• adverse events; 
• protocol violations; 
• administrative reasons (e.g., inability to continue due to scheduling 
changes); 
• lost to follow up; 
• sponsor termination of study; 
• subject choice (e.g. withdrawal of consent); and 
• other 
Note: In addition, any subject may be discontinued for any sound medical 
reason at the discretion of the investigator. 
Notification of a subject discontinuation and the reason for discontinuation 
will be made to Ora and/or study sponsor and will be clearly documented 
on the eCRF. 
8.7 Study Termination 
The study may be stopped at any time by the investigator, the sponsor, and/or Ora 
with appropriate notification. 
8.8 Study Duration 
An individual subject’s participation will involve 5 visits over approximately a 9-

carried out giving consideration to data protection as well as subject confidentiality to 
the extent that local, state, and federal laws apply. 
9 ADVERSE EVENTS 
9.1 Adverse Event 
An adverse event is defined as any untoward medical occurrence associated with the 
use of a drug in humans, whether or not the event is considered drug-related.  An 
adverse event can therefore be any unfavorable and unintended sign (e.g., an 
abnormal laboratory finding), symptom, or disease occurring after the subject started 
dosing with the study drug, without any judgment about causality.  Any pre-existing 
medical condition that worsens after administration of the study drug will also be 
considered a new adverse event.   
If there is a worsening of a medical condition that was present prior to the 
administration of the study drug, this should also be considered a new adverse event 
and reported.  Any medical condition present prior to the administration of the study 
drug that remains unchanged or improved should not be recorded as a treatment 
emergent adverse event at subsequent visits unless it worsens during treatment. 
Study drug includes the investigational drug under evaluation and any comparator 
drug, placebo, or any other medications required by the protocol given during any 
stage of the study. 
Documentation regarding the adverse event should be made as to the nature, date of 
onset, end date, severity, relationship to study drug, action(s) taken, seriousness, and 
outcome of any sign or symptom observed by the physician or reported by the patient 
upon indirect questioning.  
9.1.1 Severity 
Severity of an adverse event is defined as a qualitative assessment of the 
degree of intensity of an adverse event as determined by the investigator 
or reported to him/her by the patient/subject.  The assessment of severity 
is made irrespective of relationship to study drug or seriousness of the 
event and should be evaluated according to the following scale: 
• Mild: Event is noticeable to the subject, but is easily tolerated and 
does not interfere with the subject’s daily activities. 
• Moderate: Event is bothersome, possibly requiring additional 
therapy, and may interfere with the subject’s daily activities. 
• Severe: Event is intolerable, necessitates additional therapy or 
alteration of therapy, and interferes with the subject’s daily 
activities.

Page 38 of 76 
9.1.2 Relationship to Study Drug 
The relationship of each adverse event to the study drug should be 
determined by the investigator using these explanations: 
• Definite: When there are good reason and sufficient documentation 
to demonstrate a direct causal relationship between investigational 
product and AE; 
• Probable: When there are good reasons and sufficient 
documentation to assume a causal relationship in the sense of 
plausible, conceivable, likely but not necessarily highly probable. 
• Possible: When there is sufficient information to accept the 
possibility of a causal relationship in the sense of not impossible 
and not unlikely, although the connection is uncertain or doubtful, 
for example, due to missing data or insufficient evidence. 
None: When there is sufficient information to accept a lack of a 
causal relationship, in the sense of impossible and improbable. 
• Unclassified: When the causal relationship is not assessable for 
whatever reason due to insufficient evidence, conflicting data or 
poor documentation. 
Suspected adverse reaction means any adverse event for which there is a 
reasonable possibility that the study drug caused the adverse event.  
“Reasonable possibility” means there is evidence to suggest a causal 
relationship between the study drug and the adverse event.  Types of 
evidence that would suggest a causal relationship between the study drug 
and the adverse event include: a single occurrence of an event that is 
uncommon and known to be strongly associated with drug exposure (e.g., 
angioedema, hepatic injury, Stevens-Johnson Syndrome); one or more 
occurrences of an event that is not commonly associated with drug 
exposure, but is otherwise uncommon in the population exposed to the 
drug (e.g., tendon rupture); an aggregate analysis of specific events 
observed in a clinical trial (such as known consequences of the underlying 
disease or condition under investigation or other events that commonly 
occur in the study population independent of drug therapy) that indicates 
those events occur more frequently in the drug treatment group than in a 
concurrent or historical control group. 
9.1.3 Expectedness 
The expectedness of an adverse event should be determined based upon 
existing safety information about the study drug using these explanations: 
• Unexpected: An adverse event that is not listed in the 
Investigator’s brochure or is not listed at the specificity or severity 
that has been observed. 
• Expected: An adverse event that is listed in the Investigator’s 
brochure at the specificity and severity that has been observed.

