Study Design: This is a Phase 3, randomized, double-blind, placebo-controlled study 
evaluating the safety and efficacy of magrolimab versus placebo in combination with 
venetoclax and azacitidine in newly diagnosed, previously untreated patients with AML who 
are ineligible for intensive chemotherapy. Approximately 432 patients will be randomized in 
1:1 ratio to receive either magrolimab + venetoclax + azacitidine (experimental arm) or placebo 
+ venetoclax + azacitidine (control arm). Randomization will be stratified by 3 factors:
•
age (< 75 years, ≥ 75 years)
•
genetic risk group (favorable/intermediate, adverse, unknown)
•
geographic region (United States [US], outside the US)

Cycle lengths are 28 days, and all patients will continue on study treatment until disease 
progression, relapse, loss of clinical benefit, unacceptable toxicities or other study treatment 
discontinuation criteria are met. Clinical benefit, as determined by the investigator, can include 
transfusion independence, adequate blood counts, symptomatic improvement, or other criteria 
as determined by the investigator.
Acute myeloid leukemia disease response assessment will be performed at the end of Cycle 1, 
Cycle 2, Cycle 4, Cycle 6, and every 3 cycles thereafter.
Patients will continue follow-up study visits unless they withdraw completely from the study.
All patients who discontinue study treatment for reasons other than death or start of new anti-
AML therapy (except maintenance and SCT) will participate in long-term follow-up for disease 
response unless the patient withdraws consent for such follow-up and withdraws completely 
from study.
In the event one or more components of the study treatment (magrolimab/placebo, azacitidine 
and/or venetoclax) are discontinued, the following combinations are permitted:
•
Magrolimab/placebo + azacitidine
•
Azacitidine (single agent)
•
Venetoclax + azacitidine
The following combinations are not permitted:
•
Magrolimab/placebo (single agent)
•
Venetoclax (single agent)
•
Magrolimab/placebo + venetoclax
If azacitidine is permanently discontinued, the patient must discontinue the remaining study 
treatment. Patients who discontinue study treatment but continue in a response or are achieving 
clinical benefit will continue to be followed on study for response assessments to ascertain 
relapse and for long-term survival.
All patients will be followed for survival until death, withdrawal of consent, loss to follow-up, 
completion of survival follow-up, or study termination by the sponsor, whichever occurs first. 
Duration of survival follow-up will be limited to 5 years from the end of treatment visit for 
each patient. If a patient discontinues study treatment and does not consent to continued follow-
up, the investigator must not access confidential records that require the patient’s consent. 
However, an investigator may consult public records to establish survival status. For any 
patient who dies during this follow-up period, the immediate cause of death must be reported to 
the sponsor.

Criteria for Evaluation:
Safety:
Safety will be evaluated by data including the incidence of AEs, clinical laboratory test 
findings, physical examination, and vital signs measurements. Adverse events will be graded 
using National Cancer Institute Common Terminology Criteria for Adverse Events 
(NCI CTCAE) Version 5.0.
Efficacy will be evaluated by OS, CR + CRh rate, CR rate, EFS, duration of CR + CRh, DCR, 
CR/CRhMRD- rate, CRMRD- rate, transfusion independence conversion rate, and GHS/QoL and 
physical functioning scale scores from EORTC QLQ-C30. Assessment of leukemia response in 
AML patients will be conducted using the European LeukemiaNet 2017 recommendations for 
AML and the 2003 and 2006 International Working Group criteria with modifications.
Pharmacokinetics: 
Magrolimab serum drug concentrations will be assessed in the magrolimab + venetoclax + 
azacitidine group based on the sample collection schedule until treatment discontinuation. 
Samples will also be collected for the detection of antidrug antibodies (ADA) against 
magrolimab. Presence of neutralizing antibodies to magrolimab will also be assessed in the 
ADA positive samples.

