If the PVT assessment schedule (10:00 h, 12:00 h, 14:00 h 
and 16:00 h) is too burdensome for the subject, it may be 
individually adapted to at least 3 assessments, with a time 
window of not less than 1 h between two PVT assessments.  
This change was implemented to relieve burden for those 
subjects who are not able to attend long-lasting trial visits. Its 
impact on the analysis of the PVT procedure should be 
limited as variables are analysed as a mean of the session 
performed at a given visit and not by timepoint.

Inclusion criteria no. 3 and 4 have been modified to increase 
the maximum age of subjects from 75 years to 80 years and 
the upper BMI limit from 30 kg/m2 to 35 kg/m2. 
The rationale for this change was the high pre-screening 
failure rate due to age and BMI restrictions. This change is 
considered acceptable given the exhaustive safety screening, 
including cognitive function (exclusion criterion no. 5) and 
mobility (inclusion criterion no. 2), and the exclusion of 
patients with cardiovascular risk factors (exclusion criterion 
no. 3) as well as the low dose of flecainide used in this trial.

Name of active ingredients: Modafinil, flecainide. 
Trial title: 
Randomised, double-blind, placebo-controlled, complete 3-way cross-over phase IIa trial to 
investigate safety and efficacy of two THN102 doses in subjects with excessive daytime sleepiness 
associated with Parkinson’s disease. 
Protocol number: THN102-202 
EudraCT number: 2017-004475-31 
Coordinating investigator:  
 
Investigators / trial sites: An estimated 28 sites in Europe and the USA. 
Planned duration of the trial: 
First subject first visit: Q2/2018 
Last subject last visit: Q4/2018 
Phase: IIa (proof-of-concept) 
Objectives: 
Primary objective: 
• 
To assess the safety profile of THN102 (modafinil/flecainide combination) at two doses 
(200 mg/18 mg and 200 mg/2 mg) versus placebo in subjects with excessive daytime sleepiness 
associated with Parkinson’s disease (PD). 
Secondary objectives: 
1. To quantify the efficacy of THN102 versus placebo in improving sleepiness. 
2. To quantify the efficacy of THN102 versus placebo in improving  
a. attention, vigilance 
b. cognition 
3. To determine the dose response profile of THN102 versus placebo on efficacy parameters. 
4. To determine the plasma levels of modafinil and flecainide at steady state. 
Methods / trial design: 
This is a prospective, double-blind, randomised, controlled trial using a complete 3-way cross-over 
design. Subjects will attend seven on-site visits and five phone call visits.  
The seven trial periods are depicted below:

10. Absence of residual somnolence, i.e. ESS < 11 at the end of each treatment period 
11. Psychomotor Vigilance Test (PVT) variables change from baseline at the end of each treatment 
period 
12. MoCA score change from baseline at the end of each treatment period 
13. Actimetry change (inactivity) from baseline at the end of each treatment period 
14. Number and duration of diurnal involuntary sleep attacks (subject diaries) change from baseline 
at the end of each treatment period 
15. Episodes of somnolence (subject diaries) change from baseline at the end of each treatment period 
 
Sample size justification  
For the purpose of sample size planning ESS is considered to be the key efficacy endpoint. Solid 
information on the expected difference between placebo and THN102 dose and the associated 
intrasubject variance are not available. Using results reported in Adler et al. as a rough orientation an 
effect size of 0.40 may constitute a conservative estimation for the comparison of the high THN102 
dose with placebo. A sample size of 54 subjects will have a power of 82% to detect this effect size 
based on a paired t-test with a 0.05 two-sided significance level. To account for drop outs 60 subjects 
will be randomised. 
 
Analysis populations 
• 
The Safety Set (SS) includes all subjects who have received IMP at least once. 
• 
The Full Analysis Set (FAS) includes all randomised subjects with an evaluable ESS score at the 
end of at least one treatment period. The efficacy analyses will be conducted on the FAS. 
• 
The Per Protocol (PP) set includes all subjects who have completed the trial without major protocol 
deviation. Major and minor violations will be defined in the SAP. The main secondary endpoints 
(ESS, PVT and cognition) will be analysed with the PP set to demonstrate robustness of the 
primary analysis.  
• 
The pharmacokinetic (PK) analysis set will include all subjects who have received treatment as 
per protocol (even if the trial was not completed) and who present no major protocol deviations 
with an impact on PK. 
 
Efficacy analysis 
Continuous efficacy endpoints – the change from baseline at each key visit (end of treatment period I, 
II, and III) in ESS, PVT and MoCA - will be analysed using a mixed linear regression model. The 
model will include the treatment, period, treatment by period interaction, sequence, and baseline scores 
as fixed effects, and the subject nested within sequence as a random effect.  
 
Categorical efficacy endpoints – absence of residual somnolence and ESS responder status at each key 
visit – will be analysed using a mixed effects logistic regression model, with the treatment, period, 
treatment by period interaction, sequence, and baseline scores as fixed effects, and the subject nested 
within sequence as a random effect. 
 
Treatment least square means and mean differences will be reported with their standard errors and 
95% confidence intervals. The significance of the differences between Treatment A (THN102 
Placebo), Treatment B (THN102 200/2) and Treatment C (THN102 200/18) will be assessed with a 
contrast t-test at the two-sided 5% level.

Supportive analysis 
The same analysis will be repeated on the PP set, to assess robustness of the analysis of the variables 
from ESS and PVT and possibly on other efficacy results. Subgroup analyses may be performed to 
investigate the effect of the main demographics (age, gender) and disease characteristics (in terms of 
daily sleepiness extent, and cognitive impairment) on the efficacy outcomes. 
 
The presence of a significant treatment by period interaction term in the main model may indicate a 
residual treatment (carryover) effect. In case of a significant treatment by period interaction, period I 
results will be analysed separately, and further analyses will be performed to explore the carry-over 
effects. The methods for evaluation of carryover effects will be defined in the SAP. 
 
Safety analysis 
Safety data will be summarised using summary statistics and frequency tabulations, as appropriate. 
 
Pharmacokinetics 
• 
Plasma concentrations of modafinil and flecainide at visits VR, V1B, V1C, V2B, V2C and V3B, 
considering time after last IMP intake. 
• 
Concentration-time data per treatment and subject for modafinil and for flecainide. Plasma 
concentrations and time post IMP intake, to assess range of exposure at steady state for each 
treatment.

8. The subject diary will be used continuously (i.e. also during washout periods) to record get-up time, total time (hours) slept last night, wake-up periods during night sleep, 
time of drug intake and number of capsules taken (except screening phase diary issued at VS1), somnolence episodes, diurnal involuntary sleep attacks, voluntary naps, 
number of caffeinated drinks and going-to-bed time.  
9. Visits V1A and V1B should be scheduled so that 3 days of actigraphy data can be collected. (The same for VS2 and VR, V2A and V2B, as well as V3A and V3B.) 
Actigraphy will be assessed using an actigraphy wrist band. 
10. MoCA should be performed in the morning. 
11. In case of early discontinuation, the same procedures as required for V3B will be performed.  
12. One PK blood sample will be taken when the subject arrives on the site. The times of blood withdrawal must be recorded. 
13. Starting from Day 21, the visit day numbers are theoretical, as the washout period is flexible and can be extended to up to 14 days. The 2-week duration of the treatment 
period is fixed.

INTRODUCTION 
1.1. Background 
Parkinson’s disease (PD) is one of the most common neurodegenerative disorders with an estimated 
prevalence of about 1% in subjects over 60 years of age. Among the non-motor symptoms of PD, sleep 
disorders are prominent and have a considerable negative effect on the quality of life of the patients. 
Excessive daytime sleepiness (EDS) occurs in 20-50% of PD patients, it appears to be linked to disease 
severity and duration. Current hypotheses about the etiology of EDS include neurodegenerative dopamine 
denervation, effects of dopaminergic drugs and nocturnal sleep disruption. [1,2] Currently there is no drug 
treatment approved for EDS in PD. Modafinil has been used in three small trials [3,4,5] with positive 
results in two of the three trials and was well tolerated. Pitolisant, an H3 inverse agonist has been tested 
in large scale phase III trials, however, results are not published. Phase II trials in EDS in PD subjects are 
ongoing with JZP-110, a norepinephrine-dopamine reuptake inhibitor and BEN-2001 (bavisant), an H3 
antagonist (Source: ClinicalTrials.gov). 
Modafinil, a wake promoting agent with a unique profile different from amphetamine, produces enhanced 
vigilance and arousal, is generally well tolerated and has been approved in the US for the treatment of 
daytime sleepiness in narcolepsy, [6,7,8,9]obstructive sleep apnea, and shift work disorder. In Europe the 
indication is limited to EDS in narcolepsy. Modafinil also has shown activity in fatigue in cancer, in 
neurodegenerative disorders, etc.). [10] Besides, many common situations involve short or long sleep 
deprivation periods or wake-sleep rhythm modifications. Sleep loss alters attention and vigilance, and 
reduces operational performance. Modafinil works well in sleep-deprived subjects to support vigilance, 
cognitive performance, coping skills, and recovery sleep. [11,12,13,14,15] Positive impact on cognition, 
performance, and mood was seen in healthy subjects. [16,17] 
Context: Theranexus has investigated new potential drugs for treating narcolepsy and cataplexy among 
others. Theranexus has recently demonstrated that flecainide – a class Ic antiarrhythmic compound – can 
significantly modify at very low dose the basic pharmacological profile of modafinil by enhancing 
modafinil activity on wakefulness and cognition. The mode of action of this combination called THN102 
is under investigation, preliminary data have been published. [18] 
Non-clinical safety pharmacology: According to scientific advice from the French Medicines Agency 
(ANSM) a safety pharmacology study was conducted in alert dogs monitored by telemetry over 24 hours 
prior to initiation of phase I and phase II. Vital signs, body temperature, and motor activity were recorded 
as well as ECG to investigate impact on cardiac electrophysiology profile and potential for arrhythmias 
with incremental single doses of 50/3, 50/9 and 75/9 mg/kg modafinil/flecainide acetate. Concomitantly 
to the dose-dependent increase in heart rate and blood pressure linked to spontaneous motor activity and 
estimated to be elicited by modafinil pharmacological activity, the PR and the QT intervals were 
shortened. No significant effects on the QRS or the corrected QT (Fridericia’s and van de Water’s 
formulae) intervals were noted. No arrhythmia and no other morphology change were observed over the 
test periods in any dog in this model, which is considered as highly predictive for man.  
First phase I trial in healthy volunteers: The safety and tolerance of THN102 was recently investigated 
in a 3-way cross-over, randomised, double-blind trial in 9 healthy male volunteers comparing single oral 
doses of THN102 (400 mg modafinil/50 mg flecainide acetate) to 400 mg modafinil/placebo and to 
placebo/placebo (trial THN102-101). The 50 mg dose selected for flecainide in phase I is derived of 
electrophysiological activity when administered alone and more than twice the maximum dose planned 
(18 mg) in this trial. In the phase I trial (THN102-101) body temperature as well as supine blood pressure 
and heart rate were increased over time in subjects with THN102 and modafinil treatment vs. subjects on 
placebo. No orthostatic symptoms were seen for any treatment. Safety and tolerance profile for adverse 
events was good and similar for THN102 and modafinil. In the 24 h Holter analysis performed by a central 
ECG laboratory blinded to treatment, no impact on cardiac electrophysiology was seen on QRS and QTcF 
(Fredericia’s formula) and no indication of arrhythmia or of morphological changes were documented for

THN102 and modafinil versus placebo. A marginal PR shortening for both active treatments was seen in 
line with the clear positive chronotropic effect. Addition of flecainide had no impact on the 
pharmacokinetic profile of modafinil, and parameters measured were similar (including Cmax, tmax, t1/2, and 
AUC) to modafinil given alone, and flecainide had the anticipated mean terminal plasma t1/2 (12.2 h) and 
median tmax (3 h) but a lower Cmax, possibly due to lack of dose linearity when administering at low dose. 
Second phase I trial in sleep-deprived healthy volunteers: A phase Ib trial has been terminated in Q2 
2016, in 20 healthy male volunteers undergoing a 40-hour sleep deprivation protocol. This trial THN102-
102 included 20 healthy male subjects, in a double-blind, randomised, incomplete-block 3-period cross-
over design involving 5 treatments (n=12 per group): placebo, modafinil 100 mg, and combinations 
THN102 (modafinil 100 mg and 1, 3 or 9 mg flecainide as THN1, THN3 and THN9), as 3 oral doses over 
18 h. THN102-treated volunteers showed a statistically significant improvement in their vigilance levels 
(PVT with speed as primary endpoint) versus modafinil alone without showing a linear dose effect. 
Secondary endpoints assessing cognition (2-back, Go-NoGo, Wisconsin Sorting Card Task) were 
consistent with this effect. These results reinforce the interest in THN102 for the treatment of excessive 
daytime sleepiness, a debilitating symptom affecting a number of patients with CNS disorders such as 
narcolepsy and Parkinson’s disease. 
Ongoing phase IIa trial in narcoleptic subjects: A phase IIa trial (Trial THN102-201, double-blind, 
crossover design with 3 randomised periods with 300 mg modafinil + placebo, 300 mg modafinil + 3 mg 
flecainide and 300 mg modafinil + 27 mg flecainide per day) is ongoing since September 2016. 48 
narcoleptic subjects will be included in a prospective, 5-site, placebo-controlled trial using a complete 
3-way cross-over design after a 2-week stabilisation period with modafinil and followed by 1-week 
washout.  
Objectives of this phase IIa trial: The most appropriate flecainide dose in THN102 remains to be 
selected in subjects with Parkinson’s disease (PD) experiencing excessive daytime sleepiness (EDS). This 
trial aims at assessing safety of THN102, efficacy on EDS, vigilance and cognition as well as modafinil 
and flecainide plasma levels at steady state.  
It is assumed that THN102 treatment should improve the excessive daytime sleepiness (EDS), without 
changing the safety profile seen with modafinil in Parkinson’s disease subjects. 
1.2. Test Drugs 
Extensive information on modafinil and flecainide can be found in their respective SmPCs (Summary of 
Product Characteristics, see investigator brochure, IB [31] Section 7 and 8). A table summarising the key 
features for both compounds and covering mechanism of action, safety pharmacology, pharmacokinetic 
profile, metabolism, dosing and most prevalent adverse events is provided in Table 1. Both compounds 
have been on the market for more than 20 and 30 years, respectively. At least one million patients have 
received modafinil for narcolepsy and other medical conditions worldwide and several millions have been 
treated with flecainide acetate. 
A review of THN102 pharmacology profile and safety pharmacology is provided in the IB. A dedicated 
electrophysiology study was performed in conscious dogs under telemetry with THN102 and no change 
on QTcF and QRS was detected up to maximum combination given (75 mg/kg modafinil + 9 mg/kg 
flecainide acetate) and no occurrence of arrhythmias was observed. Blood pressure, body temperature, 
and activity especially at night were increased, presumably linked to the awakening effects of THN102.

An extensive list of adverse events is presented in each SmPC, albeit from patients on chronic treatment, 
frequently on concomitant therapy and at a much higher dose in case of flecainide. These documents will 
serve as a basis to identify Suspected Unexpected Serious Adverse Reactions (SUSAR) in this trial (also 
see Section 7.2.2).  
Very rare incidence of severe cutaneous skin reactions (such as Stevens-Johnson syndrome, DRESS 
syndrome or Toxic Epidermal Necrosis) may occur with modafinil. As reviewed in the SmPC the 
incidence in clinical trials was found to be 0.8% in children (13 withdrawn out of 1585 cases and also 
including serious cutaneous adverse events) and 0% in adults based on exposure of 4264 patients.

