PROTOCOL SYNOPSIS
Sponsor:  COUR Pharmaceutical Development Company, Inc.
Study Title:  A Phase 1, First-in-Human, 2-Part, Multicenter Dose Escalation and Repeat Dose Study of the
Safety, Tolerability and Pharmacokinetics of TIMP-GLIA in Subjects with Celiac Disease
Test Product:  TIMP-GLIA 
Name of Active Ingredients: poly(lactic-co-glycolic acid), gliadin
Study Number:  TIMP-GLIA -5.001
Study Phase:  1
Study Centers:  Up to 6 centers
Study Duration: planned 3Q2017-3Q2018
Primary Objective:  
The primary objective is to assess the safety and tolerability of TIMP-GLIA when administered 
intravenously (IV) as a single dose at ascending dose levels and as a repeat dose in subjects with celiac 
disease (CD).
Secondary Objectives: 
The secondary objectives are:
!
To characterize the pharmacokinetics (PK) of TIMP-GLIA based upon concentrations of 
TIMP-GLIA in plasma over time in subjects with CD .  
!
To establish a safe and tolerable dose that may be tested during a future Phase 2 Proof of Concept 
study in subjects with CD. 
Exploratory Objective:
Study Design:
This study is a Phase 1, first-in-human (FIH), 2-part, multicenter study to assess the safety, tolerability and 
PK of TIMP-GLIA in subjects with CD .  Part A includes an accelerated titration 2+2 and traditional 3 + 3 
design with rapid dose escalationduring which successive cohorts of subjects will receive a single dose of 
TIMP-GLIA. Part B will follow as a repeat dose design using the dose level selected from Part A.
Consenting subjects will be screened within 28 days (Day -28 to -1) prior to admission to the clinical 
research unit on Day -1 for baseline assessments. 
Part A
In Part A, eligible subjects (at least 19 CD subjects) will be enrolled into escalating dose cohorts (n = 
2/cohort for 2 dose levels followed by n = 3/cohort for 5 dose levels).  TIMP-GLIA will be administered as 
a single intravenous (IV) infusion on Day 1. A staggered dosing strategy will be used in Part A.  One subject 
in a cohort will be dosed at a time and undergo medical observation in the clinic for at least 48 hours 
post-infusion. 
At least 168 hours (7 days) will elapse prior to dosing the next subject. Adverse events (AEs), vital signs, 
pulse oximetry, and electrocardiograms (ECGs) and laboratory data (serum chemistry, coagulation, 
hematology and urinalysis, cytokines) from samples obtained through at least 24 hours post dose will be 
assessed before dosing the subsequent subject(s). 
AEs will be graded according to National Cancer Institute Common Terminology Criteria for Adverse 
Events (CTCAE) Version 4.0 (Published: May 28, 2009 [v4.03: June 14, 2010]) or most current version.  If 
safety and tolerability are confirmed by the investigator, TIMP-GLIA will be administered to the next 
subject.

Dose Escalation, Part A
After all the subjects in a dose cohort complete study procedures through at least 168 hours (7 days) post 
dose the safety data will be reviewed by the Data Monitoring Committee (DMC).  Dose escalation will 
proceed only if Study Stopping Criteria (“Study Stopping Rules”) are not met. If dose-limiting toxicity 
(DLT) occurs in 1 of the subjects in a cohort in Part A, the DMC may decide to increase enrollment at the 
same dose level by 2 subjects (accelerated titration cohort) or by 3 subjects (standard 3+3). After a rate of 
DLTs has been identified for a specific dose in 3- or 6-subject cohorts, the DMC may recommend that up to 
a total of 12 subjects may be accrued at any dose level to better define the relationship between dose and 
emerging safety signals. It is also possible that the DMC could recommend an intermediate dose (lesser 
escalation) or reduced dose level (dose reduction) if warranted by the emerging safety data.  Before 
continuing to Part B, available safety data for all subjects Part A through at least 168 hours (7 days) after 
dosing will be evaluated by the DMC.
Part B
Part B will evaluate 2 doses of TIMP-GLIA administered on Days 1 and 8.  Two subjects will be enrolled 
into each of 3 cohorts at dose levels of 2, 4, and 8 mg/kg up to a maximum of 650 mg. Dose escalation will 
proceed only if Study Stopping Criteria (“Study Stopping Rules”) are not met. If dose-limiting toxicity 
(DLT) occurs in 1 of the 2 subjects in a cohort, the DMC may decide to increase enrollment at the same 
dose level by 2 subjects. (2+2 design).
Clinic Residency and Visits
Subjects in both parts of the study will remain in the clinic from admission (Part A: Day -1; Part B: Day -1 
and Day 7) through the final post-dose procedure at 48 hours (Part A: Day 3; Part B: Day 3 and Day 10) and 
will be thereafter discharged if safety parameters are acceptable to the investigator.  Subjects will return to 
the clinical research unit for follow-up assessments and will be contacted by telephone as shown in the 
Schedules of Procedures for Part A (SCHEDULES OF ASSESSMENTS
Table 1) and Part B (Table 2).
Duration of Study Period
Part A:  
Total duration of the study investigational period is up to 91 days (screening up to 28 days + 1 treatment day 
+ follow-up at Day 60 +/- 3 days). In addition, telephone follow-up by a health care practitioner is required 
after the Day 60 outpatient visit (i.e. Day 90, Day 120 and Day 180, all +/- 3 days). 
Part B: 
Total duration of the study investigational period is up to 91 days (screening up to 28 days + 2 treatment 
days, 7 days apart + follow-up at 60 +/- 3 days after last dose. In addition, telephone follow-up by a health 
care practitioner is required after the Day 60 outpatient visit (i.e. Day 90, Day 120 and Day 180, all +/- 3 
days).

higher considered to be at least possibly related to TIMP-GLIA (at the same dose level).

Any other toxicity which in the opinion of the DMC would have precluded administration of a 
second dose if this were a multi-dose study.
Safety Committee:
A Safety Committee was convened to monitor the safety of subjects up to the 2  mg/kg dose cohort.   The 
Safety Committee included the: principal Investigators (PIs) or PI’s delegate and a medical consultant with 
expertise in CD.
The role of the Safety Committee is described in prior versions of this protocol under which the 0.1 mg/kg, 
0.5 mg/kg, and 1 mg/kg doses were administered.
Data Monitoring Committee:
An independent DMC will be commissioned for this study for dose levels ≥ 2 mg/kg.  The DMC will be 
comprised of 3 physicians with expertise in immunology and/or vaccines clinical trials.  A 4th physcician 
with expertise in CD will serve as an advisor to the DMC, but in a non-voting capacity.
The sponsor medical monitor will not be a member of the DMC. The sponsor medical monitor and other 
study team members will be available to answer questions of the DMC as necessary and during Open 
Sessions of the DMC.  The medical monitor and other study team members will not participate in Close 
Sessions of the DMC. The DMC will perform ongoing safety surveillance.  The medical monitor will be 
notified of any serious adverse event (SAE) and any CTCAE Grade 2 or greater adverse event within 
24 hours of investigator’s (or designee’s) awareness of such an event.  An ad hoc DMC meeting may 
convene to evaluate safety and tolerability data to determine if it remains acceptable to continue dosing 
(within cohorts at same dose level) or to dose escalate (between cohorts) or explore lower doses.  
The DMC will evaluate the available safety data post-infusion, including but not limited to, AEs, vital 
signs, pulse oximetry, 12-lead ECGs and available laboratory results (hematology, chemistry, coagulation,
and urinalysis, cytokines). 
The following decisions may be made if stopping criteria (“Study Stopping Rules”) are not met: 

Escalate the dose as planned

Expand the dose cohort to 4 subjects (accelerated titration 2+2, Part A and Part B) or to 6 subjects
(standard 3+3, Part A)
After a rate of DLTs has been identified for a specific dose in 3- or 6-subject cohorts, the DMC may 
recommend that up to a total of 12 subjects may be accrued at any dose level to better define the 
relationship between dose and emerging the safety signals.

Decrease the dose either to a previous lower dose or to an intermediate dose


Escalate the dose to an intermediate level if warranted based on events in the previous cohort
The decision(s) of the DMC to continue dosing will be documented and provided to the investigators prior
to dosing any new subjects. 
Additionally, the DMC may meet ad hoc to determine if it remains acceptable to continue dosing.
Selection of Study Population:  
At least 23 male and female subjects 18 to 75 years of age with historical evidence of biopsy-confirmed CD
and who have negative celiac serology and quiescent CD symptomology and are otherwise healthy or with 
stable comorbidity at screening are planned to be enrolled.   
Collectively, subjects will be enrolled at up to 6 clinical research sites in the United States.  
Subjects who withdraw before receiving the first dose of study drug will be replaced. Subjects who 
withdraw after receiving study drug will be replaced at the sponsor’s discretion.  
After fully informing prospective subjects of the present study and obtaining their written informed 
consent, the investigator will perform screening tests.  Based on the results of these screening tests, the 
investigator will identify “provisional subjects” (including reserve [alternate] subjects, if available). The 
provisional subjects will be individuals who meet the inclusion criteria without meeting any of the 
exclusion criteria. Ethical and scientific aspects, the study objectives, and individual health status up to the 
selection date will also be carefully considered during the selection process.  The provisional subjects will 
be admitted to the study site on the day on Day -1, whereupon they will undergo the tests scheduled for that 
day and confirmatory assessment of study eligibility criteria. Those who are deemed eligible for enrollment 
will then be selected as enrolled subjects.

infusion.
Part B: TIMP-GLIA: 2, 4, and 8 mg/kg up to a maximum of 650 mg, administered by IV infusion.
Reference Therapy; Dose; and Mode of Administration: NA
Endpoints:[Note: Timed Procedures Are Relative To Infusion Start Time.]
Safety and Tolerability:  
Safety will be characterized by incidence, severity, and reversibility of AEs, physical examination findings, 
12-lead ECG results, arterial oxygen saturation levels by pulse oximetry, vital signs measurements, 
anti-gliadin antibody (i.e., anti-drug antibody as deamidated gliadin peptide (DGP)-specific IgG), immune 
complex detection by C1q binding and by C3a and SC5B-9 (Part B only); routine clinical laboratory test 
results (hematology, serum chemistry, coagulation, urinalysis) and other specialized laboratory test results 
(e.g., acute phase cytokines; additional vascular / thrombotic markers; mast cell activation via tryptase; 
additional complement markers, peripheral blood gliadin-specific T-cell proliferation and cytokine 
secretion). Post-dose assessment of peripheral blood T cell proliferation and cytokine secretion in response 
to ex vivo gliadin stimulation relative to baseline will be performed for the single dose groups ≥4 mg/kg in 
Part A and the for the repeat dose groups in Part B. 
The analysis of samples drawn for cytokine testing (EGF, fractalkine, GM-CSF, GRO α, IFNα, IFN-γ, 
IL-1α, IL-1 β, IL-2, IL-2 soluble receptor, IL-4, IL-5, IL-6, IL-8, IL-10, IL-12, IL-13, IL-17, IP-10, MIP1α, 
and MIP1β,  TNF-α) should be performed as follows:
The IFN-γ, IL-1 β, IL-2, IL-2 soluble receptor, IL-4, IL-5, IL-6, IL-8, IL-10, IL-12, IL-13, IL-17, IP-10, 
and TNF-α results through 24 hours post dose will be used for dose escalation decision (i.e., analyzed at 
the end of each dose cohort). This acute phase cytokine testing should be performed promptly and 
results are to be reported to the investigator as soon as possible in the event clinical symptoms occur. 
The scheduled predose and post dose samples for the other cytokines can be batched and analyzed at the 
end of the trial unless otherwise specified by the medical monitor, sponsor, or DMC or as necessary for 
compliance with the established sample stability.
Results of peripheral blood T-cell proliferation and cytokine secretion in response to ex vivo 
stimulation with gliadin will be reported at the end of the study or as otherwise specified by the sponsor, 
medical monitor, or DMC.

Tolerability will be characterized by extent of dose escalation attained without dose limiting toxicity.
Pharmacokinetics: 
Individual subject TIMP-GLIA concentrations in plasma over time will be used to derive PK parameters by 
noncompartmental analysis. The primary PK parameters are maximal observed concentration (Cmax), last 
measurable concentration (Clast), time of maximal observed concentration (Tmax), time of last measurable 
concentration (Tlast), and area under the curve from time zero and extrapolated to infinity (AUCinf) and area 
under the concentration-time curve from time zero to time of the last measurable concentration (AUClast).  
Other PK variables will be derived if feasible. The results of the PK analysis will be reported at the end of 
the study. 
Statistical Methods: 
Safety 
No formal statistical analyses will be conducted; all analyses will be descriptive. Quantitative data will be 
summarized by summary statistics and change from baseline. 
Pharmacokinetics (PK):
Individual subject TIMP-GLIA concentrations and derived PK parameters which will be summarized using 
descriptive statistics (N, mean, standard deviation (SD), coefficient of variation (CV), median, minimum, 
and maximum and geometric mean where applicable).  The PK parameters will be calculated using 
noncompartmental methods.

†Screening is the time from signing of informed consent up to but not including first administration of study drug, during which a subject is being evaluated for study eligibility. 
*All post-dose times shown relative to infusion start time. Samples for PK are to be drawn from the opposite arm from which study drug is being infused. Subjects should remain supine during dosing.
¶¶Confirm eligibility.  If the subject is found to be ineligible, record the reasons for screen failure in the source and the primary reason for screen failure in the applicable CRF.
^Weight only.
‼Inquiry regarding diet since prior visit (in-clinic or telephone)
«Full physical exam (PE) includes an assessment of general appearance, eyes, ears, nose, throat, neck (including thyroid), lymph nodes, chest (lungs)/respiratory system, cardiovascular system, abdomen 
(liver, spleen), skin, extremities, musculoskeletal, neurological system (including mental status) and any other assessment not categorized but deemed necessary by the investigator.
»Abbreviated PE includes an assessment of general appearance, skin, chest (lungs)/respiratory system, cardiovascular system, abdomen (liver, spleen). Additional assessments/full PE may be conducted 
as clinically indicated at any time.
¶Vital signs except body temperature should be performed after the subject has been supine for at least 5 minutes. Vital signs include body temperature (oral and/or tympanic measurement), blood 
pressure (SBP and DBP), pulse (beats per minute) and respiratory rate (breaths per minute).
‡Pulse oximetry will be monitored from approximately 1 hour prior to the start of study drug infusion (0 hour) through 4 hours post dose and values also recorded at times indicated.
§See in-text Table 9, Clinical Laboratory Tests, for list of specific tests.
**Women with postmenopausal status confirmed by screening follicle-stimulating hormone (FSH) result need not undergo subsequent urine pregnancy testing.
#Symptoms of anaphylactoid/anaphylactic response or infusion-related reaction (IRR) (e.g., fever, nausea, chills, rigors, hypotension, tachycardia, asthenia, headache, rash, scratchy throat, and dyspnea) 
will be followed up with additional laboratory testing for vascular / thrombotic markers (e.g., von Willebrand Factor [vWF], intercellular adhesion molecule [ICAM-1]), mast cell activation (tryptase), 
complement markers (C3a, C5a, CH50, C5-9) and for T cell proliferation and cytokine secretion in response to ex vivo gliadin stimulation for ≥ 4 mg/kg dose cohorts.  Samples are to be drawn predose 
Day 1, as needed to follow up signs/symptoms of anaphylactoid/anaphylactic response or IRR, and on Days 7 and 14.
##Samples are to be drawn predose and post dose as shown but additional samples for cytokine (& chemokine) panel are to be drawn post dose if clinically indicated (by appearance of systemic 
symptoms of anaphylaxis/anaphylactoid reaction or IRR such as fever, nausea, chills, rigors, hypotension, tachycardia, asthenia, headache, rash, scratchy throat, and dyspnea).
††ECGs in triplicate (“3X”), 1 minute apart, within 5 minutes (predrug baseline).  Scheduled ECGs at other timepoints will be performed as a single measurement (“X”). All ECGs should be performed 
after the subject has been supine for at least 5 minutes. 
†††Follow–up visit ECG only necessary if prior ECG was abnormal, clinically significant.
♥Continuous, real-time cardiac monitoring (telemetry) will be monitored starting approximately 1 hour prior to the start of study drug infusion (0 hour) through 8 hours post dose.
§§Perform phenotyping for HLA-DQ2.5 (HLA-DQA1*0501 / B1*0201) and HLA-DQ8.1 (DQA1*0301/B1*0302) if unknown OR if historical documentation not available. Sample may be taken any 
time on Day 1 from an enrolled subject. 
‡‡Anti-gliadin antibody test which serves as an anti-TIMP-GLIA antibody test (anti-drug antibody test) will be deamidated gliadin peptide (DGP)-specific IgG antibody (IgG-DGP). 
YSample should correspond to the 144 hour PK sample.
‡‡‡Additional tissue transglutaminase (tTG)-specific IgA antibody or deamidated gliadin peptide (DGP)-specific IgG antibody (IgA-tTG or IgG-DGP) serology is to be performed post dose upon 
appearance of celiac disease-related symptoms as determined by the investigator.
^^Adverse events (AEs) and concomitant medication will be collected from the time of signing of the informed consent through the final follow up.  Treatment-emergent AEs will be differentiated at time 
of first dosing. Data collected during scheduled in-clinic or telephone visits and any spontaneously reported information through the AE reporting period are to be documented in the subject’s record.
***The procedures as listed under the Study Day 14 visit should be performed as the final study procedures in the event a subject discontinues the study prematurely during the investigational period.  If 
the subject discontinues on or before Day 7, a PK sample should also be collected, if possible, provided no other PK samples were already collected on the day of discontinuation.