Statistical Methods:
Analysis Data Set 
The Intent-to-Treat (ITT) Analysis Set includes all randomized patients according to the 
treatment arm to which the patient is randomized, unless otherwise specified. This is the 
primary analysis set for efficacy analysis.
Safety Analysis Set
The Safety Analysis Set will include all patients who received at least 1 dose of any study 
treatment, with treatment assignments designated according to the actual treatment received.
Efficacy Analysis
Time-to-event endpoints, including OS, EFS, DCR, and duration of CR + CRh, will be 
summarized using Kaplan-Meier estimates, which include median and the proportion of event-
free patients at benchmark timepoints such as 6 months and 12 months. Kaplan-Meier plots will 
be provided.
Hypothesis testing will be performed on the ITT Analysis Set for OS and EFS using the log-
rank test stratified by randomization stratification factors. The hazard ratio (HR) with the 
corresponding 2-sided 95% CIs estimated using a Cox proportional hazard regression model 
stratified by randomization stratification factors will also be presented for OS and EFS.
Categorical endpoints including CR + CRh rate, CR rate, CR/CRhMRD- rate, CRMRD- rate, and 
transfusion independence conversion rate will be compared between the 2 arms using the 
Cochran-Mantel-Haenszel test stratified by randomization stratification factors. The point 
estimate of these rates and the corresponding 2-sided exact 95% CIs based on the exact 
Clopper-Pearson method will be provided for each treatment arm.
Time to first deterioration, with at least 1 threshold value deterioration from baseline or death, 
on the EORTC QLQ-C30 GHS/QoL scale and TTD on the EORTC QLQ-C30 physical 
functioning scale will be summarized using the Kaplan-Meier method. The log-rank test 
stratified by randomization stratification factors will be conducted for comparison between 
treatment arms, and the HR estimated using a Cox proportional hazard regression model 
stratified by randomization stratification factors will be provided.
To strongly control the overall type I error across the testing of primary and key secondary 
endpoints, a hierarchical testing strategy will be performed with a predefined order as listed in 
the protocol and the statistical analysis plan.
Safety Analysis
Safety will be assessed via AEs, clinical laboratory tests, and concomitant medications in the 
Safety Analysis Set by treatment arm. Information regarding study drug administration, study 
drug compliance, and other safety variables will also be summarized.

Interim Analysis
There are two planned interim analyses. 
The first interim futility analysis of OS will be performed when 121 deaths (40% of the 
expected deaths) have occurred, with a non-bounding futility boundary of HR = 1.1. 
The second interim analysis with O’Brien-Fleming boundary for efficacy will be performed 
when 227 deaths (75% of the expected 303 deaths) have occurred. If the null hypothesis of OS 
is not rejected in the interim analysis, the nonbinding futility test with a futility boundary of HR 
= 0.9 will be performed.
Primary Analysis
The primary analysis will be conducted when 303 death events occur.
Sample Size
The study will randomize approximately 432 patients in total into the control arm (placebo + 
venetoclax + azacitidine) and the experimental arm (magrolimab + venetoclax + azacitidine) at 
a 1:1 ratio, determined by formal hypothesis testing performed on the primary efficacy 
endpoint: OS, with family-wise Type I error controlled at 1-sided significance level of 0.025.
It is assumed that administration of magrolimab + venetoclax + azacitidine to study patients 
will result in a median OS of approximately 21 months, improved from a median OS of 
14.7 months in patients treated with placebo + venetoclax + azacitidine. This corresponds to an 
OS HR of 0.7. Assuming that the duration of OS is exponentially distributed in each of the 
2 arms, with an HR equal to 1 under the null hypothesis of no difference between the 
2 treatment arms, 303 events are needed to detect an HR of 0.7 with 86.4% power at a 1-sided 
significance level of 0.025 using a log-rank test. The design includes the first interim analysis 
with a futility test only when 40% of the information (121 deaths) is available, and the second 
interim analysis with a superiority test together with a futility test when 75% of the information 
(227 deaths) is available, and one primary analysis. For the second OS interim analysis and the 
OS primary analysis, the Lan-DeMets alpha spending function with O’Brien-Fleming stopping 
boundary will be used. The futility boundaries for two interim analyses are obtained using a 
Gamma beta-spending function with parameter -5.
With an accrual period of 19 months (with approximately 51% of the patients enrolled during 
the initial 12 months, and the remaining 49% of the patients enrolled during the last 7 months), 
24 months of follow up, and an annual 1.43% dropout rate (5% dropout chance by 43 months 
with time to dropout assuming exponentially distributed time-to-dropout), a total sample size of 
432 patients (216 patients per treatment group) is needed to observe the required 303 events.
This study will be conducted in accordance with the guidelines of Good Clinical Practice, 
including archiving of essential documents.

