The study is a multi-center, randomized, double-blind, placebo-controlled, adaptive study. 
Approximately 80 clinically or histologically diagnosed adult non-cirrhotic presumed NASH 
patients who meet study eligibility criteria will be enrolled and randomized at an overall ratio of 
2:1 into 3 dose groups and placebo across 2 parts of the study.  
Part 1  
In Part 1, approximately 30 patients will receive 10 mg TERN-201 (n = 20) or matching placebo 
(n = 10) orally once daily, for 12 weeks.  
In Part 1 of the study, approximately 12 randomized patients will take part in an intensive PK 
and PD collection after the first dose (Week 0/Day 1), at Week 6, and after the last dose of study 
drug (Week 12). Randomization will ensure approximately 8 patients in the TERN-201 group 
and approximately 4 patients in the placebo group are assigned to the PK/PD sub-study. Patients 
who are not participating in the PK/PD sub-study will have trough PK/PD sampling only. 
Part 2 may be enrolled based on an interim analysis, as follows: 
An interim analysis will be performed after all patients in Part 1 have completed Week 6 
assessments. Interim PK and PD data will be assessed. Blinded safety data will also be reviewed. 
Enrollment of cohorts to assess 4 mg and up to 20 mg TERN-201 may be initiated per the 
following criteria: 
x TERN-201 4 mg: 
o If robust VAP-1/SSAO activity suppression is observed  and available PK from 
Part 1 suggests that a lower dose may also possibly lead to robust VAP-1/SSAO 
activity suppression, enrollment in Part 2 with 4 mg TERN-201 may be initiated. 
x TERN-201 up to 20 mg: 
o If safety data indicates 10 mg TERN-201 is overall safe and well-tolerated, and 
available PK from Part 1 predicts that targeted exposures for a dose up to 20 mg 
will be below an upper limit of 5400 ng•hr/mL for AUC0-24hr and 768 ng/mL for 
Cmax, enrollment in Part 2 with a dose up to 20 mg TERN-201 may be initiated. 
Part 2  
In Part 2, if initiated, approximately 50 patients will receive 4 mg TERN-201 (n = 20), and/or up 
to 20 mg TERN-201 (n = 20), or matching placebo (n = 10) orally once daily, for 12 weeks.

In Part 2 of the study, approximately 15 randomized patients will take part in an intensive PK 
and PD collection after the first dose (Week 0/Day 1), at Week 6, and after the last dose of study 
drug (Week 12). Randomization will ensure approximately 6 patients at each TERN-201 dose 
level and approximately 3 patients in the placebo group are assigned to the PK/PD sub-study. 
Patients who are not participating in the PK/PD sub-study will have trough PK/PD sampling 
only. 
The total duration of study participation will be approximately 22 weeks, consisting of a 6-week 
Screening Period, a 12-week Treatment Period and a 4-week Follow-up Period.  
Number of Patients: 
Approximately 80 patients will be randomly assigned to treatment with TERN-201 capsule or 
matching placebo. 
Patients who are randomized but do not receive study drug for any reason may be replaced. In 
addition, patients who discontinue treatment early for reasons other than safety (i.e., withdrawal 
of consent, lost to follow-up, patient relocated, etc.) may also be replaced. Replacement patients 
will receive the same treatment assignment as the patient that discontinued treatment early. 
Study Centers Planned:  
Up to 15 centers in the United States.

Introduction 
2.1. 
Overview of NASH and Role of VAP-1/SSAO in Disease 
Terns is developing TERN-201, an investigational, potent, and highly selective, irreversible 
covalent inhibitor of human vascular adhesion protein-1(VAP-1)/semicarbazide-sensitive amine 
oxidase for the treatment of patients with non-alcoholic steatohepatitis (NASH).  
NASH is an advanced form of non-alcoholic fatty liver disease (NAFLD), the most common 
cause of chronic liver disease in North America (Chalasani 2018). NASH is characterized by the 
presence of hepatic inflammation and hepatocellular ballooning, with or without fibrosis. NASH 
is a progressive condition that can lead to cirrhosis, decompensated liver disease, and increased 
risk for hepatic carcinoma and liver-related mortality (Ekstedt 2015). Currently, there are no 
approved therapies for the treatment of NASH. With an aging population and the emergence of 
overlapping epidemics of obesity, diabetes, and dyslipidemia/metabolic syndrome, NAFLD and 
NASH have increased greatly in prevalence (Andronescu 2018), posing a significant healthcare 
challenge. 
VAP-1/SSAO is a cellular adhesion protein and ectoenzyme expressed on the vascular 
endothelium that has long been recognized as a mediator of leukocyte adhesion and 
extravasation in the setting of inflammation (Salmi 2019). The enzymatic activity of VAP-1 
further contributes to inflammation and oxidative stress by converting primary amines to 
aldehyde, ammonia, and hydrogen peroxide. VAP-1 levels are increased in the liver tissue and 
blood of patients with NASH and circulating VAP-1, termed soluble VAP-1 (sVAP-1), is 
independently associated with fibrosis stage (Weston 2015). Genetic and pharmacology studies 
indicate VAP-1 deficiency or inhibition attenuate steatosis, inflammation, and fibrosis in NASH 
models. VAP-1 deficiency attenuates carbon tetrachloride (CCl4)-induced hepatic fibrosis and 
VAP-1 knockout mice exhibit reduced hepatic steatosis and fibrosis when fed a western lifestyle 
diet. Moreover, treatment with a VAP-1 antibody reduces inflammation, steatosis, and fibrosis in 
a methionine choline–deficient diet mouse model of NASH (Weston 2015).  
Based on these observations, VAP-1 inhibition is anticipated to reduce inflammation and fibrosis 
in NASH patients. This novel mechanism provides a potential opportunity to treat NASH, a 
disease with significant unmet medical needs.  
Of note, historically, VAP-1 has also been referred to as SSAO due to its sensitivity to inhibition 
by semicarbazide, a property that distinguishes it from flavin adenine dinucleotide (FAD)-
containing monoamine oxidases (e.g., MAO-A and MAO-B) (Smith 1998). In this document, the

terms VAP-1 and SSAO (or VAP-1/SSAO) are used interchangeably. Additional information on 
nomenclature is available in the Investigator’s Brochure. 
2.2. 
VAP-1/SSAO Inhibition in NASH and TERN-201 Background 
VAP-1 has been identified as a target for NASH due to the inflammatory component of NASH 
pathogenesis, association of increased VAP-1 levels in NASH patients, and nonclinical studies 
supporting potential benefit in NASH from VAP-1/SSAO deficiency or suppression 
(Section 2.1). One other VAP-1/SSAO inhibitor has been studied in NASH patients 
(ClinicalTrials.gov Identifier: NCT03166735). Pharmaxis (Frenchs Forest, AUS) identified an 
oral VAP-1 inhibitor, BI 1467335 (formerly PXS-4728A), which was advanced into clinical 
development for NASH by Boehringer Ingelheim. Preliminary data suggest dose-dependent 
reductions in alanine aminotransferase (ALT) and CK-18 with 12-weeks of treatment with BI 
1467335, and an overall reassuring safety profile in NASH patients (ClinicalTrials.gov Identifier: 
NCT03166735). In addition to its activity against VAP-1, BI 1467335 also inhibits monoamine 
oxidase B (MAO-B) (Schilter 2015), albeit to a lesser extent, with potential implications for 
drug-drug interactions associated with monoamine oxidase inhibition. In addition to NASH, 
VAP-1 inhibitors have also been explored for other indications including kidney disease. In a 
phase 2 study (ALBUM, ClinicalTrials.gov Identifier: NCT02358096), the VAP-1 inhibitor 
ASP8232 (Astellas Pharma) was effective at reducing albuminuria in patients with diabetic 
kidney disease, suggesting the possibility of benefit outside of liver, perhaps attributable to 
endothelial effects (de Zeeuw 2018). 
TERN-201 is a potent, irreversible, highly specific inhibitor of VAP-1/SSAO, formulated for 
oral administration in a capsule form. Nonclinical studies have demonstrated that TERN-201 is 
efficacious in models of liver fibrosis and NASH, and does not have activity against monoamine 
oxidase A or B. 
TERN-201 has been evaluated in an extensive nonclinical program, including PK, safety

in duration. TERN-201 has also been evaluated in a first-in-human (FIH) study (N=61), where it 
was found to be overall safe and well-tolerated.  
Below is a brief summary of these studies. Detailed results are available in the TERN-201 
Investigator’s Brochure.

2.2.2. 
Clinical Studies of TERN-201 
The initial, FIH Phase 1 clinical study, TERN201-US-A101, was a double-blind, randomized, 
placebo-controlled study to investigate the safety, tolerability, pharmacokinetics (PK), and 
pharmacodynamics (PD) of single and multiple ascending oral doses of TERN-201 in healthy 
participants. The study was also designed to investigate the effect of food (high-fat/high-calorie 
meal) on the PK of TERN-201. Study TERN201-US-A101 was comprised of 3 parts. In Part A, 
4 single-ascending dose (SAD) cohorts (8 participants each [6 TERN-201, 2 placebo]) were 
completed, in which participants received oral TERN-201 or matching placebo doses of 1, 3, 6, 
or 10 mg. A fifth SAD cohort (20 mg) was planned but not enrolled due to public health 
restrictions resulting from the Coronavirus Disease 2019 (COVID-19) pandemic. In Part B, 
3 multiple-ascending dose (MAD) cohorts (8 participants each [6 TERN-201, 2 placebo]) were 
completed, in which participants received oral TERN-201 or matching placebo daily doses of 
1 mg for 7 days, 4 mg for 7 days, or 10 mg for 14 days. Part C, the Food Effect cohort, was 
initiated with 5 of the 16 planned participants enrolled; however, enrollment was discontinued 
early due to the -19 pandemic. The 5 participants enrolled in Part C received both doses of 
TERN-201 10 mg (single doses on Days 1 and 8, fed and fasted) as planned in the study 
protocol. 
During the study, no safety or tolerability concerns were identified, and no predefined stopping 
criteria were met. All AEs were Grade 1 or 2 (National Cancer Institute [NCI] Common 
Terminology Criteria for Adverse Events [CTCAE] Version 5.0) in severity. All AEs in 
participants who received TERN-201 were reported to be mild in severity. With exception of 
mild contact dermatitis at the site of electrocardiogram (ECG) leads that was considered 
unrelated to study drug, and headache (2 participants), all AE types were isolated to a single 
participant. There were no serious AEs, deaths, or AEs that led to discontinuation of study drug

in any cohort. Laboratory, vital signs, and other safety assessments including EEG monitoring 
showed no notable findings across individual participants or cohorts.  
Plasma exposures to TERN-201 were greater than dose proportional. TERN-201 was rapidly 
cleared from plasma. Steady state was achieved in the highest dose group (10 mg) after Day 7 of 
dosing. The half-life of TERN-201 increased with dose, suggesting saturable, target-mediated 
clearance.  
Single and multiple doses of TERN-201 significantly suppressed plasma total amine oxidase 
activity at all doses studied. Using an exploratory assay to assess the effect of TERN-201 on 
VAP-1/SSAO-specific amine oxidase activity in the plasma, near complete inhibition (>80% 
with 1 mg, > 90% with 10 mg) was observed after only a single dose on Day 1 (achieved within 
4 hours after dosing) with sustained suppression over the dosing period in MAD cohorts. Dose-
dependent increases in methylamine, an endogenous substrate of VAP-1/SSAO predicted to 
increase upon VAP-1/SSAO inhibition, were observed after the first dose of TERN-201 and 
continued to increase in a dose-dependent manner after multiple doses of TERN-201.  
Based on the exploratory assessment on plasma PK of two TERN-201 metabolites, TRN-001021 
and TRN-001744, the percentages of either metabolite AUC relative to the total TERN-201-
related plasma AUC (sum of TERN-201, TRN-001021, and TRN-001744) were calculated. 
Median TRN-001021 AUC was <10% and 13.7% of the total plasma AUC associated with 
TERN-201 in the 4 mg and 10 mg groups, respectively. Median TRN-001744 AUC was 11.5% 
and <10% of the total plasma AUC associated with TERN-201 in the 4 mg and 10 mg groups, 
respectively. 
Additional details on Study TERN201-US-A101 are available in the Investigator’s Brochure.

The protocol has been designed to minimize the risk to patients. Patients will be monitored to 
detect AEs during the study and will be followed appropriately to ensure resolution of AEs. 
Standard hematology, chemistry, urinalysis, lipid levels, and ECGs will be obtained and 
monitored for abnormalities. Prior to administration of a dose up to 20 mg TERN-201, available 
PK from the 10 mg cohort will be assessed to predict that projected exposures are below the 
limits noted above. 
Taking into account the measures taken to minimize risk to patients in this study, the potential 
risks identified in association with TERN-201 are justified by the anticipated benefits that may 
be afforded to patients with NASH.