INTRODUCTION
1.1
Celiac Disease Overview
Celiac disease (CD) is a common immunological disorder with an estimated prevalence of 0.3 to 
2.4% among people of European ancestry (Fasano 2012). It develops in genetically predisposed 
subjects as a consequence of an abnormal T cell response to dietary prolamin protein, 
predominately gliadin, which becomes deamidated by tissue transglutaminase in the intestine. 
When deamidated gliadin -specific CD4+ T cells recognize their cognate gliadin epitope presented 
by human leukocyte antigen (HLA)-DQ/8 or HLA-DQ2 on antigen-presenting cells (APCs) in the 
lamina propria, they become activated and produce proinflammatory cytokines such as 
interferon-gamma (IFN-γ). This triggers an inflammatory cascade resulting in crypt hyperplasia 
and villous flattening characteristic of CD biopsy findings. Within the intestinal epithelium 
gliadin also triggers local production of interleukin-15 (IL-15) by enterocytes.  This IL-15 
increases expression of major histocompatibility complex (MHC) class I surface antigens (such as 
MHC class I polypeptide-related sequence A) on epithelial cells and also increases expression of 
corresponding MHC receptors (such as NKG2D) on intraepithelial T cells (i.e., CD8+αβ T cells
and γδ T cells, natural killer [NK] cells), leading to epithelial cell destruction. (Fasano 2012; Green 
2007; Leffler 2017; Mazzarela 2008; Tack 2010)
The enteropathy resulting from the T cell activation produces the chronic diarrhea, abdominal 
distension/pain, constipation, and other gastrointestinal symptoms, increased intestinal 
permeability, malabsorption, and occult gastrointestinal bleeding commonly observed in CD. 
Other manifestations might include weight loss, chronic fatigue, osteoporosis, refractory iron 
deficiency, anemia, infertility, growth failure in children, arthritis, peripheral neuropathy, 
dermatitis herpetiformis, gluten ataxia, and malignancy (Farrell 2002; Fasano 2012; Fasano 2001; 
Green 2007; Leffler 2017). In rare cases CD patients, primarily children, experience a 
life-threatening metabolic emergency termed celiac crisis, characterized by hypokalemia and 
acidosis secondary to profuse diarrhea (Baranwal 2003, Farrell 2002; Fasano 2012).  
Gluten avoidance by dietary modification, the “gluten free” diet (GFD), is the only effective 
treatment for CD as there are currently no medications that can reliably and safely prevent the 
mucosal damage caused by exposure to gluten. While the GFD has been shown to alleviate many 
of the symptoms of disease, strict adherence is difficult, and creates an additional burden on the 
day-to-day functioning of the celiac patient.  In reality, the complete elimination of gluten from the 
diet is not realistic and repeated gluten exposure, albeit unintentional or in small amounts, prevents 
complete recovery of symptoms and repair of intestinal damage (Laurin 2002; Leffler 2017; 
Rubio-Tapia 2013). 
Therapeutic approaches rendering T cells tolerant to gluten could potentially cure CD, thus 
eliminating the burdens associated with lifetime GFD and co-morbidities associated with disease 
such as cancer. Numerous therapies have been designed to induce immune tolerance in 
autoimmune diseases. However, these treatments have yielded only marginal efficacy in clinical 
trials (Kaukinen 2014).

1.2
Investigational Product: TIMP-GLIA 
Cour is developing Tolerogenic Immune Modifying Particles (TIMP) - Gliadin (“TIMP-GLIA”) 
as a first-in-class, non-immunosuppressive agent to specifically inactivate, or tolerize, 
gliadin-specific T cells, thereby abrogating and/or reversing the underlying pathology of CD. 
TIMP-GLIA may also be thought of as a noninfectious disease therapeutic vaccine or “inverse 
vaccine” (Steinman 2010).
TIMP-GLIA is comprised of gliadin extract drug substance within a negatively charged polymer 
matrix of PLGA (Poly(DL-lactide-coglycolide)) particles. TIMP deliver the gliadin antigen via
natural phagocytosis of the PLGA particles, a noninflammatory process.   This phagocytosis of the 
particles leads to antigen presentation of the gliadin by antigen presenting cells (APCs) primarily 
in the spleen and liver.  The gliadin specific T cells become anergic, or are deleted, or switch to 
T regulatory cells, thereby tolerizing the immune system to the gliadin antigen, and eliminating the 
deletirious immune cascade typically initated by the gliadin specific T cells in response to gliadin.  
TIMP-GLIA is designed and directed to specifically address and abrogate the T cell response that 
drives CD. (Getts 2015)
1.3
Nonclinical Studies
The safety and potential efficacy of TIMP-GLIA has been evaluated and supported in a robust set 
of nonclinical studies, including: a panel of in vitro nanoparticle characterization studies as 
described by the National Cancer Institute (NCI) Nanotechnology Characterization Laboratory 
(NCL) for assessing the potential toxicity and immune effects of nanoparticle therapeutics; in vivo
pharmacology studies in mice; in vivo toxicology studies in rats; and an ex vivo study of T cell 
proliferation/mitogenicity and cytokine secretion in human peripheral blood mononuclear cells
(PBMCs) (Phase 0) from both celiac and non-celiac subjects. The distribution, metabolism, and 
excretion of nanoparticles is also well-published. For detailed information refer to the 
Investigator’s Brochure for TIMP-GLIA (Edition 1, 2017 or subsequent editions as they become 
available). 
1.3.1
Pharmacology/Mechanism of Action
Splenic and liver APC populations express numerous scavenger receptors which during 
homeostasis play an important role in the recognition and recycling of dying leukocytes, red blood 
cells, and other debris on a daily basis. Targeting of and tolerogenic stimulation of APCs is crucial 
for immune tolerance induction. Importantly, these activities occur without triggering 
inflammation or breaking peripheral immune tolerance. TIMP have been designed to take 
advantage of this targeting pathway. All previously attempted immune tolerance strategies either 
using monoclonal antibodies (i.e., anti-CD3, cytotoxic T-lymphocyte antigen 4 [CTLA-4]) or 
small molecules (rapamycin) have not exploited this pathway. Specifically, the TIMP mechanism 
of action depends upon uptake of particles by APCs, particularly splenic marginal zone 
macrophages expressing scavenger receptors, such as the MAcrophage Receptor with 
COllagenous structure (MARCO), in a fashion similar to the clearance of apoptotic debris. Studies 
using particles or apoptotic cells have shown that treatment induced production of the regulatory 
cytokines interleukin-10 (IL-10) and transforming growth factor beta (TGF-β) in the spleen, as 
well as upregulation of inhibitory ligands on macrophages, such as programmed death-1 (PD-1).

Downstream events include the induction of T cell anergy and the activation of regulatory T cells. 
The overall result is abrogation of pro-inflammatory T cell activity, reduction of leukocyte 
accumulation in tissues, and importantly, disappearance of signs of disease. (Getts 2015).
1.3.2
Pharmacology
1.3.2.1
In vitro Pharmacology
The in vitro nanoparticle studies focused on hematology [blood contact] (hemolytic potential, 
platelet aggregation potential, complement activation potential, effects on coagulation), 
immunology (effect on granulocyte and macrophage colony formation, macrophage nitric oxide 
production, chemotaxis, phagocytosis, maturation of dendritic cells) and cytotoxicity (caspase 3 
and caspase 3/7 activation, MTT and LDH release) and oxidative stress (levels of glutathione, lipid 
peroxidation, reactive oxygen species) of liver cell preparations. Test concentrations of 
TIMP-GLIA in mg/mL were translated to “human equivalent doses” (HEDs) for these studies 
assuming an estimated human blood volume of 5.6 L for an average 70 kg human.
Collectively, key findings in the in vitro studies demonstrated that:

No effects of TIMP-GLIA indicative of toxicity on hemolytic potential, platelet aggregation, 
complement activation and prothrombin time (PT, extrinsic pathway) were observed at HEDs 
as high as 162 mg/kg (applied concentration 2 mg/mL). Prolonged activated partial 
thromboplastin time (aPTT, intrinsic pathway) and thrombin time (TT, common pathway) 
were observed at HED 162 mg/kg, and for TT at HED 16 mg/kg (applied concentration 0.2 
mg/kg); however, the data generated were considered to be inconclusive due to potential assay 
interference from the nanoparticles at higher concentrations.

TIMP-GLIA was not associated with overt macrophage activation, increased dendritic cell 
(DC) maturation, and was not a chemoattractant at HEDs up to 162 mg/kg. A decrease in 
expression of DC surface antigens was observed with the highest HED (162 mg/kg; applied 
concentration 2 mg/mL) ascribed to nanoparticle interference with the assay.

TIMP-GLIA was not associated with any hepatocyte toxicity at HEDs as high as 200 mg/kg. A 
finding of increased caspase 3/7 activity at HED 400 mg/kg (5 mg/mL applied concentration) 
that was attributed to assay interference by the nanoparticle. Similarly, TIMP-GLIA was not 
associated with oxidative stress (increased fluorescence response from oxidation of 
dichlorofluorescein diacetate [DCFH-DA]) at any concentration tested up to HED 400 mg/kg 
(applied concentration of 5 mg/mL). Decreased DCFH-DA fluorescence response was 
observed for HEDs of 24.8, 100, 200, and 400 mg/kg (applied concentrations of 0.31, 1.25, 2.5, 
5 mg/mL, respectively) for which particle interference with the assay was suspected.
1.3.2.2
In vivo Pharmacology (Mouse)
Primary pharmacology of TIMP GLIA was studied in mouse models that incorporated one or more 
disease characteristics associated with human CD:

Presence of activated and expanding gliadin-specific T cells and/or, 

Intestinal disease (villous atrophy, crypt hyperplasia) and/or, 

Anti-gliadin antibody development.

In these studies mice received two intravenous (IV) administrations of TIMP GLIA, 7 days apart. 
TIMP-GLIA showed the potential to induce antigen specific T cell tolerance to gliadin, whether 
treatment preceded (prevention model) or followed (treatment model) animal sensitization to 
gliadin. The optimal active dose of TIMP-GLIA observed during these studies, 125 mg/kg, is the 
HED of 10.16 mg/kg.
The key elements and outcomes of these studies are summarized in Table 3. TIMP-GLIA was not 
found to bind anti-gliadin antibody.
In addition, the mouse tissues underwent histological examination for signs of potential Type III 
hypersensitivity. Type III hypersensitivity occurs when there is accumulation of immune 
complexes (antigen-antibody complexes) that are not adequately cleared by the mononuclear 
phagocyte system and instead accumulate in the kidneys where they trigger inflammatory changes. 
Histological evidence of recent or ongoing inflammation and complement deposition was not 
evident in the TIMP-GLIA treated mice.
Taken collectively the in vivo data supports the activity of TIMP-GLIA in physiologic systems 
involved in CD without untoward biologic effects at the proposed human doses. 
1.3.2.3
Ex vivo Pharmacology (Human-Donor PBMCs)
Peripheral blood (from which PBMCs were harvested) was collected from healthy donors, donors 
with CD adhering to a GFD, and newly diagnosed celiac donors who were not adhering to a GFD. 
TIMP-GLIA incubation with PBMCs from these patients at concentrations as high as 1.25mg/mL 
(HED 100 mg/kg) did not cause T cell proliferation or pro-inflammatory cytokine production, 
indicating that the product is non-mitogenic.

Toxicology
Rats were chosen as the relevant toxicology species for TIMP-GLIA toxicology studies in 
collaboration with FDA. A non-GLP repeat dosage range finding study and the required GLP 
repeat-dose study were conducted with IV drug since this is the route intended for the Phase 1 
administration. 
1.3.3.1
Non-GLP Dose-Ranging Toxicology Study
TIMP-GLIA (Lot 36054) dosages used during the non-GLP study were 0, 10, 50, 75, 100, and 200 
mg/kg (HED: 0, 1.6, 8, 12, 16, and 32 mg/kg) and administered IV on Days 1 and 8, with the 
necropsy being on Day 15 or Day 17 depending upon tissue/blood sampling requirements. In 
summary, TIMP-GLIA produced no significant toxicological or pathological effects at 10 mg/kg 
when administered IV on Days 1 and 8.  A number of clinical pathology and microscopic 
histopathological effects were seen at dosages of > 50 mg/kg, predominately in the liver and the 
spleen.  At 200 mg/kg two animals were euthanized due to drug-related effects. (See Table 4, 
Summary of Nonclinical Observations and Clinical Risk Minimization Actions, findings shown in 
italics font.)  
Following the observation of liver pathology occurring in the high dose groups (> 50 mg/kg), a 
product purification change was implemented prior to formulating the TIMP-GLIA lot used in the 
pivotal GLP repeat dose toxicology study and all subsequent lots.  This change provided for 
greater removal of small particulates by use of a higher cut-off filter (200 nm) than employed in 
the non-GLP material (50 nm). It is noteworthy that the adverse effects observed during the 
non-GLP toxicology study at doses ≥ 50 mg/kg were not observed during the GLP toxicology 
study (summarized below).
1.3.3.2
GLP Toxicology Study
TIMP-GLIA (Lot 36092) that had undergone the product purification mentioned above was 
administered IV to rats (10/sex/group) at dosages of 0, 4, 10, 50, and 75 mg/kg (HED: 0, 0.64, 1.6, 
8, and 12 mg/kg). Infusions occurred on Days 1, 8, and 15 with the necropsy being on Day 16.  An 
additional 5 rats/sex/group underwent the same dosing regimen followed by a 28-day recovery 
period after the last dose and necropsy on Day 43. Another 5 rats/sex/group were dosed on Day 1 
and Day 8 and euthanized on Day 11 for pathology investigations and groups of 
12 rats/sex/TIMP-GLIA group plus 6 /sex/control group were dosed on Days 1 and 8 for 
measurement of TGLIA-concentrations over time for TK analysis and for cytokine measurement.  
The animals in the TK/cytokine group were euthanized after the last blood draw.
All animals survived until the scheduled necropsy and remained in good health throughout the 
course of the study. There were no significant abnormal clinical findings during the study and no 
drug-related effects were noted on body weight, body weight gain, food consumption, 
ophthalmology exams, physical exams, clinical observations, functional observational battery, 
body temperature and serum cytokine levels.  The results of the microscopic evaluation of the 
tissues obtained at necropsy of the animals terminated on Day 16 or Day 43 from each sex and 
dose group did not exhibit any pathologically significant findings. One animal treated with 75 
mg/kg and euthanized on Day 16 (rat number 5011) had a +2 liver necrosis but this was considered

by the board-certified pathologist to be within the background for Sprague Dawley rats. There was 
some evidence of local hemorrhage and inflammation at the tail vein injection site, but these were 
restricted to the immediate region of the injection (with no evidence of similar changes in any 
other tissues examined), occurred in control animals, and were considered to be typical results 
from a IV injection.
Several minor statistically significant changes were noted in the clinical pathology but were not 
judged by the study director to be drug-related as they were of insufficient magnitude or failed to 
show a relationship to dose. For example, a modest decrease was seen in total numbers of white 
blood cells (WBC) for the 75 mg/kg females at the recovery (Day 43) necropsy.  This effect was 
judged to be of minimal toxicological significance because no corresponding effect was noted at 
the end of drug treatment necropsy (Day 16) or for the 75 mg/kg males at the end of the Recovery 
necropsy. Other observations from the GLP toxicology study are noted in Table 4, Summary of
Nonclinical Observations and Clinical Risk Minimization Actions, findings shown in underline 
font.
The results of the microscopic evaluation of the tissues obtained at necropsy of the animals 
terminated on Day 16 or Day 43 from each sex and dose group did not exhibit any pathologically 
significant findings. There was some evidence of local hemorrhage and inflammation at the tail 
vein injection site, but these were restricted to the immediate region of the injection (with no 
evidence of similar changes in any other tissues examined), occurred in control animals, and were 
considered to be typical results from a IV injection.  
The no observed adverse effect level (NOAEL) from this pivotal GLP toxicology study in rats was 
determined to be 75 mg/kg.
1.3.3.3
Non-GLP Follow-Up Study to GLP Toxicology Study
Because the NOAEL (75 mg/kg; HED 12 mg/kg) occurred at the maximum dose in the GLP 
toxicology study, a small scale follow up study testing 100 mg/kg (HED 16 mg/kg) and 150 mg/kg 
(HED 24 mg/kg) using the same TIMP-GLIA (Lot 36092) was performed in rats to characterize 
the toxicity profile at higher doses.  TIMP-GLIA was administered as a slow bolus IV to rats 
(3/sex/group) at dosages of 0 (0.9% saline), 100, or 150 mg/kg (HED: 0, 16, 24 mg/kg) on Days 1 
and 5 with daily clinical observations and laboratory testing (clinical chemistry, coagulation, 
hematology) and histopathology performed on Days 4 and 8. Necropsy occurred on Day 9. 
All animals survived until euthanasia for necropsy and no abnormal clinical behaviors were 
observed.  Findings are presented in Table 4. Summary of Nonclinical Observations and Clinical 
Risk Minimization Actions. As previously observed, liver and spleen were the target organs of 
toxicity. The primary effect in the liver and spleen was infiltration of monocytes/macrophages 
which was considered to be potentially consistent with infusion of highly concentrated 
nanoparticles.
TIMP-GLIA-related effects were noted on clinical chemistry and hematology tests and generally 
were mild or moderate.  Histopathological findings in the liver included dose-dependent minimal 
to moderate mononuclear sinusoidal infiltrates and non-dose dependent minimal to mild increased 
hematopoiesis (females only) and at 150 mg/kg included minimal increased mitosis in hepatocytes

and minimal biliary hyperplasia. Findings correlated with laboratory changes. Histopathological 
findings in the spleen included dose-dependent minimal to moderate increased cellularity 
(mononuclear) in the red pulp and marginal zone and minimal to moderate increased 
hematopoiesis. Effects at 150 mg/kg included minimal to mild decreased marginal zone 
lymphocyte cellularity. Spleen effects correlated with macroscopic observation of increased 
spleen weight/enlargement and laboratory changes.
These data are consistent with prior observations and do not change safety conclusions.