1.3. Rationale for Trial Design and Dose Selection 
1.3.1. Trial design 
This proof-of-concept, phase IIa trial with THN102 should collect a sufficient body of information to 
assess the safety and efficacy profile of THN102 versus placebo in Parkinson’s disease subjects suffering 
from excessive daytime sleepiness. The sample size required for a crossover design is approximately one 
third of the size required in a parallel trial. To use a cross-over option is thus a viable alternative design, 
with a sample size of about 60 subjects in this condition. In addition, a direct comparison between THN102 
doses can be performed in the same subject. The selected trial design for this pilot proof-of-concept 
phase IIa trial is consequently a randomised, placebo-controlled, 3-way cross-over trial design comparing 
two dose levels of THN102 to placebo and followed by a washout period of 1-2 weeks. It was perceived 
as essential to take advantage of the cross-over design for exploring two doses of THN102 and comparing 
their impact on safety, ESS and other efficacy endpoints. The treatment duration of 2 weeks per period 
appears sufficient to observe therapeutic activity as the steady state will be reached after about 3 days of 
drug intake. Each treatment period is followed by a one-week washout period, which can be extended up 
to two weeks. In addition to the key efficacy endpoint, ESS, other efficacy endpoints have been selected, 
such as cognitive assessments including PVT and MoCA before and after each treatment period.  
A difference of 25% in ESS is considered clinically relevant. [26] Therefore responder rates will be 
analysed, with responders being defined as subjects with at least 25% improvement from baseline.  
1.3.2. Dose selection 
Based on the reported trial data with modafinil in PD subjects, a single morning dose of 200 mg was 
chosen, as it showed efficacy on EDS [3,5]. (Subjects aged above 65 years will be started on 100 mg 
during the first three days.) Trials using a higher dose (up to 400 mg) failed to show increased efficacy. 
[4] The flecainide doses were chosen based on preclinical pharmacological and exposure data as well as 
results of the phase Ib trial including healthy subjects after total sleep deprivation (THN102-102). 
1.4. Risk/Benefit Ratio 
1.4.1. Evaluation of risk 
It is anticipated that the safety and tolerance profile of THN102 is similar to that of modafinil given alone 
in a PD-EDS population, with frequent occurrence of headache, gastric pain, palpitation, tachycardia, 
dizziness, insomnia, anxiety, confusion, and blurred vision (see Table 1).  
For the treatment of tachyarrhythmias, flecainide is given at daily doses between 100 and 300 mg. In the 
present trial flecainide will be administered for EDS at two very low doses (2 mg, 18 mg as a single daily 
dose). In previous clinical studies with THN102 flecainide reached a mean (±SD) maximal concentration 
of 44.9±9.6 ng/mL when 50 mg were given as a single dose (study THN102-101), and of 19.5 ng/mL after 
27 mg (3 doses of 9 mg over 20 hours). The Cmax data appeared linear between flecainide doses of 3, 9, 
and 27 mg: 2.2±0.8 ng/mL, 6.4±2.2 ng/mL, and 19.5±4.5 ng/mL respectively. Extrapolating from steady 
state Cmax of 100 mg of flecainide [25] (173±46 ng/mL), one would expect a steady state Cmax for 18 mg/d, 
the maximal flecainide dose used in this trial, of about 30 ng/mL. This exposure level is well below 
exposure levels where cardiovascular AEs are expected for flecainide. [27] Flecainide does not trigger 
any significant cardiovascular effects below 100 ng/mL or even 200 ng/mL in plasma. [28,29,30]  
Thus, no cardiac effect is expected at the very low flecainide concentrations associated with the prescribed 
doses used in this trial and flecainide is not expected to raise any safety and tolerance issue in combination 
with THN102. As a precautionary measure cardiovascular exclusion criterion 3 has been included.  
In the two phase I trials with THN102 the adverse events’ profile did not significantly differ between 
THN102 and modafinil. A small but significant increase in blood pressure and heart rate was noted with 
both THN102 (400 mg/50 mg) and modafinil (400 mg/0 mg) in trial THN102-101 with 24-hour Holter

monitoring. No impact on cardiac conduction (QT, QRS) and no arrhythmia were seen (for more details, 
see the IB [31]). The lists of typical adverse events reported for modafinil and for flecainide are also listed 
in the IB and mentioned in the information for the subject.  
Risk will be minimised by regular contact between subject and investigator and by close safety monitoring.  
1.4.2. Evaluation of benefit 
These subjects have documented excessive daytime sleepiness (EDS) and it is expected that THN102 at 
one or both doses may significantly improve excessive daytime sleepiness, decreasing episodes of 
sleepiness and sleep attacks and may even improve night sleep in quantity and quality.  
This is a proof-of-concept trial in approximately 60 PD subjects with EDS treated with THN102 at two 
doses (200 mg/18 mg, 200 mg/2 mg) compared to placebo under a 3-way, double-blind, cross-over trial 
design. The exposure is thus limited (2 weeks at each dose). This design might contribute to a better 
understanding of the mode of action of THN102 in the target population, to define the profile for dose 
response and time response and to assess recovery after washout. If successful, a phase IIb-III trial could 
be initiated in the future.   
In summary, the risk/benefit ratio for this proof-of-concept trial is considered as satisfactory.

4.4. Screening Failures and Withdrawals 
4.4.1. Screening failures 
Screening failures will be all subjects who have been enrolled in the trial (i.e. ICF signed), but discontinue 
the trial prior to randomisation (at visit VR) due to whatever reason (withdraw consent, do not fulfil 
criteria, by decision of investigator, etc.). 
All subjects pre-screened, but not enrolled (i.e. no ICF signed), and all subjects enrolled (i.e. ICF signed) 
will be recorded in respective log forms. 
4.4.2. Withdrawals 
Subjects will be informed that they have the right to withdraw from the trial at any time, without prejudice 
to their medical care, and without having to justify their reasons and decision. Additionally, the 
investigator may discontinue the treatment of a subject at any time if he/she considers this to be in the 
subject’s best interest or if lack of compliance with recommendations has been noted.  
The investigator will decide on trial continuation after consideration of all available clinical elements 
presumed to impact on the subject’s safety. 
Subjects may withdraw or may be withdrawn from the trial for the following reasons: 
• 
at their own request (withdrawal of consent) 
• 
if in the investigator’s opinion, for reasons of safety or ethics, continuation in the trial would be 
detrimental to the subject’s well-being 
• 
major protocol deviations 
• 
treatment incompliance 
• 
prohibited concomitant therapy  
• 
adverse event 
• 
pregnancy 
• 
if the subject answered “yes” to point 4 and/or 5 of the C-SSRS. In this case the subject must be sent 
for psychiatric consultation 
• 
elevation of liver enzymes ALT or AST ≥ 5 times the upper limit of normal, or ALT or AST ≥ 3 times 
the upper limit of normal together with increased (total or conjugated) bilirubin ≥ 2 times the upper 
limit of normal 
• 
ECG signs of left ventricular hypertrophy, showing abnormality of at least one of the three indices 
listed below, confirmed by a cardiologist: 
o Sokolow-Lyon voltage (sum of amplitude of the S wave in lead V1 and the R wave in lead V5 or 
V6 ≥ 3.5 mV), or 
o Cornell voltage (S wave in V3 + R wave in aVL > 2.8 mV in men or > 2.0 mV in women), or 
o Modified Cornell (R wave in aVL > 1.1 mV) 
In this case, the subject must be referred to a cardiologist for further examinations.

• 
at the specific request of the sponsor 
In all cases, the reason for withdrawal must be recorded in the eCRF and in the subject's medical records. 
The subject must be followed up to establish whether the reason was an adverse event, and, if so, this must 
be reported in accordance with the procedures in this protocol. 
As far as possible, all examinations scheduled for visit V3B must be performed on all subjects who receive 
IMP but do not complete the trial according to protocol (early discontinuation visit, EDV). The 
investigator must make every effort to contact subjects lost to follow-up.  
In addition, visit V3C must be performed within 7 ±1 days after EDV. 
Efforts will be made to try maintaining all subjects in the trial until completion. 
4.5. Subject Identification 
A 6-digit number will be used to identify the subjects. The first 3 digits of the number will correspond to 
the site number. For example: Subject 101-001 will be the number given to the first subject who signed 
an ICF at site 101. 
The reference to the full names will be made in the subject’s identification list which must be kept strictly 
confidential. Only site number, subject number and randomisation number (if applicable) should appear 
in the eCRF and questionnaires. Age will be provided in eCRF for demographics. In the eCRF the 
randomisation number will be associated to the subject number in order to allocate the randomised 
sequence of treatment period. 
Subjects will wear a subject card during the trial, stating that they participate in a clinical trial and 
providing a contact name and telephone number of the investigator in case of need or of an emergency.

5.1.3. Timing of IMP doses and administration 
IMP will be administered only to subjects included in this trial, following the procedures set out in the 
trial protocol.  
IMP (2 capsules modafinil or placebo plus 2 capsules flecainide or placebo; 4 capsules in total) will be 
administered in the morning. IMP will be swallowed before meal with 150 mL tap water at 8:00 h (± 1 h).  
For subjects aged above 65 years: 
On the first, second and third day of each treatment period, 1 modafinil and 1 flecainide capsule will be 
taken. From the fourth to the last day of each treatment period, the regimen will be as described above. 
The time of IMP intake will be recorded in the subject diary daily. 
Dose adjustments will not be permitted. 
In each treatment period, first IMP intake will take place on the day after IMP dispensation, i.e. on the day 
after visit VR, V1C or V2C, respectively.  
In each treatment period, last IMP intake will take place on the day of visit V1B, V2B or V3B, 
respectively. 
5.1.4. Labelling and Packaging  
 (for contact details, see Section 14.1) will be in charge for over-encapsulation, labelling, preparation 
of treatment period kits and trial supply management in accordance with the randomisation list. 18 
capsules will be packed into a vial (sufficient for 1 week, with 4 capsules as reserve). Modafinil and 
flecainide capsules will be packed in separate vials. 
The IMP vials, boxes and kits will be labelled individually according to allocation schedule, site, subject 
number, trial period and content. All labels will be in the respective language of the country and will be 
in accordance with local regulations. (Multi-language label booklets will be used.) Label terminology may 
vary according to local regulations, and country-specific remarks will be added as needed. Sample labels 
will be filed in the TMF.

5.1.5. Drug storage and distribution  
Clinical supplies will be stored at trial site for subjects recruited if a locked, dedicated cupboard with 
temperature control and logging is available. If not, the clinical supply should be stored at the hospital 
pharmacy. 
For each treatment period, the box contains two vials with 18 capsules of modafinil 100 mg or its placebo 
and two vials of 18 capsules of flecainide of the corresponding assigned dosage or its placebo. The boxes 
will be kept under lock until treatment dispensation to the subject. The subjects will be provided with 
sufficient IMP for the next treatment period as defined by the randomisation scheme. Dispensations will 
be done at the end of VR, V1C and V2C. 
Subjects must be instructed to return all the dispensed medication vials, boxes and packaging material at 
the visit scheduled at the end of each period (V1B, V2B, V3B) whatever the state (intact, empty or partially 
used vials). Treatment medications accountability and compliance should be done at V1B, V2B and V3B 
by the investigators or their designee. 
5.2. Randomisation and Blinding 
5.2.1. Randomisation 
Subjects will be randomised to receive all three treatments, according to one of the six possible sequences 
(see Table 3).  
The statistics department of the clinical CRO will prepare the randomisation list using SAS® in the version 
specified in the data management plan (DMP). Randomisation data will be kept strictly confidential, 
accessible only to authorised persons, until the time of unblinding. The randomisation scheme will be 
included in the clinical trial report for this protocol. 
The procedure will be as follows: 
• 
After a subject's preliminary eligibility is confirmed, the site will enter the subject into the eCRF 
system.  
• 
The eCRF system will send a notification to the randomisation coordinator at the clinical CRO. 
• 
The randomisation coordinator will allocate the subject to the randomisation code as follows: 
o He/she will assign each screened subject to the next available randomisation number from the 
randomisation list until the first screening failure of a subject with an assigned randomisation 
code is documented.  
o After such a screening failure has occurred, the randomisation coordinator will assign 
randomisation numbers to subjects by taking into account the number of subjects allocated to 
each sequence, to ensure the balance (manual randomisation). 
o At sites with an unused kit from a previous screening failure, any new eligible subject will be 
assigned the randomisation number corresponding to the unused kit (forced randomisation). 
• 
The randomisation coordinator will enter the randomisation code into the eCRF system and request 
the warehouse to send the treatment kit (labelled with the randomisation code) and the emergency 
unblinding envelope to the respective site.  
• 
The randomisation coordinator will document the status of all screened subjects and kits and will keep 
track of the balance between treatment sequences and unused kits available at the sites.  
• 
A subject will only be considered randomised after his/her eligibility has been confirmed at VR. 
5.2.2. Blinding 
Modafinil 100 mg capsules and modafinil placebo capsules will be identical in size, colour and 
appearance. The packaging and labelling will not allow for any distinction between them. 
Likewise, flecainide 1 mg capsules, flecainide 9 mg capsules and flecainide placebo capsules will be 
identical in size, colour and appearance. The packaging and labelling will not allow for any distinction 
between them.

Clinical Trial Protocol

Final 6.0, 27 February 2019 
Theranexus S. A. 
Confidential 
During the trial, the subject and all personnel involved with the conduct and the interpretation of the trial, 
including the investigators, site personnel, and the sponsor’s staff, will be blinded to the treatment 
assignment. The randomisation schedule will be filed securely by the clinical CRO, in a manner such that 
blinding is properly maintained throughout the trial. Treatment assignment will not be available until the 
completion of the trial and until after final data review (clinical data base lock), except in the case of 
emergency. 
Emergency unblinding will be done via sealed emergency code envelopes. Unblinding will not to be done 
unless an actual emergency occurs, and knowledge of the subject’s treatment assignment affects his/her 
medical treatment. If possible, before breaking the blind the investigator consults with the medical monitor 
to ascertain the necessity of breaking the code. A record will be made of the date, time and reason for 
breaking the blind. Subjects with SUSARs will be unblinded for regulatory reporting by the CRO 
pharmacovigilance representative. Other trial personnel and the investigators will receive blind 
information on the SUSAR until the trial has been unblinded. 
The principal investigator at each trial site and the pharmacovigilance representative will be provided with 
individual sealed emergency envelopes containing treatment assignment to be maintained in locked area 
and to be opened only in case of a medical emergency. The integrity of these sealed envelopes will be 
checked by the CRA at the end of the trial.  
The allocation schedule will be transmitted electronically to the CRO in charge of secondary packaging. 
A secrecy agreement will be signed by the PK analyst and no individual data will be distributed or 
discussed with any other party until the database has been frozen and the code has been released. The 
pharmacists at trial site are blinded to trial treatment.  
All other groups involved in trial support will only have access to treatment assignment after delivering 
data planned as per protocol and after data freezing. Electronic transfer of allocation schedule to 
investigators, sponsor, CRO's trial manager, and to other parties will be performed after freezing of the 
database. All documents for blinding and for signature of secrecy agreements will be filed in the TMF. 
The set of envelopes from principal investigators at each trial site and from pharmacovigilance will be 
recovered at trial completion, inspected for integrity and destroyed by the sponsor. The integrity 
statements will be stored in the TMF. 
5.3. Clinical Supplies Accountability 
The investigator or pharmacist will document IMP dispense and return on a drug accountability form. 
This will be verified by the CRA and documented on the same form. In addition, the investigator or 
pharmacist will maintain a site inventory. 
Drug dispensation logs will be maintained throughout the trial at each visit and for each subject by site 
staff. Comparison between capsules count and eCRF as well as comparison between capsules count and 
subject diaries will be performed to obtain information on compliance. The originals of these log forms, 
along with the filled drug accountability form will be filed in the ISF and copies will be collected for the 
TMF. 
After reconciliation at the end of the trial, all unused IMP will be returned to the warehouse. 
5.4. Treatment Compliance 
The trial medication will be administered at home by the subject and to ensure adequate drug compliance 
is consequently a key issue. Instructions will be provided to the subject on respecting time schedule trying 
to maintain same time schedule throughout the trial and a 24-hour interval (± 1 hour) between daily doses.

