Study Design
1.2.1.
Study Design
This Phase 2, open-label, multicenter, multi-arm study is evaluating magrolimab + docetaxel 
combination therapy for patients with solid tumors. This study will consist of the following 
Safety Run-in Cohort:
•
Safety Run-in Cohort 1: magrolimab + docetaxel combination in patients with solid tumors 
(mNSCLC, mUC, and mSCLC)
After completion of Safety Run-in Cohort 1, Phase 2 Cohort 1 will occur with Cohort 1a, 1b, and 
1c for mNSCLC, mUC, and mSCLC, respectively. 
Up to approximately 114 patients may be enrolled in the study, with up to approximately 
18 patients in Safety Run-in Cohort 1 and 96 patients in Phase 2 Cohort 1. 
The study schematic is presented in Figure 1-1.

1.2.2.
Safety Run-in Cohort 1
A dose‑limiting toxicity (DLT) evaluation period of 1 cycle (21 days) will occur. After 6 patients 
have completed the DLT evaluation period, decision will be made on further expansion or dose 
de-escalation.
Even though no dose-dependent toxicities have been observed with magrolimab, in order to 
preserve the efficacious doses of the combination partner drugs, dose de-escalation will take 
place for magrolimab.
Dose de-escalation decisions will be made as follows:
•
If 2 or fewer of 6 DLT-evaluable patients experience a DLT in Cycle 1, enrollment into 
Phase 2 Cohort 1 will begin at this dose level as the recommended Phase 2 dose.
•
If more than 2 patients experience at least 1 DLT during Cycle 1, enrollment at the current 
dose level will immediately stop and dose de-escalation will occur. Up to another 6 patients 
will then be enrolled and evaluated at a lower dose level in the same manner.
1.2.3.
Phase 2 Cohort 1
Once Safety Run-in Cohort 1 is completed and the recommended dose for Phase 2 Cohort 1 is 
determined, the sponsor will open Phase 2 Cohort 1. Phase 2 Cohort 1 will treat up to 30 patients 
with mNSCLC (Phase 2 Cohort 1a), up to 26 patients with mUC (Phase 2 Cohort 1b), and up to 
40 patients with mSCLC (Phase 2 Cohort 1c) to evaluate efficacy.
1.2.4.

Sample Size and Power
Table 1-3 presents the sample size calculations. For Phase 2 Cohort 1, a sample size of 
30 patients in the mNSCLC cohort and 40 patients for the mSCLC cohort were calculated using 
one sample proportion test. The sample size of 26 patients for the mUC cohort was calculated 
using exact method instead of one sample test due to smaller sample size.

The null ORR for each of the respective tumor cohorts are based on historical taxane efficacy 
data in the second line setting {Bellmunt 2017, Rittmeyer 2017, Smit 1998}. Power calculations 
were performed using EAST 6.5 and nQuery 8.0.

TYPE OF ANALYSIS
2.1.
Dose Determination Analysis
For the purposes of making any dose de-escalation decisions for Safety Run-in Cohort 1, dose 
determination analyses of relevant safety data focusing on DLTs and overall safety profile was 
conducted by the sponsor after all patients had completed required dosing cycles (21 days) and 
the follow-up period as defined in Section 1.2.2. Dose Determination Analyses has been 
completed and is not within the scope of this SAP.
2.2.
Informal Interim Analyses
No formal interim efficacy analysis, which may lead to early termination for efficacy or futility, 
is planned. 
For the purpose of potential Phase 3 planning, informal interim analyses may be conducted per 
cohort after at least 20 patients enrolled in each tumor type (i.e., including applicable patients 
from the combined Safety Run-in) and have been followed up for approximately 19 weeks. 
2.3.
Primary Analysis 
For each of the subcohorts in Phase 2 Cohort 1, the primary analysis of ORR will be conducted 
approximately 6 months after the last patient is enrolled, outstanding data queries have been 
resolved or adjudicated as unresolvable, and the data have been cleaned and finalized for the 
analysis.
2.4.
Final Analysis
The final analysis may be performed after all patients have completed the study or discontinued 
early, outstanding data queries have been resolved or adjudicated as unresolvable, and the data 
have been cleaned and finalized.

