Introduction
2.1.
Study Rationale
The efficient community spread of SARS-CoV-2 has resulted in the current pandemic of 
COVID-19, which in severe and critical cases results in progressive pulmonary infection, 
complicated by respiratory failure, with a high prevalence of acute respiratory distress syndrome. 
Although several therapies have been explored in severe COVID-19, none have improved 
survival, including antivirals, glucocorticoids, and immunoglobulins (Liu et al 2020). 
This study aims to characterize the real-world effectiveness of bamlanivimab in participants with 
mild-to-moderate COVID-19 in adults adolescents (age ≥12) who are at high risk of progressing 
to severe COVID-19 and/or hospitalization compared to a similar control population.
2.2.
Background
The SARS-CoV-2 gains entry to cells through binding of the spike (S) protein to ACE2 receptors 
on cells (Hoffmann 2020). Eli Lilly and Company has a partnership with AbCellera Biologics 
Inc. (AbCellera; Vancouver, Canada) to develop neutralizing IgG1 mAbs to the spike (S) protein 
of SARS-CoV-2 as a potential treatment for COVID-19. Candidate antibody gene sequences 
have been selected from a recently recovered COVID-19 US patient’s serum using AbCellera’s 
core platform screening technologies.
2.3.
Benefit/Risk Assessment
Anticipated risk is considered low and is based on the known mechanism of action for human-
derived neutralizing antibodies in acute viral disease states. A theoretical risk is that this 
intervention may cause ADE of viral replication. This is based on responses observed to some 
monoclonal antibody therapies used in other unrelated viral diseases. Unlike ADE associated 
with dengue and Zika virus infections, this phenomenon has not been clearly established for 
coronavirus infections, such as SARS and Middle East respiratory syndrome, and has not been 
reported to date with SARS-CoV-2. Additionally, limited experience with the use of 
convalescent serum as a treatment for patients with severe COVID-19 disease has not indicated 
safety concerns (Shen et al. 2020; Duan et al. 2020). 
The risk of clinical ADE for either intervention or in combination is considered low due to 

the absence of ADE from in vitro studies, and

the absence of ADE from in vivo nonhuman primate studies for bamlanivimab.
To date, there is no evidence of productive enhancement of ADE with SARS-CoV-2. 
Additional manageable risks associated with most therapeutic monoclonal antibodies are the 
potential for infusion-related hypersensitivity and cytokine release reactions. The single infusion 
in this study will be administered at a controlled rate, the study participants will be monitored 
closely, and adjustments in the infusion rate will be made and/or the infusion stopped, if 
indicated. Additional information regarding infusion reaction management options is located in
Section 6.1.1.2.

Protocol J2X-MC-PYAJ

Given the totality of data on bamlanivimab, the well-established safety profile of other 
therapeutic mAbs, and the lack of disease-directed therapeutic options for patients with COVID-
19 illness or to prevent the SARS-CoV-2 infection, the overall benefit or risk assessment of this 
study is considered favorable.
More detailed information about the known and expected benefits and risks and reasonably 
expected adverse events of bamlanivimab may be found in the IB.

Study Design
4.1.
Overall Design
This study is being conducted in the same population as in the Emergency Use Authorization 
(EUA [FDA 2020a]). 
Study J2X-MC-PYAJ is an open-label, single-arm, prospective, cohort study using matched real-
world external controls. There is no placebo arm.
Screening
Interested participants or their legally authorized representative will sign the appropriate 
informed consent and child or adolescent assent document(s), as appropriate, prior to completion 
of any procedures. The participant may enter the study with a previous positive SARS-CoV-2 
viral test result from an external testing facility. This test result must be the first time the 
participant has had a positive RT-PCR or antigen testing confirmation for COVID-19 (if antigen 
test is accompanied by symptoms suggestive of SARS-CoV-2 infection)for SARS-CoV-2. 
Prescreening prior to administration of bamlanivimab may be conducted to collect baseline 
information.
The investigator will review symptoms, risk factors, and other non-invasive inclusion and 
exclusion criteria prior to any invasive procedures. If the participant is eligible after this review, 
then the site will perform the invasive procedures.
Treatment and Assessment Period
This is the general sequence of events during the treatment and assessment period:

complete baseline procedures to confirm eligibility (positive COVID-19 test, high-risk 
criteria per EUA)

participants receive study intervention, and

complete all safety monitoring and post-infusion data collection.

Scientific Rationale for Study Design
Overall Design
This study is designed to characterize the real-world effectiveness of bamlanivimab in 
participants with mild-to-moderate COVID-19 in adults and children who are at high risk of 
progressing to severe COVID-19 and/or hospitalization compared to a similar control population.
Participant Characteristics
The participant population are those infected with SARS-CoV-2 who are at high risk of 
developing severe disease requiring hospitalization. There is historical evidence that patients 
infected with upper respiratory viruses who are treated early in their disease course have better 
responses to anti-viral therapies (Aoki et al., 2003); all patients in the treated cohort will receive 
an infusion of bamlanivimab within 10 days of their positive COVID-19 test.

