Approximately 96 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 
1:1:1:1 into 4 groups receiving 5 mg (n = 24), 10 mg (n = 24), 15 mg (n = 24) TERN-101 tablets, 
or matching placebo (n = 24) orally once daily.  
Of the 96 patients randomized, 24 patients will take part in an intensive PK and 
pharmacodynamic (PD) collection after the first dose and after the last dose of study drug. This 
includes 6 patients at each TERN-101 dose level, and 6 patients in the placebo group. 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 24 weeks, consisting of an 8-
week Screening Period, a 12-week Treatment Period and a 4-week Follow-up Period.  
Disclosure Statement:  
This is a parallel-group treatment study.  
Number of Patients: 
Approximately 96 patients will be randomly assigned to treatment with TERN-101 tablet or 
matching placebo. 
Patients who are randomized but do not receive study drug for any reason may be replaced.  
Study Centers Planned:  
Approximately 40 centers in the United States. 
Intervention Groups and Duration: 
The total study duration will be approximately 24 weeks, consisting of an 8-week Screening 
Period, a 12-week Treatment Period and a 4-week Follow-up Period.  
Screening Period 
The 8-week Screening Period initiates upon signing an Informed Consent, at which point 
eligibility criteria will be reviewed. Each eligible patient will be scheduled for Week 0/Day 1.  
Treatment Period 
The 12-week double-blind, randomized Treatment Period will initiate at Week 0/Day 1 after 
confirming eligibility. The blinded study drug (TERN-101 tablet or placebo) will be orally 
administered once daily in the morning, without regard to food.

Patients will return to the site at Weeks 2, 4, 6, 8, and 12 for safety and laboratory assessments. 
Study drug will be dispensed at Week 0/Day 1, Week 4, and Week 8. Week 12 is the last day of 
treatment.  
Intensive PK/PD sampling will be performed in 24 patients participating in the PK/PD sub-study
after the first dose (Week 0/Day 1) and after the last dose of study drug (Week 12).  
Imaging (MRI-PDFF) will be completed at Week 0, Week 6, and Week 12. An MRI is 
performed at early termination (ET) only if not done within the prior 4 weeks, and the patient has 
had at least 4 weeks of dosing.   
Follow-up Period 
All patients will return to site for follow up safety assessments at Week 16. 
If study drug is permanently discontinued for any reason outlined in Section 7, the patient will be 
encouraged to 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.

Introduction 
2.1. 
Overview of Nonalcoholic Steatohepatitis (NASH) and Unmet Need  
This study is a randomized, double-blind, placebo-controlled, parallel-group, Phase 2a study to 
evaluate the safety, tolerability, efficacy, and PK of various doses of TERN-101 in non-cirrhotic 
presumed NASH patients. TERN-101 is a highly selective and potent small molecule agonist of 
FXR in development for the treatment of patients with NASH.

TERN-101 is a non-steroidal, synthetic small molecule 
 and is 
formulated for oral administration in capsule or tablet form. TERN-101 is a potent FXR agonist. 
As a selective and potent nonsteroidal, non-bile acid FXR agonist, TERN-101 may offer a 
unique safety and efficacy profile to benefit the NASH patient population. As summarized

below, nonclinical studies and Phase 1 clinical studies of TERN-101 support its potential utility 
as a disease-modifying treatment for NASH. 
2.2.2. 
Summary of Nonclinical Studies 
 
 
 
 
 
  
In mouse NASH models, TERN-101 inhibited 7-DC4 and significantly reduced NAFLD 
activity score (NAS) and liver fibrosis area. NAS was markedly reduced by all doses of TERN-
101 tested (Figure 1, left panel) with an 80% reduction from baseline at 100 mg/kg (mpk). 
Steatosis was reduced to healthy control (lean mice) levels at 30 mpk (Figure 2, left), and 
hepatocellular ballooning was reduced to healthy control levels at 100 mpk (Figure 2, middle).  
Hepatic inflammation was also reduced in TERN-101 treated mice (Figure 2, right). The 
improvement in liver histology correlated with a reduction in liver triglycerides, serum lipids and 
the liver-related enzymes ALT and AST. These results indicate potent FXR agonist activity and 
support that TERN-101 has the potential for use in the treatment of NASH.

TERN-101 5-mg tablet and at 1.52 hours for TERN-101 25-mg tablet. Transient increases in 
FGF-19 concentrations and dose-dependent decreases in 7-Į-C4 concentrations were observed 
after single doses of TERN-101 tablets. Administration of TERN-101 (5 mg) tablet with food 
delayed the time of maximal plasma concentrations (from ~1 hour fasted to ~4 hours fed) but did 
not result in significant differences in exposure as assessed by AUC. 
 
