Overall Design
Screening
All participants will be screened within 28 days prior to enrollment. 
Treatment and Assessment Period
Eligible participants will take part in 3 separate dosing periods. In each period, participants will 
be admitted to the clinical research unit (CRU) on Day -1 and remain resident in the CRU until 
discharge on Day 6. 
There will be a washout period of ≥5 days between the day of dosing in 1 period and the day of 
dosing in the subsequent period. Days 5 and 6 of Period 1 and 2 may coincide with Days -1 and 
1 of Period 2 and 3, respectively, provided the required washout between lasmiditan doses is 
observed. 
On Day 1 of Period 1, participants will be equally randomized to receive a 100-mg oral dose in 
1 of 6 dosing sequences in each of 3 dosing periods. 
Pharmacokinetic blood sampling and safety assessments, including vital sign measurements,
physical examinations, clinical laboratory tests, electrocardiograms, and adverse event recording 
will be performed according to the Schedule of Activities.
Follow-up
Day 6 of Period 3 will be considered the final visit of the study. 
Disclosure Statement: This is a Phase 1, open-label, randomized, single-dose, 3-way crossover 
study, with 6 sequences in healthy participants.
Number of Participants: Approximately 48 participants will be enrolled to ensure that 
36 participants, 6 per treatment sequence, complete the study.
Intervention Groups and Duration: Participants will receive single 100-mg doses of lasmiditan 
in each of 3 dosing periods, according to 1 of the randomized sequences detailed below.

Introduction
Lasmiditan (LY573144) has been developed by Eli Lilly and Company (Lilly), and approved by 
the Food and Drug Administration (FDA), for the acute treatment of migraine with or without 
aura in adults. Full details of the preclinical and clinical safety and tolerability data are contained 
in the Investigator’s Brochure (IB).  
2.1.
Study Rationale
Previous clinical studies of lasmiditan have used an immediate-release (IR) tablet formulation. 
An oral-disintegrating (OD) tablet has been developed to support pediatric development and for 
more convenient administration in adults, e.g., for those who have difficulty swallowing a tablet.  
This study is intended to determine the bioequivalence, safety, and tolerability of a newly
developed OD tablet of lasmiditan compared to the current IR tablet. Information on the 
acceptability and palatability of the OD tablet will also be collected during the study. 
2.2.
Background
Lasmiditan is a low-molecular-weight agonist of the 5-hydroxytryptamine (5-HT)1F receptor 
with a nonvascular and primarily neural mechanism of action. It has a high affinity for the 
human 5-HT1F receptor and a >440-fold selectivity for the human 5-HT1F receptor relative to the 
5-HT1B receptor. Lasmiditan has high solubility and permeability.
Lasmiditan doses have been evaluated in healthy participants or patients with migraine across 
completed Phase 1, 2, and 3 clinical studies. Across these studies, single intravenous and single 
oral doses of lasmiditan were administered over a range of 0.1 mg to 400 mg. Multiple oral doses 
of 200 mg or 400 mg were administered orally once daily (QD) for 7 days. Cumulatively through 
14 August 2018, approximately 4945 participants have received lasmiditan. The most frequently 
reported lasmiditan adverse events (AEs) in the 2 Phase 3 placebo-controlled studies, in which 
patients treated 1 migraine attack with oral lasmiditan (50, 100, or 200 mg) or placebo, were 
dizziness, paresthesia, somnolence, fatigue, and nausea, and the majority were mild or moderate 
in severity. Safety and tolerability in healthy participants were similar up to the highest dose of 
400 mg administered as a single and multiple (QD for 7 days) dose, with drowsiness, dizziness, 
and paresthesia being the most frequently reported AEs. The majority of these were mild in 
severity, and none were severe.
In previous studies, following single oral dose administration of lasmiditan to healthy 
participants, lasmiditan was absorbed with a median time of maximum observed drug 
concentration (tmax) of 1.8 hours, and rapidly eliminated with a mean terminal half-life (t1/2) of 
approximately 5.7 hours. Lasmiditan exposure increased in a dose-dependent manner that was 
considered to be approximately linear with dose over a clinical dose range of 50 to 200 mg. No 
accumulation of lasmiditan was previously observed with repeated QD dosing of 200 or 400 mg. 
Lasmiditan undergoes extensive hepatic and extrahepatic metabolism with ketone reduction to 
inactive metabolite 8 (M8) as the major biotransformation pathway.

Protocol H8H-MC-LAIA

2.3.
Benefit/Risk Assessment
There is no anticipated therapeutic benefit for the healthy participants.
A 100-mg dose of lasmiditan will be used in the current study. Oral doses of lasmiditan up to the 
highest single and multiple oral dose given (400 mg) were well tolerated in healthy participants, 
with no drug-related serious adverse events (SAEs) or withdrawals due to AEs as of 14 August 
2018. Lasmiditan caused no significant QT prolongation either at 100 or 400 mg, and no 
clinically significant changes in clinical laboratory data. Lasmiditan has been associated with a 
mean decrease in heart rate of 5 to 10 bpm compared to 2 to 5 bpm for placebo. Additionally, in 
non-elderly healthy volunteers, a mean increase in blood pressure of approximately 2 to 3 mmHg 
was observed 1 hour after dosing with 200 mg lasmiditan. There were no additional findings on 
vital signs following QD dosing for 7 days. Overall, in previous healthy volunteer studies, these 
changes were well tolerated. Although central nervous system disorders were commonly 
reported as AEs, especially at higher dose levels, they were generally mild or moderate in 
intensity.  
Participants should avoid driving or operating machinery for at least 8 hours following dosing 
with lasmiditan. This risk is mitigated in the current study as participants will be confined to the 
clinical research unit (CRU).
More detailed information about the known and expected benefits and risks and reasonably 
expected AEs of lasmiditan may be found in the IB.