Clinical Studies
To date no clinical studies of TIMP-GLIA have been conducted.
1.5
Benefit-Risk Assessment
The subjects participating in this first-in-human (FIH) study will not benefit directly from 
administration of TIMP-GLIA. Subjects may derive satisfaction from their contribution towards 
the development of a potential new treatment for CD.  
In contrast, subjects may experience adverse events (AEs) related to study drug, including 
exposure to residual trace amounts of non-particle-associated gliadin protein present within the 
reconstituted TIMP-GLIA drug product. Subjects may experience procedural complications 
related to blood draws or infusion including infusion-related reaction (IRR), and/or slight skin 
irritation from the adhesive of the electrocardiogram (ECG) electrodes. Risk of 
anaphylaxis/anaphylactoid response, characterized by rapid induction of proinflammatory 
cytokines and accompanied by headache, dyspnea, myalgias, nausea, diarrhea, erythema, 
vasodilatation, and hypotension, with subsequent life-threatening lung injury, renal failure, and 
disseminated blood clots (Suntharalingam 2006) is not probable based upon the nonclinical data 
and observations whereby gliadin exposure does not induce anaphylaxis. Notwithstanding, this 
risk cannot be entirely ruled out.
At the time of this amended protocol (Version 9), TIMP-GLIA has been given as a single infusion 
to 17 subjects with celiac disease (Part A of this study).  At the highest dose tested, approximately 
650 mg, 2 of 4 subjects experienced a moderate IRR.  For one of the subjects the infusion was 
stopped and the signs and symptoms went away immediately.  For the second subject, the infusion 
was stopped and the signs and symptoms went away immediately, and the infusion was restarted at 
a slower rate.  The subject completed the infusion without any other problems.
Signs and symptoms of IRR to TIMP-GLIA have included flushing (warm feeling or reddening of 
face, back and/or chest), rash, nausea, vomiting, back pain, low or high blood pressure, or increase 
in heart rate.  These symptoms were either mild or moderate.  All symptoms started within 2 
minutes of the infusion starting and went away very quickly when the infusion was stopped or 
interrupted.
A conservative approach is being implemented to minimize risks to subjects in the first-in-human 
(FIH) study. Safety precautions are included in the design to address all findings observed during 
nonclinical studies, even those observed in the non-GLP toxicology study that were not observed

during the GLP toxicology study. A summary of nonclinical observations and the strategy to 
mitigate the risk are summarized in Table 4.
The sponsor believes that the potential for immunoreactivity and anaphylaxis/anaphylactoid 
response by subjects in this FIH trial is low based on the following characteristics and findings for 
TIMP-GLIA:

The key components of TIMP-GLIA are PGLA polymer and gliadin.  
o
PLGA is a biodegradable (hydrolyzed to its original monomers, lactic acid and glycolic 
acid) and biocompatible component of 15 FDA-approved products. These products 
have demonstrated minimal systemic toxicity associated with PLGA for drug delivery 
or biomaterial device applications (Makadia 2011, Wang 2016).  
o
Gliadin is prolamin protein that is the same as occurs in wheat-containing foods 
ingested by healthy individuals or intentionally or unintentionally ingested by patients 
with CD, or administered during gluten challenge studies (Anderson 2005, Han 2013, 
Leffler 2013).

TIMP-GLIA decreased antigenic response during nonclinical studies.  TIMP deliver the 
gliadin antigen via natural phagocytosis of the PLGA particles, a noninflammatory process.  
Following this, nonclinical data showed treatment- induced production of the regulatory 
cytokines IL-10 and TGF-β in the spleen as well as upregulation of inhibitory ligands on 
macrophages, such as programmed death-1 (PD-1). Downstream events included the induction 
of T cell anergy and the activation of regulatory T cells (Getts 2015).

There is low expectation of an IgE-mediated (classic anaphylaxis) or IgG-mediated 
anaphylaxis in subjects treated with TIMP-GLIA. IgE-mediated anaphylaxis results from cross 
linking of protein-specific antibody bound to mast cells/basophils. This is highly unlikely 
because CD is characterized by gliadin-specific IgG, not IgE, and subjects with wheat allergy 
(which is IgE-mediated) are excluded from participation. Furthermore, there is little surface 
protein on the TIMP-GLIA particle that can bind to any gliadin-specific receptor (of IgE or 
IgG isotype), whether circulating or bound to mast cells.

In vitro studies with peripheral blood mononuclear cells from healthy donors and donors with 
celiac disease show that TIMP-GLIA does not cause T-cell proliferation or proinflammatory 
cytokine production, indicating the product is not mitogenic in either population. TIMP-GLIA 
does not interact directly with the T cell receptor (TCR) nor does it cause activation of T cells 
through binding of co-stimulation molecules expressed on T cells, platelets and other 
leukocytes. TIMP-GLIA regulates gliadin specific T cells indirectly, through antigen 
presenting cells. Therefore, TIMP-GLIA is unlikely to trigger positive co-stimulatory 
molecule activation (as observed with TGN1412) and potential for cytokine storm is very low.
Although the characteristics of TIMP-GLIA suggest a downregulation of immune response, the 
study design features and safety precautions to be implemented during the study will minimize 
medical risk to the subjects. These include:

TIMP-GLIA will be administered IV, the route generally considered to be the least likely to 
elicit an immune response compared to intradermal, subcutaneous, and inhalational routes of 
administration.


A safe starting dose was calculated taking into consideration the no observed adverse effect 
level (NOAEL) from the GLP toxicology study and the pharmacologic activity observed 
during the in vivo mouse study of DTH (see Section 2.5 Rationale for Dose Selection).

Subjects will be carefully screened for participation in the trial. Subject enrollment will be 
limited to those who are otherwise healthy or who have stable comorbidity in compliance with 
the study-specific inclusion and exclusion criteria.
o
Subjects who have a history of allergic reaction to wheat or who have a known 
hypersensitivity or allergies to the TIMP-GLIA excipients (as specified in the 
investigator brochure), or who have any other history of severe hypersensitivity or 
allergic reaction to any allergen are excluded from participation in the study. 
o
Subjects with cardiac conduction abnormalities or clinically significant laboratory test 
results (e.g., cell counts, LTs, INR) will be excluded.

This study will be conducted in clinical research units with adequate equipment and staff 
training to manage clinical emergencies (crash carts) and proximity to hospital emergency 
departments for rapid delivery of urgent care.  

Subjects will be resident in the clinic for continuous medical monitoring for 48 hours after
dosing. Prior to clinic discharge subjects will be evaluated medically including review of 
safety laboratory results from samples collected 24 hours post dose including electrolytes, 
white blood cell counts with differential, coagulation (see Table 9. Clinical Laboratory Tests) 
and occurrence of AEs including clinically significant cardiovascular (safety ECG)-, renal-, 
gastrointestinal- and CNS-related symptoms. Discharge may be delayed if the investigator 
determines additional medical follow up is necessary. Follow up assessments will be 
conducted on an outpatient basis or by telephone (see the Schedules of Procedures for Part A 
(SCHEDULES OF ASSESSMENTS

Table 1) and Part B (Table 2) and unscheduled in-clinic visits and laboratory tests may be 
performed as needed to follow-up suspected AE(s). 

Part A of the protocol TGLIA-5.001 uses a staggered dosing strategy across sites.  One subject 
in a cohort will be dosed at a time, and undergo medical observation in the clinic for at least 48
hours. Seven days (168 hours) will elapse before the next subject will be dosed at the same 
level.

For Part B, subjects within a cohort may be enrolled/dosed concurrently.

If none of the subjects in the cohort experiences a dose-limiting toxicity and stopping criteria 
(“Study Stopping Rules”) are not met based upon Data Monitoring Committee (DMC)
assessment of accumulating safety data, then escalation to the next higher dose may proceed.  
However, if 1 of the subjects at a dose level exhibits a dose-limiting toxicity, additional 
subject(s) will be dosed at the same level to clarify ambiguous safety findings. 

In Part A, when all subjects in a dose cohort complete procedures through 168 hours post dose, 
the overall safety and tolerability data (AEs, vital signs, 12-lead ECGs, clinical laboratory 
tests, cytokines) for the current cohort and available cumulative AE data from previous cohorts 
will be reviewed by the DMC who will determine the progression or termination of dosing. In 
Part B, the DMC will review all safety date from a cohort when the last subject in a cohort has 
completed procedures through 48 hours.

STUDY DESIGN AND RATIONALE
2.1
Overview of Study Design
This study is a Phase 1, FIH, 2-part, multicenter study to assess the safety, tolerability and 
pharmacokinetics (PK) of TIMP-GLIA in subjects with CD.  Part A includes an accelerated 
titration 2+2 and traditional 3 + 3 design with rapid dose escalationduring which successive 
cohorts of subjects will receive a single dose of TIMP-GLIA. Part B will follow as a repeat dose 
design using the dose level selected from Part A. (See Error! Reference source not found., 
Error! Reference source not found..)
Consenting subjects will be screened within 28 days (Day -28 to -1) prior to admission to the 
clinical research unit on Day -1 for baseline assessments. 
Part A
In Part A, eligible subjects (at least 19 subjects) will be enrolled into escalating dose cohorts (n = 
2/cohort for 2 dose levels followed by n = 3/cohort for 5 dose levels).  TIMP-GLIA will be 
administered as a single IV infusion on Day 1. A staggered dosing strategy will be used in Part A.  
One subject in a cohort will be dosed at a time and undergo medical observation in the clinic for at 
least 48 hours post-infusion. 
At least 168 hours (7 days) will elapse prior to dosing the next subject. AEs, vital signs, pulse 
oximetry, and ECGs and laboratory data (serum chemistry, coagulation, hematology and 
urinalysis, cytokines) from samples obtained through at least 24 hours post dose will be assessed 
before dosing the subsequent subject(s). 
AEs will be graded according to National Cancer Institute Common Terminology Criteria for 
Adverse Events (CTCAE) Version 4.0 (Published: May 28, 2009 [v4.03: June 14, 2010]) or most 
current version. If safety and tolerability are confirmed by the investigator, TIMP-GLIA will be 
administered to the next subject. 
Dose Escalation, Part A
After all the subjects in a dose cohort complete study procedures through at least 168 hours (7 
days) post dose the safety data  by the DMC.  Dose escalation will proceed only if Study Stopping 
Criteria (“Study Stopping Rules”) are not met. If dose-limiting toxicity occurs in 1 of the subjects
in the cohort, the DMC may decide to increase enrollment at the same dose level by 2 subjects
(accelerated titration cohort) or by 3 subjects (standard 3+3). After a rate of DLTs has been 
identified for a specific dose in 3- or 6-subject cohorts, the DMC may recommend that up to a total 
of 12 subjects may be accrued at any dose level to better define the relationship between dose and 
emerging the safety signals. It is also possible that the DMC could recommend an intermediate 
dose (lesser escalation) or reduced dose level (dose reduction) if warranted by the emerging safety 
data.  Before continuing to Part B, available safety data for all subjects in Part A through at least 
168 hours (7 days) after dosing will be evaluated by the DMC.

Part B
Part B will evaluate 2 doses of TIMP-GLIA administered on Days 1 and 8.  Two subjects will be 
enrolled into each of 3 cohorts at dose levels of 2, 4, and 8 mg/kg up to a maximum of 650 mg. 
Dose escalation will proceed only if Study Stopping Criteria (“Study Stopping Rules”) are not met. 
If dose-limiting toxicity (DLT) occurs in 1 of the 2 subjects in a cohort, the DMC may decide to 
increase enrollment at the same dose level by 2 subjects. (2+2 design).
Clinic Residency and Visits
Subjects in both parts of the study will remain in the clinic from admission (Part A: Day -1; Part B: 
Day -1 and Day 7)) through the final post-dose procedure at 48 hours (Part A: Day 3; Part B: Day 
3 and Day 10) and will be thereafter discharged if safety parameters are acceptable to the 
investigator.  Subjects will return to the clinical research unit for follow-up assessments or may be 
contacted by telephone as shown in the Schedules of Procedures for each part of study. 
Duration of Study
Part A:  Total duration of the study investigational period is up to 91 days (screening up to 28 days 
+ 1 treatment day + follow-up at Day 60 +/- 3 days).  In addition, telephone follow-up by a health 
care practitioner is required after the Day 60 outpatient visit (i.e., Day 90, Day 120, Day 180, all 
+/- 3 days).
Part B: Total duration of the study investigational period is up to 91 days (screening up to 28 days 
+ 2 treatment days, 7 days apart + follow-up at 60 +/- 3 days after last dose). In addition, telephone 
follow-up by a health care practitioner is required after the Day 60 outpatient visit (i.e., Day 90, 
Day 120, Day 180, all +/- 3 days).
2.2
Rationale for the Trial
This study is being conducted to obtain initial safety, tolerability, and pharmacokinetic 
information of single and repeat IV doses of TIMP-GLIA in adult subjects with CD.  Nonclinical 
pharmacology data with TIMP-GLIA have suggested a mechanism of action relevant to the 
pathophysiology of CD. In the mouse model of CD, TIMP-GLIA has been shown to induce T cell
tolerance by systemically targeting and controlling, gluten-reactive T cells. (See Investigator’s 
Brochure.)  Since T cell activation is considered to be the major cause of the mucosal 
inflammation, consequent antibody production, and tissue destruction observed in CD, further 
evaluation of a therapeutic agent capable of specifically inactivating, or tolerizing, these gliadin 
specific T cells is warranted. Results from the GLP repeat dose toxicology study in rats has raised
no safety concerns associated with TIMP-GLIA administration but appropriate precautions will be 
engaged to protect and evaluate subject safety after single and repeat (2) doses of TIMP-GLIA.
2.3
Rationale for the Trial Design
This FIH clinical study in patients with stable CD will consist of 2 parts.  Part A is a traditional, 
open-label, single ascending dose (SAD) study with staggered dosing.  The dose escalation and 
cohort size in Part A are based upon accepted methodology for phase I studies (Le Tourneau 2009, 
Rubinstein 2003). In Part A, an accelerated titration (2+2) model will be followed at the lowest

doses followed by the standard 3+3 model at higher doses. In Part B, an accelerated titration (2+2) 
model will be followed.  See also Figure 1. Schematic of Planned Dosing in Subjects With Celiac 
Disease, Part A and Part B  and further description in Section 2.1, Overview of Study Design.)
In Part A, this design will allow the study proceed more quickly through the lowest doses at which 
little or no effect is anticipated to be observed.  Cohort size increases to 3 at the doses for which 
pharmacologic or clinical effect would be more likely, based upon the nonclinical studies.  The 
cohort size in the accelerated titration phase of 2 subjects and an additional 2 subjects if warranted, 
and the cohort size in the standard 3+3 phase of at least 3 and up to 6 subjects if warranted, have 
been employed to facilitate a reasonable rate of accrual of subjects and to confirm ambiguous 
safety or tolerability findings.  In Part B, the accelerated model allows the study to proceed at the 
lower doses at which little or no affect is expected.
Subject safety is prioritized at all doses.
Should a dose limiting toxicity (DLT) occur in one subject, an additional cohort will be dosed at 
the same dose level to follow up ambiguous safety observations, provided no stopping criteria 
(“Study Stopping Rules”) have been met according to the DMC (see Section 7.2, Safety 
Committee). Stopping criteria have been set in accordance with traditional phase I study 
methodology. Decisions to advance or modify dose level(s) within Part A will be guided by 
evaluation of accumulating safety and tolerability data by the DMC.  
Part B will be a repeat-dose study with 2 subjects who will receive the first infusion on Day 1 and 
the second infusion on Day 8. If a dose-limiting toxicity occurs in 1 of the 2 subjects in Part B, the 
DMC may decide to enroll an additional 2 subjects at the same dose to confirm ambiguous safety 
or tolerability findings. Repeat dosing will provide support for safe and tolerable dosing using the 
2-dose regimen to be investigated in the future proof-of-concept (POC) clinical trial.  
The 48-hour minimum observation period prior to discharge was selected because the major 
potential toxicities are anticipated to emerge within this duration. 
The Day 60 (+/- 3 days) outpatient follow-up visit of the investigational period and Day 180
(+/- 3 days) telephone contact follow up after last dose will allow sufficient time to capture 
potential delayed-onset AEs and evaluate the potential for antibody response to TIMP-GLIA.
2.4
Rationale for the Subject Population 
The rationale for going directly into the subject population of interest (CD subjects) in this 
first-in-human (FIH) study is to allow early assessment of any disease-specific safety issues and is 
supported as follows:

CD is characterized by an immune reaction to the gliadin component of gluten. Only celiac 
patients have gliadin-specific T cells. (Anderson 2000, Han 2013, Christophersen 2016) As the 
mechanism of action of TIMP-GLIA involves gliadin-specific T cells, the potential drug 
effects on T cells cannot be measured in healthy individuals, only those reactive to gluten. In 
other words, healthy individuals are tolerant to gluten and as such data obtained from studies 
using healthy subjects may provide incomplete information/conclusions regarding

TIMP-GLIA safety.  Thus, subjects with CD provide the most likely opportunity to determine 
any potential adverse safety signal in the presence of gliadin-specific T cells.