Study Design 
4.1. 
Overall Design 
The study is a multi-center, randomized, double-blind, placebo-controlled, adaptive study. 
Approximately 80 clinically or histologically diagnosed adult non-cirrhotic presumed NASH 
patients who meet study eligibility criteria will be enrolled and randomized at an overall ratio of 
2:1 in up to 3 dose groups and placebo across 2 parts of the study. 
Part 1  
In Part 1, approximately 30 patients will receive 10 mg TERN-201 (n = 20) or matching placebo 
(n = 10) orally once daily, for 12 weeks. Part 2 may be enrolled based on an interim analysis, as 
follows: 
In Part 1 of the study, approximately 12 randomized patients will take part in an intensive PK 
and PD collection after the first dose (Week 0/Day 1), at Week 6, and after the last dose of study 
drug (Week 12). Randomization will ensure approximately 8 patients in the TERN-201 group 
and approximately 4 patients in the placebo group are assigned to the PK/PD sub-study. Patients 
who are not participating in the PK/PD sub-study will have trough PK/PD sampling only. 
An interim analysis will be performed after all patients in Part 1 have completed Week 6 
assessments. Interim PK and PD data will be assessed. Blinded safety data will also be reviewed. 
Enrollment of cohorts to assess 4 mg and up to 20 mg TERN-201 may be initiated per the 
following criteria: 
x TERN-201 4 mg: 
o If robust VAP-1/SSAO activity suppression is observed and available PK from 
Part 1 suggests that a lower dose may also possibly lead to robust VAP-1/SSAO 
activity suppression, enrollment in Part 2 with 4 mg TERN-201 may be initiated. 
x TERN-201 up to 20 mg: 
o If safety data indicates 10 mg TERN-201 is overall safe and well-tolerated, and 
available PK from Part 1 predicts that targeted exposures for a dose up to 20 mg 
will be below an upper limit of 5400 ng•hr/mL for AUC0-24hr and 768 ng/mL for 
Cmax, enrollment in Part 2 with a dose up to 20 mg TERN-201 may be initiated. 
Part 2  
In Part 2, if initiated, approximately 50 patients will receive 4 mg TERN-201 (n = 20), and/or up 
to 20 mg TERN-201 (n = 20), or matching placebo (n = 10) orally once daily, for 12 weeks.

In Part 2 of the study, approximately 15 randomized patients will take part in an intensive PK 
and PD collection after the first dose (Week 0/Day 1), at Week 6, and after the last dose of study 
drug (Week 12). Randomization will ensure approximately 6 patients at each TERN-201 dose 
level and approximately 3 patients in the placebo group are assigned to the PK/PD sub-study.  
The total duration of study participation will be approximately 22 weeks, consisting of a 6-week 
Screening Period, a 12-week Treatment Period and a 4-week Follow-up Period.  
4.2. 
Scientific Rationale for Study Design 
Collectively, results from nonclinical studies and FIH study, TERN201-US-A101, support the 
development of TERN-201 as an orally administered VAP-1/SSAO inhibitor to reduce 
inflammation and fibrosis in the liver of patients with NASH. TERN-201 provides a promising 
potential treatment for NASH, a disease with significant unmet medical need. 
 
 
 
 
  
The initiation of Part 1 of the study will evaluate the highest dose studied in the FIH study (10 
mg TERN-201), which was safe and well-tolerated and will allow for the PD effect of TERN-
201 (e.g., inhibition of plasma VAP-1/SSAO activity) to be assessed in the NASH population. 
 
 
 
 
The placebo-controlled nature of the study will allow for a control group to characterize the 
safety and preliminary efficacy of TERN-201 in a NASH population. Given the efficacy of 
TERN-201 has not yet been confirmed, there is no clear detriment to patients who may be 
randomized to receive placebo rather than active treatment in this study. 
The study will enroll a non-cirrhotic presumed NASH population based on clinical 
characteristics and imaging (without a requirement for liver biopsy), to characterize safety and 
efficacy in this population. While there is not an expected risk of neurological toxicity at the 
clinical doses proposed based nonclinical toxicity studies and the FIH study, patients with a 
history of seizures and select other co-morbidities will be excluded toavoid interference from 
disease processes in the safety assessment of TERN-201 in this study.

4.3. 
Justification for Dose 
Doses for this study were based on results from the FIH Phase 1 study, TERN201-US-A101, 
which evaluated 4 SAD cohorts of TERN-201 or matching placebo at 1 mg, 3 mg, 6 mg, or 
10 mg, and 3 MAD cohorts of TERN-201 or matching placebo at 1 mg for 7 days, 4 mg for 
7 days, or 10 mg for 14 days.  
In the FIH study, single or multiple doses of TERN-201 resulted in rapid inhibition of plasma 
amine oxidase activity, with sustained inhibition during 14 days of dosing. TERN-201 
demonstrated a favorable safety profile and was overall well-tolerated at all doses studied 
(Section 2.2.2). 
Part 1 of this study assesses 10 mg of TERN-201, the highest dose studied in the FIH study. In 
the FIH study, this dose led to >90% suppression of plasma VAP-1/SSAO-specific amine 
oxidase activity in healthy participants. NASH patients are expected to have a higher baseline 
level of VAP-1, and thus the PD effect of TERN-201 in NASH patients may differ from healthy 
participants. A higher dose of up to 20 mg may be enrolled based on assessment of safety and 
PK with the 10 mg dose, and a lower dose of 4 mg may be enrolled based on observation of a 
robust PD effect of TERN-201 on plasma VAP-1/SSAO activity in the 10 mg cohort, thus 
minimizing the number of patients exposed until the PK and PD effects of TERN-201 can be 
confirmed in Part 1 of the study.  
Toxicity and safety pharmacology studies support starting with the 10 mg dose and enrolling a 
higher dose up to 20 mg.

The Investigator or designee must provide acknowledgement of receipt of each shipment of 
study drug including appropriate temperature conditions have been maintained during transit for 
all study drug received and any discrepancies are reported and resolved before use of the study 
drug. 
Only patients enrolled in the study may receive study drug and only authorized site staff may 
supply or administer study drug. All study drug must be stored in a secure, environmentally 
controlled, and monitored (manual or automated) area in accordance with the labeled storage 
conditions with access limited to the Investigator and authorized site staff. 
The Investigator, institution, or the head of the medical institution (where applicable) is 
responsible for study drug accountability, reconciliation, and record maintenance (i.e., receipt, 
reconciliation, and final disposition records). 
Further guidance and information for the final disposition of unused study drugs are provided in 
the Pharmacy Manual.  
6.4. 
Measures to Minimize Bias: Randomization and Blinding 
Patients will be randomized to TERN-201 or placebo using an Interactive Web Response System 
(IWRS). Before the study is initiated, the log-in information and directions for the IWRS will be 
provided to each site. 
Approximately 80 patients will be enrolled in this study. In Part 1, approximately 30 patients will 
be randomized at a ratio of 2:1 to receive 10 mg TERN-201 (n = 20) or matching placebo (n = 
10). In Part 2, if initiated, approximately 50 patients will be randomized at a ratio of 2:1 to 
receive 4 mg TERN-201 (n = 20), and/or 20 mg TERN-201 (n = 20), or matching placebo (n = 
10). Randomization will be stratified by Screening MRI cT1 values  900 ms versus > 900 ms.

In Part 1 of the study, approximately 12 randomized patients will take part in an intensive PK 
and PD collection after the first dose and after the last dose of study drug. Randomization will 
ensure approximately 6 patients in the TERN-201 group and approximately 6 patients in the 
placebo group are assigned to the PK/PD sub-study. Patients who are not participating in the 
PK/PD sub-study will have trough PK/PD sampling only. 
In Part 2 of the study, approximately 15 randomized patients will take part in an intensive PK 
and PD collection after the first dose and after the last dose of study drug. Randomization will 
ensure approximately 6 patients at each TERN-201 dose level and approximately 3 patients in 
the placebo group are assigned to the PK/PD sub-study. Patients who are not participating in the 
PK/PD sub-study will have trough PK/PD sampling only. 
Investigators, patients, all study personnel, and the Sponsor will remain blinded to each patient’s 
assigned dose group throughout the course of the study, unless otherwise specified in 
Section 6.4.1. Study drug will be dispensed at the study visits as summarized in Schedule of 
Activities. Returned study drug should not be re-dispensed to patients.  
A planned interim analysis will be conducted after all patients in Part 1 have completed Week 6 
assessments, and an administrative interim analysis may be conducted after the completion of 
Part 1 of the study. For these analyses, the study team will be blinded at the individual patient 
level, with designated personnel responsible for producing the summary results. The details will 
be addressed in a separate plan.  
6.4.1. 
Unblinding 
Treatment assignment may be unblinded if knowing the patient’s treatment assignment would 
affect immediate medical management of the patient. The IWRS will be programmed with blind-
breaking instructions. In case of an emergency, the Investigator has the sole responsibility for 
determining if unblinding of a patient’s intervention assignment is warranted. Patient safety must 
always be the first consideration in making such a determination. If the Investigator decides that 
unblinding is warranted, the Investigator should make every effort to contact the Sponsor prior to 
unblinding a patient’s intervention assignment unless this could delay emergency treatment of 
the patient. If a patient’s intervention assignment is unblinded, the Sponsor must be notified 
within 24 hours after breaking the blind. The date and reason that the blind was broken must be 
recorded in the source documentation and case report form, as applicable. 
Any unblinding of Sponsor personnel for expedited reporting of suspected unexpected serious 
adverse reactions (SUSARs) or other reasons including planned interim analyses will be 
addressed in a separate plan.

6.4.2. 
Patient Enrollment and Study Drug Assignment 
It is the responsibility of the Investigator to ensure that patient eligibility is confirmed prior to 
randomization. Documentation of the personally signed and dated informed consent of each 
patient, using the study-specific ICF, is required before initiating the Screening Period.  
After written informed consent has been obtained, the patient’s identification number will be 
obtained from the IWRS. Once eligibility to participate has been established, the randomized 
treatment assignment will be obtained from the IWRS. 
6.5. 
Study Drug Compliance 
Patients will be dispensed study during their study visits and will self-administer study drug at 
home. Patients must be in fasted state for at least 8 hours prior to study drug administration. At 
all study visits, study drug administration will be observed at the study site. Patients should be 
instructed to hold their dose of study drug on visit days until all visit procedures have been 
completed. On all other days, patients will self-administer the study drug orally once daily in the 
morning on an empty stomach, after an 8 hour fast. 
Compliance will be assessed by direct questioning and counting returned capsules during the 
study visits and documented in the source documents and electronic case report form (eCRF). 
Deviation(s) from the prescribed dosage regimen should be recorded in the eCRF.   
If a patient is required to be quarantined due to active infection of COVID-19 or exposure to 
COVID-19, or is otherwise unable to visit the site due to COVID-19, study drug may be mailed 
to the patient or made available via another appropriate mechanism (i.e., curbside pickup, etc). 
Patients will be asked to maintain records of self-administered drug on non-study visit days. A 
record of the number of study drug capsules dispensed to and taken by each patient must be 
maintained and reconciled with study drug and compliance records at the site. Study drug start 
and stop dates, including dates for delays will also be recorded in the eCRF. 
6.6. 
Concomitant Therapy

6.8. 
Dose Interruptions  
On all non-study visit days, patients will self-administer the study drug orally once daily in the 
morning, on an empty stomach, after an 8 hour fast. If a patient forgets to self-administer study 
drug in the morning on a given day, the dose can be taken on the same day when the patient 
remembers, with the exception below:  
x For patients participating in the PK/PD sub-study, drug must be self-administered the 
morning of the day prior to the Week 6 and Week 12 visits. If not, the visit should be re-
scheduled for the following day. 
If a patient forgets to self-administer study drug on a given day, it will be designated a missed 
dose. Dosing may continue orally once daily according to the protocol schedule after a missed 
dose.  
If study drug is discontinued or suspended for safety reasons considered related to study drug, 
dosing should not be resumed without consultation with the Medical Monitor. Information on 
stopping study drug for patients due to safety/other reasons is detailed in Section 7.  
6.8.1. 
Dose Interruptions due to COVID-19 
If a patient requires home quarantine due to SARS-CoV-2 infection or exposure, or due to 
COVID-19 symptoms, the patient may continue study drug provided that appropriate safety 
follow-up is possible, and that hospitalization is not required. Home health care visits may be 
conducted to continue study assessments in the patient’s home where feasible, and/or remote 
visits via telephone, telemedicine, or other appropriate virtual communication may be substituted 
for a visit to the site. Sites should discuss the mechanism for safety follow-up with the Medical 
Monitor. 
If a patient has symptoms of COVID-19 requiring hospitalization, study drug must be 
discontinued during hospitalization. A case-by-case assessment of whether to resume study drug 
can be done upon discharge. Dosing should not be resumed without consultation with the 
Medical Monitor. The patient should be encouraged to remain in the study to be evaluated during 
the Follow-Up Period.  
6.9. 
Intervention after the End of the Study 
No further interventions are planned after the end of the study.