CONFIDENTIAL
Protocol J2X-MC-PYAJ
18
The population of participants with mild-to-moderate COVID-19 illness who are at high risk of 
developing severe disease per the EUA was chosen to evaluate if effective antiviral antibody 
therapy may prevent progression to the severe form of COVID-19 illness by treating this 
population early in their disease course and prior to respiratory compromise and failure. 
Participants with these risk factors are at higher risk for more severe disease and hospitalization. 
This population was chosen to evaluate if effective antiviral antibody therapy may prevent 
hospitalization or death. 
4.3.
Justification for Dose
Bamlanivimab-700 mg was estimated as the maximum therapeutic dose based on PK/PD viral 
dynamics modeling of Study J2W-MC-PYAB and has a sustained concentration above the in 
vitro IC90 of viral cell-entry neutralization in the lung tissue (95th percentile of the estimates 
used) for at least 28 days in 90% of the participant population.
4.4.
End of Study Definition
A participant is considered to have completed the study if they have completed all required 
phases of the study including the last scheduled procedure shown in the SoA (Section 1.3).
The end of the study is defined as the date of last scheduled procedure shown in the SoA
(Section 1.3) for the last participant in the trial.

Special Treatment Considerations
6.1.1.1.
Premedication for Infusions
Premedication for infusions is not planned. However, if an infusion reaction occurs during 
administration or if the participant has a medical history suggesting a potential benefit from 
premedication, the study investigator(s) should determine the appropriate premedication. The 
investigators and sponsor may decide to use premedication if the frequency of infusion reactions 
among participants warrants it.
If minor infusion reactions are observed, administration of acetaminophen, 500 to 1000 mg, 
antihistamines, and/or other appropriately indicated medications may be given prior to the start 
of infusions for subsequent participants. 

CONFIDENTIAL
Protocol J2X-MC-PYAJ

The decision to implement premedication for infusions in subsequent participants will be made 
by the investigator and sponsor and recorded in the study documentation.
Any premedications given will be documented as a concomitant therapy.
6.1.1.2.
Management of Infusion Reactions
Access to medications (e.g., epinephrine, norepinephrine, steroids, and diphenhydramine) for 
potential anaphylaxis and serious infusion reactions is mandatory at all infusion sites.
Symptoms and Signs
Symptoms and signs that may occur as part of an infusion reaction include, but are not limited to,
fever, chills, nausea, headache, bronchospasm, hypotension, angioedema, throat irritation, rash
including urticaria, pruritus, myalgia, and dizziness.
Infusion-related reaction severity will be assessed and reported using the DAIDS Table for 
Grading the Severity of Adult and Pediatric Adverse Events, version 2.1 (July 2017).

Preparation/Handling/Storage/Accountability
The investigator or designee must confirm appropriate storage conditions have been maintained 
during transit for all study intervention received and any discrepancies are reported and resolved 
before use of the study intervention.
Only participants enrolled in the study may receive study intervention, and only authorized site 
staff may supply or administer study intervention. 
All study intervention must be stored in a secure, environmentally controlled, and monitored 
(manual or automated) area in accordance with the labeled storage conditions with access limited 
to the investigator and authorized study personnel.
The investigator or designee is responsible for study intervention accountability, reconciliation, 
and record maintenance (i.e., receipt, reconciliation, and final disposition records).
Further guidance and information for the final disposition of unused study interventions are 
provided in the pharmacy manual.
6.3.
Measures to Minimize Bias: Randomization and Blinding
Propensity Score Matching
The non-randomized nature of a cohort study introduces the possibility of bias. Therefore, the 
analysis will use propensity score (PS) matching using risk factors associated with 
hospitalization for COVID-19. The purpose of PS matching is to create balance in the 2 cohorts 
on specific relevant covariates. PS will be estimated for each patient in the bamlanivimab group 
and the comparator cohort by the logistic regression model, with treatment status as the 
dependent variable and the pre-defined independent variables considered as the potential 
confounders. The success of the PS is judged by the balance in the confounder distributions it 
produces between the 2 study groups. Prior to initiating the outcome analysis, the quality of the 
PS adjustment and associated assumptions will be evaluated. The PS model will be finalized 
prior to initiating the analysis of the outcome measure. Further details will be provided in the 
SAP.
6.4.
Study Intervention Compliance
Participants will receive study intervention directly from the investigator or designee, under 
medical supervision. The date and time of dosing will be recorded in the source documents and 
recorded in the CRF. The dose of study intervention and study participant identification will be 
confirmed at the time of dosing by a member of the study site staff other than the person 
administering the study intervention.
6.5.
Concomitant Therapy
Prior Treatment
Convalescent COVID-19 plasma treatment is not allowed prior to enrollment.
For adolescent participants, record any vaccines received 90 days prior to signing informed 
consent.

CONFIDENTIAL
Protocol J2X-MC-PYAJ
26
Concomitant Therapy
Participants should be treated according to standard of care, even as it evolves, and medications 
may be part of the treatment paradigm. Therefore, remdesivir, or baricitinib plus remdesivir, may 
be initiated as standard of care for participants hospitalized with severe disease (if available 
through the FDA EUAs) if hospitalization occurs following infusion of bamlanivimab. 
If the local standard of care per written policies or guidelines (i.e., not just an individual clinician 
decision) includes lopinavir or ritonavir, chloroquine, hydroxychloroquine, or other 
investigational agents, then initiating these during the study (after infusion of bamlanivimab) is 
permitted but may require additional safety monitoring by the site.
Any medication, investigational agent, or vaccine, including over-the-counter or prescription 
medicines, vitamins, and/or herbal supplements, or other specific categories of interest that the 
participant is receiving at the time of enrollment or receives during the study must be recorded 
along with

reason for use

dates of administration including start and end dates, and

dosage information including dose and frequency for concomitant therapy of special 
interest.
Acetaminophen and corticosteroid use are permitted at any time during the study.
Other concomitant medication may be considered on a case-by-case basis by the investigator in 
consultation with the sponsor if required.
The sponsor should be contacted if there are any questions regarding concomitant or prior 
therapy.

