Objectives: 
Primary: 
To evaluate the efficacy of TNX-102 SL (cyclobenzaprine HCl sublingual tablets) in the treatment of 
military-related posttraumatic stress disorder (PTSD) 
Secondary: 
To evaluate the safety of TNX-102 SL (cyclobenzaprine HCl sublingual tablets) in the treatment of 
military-related posttraumatic stress disorder (PTSD) 
Methodology:  
This is a 12-week, multicenter, randomized, double-blind, placebo-controlled, fixed-dose study that 
will investigate the efficacy and safety of 5.6 mg TNX-102 SL (2 x 2.8 mg tablets)—a sublingual 
formulation of cyclobenzaprine.  Following successful screening and randomization, eligible patients 
will have a telephonic visit at week 2 and then return regularly to the study clinic for monthly visits 
for assessments of efficacy and safety. 
There will be a total of 6 study visits over approximately 13-17 weeks of study participation, 
including Screening (Visit 1), Randomization (Day 0, Visit 2), a phone visit after 2 weeks of 
treatment and in-clinic visits after 4, 8, and 12 weeks of treatment.  A total of approximately 550 
patients will be randomized in a 1:1 ratio to placebo or TNX-102 SL 5.6 mg (2 x 2.8 mg tablets). 
Approximately 15 patients that successfully completed the TNX-CY-P301 study will be invited back 
to participate in a post-study pharmacogenomic assessment.

INTRODUCTION 
TNX-102 SL is a tablet for sublingual administration containing cyclobenzaprine HCl [3-(5H-
dibenzo[a,d]cyclohepten-5-ylidene)-N,N-dimethyl-1-propanamine hydrochloride].  TNX-102 SL 
2.8 mg tablets are under development by Tonix Pharmaceuticals, Inc. (Tonix) as a treatment for 
posttraumatic stress disorder (PTSD). 
The active ingredient in TNX-102 SL, cyclobenzaprine HCl (CBP), has been approved for use in 
the United States (US) since 1977, originally as FLEXERIL® 10-mg oral tablets indicated as an 
adjunct to rest and physical therapy for the relief of muscle spasm associated with acute, painful 
musculoskeletal conditions.  The usual dose for this indication is 30 mg or 15 mg per day taken 
as 10 mg TID or 5 mg TID, respectively.  The FLEXERIL brand of immediate-release (IR) 
cyclobenzaprine tablets has been discontinued since May 2013.  Generic cyclobenzaprine is 
available and marketed in a variety of strengths including 5-, 7.5- and 10-mg IR tablets. 
AMRIX® (AMRIX® Prescribing Information, 2016), an extended-release capsule of 
cyclobenzaprine was approved in 2007 in the US as a New Drug Applications (NDA) and is 
currently available in 15- and 30-mg, taken once a day for the same indication as FLEXERIL in 
the US.  Both FLEXERIL and AMRIX are indicated for 2-3 weeks use only.  No 
cyclobenzaprine product has been approved for use in PTSD by Food and Drug Administration 
(FDA), Health Canada, or in any other country. 
As its primary pharmacologic action in relief of muscle spasm, cyclobenzaprine has been shown 
to decrease skeletal muscle hyperactivity in several animal models through central mechanisms 
involving blockade of either α2-adrenoreceptors (Barnes et al, 1980) (AR) or serotoninergic 5-
HT2A receptors (Kobayashi et al, 1996; Honda et al, 2003).  Cyclobenzaprine acts primarily in 
the central nervous system (CNS) at the brain stem rather than at the spinal cord level, and does 
not act directly at the neuromuscular junction or directly on skeletal muscle. 
In addition to these primary pharmacologic actions, cyclobenzaprine has been observed to 
increase restorative sleep in fibromyalgia patients, which was correlated with improvement in 
daytime symptoms in a proof-of-concept study conducted by Vela Pharmaceuticals (Protocol No. 
VPI CY 0001.1) (Moldofsky et al, 2011) using low dose cyclobenzaprine (TNX-102 capsules).  
The rationale for testing cyclobenzaprine as a treatment for PTSD is based on known effects of 
cyclobenzaprine on CNS receptors and, in part, on the relationship of fibromyalgia and PTSD to 
disturbed and non-restorative sleep. 
PTSD is characterized by symptom clusters that include re-experiencing (intrusion) symptoms, 
avoidant behaviors, negative mood and cognitions, and heightened arousal and reactivity, the 
array of which develops and persists following exposure to a severely traumatic event.  It is well 
established that sleep disturbances are common among individuals with PTSD that has 
developed in response to combat traumas (Mellman et al, 1995; Pietrzak et al, 2010; Neylan et 
al, 1998) and sexual assault (Steine et al, 2012), including military sexual trauma (Kelly et al, 
2011).  Among military personnel returning from OEF/OIF/OND deployments to Afghanistan 
and Iraq, sleep disturbances are considered the most frequent and severe of the PTSD symptoms 
(McLay et al, 2010).  Sleep disturbances are considered core features of PTSD and are 
components of two of the main symptom clusters of PTSD including distressing dreams (re-
experiencing cluster) and insomnia and restless sleep (hyperarousal cluster) (Krakow et al, 2001; 
Spoormaker et al, 2008).  Problems with sleep are not only thought to significantly exacerbate

daytime symptoms of PTSD but also increase the likelihood of comorbid complications such as 
depression and substance use disorders as well as suicidal behaviors (Krakow et al, 2002; 
Saladin et al, 1995; Krakow et al, 2000), a particularly critical problem in PTSD (Oquendo et al, 
2003; Sareen et al, 2005).  Moreover, because of a direct relationship between sleep disturbance 
in PTSD and suicidal ideation, it is suggested that targeting sleep disturbance may help prevent 
suicidal behaviors in PTSD (Betts et al, 2013). 
A growing body of evidence suggests that sleep disruption plays an important causal role in the 
pathogenesis of PTSD (Koren et al, 2002; Mellman et al, 2002; McLay et al, 2010; Wright et al, 
2011).  Moreover, sleep disturbance is a frequent residual complaint after successful PTSD 
treatment, a finding that applies to both psychological and pharmacological treatment 
(Spoormaker et al, 2008).  Evidence is now emerging that pharmacological targeting of sleep 
disturbance in PTSD, in which self-reported and polysomnographic improvement in sleep 
parameters is achieved, can account for over 90% of the variance in improvement in PTSD 
severity ratings and work/school function (Krystal et al, 2013). 
Understanding of PTSD pathophysiology has been greatly advanced due to heuristic models of 
trauma based on animal work on fear conditioning and extinction (Yehuda & LeDoux, 2007; 
Maren et al, 2013).  Human studies of fear memory and stress responsiveness have highlighted 
the potential role of sleep, particularly rapid eye movement (REM) sleep, in affective and 
memory processes (Pace-Schott et al, 2015; Yoo et al, 2007; Pace-Schott et al, 2009).  There is 
evidence for the hypothesis that sleep disturbances play a critical role in PTSD by compromising 
sleep-dependent affective and memory processing that may be key for recovery from PTSD 
(Yehuda & LeDoux, 2007). 
5.1. 
Sleep and PTSD 
Subjective sleep disturbance, characterized by non-restorative sleep, frequent awakenings and 
distressing dreams and nightmares related to the trauma, is a core feature of PTSD (Spoormaker 
et al, 2008).  Clinical observations focusing on the nature of sleep complaints suggest 
dysregulation in both REM and non-rapid eye movement (NREM) sleep in PTSD (Woodward et 
al, 2000; Germain et al, 2013).  Meta-analysis of polysomnography (PSG) studies in both 
military veterans and adult civilians suggest modest indices of sleep disruption in PTSD using 
these traditional measures, with greater stage 1 (light) sleep, reduced slow wave sleep (SWS), 
and greater REM density compared with individuals without PTSD (Kobayashi et al, 2007). 
Quantitative EEG, in which high frequency beta and gamma activity are considered indices of 
central arousal during sleep, has indicated both greater beta activity during NREM and lesser 
beta activity during REM sleep in PTSD, as well as disturbances in delta activity, and heart rate 
differences between REM and NREM related to the amount of REM sleep (Woodward et al, 
2002; Neylan et al, 2003; Halász et al, 2004; Woodward et al, 2000).  Such changes are 
consistent with the pathophysiology of PTSD, which involves hypervigilance and exaggerated 
responses to both external and internal stimuli, and which are putatively indicative of heightened 
nocturnal sympathetic noradrenergic activity (Berridge et al, 2012; Breslau et al, 2005; Capaldi 
et al, 2011). 
A recent evaluation of treatment algorithms for PTSD found that addressing fragmented sleep 
and nightmares consistently improves all symptom domains in PTSD, such that targeting sleep-
related symptoms has been recommended as an initial step for treatment of all patients with

TRIAL OBJECTIVES AND PURPOSE 
6.1. 
Primary Objective 
To evaluate the efficacy of TNX-102 SL (cyclobenzaprine HCl sublingual tablets) in the 
treatment of military-related PTSD. 
6.2. 
Secondary Objectives 
To evaluate the safety of TNX-102 SL (cyclobenzaprine HCl sublingual tablets) in the treatment 
of military-related PTSD. 
7. 
INVESTIGATIONAL PLAN 
7.1. 
Overall Study Design 
This is a Phase 3, 12-week, randomized, multicenter, double-blind, placebo-controlled, fixed 
dose study that will investigate the efficacy and safety of TNX-102 SL 5.6 mg (2 x 2.8 mg 
tablets) taken daily at bedtime for the management of military-related PTSD.  This study is to be 
conducted at approximately 45 investigational sites in the United States. 
The total duration of this study over 6 visits will be approximately 13-17 weeks, with 12 weeks 
of treatment duration and a variable length of screening.  This study will consist of a Screening 
visit (Visit 1, Days −35 to −8), Randomization visit (Visit 2, Day 0), telephone visit (Visit 3, 
Week 2) and three monthly in-clinic visits (Visits 4, 5 and 6 at Weeks 4, 8, and 12). 
Eligible patients who provide written informed consent to participate will have study 
assessments performed at Screening, including counseling regarding any required washout and 
instructions to refrain from use of excluded medications throughout the study. 
The length of the pre-randomization screening period is variable (7 to 35 days) in order to 
accomplish wash-out of previous medications, where appropriate, and allow for return of clinical 
laboratory results necessary to confirm eligibility.  At Visit 2, patients will return to the site for 
additional baseline assessments and randomization (Day 0), when, if they meet all study 
randomization criteria, they will be randomly assigned in a 1:1 ratio to receive placebo or TNX-
102 SL 5.6 mg.  Patients will take the study drug sublingually daily at bedtime, starting on the 
day that they are randomized and continuing for 12 weeks (or to early termination).  A dynamic 
randomization procedure will be employed at Visit 2 to minimize trial-wide imbalances between 
the treatment groups for site, sex, current tobacco/nicotine use (yes/no) and presence (yes/no) of 
current Major Depressive Episode (MDE) based on the Mini International Neuropsychiatric 
Interview, Version 7.0.2 (M.I.N.I. 7.0.2) conducted at Visit 1. 
Patients who test positive for cocaine, ecstasy (MDMA), methamphetamine or other non-
disclosed illicit drugs (other than marijuana) should be screen-failed.  In addition, patients who 
meet M.I.N.I. criteria outlined in the entry criteria for alcohol/substance use disorder over the 6 
months prior to Screening should be screen-failed. 
Patients suffering from depression are eligible for the study, provided their depression does not 
pose an undue risk to their well-being (e.g., suicidal risk) or warrant treatment with