Discontinuation of Study Drug and Patient 
Discontinuation/Withdrawal 
7.1. 
Discontinuation of Study Drug 
Study drug must be discontinued for an individual patient in the following instances:  
x If an AE of Grade 3 or above (National Cancer Institute (NCI) CTCAE 5.0) occurs and 
is considered related to study drug as judged by the Investigator per the guidance in 
Appendix 6 
x Symptoms of COVID-19 requiring hospitalization 
x Change in clinical status that, in the judgement of the Investigator compromises the 
patient’s ability to continue treatment or is not considered to be in the patient’s best 
interest  
x Patient request to discontinue study drug for any reason 
x Pregnancy during the study (refer to Appendix 7) 
x Sponsor discretion  
x Discontinuation of the study at the request of the Sponsor, a regulatory agency, or 
Institutional Review Board (IRB)/Independent Ethics Committee (IEC) 
Resumption of study drug may be considered in discussion with the Medical Monitor and 
Sponsor. 
If one of the following situations occurs and is considered related to the study drug without 
alternative etiology, study drug may be discontinued at the discretion of the Investigator and the 
Medical Monitor should be informed (with repeat test performed within 48-72 hours once initial 
abnormality is detected): 
x ALT or AST > 8 × ULN  
x ALT or AST > 5 × ULN for more than 1 week, confirmed with a repeat assessment  
x ALT or AST > 2 × Baseline with the appearance of fatigue, nausea, vomiting, right 
upper quadrant pain or tenderness, fever, rash, and/or eosinophilia > 5% 
x ALT or AST > 2 × Baseline and total bilirubin > 2 × ULN or INR > 1.5 for more than 1 
week, confirmed with a repeat assessment 
In addition, Investigators may permanently discontinue study drug at their discretion due to 
patient non-compliance with study drug or study assessments. 
If study drug is permanently discontinued, the patient will remain in the study to be evaluated 
during the Follow-Up Period. See the Schedule of Activities for data to be collected at the time 
of discontinuation of study drug and follow-up and for any further evaluations that need to be 
completed.

7.2. 
Patient Discontinuation/Withdrawal from the Study 
A patient may withdraw from the study at any time at his/her own request or may be withdrawn 
at any time at the discretion of the Investigator for safety, behavioral, compliance, or 
administrative reasons.  
Patients discontinuing the study at any time for any reason prior to Week 12 (Early Termination) 
should complete the early termination (ET) visit as soon as feasible and return for a Follow-Up 
approximately 4 weeks after the last dose of study drug. See the Schedule of Activities for data 
to be collected at the time of study discontinuation and follow-up and for any further evaluations 
that need to be completed. 
If the patient withdraws consent for disclosure of future information, the Sponsor may retain and 
continue to use any data collected before such a withdrawal of consent. 
If a patient withdraws from the study, he/she may request destruction of any samples taken and 
not tested, and the Investigator must document this in the site study records. 
7.3. 
Lost to Follow up 
A patient will be considered lost to follow-up if he or she repeatedly fails to return for a 
scheduled visit and is unable to be contacted by the study site. 
The following actions must be taken if a patient fails to return to the clinic for a required study 
visit: 
x 
The site must attempt to contact the patient and reschedule the missed visit as soon as 
possible, counsel the patient on the importance of maintaining the assigned visit 
schedule, and ascertain whether or not the patient wishes to and/or should continue in 
the study. 
x 
Before a patient is deemed lost to follow up, the Investigator or designee must make 
every effort to regain contact with the patient (where possible, 3 telephone calls and, if 
necessary, a certified letter to the patient’s last known mailing address or local 
equivalent methods). These contact attempts should be documented in the patient’s 
medical record. 
x 
Should the patient continue to be unreachable, he/she will be considered to have 
withdrawn from the study.  
Discontinuation of specific sites or of the study as a whole are addressed in Section 10.1.8.

Study Assessments and Procedures 
Study procedures and their timing are summarized in the Schedule of Activities. Protocol 
waivers or exemptions are not allowed. 
Adherence to the study design requirements, including those specified in the Schedule of 
Activities, is essential and required for study conduct. 
All screening evaluations must be completed and reviewed to confirm that potential patients 
meet all eligibility criteria. The Investigator will maintain a screening log to record details of all 
patients screened and to confirm eligibility or record reasons for screening failure, as applicable. 
The maximum amount of blood collected from each patient over the duration of the study is not 
expected to exceed 650 mL. Repeat or unscheduled samples may be taken for safety reasons or 
for technical issues with the samples. 
If a patient requires home quarantine due to SARS-CoV-2 infection or exposure, or due to 
COVID-19 symptoms or other associated concern with attending an in-person study visit; home 
health care visits may be conducted to continue study assessments in the patient’s home where 
feasible, and/or remote visits via telephone, telemedicine, or other appropriate virtual 
communication may be substituted for a visit to the site. 
8.1. 
Study Assessments 
Planned time points for all safety assessments are provided in the Schedule of Activities.  
8.1.1. 
Demographics 
Demographic data includes age, sex, and race/ethnicity.  
8.1.2. 
Height and Weight 
Height and weight are collected at Screening and will be used to calculate BMI. Waist 
circumference is also measured at Screening. Only weight is collected on other days specified in 
the Schedule of Activities.  
Waist (abdominal) circumference is measured with measuring-tape position as follows (National 
Heart, Lung, and Blood Institute 2000): The upper hip bone and the top of the right iliac crest 
should be located and measuring tape placed in a horizontal plane around the abdomen at the 
level of the iliac crest. The tape should be snug but should not compress the skin, and should be 
parallel to the floor, at the time of measurement. The measurement should be taken at the end of 
a normal expiration.

8.1.3. 
Medical History 
Medical and surgical history, including details of illnesses and allergies, date(s) of onset, whether 
condition(s) is currently ongoing, and medication history, including alcohol use, will be collected 
for all patients at Screening.  
8.1.4. 
Physical Examinations 
A complete physical examination will include assessments of general appearance, 
cardiovascular, respiratory, abdomen, head and neck (including ears, eyes, nose, throat, and 
thyroid), lymph nodes, musculoskeletal systems, and neurological exam.  
A targeted physical examination may be conducted to evaluate reported current or prior AEs, 
symptoms reported by the patient, or abnormal laboratory readouts.  
Investigators should pay special attention to clinical signs related to previous serious illnesses. 
8.1.5. 
Vital Signs 
Temperature, pulse rate, respiratory rate, and blood pressure will be assessed and maintained in 
source documentation.  
Blood pressure and pulse measurements will be assessed with a completely automated device. 
Manual techniques will be used only if an automated device is not available. 
Blood pressure and pulse measurements should be preceded by at least 5 minutes of rest for the 
patient in a quiet setting without distractions (e.g., television, cell phones). 
8.1.6. 
Electrocardiograms 
Single 12-lead ECGs will be obtained as outlined in the Schedule of Activities using an ECG 
machine that automatically calculates the heart rate and measures PR, QRS, and QT intervals. 
QTc will be calculated using the formula outlined in Appendix 4. 
An ad hoc ECG should be performed in the instance of patient-reported symptoms considered 
potentially cardiac in nature such as chest pain/pressure, palpitations, dizziness, shortness of 
breath, or report of patient recently seeking medical care for such symptoms (e.g., emergency 
room visit); cardiology consult should be obtained based on the clinical judgement of the 
Investigator.  
The Investigator will review the ECGs for any clinically significant abnormalities.

8.1.7. 
Clinical Laboratory Assessments 
See Appendix 1 for the list of clinical laboratory tests to be performed and the Schedule of 
Activities for the timing and frequency. 
The Investigator must review the laboratory report, document this review, and record any AEs 
per the guidance in Appendix 6. The laboratory reports must be filed with the source documents.  
Clinically significant laboratory shifts, or any clinically significant abnormalities considered 
possibly related to study drug in the opinion of the Investigator, should be repeated within 48-72 
hours and followed to resolution or until stable. 
All protocol-required laboratory assessments, as defined in Appendix 1, must be conducted in 
accordance with the laboratory manual and the Schedule of Activities. 
8.1.7.1. 
Liver Function Tests 
In order to be eligible for this study, patients must have an $/743 U/L for men or 28 U/L 
for women. ALT and AST stability may be evaluated prior to randomization per Section 5.  
During the course of the study, liver function tests (LFTs) will be monitored per the Schedule of 
Activities. Refer to Appendix 1 for a list of tests to be performed, and to Appendix 3 for 
additional information on criteria for increased liver chemistry monitoring. 
8.1.8. 
Transient Elastography and Controlled Attenuation Parameter 
Liver stiffness will be assessed by vibration-controlled transient elastography (via FibroScan®) at 
Screening to determine study eligibility. If results from transient elastography measurement 
within 3 months of Screening are available, these values can be used to assess eligibility and do 
not need to be repeated.  
The transient elastography requirement is intended to select for patients likely to have at least F1 
fibrosis. The protocol excludes patients with cirrhosis based on medical history or clinical signs 
or symptoms (Exclusion criteria #2). Prior studies indicate variability in the ranges of liver 
stiffness measured by transient elastography in NASH patients with fibrosis or cirrhosis. In 
STELLAR-3, which enrolled patients with bridging fibrosis, median liver stiffness at baseline 
was approximately 13 kPa, with an interquartile range between 10 and 17 kPa (Harrison 2020). 
In STELLAR-4, which enrolled patients with cirrhosis, median liver stiffness at baseline was 
approximately 20-21 kPa, with an interquartile range between 14 and 30 kPa (Harrison 2020). 
The utility of transient elastography to diagnose cirrhosis in the setting of NASH also appears 
limited based on the low positive predictive value (PPV) of even relatively high kPa thresholds. 
For a threshold of 21 kPa, the upper limit for this study, the PPV for F4 fibrosis (i.e., cirrhosis) in 
the setting of NASH is 0.37 (which may be even lower in a population with low prevalence of

cirrhosis, such as one in which cirrhosis is excluded on clinical grounds), with a negative 
predictive value of 0.96 (Eddowes 2019). This threshold has a sensitivity of 0.59 and a 
specificity of 0.90 for a diagnosis of cirrhosis in the setting of NASH (Eddowes 2019). 
CAP is an assessment of liver steatosis and is generally used to complement the assessment of 
liver stiffness by transient elastography for evidence of NASH (Eddowes 2019). CAP estimates 
the total ultrasonic attenuation (go-and-return path), expressed in dB/m, based on the postulate 
that fat affects ultrasound propagation. A CAP threshold of 274 dB/m has sensitivity of 0.9 and 
specificity of 0.6 IRULGHQWLILFDWLRQRIOLYHUVWHDWRVLVRI(Eddowes 2019). The threshold of 
280 dB/m was chosen to identify patients who are likely to have elevated liver steatosis, in 
conjunction with the other imaging assessments at screening, including cT1. 
Patients who meet NASH entry criteria based on a liver biopsy (Inclusion Criteria #4) should 
still undergo transient elastography at Screening to enable assessment of change from baseline in 
stiffness by transient elastography. 
Transient elastography will also be conducted at Week 12, and at ET.  
8.1.9. 
Magnetic Resonance Imaging: Correct T1 and Proton Density Fat Fraction  
MRI cT1 will be conducted as specified in the Schedule of Activities.  
MRI cT1 is a novel MRI-based quantitative metric for assessing a composite of liver 
inflammation and fibrosis. This assessment is based on multiparametric MRI data, measuring 
relaxation time that varies based on extracellular tissue fluid attributed to inflammation and 
fibrosis, with a longer relaxation time occurring with more extracellular fluid; the measurement 
is corrected for elevated iron content, which has an opposing effect on relaxation time (Banerjee 
2014). Values for cT1 have been shown to correlate with the NAFLD Activity Score (NAS) and 
its components, as well as with degree of fibrosis by liver histology (Banerjee 2014; Dennis 
2021). A population at low risk for NAFLD was found to have values ranging from 573 to 
852 ms with a median of 666 ms and interquartile range from 643 to 694 ms, with high cT1 
values (e.g. > 875 ms) having been shown to strongly predict liver-related clinical outcomes 
(e.g., hepatic encephalopathy, variceal bleeding, ascites, death) (Mojtahed 2019). In conjunction 
with other screening assessments, a threshold of 800 ms will enrich for a NASH population with 
fibrosis; this threshold has a sensitivity of 86% and a specificity of 93% for identifying patients 
ZLWK)ILEURVLVBanerjee 2014). Stratification for values > 900 ms will ensure a balance 
between higher vs moderate baseline values between treatment groups. 
An MRI cT1 may proceed on the basis of the initial screening ALT and AST values, given all 
other eligibility criteria are met, but randomization should not occur prior to confirmation of 
ALT and AST stability as necessary, per Section 5.

An MRI cT1 should be performed at ET if the patient has had at least 4 weeks of dosing.   
The images will be analyzed by a central reader.  
MRI-PDFF quantifies the relative amount of water vs fat in a tissue bases on signals from proton 
groups that vary depending on tissue cell type (Caussy 2018). PDFF is expressed as a percentage 
(range from 0-100%) representing the ratio of density of mobile protons from triglycerides 
relative to total triglyceride and water mobile proton density (although there are also triglyceride 
elements that are not visible by magnetic resonance and do not contribute to PDFF 
determination). In the liver, PDFF correlates with histological assessment of hepatic steatosis, 
and PDFF has been advanced as a measure of liver fat content to assess treatment response in 
NASH studies (Caussy 2018). PDFF values correlate with NAS score on liver histology, with a 
strong correlation with steatosis (rs = 0.68, p < 0.001) (Dennis 2021). A PDFF threshold of 
generally reflects abnormal steatosis as seen in NAFLD or NASH (Szczepaniak 2005; Tang 
2013). PDFF and cT1 values have been shown to be strongly correlated with each other in 
NASH patients (rs = 0.66, p < 0.001) (Dennis 2021), but it is not yet established how values with 
these modalities may change in response to anti-inflammatory therapies such as TERN-201. 
MRI-PDFF data will be collected along with MRI cT1. 
8.2. 
Pharmacokinetics 
Plasma samples will be collected for measurement of plasma concentrations of study drug and 
metabolites as specified in the Schedule of Activities and Appendix 2. 
Urine samples will be collected for measurement of urine concentrations of study drug and 
metabolites as specified in the Schedule of Activities and Appendix 2.  
Patients in the PK/PD sub-study will undergo intensive and trough PK sample collection as 
specified in the Schedule of Activities and Appendix 2. 
Patients who are not participating in the PK/PD sub-study will undergo trough PK sampling 
only, as specified in the Schedule of Activities and Appendix 2. 
Instructions for the collection and handling of biological samples will be provided by the 
Sponsor. The actual date and time (24-hour clock time) of each sample will be recorded. 
Samples will be used to evaluate the PK of study drug and its metabolites. Samples collected for 
analyses of parent drug and metabolite concentration may also be used to evaluate safety or 
efficacy aspects related to concerns arising during or after the study. 
Parent drug and metabolite concentration information that may unblind the study will not be 
reported to investigative sites or blinded personnel until the study has been unblinded.

