Page 31. Section 9.1.4 Clinical Safety Laboratory Assessments 
The Investigator must review the laboratory report, document this review, and record any clinically relevant 
changes (as per the reference laboratory values [Appendix 6]) occurring during the study in the AE section of 
the CRF. 
All laboratory tests with values considered clinically significantly abnormal during participation in the study 
should be repeated until the values return to normal or baseline or are no longer considered clinically significant 
by the Investigator or medical monitor as per the reference laboratory values in Appendix 6. 
If laboratory values from non-protocol specified laboratory assessments performed at the institution’s local 
laboratory require a change in participant management or are considered clinically significant by the Investigator 
as given in Appendix 6 (e.g., SAE or AE or dose modification), then the results must be recorded in the CRF.

Amendment 1 
 
Dose-limiting toxicity AEs will be defined as Grade ≥3, treatment-emergent, treatment-related laboratory 
abnormalities (Appendix 6) or AEs per the grading system by US Department of Health and Human Services 
(CTCAE, Version 5.0). 
 
The following Stopping Criteria will be used: 
 
Clinical Findings: 
 
1. Anaphylaxis or Grade ≥3 skin rash or pruritis 
 
2. Grade ≥3 nausea, emesis or diarrhea 
 
Laboratory Findings: 
 
1. Evidence of new onset of acute renal or hepatic failure, defined by increases in BUN, creatinine, or LFTs 
(AST, ALT, Alkaline phosphatase) that reflect new evidence of Grade 3 thresholds for liver function tests, 
for creatinine, and for electrolytes attributable to the administration of drug in the context of the 
Investigator’s evaluation.  
 
2. Evidence of acute infection or inflammation, defined by changes in the WBC and differential indices, 
attributable to the administration of drug in the context of the Investigator’s evaluation.  
 
3. Any “unexpected” Grade ≥3 Laboratory test result.  
  
If one of the above clinical or laboratory criteria for stopping occurs in any subject, further study recruitment and 
subject dosing will be halted until a full safety assessment can be completed.  Unblinding of the affected subject 
will be performed and the PI and Sponsor will review the totality of clinical data and any other circumstances 
possibly related to the “Stopping Criteria” findings to determine if the study can be resumed, modified, or will 
be permanently terminated.

ANA001 is a new formulation containing 250 mg niclosamide per capsule. Although other formulations 
containing niclosamide (ANA001) have been studied for tapeworm infections and other potential human uses, 
limited systemic PK/PD data exists in the literature. To ensure proper systemic levels of niclosamide are 
achieved for therapeutic effect, a SAD/MAD study with ANA001 capsules is necessary.

Synopsis 
Protocol Title: A Randomized, Double-Blind, Single and Multiple Ascending Dose Study to 
Assess the Safety and Pharmacokinetics of ANA001 in Healthy Adults 
Short Title: A single ascending dose (SAD) and multiple ascending dose (MAD) PK study of 
ANA001 in healthy adults 
Rationale: 
ANA001 is a new formulation containing 250 mg niclosamide per capsule. Although other 
formulations containing niclosamide (ANA001) have been studied for tapeworm infections and 
other potential human uses, limited systemic PK/PD data exists in the literature. To ensure proper 
systemic levels of niclosamide are achieved for therapeutic effect, a SAD/MAD study with 
ANA001 capsules is necessary. 
Objectives and Endpoints 
Objectives 
Endpoints 
Primary 
 
• To assess safety and tolerability of 
single oral daily doses of ANA001 
(1000 mg, 2000 mg and 3000 mg) 
• To assess safety and tolerability of 
multiple daily oral doses (twice daily 
[BID] or thrice daily [TID]) of 
ANA001 for 7 days 
• Incidence of adverse events (AEs), 
serious AEs (SAEs), study drug 
discontinuation due to an AE (MAD 
portion only), use of concomitant 
medications, and change from baseline 
in clinical laboratory tests, vital signs, 
electrocardiograms (ECG), and 
physical examinations 
Secondary 
 
• To assess the PK of single and 
multiple doses of ANA001 
• AUC0-t, AUC0-last, AUC0-∞ (SAD 
only), Cmax, tmax, t1/2, CL/F, Vz/F 
Overall Design: 
This is a randomized, double-blind study to be conducted in two parts: single ascending dose 
(SAD) and multiple ascending dose (MAD). Potential participants for each part will undergo 
screening procedures within 30 days of enrolment.

On Day -1, eligible participants will be randomly assigned to active drug or placebo in an 8:2 ratio. 
On Day 1, following an overnight fast of at least 10 hours, participants will receive their assigned 
treatment (1000 mg, 2000 mg, or 3000 mg of ANA001) with a standardized light meal (500 to 
750 cal).  A baseline ECG will be performed at Screening and at 3 hours after dosing. Blood 
pressure and heart rate will be measured every 8 hours while confined to the clinic. Blood for PK 
will be collected before dosing and at 0.5, 1, 2, 4, 6, 8, 10, 12 and 24 hours after dosing. Participants 
will be discharged on Day 2 following the 24-hour PK sample and completion of clinical 
laboratory tests and physical examination. They will return on Day 7 (±2) for follow-up procedures 
including physical examination, laboratory tests, and assessment of AEs and concomitant 
medication use. 
MAD 
On Day -1, eligible participants will be randomly assigned to active drug or placebo in a 10:2 ratio 
on a BID (q12h) or TID (q8h) schedule, to be determined based on the PK results of the SAD 
cohorts. Total daily doses will not exceed 2000 mg of ANA001. On Days 1 through 7, participants 
will receive their assigned treatment in the morning with a standardized light meal (500 to 750 cal) 
following an overnight fast of at least 10 hours. Afternoon or evening doses will be given with a 
light snack. A baseline ECG will be performed at Screening and at 3 hours after the second dose 
on Day 7. Blood pressure and heart rate will be measured every 8 hours while confined to the 
clinic.  
During BID dosing, blood for PK will be collected on Days 1 and 7 before dosing and at 0.5, 1, 2, 
4, 6, 8, 10, and 12 hours after dosing. Blood samples will also be collected on Days 2, 4, 6, and 8 
before dosing and before the 12 hour dose on Days 2, 4, and 6.  
During TID dosing, blood for PK will be collected on Days 1 and 7 before dosing and at 0.5, 1, 2, 
4, 6, and 8 hours after dosing. Blood samples will also be collected on Days 2, 4, 6, and 8 before 
dosing, and before the 8 hour dose on Days 2, 4, and 6, and before the 16 hour dose on Day 6. 
Participants will be discharged on Day 8 following the last PK sample and completion of clinical 
laboratory tests and physical examination. They will return on Day 15 (±2) for follow-up 
procedures including physical examination, laboratory tests, and assessment of AEs and 
concomitant medication use. 
Number of Participants: 
A minimum of 30 participants will be enrolled in the SAD part and up to 36 participants in the 
MAD part. At least 3 participants of each sex will be included in each cohort. 
Treatment Groups and Duration:

