.
Systolic BP (SBP), diastolic BP (DBP), mean arterial 
pressure (MAP), and PR per 24-hour ABPM.
Secondary

To evaluate PK of lasmiditan 200 mg and 
sumatriptan 100 mg administered either alone 
or together.

To evaluate the safety and tolerability of 
lasmiditan 200 mg and sumatriptan 100 mg.

Maximum observed drug concentration (Cmax), 
time of maximum observed drug concentration 
(tmax), area under the concentration versus time 
curve (AUC) from time 0 extrapolated to 
infinity (AUC)[0-∞]), and AUC from time 0 to 
time t, where t is the last time point with a 
measurable concentration (AUC[0-tlast]).

A summary of the number of 
treatment-emergent adverse events (TEAEs) 
and serious adverse events (SAEs).
Summary of Study Design:
Study H8H-MC-LAHU is a randomized, double-blind (subject- and investigator-blinded), crossover study with 
4 study periods in healthy subjects to investigate the cardiovascular effects, PK, and safety and tolerability of oral 

H8H-MC-LAHU(c) Clinical Pharmacology Protocol

doses of lasmiditan alone, sumatriptan alone, and sumatriptan in combination with lasmiditan.  All subjects will 
participate in 4 treatment periods.  The treatments are as follows:

Treatment A:  lasmiditan 200 mg + sumatriptan 100 mg

Treatment B:  lasmiditan 200 mg + placebo

Treatment C:  sumatriptan 100 mg + placebo

Treatment D:  placebo + placebo
Each subject will be randomized to one of 4 treatment sequences in a William’s square design (i.e. ABCD, BCDA, 
CDAB, and DABC).
Treatment Arms and Planned Duration for Individual Subjects:  
Screening Period:
All subjects will participate in a screening visit up to 28 days prior to Period 1 study drug dosing.
Treatment Periods:
All subjects will participate in 4 treatment periods.  Subjects will be randomized to 1 of 4 treatment sequences.  
They will be admitted to the clinical research unit (CRU) the day prior to dosing (Day -1) in Period 1, and will be 
dosed on Day 1 of each treatment period according to their assigned treatment sequence. Subjects will be 
discharged from the CRU on Day 3 of Period 4, following the collection of all ABP measurements and 
pharmacokinetic (PK) blood samples.  There will be a washout of at least 4 days between each dosing day.
All subjects will be discharged from the study at least 5 days after discharge from Period 4.
Number of Subjects:
Up to 40 subjects may be enrolled to ensure 30 subjects complete the study.
Statistical Analysis:
Cardiovascular parameters that will be assessed by ABPM include peak hourly mean values of SBP, DBP, and 
MAP, and nadir hourly mean value of PR.  The parameters will be listed, and summarized using descriptive 
statistics, as appropriate. Changes from baseline in cardiovascular parameters SBP, DBP, MAP, and PR will be 
analyzed to determine the impact of a single dose of sumatriptan 100 mg on the cardiovascular parameters of 
lasmiditan. A repeated measures linear mixed-effects model with baseline as a covariate, fixed effects for time 
point, treatment, period (1, 2, 3, or 4), treatment sequence and the treatment by time point interaction, and a random 
effect for subject will be used. Least squares (LS) means and treatment differences ([lasmiditan + sumatriptan] -
[lasmiditan + placebo]) will be calculated and presented with the corresponding confidence intervals (CIs). The 
same model will be used to assess the impact of a single dose of lasmiditan 200 mg on the cardiovascular parameters
of sumatriptan.
Pharmacokinetic parameter estimates for lasmiditan, its metabolites, and sumatriptan will be calculated by standard 
noncompartmental methods of analysis.  Pharmacokinetic parameter estimates will be evaluated to determine the 
impact of a single dose of sumatriptan 100 mg on the PK of lasmiditan and its metabolites.  Log-transformed Cmax
and AUC parameters will be evaluated using a linear effects model with fixed effects for treatment, period (1, 2, 3, 

H8H-MC-LAHU(c) Clinical Pharmacology Protocol

LY573144
or 4), and treatment sequence, and a random effect for subject.  From this model, the 90% CIs of the ratios of 
geometric means from Treatment A (lasmiditan + sumatriptan) will be determined and presented versus those of 
Treatment B (lasmiditan + placebo).  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.  The same model will be independently used to assess the impact of a single dose of lasmiditan 200 mg 
on the PK of sumatriptan.
Safety parameters that will be assessed include clinical laboratory parameters, vital signs, and 12-lead 
electrocardiogram (ECG) parameters.  The parameters will be listed, and summarized using descriptive statistics, as 
appropriate.