CD patients on a GFD provide the best opportunity to measure PK of TIMP-GLIA without the 
potential for confounding background levels of gliadin.

Restricting enrollment to subjects with negative celiac serology and quiescent CD
symptomology (clinically inactive) who are otherwise healthy or with stable comorbidity will 
minimize the potential to confound the interpretation of safety data. 

Excluding subjects with history of immunoglobulin E (IgE)-mediated reaction and/or 
anaphylaxis to wheat (i.e., “wheat allergy”), barley or rye or a known history of 
hypersensitivity or allergies or severe allergic reaction to any other allergens (medications, 
food or environmental) is a safety precaution.
2.5
Rationale for Dose Selection
The determination of the planned starting dose of this study and the dose range to be tested is 
consistent with the principles set out in FDA 2005 Guidance for Industry Estimating the Maximum 
Safe Starting Dose in Initial Clinical Trials for Therapeutics in Adult Healthy Volunteers (FDA 
July 2005) and FDA 2011 Guidance for Industry Clinical Considerations for Therapeutic Cancer 
Vaccines (FDA October 2011).  The rationale for determining a safe starting dose for the FIH 
study takes a multi-faceted approach considering all of the data and experience obtained during 
nonclinical studies, summarized previously. The maximum recommended starting dose (MRSD) 
was determined conservatively, taking into account both the NOAEL in rat GLP toxicology study
and the pharmacologically active doses (PAD) causing partial inhibition and full inhibition of ear 
swelling in a mouse DTH model pharmacology study; to these a ten-fold safety margin was 
applied. 
The findings from the in vivo nonclinical pharmacology and toxicology studies of TIMP-GLIA 
have provided reasonable assurance that there are no undue risks for the first administration of 
TIMP-GLIA to humans at the dose levels proposed in this study.
2.5.1
TIMP-GLIA Toxicology and the NOAEL
The GLP repeat-dose toxicology study of TIMP-GLIA is required by FDA to assess toxicity in the 
appropriate animal model (rat). This GLP study also utilized TIMP-GLIA formulation that 
underwent the additional purification step that is applicable to the clinical lots.  For these reasons,
the NOAEL has been identified from the GLP toxicology data for calculation of the maximum 
recommended starting dose (MRSDtox) for the FIH trial. 
Upon evaluation of the GLP toxicology data (Section 1.3.3.2, GLP Toxicology Study and 
Investigator Brochure, Edition 1), the study director identified a NOAEL of 75 mg/kg.
Using both standard conversions (by body surface area and body weight) described in the FDA 
2005 Guidance for Industry, the MRSDtox based upon NOAEL in rat is calculated as shown in 
Table 5.

2.5.2
TIMP-GLIA Pharmacologically Active Dose 
TIMP-GLIA pharmacologic effect was evaluated in vivo using a mouse model of DTH.  Mice
were treated with two infusions of TIMP-GLIA after sensitization with gliadin (Table 3). 
Pharmacologic activity was initially observable at 12.5 mg/kg as partial inhibition of 
gliadin-specific inflammation (ear swelling) comparted to non-treated controls (“subtherapeutic 
response”). Full inhibition (“therapeutic response”) was observed at 125 mg/kg compared to 
non-treated controls.   This is the relevant dose range of TIMP-GLIA pharmacologic activity 
(pharmacological active dose, PAD).
Applying the standard conversions (by body surface area or body weight) described in the FDA 
2005 Guidance for Industry to the TIMP-GLIA doses, MRSDPAD based upon full or partial 
inhibition of DTH response is calculated as shown in Table 6.

In addition to the in vivo toxicology and DTH data, TIMP-GLIA was studied for its potential to 
induce T cell proliferation / mitogenicity in a Phase 0 ex vivo study using peripheral blood 
mononuclear cells (PBMCs) from human donors: healthy subjects, celiac subjects adhering to a 
GFD, and subjects newly diagnosed with CD who were not yet adhering to a GFD.  Subjects with 
CD adhering to a GFD are most representative of the subjects to be enrolled in the Phase 1 clinical 
study. 
T cell mitogenicity was not observed from samples collected from any of the subject cohorts up to 
the maximum concentration studied of 1.25 mg/mL (HED  ~100 mg/kg assuming a 70 kg human 
with 5.6 L of blood volume using the conversion method described in NCL in vitro study 
protocols).  In addition, no immune cytokine activation was observed in the samples from the 
human donors.  Based upon this result, immune activation may only be anticipated to occur at 
some level greater than ~100 mg/kg.  
2.5.3
TIMP-GLIA Maximum Recommended Starting Dose 
Applying the most conservative approach for the FIH clinical study, a starting dose of 0.1 mg/kg 
followed by 0.5 mg/kg will be explored in 2 subjects each via an accelerated titration 2 + 2
schedule.  This is followed by dosing cohorts of 3 subjects according to a standard 3+3 escalation 
schedule beginning with a dose of 1 mg/kg.   The larger cohorts are employed at 1 mg/kg when 
pharmacologic effects are more likely to be observable.

Pharmacokinetics Endpoints 
The PK of TIMP-GLIA will be derived from the plasma TIMP-GLIA concentration – time curve
by noncompartmental analysis.  The primary PK parameters are maximal observed concentration 
(Cmax), last measurable concentration (Clast), time of maximal observed concentration (Tmax), and 
area under the curve from time zero and extrapolated to infinity (AUCinf) and area under the 
concentration-time curve from time zero to time of the last measurable concentration (AUClast).  
Other PK variables will be derived if feasible. The results of the PK evaluation will be reported at 
the end of the study.
Establishment of a maximal feasible dose (MFD) to administer during the future proof-of-concept 
study in CD patients is another secondary endpoint.

STUDY POPULATION
At least 23 male and female subjects 18 to 75 years of age with historical evidence of 
biopsy-confirmed CD and who have negative celiac serology and quiescent CD symptomology 
and are otherwise healthy or with stable comorbidity at screening are planned to be enrolled. 
Subjects will be enrolled at up to 6 clinical research sites in the United States.  
Subjects who withdraw before receiving the first dose of study drug will be replaced. Subjects who 
withdraw after receiving study drug will be replaced at the sponsor’s discretion.  
After fully informing prospective subjects of the present study and obtaining their written 
informed consent, the investigator will perform screening tests.  Based on the results of these 
screening tests, the investigator will identify “provisional subjects” (including reserve 
[“alternate”] subjects, if available). The provisional subjects will be individuals who meet the 
inclusion criteria without meeting any of the exclusion criteria. Ethical and scientific aspects, the 
study objectives, and individual health status up to the selection date will also be carefully 
considered during the selection process.  The provisional subjects, if available, will be admitted to 
the study site on the day on Day -1, whereupon they will undergo the tests scheduled for that day 
and confirmatory assessment of study eligibility criteria. Those who are deemed eligible for 
enrollment will then be selected as enrolled subjects (including reserve subjects).
There will be no waivers or exemptions (a prospective approved deviation) from the inclusion or 
exclusion criteria.

6.2.2
Storage and Handling
TIMP-GLIA vials should be stored at 2oC to 8oC (36o to 46o F) and protected from light in a secure, 
temperature-monitored, limited access location. All sponsor-supplied drugs must be stored under 
the conditions specified on the label, and remain in the original container until dispensed. A daily 
temperature log of each drug storage area must be maintained and temperature excursions 
documented. Detailed information on the storage conditions following reconstitution and dilution 
of study drug are provided in the Pharmacy Manual.
Current ICH GCP Guidelines require the investigator to ensure that study drug deliveries from the 
sponsor are received by a responsible person (e.g. pharmacist), and

that such deliveries are recorded;

that study drug is handled and stored safely and properly in a pharmacy or other locked and 
secure storage facility under controlled storage conditions, accessible only to those authorized 
by the investigator to dispense these test drugs;

that study drug is only dispensed to study subjects in accordance with the protocol;

that any unused study drug is returned to the sponsor or standard procedures for the alternative 
disposition of unused study drug are followed.
6.2.3
Inventory and Accountability 
Study drug will be provided to the clinical site by Cour or its designee. 
Drug inventory and accountability records for the study drugs will be kept by the investigator or 
designee (e.g., pharmacist).
The investigator or designee will acknowledge date of receipt and verify condition/quantities by 
signing the packing list/shipping form in the shipment. In addition, the date and time and quantity 
of study material prepared for/dispensed to each subject and by whom must be recorded on the 
drug accountability log.  The required accountability for this study is vial count. Date/time vial is 
reconstituted and subject number should be written on the vial label to facilitate accountability. All 
used and unused containers are to be stored until accountability procedures are completed.
At the conclusion or termination of this study, the investigator or designee is to reconcile records 
of study drug delivery, preparation, dispensation, usage, and final disposition (destroyed or 
returned) to ensure completeness of the Drug Accountability Log and agreement with other 
clinical study records. Any discrepancies must be accounted for, including reasons for departure 
from the expected administration regimen and corresponding vial quantities. Appropriate forms 
and records must be signed by the person responsible.
Used or unused study drug may be destroyed at the study site according to standard institutional
procedures after drug accountability has been conducted by the sponsor or representative, only if 
agreed upon by the sponsor. A copy of the standard institutional procedure for destroying 
investigational drugs will be provided to the sponsor or designee upon request. Unused study drug 
not destroyed at the site must be returned to the sponsor or designee at the end of the study or upon

Method of Assigning Subjects to Treatment Groups
Enrollment will occur competitively across initiated clinical sites. Prior to enrollment of an 
eligible subject, the investigator or designee is to request enrollment in writing to the sponsor’s 
designee who will provide dose assignment and confirm subject identification (ID) number as 
appropriate and who will track subject enrollment/dose date/completion/discontinuation and 
screen failures.  The designee will also coordinate dose scheduling such that dosing of individual 
subjects within a cohort (Part A and Part B) is compliant with protocol requirments.
Subjects meeting eligibility criteria who are enrolled in this study will receive open-label 
TIMP-GLIA.  
The 9-digit subject ID number will be as follows:
3-digit country code-3-digit site number-3-digit sequential number
Once a subject ID number has been assigned to a subject it will not be reused for another subject.   
If a subject withdraws prematurely from the study and is replaced, a new subject ID number will be 
assigned to the replacement subject.  The replacement subject will receive the same treatment as 
the person being replaced.

TREATMENT ADMINISTRATION
7.1
Dose and Regimen
Aseptic technique must be used for the preparation and administration of TIMP-GLIA.  Detailed 
instruction will be provided in the Pharmacy Manual.
TIMP-GLIA will be administered once as an IV infusion by a controlled infusion device. The 
planned doses will range as shown in Error! Reference source not found.. The dose to be 
investigated in Part B will be the maximum tolerable dose reached in Part A.
The lyophilized drug product will be reconstituted in the vial with SWI and then further diluted for 
infusion according to the Pharmacy Manual.  The preparation of the dose will be confirmed by a 
second member of the study site staff.
Dosing will occur on Day 1 in Part A and on Day 1 and Day 8 in Part B (7 days apart). Subjects 
should remain supine during dosing.
As a safety precaution, venous access should be maintained for emergency use for 24 hours after 
dosing.
On dosing days, subjects will receive the assigned study drug after the subject has fasted from food 
and beverage approximately 2 hours prior to infusion start and 1 hour after infusion end. Water 
may be provided ad libidum.
For Part B, TIMP-GLIA should be administered at the following escalating rates:

20 mL per hour for 15 minutes, then

40 mL per hour for the next 15 minutes, then

80 mL per hour for the duration of the infusion 
7.2
Safety Committee (Dose Levels < 2 mg/kg)
A Safety Committee was convened to monitor the safety of subjects up to the 2  mg/kg dose 
cohort..  The Safety Committee included the: principal Investigator(s) (PIs) or PI(s)’s delegate(s)
and a medical consultant with expertise in CD. 
The role of the Safety Committee is described in prior versions of this protocol under which the 0.1 
mg/kg, 0.5 mg/kg, and 1 mg/kg doses were administered.
7.3
Data Monitoring Committee (Dose Levels ≥2 mg/kg)
An independent DMC will be commissioned for this study for dose levels ≥2 mg/kg.  The DMC 
will be comprised of 3 physicians with expertise in immunology and/or vaccines clinical trials.  A

The sponsor medical monitor will not be a member of the DMC. The sponsor medical monitor and 
other study team members will be available to answer questions of the DMC as necessary and 
during Open Sessions of the DMC.  The medical monitor and other study team members will not 
participate in Closed Sessions of the DMC. The DMC will convene when each dose cohort is 
completed to determine if it remains acceptable to continue dosing subjects. The DMC may also 
convene ad hoc to address emerging safety concerns. The DMC will evaluate the available safety 
data post-infusion, including but not limited to, AEs, vital signs, pulse oximetry, 12-lead ECGs 
and available laboratory results (e.g., hematology, chemistry, coagulation, and urinalysis, 
cytokines) in the context of the established Study Stopping Rules. 
The following decisions may be made if stopping criteria are not met: 

Escalate the dose as planned

Expand the dose cohort to 2 subjects (accelerated titration 2 + 2, Part A and Part B) or 6 
subjects (standard 3+3, Part A)
After a rate of DLTs has been identified for a specific dose in 3- or 6-subject cohorts, the DMC
may recommend that up to a total of 12 subjects may be accrued at any dose level to better 
define the relationship between dose and emerging the safety signals.

Decrease the dose either to a previous lower dose or to an intermediate dose

Escalate the dose to an intermediate level if warranted based on events in the previous cohort
The decision(s) of the DMC to continue dosing will be documented and provided to the 
investigators prior to dosing any new subjects. 
Additionally, the DMC may meet ad hoc to determine if it remains acceptable to continue dosing.
The medical monitor is to be notified of any serious adverse event (SAE) and any CTCAE Grade 2 
or greater toxicity within 24 hours of investigator’s (or designee’s) awareness of such an event. 
7.4
Progression or Termination of Dosing
Dosed subjects will remain under medical supervision in the clinic for 48 hours after dosing.
Emerging safety data will be evaluated by the DMC against the Study Stopping Rules (Section 
7.4.6) and defined dose limiting toxicity (Section 7.4.5).
7.4.1
Premature Termination of An Individual Subject’s Infusion
If a subject develops signs and symptoms of IRR (dyspnea, generalized cutaneous reactions, 
tachypnea, hypoxia, tachycardia, or if the subject experiences a decrease in blood pressure the 
investigator should stop the infusion for a minimum of 5 minutes or until signs and symptoms 
subside.  Depending upon the severity of the signs and symptoms, and at the investigator and 
subject discretion, the infusion may be restarted as follows:
o
Restart the infusion at 25% of original rate for 15 minutes
o
If subject tolerates the reduced rate, increase to 50% of original rate for another 15 
minutes, then increase to the original rate until infusion is complete

Infusion will be permanently discontinued if the subject develops clinical signs and symptoms of 
Grade 3 or 4 IRR or anaphylaxis/ anaphylactoid reaction (any combination of nausea, vomiting, 
myalgia, rigors, fever [oral temperature ≥2oC above baseline]) and/or clinically significant 
dyspnea, generalized cutaneous reactions, tachypnea (doubling of baseline respiratory rate, 
resting), hypoxia (oxygen saturation < 90% on room air), tachycardia (resting heart rate 
> 120 bpm), or if the subject experiences a decrease in blood pressure that requires therapeutic 
intervention or other SAE, or if the subject experiences any other clinically significant AE which, 
in the opinion of the investigator, warrants termination of infusion.
7.4.2
Dosing Subjects Within A Dose Level (Within A Cohort)
Part A
During Part A (dose escalation), 1 subject will be dosed at a time followed by in-clinic observation 
for at least 48 hours. At least 168 hours (7 days) will elapse prior to dosing the next subject at the 
same level. This staggering is to provide sufficient time for acute adverse effects to emerge before 
additional subjects are exposed.
Dosing additional subjects in a cohort will be stopped if 1 of the subjects at a dose level exhibits a 
dose-limiting toxicity (DLT) or should any subjects in the current dose cohort or any previously 
dosed subject (in any dose group) develop clinical signs and symptoms of Grade 3 or 4 IRR or 
anaphylaxis/anaphylactoid reaction (any combination of nausea, vomiting, myalgia, rigors, fever 
[oral temperature ≥2oC above baseline]) and/or clinically significant dyspnea, generalized 
cutaneous reactions, tachypnea (doubling of baseline respiratory rate, resting), hypoxia (oxygen 
saturation < 90% on room air), tachycardia (resting heart rate > 120 bpm), or a decrease in blood 
pressure that requires therapeutic intervention or other SAE.
Dosing of additional subjects in a cohort will also be stopped upon the occurrence of 2 or more of 
the same CTCAE Grade 3 toxicity (among total subjects dosed ) or the first occurrence of a
CTCAE Grade 4 or Grade 5 toxicity, irrespective of relationship to study drug.
In this situation, the DMC will evaluate the cause of the abnormalities and whether they represent 
a drug-related safety concern, warrant implementation of additional safety precautions, dose 
groups, or other protocol changes, or justify study termination (i.e., Study Stopping Rules
fulfilled). 
If 1 of the subjects at a dose level exhibits dose-limiting toxicity and the DMC confirms the study 
will continue, an additional 2 subjects (accelerated titration 2+2, Part A) or 3 subjects (standard 
3+3, Part A) will be dosed at the same level, staggered appropriately, so that a total of 4 subjects 
(accelerated titration 2+2) or 6 subjects (standard 3+3) will receive the same dose. (See Error! 
Reference source not found. .) After a rate of DLTs has been identified for a specific dose in 3- or 
6-subject cohorts, the DMC may recommend that up to a total of 12 subjects may be accrued to 
better define the relationship between dose and emerging safety signals.
When all subjects in a dose level cohort complete procedures through 168 hours (7 days) post 
dose, the overall safety and tolerability data (AEs, vital signs, 12-lead ECGs, clinical laboratory 
tests, cytokines) and available cumulative AE data from previous cohorts will be reviewed by the 
DMC who will determine the progression or termination of dosing to the next dose level.