Investigational Product, Dose, and Mode of Administration 
ANA001 capsule containing 250 mg niclosamide, administered orally as 4, 6, 8 or 12 capsules 
with a light meal (500 to 750 cal) or snack. 
Statistical Methods 
Sample Size Determination: 
Sample size was not based on statistical considerations. 
Safety Analysis: 
All participants who received at least one dose of study drug will be included in the safety analysis. 
Safety will be assessed by the incidence and frequency of AEs, and changes in physical 
examinations, vital signs, clinical laboratory tests, and ECGs. Results will be summarized using 
descriptive statistics (mean, standard deviation [SD], coefficient of variation [%CV], median, 
minimum, maximum). 
Pharmacokinetic Analysis: 
All participants on active treatment who contributed at least one post dose blood sample, evaluable 
for drug PK concentration will be included in the PK analysis. PK parameters, calculated using 
non-compartmental models, include AUC0-∞, AUC0-t, AUC0-last, Cmax, tmax, t1/2, CL/F, and Vz/F. 
Results will be summarized using descriptive statistics (mean, standard deviation [SD], coefficient 
of variation [%CV], median, minimum, maximum). Plasma concentration-time profiles will be 
plotted.

Introduction 
Niclosamide is a chlorinated salicylanilide with anthelmintic, antiviral and anti-inflammatory 
activity being developed as a potential treatment for COVID-19. Niclosamide was discovered in 
1958, and was approved by the Food and Drug Administration (FDA) in 1982 under New Drug 
Application (NDA) 018669 (Bayer Pharmaceuticals) for the treatment of tapeworm infections, 
although it has since been voluntarily discontinued from marketing in the United States by Bayer. 
Niclosamide is approved in several other countries for the treatment of tapeworm infections and is 
on the World Health Organization's List of Essential Medicines. Due to its pleiotropic 
pharmacologic activity, niclosamide has been and continues to be studied for a variety of other 
clinical indications.  
ANA Therapeutics is developing ANA001, an orally administered niclosamide formulation 
containing 250 mg niclosamide per capsule, to treat adult patients with coronavirus disease of 2019 
(COVID-19). COVID-19 results in a cytokine release syndrome (Hirano and Murakami, 2020) 
that is associated – amongst others - with acute respiratory distress syndrome (ARDS), a 
widespread inflammation in the lungs, and increased blood clotting. Niclosamide is a promising 
oral therapeutic which has both antiviral and anti-inflammatory properties and a long history of 
safety in humans.   
Niclosamide has broad in vitro antiviral activity (Fan et al., 2019, Andersen et al., 2019, Jurgeit et 
al., 2012, Mazzon et al., 2019, Xu et al., 2020, Wu et al., 2004, Wen et al., 2007, Gassen et al., 
2019) including activity against severe acute respiratory syndrome coronavirus 2 (SARSCoV-2) 
with a half-maximal inhibitory concentration (IC50) of 0.15-0.28 µM (49-92 ng/mL) (Shi, 2020, 
unpublished data, Jeon et al., 2020, Gassen et al., 2020). Additionally, niclosamide has in vitro 
anti-inflammatory properties due to its inhibition of nuclear factor kappa-light-chain enhancer of 
activated B cells (NF-κB) and signal transducer and activator of transcription 3 (STAT3), two 
main drivers to induce the expression of proinflammatory cytokines. NF-κB and STAT3 were 
inhibited by niclosamide with an IC50 of 0.125 µM (40.9 ng/mL) (Jin et al., 2010) and 0.25 µM 
(81.8 ng/mL), respectively (Ren et al., 2010). In addition, a recent in vitro study showed that 
niclosamide works as a potent bronchodilator that relaxed histamine induced constriction of mouse 
tracheal rings and human bronchial rings with a half-maximal effective concentration (EC50) of 
124 ng/mL (0.4 µM) and 240 ng/mL (0.7 µM), respectively (Miner et al., 2019). 
PK data available in the literature show significant variability. A single dose of 2000 mg reaches 
maximal systemic serum concentrations in humans of 0.76 μM to 18.3 μM (249 to 5986 ng/mL) 
(Andrews et al., 1982). A study with prostate cancer patients showed that 149-182 ng/mL (0.46-
0.56 µM) become available after a single oral dose of 1000 mg (Schweizer et al., 2018). These 
studies strongly suggest that the dose regimen foreseen for clinical development – between 1000 
mg BID, 1000 mg TID and 2000 mg BID - will provide sufficient systemic and intracellular drug 
levels for effective antiviral and anti-inflammatory activity. However, there is a need for well 
characterized PK data to support dose selection in COVID-19 and other indications.

As niclosamide was approved by FDA to treat tapeworms in humans, it has a well-understood 
clinical safety profile on oral administration at 2000 mg daily for up to 7 days. In addition, it has 
been studied in clinical trials in oncology and several other indications, and two other Sponsors 
have recently initiated trials of niclosamide in COVID-19 patients. This Investigational New Drug 
Application represents the first clinical use of ANA001 capsules, thus there is no previous clinical 
data to report for this formulation of niclosamide. 
3.1. 
Study Rationale 
ANA001 is a new formulation containing 250 mg niclosamide per capsule. Although other 
niclosamide formulations have been studied for tapeworm infections and other potential human 
uses, limited systemic PK/PD data exists in the literature. To ensure proper systemic levels of 
niclosamide are achieved for therapeutic effect, a SAD/MAD study with ANA001 capsules is 
necessary. 
3.2. 
Background 
Niclosamide has broad in vitro antiviral activity (Fan et al., 2019, Andersen et al., 2019, Jurgeit et 
al., 2012, Mazzon et al., 2019, Xu et al., 2020, Wu et al., 2004, Wen et al., 2007, Gassen et al., 
2019) including activity against coronaviruses (Figure 1). Three initial publications have 
demonstrated that niclosamide inhibited replication of both SARS-CoV at concentrations of 
≥1.56 µM (≥510 ng/mL) (Wu et al., 2004) and 40 µM (13,084 ng/mL) (Wen et al., 2007) and 
Middle East respiratory syndrome (MERS)-CoV with an IC50 of 0.32 µM (105 ng/mL) (Gassen et 
al., 2019).