Study Design
4.1.
Overall Design
Study H8H-MC-LAIA (LAIA) is a Phase 1, open-label, randomized, single-dose, 3-way 
crossover study in healthy participants. Approximately 48 participants will be enrolled such that 
36 participants, 6 per treatment sequence, complete the study.
Screening
All participants will be screened within 28 days prior to enrollment. 
Treatment and Assessment Period
Eligible participants will take part in 3 separate dosing periods. In each period, participants will 
be admitted to the CRU on Day -1 and remain resident in the CRU until discharge on Day 6. At 
the discretion of the investigator, participants may remain resident in the CRU for the entirety of 
the study, i.e., from admission to the CRU on Day -1 of Period 1 until discharge from the CRU 
on Day 6 of Period 3, after all assessments have been completed. 
There will be a washout period of ≥5 days between the day of dosing in 1 period and the day of 
dosing in the subsequent period. Days 5 and 6 of Period 1 and 2 may coincide with Days -1 
and 1 of Period 2 and 3, respectively, provided the required washout between lasmiditan doses is 
observed. 
On Day 1 of Period 1, participants will be equally randomized to receive a 100-mg oral dose in 
1 of 6 dosing sequences in each of 3 dosing periods as shown in Table LAIA.1.

4.2.
Scientific Rationale for Study Design
In order to minimize any potential period effect and to allow each participant to act as his/her 
own control, a randomized, 3-sequence, crossover design has been selected.
Based on the t1/2 of lasmiditan and its metabolites, at least 5 days between the day of dosing in 
1 period and the day of dosing in the subsequent period is considered sufficient time for the 
study drug to washout.  
Conducting the study in healthy participants mitigates the potential confounding effects of the
disease state and concomitant medications in participants with migraine. A population of healthy 
participants is frequently used in the assessment of the pharmacokinetics (PK) of both small and 
large molecules.
This study will be open label as the study primary endpoint PK measures are objective rather
than subjective.
4.3.
Justification for Dose
An oral dose of 100 mg lasmiditan is a clinically effective dose for the target population, based 
on data obtained from previous completed studies. 
Previous studies in healthy participants have shown single doses of lasmiditan up to 400 mg are 
generally safe and well tolerated. 
4.4.
End of Study Definition
A participant is considered to have completed the study if he/she has completed all required 
phases of the study including the last scheduled procedure shown in the SoA (Section 1.3).
The end of the study is defined as the date of the last visit of the last participant in the study.

Study Population
Eligibility of participants for enrollment in 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.
The inclusion and exclusion criteria used to determine eligibility should be applied at screening 
only and at the discretion of the investigator through predose Day 1 (Period 1 only) for safety, 
not continuously throughout the trial.
Screening may occur up to 28 days prior to enrollment. Participants who are not enrolled within 
28 days of screening may undergo an additional medical assessment and/or clinical 
measurements to confirm their eligibility. In such instances, repeat the following screening tests 
and procedures: weight, vital signs, ECG, clinical laboratory tests, and pregnancy test (females 
only).  
Prospective approval of protocol deviations to recruitment and enrollment criteria, also known as 
protocol waivers or exemptions, is not permitted

Administration Details
Participants will be equally randomized to 1 of 6 dosing sequences in each of 3 dosing periods as 
described in Section 4.1.
For each dosing period, participants will receive a single oral dose on the morning of Day 1.  

IR tablet: Participants receiving the IR tablet formulation will swallow the tablet with 
240 mL of room-temperature water.  

OD tablet (without water): Immediately before dose administration participants 
receiving the OD tablet formulation without water will receive 20 mL of room-
temperature water to wet their palettes. Then using a dry hand, participants will place the 
OD tablet on top of the tongue and keep it there until it disintegrates. A gentle pressure 
may be exerted on the tablet by pressing the tongue against the roof of the mouth to 
facilitate disintegration of the tablet. The participants will then fully swallow the saliva 
containing both disintegrated and any un-disintegrated remaining part of the tablet.