5.5. Prior and Concomitant medication 
Efficacious medication for Parkinson's disease should not be discontinued for the sole purpose of 
the subject's enrolment into this clinical trial but must be maintained at stable dosage levels 
(exclusion criterion no. 11f). 
The following concomitant medication is prohibited during the trial and within 6 weeks before VS1: 
1. Neuroleptics, anxiolytics, anticonvulsants. Benzodiazepines and benzodiazepine-like drugs are only 
authorised if used regularly at stable indicated doses with an evening intake as sleep promoting agents. 
2. Psychostimulants (except caffeine if no abuse and stable consumption) such as, but not limited to, 
modafinil, methylphenidate, amphetamine. 
3. Antidepressants except if maintained at stable dose for at least 6 weeks prior to VS1 and anticipated 
to remain stable during the trial in subjects with mild or moderate unipolar depression, providing the 
treatment is well tolerated and devoid of orthostatic hypotension and QT prolongation as documented 
at screening. 
4. Antiemetic medications (except domperidone), myo-relaxing drugs and opioids. 
5. Antiarrhythmic drugs class I (see Section 14.3). 
6. Dopaminergic medications, unless they have been used at stable doses for at least 4 weeks before 
screening and it is anticipated that the doses will not be changed throughout the trial. 
7. 
Centrally acting anti-obesity drugs. 
8. 
TNF-alpha inhibitors. 
Co-prescription of CYP2D6 inhibitors, CYP3A4,5 or CYP2C19 substrates has to be closely monitored. 
The doses of such co-prescribed drugs have to be decreased as appropriate. The decision will be made by 
the investigator after consulting with the medical monitor, if necessary. A list of the most important 
CYP2D6 inhibitors and of CYP3A4,5 and CYP2C19 substrates is provided in Section 14.4. 
 
Sexually active women of child-bearing potential must be established on a contraceptive programme (see 
inclusion criterion no. 7). Since the effectiveness of steroidal contraceptives may be reduced when used 
with IMP, alternative or concomitant methods of contraception are recommended during the trial, and for 
two months after discontinuation of IMP. 
For more information, please refer to the Investigator's Brochure (Section 5.3, Drug-drug interactions; 
Sections 7 and 12.3 of Modafinil SmPC, and Section 8.1 of Flecainide SmPC). 
5.6. Lifestyle and Diet 
Subjects should be advised that driving ability, operation of machinery and work without a secure fit may 
be affected by adverse reactions such as dizziness and visual disturbances. 
There are no trial restrictions with respect to smoking. Moderate consumption of caffeine (tea, coffee, 
cola, energy drinks etc.) and alcoholic beverages (such as 200 mL of beer or 100 mL wine per day) will 
be permitted. Grapefruit consumption and quinine-containing drinks should be avoided. 
Additional information regarding contraindications, precautions and warnings concerning IMP are 
provided in the current version of the IB. [31] 
5.7. Further Treatment after the End of the Trial 
After the end of the trial, the subjects will be treated according to local standard practice.

• 
Adverse event collection 
 
6.2. Baseline Assessments 
6.2.1. Demography 
The investigator will record demographic data, including (but not limited to) age, gender, race, and will 
measure height (also used for BMI calculation). 
6.2.2. Medical history, concomitant diseases 
In an interview, medical history will be evaluated by the investigator in order to determine whether the 
subject fulfils the inclusion criteria and meets none of the exclusion criteria. Concomitant diseases that 
might be present at VS1 must be recorded in the eCRF.  
Medical conditions that are diagnosed at VS1 will only be documented as adverse events, if they are 
known to have started or are suspected to have started after the ICF has been signed. All other medical 
findings at the medical examination at VS1 will be documented as medical history. 
6.2.3. Prior and concomitant treatments and lifestyle 
Any treatment that was given in addition to IMP during the trial is regarded as a concomitant treatment 
and must be documented on the appropriate pages of the eCRF, specifying drug taken, dose, route, 
start/stop date and reason for use. 
Therapies administered within 3 months before VS1 will also be documented in the eCRF. 
All concomitant drugs must be known to and approved by the investigator and should be maintained stable 
during the trial unless mandatory to increase or decrease the dose to ensure a better efficacy or a better 
safety for the subjects. All changes in therapy or in doses must be documented in the eCRF. The subject 
should mention all other drugs, including over the counter medication such as acetylsalicylic acid. 
Consumption of alcohol will be recorded in the eCRF at VS1, consumption of grapefruit products and 
quinine-containing drinks not. 
6.2.4. Modified Hoehn & Yahr stage 
The investigator will assess the subject's Hoehn & Yahr stage as follows: 
0 
No signs of disease. 
1 
Unilateral disease. 
1.5 
Unilateral plus axial involvement.

2 
Bilateral disease, without impairment of balance. 
2.5 
Mild bilateral disease, with recovery on pull test. 
3 
Mild to moderate bilateral disease; some postural instability; physically independent. 
4 
Severe disability; still able to walk or stand unassisted. 
5 
Wheelchair bound or bedridden unless aided. 
6.2.5. Calculation of glomerular filtration rate 
For the verification of exclusion criterion no. 9, the glomerular filtration rate will be calculated based on 
2009 CKD-EPI creatinine equation [32] as follows: 
GFR [mL/min/1.73 m2] =  
141 x min(SCr/κ, 1)α x max(SCr /κ, 1)-1.209 x 0.993Age x 1.018 [if female] x 1.159 [if Black] 
SCr = standardised serum creatinine [mg/dL] 
κ = 0.7 (females) or 0.9 (males) 
α = -0.329 (females) or -0.411 (males) 
min(SCr/κ, 1) = indicates the minimum of SCr/κ or 1 
max(SCr/κ, 1) = indicates the maximum of SCr/κ or 1 
age [years] 
6.3. Safety Assessments 
6.3.1. Adverse events 
For adverse events see Section 7. 
6.3.2. Safety laboratory and pregnancy tests 
Serology, haematology, blood coagulation and biochemistry analyses will be performed by a central 
laboratory. Urinalysis (dipstick) and urine pregnancy test (women of childbearing potential only) will be 
performed by trial site staff on-site. For the list of parameters, see Section 14.2. 
For safety laboratory tests, approximately 10 mL of blood will be collected at each blood withdrawal.  
Laboratory values outside the normal ranges have to be assessed by the investigators if clinically 
significant abnormal or not clinically significant abnormal. 
Each change to clinically significant abnormal laboratory value during the trial has to be documented as 
an AE in the eCRF unless the measurement is identified to be caused by a laboratory error and unless the 
underlying disease causing the change to laboratory abnormality is already documented. Clinically 
significant abnormal laboratory values at VS1 not related to any already documented underlying disease 
have to be documented as medical history. 
6.3.3. Vital signs and weight 
Vital signs (systolic and diastolic blood pressure as well as heart rate) will be measured twice: after 5 
minutes supine rest and after 2 minutes in standing position (one set of supine and standing vital signs).

At VR, V1C and V2C three sets of supine and standing vital signs will be measured with 15-20 min 
intervals between the sets.  
Weight will be measured in street clothes without shoes. 
6.3.4. Electrocardiogram (ECG) 
The sponsor will provide the investigator with the ECG device that shall be used in this trial. Twelve-lead 
ECG will be recorded after 10 minutes in supine position. ECG reading will be performed centrally by the 
provider specified in Section 14.1 and will include  
• 
ECG measured parameters as intervals (PR, QRS, QT)  
• 
Pattern of change for PR, QRS and QT versus ECG from baseline  
• 
Derived ECG parameters (QTcF, heart rate)  
ECG will be recorded at VS1, VR, V1B, V1C, V2B, V2C and V3B. 
6.3.5. Columbia-Suicide Severity Rating Scale (C-SSRS) 
The C-SSRS is a tool that was developed to facilitate a prospective, systematic monitoring for the 
emergence of suicidal tendencies in clinical studies. It is used to compare the occurrence, severity, and 
frequency of suicide-related thoughts and behaviours during treatment in a clinical trial.  
The C-SSRS Screening version will be used at VS1 to obtain baseline data. The recall period will be set 
to 12 months / 1 year. Exclusion criterion no.6 will be met if the subject answers “yes” to items 4 and/or 
5 of the C-SSRS only referring to the last month before VS1. 
The C-SSRS Since Last Visit version will be used to capture changes in the subject’s status at VR, V1B, 
V1C, V2B, V2C and V3B. 
Subjects who answer “yes” to point 4 and/or 5 of the C-SSRS will be withdrawn from the trial and will 
be sent for psychiatric consultation. 
6.3.6. Movement Disorder Society-Sponsored Version of Unified 
Parkinson's Disease Rating Scale (MDS-UPDRS) 
The MDS-UPDRS is a comprehensive assessment of both motor and non-motor symptoms associated 
with Parkinson's disease. [33] It has four parts: 
• 
Part I (non-motor experiences of daily living, 13 items), further divided into: 
o Part IA focuses on complex behaviors and is completed by the investigator, based on interview 
with the subject 
o Part IB focuses on non-motor experiences of daily living and is completed by the subject 
• 
Part II (motor experiences of daily living, 13 items), completed by the subject 
• 
Part III (motor examination, 33 items), completed by the investigator 
• 
Part IV (motor complications, 6 items) completed by the investigator, based on interview with the 
subject.  
The MDS-UPDRS rates 65 items on a 5-point scale: normal (0), slight (1), mild (2), moderate (3) and 
severe (4). 
The MDS-UPDRS will be completed at baseline and at the end of each treatment period, i.e. at visits: VR, 
V1B, V2B and V3B.

6.3.7. Questionnaire for Impulsive-Compulsive Disorders in Parkinson’s 
Disease – Rating Scale (QUIP-RS) 
The QUIP-RS is a validated tool designed to measure the severity of symptoms of impulse control 
disorders (ICDs) and related disorders. [34] The QUIP-RS consists of four primary questions, each applied 
to four ICDs (compulsive gambling, buying, eating and sexual behaviour) and three related disorders 
(medication use, punding and hobbyism). The QUIP-RS uses a 5-point Likert scale (score 0-4 for each 
question) to rate the severity of each symptom based on its weekly frequency. To be applicable in this 
trial, the standard 4-week recall period will be reduced to one week. 
The total ICD score ranges from 0 to 64, and the total QUIP-RS score for all ICDs and related disorders 
ranges from 0 to 112. 
The QUIP-RS will be provided in a local language. The investigator will complete the scales based on 
interview with the subject.  
The QUIP-RS will be completed at baseline and at the end of each treatment period (visits: VR, V1B, 
V2B and V3B). 
6.3.8. Physical examination 
Physical examination includes an examination of the organ systems head, neck, eyes, ear-nose-throat, 
heart, respiratory, gastrointestinal, hepatic, urogenital, musculoskeletal, vascular, lymphatic, 
dermatologic, central-nervous system (CNS) and psychiatric. 
6.4. Efficacy Assessments 
6.4.1. Epworth Sleepiness Scale (ESS) 
The subject will complete the Epworth Sleepiness Scale (ESS, 1-week recall period). The questionnaire 
will be provided in local language. Site staff will enter ESS data into the eCRF. 
6.4.2. Psychomotor Vigilance Test (PVT) 
The psychomotor vigilance test is an objective tool used to measure the subject's behavioural alertness. 
[35] It is a visual test which involves measuring  
• 
Mean response time (ms) 
• 
Number of lapses 
• 
Number of total errors 
The PVT requires no training, only a brief explanation of the procedure to the subject prior to the start of 
the test. It will be performed in the 'on' state. 
PVT will be performed at 10:00 h, 12:00 h, 14:00 h and 16:00 h (± 0:15 h each). If this PVT assessment 
schedule is too burdensome for the subject, it may be individually adapted to at least 3 assessments, with 
a time window of not less than 1 h between two PVT assessments. Once chosen, the timeframe of PVT 
assessments should remain constant during the trial for each subject. 
The sponsor will provide the investigator with a PVT-192 device to perform a 3-minutes PVT and a 
notebook computer to read out data. 
6.4.3. Montreal Cognitive Assessment (MoCA) 
The MoCA is a brief screening instrument to detect mild cognitive impairment. It is a paper-and-pencil 
tool that requires approximately 10 minutes and will be administered by the investigator. It will be 


THN102-202

performed in the 'on' state. The MoCA assesses multiple cognitive domains including attention, 
concentration, executive functions, memory, language, visuospatial skills, abstraction, calculation and 
orientation. One part of the paper questionnaire will be completed by the subject, another part will be 
completed by the investigator. Site staff will enter MoCA data into the eCRF. 
The MoCA questionnaire will be provided in local language. To decrease possible learning effects, the 
three (equivalent) versions 7.1, 7.2 and 7.3 will be used in alternation. 
MoCA should be performed in the morning. 
MoCA scores range between 0 and 30. A score of 26 or over is considered to be normal.  
6.4.4. Actigraphy assessment 
Actigraphy is a non-invasive method of monitoring a person's rest and activity cycles. The movements the 
actigraphy sensor undergoes are continually recorded.  
The sponsor will provide the investigator with actigraphy sensors for the trial subjects and a notebook 
computer to read out data. The actigraphy data will be transferred to 
 
), where they will be further processed and stored. 
Actigraphy assessments will be performed for 3 days prior to baseline and for 3 days at the end of each 
treatment period. At phone call visits VS2, V1A, V2A and V3A, trial staff will call the subjects and remind 
them to put on their actigraphy sensor bracelet and wear it until the next on-site visit. 
6.4.5. Subject diaries 
The paper-based subject diaries are intended for the daily documentation of 
• 
Get-up time  
• 
Total time (hours) slept last night 
• 
Wake-up periods during night sleep 
• 
Time of drug intake (except screening phase diary) 
• 
Number of capsules taken (except screening phase diary) 
• 
Somnolence episodes 
• 
Diurnal involuntary sleep attacks 
• 
Voluntary naps 
• 
Number of caffeinated drinks 
• 
Going-to-bed time 
The diaries will be translated in the local languages of the countries involved. Only the subject is allowed 
to make any entry in the diaries. In case of difficulties with writing, however, a caregiver may help. 
The subject will complete four paper diaries: One screening phase diary (started at VS1, without time of 
IMP intake and number of capsules taken) and treatment phase diaries (started at VR, V1C and V2C) for 
each treatment period. The subject has to bring the diaries for inspection by the investigator at all visits. 
The screening phase diary will be collected at VR, the treatment phase diaries will be collected at V1C, 
V2C and V3B. 
Thus, the diaries will be completed continuously from VS1 to V3B, i.e. also during the washout periods 
after treatment periods I and II.

6.5. Pharmacokinetics (PK) 
For PK laboratory tests, approximately 4.5 mL of blood will be collected at each blood withdrawal. The 
sample will be taken when the subject arrives on the site. The times of blood withdrawal must be recorded. 
Modafinil and flecainide concentrations in plasma will be measured by a central laboratory (for contact 
details, see Section 14.1) using a validated LC-MS/MS method.