SARS-CoV, MERS-CoV and SARS-CoV-2 share 86% homology (Wilder-Smith et al., 2020) and 
three recent studies have confirmed the in vitro antiviral efficacy of niclosamide against 
SARSCoV-2. The reported IC50 values were 0.15 µM (49 ng/mL) (Shi, 2020, unpublished data), 
0.28 µM (92 ng/mL) (Jeon et al., 2020) and 0.17 µM (56 ng/mL) (Gassen et al., 2020). 
Furthermore, it was shown that pretreating cells for 24 h with 5 µM (1636 ng/mL) niclosamide 
followed by drug washout and viral infection reduced SARS-CoV-2 replication significantly 
(Gassen et al., 2020). This indicates that niclosamide has potential as a prophylactic COVID-19 
treatment and that serum concentrations may not need to continuously exceed in vitro inhibitory 
levels to be effective.

Nonclinical Studies 
Nonclinical Pharmacology 
In an in vitro study, Vero E6 cells were infected with a SARS-CoV-2 reporter virus. This virus has 
a luciferase gene engineered into its genome and when cells are infected with such a reporter virus, 
they express luciferase that can be quantified to measure viral replication. Increasing 
concentrations of niclosamide were added to Vero E6 cells together with reporter SARS-CoV-2. 
Twenty-four hours post-infection, infected cells were assayed for luciferase activity. The antiviral 
IC50 of niclosamide was 0.15 µM (49 ng/mL) (Shi, 2020, unpublished data). 
In a separate in vitro study, 50 FDA-approved drugs were screened for their ability to inhibit 
SARS-CoV-2 replication. Vero cells were infected with SARS-CoV-2 in the absence and presence 
of various drug concentrations. 24 hours post infection, cells were scored by immunofluorescence 
analysis with an antibody specific for the viral N protein of SARS-CoV-2 to generate dose-
response curves for each compound tested. Niclosamide demonstrated an IC50 of 0.28 µM 
(92 ng/mL). In the same assay, the IC50 values of remdesivir, chloroquine and lopinavir were 
11.41 µM (3732 ng/mL), 7.28 µM (2381 ng/mL) and 9.12 µM (2983 ng/mL), respectively (Jeon 
et al., 2020).  
In an additional in vitro study, VeroFM cells were infected with SARS-CoV-2 and treated with 
increasing concentrations of niclosamide. 48 hours post infection, plaque forming units were 
determined by plaque assay. The antiviral IC50 of niclosamide was 0.17 µM (56 ng/mL).

Furthermore, pretreating VeroFM cells for 24 h with 5 µM niclosamide significantly reduced viral 
replication (Gassen et al., 2020). 
Nonclinical Toxicology 
Oral toxicology studies for NDA 018669 evaluated niclosamide in mice, rats, rabbits, dogs, and 
cats. Single dose studies included doses as high as 5000 mg/kg in rats without any lethality 
(reviewed in Andrews et al., 1982). A repeat dose study with dogs showed that single oral doses 
of 6000 mg/kg for 8 consecutive days, followed by 4500 mg/kg for another 24 consecutive days 
were tolerated well with no signs of intoxication (reviewed in Andrews et al., 1982). Other repeat 
dose studies in rabbits, cats or dogs with doses that were 2-5 times the human therapeutic dose and 
lasted 11, 12, and 84-96 days were non toxic, based on routine laboratory tests and toxicology. 
Male cats were noted to have a mild reduction in white blood cells (WBC), and dogs showed a 
tendency toward watery stools, but otherwise adverse treatment effects were not evident. Other 
studies reported that doses of 250 mg/kg may cause vomiting in dogs and cats. The conclusion of 
these studies was that niclosamide was a low risk for dosing orally in humans at the standard 
therapeutic regimen of 2000 mg/day (BAYER NDA 018669; Summary Basis for Approval 
(SBA)). 
3.2.3. 
Safety 
Between 1971 and 1978, niclosamide was administered to 6365 patients under a US IND. Doses 
were up to and including 2000 mg/day for 7 days. There were 2385 evaluable patients, of which 
13.3% reported side effects, all of which were mild or moderate, with none requiring treatment 
discontinuation. These included nausea/emesis in 4.1%, abdominal discomfort/loss of appetite in 
3.4%, diarrhea in 1.6%, drowsiness/dizziness/headache in 1.4%, and skin rash/pruritis in 0.3% of 
patients (NDA 018669 Review Documentation).  
In addition, according to the Safety Review of Niclosamide, Pyrantel, Triclabendazole and 
Oxamniquine report of the World Health Organization (WHO), there have been 84 reported 
adverse drug reactions related to niclosamide between 1975 and 2004 in the WHO database. They 
include 173 reports from 16 countries and the most common reactions are related to skin and 
appendages (41 reports), gastrointestinal tract (37 reports), cardiovascular system (28 reports) and 
anaphylactic reactions (9 reports). 
Niclosamide was approved as a pregnancy class B drug and is thus safe to use during pregnancy. 
Summarized below are safety assessment findings reported in the available literature:  
• Prostate cancer patients received 500 mg and 1000 mg of niclosamide orally thrice per day 
for 15 days. TID regimens of >500 mg PO per day suggested the potential for DLT, 
however these findings are confounded by coadministration of antineoplastic treatment 
associated with a similar range of GI disturbances and occurred after niclosamide was 
dosed for >7 days (Schweizer et al., 2018). 
• Colorectal cancer patients received 2000 mg of niclosamide orally once per day until 
disease progression or toxicity (up to four months). No adverse side effects were reported 
(Burock et al., 2020).

• 2000 mg niclosamide/person did not result in hematological changes (Andrews et al., 
1982). 
• No induction of methemoglobinemia was observed in men after oral administration of 30 
mg/kg b.w. (~2000 mg/person) (Andrews et al., 1982). 
• Men and women received 1000 mg niclosamide once or twice per person; children (6-15 
years of age) received 750-1000 mg/person; neither scenario resulted in signs of 
intoxication (Andrews et al., 1982). 
• In a Phase I study, adults were divided into two groups (niclosamide and placebo). Study 
participants received 2000 mg/day for 3 days with a repeat course 6 days later. Transitory 
reactions, such as loose stools and stomach aches were reported (Andrews et al., 1982). 
• No dermal sensitizing effect was observed upon topical administration (Andrews et al., 
1982). 
At the established doses, most adverse events were transitory and generally mild to moderate.  
3.3. 
Benefit/Risk Assessment 
Niclosamide is approved for dosing up to 2000 mg PO daily for 7 days. There is limited safety and 
PK data in humans receiving more than 2000 mg as a single dose and/or more frequently than once 
daily. The current SAD/MAD study is designed to explore the safety and PK of dosing up to 3000 
mg/day as a single dose and regimens not to exceed 2000 mg/day as divided doses BID or TID. In 
light of the immediate pressing need for development of an effective and safe oral therapeutic that 
can prevent progression of COVID-19, the benefit to risk ratio for the study is anticipated to be 
justified. 
More detailed information about the known and expected benefits and risks and reasonably 
expected adverse events of ANA001 may be found in the Investigator’s Brochure.