antidepressants or other excluded treatments.  The investigator will evaluate each patient’s 
medical and psychiatric history, current symptomatology, and the results of the MINI 7.0.2, BDI-
II, C-SSRS, and CAPS-5 from Visits 1 and 2, to determine whether it is appropriate for the 
patient to participate in the study.  In addition, each patient will undergo medical monitor pre-
randomization review to ensure agreement with the investigator’s assessment.   
NOTE:  Patients who use alcohol/marijuana but do not meet criteria for alcohol/substance use 
disorder (per Diagnostic and Statistical Manual of Mental Disorders [Version 5; DSM-5]) are 
otherwise suitable for the study provided that, in the judgment of the Investigator, this usage will 
not interfere with the patient’s ability to complete the study or provide reliable data.  Information 
related to marijuana and alcohol use will be collected at Screening. 
Patients with evidence of hepatic impairment secondary to hepatitis B or C at screening, or who 
are undergoing treatment for hepatitis, should be excluded.  Patients with stable and 
asymptomatic disease whose hepatic enzymes (aspartate aminotransferase [AST] or alanine 
aminotransferase [ALT]) satisfy the study’s entry criteria (< 3 times the upper limits of normal), 
may be allowed to proceed with randomization with prior Medical Monitor approval. 
CAPS-5, M.I.N.I. 7.0.2 and Columbia Suicide Severity Rating Scale (C-SSRS) interviews will 
be conducted by an approved and qualified individual(s) at each site who has successfully 
completed training on each instrument. 
If a patient scores a 2 or 3 on the suicidal ideation section of the C-SSRS at any visit (including 
the Screening visit), the investigator and patient should work together to implement a Safety 
Planning Intervention (SPI).  As described in detail in Section 11.3.3, the recommended SPI for 
this study is the plan developed by Barbara Stanley, PhD and Gregory Brown, PhD which has 
been adopted by the U.S. Veteran’s Administration (VA) (Stanley & Brown, 2012).  The VA SPI 
is a brief clinical intervention aimed at mitigating suicide risk.  It consists of a written, prioritized 
list of coping strategies and sources of support that patients can use to alleviate a suicidal crisis.  
Sites may use an internally-developed SPI if similar in scope and purpose to the VA SPI. 
The study timeline and events schedule is provided in Appendix 1. 
7.2. 
Number of Patients and Treatment Assignment 
A total of approximately 550 patients will be randomized in a 1:1 ratio to treatment with TNX-
102 SL 5.6 mg (2 x 2.8 mg) tablets or identical SL placebo tablets.  See Section 13.2 for details 
regarding potential sample size adjustment.

7.3.5. 
Pharmacogenomic Endpoints 
In this present study, we propose to examine potential genetic determinants of treatment response 
and particular adverse events by studying the patient’s genomic profile in relation to treatment 
outcome and presence or absence of the adverse events. A single blood sample will be obtained 
at an unscheduled post-study visit, with invited participants first providing separate written, 
signed informed consent for pharmacogenomic analysis. The final list of pharmacogenomic 
endpoints will be delineated in the SAP for the pharmacogenomic portion of the study.

Efforts to Minimize Missing Data 
It is important to avoid missing data from clinical trials.  The following strategies are designed to 
minimize drop-outs and missing data in this study: 
• Providing patients with greater background on the nature of placebo-controlled 
clinical trials and explaining that completing this study, regardless of the patient’s 
level of treatment response, is essential to understanding whether TNX-102 SL may 
be helpful to others in the treatment of PTSD.  Sites will explain that the study is not 
designed to benefit the individual patient but, rather, can only provide useful 
information for future therapeutics. 
• Minimizing the burden on patients, with visits scheduled generally every 4 weeks 
(with reasonable visit window flexibility).  Clinical site personnel will also receive 
guidance regarding the special considerations necessary when dealing with patients 
with military PTSD. 
• Training of site personnel on the importance of minimizing missing data 
• Providing payment for patients’ time and effort at clinic visits, based on the duration 
of assessments and as approved by the Institutional Review Board.  Reimbursement 
for travel expenses to and from the clinic sites may also be provided to further 
minimize the financial burden of participating in the study. 
• Utilizing repeated assessments of outcome measures and analytical approaches that 
most appropriately compensate for missing data. 
8. 
SELECTION AND WITHDRAWAL OF PATIENTS 
8.1. 
Informed Consent 
A potential patient may be screened for eligibility only after the nature of the study, its purpose, 
and any other information relevant to the patient’s decision to participate have been explained to 
him or her and the patient has voluntarily confirmed his or her willingness to participate.  If 
medications are to be withdrawn for the explicit purpose of participation in this study, the patient 
must first sign an informed consent form before the withdrawal or down titration of any 
medication is initiated. 
Informed consent is documented by means of a written, signed, and dated informed consent form 
(ICF).  Separate written, signed informed consent must be obtained if the patient is to participate

Version 1.4 29Oct2019 
 
Page 38 of 87 
 
3. At Visit 2, patient is not severely depressed (based on the investigator’s judgment and 
Visit 2 C-SSRS, CAPS-5, and BDI-II, and considering the pre-randomization 
collaborative review by the investigator and medical monitor(s) of the patient’s Visit 
1 psychiatric history, presenting symptomatology, M.I.N.I. 7.0.2, C-SSRS, CAPS-5, 
and BDI-II assessments).  
4. No active suicidal intent or plan, based on Investigator’s judgment, and Visit 2 C-
SSRS responses (e.g., no C-SSRS Type 4-5 ideation or suicidal behavior since Visit 
1). 
8.5. 
Prior and Concomitant Medications 
Many concomitant medications are prohibited during this study because this study has been 
designed to evaluate the safety and efficacy of monotherapy with TNX-102 SL tablets for the 
treatment of PTSD.  The goal of the study is to recruit patients who are not currently using other 
medications to treat their PTSD, or who are not clearly benefitting from any of the medications 
that would need to be discontinued in order to enter this study.  Since many patients with PTSD 
may already be taking one or more excluded medications when screened, Principal Investigators 
should use extreme caution when determining whether a patient, in their clinical judgment, can 
be safely withdrawn from current medications that are being used to treat PTSD or are otherwise 
excluded from the protocol. 
Eligible patients will not be receiving treatment with antidepressants, antipsychotic agents, mood 
stabilizers or anticonvulsants.  In addition, eligible patients will not have taken antidepressants 
within 2 months of the Baseline visit.  This time frame is intentionally long because it is not 
considered appropriate for patients to discontinue antidepressants solely to enter the study.  An 
exception is made for the use of low-dose tricyclic agents at doses ≤ 25 mg per day, or trazodone 
at doses ≤ 150 mg per day, either of which may be discontinued for the purpose of enrollment 
but requires a 1-week medication-free period prior to randomization, as described below. 
Patients also must be willing and able to discontinue use of benzodiazepines, non-
benzodiazepines and certain other medications frequently used to treat PTSD; e.g., prazosin; 
trazodone; topiramate.  Discontinuation of any of these agents should only be considered if/when 
the patient’s clinical condition and stability will not be adversely affected. 
Unless otherwise stated, excluded medications (e.g., trazodone, prazosin, topiramate, alpha- 
adrenergic agonists or antagonists [e.g., prazosin; tamsulosin; terazosin; doxazosin, silodosin, 
alfuzosin, clonidine, guanfacine], buspirone, benzodiazepines, and non-benzodiazepine 
hypnotics [zolpidem, zaleplon, eszopiclone]) will require a 1-week drug-free period prior to the 
Baseline visit (Visit 2).  Similarly, all opioid medications, including tramadol and tapentadol, are 
excluded medications.  Patients on chronic opioids are not appropriate candidates for 
participation, but there may be patients with occasional PRN opioid usage or who were recently 
on a short course for acute pain who may be appropriate if, in the clinical judgement of the 
Investigator, they could be safely tapered and remain opioid free for the week before baseline 
visit and throughout the 12 weeks of the study.  The screening period of up to 35 days is 
provided to ensure a safe tapering rate and discontinuation of excluded medications, per 
Investigator’s discretion, leading up to the 1-week medication-free period required before the 
randomization/baseline visit.

Version 1.4 29Oct2019 
 
Page 39 of 87 
 
Other medications capable of modifying the pharmacologic activity of TNX-102 SL (e.g., α-
adrenergic agonists/antagonists; potent CYP3A4 inhibitors) will also be excluded, and 
discontinuing these medications should only be considered if clinically acceptable.  A list of 
CYP3A4 inhibitors is provided in 0; only those considered potent or strong inhibitors (in the left-
hand column) are excluded medications.   
8.5.1. 
Allowed Concomitant Medications 
It is ideal to have all patients participating in the study go without any hypnotic agents for the 
entire double-blind period of the study.  Yet there may be instances in which patients’ insomnia 
symptoms need to be addressed with a concomitant treatment.  In these instances, the 
Investigator should recommend use of an antihistamine-based OTC hypnotic, such as Benadryl® 
or generic diphenhydramine 25-50 mg, for a limited period (e.g. no more than a few nights in a 
row).  Patients should be asked to keep track of their use of such sleeping remedies, and again, 
chronic nightly use should be avoided whenever possible.   
Melatonin is considered an allowable concomitant medication but its usage should have been 
stable for at least 30 days prior to baseline and usage should remain stable during the study.  If 
diphenhydramine is ineffective, the treating Investigator should contact the medical monitor to 
discuss alternative options.    
Allergy medications and cold remedies containing adrenergic agonist decongestants such as 
pseudoephedrine or phenylephrine should be avoided unless absolutely necessary (and in such 
cases when considered absolutely necessary, they should be avoided in the evening or at bedtime 
to minimize their interference with sleep).  Sympathomimetics such as adrenergic agonist 
decongestants have the potential to acutely worsen PTSD symptoms and therefore could 
confound the assessment of TNX-102 SL versus placebo for treatment of PTSD. 
Other prescription or over-the-counter medications not specifically excluded by entry criteria 
typically may be continued during the study, with the expectation that chronic medications 
should have been used in a stable fashion for at least 30 days prior to randomization.  Sites 
should contact the medical monitor for any questions about whether a concomitant medication 
may be continued during the study or if it would be acceptable to taper an excluded medication. 
8.6. 
Withdrawal Criteria 
In accordance with the Declaration of Helsinki, human patients have the right to withdraw from 
the study at any time for any reason.  The investigator and Tonix also have the right to remove 
patients from the study.  Additional information regarding withdrawal or discontinuation of 
patients is described in detail in Section 10.5.1. 
9. 
STUDY DRUG MATERIALS AND MANAGEMENT 
9.1. 
Study Drug Packaging, and Labeling and Storage 
Study drug supplies will be packaged identically so as to maintain the integrity of the study 
blind.  The study medication bottles will be labeled minimally with the following information:  
study number TNX-CY-P301, sponsor name and address, bottle number, quantity, storage 

