SYNOPSIS 
Protocol Title: 
Open-label, non-controlled, single-ascending dose study to evaluate safety, 
tolerability, pharmacokinetics, and exploratory efficacy of KTP-001 in 
subjects with lumbar disc herniation 
Sponsor: 
Teijin America, Inc. 
Study Phase: 
Phase 1/2 
Indication: 
Herniated lumbar disc 
Objectives: 
The primary objective of this study is: 
• 
To evaluate the safety and tolerability of a single intradiscal injection 
of KTP-001 in subjects with a single herniated lumbar disc. 
The secondary objectives of this study are: 
• 
To determine the pharmacokinetics (PK) of KTP-001 in the serum of 
circulating blood after intradiscal injection of the study drug. 
• 
To determine the presence of anti-KTP-001 antibody in the serum of 
circulating blood after intradiscal injection of the study drug. 
The exploratory objectives of this study are: 
• 
To explore the pharmacodynamics (PD) of keratan sulfate in the serum 
of circulating blood after intradiscal injection of the study drug.  
• 
To assess changes in pain, neurologic examination, disability, magnetic 
resonance imaging (MRI) and X-ray assessments, Quality of Life 
(QOL), and patient global impression of change (PGI-C) scores in 
subjects receiving study drug. 
Number of Sites: 
This study will be conducted at approximately 8 sites in the United States. 
Study Design: 
This study is designed as an open-label, non-controlled single ascending 
dose study. Twenty-four subjects with a diagnosis of a single herniated 
lumbar disc will be divided into 4 cohorts of 6 subjects. Dose escalation 
will begin with a 5 μg intra-disc administration. After all subjects in the 
first cohort have reached the Week 13 assessment, relevant safety data will 
be reviewed. If adequate safety and tolerability has been demonstrated, 
KTP-001 dose escalation will continue in subsequent escalating doses of 
15, 50, and 150 μg/disc with safety reviews conducted prior to each dose 
escalation.  
Planned Sample Size: 
Approximately 48 subjects will be screened to ensure that 24 subjects are 
enrolled into this study. Subjects who discontinue from the study after 
enrollment but prior to receiving study drug will be replaced to ensure that 
at least 6 subjects are treated in each of the 4 cohorts.

Duration of Study: 
After a single intradiscal injection of study drug, subjects will be confined 
to the study facility for the first 24 hours and will be asked to participate in 
this study for at least 24 months (2 years). 
Study Drug: 
KTP-001 1.0 mg/vial will be provided as a lyophilized powder in 2.0 mL 
glass vials. Each vial contains 1.0 mg of KTP-001 drug substance, which 
will be reconstituted with 0.5 mL of sterile water for injection and then 
diluted with a buffer solution to administer the required injection dose per 
1.0 mL. 
Dose and Route of 
Administration: 
A single intradiscal injection of doses 5, 15, 50, and 150 µg/disc of 
KTP-001 will be administered intradiscally under fluoroscopic or computer 
tomography (CT) visualization and guidance after a local anesthetic is 
administered. The final injection volume per subject will be 1.0 mL. Use of 
an imaging dye is not permitted for the intradiscal injection. 
Response Criteria: 
Safety 
Measures of safety and tolerability will include vital signs, 12-lead ECGs, 
determination of adverse events (AEs), clinical laboratory (hematology, 
serum chemistry, coagulation, urinalysis), MRI, X-ray (morphological 
assessment), and physical and neurologic examinations.  
 
Blood samples for measures of serum anti-KTP-001 antibody will be drawn 
pre-dose (just prior to administration of study drug) and at the 1-, 2-, 4-, 6-, 
and 13-week visits post-dose or early termination visit. 
 
Data and Safety Monitoring Board (DSMB): 
Escalation to a higher dose in a cohort will be permitted only if adequate 
safety and tolerability have been demonstrated at the previous lower dose. 
An independent Data and Safety Monitoring Board (DSMB) will determine 
whether to proceed to the next dose level as planned by evaluating safety 
measures, including AEs and clinical laboratory values. This evaluation 
will be conducted at the 13-week follow-up visit for all subjects in each 
dose cohort.

Evidence by X-ray of lumbar segmental instability at the treated 
segment defined as either: 
o 
Anterior translation of the posterior edge of the superior 
vertebral body relative to the posterior edge of the inferior 
vertebral body increase from baseline greater than 3 mm 
is considered strong evidence of instability  
o 
Sagittal rotation change from extension to flexion of >5° 
(as measured by the Dupuis method) is weak evidence of 
instability, and without observed translation as defined 
above, will require further evaluation before it would be 
considered a halting event 
 
NOTE: if the subject’s condition does not permit the 
acquisition of flexion and extension films, instability will 
be evaluated solely on the basis of translation on the 
lateral view, as described above 
• 
Destructive cartilage endplate changes as confirmed by MRI. 
 
Efficacy (exploratory) 
The following measures of efficacy after administration of study drug will 
be explored in this study: 
• 
Lower back pain and leg pain (measured by 11-point numerical pain 
scale) at baseline, on Day 1 pre-dose, at 2, 4, 6, and 24 hours 
post-dose, at all post-dose visits (Weeks 1, 2, 4, 6 and 13, Months 6, 9, 
12, 18, 24 or early termination visit).