INTRODUCTION
1.1.
Background
1.1.1.
Acute Myeloid Leukemia
Acute myeloid leukemia (AML) is an aggressive clonal hematopoietic malignancy of myeloid 
cells in the blood and bone marrow leading to cytopenias and ultimately mortality via sequelae 
of bone marrow failure. The incidence of AML rises from 3 cases per 100,000 people in young 
adults to greater than 20 cases per 100,000 people in older adults. Initial treatment for AML is 
dependent on age and comorbidities. For patients < 60 years of age, 5-year overall survival (OS) 
is approximately 40% to 50% but is only 5% for patients > 60 years of age. For younger patients 
who are fit for intensive chemotherapy, induction chemotherapy with cytarabine and an 
anthracycline chemotherapy is the standard of care (SOC). In patients who are older and/or have 
comorbidities that preclude the use of induction chemotherapy, lower-intensity therapy is given 
with hypomethylating agents (HMAs) and low-dose cytarabine, with or without venetoclax, a 
Bcl-2 inhibitor. In all settings of AML, disease relapse is common despite an initial therapeutic 
response and is the most common reason for death.
1.1.2.
Patients Newly Diagnosed with AML Who Are Ineligible for Intensive 
Induction Chemotherapy
Patients who are older (approximately 75 years of age and older) or who have comorbidities 
precluding the use of intensive induction chemotherapy are treated with HMAs (ie, azacitidine or 
decitabine), low-dose cytarabine, and these agents in combination with venetoclax. In 2018, 
venetoclax in combination with HMAs or low-dose cytarabine was granted accelerated approval 
in the United States (US) for this population. This approval was based on results from multiple 
single-arm studies in which venetoclax demonstrated a complete remission (CR) rate of 37% in 
combination with azacitidine, 54% in combination with decitabine, and 21% in combination with 
low-dose cytarabine {VENCLEXTA 2020}. The median duration of CR was approximately 
4.8 to 6.0 months. Final results from a subsequent randomized Phase 3 trial that evaluated 
venetoclax + azacitidine versus azacitidine monotherapy in the same patient population 
demonstrated a significant benefit in median OS compared with the control arm (14.7 vs 
9.6 months, hazard ratio [HR] 0.66) {DiNardo 2020}. In addition, the CR/complete remission 
with incomplete hematologic recovery (CRi) rate was higher in the venetoclax + azacitidine arm 
than the azacitidine control arm (66.4% vs. 28.3%). These data have supported the use of 
venetoclax in combination with HMAs as the SOC for newly diagnosed patients with AML who 
are ineligible for intensive chemotherapy.

Magrolimab
1.2.1.
General Information
Cluster of differentiation 47 (CD47) is a key molecule mediating cancer cell evasion of innate 
immune surveillance. CD47 expression is a well-characterized mechanism by which cancer cells, 
including cancer stem cells, overcome phagocytosis due to intrinsic expression of prophagocytic

“eat me” signals {Jaiswal 2009, Majeti 2009}. The progression from normal cell to cancer cell 
involves changes in genes and gene expression that trigger programmed cell death and 
programmed cell removal {Chao 2012}. Many of the steps in cancer progression subvert the 
multiple mechanisms of programmed cell death, and the expression of the dominant 
antiphagocytic signal, CD47, may represent an important checkpoint {Chao 2012}. Increased 
CD47 expression was identified first on leukemic stem cells in human AML {Majeti 2009}, and 
since then it has been found that CD47 expression is increased on the surface of cancer cells in a 
diverse set of human tumor types.
In mouse xenograft models, CD47-blocking monoclonal antibodies (mAbs) inhibit human 
xenograft tumor growth and metastasis by enabling the phagocytosis and elimination of cancer 
cells from various hematologic malignancies and solid tumors {Chao 2011a, Chao 2010a, Chao 
2011b, Edris 2012, Kim 2012, Majeti 2009, Willingham 2012}. Binding of CD47 expressed by 
cancer cells to its ligand, signal regulatory protein alpha (SIRPα), expressed on phagocytes leads 
to inhibition of tumor cell phagocytosis. Thus, blockade of the CD47 SIRPα–signaling pathway 
by an anti-CD47 antibody leads to phagocytosis and elimination of tumor cells. Selective 
targeting of tumor cells by an anti-CD47 antibody is due to the presence of prophagocytic signals 
expressed mainly on tumor cells and not on normal cell counterparts {Chao 2010b}. In addition, 
the anti-CD47 antibody can induce an anti-cancer T-cell response through cross-presentation of 
tumor antigens by macrophage and antigen-presenting cells after tumor cell phagocytosis {Liu 
2015b, Tseng 2013}.
Magrolimab is a humanized anti-CD47 mAb that blocks the interaction of CD47 with its receptor 
and enables phagocytosis of human cancer cells {Liu 2015a}. The activity of magrolimab is 
primarily dependent on blocking CD47 binding to SIRPα and not on the recruitment of 
crystallizable fragment (Fc)–dependent effector functions, although the presence of the 
immunoglobulin G4 (IgG4) Fc domain is required for its full activity. For this reason, 
magrolimab was engineered with a human IgG4 isotype that is relatively inefficient at recruiting 
Fc-dependent effector functions that might enhance toxic effects on normal CD47-expressing 
cells {Liu 2015a}. Nonclinical studies using xenograft cancer models provide compelling 
evidence that magrolimab triggers phagocytosis and elimination of cancer cells from human 
solid tumors and hematologic malignancies. Based on this mechanism of action (MOA) and its 
potent nonclinical activity, magrolimab is being developed as a novel therapeutic candidate for 
solid tumors and hematologic malignancies.
The magrolimab program represents a novel strategy for the treatment of cancer and is the first 
therapeutic agent to target the CD47-SIRPα axis. Extensive nonclinical studies have 
demonstrated activity against both human solid tumors (breast, ovarian, pancreas, colon, 
leiomyosarcoma, bladder, prostate, and others) and hematologic malignancies (AML, acute 
lymphoblastic leukemia, non-Hodgkin lymphoma [NHL], myeloma, myelodysplastic syndrome 
[MDS], and others).
Magrolimab is being investigated as an anti-cancer therapeutic in several global ongoing clinical 
studies, as monotherapy or in combination with other therapeutics, for the treatment of NHL, 
AML, MDS, and several solid tumor types.