Protocol No TNX-CY-P301 
 
CONFIDENTIAL 
 
 
Version 1.4 29Oct2019 
 
Page 40 of 87 
 
conditions, usage instructions, and caution statements for investigational new drug, i.e., Caution: 
New Drug Limited by United States Law to Investigational Use, and Keep Out of Reach of 
Children and Pets. 
Each study medication bottle will contain 40 tablets.  Two bottles will be dispensed to each 
patient at Visit 2 (baseline), Visit 4 (Week 4) and Visit 5 (Week 8); this will provide the patient 
with 80 tablets to cover the 4 weeks of dosing between visits, plus additional tablets to cover loss 
and/or visit window variability.  The patient should be instructed to take all the tablets in one 
bottle before opening the second bottle.  The patient should be instructed to keep this study 
medication in a safe location out of extreme environmental conditions and out of the reach of 
children and pets, and be instructed that this medication is not to be taken by any individual other 
than the study patient.  Each patient will also be instructed that they will be expected to return 
both bottles and all unused study medication at each clinic visit; unused medication will be 
counted to assess compliance with study drug treatment. 
Storage of the study drug at the investigational site should be under locked and secure conditions 
with limited staff access.  Study drug should be stored at 20-25°C/68-77°F in a 
temperature/humidity-monitored room; however, brief excursions (15-30°C/59-86°F) as defined 
in the Study Reference Manual (IP Receipt and Storage) are permitted without the sponsor’s 
approval. 
9.2. 
Dosing Instructions 
Patients will be instructed to take two tablets of their assigned study drug (TNX-102 SL 2.8 mg 
tablets or placebo tablets) sublingually, placed simultaneously under the tongue, each evening 
at bedtime starting at bedtime on evening of Day 0 (Day of Visit 2) and continuing without 
interruption for 12 weeks.  The study drug should be taken at bedtime after teeth brushing and 
other oral care has been completed.  The mouth/sublingual area should be moist at the time of 
dosing, so the patient should drink a few sips of water prior to dosing, especially if prone to dry 
mouth.  Patients will be instructed to place the two SL tablets under their tongue and keep them 
there until they have dissolved.  They should not swallow, crush or chew the tablets.  Patients 
should not eat or drink (or chew gum) for at least 15 minutes after dosing, and preferably not 
until morning.  Patients will be reminded that only 2 (two) tablets are allowed per day. Note:  In 
the event that the patient misses a dose, instruct the patient to continue dosing with two (2) 
tablets the next evening; i.e., they should not take more to make up for the missed dose. 
9.3. 
Dispensing Instructions 
Each patient who has met the randomization criteria (Section 8.3) will be assigned 2 double-
blind treatment bottles at Visit 2 via the IWRS, with a unique, but otherwise random bottle 
number that is generated when the study coordinator successfully completes randomization 
procedures.  Patients will also be assigned two new treatment bottles at Visits 4 and 5 via the 
IWRS.  The bottle numbers provided by the Interactive Web Response (IWR) system at these 
visits will tell the site which treatment bottles have been assigned to the patient. 
In the event of loss of study medication, new medication will be provided by the IWR system, 
when appropriately requested by the site and/or the sponsor or designee. 
Study treatments for the double-blind treatment phase are either:

Treatment A: 2 × TNX-102 SL 2.8 mg tablets (“TNX-102 SL”) to be taken sublingually 
once daily at bedtime. 
Treatment B: 2 × placebo tablets (“placebo”) to be taken sublingually once daily at bedtime. 
9.4. 
Release of Clinical Study Supplies to the Investigator 
Tonix or Tonix’s designee’s standard operating procedures for releasing clinical trial supplies to 
the site will be followed. 
9.5. 
Study Drug Accountability and Reconciliation 
All patients will be expected to bring their bottles of study medication with them to all study 
visits.  At each study visit, the site staff will inspect the medication bottles, and perform a count 
of the tablets remaining in the bottles and document this in the patient’s record.  An assessment 
of medication adherence should be done by the study staff to ensure that the patient understands 
all dosing instructions and is taking the medication as prescribed.  Patients will be asked for an 
explanation if the count of returned study drug tablets indicates a discrepancy between the 
expected number of tablets dosed and the number returned in the bottles.  If it is found that the 
patient is not taking the study medication as expected, the patient will be re-counseled with 
instructions, and this should be noted in the patients’ records.  A deviation should be recorded on 
any patient who is less than 70% compliant with dosing between visits. 
If the patient fails to return any of the unused study drug as expected, the patient should be 
questioned regarding the reason for the lower than expected tablet number and about potential 
misuse, abuse or diversion.  If more than 8 tablets cannot be accounted for at any of the visits 
where drug is returned (week 4, 8 or 12), the investigator will be asked to evaluate the situation, 
and a written summary of this evaluation should be added to the source and entered onto the case 
report form (CRF).  Situations where replacement drug is requested, or when more than 8 tablets 
cannot be accounted for, should be recorded as deviations.   
All study medication, including partial and empty bottles, must be maintained at the study site 
until Tonix or its designee verifies drug accountability and provides instruction for destruction or 
the return of the investigational product to the Sponsor’s drug distribution depot. 
Tonix or their designee will perform drug accountability which entails reconciliation between the 
amount of drug shipped to the study site, study drug assigned and dispensed to the patient 
(including returned unused assigned study drug), and study supplies that were never dispensed 
and/or assigned to patients.

STUDY VISITS AND PROCEDURES 
The overall and detailed schedule for study procedures and visits is provided in Appendix 1. 
10.1. 
Visit 1 (Screening: Day -35 to -7) 
10.1.1. 
Informed Consent 
Before the potential patient has undergone any study-related screening procedures, including any 
downward titration or withdrawal of medications, the nature of the study and the potential risks 
associated with it will be explained to the patient, and the patient will be given an opportunity to 
ask questions to his or her satisfaction.  After all questions are answered, but before proceeding 
further, the patient must read and sign a written informed consent form.  This signed informed 
consent form will be retained in the Investigator’s study file, and the date the patient signed the 
form will be entered into the Case Report Form (CRF).  The patient will be provided with a copy 
of his or her signed and dated informed consent form.  The patient will be required to sign all 
updated informed consents. Separate written, signed informed consent must be obtained if the 
patient is to participate in the post-study pharmacogenomic assessment. 
10.1.2. 
Screening Overview 
Screening Visit 1 will start a variable length screening period.  The length of the screening 
period is to be no shorter than 7 days, but may be as long as 35 days in order to accommodate 
medication taper and discontinuation or other study requirements. 
If the patient is eligible to continue in the study, and does not need to discontinue any excluded 
medication, the patient may be scheduled to return for Visit 2 (Randomization) in 7 (or more) 
days, assuming all screening evaluations have been completed, including confirmation of 
acceptable laboratory and ECG results.  If the patient needs to undergo taper and discontinuation 
of excluded medication, the Investigator will generate a written down titration schedule for the 
patient and will schedule Visit 2 such that the date of Visit 2 is at least 1 week after the date of 
the final dose of any excluded medication.  If additional clinic visits are deemed necessary by the 
investigator for clinical monitoring of the patient before scheduling Visit 2, such visits will be 
recorded as unscheduled visits. 
10.1.3. 
Patient Numbering 
All screened patients will be assigned a unique concatenated 6-digit site-patient number (e.g., 
102-112) by the IWR system.  A screening log or system documenting the following information 
will be recorded and maintained, and will include the patient’s initials, screening number, 
whether the patient was ultimately randomized or not, and if not randomized, the reason the 
patient was excluded/screen-failed. 
10.1.4. 
Screening and Assessments/Procedures 
The following screening assessments/procedures will be completed in the following general 
order:

• Review inclusion/exclusion criteria 
Only those patients meeting all of the inclusion and none of the exclusion criteria will be eligible 
to continue.  NOTE:  Final determination of eligibility based on clinical laboratory tests will be 
made when results have been returned. 
Sites will be asked to complete and submit to the Tonix medical monitoring team key screening 
information.  This information will be reviewed by the Tonix medical monitoring team to help 
ensure the selection of well-qualified patients.  The specific requirements and timelines 
associated with this pre-randomization review process will be outlined in a separate document. 
Once eligibility has been confirmed and authorization for randomization granted by a Tonix 
medical monitor, eligible patients will return to the clinic for Visit 2. 
There is no requirement for Follow-Up visits for patients who are screen failures.  Patients who 
fail to qualify should have their medication adjusted, as appropriate, per the judgment of the

Investigator and be released from the clinic.  There will be no requirement to enter data into the 
electronic case report form (eCRF) for patients who are not randomized. 
10.2. 
Visit 2 (Baseline: Day 0) 
Visit 2 should be scheduled 7 to 35 days after Visit 1.  Study procedures will be completed 
(including qualifying baseline assessments for the C-SSRS and CAPS-5).  If the patient meets all 
randomization criteria, the patient will be randomized via the IWR system to receive double-
blind study medication. 
10.2.1. 
Pre-Randomization Assessments 
The following assessments must be completed at Visit 2 to confirm that the patient is eligible for 
randomization.  Upon arrival at the clinic, the following assessments should be done, preferably 
in this order: 
• Assess occurrence of adverse events 
• Update medical history (with changes since screening noted) 
• Assess changes in medication history and concomitant medications 
• Obtain vital signs and weight 
• Administer CAPS-5 - “Symptom Severity Version”, using 1-week recall 
• Conduct urine drug screen (urine dipstick, only as necessary, if select Visit 1 tests were 
positive for excluded medications that required discontinuation prior to randomization) 
• Conduct urine pregnancy test (for women of child-bearing potential)  
• Perform visual examination of the oral cavity  
• Have the patient complete the following outcome scales (in order): 
o SDS 
o PROMIS scale for sleep disturbance 
o MTRSS (assessment of sedation) 
o CSFQ-14 
o BDI-II (needs to be completed prior to the C-SSRS and reviewed by the C-SSRS 
rater at outset of C-SSRS interview) 
• Administer the C-SSRS- Since Last Visit Version (with rater review of BDI-II prior to 
starting C-SSRS interview) 
10.2.2. 
Randomization Criteria 
Once all pre-randomization assessments have been completed, only those patients who meet all 
of the following randomization criteria will be eligible to continue: 
1. Patient continues to meet all inclusion and exclusion criteria, including urine and blood 
test results, and 