INTRODUCTION AND BACKGROUND 
3.1 
Introduction 
Teijin is developing recombinant human Matrix metalloproteinase 7 (MMP-7, code name:   
KTP-001) for chemonucleolysis therapy for the relief of herniated disc, characterized by a 
protrusion or prolapse of the nucleus pulpous through the annulus fibrosus, which in turn presses 
against a nerve, and causes lower back pain and/or leg pain.  
The prevalence of lumbar disc herniation is approximately 1% of the population [1]. Patients with 
severe neurological deficits such as cauda equina syndrome will have surgery immediately. Of 
the remaining patients who opt for conservative therapy, approximately 10 to 54% will not be 
satisfied with the treatment [2-6]. Currently, when conservative therapy does not provide sufficient 
relief, the physician has 3 options:  to continue with conservative therapy; administer epidural 
steroid injections/selective nerve root blocks or intradiscal therapies; or perform surgery.  
Surgery eliminates nerve impingement directly and often achieves immediate relief. However, 
this technique is invasive and has risk related to the operation such as muscle, ligament, bone and 
nerve root damage. Intradiscal therapies such as percutaneous nucleotomy, percutaneous laser 
disc decompression or intradiscal electrothermal annuloplasty are less invasive compared with 
surgery, but the patient has to be carefully selected because the hernia type to which this 
technique is applicable is strictly defined. Therefore, it is desirable to develop a novel treatment 
that is efficacious, safe and applicable to broad types of hernia. 
Chemonucleolysis is a procedure that dissolves the matrix in the herniated disc by the intradiscal 
injection of an enzyme. The technique is very simple and less invasive than current surgery and 
is expected to contribute to shortened hospital stays. No drug for chemonucleolysis is currently 
available in the US. A novel and promising agent that can be used for chemonucleolysis is 
desired. 
Proteoglycans are the main solid components of the nucleus pulposus. MMP-7 enzymatically 
cleaves aggrecan, the major proteoglycan of the disc [7-8]. MMP-7 is significantly expressed in 
surgical samples of human herniated discs and degrades in vitro and in vivo proteoglycans. 
MMP-7 is an endogenous protease that results in the natural resorption of a herniated disc [9-10]. 
From a theoretical standpoint, recombinant human MMP-7 should be ideal for the purpose of 
chemonucleolysis because of its lack of antigenicity in humans and its substrate selectivity 
toward proteoglycans. 
Based on the scientific background above, Teijin and Kaketsuken intend to develop recombinant 
human MMP-7 as a novel therapeutic agent for lumbar disc herniation. Kaketsuken has 
established the manufacturing process for pharmaceutical grade recombinant human MMP-7 
(KTP-001) 
 Teijin has completed extensive

nonclinical studies to support this first-in human (FIH) study in subjects with lumbar disc 
herniation.

Description of Investigational Product 
KTP-001 is a recombinant human MMP-7 
 
KTP-001 is supplied as a lyophilized powder, which is reconstituted using 0.5 mL of sterile 
water before injection.   
3.3 
Nonclinical Studies 
Complete information for this compound may be found in the Investigator’s Brochure (IB). 
Summaries of nonclinical drug development studies are presented below to support the rationale 
for the proposed study design and doses selected for clinical evaluation. 
3.3.1 
Primary Pharmacology 
Because KTP-001 digests proteoglycan (including aggrecan), the proteoglycan content of the 
nucleus pulposus was selected as a marker in the nonclinical development program to evaluate 
the effects of KTP-001 on nonherniated lumbar discs in animals.
 
 
 
The proteoglycan content of the nucleus pulposus was determined by the intensity of alcian blue 
staining; the breakdown of aggrecan in the nucleus pulposus by KTP-001 was assessed by 
measures of the serum concentrations of keratan sulfate, and a decrease of disc height was 
assessed using disc height index.

STUDY DESIGN 
5.1 
Design Summary 
Study KTP-001-CL-101 is an open-label, non-controlled single ascending dose study of 
KTP-001 in male and female subjects between the ages of 30 and 70 with a single herniated 
lumbar disc. After obtaining informed consent, subjects will be evaluated during a screening 
period of no more than 3 weeks (21 days). The following procedures will be performed at the 
screening visit: collection of subject baseline demographics, medical history (including the 
symptoms associated with herniated lumbar disc), prior medications, height, weight, a full 
physical and neurologic examination (including straight-leg raising and femoral stretch test), and 
collection of vital signs, 12-lead ECG, and clinical laboratory tests (hematology, serum 
chemistry, coagulation, urinalysis, and urine drug screen). A serum pregnancy test will be 
conducted for female subjects of childbearing potential. The following baseline exploratory 
efficacy measures will be assessed: lower back and leg pain using a numerical scale (using a 
subject diary for 5 consecutive days prior to treatment), spinal flexion/tension using straight-leg 
raising and femoral stretch test, MRI assessment, lumbar spine X-ray assessment, the severity of 
disability using the Oswestry Disability Index (ODI), QOL using the Short Form-12 (SF-12) 
questionnaire, and symptom severity as measured by the PGI-C scale. A pain assessment diary 
will be administered and collected between screening and treatment on Day 1. 
Subjects that meet all screening requirements and inclusion criteria and none of the exclusion 
criteria will be enrolled into 1 of 4 study cohorts and receive KTP-001. Following administration 
of study drug, subjects will be confined to the study unit for 24 hours to collect data for safety 
and efficacy measures and collect blood samples for the following purposes: safety, PK 
evaluation, and exploratory PD (keratan sulfate), including anti-KTP-001 antibody. 
Subjects enrolled in Cohort 1 will have pre-dose assessments of concomitant medications, 
weight, physical and neurologic examinations, and vital signs. Female subjects will have a urine 
pregnancy test, and all subjects in the cohort will have blood samples taken for PK and PD 
analyses. Efficacy assessments will be repeated. Subjects in this cohort will receive a 5 µg/disc 
dose of KTP-001 by intradiscal injection. Subjects will be observed for 24 hours after injection 
to facilitate post-procedural monitoring and collection of additional PK samples. Subjects will 
return to the clinic for visits at Weeks 1, 2, 4, 6, and 13, and at Months 6, 9, 12 (1 year), 
Month 18 (1.5 years), and Month 24 (2 years) for safety, and exploratory efficacy assessments 
(including X-ray and MRI at Week 13 and Months 6, 12, 18, and 24). Subjects will be provided a 
study diary to record their level of leg and lower back pain on a daily basis up to Week 13. 
Thirteen weeks after all subjects in Cohort 1 have received study drug, safety measures will be 
evaluated by a Data and Safety Monitoring Board (DSMB) to determine whether to escalate