Discontinuation of Study Intervention and Participant 
Discontinuation/Withdrawal
Discontinuation of specific sites or that of the trial as a whole are handled as part of regulatory, 
ethical, and trial oversight considerations in Section 10.1, Appendix 1.
7.1.
Discontinuation of Study Intervention
In rare instances, it may be necessary for a participant to permanently discontinue study 
intervention. If the IV infusion is definitively discontinued, the participant will remain in the 
study for the remainder of the assessment visits through Day 90.
7.2.
Participant Discontinuation/Withdrawal from the Study
A participant may withdraw from the study 

at any time at his or her own request

at the request of his or her designee (e.g., parents or legal guardian)

at the discretion of the investigator for safety, behavioral, compliance, or administrative 
reasons, and

if enrollment in any other clinical study involving an investigational product or 
enrollment in any other type of medical research judged not to be scientifically or 
medically compatible with this study.
Discontinuation is expected to be uncommon.
At the time of discontinuation, if possible, an early discontinuation phone call should be 
conducted to ascertain SAEs/AEs, as described in the SoA (Section 1.3).
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, they may request destruction of any samples taken and not tested, and 
the investigator must document this in the site study records.
7.2.1.
Discontinuation of Inadvertently Enrolled Participants
If the sponsor or investigator identifies a participant who did not meet enrollment criteria and 
was inadvertently enrolled, then the participant should be discontinued from study intervention
unless there are extenuating circumstances that make it medically necessary for the participant to 
continue study intervention.
If the investigator and the sponsor CRP agree it is medically appropriate to continue, the 
investigator must obtain documented approval from the sponsor CRP to allow the inadvertently 
enrolled participant to continue in the study with or without treatment with investigational 
product.
Safety follow-up is as outlined in

scheduled visits and is unable to be contacted by the study site. Site personnel or designee are 
expected to make diligent attempts to contact participants who are unavailable for a scheduled 
visit or were otherwise unable to be followed up by the site.
Site personnel, or an independent third party, will attempt to collect the vital status of the 
participant within legal and ethical boundaries for all participants that received study 
intervention. Public sources may be searched for vital status information. If vital status is 
determined to be deceased, this will be documented and the participant will not be considered 
lost to follow-up. Sponsor personnel will not be involved in any attempts to collect vital status 
information.

Study Assessments and Procedures
Study procedures and their timing are summarized in the SoA (Section 1.3).
Protocol waivers or exemptions are not allowed.
After signing of informed consent, any immediate safety concerns should be discussed with the 
sponsor immediately upon occurrence or awareness to determine if the participant should 
continue or discontinue study intervention. All outlined AE or SAE reporting must be done as 
applicable.
Adherence to the study design requirements, including those specified in the SoA (Section 1.3), 
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.
Data for this study will be collected from telephone calls and the EMR. 
8.1.
Efficacy Assessments
Hospitalization events (Section 8.2.2) will be used to characterize the primary outcome. 
8.2.
Safety Assessments
Planned time points for all safety assessments are provided in the SoA (Section 1.3).
8.2.1.
Vital Signs
Vital signs will be measured as specified in the SoA (Section 1.3) at the infusion visit. Vital 
signs include

body temperature

blood pressure

pulse rate

respiration rate

saturation of peripheral oxygen, and

supplemental oxygen flow rate, FiO2 if known, and method of delivery, if applicable.
Additional vital signs may be measured during the study if warranted, as determined by the 
investigator.
8.2.2.
Hospitalization Events
If a participant is admitted to the hospital, the participant will remain in the study and follow the 
procedures outlined in the SoA (Section 1.3). Hospitalization is defined as ≥24 hours of acute 
care.
The date of hospitalization events will be recorded in the CRF and includes

hospitalization


emergency room visit 

ICU admittance

extended care facility admittance, and 

discharge.
8.3.
Adverse Events and Serious Adverse Events
AEs will be reported by the participant, or, when appropriate, by a caregiver, surrogate, or the 
participant’s legally authorized representative. Hospitalization, ED, visits, and deaths from 
COVID-19 are captured as endpoints and not as AEs or SAEs (see Section 10.2.1).
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 intervention or study procedures, or that 
caused the participant to discontinue the study intervention or study.
8.3.1.
Time Period and Frequency for Collecting AE and SAE Information
All AEs and SAEs will be collected from the time of signing of the ICF until participation in 
study has ended.
Adverse events that begin before the start of study intervention but after signing of the ICF will 
be recorded on the Adverse Event CRF.
Although all AEs after signing the ICF are recorded by the site in the CRF/electronic data entry, 
SAE reporting to sponsor begins after the participant has signed the ICF and has received study 
intervention. However, if an SAE occurs after signing the ICF, but prior to receiving study 
intervention, it needs to be reported within the SAE reporting timeframe if it is considered 
reasonably possibly related to study procedures.
All SAEs will be recorded and reported to the sponsor or designee immediately and under no 
circumstance should this exceed 24 hours of awareness, as indicated in Section 10.2, Appendix 
2. 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 after conclusion of the study 
participation. 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 or she considers the event to be 
reasonably related to the study intervention or study participation, the investigator must promptly 
notify the sponsor.
8.3.2.
Method of Detecting AEs and SAEs
The method of recording, evaluating, and assessing causality of AE and SAE and the procedures 
for completing and transmitting SAE reports are provided in Section 10.2.
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.