ADVERSE EVENT, PREGNANCY AND EMERGENCY 
7.1. Adverse Event (AE)  
7.1.1. Definition of an adverse event 
An adverse event is any untoward medical occurrence in a clinical trial subject administered a medicinal 
product and which does not necessarily have a causal relationship with this treatment. 
AEs can be symptoms, signs, or clinically relevant laboratory abnormalities occurring during the course 
of the trial. 
All other medical conditions, which are present at VS1, should not be considered as AEs unless a 
worsening in severity or frequency has occurred during the trial. These medical conditions should be 
adequately documented on the appropriate page of the eCRF. 
When reporting abnormal laboratory results on the AE pages of the eCRF, a clinical diagnosis should be 
recorded rather than the abnormal value itself if this is available (e.g. “anaemia” rather than “decreased 
red blood cell count” or “haemoglobin = 10.5 g/dL”). 
In case of surgical or diagnostic procedures, the condition/illness leading to such a procedure is considered 
as the AE rather than the procedure itself. 
7.1.2. Severity assessment 
The investigator must systematically assess the severity of adverse events according to the following 
definitions: 
• 
Mild: a type of adverse event that is usually transient and may require only minimal treatment or 
therapeutic intervention. The event does not generally interfere with usual activities of daily living. 
• 
Moderate: a type of adverse event that is usually alleviated with additional specific therapeutic 
intervention. The event interferes with usual activities of daily living, causing discomfort but poses 
no significant or permanent risk of harm to the research participant. 
• 
Severe: a type of adverse event that requires intensive therapeutic intervention. The event interrupts 
usual activities of daily living, or significantly affects clinical status. The event possesses a significant 
risk of harm to the research participant and hospitalisation may be required. 
Changes in the severity of an AE should be documented as a new AE. Adverse events characterised as 
intermittent requires documentation of the onset and duration of each episode. 
7.1.3. Relationship assessment 
The investigator must systematically assess the relationship of adverse events to the IMP using the 
following definitions: 
• 
Unrelated: A clinical event with no evidence of any causal relationship. 
• 
Unlikely: A clinical event, including laboratory test abnormality, with a temporal relationship to drug 
administration which makes a causal relationship improbable, and in which other drugs, chemicals or 
underlying disease provide plausible explanations. 
• 
Possible: A clinical event, including laboratory test abnormality, with a reasonable time sequence to 
administration of the drug, but which could also be explained by concurrent disease or other drugs or 
chemicals. Information on drug withdrawal may be lacking or unclear. 
• 
Probable: A clinical event, including laboratory test abnormality, with a reasonable time sequence to 
administration of the drug, unlikely to be attributed to concurrent disease or other drugs or chemicals, 
and which follows a clinically reasonable response on withdrawal (dechallenge). Rechallenge 
information is not required to fulfil this definition. 


THN102-202 
Clinical Trial Protocol 
Page 46 of 74 
Final 6.0, 27 February 2019 
Theranexus S. A. 
Confidential 
• 
Definite: A clinical event, including laboratory test abnormality, occurring in a plausible time 
relationship to drug administration, and which cannot be explained by concurrent disease or other 
drugs or chemicals. The response to withdrawal of the drug (dechallenge) should be clinically 
plausible. The event must be definitive pharmacologically or phenomenologically, using a satisfactory 
rechallenge procedure if necessary. 
The relationship to IMP can be modified during the trial or AE assessment. For example, although an AE 
may rate only as “possibly” related to IMP soon after discovery, it can be flagged as requiring more 
information and later be upgraded to “probably”. Changes in the assessment of relationship to IMP should 
be clearly documented. 
Mapping to the two categories “related” and “unrelated”: The categories “unrelated” and “unlikely” will 
be mapped to “unrelated”, the categories “possible”, “probable” and “definite” will be mapped to 
“related”. 
7.1.4. Procedures for reporting of adverse events 
Assessing of adverse events 
Data on AEs will be obtained at scheduled or unscheduled trial visits, based on information spontaneously 
provided by the subject and/or through questioning of the subject. AE data may also be obtained from 
subject’s diary cards, but information thus collected must be reviewed and assessed medically before it is 
transcribed to the eCRF. 
If a subject is seen by a physician not involved in the trial because of an adverse event, the investigator 
should make every effort to contact the treating physician in a timely manner in order to obtain all 
information necessary to appropriate reporting of the event. 
Recording of adverse events 
Complete description of all adverse events must be available in the source documents. 
All AEs including local and systemic reactions should be captured on the appropriate pages of the eCRF.  
Information to be recorded, based on above assessment criteria, includes event description, its duration 
(time of onset and time of resolution), its severity, whether it is considered serious (and if so the criterion 
satisfied), its relationship to IMP, any action taken (concerning the IMP or other) and its outcome.  
Any AE that is still ongoing after final visit will be left as ongoing in the eCRF. However, the investigator 
will continue to follow up ongoing SAEs and record information in the source documents and on the 
Follow-Up SAE Form, until resolution or no further improvement can be expected. 
AEs must be recorded on the eCRF according to the following guidelines: 
• 
Whenever possible, recognised medical terms should be used to describe an AE rather than 
colloquialism (e.g. “influenza” rather than “flu”) and abbreviations should be avoided. 
• 
The description of an AE should use a specific clinical diagnosis, if this is available, rather than a 
list of component signs or symptoms (e.g. “congestive heart failure” rather than “dyspnea, rales 
and cyanosis”). 
• 
Signs and symptoms that are not linked to an identified disease or syndrome, or for which an 
overall diagnosis is not available, should be reported separately, as individual AEs. 
• 
Provisional diagnosis (e.g. “suspected myocardial infarction”) is acceptable but should be 
followed up to a definite diagnosis if finally available. 
Reporting of adverse events 
Complete and accurate data on all AEs experienced, for the duration of the reporting period, will be 
reported on an ongoing basis in the AE pages of the eCRF. 


THN102-202 
Clinical Trial Protocol 
Page 47 of 74 
Final 6.0, 27 February 2019 
Theranexus S. A. 
Confidential 
The period of observation for the collection of AEs extends from the time when the subject gives informed 
consent until the date of final visit.  
Serious adverse events occurring after a subject has taken the last dose of IMP will be collected until the 
date of final visit, regardless of the investigator's opinion of causation. Thereafter, SAEs are not required 
to be reported unless the investigator feels the events were related to either IMP administration or to a 
protocol procedure. 
All AEs with onset or worsening after first intake of IMP until 7 days after last intake of IMP are defined 
as treatment emergent. 
If a subject is documented as lost-to follow-up, ongoing/unknown outcome AEs will not be followed up. 
For screening failure subjects, new AEs and updates must be recorded in the source and trial documents 
until the date the subject is determined to be a screening failure. Beyond this date, only SAEs will be 
followed up by CRO’s pharmacovigilance representative.  
7.2. Serious Adverse Event (SAE) 
7.2.1. Definition of a serious adverse event  
A serious adverse event (SAE) is defined as an AE which at any dose meets one of the following 
conditions: 
• 
Death during the period of protocol defined surveillance, i.e. the AE causes or contributes to the 
death. In case of fatality, the cause of death is considered as the AE, and the death is its outcome. 
• 
Life threatening event (defined as a subject at immediate risk of death at the time of the event), 
i.e. the AE places the subject at immediate risk of death (the definition does not apply to an AE 
that hypothetically might cause death if it was more severe). 
• 
An event requiring inpatient hospitalisation or prolongation of existing hospitalisation during the 
period of protocol defined surveillance, i.e. the AE requires at inpatient hospitalisation or prolongs 
a hospitalisation beyond the expected length of stay.  
• 
Hospital admissions are not to be considered as SAE according to this criterion in the following 
purposes: surgery planned before trial entry, social reasons, normal disease management 
(including treatment adjustment), if the protocol procedures or the standard management of the 
disease under study requires planned hospitalisations.  
• 
Results in a persistent or significant disability/incapacity, i.e. the AE resulted in a substantial 
disruption of the subject’s ability to conduct normal activities. 
• 
Any other important medical condition, i.e. AE that may not immediately result in death, be life 
threatening, or require hospitalisation, but is clearly of major clinical significance. Based upon 
appropriate medical judgment, the event may jeopardise the subject or may require medical or 
surgical intervention to prevent one of the serious outcomes listed above. Examples of such 
medical events include allergic bronchospasm requiring intensive treatment in an emergency 
room or at home, blood dyscrasia or convulsions that do not result in inpatient hospitalisation, or 
the development of drug dependency or drug abuse.  
Any serious adverse event requires an expedited reporting to the pharmacovigilance delegate regardless 
of its relationship to the IMP. 
7.2.2. Definitions of Suspected Unexpected Serious Adverse Reactions 
(SUSAR) 
Suspected unexpected serious adverse reaction (SUSAR) is an adverse reaction, the nature or severity of 
which is not consistent with the applicable product information (e.g. investigator’s brochure for an 
unauthorised investigational product or summary of product characteristics for an authorised product). 


THN102-202 
Clinical Trial Protocol

Final 6.0, 27 February 2019 
Theranexus S. A. 
Confidential 
7.2.3. Procedures for reporting of SAEs and SUSARs 
All serious adverse events must be recorded on the SAE report form, followed through resolution by the 
investigator. 
The investigator must complete the SAE report form and notify the CRO’s pharmacovigilance delegate, 
be it a new SAE or new information on a previously reported SAE (i.e. so-called SAE follow-up), within 
the following timelines: 
• 
The investigator must report all SAEs to the CRO’s pharmacovigilance delegate within 24 hours 
of identifying the SAE. 
• 
Other supporting documentation of the event may be requested by CRO’s pharmacovigilance 
delegate and should be provided as soon as possible. 
• 
All reportable SAEs will be followed until satisfactory resolution or until the investigator deems 
the event to be chronic or the subject to be stable.  
The SAE report form must be sent directly to the CRO’s pharmacovigilance delegate by electronic 
mail or facsimile as specified below: 
 
 
 
 
  
 
 
For any new SAE, the following minimum information is required as initial notification: 
• 
Identification of the investigator, 
• 
Subject identification details (subject number) 
• 
IMP details (name, dose(s), route and date(s) of administration, indication) 
• 
Diagnosis of the event (or an outcome) with the description (or a brief description of signs/ 
symptoms/clinical course if the diagnosis is not available) and the date of onset 
• 
Reason(s) for considering the event as serious 
• 
Relationship of the event with the IMP or with the trial procedure (i.e. the causality according to 
the investigator). 
Information about SAEs and important medical conditions with any relevant ongoing/unknown outcomes 
will be followed-up until resolution, even if eCRFs and database will no longer be updated. SAEs 
occurring after a subject has taken the last dose of trial drug will be collected until final study visit, 
regardless of the investigator's opinion of causation. Thereafter, serious adverse events are not required to 
be reported unless the investigator feels the events were related to either IMP administration or a protocol 
procedure.  
7.2.4. Procedures for regulatory reporting of serious adverse events 
Following notification by the investigator, sponsor or designee will report events that are both serious and 
unexpected (i.e. using the current version of the THN102 IB at the time of SAE reporting as reference) 
and that are associated with IMP to the competent authorities (CAs) in expedited reporting. Unblinding 
will be performed as described in Section 5.2.2 by opening the individual sealed envelope for the involved 
subject. 
Moreover, any other new information that might influence the benefit-risk assessment of the IMP or that 
would be sufficient to consider changes in IMP administration or in the overall conduct of the clinical trial 
necessitate an expedited reporting to the CAs as well. 


THN102-202 
Clinical Trial Protocol 
Page 49 of 74 
Final 6.0, 27 February 2019 
Theranexus S. A. 
Confidential 
CAs should be notified of any expedited reporting within the required timelines as specified in ICH-E2A: 
fatal and life-threatening events within 7 calendar days (by phone/fax/writing/electronic communication) 
after first knowledge by CRO’s pharmacovigilance delegate who will issue a complete report within 8 
additional calendar days, with copy to investigator, CRA, CRO's trial manager, and sponsor. All other 
serious adverse events and SUSARs must be filed in writing within 15 calendar days after first knowledge 
by CRO’s pharmacovigilance delegate.   
All serious adverse events will be reported to the CAs in the development safety update report (DSUR) 
annually, if appropriate. 
In accordance with the ICH GCP guidelines, the responsible person for pharmacovigilance on behalf of 
the sponsor Theranexus will inform the investigators of findings that could affect adversely the safety of 
the subjects, impact the conduct of the trial, or alter the IEC/IRB’s approval/favourable opinion to continue 
the trial. 
In particular, sponsor or designee will inform the investigators of SUSARs and serious adverse events that 
are considered to be related to the administered IMP. The investigators will keep copies of these safety 
reports in the investigator site file (ISF). National regulations with regards to safety reports notifications 
to investigators will be taken into account.  
Unless clearly defined otherwise by national or site-specific regulations and duly documented, the clinical 
CRO will promptly notify the concerned IEC/IRB of any safety reports provided by the 
pharmacovigilance delegate and provide copies of all related correspondence to the CRA and the CRO's 
trial manager.  
7.3. Pregnancy 
Women of childbearing potential (defined as not surgically sterile or less than 2 years postmenopausal), 
must use a highly effective method of contraception, and must continue for the duration of the trial (and 
for 2 months after participation in the trial). Highly effective methods of contraception include: hormonal 
contraception associated with inhibition of ovulation (combined estrogen/progestogen: oral, intravaginal, 
transdermal; progestogen-only: oral, implanted, and injected) in conjunction with a barrier method 
(preferably male condom). Highly effective methods further include intrauterine device (IUD), 
intrauterine hormone-releasing system (IUS), bilateral tubal occlusion, vasectomised partner (provided 
that the partner is the sole sexual partner of the subject and the vasectomised partner has received medical 
assessment of the surgical success) and sexual abstinence, i.e. when this is in line with the preferred and 
usual lifestyle of the subject.  
Women of child-bearing potential will undergo sensitive urinary pregnancy tests (hCG, human chorionic 
gonadotropin). 
Pregnancy discovered during the clinical trial must lead immediately to exclusion (if at screening) or 
withdrawal of the subject. 
If the subject has already received IMP, the pregnancy will be documented on a pregnancy report form. 
The case must be reported within 24 hours of knowledge to the CRO’s pharmacovigilance delegate or the 
CRA. The subjects will be asked to report also pregnancies within 3 months after (regular or premature) 
termination of the trial to the investigator. 
The investigator must follow up on pregnancies discovered after IMP administration until the end of 
pregnancy to document the outcome on the pregnancy outcome report form. 
7.4. Emergency 
In case of emergency situations, the investigator should contact first his/her assigned CRA, and in case of 
no answer the CRO's trial manager and/or the sponsor's trial manager. 
Emergency identification of IMP:

Since this trial is blinded for treatment periods I, II, and III, two sets of individual sealed randomisation 
envelopes with treatment code (individual sealed envelopes with scratch labels for disclosure of treatment) 
will be prepared. One set will be delivered to the principal investigator at each site and one full set to the 
CRO's medical monitor prior to trial start.  
In case of urgent need during the trial, the envelope pertaining to the involved subject may be opened by 
the investigator in case of an SAE for which knowledge of exact treatment may be useful for medical 
decision or for treatment. Such an event must be documented by the investigator by signing and dating 
the envelope (including precise time) and indicating the reason for breaking the code on the appropriate 
form. Efforts must be made to reach the medical monitor before undertaking this step. All envelopes must 
be retrieved at trial completion from trial site by the CRA and inspected for integrity. All envelopes from 
investigator, intact or opened, will be filed in the TMF.