OD tablet (with water): Immediately before dose administration participants receiving 
the OD tablet formulation with water will receive 20 mL of room-temperature water to 
wet their palettes. Then using a dry hand, participants will place the OD tablet on top of 
the tongue and keep it there until it disintegrates. A gentle pressure may be exerted on the 

CONFIDENTIAL
Protocol H8H-MC-LAIA
22
tablet by pressing the tongue against the roof of the mouth to facilitate disintegration of 
the tablet. Once the tablet has disintegrated, the participants will then drink 240 mL of 
room-temperature water and swallow with the saliva containing both disintegrated and 
any un-disintegrated remaining part of the tablet.
All doses will be administered in a sitting position and participants will not be allowed to lie 
supine for 2 hours after dosing, unless clinically indicated or for study procedures.
6.2.
Preparation/Handling/Storage/Accountability
1. The investigator or designee must confirm appropriate temperature conditions have been 
maintained during transit for all study intervention received and any discrepancies are 
reported and resolved before use of the study intervention.
2. Only participants enrolled in the study may receive study intervention and only 
authorized site staff may supply or administer study intervention. All study intervention 
must be stored in a secure, environmentally controlled, and monitored (manual or 
automated) area in accordance with the labeled storage conditions with access limited to 
the investigator and authorized site staff.
3. The investigator, institution, or the head of the medical institution (where applicable) is 
responsible for study intervention accountability, reconciliation, and record maintenance 
(i.e., receipt, reconciliation, and final disposition records).
4. The investigator or designee will return all unused study interventions to Lilly or its 
designee at the end of the study. In some cases, sites may destroy the material if, during 
the CRU selection, the evaluator has verified and documented that the site has 
appropriate facilities and written procedures to dispose of clinical materials.
6.3.
Measures to Minimize Bias: Randomization and Blinding
This is an open-label study; potential bias will be reduced by central randomization.
On Day 1 of Treatment Period 1, participants will be assigned a unique number (randomization 
number). The randomization number encodes the participant’s assignment to 1 of 6 treatment 
sequences, according to the randomization schedule generated prior to the study by the Statistics 
Department at Covance. Each participant will be dispensed study intervention, labeled with 
his/her unique randomization number, throughout the study.
6.4.
Study Intervention Compliance
Participants are dosed at the site and they will receive study intervention directly from the 
investigator or designee, under medical supervision. The date and time of each dose administered 
in the clinic will be recorded in the source documents and recorded in the electronic case report 
form (eCRF). The dose of study intervention and study participant identification will be 
confirmed at the time of dosing by a member of the study site staff other than the person 
administering the study intervention. Study site personnel will examine each participant’s mouth 
to ensure that the study intervention was ingested.

Concomitant Therapy
Participants must abstain from taking prescription or nonprescription drugs (including dietary
supplements) within 14 days prior to dosing and until study discharge, unless, in the opinion of 
the investigator and sponsor, the medication will not interfere with the study.
Acetaminophen, at doses of 3 g/24 hours, is permitted for use at the discretion of the 
investigator for the treatment of headache etc. Contraceptive medication is permitted as per the 
contraception requirements (Section 10.4) and hormone-replacement therapy is also allowed.

AE and other follow-up/early discontinuation procedures as per the SoA (Section 1.3).
Participants discontinuing from the study prematurely for any reason must complete AE and 
follow-up/early discontinuation procedures as per the SoA (Section 1.3).
Discontinuation of specific sites or of the study as a whole is described in Appendix 1 
(Section 10.1.7).
7.1.
Discontinuation of Study Intervention
Discontinuation of the study drug for abnormal liver tests should be considered by the 
investigator when a participant meets 1 of the following conditions after consultation with the 
Lilly-designated medical monitor:

alanine aminotransferase (ALT) or aspartate aminotransferase (AST) >5 × upper limit of 
normal (ULN)

ALT or AST >3 × ULN sustained for more than 2 weeks

ALT or AST >3 × ULN and total bilirubin level (TBL) >2 × ULN or international 
normalized ratio >1.5

ALT or AST >3 × ULN and the appearance of fatigue, nausea, vomiting, right 
upper-quadrant pain or tenderness, fever, rash, and/or eosinophilia (>5%).
7.2.
Participant Discontinuation/Withdrawal from the Study
A participant may withdraw from the study:

at any time at his/her own request 

at the request of his/her designee (for example, parents or legal guardian)

at the discretion of the investigator for safety, behavioral, compliance, or 
administrative reasons

if the participant becomes pregnant during the study

if 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.
Discontinuation is expected to be uncommon.
At the time of discontinuing from the study, if possible, an early discontinuation visit should be 
conducted, as shown in the SoA (Section 1.3). See SoA for data to be collected at the time of 
study discontinuation and follow-up and for any further evaluations that need to be completed.
The participant will be permanently discontinued both from the study intervention and from the 
study at that time.

CONFIDENTIAL
Protocol H8H-MC-LAIA

If the participant withdraws consent for disclosure of future information, the sponsor may retain 
and continue to use any data collected before such a withdrawal of consent. If a participant
withdraws from the study, he/she may request destruction of any samples taken and not tested,
and the investigator must document this in the site study records.
7.2.1.
Discontinuation of Inadvertently Enrolled Participants
If the sponsor or investigator identify a participant who did not meet enrollment criteria and was 
inadvertently enrolled, then the participant should be discontinued from study treatment unless 
there are extenuating circumstances that make it medically necessary for the participant to 
continue on study treatment. If the investigator and the sponsor CRP agree it is medically 
appropriate to continue, the investigator must obtain documented approval from the sponsor CRP 
to allow the inadvertently enrolled participant to continue in the study with or without treatment 
with investigational product. Safety follow-up is as outlined in Section 1.3 (SoA), Section 8.2
(Safety Assessments), and Section 8.3 (Adverse Events and Serious Adverse Events) of the 
protocol.
7.3.
Lost to Follow-up
A participant will be considered lost to follow-up if he or she repeatedly fails to return for 
scheduled visits and is unable to be contacted by the study site. Site personnel are expected to 
make diligent attempts to contact participants who fail to return for a scheduled visit or were 
otherwise unable to be followed up by the site.