GENERAL CONSIDERATIONS FOR DATA ANALYSES
Analysis results will be presented using descriptive statistics. For categorical variables, the 
number and percentage of patients in each category will be presented; for continuous variables, 
the number of patients (n), mean, standard deviation (StD) or standard error (SE), median, first 
quartile (Q1), third quartile (Q3), minimum, and maximum will be presented.
3.1.
Analysis Sets
For each analysis set, the number and percentage of patients eligible for inclusion, as well as the 
number and percentage of patients who were excluded and the reasons for their exclusion, will 
be summarized by cohort (Safety run-in cohort 1, Phase 2 cohort 1a, 1b, 1c, respectively).
A listing of reasons for exclusion from analysis sets will be provided by patient.
3.1.1.
All Enrolled Analysis Set
All Enrolled Analysis Set includes all patients who received a study subject identification 
number in the study after screening. 
3.1.2.
Modified ITT Analysis Set
The modified ITT Analysis Set (mITT) includes all enrolled patients who took at least 1 dose of 
any study drug. This is the primary analysis set for efficacy analyses of Phase 2 Cohort 1a, 1b 
and 1c, respectively.
3.1.3.
Safety Analysis Set
The Safety Analysis Set includes all patients who took at least 1 dose of any study drug. This is 
the primary analysis set for safety analysis (except for DLTs) of both Safety Run-in Cohort 1 and 
Phase 2 Cohort 1a, 1b, 1c, respectively.
3.1.4.
Dose-Limiting Toxicity (DLT) Evaluable Analysis Set
For Safety Run-in Cohort 1, the primary analysis set for the primary DLT analysis is the DLT 
Evaluable Analysis Set, defined as all patients who meet 1 of the following criteria in the DLT 
evaluable period (defined as 21 days of the first dosing cycle):
•
The patient experienced a DLT at any time after initiation of the first infusion of magrolimab.
•
The patient did not experience a DLT and completed at least 2 infusions of magrolimab 
(21-day cycle) and at least 1 dose of docetaxel in Safety Run-in Cohort 1.
For the 2nd criteria above, the 2 doses of magrolimab and 1 dose of docetaxel are infused within 
the 21-day cycle and patient is on study for at least 21 days after the first dose in Safety Run-in 
Cohort 1.

3.1.5.
Pharmacokinetic Analysis Set
The PK analysis will be conducted on the PK Analysis Set, defined as all patients who received 
any amount of magrolimab and have at least 1 measurable posttreatment serum concentration of 
magrolimab.
3.1.6.
Immunogenicity Analysis Set
The immunogenicity analysis will be conducted on the Immunogenicity Analysis Set, defined as 
all patients who received any amount of magrolimab and have at least 1 evaluable 
anti-magrolimab antibody test result.
3.1.7.
Biomarker Analysis Set
The biomarker analysis will be conducted on the Biomarker Analysis Set, defined as all patients 
who received any study drug and have at least 1 evaluable biomarker measurement available.
3.2.
Subject Grouping
For primary analyses and final analysis based on the mITT or Safety Analysis Set, patients will 
be grouped according to the cohort they were enrolled in: Safety Run-in Cohort 1, Phase 2 
Cohort 1a (mNSCLC), Phase 2 cohort 1b (mUC), and Phase 2 cohort 1c (mSCLC).
For informal interim analysis based on the mITT or Safety Analysis Set, patients will be grouped 
according to the tumor type at enrollment as follows:
•
Safety Run-in cohort 1 with tumor type mNSCLC + Phase 2 cohort 1a (mNSCLC) 
•
Safety Run-in cohort 1 with tumor type mUC + Phase 2 cohort 1b (mUC) 
•
Safety Run-in cohort 1 with tumor type mSCLC + Phase 2 cohort 1c (mSCLC) 
Here the tumor type from safety run-in cohort 1 is determined by the type of cancer from 
medical history as collected in CRF. 
3.3.
Strata and Covariates
This study does not have randomization so no randomization strata is defined. 
No covariates will be included in efficacy and safety analyses.
3.4.
Examination of Subject Subgroups
There are no prespecified patient subgroupings for efficacy and safety analyses.