3. Introduction
3.1.
Study Rationale
Lasmiditan is a small molecule serotonin (5-hydroxytryptamine; 5-HT)1F receptor agonist being 
developed for the acute treatment of migraine.  Triptans, which are 5-HT1B and 5-HT1D 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 >450-fold higher affinity for the 5-HT1F receptor than for 
5-HT1B and 5-HT1D receptors (Capi et al. 2017).  Lasmiditan is under development as a neurally 
acting treatment for migraine without the vasoconstrictor liability of triptans.
Sumatriptan is a synthetic triptan used for the treatment of migraine and cluster headaches, 
known to cause a transient increase in blood pressure (BP), and is contraindicated in patients 
with moderate and severe hypertension, and mild uncontrolled hypertension.
Sumatriptan has an oral bioavailability of approximately 15%, partially attributable to the 
presystemic metabolism of sumatriptan via monoamine oxidase (MAO).  Due to the 
predominance of this metabolism pathway, the potential for MAO inhibitors to cause clinically 
significant drug-drug interactions is high.  In vitro studies suggest that lasmiditan is not a 
monoamine oxidase inhibitor, and it is expected that the likelihood of lasmiditan affecting 
sumatriptan pharmacokinetics (PK) is low.  In clinical practice, lasmiditan may be 
coadministered with sumatriptan; it is therefore pertinent to determine the potential for 
pharmacodynamic (PD) or PK drug interactions. This study will assess the effect of single doses 
of sumatriptan 100 mg on the cardiovascular effects of single doses of lasmiditan 200 mg; the 
effect of single doses of lasmiditan 200 mg on the cardiovascular parameters of sumatriptan, and 
the cardiovascular effects of either drug alone, as measured by vital signs using 24-hour 
ambulatory blood pressure (ABP) monitoring (ABPM).  Pharmacokinetics, safety and 
tolerability will also be reported.
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 (Study COL 
MIG-201), and up to 400 mg of the oral tablet formulation (COL MIG-202).  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 and 200 mg doses of orally administered lasmiditan achieved superior 2-hour 
pain free rate and the relief of most bothersome migraine symptoms (nausea, phonophobia, and 
photophobia) compared to placebo.

H8H-MC-LAHU(c) Clinical Pharmacology Protocol
Page 16
LY573144
Five Phase 1 studies of lasmiditan have been completed and methods of administration included 
IV, oral, and sublingual.  Lasmiditan was tolerated by healthy subjects when administered IV up 
to 180 mg over 20 or 60 minutes (H8H-BD-LACA; 40 subjects), as a solution formulation 
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 of 200 mg (COL MIG-104; 30 subjects) and up 
to 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; methods of administration included 
IV, oral, and sublingual.  Compared with placebo, the most frequently reported lasmiditan 
treatment-emergent adverse events (TEAEs) across all studies 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 patient in the Phase 2 dose-ranging study in 
migraineurs experienced a serious adverse event (SAE) of dizziness that was moderate in 
severity, occurred approximately 30 minutes after dosing, and was considered related to 
lasmiditan.  The subject was admitted to hospital for overnight observation following review by 
the hospital emergency room physician.
When administered IV at the highest dose of 180 mg (H8H-MC-LACA), lasmiditan produced a 
statistically significant but small dose-related decrease in pulse rate (PR) and increase in BP, 
although the magnitude of these effects was considered unlikely to be of clinical significance in 
this group of healthy subjects.  Following oral administration at doses of up to 400 mg
(COL MIG-102), PR again was slightly reduced, but there were no consistent effects on BP.  The 
effects on vital signs were transient, not dose-related, and unlikely to be clinically significant 
given the intended intermitten7t use of lasmiditan.
Oral tablet doses of lasmiditan up to 400 mg (COL MIG-103) did not result in any clinically 
relevant changes in electrocardiograms (ECGs) (including QT interval/corrected QT interval 
[QTc]) following administration to healthy subjects.  In the thorough QT study (COL MIG-105) 
in healthy subjects, no clinically significant changes in BP, PR, 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 ranging from 25 to 400 mg, and the geometric mean terminal 
half-life was approximately 4 to 6 hours.  Lasmiditan exhibited dose-linear PK; low to moderate 
inter-subject variability in exposure was observed across doses (coefficient of variation [%CV]
up to 61% and 45% for maximum observed drug concentration [Cmax] and area under the curve 
[AUC], respectively; COL MIG-102).  Co-administration of lasmiditan with a high fat diet 
(COL MIG-104) led to a delay in median time of maximum observed drug concentration (tmax) 
value by approximately 1 hour and a modest (~20%) increase in lasmiditan Cmax and AUC 
values, relative to that under fasted conditions.    
Following exploratory analysis of human plasma samples from adult subjects receiving oral 
lasmiditan, 3 major human metabolites (M7, M8, and [S,R]-M18) were observed.  Ketoreduction 