CONFIDENTIAL
Protocol J2X-MC-PYAJ
31
8.3.3.
Follow-Up of AEs and SAEs
After the initial AE or SAE report, the investigator is required to proactively follow each 
participant at subsequent visits or 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 7.3). Further information on follow-up procedures is provided in Section 10.2.
8.3.4.
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 
intervention 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 intervention under clinical investigation. The 
sponsor will comply with country-specific regulatory requirements relating to safety reporting to 
the regulatory authority, IRB/IEC, and investigators.
An investigator who receives an investigator safety report describing an SAE or other specific 
safety information (e.g., summary or listing of SAEs) from the sponsor will review and then file 
it with the IB and will notify the IRB/IEC, if appropriate according to local requirements.
8.3.5.
Pregnancy
Details of all pregnancies in female participants will be collected for 90 days after pregnancy
outcome.
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 Section 10.3, Appendix 3.
Abnormal pregnancy outcomes, for example, spontaneous abortion, fetal death, stillbirth, 
congenital anomalies, and ectopic pregnancy, are considered SAEs.
8.3.6.
Hypersensitivity Reactions
Many drugs, but particularly biologic agents, carry the risk of systemic hypersensitivity 
reactions.
If such a reaction occurs, additional details describing each symptom should be provided to the 
sponsor in the infusion-related reaction/hypersensitivity CRF.
Sites should have appropriately trained medical staff and appropriate medical equipment 
available when study participants are receiving intervention. It is recommended that participants
who experience a systemic hypersensitivity reaction be treated per the local standard of care.
8.3.7. Infusion-related Reactions
As with other mAbs, infusion-related reactions may occur during or following IV administration. 
If an infusion-related reaction occurs, additional data describing each symptom and sign should 
be provided to the sponsor in the CRF.

8.3.8. Product Complaints
A product complaint is any written, electronic, or oral communication that alleges deficiencies 
related to the identity, quality, durability, reliability, safety, effectiveness, or performance of a 
trial intervention. This may include reporting of any medication errors whether or not associated 
with an adverse event.
Sponsor collects product complaints on study intervention and drug delivery systems used in 
clinical studies in order to ensure the safety of study participants, monitor quality, and to 
facilitate process and product improvements.
Participants will be instructed to contact the investigator as soon as possible if they have a 
complaint or problem with the intervention so that the situation can be assessed.
NOTE: AEs/SAEs that are associated with a product complaint will also follow the processes 
outlined in Section 8.3.3 and Appendix 10.2 of the protocol.
Time Period for Detecting Product Complaints
Product complaints that result in an adverse event will be detected, documented, and reported to 
the sponsor during all periods of the study in which the intervention is used.
If the investigator learns of any product complaint at any time after a participant has been 
discharged from the study, and such incident is considered reasonably related to an intervention
provided for the study, the investigator will promptly notify the sponsor.
Prompt Reporting of Product Complaints to Sponsor
Product complaints will be reported to the sponsor within 24 hours after the investigator becomes 
aware of the complaint.
The Product Complaint Form will be sent to the sponsor by a method designated by the sponsor.
Follow-Up of Product Complaints
Follow-up applies to all participants, including those who discontinue study intervention.
The investigator is responsible for ensuring that follow-up includes any supplemental 
investigations as indicated to elucidate the nature and/or causality of the product complaint.
New or updated information will be recorded on the originally completed form with all changes 
signed and dated by the investigator and submitted to the sponsor.

Statistical Considerations
9.1.
Statistical Hypotheses
The null hypothesis is that the proportions of bamlanivimab-treated and control patients with
COVID-19-related hospitalization by Day 29 will be similar.
9.2.
Sample Size Determination
Sample Size
A sample size of at least 500 treated patients (and 500 control patients) will provide 
approximately 90% power to detect a treatment difference for the primary analysis, assuming the 
true rates of hospitalization are 12% in the control group and at most 6% in the treated group 
using a 2-sided 0.05 level analysis (accounting for 5% lost to follow up). For the exploratory 
subset analyses, a comparison of the effectiveness of treatment within multiple subsets based on 
age, comorbidities and other potential factors is of interest.  A total sample size of 3000 in each 
group will provide at least 90% power under the same assumptions within each subgroup of 
interest, as long as the subset makes up at least 17% of the full population.  This also assumes no 
multiplicity adjustment in the subset analyses.
A full discussion of power calculations will be provided in the SAP.
9.3.
Populations for Analyses
This table defines the populations for analysis. 
Population
Description
Entered
All participants who sign the informed consent form.
Efficacy
All participants who received study intervention and provided at least one 
post-baseline measure for the relevant endpoint. Participants will be analyzed 
according to whether they received the study intervention (treated group,
control group).
Safety
All participants who received study intervention.
9.4.
Statistical Analyses
The primary analysis is a comparison of rates of hospitalization for COVID-19 between treated 
patients and the control group in the Efficacy population. The pool of potential control patients 
will be obtained from patients in the EMR/claims data populations who meet the study entry 
criteria and would qualify for bamlanivimab treatment (but did not receive it). PS matching using 
risk factors associated with hospitalization for COVID-19 will be used to create a control group 
from the pool of potential control patients that provide balance with the treated patients on the
relevant covariates. PS will be estimated for each patient in the bamlanivimab group and the 
comparator cohort by the logistic regression model, with treatment status as the dependent 
variable and the pre-defined independent variables considered as the potential confounders. For 
the PS matching process, each eligible patient receiving bamlanivimab will be matched to a 
control patient by a greedy 1:1 matching algorithm (D’Agostino 1998) with sampling without 