While magrolimab has single-agent preclinical and clinical activity, efficacy is best enhanced in 
combination with other anti-cancer agents. Preclinical and clinical studies have shown that 
magrolimab combinations with cytotoxic agents can enhance prophagocytic signals on tumor 
cells, which can lead to synergistic phagocytosis of cancer cells by macrophages. As such, 
magrolimab is being evaluated clinically in several combinations with cytotoxic agents including 
chemotherapy.
For further information on magrolimab, refer to the current investigator’s brochure (IB).
1.2.2.
Preclinical Pharmacology and Toxicology
The combination of magrolimab + azacitidine was evaluated in leukemic nonclinical models. 
Nonclinical synergy was observed based on the upregulation of prophagocytic signals (including 
calreticulin) on leukemic cells of a TP53 mutated cell line by azacitidine combined with 
blockade of the antiphagocytic signal CD47 with magrolimab {Feng 2018}. 
Magrolimab + azacitidine led to synergistic phagocytosis of leukemic cells in vitro and near 
100% long-term durable remissions in an aggressive nonclinical leukemia mouse model, 
compared with modest effects with either monotherapy. These data support the mechanistic and 
nonclinical rationale for combining magrolimab with azacitidine in AML. Further nonclinical 
data including efficacy, toxicology, and pharmacology are provided in the current IB.
1.2.3.
Clinical Studies of Magrolimab
1.2.3.1.
Summary of Clinical Pharmacology
Clinical pharmacokinetic (PK) data have been collected in all ongoing studies of magrolimab 
conducted to date. Pharmacokinetic data have been analyzed in a Phase 1 study (SCI-CD47-001) 
in patients with solid tumors. In this study, patients were treated with weekly magrolimab doses 
ranging from 0.1 to 45 mg/kg, with increasing plasma concentrations associated with increasing 
dose. Nonlinear PK consistent with target-mediated clearance was observed over this dose range. 
However, at maintenance doses of 10 mg/kg and above, target-mediated clearance was saturated 
within the dosing regimen, and trough levels associated with magrolimab efficacy in nonclinical 
studies were achieved. Nine of 88 (10%) evaluable patients tested positive for antidrug antibody 
(ADA) against magrolimab at any time point including baseline; ADA positivity had no impact 
on PK or clinical safety in these patients.
In a Phase 1 AML study (SCI-CD47-002), similarly to the solid tumor Phase 1 study, nonlinear 
PK consistent with target-mediated clearance was observed. Three of 20 (15%) evaluable 
patients tested positive for ADA against magrolimab at any time point including baseline; ADA 
positivity had no impact on PK. Antidrug antibody positivity in either study was not associated 
with increased adverse events (AEs).
Preliminary PK data of magrolimab from other ongoing studies (5F9003, 5F9004, 5F9005, and 
5F9006) indicate similar PK properties across all tumor populations and in the presence of 
co-administered drugs. Across all studies, 34 of 507 (6.7%) patients tested positive for ADA 
against magrolimab at any time point including baseline. Antidrug antibody positivity was not 
associated with changes in PK or AE profile.