Part B
During Part B (repeat dose), subjects will receive 2 doses followed by in-clinic observation for at 
least 48 hours after each dose. At least 48 hours (2 days) will elapse after the second dose and 
safety confirmed before subjects in next higher dose cohort can be dosed. If dose-limiting toxicity 
occurs in 1 of the 2 subjects in Part B, the DMC may decide to increase enrollment at the same 
dose level by 2 subjects (n=4). 
7.4.3
Dose Escalation – Dosing Subjects At the Next Dose Level
After all subjects at a dose level have completed study procedures through Day 8 (168 hours
[7 days] post dose), the overall safety and tolerability of the dose will be determined by DMC
evaluation of the safety data (AEs, vital signs, 12-lead ECGs, clinical laboratory tests) for the 
current cohort and available cumulative AE data from previous cohorts against the Study Stopping 
Rules. 
The DMC will decide whether dose escalation and enrollment of the next dose group should occur. 
If none of the subjects in the cohort experiences a DLT and stopping criteria are not met based 
upon DMC assessment of accumulating safety data, then escalation to the next higher dose may 
proceed.
If 2 or more subjects experience DLT(s) at a dose level, the prior dose level will be defined as the 
maximum tolerable dose (MTD) . The highest dose level that did not cause unacceptable side 
effects will be considered the MTD.
7.4.4
Dose Reduction
Depending upon emerging safety data, the DMC may recommend dosing a cohort of 2 subjects
(accelerated titration 2 + 2, Part A and Part B) or 3 subjects (standard 3+3, Part A) at a dose lower 
than the planned level to better identify the maximum tolerable dose of TIMP-GLIA.
7.4.5
Dose Limiting Toxicity Definition
DLT is defined to be an AE or set of AEs that prevents further administration of the agent at that 
dose level.  For this study DLT is defined as occurrence of:

A CTCAE Version 4.0 Grade 3 or higher that is at least possibly related to TIMP-GLIA; or

Treatment Compliance
The subject will be administered study drug in the clinical research unit by qualified staff.  The 
date and infusion start and stop time and total volume infused are to be recorded. In the event of an 
interruption of an infusion, the stop/restart times of the interruption should also be documented as 
well as reason/circumstances. Compliance will be evaluated through review of study drug 
dispensing and administration records. 
7.6
Emergency Procedures and Management of Overdose
In the event of adverse clinical responses to TIMP-GLIA infusion, interventions should be guided 
by the subject’s symptoms and condition.  Acute interventions for anaphylaxis/anaphylactoid 
reaction may include, but are not limited to, supplemental oxygen, endotracheal intubation and 
mechanical ventilatory support, supportive IV fluid administration, and/or Advance Cardiac Life 
Support (ACLS) therapies. If appropriate, transfer to an acute care hospital facility should be 
performed.
An overdose is defined as a known deliberate or accidental administration of TIMP-GLIA to a 
study subject at a dose above that which was assigned to the subject according to the study 
protocol. 
There are no defined emergency procedures for an overdose of study drug. Treatment should be 
guided by symptoms. 
All cases of overdose and any AE resulting from the overdose are to be documented in the source.
Any case of overdose should be reported to the sponsor as a “special situation” (see protocol 
section 8.6.7 Collection and Reporting of Special Situations). Serious AEs arising from overdose 
are to be reported accordingly (see 8.6.2 Serious Adverse Events and 8.6.6 Collection and 
Reporting of Serious Adverse Events).

7.7
Restrictions During the Study/Treatment Conditions
Subject habits will be assessed at screening for study eligibility. Compliance with study 
restrictions with respect to eligibility criteria is to be confirmed at Day 1/prior to first dosing and 
thereafter compliance with study restrictions are to be assessed at each visit, including telephone 
“visits”.
7.7.1
Clinic Residency and Clinic Visits
Subjects participating in Parts A and B will report to the clinical research unit one day (Day-1) 
before the first dose and will remain residential in the clinic until completion of study procedures 
on Day 3. If, in the opinion of the investigator, a subject’s condition warrants longer medical 
observation, clinic discharge may be delayed. Subjects participating in Part B will return for clinic 
admission one day (Day 7) prior to the second dose and will remain residential until completion of 
study procedures on Day 10.  Clinic discharge may be delayed if extended medical observation is 
indicated.
All subjects will report to the clinic for scheduled outpatient visits, which are indicated in the 
Schedules of Procedures for Part A (SCHEDULES OF ASSESSMENTS
Table 1) and Part B (Table 2). Unscheduled clinic visits to follow up suspected AEs or to permit 
sample collection may also be arranged at the discretion of the investigator. If necessary 
arrangements can be made, visits to remote sample collection laboratories to permit sample 
collection may be allowed, if necessary to avoid missed procedures or to facilitate AE follow-up, 
with prior discussion between the sponsor and investigator.
Follow up via telephone contact is to be arranged according to the Schedules of Procedures for 
Part A (SCHEDULES OF ASSESSMENTS
Table 1) and Part B (Table 2) and as needed by the subject or clinic staff to ensure safety, data 
completeness, and logistics for future study activities.
7.7.2
Dietary and Fluid Restrictions
Consumption of alcohol will be prohibited from 24 hours prior to clinic admission until discharge 
from the clinic. To avoid false-positive results from the drug screen, food and drinks containing 
poppy seeds will not be allowed during the study. To facilitate compliance subjects should be 
reminded that testing for the presence of drugs of abuse and alcohol will be performed at Screening 
and each clinic admission (check-in).
Standardized gluten-free meals (breakfast, lunch, dinner) and non-alcoholic beverages will be 
served at consistent times relative to dosing and performance of study procedures while subjects 
are confined in the clinic. Meals must not interfere with any study procedures. The menu and 
nutritional information is to be archived in the study file.
When not confined, subjects are to maintain a GFD from the time of screening through the final 
study procedure.

EVALUATIONS AND ASSESSMENTS
8.1
Demographics and Baseline Characteristics
Demographics and baseline characteristics will be collected at Screening. This will include sex, 
race, ethnicity, and date of birth, height, weight, and calculated BMI. Weight may be recorded at 
additional timepoints.
Height (m) and weight (kg) are to be recorded while the subject is wearing indoor clothing with 
shoes off. Body mass index (BMI) will be calculated as weight (kg)/ height (m)2. 
8.2
Medical History, and Medication History
A complete medical history, medication history and history of smoking/tobacco and alcohol habits 
will be recorded at Screening and reviewed for any changes at clinic check in (Day 1) to ensure 
compliance with the study eligibility criteria.
The medication history includes use of any prescribed or nonprescription medications, 
medications given as part of any surgical procedure, and dietary supplements (including vitamins, 
minerals, natural and herbal remedies) taken at least once in the 6 months before Screening.  
The medical history should include clinically significant medical or surgical history ongoing at 
baseline or with onset in the previous 2 years.  Subjects will be asked about previous diseases and 
conditions to allow thorough evaluation of the study eligibility criteria.  Medical history 
assessment will include but is not limited to questions about gastrointestinal disease, malignancies, 
diseases associated with immunosuppression, allergies and hypersensitivity reactions, hepatitis, 
HIV, and infectious diseases requiring systemic treatment within the last 2 weeks and about any 
participation in other clinical trials.
8.3
Diet History (Subjects With Celiac Disease)
A dietary history will be obtained from each subject via interview/questionnaire and adherence to 
a GFD is to be confirmed at Screening. Because the CD serology titers (tTG, DGP) are likely to be 
positive if subjects have not been following a GFD for at least 6 months or if they have recently 
(within at least 10 days) experienced gluten exposure, the outcome of the diet history discussion 
may prevent unnecessary blood tests.  Performance of the CD serology may proceed at the 
discretion of the investigator if diet history is not completely known and there is a reasonable 
possibility for negative or weak positive titers. 
8.4
Concomitant Medications
All concomitant medications from the time of the first study drug dose through the last study visit
will be recorded.  Medication used prior to first dosing will be recorded as medication history as in 
Section 8.2 Medical History, and Medication History).
Concomitant medication includes all medicinal products other than TIMP-GLIA including 
prescribed or nonprescription medications, medications given as part of any surgical procedure, 
and dietary supplements (including vitamins, minerals, natural and herbal remedies). If a subject

discloses participation in another interventional clinical trial during the course of the current study, 
the investigational product administered to the subject will be recorded as a concomitant 
medication.
Subjects must be instructed not to take any medications, including over-the-counter medications, 
without first consulting with the investigator. Only stable medication to manage underlying 
comorbidity, stable hormone replacement therapy, or contraceptives identified at Screening and 
approved by the investigator and sponsor may continue during the study. Occasional use of 
acetaminophen (no more than 2 g/day) may be allowed but non-medication treatment such as a 
cold compress should be tried before over-the-counter analgesic use. 
Any concomitant medications deemed necessary for the management of an AE during the study 
may be given at the discretion of the investigator. It is the responsibility of the investigator to 
ensure that the details regarding the medication are recorded in full (e.g., product name [with 
description if necessary], dose/quantity, method of administration, frequency, usage start/stop 
date, usage start/stop time if applicable, reason). Usage of any concomitant medication other than 
acetaminophen may result in withdrawal of the subject unless, after discussion between the 
investigator and sponsor’s medical monitor, it is concluded that the medication is not expected to 
influence the outcome of the study.
Concomitant medications will be coded using the World Health Organization (WHO) Drug 
Dictionary (WHO Drug).

Safety Assessment
8.5.1
Physical Examination 
Physical examination will be performed according to the Schedules of Procedures for Part A 
(SCHEDULES OF ASSESSMENTS
Table 1) and Part B (Table 2).
A full physical examination (PE) will consist of an assessment of general appearance; eyes; ears, 
nose, throat; cardiovascular system; chest (lungs)/respiratory system; abdomen (liver, spleen);
skin; extremities; musculoskeletal system; neurological system, including mental status; 
neck/thyroid/lymph nodes; and other. The abbreviated PE will include assessment of general 
appearance; skin; chest (lungs)/respiratory system; cardiovascular system; abdomen (liver, 
spleen). 
Any abnormal finding observed during the screening visit must be assessed and documented as not 
clinically significant (NCS) if a subject is to be enrolled in the clinical study. After study drug 
administration, new abnormal findings or a worsening of an ongoing abnormal condition will be 
recorded as an AE.
8.5.2
Vital Sign Measurements 
Vital signs will be measured every 15 minutes during the infusion and as otherwise specified in the 
Schedules of Procedures for Part A (Table 1) and Part B (Table 2).

Body temperature will be an oral or tympanic measurement and methodology documented. 
Systolic blood pressure and diastolic blood pressure (SBP and DBP) and pulse (beats per minute) 
will be measured using a semiautomatic blood pressure recording device with an appropriate cuff 
size.  Blood pressure and pulse will be measured after the subject has rested for at least 5 minutes 
in the supine position. Respirations will be counted and documented in breaths per minute.  
Additional vital sign measurements may be performed as needed at the investigator’s discretion.  
8.5.3
Pulse Oximetry
Oxygen saturation will be continuously monitored via pulse oximetry with a fingertip monitor,
predose through 4 hours postdose.  Values should be recorded at the timepoints specified in the 
Schedules of Procedures for Part A (SCHEDULES OF ASSESSMENTS
Table 1) and Part B (Table 2).
Additional timepoints should also be recorded if necessary, at the discretion of the investigator, to 
follow up suspected adverse events.
8.5.4
Routine Electrocardiogram for Safety
Routine ECG measurements will be performed according to the Schedules of Procedures for Part 
A (SCHEDULES OF ASSESSMENTS
Table 1) and Part B (Table 2) after the subject has been in a supine position for at least 5 minutes. 
Routine ECG measurements will be performed in triplicate at Screening visit and on Day -1 
(predrug baseline).  Triplicate ECGs will be performed with a 1 minute interval and all 3 ECGs 
completed within 5 minutes.  At all other time points, routine ECG measurements will be 
performed as a single measurement.
The investigator will review, sign and date the ECG after recording to ensure the subject’s safety.  
The time of the ECG, as well as an overall conclusion, will be documented within the source.  The 
investigator will interpret the ECG using 1 of the following categories: normal, abnormal but not 
clinically significant (NCS), or abnormal and clinically significant (CS). If the overall conclusion 
is abnormal CS, the applicable AE must be recorded within the source. 
The ECG tracings should be collected and retained with the source documents for study 
monitoring.  
If possible the electronic data file with all generated ECG variables and electronic files with the 
digitized tracings will be transferred to the sponsor at the end of the clinical study.
8.5.5
Real-time Cardiac Monitoring (Electrocardiogram Telemetry)
Real-time cardiac monitoring will be performed as depicted in the Schedules of Procedures for 
Part A (SCHEDULES OF ASSESSMENTS
Table 1) and Part B (Table 2) as a tool to facilitate medical management of the subjects after 
dosing. The telemetry results will be reviewed by the investigator on a regular basis to identify

potential abnormalities. Start and end date and time of the telemetry will be documented within the 
source and any findings will be appropriately characterized (normal, abnormal NCS or abnormal 
CS). If telemetry findings are evaluated as abnormal CS, the appropriate AE should be 
documented within the source.
8.5.6
Laboratory Assessments
Samples for standard clinical laboratory tests will be obtained according to the Schedules of 
Procedures for Part A (SCHEDULES OF ASSESSMENTS
Table 1) and Part B (Table 2). Laboratory tests to be performed in this study are shown in Table 9.
Clinical Laboratory Tests.  
Blood samples will be collected via a peripherally placed IV cannula or by direct venipuncture in a 
suitable forearm vein.  Samples for clinical chemistry will be collected under fasting conditions 
and in accordance with acceptable laboratory procedures/protocols. 
A “clean catch” method will be used for urine collections.
Non-standard laboratory tests will be performed by appropriate bioanalytical laboratories 
specified by the sponsor.  Details for collection, processing, storage (if applicable), and shipment 
are provided in the Laboratory Manual.
8.5.6.1
Standard Clinical Laboratory Tests for Screening/Safety
Standard laboratory tests for screening/safety will be performed by each site’s local laboratory. 
Abnormal clinical laboratory values will be flagged as either high or low (or normal or abnormal) 
based on the reference ranges for each laboratory parameter. The investigator will determine 
whether any of the abnormally high or low results are clinically significant or not clinically 
significant. Clinical significance is defined as any variation in results that has medical relevance 
and may result in an alteration in medical care (e.g., active observation, diagnostic measures, or 
therapeutic measures). If a clinically significant change from the screening value is noted, the 
clinically significant value and reason for clinical significance will be documented as an AE (as 
described in Section 8.6.1). The investigator will continue to monitor the subject with additional 
assessments until the values have reached reference range or the values at Screening, or until the 
investigator determines that follow-up is no longer medically necessary.
Results should be reported immediately to the investigator and transferred electronically at the end 
of the study for incorporation into the trial database. Test data transfers should be performed to 
check accuracy and completeness.

Standard hematology, serum chemistry, coagulation, and urinalysis.


Whole Blood for PBMC Isolation
Samples will be obtained from all subjects predose. Additional post dose sample(s) will be 
collected prn if clinically indicated by the appearance of symptoms of anaphylaxis/anaphylactoid 
response/cytokine release syndrome or IRR.  Peripheral blood mononuclear cells (PBMCs) will be 
isolated from whole blood samples. PBMCs will be used to determine T cell proliferation and 
cytokine secretion in response to ex vivo gliadin stimulation (by an established proliferation 
assay). Surplus PBMCs, if any, might be used to perform the alternative assay.
Scheduled post-dose blood samples will be collected at approximately 144 hoursfor dose groups ≥ 
4 mg/kg in Part A and on Days 8 (predose) and 14 for the repeat dose group in Part B.
8.6
Adverse Events 
AEs will be collected from time of consent until final follow up. The investigator is responsible for 
reporting all AEs that are observed or reported during the study, regardless of their relationship to 
study drug or their clinical significance. If there is any doubt as to whether a clinical observation is 
an AE, the event should be reported.
An AE is defined as any untoward medical occurrence in a clinical investigation subject who has 
signed informed consent to participate in a study; it does not necessarily have to have a causal 
relationship with study participation or study treatment. AEs that occur after a subject provides 
informed consent but before the time of the first dose of study drug will be considered pretreatment 
AEs.  
8.6.1
Treatment Emergent Adverse Events
A treatment emergent adverse event (TEAE) is defined as any untoward medical occurrence in a 
clinical investigation subject administered study drug; it does not necessarily have a causal 
relationship with study drug. For simplicity, the protocol will refer to AEs.  The distinction of 
TEAE will be made in the data by a subject’s exposure to at least one dose of study drug.
An AE can therefore be any unfavorable and unintended sign (e.g., a clinically significant 
abnormal laboratory finding), symptom, or disease temporally associated with the use of a drug 
whether or not it is considered related to the study drug. 
The following should not be recorded as AE: 

Preplanned procedures unless the condition for which the procedure was planned has 
worsened after the subject signed informed consent; (however, complications resulting from 
an elective surgery should be reported as AEs).