8.5. 
Adverse Events and Serious Adverse Events 
An AE is any untoward medical occurrence in a patient or clinical study patient, temporally 
associated with the use of study drug, whether or not considered related to the study drug.  
An SAE is defined as any untoward medical occurrence that, at any dose, results in the 
following: death; is life threatening; requires in-patient hospitalization; results in persistent 
disability or incapacity; is a congenital anomaly or birth defect; or is a medically important event 
or reaction that may not be immediately life-threatening or result in death or hospitalization but 
may jeopardize the patient or may require medical or surgical intervention to prevent one of the 
other outcomes in the definition.  
Events meeting the definition of an AE or SAE are defined in Appendix 6, including details on 
recording, reporting, and follow-up of AEs and SAEs, assessment of severity, and assessment of 
causality. AEs will be reported by the patient (or, when appropriate, by a caregiver, surrogate, or 
the patient's legally authorized representative) at every study visit. 
The Investigator and any qualified designees are responsible for detecting, documenting, and 
recording events that meet the definition of an AE or SAE and remain responsible for following 
up AEs that are serious, considered related to the study drug or study procedures, or that caused 
the patient to discontinue the study drug (see Section 7). 
8.5.1. 
Time Period and Frequency for Collecting AE and SAE Information 
After informed consent but prior to initiation of study drug, the following types of events should 
be reported: all AEs and SAEs related to protocol-mandated procedures.  
Medical occurrences (events considered not related to protocol-mandated procedures) that begin 
before the start of study drug but after obtaining informed consent will be recorded on the 
Medical History/Current Medical Conditions section of the eCRF, not the AE section. 
All AEs and SAEs, regardless of cause or relationship, will be collected from the start of study 
drug through the Follow-Up Period, at every study visit, as specified in the Schedule of 
Activities (Section 1.3).

All SAEs will be recorded and reported to the Sponsor or designee immediately and under no 
circumstance should this exceed 24 hours, as indicated in Appendix 6. The Investigator will 
submit any updated SAE data to the Sponsor within 24 hours of it being available. 
Investigators are not obligated to actively seek reports of AEs or SAEs after conclusion of the 
study participation. However, if the Investigator learns of any SAE, including a death, at any 
time after a patient has been discharged from the study, and he/she considers the event to be 
reasonably related to the study drug or study participation, the Investigator must promptly notify 
the Sponsor. 
8.5.2. 
Method of Detecting AEs and SAEs 
The method of recording, evaluating, and assessing causality of AEs and SAEs and the 
procedures for completing and transmitting SAE reports are provided in Appendix 6. 
Care will be taken not to introduce bias when detecting AEs and/or SAEs. Open-ended and 
non-leading verbal questioning of the patient is the preferred method to inquire about 
AE occurrences. 
8.5.3. 
Follow-up of AEs and SAEs 
After the initial AE and/or SAE report, the Investigator is required to proactively follow each 
patient at subsequent visits/contacts. All SAEs will be followed until resolution, stabilization, the 
event is otherwise explained, or the patient is lost to follow-up (as defined in Section 7.3). 
Further information on follow-up procedures is provided in Appendix 6. 
8.5.4. 
Regulatory Reporting Requirements for SAEs 
Prompt notification by the Investigator to the Sponsor of a SAE is essential so that legal 
obligations and ethical responsibilities towards the safety of patients and the safety of a study 
drug under clinical investigation can be met. 
The Sponsor has a legal responsibility to notify both the local regulatory authority and other 
regulatory agencies about the safety of a study drug under clinical investigation. The Sponsor 
will comply with country-specific regulatory requirements relating to safety reporting to the 
regulatory authority, IRB/IEC, and Investigators. 
Investigator safety reports must be prepared for SUSARs according to local regulatory 
requirements and sponsor policy and forwarded to Investigators as necessary. 
An Investigator who receives an investigator safety report describing a SAE or other specific 
safety information (e.g., summary or listing of SAEs) from the sponsor will review and then file

it along with the Investigator’s Brochure and will notify the IRB/IEC, if appropriate according to 
local requirements. 
8.5.5. 
Pregnancy 
Details of all pregnancies in female patients and female partners of male patients will be 
collected after the start of study drug until 30 days following the last dose of the study drug. 
If a pregnancy is reported, the Investigator should inform the Sponsor within 24 hours of 
learning of the pregnancy and should follow the procedures outlined in Appendix 6 and 
Appendix 7. 
Abnormal pregnancy outcomes (e.g., spontaneous abortion, fetal death, stillbirth, congenital 
anomalies, ectopic pregnancy) are considered SAEs. 
8.6. 
Treatment of Overdose 
Overdose with this product has not been reported. Neither the effect of overdose nor antidote are 
known. The maximum amount of TERN-201 that can be safely administered in a single dose has 
not been determined. The highest single dose of TERN-201 capsules in clinical studies was 
10 mg. Patients who receive higher than the protocol-defined dose should be carefully monitored 
for adverse events, and the quantity of the excess dose and duration of excess dose should be 
documented in the eCRF; the Medical Monitor should be notified immediately. Refer to 
Appendix 6 for additional information on AE reporting.  
In an instance in which a patient receives higher than the protocol-defined dose, decisions 
regarding any future dosing of study drug will be made by the Investigator in consultation with 
the Sponsor based on the clinical evaluation of the patient.

Statistical Considerations 
9.1. 
Statistical Hypotheses 
The primary objective of the study is to evaluate the safety and tolerability of orally administered 
TERN-201. No statistical hypothesis testing will be applied. 
9.2. 
Sample Size Determination 
The sample size is based on clinical feasibility and adequate size to characterize safety in the 
study population, without consideration for statistical power.   
Patients who are randomized but do not receive study drug for any reason may be replaced. 
Patients who discontinue treatment early for reasons other than safety (e.g., withdrawal of 
consent, lost to follow-up, patient relocated) may also be replaced. Replacement patients will 
receive the same treatment assignment as the patient that discontinued treatment early.   
9.3. 
Analysis Sets 
The following analysis sets are defined: 
Analysis Sets 
Description 
Randomized 
All patients who are randomized into any one of the 
treatment groups 
PK 
All randomized patients who received at least 1 dose of 
TERN-201 and have evaluable PK data 
PD 
All randomized patients who received at least 1 dose of study 
drug (TERN-201 or placebo) and have evaluable PD data 
Safety 
All patients who received at least 1 dose of study drug. 
Patients will be analyzed according to the intervention they 
actually received. 
Efficacy Analysis Set  
All randomized patients who received at least 1 dose of study 
drug. Patients will be analyzed according to the intervention 
they are planned to receive. 
Per Protocol Analysis Set (PP)  All randomized patients who have completed the study 
without any major protocol deviations. The major protocol 
deviations will be defined in the Statistical Analysis Plan 
(SAP) and finalized prior to database lock (DBL). A separate 
completer analysis set may also be defined in the SAP.

A patient is considered to have completed the study if he/she has completed all phases of the 
study including the last scheduled assessment in the Follow-Up Period. 
9.4. 
Statistical Analyses 
This section presents a summary of the planned statistical analyses. The SAP will provide the 
details and will be finalized prior to clinical database lock. 
9.4.1. General Considerations 
For continuous data, summary statistics will include the arithmetic mean, arithmetic standard 
deviation, median, minimum, maximum, and number of patients with non-missing assessments. 
For log-normal data (e.g., the PK parameters: AUCs and maximum observed concentration 
[Cmax]), the geometric mean and coefficient of variation (CV%) will also be presented. For 
categorical data, frequency counts and percentages will be presented.   
9.4.2. 
Primary Endpoint(s) 
The primary safety parameters will include TEAEs and treatment emergent clinical safety 
laboratory parameters.  
Reported AEs will be coded using the latest version of Medical Dictionary for Regulatory 
Activities (MedDRA) and graded for severity according to NCI CTCAE, Version 5.0.  
All TEAEs will be listed and incidence summarized by MedDRA Preferred Term and System 
Organ Class, as well as by maximum severity and study drug causality. Summaries of treatment 
emergent SAEs, TEAEs related to study drug, TEAEs resulting in study drug discontinuations, 
and deaths will also be produced. 
Changes and percent changes from baseline of quantitative measurements will be summarized by 
treatment group and timepoints. Laboratory abnormalities will be graded according to NCI 
CTCAE Version 5.0, where applicable. Shifts in CTCAE grade from baseline will be 
summarized by treatment group.  
Further details on the analysis of additional safety parameters will be provided in the SAP. 
9.4.3. 
Secondary Endpoints 
9.4.3.1. 
Pharmacokinetic Endpoints 
Noncompartmental PK analysis will be performed on individual plasma and urine concentration 
data.

Individual plasma concentrations of TERN-201 and its metabolites, if applicable, will be listed 
by timepoint and summarized by treatment group. Individual and mean concentration-time 
profiles will be presented graphically in linear and semi-log scales.  
PK parameters of TERN-201 and its metabolites (exploratory endpoint) will be listed 
individually and summarized with descriptive statistics, including arithmetic and geometric 
mean, median, standard deviation, arithmetic and geometric CV%, minimum and maximum. The 
Cmax and AUC will be plotted. 
9.4.3.2. 
Change from Baseline in Plasma VAP-1/SSAO Activity 
A secondary efficacy endpoint is change from baseline in plasma VAP-1/SSAO activity with 12 
weeks of treatment in patients treated with either TERN-201 or matching placebo. The change 
and percent change from baseline in plasma VAP-1/SSAO amine oxidase activity in each 
TERN-201 group will be compared with placebo separately at each post baseline visit, without 
controlling for any family-wise error rate (overall type I error), using MMRM (mixed model 
repeated measures) model with treatment group, visit, and treatment group by visit interaction as 
factors and baseline value as covariate. 
Change and percent change from baseline plasma VAP-1/SSAO amine oxidase activity will be 
listed and summarized with descriptive statistics including arithmetic and geometric mean, 
median, standard deviation, arithmetic and geometric CV, minimum, and maximum. Exposure-
response and dose-response relationships of orally administered TERN-201 will also be assessed 
as applicable (exploratory endpoints). 
Exposure-response and dose-response analysis may be produced if Part 2 of the study is enrolled, 
as applicable. The change and percent change from baseline in plasma VAP-1/SSAO activity 
will be compared between the different TERN-201 dose groups and placebo using an analysis of 
covariance (ANCOVA) model with the treatment group as a factor and baseline values as a 
covariate. Corresponding least square mean treatment differences with 2 sided 95% confidence 
limits will be computed for each pairwise comparison.  
Further details on the analysis models will be provided in the SAP. 
9.4.4. 
Exploratory Endpoints 
Descriptive statistics for the values, change from baseline, and percent change from baseline will 
be summarized by treatment group over time.

The following exploratory endpoints will be analyzed at each visit using an MMRM model 
similar to the model described in Section 9.4.3.1. Exposure-response and dose-response analysis 
may be produced if Part 2 of the study is enrolled, as applicable.  
x Change from baseline in cT1 by MRI 
x Change from baseline in liver fat content by MRI-PDFF 
x Change from baseline in stiffness by transient elastography  
x Change from baseline in ALT  
x Change from baseline in GGT  
x Change from baseline in AST 
x Change from baseline in NASH and fibrosis biomarkers 
x Change from baseline in inflammatory biomarkers 
x Change from baseline in eGFR, urine protein, UPCR, and UACR  
x Change from baseline in plasma methylamine levels (PD marker of VAP-1/SSAO 
inhibition) 
9.4.4.1. 
PD Endpoints 
In addition to analyses described above, pharmacodynamic parameters (plasma VAP-1/SSAO 
activity and plasma methylamine levels) will be listed, summarized, and described by plotting 
the concentration-time curve or time-effect curve. The correlation of PK and PD parameters will 
also be explored.  
9.5. 
Interim Analysis 
An interim analysis will be performed after all patients in Part 1 have completed Week 6 
assessments. Interim PD data will be assessed as described in Section 9.4.4.1. If robust VAP-
1/SSAO activity suppression is observed and available PK suggests that a lower dose may also 
possibly lead to robust VAP-1/SSAO activity suppression, enrollment in Part 2 with 4 mg 
TERN-201 may be initiated. Additionally, if safety data indicates 10 mg TERN-201 is overall 
safe and well-tolerated and anticipated exposures with a higher dose remain below the exposure 
limit (see Section 4.3), enrollment in Part 2 to assess a dose up to 20 mg TERN-201 in Part 2 
may be initiated.