CONFIDENTIAL
Protocol J2X-MC-PYAJ
35
replacement. The algorithm will utilize logit of PS with a caliper of 0.2 standard deviations of the 
logit of the PS (Austin 2014). 
The success of the propensity score is judged by the balance in the confounder distributions it 
produces between the 2 study groups. Prior to initiating the outcome analysis, the quality of the 
PS adjustment and associated assumptions will be evaluated. The PS model will be finalized 
prior to initiating the analysis of the outcome measure. 
The primary analysis will then be a comparison of the proportions of patients with a COVID-19-
related hospitalization by Day 29 between the 2 treatment groups using a logistic regression
model adjusting for variables a priori expected to be related to the outcome. Similarly, secondary 
analyses will include comparisons of the proportions of patients with COVID-19-related 
hospitalizations by Days 60 and 90, COVID-19-related ED visits, and COVID-19-related 
mortality through Days 29, 60, and 90 between the treatment groups, and will describe AEs and 
SAEs in bamlanivimab-treated patients. These details will be documented in the SAP prior to 
analysis.

Supporting Documentation and Operational Considerations
10.1.
Appendix 1: Regulatory, Ethical, and Study Oversight 
Considerations
10.1.1.
Regulatory and Ethical Considerations
This study will be conducted in accordance with the protocol and with the following:

consensus ethical principles derived from international guidelines including the 
Declaration of Helsinki and Council for International Organizations of Medical Sciences 
International Ethical Guidelines

applicable International Council for Harmonization (ICH) Good Clinical Practice (GCP) 
Guidelines, and

applicable laws and regulations.
The protocol, protocol amendments, ICF, IB, and other relevant documents (e.g., advertisements) 
must be submitted to an IRB/IEC by the investigator and reviewed and approved by the IRB/IEC 
before the study is initiated.
Any amendments to the protocol will require IRB/IEC approval before implementation of 
changes made to the study design, except for changes necessary to eliminate an immediate 
hazard to study participants.
The investigator will be responsible for the following:

providing written summaries of the status of the study to the IRB/IEC annually or more 
frequently in accordance with the requirements, policies, and procedures established by 
the IRB/IEC

notifying the IRB/IEC of SAEs or other significant safety findings as required by 
IRB/IEC procedures, and

providing oversight of the conduct of the study at the site and adherence to requirements 
of 21 CFR, ICH guidelines, the IRB/IEC, European regulation 536/2014 for clinical 
studies (if applicable), and all other applicable local regulations.
Investigator sites are compensated for participation in the study as detailed in the CTA.
10.1.2.
Financial Disclosure
Investigators and sub-investigators will provide the sponsor with sufficient, accurate financial 
information as requested to allow the sponsor to submit complete and accurate financial 
certification or disclosure statements to the appropriate regulatory authorities. Investigators are 
responsible for providing information on financial interests during the study and for 1 year after 
the completion of the study.
10.1.3.
Informed Consent Process
The investigator or his/her representative will explain the nature of the study, including the risks 
and benefits, to the participant or their legally authorized representative and answer all questions 
regarding the study.

CONFIDENTIAL
Protocol J2X-MC-PYAJ
38
Participants must be informed that their participation is voluntary. Participants or their legally 
authorized representative will be required to sign a statement of informed consent and 
child/adolescent assent, as appropriate, that meets the requirements of 21 CFR 50, local 
regulations, ICH guidelines, Health Insurance Portability and Accountability Act requirements, 
where applicable, and the IRB/IEC or study center.
Due to strict respiratory isolation policies, limited access to COVID-19 patient rooms, and 
SARS-CoV-2 transmissibility via droplet-contaminated paper, verbal consent, and alternative 
methods of obtaining consent (e.g., by phone) will be allowed if approved by the IRB. 
If a signed paper copy of the ICF or child/adolescent assent is allowed by site/institution policy, 
then the process of how it will be obtained and stored will need to be determined.
Any variation from the standard consent process due to isolation and infection control should be 
sent to the IRB for approval prior to enrollment. The site will document the process in their 
regulatory files and demonstrate that the process has IRB concurrence or approval.
The medical record must include a statement that written informed consent or child/adolescent 
assent (if deemed appropriate by local ethics review) was obtained before the participant was 
entered in the study and the date the written consent or assent was obtained. The authorized 
person obtaining the informed consent or child/adolescent assent, and, if applicable, the 
individual designated to witness a verbal consent, must also sign the ICF. The medical record 
should also describe how the investigator determined that the person signing the ICF was the 
participant’s legally authorized representative (parent/guardian).
Participants and (when applicable) their legally acceptable representative, parent(s), or legal 
guardian must be re-consented to the most current version of the ICF(s) during their participation 
in the study, per the reconsenting guidelines as appropriate. Verbal reconsenting and alternative 
methods of obtaining consent may be utilized if approved by the IRB.
Minor participants must be re-consented if they reach the age of majority during the course of 
study, in order to continue participating.
A copy of the ICF(s) must be provided to the participant or the participant’s legally authorized 
representative and is kept on file.
10.1.4.
Data Protection
Participants will be assigned a unique identifier by the sponsor. Any participant records, datasets,
or tissue samples that are transferred to the sponsor will contain the identifier only; participant 
names or any information which would make the participant identifiable will not be transferred.
The participant must be informed that their personal study-related data will be used by the 
sponsor in accordance with local data protection law. The level of disclosure must also be 
explained to the participant who will be required to give consent for their data to be used as 
described in the informed consent.
The participant must be informed that their medical records may be examined by Clinical 
Quality Assurance auditors or other authorized personnel appointed by the sponsor, by 
appropriate IRB/IEC members, and by inspectors from regulatory authorities.