Protocol No TNX-CY-P301 
 
CONFIDENTIAL 
 
 
Version 1.4 29Oct2019 
 
Page 45 of 87 
 
2. Visit 2 total CAPS-5 score ≥ 33 (“Symptom Severity” version using 1-week recall), and 
3. At Visit 2, patient is not severely depressed (based on the investigator’s judgment and 
Visit 2 C-SSRS, CAPS-5, and BDI-II, and considering the pre-randomization 
collaborative review by the investigator and medical monitor(s) of the patient’s Visit 1 
psychiatric history, presenting symptomatology, M.I.N.I. 7.0.2, C-SSRS, CAPS-5, and 
BDI-II assessments).  
4. No active suicidal intent or plan, based on Investigator’s judgment, and Visit 2 C-SSRS 
responses (e.g., no C-SSRS Type 4-5 ideation or suicidal behavior since Visit 1). 
If the patient does not satisfy these randomization criteria, the patient has failed to qualify for 
this study and should be considered a screen failure, with the reason documented.  With Medical 
Monitor approval, if the patient is otherwise considered a qualified and compliant patient, Visit 2 
may be delayed to accommodate situations in which extenuating or short-term circumstances do 
not warrant screen failure. 
If the patient does satisfy these randomization criteria, then continue with the following: 
• Randomize the patient via IWRS Randomization System 
• Dispense 4-week supply (two bottles) of double-blind study medication 
• Review patient instructions regarding study drug dosing (Section 9.2) 
• Schedule next study visit 
10.3. 
Visit 3 (Telephone Visit: Day 14) 
Visit 3 will be done as a telephone call to the patient and should be conducted after 2 weeks of 
treatment, on Day 14 ± 3 days. 
The following steps should be completed: 
• Assess changes in concomitant medications 
• Assess study drug compliance based on patient verbal report 
• Assess occurrence of adverse events, including any oral adverse events and whether an 
unscheduled visit is indicated for an examination of the oral cavity 
• Review patient instructions regarding drug dosing.  
• Administer the ‘Since Last Visit’ C-SSRS 
After all of the items have been reviewed with the patient, the patient should be given an 
appointment to return to the clinic for Visit 4, and be re-instructed, as necessary, on dosing 
instructions, and reminded to bring study medication back to the clinic at their next visit. 
10.4. 
Visit 4 and 5 (Weeks 4 through 8) 
Visits 4 and 5 are similar study visits that are scheduled to be conducted after 4 and 8 weeks of 
treatment, respectively.  Visit 4 should occur on Day 28 ± 5 days and Visit 5 should occur on 
Day 56 ± 5 days.

Early Termination (ET) 
In accordance with the Declaration of Helsinki, patients have the right to withdraw from the 
study at any time for any reason, and they will be advised of this right.  The investigator and 
Tonix also have the right to remove patients from the study.  Specific reasons for removal of a 
patient from the study could include, but are not limited to: 
• 
An adverse event (AE) 
• 
An illness that, in the judgment of the investigator or Tonix, might invalidate the study 
results or place the patient at risk 
• 
The request of the patient, investigator, or Tonix, whether for administrative or other 
reasons 
• 
Pregnancy 
This study will attempt to obtain as complete information as possible on all participating 
patients.  An effort must be made to contact the medical monitor prior to any patient’s early 
termination.  Each reason for early termination will be adjudicated.  Patients who wish to 
terminate their participation in the study should be instructed to come to the clinic for an Early 
Termination Visit.  The purpose of the Early Termination visit is to obtain critical information 
about the patient’s participation, and should be scheduled preferably before there has been a 
substantial lapse in study medication usage.  However, even if there has been a medication lapse, 
the patient should be encouraged to return to the clinic for this visit, and should be instructed to 
return all study medication.  NOTE:  These visit procedures are not intended for patients who fail 
to qualify for randomization or for any other reason withdraw from the study prior to receipt of a 
dose of double-blind study drug.

Once these assessments have been completed, the patient may be discharged from the study, 
provided that there is no need for additional follow-up to continue to monitor an adverse event or 
other condition.  
10.5.2. 
Unscheduled Visits 
Patients may need to be seen at other times than the scheduled study visits for additional safety 
assessments or to follow-up, as medically necessary, on clinical laboratory results, physical 
examination, or other findings.  If an additional study visit is warranted, or occurs, the date and 
nature of the visit will be documented in the CRF and in the source documents. 
Patients who call to report an oral AE that is a lesion of some form should be brought back to the 
clinic for an unscheduled oral exam if deemed appropriate. In the case in which the AE is solely 
sensory in nature (such as oral hypoaesthesia) and the patient reports there is no discernable 
associated lesion, an unscheduled oral exam is not required but may be arranged if the 
investigator determines it to be clinically appropriate. 
 
10.6. 
Pharmacogenomic Assessment (Post-Study) 
For patients who participated in P301 and are invited back to the site for participation in the 
optional pharmacogenomics assessment after having finished their participation, the patients will 
be invited in for an unscheduled visit in which they first will learn about the pharmacogenomics 
study and sign a separate written pharmacogenomics informed consent form. Next, a blood 
sample is drawn and processed for pharmacogenomic analysis. Once completed, the patient is 
discharged from the pharmacogenomics portion of the study.

STUDY ASSESSMENTS 
11.1. 
Screening Assessments 
11.1.1. 
Psychiatric and Medical History 
A psychiatric interview using the Mini International Neuropsychiatric Interview (M.I.N.I.-
Version 7.0.2) and a comprehensive medical history will be obtained at screening in order to 
determine whether the patient is eligible for enrollment. 
While patients with mild traumatic brain injury (TBI) are eligible to participate in the study, 
moderate and severe TBI are excluded.  Mild TBI (or concussion) is one of the most common 
forms of combat-related injury.  Based on self-report data, approximately 15% of troops engaged 
in active combat in Afghanistan and Iraq may have suffered a mild TBI (Hoge et al., 2008).  A 
history of TBI is defined as any traumatically induced structural injury and/or physiological 
disruption of brain function as a result of an external force that is indicated by new onset or 
worsening of at least one of the following clinical signs, immediately following the event: 
1. Any period of loss of or a decreased level of consciousness; 
2. Any loss of memory for events immediately before or after the injury; 
3. Any alteration in mental state at the time of the injury (e.g., confusion, disorientation, 
slowed thinking); 
4. Neurological deficits (e.g., weakness, balance disturbance, praxis, paresis/plegia, change 
in vision, other sensory alterations, aphasia) that may or may not be transient;  
5. Intracranial lesion. 
Although severity of TBI depends in part on patient assessment in the days after a traumatic head 
injury, for the purposes of this protocol, mild TBI is defined as: 
1. Normal structural brain imaging findings 
2. Loss of consciousness not greater than 30 minutes after injury 
3. Alteration of consciousness not greater than 24 hours after injury 
4. Posttraumatic amnesia not more than 24 hours after injury 
5. No ongoing neurological deficits (Note: tinnitus, headaches, or sleep disturbances that 
appeared to result from the head trauma would not be considered as ongoing neurological 
deficits and therefore should not be interpreted as meaning the person has a greater 
severity than mild TBI.) 
In addition, the past medication history will be reviewed.  Any psychiatric medication or PTSD 
therapies utilized during the patient’s lifetime should be collected.  Responses from the M.I.N.I. 
will serve to document the presence of other psychiatric conditions.  The diagnosis and severity 
of PTSD will be based on the CAPS-5 (Section 11.2.1). 
11.2. 
Efficacy Assessments 
The primary efficacy endpoint and many of the secondary and exploratory efficacy endpoints in 
this study are derived from clinician-administered assessments which must be administered by 
qualified and trained individuals at each clinical site.  Study specific training will be required 
before staff is allowed to administer these scales.  In an attempt to minimize variability in 

Protocol No TNX-CY-P301 
 
CONFIDENTIAL 
 
 
Version 1.4 29Oct2019 
 
Page 51 of 87 
 
responses of a given patient over time, it is important that the same rater administer the scales to 
a given patient throughout the study unless absolutely unavoidable due to the rater’s absence 
from the clinic.  It is also important that the assessments, including those that are patient-
completed, be conducted in the specified order, according to specific instructions, and in a 
setting where the patient has minimal distractions, appropriate privacy and sufficient time to 
complete them. 
11.2.1. 
Clinician-Administered PTSD Scale (CAPS-5) 
The primary efficacy endpoint is the change from baseline (Visit 2) in total CAPS-5 score at 
Week 12 (Visit 6). 
The CAPS-5 is an updated and validated version of a semi-structured interview that has been 
designed to assess the essential features of PTSD as defined by the DSM-5 (Weathers et al, 
2013).  The CAPS-5 affords the clinician flexibility to inquire about symptoms and diagnostic 
status over different time frames, such as past week, past month, and/or worst month for lifetime.  
For this study, a “Diagnostic” version of the CAPS-5 (lifetime and past month recall) will be 
utilized at the Screening visit to confirm the diagnosis of PTSD and determine eligibility based 
on symptom severity.  A “Symptom Severity” version of the CAPS-5 (past week recall) will be 
completed by clinician at all other time points (Baseline [Visit 2] and after 4, 8, and 12 weeks of 
treatment [Visits 4, 5, and 6]).  A CAPS-5 total score of 33 or above at both Screening 
(“Diagnostic” version) and Baseline (“Symptom Severity” version) is requisite for eligibility. 
In addition to the total symptom score, the CAPS-5 affords the opportunity to examine clusters 
of symptoms, including Criterion B (intrusion symptoms), Criterion C (persistent avoidance), 
Criterion D (negative cognitions and mood), and Criterion E (arousal and reactivity), all of which 
will be secondary efficacy endpoints. 
The CAPS-5 interview contains the following components: 
• 
Life Events Checklist for DSM-5 (LEC-5):  Completed by the patient at Screening Visit 1 
only) and reviewed by the rater of the CAPS-5 interview at the start of the interview. 
• 
PTSD Symptoms 
o Criterion A: the rater will review the patient-completed LEC-5 and then inquire into 
the qualifying index trauma (Criterion A) utilizing the study-specific Criterion A - 
Assessment Form (CA-AF) (Visit 1 only) 
o Criterion B: Items 1-5 
o Criterion C: Items 6-7 
o Criterion D: Items 8-14 
o Criterion E:  Items 15-20 
o Criterion F: Items 21-22 
o Criterion G: Items 23-25 
o Global ratings: Items 26-28 
o Dissociative symptoms: Items 29-30