10.1.8. 
Study and Site Start and Closure 
The first patient screened is considered the first act of recruitment and will be the study start 
date. 
The sponsor or designee reserves the right to close the study site or terminate the study at any 
time for any reason at the sole discretion of the sponsor. Study sites will be closed upon study 
completion. A study site is considered closed when all required documents and study supplies 
have been collected and a study-site closure visit has been performed. 
The Investigator may initiate study-site closure at any time, provided there is reasonable cause 
and sufficient notice is given in advance of the intended termination. 
Reasons for the early closure of a study site by the sponsor or Investigator may include but are 
not limited to: 
x 
Failure of the Investigator to comply with the protocol, the requirements of the IRB/IEC 
or local health authorities, the sponsor's procedures, or GCP guidelines 
x 
Inadequate recruitment of patients by the Investigator 
x 
Discontinuation of further study drug development

Appendix 1: Clinical Laboratory Tests 
The tests detailed in Table 2 will be performed by the central laboratory. Local laboratory testing 
should only be used in the event that central laboratory results would not available in time for 
necessary clinical decision making. If a local sample is required, it is important that a sample for 
central analysis is obtained at the same time. Additionally, if the local laboratory results are used 
to make either a study drug decision or response evaluation, the results must be entered into the 
eCRF. 
Protocol-specific requirements for inclusion or exclusion of patients are detailed in Section 5. 
Additional tests may be performed at any time during the study as determined necessary by the

Table 4 
Liver Chemistry Increased Monitoring Criterion and Follow-Up 
Criterion 
Actions 
Elevated ALT and/or AST above 2 × 
Baseline or above 5 × ULN for < 1 
week 
x Patient can continue study drug at the discretion 
of the Investigator 
x Repeat measurement of LFTs (including ALT, 
AST, ALP, and total bilirubin) will be performed 
within 48-72 hours to confirm the abnormalities 
and to determine if they are increasing or 
decreasing. If total bilirubin is increased there 
should be a reflex to direct and indirect bilirubin.  
x PT/INR and albumin will be tested when 
significantly abnormal liver function is observed, 
and repeated with repeat measurement of LFTs. 
x Upon confirmation of elevated LFTs, close 
observation by repeating LFTs every 24 to 72 
hours will be initiated immediately.  
x Frequency of monitoring can be decreased as 
LFTs decrease at the Investigator’s discretion.  
x The Investigator will collect detailed history 
information on concomitant symptoms, new 
medications, drug or alcohol exposure, etc., to 
identify possible cause of abnormal LFTs.  
x Close observation on abnormal LFTs will last 
until the parameters return to baseline, or to a 
stable level judged by the Investigator.   
Note: If one of the following situations occurs and is considered related to the study drug without 
alternative etiology, study drug may be discontinued at the discretion of the Investigator and the 
Medical Monitor should be informed (with repeat test performed within 48-72 hours once initial 
abnormality is detected):  
x 
ALT or AST > 8 × ULN  
x 
ALT or AST > 5 × ULN for more than 1 week  
x 
ALT or AST > 2× Baseline with the appearance of fatigue, nausea, vomiting, right upper quadrant 
pain or tenderness, fever, rash, and/or eosinophilia (> 5%) 
x 
ALT or AST > 2 × Baseline and total bilirubin > 2 × ULN or INR >1.5 for more than 1 week, 
confirmed with a repeat assessment

Appendix 6: Adverse Events: Definitions and Procedures for Recording, 
Evaluating, Follow-up, and Reporting 
AE Definition 
x An AE is any untoward medical occurrence in a patient or clinical study patient, 
temporally associated with the use of study drug, whether or not considered related to 
the study drug. 
x NOTE: An AE can therefore be any unfavorable and unintended sign (including an 
abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally 
associated with the use of study drug. 
 
Events Meeting the AE Definition 
x Any safety assessment (e.g., ECG, radiological scans, vital signs measurements), 
including those that worsen from baseline, considered clinically significant in the 
medical and scientific judgment of the Investigator (i.e., not related to progression of 
underlying disease). 
x A clinical condition or symptom associated with an abnormal laboratory test result 
(e.g., hematology, clinical chemistry, or urinalysis). An abnormal laboratory test that is 
not accompanied with other signs or symptoms should not be reported as an AE.  
x Exacerbation of a chronic or intermittent pre-existing condition including either an 
increase in frequency and/or severity of the condition. 
x New conditions detected or diagnosed after study drug administration even though it 
may have been present before the start of the study. 
x Signs, symptoms, or the clinical sequelae of a suspected drug-drug interaction. 
x Signs, symptoms, or the clinical sequelae of a suspected overdose of either study drug 
or a concomitant medication. Overdose per se will not be reported as an AE/SAE 
unless it is an intentional overdose taken with possible suicidal/self-harming intent. 
Such overdoses should be reported regardless of sequelae.

Terns, Inc.  
Version: Amendment 3 
Version Date: 17 August 2021 
 
 
CONFIDENTIAL 
Page 76 of 92 
 
Events NOT Meeting the AE Definition 
x Abnormal laboratory findings or other abnormal safety assessments that are associated 
with an underlying disease present at baseline without worsening, unless judged by the 
Investigator to be more severe than expected for the patient’s condition. 
x An abnormal laboratory test that is not accompanied with other signs or symptoms. 
x The disease/disorder being studied or signs, or symptoms of the disease/disorder being 
studied, unless more severe than expected for the patient’s condition. 
x Medical or surgical procedure (e.g., endoscopy, appendectomy): the condition that 
leads to the procedure is the AE. 
x Situations in which an untoward medical occurrence did not occur (social and/or 
convenience admission to a hospital). 
x Anticipated day-to-day fluctuations of pre-existing disease(s) or condition(s) present or 
detected at the start of the study that do not worsen. 
Definition of SAE 
An SAE is an AE that meets the following criteria: 
An SAE is defined as any untoward medical occurrence that, at any dose: 
a. Results in death 
b. Is life-threatening 
The term 'life-threatening' in the definition of 'serious' refers to an event in which the patient 
was at risk of death at the time of the event. It does not refer to an event, which hypothetically 
might have caused death, if it were more severe. 
c. 
Requires inpatient hospitalization or prolongation of existing hospitalization 
x In general, hospitalization signifies that the patient has been detained (usually 
involving at least an overnight stay) at the hospital or emergency ward for observation 
and/or treatment that would not have been appropriate in the physician’s office or 
outpatient setting. Complications that occur during hospitalization are AEs. If a 
complication prolongs hospitalization or fulfills any other serious criteria, the event is 
serious. When in doubt as to whether “hospitalization” occurred or was necessary, the 
AE should be considered serious. 
x Hospitalization for elective treatment of a pre-existing condition that did not worsen 
from baseline is not considered an AE. 
d. Results in persistent disability/incapacity 


Protocol TERN201-1007 
Terns, Inc.  
Version: Amendment 3 
Version Date: 17 August 2021 
 
 
CONFIDENTIAL 
Page 77 of 92 
 
x The term disability means a substantial disruption of a person’s ability to conduct 
normal life functions. 
x This definition is not intended to include experiences of relatively minor medical 
significance such as uncomplicated headache, nausea, vomiting, diarrhea, influenza, 
and accidental trauma (e.g., sprained ankle) which may interfere with or prevent 
everyday life functions but do not constitute a substantial disruption. 
e. 
Is a congenital anomaly/birth defect 
f. 
Other situations: 
x Medical or scientific judgment should be exercised in deciding whether SAE reporting 
is appropriate in other situations such as important medical events that may not be 
immediately life-threatening or result in death or hospitalization but may jeopardize the 
patient or may require medical or surgical intervention to prevent one of the other 
outcomes listed in the above definition. These events should usually be considered 
serious. 
x 
Examples of such events include invasive or malignant cancers, intensive treatment in 
an emergency room or at home for allergic bronchospasm, blood dyscrasias or 
convulsions that do not result in hospitalization, or development of drug dependency or 
drug abuse. 
If an event does not meet the AE definition, then it cannot be an SAE even if serious conditions 
are met (e.g., hospitalization for signs/symptoms of the disease under study, death due to 
progression of disease). 
Recording and Follow-Up of an AE and/or SAE 
AE and SAE Recording 
x When an AE and/or SAE occurs, it is the responsibility of the Investigator to review all 
documentation (e.g., hospital progress notes, laboratory reports, and diagnostics 
reports) related to the event. 
x The Investigator will then record all relevant AE and/or SAE information in the eCRF. 
x It is not acceptable for the Investigator to send photocopies of the patient’s medical 
records to the Sponsor or designee in lieu of completion of the AE or SAE eCRF. 
x There may be instances when copies of medical records for certain cases are requested 
by the Sponsor or designee. In this case, all patient identifiers, with the exception of 
the patient number, will be redacted on the copies of the medical records before 
submission to the Sponsor or designee.

x The Investigator will attempt to establish a diagnosis of the event based on signs, 
symptoms, and/or other clinical information. Whenever possible, the diagnosis (not the 
individual signs/symptoms) will be documented as the AE and/or SAE. 
Assessment of Severity  
The Investigator will be asked to provide an assessment of the severity of the AE using NCI 
CTCAE v5.0 categories as follows:  
x Grade 1: Mild; asymptomatic or mild symptoms; clinical or diagnostic observations 
only; intervention not indicated.  
x Grade 2: Moderate; minimal, local, or noninvasive intervention indicated; limiting age 
appropriate instrumental ADL.  
x Grade 3: Severe or medically significant but not immediately life-threatening; 
hospitalization or prolongation of hospitalization indicated; disabling; limiting self-
care ADL.  
x Grade 4: Life-threatening consequences; urgent intervention indicated.  
x Grade 5: Death related to AE. 
For detailed organ system AE severity grading, please refer to NCI CTCAE v5.0:  
https://ctep.cancer.gov/protocoldevelopment/electronic_applications/docs/CTCAE_v5_Quick_Reference_8.5x11.pdf 
 
Assessment of Causality 
x The Investigator is obligated to assess the relationship between study drug and each 
occurrence of each AE and/or SAE. 
x The Investigator (or designee) will make a determination of the relationship of the AE 
to the study drug using a 4-category system according to the following guidelines:  
o Not Related: The AE is definitely caused by the subject’s clinical state or the 
study procedure/conditions.  
o Unlikely Related: The temporal association between the AE and the drug is 
such that the drug is not likely to have any reasonable association with the AE.  
o Possibly Related: The AE follows a reasonable temporal sequence from the 
time of drug administration but could have been produced by the subject’s 
clinical state or the study procedures/conditions.  
o Related: The AE follows a reasonable temporal sequence from administration 
of the drug, abates upon discontinuation of the drug, follows a known or 
hypothesized cause effect relationship, and (if appropriate) reappears when the 
drug is reintroduced. 
x For each AE and/or SAE, the Investigator must document in the medical notes that 
he/she has reviewed the AE and/or SAE and has provided an assessment of causality. 
x There may be situations in which an SAE has occurred and the Investigator has 
minimal information to include in the initial report to the Sponsor or designee. 
However, it is very important that the Investigator always make an assessment of

causality for every event before the initial transmission of the SAE data to the Sponsor 
or designee. 
x The Investigator may change his/her opinion of causality in light of follow-up 
information and send a SAE follow-up report with the updated causality assessment. 
x The causality assessment is one of the criteria used when determining regulatory 
reporting requirements. 
Follow-up of AEs and SAEs 
x The Investigator is obligated to perform or arrange for the conduct of supplemental 
measurements and/or evaluations as medically indicated or as requested by the 
Sponsor or designee to elucidate the nature and/or causality of the AE or SAE as fully 
as possible. This may include additional laboratory tests or investigations, 
histopathological examinations, or consultation with other health care professionals. 
x If a patient dies during participation in the study or during a recognized follow-up 
period, the Investigator will provide the Sponsor or designee with a copy of any 
post-mortem findings including histopathology.  
x New or updated information will be recorded in the originally completed CRF. 
x The Investigator will submit any updated SAE data to the Sponsor or designee within 
24 hours of receipt of the information. 
Reporting of SAEs 
SAE Reporting to Sponsor or designee via Paper CRF 
x Email transmission of the SAE paper Report Form is the preferred method to transmit 
this information to the CATO Safety Group (Terns-PhV@cato-sms.com). 
x Notification by facsimile transmission to the CATO Safety Group is also acceptable 
(919-361-2536) 
x Initial notification via telephone or email does not replace the need for the Investigator 
to complete, sign, and return the SAE report form within the designated reporting time 
frames. 
x Contacts and additional instructions for SAE reporting can be found in in the Study 
Procedures Manual provided.

Appendix 7: Contraceptive Guidance and Collection of Pregnancy 
Information 
Definitions: 
Woman of Childbearing Potential (WOCBP) 
A woman is considered fertile following menarche and until becoming post-menopausal unless 
permanently sterile (see below).  
Women in the following categories are not considered WOCBP 
1. Premenopausal female with surgical sterility defined as 1 of the following: 
x Documented hysterectomy 
x Documented bilateral salpingectomy 
x Documented bilateral oophorectomy 
 
2. Postmenopausal female 
x A postmenopausal state is defined as no menses for 12 months without an alternative 
medical cause. 
o A high follicle stimulating hormone (FSH) level in the postmenopausal range should 
be used to confirm a postmenopausal state in women not using hormonal 
contraception or hormonal replacement therapy (HRT).  
x Females on HRT and whose menopausal status is in doubt will be required to follow the 
protocol-mandated contraception guidance if they wish to continue their HRT during the 
study. Otherwise, they must discontinue HRT to allow confirmation of postmenopausal 
status before study enrollment. 
For individuals with permanent infertility due to an alternate medical cause not listed above, 
(e.g., mullerian agenesis, androgen insensitivity), Investigator discretion should be applied to 
determining study entry.  
Note: Documentation can come from the site personnel’s: review of the patient’s medical 
records, medical examination, or medical history interview. 
Contraception Guidance: 
Male patients who are sexually active with a female partner of childbearing potential must be 
either surgically sterile (confirmed by documented azoospermia > 90 days after the procedure) or 
follow the guidance per Table 5, during the study and until 30 days following the last dose of 
study drug. Male patients must not donate sperm from the first dose of study drug until 30 days 
following the last dose of the study drug.