Study Design 
5.1. 
Overall Design 
This is a randomized, double-blind study to be conducted in two parts: single ascending dose 
(SAD) and multiple ascending dose (MAD). Potential participants for each part will undergo 
screening procedures within 30 days of enrolment.  
SAD 
On Day -1, eligible participants will be randomly assigned to active drug or placebo in an 8:2 ratio. 
On Day 1, following an overnight fast of at least 10 hours, participants will receive their assigned 
treatment (1000 mg, 2000 mg, or 3000 mg of ANA001) with a standardized light meal (500 to 
750 cal).  A baseline ECG will be performed at Screening and at 3 hours after dosing. Blood 
pressure and heart rate will be measured every 8 hours while confined to the clinic. Blood for PK 
will be collected before dosing and at 0.5, 1, 2, 4, 6, 8, 10, 12 and 24 hours after dosing. Participants 
will be discharged on Day 2 following the 24-hour PK sample and completion of clinical 
laboratory tests and physical examination. They will return on Day 7 (±2) for follow-up procedures 
including physical examination, laboratory tests, and assessment of AEs and concomitant 
medication use. 
MAD 
On Day -1, eligible participants will be randomly assigned to active drug or placebo in a 9:3 ratio 
on a BID (q12h) or TID (q8h) schedule, to be determined based on the PK results of the SAD 
cohorts. Total daily doses will not exceed 2000 mg of ANA001. On Days 1 through 7, participants 
will receive their assigned treatment in the morning with a standardized light meal (500 to 750 cal) 
following an overnight fast of at least 10 hours. Afternoon or evening doses will be given with a 
light snack.  A baseline ECG will be performed at Screening and at 3 hours after the second dose 
on Day 7. Blood pressure and heart rate will be measured every 8 hours while confined to the 
clinic.  
During BID dosing, blood for PK will be collected on Days 1 and 7 before dosing  and at 0.5, 1, 
2, 4, 6, 8, 10, and 12 hours after dosing. Blood samples will also be collected on Days 2, 4, 6, and 
8 before dosing and before the 12 hour dose on Days 2, 4, and 6.  
During TID dosing, blood for PK will be collected on Days 1 and 7 before dosing and at 0.5, 1, 2, 
4, 6, and 8 hours after dosing. Blood samples will also be collected on Days 2, 4, 6, and 8 before 
dosing, before the 8 hour dose on Days 2, 4, and 6, and before the 16 hour dose on Day 6. 
Participants will be discharged on Day 8 following the last PK sample and completion of clinical 
laboratory tests and physical examination. They will return on Day 15 (±2) for follow-up 
procedures including physical examination, laboratory tests, and assessment of AEs and 
concomitant medication use.

5.2. 
Participant and Study Completion 
A minimum of 30 participants will be enrolled in the SAD part and up to 36 participants in the 
MAD part. At least 3 participants of each sex will be included in each cohort. 
5.3. 
End of Study Definition 
A participant is considered to have completed the study if he/she has completed all phases of the 
study including the last scheduled procedure shown in the Schedule of Activities. 
The end of the study is defined as the date of the last visit of the last participant in the study. 
5.4. 
Scientific Rationale for Study Design 
Sequential timing of the ascending dose cohorts will allow early stopping if serious or 
unanticipated safety signals are observed at any dose level. 
5.5. 
Justification for Dose 
Niclosamide was approved by FDA to treat tapeworms in humans and has a well understood 
clinical safety profile with oral administration at 2000 mg daily for up to 7 days. Furthermore, a 
single dose of 2000 mg reaches maximal systemic serum concentrations in humans of 0.76 μM to 
18.3 μM (249 ng/mL to 5986 ng/mL) (Andrews et al., 1982). A study with prostate cancer patients 
showed that 149 ng/mL to 182 ng/mL (0.46 µM to 0.56 µM) become available after a single oral 
dose of 1000 mg (Schweizer et al., 2018). In a very recent study, colorectal cancer patients received 
2000 mg of niclosamide orally once a day until disease progression or toxicity (up to four months). 
Plasma levels mainly peaked 240 minutes after the first niclosamide administration with a median 
Cmax of 2.03 µM (665 ng/mL) (Burock et al., 2020). The lower bounds of the reported Cmax values 
fall within the effective in vitro ranges of niclosamide as an antiviral agent (0.15-0.28 µM, 49-92 
ng/mL) (Shi, 2020, unpublished results; Jeon et al., 2020, Gassen et al., 2020) and an anti-
inflammatory drug that inhibits NF-kB and STAT3 at 0.13 µM (42.5 ng/mL) (Jin et al., 2010) and 
0.25 µM (81.8 ng/mL) (Ren et al., 2010), respectively. 
These studies strongly suggest that the dose regimens between 1000 mg BID to 2000 mg BID or 
1000 mg TID to 1500 mg TID will provide sufficient systemic and intracellular drug levels for 
effective antiviral and anti-inflammatory activity. The current study is designed to assess the safety 
of single doses of niclosamide up to 3000 mg and multiple dosing regimens not to exceed 2000 
mg daily divided BID or TID. The PK data from this study will be used to refine the optimum dose 
and frequency of administration to achieve antiviral and anti-inflammatory activity in humans.

Discontinuation/Withdrawal Criteria  
8.1. 
Discontinuation of Study Treatment  
An unexpected AE related to study drug could lead to temporary or permanent discontinuation of 
a participant’s study treatment, as determined by the Medical Monitor or Investigator.   
8.2. 
Withdrawal from the Study 
A participant 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. 
If the participant 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 participant 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. 
See SoA (Section 2) for data to be collected at the time of study discontinuation and follow-up 
and for any further evaluations that need to be completed. 
Participants who withdraw will not be replaced. 
8.3. 
Lost to Follow Up 
A participant will be considered lost to follow-up if he or she repeatedly fails to return for 
scheduled visits and is unable to be contacted by the study site.  
The following actions must be taken if a participant fails to return to the clinic for a required 
study visit: 
• The site must attempt to contact the participant and reschedule the missed visit as soon as 
possible and counsel the participant on the importance of maintaining the assigned visit 
schedule and ascertain whether or not the participant wishes to and/or should continue in 
the study. 
• Before a participant is deemed lost to follow up, the Investigator or designee must make 
every effort to regain contact with the participant (where possible, 3 telephone calls and, 
if necessary, a certified letter to the participant’s last known mailing address or local 
equivalent methods). These contact attempts should be documented in the participant’s 
medical record. 
• Should the participant continue to be unreachable, he/she will be considered to have 
withdrawn from the study with a primary reason of lost to follow-up.