Missing Data and Outliers
3.6.1.
Missing Data
In general, missing data will not be imputed unless methods for handling missing data are 
specified. 
3.6.2.
Outliers
Outliers will be identified during the data management and data analysis process, but no 
sensitivity analyses will be conducted. All data will be included in the data analysis.
3.7.
Data Handling Conventions and Transformations
The following conventions will be used for the imputation of date of birth when it is partially 
missing or not collected:
•
If only year of birth is collected, then “01 July” will be imputed as the day and month of birth
•
If year of birth is missing, then date of birth will not be imputed.
In general, age collected at the Study Day 1 (in years) will be used for analyses and presented in 
listings. If age at Day 1 is not available for a subject, then age derived based on date of birth and 
the date of Study Day 1 will be used instead. If an enrolled subject was not dosed with any study 
drug, the enrollment date will be used instead of the Day 1 visit date. For screen failures or patients 
who are not enrolled, the date the first informed consent was signed will be used for the age 
derivation. Age required for longitudinal and temporal calculations and analyses (eg, estimates of 
creatinine clearance, age at date of AE) will be based on age derived from date of birth and the 
date of the measurement or event, unless otherwise specified.
Non-PK data that are continuous in nature but are less than the lower limit of quantitation (LOQ) 
or above the upper LOQ will be imputed as follows:
•
A value that is 1 unit less than the LOQ will be used to calculate descriptive statistics if the 
datum is reported in the form of “< x” (where x is considered the LOQ). For example, if the 
values are reported as < 50 and < 5.0, values of 49 and 4.9, respectively, will be used to 
calculate summary statistics. An exception to this rule is any value reported as < 1 or < 
0.1,etc. For values reported as < 1 or < 0.1, a value of 0.9 or 0.09, respectively, will be used 
to calculate summary statistics.
•
A value that is 1 unit above the LOQ will be used to calculate descriptive statistics if the 
datum is reported in the form of “> x” (where x is considered the LOQ). Values with decimal 
points will follow the same logic as above.
•
The lower or upper LOQ will be used to calculate descriptive statistics if the datum is 
reported in the form of “≤ x” or “≥ x” (where x is considered the lower or upper LOQ, 
respectively).

If methods based on the assumption that the data are normally distributed are not adequate, 
analyses may be performed on transformed data or nonparametric analysis methods may be used, 
as appropriate.
PK Data Handling
Natural logarithmic transformation will be used for analyzing non-BLQ concentrations and PK 
parameters. Concentration values that are below the limit of quantitation (BLQ) will be presented 
as “BLQ” in the concentration data listing. Values that are BLQ will be treated as 0 at predose 
and postdose time points for summary purposes. The number of samples will be summarized to 
reflect the actual number of samples assessed at that time point.
At predose, if all concentration values are BLQ, then the mean, and order statistics (minimum, 
Q1, median, Q3, and maximum) will be displayed as 0 and the rest of the summary statistics (ie, 
SD and CV) will be missing. If any values are non-BLQ, then the number of samples, order 
statistics, and all summary statistics will be displayed. 
At any given postdose time point, if more than one-third of the participants have a concentration 
value of BLQ, then only the number of samples and order statistics will be displayed; otherwise, 
order statistics and summary statistics will be displayed.
The following conventions will be used for the presentation of order statistics for postdose time 
points: 
•
If at least 1 participant has a concentration value of BLQ for the time point, the minimum 
value will be displayed as “BLQ.”
•
If more than 25% of the participants have a concentration data value of BLQ for a given time 
point, the minimum and Q1 values will be displayed as “BLQ.” 
•
If more than 50% of the participants have a concentration data value of BLQ for a given time 
point, the minimum, Q1, and median values will be displayed as “BLQ.” 
•
If more than 75% of the participants have a concentration data value of BLQ for a given time 
point, the minimum, Q1, median, and Q3 values will be displayed as “BLQ.” 
•
If all participants have concentration data values of BLQ for a given time point, all order 
statistics (minimum, Q1, median, Q3, and maximum) will be displayed as “BLQ.”
PK parameters that are BLQ will be excluded before log transformation or statistical model fitting 
and displayed as described above.

3.8.1.
Definition of Study Day
Study day will be calculated from the first dosing date of any study drug, which is the date of the 
first dose of magrolimab or the combination drug, whichever occurs first and derived as follows:
•
For postdose study days: Assessment Date – First Dosing Date + 1
•
For days prior to the first dose: Assessment Date – First Dosing Date
Therefore, study day 1 is the day of first dose of any study drug administration. If the subject is 
enrolled but not dosed, the enrollment date will be study day 1.
3.8.2.
Analysis Visit Windows
Subject visits might not occur on protocol-specified days. Therefore, for the purpose of analysis, 
observations will be assigned to analysis windows.
The analysis windows for lab assessments are provided in Table 3-1. Post-infusion lab 
assessments for hemoglobin and hematocrit will use nominal visit and will be excluded when 
applying Table 3-1. Analyses windows will be applied to summary tables of lab results by visits 
and change from baseline if applicable.