• 
The Safety Set (SS) includes all subjects who have received IMP at least once. 
• 
The Full Analysis Set (FAS) includes all randomised subjects with an evaluable ESS score at the end 
of at least one treatment period. The efficacy analyses will be conducted on the FAS. 
• 
The Per Protocol (PP) set includes all subjects who have completed the trial without major protocol 
deviation. Major and minor violations will be defined in the SAP. The main secondary endpoints 
(ESS, PVT and cognition) will be analysed with the PP set to demonstrate robustness of the primary

• 
The PK analysis set will include all subjects who have received treatment as per protocol (even if the 
trial was not completed) and who present no major protocol deviations with an impact on PK. 
 
8.3. Statistical Methods 
Details of the planned analyses will be described in the SAP. Some important features are listed below: 
• For all analyses, the results will be pooled and presented by treatment and over time. Graphical 
representations will be done for individual subject data and for treatment means ± SD over time. 
• Efficacy data will be analysed according to the treatment as randomised. Safety and pharmacokinetic 
data will be summarised according to the actual treatment received. 
• Continuous (quantitative) variables will be tabulated using standard descriptive statistics (number of 
observations, mean, standard deviation, median, minimum and maximum values, for efficacy and some 
safety parameters, with geometric mean and geometric CV) if appropriate. Continuous variables may 
be categorised into grouped intervals for analysis; in which case frequencies and percentages will also 
be presented.  
• Categorical (qualitative) variables will be tabulated using frequencies and percentages. 
 
8.3.1. Efficacy 
Continuous efficacy endpoints – the change from baseline at each key visit (end of treatment period I, II, 
and III) in ESS, PVT and MoCA - will be analysed using a mixed linear regression model. The model will 
include the treatment, period, treatment by period interaction, sequence, and baseline scores as fixed 
effects, and the subject nested within sequence as a random effect.  
Categorical efficacy endpoints – absence of residual somnolence and ESS responder status at each key 
visit – will be analysed using a mixed effects logistic regression model, with the treatment, period, 
treatment by period interaction, sequence, and baseline scores as fixed effects, and the subject nested 
within sequence as a random effect. 
Treatment least square means and mean differences will be reported with their standard errors and 95% 
confidence intervals. The significance of the differences between Treatment A (THN102 Placebo), 
Treatment B (THN102 200/2) and Treatment C (THN102 200/18) will be assessed with a contrast t-test 
at the two-sided 5% level. 
Handling of missing values/censoring/discontinuations: Subjects who misused their planned treatments 
or doses or have missing outcome measurements will not be excluded from the primary analysis in the 
FAS. Under the assumption that outcomes are missing at random, the mixed-model can propagate 
uncertainty due to missing data into estimates of treatment efficacy and other quantities of interest. Hence, 
missing data will not be imputed or replaced prior to the analysis. 
Supportive analysis: The same analysis will be repeated on the PP set, to assess robustness of the analysis 
of the variables from ESS and PVT and possibly on other efficacy results. Subgroup analyses may be 
performed to investigate the effect of the main demographics (age, gender) and disease characteristics (in 
term of daily sleepiness extent, and cognitive impairment) on the efficacy outcomes. 
The presence of a significant treatment by period interaction term in the main model may indicate a 
residual treatment (carryover) effect. In case of a significant treatment by period interaction, period I 
results will be analysed separately, and further analyses will be performed to explore the carry-over 
effects. The methods for evaluation of carryover effects will be defined in the SAP. 
8.3.2. Safety 
Safety parameters will be analysed as follows:

Theranexus S. A. 
Confidential 
Vital signs: All vital signs data will be listed by treatment, subject, and visit/time and will be flagged vs. 
predefined clinical normal range. The mean value of vital sign parameter assessments during a visit will 
be summarized. Summary statistics will be provided by treatment and visit/time. Shift tables will be 
provided for vital sign abnormality change from baseline to endpoint within each treatment period. 
ECG parameters: All ECG parameters data will be listed by treatment, subject, and visit/time and 
abnormalities will be flagged vs. predefined clinical normal range. Summary statistics will be provided 
by treatment and visit/time.  
A shift table will be prepared to document QT change and distribution vs. baseline. 
C-SSRS: C-SSRS score data will be listed by treatment, subject, and visit/time. Summary statistics will 
be provided by treatment and visit/time.  
QUIP-RS: QUIP-RS score data will be listed by treatment, subject and visit/time. Summary statistics will 
be provided by treatment and visit/time. 
MDS-UPDRS: MDS-UPDRS score data will be listed by treatment, subject and visit/time. Summary 
statistics for each part of the MDS-UPDRS as well as the total score will be provided by treatment and 
visit/time. 
Clinical laboratory evaluations: All laboratory data will be listed by treatment, subject, and visit/time 
and abnormalities will be flagged vs. common normal range if considered by investigator as clinically 
relevant. Summary statistics will be provided by treatment and visit/time. Shift tables will be provided for 
clinical laboratory variables’ change from baseline to endpoint. 
Adverse events: All information obtained on adverse events will be displayed by treatment and subject 
after coding with pertinent MedDRA version. All adverse events and related adverse events will be 
presented. The number and percentage of subjects with adverse events will be tabulated by body system 
and preferred term with a breakdown by treatment. An adverse event starting in one period and continuing 
into the next period is counted only in the onset period. A subject with multiple adverse events within a 
body system is only counted once towards the total of this body system. 
Concomitant medications / Significant non-drug therapies: All concomitant therapies will be coded 
by WHO version and listed by treatment group and subject. 
8.3.3. Pharmacokinetics 
As soon as they are available but only after database has been frozen, analytical determinations will be 
sent by e-mail (Microsoft Excel® file) by the bioanalytical center of 
 to the sponsor's 
PK expert (with copy to Theranexus, CRO's trial manager). All the transmission of data must be done in 
blinded condition up to the reception of the certificate of database lock by CRO. 
Subsequently, plasma concentrations will be processed for PK data generation.  
For the calculation of the PK parameters and characteristics the following rules are usually applied:  
• 
All the plasma concentrations validated by the bioanalytical laboratory and provided to the 
pharmacokineticist will be used for the PK analysis. 
• 
The actual blood sampling time points related to the preceding administration will be used. 
• 
At time points in the lag-time between time zero and the first concentration equal or above LLOQ 
(lower limit of quantification), concentrations below LLOQ will be set to zero. Concentrations 
below LLOQ between two concentrations equal or above LLOQ will be set to half the LLOQ. 
Trailing concentrations below LLOQ will not be used in calculations.  


THN102-202 
Clinical Trial Protocol

Final 6.0, 27 February 2019 
Theranexus S. A. 
Confidential 
• 
For plasma concentration above the upper limit of quantification and reported as ALQ (above limit 
of quantification) in the final plasma concentration tables, ALQ will be replaced by the first 
measurement for the PK analysis. 
• 
Not reported concentration will be excluded from the PK analysis. 
Plasma concentrations reached at steady state will be presented for modafinil and for flecainide for each 
visit, considering time after last IMP intake. 
Concentration-time data will be listed per treatment and subject for modafinil and for flecainide. Plasma 
concentrations and time post IMP intake will also be plotted to assess range of exposure at steady state for 
each treatment and to assess reliability of prediction made by extrapolation from phase I studies for 
flecainide. 
Further details of the pharmacokinetic analyses will be defined in the SAP. 
8.4. Interim Analysis 
No formal interim analysis is planned. 
8.5. Sample Size Justification 
For the purpose of sample size planning ESS is considered to be the key efficacy endpoint. Solid 
information on the expected difference between placebo and THN102 dose and the associated intrasubject 
variance are not available. Using results reported in Adler et al. [5] as a rough orientation an effect size of 
0.40 may constitute a conservative estimation for the comparison of the high THN102 dose with placebo. 
A sample size of 54 subjects will have a power of 82% to detect this effect size based on a paired t-test 
with a 0.05 two-sided significance level. To account for drop outs 60 subjects will be randomised.

9. 
ETHICAL AND LEGAL ASPECTS  
9.1. Good Clinical Practice 
This trial will be conducted in compliance with the protocol, good clinical practice (GCP) and the 
applicable regulatory requirements. 
The procedures set out in this trial protocol, pertaining to the conduct, evaluation, and documentation of 
this trial, are designed to ensure that investigators, sponsor, CRO’s pharmacovigilance delegate, CRAs 
and CRO's trial manager all abide by the principles of GCP, ICH guidelines and all applicable international 
and local regulations as well as the ethical principles laid down in the current revision of the Declaration 
of Helsinki.  
9.2. Delegation of Investigator Responsibilities 
The investigator should ensure that all persons assisting with the trial are adequately informed about all 
relevant trial procedures and well-trained on the protocol, any amendments to the protocol, the trial 
treatments, and their trial-related duties and functions. 
Each investigator should maintain a list of sub-investigators and other appropriately qualified persons to 
whom he/she has delegated significant trial-related duties. 
9.3. Subject Information and Informed Consent 
Before being admitted to the clinical trial, the subject must consent to participate after the nature, scope, 
and possible consequences of the clinical trial have been explained in a form understandable to him/her. 
An informed consent document that includes both information about the trial and the consent form will 
be prepared and given to the subject. This document will contain all elements required by law and 
sponsor’s requirements. The document must be in a language understandable to the subject and must 
specify who informed the subject.  
After reading the informed consent document, the subject must give consent in writing. The subject's 
consent must be confirmed at the time of consent by the personally dated signature of the subject. It is not 
considered appropriate to allow a subject who is legally incompetent to enter this trial under the coverage 
of the subject's legally authorised representative. 
A copy of the signed informed consent document must be given to the subject.  
The investigator will not undertake any measures specifically required for the clinical trial purposes until 
valid consent has been obtained. 
9.4. Confidentiality 
Only the subject number will be recorded in the eCRF and transfer documents (no initials), and if the 
subject name appears on any other document (e.g. ECG, laboratory report, pathologist report), it must be 
obliterated before a copy of the document is supplied to other parties. The subjects will be told that 
principal investigator and his/her staff, CRO’s staff, IEC/IRB, regulatory authorities, and representatives 
of the sponsor may inspect their medical records to verify the information collected, and that all personal 
information made available for inspection will be handled in strictest confidence and in accordance with 
all applicable data protection laws. 
Biological samples collected during the trial will be used for assays specifically described in the protocol. 
The samples will be destroyed after approval of the clinical trial report (CTR) upon written request. 
The investigator will maintain a personal subject identification list (subject numbers with the 
corresponding subject names) to enable records to be identified.

9.5. Protocol Amendments 
No signee of this protocol (coordinating investigator, principal investigator, sponsor), nor the CRO's trial 
manager will alter this trial protocol without obtaining the written agreement of the other parties. Once 
the trial has started, amendments should be made only in exceptional cases. The changes then become part 
of the trial protocol and request a protocol amendment. 
9.6. Approval of the Trial Protocol and Amendments 
Before the start of the trial, the clinical CRO will submit to the IEC/IRBs and the competent authorities 
(CAs) all relevant trial documents. The trial will not start until authorisation by CAs and by IEC/IRBs 
have been received in writing and until the administrative requirements and workload (grid costs) have 
been discussed with the hospital administration and the agreements have been signed. 
Trial medication can only be supplied to the investigator after documentation on all ethical and legal 
requirements for starting the trial has been received by the trial CRA. This documentation must also 
include a list of the members of the IEC/IRB and their occupation and qualifications. The opinion given 
by the IEC/IRB should specify the trial title, trial code, trial site, amendment number if appropriate and 
any other documents reviewed. It must mention the date on which the decision was made and must be 
officially signed by a committee member. 
Before the first subject is enrolled in the trial, all ethical and legal requirements must be met. 
The IEC/IRB and, if applicable, the authorities must be informed of all subsequent protocol amendments, 
in accordance with legal requirements. Amendments must be evaluated to determine whether formal 
approval must be sought and whether the informed consent document should also be revised. 
The investigator must keep a record of all communication with the IEC/IRB. This also applies to any 
communication between the investigator and the authorities. 
9.7. Ongoing Information for the Independent Ethics Committee / 
Institutional Review Board 
The responsible IEC/IRB will be informed by the clinical CRO of all subsequent protocol amendments 
and of SUSARs occurring during the trial that are likely to affect the safety of the subjects or the conduct 
of the trial. 
Protocol amendments referring to logistical or administrative changes (non substantial) may be 
implemented with notification of the IEC/IRB and competent authority only. 
9.8. Premature Closure of the Trial 
The sponsor (Theranexus) has the right to close this trial under special considerations or events involving 
safety considerations or issues with recruitment. As far as possible, this should occur after mutual 
consultation and attempt of remedy with all trial sites. The IEC/IRB and the CA must be promptly 
informed. 
Should the trial be closed prematurely, all IMP must be returned to the warehouse, as if the trial had been 
completed. All other trial material (actigraphy sensors, PVT device, notebook, ECG device etc.) must also 
be returned. 
The sponsor reserves the right to close the trial at a site for one of the following (or other) reasons: 
• 
Non-compliance with GCP and/or regulatory requirements 
• 
Centre cannot recruit an adequate number of subjects 
• 
False documentation in the eCRF due to carelessness or deliberation 


THN102-202 
Clinical Trial Protocol 
Page 57 of 74 
Final 6.0, 27 February 2019 
Theranexus S. A. 
Confidential 
• 
Inadequate co-operation with the sponsor or its representatives 
If the trial is prematurely terminated at a trial site, all investigators at this trial site have to inform their 
subjects and take care of appropriate follow-up and further treatment of the subjects. IEC/IRBs and the 
CA will be informed according to the applicable laws and regulations. 
9.9. Regular Termination of the Trial 
The end of this trial is defined as the date of the last visit of the last subject undergoing this trial.  
Within 90 days of the end of the clinical trial, the clinical CRO will notify IECs/IRBs and regulatory 
authorities about the regular termination of the trial as required according to national laws and regulations.  
If the trial has to be terminated early, this period shall be reduced to 15 days and the reasons clearly 
explained. 
9.10. Archiving and Record Retention 
The following records must be retained by the principal investigator in the investigator site file (ISF) for 
a minimum of 15 years after the completion or termination of the trial: 
• 
Signed informed consent documents for all subjects 
• 
Subject identification list, subject non-eligibility log and subject enrolment log 
• 
Record of all communications between the investigator and the IEC/IRB 
• 
Composition of the IEC/IRB  
• 
Record of all relevant communications between the investigator and sponsor’s representatives 
• 
List of sub-investigators and other appropriately qualified persons to whom the investigator has 
delegated significant trial-related duties, together with their roles and their signatures 
• 
Copies of case report forms and of documentation of corrections for all subjects 
• 
Drug accountability records 
• 
Record of any body fluids or tissue samples retained 
• 
All other source documents (patient records, hospital records, laboratory records, worksheets etc.) 
• 
All other documents as listed in Section 8 of the ICH consolidated guideline on GCP (Essential 
Documents for the Conduct of a Clinical Trial) 
However, because of international regulatory requirements, Theranexus may request retention for a longer 
period of time. The investigator must therefore obtain approval in writing from Theranexus or from the 
CRO's trial manager prior to destruction of any records. 
Normally, these records will be held in the investigator's archives. If the investigator is unable to meet this 
obligation, he must ask Theranexus for permission to make alternative arrangements. Details of these 
arrangements should be documented. 
9.11. Liability and Insurance 
In accordance with GCP and ICH guidelines, the clinical CRO (authorised by the sponsor) has subscribed 
to an insurance policy covering, in its terms and provisions, its legal liability for injuries caused to 
participating persons and arising out of this research performed strictly in accordance with the scientific 
protocol as well as with applicable law and professional standards. 
The insurance certificate will be submitted with the documents to the IEC/IRB.