Study Assessments and Procedures 
• Study procedures and their timing are summarized in the SoA. Protocol waivers or 
exemptions are not allowed. 
• Immediate safety concerns should be discussed with the Sponsor immediately upon 
occurrence or awareness to determine if the participant should continue or discontinue study 
treatment. 
• Adherence to the study design requirements, including those specified in the SoA, is essential 
and required for study conduct. 
• All screening evaluations must be completed and reviewed to confirm that potential 
participants meet all eligibility criteria. The Investigator will maintain a screening log to 
record details of all participants screened and to confirm eligibility or record reasons for 
screening failure, as applicable.  
• Procedures conducted as part of the participant’s routine clinical management (e.g., blood 
count) and obtained before signing of the ICF may be utilized for screening or baseline 
purposes provided the procedures met the protocol-specified criteria and were performed 
within the time frame defined in the SoA.

9.1.2. 
Vital Signs 
Vital signs should be taken in a quiet setting without distractions (e.g., television, cell phones) 
and before any blood collections. 
Oral temperature, pulse rate, respiratory rate, and blood pressure will be assessed. 
Blood pressure and pulse measurements will be assessed with a completely automated device 
after 3 to 5 minutes rest in a supine position. Manual techniques will be used only if an 
automated device is not available. 
Blood pressure and pulse measurements will be measured after 3 to 5 minutes rest in a supine 
position. 
9.1.3. 
Electrocardiograms 
A single ECG will be obtained for screening and at 3 hours after dosing during the SAD portion 
of the study and at Screening and 3 hours after dosing on Day 7 during the MAD portion. An ECG 
machine that automatically calculates the heart rate and measures PR, QRS, QT, and QTc intervals 
will be used. 
9.1.4. 
Clinical Safety Laboratory Assessments 
See Appendix 2 for the list of clinical laboratory tests to be performed and the SoA (Section 2) for 
the timing and frequency.  
The Investigator must review the laboratory report, document this review, and record any clinically 
relevant changes (as per the reference laboratory values [Appendix 6]) occurring during the study 
in the AE section of the CRF. The laboratory reports must be filed with the source documents. 
Clinically significant abnormal laboratory findings are those which are not associated with the 
underlying disease, unless judged by the Investigator to be more severe than expected for the 
participant's condition. 
All laboratory tests with values considered clinically significantly abnormal during participation 
in the study should be repeated until the values return to normal or baseline or are no longer 
considered clinically significant as per the reference laboratory values in Appendix 6. 
• If such values do not return to normal/baseline within a period of time judged reasonable 
by the Investigator, the etiology should be identified and the Sponsor notified. 
• All protocol-required laboratory assessments, as defined in Appendix 2, must be 
conducted in accordance with the laboratory manual and the SoA.  
• If laboratory values from non-protocol specified laboratory assessments performed at the 
institution’s local laboratory require a change in participant management or are considered 
clinically significant as given in Appendix 6 (e.g., SAE or AE or dose modification), then 
the results must be recorded in the CRF.

Adverse Events 
The definitions of an AE or SAE can be found in Appendix 4. 
AE will be reported by the participant (or, when appropriate, by a caregiver, surrogate, or the 
participant's legally authorized representative).  
The Investigator and any 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 treatment or study procedures, or that caused the 
participant to discontinue the study.  
9.2.1. 
Time Period and Frequency for Collecting AE and SAE Information  
All AEs and SAEs will be collected from the signing of the ICF until the follow-up visit at the 
time points specified in the SoA (Section 2). 
Medical occurrences that begin before the start of study treatment but after obtaining informed 
consent will be recorded on the Medical History/Current Medical Conditions section of the case 
report form (CRF) not the AE section. 
All SAEs will be recorded and reported to the Sponsor or designee within 24 hours, as indicated 
in Appendix 4. 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 AEs or SAEs in former study participants. However, 
if the Investigator learns of any SAE, including a death, at any time after a participant has been 
discharged from the study, and he/she considers the event to be reasonably related to the study 
treatment or study participation, the Investigator must promptly notify the Sponsor. 
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 4. 
9.2.2. 
Method of Detecting AEs and SAEs 
Care will be taken not to introduce bias when detecting AEs and/or SAEs. Open-ended and 
non-leading verbal questioning of the participant is the preferred method to inquire about 
AE occurrences.  
9.2.3. 
Follow-up of AEs and SAEs 
After the initial AE/SAE report, the Investigator is required to proactively follow each participant 
at subsequent visits/contacts. All SAEs will be followed until resolution, stabilization, the event is 
otherwise explained, or the participant is lost to follow-up (as defined in Section 8.3). Further 
information on follow-up procedures is given in Appendix 4.

9.2.4. 
Regulatory Reporting Requirements for SAEs 
Prompt notification by the Investigator to the Sponsor of an SAE is essential so that legal 
obligations and ethical responsibilities towards the safety of participants and the safety of a study 
treatment under clinical investigation are met.  
The Sponsor has a legal responsibility to notify both the local regulatory authority and other 
regulatory agencies about the safety of a study treatment under clinical investigation. The Sponsor 
will comply with country-specific regulatory requirements relating to safety reporting to the 
regulatory authority, Institutional Review Boards (IRB)/Independent Ethics Committees (IEC), 
and Investigators. 
Investigator safety reports must be prepared for suspected unexpected serious adverse reactions 
(SUSAR) 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. 
9.2.5. 
Pregnancy 
Details of all pregnancies in female participants and, if indicated, female partners of male 
participants will be collected after the start of study treatment and until 30 days after the last dose. 
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 5. 
Abnormal pregnancy outcomes (e.g., spontaneous abortion, fetal death, stillbirth, congenital 
anomalies, ectopic pregnancy) are considered SAEs. 
9.3. 
Stopping Rules in Response to SAEs or Other Events 
Dose-limiting toxicity AEs will be defined as Grade ≥3, treatment-emergent, treatment-related 
laboratory abnormalities (Appendix 6) or AEs per the grading system by US Department of 
Health and Human Services (CTCAE, Version 5.0)The following Stopping Criteria will be used: 
Clinical Findings: 
1. Anaphylaxis or Grade ≥3 skin rash or pruritis 
2. Grade ≥3 nausea, emesis or diarrhea 