Study Assessments and Procedures
Study procedures and their timings are summarized in the SoA (Section 1.3).
Protocol waivers or exemptions are not allowed.
Immediate safety concerns should be discussed with the sponsor immediately upon occurrence or 
awareness to determine if the participant should continue or discontinue study intervention.
Adherence to the study design requirements, including those specified in the SoA, is essential 
and required for study conduct.
All screening evaluations must be completed and reviewed to confirm that potential participants 
meet all eligibility criteria. The investigator will maintain a screening log to record details of all 
participants screened and to confirm eligibility or record reasons for screening failure, as 
applicable.
Appendix 2 (Section 10.2) lists the laboratory tests that will be performed for this study.
Appendix 2 (Section 10.2.1) 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.
Assessment collection time
The specifications in this protocol for the timings of safety and sample collection are given as 
targets to be achieved within reasonable limits. Modifications may be made to the time points 
based upon emerging clinical information. The scheduled time points may be subject to minor 
alterations; however, the actual time must be correctly recorded in the eCRF. Failure or being 
late (that is, outside stipulated time allowances) to perform procedures or obtain samples within 
the stipulated time allowances due to legitimate clinical issues (for example, equipment technical 
problems, venous access difficulty) will not be considered protocol deviations. However, the 
CRU is required to notify the sponsor in writing using a file note.

Efficacy Assessments
Efficacy is not evaluated in this study.
8.2.
Safety Assessments
Planned time points for all safety assessments are provided in the SoA (Section 1.3).
8.2.1.
Physical Examinations
A complete physical examination will include, at a minimum, assessments of the cardiovascular, 
respiratory, gastrointestinal, and neurological systems. Height and weight will also be measured 
and recorded.
Investigators should pay special attention to clinical signs related to previous illnesses.

CONFIDENTIAL
Protocol H8H-MC-LAIA
27
Additional symptom-driven physical examinations may be performed at the discretion of the 
investigator.
Any clinically significant findings in a physical examination should be reported as AEs.
8.2.2.
Vital Signs
For each participant, vital signs measurements should be conducted according to the SoA
(Section 1.3).
Blood pressure and pulse rate should be measured after at least 5 minutes supine. For each 
individual participant, the same cuff size should be used throughout the study for the 
measurements of blood pressure. The cuff should be attached to the participant’s dominant arm.
Unscheduled orthostatic vital signs should be assessed, if possible, during any AE of dizziness or 
posture-induced symptoms. Where orthostatic measurements are required, participants should be 
supine for at least 5 minutes and stand for at least 2 minutes, but no longer than 3 minutes. If the 
participant feels unable to stand, supine vital signs only will be collected. 
Additional vital signs may be measured during each dosing period if warranted and agreed upon 
between Lilly and the investigator.
8.2.3.
Electrocardiograms
For each participant, a single 12-lead digital ECG will be collected as outlined in the SoA 
(Section 1.3).
Electrocardiograms must be recorded before collecting any blood samples. Participants must be 
supine for approximately 5 to 10 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 
participant is still present, to determine whether the participant meets entry criteria at the relevant 
visits and for immediate participant management, should any clinically relevant findings be 
identified. 
If a clinically significant finding is identified (including, but not limited to, changes in 
QT/corrected QT interval from baseline) after enrollment, the investigator will determine if the 
participant can continue in the study. The investigator, or qualified designee, is responsible for 
determining if any change in participant 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 AE.
8.2.4.
Clinical Safety Laboratory Assessments
See Appendix 2 (Section 10.2) for the list of clinical laboratory tests to be performed and the 
SoA for the timing and frequency.
The laboratory reports must be filed with the source documents. 

CONFIDENTIAL
Protocol H8H-MC-LAIA
28
The investigator must review the laboratory report, document this review, and record any 
clinically relevant changes occurring during the study in the AE section of the eCRF. 
All laboratory tests with values considered clinically significantly abnormal during participation 
in the study should be repeated until the values return to normal or baseline or are no longer 
considered clinically significant by the investigator or Lilly CP.

If such values do not return to normal/baseline within a period of time judged reasonable 
by the investigator, the etiology should be identified and the sponsor notified.

All protocol-required laboratory assessments, as defined in Appendix 2 (Section 10.2), 
must be conducted in accordance with the laboratory manual and the SoA (Section 1.3).

If laboratory values from non-protocol-specified laboratory assessments performed at the 
institution’s local laboratory require a change in participant management or are 
considered clinically significant by the investigator (e.g., SAE or AE), then the results 
must be recorded in the eCRF.
8.2.5.
Safety Monitoring
The Lilly CP or CRP will monitor safety data throughout the course of the study.
Lilly will review SAEs within time frames mandated by company procedures (Section 8.3.1). 
The Lilly CP or CRP will periodically review:

trends in safety data

laboratory analytes 

AEs.
When appropriate, the Lilly CP or CRP will consult with the functionally independent Global 
Patient Safety medical physician or clinical research scientist.
8.2.5.1.
Hepatic Safety
Close hepatic monitoring
Laboratory tests (Appendix 6, Section 10.6), including ALT, AST, alkaline phosphatase (ALP), 
and TBL, should be repeated, with the addition of direct bilirubin, gamma-glutamyl transferase, 
and creatine kinase, within 48 to 72 hours to confirm the abnormality and to determine if it is 
increasing or decreasing, if 1 or more of these conditions occur:
If a participant with baseline results of ...
develops the following elevations:
ALT or AST <1.5 × ULN
ALT or AST ≥3 × ULN
ALP <1.5 × ULN
ALP ≥2 × ULN
TBL <1.5 × ULN
TBL ≥2 × ULN (except for participants with Gilbert’s 
syndrome)
ALT or AST ≥1.5 × ULN
ALT or AST ≥2 × baseline
ALP ≥1.5 × ULN
ALP ≥2 × baseline