Page 30 of 92 
KTP-001 administration to the next dose level. This evaluation will be conducted after the 
13-week follow-up visit for all subjects in each dose cohort.
If escalation is appropriate as determined by the DSMB (see Section 5.1.2), then the Cohort 2 
subjects will receive KTP-001 15 µg/disc, Cohort 3 subjects will receive 50 µg/disc of KTP-001, 
and Cohort 4 subjects will receive 150 µg/disc of KTP-001 by intradiscal injection (Figure 5.1). 
All safety, PK, and exploratory efficacy assessments will be performed for the subjects in the 
subsequent cohorts as were performed for Cohort 1.

KTP-001-CL-101 Study Design 
5.1.1 
Treatments Administered 
The proposed clinical dose concentrations for this FIH study are 5 μg/disc (Cohort 1), 15 μg/disc 
(Cohort 2), 50 μg/disc (Cohort 3), and 150 μg/disc (Cohort 4). Single doses of the proposed 
clinical dose concentrations will be administered intradiscally at the level of lumbar disc 
herniation by injection under fluoroscopic or computerized tomography (CT) visualization and 
guidance to 24 male and female human subjects between the ages of 30 and 70 with a single 
herniated lumbar disc as confirmed by MRI.  
5.1.2 
Dose Escalation 
Escalation to a higher dose in a cohort will be permitted only if adequate safety and tolerability 
have been demonstrated at the previous lower dose level after review by the DSMB. The 
responsibilities of the DSMB are to monitor the safety and welfare of the study subjects by 
reviewing the data from the study at regular intervals and determining whether it is safe to 
continue the study according to the protocol. The DSMB will have the authority to recommend

stopping the study early or modifying the study design for safety concerns. Details regarding 
DSMB membership, dose escalation criteria, schedule and format of meetings, format for 
presentation of data, access to interim data, and other information relevant to the operations of 
the committee will be described in a separate DSMB charter. The DSMB will conduct a safety 
review at the 13-week follow-up visit for all subjects in each dose cohort.  
5.1.3 
Halting Rules 
The AEs or imaging abnormalities described below will be defined in this study as a halting rule 
(HR). If a HR occurs in any subject during the dose escalation phase of the study, further 
recruitment and dosing of the current study cohort will be held until the event is assessed by the 
DSMB. The DSMB will make a recommendation regarding continuation of the study and/or 
escalation to the next dose cohort when one of the following events occurs:  
•
Neurologic deficit consistent with cauda equina syndrome or myelopathy
•
Exacerbation of radicular symptoms associated with onset of a new motor deficit in one
or both legs following administration of study drug
•
Modic changes consistent with significant endplate edema or sclerosis compared to
baseline, as determined by an expert spine radiologist
•
Loss of height of the disc of > 30% relative to the baseline and defined as the average of
anterior and posterior disc height evaluated by X-ray
•
Evidence by X-ray of lumbar segmental instability at the treated segment defined as
either:
o
Anterior translation of the posterior edge of the superior vertebral body relative to
the posterior edge of the inferior vertebral body increase from baseline greater
than 3mm is considered strong evidence of instability
o
Sagittal rotation change from extension to flexion of >5° (as measured by the
Dupuis method)[11] is weak evidence of instability, and without observed
translation as defined above, will require further evaluation before it would be
considered a halting event
NOTE: if the subject’s condition does not permit the acquisition of flexion and
extension films, instability will be evaluated solely on the basis of translation on
the lateral view, as described above
•
Destructive cartilage endplate changes as confirmed by MRI.

Once the last 13-week follow up period after the last dose cohort has occurred, any future 
instances of these events will be reported as AESI, but will not be treated as a HR. Further details 
on the role of the DSMB to evaluate study conduct will be provided in a separate DSMB charter. 
5.1.4 
Duration of Study 
Subjects will be enrolled in this study for up to 24 months. After 24 hours of confinement, the 
subject will return to the clinic for visits at Weeks 1, 2, 4, 6, and 13, and at Months 6, 9, 12, 18, 
and 24 for safety and exploratory efficacy assessments. 
5.2 
Discussion of Study Design 
Because intradiscal injection is too invasive to be performed on healthy volunteers, this study 
will be conducted with patients with documented herniated lumbar discs. Due to the chronic pain 
caused by herniated lumbar discs, concomitant medications to control pain are necessary for this 
subject population.  
Calculations for the starting dose in this FIH study is based on nonclinical studies and described 
in Section 7.3. Based on these findings, the DSMB will review all relevant safety data after the 
Week 13 visit to guide subsequent dosage escalation, as appropriate. Further details on dose 
escalation criteria will be provided in a separate DSMB charter.