H8H-MC-LAHU(c) Clinical Pharmacology Protocol

LY573144
of lasmiditan to M8 (alcohol) appears to be the major metabolic pathway, presumably via non-
CYP enzymes.  In human liver microsomes, CYP1A2 and CYP3A4 appear to be involved to a 
minor extent in lasmiditan metabolism.  Unchanged lasmiditan comprises approximately 2% of 
the dose excreted in urine.  Lasmiditan is a very weak inhibitor of CYP3A4, CYP2D6, and 
P-glycoprotein.
3.3.
Benefit/Risk Assessment
The primary objective for this study is to compare and contrast the cardiovascular effects of 
lasmiditan and sumatriptan, in relation to vital signs following a single oral dose alone or when 
coadministered in healthy 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.  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).  
Sumatriptan is a marketed drug and will be administered within the recommended dose regimen 
for clinical use (100 mg).  Sumatriptan is known to cause transient increases in blood pressure at 
this dose.  This dose regimen has been tolerated in previous PK/PD studies in healthy subjects 
(for example Nappi et al. 1994). Similar to the adverse events (AEs) observed following dosing 
with lasmiditan, AEs observed following dosing with sumatriptan include, but are not limited to, 
fatigue, dizziness, paresthesia, and hot flashes.
Dosing of lasmiditan and sumatriptan in this study will be conducted in an inpatient setting and 
subjects will be monitored in-house for at least 24 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 investigator's brochure (IB).
More detailed information about the known and expected benefits and risks of sumatriptan may

Screening Period:
All subjects will participate in a screening visit up to 28 days prior to Period 1 study drug dosing.
Treatment Periods:
All subjects will participate in 4 treatment periods.  Subjects will be randomized to one of 
4 treatment sequences.  They will be admitted to the clinical research unit (CRU) the day prior to 
dosing (Day -1) in Period 1, and will be dosed on Day 1 of each treatment period according to 
their assigned treatment sequence (Table LAHU.2).  Subjects will be discharged from the CRU 
on Day 3 of Period 4 following the collection of all ABP measurements and PK blood samples.  
There will be a washout of at least 4 days between each dosing day.
All subjects will be discharged from the study at least 5 days after discharge from Period 4.

5.2.
Number of Participants
Up to 40 subjects may be enrolled to ensure 30 subjects complete the study.
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 double-blind (subject- and investigator-blinded), randomized, and placebo-controlled design is 
being used to minimize bias on the primary objective of this study.  
The study blind will be maintained by either use of a blindfold, or placement of the tablets in an 
amber vial to disguise their appearance; the sumatriptan tablets to be used in this study will be 
similar in shape and size to both lasmiditan and lasmiditan placebo (round and approximately 
10 mm in diameter), therefore lasmiditan placebo will also be used as the placebo for 
sumatriptan.
A crossover design improves the sensitivity for detecting any cardiovascular signals by means of
vital signs (as are described in Section 3.2).  Conducting the study in healthy subjects mitigates 
the potential confounding effects of the disease state and concomitant medications.
The washout period is at least 4 days, which is adequate based on the half-life of lasmiditan.
The nonclinical and clinical data enable conducting clinical pharmacology studies in healthy 
subjects.  The single dose design of this study limits exposure of subjects to lasmiditan and is 
appropriate to address the study objectives.
Preliminary data suggest that lasmiditan may inhibit renal transporters involved in the active 
secretion of creatinine into the urine, which can lead to a decrease in the renal clearance of 
creatinine in vivo and subsequent increase in serum creatinine.  The change in creatinine renal 
clearance is often delayed and transient.  Hence, frequent sampling with urine collection is
necessary for capturing temporal changes in creatinine disposition. The inclusion of serum 
cystatin C, which provides a more precise measure of glomerular filtration rate (GFR), enables 
differentiation between changes in creatinine transport versus change in renal function.
5.5.
Justification for Dose
The dose level of 200 mg lasmiditan has been well tolerated in previous studies of healthy 
subjects.  This dose level is expected to be the highest recommended single dose for lasmiditan.
The dose of sumatriptan (100 mg) is within the range used in clinical practice.  More detailed 
information can be found in the Sumatriptan Package Insert.