Female patients of childbearing potential must have negative serum pregnancy test at screening 
and randomization, not be breastfeeding, and not plan to become pregnant during study or within 
30 days after dosing of study drug. Female patients of childbearing potential must either be 
surgically sterile (documented hysterectomy, bilateral salpingectomy, bilateral oophorectomy) or 
follow the guidance per Table 5, during the study and until 30 days following the last dose of the 
study drug.

Contraceptive Methods  
CONTRACEPTIVE METHODS ALLOWED DURING THE STUDY INCLUDE:  
A. Highly Effective Methods That Have Low User Dependency and May be Used Alone  
Failure rate of <1% per year when used consistently and correctly. 
x Documented bilateral tubal occlusion  
x Vasectomized partner 
Vasectomized partner is a highly effective contraceptive method provided that the partner is the sole sexual 
partner of the woman of childbearing potential and the absence of sperm has been confirmed. If not, an 
additional highly effective method of contraception should be used. Spermatogenesis cycle is approximately 
90 days.

Male condom with or without spermicide (single barrier).  
D. Double Barrier Methods That May be Used Alone 
A combination of male condom with either cervical cap, diaphragm, or sponge with spermicide (double-barrier).  
E. SEXUAL ABSTINENCE 
Sexual abstinence is considered a highly effective method only if defined as refraining from heterosexual 
intercourse during the entire period of risk associated with the study intervention. The reliability of sexual 
abstinence needs to be evaluated in relation to the duration of the study and the preferred and usual lifestyle of the 
patient.  
UNACCEPTABLE CONTRACEPTIVE METHODS 
Periodic abstinence (calendar, symptothermal, post-ovulation methods), withdrawal (coitus interruptus), 
spermicides only, and lactational amenorrhoea method (LAM) are not acceptable methods of contraception. 
Collection of Pregnancy Information:  
Male Patients with Partners Who Become Pregnant 
The Investigator will attempt to collect pregnancy information on any male patient’s female 
partner who becomes pregnant while the male patient is in this study, or if they become pregnant

within 30 days following the last dose of the study drug. This applies only to male patients who 
receive study drug. 
After obtaining the necessary signed informed consent from the pregnant female partner directly, 
the Investigator will record pregnancy information on the appropriate form and submit it to the 
sponsor within 24 hours of learning of the partner’s pregnancy. The female partner will also be 
followed to determine the outcome of the pregnancy. Information on the status of the mother and 
child will be forwarded to the sponsor. Generally, the follow-up will be no longer than 6 to 8 
weeks following the estimated delivery date. Any termination of the pregnancy will be reported 
regardless of fetal status (presence or absence of anomalies) or indication for the procedure.  
Female Patients Who Become Pregnant 
Any female patient who becomes pregnant while participating in the study will discontinue study 
drug.  
The Investigator will collect pregnancy information on any female patient who becomes 
pregnant while participating in this study, or if they become pregnant 30 days following the last 
dose of study drug. The initial information will be recorded on the appropriate form and 
submitted to the sponsor within 24 hours of learning of a patient's pregnancy.  
The patient will be followed to determine the outcome of the pregnancy. The Investigator will 
collect follow-up information on the patient and the neonate and the information will be 
forwarded to the sponsor. Generally, follow-up will not be required for longer than 6 to 8 weeks 
beyond the estimated delivery date. Any termination of pregnancy will be reported, regardless of 
fetal status (presence or absence of anomalies) or indication for the procedure. 
While pregnancy itself is not considered to be an AE or SAE, any pregnancy complication or 
elective termination of a pregnancy for medical reasons will be reported as an AE or SAE.  
A spontaneous abortion (occurring at < 22 weeks gestational age) or still birth (occurring at > 
22 weeks gestational age) is always considered to be an SAE and will be reported as such.  
Any post-study pregnancy related SAE considered reasonably related to the study drug by the 
Investigator will be reported to the sponsor as described in Section 8.5.5. While the Investigator 
is not obligated to actively seek this information in former study patients, he or she may learn of 
an SAE through spontaneous reporting.

Appendix 8: COVID-19 Assessments 
At Screening:  
x SARS-CoV-2 testing to assess for active infection (e.g., molecular test such as 
polymerase chain reaction [PCR] or viral antigen serology) and past infection 
(Immunoglobulin G [IgG] and Immunoglobulin M [IgM] antibodies)  
x Testing at Screening may be omitted for patients who have completed a COVID-19 
vaccination series, with adequate documentation, at the Investigator’s discretion  
At Week 0, 6, and 12:  
x Testing for past infection via antibody testing (IgG and IgM) if prior IgG was negative  
x If Week 0 occurs within 2 weeks of Screening, site may omit repeat SARS-CoV-2 testing 
at Investigator’s discretion 
x If IgM antibody test is positive, may reflex to test for SARS-CoV-2 active infection at 
Investigator’s discretion 
x Testing at these timepoints may be omitted for patients who have completed a COVID-19 
vaccination series, with adequate documentation, at the Investigator’s discretion  
Ad-hoc:  
x In the event of symptoms suggestive of COVID-19, ad hoc testing (including molecular 
test such as PCR or viral antigen serology, and/or antibody testing), may be completed at 
Investigator’s discretion 
Sites may use local laboratory testing for COVID-19 assessments instead of central laboratory, 
per site preference. If a local laboratory is used, the results must be entered into the eCRF. 
Results from previous testing may be used if completed within 2 weeks of a scheduled Screening 
or on-study visit. 
Any positive tests reflecting active or recent infection (e.g., molecular test such as PCR or viral 
antigen serology, or IgM antibody) require management per local public health guidelines, at the 
direction of the Investigator.  
If technological changes result in changes to the assays implemented to assess for SARS-CoV-2, 
available central lab assays and testing mechanisms may change. 
The testing approach and schedule may be modified based on the evolving landscape of the 
pandemic or in response to local public health requirements. In that event, regulatory 
requirements, IRB requirements, and local institutional guidelines will be followed, as necessary.

INTRODUCTION 
This statistical analysis plan (SAP) document outlines the statistical methods to be implemented 
during the analyses of Study Protocol TERN201-1007.  The purpose of this plan is to provide 
specific guidelines from which the analyses will proceed.  Any deviations from these guidelines 
will be documented in the clinical study report (CSR).    
This SAP supersedes the statistical considerations identified in the protocol; where 
considerations are substantially different, they are identified in Section 11. Any post-hoc or 
unplanned analyses, or significant changes from the planned analysis in this SAP performed to 
provide results for inclusion in the clinical study report (CSR) but not included in this SAP, will 
be clearly identified in the CSR. Changes to planned analyses do not require an updated SAP but 
should be included in the CSR if significant.

Study Design 
The study is a multi-center, randomized, double-blind, placebo-controlled, adaptive study. 
Up to approximately 80 clinically or histologically diagnosed adult non-cirrhotic presumed 
NASH patients who meet study eligibility criteria will be enrolled and randomized at an overall 
ratio of 2:1 in up to 3 dose groups and placebo across 2 parts of the study. 
Part 1  
In Part 1, approximately 30 patients will receive 10 mg TERN-201 (n = 20) or matching placebo 
(n = 10) orally once daily, for 12 weeks. Part 2 may be enrolled based on an interim analysis, as 
follows: 
In Part 1 of the study, approximately 12 randomized patients will take part in an intensive PK 
and PD collection after the first dose (Week 0/Day 1), at Week 6, and after the last dose of study 
drug (Week 12). Randomization will ensure approximately 8 patients in the TERN-201 group 
and approximately 4 patients in the placebo group are assigned to the PK/PD sub-study. Patients 
who are not participating in the PK/PD sub-study will have trough PK/PD sampling only. 
Part 2  
In Part 2, if initiated, up to approximately 50 patients will receive 4 mg TERN-201 (n = 20), 
and/or up to 20 mg TERN-201 (n = 20), or matching placebo (n = 10) orally once daily, for 12 
weeks. 
In Part 2 of the study, approximately 15 randomized patients will take part in an intensive PK 
and PD collection after the first dose (Week 0/Day 1), at Week 6, and after the last dose of study 
drug (Week 12). Randomization will ensure approximately 6 patients at each TERN-201 dose 
level and approximately 3 patients in the placebo group are assigned to the PK/PD sub-study. 
Patients who are not participating in the PK/PD sub-study will have trough PK/PD sampling 
only. 
The total duration of study participation will be approximately 22 weeks, consisting of a 6-week 
Screening Period, a 12-week Treatment Period and a 4-week Follow-up Period.

SAMPLE SIZE JUSTIFICATION 
The sample size is based on clinical feasibility and adequate size to characterize safety in the 
study population, without consideration for statistical power.   
Patients who are randomized but do not receive study drug for any reason may be replaced. 
Patients who discontinue treatment early for reasons other than safety (e.g. withdrawal of 
consent, lost to follow-up, patient relocated) may also be replaced.

GENERAL STATISTICAL METHODS 
4.1.
Reporting Conventions
Individual patient data obtained from electronic case report forms (eCRFs), central laboratories, 
external sources, and any derived data will be presented in data listings by patient. The primary 
data source will be used for all analyses. All data listings that contain an evaluation date will 
contain a relative study day. Pre-treatment and on-treatment study days are numbered relative to 
the day of the first dose of study drug which is designated as Day 1. The preceding day is Day -1, 
the day before that is Day -2, etc. 
All outputs will be incorporated into Microsoft Word rich text format (.rtf) files, sorted and 
labeled according to the International Council for Harmonisation (ICH) E3 guideline, E3 
Structure and Content of Clinical Study Reports, and formatted to the appropriate page size(s), 
font type, and font size according to Food and Drug Administration (FDA) guidance of Portable 
Document Format Specifications.
For categorical variables, summary tabulations of the number and percentage of patients within 
each category of the parameter will be presented. Percentage calculations will be based on non-
missing data, unless otherwise specified. If there are missing values, the number missing will be 
presented, but without a percentage. Percentages are rounded to 1 decimal place, unless 
otherwise specified.  
For frequency counts of categorical variables, categories whose counts are zero will be displayed 
for the sake of completeness. For example, if none of the patients discontinue due to “Lost to 
Follow-up,” this reason will be included in the table with a count of 0.  Percentages will be

and 100, which will be presented without decimal places. Values less than 0.1% will be 
presented as “<0.1%.” Values less than 100% but greater than 99.9% will be presented as 
“>99.9%.”   
For continuous variables, the number of patients, mean, standard deviation (SD), median, 25th
(Q1) and 75th (Q3) percentiles, minimum, and maximum values will be presented. The precision 
of summary statistics, unless otherwise specified will be as follows:  mean, median, Q1, and Q3 
to 1 more decimal place than the raw data, SD to 2 decimal places more than the raw data, and 
minimum and maximum to the same decimal places as the raw data. In general, the number of 
decimal places should not exceed 3 decimal places unless appropriate. 
For log-normal data (e.g., the PK parameters of area under the concentration-time curve [AUC]
and maximum observed concentration [Cmax]), the geometric mean and geometric coefficient of 
variation (CV%) will also be presented. The precision of descriptive statistics will be as follows:  
mean, median, Q1, and Q3 to 1 more decimal place than the raw data, SD to 2 decimal places 
more than the raw data, the minimum and maximum to the same number of decimal places as the 
raw data, geometric mean to 3 significant figures, and geometric CV% to 1 decimal place. The 
PK parameters Tmax, Tmin, Tlast, and t1/2 will be presented to 1 decimal place and all other plasma 
and urine PK parameters will be presented to 3 significant figures. 
Confidence intervals (CIs) will be provided and will be rounded to 1 decimal place, unless 
otherwise specified, in the table and listing shell. A full set of summary statistics will only be 
presented if 3 or more values are available. If there are less than 3 values, only the min, max, and 
N will be presented. The other summary statistics will be denoted as not calculated (NC). 
For tables where rounding is required, rounding will be done to the nearest round-off unit. For 
down to 97).
All statistical tests comparing groups will be conducted at the 2-sided, 0.05 level of significance, 
unless otherwise specified. Summary statistics for each treatment group will be presented, as 
well as two-sided 90% and 95% CIs comparing groups will be provided. 
Other general programming specifications are provided in Appendix 1. 
4.2. 
Computing Environments 
All descriptive statistical analyses will be performed using SAS software Version 9.4 or higher, 
unless otherwise noted.  
Plasma PK and PD parameters for TERN-201 will be estimated using non-compartmental 
methods with Phoenix WinNonlin® Version 8.3 or higher.
Medical history and AEs will be coded using Medical Dictionary for Regulatory Activities 
(MedDRA) version 24.0. Concomitant medications will be coded using World Health 
Organization Drug Dictionary (WHODD), B2 Enhanced March 2021.
Study Data Tabulation Model (SDTM) and Analysis Data Model (ADaM) datasets will be 
prepared using Clinical Data Interchange Standards Consortium (CDISC) SDTM 
example, when rounding to the nearest integer, values 2:XX.5 will be rounded up to XX+ 1 ( e.g.,