CONFIDENTIAL
Protocol J2X-MC-PYAJ
39
The sponsor has processes in place to ensure data protection, information security, and data 
integrity. These processes include appropriate contingency plan(s) for appropriate and timely 
response in the event of a data security breach.
10.1.5.
Dissemination of Clinical Study Data
A clinical study report will be provided for this study and a summary of study information 
provided on publicly available websites. 
10.1.6.
Data Quality Assurance
Investigator responsibilities
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.
Data monitoring and management
The monitoring plan includes

monitoring details describing strategy, for example, risk-based initiatives in operations 
and quality, such as Risk Management and Mitigation Strategies and Analytical Risk-
Based Monitoring 

methods 

responsibilities and requirements 

handling of noncompliance issues, and 

monitoring techniques.
The sponsor or designee is responsible for the data management of this study including quality 
checking of the data. The sponsor assumes accountability for actions delegated to other 
individuals (e.g., Contract Research Organizations).
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. They will also ensure 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.
If on-site monitoring activities cannot occur, alternative measures will be used. Examples of 
alternative measures are use of technology for off-site monitoring or providing pseudonymized 
copies of source documents to the monitor electronically. The remote source data verification 
will be focused on critical efficacy data and important safety data.
Records retention and audits

CONFIDENTIAL
Protocol J2X-MC-PYAJ
40
Records and documents, including signed ICFs, pertaining to the conduct of this study must be 
retained by the investigator for the time period outlined in the CTA 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.
The sponsor or its representatives will periodically check a sample of the participant data 
recorded against source documents at the study site. The study may be audited by the sponsor or 
its representatives, and by regulatory agencies at any time. Investigators will be given notice 
before an audit occurs.
Data capture system
The investigator is responsible for ensuring the accuracy, completeness, legibility, and timeliness 
of the data reported to the sponsor.
An EDC system will be used in this study for the collection of CRF data. The investigator 
maintains a separate source for the data entered by the investigator or designee into the 
sponsor-provided EDC system.
Only symptom assessments might be directly recorded by the investigator site personnel or a 
delegate into the EDC. The directly entered data will serve as source documentation. The 
investigator will not maintain an original, separate, written, or electronic record of these data. A 
certified copy of the respective data entry will be downloaded by the investigator for retention.
The investigator is responsible for the identification of any data to be considered source and for 
the confirmation that data reported are accurate and complete by signing the CRF.
Data collected via the sponsor-provided data capture systems will be stored at third parties. The 
investigator will have continuous access to the data during the study and until decommissioning 
of the data capture systems. Prior to decommissioning, the investigator will receive an archival 
copy of pertinent data for retention.
Data managed by a central vendor, such as laboratory test data, will be stored electronically in 
the central vendor’s database system, and reports will be provided to the investigator for review 
and retention. Data will subsequently be transferred from the central vendor to the sponsor data 
warehouse.
Data from complaint forms submitted to sponsor will be encoded and stored in the global 
product complaint management system.
10.1.7.
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 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. Current medical 
records must be available.

The definition of what constitutes source data can be found in Section 10.1.6.
10.1.8.
Study and Site Start and Closure
The study start date is the date on which the clinical study will be open for recruitment of 
participants.
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 enough 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, or

discontinuation of further study intervention development.
If the study is prematurely terminated or suspended, the sponsor shall promptly inform the 
investigators, the IECs/IRBs, the regulatory authorities, and any contract research organization(s) 
used in the study of the reason for termination or suspension, as specified by the applicable 
regulatory requirements. The investigator shall promptly inform the participants and assure 
appropriate participant therapy and/or follow-up.
10.1.9.
Publication Policy
In accordance with the sponsor’s publication policy, the results of this study will be submitted 
for publication by a peer-reviewed journal if the results are deemed to be of significant medical 
importance.

Appendix 2: Adverse Events: Definitions and Procedures for 
Recording, Evaluating, Follow-Up, and Reporting
10.2.1.
Definition of AE
AE Definition

An AE is any untoward medical occurrence in a patient or clinical study participant, 
temporally associated with the use of study intervention, whether or not considered 
related to the study intervention.