1. Initiation of treatment or change in the dose regimen is disallowed for antidepressants, 
anticonvulsants, or any prescription or over the counter pain modulating drugs from 
screening to 13 weeks post-dose. If subjects are on a stable dose of any of the above 
medications for at least 4 weeks prior to screening, the same dose regimen should be 
continued through 13 weeks post-dose. 
2. Initiation of treatment or dose escalation of muscle relaxants or sedatives/hypnotics is 
disallowed. A stable dose regimen if initiated at least 1 week prior to screening may be 
continued unchanged through 13 weeks post-dose. However, temporary use of a new 
muscle relaxant or sedative/hypnotic or dose increase of already used muscle relaxant or 
sedative/hypnotic will be allowed for treatment of a documented AE, for the duration of 
the event only. If clinically indicated, dose reduction or discontinuation of treatment is 
also permitted. 
3. Epidural steroid injections/selective nerve root block/facet block are allowed if medically 
necessary within the first 13 weeks post-dose and beyond. However, the indication for 
the procedure (e.g., intractable lower back pain/worsening of lower back pain) must be 
documented as an AE (or SAE if it meets the SAE criteria defined in Section 9.9.7). 
Subjects who require a surgical intervention for treatment of disc herniation will be 
discontinued from the study. 
4. Opioid and nonopioid analgesics (including topical analgesics) used for pain management 
on a stable dose at least 1 week prior to screening may be continued at the same or lower 
dose during the first 13 weeks post-dose. No dose escalation and no new opioid or 
nonopioid analgesics will be allowed except for acetaminophen. However, as described 
in Section 6.5.1, temporary use of a new analgesic or dose increase of an already 
administered analgesic will be allowed to treat a documented AE, for the duration of the 
event only. Daily doses of all analgesics including rescue doses of acetaminophen will be 
recorded by the subjects in the provided diaries. 
5. Systemic steroids are disallowed during the first 13 weeks post-dose, except for 
temporary use to treat a documented AE, for the duration of event only. Topical, 
ophthalmic and inhalation steroids are allowed. 
6. Subjects treated with a nonsteroidal anti-inflammatory drug (NSAID) should have their 
treatment discontinued at least 10 days prior to the study procedure. The NSAIDs may be 
restarted 24 hours post-dose. Use of an alternative analgesic during that period of time 
will be allowed at the discretion of investigator.  
7. Therapeutic intradiscal interventions including intradiscal injections, other than the study 
injection are not permitted in the study.

It is recommended that antiplatelet therapy be withheld prior to the study procedure for the 
duration of time consistent with the type of antiplatelet drug and local standard of care (on 
average 7 to 10 days). It may be restarted 24 hours after the procedure. A low dose aspirin (e.g., 
81 mg) for cardiovascular protection may be continued at the discretion of the investigator. 
6.5.4 
Disallowed Treatments 
Initiation of acupuncture, TENS, physical therapy modalities, biofeedback or psychotherapy are 
disallowed. Continuation of the same therapy modalities/frequency as received prior to screening 
is allowed (if prior therapy has been stable for at least 2 weeks prior to screening). Reduced 
frequency of treatments and discontinuation of prior therapy is allowed. The above restrictions 
do not apply beyond the Week 13 visit. 
6.5.5 
Tobacco and Alcohol Use  
Subjects are prohibited from using any tobacco products from 2 weeks prior to the study 
injection through 2 weeks post-dose. Consumption of alcohol should be limited to that defined in 
the exclusion criteria. 
6.6 
Subject Withdrawal and Discontinuation 
Subjects are free to discontinue the study at any time, for any reason, and without prejudice to 
further treatment. The investigator may remove a subject if, in the investigator’s judgment, 
continued participation would pose unacceptable risk to the subject or to the integrity of the 
study data.  
Subjects must discontinue from the study for any of the following reasons: 
• The subject experiences an intercurrent illness that in the opinion of the investigator 
indicates continued participation in the study is not in the subject’s best interest 
• The subject is unable or unwilling to comply with the protocol 
• The subject withdraws informed consent 
• The subject is lost to follow-up 
• The subject requires lumbar spine surgery 
• A female subject tests positive for pregnancy

STUDY DRUG 
7.1 
Description of Investigational Product 
The active ingredient of KTP-001 is recombinant human MMP-7 
 
 KTP-001 is a lyophilized powder for reconstitution provided in a sterile glass 
vial. Each vial contains 1.0 mg of KTP-001 drug substance in a 2 mL USP Type 1 glass vial to 
be reconstituted with 0.5 mL of sterile water for injection. Further details regarding the study 
drug are provided in the IB, and details on drug preparation for intradiscal injection will be 
provided in the Pharmacy Manual. 
7.2 
Treatments  
The study procedure should be performed under sterile conditions in an ambulatory surgical 
center, or special-procedure ambulatory radiology suite, or an operating room. The staff of 
treatment facility must be appropriately trained and prepared to respond to medical emergencies 
including the remote possibility of systemic allergic reaction. 
A single intradiscal injection of 5, 15, 50, or 150 µg/disc of KTP-001 will be administered 
intradiscally using a two-needle technique under fluoroscopic or CT visualization and guidance. 
The procedure will be performed under local anesthesia as per investigator’s standard of care. 
Light sedation will be allowed as per local standard of care. However, the subject must remain 
awake and able to cooperate during the procedure. The injection volume per subject will be 
1.0 mL. Use of an imaging dye is not permitted for the intradiscal injection. A prophylactic 
antibiotic may be used as per local standard of care. 
The intradiscal injection procedure is detailed in Appendix B. 
7.2.1 
Local Anesthetic and Chemonucleolysis Procedures 
Details on local anesthetic and chemonucleolysis procedures will be provided in the Study 
Manual. 
7.3 
Dose Rationale 
The disc volume where KTP-001 will be injected is a closed space as demonstrated in numerous 
animal studies, and therefore, the volume of the nucleus pulposus in animals and humans was 
used to calculate dose levels.