Version 1.4 29Oct2019 
 
Page 52 of 87 
 
Further instruction on when to complete each component will be provided in the study specific 
versions of the CAPS-5 forms. 
The LEC-5, which documents the patient’s lifetime traumatic experiences, will be completed by 
the patient at Screening Visit 1 before the clinician administered CAPS-5.  The CAPS-5 rater 
will be responsible for reviewing the answers on this form with the patient as part of the 
completion of the CAPS-5 Criterion A - Assessment Form in order to determine if the traumatic 
experience qualifies the patient for inclusion in the study.  NOTE:  If worst month lifetime PTSD 
symptoms resulted from earlier trauma(s), such as trauma(s) before age 18 or trauma(s) not 
related to military services, the prospective patient should be excluded from participation. 
At Screening, the total CAPS-5 score (Diagnostic version with 1-month recall) must be ≥ 33 and 
must meet the other diagnostic criteria specified in Inclusion Criterion 2 (Section 8.2) in order 
for the patient to continue.  At Baseline (Visit 2), the total CAPS-5 score (past week recall) must 
again be ≥ 33. 
The CAPS-5 interview must be completed by a qualified and trained rater.  This rater should be 
kept consistent for a given patient throughout the study.  If circumstances require non-conformity 
with the single rater approach for any patient, this should be documented.  Additional 
information regarding the conduct, rating, and scoring of the CAPS-5 instrument as well as the 
requirements for rater training will be provided separately. 
11.2.2. 
Beck Depression Inventory (BDI-II) 
The Beck Depression Inventory (BDI-II) is a 21-item measure of the severity of current 
depressive symptoms, extensively validated for use in both medical and mental health 
populations.  While this instrument does not provide a psychiatric diagnosis of depression and 
has considerable overlap with PTSD associated symptoms (Resick et al, 2017), it does provide a 
continuous scale for measuring changes in the severity of symptomatology.   
The patient will be asked to complete this questionnaire at all in-clinic study visits.  At Visit 1 
and Visit 2, patients whose responses are indicative of suicidal ideation, as defined by a response 
to Item #9 of ≥1 should be carefully evaluated and compared to the patient’s C-SSRS responses, 
and appropriate intervention prescribed, if indicated.  In addition, patients’ BDI-II responses at 
Screening and Baseline (Visits 1 and 2) should be reviewed by the investigator as part of the 
comprehensive evaluation of the patient’s psychiatric status and overall eligibility, since patients 
suffering from severe depression should be screen failed and referred for appropriate 
psychological evaluation or care, as necessary.  After Visit 1, the responses to Item #9 should be 
monitored along with C-SSRS responses to ensure that there is no increase in suicidal ideation 
during the study, and the total score should also be monitored to ensure the patient’s 
psychological status remains stable. 
11.2.3. 
Clinical Global Impression of Improvement (CGI-I) 
The CGI-I will be completed by an Investigator to evaluate the patient’s status since initiation of 
treatment.  The CGI-I, status since initiation of treatment, is the first key secondary efficacy 
endpoint in this study.  The CGI-I should be completed toward the end of each in-clinic post-
Baseline study visit once all of the assessments are available for the investigator’s review.

11.2.3.1. CGI-I Assessments at Weeks 4, 8, and 12 
Once the patient has been randomized, an Investigator will complete the CGI-I assessment after 
4, 8, and 12 weeks of treatment (Visits 4 -6) in order to assess the overall change in the patient’s 
status since Baseline and answer the following question: 
Since the initiation of treatment at Visit 2, the patient is: 
1 = Very much improved 
2 = Much improved 
3 = Minimally improved 
4 = No change 
5 = Minimally worse 
6 = Much worse 
7 = Very much worse 
11.2.4. 
Patient Global Impression of Change (PGIC) 
The PGIC is a validated, self-report instrument to gauge the patient’s assessment of change in 
condition.  This form will be completed by the patient after 4, 8 and 12 weeks of treatment 
(Visits 4, 5 and 6, respectively).  The patient will answer a single question: 
Since the initiation of study medication, overall, my PTSD symptoms are: 
1 = Very much improved 
2 = Much improved 
3 = Minimally improved 
4 = No change 
5 = Minimally worse 
6 = Much worse 
7 = Very much worse 
11.2.5. 
PROMIS Sleep (short form) Scale 
PROMIS refers to the Patient-Reported Outcome Measurement Information System 
(www.nihpromis.org), an NIH-funded initiative to develop instruments to be used across chronic 
conditions. 
The PROMIS Sleep scale (short form 8a) will be assessed at Baseline (Visit 2) and after 4, 8, and 
12 weeks of treatment (Visits 4, 5, and 6, respectively). 
11.2.6. 
Sheehan Disability Scale (SDS) 
The SDS scale is a self-report questionnaire that was designed to assess the patient’s view of the 
degree to which symptoms have disrupted work, social life/ leisure activities, and family life/ 
home responsibilities during the past 1 week (Sheehan & Sheehan, 2008).  In addition, the SDS 
asks the patient to provide the number of days or work lost as well as unproductive days in the 
past week.  The SDS scale will be completed by the patient at Baseline (Visit 2), and after 4, 8, 
and 12 weeks of treatment (Visits 4, 5, and 6, respectively).

11.3. 
Safety Parameters 
Safety will be assessed by evaluation of adverse events, responses on the C-SSRS and BDI-II, 
clinical laboratory tests, vital signs, weight, patient ratings of sexual function assessed by the 
CSFQ-14, and patient-rated assessments of morning sedation as assessed by the MTRSS. 
11.3.1. 
Adverse Events (AEs) 
Patients will be monitored for AEs throughout the study from the time that the patient signs an 
informed consent and onward.  AEs that are spontaneously reported, elicited or observed are to 
be recorded on the CRF with the date, time of onset, date and time of resolution, severity, 
seriousness, causality (relationship to study medication), actions required, and outcome. 
To elicit AEs, non-leading, simple questions with minimal connotations should be used as the 
initial questions at all evaluation points during the study.  Examples of these questions can be: 
• 
How have you felt since your last visit? 
• 
Have you had any health problems since your last visit? 
If an AE occurs, the investigator will institute support and/or treatment as deemed appropriate.  
If a non-serious AE is unresolved on the last day of the study, an effort should be made to follow 
up until the AE is resolved or stabilized, the patient is lost to follow-up, or there is some other 
resolution of the event. 
There are many symptoms associated with PTSD that can vary in intensity and frequency over 
time.  Only symptoms that significantly worsen or become more frequent, in the opinion of the 
patient and outside of their normal experience, should be reported as an adverse event. 
If a patient reports an oral cavity adverse event, the Investigator should examine the oral cavity 
to confirm the presence or absence of any irritation or other signs.  Additional details related to 
onset, duration, severity and reversibility of the oral cavity event will be documented 
(Section 11.3.5). 
Additional information regarding definition and reporting requirements for adverse events, 
serious adverse events, and pregnancies is provided in Section 11.3.1. 
11.3.2. 
Columbia-Suicide Severity Rating Scale (C-SSRS) 
The C-SSRS is a questionnaire developed by researchers at Columbia University to assess 
suicide risk and to track suicidal ideation and behavior during clinical trials.  This scale is 
intended to be used by individuals who have received training in its administration.  The 
questions contained in the Columbia-Suicide Severity Rating Scale are suggested probes.  
Ultimately, the determination of the presence of suicidal ideation or behavior depends on the 
judgment of the individual administering the scale. 
There are multiple versions of this questionnaire.  At Visit 1, the “baseline/screening” 
questionnaire will be administered and the recall periods will be “lifetime” and “within the past 6 
months” for suicidal ideation, and “within the past year” for suicidal behaviors.  Patients whose 
responses are indicative of suicidal ideation with intent and/or plan (e.g., Type 4-5 ideation) 
within the past 6 months or a history of prior suicidal behavior within the past year will be

At all subsequent visits (Visit 2 through 6), the “since last visit” questionnaire will be 
administered, and the recall period on this will be “since the last visit”.  Note that if there has 
been a significant change in responses indicative of increased suicide risk, appropriate 
intervention should be prescribed as described below. 
11.3.3. 
Safety Planning Intervention (SPI) 
The C-SSRS is completed at every visit in order to assess for changes in suicidality during the 
study.  As a screening and baseline entrance criterion, patients exhibiting Type 4 or 5 ideation in 
the past 6 months or a history of suicidal behavior in the past 12 months are not eligible for the 
study due to this risk and should be referred for appropriate emergency care.  If a patient scores a 
4 or 5 at a clinic visit following randomization, the patient should be withdrawn from the study 
and referred for appropriate emergency care.  If a patient scores a 4 or 5 at any clinic visit, it 
should be reported as a serious adverse event. 
If a patient scores a 2 or 3 on the suicidal ideation section of the C-SSRS at any visit (including 
the Screening visit), the investigator and patient should work together to implement a Safety 
Planning Intervention (SPI).  In addition, if a post-baseline score of 2 or 3 represents a significant 
change from the patient’s baseline status, it should be recorded as an adverse event. The 
recommended SPI for this study is the plan developed by Barbara Stanley, PhD and Gregory 
Brown, PhD which has been adopted by the U.S. Veteran’s Administration (VA) (Stanley & 
Brown, 2012).  The VA SPI is a brief clinical intervention aimed at mitigating suicide risk.  It 
consists of a written, prioritized list of coping strategies and sources of support that patients can 
use to alleviate a suicidal crisis.  Sites may use an internally-developed SPI if similar in scope 
and purpose to the VA SPI.  Additional information and training on the implementation of an 
SPI will be provided prior to initiation of the study. 
11.3.4. 
Physical Examination 
A complete physical examination will be performed at Screening Visit 1 only.  At a minimum, 
the physical examination will include the following components: HEENT (head, eyes, ears, nose, 
and throat), neck, chest and lungs, cardiovascular, abdomen, skin, and musculoskeletal.  The 
physical examination may exclude rectal, genitourinary, and breast examinations. 
11.3.5. 
Visual Examination of Oral Cavity 
A visual examination of the oral cavity should be done at Screening (Visit 1), Baseline (Visit 2) 
and after 12 weeks (Visit 6) of treatment and/or at Early Termination.  In addition to these 
regularly scheduled examinations, a visual inspection of the oral cavity (including the sublingual 
area) should be done any time a patient spontaneously reports an oral adverse event (other than 
transient sensory AEs such as tongue numbness, tingling or bitter taste) to confirm presence or 
absence of any irritation or other signs.  Additional details related to onset, duration, severity and 
reversibility of oral events will be documented in the CRF. 
11.3.6. 
Vital Signs, Height and Weight 
Vital signs (sitting blood pressure and heart rate, respiratory rate, oral temperature, and weight) 
will be assessed at Screening (Visit 1), Baseline (Visit 2) and after 4, 8, and 12 weeks of 
treatment (Visits 4, 5, and 6/Early Termination).  Height will be measured without shoes at Visit 