A preliminary population PK analysis of combined magrolimab PK data indicated that results for 
magrolimab population PK were typical of other nonlinear antibodies. No clinically significant 
covariates of PK variability were identified.
1.2.3.2.
Summary of Clinical Safety
Magrolimab is administered as an intravenous (IV) infusion and it is being studied in several 
clinical studies in MDS, AML, and solid tumors.
Magrolimab has been evaluated as a monotherapy or in combination in multiple solid tumor 
types. In the Phase 1 study SCI-CD47-001 of magrolimab monotherapy, 88 patients with 
advanced solid tumors were treated with magrolimab doses up to 45 mg/kg. No maximum 
tolerated dose (MTD) was reached. Across 548 patients treated with magrolimab, including 
patients with both solid tumors and hematologic malignancies, fatigue, anemia, and headache 
were the 3 most frequently reported AEs (43.0%, 40.8%, and 36.4% of patients, respectively). 
Patients experienced mostly Grade 1 and 2 fatigue (2.8% of patients reported severe fatigue).
Anemia is the most common treatment-related AE, reported in 35.4% of patients. Approximately 
13% of all patients experienced anemia Grade 1 or 2, and 22% experienced severe anemia. 
Notably, many events of severe anemia occurred in patients with AML and MDS who had severe 
anemia at baseline. Anemia was typically manifested as a decline in hemoglobin observed within 
the first 2 weeks of treatment. The initial decrease in hemoglobin after the first dose averages 
0.4 to 1.5 g/dL, with hemoglobin improving in many patients on therapy back to baseline, with a 
decrease in red blood cell (RBC) transfusion requirements for those patients who were 
transfusion-dependent at baseline. In patients with solid tumors, the decrease in hemoglobin was 
followed by a compensatory reticulocytosis, with many patients experiencing a gradual return to 
baseline despite continued dosing. The changes in hemoglobin and reticulocytes described with 
magrolimab treatment are fairly consistent across tumor types and are shown in Figure 1. 
Hyperbilirubinemia (predominately unconjugated) indicates extravascular hemolysis consistent 
with phagocytic removal of RBCs arising from the blockade of CD47 signaling. Administration 
of a low priming dose of magrolimab mitigated on-target anemia, an effect that is mostly 
observed after the first dose.

The red blood cell profile of a solid tumor patient treated with magrolimab monotherapy is shown {Sikic 2019}.
Infusion-related reactions (IRRs) are also a commonly reported AE with magrolimab. Of 
548 patients across 5 studies, 29% had at least 1 IRR. Most common signs and symptoms of IRR 
related to magrolimab included chills, pyrexia, back pain, headache, nausea, vomiting, dyspnea, 
anemia, and blood bilirubin increase. These IRRs were generally observed during the initial 
2 doses of magrolimab. Current recommendations for premedication and IRR management are 
described in Sections 5.5.3 and 5.5.4.
Lastly, hemagglutination (RBC agglutination) as observed on the peripheral smear is a common 
treatment effect and was reported as a treatment-related AE in 11.8% of all patients. Transient 
hemagglutination is observed after the initial priming or first maintenance dose of drug; 
however, it is less common thereafter, and has not been consistently correlated with any clinical 
sequelae.
As of December 2020, 52 untreated induction chemotherapy-ineligible AML patients have been 
enrolled in Study 5F9005 and received the combination of magrolimab + azacytidine {Sallman 
2020b}. The safety profile of magrolimab in combination with azacitidine was acceptable and 
consistent with azacitidine monotherapy, with no significant increases in cytopenias or immune-
related AEs. No MTD was reached with magrolimab dosing of 30 mg/kg weekly. The most 
common treatment-related AEs with magrolimab were anemia (31%), fatigue (19%), blood 
bilirubin increased (19%), neutropenia (19%), thrombocytopenia (17%), and nausea (15%). 
Treatment discontinuation due to any drug-related AEs occurred in 2 of 52 patients (3.8%).