Selection of Data in the Event of Multiple Records in an Analysis Visit 
Window
If multiple valid / nonmissing measurements exist in an analysis window, records will be chosen 
based on the following rules if a single value is needed:
•
For baseline, the last nonmissing value on or prior to the first dosing date of study drug will 
be selected, unless specified differently. If there are multiple records with the same time or 
no time recorded on the same day, the baseline value will be the average of the 
measurements for continuous data, or the measurement with the worst severity for 
categorical data.
•
For postbaseline values:
The record closest to the nominal day for that visit will be selected.
If there are 2 records that are equidistant from the nominal day, the later record will be 
selected.
If there is more than 1 record on the selected day, the average will be taken for 
continuous data and the worst severity will be taken for categorical data, unless otherwise 
specified.
3.9.

interruption, dose delayed or not administered) and reasons for each study drug (Magrolimab and 
Docetaxel) by cohort.
5.2.1.
Duration of Exposure
Total duration of exposure to each study drug (Magrolimab and Docetaxel) will be defined for a 
subject as last dosing date minus first dosing date plus 1 day, regardless of any temporary 
interruptions in study drug administration, and will be expressed in weeks using up to 1 decimal 
place (e.g., 4.5 weeks).

patients exposed for at least the following time periods: 1 day, 3 weeks, 6 weeks, 9 weeks, 
18 weeks, and 27 weeks, etc.
5.2.2.
Relative Dose Intensity
Relative dose intensity (RDI) is the percentage of the total amount of study drug administered 
relative to the total amount of study drug expected to be administered during a patient’s actual 
on-treatment period based on the study drug regimen. 
Summary of relative dose intensity of magrolimab will be expressed as a percentage using the 
following formula:
𝑅𝑒𝑙𝑎𝑡𝑖𝑣𝑒 𝑑𝑜𝑠𝑒 𝑖𝑛𝑡𝑒𝑛𝑠𝑖𝑡𝑦 (%) =

Cumulative dosage (mg/kg for Magrolimab or mg/m2 for Docetaxel) received for each subject is 
defined as the sum of all delivered dosages of all infusions the subject received. Delivered 
dosage will be calculated by the actual dose received (mg) as collected in CRF devided by the 
subjects’s weight (for Magrolimab) or BSA (for Docetaxel) collected on or before that visit. 
Total assigned dosage (mg/kg or mg/m2) for each subject is defined as the sum of the assigned 
dosage per protocol specified dose level and dosing schedule.
For each study drug, descriptive statistics for the relative dose intensity with the number and 
percentage of patients belonging to relative dose intensity categories (eg, < 75%, ≥ 75 to < 90%, 
≥ 90%) will be provided by cohort for the Safety Analysis Set.

Medications collected at screening and during the study will be coded using the current version 
of the World Health Organization (WHO) Drug dictionary.
5.5.1.
Prior Medications
Prior medications are defined as any medications taken before a patient took the first study drug.
Prior medications will be summarized by Anatomical Therapeutic Chemical (ATC) drug class 
Level 2 preferred name using the number and percentage of subjects by cohort and treatment 
group. A subject reporting the same medication more than once will be counted only once when 
calculating the number and percentage of subjects who received that medication. The summary 
will be ordered alphabetically by ATC medical class and then by preferred term in order of 
descending overall frequency within each ATC medical class. For drugs with the same 
frequency, sorting will be done alphabetically.
For the purposes of analysis, any medication with a start date prior to the first dosing date of 
study drug will be included in the prior medication summary regardless of when the stop date is. 
If a partial start date is entered the medication will be considered prior unless the month and year 
(if day is missing) or year (if day and month are missing) of the start date are after the first 
dosing date. Medications with a completely missing start date will be included in the prior 
medication summary, unless otherwise specified.