6. Study Population
Eligibility of subjects for the study will be based on the results of screening medical history, 
physical examination, vital signs, clinical laboratory tests and ECG. 
The nature of any conditions present at the time of the physical examination and any preexisting 
conditions will be documented.
Screening may occur up to 28 days prior to enrollment (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.

6.2.1. Rationale for Exclusion of Certain Study Candidates
Criteria [1] through [7] define a healthy population suitable for evaluation in a Phase 1 study.  
Criteria [8] and [9] prevent conflict of interest in study participants.  Criteria [10] through [38] 
predominantly exclude medical conditions, medication intolerance, and concomitant medication 
use that may confound the assessment of study endpoints.
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 and sumatriptan will be administered after an overnight fast of at least 8 hours.  On 
Day 1 of each treatment period, subjects will abstain from water 1 hour before and after dosing 
(except for water given with the dose).  Subjects will remain fasting for approximately 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 in Period 1, and whilst resident at the CRU.

H8H-MC-LAHU(c) Clinical Pharmacology Protocol
Page 25
LY573144
Alcohol – Subjects will not consume alcohol for 48 hours prior to admission in Period 1, and 
whilst resident at the CRU.  At all other times, subjects must consume no more than 2 units per 
day (1 unit = 12 oz or 360 mL of beer; 5 oz or 150 mL of wine; 1.5 oz or 45 mL of distilled 
spirits).
Tobacco – Subjects will refrain from smoking from 3 months prior to screening until discharge 
from the study.  
Grapefruit – Subjects will refrain from consuming grapefruit and grapefruit-containing products 
from 7 days prior to Day 1 in Period 1, and until study discharge.
6.3.3. Activity
No strenuous exercise will be allowed for 48 hours prior to admission in each treatment period 
until after the follow-up visit.
6.4.

explaining the correct use of the investigational product(s) 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 200 mg of active ingredient and is provided as bulk supplies in 
bottles.  Sumatriptan will be sourced by the investigative site.
Both lasmiditan and sumatriptan tablets are round and 10 mm in diameter.  Placebo tablets look 
similar to both lasmiditan and sumatriptan tablets, but contain no active ingredient.  Placebo 
tablets will be provided in similar bulk bottles as lasmiditan.
The investigational product will be labeled according to the country’s regulatory requirements.
7.2.
Method of Treatment Assignment
All subjects will participate in 4 treatment periods.  The treatments are as follows:

H8H-MC-LAHU(c) Clinical Pharmacology Protocol
Page 27
LY573144

Treatment A:  lasmiditan 200 mg + sumatriptan 100 mg

Treatment B:  lasmiditan 200 mg + placebo

Treatment C:  sumatriptan 100 mg + placebo

Treatment D:  placebo + placebo
Each subject will be randomized to one of 4 treatment sequences in a William’s square design 
(i.e., ABCD, BCDA, CDAB, and DABC) using a computer-generated allocation schedule.
7.2.1. Timing of Doses
The doses will be administered at approximately the same time on Day 1 of each treatment 
period.  The actual time of all dose administrations will be recorded in the subject’s electronic 
case report form (eCRF).
7.3.
Blinding
Each subject will either be blindfolded at each dosing occasion, or will receive the study drug in 
an amber vial, to maintain the study blind.  Blinding will also be maintained throughout the 
conduct of the study as described in the separate Blinding Plan.
Emergency codes will be available to the investigator.  A code, which reveals the treatment 
sequence 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 (CRP) 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.

H8H-MC-LAHU(c) Clinical Pharmacology Protocol
Page 28
LY573144
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 
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
In general, concomitant medication should be avoided; however, acetaminophen (maximum 
2 g/24 hours) may be administered at the discretion of the investigator for treatment of headaches 
etc.  Contraceptive medication is permitted as per the inclusion criteria.  Hormone replacement 
therapy is also allowed.
If the need for concomitant medication (other than acetaminophen, hormonal contraception, or 
HRT) 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.
Treatment After the End of the Study
Not applicable.