CONFIDENTIAL 
 
ANA Therapeutics 
Protocol ANA001 
Page 40 of 69 
 
Status: Final v2.0; Date 09Jan2021 
 
Laboratory Findings: 
1. Evidence of new onset of acute renal or hepatic failure, defined by increases in 
BUN, creatinine, or LFTs (AST, ALT, Alkaline phosphatase) that reflect new 
evidence of Grade 3 thresholds for liver function tests, for creatinine, and for 
electrolytes attributable to the administration of drug in the context of the 
Investigator’s evaluation.  
2. Evidence of acute infection or inflammation, defined by changes in the WBC and 
differential, attributable to the administration of drug in the context of the 
Investigator’s evaluation.  
3. Any “unexpected” Grade ≥3 laboratory test result.  
If one of the above clinical or laboratory criteria for stopping occurs in any subject, further 
study recruitment and subject dosing will be halted until a full safety assessment can be 
completed. Unblinding of the affected subject will be performed and the PI and Sponsor will 
review the totality of clinical data and any other circumstances possibly related to the “Stopping 
Criteria” findings to determine if the study can be resumed, modified, or will be permanently 
terminated.  
9.4. 
Treatment of Overdose 
For this study, any dose of ANA001 greater than 3000 mg within a 24-hour time period will be 
considered an overdose. 
In the event of an overdose, the Investigator should: 
1. Contact the Medical Monitor immediately. 
2. Closely monitor the participant for any AE/SAE and laboratory abnormalities until 
ANA001 can no longer be detected systemically (at least 7 days). 
3. Document the quantity of the excess dose as well as the duration of the overdose in the 
CRF. 
Decisions regarding dose interruptions or modifications will be made by the Investigator in 
consultation with the Medical Monitor based on the clinical evaluation of the participant. 
9.5. 
Pharmacokinetics 
Whole blood samples of approximately 4 mL will be collected for measurement of plasma 
concentrations of ANA001 as specified in the SoA (Section 2). Additional samples may be 
collected during the study if warranted and agreed upon between the Investigator and the Sponsor.

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. 
Any changes in the timing or addition of time points for any planned study assessments must be 
documented and approved by the relevant study team member and then archived in the Sponsor 
and site study files, but will not constitute a protocol amendment. The IRB/IEC will be informed

Statistical Considerations  
10.1. 
Sample Size Determination  
Sample size was not based on statistical considerations. 
10.2. 
Populations for Analyses 
For purposes of analysis, the following populations are defined: 
Population 
Description 
Enrolled  
All participants who sign the ICF 
Safety 
All participants randomly assigned to study treatment and who 
take at least 1 dose of study treatment. Participants will be 
analyzed according to the treatment they actually received. 
Pharmacokinetic 
All participants randomly assigned to study treatment, who take 
at least 1 dose of study treatment, and contribute at least 1 post-
dose evaluable PK sample. Participants will be analyzed 
according to the dose they actually received. 
10.3. 
Statistical Analyses 
The statistical analysis plan will be developed and finalized before database lock and will describe 
the participant populations to be included in the analyses, and procedures for accounting for 
missing, unused, and spurious data. This section is a summary of the planned statistical analyses 
of the primary and secondary endpoints. 
10.3.1. Safety Analyses 
All safety analyses will be performed on the Safety Population. Safety parameters will include 
frequency of treatment-emergent AEs (TEAEs), SAEs, study drug discontinuation due to an AE 
(MAD portion only), concomitant medication use, and changes from baseline in clinical laboratory 
results, vital signs, ECG, and physical examinations. TEAEs are defined as AEs that started or 
worsened after dosing. Adverse events will be coded using the latest version of the Medical 
Dictionary for Regulatory Activities. A list of participants who have SAEs and who discontinue 
from the study due to an AE will be provided. Treatment-emergent AEs will be summarized by 
system organ class and preferred term for each dose level. 
Individual results of laboratory tests (chemistry, hematology, and urinalysis) will be listed and 
summarized. Baseline, post-dose, and change from baseline to post-dose laboratory data will be 
summarized by dose. Individual results of vital signs will be listed and summarized. Observed 
values and changes from baseline in vital signs will be summarized by dose. Individual results of 
ECG parameters from the 12-lead safety ECGs will be listed and changes from baseline will be

summarized by dose. Physical examination findings and concomitant medication use will be 
presented in data listings.  
10.3.2. Pharmacokinetic Analyses  
The non-compartmental PK analyses will be described in the Statistical Analysis Plan finalized 
before database lock. Plasma concentrations of ANA001 will be summarized by dose over each 
scheduled sampling time using descriptive statistics. Individual plasma concentration data versus 
actual time points will be presented in listings. Pharmacokinetic parameters of ANA001 will be 
summarized by dose using descriptive statistics. Individual PK parameters will be presented in a 
data listing. Dose proportionality will be assessed graphically and using the power model. 
10.3.3. Interim Analyses  
Data from the SAD Cohorts S1 through S3 will be summarized and evaluated to determine the 
doses and schedule to be used in a potential 4th SAD cohort and the BID and TID MAD cohorts. 
The Statistical Analysis Plan will describe the planned interim analyses in greater detail.

Consideration will be given to any comments on a draft report. The report will incorporate the 
analytical and statistical results and methods produced by the Sponsor or their agents. A final 
report will be prepared to contain all those sections in the draft and a statement of compliance 
covering all the areas of the study conducted at the investigational site and the report, with GCP. 
The report will be issued under the Sponsor’s responsibility. 
Where required by the applicable regulatory requirements, an Investigator signatory will be 
identified for the approval of the clinical study report. The Investigator will be provided reasonable 
access to statistical tables, figures, and relevant reports and will have the opportunity to review 
complete study results. The Sponsor will also provide the Investigator with the full summary of 
study results. 
Data Quality Assurance 
All participant data relating to the study will be recorded on printed or electronic CRF unless 
transmitted to the Sponsor or designee electronically (e.g., laboratory data). The Investigator is 
responsible for verifying that data entries are accurate and correct by physically or electronically 
signing the CRF.  
The Investigator must maintain accurate documentation (source data) that supports the 
information entered in the CRF.  
The Investigator must permit study-related monitoring, audits, IRB/IEC review, and regulatory 
agency inspections and provide direct access to source data documents.  
The Sponsor or designee is responsible for the data management of this study including quality 
checking of the data.  
Study monitors will perform ongoing source data verification to confirm that data entered into 
the CRF by authorized site personnel are accurate, complete, and verifiable from source 
documents; that the safety and rights of participants are being protected; and that the study is 
being conducted in accordance with the currently approved protocol and any other study 
agreements, ICH GCP, and all applicable regulatory requirements.  
Records and documents, including signed ICFs, pertaining to the conduct of this study must be 
retained by the Investigator for 5 years after study completion unless local regulations or 
institutional policies require a longer retention period. No records may be destroyed during the 
retention period without the written approval of the Sponsor. No records may be transferred to 
another location or party without written notification to the Sponsor.