Protocol No TNX-CY-P301

1 only.  The BMI will be a derived variable, based on height and weight entries.  A BMI > 45 is 
an exclusion criterion. 
11.3.7. 
Electrocardiogram (ECG) 
A 12-lead ECG will be performed at Screening (Visit 1) and will be reviewed by the Investigator 
for the purpose of excluding from participation patients who have either a history of or current 
evidence of clinically significant cardiac disease (e.g., significant arrhythmias or heart block, 
heart failure, or myocardial infarction within the past 2 years) or a QTcF at Screening >450m/sec 
(males) or QTcF >470m/sec (females). 
The ECG interpretation by the Investigator will be recorded in the CRF as normal, abnormal but 
clinically insignificant, or abnormal and clinically significant.  In addition, the standard ECG 
parameters including rhythm, heart rate, and intervals for PR (or PQ), QRS, and QTcF 
(Fridericia’s) corrections for heart rate will be recorded. 
If the Investigator has any concerns about the eligibility of a patient or wishes to confirm his/her 
assessment, the Investigator should consult with the medical monitor for this study. 
11.3.8. 
Clinical Laboratory Assessments 
The clinical laboratory evaluations to be performed in this trial are listed in Table 2.  Those 
marked as screening tests will be performed at screening only.  All other tests will be performed 
at Screening (Visit 1) and after 12 weeks of treatment (Visit 6), or Early Termination.  Clinical 
laboratory values may be repeated prior to randomization in order to confirm exclusionary levels 
for TSH, ALT and/or AST values.  If these values remain persistently elevated upon repeat, the 
patient is not eligible for randomization. 
With the exception of the urine pregnancy tests or the ad hoc urine drug test required at baseline 
for patients washing off excluded medications (e.g., opioids, benzodiazepines, amphetamines), 
all clinical laboratory evaluations will be analyzed via a central clinical laboratory, and 
information regarding appropriate sample volume, collection tubes, sample labeling and 
handling, and shipment will be provided in a study manual. 
A urine drug screen for drugs of abuse (including marijuana) will be collected at Screening 
Visit 1 and sent to the central laboratory for analysis.  If the patient has a positive drug screen at 
Visit 1 and/or Visit 2 for anything other than marijuana, and the results cannot be explained by 
use of current allowable prescription medications, the patient should be excluded from the study.  
If the urine drug screen is positive at Visit 1 and the results can be explained by the use of 
current prescription medications (e.g., opioids, benzodiazepines, amphetamines) that will be 
discontinued during screening, the investigator must repeat the drug screen and obtain a negative 
result using an in-clinic urine dipstick drug screen prior to randomization to confirm eligibility 
for the study. 
Each clinically significant abnormal laboratory value or other clinically meaningful abnormality 
should be followed until the abnormality resolves or until a decision is made that it is not likely 
to resolve.  If such abnormalities do not return to normal within a reasonable period, their 
etiology should be identified and Tonix or designee should be notified.  Treatment-emergent 
clinically significant abnormalities in laboratory values will be recorded as AEs.

11.3.9. 
Assessment of Changes in Sexual Function: Changes in Sexual Functioning 
Questionnaire Short-Form (CSFQ-14) 
The Changes in Sexual Functioning Questionnaire Short-Form (CSFQ-14) (Keller et al. 2006) is 
validated scale with internal reliability designed to allow a patient to self-evaluate his or her 
sexual behaviors or problems in a number of areas.  The CSFQ-14 will be administered at 
Baseline (Visit 2) and Week 12/ET (Visit 6).  It yields a total score, three subscales 
corresponding to phases of the sexual response cycle (i.e. desire, arousal, orgasm), and five 
subscales corresponding to important dimensions of sexual functioning.  It is considered a useful 
scale for assessing sexual side effects of medications.  For all items, higher scores reflect higher 
sexual functioning.  For 12 of the 14 items, higher sexual functioning corresponds to greater 

Protocol No TNX-CY-P301

Version 1.4 29Oct2019 
 
Page 58 of 87 
 
frequency or enjoyment/pleasure (e.g. 1=never to 5 = every day).  For two items (item 10, 
assessing loss of interest after arousal for women and priapism for men, and item 14, assessing 
painful orgasm), higher sexual functioning corresponds to lower frequency (e.g. 1=every day to 
5=never). Items 10 and 14 are included in the total score but not in any scale score. 
11.3.10. 
Assessment of Sedation:  Morning Treatment-Related Sedation Score (MTRSS) 
The Morning Treatment-Related Sedation Score (MTRSS) is designed to assess the patient’s 
morning sedation at clinic visits.  The MTRSS will be assessed at Baseline (Visit 2) and at 
Weeks 4, 8, and 12/ET (Visits 4, 5, and 6).  The patient will complete the following questions: 
A.  On most mornings during the past week, I have awakened feeling: 
0. Alert with no grogginess 
1. Mildly groggy 
2. Moderately groggy 
3. Very groggy 
B. If you reported any grogginess in the last week (responses 1-3), the grogginess lasted: 
1. A few minutes 
2. A short time (less than one hour) 
3. A long time (more than one hour) 
Note: if “Alert with no grogginess is selected in Part A, Part B is not answered, and the score for 
part B is 0. 
 
11.4. 
Pharmacogenomic Assessment 
For pharmacogenomic analysis, a single blood sample collected in one PAXgene DNA tube will 
be obtained from an invited group of patients at 5 study sites after participation in the main study 
has ended.  Patients had to have received active drug during the main study, at least one CAPS-5 
assessment post-Baseline, and the patient has provided separate written, signed informed consent 
for pharmacogenomic analysis. The blood sample will be sent by the site to the 
pharmacogenomics testing laboratory where first DNA is extracted from the whole blood 
sample, and subsequently exome sequencing is performed on the DNA. The purpose of this 
testing is to allow exome sequencing and analysis for genetic variants related to treatment 
response and presence or absence of adverse events to TNX-102 SL.  
12. 
DEFINITIONS, RECORDING, AND REPORTING OF ADVERSE 
EVENTS 
12.1. 
Definition of Adverse Events 
According to International Conference on Harmonization (ICH) guidance E2A, Clinical Safety 
Data Management: Definitions and Standards for Expedited Reporting, an adverse event (AE) is 

Protocol No TNX-CY-P301 
 
CONFIDENTIAL 
 
 
Version 1.4 29Oct2019 
 
Page 59 of 87 
 
any untoward medical occurrence in a patient or clinical investigation patient administered a 
pharmaceutical product and which is not necessarily required to have a causal relationship with 
this treatment.  An AE can therefore be any unfavorable and unintended sign (including an 
abnormal laboratory finding, for example), symptom, or disease temporally associated with the 
use of a medicinal product, whether or not considered related to the medicinal product. 
A treatment-emergent AE (TEAE) is an AE that either commenced following initiation of study 
treatment or was present prior to study treatment but increased in frequency or severity following 
initiation of study treatment. 
12.2. 
Adverse Event Recording 
12.2.1. 
Coding the Adverse Event 
Standard medical terminology should be used in describing AEs.  MedDRA® will be used as the 
standard coding dictionary for AEs and in describing the patient’s medical history, and the 
World Health Organization (WHO) Drug Dictionary will be used to code concomitant 
medications.  Informal descriptions should be avoided. 
12.2.2. 
Severity of Adverse Event 
AEs should be graded as mild, moderate, or severe using the following definitions. 
• 
Mild: Awareness of signs or symptoms, but easily tolerated and of minor irritant type 
causing no loss of time from normal activities.  Symptoms do not require therapy or a 
medical evaluation; signs and symptoms are transient. 
• 
Moderate: Events introduce a low level of inconvenience or concern to the patient and 
may interfere with daily activities, but are usually improved by simple therapeutic 
measures; moderate experiences may cause some interference with functioning. 
• 
Severe: Events interrupt the patient’s normal daily activities and generally require 
systemic drug therapy or other treatment; they are usually incapacitating. 
To make sure there is no confusion or misunderstanding of the difference between the terms 
“serious “and “severe,” which are not synonymous, the following note of clarification is 
provided.  The term “severe” is often used to describe the intensity (severity) of a specific event 
(as in mild, moderate, or severe myocardial infarction); the event itself, however, maybe of 
relatively minor medical significance (such as severe headache).  This is not the same as 
“serious,” which is based on patient/event outcome or action criteria usually associated with 
events that pose a threat to a patient's life or functioning.  Seriousness (not severity) serves as a 
guide for defining regulatory reporting obligations. 
12.2.3. 
Relationship of Adverse Events to Study Drug 
The investigator will assess the potential relationship of the AE to study drug using the following 
descriptions. 
• 
Not Related: This category applies to an AE that is clearly not related to the 
investigational agent/procedure, beyond a reasonable doubt.  That is, another cause of the 
event is most plausible; and/or a clinically plausible temporal sequence is inconsistent 

Protocol No TNX-CY-P301 
 
CONFIDENTIAL 
 
 
Version 1.4 29Oct2019 
 
Page 60 of 87 
 
with the onset of the event and the administration of study drug and/or a causal 
relationship is considered biologically implausible. 
• 
Unlikely Related: This category applies to an AE that could reasonably be considered 
caused by something else, and where there is no known or expected response pattern to 
the suspected study drug. 
• 
Possibly Related: This category applies to an AE that follows a reasonable temporal 
sequence from administration of the study drug and that follows a known or expected 
response pattern to the suspected study drug, but that could readily have been produced 
by a number of other factors. 
12.3. 
Serious Adverse Events (SAEs) and Serious Adverse Drug Reactions 
Any SAE that occurs at any time during the study, including a clinically significantly abnormal 
laboratory test result that is considered serious, must be reported to Tonix or its designee(s) so 
that Tonix may comply with regulatory obligations.  If the SAE is life-threatening or fatal, it 
must be reported to Tonix or its designee(s) immediately, by facsimile and telephone.  For these 
and all other SAEs, an SAE report form must be completed and sent by facsimile or email to 
Tonix or its designee(s) within 1 working day of the site’s initial awareness of the event.  These 
requirements apply equally to all patients, regardless of the study phase or the at-risk patient’s 
treatment assignment or dosage. 
A serious adverse event (experience) or reaction is any untoward medical occurrence that, at any 
dose: 
• Results in death, 
• Is life-threatening, 
• Requires in-patient hospitalization or prolongation of existing hospitalization, 
• Results in persistent or significant disability/incapacity, 
• Is a congenital anomaly/birth defect, or 
• Is an important medical event 
NOTE: The term “life-threatening” in the definition of “serious” refers to an event in which the 
patient was at risk of death at the time of the event.  It does not refer to an event that 
hypothetically might have caused death if it were more severe. 
Medical and scientific judgment should be exercised in deciding whether expedited reporting is 
appropriate in other situations, such as important medical events that may not be immediately 
life-threatening or result in death or hospitalization but may jeopardize the patient or may require 
intervention to prevent one of the other outcomes listed in the definition above.  These should 
also usually be considered serious.  Examples of such events are intensive treatment in an 
emergency room or at home for allergic bronchospasm, blood dyscrasias or convulsions that do 
not result in hospitalization, or development of drug dependency or drug abuse. 
A death occurring during the study, during the per-protocol follow-up period, or reported to the 
Investigator after study participation (no required post-study time limit) must be reported to 
Tonix or its designee(s) immediately, whether or not it is considered treatment-related.  Initial 
SAE reports must be followed by detailed descriptions.  These should include copies of hospital

Assessment of Demographic and Baseline Characteristics 
Demographic and baseline characteristics such as age, gender, race/ethnicity, height, weight, 
BMI, presence of current major depressive episode, family status, education, employment status, 
and smoking history will be summarized by treatment group (TNX-102 SL and placebo) and 
overall using descriptive statistics. 
Medical History will be coded using MedDRA and summarized by SOC and Preferred Term 
using frequency counts by treatment group. 
13.4.