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 intervention.
Events Meeting the AE Definition

Any abnormal laboratory test results (hematology, clinical chemistry, or urinalysis) or 
other safety assessments (e.g., ECG, radiological scans, and vital signs measurements), 
including those that worsen from baseline, considered clinically significant in the 
medical and scientific judgment of the investigator (i.e., not related to progression of 
underlying disease).

Exacerbation of a chronic or intermittent preexisting condition including either an 
increase in frequency and/or intensity of the condition.

New conditions detected or diagnosed after study intervention 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 
intervention or a concomitant medication. Overdose per se will not be reported as an 
AE or SAE unless it is an intentional overdose taken with possible suicidal/self-
harming intent. Such overdose should be reported regardless of sequelae. 

“Lack of efficacy” or “failure of expected pharmacological action” per se will not be 
reported as an AE or SAE. Such instances will be captured in the efficacy assessments. 
However, the signs, symptoms, and/or clinical sequelae resulting from lack of efficacy 
will be reported as AE or SAE if they fulfill the definition of an AE or SAE. 
Events NOT Meeting the AE Definition

The following study-specific clinical events related to COVID-19 are exempt from 
adverse event reporting unless the investigator deems the event to be related to the 
administration of study intervention:
o
hypoxemia due to COVID-19 requiring supplemental oxygen
o
hypoxemia due to COVID-19 requiring non-invasive ventilation or high flow 
oxygen devices, and

CONFIDENTIAL
Protocol J2X-MC-PYAJ
43
o
respiratory failure due to COVID-19 requiring invasive mechanical ventilation 
or ECMO.

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.

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 and 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 preexisting disease(s) or condition(s) present or 
detected at the start of the study that do not worsen.
10.2.2.
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).
An SAE is defined as any untoward medical occurrence that, at any dose:
a.
Results in death
b.
Is life-threatening
The term “life-threatening” in the definition of “serious” refers to an event in which the 
participant is 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 admitted to hospital
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 preexisting condition that did not worsen 
from baseline is not considered an AE.
d.
Results in persistent disability/incapacity

The term disability means a substantial disruption of a person’s ability to conduct 
normal life functions.

CONFIDENTIAL
Protocol J2X-MC-PYAJ
44

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 1 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.
10.2.3.
Recording and Follow-Up of AE and/or SAE
AE and SAE Recording

When an AE or SAE occurs, it is the responsibility of the investigator to review all 
documentation (e.g., hospital progress notes, laboratory reports, and diagnostics 
reports) related to the event.

The investigator will then record all relevant AE or SAE information in the CRF.

It is not acceptable for the investigator to send photocopies of the participant’s medical 
records to Sponsor or designee in lieu of completion of the AE or SAE CRF page.

There may be instances when copies of medical records for certain cases are requested 
by Sponsor or designee. 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 Sponsor or designee.

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 or 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, which together with serious (i.e., SAE) 
criteria on the AE CRF (“results in death” and “life-threatening”), are aligned with the DAIDS 
Table for Grading the Severity of Adult and Pediatric Adverse Events, version 2.1 (July 2017).

CONFIDENTIAL
Protocol J2X-MC-PYAJ
45
Mild: Mild symptoms causing no or minimal interference with usual social and functional 
activities, with intervention not indicated.
Moderate: Moderate symptoms causing greater than minimal interference with usual 
social and functional activities, with intervention indicated.
Severe: Severe symptoms causing inability to perform usual social and functional 
activities, with intervention or hospitalization indicated.
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 intervention and 
each occurrence of each AE or 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 intervention 
administration will be considered and investigated.

The investigator will also consult the IB and/or Product Information, for marketed 
products, in his or her assessment.

For each AE or SAE, the investigator must document in the medical notes that he or 
she has reviewed the AE or SAE and has provided an assessment of causality.

There may be situations in which an SAE has occurred and the investigator has 
minimal information to include in the initial report to Sponsor or designee. However, it 
is very important that the investigator always make an assessment of causality for 
every event before the initial transmission of the SAE data to Sponsor or designee.

The investigator may change his or her opinion of causality in light of follow-up 
information and send an SAE follow-up report with the updated causality assessment.

The causality assessment is 1 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 Sponsor or 
designee to elucidate the nature and/or causality of the AE or SAE as fully as possible. 
This may include additional laboratory tests or investigations, histopathological 
examinations, or consultation with other health care professionals.

CONFIDENTIAL
Protocol J2X-MC-PYAJ
46

If a participant dies during participation in the study or during a recognized follow-up 
period, the investigator will provide Sponsor or designee with a copy of any 
postmortem findings including histopathology. 

New or updated information will be recorded in the originally completed CRF.

The investigator will submit any updated SAE data to Sponsor or designee within 24 
hours of receipt of the information. 
10.2.4.
Reporting of SAEs
SAE Reporting via an Electronic Data Collection Tool

The primary mechanism for reporting an SAE will be the electronic data collection 
tool.

If the electronic system is unavailable, then the site will use the paper SAE data 
collection tool (see next section) in order to report the event within 24 hours.

The site will enter the SAE data into the electronic system as soon as it becomes 
available.

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 to the sponsor by telephone.

Contacts for SAE reporting can be found in site training documents.
SAE Reporting via Paper CRF

Facsimile transmission of the SAE paper CRF is the preferred method to transmit this 
information to the sponsor.