10. TRIAL MONITORING AND AUDITING 
10.1. Trial Monitoring 
The CRO's CRAs will review the eCRFs and source documents, supported on occasions by the CRO's 
trial manager or the sponsor. By frequent communications (letter, e-mail, telephone and fax), the CRO's 
trial manager and the CRAs will ensure: 
• 
that the investigation is conducted according to protocol design and requirements, 
• 
that potential deviations are discussed and queries solved, always working according to regulatory 
guidelines. 
The sponsor, the CRO's trial manager and the CRAs may at any time demand information on the progress 
of the trial by phone or in writing, or may visit the trial centre in order to monitor trial procedures and to 
review the original trial documents and subject's data. 
After trial completion, used and unused IMP will be verified, reconciled with eCRF, diaries and log forms. 
Intact and used clinical supplies will be returned to the CRO involved with clinical packaging after 
reconciliation of clinical supplies by CRA and after written instruction.  
CRO’s standard operating procedures (SOPs) are available for all activities relevant to trial monitoring 
and to process at trial sites.  
10.2. Source Data Verification and On-Site Audits 
The local IEC/IRB, and/or a clinical quality assurance group delegated by the sponsor (Theranexus), or 
the CA acting on its own or at specific request of EMA or FDA may request access to all source 
documents, eCRF, and other trial documentation for on-site audit or inspection as may be indicated. Direct 
access to these documents must be guaranteed by the investigators, who must provide support at all times 
for these activities.

11. DATA HANDLING AND RECORD KEEPING 
11.1. Electronic CRF and Database 
An electronic case report form (eCRF) will be used. The clinical CRO will provide the system. 
Questionnaires filled by subject will be provided on paper. Trial staff will transfer the results into the 
eCRF.  
Electronic device for PVT tests and actigraphy will be provided by the CRO to each site. The 
questionnaires will be considered as source documents and filed in the ISF.  
The investigator or delegate must maintain adequate and precise source documents (safety laboratory test 
results, ECG, physical examination etc.), also including the diaries and the questionnaires filled by the 
subject. The trial data will be entered into the eCRF by dedicated site personnel.  
Medical history and AE data will be coded by system organ class and Lowest Level Term, using the 
current version of the MedDRA dictionary. Concomitant medication data will be coded by Drug Name, 
taking Preferred Name and ATC into account, using the World Health Organization Drug Dictionary 
Enhanced (WHO DDE), current version. 
Further details will be provided in the DMP and in the pertinent SAP. 
11.2. Documentation of Trial Findings 
Details on monitoring process by the CRA will be included in the monitoring plan. 
The plasma concentrations data will be transmitted by
 to data management for 
inclusion into the trial database. The format and the details however will be provided in the analytical 
protocol to be prepared by 
 and in the SAP. 
The investigator, or designated representative, should complete the source documents (including 
worksheet pages, if applicable) immediately after information is collected, when a trial subject is seen for 
an examination, treatment, or any other trial procedure. Any outstanding entries must be completed 
immediately after the final examination. An explanation should be provided for all missing data. 
A source data location list will be prepared and updated as required.  
The completed eCRF must be reviewed and signed by the principal investigator named in the trial protocol 
prior to transmission to the sponsor.  
11.3. Use of Trial Findings 
All information concerning the drug product, such as clinical indications for the drug, its formula, methods 
of manufacture and formulations and other scientific data relating to it, that have been provided to 
investigators and are unpublished, will be considered as confidential and must remain the sole property of 
Theranexus. The investigator agrees to use the information only for the purposes of carrying out this trial 
and for no other purpose unless prior written permission from Theranexus is obtained. 
By signing the trial protocol, the principal investigator agrees that the results of the trial may be used for 
the purposes of national and international registration, publication, and information for medical and 
pharmaceutical professionals. The principal investigator also agrees that one or more designated staff 
members will be responsible for maintaining the investigator site file (ISF). The trial master file (TMF) 
will be maintained by the clinical CRO and transferred to sponsor after trial completion. 
The sponsor or designee will be responsible for preparing the CTR. The coordinating investigator will be 
required to sign a statement that he has read the CTR and that he confirms that, to the best of his 
knowledge, it accurately describes the conduct and results of the trial.

Due to non-substantial changes in the data collected and no changes in the statistical methodology 
described by the protocol, this SAP is written assuming the latest protocol version (Final 6.0 or 
Final 8.0 France). Differences between the protocol versions will be listed in the relevant subsections 
of the SAP. 
The SAP includes detailed procedures for executing the statistical analysis of the primary and secondary 
variables and other data, and it is structured according to different data types. The SAP is finalised and 
signed-off prior to unblinding the trial. 
Actigraphy data collected over the course of the trial will be evaluated by a research team from 
 The corresponding AX3 Analysis Plan is included as an appendix (see Section 9). The 
resulting derived data will be transferred to 
 for efficacy analysis, which is described in Section 
5.6.7. 
All analysis data sets and statistical output will be produced by the statistics department at
 
using the SAS system version 9.4 for Windows (SAS 
Institute Inc., Cary, NC, USA) [1].

4. Vital signs: Systolic and diastolic blood pressure as well as heart rate will be measured twice: after 5 minutes of supine rest and after 2 minutes in standing position (one 
set). At VR, V1C and V2C three sets of supine and standing vital signs will be measured 15-20 min apart.  
5. Weight will be measured in street clothes without shoes. 
6. At VS1 the C-SSRS Screening version will be completed. At other visits, the C-SSRS Since Last Visit version will be completed. 
7. PVT will be done at 10:00 h, 12:00 h, 14:00 h and 16:00 h (± 0:15 h each). If this PVT assessment schedule is too burdensome for the subject, it may be individually 
adapted to at least 3 assessments, with a time window of not less than 1 h between two PVT assessments. Once chosen, the timeframe should remain constant during the 
trial for each subject. 
8. The subject diary will be used continuously (i.e. also during washout periods) to record get-up time, total time (hours) slept last night, wake-up periods during night sleep, 
time of drug intake and number of capsules taken (except screening phase diary issued at VS1), somnolence episodes, diurnal involuntary sleep attacks, voluntary naps, 
number of caffeinated drinks and going-to-bed time.  
9. Visits V1A and V1B should be scheduled so that 3 days of actigraphy data can be collected. (The same for VS2 and VR, V2A and V2B, as well as V3A and V3B.) 
Actigraphy will be assessed using an actigraphy wrist band. 
10. MoCA should be performed in the morning. 
11. In case of early discontinuation, the same procedures as required for V3B will be performed.  
12. One PK blood sample will be taken when the subject arrives on the site. The times of blood withdrawal must be recorded. 
13. Starting from Day 21, the visit day numbers are theoretical, as the washout period is flexible and can be extended to up to 14 days. The 2-week duration of the treatment 
period is fixed.

Overall Trial Design 
This is a prospective, double-blind, randomised, placebo-controlled trial using a complete 3-way 
cross-over design. Subjects will be assessed during  twelve visits (seven on site and five by phone 
call). The seven trial periods are depicted in Table 1.

* Washout periods can be extended to up to 2 weeks, if this is more convenient for the subject. 
 
The trial procedures by visit are presented in the flow chart in Section 1. 
At visit VR the subjects will be equally randomised (1:1:1:1:1:1) double-blind to a treatment sequence 
containing three periods (shown in Table 2).

The duration of each treatment period is 2 weeks, with a 1-week washout in between (to avoid carry-
over effects) and 1-week follow-up period after the last treatment period. Washout periods can be 
extended up to two weeks. THN102 will be administered orally once daily. 
2.4 
Randomisation 
The statistics department of the clinical CRO will prepare the randomisation list using SAS® in the 
version specified in the data management plan (DMP). Randomisation data will be kept strictly 
confidential, accessible only to authorised persons, until the time of unblinding. The randomisation 
scheme will be included in the clinical trial report for this protocol. 
The procedure will be as follows: 
• 
After a subject's preliminary eligibility is confirmed, the site will enter the subject into the eCRF 
system.  
• 
The eCRF system will send a notification to the randomisation coordinator at the clinical CRO. 
• 
The randomisation coordinator will allocate the subject to the randomisation code as follows: 
o He/she will assign each screened subject to the next available randomisation number from 
the randomisation list until the first screening failure of a subject with an assigned 
randomisation code is documented.  
o After such a screening failure has occurred, the randomisation coordinator will assign 
randomisation numbers to subjects by taking into account the number of subjects allocated 
to each sequence, to ensure the balance (manual randomisation). 
o At sites with an unused kit from a previous screening failure, any new eligible subject will 
be assigned the randomisation number corresponding to the unused kit (forced 
randomisation). 
• 
The randomisation coordinator will enter the randomisation code into the eCRF system and request 
the warehouse to send the treatment kit (labelled with the randomisation code) and the emergency 
unblinding envelope to the respective site.  
• 
The randomisation coordinator will document the status of all screened subjects and kits and will 
keep track of the balance between treatment sequences and unused kits available at the sites.  
• 
A subject will only be considered randomised after his/her eligibility has been confirmed at VR.

2.6 
Sample Size 
For sample size planning ESS was considered to be the key efficacy endpoint. Solid information on 
the expected difference between placebo and THN102 dose and the associated intrasubject variance 
were not available. Using results reported in Adler et al. [4] as a rough orientation an effect size of 
0.40 may constitute a conservative estimation for the comparison of the high THN102 dose with 
placebo. A sample size of 54 subjects will have a power of 82% to detect this effect size based on a 
paired t-test with a 0.05 two-sided significance level. To account for drop outs 60 subjects will be 
randomised. 
 
In this exploratory phase 2a study, no adjustment for multiple testing will be applied. 
2.7 
Blinding 
Modafinil 100 mg capsules and modafinil placebo capsules are identical in size, colour and 
appearance. The packaging and labelling will not allow for any distinction between them. 
Likewise, flecainide 1 mg capsules, flecainide 9 mg capsules and flecainide placebo capsules are 
identical in size, colour and appearance. The packaging and labelling will not allow for any distinction 
between them. 
During the trial, the subject and all personnel involved with the conduct and the interpretation of the 
trial, including the investigators, site personnel, and the sponsor’s staff, are blinded to the treatment 
assignment. The randomisation schedule is filed securely by the clinical CRO, in a manner such that 
blinding is properly maintained throughout the trial. Treatment assignment will not be available until 
the completion of the trial and until after final data review (clinical data base lock), except in the case 
of emergency. 
3. ANALYSIS SETS AND SUBGROUPS 
3.1 
Analysis sets 
The Enrolled Set (ES) includes all subjects who have signed the informed consent form. 
The Randomised Set (RS) includes all subjects randomised at visit VR.

Version 6 
The Full Analysis Set (FAS) includes all randomised subjects with an evaluable ESS score at the end 
of at least one treatment period. Evaluability of treatment periods is described in Section 5.6. The 
efficacy analyses will be conducted on the FAS. 
The Per Protocol (PP) set includes all subjects in the FAS who have at least one treatment period 
without a major protocol deviation. Major and minor violations are defined in Sections 5.1.2 and 5.6. 
The main secondary endpoints (ESS, PVT and cognition) will be analysed with the PP set to 
demonstrate robustness of the primary analysis. 
The PK analysis set will include all subjects who have received treatment as per protocol (even if the 
trial was not completed) and who present no major protocol deviations with an impact on PK. 
3.2 
Subgroups 
No subgroups are defined for the primary analysis of this study.

4. GENERAL DEFINITIONS AND NAMING CONVENTIONS   
To avoid ambiguity during the analysis, a number of definitions and conventions for data handling are 
described here. 
4.1 
General Methodology and Presentation of the Results 
The default summary statistics for quantitative (continuous) variables will be  
- 
the number of subjects (n),  
- 
mean,  
- 
standard deviation (SD),  
- 
median,  
- 
first quartile (Q1) and third quartile (Q3) 
- 
minimum (min) and maximum (max)  
for subjects with data. Additionally, the geometric mean (GeoMean), geometric standard deviation 
(GSD), and geometric coefficient of variation (GCV) will be displayed for certain variables. Values of 
‘0’ will be removed from the calculation of the geometric mean, GSD, and GCV. 
Mean, geometric mean, median, and the quartiles will be presented to one more decimal place than the 
raw value. The minimum and maximum values will be presented with the same decimal precision as 
the raw value. SD, GSD, and GCV will be reported to two decimal places greater than the original 
value. 
For qualitative (categorical) variables, the frequency count (n) and percentage (%) of subjects with non-
missing data per category will be the default frequency tabulations. Where appropriate and present, the 
number of missing values will be displayed as “Missing” category. 
Percentage values are to be presented to one decimal place, for example, 52.3%. 
The denominator used for calculation of the percentages will be specified in a footnote to the tables for 
clarification. 
4.2 
Statistical Output Layout 
All titles and column headers (consisting of one or several words) will be capitalised; articles, 
prepositions, and conjunctions, and “To” in infinitives will not be capitalised, except they are at the 
beginning of titles or headers. 
All pages will be numbered according to the table/listing/figure to which the page belongs to. Every 
table/listing/figure will be numbered from page 1, “Page X of Y” at the bottom of each page. 
The definition of baseline and endpoint value will be described in a footnote in every TLF where 
applicable. Other important definitions will also be presented if necessary. 
Dates will be listed in the format: yyyy-mm-dd (e.g. 2003-11-20). Times will be listed in the format: 
hh:mm (e.g. 09:15) or in the format hh:mm:ss if seconds are collected. When the date and time are 
collected, these are listed in the format: yyyy-mm-ddThh:mm (e.g. 2003-11-20T09:15), 
yyyy-mm-ddThh, or yyyy-mm-ddThh:mm:ss.  
Partially missing dates will be listed in the format yyyy-mm (e.g. 2013-11) if only day is missing or in 
the format yyyy (e.g. 2013) if month and day are missing. 
Missing data including missing dates or times will be displayed in listings as blank fields, unless 
otherwise specified. 
Listings will be sorted by subject’s number and visit number where applicable, unless specified 
otherwise.

Treatment Day Numbering 
All assessment dates will be related to the first day of IMP intake during the first treatment period. This 
first day of IMP intake is referred to as Day 1. Day –1 is the day that is preceding Day 1 and Day 0 will 
not be defined. 
Treatment days may alternatively be numbered in listings with reference to the ongoing treatment period 
using the following rules: 
- 
Dates prior to or during the first treatment period will be numbered with reference to the date 
of first IMP intake as described above. 
- 
Dates belonging to the second and third treatment periods will be numbered with reference to 
the day after visit V1C or V2C respectively. 
- 
Treatment days during any treatment period will be labelled according to the planned treatment 
sequence of the subject (e.g. A-11 for day 11 of the first treatment period in the sequence ABC). 
Treatment days prior up to visit VR will be labelled without reference to treatment sequence. 
4.6 
Trial Periods 
Baseline period 
The baseline period will be defined as the period from informed consent signature date to the date of 
visit VR. 
Treatment periods 
The periods from the day after visits VR, V1C, and V2C, to the dates of visits V1B, V2B, and V3B 
respectively, will be defined as the three treatment periods of this trial. 
Data collected at visits V1B, V2B, and V3B will be considered as end-of-treatment values for their 
respective treatment periods. 
If an early discontinuation visit (EDV) occurs after 7 or more IMP intakes, and not more than 3 days 
after the last IMP intake, the data collected at the EDV will be assigned to the end of the ongoing 
treatment period for statistical analyses. 
 
Washout periods 
The periods from the day after visits V1B and V2B, to the dates of visits V1C and V2C respectively 
will be defined as the two washout periods of this trial. 
Data collected at visits V1C and V2C will be considered as end-of-washout values for the first and 
second treatment periods respectively and will be summarised within the same treatment as the end-of-
treatment values of the respective treatment period. 
If an EDV occurs 6 or more days after the last IMP intake of the preceding treatment period, the data 
collected at the EDV will be assigned to the end of the ongoing washout period for statistical analyses. 
Follow-up period 
The follow-up period is a trial period starting with the day after visit V3B/EDV until the trial termination 
date.