8. Discontinuation Criteria
Subjects discontinuing from the study prematurely for any reason must complete AE and 
follow-up procedures per Section 2 of this protocol.
Subjects who do not complete the study will not be replaced.
8.1.
Discontinuation from Study Treatment
Discontinuation of the investigational product for abnormal liver tests should be considered by 
the investigator when a subject meets 1 of the following conditions after consultation with the 
Lilly-designated medical monitor:

alanine aminotransferase (ALT), aspartate aminotransferase (AST) >5X upper limit of 
normal (ULN)

ALT or AST >3X ULN and total bilirubin >2X ULN or international normalized ratio
(INR) >1.5

ALP>2.5X ULN and total bilirubin >2X ULN

ALP>2.5X ULN with the appearance of fatigue, nausea, vomiting, right quadrant pain or 
tenderness, fever, rash, and/or eosinophilia (>5%)
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 subject may continue in the study.  If both agree 
it is medically appropriate to continue, the investigator must obtain documented approval from 
the Lilly clinical pharmacologist/CRP or designee to allow the inadvertently enrolled subject to 
continue in the study with or without continued treatment with investigational product.  
8.2.
Discontinuation from the Study
Subjects will be discontinued in the following circumstances:

Enrollment in any other clinical study involving an investigational product or enrollment 
in any other type of medical research judged not to be scientifically or medically 
compatible with this study

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)


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 eCRF, the 
occurrence and nature of each subject’s preexisting conditions, including clinically significant 
signs and symptoms.  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 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.

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 subject or may require intervention to prevent 
one of the other outcomes listed in the definition above.
Study site personnel must alert the Lilly clinical pharmacologist/CRP, 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 eCRF 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) 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 investigational product or procedure. Lilly 
has procedures that will be followed for the recording and expedited reporting of SUSARs that 
are consistent with global regulations and the associated detailed guidances.

H8H-MC-LAHU(c) Clinical Pharmacology Protocol

LY573144
9.2.2. Complaint Handling
Lilly collects product complaints on investigational products and drug delivery systems used in 
clinical trials in order to ensure the safety of study participants, monitor quality, and to facilitate 
process and product improvements.
Complaints pertaining to lasmiditan in this study will be collected.  As sumatriptan will be 
commercially supplied, Lilly will not collect product complaints on sumatriptan in this study.
Subjects should be instructed to contact the investigator as soon as possible if he or she has a 
complaint or problem with lasmiditan so that the situation can be assessed.
9.3.
Treatment of Overdose
For the purposes of this study, an overdose of lasmiditan or sumatriptan is considered any dose 
higher than the dose assigned through randomization.  There is no specific antidote for 
lasmiditan or sumatriptan.  In the event of overdose, the subject should receive appropriate 
supportive care and AEs should be documented.
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 investigational product should be reported to Lilly or 
its designee as an AE via eCRF.
9.4.2. Vital Signs
9.4.2.1.
Supine and Orthostatic Vital Signs
For each subject, supine and orthostatic vital signs measurements should be conducted according 
to the Schedule of Activities (Section 2).  
Blood pressure and PR should be measured singly after at least 5 minutes supine.  For each 
individual subject, the same cuff size should be used throughout the study for the measurements 
of BP.  The cuff should be attached to the subject’s dominant arm.
Where orthostatic measurements are required, subjects should be supine for at least 5 minutes 
and then subjects will stand, and standing blood pressure will be measured after 2 minutes; no 
longer than 3 minutes. 
If the subject 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 treatment period if warranted.

H8H-MC-LAHU(c) Clinical Pharmacology Protocol
Page 34
LY573144
9.4.2.2.
Ambulatory Blood Pressure Monitoring
For each subject, ABPM will be performed according to the Schedule of Activities (Section 2).
Site investigative personnel should be trained on the correct positioning of the ABPM monitor, 
use of correct cuff size, and monitor calibration prior to the start of the study.  Subjects should be
trained on the ABPM device before the predose measurement in the first treatment period to 
maximize the collection of valid measurements, and to alleviate any concerns about 
inconvenience due to the continuous 24-hour monitoring.
The ABPM device should be attached to the subject’s nondominant arm and will record 
ambulatory BP and PR every 20 minutes during awake hours (for example, 0700 hours to 
2200 hours) and every 30 minutes throughout the night (2200 hours to 0700 hours).  On Day 1 of 
each treatment period, the BP and PR recording will be initiated approximately 2 hours prior to 
the planned dosing time and will continue for approximately 26 hours. Subjects will be 
encouraged to keep the same routine without strenuous activity during the ABPM recording 
days.
The ABPM device should be removed from each subject prior to their discharge from the CRU.
9.4.3. Electrocardiograms
For each subject, single 12-lead digital safety ECGs should be collected according to the 
Schedule of Activities (Section 2).  Electrocardiograms may be obtained at additional times, 
when deemed clinically necessary.
Any clinically significant findings from ECGs that result in a diagnosis and that occur after the 
subject receives the first dose of the investigational, should be reported to Lilly, or its designee, 
as an AE via eCRF.
Electrocardiograms must be recorded before collecting any blood samples.  Subjects must be 
supine for at least 5 to 10 minutes before ECG collection and remain supine but awake during 
ECG collection.  All ECGs 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 whilst the 
subject is still present, to determine whether the subject meets entry criteria at the relevant 
visit(s) and for immediate subject management, should any clinically relevant findings be 
identified.
If a clinically significant quantitative or qualitative change from baseline is identified after 
enrollment, the investigator will assess the subject for symptoms (for example, palpitations, near 
syncope, syncope) to determine whether the subject can continue in the study.  The investigator 
or qualified designee is responsible for determining if any change in subject management is 
needed and must document his/her review of the ECG printed at the time of evaluation from at 
least 1 of the replicate ECGs from each time point.