Partial Dates  
Imputation of partial adverse event and concomitant medication dates are specified in 
Appendix 2, respectively. 
All data recorded on the case report form will be included in data listings.
4.4.
Data Conventions 
The precision of original measurements will be maintained in summaries, when possible. 
Quantitative safety laboratory tests containing less than (<) and greater than (>) symbols are test 
results that are below and above quantifiable limits, respectively. In order to retain these values 
for analysis purpose, the following will be imputed and stored within the analysis datasets: 
 For values with <, the imputed value will be the numeric portion × 0.9. 
 For values with >, the imputed value will be the numeric portion × 1.1. 
PK and PD imputation of values below the limitation of quantitation (BLQ) are specified in 
Section 8.7.1 and Section 8.8.1, respectively. 
Variables with a non-normal distribution that impacts the interpretation or validity of the planned 
analysis may have a data transformation applied (e.g., ln, log10).  
4.5. 
Standard Calculations 
Variables requiring calculation will be derived using the following formulas: 
 Days – A duration expressed in days between one date (date1) and another later date 
(date2) will be calculated using the following formulas:   
duration in days = date2 – 
 
duration in days = date2 – date1, where date1 <first administration date 
 Months – A duration expressed in months is calculated as the number of days divided by 
30.4375 
 Years – A duration expressed in years between one date (date1) and another date (date2) 
is calculated using the following formulas: 
duration in years = (date2 – 
n 
date 
duration in years = (date2 – date1)/365.25, where date1<first administration date 
 Body Mass Index (BMI) – BMI is calculated using height (cm) and weight (kg) using the 
following formula: 
BMI (kg/m2) = weight (kg) / ([height (cm)/100]2)

4.7.1. 
Windows  
Each visit will be denoted by its visit “Week”. The first dose day is denoted as Day 1. In data 
listings, the relative study day of all dates from first dose will be presented. 
In the event of unscheduled visits or early treatment termination (ET) assessments, these will be 
reassigned to a scheduled visit for analysis purposes according to Table 4 for on treatment 
assessments. If multiple assessments occur within a single visit window, after reassignment of 
unscheduled visits and ET assessments, the assessment closest to the target day of the visit 
window will be used in the analysis. If there is a tie, the later assessment will be used in the 
analysis.

4.7.2. 
Definition of Baselines 
The baseline value for statistical analyses of quantitative laboratory parameters is defined as the 
mean of all available evaluations, including any unscheduled or repeat assessments, prior to the 
first administration of study drug, unless otherwise specified.  If there is only one evaluation 
prior to the first administration of study drug, then the available data from this evaluation will be 
used as the baseline value.  
For glucose and lipid parameters, only assessments taken while fasting for at least 8 hours will 
be included in the baseline derivation.
The baseline value for analyses of qualitative parameters (e.g., normal/abnormal) is defined as 
the last evaluation prior to the first administration of study drug. 
The baseline value for analyses of height, weight, body mass index (BMI), waist circumference, 
and electrocardiogram parameters is defined as the last evaluation prior to the first administration 
of study drug. 
The baseline value for pharmacodynamic analytes is defined as the Week 0/Day 1 predose value. 
4.7.3. 
Definition of End of Treatment 
The End of Treatment value will be defined as the Week 12 value, either scheduled or windowed 
per Table 4.  If a Week 12 value is not available, the last non-missing on or before the last dose 
date will be used.

Prior and concomitant medications will be summarized separately and the number and 
percentage of patients in each treatment group who took at least one prior (concomitant) 
medication as well as the number and percentage of patients who took each type of medication 
will be summarized by Anatomic Therapeutic Class (ATC) Level 2, ATC Level 4, and preferred 
name for the Safety Analysis Set.  If a patient has more than one occurrence of the same 
preferred name, then the preferred name will be counted only once for that patient.  Similarly, if 
a patient has more than one preferred name within ATC Level 4 or ATC Level 4 within ATC 
Level 2, then the patient will be counted only once in that ATC Level 4 or ATC Level 2.

EFFICACY ANALYSES 
8.1.
Adjustments for Covariates
For comparison of treatment groups with respect to change and percent change from baseline, 
analysis of covariance (ANCOVA) and restricted maximum likelihood (REML) based mixed 
model repeated measures (MMRM) models will be used.  The corresponding baseline value will 
be used as a covariate in the model.   
8.2. 
Handling of Dropouts or Missing Data 
Primary analyses will be based on observed data. Sensitivity analyses will be conducted for 
patients who do not have data at the Week 12 visit, where the last on treatment value will be used 
for Week 12. 
8.3. 
Interim Analyses and Data Monitoring 
No data monitoring committees are planned for this study.
An interim analysis will be performed after all patients in Part 1 have completed Week 6 
assessments. Blinded adverse event and laboratory data will be reviewed.  PK and PD data will 
be provided to the Sponsor with a dummy subject identification and treatment assignment.  If 
robust VAP-1/SSAO activity suppression is observed, and available PK suggest a lower dose 
may also possibly lead to robust VAP-1/SSAO activity suppression, enrollment in Part 2 with 4 
mg TERN-201 may be initiated.  Additionally, if safety data indicates 10 mg TERN-201 is 
overall safe and well-tolerated and anticipated exposures with a higher dose remain below the 
exposure limit (see section 4.3 of the protocol), enrollment in Part 2 to assess a dose up to 20 mg 
TERN-201 in Part 2 may be initiated. 
Additionally, an interim analysis will be conducted after the completion of Part 1.  All data from 
Part 1 will be cleaned and locked prior to unblinding and analyses. 
8.4. 
Multicenter Studies 
The randomization is not stratified by site. Likewise, analyses of data will not be stratified by 
study site.

Multiple Comparisons/Multiplicity
There will be no adjustment for multiplicity. Statistical testing will be considered nominal, 
descriptive and exploratory. 
8.7. 
Pharmacokinetic (PK) Analyses 
Analyses of trough PK concentrations will use the PK Analysis Set. Analyses of intensive PK 
concentrations and PK parameters will use the PK/PD Substudy Analysis Set.  All PK endpoints, 
recorded and derived, will be presented in by-patient data listings. 
Plasma and urine TERN-201 and metabolite (TRN-001021 and TRN-001744) concentrations 
will be used as supplied by the analytical laboratory for PK analysis. The units of concentration 
and resulting PK parameters, with amount or concentration in the unit, will be presented as they 
are received from the analytical laboratory, with the exception of metabolite to parent ratios 
which will be corrected for differences in molecular weight. Urine volume will be presented with 
urine concentrations.  Urine collection dates and times from the EDC will be used for analyses, 
otherwise plasma collection dates and times from the central vendor will be used.
Blood and urine samples will be collected at the timepoints specified in Appendix 2 of the study 
protocol.  
8.7.1. 
Below the Quantification Level (BLQ) Values 
Plasma concentration values that are BLQ will be set to zero, with defined exceptions as follows: 
 Any embedded BLQ value (between 2 quantifiable concentrations) and BLQ values 
following the last quantifiable concentration in a profile will be set to missing for the 
purposes of PK analysis. If an embedded BLQ value is considered anomalous within 
the concentration time profile, this value will be excluded as well. 
 If there are late positive concentration values following 2 BLQ concentration values 
in the apparent terminal phase, these values will be evaluated. If these values are 
considered to be anomalous (see Section 8.9.2), they will be set to missing. 
If an entire plasma concentration-time profile is BLQ, the profile will be excluded from the PK 
analysis.  
Urine concentrations below lower limit of quantification (LLOQ) will be treated as numerical 
zero for the calculation of the urine parameters. 
8.7.2. 
Anomalous Values 
If a value is considered to be anomalous due to being inconsistent with the expected PK profile, 
it may be appropriate to exclude this point from the PK analysis. However, the exclusion of data 
must have strong justification and will be documented in the raw data and CSR.

Concentration-Time Data 
Individual plasma TERN-201 and metabolite (TRN-001021 and TRN-001744) concentration 
data will be listed separately for trough concentrations (PK Analysis Set) and trough and 
intensive concentrations (PK/PD Substudy Analysis Set).  Concentrations will be summarized by 
nominal sampling time point and treatment with descriptive statistics (number of non-missing 
observations, arithmetic mean, arithmetic SD, arithmetic coefficient of variation [CV%], median, 
Q1, Q3, minimum, maximum, geometric mean and geometric CV%). The number of values 
below quantification limit (BLQ) will be presented for all patients and separately for PK/PD 
substudy patients. Individual urine TERN-201 and metabolite (TRN-001021 and TRN-001744) 
concentrations and sample volume will be listed for each patient. 
The following rules will be applied in the presentation of plasma concentration data if there are 
values that are BLQ or if there are missing values (e.g., no result [NR]) in a plasma concentration 
data series to be summarized. 
 For the calculation of summary statistics, BLQ values will be set to zero. 
 For the calculation of PK parameters, BLQ values will be set to zero prior to the first 
measurable concentration and set to missing after a measurable concentration is observed.
 If an embedded BLQ value is considered anomalous within the concentration time 
profile, this value will be excluded from the summary statistics. 
 Where there is NR, these will be set to missing. 
 If there are less than three values in the data series, only the minimum, maximum and 
number of observations will be presented. The other summary statistics will be denoted 
as not calculated (NC). BLQ is considered a value. 
 If all the values are BLQ, then the arithmetic mean, arithmetic SD, median, minimum and 
maximum will be presented as zero, and the geometric mean and geometric CV% will be 
denoted as NC. 
 If the value of the arithmetic mean or median is below the lower limit of quantification, 
these values will be presented as zero and the geometric mean and geometric CV% will 
be denoted as NC. 
Individual patient and arithmetic mean concentration-time profiles, for TERN-201 and its 
metabolites (TRN-001021 and TRN-001744), for each TERN-201 dose, will be presented
graphically on linear and logarithmic concentration scales separately for trough concentrations 
(PK Analysis Set) and trough and intensive concentrations (PK/PD Substudy Analysis Set) for 
Week 0/Day 1 and Week 12.  A reference line for LLOQ will be included on graphs. 
Concentration data in listings will be presented to the same number of significant figures as 
provided by the analytical laboratory. Descriptive statistics will be displayed according to the 
rules outlined in Section 3.2.

purposes of Pop PK modeling. If Pop PK modeling is performed, the process will be described in 
a separate analysis plan. 
For the purposes of this SAP, plasma PK parameters will be computed for the PK/PD sub-study 
patients only. Plasma PK parameters for TERN-201 and its metabolites (TRN-001021 and TRN-
001744) will be calculated from the individual plasma concentrations using a non-compartmental 
approach for Week 0/Day 1, Week 6, and Week 12.  Week 0/Day 1 and Week 6 will include pre 
dose and all post dose assessments prior to the next dose.  Week 12 will include pre dose and all 
post dose assessments.  The actual PK sampling times will be used for the PK analysis. If actual 
PK sampling times are missing, nominal times will be used. If the 24 hr sample is missing at 
Week 6 or Week 12, the predose sample concentration may be re-used for the 24 hr sample for 
the purposes of calculating PK parameters, if appropriate.
Table 6 presents the plasma PK parameters for TERN-201 and its metabolites (TRN-001021 and 
TRN-001744) to be calculated.

Pharmacokinetic Parameter Data Handling 
8.7.4.2. 
Calculation of AUC 
AUCs will be calculated using linear up / log down trapezoidal rule. For any partial AUC 
determination (i.e., AUC over a dosing interval), nominal time will generally be used for the end 
of the interval. Actual times for partial AUC intervals may be used at the discretion of the 
pharmacokineticist.  
The minimum requirement for the calculation of AUC will be the inclusion of at least three 
consecutive plasma concentrations above the LLOQ, with at least one of these concentrations 
following Cmax.
8.7.4.3. 
Criteria for Calculation and Goodness of Fit 
z, t1/2, AUC0- , CL/F and CLss/F, Vz/F and Vss/F, and LR will only be reported if the 
following criteria for the terminal elimination phases (log-linear phase) for the concentration-
time data are met:
 
A minimum of 3 measurable concentration-time-points during the log-linear portion of the 
terminal elimination phase (after Tmax), excluding Cmax. 
 
r²adj 
80 for the regression of the log-concentration time data during the terminal 
elimination phase.
Negative slope for log regression fit. 
AUC0- values where the percentage extrapolation is greater than 30% will be reported and 
flagged but excluded from descriptive statistics.  Parameters affected by AUC0- such as t1/2, 
CL/F, Vz/F, and LR will be handled the same way as AUC0-
 
Additional analyses will be performed as deemed necessary upon review of the data.
8.7.5. 
Statistical Methods for Pharmacokinetic Parameters
Plasma PK parameters will be summarized by treatment group using descriptive statistics 
(number of non-missing observations, arithmetic mean, SD, median, Q1, Q3, minimum, 
maximum, geometric mean, and geometric CV%).   
For the calculation of summary statistics, all NR and not calculated (NC) values in a data series 
will be set to missing.