Summary of Clinical Safety and Efficacy of Magrolimab + Venetoclax + 
Azacitidine in AML
In Study 5F9005, clinical activity was assessed for magrolimab + azacitidine in patients with 
treatment-naive/unfit AML and treatment-naive intermediate to higher risk (by Revised 
International Prognostic Scoring System [IPSS-R]) MDS {Sallman 2020b}. As of 
December 2020, a total of 52 AML patients (including 65% with TP53 mutation) were treated 
with magrolimab + azacitidine and 34 of them were evaluable for efficacy. The objective 
response rate (ORR) was 65% (22 patients), with 44% achieving a CR, 12% achieving CRi, 3% 
achieving partial response, and 6% achieving morphologic leukemia-free state (MLFS). Time to 
response was rapid, with a median of 2.04 months. Of the responding patients who had abnormal 
cytogenetics at baseline, 47% achieved complete cytogenetic response. Additionally, 37% of 
responding AML patients achieved minimal residual disease (MRD) negativity, as assessed by 
multiparametric flow cytometry. In AML patients harboring TP53 mutations, the ORR was 
71% (15 of 21 patients) with a CR rate of 48% (10 of 21 patients), 19% (4 of 21 patients) of 
patients achieving CRi, and 5% (1 of 21 patients) achieving MLFS {Sallman 2020b}. The

efficacy of magrolimab + azacitidine appears improved compared to azacitidine monotherapy 
based on data from historical trials, in which CR rates are between 10% and 20%. High rates of 
MRD negativity and prolonged OS are encouraging.
An investigator-initiated study (IIS) sponsored by the MD Anderson Cancer Center (protocol ID 
2020-0027) commenced in the second half of 2020 to evaluate the safety, tolerability, 
recommended Phase 2 dose, and preliminary efficacy of magrolimab in combination with 
azacitidine and venetoclax in patients with relapsed/refractory (R/R) AML and patients with 
newly diagnosed AML who are ineligible for intensive chemotherapy or with poor-risk 
karyotype or molecular markers. In the 6 patients with R/R AML enrolled in the safety run-in 
cohort, no dose-limiting toxicity (DLT) was reported. None of the 19 patients with AML 
(9 frontline and 10 R/R) enrolled before 01 March 2021 died within 60 days of receiving their 
first dose of study drugs. Of the 9 newly diagnosed patients with AML considered ineligible for 
intensive therapy due to age/comorbidities/poor-risk karyotype or molecular markers, the ORR 
was 88.9 % (CR of 66.7% and CRi of 22.2%). Out of these 9 first-line AML patients, 5 harbored 
TP53 mutations and ORR in this population was 80 % (CR and CRi of 40% respectively).
Adverse events reported in more than 2 patients in the IIS are presented in Table 3 (data on file). 
Adverse events reported in more than 2 patients in the IIS with the TP53 mutation are presented 
in Table 4 (data on file) and are similar to those reported in all AML patients.
Overall, these preliminary data suggest that the combination of magrolimab with azacitidine and 
venetoclax has an acceptable safety profile and encouraging clinical efficacy in limited follow up 
in frontline AML ineligible for intensive chemotherapy (Unpublished data, 
 
Anderson Cancer Center, MDACC).

Information About Venetoclax, Azacitidine
1.3.1.
Description of Venetoclax
Venetoclax is a selective, orally bioavailable, small-molecule Bcl-2 family inhibitor that binds 
with high affinity (inhibitory constant < 0.010 nM) {Souers 2013}.
Anti-apoptotic Bcl-2 family members are associated with tumor initiation, disease progression, 
and chemotherapy resistance {Fesik 2005}. Overexpression of Bcl-2 has been demonstrated in 
AML and chronic lymphocytic leukemia (CLL) cells, where it mediates cell survival and 
resistance to chemotherapeutic agents. Venetoclax restores apoptosis by binding to Bcl-2 protein, 
thereby displacing pro-apoptotic proteins such as bcl-2–interacting mediator of cell death, 
triggering mitochondrial outer membrane permeabilization and the activation of caspases. 
Venetoclax has demonstrated cell-killing activity against patient-derived CLL cells and AML 
cells and a variety of lymphoma and leukemia cell lines.
In the US, venetoclax in combination with azacitidine, decitabine, or low-dose cytarabine is 
approved for the treatment of newly diagnosed AML in adults who are ≥ 75 years of age, or who 
have comorbidities that preclude use of intensive induction chemotherapy {VENCLEXTA 
2020}.
In the European Union (EU), venetoclax monotherapy is approved for the treatment of adult 
patients with CLL and for use in combination with hypomethylating agents for the treatment of 
adult patients with newly diagnosed AML who are ineligible for intensive chemotherapy. For 
additional information on venetoclax, please refer to the prescribing information.
1.3.2.
Description of Azacitidine
Azacitidine is a nucleoside analog, specifically a chemical analog of cytidine. Azacitidine has 
2 known primary antineoplastic MOAs: 1) inhibition of DNA methyltransferase leading to 
hypomethylation of DNA and 2) direct cytotoxicity of malignant hematopoietic cells through cell 
death via its incorporation into DNA and RNA.
Azacitidine is a SOC and approved in the US for treatment of subtypes of MDS including, but 
not limited to, MDS with refractory anemia with excess blasts, a subtype that is mostly 
composed of patients with intermediate- to very high-risk MDS by IPSS-R criteria {VIDAZA 
2018}. Azacitidine is also an SOC therapy for previously untreated patients with AML who are 
ineligible for induction chemotherapy or SCT based on age, comorbidities, or other factors. In 
Europe, azacitidine is approved for patients with intermediate-2 and high-risk MDS according to 
International Prognostic Scoring System criteria and for patients with AML who are ineligible 
for SCT. For additional information on azacitidine, refer to the prescribing information.