Baseline and Endpoint Values 
Baseline value 
The baseline value for a variable is defined as the last non-missing value collected before or during visit 
VR. 
For diary data, the baseline value will be the value standardised as described in Section 5.6.8 over the 
baseline period. 
Endpoint value 
The endpoint value for a variable is defined as the last non-missing value collected during any 
end-of-treatment visit (V1B, V2B, or V3B). 
For diary data, the endpoint value will be the value standardized as described in Section 5.6.8 over any 
treatment period corresponding to a given treatment. 
Absolute change from baseline will be calculated as 
𝐴𝑏𝑠𝑜𝑙𝑢𝑡𝑒 𝐶ℎ𝑎𝑛𝑔𝑒 𝑓𝑟𝑜𝑚 𝐵𝑎𝑠𝑒𝑙𝑖𝑛𝑒 𝑎𝑡 𝑉𝑖𝑠𝑖𝑡 𝑋= 𝑉𝑎𝑙𝑢𝑒 𝑎𝑡 𝑉𝑖𝑠𝑖𝑡 𝑋−𝐵𝑎𝑠𝑒𝑙𝑖𝑛𝑒 𝑉𝑎𝑙𝑢𝑒 
Relative change from baseline (%) will be calculated as 
𝑅𝑒𝑙𝑎𝑡𝑖𝑣𝑒 𝐶ℎ𝑎𝑛𝑔𝑒 𝑓𝑟𝑜𝑚 𝐵𝑎𝑠𝑒𝑙𝑖𝑛𝑒 𝑎𝑡 𝑉𝑖𝑠𝑖𝑡 𝑋= 𝑉𝑎𝑙𝑢𝑒 𝑎𝑡 𝑉𝑖𝑠𝑖𝑡 𝑋−𝐵𝑎𝑠𝑒𝑙𝑖𝑛𝑒 𝑉𝑎𝑙𝑢𝑒
𝐵𝑎𝑠𝑒𝑙𝑖𝑛𝑒 𝑉𝑎𝑙𝑢𝑒
× 100 
Note: Subjects with a baseline value of ‘0’ will be excluded from the calculation of relative change. 
 
4.8 
Treatment Assignment 
In summaries and analyses where data is pooled by treatment, assignment to treatments will be 
performed as follows: 
• 
Data collected up to and including visit VR (baseline) will be assigned to all treatments. 
• 
Data collected at visits V1A-V1C, V2A-V2C, V3A-V3B, will be assigned to the treatment 
corresponding to the first, second and third treatment period respectively 
• 
Data collected at the EDV visit will be assigned to treatment periods according to the rules in 
Section 4.6 
• 
Efficacy analyses will be performed according to treatment as randomised. Data will be assigned 
to treatments based on the combination of planned treatment sequence and treatment period. 
• 
Safety analyses will be performed according to treatment as treated. Data will be assigned to 
treatments based on the treatment actually received during the corresponding treatment period. 
Other features of or deviations from the rules of treatment assignment are discussed in the relevant 
sub-sections of Section 5.

Coding Systems and Conventions 
4.9.1 
Coding of adverse events and medical history 
Adverse event and medical history investigator terms are assigned to a lowest level term (LLT) and a 
preferred term (PT) and will be classified by high level term (HLT), high level group term (HLGT) and 
system organ class (SOC) according to the Medical Dictionary for Regulatory Activities (MedDRA), 
Version 21.0 [2]. 
4.9.2 
Coding of medications 
Medications are classified according to active drug substance using the World Health Organization-
Drug Dictionary Enhanced (WHO-DDE), 2018 March version [3]. The WHO drug code has 11 digits. 
The generic name is defined by the first 6 of the 11 digits. In addition, the Anatomical Therapeutic 
Chemical (ATC) classes are assigned to the drug code. In this trial, ATC codes are defined to the 4th 
level. 
4.10 Handling of Missing Data 
Data imputation methods will not be used in the analysis of efficacy or safety data. Efficacy data will 
be assumed to be missing at random (MAR), and likelihood-based estimation methods robust to this 
form of missingness will be used in efficacy analysis. Other details of handling of missing data, where 
applicable, are discussed in the relevant sub-sections of Section 5 (STATISTICAL ANALYSIS: 
DEFINITIONS, DERIVATIONS, CALCULATIONS AND METHODOLOGY).

Protocol Deviations 
All analysis sets are defined in Section Error! Reference source not found.. The per protocol (PP) set 
is defined as all subjects who have completed the trial without major protocol deviation. 
During the Blind Data Review (BDR) the eligibility of subjects for the PP set will be assessed. The 
BDR will be performed after data entry, prior to locking the database. All decisions made during the 
BDR will be documented in the BDR report before the closure of the database. 
Protocol deviations are deviations from the procedures outlined in the clinical trial protocol or from 
subsequent protocol-related instructions like missed evaluations, incorrect timing of evaluations, 
non-compliance with the IMP, intake of prohibited medications or any non-adherence to the clinical 
trial protocol that impacts subject’s rights, safety or welfare. Protocol deviations that may affect the 
efficacy or PK outcome will be discussed during the BDR. 
An appropriate clinical trial team, including a physician, will review potential protocol deviations and 
relevant information regarding those deviations to determine a possible impact on safety or efficacy 
endpoints. A decision will be made as to the effect of the possible deviations to determine if it is 
considered major or minor. The status, major or minor, of each protocol deviation will be documented 
in the BDR report. A subject may have one or more major protocol deviations resulting in the exclusion 
of that subject from the per protocol analysis set. 
Reference listings will also be made available to help with the review of the protocol deviations. 
Note: Protocol deviations will, if possible, be validated against data recorded in the eCRF. Note where 
an answer for an inclusion/exclusion tick box differs from the algorithmic check of the criteria, the 
algorithmic check will overrule the tick box. 
Protocol deviations of the following categories and respective data listings will be reviewed during the 
BDR.

Prior and Concomitant Medications 
Prior and concomitant medications and therapies are documented in the eCRF. 
The following information is collected: 
- Medication / therapy name 
- Indication (Parkinson’s disease, excessive daytime sleepiness, medical history diagnosis – 
specified, adverse event – specified, other) 
- Route 
- Total daily dose (units) 
- Frequency 
- Start date 
- Stop date (or ongoing) 
Medications and therapies will be classified as ‘prior’, ‘concomitant’ or ‘post-treatment’ based on 
start/stop dates: 
- Prior medications/therapies are defined as those medications/therapies starting and ending 
prior to the first IMP intake as recorded in the eCRF. 
- Concomitant medications/therapies are defined as medications/therapies started at or after 
the first IMP intake as recorded in the eCRF and include medications/therapies started prior 
to the first IMP intake but continued during the trial. 
- Post-treatment medications/therapies are defined as medications/therapies which started 
after the last IMP intake as recorded in the eCRF. 
If the start date of medication/therapy is incomplete or missing, it will be assumed to be concomitant 
except if the incomplete start date or the stop date indicates that the medication/therapy started prior 
to the first IMP intake or after the last IMP intake. 
Concomitant medications will be assigned to treatments based on the preceding IMP intake. 
Medications taken during a washout period will be assigned to the treatment of the IMP taken in the 
preceding treatment period. If the start or end date indicates that the medication was taken concurrently 
with multiple treatments, it will be assigned to every corresponding treatment. If the start or end date is 
incomplete such that it could belong to more than one treatment, the concomitant medication will be 
assigned to all such treatments.

Exposure to IMP and Compliance 
5.4.1 
Exposure to IMP 
Exposure data from eCRF includes: 
- 
date of first IMP intake  
- 
date of last IMP intake 
- 
date of IMP dispensed 
- 
number of capsules dispensed (modafinil and flecainide) 
- 
date of IMP returned 
- 
number of capsules returned (modafinil and flecainide) 
Exposure data from the subject treatment diaries includes: 
- 
date 
- 
number of capsules taken (modafinil and flecainide) 
The date of first IMP intake is the intake of the first morning dose as recorded in the eCRF. If the date 
of first intake as recorded in the eCRF is missing, the first IMP intake recorded in the subjects’ diaries 
will be used. 
The date of last IMP intake is the date of last IMP intake recorded at trial termination page. If the date 
of last intake of the last evaluated dose is missing, the last IMP intake recorded in the subject diaries 
will be used. 
The treatment period duration will be calculated in days as follows:  
𝑡𝑟𝑒𝑎𝑡𝑚𝑒𝑛𝑡 𝑝𝑒𝑟𝑖𝑜𝑑 𝑑𝑢𝑟𝑎𝑡𝑖𝑜𝑛 (𝑑𝑎𝑦𝑠) = 𝑒𝑛𝑑-𝑜𝑓-𝑡𝑟𝑒𝑎𝑡𝑚𝑒𝑛𝑡 𝑣𝑖𝑠𝑖𝑡 𝑑𝑎𝑡𝑒−𝑏𝑎𝑠𝑒𝑙𝑖𝑛𝑒 𝑣𝑖𝑠𝑖𝑡 𝑑𝑎𝑡𝑒 
For the purposes of treatment period duration calculation, visit VR as well as end-of-washout visits 
V1C and V2C are considered as baseline visits. 
Treatment duration based on IMP exposure data will be calculated for each treatment period as:  
𝑡𝑟𝑒𝑎𝑡𝑚𝑒𝑛𝑡 𝑑𝑢𝑟𝑎𝑡𝑖𝑜𝑛 (𝑑𝑎𝑦𝑠) = 𝑙𝑎𝑠𝑡 𝐼𝑀𝑃 𝑖𝑛𝑡𝑎𝑘𝑒 𝑑𝑎𝑡𝑒 −𝑓𝑖𝑟𝑠𝑡 𝐼𝑀𝑃 𝑖𝑛𝑡𝑎𝑘𝑒 𝑑𝑎𝑡𝑒 + 1 
within the respective treatment period. The overall treatment and treatment period durations will be 
calculated as the sum of corresponding individual durations. 
The following will be provided:

The default summary statistics of treatment period duration and treatment duration will be presented by 
period and overall. 
5.4.2 
Compliance 
Compliance based on the eCRF and subject diaries will be calculated as follows: 
𝑒𝐶𝑅𝐹 𝑐𝑜𝑚𝑝𝑙𝑖𝑎𝑛𝑐𝑒 (%) = 100 ∗(𝑁 𝑡𝑎𝑏𝑙𝑒𝑡𝑠 𝑑𝑖𝑠𝑝𝑒𝑛𝑠𝑒𝑑−𝑁 𝑡𝑎𝑏𝑙𝑒𝑡𝑠 𝑟𝑒𝑡𝑢𝑟𝑛𝑒𝑑)

𝑡𝑟𝑒𝑎𝑡𝑚𝑒𝑛𝑡 𝑑𝑢𝑟𝑎𝑡𝑖𝑜𝑛∗𝑁 𝑡𝑎𝑏𝑙𝑒𝑡𝑠 𝑝𝑟𝑒𝑠𝑐𝑟𝑖𝑏𝑒𝑑 𝑝𝑒𝑟 𝑑𝑎𝑦 
The default number of tablets prescribed per day is 2 tablets of modafinil and flecainide, for a total of 
4 tablets per day. For subjects older than 65 years of age at visit VS1, on the first three days of each 
treatment period the dosage is halved, resulting in one tablet of modafinil and flecainide scheduled to 
be taken for a total of 2 tablets per day.

- outcome (recovered/resolved, recovered/resolved with sequelae, recovering/resolving, not 
recovered/not resolved, fatal, unknown) and date of outcome 
- serious (yes or no) 
All AEs will be presented in listings. 
Adverse event summaries will focus on treatment-emergent adverse events (TEAEs), defined as AEs 
with an onset or worsening after the first IMP intake and not more than 7 days after the last IMP intake. 
If the start date of an AE is incomplete or missing, it will be assumed to be treatment-emergent except 
if the stop date or the incomplete start date indicates that the event started prior to the first IMP intake 
or later than 7 days after the last IMP intake. 
Treatment-emergent adverse events will be assigned to treatments based on the treatment period 
containing the AE onset date. If the onset date of an adverse event is during a washout period, it will be 
assigned to the preceding treatment period. If the AE onset date is incomplete such that it could belong 
to more than one treatment period, the AE will be assigned to all treatments corresponding to such 
treatment periods. 
Based on collected data the following will be determined and will be used in addition to AEs overall 
for presentation in the applicable tables and listings: 
- Serious Adverse Events (SAEs): defined as AEs considered by the investigator as serious. 
- Related TEAEs: defined as AEs with relationships to the IMP assessed as being “possible”, 
“probable” or “definite” and include AEs with missing IMP relationship assessments. 
- Unrelated TEAEs: defined as AEs with relationships to the IMP assessed as being “unlikely” 
or “unrelated”.  
- Severe TEAEs: defined as AEs assessed as being “severe” in intensity and include the events 
with missing severity assessment. 
- TEAEs leading to discontinuation: defined AEs whose action taken with IMP is “drug 
withdrawn” or other action taken is “withdrawal from trial”. 
- TEAEs leading to death: selected as those events where outcome of event is indicated as 
“fatal”. 
The duration of the AE will be calculated using the following formula: 
𝐴𝐸 𝐷𝑢𝑟𝑎𝑡𝑖𝑜𝑛 (𝑑𝑎𝑦𝑠) = 𝐴𝐸 𝑠𝑡𝑜𝑝 𝑑𝑎𝑡𝑒−𝐴𝐸 𝑠𝑡𝑎𝑟𝑡 𝑑𝑎𝑡𝑒+ 1 
If the start or stop dates of the AE are incomplete or AE is still ongoing at the end of the trial, the 
duration will not be calculated.

Movement Disorder Society-Sponsored Version of Unified Parkinson's Disease Rating 
Scale (MDS-UPDRS) 
An MDS-UPDRS questionnaire is administered on visits VR, V1B, V2B, and V3B/EDV. The MDS-
UPDRS consists of four parts: 
1. Non-motor aspects of experiences of daily living (13 items) 
2. Motor aspects of experiences of daily living (13 items) 
3. Motor examination (33 scores based on 18 items) 
4. Motor complications (6 items) 
with each item being scored using an integer rating of 0 to 4.  
A score will be calculated for each part of the MDS-UPDRS as the sum of all items in that part of the 
questionnaire. According to Goetz et al. [5], a valid score for the MDS-UPDRS parts can be calculated 
if the respective part contains a number of missing values less than or equal to the following: 
- 
Non-motor aspects of experiences of daily living – 1 
- 
Motor aspects of experiences of daily living – 1 
- 
Motor examination – 3 
- 
Motor complications – 0 
For subjects with partially missing data, a prorated score will be calculated by taking the sum of all non-
missing items, dividing it by the number of non-missing items, and multiplying it by the total number 
of items in each part. The prorated score will be rounded to the nearest whole number. 
The total MDS-UPDRS score will be calculated as the sum of the scores of each part. The total score 
will not be calculated if the score for any part of the MDS-UPDRS is missing. 
The following table and listing will be presented:

The QUIP-RS consists of four primary questions, each applied to four ICDs (compulsive gambling, 
buying, eating and sexual behaviour) and three related disorders (medication use, punding and 
hobbyism). The QUIP-RS uses a 5-point scale (score 0-4 for each question) to rate the severity of each 
symptom based on its weekly frequency. The total ICD score ranges from 0 to 64, and the total 
QUIP-RS score for all ICDs and related disorders ranges from 0 to 112.