Preexisting conditions found as a result of screening procedures.  These should be recorded as 
medical history; (however, worsening of an ongoing abnormal preexisting condition is to be 
recorded as an AE). 
Abnormal laboratory values or test results constitute AEs only if they induce clinical signs or 
symptoms, are considered clinically significant, require therapy or further diagnosis beyond repeat 
testing for confirmation alone. See also CTCAE Version 4.0 (Published: May 28, 2009 [v4.03: 
June 14, 2010]) or most current version.
Refer to Appendix 13.1, Liver Safety Monitoring and Assessment (Drug Induced Liver 
Injuiry, DILI) for detailed information on identifying, monitoring and assessing liver 
abnormalities if increases in liver function test values occur or a TEAE is suspected to be 
due to hepatic dysfunction.
8.6.2
Serious Adverse Events 
An SAE is defined as any untoward medical occurrence that at any dose:

Results in death

Is immediately life-threatening

The term “life threatening” refers to an event in which the subject 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

Requires inpatient hospitalization or prolongation of existing hospitalization

Results in persistent or significant disability/incapacity or substantial disruption of the ability 
to conduct normal life functions

Leads to a congenital anomaly/birth defect

Is an important medical event: 
Important medical events that may not result in death, be life threatening, or require 
hospitalization may be considered serious when, based upon appropriate medical judgment, 
they may jeopardize the subject and may require medical or surgical intervention to prevent 
one 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.

Any potential “Hy’s Law” or severe hepatic function abnormality as defined below, in the 
absence of another etiology, is to be considered an important medical event and must be 
promptly reported as an unexpected SAE associated with the use of the drug (i.e., reported 
even before all other possible causes of liver injury have been excluded). (See also Appendix 
13.1.)
o
ALT or AST > 3x upper limit of normal (ULN) and increase of total bilirubin > 2x ULN 
without evidence of intra- or extra-hepatic bilirubin obstruction (elevated ALP) or 
Gilbert’s syndrome (“Hy’s Law”) or

o
ALT or AST >8xULN or
o
ALT or AST >5xULN for more than 2 weeks or 
o
ALT or AST >3xULN with the appearance of fatigue, nausea, vomiting, right upper 
quadrant pain or tenderness, fever, rash, and/or eosinophilia (>5%) 
The initial report must occur before fully working up the patient to rule out other etiologies. 
Reporting should include all available information, especially that needed for evaluating the 
severity and likelihood that the drug caused the reaction, and should initiate a close follow-up until 
complete resolution of the problem and completion of all attempts to obtain supplementary data. 
An AE or suspected adverse reaction is considered “life-threatening” if, in the view of either the 
investigator or sponsor, its occurrence places the subject at immediate risk of death. It does not 
include an AE or suspected adverse reaction that, had it occurred in a more severe form, might 
have caused death.
8.6.3
AE Severity Assessment
The CTCAE Version 4.0 (Published: May 28, 2009 [v4.03: June 14, 2010]) or most current 
version will be used to assess and grade severity for AEs and laboratory abnormalities judged to be 
clinically significant.  Within each category, AEs are listed accompanied by their descriptions of 
severity (Grade 1-5).  Each AE term will be mapped to Medical Dictionary for Regulatory 
Activities (MedDRA) term and code.  For this study, the CTCAE will only be used for grading the 
severity for the AE and not for causality assessment. 
If an event is not covered by CTCAE Version 4.0, the guidelines shown in Table 10 should be used 
to assess severity.
Table 10. 
Severity Criteria Descriptions for AE not covered by CTCAE
Toxicity Grade / Severity
Description
Grade 1
Mild
The event is transient or mild discomfort; no limitation in activity; no medical 
intervention or therapy required. The subject may be aware of the sign or 
symptom, but tolerates it reasonably well. 
Grade 2
Moderate
The event causes mild to moderate limitation in activity, no or minimal medical 
intervention/therapy required. 
Grade 3
Severe
The event causes marked limitation in activity, medical intervention/therapy 
required. Hospitalization possible.  
Grade 4
Life-threatening
The subject is at risk of death due to the AE as it occurred.  This does not refer to 
an event that hypothetically might have caused death if it was more severe. 
Grade 5
Fatal
The subject dies due to the event. 
8.6.4
Causality of AEs
The relationship of each AE to study medication(s) will be assessed by the investigator or
delegated doctor of medicine (MD) subinvestigator using the following categories.  If a licensed

physician assistant who is delegated responsibility by the investigator provides initial assessment 
of causality, it must be confirmed in writing by the investigator or MD subinvestigator.
Causal relationship to the 
study drug
Criteria for causal relationship
Not related
A clinical event, including laboratory test abnormality, with a temporal relationship to 
study drug administration which makes a causal relationship improbable, and/or in 
which other drugs, chemicals or underlying disease provide plausible explanations.
Possible
A clinical event, including laboratory test abnormality, with a reasonable temporal 
sequence to administration of the study drug, but which could also be explained by 
concurrent disease or other drugs or chemicals. Information on drug withdrawal may be 
lacking or unclear.
Probable
A clinical event, including laboratory test abnormality, with a reasonable temporal 
sequence to administration of the study drug, unlikely to be attributed to concurrent 
disease or other drugs or chemicals, and which follows a clinically reasonable response 
on re-administration (re-challenge) or withdrawal (de-challenge).
8.6.5
Documenting AEs
AEs should be recorded as descriptively as possible (investigator terms) in the source.  Time of AE 
onset and resolution (if applicable) should be recorded for AEs occurring while the subjects are in 
the clinic.  Source should be sufficiently detailed to allow appropriate medical evaluation of AEs 
and the circumstance under which they occurred and to facilitate accurate and efficient coding and 
eCRF reporting and determine the necessity of medical follow up. 
At every study visit or telephone follow up, subjects will be asked a nondirected question to elicit 
any medically related changes in their well-being. They will also be asked if they have been 
hospitalized, had any accidents, used any new medications, or changed concomitant medication 
regimens (both prescription and non-prescribed/over-the-counter medications).
AEs must be followed to satisfactory resolution or until the investigator deems the event to be 
chronic or the condition to be stable. The description of the AE will include the onset date, 
duration, date of resolution, severity, seriousness, etiology, and the likelihood of relationship of 
the AE to study drug.
Collection of pretreatment AEs will commence from the time the subjects signs the informed 
consent to participate in the study and continue until the subject is first administered study drug. 
For subjects who discontinue study participation prior to study drug administration, pretreatment 
events are collected until the subject discontinues. Collection of TEAEs will begin from the time 
that the subject is first administered study drug through the last study procedure. 
Assessment of relationship to study drug will only be captured for TEAEs (AEs arising after the 
subject is first administered study drug). For AEs prior to dosing relationship to AEs will be 
deemed “not related”.

8.6.6
Collection and Reporting of Serious Adverse Events
The investigator may consult with the Cour medical monitor at any time regarding an AE; 
however, the Cour medical monitor is to be notified of any serious adverse event (SAE) and any 
Grade 2 or greater toxicity or DILI case within 24 hours of investigator’s (or designee’s) 
awareness of such an event.  
When a SAE occurs through the AE collection period it should be reported according to the 
following procedure.
A Cour SAE form must be completed and signed by the investigator immediately or within 
24 hours of first onset or notification of the event. The information should be completed as fully as 
possible but contain, at a minimum:

A short description of the event and the reason why the event is categorized as serious.

Subject identification number.

Investigator’s name.

Name of the study drug

Causality assessment.
The SAE form should be transmitted byfax within 24 hours of awareness to the attention of the 
contact listed below: 
Attn: Drug Safety Coordinator
US Fax: +1 888-301-7843
The AE eCRF and other relevant eCRFs (such as General Medical and Surgical History, 
Prior/Concomitant Medications, Vital Signs, and Concomitant Procedures) for the subject must be 
completed promptly and updated promptly with new information. If there are additional 
documents that support the SAE (e.g., clinic or hospital records, laboratory reports, or procedure 
reports), they should be obtained. Any SAE spontaneously reported to the investigator following 
the AE collection period should be reported to the sponsor if considered related to study drug.  
SAEs spontaneously reported >30 days after the last subject’s last procedure will not be captured 
in the trial database.
8.6.7
Collection and Reporting of Special Situations
Some events will be considered “special situations” and reported using the SAE form (special 
situation section) even though an associated SAE may not have been experienced by the study 
subject.  Examples are pregnancy (of a study subject or female partner of a male study subject; see 
also Section 8.6.9), overdose (see also Section 7.6), and medication error (i.e., an unintended 
failure in the drug treatment process that leads to, or has the potential to lead to harm to the 
patient).  Other “special situations” may be identified case-by-case.

8.6.8
Follow-up of SAEs
All SAEs should be followed up until resolution or until the investigator deems the event to be 
chronic or stable. The timelines and procedure for follow-up reports are the same as those for the 
initial report.
8.6.9
Pregnancy
Women with known or suspected pregnancy are excluded from the study. 
If a female subject or partner of a male subject becomes pregnant during the study dosing period or 
within 30 days from the last procedure or last dose, whatever is greater, the subject should inform 
the investigator immediately and subsequently the investigator should report the information to the 
sponsor on the SAE form (special situation section) as if it is an SAE.  The expected date of 
delivery or expected date of the end of the pregnancy, last menstruation, estimated conception 
date, pregnancy result and neonatal data etc., should be included in this information.  Should the 
partner of the male subject become pregnant, a separate informed consent form will be submitted 
for IRB review and approval that, upon signing by the pregnant female (subject’s partner), will 
allow medical supervision during the pregnancy and allow follow-up after the birth of the infant.
The investigator will follow the medical status of the mother, as well as the fetus, as if the 
pregnancy is an SAE and will report the outcome to the sponsor.
When the outcome of the pregnancy falls under the criteria for SAEs (spontaneous abortion, 
induced abortion, stillbirth, death of newborn, congenital anomaly [including congenital anomaly 
or developmental delay in the fetus or the child]), the investigator should respond in accordance 
with the report procedure for SAEs.  Additional information regarding the outcome of a pregnancy 
(which is categorized as an SAE) is mentioned below.

“Spontaneous abortion” includes miscarriage, abortion and missed abortion.

Death of an infant within 1 month after birth should be reported as an SAE regardless of its 
relationship with the study drug.

If an infant dies more than 1 month after the birth, the death should be reported if a relationship 
between the death and intrauterine exposure to the study drug is judged as “possible” by the 
investigator.

In the case of a delivery of a living newborn, the “normality” of the infant is evaluated at the 
birth (e.g., the Apgar score).

Unless a congenital anomaly is identified prior to spontaneous abortion or miscarriage, the 
embryo or fetus should be assessed for congenital defects by visual examination.

TIMP-GLIA Concentration and Pharmacokinetics
8.7.1
Blood Collection for PK
Serial blood samples will be collected in a K2 EDTA tube for measurement of TIMP-GLIA in 
plasma at the times relative to infusion start time as shown in the Schedules of Procedures for 
Part A (SCHEDULES OF ASSESSMENTS
Table 1) and Part B (Table 2). The scheduled times relative to infusion start should be 
implemented as indicated; however, some time windows of PK blood collection will be allowed, if 
necessary, as shown in Appendix 13.3. 
Samples for PK are to be drawn from the opposite arm from which study drug is being infused.  
Sample processing, storage, and shipment instructions are described in the Laboratory Manual. 
TIMP-GLIA concentration measurement will be performed by a validated ELISA assay (LLOQ = 
0.05 μg/mL) by a bioanalytical laboratory specified by the sponsor. The method detects gliadin 
that has been released from the TIMP-GLIA matrix and is present in plasma.
8.7.2
Estimation of PK Parameters
Individual subject plasma TIMP-GLIA concentrations over time (actual time elapsed from dosing) 
will be used to derive PK parameters using non-compartmental analysis (NCA). The primary PK 
parameters are maximal observed concentration (Cmax), last measurable concentration (Clast), time 
of maximal observed concentration (Tmax), time of last measurable concentration (Tlast), and area 
under the curve from time zero and extrapolated to infinity (AUCinf) and area under the 
concentration-time curve from time zero to time of the last measurable concentration (AUClast).  
Other PK variables will be derived if feasible: terminal elimination half-life (t½), area under the 
curve over the dosing interval (AUCτ), area under the curve from time zero (time of dosing) to time 
t, where a relevant t will be determined based upon the observed data (AUCt), total body clearance 
(CL), volume of distribution (Vd), and accumulation index (Racc).  The terminal half-life will be 
calculated as t½ = ln(2)/λz, where λz is the terminal rate constant. λz will be estimated as the slope 
from a linear regression with the natural logarithm to the concentration as the response variable, 
and time as the explanatory variable. Valid observations from the final part of the curve, which is 
approximately linear, will be used for the analysis. Pharmacokinetic analysis results may be 
provided in a separate PK report.
8.8
Total Amount of Blood
The approximate total blood volume taken per CD subject in Part A is 307mL and in Part B is
462 mL over 3 months (screening through Day 60).  Volumes may increase should the subject 
require unscheduled testing to follow up suspected adverse events.  
8.9
Priority of Actions
The following order of procedures will be in effect when more than 1 assessment is required at a 
time point with blood sampling for pharmacokinetics/metabolic profiling being collected nearest 
to the scheduled time point:

STATISTICAL METHODS
A statistical analysis plan (SAP) will be prepared and finalized prior to database lock, at the latest. 
This document will provide further details regarding the definition of analysis variables and 
analysis methodology to address all study objectives along with specifications for tables, listings 
and figures (TLFs) to be produced. Any changes from the analyses planned in the SAP will be 
justified in the clinical study report.
Prior to database lock a review of the clinical study data will be performed and final data queries 
identified, if necessary.
9.1
Sample Size
No sample size calculation was performed. The sample size is based upon precedent set by other 
clinical studies of similar nature and is considered sufficient to achieve the study objectives. 
9.2
Analysis Sets
9.2.1
Safety Set
The safety analysis set (SAF) will include all enrolled subjects who received at least 1 dose of 
study drug. 
The SAF will be used for summaries of demographics and baseline characteristics and all safety 
and tolerability variables.
9.2.2
Pharmacokinetic Analysis Set
The PK analysis set (PKAS) is a subset of the SAF for which concentration data are available to 
facilitate derivation of at least 1 primary PK parameter and for whom the time of dosing on the day 
of sampling is known. Inclusion of subjects in the PKAS with missing data or protocol deviations
will be considered by the pharmacokineticist on a case-by-case basis.
The PKAS will be used for all tables and graphical summaries of PK data. 
9.3
Demographics and Other Baseline Characteristics
Demographics and other baseline characteristics including sex, age, race, ethnicity, height, weight, 
and the HLA type (HLA-DQ2.5 or HLA-DQ8.1) will be summarized for the SAF and PKAS.   
Medical history data will be summarized for the SAF using the number of observations and 
percentage of subjects reporting each category.  
9.4
Subject Disposition
The number of subjects who enter and complete each phase of the study will be tabulated.  
Numbers of subjects who fail to complete the study will be tabulated and categorized by reason for 
termination.

Safety Analysis
No formal statistical analyses will be conducted. All safety and tolerability data for the SAF will 
be listed. In general, all data will be summarized with descriptive statistics (number of subjects, 
mean, standard deviation [SD], coefficient of variation [CV], minimum, median, and maximum 
and geometric mean where applicable) for continuous endpoints, and frequency and percentage for 
categorical endpoints.  Percentages by categories will be based on the number of subjects with no 
missing data, i.e., will add up to 100%.  Changes from predose baseline may also be presented for 
laboratory values, pulse oximetry, and vital signs as appropriate. Physical examination findings 
and ECG abnormalities will be listed.  
Data will be presented overall and by dose level for each phase of study (Part A, Part B).
Presentation by dose (mg) administered may also be included, as appropriate.
9.5.1
Adverse Events
AEs will be coded using MedDRA. All AEs will be listed.
AE summary tabulations will specify number and percentage of subjects who experienced an AE
presented by MedDRA System Organ Class and MedDRA Preferred Term, and CTCAE grading 
(severity) overall and by dose level for each study phase (Part A, Part B). Separate summaries will 
be presented for TEAEs, serious TEAEs, TEAEs leading to discontinuation, and TEAEs related to 
study drug. The number of events will also be presented by MedDRA System Organ Class and 
MedDRA Preferred Term, and CTCAE grading (severity) overall and by dose level for each study 
phase (Part A, Part B). AE tabulation and listing descriptions will be provided in the SAP. 
At each level of incidence reporting, a subject will be counted once if the subject reports 1 or more 
events at that level.
In the case of duplicate preferred terms for a subject:

the most severe case will be reported 

drug relatedness status, most conservative assessment, will be reported 
Additional AE data capture and reporting conventions include but are not limited to:

If the onset time of an AE starting on Day 1 is not known relative to dosing start time on Day 1, 
the AE will be considered treatment-emergent.

If only a partial AE onset date is available (month/year) and it is the same as the month/year of
Day 1 and the full AE end date (day/month/year) is on or after Day 1, the AE will be 
considered treatment-emergent. 

If only a partial AE onset date is available (month/year) and the full AE end date is before 
Day 1, the AE will not be considered treatment-emergent.