EFFICACY ASSESSMENTS 
The following efficacy measures are all exploratory in nature and all analyses will be presented 
using descriptive statistics. For all measures, the baseline value is defined as the last assessment 
result collected prior to the first dose of study medication. Unless otherwise noted, the endpoint 
for all efficacy measures will be changes from baseline at 6 and 13 weeks post-dose. 
8.1 
Lower Back or Leg Pain 
Lower back and leg pain will be assessed using an 11-point numerical rating scale in response to 
the questions provided in Appendix C at screening, for 5 consecutive days prior to Day 1, 
pre-dose, at 2, 4, 6, and 24 hours post-dose, and then daily until the Week 13 visit. A numerical 
rating scale is considered to be a valid and reliable means of measuring pain in subjects with 
chronic pain conditions [14].  
8.2 
Use of Rescue Medication or Surgical Intervention 
The number of subjects and amount of rescue medication will be recorded and summarized when 
any of the following occurs:  extra pain medication is administered that is in addition to the 
baseline pain regimen defined at screening prior to treatment, an epidural injection or a selective 
nerve root block within 13 weeks after receiving study drug, or surgical intervention for lumber 
disc herniation.  
8.3 
Spinal Flexion and Tension  
Spinal flexion and tension will be measured using the straight-leg raising or femoral stretch test 
at baseline, on Day 1 pre-dose, at 24 hours post-dose, and at all post-dose visits. Details on 
administering the straight-leg or femoral stretch test are provided in Appendix D.  
8.4 
Functional Ability 
The degree to which lower back or leg pain interferes with the subject’s ability to manage 
everyday tasks will be measured using the ODI (version 2.1A) and is provided in Appendix E.  
The ODI is a patient self-scored questionnaire in use since 1980. The ODI is a validated tool to 
measure how functional level is restricted by disability, and can also be used to determine 
improvement in functional levels as a result of treatment. The improvement or lack of 
improvement in functional level is determined as a change from baseline in the score. 
The ODI measures 10 areas of daily function:  pain intensity, personal care, lifting, walking, 
sitting, standing, sleeping, sex life, social life, and travelling. The items are scored from 0 to 5, 
with 0 being the best functional level and 5 being the worst functional level. A percentage is then 
derived from these responses (patient score/total possible score x 100 = %) and recorded as that 
day’s ODI. Scores are then grouped into levels of disability:

0% - 20% = minimal disability 
20% - 40% = moderate disability 
40% - 60% = severe disability 
60% - 80% = crippled 
80% - 100% = bed bound 
The ODI will be administered at baseline, on Day 1 pre-dose, at 24 hours post-dose, and at all 
post-dose visits.  
8.5 
Quality of Life 
Quality of life will be evaluated using the SF-12 form (version 2.0). The SF-12 asks 12 questions 
to measure functional health and well-being from the subject’s point of view across 8 health 
domains. Subjects provide a response to each question using a 5-point Likert scale and the 
resulting score provides a measurement of the subject’s health compared with the general 
population or compared with prior scores. The SF-12 is provided in Appendix F. 
The SF-12 will be administered at baseline, on Day 1 pre-dose, at 24 hours post-dose, and at all 
post-dose visits. The endpoint for QOL will be changes from baseline at 6 and 13 weeks 
post-dose. 
8.6 
Global Impression of Change or Improvement 
Global impression of improvement as measured by the PGI-C (Appendix G) is a single question 
survey that will be administered at baseline, on Day 1 pre-dose, at 24 hours post-dose, and at all 
post-dose visits. The endpoint for global impression of change or improvement will be changes 
from baseline at 6 and 13 weeks post-dose.  
8.7 
Appropriateness of Efficacy Measures 
The efficacy measures for this study are exploratory in nature and were chosen based on prior 
experience with the patient population. 
8.8 
Magnetic Resonance Imaging Assessment 
Magnetic resonance evaluation on the modification/shrinkage of the treated herniated disc size, 
the improvement of the stenosis of spinal canal, and the reduction of associated lateral neural 
foramen compression will be performed at Week 13, and at Months 6, 12, 18, and 24 (or early 
termination). The correlation between imaging findings and symptoms (e.g., pain score or ODI 
score) will be conducted after database lock as part of the report analysis. The herniated disc size 
will be assessed quantitatively while the compression of lateral neural formation and spinal canal 
stenosis will be evaluated qualitatively by an independent radiological reviewer.