LY573144
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
When appropriate, the Lilly clinical pharmacologist or CRP will consult with the functionally 
independent Global Patient Safety therapeutic area physician or clinical research scientist.
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, total bilirubin, 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. 
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 total bilirubin 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 

subject discontinued from treatment due to a hepatic event or abnormality of liver 
tests

hepatic event considered to be an SAE.
9.5.
Pharmacokinetics
At the visits and times specified in the Schedule of Activities, venous blood samples of 
approximately 2 mL each will be collected to determine the plasma concentrations of lasmiditan, 
and its metabolites, and 3 mL each to determine the plasma concentrations of sumatriptan.  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.

H8H-MC-LAHU(c) Clinical Pharmacology Protocol
Page 36
LY573144
9.5.1. Bioanalysis
Samples will be analyzed at a laboratory approved by the sponsor and stored at a facility 
designated by the sponsor.
Concentrations of lasmiditan and its metabolites will be assayed using a validated liquid 
chromatography with tandem mass spectrometric detection (LC-MS/MS) method.  
Concentrations of sumatriptan will be assayed using a validated LC-MS/MS method.
Bioanalytical samples collected to measure investigational product concentrations will be 
retained for a maximum of 2 years following last subject visit for the study.  During this time, 
samples remaining after the bioanalyses may be used for exploratory analyses such as 
metabolism and/or protein binding work.
9.6.
Pharmacodynamics
Not applicable.
9.7.
Genetics
A 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 exposure or 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.  
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. 
9.8.
Biomarkers
9.8.1. Creatinine Clearance
Urine samples (relative to the dosing time of lasmiditan) will be collected according to the 
Schedule of Activities (Section 2) to determine creatinine clearance. The collection will start at 

H8H-MC-LAHU(c) Clinical Pharmacology Protocol
Page 37
LY573144
the time of dosing on Day 1 and will be completed on Day 3 of each treatment period.  The 
actual volume of urine collected and the time of each collection will be recorded.
Creatinine urine samples, together with the serum creatinine measurements, will be used to 
assess creatinine clearance.
The sample(s) will be stored per institutional standards at a facility selected by the sponsor.  
During this time, remaining samples may be used for exploratory analyses.
9.8.2. Renal Biomarker Samples
Analysis will be performed on renal function biomarkers, including, but not limited to, creatinine 
and cystatin C, to evaluate any changes from baseline (predose) following lasmiditan dosing.  
Venous blood samples will be collected as specified in the Schedule of Activities (Section 2) for 
determination of serum concentrations of creatinine and cystatin C.
The samples will be identified by subject numbers and stored for a maximum of 2 years after the 
last subject visit for the study.

10. Statistical Considerations and Data Analysis
10.1.Sample SizeDetermination
Up to 40 subjects may be enrolled to ensure 30 subjects complete the study.Assuming standard 
deviation for the change, within-subject, in SBPof 12.7 mmHg (based on results from study 
), this will result in a 90% probability that the half-width of the 90% confidence 
interval (CI) about the mean within-subject change between periods is no larger than 4.6 mmHg.
10.2.Populations for Analyses
10.2.1.Study Participant Disposition
A detailed description of subject disposition will be providedat 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.
Cardiovascular analyseswill be conducted on data from all subjects who have the relevant test 
and reference treatment measurements.
Pharmacokinetic analyses will be conducted on data from all subjects who receiveat least one 
dose of lasmiditan or sumatriptanand 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 PKanalysis purposes to 
avoid issues with post-hoc analyses and incomplete disclosures of analyses.  
10.3.1.Safety Analyses
10.3.1.1.Clinical Evaluation of Safety
CCI
All investigational productand protocol procedure AEs will be listed, and if the frequency of 
events allows, safety data will be summarized using descriptive methodology.
The incidence of symptoms for each treatment will be presented by severity and by association 
with investigational productas 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.