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 site training documents.
10.2.5.
Medication Error
FDA defines medication error as any preventable event that may cause or lead to inappropriate 
medication use or patient harm while the medication is in the control of a healthcare provider, 
patient, or consumer (FDA 2020b).

Appendix 3: Contraceptive Guidance and Collection of Pregnancy 
Information
Definitions:
Women
Woman of Childbearing Potential
A woman is considered fertile following menarche and until becoming postmenopausal unless 
permanently sterile (see below).
If fertility is unclear (e.g., amenorrhea in adolescents or athletes) and a menstrual cycle cannot be 
confirmed before first dose of study intervention, additional evaluation should be considered.
Woman not of Childbearing Potential
Women in the following categories are not considered women of childbearing potential:
1. premenarchal
2. premenopausal female with either
a.
documented hysterectomy
b. documented bilateral salpingectomy, or
c.
documented bilateral oophorectomy.
For individuals with permanent infertility due to an alternate medical cause other than the above, 
(e.g., Müllerian agenesis, androgen insensitivity), investigator discretion should be applied to 
determining study entry.
Note: Determination can come from the site personnel’s review of the participant’s medical 
records, medical examination, or medical history interview.
3. Postmenopausal female is defined as, women with:
d. 12 months of amenorrhea for women >55, with no need for FSH
e.
12 months of amenorrhea for women >40 years old with FSH ≥40 mIU/mL and 
no other medical condition such as anorexia nervosa and not taking medications 
during the amenorrhea (e.g., oral contraceptives, hormones, gonadotropin 
releasing hormone, anti-estrogens, selective estrogen receptor modulators 
(SERMs), or chemotherapy that induced amenorrhea)
Participation in the Study
Women of child-bearing potential and not of child-bearing potential may participate in this 
study.
Women of child-bearing potential must test negative for pregnancy prior to initiation of 
treatment as indicated by a negative urine pregnancy test at the screening visit.
Women of child-bearing potential who are completely abstinent or in a same sex relationship, as 
part of their preferred and usual lifestyle, must agree to either remain abstinent or stay in a same 
sex relationship without sexual relationships with males.

CONFIDENTIAL
Protocol J2X-MC-PYAJ
48
All other women of child-bearing potential must agree to use 2 forms of effective contraception, 
where at least one form is highly effective (less than 1% failure rate), for the entirety of the 
study.
Abstinence or contraception must continue for 90 days after the last dose of intervention.
Acceptable Methods of Contraception
Highly effective methods of contraception (less than 1% failure rate) comprise but are not 
limited to

combination oral contraceptives

implanted contraceptives, or 

intrauterine devices. 
Effective methods of contraception comprise but are not limited to diaphragms with spermicide 
or cervical sponges.
Not Acceptable Methods of Contraception
Use of male and female condoms as a double barrier method is not considered acceptable due to 
the high failure rate when these barrier methods are combined.
Barrier protection methods without concomitant use of a spermicide are not an effective or 
acceptable method of contraception.
Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods), 
declaration of abstinence just for the duration of a trial, and withdrawal are not acceptable 
methods of contraception.
Men
Men, regardless of their fertility status, must agree to either remain abstinent (if this is their 
preferred and usual lifestyle) or use condoms as well as one additional highly effective method 
of contraception (less than 1% failure rate) or effective method of contraception with non-
pregnant women of child bearing potential partners for the duration of the study and until their 
plasma concentrations are below the level that could result in a relevant potential exposure to a 
possible fetus, predicted to be 90 days after the last dose.
Men with pregnant partners should use condoms during intercourse for the duration of the study 
and until the end of estimated relevant potential exposure to the fetus, predicted to be 90 days 
after the last dose.
Acceptable Methods of Contraception
Highly effective methods of contraception (less than 1% failure rate) comprise, but are not 
limited to

combination oral contraceptives

implanted contraceptives, or 

intrauterine devices. 

CONFIDENTIAL
Protocol J2X-MC-PYAJ
49
Effective methods of contraception comprise but are not limited to diaphragms with spermicide 
or cervical sponges.
Men and their partners may choose to use a double-barrier method of contraception that must 
include use of a spermicide.
Other Guidance
Men should refrain from sperm donation for the duration of the study and until their plasma 
concentrations are below the level that could result in a relevant potential exposure to a possible 
fetus, predicted to be 90 days after the last dose. 
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 study intervention.
After obtaining the necessary signed informed consent and assent (if applicable) 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, this 
information will include a follow-up of at least 5 half-lives after last exposure or birth. Any 
termination of the pregnancy will be reported including fetal status (presence or absence of 
anomalies) and 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. The initial 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, this information will include a follow-up of at least 5 half-
lives after last exposure or birth. Any termination of pregnancy will be reported, including fetal 
status (presence or absence of anomalies) or indication for the procedure.
While pregnancy itself is not considered to be an AE or SAE, any pregnancy complication or 
elective termination of a pregnancy for medical reasons will be reported as an AE or SAE. 
A spontaneous abortion (occurring at <20 weeks gestational age) or still birth (occurring at >20
weeks gestational age) is always considered to be an SAE and will be reported as such. 
Any post-study pregnancy-related SAE considered reasonably related to the study intervention 
by the investigator will be reported to the sponsor as described in Section 8.3.4. 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.