SAFETY ASSESSMENTS 
Unless otherwise noted, the endpoint for all safety assessments is changes from baseline. 
9.1 
Vital Signs 
Vital signs (heart rate, systolic and diastolic blood pressures, respiratory rate, and body 
temperature) will be measured at screening, pre-dose and post-dose at specified times on Day 1, 
at each follow-up visit during the study, and at the end of study visit or upon discontinuation 
from the study as specified in the Schedule of Assessments (Section 11).  
9.2 
Clinical Laboratory Tests 
Samples will be obtained for the clinical laboratory tests at defined in Appendix H outlined in the 
Schedule of Assessments (Section 11) at screening, at specified times during the study. 
A certified central laboratory will be utilized to process and provide results for the clinical 
laboratory tests. The baseline laboratory test results for clinical assessment for a particular test 
will be defined as the last measurement prior to the initial dose of study drug. 
For any laboratory test value outside the reference range that the investigator considers clinically 
significant, the investigator will: 
• Repeat the test to verify the out-of-range value. 
• Follow the out-of-range value to a satisfactory clinical resolution. 
• Record as an AE any laboratory test value that (1) is confirmed and the investigator 
considers clinically significant; or (2) that requires a subject to be discontinued from the 
study; or (3) that requires a subject to receive treatment. 
9.3 
Electrocardiograms 
A standard 12-lead ECG will be obtained at screening, and at 24 hours and 13 weeks post-dose.  
Additional ECGs may be obtained if clinically indicated. Follow-up ECGs will be obtained if 
any significant abnormalities are detected after dose administration to document resolution and 
as clinically indicated. Any additional relevant data obtained by the investigator during the 
course of this study will be supplied to the Sponsor. 
9.4 
Physical Examination 
A complete physical examination, including height and weight, will be performed at screening. 
Physical examinations and weight assessments will be performed during the visits specified in 
Schedule of Assessments (Section 11). Any findings or absence of findings relative to each 
subject’s physical examination will be carefully documented in the subject’s CRF.

Anti-KTP-001 Antibodies 
Blood samples for measures of serum anti-KTP-001 antibody will be drawn pre-dose (just prior 
to administration of study drug) and at the 1-, 2-, 4- , 6-, and 13-week visits post-dose or early 
termination visit. The DSMB must be notified if antibodies are detected and the DSMB will 
advise on how to proceed. The investigators and relevant Institutional Review Board (IRB) will 
be notified about the DSMB decision. 
9.6 
Magnetic Resonance and X-ray Imaging Acquisition and Evaluation 
Imaging examination, including lumbar spine MRI and X-ray, will be acquired as outlined in the 
Schedule of Assessments (Section 11) at screening, Week 13 (±5 days), Month 6 (±1 week), 
Month 12 (±2 weeks), Month 18 (±4 weeks), and Month 24 (±4 weeks), or upon subject 
discontinuation. For subjects with contraindication for MR during the study, the alternative 
imaging modality is a lumbar spine CT. 
The MRI lumbar spine protocol includes sagittal fast (or turbo) spin echo T2-weighted, sagittal 
spin echo T1-weighted, sagittal STIR (Short Tau Inversion Recovery) images, axial fast spin 
echo T2-weighted with and without fat suppression, and axial spin echo T1-weighted images [15]. 
Axial diffusion-weighted images, axial and/or coronal Short Tau Inversion Recovery images are 
optional and upon the discretion of on-site radiologists. Unenhanced lumbar MR imaging is 
generally adequate for the imaging examination, unless contrast enhancement is specifically 
requested by the investigator or radiologist (e.g., for suspected infection). If gadolinium is 
administered, both sagittal and axial contrast-enhanced T1-weighted images with fat saturation 
will be required. If a hematoma is suspected at a post-procedure examination, an axial 
T2*-weighted image should be added.  
Both sagittal and axial images should include the area of clinical interest. Axial images should be 
obtained through the relevant lumbar disc and adjacent spine treated by chemonucleolytic 
procedure (e.g., L3-4, or L4-5 or L5-S1). Axial slice orientation should be set up in parallel with 
the treated disc and be consistent through each time point. Additional axial images may be 
placed at the level/location in which occurrence of adverse effect is suspected. Slice thickness of 
equal or less than 5.0 mm is required for sagittal images with a gap less than 1.0 mm, while slice 
thickness of equal or less than 3.0 mm for axial images without gap.  
9.6.1 
Lumbar (or lumbosacral) Spine X-ray Examination Requirements 
An anterior-posterior (AP) position and lateral neutral position views of the lumbar spine are 
required.  The flexion-extension views are optional when the patients have radicular symptom 
with the restriction of flexion.