Concomitant medications are defined as medications taken while a patient took study treatment. 
Use of concomitant medications will be summarized by Anatomical Therapeutic Chemical 
(ATC) drug class Level 2 and preferred name using the number and percentage of patients for 
each cohort. A patient reporting the same medication more than once within each ATC drug 
class will be counted only once when calculating the number and percentage of patients who 
received that medication. Medications may appear under multiple ATC drug classes. The 
summary will be ordered alphabetically by ATC medical class and then by preferred term in 
descending overall frequency within each ATC medical class. For drugs with the same 
frequency, sorting will be done alphabetically.
For the purposes of analysis, any medications with a start date prior to or on the first dosing date 
of study treatment and continued to be taken after the first dosing date, or started after the first 
dosing date but prior to or on the 30 days after last dosing date of study treatment will be 
considered concomitant medications. Medications started and stopped on the same day as the 
first dosing date or the last dosing date of study treatment will also be considered concomitant. 
Medications with a stop date prior to the date of first dosing date of study treatment or a start 
date after the last dosing date of study treatment plus 30 days will be excluded from the 
concomitant medication summary. Medications with partially or completely missing start and 
stop dates will be included in the concomitant medication summary, unless the partial missing 
date suggested otherwise. 
Summaries will be based on the Safety Analysis Set. 
All concomitant medications will be provided in a by-patient listing sorted by subject ID number 
and administration date in chronological order.

EFFICACY ANALYSES
In general, summary of efficacy endpoints in this section will be based on mITT Analyses Set for 
each of the phase 2 cohort 1a, 1b and 1c, unless specified otherwise. Listing will be based on All 
Enrolled Analysis Set. Safety run-in cohort 1 subjects will only be listed for efficacy related 
endpoints.
6.1.
Primary Efficacy Endpoints
6.1.1.
Definition of the Primary Efficacy Endpoints
The primary efficacy endpoint of this study is objective response rate (ORR) defined as the 
proportion of patients who achieve the best overall response of complete response (CR) or partial 
response (PR) that is confirmed at least 4 weeks after initial documentation of response. The 
responses are measured by response evaluation criteria in solid tumors (RECIST), Version 1.1, 
as determined by investigator assessment (Phase 2 cohorts 1a, 1b, and 1c). Tumor response 
assessments after the date of patients receiving new anticancer therapy will be excluded from the 
analysis. Patients who do not have baseline or on-study response status assessment, or who 
received subsequent anticancer therapy prior to achieving CR or PR, will be considered as non-
responders.
6.1.2.
Analysis of the Primary Efficacy Endpoint
For each of Phase 2 cohorts 1a, 1b and 1c, the primary analysis of ORR will be conducted 
approximately 6 months after the last patient is enrolled. ORR along with the 2-sided 95% exact 
confidence interval (CI) of ORR based on Clopper-Pearson method will be provided for each 
cohort. 
6.1.3.
Sensitivity Analysis of the Primary Efficacy Endpoint
There is no sensitivity analysis is planned.
6.2.
Secondary Efficacy Endpoints
6.2.1.
Definition of Secondary Efficacy Endpoints
Progression-Free Survival (PFS)
PFS is defined as the interval from the first dosing date of any study drug to the earlier date of 
the first documentation of objective disease progression by investigator assessment per RECIST, 
Version 1.1, or death from any cause.

Page 26
06 March 2024
Duration of Response (DOR) 
DOR is defined for confirmed responders as duration of time from the date of initial response 
(first confirmed CR or PR) to the date of first documentation of disease progression per RECIST, 
Version 1.1, or the date of death due to any cause, whichever occurs first.
DOR = Date of disease progression/death or censoring – Date of first confirmed CR/PR + 1.
Date of initial response is the date of first response achieved and then confirmed by a subsequent 
disease assessment conducted prior to or at the initiation of the next line of subsequent anticancer 
therapy. 
Date of disease progression (PD) used to calculate DOR is the first PD date prior to or on the 
date of initiation of subsequent anticancer therapy.  
Overall Survival (OS) 
OS is defined as the interval from first dosing date of any study drug to death from any cause. 
For patients who were not known to have died at the time of the analysis, OS data will be 
censored at the last date that they were known to be alive. In the event that the patient has 
withdrawn consent, the vital status of the patient can be obtained by site personnel from publicly 
available resources under applicable local laws. 
6.2.2.
Analysis Methods for Secondary Efficacy Endpoints
Analysis of PFS, OS and DOR (confirmed responders only) will be performed using the Kaplan-
Meier method for the mITT Analysis Set. Medians, Q1, Q3, and the proportion of patients who 
are progression-free (for PFS only) will be provided along with corresponding 95% CIs 
calculated by the Brookmeyer and Crowley method with log-log transformation for each of the 
Phase 2 cohorts. Kaplan-Meier curves will be provided by each of the Phase 2 cohorts. 
Censoring rules for PFS and DOR are listed in Table 6-1.