If only a partial AE onset date (month/year) and only a partial AE end date (month/year) are 
available and both are the same month/year of Day 1, the AE will be considered

9.5.2
Vital Sign Measurements and Pulse Oximetry
Vital sign measurements (systolic and diastolic blood pressure [mmHg], heart rate [beats/minute], 
respiration rate [breaths/minute], and body temperature [°C]) and oxygen saturation (SO2, %) 
measurements will be displayed in the listings and will be summarized in tabulations. In addition 
to summary statistics, inner quartile percentiles will be reported. Change from baseline by 
visit/timepoint will also be reported using the number of subjects with the reported value, mean, 
median, SD, minimum value, maximum value, and inner quartile percentiles. Subjects with 
missing data for a given visit will not contribute to the tabulations for that visit.
9.5.3
Clinical Laboratory Test Results
Laboratory test results will be listed with each out of range value classified as low (L) or high (H) 
according to the laboratory-supplied reference ranges or defined reference range for the study. 
Results will be summarized in tabulations by treatment group and visit/timepoint using descriptive 
statistics where applicable for quantitative laboratory measurements. 
Tables showing shift from baseline will also be presented.
The presence of antibodies, where detected, will be summarized descriptively and/or graphically 
presented.  Further details will be provided in the SAP. 
9.5.4
Physical Examination and Safety ECG Findings
All physical examination results will be listed.
Changes from Screening in PE and ECG results will be listed by subject for all subjects in the SAF. 
Height and weight will be summarized by summary statistics. The number of baseline abnormal 
findings and the percentage of subjects with abnormalities will be reported. A table will be 
provided, to report findings that represent changes from the baseline condition at each visit (for PE 
this table will be subdivided by each of the body systems).
9.5.5
Previous and Concomitant Medication 
Previous and concomitant medications will be coded with the World Health Organization’s Drug 
Dictionary (WHO-Drug).  Previous medication (medication history) is defined as drugs and 
therapies taken before first dosing.  Concomitant medication is defined as drugs and therapies used 
after first dosing, including those that started before dosing and continued after dosing.
All previous and concomitant medications will be listed by subject.
9.5.6
Statistical Analysis of Pharmacokinetics
Individual subject concentrations of TIMP-GLIA will be listed by subject and summarized by 
study phase (Part A, Part B), dose level, and scheduled sample time (nominal time) and study day.

well as derived pharmacokinetic parameters.
Graphics for TIMP-GLIA concentrations, including mean concentration-time profiles, individual 
subject concentration-time profiles (both linear and logarithmic-linear) and overlay (“spaghetti”) 
plots of concentrations-time profiles will be produced as appropriate overall and by study phase 
(Part A, Part B) and dose level. Presentation taking into account dose (mg) administered may also 
be included, as appropriate.
9.6
Missing or Outlier Data
Missing values for safety data (except for dates) will not be imputed. Missing or partial dates will 
be imputed as described in the SAP.
As a general principle, no imputation of missing data will be done.  Incomplete data for AEs (e.g., 
partial dates) and inaccurate data for laboratory parameters (e.g., values below the lower limit of 
quantification, LLOQ) will be considered for imputation.
TIMP-GLIA concentration values below the LLOQ will be set to zero for calculation of summary 
statistics.  If one or more values are less than the LLOQ, the geometric mean will not be calculated. 
The handling of missing concentration data points, below the LLOQ data points, outlier data 
points, and individual outlier PK parameter values will be described in the SAP.
Further details will be provided in the SAP.
9.7
Interim Analysis 
Interim data locks for data collected through the end of the investigational period (Day 60) may be 
performed and after each part of study so that the key data can be reviewed and reported. Datasets 
affected by data availability during the follow-up period will be augmented. Details will be 
provided in the SAP.

minimum demographic data (sex, birth date, race and informed consent date), outcome of 
eligibility assessment (inclusion and exclusion criteria), reason for screening failure and AEs 
details must be document within the source.
The investigator or designee will be responsible for case report form completion and that all data 
and queries are accurate, complete and are verifiable with the source.  The source should be 
appropriately maintained by the clinical unit.
Electronic case report forms (eCRFs) and any supporting documents should be available for 
review/retrieval by the sponsor/designee at any given time.
10.1.2
Specification of Source Documents
Source data may be paper and/or electronic and must be available at the clinical unit to document 
the existence of the study subjects and to substantiate protocol adherence and integrity of study 
data.  Source data must include the original documents relating to the study, as well as the medical 
treatment and medical history of the subject. 
The following information should be included within the source records:
1. Demographic data (date of birth [DD MMM YYYY], sex, race, ethnicity, height and body 
weight, BMI),
2. Inclusion and exclusion criteria details,
3. Participation in clinical study and signed and dated informed consent forms, 
4. Visit dates,
5. Medical and medication history and physical examination details,
6. Key pharmacokinetic and safety data (including dates and times of scheduled and unscheduled 
procedures, events, tests),

Clinical Study Monitoring
The sponsor or delegated contract research organization (CRO) is responsible for monitoring the 
clinical study to ensure that subject's human rights, safety and well-being are protected, that the 
study is properly conducted in adherence to the current protocol and GCP, and study data reported 
by the investigator/subinvestigator are accurate and complete and that they are verifiable with 
study-related records such as source documents.  The sponsor is responsible for assigning study 
monitor(s) to this study for proper monitoring.  They will monitor the study in accordance with 
planned monitoring procedures. This includes verifying that the FDA Form 1572 and site 
signature log and PI’s delegation of responsibility log and other regulatory documents are current, 
and that any protocol deviations are documented with appropriate notifications made (e.g., 
sponsor, IRB, regulatory authorities) in a timely manner. Monitoring will include a combination of 
procedural verification (e.g., study drug preparation, timing of procedures) as well as source data 
verification (e.g., reconciliation of source data to (e)CRFs, verification of study records for GCP 
compliance) as appropriate.
It is important that the investigator and other study personnel are available during the monitoring 
visits to support clinical study monitoring.
10.1.4
Direct Access to Source Data/Documents/Inspection of Records
The investigator must permit monitoring and auditing by the sponsor or delegated CRO as well as 
inspections from the IRB/independent ethics committee (IEC) and relevant regulatory authorities.  
In these instances, they must provide all study-related records, such as source documents, when 
they are requested by the sponsor monitors and auditors, the IRB/IEC, or regulatory authorities.  
The confidentiality of the subject's identities shall be well protected consistent with local and 
national regulations when the source documents are subject to direct access.  The sponsor or 
designee monitor will not collect individually identifying information (e.g., name, address, social 
security number) on trial participants.
The auditor or inspector may ask to visit the facilities where procedures are performed, records are
collected, where the study drug is stored and prepared, and any other facility used during the study. 
In the event of an audit, investigator agrees to allow the sponsor, representatives of the sponsor, the 
FDA, or other regulatory agency access to inspect relevant facilities. 
If the study site is contacted for an inspection by a regulatory body, the sponsor should be notified 
immediately.

Data Management
Data Management will be coordinated by the designee of the sponsor and the designee’s 
procedures and documentation policies will be followed. All study-specific processes and 
definitions will be documented by Data Management.  Coding of medical terms and medications 
will be performed using MedDRA and WHO-Drug respectively.
10.1.6
Protocol Deviations
A protocol deviation is an unplanned excursion from the protocol that is not implemented or 
intended as a systematic change.  A significant deviation occurs when there is nonadherence to the 
protocol that results in a significant, additional risk to the subject when the subject or investigator 
has failed to adhere to significant protocol requirements. Significant deviations can include 
nonadherence to inclusion or exclusion criteria, enrollment of the subject without prior sponsor 
approval, or when there is nonadherence to FDA or other applicable regulations and/or ICH 
E6(R2) guidelines. 
The investigator is responsible for ensuring the study is conducted in accordance with the 
procedures and evaluations described in this protocol and must protect the rights, safety and 
welfare of subjects.  The investigator should not implement any deviation from, or changes of, the 
protocol, unless it is necessary to eliminate an immediate hazard to study subjects.
A protocol waiver is a documented prospective approval of a request from an investigator to 
deviate from the protocol.  Protocol waivers are strictly prohibited.
For the purposes of this protocol, deviations requiring notification to sponsor are defined as any 
unplanned incidents involving noncompliance with the final approved protocol, including but not 
limited to, any subject who:

Protocol deviation 1 – Entered the study even though they did not satisfy entry criteria 

Protocol deviation 2 – Developed withdrawal criteria during the study and was not withdrawn

Protocol deviation 3 – Received wrong treatment or incorrect dose 

Protocol deviation 4 – Received excluded concomitant treatment
When a deviation from the protocol is identified for an individual subject, the investigator or 
designee must ensure the sponsor is notified.  The sponsor or designee will follow-up with the 
investigator, as applicable, to assess the deviation and the possible impact on the safety and/or 
pharmacokinetic parameters of the subject to determine subject continuation in the study. 
If a deviation impacts the safety of a subject, the investigator must contact the sponsor or 
designated Clinical Contact immediately.
The investigator will also assure that deviations meeting IRB’s and applicable regulatory 
authorities’ criteria are documented and communicated appropriately to the IRB and applicable 
regulatory authorities.  All documentation and communications to the IRB and applicable 
regulatory authorities will be provided to the sponsor or designee and maintained within the trial 
master file.

NOTE:  Other deviations outside of the categories defined above that are required to be reported to 
the IRB in accordance with local requirements will be reported, as applicable.
10.1.7
Modification of the Protocol
Any changes in this research activity, except those necessary to remove an apparent, immediate 
hazard to the subject, must be reviewed and approved by the sponsor or its designee. Amendments 
to the protocol must be submitted in writing to the investigator’s IRB and, if applicable, to the 
appropriate regulatory authorities for approval before subjects can be enrolled into an amended 
protocol.
10.1.8
End of Trial in All Participating Countries
The end of the clinical study is defined as the last subject’s last study visit (late follow-up visit).
10.2
Ethics and Protection of Subject Confidentiality
10.2.1
Institutional Review Board/Ethics Committee/Regulatory Authorities
Good Clinical Practice (GCP) requires that the clinical protocol, any protocol amendments, the 
investigator’s brochure, the informed consent form(s) and all other forms of subject information 
related to the study (e.g., advertisements used to recruit subjects) and any other necessary 
documents be reviewed by an IRB/IEC. The IRB/IEC will review the ethical, scientific and 
medical appropriateness of the study before it is conducted. IRB/IEC approval of the protocol, 
informed consent form(s) and subject information and/or advertising, as relevant, will be obtained 
prior to the authorization of drug shipment to a study site.
Any substantial amendments to the protocol will require IRB/IEC approval prior to 
implementation of the changes.  The investigator will be required to submit, maintain and archive 
study essential documents according to ICH GCP.
Any SAEs that meet reporting criteria, as dictated by local regulations, will be reported to both 
responsible ethics committees and regulatory agencies, as required. During the conduct of the 
study, the investigator should promptly provide written reports (e.g., ICH Expedited Reports, and 
any additional reports required by local regulations) to the IRB/IEC of any changes that affect the 
conduct of the study and/or increase the risk to subjects. Written documentation of the submission 
to the IRB/IEC should also be provided to the sponsor.
If required by local regulations, the investigator shall make accurate and adequate written progress 
reports to the IRB/IEC at appropriate intervals, not exceeding 1 year. The investigator shall make 
an accurate and adequate final report to the IRB/IEC within the applicable requirements.
10.2.2
Ethical Conduct of the Study
The study will be conducted in accordance with the protocol, ICH guidelines, applicable 
regulations and guidelines governing clinical study conduct and the ethical principles that have

Informed Consent of Subjects
The requirements of the informed consent are described in Appendix 13.2. 
The investigator or his/her representative will explain the nature of the study to the subject or 
his/her guardian or legal representative, and answer all questions regarding this study.  Prior to any 
study-related screening procedures being performed on the subject, the informed consent 
statement will be reviewed and signed and dated by the subject or his/her guardian or legal 
representative, the person who administered the informed consent and any other signatories 
according to local requirements. A copy of the signed informed consent form will be given to the 
subject and the original will be placed in the subject’s medical record. An entry must also be made 
in the subject’s dated source documents to confirm that informed consent was obtained prior to any 
study-related procedures and that the subject received a signed copy.
The signed informed consent forms will be retained by the investigator and made available (for 
review only) to the study monitor and auditor, regulatory authorities and other applicable 
individuals upon request.
10.2.4
Subject Confidentiality
Individual subject medical information obtained because of this study is considered confidential.
The sponsor affirms the subject's right to protection against invasion of privacy. Only a subject 
identification number and/or initials, sex, and date of birth (or year of birth as per local 
requirement) will identify subject data retrieved by the sponsor. However, the sponsor requires the 
investigator to permit the sponsor, sponsor's representative(s), the IRB/IEC and when necessary, 
representatives of the regulatory authorities to review and/or to copy any medical records relevant 
to the study.
The sponsor will ensure that the use and disclosure of protected health information obtained during 
a US research study is consistent with federal and/or regional legislation related to the privacy and 
protection of personal information (i.e., Health Insurance Portability and Accountability Act).
10.3
Insurance and Compensation for Injury
Each subject in the study must be insured in accordance with the regulations applicable to the site 
where the subject is participating. If a local underwriter is required, then the sponsor or sponsor’s 
designee will obtain clinical study insurance against the risk of injury to clinical study subjects. 
Refer to the Clinical Study Site Agreement regarding the sponsor’s policy on subject 
compensation and treatment for injury. If the investigator has questions regarding this policy, he or

13 APPENDICES
13.1
Liver Safety Monitoring and Assessment (Drug Induced Liver Injuiry, DILI)
Any subject enrolled in a clinical study with active drug therapy that reveals an increase of serum 
aminotransferases > 3 x ULN or bilirubin > 2 x ULN should undergo detailed testing for liver 
enzymes (including at least ALT, AST, ALP and TBL).  Testing should be repeated within 48 to 
72 hours of notification of the test results.  For studies for which a central laboratory is used, alerts 
will be generated by the central laboratory regarding moderate and severe liver abnormalities to 
inform the investigator, study monitor and study team.  Subjects should be asked if they have any 
symptoms suggestive of hepatobiliary dysfunction.
Definition of Liver Abnormalities
Confirmed abnormalities will be characterized as moderate and severe where ULN:
ALT or AST
TBL
Moderate
> 3 x ULN 
or
> 2 x ULN
Severe†
> 3 x ULN
and
> 2 x ULN
† Hy’s Law Definition: Drug-induced jaundice caused by hepatocellular injury, without a significant obstructive component, has a 
high rate of bad outcomes, from 10% to 50% mortality (or transplant).  The 2 “requirements” for Hy’s Law are: 1) Evidence that a 
drug can cause hepatocellular-type injury, generally shown by an increase in transaminase elevations higher than 3 x ULN (“2 x 
ULN elevations are too common in treated and untreated patients to be discriminating”).  2) Cases of increased bilirubin (at least 2 
x ULN) with concurrent transaminase elevations at least 3 x ULN and no evidence of intra- or extra-hepatic bilirubin obstruction 
(elevated ALP) or Gilbert’s syndrome [Temple, 2006].
In addition, the subject should be considered to have severe hepatic abnormalities for any of the 
following:

ALT or AST > 8 x ULN.

ALT or AST > 5 x ULN for more than 2 weeks.

ALT or AST > 3 x ULN and International Normalized Ratio (INR) > 1.5 (if INR testing is 
applicable/evaluated).

ALT or AST > 3 x ULN with the appearance of fatigue, nausea, vomiting, right upper quadrant 
pain or tenderness, fever, rash and/or eosinophilia (> 5%).
The investigator may determine that abnormal liver test (LT) results, other than as described 
above, may qualify as moderate or severe abnormalities and require additional monitoring and 
follow-up.
Follow-up Procedures
Confirmed moderate and severe abnormalities in hepatic functions should be thoroughly 
characterized by obtaining appropriate expert consultations, detailed pertinent history, physical 
examination and laboratory tests.  The investigator or designee should complete a liver 
abnormality case report form (LA-CRF) or collective of appropriate CRFs capturing required

information, and/or another appropriate document (e.g., liver abnormality source document(s)).  
Subjects with confirmed abnormal LT results should be followed up as described below.
Confirmed moderately abnormal LTs should be repeated 2 to 3 times weekly then weekly or less if 
abnormalities stabilize or the study drug has been discontinued and the subject is asymptomatic.
Severe hepatic function abnormalities as defined above, in the absence of another etiology, may be 
considered an important medical event and may be reported as an SAE.  The sponsor should be 
contacted and informed of all subjects for whom severe hepatic liver function abnormalities 
possibly attributable to study drug are observed.
To further assess abnormal hepatic laboratory findings, the investigator is expected to:

Obtain a more detailed history of symptoms and prior or concurrent diseases. Symptoms and 
new-onset diseases should be recorded as “AEs” on the AE page within the source.  Illnesses 
and conditions such as hypotensive events and decompensated cardiac disease that may lead to 
secondary liver abnormalities should be noted. Nonalcoholic steatohepatitis is seen in obese 
hyperlipoproteinemic and/or diabetic patients, and may be associated with fluctuating 
aminotransferase (AT) levels.  The investigator should ensure that the medical history 
documentation captures any illness that predates clinical study enrollment that may be relevant 
in assessing hepatic function. 

Obtain a history of concomitant drug use (including nonprescription medication, 
complementary and alternative medications), alcohol use, recreational drug use and special 
diets.  Medications, including dose, should be entered on the concomitant medication page 
within the source.  Information on alcohol, other substance use and diet should be entered on 
the LA-CRF or collective of appropriate CRFs and/or other appropriate documents (e.g., liver 
abnormality page(s) from the source).