Clinical Data for Venetoclax + Azacitidine
Venetoclax in combination with azacitidine or decitabine was studied in M14-358, a 
non-randomized, open-label clinical study involving patients with newly diagnosed AML 
{VENCLEXTA 2020}. Sixty-seven of the 84 patients who received venetoclax with azacitidine 
were ≥ 75 years of age or had comorbidities that precluded the use of intensive induction 
chemotherapy. Patients received venetoclax after a 5-week ramp-up to a final 400-mg once-daily 
oral dose and azacitidine at the standard dosing. The median follow-up was 15.9 months (range: 
0.4 to 40.3 months). Forty-three percent (29 of 67 patients) achieved a CR (95% CI: 31%, 56%) 
and 18% (12 of 67 patients) achieved a CR with partial hematologic recovery (CRh) (95% CI: 
9.6%, 29%). Median time to first CR or CRh was 1.0 month (range: 0.7 to 8.9 months). The 
median duration of CR was 23.8 months (95% CI: 15.4, –) and the median duration of CR or 
CRh was 26.5 months (95% CI: 17.4, –). Of patients treated with venetoclax in combination with 
azacitidine, 12% (8 of 67) subsequently received SCT. Seventeen of the 84 patients who received 
venetoclax with azacitidine were 65 to 74 years of age and did not have known comorbidities 
that precluded the use of intensive induction chemotherapy. For the 17 patients treated with 
venetoclax in combination with azacitidine, the CR rate was 35% (95% CI: 14%, 62%) and the 
CRh rate was 41% (95% CI: 18%, 67%). Nine patients (53%) subsequently received SCT. The 
most common AEs of any grade observed with patients treated with venetoclax and azacitidine 
or venetoclax and decitabine were febrile neutropenia (69%), fatigue (62%), constipation (62%), 
musculoskeletal pain (54%), dizziness (54%), nausea (54%), abdominal pain (46%), diarrhea 
(46%), pneumonia (46%), sepsis (excluding fungal; 46%), cough (38%), pyrexia (31%), 
hypotension (31%), oropharyngeal pain (31%), edema (31%), and vomiting (31%).
The Phase 3 randomized, double-blind, placebo-controlled study VIALE-A, investigating 
venetoclax in combination with azacitidine versus azacitidine in combination with placebo in 
treatment-naive AML patients who are ineligible for intensive chemotherapy, confirms the 
efficacy of venetoclax + azacitidine with a statistically significant improvement in OS. Median 
OS with venetoclax + azacitidine was 14.7 months, while the median OS with 
azacitidine + placebo was 9.6 months (HR 0.66 [95% CI: 0.52, 0.85]; p < .001) {DiNardo 2020}. 
Safety of the combination in VIALE-A was similar to what had been previously reported and can 
be managed with standard supportive care.
1.3.4.
 Information About Auxiliary Medicinal Products/Noninvestigational 
Products
Acetaminophen (also known as paracetamol), diphenhydramine, and corticosteroids 
(dexamethasone) are considered auxiliary medicinal products (AxMPs) for this clinical study 
(Appendix 14). Acetaminophen is approved for pain relief and fever reduction. 
Diphenhydramine is an antihistamine and is used for amelioration of allergic reactions. 
Corticosteroids are anti-inflammatory medications and are used for the amelioration of allergic 
reactions. The use of these medications on this study is described in Section 5.5.4. 
Additional details on acetaminophen, diphenhydramine, and corticosteroids can be found in the