 
 
 
 
Safety findings from the 4 clinical studies showed that TERN-101 was well-tolerated overall. 
AEs were predominantly mild and transient. The predefined maximum tolerated dose was not 
reached in any study. The overall AE incidence was generally balanced between dose groups. 
Following multiple doses of TERN-101 capsules of up to 400 mg, no TEAEs were attributable to 
TERN-101 on the basis of frequency, dose-relationship, or expected pharmacology. Pruritus was 
not reported by any of the 119 human subjects who have received TERN-101 to date. 
 
 
 
 
 
  No 
transaminase elevations > 1.5 times upper limit of normal were observed in the subsequent 
completed repeat dose study (TERN101-US-A101) 
 or Study TERN101-US-A104). In the 2 completed repeat dose Phase 1 TERN-101 
studies, no consistent trends in changes from baseline in LDL cholesterol were observed with 
TERN-101. In the recently completed Phase 1 study TERN101-US-A104, there was no 
consistent pattern of LDL change on-study; several subjects had elevated levels prior to dosing, 
and LDL remained at overall similar levels on-study. 
Additional information on available TERN-101 clinical study results, including clinical 
pharmacology and dose-selection considerations, is provided 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, and lipid levels will be obtained and monitored for 
abnormalities in a blinded fashion.  
Overall, based on past experience of clinical studies of TERN-101 in healthy volunteers, the 
benefit/risk assessment is considered to be positive for patients to be enrolled in this study. More 
detailed information about the known and expected benefits and risks and reasonably expected 
adverse events of TERN-101 may be found in the Investigator’s Brochure.

Study Design 
4.1. 
Overall Design 
This study is a multicenter, randomized, double-blind, placebo-controlled, parallel-group study. 
Approximately 96 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 
1:1:1:1 into 4 groups receiving 5 mg (n = 24), 10 mg (n = 24), 15 mg (n = 24) TERN-101 tablet 
or matching placebo (n = 24) orally once daily.  
Of the 96 patients randomized, 24 patients will take part in an intensive PK and PD collection 
after the first dose and after the last dose of study drug. This includes 6 patients at each 
TERN-101 dose level, and 6 patients in the placebo group. Patients who are not participating in 
the PK/PD sub-study will have trough PK/PD sampling only.  
The total study duration will be approximately 24 weeks, consisting of an 8-week Screening 
Period, a 12-week Treatment Period and a 4-week Follow-up Period.  
4.2. 
Scientific Rationale for Study Design 
The study will enroll male and female patients with non-cirrhotic presumed NASH in order to 
obtain evidence of safety, preliminary efficacy, PK, and PD of 3 dose levels of TERN-101. The 
multiple-dose design of this study is randomized and double-blinded to minimize bias and to 
enable efficient evaluation of different dose levels. The placebo control is included to facilitate 
identification of effects related to administration of TERN-101 rather than the study procedures, 
disease, or situation. The study duration will allow characterization of the safety and tolerability 
of TERN-101 with 12 weeks of dosing as well as initial assessment of effect of TERN-101 on 
efficacy parameters in a NASH population. 
4.3. 
Justification for Dose 
Based on PK results from TERN101-US-A104 Phase 1 study in healthy subjects, the tablet 
formulation of TERN-101 was dose linear in the range of 5 mg to 25 mg, with AUC0-t of  
475 (±161) ng*hr/mL and 2890 (±720) ng*hr/mL for 5 and 25 mg tablets, respectively. 
 
 
Evidence of FXR target engagement was seen for doses ranged from 5 mg to 
25 mg tablets of TERN-101 (see Section 2.2.3). The doses selected for this study of 5 mg, 
10 mg, and 15 mg TERN-101 tablets are expected to achieve FXR target engagement and will 
allow for characterization of the safety and efficacy of TERN-101 across these dose levels. 
There was no significant impact of food intake on TERN-101 PK based on results from 
Study TERN101-US-A104, thus TERN-101 can be dosed without regard to food intake.