SAFETY ANALYSES
In general, safety analysis will be performed in the Safety Analysis Set for each cohort (Safety 
run-in cohort 1, Phase 2 cohort 1a, 1b and 1c respectively) and listings will be provided on the 
All Enrolled analysis set unless specified otherwise. Analysis of DLT was performed using the 
DLT evaluable analysis set for Safety Run-in evaluations which is not under the scope of this 
SAP.
7.1.
Adverse Events and Deaths
7.1.1.
Adverse Event Dictionary
Clinical and laboratory adverse events (AEs) will be coded using the current version of Medical 
Dictionary for Regulatory Activities (MedDRA). 
7.1.2.
Adverse Event Severity
Adverse events are graded by the investigator as Grade 1, 2, 3, 4, or 5 according to CTCAE 
Version 5.0. 
7.1.3.
Relationship of Adverse Events to Study Treatment
Related AEs are those for which the investigator selected “Related” on the AE CRF to the 
question of “Related to Study Treatment.” Summary of relationship will also be applied based on 
“Related to Study Treatment Magrolimab” and “Related to Study Treatment Docetaxel” 
separately. 
Relatedness will always default to the investigator’s choice, not that of the medical monitor. 
Events for which the investigator did not record relationship to study drug will be considered 
related to study drug for summary purposes. However, by-patient data listings will show the 
relationship as missing.
7.1.4.
Serious Adverse Events 
Serious adverse events (SAEs) will be identified and captured as SAEs if the AEs met the 
definitions of SAEs that were specified in the study protocol. SAEs captured and stored in the 
clinical database will be reconciled with the SAE database from the Gilead Global Patient Safety 
Department before data finalization.
7.1.5.
Treatment-Emergent Adverse Events 
7.1.5.1.
Definition of Treatment-Emergent Adverse Events
Treatment-emergent adverse events (TEAEs) are defined as any events not present prior to the 
study treatment, or any events already present but worsening in either intensity or frequency 
following exposure to the study treatment. 


Magrolimab
GS-US-548-5918

Page 30
06 March 2024
The TEAE reporting period is defined as the period from the date of the first dose of study 
treatment up to 30 days after the date of the last dose of study treatment or the day before 
initiation of subsequent antineoplastic therapy, whichever comes first. 
If the AE onset date is on or before the last dose date, the AE is considered as TEAE, regardless 
of the initiation of subsequent anti-cancer therapy.
7.1.5.2.
Missing or incomplete Dates
If there was a missing or incomplete date for the start date or stop date of an AE, the most 
conservative approach was used for analysis. 
If the onset date of the AE is incomplete and the AE stop date is not prior to the first dosing date 
of study drug, then the month and year (or year alone if month is not recorded) of onset 
determine whether an AE is treatment emergent. The event is considered treatment emergent if 
both of the following 2 criteria are met:
•
The AE onset date is the same as or after the month and year (or year alone if month is not 
recorded) of the first dosing date of any study drug, and
•
The AE onset date is the same as or before the month and year (or year alone if month is not 
recorded) of the date corresponding to the cutoff date of TEAE period, which is defined as 
the 30 days after the any study drug last dosing date or the day before the initiation of new 
anticancer therapy (whichever is earlier)
An AE with completely missing onset and stop dates, or with the onset date missing and the stop 
date later than the first dosing date of study drug, will be considered to be treatment emergent. 
In addition, an AE with the onset date missing and incomplete stop date with the same month 
and year (or year alone if month is not recorded) or later as the first dosing date of study drug 
will be considered treatment emergent.
In case when the AE onset date is incomplete and needs to be imputed, the following algorithm 
will be followed:
•
If the day is missing but the month and year are available, then the imputed day will be the 
first dosing date if they have the same month and year, or the first day of the month 
otherwise.
•
If the day and month are missing but year is available, then the imputed day and month will 
be the first dosing date if they have the same year, or 01Jan otherwise.