CONFIDENTIAL
Protocol H8H-MC-LAIA
29
TBL ≥1.5 × ULN
TBL ≥2 × baseline (except for participants with Gilbert’s 
syndrome)
If the abnormality persists or worsens, clinical and laboratory monitoring and evaluation for 
possible causes of abnormal liver tests should be initiated by the investigator in consultation with 
the Lilly-designated CP. At a minimum, this evaluation should include physical examination and 
a thorough medical history, including symptoms, recent illnesses (for example, heart failure, 
systemic infection, hypotension, or seizures), recent travel, history of concomitant medications 
(including over-the-counter), herbal and dietary supplements, history of alcohol drinking and 
other substance abuse.
Initially, monitoring of symptoms and hepatic biochemical tests should be done at a frequency of 
1 to 3 times weekly, based on the participant’s clinical condition and hepatic biochemical tests.  
Subsequently, the frequency of monitoring may be lowered to once every 1 to 2 weeks, if the 
participant’s clinical condition and laboratory results stabilize. Monitoring of ALT, AST, ALP, 
and TBL should continue until levels normalize or return to approximate baseline levels.
Comprehensive hepatic evaluation  
A comprehensive evaluation should be performed to search for possible causes of liver injury if 
one or more of these conditions occur:
If a participant with baseline results of...
develops the following elevations:
ALT or AST <1.5 × ULN
ALT or AST ≥3 × ULN with hepatic signs/symptoms*, or
ALT or AST ≥5 × ULN
ALP <1.5 × ULN
ALP ≥3 × ULN
TBL <1.5 × ULN
TBL ≥2 × ULN (except for participants with Gilbert’s syndrome)
ALT or AST ≥1.5 × ULN
ALT or AST ≥2 × baseline with hepatic signs/symptoms*, or
ALT or AST ≥3 × baseline
ALP ≥1.5 × ULN
ALP ≥2 × baseline
TBL ≥1.5 × ULN
TBL ≥1.5 × baseline (except for participants with Gilbert’s 
syndrome) 
* Hepatic signs/symptoms are severe fatigue, nausea, vomiting, right upper quadrant abdominal pain, fever, rash, and/or 
eosinophilia >5%.
At a minimum, this evaluation should include physical examination and a thorough medical 
history, as outlined above, as well as tests for prothrombin time-international normalized ratio; 
tests for viral hepatitis A, B, C, or E; tests for autoimmune hepatitis; and an abdominal imaging 
study (for example, ultrasound or computed tomography scan).  
Based on the participant’s history and initial results, further testing should be considered in 
consultation with the Lilly-designated CP, including tests for hepatitis D virus, cytomegalovirus, 
Epstein-Barr virus, acetaminophen levels, acetaminophen protein adducts, urine toxicology 
screen, Wilson’s disease, blood alcohol levels, urinary ethyl glucuronide, and serum 
phosphatidylethanol. Based on the circumstances and the investigator’s assessment of the 
participant’s clinical condition, the investigator should consider referring the participant for a 
hepatologist or gastroenterologist consultation, magnetic resonance cholangiopancreatography, 
endoscopic retrograde cholangiopancreatography, cardiac echocardiogram, or a liver biopsy.

Additional hepatic data collection in study participants who have abnormal liver test 
results during the study
Additional safety data collection in hepatic safety eCRF should be performed in study 
participants who meet 1 or more of the following conditions:  

Elevation of serum ALT to ≥5 × ULN on 2 or more consecutive blood tests (if baseline 
ALT <1.5× ULN)
o
In participants with baseline ALT ≥1.5 × ULN, the threshold is ALT ≥3 × 
baseline on 2 or more consecutive tests

Elevated serum TBL to ≥2 × ULN (if baseline TBL <1.5 × ULN) (except for cases of 
known Gilbert’s syndrome)
o
In participants with baseline TBL ≥1.5 × ULN, the threshold should be TBL ≥2 × 
baseline

Elevation of serum ALP to ≥2 × ULN on 2 or more consecutive blood tests (if baseline 
ALP <1.5 × ULN)
o
In participants with baseline ALP ≥1.5 × ULN, the threshold is ALP ≥2 × baseline 
on 2 or more consecutive blood tests