Efficacy Analysis 
Efficacy will be assessed by evaluation of the following variables: 
- Epworth Sleepiness Scale (ESS) score change from baseline at the end of each treatment 
period 
- ESS score responder rate at the end of each treatment period 
- Absence of residual somnolence at the end of each treatment period 
- Psychomotor Vigilance Test (PVT) variable change from baseline at the end of each 
treatment period 
- Montreal Cognitive Assessment (MoCA) score change from baseline at the end of each 
treatment period 
- Actimetry change from baseline at the end of each treatment period 
- Number and duration of diurnal involuntary sleep attacks (subject diaries) change from 
baseline at the end of each treatment period 
- Episodes of somnolence (subject diaries) change from baseline at the end of each 
treatment period 
The Full Analysis set as well as the Per Protocol set will be used for the analysis of efficacy data.  
Treatment periods will be considered as evaluable for efficacy analysis only if the following rules 
are satisfied: 
• 
IMP is taken for at least 7 days during the treatment period 
• 
Last IMP intake is at most 3 days before the corresponding end-of-treatment visit, i.e. a 
maximum of 3 IMP intakes can be missed leading up to the end-of-treatment visit. 
Washout periods will be considered as evaluable for efficacy analysis only if the preceding treatment 
period is evaluable and the last IMP intake is 6 or more days before the corresponding end-of-washout 
visit. 
For the purposes of these rules, EDVs are considered as end-of-treatment (if the preceding scheduled 
visit was VR/V1C/V2C) or end-of-washout (if the preceding scheduled visit was V1B/V2B) visits. 
A trial period not being evaluable for efficacy analysis according to these rules is considered a major 
protocol deviation. 
Efficacy analyses for the FAS will be performed using data available from all scheduled visits, as well 
as EDV visits satisfying the above criteria. Efficacy analyses for the PP will be performed using only 
data from trial periods unaffected by major protocol deviations. 
5.6.1 
Key Efficacy Analysis 
On visits VS1, VR, V1B, V1C, V2B, V2C, and V3B/EDV subjects will fill out the Epworth 
Sleepiness Scale (ESS) questionnaire. The ESS consists of 8 questions with the answers on the scale 
of 0-3. The ESS score is the sum of the 8 items and has a range of 0-24. The key efficacy variable in 
this trial is the change from baseline of the ESS score at the end of each treatment period (visits V1B, 
V2B, and V3B/EDV). 
The ESS score change from baseline will be analysed using a mixed linear regression model with the 
fixed effects of treatment, period, treatment by period interaction, sequence, and baseline score, and 
subject nested within sequence as a random effect. The model will be estimated using the restricted 
maximum likelihood method (REML). Degrees of freedom for the fixed effects will be estimated 
using the Kenward-Roger approximation.

A statistically significant (p-value < 0.05) treatment by period interaction may indicate the presence of 
residual treatment (carryover) effects, which may bias the estimates of treatment effects. For this 
reason, if a statistically significant treatment by period interaction is found in the analysis of the key 
efficacy endpoint, the key efficacy analyses will be performed using data from the first period only. In 
such an event, the key efficacy endpoint will be modelled using an analysis of covariance (ANCOVA) 
model with the fixed effect of treatment and baseline score as a covariate. 
The following SAS code will be used in the analysis of first-period data: 
PROC MIXED DATA=<Dataset> METHOD=REML;

Key Efficacy Endpoint Carryover Effect Estimation 
If the key efficacy endpoint analysis shows a statistically significant treatment by period interaction (p-
value < 0.05), modified key efficacy analyses will be performed to adjust for potential first-order 
carryover effects on the ESS score. For these analyses, the treatment of the previous treatment period 
will be assigned to each observation. The treatment by period interaction in the original efficacy model 
will not be included. 
The treatment effects at end-of-treatment visits V1B, V2B and V3B will be estimated using a mixed 
linear regression model with the fixed effects of treatment, period, sequence, and residual treatment, 
baseline score as a covariate, and the random effect of subject nested within sequence. The carryover

ESS Responder Rate 
The Epworth Sleepiness Scale (ESS) responder rate is defined as the proportion of subjects with a 
relative ESS score change from baseline of at least -25% after each treatment period. 
The treatment differences in the ESS responder rate will be assessed using a generalised linear mixed 
regression model (GLMM) with the fixed effects of treatment, period, treatment by period interaction, 
sequence, and baseline score, and subject nested within sequence as a random effect. The logit link 
function will be used to model the binary response data. The model will be estimated using the default 
RSPL method. Degrees of freedom for the fixed effects will be estimated using the Kenward-Roger 
approximation. 
The following SAS code will be used in GLMM estimation: 
PROC GLIMMIX DATA=<Dataset> METHOD=RSPL; 
 
CLASS <Subject> <Treatment> <Period> <Sequence>; 
 
MODEL <Responder Status> = <Treatment> | <Period>

/ DIST=BINARY LINK=LOGIT DDFM = KENROG; 
 
RANDOM int / SUBJECT=<Subject>(<Sequence>); 
 
LSMEANS <Treatment> / PDIFF ODDSRATIO ILINK CL;  
RUN; 
The treatment least-squares means of the log-odds will be reported as well as their standard errors and 
95% confidence intervals. Also, the odds ratios between each treatment will be displayed with 95% 
confidence intervals. 
In case of model non-convergence, the treatment by period interaction will be removed from the 
model. If the simplified model fails to converge, the difference in response rate between treatments 
will be evaluated using an exact McNemar’s test. Response at endpoint will be compared between 
each treatment at the two-sided 5% level. 
McNemar’s test will be performed using the following SAS code: 
PROC FREQ DATA=<Dataset>; 
 
TABLES <Treatment 1 Response>*<Treatment 2 Response>; 
 
EXACT MCNEM; 
RUN; 
If a statistically significant (p-value < 0.05) treatment by period interaction is found in the analysis of 
the ESS responder rate, an additional analysis will be performed using only data collected during the 
first treatment period. If the full GLMM specification was not used due to model non-convergence, 
this additional analysis will be performed in case of a statistically significant treatment by period 
interaction in the key efficacy model (Section 5.6.1). 
Model-based analysis of first-period data will be based on a generalised linear model (GLM) with the 
fixed effect of treatment and baseline as a covariate. The following SAS code will be used: 
PROC GLIMMIX DATA=<Dataset>;

treatment period will be analysed using statistical methods described in Section 5.6.3.  
In the case that a statistically significant (p-value < 0.05) treatment by period interaction is found in

Psychomotor Vigilance Test (PVT) 
On visits VR, V1B, V1C, V2B, V2C, and V3B/EDV subjects will undergo 3-minute Psychomotor 
Vigilance Task evaluations. PVT will be performed up to four times during each visit: at 10:00 h, 
12:00 h, 14:00 h, and 16:00 h (±15 minutes each) by default. If the default PVT schedule is too 
burdensome for a particular subject, it may be individually adapted to at least 3 assessments with a 
time window of at least 1 hour between each PVT assessment. The actual time of each PVT 
assessment will be collected in the eCRF. 
The following PVT variables will be collected at every visit and timepoint: 
- 
Mean response time (ms) 
- 
Number of lapses 
- 
Number of total errors

A failure to react or any reaction exceeding 500 ms is considered a lapse. A reaction without stimulus 
or under 100 ms is considered a false start. Lapses and false starts are counted towards total errors. 
For each PVT variable, the mean value during a visit will be used for analysis. 
The PVT mean response time will be analysed using a mixed linear regression model as described in 
Section 5.6.1. 
In the case that a statistically significant (p-value < 0.05) treatment by period interaction is found in

Montreal Cognitive Assessment (MoCA) 
The Montreal Cognitive Assessment (MoCA) is a brief screening instrument to detect mild cognitive 
impairment. The MoCA assesses multiple cognitive domains including attention, concentration, 
executive functions, memory, language, visuospatial skills, abstraction, calculation and orientation. 
Subjects will complete the MoCA during the screening and washout visits VS1, VR, V1C, and V2C, 
and on end-of-treatment visits V1B, V2B, and V3B/EDV. 
To decrease possible learning effects, the three (equivalent) versions 7.1, 7.2, and 7.3 will be used in 
alternation. MoCA scores range between 0 and 30. A score of 26 or over is considered to be normal.

Actigraphy (Inactivity) Evaluation 
Actigraphy is a non-invasive method of monitoring a person's rest and activity cycles. The movements 
the actigraphy sensor undergoes are continually recorded.  
Actigraphy measurements will be collected for 3 days prior to visit VR and for 3 days at the end of each 
treatment period. Charged actigraphy devices will be handed out to subjects at visits VS1, VR, V1C, 
and V2C, and actigraphy data will be collected during visits VR, V1B, V2B, and V3B/EDV. 
Objective activity measures will be estimated from the raw activity data by a research team from 
 and provided to
 for efficacy analysis. A description of this process and each 
evaluated objective activity measure is provided in the AX3 Analysis Plan, attached as an appendix to 
this SAP (see Section 9). 
The following objective activity measures will be estimated for each day prior to the collection visit: 
- Night Time Immobility Duration (minutes) (NTID) 
- Night Time Mobility Periods (NTMP) 
- Night Time Mobility Duration (minutes) (NTMD) 
- Diurnal Immobility Periods (DIP) 
- Diurnal Immobility Duration (minutes) (DID) 
- Daily Physical Activity (g) (DPA) 
- Nightly Physical Activity (g) (NPA) 
- Daily Jerk (g/s) (DJ) 
The following activity ratios will be estimated once per collection visit: 
- Intradaily Variability (IV) 
- Interdaily Stability (IS) 
- Relative Amplitude (RA) 
The results of each activity measure will be summarised at each visit. The mean value of assessments 
corresponding to the collection visit will be used for analysis. All values will be listed.

Activity ratios (IV, IS, RA) and physical activity variables (DPA, DJ) will additionally be analysed 
using a mixed linear regression model as described in Section 5.6.1. 
In the case that a statistically significant (p-value < 0.05) treatment by period interaction is found in 
the analysis of an objective actigraphy measure, an additional analysis will be performed for that 
activity measure using only data collected during the first treatment period. The statistical model will 
be adjusted as described in Section 5.6.1. 
Further statistical analyses of actigraphy data are defined outside the scope of this SAP.

Subject Diary Data 
Over the course of the trial, subjects will fill out paper-based diaries concerning their daily sleep and 
IMP intake patterns. One screening diary and three treatment diaries will be issued at visit VS1, and 
visits VR, V1C, and V2C respectively, and collected at visits VR, V1C, V2C, and V3B/EDV. The 
diaries will be filled in continuously from visit VS1 to V3B/EDV, including the washout periods after 
treatment periods I and II. 
Analysis of drug exposure data collected from subject diaries is discussed in section 5.4.1. 
Efficacy-related data collected from patient diaries will be summarized over the respective trial period 
(baseline, washout 1, washout 2, and treatment 1, 2, or 3) for the purpose of displaying them in 
summaries. Numeric variables will be standardized to amount per day, and for categorical variables 
subjects will be included in every category that occurred to them in the given period. 
If there are less than 3 non-missing values over the course of a treatment or washout period for a 
given variable, it will be set to missing for the respective period in summaries. For treatment periods, 
only the last 3 non-missing values per parameter will be aggregated in summaries order to capture the 
full effect of the IMP. 
All diary data will be listed.

Diurnal Involuntary Sleep Attacks 
The number and total duration of diurnal involuntary sleep attacks will be recorded in the subject 
diaries. These data will be summarised as numeric variables as described in section 5.6.8. 
The following tables will be presented: 
Table 15.3.14.1.S Summary of Diurnal Involuntary Sleep Attacks – Full Analysis 
Table 15.3.14.2.T Summary of Diurnal Involuntary Sleep Attacks – Full Analysis 
The number and duration of diurnal involuntary sleep attacks will be summarised using default 
summary statistics for each trial period. The change from baseline will be displayed for each post-
baseline period. 
5.6.8.2 
Somnolence Episodes 
The number of somnolence episodes each day will be collected in the subject diaries. It will be 
summarised as a numeric variable as described in section 5.6.8.

Other Efficacy-Related Variables 
Other efficacy-related variables collected in the subject diaries include: 
• 
Get-up time 
• 
Total time (hours) slept last night 
• 
Wake-up periods during night sleep: 
o Number (<5, between 5 and 10, >10) 
o Total duration (minutes) 
• 
Voluntary naps: 
o Number 
o Total duration (minutes) 
• 
Number of caffeinated drinks 
• 
Going-to-bed time 
Time in bed will be calculated as the difference in hours between the get-up time and the going-to-
bed time of the preceding day. Time in bed will not be calculated if either of the datetime values are 
completely or partially missing. 
Adjusted total time slept in hours will be calculated as follows: 
𝐴𝑑𝑗.  𝑡𝑜𝑡𝑎𝑙 𝑡𝑖𝑚𝑒 𝑠𝑙𝑒𝑝𝑡= 𝑚𝑖𝑛(𝑡𝑜𝑡𝑎𝑙 𝑡𝑖𝑚𝑒 𝑠𝑙𝑒𝑝𝑡,   𝑡𝑖𝑚𝑒 𝑖𝑛 𝑏𝑒𝑑−𝑤𝑎𝑘𝑒−𝑢𝑝 𝑝𝑒𝑟𝑖𝑜𝑑 𝑑𝑢𝑟𝑎𝑡𝑖𝑜𝑛) 
With the exception of the number of wake-up periods during night sleep, these data will be 
summarised as numeric variables as described in section 5.6.8.

Pharmacokinetic Analysis 
To assess the steady state pharmacokinetics of the IMP, blood samples will be collected upon subject 
arrival at study sites during visits VR, V1B, V1C, V2B, V2C, and V3B/EDV. Concentrations of 
flecainide and modafinil at each visit will be summarised. For summaries, concentrations below the 
lower limit of quantification (LLOQ) will be set to zero. Concentrations will be reported as collected in 
listings. 
To summarise pharmacokinetic data the geometric mean (GeoMean), geometric standard deviation 
(GSD), and geometric coefficient of variation (GCV) will be displayed. These statistics will be 
calculated using the following formulae: 
𝐺𝑒𝑜𝑀𝑒𝑎𝑛= √𝑦1 × 𝑦2 × … × 𝑦𝑛
𝑛
 
𝐺𝑆𝐷= 𝑒(𝑆𝐷(𝑙𝑛(𝑦1),𝑙𝑛(𝑦1),…,𝑙𝑛(𝑦𝑛))) 
𝐺𝐶𝑉= √𝑒𝐺𝑆𝐷2 −1 ×  100%,  
where n – number of observations, SD – standard deviation, ln – natural logarithm. Values of ‘0’ will 
be removed from the calculation of the geometric mean, GSD, and GCV. The ratios GeoMean ÷× GSD 
will be displayed in addition to these statistics. 
Evaluability of pharmacokinetic data 
PK samples performed at the end of treatment periods will be analysed if an IMP intake was performed 
in the morning before the PK sample. 
PK samples performed at the end of washout periods will be analysed if the last IMP intake is 6 or 
more days before the PK sample, and if the preceding end-of-treatment PK sample is evaluable 
according to the above rule. 
Deviations from these rules will be considered as major protocol deviations in relation to PK analysis. 
 
The following tables and listing will be presented: 
Table 15.4.1.S Summary of Pharmacokinetics Concentrations – PK Analysis Set 
Table 15.4.2.T Summary of Pharmacokinetics Concentrations – PK Analysis Set 
The concentrations of modafinil and flecainide at each visit will be summarised using the geometric 
mean, geometric standard deviation, and geometric coefficient of variation in addition to the default 
summary statistics.