6.4. 
Measures to Minimize Bias: Randomization and Blinding 
Patients will be randomized to TERN-101 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 96 patients will be randomized at an overall ratio of 1:1:1:1 into 4 groups 
receiving 5 mg (n = 24), 10 mg (n = 24), 15 mg (n = 24) TERN-101 tablet, or matching placebo 
(n = 24). Randomization will ensure 6 patients at each TERN-101 dose level and 6 patients in the 
placebo group are assigned to the PK/PD sub-study. 
Investigators, patients, all study personnel, and the Sponsor will remain blinded to each patient’s 
assigned dose group throughout the course of the study. 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.  
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 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. Compliance will be assessed 
 
 
   
 
 
 
 
 
 
6.6. 
Concomitant Therapy 
Any medication or vaccine (including over-the-counter or prescription medicines, vitamins, 
and/or herbal supplements) that the patient is receiving at the time of randomization or receives 
during the study must be recorded at each study visit along with: 
x Reason for use 
x Dates of administration including start and end dates 
x Dosage information including dose and frequency

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 intensity, 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.

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

Assessment of Pruritus 
For patients who report AEs consistent with pruritus, photographs of the affected area(s) will be 
taken at the discretion of the Investigator (eg, if there are visible skin lesions; photos that would 
identify the patient, ie, of the entire face, will be avoided), and a qualified staff member will 
administer the Pruritus Numerical Rating Scale (Appendix 8) at each study visit where pruritus is 
reported or noted to be ongoing. If pruritus is reported, the clinical site will provide details on 
these events in the eCRF.  
The Investigator will be asked to provide an assessment of the severity of the AE using the NCI 
CTCAE v5.0 categories for pruritus as follows:  
x 
Grade 1: Mild or localized; topical intervention indicated.

The baseline value is defined to be the latest assessment value prior to the first dose of study 
drug, unless specified in the SAP for some particular tests. 
Missing values will not be imputed. 
Data analysis will be performed using SAS® Version 9.4 or higher. 
SDTM (Study Data Tabulation Model) and Analysis Data Model (ADaM) datasets will be 
prepared using Clinical Data Interchange Standards Consortium (CDISC) SDTM IG Version 3.2, 
ADaM Version 2.1, and CDISC ADaM Implementation Guide Version 1.1.  
9.4.2. 
Primary Endpoints 
Safety parameters will be listed and summarized using descriptive statistics. The safety 
parameters will include AEs, and treatment emergent clinical laboratory parameters. No formal 
statistical testing is planned.  
Reported AEs will be coded using the latest version of Medical Dictionary for Regulatory 
Activities (MedDRA Version 22.1, or most recent) and graded for severity according to NCI 
CTCAE, Version 5.0.  
All TEAEs will be listed and summarized by MedDRA Preferred Term and System Organ Class, 
as well as by maximum intensity and study drug causality, in frequency and percentage. 
Summaries of treatment-emergent SAEs, TEAEs related to study drug, TEAEs resulting in study 
drug discontinuations and death will be produced. 
Grade shifts in laboratory tests will be summarized in addition to AEs. Absolute or relative 
changes from baseline of quantitative measurements will be analyzed by treatment group and 
timepoints and presented in shift tables, if applicable. Laboratory abnormalities will be graded 
according to NCI CTCAE Version 5.0.  
The number and percentage of subjects experiencing treatment-emergent graded lab toxicities 
will be summarized by treatment group and severity grade.  
Further details on the analysis of safety parameters will be provided in the SAP. 
9.4.3. 
 Secondary Endpoints 
9.4.3.1. 
Change from Baseline in ALT Levels at 12 Weeks 
The secondary efficacy variable is the percent change from Baseline in the ALT after 12 weeks 
of treatment in patients treated with either TERN-101 or matching placebo. The mean percent 
change from baseline in ALT in each TERN-101 group will be compared with placebo 
separately without controlling for any family-wise error rate (overall type I error) by using 
analysis of covariance (ANCOVA) methods. The percent change from baseline in ALT will also

Appendix 9: 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] antibody required; Immunoglobulin M [IgM] antibody recommended in addition).  
x Prior to central laboratory testing availability, antibody testing may be omitted if not 
available locally. 
At Week 0, 6, and 12:  
x Testing for past infection via antibody testing (IgG required; IgM recommended in 
addition) if prior IgG was negative.  
x Prior to central laboratory testing availability, testing for active infection (e.g. molecular 
test such as PCR or viral antigen serology) may replace antibody testing if the latter is not 
available locally. 
x If Week 0 occurs within 2 weeks of Screening, site may omit repeat SARS-CoV-2 testing 
at PI discretion. 
x If IgM antibody test is positive, may reflex to test for SARS-CoV-2 active infection at 
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, once available via the 
central laboratory), 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.