Obtain a history of exposure to environmental chemical agents.

Based on the subject’s history, other testing may be appropriate including: 
o
Acute viral hepatitis (A, B, C, D, E or other infectious agents), 
o
Ultrasound or other imaging to assess biliary tract disease,
o
Other clinical laboratory tests including INR, direct bilirubin.

Consider gastroenterology or hepatology consultations.

Submit results for any additional testing and possible etiology on the LA-CRF or collective of 
appropriate CRFs and/or other appropriate documents (e.g., liver abnormality page(s) from the 
source).
Study Subject Discontinuation
In the absence of an explanation for increased LTs, such as viral hepatitis, preexisting or acute 
liver disease or exposure to other agents associated with liver injury, the subject may be 
discontinued from the study.  The investigator may determine that it is not in the subject’s best 
interest to continue study enrollment.  Alternatively, the investigator may determine that it is in the 
subject’s best interest to continue study enrollment to undergo planned and additional medical

supervision and testing to adequately follow up the subject’s condition. Discontinuation of 
treatment should be considered if:

ALT or AST > 8 x ULN.

ALT or AST > 5 x ULN for more than 2 weeks.

ALT or AST > 3 x ULN and TBL > 2 x ULN or INR > 1.5 (if INR testing is 
applicable/evaluated).

ALT or AST > 3 x ULN with the appearance of fatigue, nausea, vomiting, right upper quadrant 
pain or tenderness, fever, rash and/or eosinophilia (> 5%).
In addition, if close monitoring of a subject with moderate or severe hepatic laboratory tests is not 
possible, study drug should be discontinued.

Amendment 1: Summary of Changes To Protocol Version 1.0
The final protocol TGLIA-5.001 version 1.0 dated 18 Jul 2017 has been revised to version 2.0 
dated 28 Aug 2017 to include substantantial and nonsubstantial (administrative) changes as 
detailed in the table below. 
SUBSTANTIAL CHANGES
Description of Change
Affected Section(s) in Amended Protocol Version 
2.0
Design – Enrollment for Dose Escalation Cohorts
Accelerated titration design for the first 2 dose levels 
of Part A was changed from 1+1 to 2+2. Cohorts of 2 
subjects will be enrolled at dose level 1 and dose level 
2. If dose-limiting toxicity (DLT) occurs in 1 of the 
subjects, the Safety Committee may expand
enrollment at the same dose level by 2 subjects.

(Within A Cohort)
Design – Cohort Expansion
Beyond the 2+2 and 3+3 cohort expansions in the 
event of a DLT, a provision was added to allow the 
Safety Committee to expand a dose cohort up to a 
total of 12 subjects to better define the relationship 
between dose and emerging safety signals.

(Within A Cohort)
Description of maximum tolerable dose (MTD)
Was: If no more than 1 subject experiences a DLT in 
each of the planned dose cohorts, the highest tested 
dose will be the MTD.  
In the context of the cohort expansions, the 
description has been revised such that the highest 
dose level that did not cause unacceptable side effects 
will be considered the MTD.
Section 7.3.3 Dose Escalation – Dosing Subjects At 
the Next Dose Level
Planned Number of Subjects
Because each of the first 2 dose levels will enroll at 
least 2 subjects, the planned enrollment for Part A 
increased from 17 to 19 subjects and the overall 
planned enrollment for the study increased from 20 to 
22 subjects.

such time the toxicity will be investigated by the 
Safety Committee to determine whether the study can 
resume or if the Study Stopping Criteria were met.
Visits
In Part A, the Day 14 (+/- 2 days) visit was changed 
from a telephone contact visit to an outpatient visit so 
that safety tests and assessments could be performed. 
Another outpatient visit at Day 60 (+/-3 days) was 
added. Telephone contact visits (regarding the 
subject’s diet, well-being, occurrence of adverse 
events, and concomitant medication use) by a health
care practitioner were added at Day 90, Day 120 and 
Day 180 (all +/- 3 days).
In Part B an outpatient visit at Day 60 (+/-3 days) was 
added so that safety tests and assessments could be 
performed. Telephone contact visits (regarding the 
subject’s diet, well-being, occurrence of adverse 
events, and concomitant medication use) by a

A minimum body weight of 33 kg was added to the 
requirement of BMI of >16 kg/m2.  The maximum 
BMI of 32 kg/m2 was replaced with a maximum body 
weight of 129 kg.  The requirement that subjects who 
are underweight or overweight or obese must be 
otherwise healthy in the opinion of the investigator 
remains unchanged. This adjustment prevents 
unnecessary exclusion of otherwise healthy patients 
of smaller or larger stature in the celiac disease 
community. In addition, the minimum and maximum 
weights provide consistency with the pharmacy 
manual dose calculations for subjects whose stature 
may be at the extremes. 
Synopsis Inclusion Criterion #4
Section 4.1 Inclusion Criterion #4
The duration of no known gluten exposure was 
reduced from “approximately 2 months prior to 
enrollment” to “at least 10 days prior to the Screening 
Visit.” The antigen-specific IgG response to gluten 
would generally peak at ~2 weeks and would last for 
~4-5weeks. Therefore, a bonafide immune response 
to the gluten intake would be identified by the 
screening celiac serology testing. In addition, a 
predose DGP-specific IgG will be recorded to capture 
the change from the screening value and to set the
predose baseline. 
Synopsis Inclusion Criterion #5c
Section 4.1 Inclusion Criterion #5c
Section 8.3 Diet History
The criterion was revised such that either a weak 
positive or negative celiac serology value is 
acceptable (either tTG-specific IgA or, for 
IgA-deficient subjects, DGP-specific IgG).  The 
study does not include a gluten challenge that would 
necessitate an optimization of the pre-challenge 
conditions.  Relaxing the criterion is not expected to 
alter safety or tolerability and should facilitate 
recruitment.

Description of Change
Affected Section(s) in Amended Protocol Version 
6.0
Clarification was added that cases of overdose should be 
reported to the sponsor as a “special situation” and any 
SAEs arising from overdose should be reported according 
to the specified procedures.
Protocol section 7.5 Emergency Procedures and 
Management of Overdose
Within the table of Clinical Laboratory Tests, the 
descriptive subtitle “Additional thrombotic/vascular 
markers” was added for the tests D-dimer, vWG, ICAM-1, 
fibrinogen, prothrombin fragment 1, 2, P-selectin.
Table 9 (was Table 11) Clinical Laboratory Tests
Cross reference to NCI CTCAE Version 4.0 (Published 
May 28, 2009 [v4.03: June 14, 2010]) or most current 
version was added in context of assessment of laboratory 
abnormalities as adverse events.
Section 8.6.1 Treatment Emergent Adverse Events
For emphasis, the description of Hy’s Law or severe 
hepatic function abnormality in the absence of 
another etiology was duplicated from Appendix 13.1 
Liver Safety Monitoring and Assessment (Drug 
Induced Liver Injury, DILI) in the protocol section 
defining SAEs and important medical events.
Protocol section 8.6.2 Serious Adverse Events
DILI case was called out to be reported to the medical 
monitor within 24 hours.
Protocol section 8.6.6 Collection and Reporting of Serious 
Adverse Events
Overdose, medication error, and pregnancy were defined 
as special situations to report to the sponsor.  Note: 
Subsequent level 3 subsections were renumbered owing to 
this addition.
Protocol section 8.6.7 Collection and Reporting of Special 
Situations
Pregnancy outcome “congenital anomaly” description was 
revised for clarification. Reference is made to the SAE 
“form” rather than “worksheet” for consistency with 
section 8.6.6 Collection and Reporting of Serious Adverse 
Events.
Protocol section 8.6.9 (formerly 8.6.8) Pregnancy
For clarification, rationale for 30 minute and 35 minute 
post dose collection is provides and instruction to 
postpone the 35 minute collection to actual end of infusion 
if an infusion interruption >5 minutes occurs.
Protocol section 8.7.1 Blood Collection for PK
Clarification was made within Follow-up Procedures that 
liver abnormality information may  be collected via a 
collective of appropriate CRFs not just one liver 
abnormality CRF (LA-CRF).
Clarification was added that the last section refers to 
subject, not study, discontinuation.
A statement was added that it could be in the subject’s best 
interest to continue enrollment in the study to facilitate the 
additional testing and close medical observation to follow 
up a potential DILI. This is particularly relevant in a study 
with a single dose arm.  Discontinuation of treatment 
would be considered separately from discontinuation from 
study.

Cytokines via multiplex assay on Days 7 and 14 (Part A) and Days 14 and 21 (Part B)
o
Gliadin-specific T cell proliferation and cytokine secretion on Day 7 (Part A) Days 8 
and 14 (Part B)

Clarification to the cytokines reported as part of the multiplex assay

Corrections to minor typographical errors
Effect on Consent Form: 
For Part B of the study, the telephone visit at Day 21 has been changed to a clinic visit.
In most cases the site informed consent(s) for Parts A and B will NOT require a change because the 
language used to describe the tests above is not specific, nor does the volume of blood drawn over 
the course of the study change significantly.  All sites are instructed to review their consent to 
ensure a change is not required.

The overall purpose of the amendment includes the following:

Instructions to manage mild to moderate infusion related reactions (IRR)

Change to highest dose from 10 mg/kg to 10 mg/kg or a maximum of 750 mg
Effect on Consent Form:

13.12 Amendment 8: Summary of Changes to Protocol Version 9.0
The overall purpose of the amendment includes the following:

Specifying dose to be administered to subjects enrolled into Part B: 8 mg/kg up to a maximum 
of 650 mg

Instructions for escalating rate of dose administration for subjects enrolled into Part B to 
minimize risk of infusion reaction

Add collection of C3a and SC5B-9 complement levels at 15 and 30 minutes during infusion 
and at 24 hours following infusion for subjects enrolled in Part B to monitor for (sub-)clinical 
complement activation

Clarify timing of pharmacokinetic sampling times
Effect on RISKS Section of the Consent Form for Part B: 
The “Risk” Section of the Informed Consent for Part B should be updated as follows:
“TIMP-GLIA has been given as a single infusion to 17 subjects with celiac disease (Part A of this 
study).  At the highest dose tested, approximately 650 mg, 2 of 4 subjects experienced a moderate 
infusion reaction.  For one of the subjects the infusion was stopped and the signs and symptoms 
went away immediately.  For the second subject, the infusion was stopped and the signs and 
symptoms went away immediately, and the infusion was restarted at a slower rate.  The subject 
completed the infusion without any other problems.
Signs and symptoms of an infusion reaction to TIMP-GLIA include flushing (warm feeling or
reddening of face, back and/or chest), rash, nausea, vomiting, back pain, low or high blood 
pressure, or increase in heart rate.  These symptoms were mostly mild to moderate.  All symptoms 
started within 2 minutes of the infusion starting and went away very quickly when the infusion was 
stopped or interrupted.
During studies in animals, some animals developed abnormalities in laboratory tests or in their 
tissues when TIMP-GLIA was given at doses higher than what is planned for this research study. 
Based on these animal studies it is is possible that TIMP-GLIA could cause an increase in the time 
it takes for your blood to coagulate, which may cause bleeding, or abnormal liver function tests. 
This could indicate that your liver may be harmed by TIMP-GLIA. Your blood tests may show 
that you have decreases in the numbers of white blood cells, platelets, and red blood cells and 
increases in the number of cells that turn into red blood cells ("reticulocytes"). This could indicate 
that your spleen and bone marrow may be harmed by TIMP-GLIA.
Since the TIMP-GLIA contains a gliadin extract, there is a possibility that you may experience 
worsening of your celiac disease symptoms (nausea, vomiting, bloating, diarrhea, abdominal pain, 
fatigue) after receiving the study medicine. TIMP-GLIA is designed to present gliadin in a 
noninflammatory way, but individual responses may vary.
All medications have a risk of an allergic reaction. Seek immediate medical help if you have any of 
the following signs of a serious allergic reaction: swelling of the face, mouth, lips, gums, tongue,

or neck. Other allergic reactions may include rash, hives, or blisters. Tell your study doctor as soon 
as possible if any of these reactions happen.
There may be other side effects of TIMP-GLIA that we don’t know about.  Tell your study doctor 
or study staff as soon as possible about all side effects that you have. If you are not honest about 
your side effects, it may not be safe for you to stay in the study.”

and 4
Added:
At the time of this amended 
protocol (Version 9), 
TIMP-GLIA has been given as a 
single infusion to 17 subjects 
with celiac disease (Part A of this 
study).  At the highest dose 
tested, approximately 650 mg, 2 
of 4 subjects experienced a 
moderate IRR.  For one of the 
subjects the infusion was 
stopped and the signs and 
symptoms went away 
immediately.  For the second 
subject, the infusion was stopped 
and the signs and symptoms 
went away immediately, and the 
infusion was restarted at a 
slower rate.  The subject 
completed the infusion without 
any other problems.
Signs and symptoms of IRR to 
TIMP-GLIA have included 
flushing (warm feeling or 
reddening of face, back and/or
chest), rash, nausea, vomiting, 
back pain, low or high blood 
pressure, or increase in heart 
rate.  These symptoms were 
either mild or moderate.  All

8.7.1 Blood Collection for PK, ¶2, 
3, 4 
Deleted:
Scheduled blood collections for 
TIMP-GLIA measurement for 
pharmacokinetics are to occur at 
30 minutes and at 35 minutes 
relative to start of infusion. The 
former represents the planned 
end-of-infusion collection. 
Because the clearance from the 
blood compartment is expected to 
be rapid, the latter blood collection 
facilitates the characterization of 
Tmax, even in the event of a brief 
unforseen procedural delays.
In the event that the study drug 
infusion is interrupted (particularly 
> 5 minutes), the scheduled 
collection at 35 minutes post 
infusion start time should be 
postponed until the actual 
end-of-infusion. This should be 
documented in a similar manner as 
any other blood collection falling 
outside the defined window.
The 30-minute collection should 
proceed relative to the infusion 
start time, with corresponding 
documentation that it does not 
represent the end-of-infusion. In 
addition, the volume of study drug 
administered at 30 minutes (as 
indicated by the infusion pump or 
estimated, as feasible) is to be 
recorded in the source.

completed Study Day 3.  If the committee thinks it is safe, the next group of 2 subjects will 
receive the next higher dose (e.g., 4 mg/kg).

Part B
At this point, the study will enter 
Part B.  Eligible subjects (at least 3 
CD subjects) will receive the 
maximum safe and tolerable dose 
of TIMP-GLIA identified from 
Part A.  TIMP-GLIA will be 
administered as a single IV 
infusion, 7 days apart, on Day 1 
and on Day 8. Each subject in Part 
B will be observed in clinic for 48 
hours after each dose. 
At least 168 hours (7 days) will 
elapse after the second dose and 
safety confirmed before the next 
subject will be dosed.  If 
dose-limiting toxicity occurs in 1 
of the 3 subjects in Part B, the 
DMC may decide to increase 
enrollment by 3 subjects or to 
enroll another cohort of 3 subjects 
at a lower dose level. The DMC 
may recommend that up to a total 
of 12 subjects may be accrued to 
better define the relationship 
between dose and emerging safety 
signals.

Rationale
Part B
Part B will evaluate 2 doses of 
TIMP-GLIA administered on 
Days 1 and 8.  Two subjects will 
be enrolled into each of 3 cohorts 
at dose levels of 2, 4, and 8 mg/kg 
up to a maximum of 650 mg. Dose 
escalation will proceed only if 
Study Stopping Criteria (“Study 
Stopping Rules”) are not met. If 
dose-limiting toxicity (DLT) 
occurs in 1 of the 2 subjects in a 
cohort, the DMC may decide to 
increase enrollment at the same 
dose level by 2 subjects. (2+2

Bullet 9
Changed/Added:
-
In Part A, when all subjects in 
a dose cohort complete 
procedures through 168 hours 
post dose, the overall safety 
and tolerability data (AEs, vital 
signs, 12-lead ECGs, clinical 
laboratory tests, cytokines) for 
the current cohort and available 
cumulative AE data from 
previous cohorts will be 
reviewed by the DMC who will 
determine the progression or 
termination of dosing. In Part 
B, the DMC will review all 
safety date from a cohort 
when the last subject in a 
cohort has completed 
procedures through 48 
hours.
Part A remains the same.
The 2 infusion reactions observed 
in Part A at 8 mg/kg occurred 
within minutes of the start of the 
infusion.  Symptoms for both 
subjects resolved within an hour 
(maximum) of stopping the 
infusion.  Forty-eight hours is a 
sufficient waiting period to observe 
an infusion reaction and its 
resolution.

Changed and Added:
This In Part A, this design model
will allow the study proceed more
quickly through the lowest doses 
at which little or no effect is 
anticipated to be observed….    In 
Part B, the accelerated model 
allows the study to proceed at 
the lower doses at which little or

2.3Rationale for the Trial Design, 
¶5
Changed:
Part B will be a repeat-dose study 
with 3 2 subjects who will receive 
the first infusion on Day 1 and the 
second infusion on Day 8. The 
dose selection for Part B will be 
based on the emerging safety and 
tolerability data from Part A as 
decided by the DMC. If a 
dose-limiting toxicity occurs in 1 
of the 3 2 subjects in Part B, the 
DMC may decide to enroll an 
additional 3 2 subjects at the same 
dose to confirm ambiguous safety 
or tolerability findings. Depending 
upon the emerging safety data, 
they may also recommend 
enrollment of an additional cohort 
of 3 subjects at a lower dose to 
discern the safety profile of repeat 
dosing….