Hepatic event considered to be an SAE

Discontinuation of study drug due to a hepatic event.
Note: The interval between the 2 consecutive blood tests should be at least 2 days.
8.3.
Adverse Events and Serious Adverse Events
Adverse events will be reported by the participant (or, when appropriate, by a caregiver, 
surrogate, or the participant's legally authorized representative).
The investigator and any qualified designees are responsible for detecting, documenting, and 
recording events that meet the definition of an AE or SAE and remain responsible for following 
up AEs that are serious, considered related to the study intervention or study procedures, or that 
caused the participant to discontinue the study intervention or study (see Section 7).
Investigators are responsible for monitoring the safety of participants 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 participant.
The investigator is responsible for the appropriate medical care of participants during the study.
8.3.1.
Time Period and Frequency for Collecting AE and SAE Information
All AEs and SAEs will be collected from the signing of the ICF until participation in study has 
ended.
Adverse events that begin before the start of study intervention but after signing of the ICF will 
be recorded on the Adverse Event eCRF.
Although all AEs after signing the ICF are recorded by the site in the eCRF, SAE reporting to 
sponsor begins after the participant has signed the ICF and has received study drug. However, if 

CONFIDENTIAL
Protocol H8H-MC-LAIA
31
an SAE occurs after signing the ICF, but prior to receiving lasmiditan, it needs to be reported 
ONLY if it is considered reasonably possibly related to study procedures.
All SAEs will be recorded and reported to the sponsor or designee immediately and under no 
circumstance should this exceed 24 hours, as indicated in Appendix 3 (Section 10.3). The 
investigator will submit any updated SAE data to the sponsor within 24 hours of it being 
available.
Investigators are not obligated to actively seek AEs or SAEs after conclusion of the study 
participation. However, if the investigator learns of any SAE, including a death, at any time after 
a participant has been discharged from the study, and he/she considers the event to be reasonably 
related to the study intervention or study participation, the investigator must promptly notify the 
sponsor.
8.3.2.
Method of Detecting AEs and SAEs
The method of recording, evaluating, and assessing causality of AE and SAE and the procedures 
for completing and transmitting SAE reports are provided in Appendix 3 (Section 10.3).
Care will be taken not to introduce bias when detecting AEs and/or SAEs. Open-ended and 
non-leading verbal questioning of the participant is the preferred method to inquire about AE
occurrences.
8.3.3.
Follow-up of AEs and SAEs
After the initial AE/SAE report, the investigator is required to proactively follow each participant 
at subsequent visits/contacts. All SAEs will be followed until resolution, stabilization, the event 
is otherwise explained, or the participant is lost to follow-up (as defined in Section 7.3). Further 
information on follow-up procedures is provided in Appendix 10.3.
8.3.4.
Regulatory Reporting Requirements for SAEs
Prompt notification by the investigator to the sponsor of an SAE is essential so that legal 
obligations and ethical responsibilities towards the safety of participants and the safety of a study 
intervention under clinical investigation are met.
The sponsor has a legal responsibility to notify both the local regulatory authority and other 
regulatory agencies about the safety of a study intervention under clinical investigation. The 
sponsor will comply with country-specific regulatory requirements relating to safety reporting to 
the regulatory authority, Institutional Review Boards (IRBs)/Independent Ethics Committees 
(IECs), and investigators.
An investigator who receives an investigator safety report describing an SAE or other specific 
safety information (e.g., summary or listing of SAEs) from the sponsor will review and then file 
it along with the IB and will notify the IRB/IEC, if appropriate according to local requirements.
8.3.5.
Pregnancy
Details of all pregnancies in female participants and female partners of male participants will be 
collected after the start of study intervention and until study end.

CONFIDENTIAL
Protocol H8H-MC-LAIA
32
If a pregnancy is reported, the investigator should inform the sponsor within 24 hours of learning 
of the pregnancy and should follow the procedures outlined in Appendix 4 (Section 10.4).
Abnormal pregnancy outcomes (e.g., spontaneous abortion, fetal death, stillbirth, congenital 
anomalies, ectopic pregnancy) are considered SAEs.
Pregnancy (maternal or paternal exposure to study intervention) does not meet the definition of 
an AE. However, to fulfill regulatory requirements, any pregnancy should be reported following 
the SAE process described in Appendix 3 (Section 10.3) to collect data on the outcome for both 
mother and fetus.
8.3.6. Product Complaints
A product complaint is any written, electronic, or oral communication that alleges deficiencies 
related to the identity, quality, durability, reliability, safety, effectiveness, or performance of a 
trial intervention.
Sponsor collects product complaints on investigational products and drug delivery systems used 
in clinical studies in order to ensure the safety of study participants, monitor quality, and to 
facilitate process and product improvements.
Participants will be instructed to contact the investigator as soon as possible if he or she has a 
complaint or problem with the investigational product so that the situation can be assessed.
Note: AEs/SAEs that are associated with a product complaint will also follow the processes 
outlined in Section 8.3.3 and Appendix 3 (Section 10.3) of the protocol.
8.3.6.1.
Time Period for Detecting Product Complaints
Product complaints that result in an AE will be detected, documented, and reported to the 
sponsor during all periods of the study in which the drug is used.
If the investigator learns of any product complaint at any time after a participant has been 
discharged from the study, and such incident is considered reasonably related to a drug provided 
for the study, the investigator will promptly notify the sponsor.
8.3.6.2. Prompt Reporting of Product Complaints to Sponsor
Product complaints will be reported to the sponsor within 24 hours after the investigator becomes 
aware of the complaint.
The Product Complaint Form will be sent to the sponsor by email. If email is unavailable, then
fax should be utilized.
8.3.6.3.
Follow-up of Product Complaints
Follow-up applies to all participants, including those who discontinue study intervention.
The investigator is responsible for ensuring that follow-up includes any supplemental 
investigations as indicated to elucidate the nature and/or causality of the product complaint.
New or updated information will be recorded on the originally completed form with all changes 
signed and dated by the investigator and submitted to the sponsor.