VAP-1/SSAO Activity Levels and Methylamine Concentration Time Data 
Individual plasma VAP-1/SSAO activity levels and methylamine concentration data will be 
listed separately for trough timepoints (PD Analysis Set) and trough and intensive timepoints 
(PK/PD Substudy Analysis Set).  VAP-1/SSAO activity levels and methylamine concentrations
will be summarized by nominal sampling time point and treatment group with descriptive 
statistics (number of non-missing observations, arithmetic mean, SD, median, Q1, Q3, minimum, 
maximum, geometric mean and geometric coefficient of variation [CV%]). The number of 
values BLQ will be presented for all patients and separately for PK/PD substudy patients.  
The following rules will be applied in the presentation of plasma VAP-1/SSAO activity levels 
and methylamine concentration data if there are values that are BLQ or if there are missing 
values (e.g., no result [NR]) in a data series to be summarized. 
 For the calculation of summary statistics, BLQ values will be set to ½ × BLQ. 
 Where there is NR, these will be set to missing. 
 If there are less than three values in the data series, only the minimum, maximum and 
number of observations will be presented. The other summary statistics will be denoted 
as not calculated (NC). BLQ is considered a value. 
 If all the values are BLQ, then the arithmetic mean, arithmetic SD, median, minimum and 
maximum will be presented as ½ × BLQ, and the geometric mean and geometric CV% 
will be denoted as NC. 
Individual patient, arithmetic mean VAP-1/SSAO activity levels and methylamine concentration

separately using the PD Analysis Set for trough timepoints and using the PK/PD Analysis Set for 
trough and intensive timepoints. Baseline is defined as the Week 0/Day 1 pre-dose value.
Analyses of change (and separately percent change) from baseline will be carried out using an 
ANCOVA model at time point with change (and separately percent change) from baseline as the 
dependent variable including treatment group and randomization strata as fixed effects and 
baseline as a covariate.   
The estimates of least-square (LS) means, standard errors (SE), and 90% and 95% CIs will be 
presented by treatment group.  Estimates of the LS mean difference for each pairwise 
comparison will be presented with associated the standard error of the difference, and 90% and 
95% CIs of the difference.
Figures of LS mean (±SE) change from baseline, and percent change from the ANCOVA model
will be presented over time by treatment group.

Dose response will also be evaluated using a REML based MMRM.  The dependent variable will 
be the percent change (separately for change) from baseline for plasma VAP-1/SSAO activity 
and methylamine.  The model will include the following fixed effects:
Treatment group (4 levels: placebo [0 mg], 4 mg, 10 mg, 20 mg)
 Categorical time  
Treatment group by time interaction
Baseline value
An unstructured covariance model will be used.  If the computational algorithm fails to 
converge, the following structures will be executed:  heterogeneous Toeplitz, heterogeneous 
First-Order Autoregressive [AR (1)], heterogeneous compound symmetry (HCS), Toeplitz, 
AR(1), and compound symmetry (CS).  The covariance structure converging to the best fit, as 
determined by Akaike’s information criterion (AIC, the smaller the AIC value the better the 
model fit), will be used.  If the model converges with an unstructured covariance matrix, the 
Kenward and Roger method will be used to calculate the denominator degrees of freedom for the 
test of fixed effects. If a structured covariance is used, then a robust sandwich estimator will be 
utilized for estimating the variance of the treatment effect estimate.

Exposure Response Analyses
The plasma PK parameters AUCtau, Cmax, and Ctau will be used to evaluate exposure-response.  
PK parameters will be set to 0 for the placebo group for the purpose of PK/PD.

Pharmacodynamic exposure-response analyses of plasma VAP-1/SSAO activity and 
methylamine concentration PD parameters will be performed using several exposure-response 
models for the PK/PD Analysis Set, including but not limited to linear, quadratic, exponential, 
and Emax.  The best fit significant model will be chosen based on AIC, the smaller the AIC value 
the better the model fit. 
Additional exposure-response and dose-response (as applicable) analyses may be explored for 
baseline patient characteristics such as sVAP-1, BMI, diabetes mellitus, or other characteristics 
or additional efficacy, safety, and PD endpoints, as needed.  These analyses will be described in 
a separate document.

Exploratory Efficacy Analyses  
8.10.1. 
Magnetic Resonance Imaging 
MRIs will be evaluated by a central reader. The following analyses of MRI will use the Efficacy 
Analysis Set. Sensitivity analyses using the PP and Treatment Completer Analysis Sets will be 
presented if the analysis set differs from the Efficacy Analysis Set by more than 10% total. 
8.10.1.1. Corrected T1 (cT1) 
cT1 related to the amount of extracellular fluid present in the liver parenchyma. cT1 is derived 
from T1 and T2* maps. T1 is a measure of the longitudinal (spin-lattice) relaxation time, 
measured in milliseconds (msec), of a given substance. The T1 of a tissue depends on its free 
water content, which relates to the proportion of the extracellular fluid in the tissue. 
Proton-dense tissues with a low water content, such as fat, have very short T1 values, while 
tissues with a high water content, such as muscle and the spleen have much longer T1 values. 
When tissue is inflamed or scarred (fibrotic), changes in the structural organization of the tissue, 
due to tissue remodeling, mean that the water content increases, leading to longer T1 values. 
cT1 is measured in milliseconds (msec).  The cT1 metric is calculated from all pixels with whole 
slice ROIs placed on the cT1 parametric map. The cT1 metric is displayed as a median and IQR, 
the median will be used in all analyses. 
Analyses of cT1 will be based on the Efficacy Analysis Set. Descriptive statistics of the cT1 
values, change from baseline, and percent change will be summarized by treatment group and 
visit.   
Analyses of change (and separately percent change) from baseline will be carried out using an 
ANCOVA model at each scheduled visit with change (and separately percent change) from 
baseline as the dependent variable including treatment group and randomization strata as fixed 
effects and baseline as a covariate.   
The estimates of least-square (LS) means, standard errors (SE), and 90% and 95% CIs will be 
presented by treatment group.  Estimates of the LS mean difference for each pairwise 
comparison will be presented with associated the standard error of the difference, and 90% and 
95% CIs of the difference. 
The primary analysis of change (and separately percent change) at Week 12 will be carried out 
using available observed data only, without imputation for missing data. The same ANCOVA

model will be used to present the last on treatment value for Week 12, to be labelled as “Week 
12/End of Treatment”.  For patients who complete Week 12, the Week 12 value will be used.  
For patients who do not complete treatment, the last value on treatment will be used. 
The distribution of change (percent change) values will be evaluated visually for normality 
assumptions.  If normality assumptions are violated, first the data will be natural log transformed 
and the log transformed data evaluated for normality.  If the data are not normally distributed, a
Wilcoxon Rank Sum Test will be used to compare treatment groups.  The median differences 
and 90% and 95% CIs of the median differences between treatment groups will be constructed 
using Hodges-Lehmann estimate.   
Sensitivity analyses using the PP and Treatment Completer Analysis Sets will be presented if the 
analysis set differs from the Efficacy Analysis Set by more than 10% total. 
cT1 will be categorized as low (<800 msec), elevated (800 – 900 msec), and high (>900 msec).  
A shift table from baseline to Week 6 and baseline to Week 12 will be presented by treatment 
group. 
In addition, cT1 responders will be defined as any patient with a decrease of at least 80 msec. 
Non-responders will be defined as any patient who did not have at least an 80 msec decrease.  
For both endpoints, the number and percentage, with associated two-sided exact (Clopper-
Pearson) 90 and 95% CIs, of patients in each category will be presented by treatment group at 
each post-baseline visit.  A Chi-square test at each post-baseline visit will be used to compare 
each pairwise comparison between placebo and each active dose of TERN-201. 
The number and percentage of patients who are responders on cT1 and ALT will be summarized 
and analyzed in the same manner as responders. 
8.10.1.2. Liver Fat Content by MRI Proton Density Fat Fraction (PDFF) 
Liver fat content (LFC) or proton density fat fraction (PDFF) is an estimate of the percentage of 
fat within a tissue. It is defined as the proportion of the mobile proton density in the liver 
is expressed as a percentage (%). The PDFF metric on the quantitative analysis output is a 
summarized metric from the individual pixels within all of the region of interests (ROIs) placed 
on the PDFF parametric map or an average of all the pixels within the contour generated by 
automatic liver segmentation. The PDFF metric is displayed as a median and interquartile range 
(IQR), the median will be used in all analyses. 
Analyses of liver fat content (LFC) by MRI by MRI-PDFF will be based on the Efficacy 
Analysis Set. For the purposes of LFC analyses, absolute change is equivalent to change and 
relative change is equivalent to percent change (see Section 4.5). Descriptive statistics of the 
LFC by MRI-PDFF results, absolute change from baseline, and relative change will be 
summarized by treatment group and visit.  
LFC by MRI-PDFF will be analyzed in the same manner as LFC (Section 8.10.1.1).  LFC by 
MRI-PDFF responders will be defined as any patient with a relative decrease of at least 30% 
-30%). Non-responders will be defined as any patient who did not have at least a 30% 
relative decrease (i.e., >-30%). The number and percentage, with associated two-sided exact 
(Clopper-Pearson) 90% and 95% CIs, of patients in each category (response, nonresponse) will 
attributable to fat. PDFF is quantified from the ratio offat/(fat+water) components in images and

Transient Elastography 
Liver stiffness and CAP are measured by transient elastography. Descriptive statistics of 
biomarker values, change from baseline, and percent change from baseline will be presented by 
treatment group for each visit, at which data are collected, using the Efficacy Analysis Set.   
Change (and separately for percent change) from baseline in liver stiffness will be analyzed 
using the same ANCOVA model presented in Section 8.10.1.1 for each post-baseline and follow 
up visit using observed data only.  Sensitivity analyses using the PP and Treatment Completer

The change (and separately percent change) from end of treatment to follow up visit (Week 16) 
will be summarized by treatment group.  For patients who complete Week 12, the Week 12 value 
will be used for End of Treatment.  For patients who do not complete treatment, the last value on 
treatment will be used for End of Treatment. Descriptive statistics of ALT values, change from 
end of treatment, and percent change from end of treatment will be presented by treatment group 
for each visit using the Efficacy Analysis Set.   
Change (and separately for percent change) from end of treatment in ALT will be analyzed using

Adverse Events 
Adverse event (AE) verbatim terms on eCRFs will be mapped to preferred terms (PT) and 
system organ classes (SOC) using MedDRA.  AE severity will be categorized using the National 
Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE, Version 5). 
All AEs will be listed, but summaries will be restricted to TEAEs, defined as any AE with a start 
date on or after the date of first administration of study drug through 30 days after the last 
administration of study drug or through the Follow-Up Period (Week 16).  Related SAEs after 
Week 16 will be considered TEAEs. If it cannot be determined whether an AE is treatment 
emergent due to a partial onset date, then it will be counted as such. Methodology for imputation 
of partial AE start and stop dates is described in Appendix 2. Each summary will be displayed by 
treatment group.

Clinical Safety Laboratory Evaluations 
All laboratory assessments are specified in Appendix 1 of the study protocol. Laboratory 
parameters will be summarized in conventional units. Coagulation parameters, hemoglobin A1c, 
direct bilirubin, and indirect bilirubin will not be summarized. 
Quantitative serum chemistry, fasting lipids, and hematology results will be summarized by 
treatment group using descriptive statistics at baseline and at each post-baseline visit.  The 
change and percent change from baseline will also be summarized.  
Values determined to be erroneous will be documented in the trial master file and analysis data 
reviewer’s guide.  Erroneous values will not be included in summary tables or analyses but will 
be included in patient listings. 
All clinical safety laboratory data will be presented in by-patient data listings. A separate listing 
for central laboratory normal ranges, by lab category, lab test, lab parameter, sex, and age, will 
be presented. Any local laboratory normal ranges for COVID-19 will be presented separately.
9.3.1. 
Treatment Emergent Abnormalities 
Quantitative laboratory tests will be assigned grades based on National Cancer Institute Common 
Terminology Criteria for Adverse Events (NCI CTCAE) Version 5. For each applicable 
laboratory test, a treatment emergent abnormality will be defined as a post-baseline through 
Week 16 CTCAE grade worsening 
The number and percentage of patients overall and by laboratory test, with any treatment 
emergent laboratory abnormality, CTCAE worsening 
  
Listings will be presented for any patient with any treatment emergent laboratory abnormality 
(any increase in CTCAE grade). Normal ranges provided by the central laboratory will be 
presented in a listing.

Assessments of Potential Drug Induced Liver Injury  
Modified Hy’s rule by Bjornsson (Bjornsson 2005) is defined as patients with ALT or AST 
values >3x ULN and total bilirubin >2x ULN (based on the same blood draw of ALT, AST, and 
total bilirubin while on study drug, or within 30 days of last received dose) will be used to assess 
the potential for study drug-induced liver toxicity. Any patient meeting the criteria will be 
presented in a by-patient listing.    
The criteria for increased laboratory monitoring or consideration for study drug discontinuation 
on study are specified in protocol appendix 3 and will be included in the analysis dataset and 
listed.    
9.3.3. 
Shifts in CTCAE Grade
Quantitative laboratory tests will be assigned grades based on National Cancer Institute Common 
Terminology Criteria for Adverse Events (NCI CTCAE) Version 5. Shifts in CTCAE grade of 
laboratory tests will be presented from baseline to worst post-baseline value. Summaries will 
present the number and percentage of patients with shifts in laboratory grade by treatment group. 
Denominators for percentages will be the number of patients with non-missing data at the 
specific assessment and baseline. 
Some lab tests include additional clinical criteria which cannot be determined programmatically. 
Table 10 below specifies the grade with clinical criteria in italics. The text in italics will not be 
considered when assigning grades programmatically.