H8H-MC-LAHU(c) Clinical Pharmacology Protocol
Page 39
LY573144
The number of investigational product-related SAEs will be reported.
10.3.1.2. Statistical Evaluation of Safety
Clinical laboratory and vital signs parameters will be listed and summarized using standard 
descriptive statistics.  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, its metabolites, and sumatriptan will be 
calculated by standard noncompartmental methods of analysis and summarized using descriptive 
statistics.
The primary parameters for analysis will be Cmax, tmax, AUC(0-tlast), and AUC(0-∞) of 
lasmiditan, its metabolites, and sumatriptan.  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 the impact of a single dose of 
sumatriptan 100 mg on the PK of lasmiditan and its metabolites.  Log-transformed Cmax and 
AUC parameters will be evaluated using a linear effects model with fixed effects for treatment, 
period (1, 2, 3, or 4) and treatment sequence, and a random effect for subject.  From this model, 
the 90% CIs of the ratios of geometric means from Treatment A (lasmiditan + sumatriptan) will 
be determined and presented versus those of Treatment B (lasmiditan + placebo).  
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.  
The same model will be independently used to assess the impact of a single dose of lasmiditan 
200 mg on the PK of sumatriptan.
Additional analyses may be performed, as warranted.
10.3.3. Cardiovascular Analyses
10.3.3.1. Cardiovascular Parameter Estimation
The primary parameters for the cardiovascular analyses will be peak hourly mean values of SBP, 
DBP, and MAP, and nadir hourly mean value of PR, and will be determined by ABPM.
10.3.3.2. Statistical Inference of Cardiovascular Parameters
Cardiovascular parameters will be listed, and summarized using descriptive statistics, as 
appropriate.  
Baseline value will be defined as the mean value during the 2 hours pre-dose for each period.  
Changes from baseline in cardiovascular parameters SBP, DBP, MAP, and PR will be analyzed 
to determine the impact of a single dose of sumatriptan 100 mg on the cardiovascular parameters

H8H-MC-LAHU(c) Clinical Pharmacology Protocol

LY573144
of lasmiditan. A repeated measures linear mixed-effects model with baseline as a covariate, 
fixed effects for time point, treatment, period (1, 2, 3, or 4), treatment sequence, and the 
treatment by time point interaction, and a random effect for subject will be used. Least squares 
(LS) means and treatment differences ([lasmiditan + sumatriptan] - [lasmiditan + placebo]) will 
be calculated and presented with the corresponding CIs. The same model will be used to assess 
the impact of a single dose of lasmiditan 200 mg on the cardiovascular parameters of 
sumatriptan.
10.3.4. Biomarker Analyses
Exploratory biomarkers such as creatinine clearance, as well as creatinine and cystatin C levels 
may be listed, and summarized using descriptive statistics.
Additional analysis may be performed if warranted upon review of the data.
10.3.5. 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.

Protocol Amendment H8H-MC-LAHU(c) 
Summary:  A Randomized, Double-Blind, Four-Period, 
Crossover Study to Evaluate the Cardiovascular Effect 
of Single Oral Doses of Lasmiditan when 
Coadministered with Single Oral Doses of Sumatriptan 
in Healthy Subjects
Overview
Protocol H8H-MC-LAHU, A Randomized, Double-Blind, Four-Period, Crossover Study to 
Evaluate the Cardiovascular Effect of Single Oral Doses of Lasmiditan when Coadministered 
with Single Oral Doses of Sumatriptan in Healthy Subjects, has been amended.  The new 
protocol is indicated by Amendment (c) and will be used to conduct the study in place of any 
preceding version of the protocol.
Following feedback from the FDA from the Type C meeting on 12 October 2017, the protocol 
was amended to include an assessment on lasmiditan metabolites. In addition, language was 
added to clarify the definitions of peak, nadir, and baseline for ABPM.