9.6.2 
Safety Evaluation of MRI and X-ray 
Evaluation of both X-rays and MRI images will be performed by an independent radiological 
reviewer who shall be a spine imaging specialist. The X-ray safety evaluation will include 
assessment of disc height and segmental instability as defined in the halting rules in Section 5.1.3. 
The MR safety evaluation will focus on assessment of Modic changes at Week 13 according to 
the halting rules (HRs) described in Section 5.1.3. The reviewer will also assess for evidence of 
hematoma/hemorrhage, infection, discitis, and any other complications that may contribute to 
AE reporting. Qualitative information will also be collected by the independent radiological 
reviewer on the size of the herniated disc, the degree of spinal canal stenosis, and compression of 
the nerve root in the lateral neural foramen. 
Additional evaluations will be performed at Months 6, 12, 18, and 24. Lumbar spinal MR 
examination may be ordered upon discretion of the investigator if there is an emergency 
indication to conduct an examination.  
9.7 
Neurologic Examination 
A neurological examination will be performed on at screening, on Day 1 at pre-dose, 2 hours 
post-dose, 24 hours post-dose, and at all consecutive visits. The neurological examination will 
include sensory and motor examination of both lower extremities, Babinski’s sign (Appendix I), 
deep tendon reflexes, and the straight-leg raising test and femoral stretch test (Appendix D). The 
results of the neurological examination will be summarized by the investigator as unchanged, 
improved, or worsened, and documented in the CRF. Changes from baseline on this evaluation 
will be considered the neurologic safety endpoint. 
9.8 
Halting Rules 
The number of subjects with AEs defined as HRs will be described and evaluated. 
9.9 
Adverse Events 
An AE is defined as any untoward medical occurrence in a subject administered a 
pharmaceutical product during the course of a clinical investigation. An AE can therefore be any 
unfavorable and unintended sign, symptom, or disease temporally associated with the use of a 
study drug, whether or not thought to be related to the study drug. Adverse events of special 
interest (AESI) are defined in Section 9.9.3. 
Subjects will be monitored throughout the study for AEs, from the ICF signing until the last 
study visit unless the AE is considered related to the study drug/procedure, in which case the AE 
will be followed until resolution. Action taken will be categorized as none, study drug not given 
(for events occurring prior to study drug dosing), required concomitant medication, required 
procedure, or other. Event outcome at resolution or time of last follow-up will be recorded as 
event resolved, resolved with sequelae, ongoing, or death. Adverse events that are identified at 

 
Protocol Number: KTP-001-CL-101 
Amendment 4 Final 
 
 
20 October 2015 
CONFIDENTIAL 
Page 49 of 92 
the last assessment visit (or the early termination visit) as specified in the protocol must be 
recorded on the AE CRF with the status of the AE noted, and the AE must be followed until 
resolution. All events that are ongoing at this time will be recorded as ongoing on the CRF. The 
procedures specified in Section 9.9.8 are to be followed for reporting SAEs. 
9.9.1 
Assessing Severity 
The severity of an AE will be graded according to the following definitions: 
• Mild:  The subject experiences awareness of symptoms but these are easily tolerated or 
managed without specific treatment 
• Moderate:  The subject experiences discomfort enough to cause interference with usual 
activity, and/or the condition requires specific treatment 
• Severe:  The subject is incapacitated with inability to work or do usual activity, and/or the 
event requires significant treatment measures. 
Note:  it is important to distinguish between a severe AE and an SAE. Severity is a measure of 
intensity, whereas seriousness is classified by the criteria based on regulatory definitions as 
described in Section 9.9.7. An AE of severe intensity need not necessarily be classified as serious 
(e.g., a severe incapacitating migraine headache). 
9.9.2 
Assessing Causality 
The relationship of the event to the study drug should be determined by the investigator 
according to the following criteria: 
• Not related:  The event is most likely produced by other factors such as the subject’s clinical 
condition, intercurrent illness, or concomitant drugs, and does not follow a known response 
pattern to the study drug, or the temporal relationship of the event to administration of study 
drug makes a causal relationship unlikely 
• Possibly related:  The event follows a reasonable temporal sequence from the time of drug 
administration, and/or follows a known response pattern to the study drug, but could have 
been produced by other factors such as the subject's clinical condition, intercurrent illness, or 
concomitant drugs  
• Probably related:  The event follows a reasonable temporal sequence from the time of drug 
administration, and/or follows a known response pattern to the study drug, and cannot be 
reasonably explained by other factors such as the subject's clinical condition, intercurrent 
illness, or concomitant drugs.

9.9.3 
Adverse Events of Special Interest 
The following AEs will be considered an AESI that must be reported to 
 within 24 hours of 
the investigative site becoming aware of the event.       
1. MRI or X-ray findings of Modic changes, reduction of disc height, or evidence of lumbar 
instability as defined in Section 5.1.3, or any other acute MRI or X-ray changes from 
baseline images deemed significant by the central reader/spine imaging specialist. 
2. Exacerbation of back or leg pain meeting at least 1 of the following criteria: 
a) increase in average daily leg or back pain score by ≥ 3 to 6 or above on the numerical 
rating scale for at least 5 days out of a week 
b) increase in average daily pain level associated with a new onset of focal neurological 
symptoms such as numbness and/or tingling or weakness lasting for > 5 days.  
3. New onset of neurological symptoms associated with objective changes on neurological 
examination (weakness, sensory deficit, changes in deep tendon reflexes) whether or not 
associated with increase in pain level. 
4. Any deterioration of subject’s condition that in the investigator’s judgment requires: 
a) emergency MRI 
b) epidural steroid injection/selective nerve root block, facet block, or surgical 
intervention. 
Any AESI meeting seriousness criteria for SAE reporting must be reported as an SAE as defined 
in Section 9.9.8. 
9.9.4 
Following Adverse Events 
All (both serious and nonserious) AEs must be followed until they are resolved or stabilized, or 
until all attempts to determine resolution of the event are exhausted. The investigator should use 
his/her discretion in ordering additional tests as necessary to monitor the resolution of such 
events.  
9.9.5 
Discontinuation due to Adverse Events 
Any subject who experiences an AE may be withdrawn at any time from the study at the 
discretion of the investigator. Subjects withdrawn from the study due to an AE, whether serious 
or nonserious, must be followed by the investigator until the clinical outcome of the AE is 
determined. The AE(s) should be noted on the appropriate CRFs and the subject’s progress 
should be followed until the AE is resolved. The medical monitor must be notified.  
9.9.6 
Pregnancy 
Subjects must be instructed to inform the study investigator immediately if they or their female 
partner become pregnant during the study.  