8.4.
Treatment of Overdose
For this study, any dose of lasmiditan greater than 100 mg within a 24-hour time period will be 
considered an overdose.
There is no specific antidote for lasmiditan. 
In the event of an overdose, the investigator/treating physician should:
1. Contact the Lilly CP immediately.
2. Closely monitor the participant for any AE/SAE and laboratory abnormalities until study 
intervention can no longer be detected systemically (at least 2 days).
3. Document the quantity of the excess dose as well as the duration of the overdose in the 
eCRF.
Decisions regarding dose interruptions will be made by the investigator in consultation with the 
Lilly CP based on the clinical evaluation of the participant.
8.5.
Pharmacokinetics
Venous blood samples of approximately 2 mL will be collected for measurement of plasma
concentrations of lasmiditan and M8, as specified in the SoA (Section 1.3).
A maximum of 3 samples may be collected at additional time points during the study if 
warranted and agreed upon between the investigator and the sponsor.
Instructions for the collection and handling of biological samples will be provided by the 
sponsor. The actual date and time (24-hour clock time) of each sample will be recorded.
8.5.1.
Bioanalysis
Samples will be analyzed at a laboratory approved by the sponsor and stored at a facility 
designated by the sponsor.
Concentrations of lasmiditan and M8 will be assayed using a validated liquid chromatography 
with tandem mass spectrometry method.
Bioanalytical samples collected to measure study intervention concentrations will be retained for 
a maximum of 1 year following last participant visit for the study.
8.6.
Pharmacodynamics
Pharmacodynamic parameters are not evaluated in this study.

Product Acceptability and Palatability Assessments
The participant will be asked to provide responses to questions designed to assess the 
acceptability and palatability of the OD tablet when administered with and without water. The 
questionnaire will assess the participant’s experience relating to the taste, smell, mouthfeel, 
aftertaste, and the approximate disintegration time of the OD tablet in the oral cavity.
The questionnaire will be completed by the participant immediately after administration of the 
OD tablet both with and without water.

Statistical Considerations
9.1.
Statistical Hypotheses
Bioequivalence of the OD tablet without water versus the current IR tablet will be established if 
the 90% confidence interval (CI) of the ratio of geometric least square means for area under the 
concentration versus time curve (AUC) from time zero to infinity (AUC[(0-∞]), AUC from time 
zero to time t, where t is the last time point with a measurable concentration (AUC[0-tlast]), and 
maximum observed drug concentration (Cmax) is within the testing boundaries of 0.8 and 1.25.
9.2.
Sample Size Determination
A total of 36 participants are required complete the study to establish equivalence between the 
OD tablet formulation without water and the current IR tablet, based on the PK parameters 
measured.
Given the 6×3 design this would mean at least 6 participants would be randomly assigned to each 
of the 6 dosing sequences. The calculated total number of participants assumes 90% power for 
the two one-sided test (TOST) for equivalence with a significance level of 5%, analogous to a 
90% CI. Further, this is based on:

a nominally assigned true mean ratio of 1.05

a coefficient of variation for Cmax of 24.1%

ratio testing boundaries of 0.8 and 1.25.
Assuming that 25% of participants will drop out or fail to provide full study data, approximately 
48 participants should be enrolled to ensure that 36 participants, 6 per treatment sequence, will 
complete the study.
9.3.
Populations for Analyses
The following populations are defined:

Statistical Analyses
Statistical analysis of this study will be the responsibility of the sponsor or its designee.
Any change to the data analysis methods described in the protocol will require an amendment 
only if it changes a principal feature of the protocol. Any other change to the data analysis 
methods described in the protocol, and the justification for making the change, will be described 
in the statistical analysis plan (SAP) and the clinical study report. Additional exploratory 
analyses of the data will be conducted as deemed appropriate.
The SAP will be finalized prior to the first participant visit and it will include a more technical 
and detailed description of the statistical analyses described in this section. This section is a 
summary of the planned statistical analyses of the most important endpoints including primary 
and key secondary endpoints.
9.4.1. General Considerations
Data listings will be provided for all data that are databased. Data listings will be provided for all 
participants up to the point of withdrawal, with any participants excluded from the relevant 
population highlighted.
Summary statistics and statistical analysis will only be presented for data where detailed in the 
SAP. Summary statistics and statistical analyses will generally only be performed for 
participants included in the relevant analysis population. For the calculation of summary 
statistics and statistical analysis, unrounded data will be used.
9.4.2.
Pharmacokinetic Analyses
9.4.2.1.
Pharmacokinetic Parameter Estimation
Pharmacokinetic parameter estimates for lasmiditan and M8, based on plasma concentrations,
will be calculated by standard noncompartmental methods of analysis and summarized using 
descriptive statistics.
The primary PK parameters for analysis will be Cmax, AUC(0-∞), and AUC from time zero to 
time t, where t is the last time point with a measurable concentration (AUC[0-tlast]) of
lasmiditan.  
Other noncompartmental parameters, such as half-life, apparent clearance, and apparent volume 
of distribution may be reported.
9.4.2.2.
Pharmacokinetic Statistical Inference
Log-transformed AUC(0-∞), AUC(0-tlast), and Cmax of lasmiditan will be evaluated in a linear 
mixed-effects model with fixed effects for period, sequence, and treatment and a random effect 
for participant within sequence.
All valid PK data will be included, whether or not the participants completed all 3 periods.
Estimates of geometric least square mean ratios together with the corresponding 90% CIs will be 
derived for the comparisons of AUC(0-∞), AUC(0-tlast), and Cmax as follows:

Primary endpoint: lasmiditan OD tablet without water (test) versus lasmiditan IR tablet

CONFIDENTIAL
Protocol H8H-MC-LAIA
37

Secondary endpoint: lasmiditan OD tablet with water (test) versus lasmiditan IR tablet.
The 2 lasmiditan formulations will be considered bioequivalent if the 90% CIs of the ratio of 
geometric least square means falls completely within 0.80 to 1.25.
Values of tmax will be analyzed non-parametrically using the Wilcoxon signed rank test.
Estimates of the median difference between test and reference formulations based on the 
observed medians, 90% CIs, and the p-value from the Wilcoxon test will be calculated.
Additional PK analyses may be conducted if deemed appropriate.
9.4.3.
Safety Analyses
9.4.3.1.
Clinical Evaluation of Safety
All study intervention 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 study intervention 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 study intervention-related SAEs will be reported.
9.4.3.2.
Statistical Evaluation of Safety
Safety parameters that will be assessed include safety laboratory parameters and vital signs. The 
parameters will be listed and summarized using standard descriptive statistics. Additional 
analysis will be performed if warranted upon review of the data.

Collection of Pregnancy Information
Male participants with partners who become pregnant

The investigator will attempt to collect pregnancy information on any male participant’s 
female partner who becomes pregnant while the male participant is in this study. This 
applies only to male participants who receive lasmiditan.

After obtaining the necessary signed informed consent from the pregnant female partner 
directly, the investigator will record pregnancy information on the appropriate form and 
submit it to the sponsor within 24 hours of learning of the partner’s pregnancy. The 
female partner will also be followed to determine the outcome of the pregnancy. 
Information on the status of the mother and child will be forwarded to the sponsor. 
Generally, the follow-up will be no longer than 6 to 8 weeks following the estimated 
delivery date. Any termination of the pregnancy will be reported including fetal status 
(presence or absence of anomalies) and indication for the procedure. 
Female Participants who become pregnant

The investigator will collect pregnancy information on any female participant who 
becomes pregnant while participating in this study. The initial information will be 
recorded on the appropriate form and submitted to the sponsor within 24 hours of 
learning of a participant's pregnancy. 

The participant will be followed to determine the outcome of the pregnancy. The 
investigator will collect follow-up information on the participant and the neonate and the 
information will be forwarded to the sponsor. Generally, follow-up will not be required 
for longer than 6 to 8 weeks beyond the estimated delivery date. Any termination of 
pregnancy will be reported, including fetal status (presence or absence of anomalies) or 
indication for the procedure.

While pregnancy itself is not considered to be an AE or SAE, any pregnancy 
complication or elective termination of a pregnancy for medical reasons will be reported 
as an AE or SAE. 

A spontaneous abortion (occurring at <20 weeks gestational age) or still birth (occurring 
at ≥20 weeks gestational age) is always considered to be an SAE and will be reported as 
such. 

Any post-study pregnancy-related SAE considered reasonably related to the study 
intervention by the investigator will be reported to the sponsor as described in 
Section 8.3.4. While the investigator is not obligated to actively seek this information in 
former study participants, he or she may learn of an SAE through spontaneous reporting.

Any female participant who becomes pregnant while participating in the study will 
discontinue study intervention. If the participant is discontinued from the study 
intervention, follow the standard discontinuation process and continue directly to the 
follow-up phase. The follow-up on the pregnancy outcome should continue independent 
of intervention or study discontinuation.

Appendix 5: Genetics
Use/Analysis of DNA
Genetic variation may impact a participant’s response to study intervention, susceptibility to, and 
severity and progression of disease. Variable response to study intervention may be due to 
genetic determinants that impact drug absorption, distribution, metabolism, and excretion; 
mechanism of action of the drug; disease etiology; and/or molecular subtype of the disease being 
treated. Therefore, where local regulations and IRB/IEC allow, a blood sample will be collected 
for DNA analysis from consenting participants.
DNA samples will be used for research related to lasmiditan or migraine and related diseases. 
They may also be used to develop tests/assays including diagnostic tests related to lasmiditan
and/or interventions of this drug class and migraine. Genetic research may consist of the analysis 
of one or more candidate genes or the analysis of genetic markers throughout the genome or 
analysis of the entire genome (as appropriate).
The samples may be analyzed as part of a multi-study assessment of genetic factors involved in 
the response to lasmiditan or study interventions of this class to understand study disease or 
related conditions.
The results of genetic analyses may be reported in the clinical study report or in a separate study 
summary.
The sponsor will store the DNA samples in a secure storage space with adequate measures to 
protect confidentiality.
The samples will be retained while research on lasmiditan continues but no longer than 15 years 
or other period as per local requirements.