Laboratory Evaluations
Laboratory data collected during the study will be analyzed and summarized using both 
quantitative and qualitative methods. Summaries of laboratory data will be provided for the 
Safety Analysis Set and will include data collected up to 30 days plus the last dose date OR the 
initiation of subsequent anti-cancer therapy. If the lab data collected on or before the last dose 
date, data will be included regardless of the initiation of subsequent anti-cancer therapy. The 
analysis will be based on values reported in conventional units. When values are below the LOQ, 
they will be listed as such, and the closest imputed value will be used for the purpose of 
calculating summary statistics as specified in Section 3.7.
A by-patient listing for laboratory test results will be provided by subject ID number and visit in 
chronological order for hematology and serum chemistry separately. Values falling outside of the 
relevant reference range and/or having a severity grade of 1 or higher on the CTCAE severity 
grade will be flagged in the data listings, as appropriate.
No formal statistical testing is planned.
7.2.1.
Summaries of Numeric Laboratory Results
Descriptive statistics will be provided by cohort for selected laboratory test specified in the study 
protocol as follows:
•
Baseline values 
•
Postbaseline maximum value
•
Postbaseline minimum value

Plots of lab parameters may include (but not limited to) hemoglobin, hematocrit, platelet, and 
absolute neutrophil counts over time.
In the case of multiple values in an analysis window, data will be selected for analysis as 
described in Section 3.8.3.
7.2.2.
Graded Laboratory Values
The CTCAE Version 5.0 will be used to assign toxicity grades (0 to 4) to laboratory results for 
analysis. Grade 0 includes all values that do not meet the criteria for an abnormality of at least 
Grade 1. For laboratory tests with criteria for both increased and decreased levels, analyses for 
each direction (i.e., increased, decreased) will be presented separately. 
7.2.2.1.
Treatment-Emergent Laboratory Abnormalities
Treatment-emergent laboratory abnormalities are defined as values that increase at least 
1 toxicity grade from baseline at any postbaseline time point, up to and including the date of last 
dose of study drug plus 30 days and prior to the day of initiation of subsequent anti-cancer 
therapy. If the relevant postbaseline lab is assessed on or before the last dose date, the laboratory 
abnormality is considered as treatment-emergent laboratory abnormality, regardless of the 
initiation of subsequent anti-cancer therapy. If the relevant baseline laboratory value is missing, 
any abnormality of at least Grade 1 observed within the time frame specified above will be 
considered treatment emergent.
7.2.2.2.
Treatment-Emergent Marked Laboratory Abnormalities
Treatment-emergent marked laboratory abnormalities are defined as values that increase from 
baseline by at least 3 toxicity grades at any postbaseline time point up to and including the date 
of last dose of study drug plus 30 days and prior to the day of initiation of subsequent anti-cancer 
therapy. If the relevant postbaseline lab (with at least 3 toxicity grades increasing from baseline) 
is assessed on or before the last dose date, the laboratory abnormality is considered as treatment-
emergent marked laboratory abnormality, regardless of the initiation of subsequent anti-cancer 
therapy. If the relevant baseline laboratory value is missing, any Grade 3 or 4 values observed 
within the timeframe specified above will be considered treatment-emergent marked 
abnormalities.
7.2.2.3.
Summaries of Laboratory Abnormalities
The following summaries (number and percentage of patients) for treatment-emergent (TE) 
laboratory abnormalities will be provided by lab test by cohort. Patients will be categorized 
according to the most severe postbaseline abnormality grade for a given lab test:

For all summaries of laboratory abnormalities, the denominator is the number of patients in the 
correponding nonmissing postbaseline laboratory values up to 30 days after the last dosing date 
or the day before initiation of new anticancer therapy, whichever is earlier. 
By-patients listings of treatment-emergent Grade 3 or 4 laboratory abnormalities and treatment 
emergent marked laboratory abnormalities will be provided by subject ID number and visit in 
chronological order. This listing will include all test results that were collected throughout the 
study for the lab test of interest, with all applicable severity grades displayed. 
By-patient listing for post-infusion hematology will also be provided. Laboratory abnormalities 
that occur before the first dose of study drug or after the patient has been discontinued from 
treatment for at least 30 days will also be included in a data listing.
7.2.3.
Liver-related Laboratory Evaluations
Liver-related abnormalities after the first dose of any study drug will be examined and 
summarized by cohort using the number and percentage of patients who were reported to have 
the following laboratory test values for postbaseline measurements:
•
Aspartate aminotransferase (AST): >= 3 times of the upper limit of reference range (ULN)
•
Alanine aminotransferase (ALT): >= 3 x ULN
•
AST or ALT: >= 3 x ULN
•
Total bilirubin: > 2 x ULN
•
AST or ALT >= 3 x ULN and total bilirubin > 2 x ULN
•
AST or ALT >= 3 x ULN and total bilirubin > 2 x ULN and alkaline phosphatase (ALP) 
< 2 x ULN
The summary will include data from all postbaseline visits up to 30 days after the last dose of 
study drug or the day before initiation of new anticancer therapy, whichever is earlier. For 
individual laboratory tests, patients will be counted once based on the most severe postbaseline 
values. For the composite endpoints of AST or ALT and total bilirubin and ALP, patients will be 
counted once when the criteria are met at the same postbaseline visit date. The denominator is 
the number of patients in the Safety Analysis Set who have at least one postbaseline visit, at 
which all the relevant tests are nonmissing at the same postbaseline visit date.

PHARMACOKINETIC (PK) AND IMMUNOGENICITY 
ANALYSES
9.1.
PK Analysis
The PK Analysis Set will be used for summaries of PK concentration of magrolimab versus time. 
Serum concentrations will be listed and summarized for magrolimab using descriptive statistics 
by sampling timepoint and treatment. Graphical plots of individual serum concentration versus 
time and mean concentration versus time by treatment will be generated. PK data from this study 
might be combined with PK data from other Magrolimab studies and analyzed using a 
population PK model. Such an analysis would be reported separately.
9.2.
Immunogenicity analysis
Serum samples for antidrug antibody (ADA) assessments will be conducted utilizing a tiered 
approach (screen, confirmatory and titer), and ADA data will be collected at scheduled visits 
shown in the protocol. ADA result from each sample will be reported as either positive or 
negative. If the sample is positive, the ADA titer will be reported as well. In addition, the 
presence of neutralizing antibody (nAb) will be tested for all ADA positive samples using a 
ligand-binding assay. The nAb results will be reported as positive or negative. 
Patients for ADA prevalence are defined as patients who had at least one positive ADA sample 
at any time, including baseline and post-baseline, in Immunogenicity Analysis Set.
Patients for ADA incidence are defined as patients with at least one baseline ADA sample and at 
least one post-treatment ADA sample in Immunogenicity Analysis Set. 
Patients for nAb prevalence are defined as patients who had at least one positive nAB sample at 
any time, including baseline and post-baseline, in Immunogenicity Analysis Set
Among patients for ADA incidence, patients who had Treatment-Induced ADA or Treatment-
Boosted ADA are categorized as ADA positive by incidence, where
•
Treatment-Induced ADA is defined as patients who had negative baseline ADA sample and 
at least one positive post-treatment ADA sample. 
•
Treatment-Boosted ADA is defined as patients who had positive baseline ADA sample and 
at least one positive post-treatment ADA sample and the (max titer of the post-treatment 
ADA) / (titer of baseline ADA) ≥ 4.
The remaining patients among patient for ADA incidence are ADA negative by incidence.

APPENDICES
13.1.
Appendix 1.
RECIST 1.1-based Assessments - Overall visit response
The RECIST tumour response data will be used to determine each patient’s visit response 
according to RECIST version 1.1. At each visit, patients will be assigned a RECIST 1.1 visit 
response of CR, PR, SD or PD, using the information from target lesions (TLs), non-target 
lesions (NTLs) and new lesions and depending on the status of their disease compared with 
baseline and previous assessments. If a patient has had a tumour assessment which cannot be 
evaluated, then the patient will be assigned a visit response of not evaluable (NE). For patients 
with no disease at baseline (i.e. no TLs and no NTLs), evaluation of overall visit responses will 
be based on absence/presence of new lesions.  If no TLs and no NTLs are recorded at a visit, 
both the TL and NTL visit response will be recorded as NA and the overall visit response will be 
no evidence of disease (NED). If a new lesion is observed then the overall visit response will be 
PD. Table 13-1 summarizes overall visit response given the visit responses from TL and NTL 
arecombined with new leision.