Source Documents 
Source documents provide evidence for the existence of the participant and substantiate the 
integrity of the data collected. Source documents are filed at the Investigator’s site. 
Data reported on the CRF or entered in the eCRF that are transcribed from source documents 
must be consistent with the source documents or the discrepancies must be explained. The 
Investigator may need to request previous medical records or transfer records, depending on the 
study. Also, current medical records must be available. 
Study and Site Closure 
The Sponsor 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: 
• 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 
• Inadequate recruitment of participants by the Investigator 
• Discontinuation of further study treatment development

Appendix 4: Adverse Events: Definitions and Procedures for Recording, 
Evaluating, Follow-up, and Reporting 
Definition of an Adverse Event (AE) 
AE Definition 
• 
An AE is any untoward medical occurrence in a patient or clinical study participant, 
temporally associated with the use of study treatment, whether or not considered 
related to the study treatment. 
• 
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 treatment. 
 
Events Meeting the AE Definition  
• 
Any abnormal laboratory test results (hematology, clinical chemistry, or urinalysis) 
or other safety assessments (e.g., ECG, radiological scans, vital signs 
measurements), including those that worsen from baseline, considered clinically 
significant by the Investigator per Appendix 6 (i.e., not related to progression of 
underlying disease). 
• 
Exacerbation of a chronic or intermittent pre-existing condition including either an 
increase in frequency and/or intensity of the condition. 
• 
New conditions detected or diagnosed after study treatment administration even 
though it may have been present before the start of the study. 
• 
Signs, symptoms, or the clinical sequelae of a suspected drug-drug interaction. 
• 
Signs, symptoms, or the clinical sequelae of a suspected overdose of either study 
treatment 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. 
 
Events NOT Meeting the AE Definition  
• 
Any clinically significant abnormal laboratory findings or other abnormal safety 
assessments which are associated with the underlying disease, unless judged by the 
Investigator to be more severe than expected for the participant’s condition. 

CONFIDENTIAL 
 
ANA Therapeutics 
Protocol ANA001 
Page 59 of 69 
 
Status: Final v2.0; Date 09Jan2021 
 
• 
The disease/disorder being studied or expected progression, signs, or symptoms of 
the disease/disorder being studied, unless more severe than expected for the 
participant’s condition. 
• 
Medical or surgical procedure (e.g., endoscopy, appendectomy): the condition that 
leads to the procedure is the AE. 
• 
Situations in which an untoward medical occurrence did not occur (social and/or 
convenience admission to a hospital). 
• 
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 
If an event is not an AE per definition above, 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). 
A 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 
participant 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 
In general, hospitalization signifies that the participant 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. 
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 

CONFIDENTIAL 
 
ANA Therapeutics 
Protocol ANA001 
Page 60 of 69 
 
Status: Final v2.0; Date 09Jan2021 
 
• 
The term disability means a substantial disruption of a person’s ability to conduct 
normal life functions. 
• 
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: 
• 
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 participant 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. 
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. 
Recording and AE and/or SAE 
AE and SAE Recording 
• 
When an AE/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. 
• 
The Investigator will then record all relevant AE/SAE information in the CRF. 
• 
It is not acceptable for the Investigator to send photocopies of the participant’s 
medical records to ANA Therapeutics in lieu of completion of the AE/SAE CRF 
page. 
• 
There may be instances when copies of medical records for certain cases are 
requested by ANA Therapeutics. In this case, all participant identifiers, with the 
exception of the participant number, will be redacted on the copies of the medical 
records before submission to ANA Therapeutics. 

CONFIDENTIAL 
 
ANA Therapeutics 
Protocol ANA001 
Page 61 of 69 
 
Status: Final v2.0; Date 09Jan2021 
 
• 
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/SAE. 
Assessment of Intensity 
The Investigator will make an assessment of intensity for each AE and SAE reported 
during the study and assign it to 1 of the following categories:  
• 
Mild: An event that is easily tolerated by the participant, causing minimal discomfort 
and not interfering with everyday activities. 
• 
Moderate: An event that causes sufficient discomfort and interferes with normal 
everyday activities. 
• 
Severe: An event that prevents normal everyday activities. An AE that is assessed as 
severe should not be confused with a SAE. Severe is a category utilized for rating the 
intensity of an event; and both AEs and SAEs can be assessed as severe. 
An event is defined as ‘serious’ when it meets at least 1 of the predefined outcomes 
as described in the definition of an SAE, NOT when it is rated as severe. 
 
Assessment of Causality 
• 
The Investigator is obligated to assess the relationship between study treatment and 
each occurrence of each AE/SAE. 
• 
A "reasonable possibility" of a relationship conveys that there are facts, evidence, 
and/or arguments to suggest a causal relationship, rather than a relationship cannot 
be ruled out. 
• 
The Investigator will use clinical judgment to determine the relationship. 
• 
Alternative causes, such as underlying disease(s), concomitant therapy, and other 
risk factors, as well as the temporal relationship of the event to study treatment 
administration will be considered and investigated. 
• 
The Investigator will also consult the Investigator’s Brochure (IB) and/or Product 
Information, for marketed products, in his/her assessment. 
• 
For each AE/SAE, the Investigator must document in the medical notes that he/she 
has reviewed the AE/SAE and has provided an assessment of causality. 

CONFIDENTIAL 
 
ANA Therapeutics 
Protocol ANA001 
Page 62 of 69 
 
Status: Final v2.0; Date 09Jan2021 
 
• 
There may be situations in which an SAE has occurred and the Investigator has 
minimal information to include in the initial report to ANA Therapeutics. 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 ANA 
Therapeutics. 
• 
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. 
• 
The causality assessment is one of the criteria used when determining regulatory 
reporting requirements. 
 
Follow-up of AEs and SAEs 
• 
The Investigator is obligated to perform or arrange for the conduct of supplemental 
measurements and/or evaluations as medically indicated or as requested by ANA 
Therapeutics 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. 
• 
If a participant dies during participation in the study or during a recognized follow-
up period, the Investigator will provide ANA Therapeutics with a copy of any post-
mortem findings including histopathology. 
• 
New or updated information will be recorded in the originally completed CRF. 
• 
The Investigator will submit any updated SAE data to the ANA Therapeutics within 
24 hours of receipt of the information. 
 