1. Protocol Synopsis
Statistical Analysis:
Cardiovascular parameters that will be assessed by ABPM include peak hourly mean values of SBP, DBP, and 
MAP, and nadir hourly mean value of PR.  The parameters will be listed, and summarized using descriptive 
statistics, as appropriate. Changes from baseline in cardiovascular parameters SBP, DBP, MAP, and PR will be 
analyzed to determine the impact of a single dose of sumatriptan 100 mg on the cardiovascular parameters of 
lasmiditan. A repeated measures linear mixed-effects model with baseline as a covariate, fixed effects for time 
point, treatment, period (1, 2, 3, or 4), treatment sequence and the treatment by time point interaction, and a random 
effect for subject will be used. Least squares (LS) means and treatment differences ([lasmiditan + sumatriptan] -
[lasmiditan + placebo]) will be calculated and presented with the corresponding confidence intervals (CIs). The 
same model will be used to assess the impact of a single dose of lasmiditan 200 mg on the cardiovascular parameters
of sumatriptan.
Pharmacokinetic parameter estimates for lasmiditan, its metabolites, and sumatriptan will be calculated by standard 
noncompartmental methods of analysis.  Pharmacokinetic parameter estimates will be evaluated to determine the 
impact of a single dose of sumatriptan 100 mg on the PK of lasmiditan and its metabolites.  Log-transformed Cmax
and AUC parameters will be evaluated using a linear effects model with fixed effects for treatment, period (1, 2, 3, 
or 4), and treatment sequence, and a random effect for subject.  From this model, the 90% CIs of the ratios of 
geometric means from Treatment A (lasmiditan + sumatriptan) will be determined and presented versus those of 
Treatment B (lasmiditan + placebo).  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.  The same model will be independently used to assess the impact of a single dose of lasmiditan 200 mg 
on the PK of sumatriptan.
Safety parameters that will be assessed include clinical laboratory parameters, vital signs, and 12-lead 
electrocardiogram (ECG) parameters.  The parameters will be listed, and summarized using descriptive statistics, as 
appropriate.

4. Objectives and Endpoints
Table LAHU.1.
Objectives and Endpoints
Exploratory
To evaluate the effect of lasmiditan on renal function 
biomarkers in serum and urine.
To evaluate the PK of lasmiditan metabolites alone and 
in combination with sumatriptan in healthy subjects.
Cystatin C, creatinine, and creatinine clearance.
Cmax, tmax, AUC(0-tlast) and AUC(0-∞).
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 its metabolites, and 3 mL each to determine the plasma concentrations of sumatriptan.  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.
Concentrations of lasmiditan and its metabolites will be assayed using a validated liquid 
chromatography with tandem mass spectrometric detection (LC-MS/MS) method.  
Concentrations of sumatriptan will be assayed using a validated LC-MS/MS method.

H8H-MC-LAHU(c) Clinical Pharmacology Protocol
Page 55
LY573144
Bioanalytical samples collected to measure investigational product concentrations will be 
retained for a maximum of 2 years following last subject visit for the study.  During this time, 
samples remaining after the bioanalyses may be used for exploratory analyses such as 
metabolism and/or protein binding work.
10.3.2.1. Pharmacokinetic Parameter Estimation
Pharmacokinetic parameter estimates for lasmiditan, its metabolites, and sumatriptan will be 
calculated by standard noncompartmental methods of analysis and summarized using descriptive 
statistics.
The primary parameters for analysis will be Cmax, tmax, AUC(0-tlast), and AUC(0-∞) of 
lasmiditan, its metabolites, and sumatriptan.  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 the impact of a single dose of 
sumatriptan 100 mg on the PK of lasmiditan and its metabolites.  Log-transformed Cmax and 
AUC parameters will be evaluated using a linear effects model with fixed effects for treatment, 
period (1, 2, 3, or 4) and treatment sequence, and a random effect for subject.  From this model, 
the 90% CIs of the ratios of geometric means from Treatment A (lasmiditan + sumatriptan) will 
be determined and presented versus those of Treatment B (lasmiditan + placebo).
10.3.3.1. Cardiovascular Parameter Estimation
The primary parameters for the cardiovascular analyses will be peak hourly mean values of SBP, 
DBP, and MAP, and nadir hourly mean value of PR, and will be determined by ABPM.
10.3.3.2. Statistical Inference of Cardiovascular Parameters
Cardiovascular parameters will be listed, and summarized using descriptive statistics, as 
appropriate.
Baseline value will be defined as the peak mean value during the 2 hours pre-dose for each 
period.  Changes from baseline in cardiovascular parameters SBP, DBP, MAP, and PR will be 
analyzed to determine the impact of a single dose of sumatriptan 100 mg on the cardiovascular 
parameters of lasmiditan. A repeated measures linear mixed-effects model with baseline as a 
covariate, fixed effects for time point, treatment, period (1, 2, 3, or 4), treatment sequence, and 
the treatment by time point interaction, and a random effect for subject will be used. Least 
squares (LS) means and treatment differences ([lasmiditan + sumatriptan] -
[lasmiditan + placebo]) will be calculated and presented with the corresponding CIs. The same 
model will be used to assess the impact of a single dose of lasmiditan 200 mg on the 
cardiovascular parameters of sumatriptan.