• Change from baseline in BDI-II score after 12 weeks of treatment. 
• Change from baseline in CAPS-5 Reckless or Self-Destructive Behavior (item E-2) 
score after 12 weeks of treatment.  
 
Exploratory Endpoints:  Any exploratory endpoints will be delineated in the SAP.   
13.4.2. 
Primary Efficacy Analysis 
The primary efficacy analysis will use a mixed model repeated measures (MMRM) approach to 
estimate mean change from baseline in the Total CAPS-5 score evaluated after 12 weeks of 
treatment in the TNX-102 SL 5.6 mg and placebo arms.  The model will include all patients in 
the mITT population, and the dependent variable will be the observed change from baseline in 
total CAPS-5 score at each post-randomization visit.  Covariates in the model will include the 
fixed categorical effects of treatment, site, sex, current tobacco use status, presence of current 
MDE, visit and treatment by visit interaction, as well as the continuous fixed covariates of 
baseline score and baseline score by visit interaction.  Missing data will be imputed via multiple 
imputation (MI), and details regarding the MI approach will be described in the SAP.   

Protocol No TNX-CY-P301 
 
CONFIDENTIAL 
 
 
Version 1.4 29Oct2019 
 
Page 65 of 87 
 
The primary analysis will be followed by several sensitivity analyses.  Further details on 
sensitivity analyses can be found in the SAP. 
13.4.3. 
Secondary Efficacy Analyses 
MMRM methodology will be utilized for the continuous secondary endpoints, and analyses will 
be based on the mITT population.  The dependent variable will be the observed change from 
baseline in the respective secondary endpoint at each post-randomization visit, with the 
exception of the CGI-I which does not have a baseline.  Covariates in the model will include the 
fixed categorical effects of treatment, site, sex, current tobacco use status, presence of current 
MDE, visit and treatment by visit interaction (baseline score and baseline score by visit 
interaction will be included as appropriate).   
Binary data will be analyzed using a Cochran-Mantel-Haenszel test controlling for the 
randomization stratification of presence of current MDE, analyzed separately at each visit.  
Patients with missing data will be analyzed as though they are non-responders. The primary time 
point of interest will be Week 12.  Odds ratios and corresponding 95% confidence intervals will 
be presented. 
To adjust for multiplicity and to control for overall type I error, a sequential test procedure will 
be applied to the key secondary efficacy endpoints.  If the primary analysis produces a result that 
is statistically significant, a nominal significance level will be used for comparing the secondary 
endpoints in an ordered fashion.  If the analysis for a secondary endpoint does not produce a 
statistically significant result, then the remaining secondary endpoint analyses will automatically 
be considered non-significant regardless of the p-value produced.  In the case of an early stop or 
increase in sample size, the same methodology/critical value used for the primary endpoint will 
be applied to the key secondary endpoints for the purposes of the sequential testing.  See the SAP 
for additional details. 
The testing order for the two key secondary endpoints is as follows: 
• CGI-I score (analyzed as a continuous variable) after 12 weeks of treatment. 
• Change from baseline in the SDS total score after 12 weeks of treatment. 
No other adjustments for multiplicity will be made and other p-values displayed in the output 
will be considered for descriptive summary purposes only and will not be used for formal 
inference.  Full details regarding the statistical analyses for the listed endpoints will be provided 
in the SAP. 
13.4.4. 
Exploratory Analyses 
Exploratory efficacy analyses will be based on the mITT population.  Details on exploratory 
efficacy analyses can be found in the SAP. 
13.5. 
Safety Analyses 
Safety will be assessed by: 
• Adverse events and serious AEs throughout the entire duration of the study, including 
assessment of AEs involving the oral cavity 

Protocol No TNX-CY-P301 
 
CONFIDENTIAL 
 
 
Version 1.4 29Oct2019 
 
Page 66 of 87 
 
• Changes from baseline in clinical laboratory test results 
• Changes from baseline in vital signs and weight 
• Changes from baseline indicative of increased suicidal ideation or behavior as 
assessed by the C-SSRS 
• Changes from baseline in BDI-II 
• Changes from baseline in patient-rated sexual function as assessed by the CSFQ-14 
• Changes from baseline in patient-rated morning sedation as assessed by the MTRSS 
Adverse events will be coded using the latest version of MedDRA and will be summarized 
overall and by preferred term and system organ class.  Adverse events will also be summarized 
by severity and relationship to study drug.  Serious AEs and AEs leading to discontinuation of 
study drug will also be summarized.  Actual values and changes from Baseline for clinical 
laboratory test results, MTRSS scores, CSFQ-14 scores, BDI-II scores, and vital sign 
measurements will be summarized at endpoint using descriptive statistics (n, mean, SD, median, 
minimum, and maximum). 
The number of patients with suicidal behaviors, ideations and acts based on the C-SSRS will be 
tabulated by treatment group and listed. 
13.6. 
Interim Analyses 
One planned interim analysis for the purposes of sample size reassessment and to assess stopping 
early for either futility or success will be performed.  The interim analysis will be conducted 
when approximately 50% of the total planned enrollment is evaluable for efficacy. 
An adaptive group sequential design will be used for early efficacy testing.  The details of this 
testing will be described in an ISAP, which will be finalized prior to the interim analysis. 
The interim analysis will be performed by an independent unblinded statistical group.  Results of 
this assessment will be provided to an Independent Data Monitoring Committee (IDMC).  The 
IDMC Charter will outline the roles and responsibilities of the IDMC as well as the interim 
analysis decision rules.   
The following recommendations can be made at the time of the interim analysis: The IDMC will 
inform the Sponsor to increase the sample size by a fixed amount, keep the current sample size 
and continue, stop the study for futility, or stop the study early for success.  If the study is 
stopped early for success based on the interim analysis results, currently randomized patients 
who have not yet completed the study will be offered an immediate transition into an open-label 
extension safety study (Protocol No. TNX-CY-P306).

PROCEDURES FOR MODIFYING THE PROTOCOL OR 
TERMINATING THE STUDY 
14.1. 
Protocol Modifications and Deviations 
The investigator will make all reasonable efforts to comply with the written protocol and 
protocol amendments.  All protocol modifications must be reviewed and approved by the 
appropriate EC/IRB before the revised protocol can be implemented.  Emergency revisions that 
eliminate an apparent hazard to patients do not require preapproval by the EC/IRB.  However, 
the EC/IRB must be notified, in writing, as soon as possible after the modification has been 
made.  A copy of this communication must be forwarded to Tonix. 
14.2. 
Study Termination 
The study may be prematurely terminated at any time at the discretion of Tonix, its designee, or 
the principal investigator.  Should premature termination be considered necessary, written 
notification documenting the reason for study termination will be provided, and specific 
procedures for termination will be arranged.  Circumstances that may warrant premature study 
termination include, but are not limited to, the following. 
• 
Determination of unexpected, significant, or unacceptable risk to patients 
• 
Failure to enter patients at an acceptable rate 
• 
Insufficient adherence to the requirements of the protocol 
• 
Insufficient provision of complete and evaluable data 
• 
Plans to modify, suspend, or discontinue development of the study drug 
In the event that the study is terminated prematurely, all study materials must be returned to 
Tonix or its designee.

Ethical Conduct of the Study 
This protocol is written in accordance with the principles established by the 18th World Medical 
Assembly General Assembly (Helsinki, 1964) and amendments and clarifications adopted by 
subsequent General Assemblies.  The investigator will make sure that the study described in this 
protocol is conducted in full conformance with those principles, the protocol, current FDA 
regulations, ICH Good Clinical Practices (GCP) guidelines, Good Laboratory Practices (GLP) 
guidelines, local ethical and regulatory requirements, including the Federal Food, Drug and 
Cosmetic Act, U.S. applicable Code of Federal Regulations (title 21), any EC requirements 
relative to clinical studies.  As required by the US FDA, the study drug may not be shipped to 
any participating investigator until the requisite study documentation has been submitted to the 
IND. 
Should a conflict arise, the investigator will follow whichever law or guideline affords the 
greater protection to the individual patient.  The investigator will also make sure he or she is 

Protocol No TNX-CY-P301 
 
CONFIDENTIAL 
 
 
Version 1.4 29Oct2019 
 
Page 68 of 87 
 
thoroughly familiar with the appropriate administration and potential risks of administration of 
the study drug, as described in this protocol and the Investigator’s Brochure, prior to the 
initiation of the study. 
15.2. 
Ethics Committee/Institutional Review Board (EC/IRB) Review 
The EC/IRB must be a properly constituted board or committee operating in accordance with 21 
CFR Part 56, “Institutional Review Boards.”  This protocol, any protocol amendments, the 
associated informed consent forms, and the informed consent procedures must be submitted to 
the EC/IRB for review and approved before the enrollment of any patient into the trial. 
All types of patient recruitment or advertising information must be submitted to Tonix or its 
designee and to the EC/IRB for review and approval prior to implementation.  EC/IRB approval 
of any protocol amendments must be received before any of the changes outlined in the 
amendments are put into effect, except when the amendment has been enacted to eliminate a 
potential hazard to study patients.  In such cases, the chair of the EC/IRB should be notified 
immediately and the amendment forwarded to the EC/IRB for review and approval. 
15.3. 
Written Informed Consent 
It is the responsibility of the investigator to obtain signed written informed consent from each 
potential study patient prior to the conduct of any screening or other study procedures.  This 
written informed consent will be obtained after the methods, objectives, and potential risks of the 
study have been fully explained to the potential patient.  The investigator must explain to each 
patient that he or she is completely free to refuse to enter the study or to withdraw from it at any 
time.  NOTE:  Patients on serotoninergic medications (e.g., triptans) should be warned of a 
potential serious drug interaction and should be advised to contact their study site immediately if 
they experience any symptoms that might represent possible serotonin syndrome, including 
fever, confusion or agitation, hallucinations, sweating, high or low blood pressure, rapid heart 
rate, tremor, muscle rigidity or nausea, vomiting or diarrhea.  Patients on MAOIs should not be 
considered for the study, and MAOIs should not be initiated during the study due to the 
additional safety concerns posed by this class of medication when used in combination with 
other serotoninergic drugs (such as cyclobenzaprine). 
The patient should also be asked in the Informed Consent Form (ICF) for permission for the 
principal investigator or his designee to contact the patient’s other personal physicians, as 
appropriate, concerning participation in the study. Separate written, signed informed consent 
must be obtained if the patient is to participate in the post-study optional pharmacogenomic 
assessment. 
The method of obtaining and documenting informed consent and the contents of the ICF will 
comply with International Conference on Harmonization (ICH) Good Clinical Practice (GCP) 
guidelines, the requirements of 21 CFR Part 50, “Protection of Human Patients,” the Health 
Insurance Portability and Accountability Act (HIPAA) regulations, and all other applicable 
regulatory requirements.  A properly executed written ICF shall be read, signed, and dated by 
each patient prior to entering the trial or prior to performing any study procedure.  The original 
signed and dated ICF will be kept on file at the study site.  Patients will be given a copy of the 