Reporting of SAEs 
SAE Reporting to ANA Therapeutics via an Electronic Data Collection Tool 
• 
The primary mechanism for reporting an SAE to ANA Therapeutics will be the 
electronic data collection tool. 
• 
If the electronic system is unavailable for more than 24 hours, then the site will use 
the paper SAE data collection tool (see next section). 
• 
The site will enter the SAE data into the electronic system as soon as it becomes 
available. 

CONFIDENTIAL 
 
ANA Therapeutics 
Protocol ANA001 
Page 63 of 69 
 
Status: Final v2.0; Date 09Jan2021 
 
• 
After the study is completed at a given site, the electronic data collection tool will be 
taken off-line to prevent the entry of new data or changes to existing data. 
• 
If a site receives a report of a new SAE from a study participant or receives updated 
data on a previously reported SAE after the electronic data collection tool has been 
taken off-line, then the site can report this information on a paper SAE form (see 
next section) or by telephone. 
• 
Contacts for SAE reporting can be found in the Study Manual. 
 
SAE Reporting via Paper CRF 
• 
Facsimile transmission of the SAE paper CRF is the preferred method to transmit 
this information to the SAE coordinator. 
• 
In rare circumstances and in the absence of facsimile equipment, notification by 
telephone is acceptable with a copy of the SAE data collection tool sent by overnight 
mail or courier service. 
• 
Initial notification via telephone does not replace the need for the Investigator to 
complete and sign the SAE CRF pages within the designated reporting time frames. 
• 
Contacts for SAE reporting can be found in the Study Manual.

Appendix 5: 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. Premenarchal 
2. Premenopausal female with 1 of the following: 
• Documented hysterectomy 
• Documented bilateral salpingectomy 
• Documented bilateral oophorectomy 
Note:  Documentation can come from the site personnel’s: review of the participant’s 
medical records, medical examination, or medical history interview. 
 
3. Postmenopausal female 
• A postmenopausal state is defined as no menses for 12 months without an alternative 
medical cause. A high follicle stimulating hormone (FSH) level in the 
postmenopausal range may be used to confirm a postmenopausal state in women not 
using hormonal contraception or hormonal replacement therapy (HRT). However, in 
the absence of 12 months of amenorrhea, a single FSH measurement is insufficient.  
• Females on HRT and whose menopausal status is in doubt will be required to use one 
of the non-hormonal highly effective contraception methods if they wish to continue 
their HRT during the study. Otherwise, they must discontinue HRT to allow 
confirmation of postmenopausal status before study enrollment. 
Contraception Guidance 
Male participants 
• Male participants with female partners of childbearing potential are eligible to 
participate if they agree to ONE of the following [during the protocol-defined time 
frame in Section 6.1]:  

CONFIDENTIAL 
 
ANA Therapeutics 
Protocol ANA001 
Page 65 of 69 
 
Status: Final v2.0; Date 09Jan2021 
 
Are abstinent from penile-vaginal intercourse as their usual and preferred lifestyle (abstinent on a 
long term and persistent basis) and agree to remain abstinent 
• Agree to use a male condom plus partner use of a contraceptive method with a failure 
rate of <1% per year as described in Table 5 when having penile-vaginal intercourse 
with a woman of childbearing potential who is not currently pregnant 
Men with a pregnant or breastfeeding partner must agree to remain abstinent from penile-vaginal 
intercourse or use a male condom during each episode of penile penetration [during the protocol-
defined time frame]  
Refrain from donating sperm for the duration of the study and for 30 days after the last dose of 
study treatment. 
Female participants 
Female participants of childbearing potential are eligible to participate if they agree to use a 
highly effective method of contraception consistently and correctly as described in Table 5. 
 
Table 5: 
 Highly Effective Contraceptive Methods 
Highly Effective Contraceptive Methods That Are User Dependent a  
Failure rate of <1% per year when used consistently and correctly.  
Combined (estrogen and progestogen containing) hormonal contraception associated with 
inhibition of ovulationb  
• Oral  
• Intravaginal  
• Transdermal  
Progestogen only hormonal contraception associated with inhibition of ovulation 
• Oral  
• Injectable  
Highly Effective Methods That Are User Independent a  
Implantable progestogen only hormonal contraception associated with inhibition of ovulationb 
• Intrauterine device (IUD) 
• Intrauterine hormone-releasing system (IUS) 
Bilateral tubal occlusion 
Vasectomized partner  
A vasectomized partner is a highly effective contraception method provided that the partner is 
the sole male sexual partner of the WOCBP and the absence of sperm has been confirmed. If 
not, an additional highly effective method of contraception should be used.  
Sexual abstinence  

CONFIDENTIAL 
 
ANA Therapeutics 
Protocol ANA001 
Page 66 of 69 
 
Status: Final v2.0; Date 09Jan2021 
 
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 treatment. 
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 participant.  
NOTES:  
a) Typical use failure rates may differ from those when used consistently and correctly. Use 
should be consistent with local regulations regarding the use of contraceptive methods for 
participants participating in clinical studies.  
b) Hormonal contraception may be susceptible to interaction with the study treatment, which 
may reduce the efficacy of the contraceptive method. In this case, two highly effective 
methods of contraception should be utilized during the treatment period and for at least 30 
days after the last dose of study treatment  
 
Pregnancy Testing 
• 
WOCBP should only be included after a confirmed menstrual period and a negative highly 
sensitive pregnancy test. 
• 
Pregnancy testing will be performed whenever a menstrual cycle is missed or when 
pregnancy is otherwise suspected  
Collection of Pregnancy Information  
Male participants with partners who become pregnant  
• 
The Investigator will attempt to collect pregnancy information on any male participant’s 
female partner who becomes pregnant while the male participant is in this study. This applies 
only to male participants who receive active study treatment. 
• 
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 Participants who become pregnant

• 
The Investigator will collect pregnancy information on any female participant who becomes 
pregnant while participating in this study. Information will be recorded on the appropriate 
form and submitted to the Sponsor within 24 hours of learning of a participant's pregnancy. 
The participant will be followed to determine the outcome of the pregnancy. The Investigator 
will collect follow-up information on the participant 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 will be reported as an AE or SAE. A spontaneous abortion 
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 treatment by the Investigator will be 
reported to the Investigator as described in Section 9.2. While the Investigator is not obligated 
to actively seek this information in former study participants, he or she may learn of an SAE 
through spontaneous reporting.  
• 
Any female participant who becomes pregnant while participating in the study will be 
withdrawn from the study