Clinical Trial Protocol: VISTA-1 / 18-110-0004 
Final V 1.0 13Sep2018 
Confidential 
Page 39 of 76 
• Not Applicable: Any adverse event that is unrelated to the study 
drug. 
Adverse events that are mentioned in the Investigator’s brochure as 
occurring with a class of drugs or as anticipated from the pharmacological 
properties of the drug, but are not specifically mentioned as occurring with 
the particular drug under investigation are to be considered unexpected. 
The investigator should initially classify the expectedness of an adverse 
event, but the final classification is subject to the Medical Monitor’s 
determination. 
9.2 Serious Adverse Events 
An adverse event is considered serious if, in the view of either the investigator or 
sponsor, it results in any of the following outcomes: 
• Death; 
• A life-threatening adverse event; 
Note:  An adverse event is considered “life-threatening” if, in the view of 
either the investigator or sponsor, its occurrence places the patient or subject 
at immediate risk of death.  It does not include an adverse event that, had it 
occurred in a more severe form, might have caused death. 
• Inpatient hospitalization or prolongation of existing hospitalization; 
Note:  The term “inpatient hospitalization” refers to any inpatient admission 
(even if less than 24 hours).  For chronic or long-term inpatients, inpatient 
admission includes transfer within the hospital to an acute/intensive care 
inpatient unit.  Inpatient hospitalization does not include:  emergency room 
visits; outpatient/same-day/ambulatory procedures; observation/short stay 
units; rehabilitation facilities; hospice facilities; nursing homes; or clinical 
research/phase 1 units. 
Note:  The term “prolongation of existing hospitalization” refers to any 
extension of an inpatient hospitalization beyond the stay anticipated or 
required for the reason for the initial admission as determined by the 
investigator or treating physician. 
• A persistent or significant incapacity or substantial disruption of the ability to 
conduct normal life functions; 
Note:  A serious adverse event specifically related to visual threat would be 
interpreted as any potential impairment or damage to the subject’s eyes (e.g., 
hemorrhage, retinal detachment, central corneal ulcer or damage to the optic 
nerve).

• A congenital anomaly/birth defect. 
Important medical events that may not result in death, are life-threatening, or 
require hospitalization may be considered serious when, based upon appropriate 
medical judgment, they may jeopardize the patient or subject and may require 
medical or surgical intervention to prevent one of the outcomes listed in this 
definition. 
9.3 Procedures for Reporting Adverse Events 
All adverse events and their outcomes must be reported to Ora, the study sponsor, and 
the IRB as required by the IRB, federal, state, or local regulations and governing 
health authorities and recorded on the appropriate eCRF.  
9.3.1 Reporting a Suspected Unexpected Adverse Reaction 
All adverse events that are ‘suspected’ and ‘unexpected’ are to be reported 
to Ora, the study sponsor and the IRB as required by the IRB, federal, 
state, or local regulations and governing health authorities. 
9.3.2 Reporting a Serious Adverse Event 
To ensure subject safety, all serious adverse events, regardless of 
relationship to the study drug, must be immediately reported.  All 
information relevant to the serious adverse event must be recorded on the 
appropriate eCRF.  The investigator is obligated to pursue and obtain 
information requested by Ora and/or the sponsor in addition to that 
information reported on the eCRF.  All subjects experiencing a serious 
adverse event must be followed up and the outcome reported. 
In the event of a serious adverse event, the investigator must notify Ora 
and the sponsor immediately (within 24 hours); obtain and maintain in 
his/her files all pertinent medical records, information, and medical 
judgments from colleagues who assisted in the treatment and follow-up of 
the subject; provide Ora and the study sponsor with a complete case 
history, which includes a statement as to whether the event was or was not 
suspected to be related to the use of the study drug; and inform the IRB of 
the adverse event within their guidelines for reporting serious adverse 
events.  
Serious adverse events should be reported within one day to the contacts 
listed below:

9.4 Procedures for Unmasking of Study Drug 
All subjects, investigators, and study personnel involved with the conduct of the study 
will be masked with regard to treatment assignments. When medically necessary, the 
investigator may need to determine what treatment arm has been assigned to a 
subject.  When possible (i.e., in non-emergent situations), Ora and/or the study 
sponsor should be notified before unmasking study drug. 
If an investigator identifies a medical need for unmasking the treatment assignment of 
a subject, he/she should contact Ora and/or the medical monitor prior to unmasking 
the identity of the IP, if possible. Ora will ask the site to complete and send them the 
Unmasking Request Form. Ora will notify Mitotech and jointly will determine if the 
unmasking request should be granted. They may consult the medical monitor as 
needed. The result of the request will be documented on the Unmasking Request 
Form. If approval is granted to unmask a subject, written permission via the 
Unmasking Request Form will be provided to the investigator. The investigator will 
unmask the subject 
. The investigator will complete the Unmasking 
Memo form and include it in the subject’s study file and provide a copy for the Trial 
Master File (TMF). For each unmasked request, the reason, date, signature, and name 
of the person who unmasked the subject, must be noted in the subject’s study file. 
9.5 Type and Duration of the Follow-up of Subjects after Adverse 
Events 
Adverse events that are ongoing at the end of the study visit will be followed.  Phone 
calls will be placed with any subject who experiences an adverse event until the issue 
is resolved or the condition is considered ongoing and stable.

11 COMPLIANCE WITH GOOD CLINICAL PRACTICES, 
ETHICAL CONSIDERATIONS, AND ADMINISTRATIVE 
ISSUES 
This study will be conducted in compliance with the protocol, Good Clinical Practices 
(GCPs), including the International Conference on Harmonization (ICH) Guidelines, and 
in general, consistent with the Declaration of Helsinki.  In addition, all applicable local, 
state, and federal requirements relevant to the use of study drugs in the countries involved 
will be adhered to. 
11.1 Protection of Human Subjects 
11.1.1 Subject Informed Consent 
Informed consent/assent must take place before any study specific 
procedures are initiated.  Signed and dated written informed consent must 
be obtained from each subject prior to enrollment into the study.   
All informed consent forms must be approved for use by the sponsor and 
receive approval/favorable opinion from an IRB prior to their use.  If the 
consent form requires revision (e.g., due to a protocol amendment or 
significant new safety information), it is the investigator’s responsibility to 
ensure that the amended informed consent is reviewed and approved by 
Ora prior to submission to the governing IRB and that it is read, signed 
and dated by all subjects subsequently enrolled in the study as well as 
those currently enrolled in the study. 
11.1.2 Institutional Review Board (IRB) Approval 
This study is to be conducted in accordance with Institutional Review 
Board regulations (U.S. 21 CFR Part 56.103).  The investigator must 
obtain appropriate IRB approval before initiating the study and re-
approval at least annually. 
Only an IRB approved version of the informed consent form will be used. 
11.2 Ethical Conduct of the Study 
This study will be conducted in accordance with the ethical principles that originated 
with the Declaration of Helsinki.

11.3 Subject Confidentiality 
All personal study subject data collected and processed for the purposes of this study 
should be maintained by the investigator and his/her staff with adequate precautions 
as to ensure that the confidentiality of the data in accordance with local, state, and 
federal laws and regulations. 
Monitors, auditors and other authorized representatives of Ora, the sponsor, the IRB 
approving this study, the FDA, the DHHS, other domestic government agencies, and 
other foreign regulatory agencies will be granted direct access to the study subject’s 
original medical and study records for verification of the data and/or clinical trial 
procedures. Access to this information will be permitted to the aforementioned 
individuals to the extent permitted by law. 
A report of the results of this study may be published or sent to the appropriate health 
authorities in any country in which the study drug may ultimately be marketed, but 
the subject’s identity will not be disclosed in these documents. 
11.4 Documentation 
Source documents may include a subject’s medical records, hospital charts, clinic 
charts, the investigator’s study subject files, as well as the results of diagnostic tests 
such as X-rays, laboratory tests, and EKGs.  The investigator’s copy of the eCRF 
serves as the investigator’s record of a subject’s study-related data. 
11.4.1 Retention of Documentation 
All study-related source documents, correspondence, patient records, 
consent forms, record of the distribution and use of all study drug and 
copies of case report forms should be maintained on file for at least two 
years after the last approval of a marketing application in an ICH region 
and until there are no pending or contemplated marketing applications in 
an ICH region; or until at least two years have elapsed since the formal 
discontinuation of clinical development of the study drug. These 
documents will be retained for a longer period if required by the 
applicable regulatory requirements or by an agreement with the sponsor.  
It is the responsibility of the sponsor to inform the investigator/institution 
as to when these documents no longer need to be retained. 
If the responsible investigator retires, relocates, or for other reasons 
withdraws from the responsibility of keeping study records, custody must 
be transferred to a person who will accept the responsibility.  The sponsor 
must be notified in writing of the name and address of the new custodian.