Protocol No TNX-CY-P301 
 
CONFIDENTIAL 
 
 
Version 1.4 29Oct2019 
 
Page 69 of 87 
 
signed ICF and will be informed of any new developments during the course of the study that 
might influence their continued participation in the study. 
The investigator or a qualified designee will be available to answer each patient’s questions 
throughout the study, and all questions must be answered to the patient’s satisfaction.  If the 
protocol is amended and a revised ICF is introduced during the study, each patient’s further 
consent must be obtained.  The new version of the ICF must be approved by the EC, prior to 
subsequently obtaining each patient’s consent. 
Receipt of written informed consent will be documented in each patient’s or potential patient’s 
CRF.  The signed ICF must remain in each patient’s study file and must be available for 
verification by study monitors at all times. 
16. 
DATA HANDLING AND RECORDKEEPING 
16.1. 
Maintaining Privacy and Confidentiality 
In order to maintain patient privacy, all CRFs, study drug accountability records, and other 
documents, including communications between the study site and Tonix, will identify patients 
only by their initials or their assigned study identification numbers.  If required, the investigator 
will grant monitors and auditors from Tonix or its designee and/or regulatory authority’s access 
to patients’ original medical records for verification of the data gathered on the CRFs and to 
audit the data collection process.  Patients’ confidentiality will be maintained and will not be 
made publicly available. 
Special Provisions for Confidentiality:  A Certificate of Confidentiality (CoC) has been 
obtained from the FDA for the investigators to protect patients enrolled in the study.  Investigator 
can use the Certificate to avoid compelled "involuntary disclosure" (e.g., subpoenas, insurers, 
employers, or other third parties) of names and other identifying information about any 
individual who participates as a research patient (i.e., about whom the investigator maintains 
identifying information) during any time the Certificate is in effect. 
16.2. 
Maintaining Essential Clinical Documents 
Study site files for the retention of regulatory documents will be established at the beginning of 
the study, maintained for the duration of the study, and retained according to FDA and ICH/GCP 
guidelines and applicable regulatory requirements.  The records maintained must be adequate to 
fully document appropriate protection of study patients/patients, the validity of the study, the 
integrity of the data, and the manner in which the study was conducted. 
The investigator’s site file, copies of protocols, CRFs, originals of test result reports, drug 
disposition logs, correspondence, records of written informed consent, and other documents 
pertaining to the conduct of the study must be kept on file by the investigator and in readily 
accessible order for at least 2 years after the last approval of a marketing application, until at 
least 2 years have elapsed after formal discontinuation of the clinical development of the 
investigational product, or according to local regulatory requirements.  No study document may 
be destroyed without prior written consent from Tonix or its designee.  Should the investigator 
wish to withdraw from the responsibility of keeping the study records, custody must be 

Protocol No TNX-CY-P301 
 
CONFIDENTIAL 
 
 
Version 1.4 29Oct2019 
 
Page 70 of 87 
 
transferred to a person willing to accept the responsibility.  Tonix must be notified in writing in 
advance if a custodial change is to occur.  It is important that the investigator remain ready to 
provide background information from the archived study records on request. 
The sponsor or designee will maintain adequate study records for at least 2 years after the last 
approval of a marketing application or for at least 2 years after clinical development of the study 
drug for the indication being studied has been discontinued.  After that period, the sponsor will 
be contacted to determine whether the study records will be forwarded to the sponsor, destroyed, 
or kept at the location of the designee or another facility for a longer period of time. 
16.3. 
Data Handling 
Unless otherwise specified, procedures, data collection and evaluation will be conducted as per 
the Standard Operating Procedures (SOPs) of the contract research organization (CRO).  The 
investigator will assume the responsibility of ensuring the completeness and accuracy of the 
clinical data.  All data will be verified for quality control and will also be patient to audits from 
Tonix or designee to ensure quality. 
All laboratory results will be analyzed by an accredited and licensed clinical laboratory facility.  
Clinical laboratory data will be transferred from the central laboratory to the clinical database 
maintained by the CRO using systems which are validated and Part 11-compliant. 
The responsible clinical study monitor(s) will check data at the monitoring visits to the clinical 
study site.  The investigator will ensure that the data collected are accurate, complete, and 
legible.  Any changes made to the clinical data will be documented with a full audit trail. 
Aspects of the clinical and statistical phases of the study, including all associated documentation 
may be reviewed by the Quality Assurance Unit of the contract research organization using a 
risk-assessment approach.  The final clinical and statistical report will be audited to ensure that, 
as far as can be reasonably established, the methods described and the results reported accurately 
reflect the raw data generated during the study. 
16.4. 
Case Report Forms (CRFs) 
The investigator is required to prepare and maintain adequate and accurate case histories 
designed to record all observations and other data pertinent to the study for each study patient.  
Data must be recorded on CRFs approved by Tonix or its designee.  Data (including AEs) will be 
recorded on raw data sheets and/or electronic or paper source documents. 
If selected data is collected via paper (patient questionnaires, etc.), the data must be entered into 
the eCRF and verified that it has been transcribed correctly. 
16.5. 
Screening Records 
A record generated by IWRS must be kept of all patients considered for the study who sign 
informed consent and who began any screening procedures.  The information should include the 
patient’ initials, unique patient identification numbers, whether they passed or failed screening, 
and, if they failed, the reason for screen failure.

16.6. 
Clinical Laboratory Certification 
A central clinical laboratory will be used to analyze all samples in this study, with the exception 
of the urine pregnancy test and ad hoc urine drug screens.  The investigator must maintain, on 
file, written evidence that the central clinical laboratory to be used is certified under the Clinical 
Laboratory Improvement Act or equivalent certification (depending on local regulations).  
Further, the investigator will maintain a copy of the certification, the range of normal values, the 
effective dates for the ranges, and the units of measurement for all laboratory tests requested in 
the protocol.  If any of the laboratory measurements will be transformed and/or categorized in 
any way, a description of the procedures(s) used should be included.  The investigator is 
expected to receive these documents before the shipment of clinical supplies. 
16.7. 
Site Monitoring and Tonix’s Right to Review Records 
Monitoring and auditing procedures developed by Tonix and/or its designee will be implemented 
to ensure compliance with FDA and ICH GCP and GLP guidelines. 
Tonix’s designated representative (the monitor or auditor) will contact the investigator and 
conduct regular visits to the clinical site.  The monitor will be expected and allowed to verify the 
investigator’s qualifications, to inspect clinical site facilities, and to inspect study records, 
including proof of EC/IRB review, with the stipulation that patient confidentiality will be 
maintained in accordance with local and federal regulations, including HIPAA requirements.  
The monitor will also be responsible for confirming adherence to the study protocol, inspecting 
CRFs and source documents, and ensuring the integrity of the data.  CRFs will be checked for 
accuracy, completeness, and clarity and will be cross-checked for consistency with source 
documents, including laboratory test reports and other patient records.  Instances of missing or 
uninterpretable data will be resolved in coordination with the investigator. 
The monitor/auditor will also investigate any questions concerning adherence to regulatory 
requirements.  Any administrative concerns will be clarified and followed.  The monitor will 
maintain contact with the site through frequent direct communications with the study site by e-
mail, telephone, facsimile, and mail.  The investigator and all other site personnel agree to 
cooperate fully with the monitor and will work in good faith with the monitor to resolve any and 
all questions raised and difficulties detected by the monitor. 
16.8. 
Audits and Inspections 
The investigator understands that regulatory authorities, the EC/IRB, and/or Tonix or their 
designees have the right to access all CRFs, source documents, and other study documentation 
for on-site audit or inspection and will retain this right from the start of the study to at least 2 
years after the last approval of a marketing application or for at least 2 years after clinical 
development of the study drug for the indication being studied has been discontinued.  The 
investigator is required to guarantee access to these documents and to cooperate with and support 
such audits and inspections.

CONFIDENTIALITY 
17.1. 
Protection of Patient Anonymity 
The investigator must make sure that each patient’s anonymity is maintained.  On CRFs or other 
documents submitted to Tonix or its agent, patient should not be identified by their names, but 
rather by their initials and the assigned study identification numbers.  The investigator should 
keep a separate record of the patient initials, randomization codes, patient names, address, and 
contact information.  Documents that contain the names associated with these initials and codes 
are not for submission to Tonix or its agents (e.g., written informed consent forms).  These 
records should be maintained by the investigator in strict confidence except to the extent 
necessary to allow auditing by regulatory authorities, Tonix, or its agents.  These records should 
be kept in compliance with HIPAA regulations. 
Special Provisions for Confidentiality:  In addition, Certificates of Confidentiality has been 
obtained from the FDA for the investigators to protect patients enroll in the study.  Investigators 
can use the Certificate to avoid compelled "involuntary disclosure" (e.g., subpoenas, insurers, 
employers, or other third parties) of names and other identifying information about any 
individual who participates as a research patient (i.e., about whom the investigator maintains 
identifying information) during any time the Certificate is in effect. 
17.2. 
Confidentiality of Study Information 
All information relevant to this study, whether supplied by Tonix or its agents to the investigator 
or collected by the investigator in support of this study, is privileged and confidential.  The 
investigator agrees to use this information to carry out the study and will not use it for other 
purposes without written consent from Tonix.  It is understood that the investigator is under 
obligation to provide Tonix with all data obtained during the study.  The information obtained 
from this study will be used by Tonix towards the clinical development of the indicated 
investigational drug and may be disclosed by Tonix to regulatory authorities, other investigators, 
corporate partners, or consultants as required. 
17.3. 
Publication of Data and Protection of Trade Secrets 
No presentations, abstracts (including meeting abstracts), or other publications based on the 
conduct or results of this study will be permitted without the express written permission of Tonix 
or its designated agent.  All such presentations or publications will proceed only as 
collaborations between Tonix and the investigators. 
If the investigator wishes to publish the results of this study, a copy of the proposed manuscript 
or abstract (including meeting abstracts) will be provided to Tonix or its designee for review, 
revision, and approval at least sixty (60) days before the expected date of submission for 
publication, unless otherwise arranged with Tonix in writing.  This will enable Tonix to protect 
its proprietary information and augment the publication with insights or information of which the 
investigator may not be aware. 
Patient names and other identifiers, such as photographs or audio or video recordings, may not 
be disclosed in any publication or public forum without prior written authorization from the