 
Protocol Number: KTP-001-CL-101 
Amendment 4 Final

CONFIDENTIAL 
Page 51 of 92 
The investigator must report any pregnancy to the medical monitor within 1 business day of 
becoming aware of it and to the 
 SAE hotline per procedure. The pregnant female subject 
must be discontinued from the study. An uncomplicated pregnancy will not be considered an AE 
or SAE, but it will be documented on an AE CRF page. All pregnancies will be followed through 
birth.  
Pregnancies are captured if they occur in female subjects from the time of first signed consent for 
study participation until last visit. Female subjects with a positive pregnancy test at screening or 
pre-dose time point will be considered a screen failure.  
Any congenital abnormalities in the offspring of a subject who received study drug will be 
reported as an SAE. Any complications of pregnancy or elective termination due to a medical 
reason will be reported as an AE and follow as such. A spontaneous abortion is considered an 
SAE. The outcome of any pregnancy and the presence or absence of any congenital abnormality 
will be recorded in the source documentation and reported to the medical monitor and Sponsor.  
9.9.7 
Serious Adverse Events 
The investigator is responsible for determining whether an AE meets the definition of an SAE. 
An SAE is any AE occurring from ICF signing through final study visit, at any dose, that results 
in any of the following outcomes:  
• Death 
• A life-threatening event, defined as an event in which the subject was at risk of death at the 
time of the event 
• Inpatient hospitalization or prolongation of existing hospitalization 
• A persistent or significant disability/incapacity 
• A congenital anomaly/birth defect in a child or fetus of a subject exposed to the study drug 
• Important medical events that may not result in death, be life-threatening, or require 
hospitalization may be considered an SAE when, based upon appropriate medical judgment, 
they may jeopardize the subject and may require medical or surgical intervention to prevent 
any of the outcomes listed in this definition. Examples of such medical events include 
allergic bronchospasm requiring intensive treatment in an emergency room or at home, blood 
dyscrasias or convulsions that do not result in inpatient hospitalization, or the development of 
drug dependency or drug abuse. 
Note:  SAEs require immediate reporting to the medical monitor. See Section 9.9.8 for details.

Protocol Deviations 
A protocol deviation is defined as any intentional or unintentional change to, or noncompliance 
with, the approved protocol procedures or requirements. Deviations may result from the action or 
inaction of the subject, investigator, or site staff. Examples of deviations include, but are not 
limited to:  
• Failure to adhere to study exclusion and inclusion criteria 
• Failure to comply with dispensing or dosing requirements 
• Use of medications, food, drink, herbal remedies, or supplements that are specifically 
prohibited in the protocol 
• Missed or out-of-window visits 
• Drug dosing not administered within the time frame specified in the protocol 
• Failure to adhere to test requirements, including vital signs, laboratory tests, physical 
examinations, PK blood draws, medical history, etc either tests not done, incorrect tests done, 
or not done within the time frame specified in the protocol

• Procedural deviations such as incorrect storage of study drug, failure to update the ICF when 
new risks become known, failure to obtain IRB approvals for the protocol and ICF revisions 
At the outset of the study, a process for defining and handling protocol deviations will be 
established. This will include determining which violations will be designated “key,” requiring 
immediate notification to the medical monitor and Sponsor. The investigator is responsible for 
seeing that any known protocol deviations are recorded and handled as agreed.

12.5.1 
Vital Signs 
Descriptive statistics (mean, standard deviation [SD], minimum, maximum, and n), including 
change from baseline (pre-dose value of the relevant treatment period) for actual values of vital 
sign parameters will be presented for all scheduled time points by dose level. Additionally, the 

 
Protocol Number: KTP-001-CL-101 
Amendment 4 Final 
 
 
20 October 2015 
CONFIDENTIAL 
Page 65 of 92 
number of subjects with "substantial" increases or decreases in BP (>20 mmHg) and heart rate 
(>15 bpm) will be tabulated. 
12.5.2 
Clinical Laboratory Tests 
Descriptive statistics, including change from baseline, for the actual values of laboratory 
parameters will be presented for all scheduled time points by dose level. For subject data listings, 
abnormal values outside normal ranges will be flagged.  
If data permits, urinalysis (pH and specific gravity) will be summarized (mean, SD, median, 
minimum, maximum, and n) at each time point. 
Shift tables for laboratory parameters will be generated based on changes in National Cancer 
Institute Common Terminology Criteria for Adverse Events grade from baseline to worst 
postbaseline value. Graphical displays of key safety parameters, such as scatter plots of baseline 
versus worst postbaseline values, may be generated to better understand the study drug safety 
profile. 
12.5.3 
Concomitant Medications 
All concomitant medications collected from screening through the study period will be classified 
to preferred terms according to the World Health Organization drug dictionary and presented as 
subject data listings.

Page 66 of 92 
resolved and then reappeared while the subject was on treatment will be considered a TEAE 
(regardless of the intensity of the AE when the treatment was initiated). 
All TEAEs will be tabulated according to MedDRA by system organ class, high level terms and 
preferred terms and will include the following categories: 
• TEAEs 
• Drug-related TEAEs 
• Severe or higher TEAEs 
• Severe or higher drug-related TEAEs 
• SAEs 
Deaths and SAEs will be displayed in a subject data listing. 
12.5.8 
Imaging Data