Rationale for This Study
Magrolimab is under clinical evaluation in combination with azacitidine in the ongoing Phase 1b 
study, 5F9005, in patients with AML who are previously untreated and ineligible for intensive 
induction chemotherapy. Among 34 evaluable patients, 65% achieved an OR and 44% achieved 
a CR. Time to response was rapid (median 2.04 months) {Sallman 2020a}. Clinical activity has 
also been observed in patients with the TP53 mutation, a poor-risk subgroup with an overall 
response rate of 71%. Median OS was 12.9 months in patients with the TP53 mutation and 
18.9 months in patients with wild-type TP53. Given the encouraging efficacy data observed with 
the magrolimab plus azacitidine and venetoclax plus azacitidine double combinations, the triple 
combination of magrolimab plus azacitidine plus venetoclax is anticipated to show superior 
activity over either double combination. In terms of safety, the addition of magrolimab to 
venetoclax and azacitidine is not anticipated to have overlapping toxicities, as magrolimab 
monotherapy does not cause myelosuppression, which is a key toxicity of venetoclax and 
azacitidine. These hypotheses are supported by preliminary data from the MD Anderson Cancer 
Center IIS that have shown no DLT, no deaths within 60 days of the first dose of study drugs, 
and signs of encouraging early efficacy in patients treated with the combination of magrolimab 
with azacitidine and venetoclax in frontline AML. Emerging data from this study have informed 
design elements for the current study.
Furthermore, nonclinical data demonstrate that venetoclax can enhance magrolimab-mediated 
phagocytosis, which can be further enhanced by azacitidine (Figure 2).

Human macrophages were incubated with AML HL60 cells in the presence of the indicated therapeutic agents with macrophage 
phagocytosis of AML cells measured. 
Additional nonclinical study in vitro suggests that in a variety of AML-derived cell lines, 
including sub-lines with intrinsic resistance to venetoclax + azacitidine-induced cytotoxicity, 
these agents can nonetheless increase phagocytosis by macrophages, likely due to upregulation 
of prophagocytic signals on the cell surface. Fmi he1more, co-treatment with magrolimab can 
fmiher increase phagocytosis in combination with venetoclax and azacitidine (Figure 3).

Magrolimab, venetoclax, and azacitidine have been tested in combination in an in vivo model of 
primary human AML engrafted into immunocompromised mice. Following engraftment and 
detectable disease burden in the peripheral blood, mice were treated with vehicle control, a 
combination of venetoclax and azacitidine, magrolimab (5F9), or a combination of magrolimab, 
venetoclax, and azacitidine. In this model, venetoclax plus azacitidine has no efficacy; in 
contrast, magrolimab monotherapy significantly extends survival. The combination of 
magrolimab plus venetoclax plus azacitidine shows synergistic efficacy, extending mouse 
survival to a greater degree than the other therapeutic regimens tested (Figure 4).

In summary, the nonclinical rationale and clinical data support the evaluation of magrolimab in 
combination with azacitidine and venetoclax in frontline AML patients who are ineligible for 
intensive chemotherapy.
1.5.
Rationale for Dose Selection of Magrolimab
The rationale for the magrolimab dose proposed in this study originates from safety, efficacy, 
and PK/pharmacodynamics (PD) data, and modelling and simulation analyses based on data 
obtained from all ongoing and completed clinical studies with magrolimab in patients with solid 
tumors, NHL, and AML/MDS.
In the first-in-human study of magrolimab (SCI-CD47-001) in patients with solid tumors and 
lymphomas, after an initial priming dose of 1 mg/kg on the first day, magrolimab was tested as a 
monotherapy at weekly doses of up to 45 mg/kg. The use of an initial 1 mg/kg priming dose was 
integrated into the dosing regimen to mitigate the on-target anemia induced by CD47 blockade. 
An initial priming dose leads to elimination of aged RBCs that are sensitive to CD47 blockade 
and triggers reticulocytosis of young RBCs that are not affected by CD47 blockade {Chen 
2018}. Utilizing a priming dose leads to an initial, transient, and mild anemia that generally 
normalizes back to baseline over several weeks, even in the presence of repeated therapeutic 
doses of magrolimab {Advani 2018, Liu 2015a, Sikic 2019}. The maximum weekly dose of 
45 mg/kg has an acceptable safety profile, and no MTD was identified in this study.

Amendment 7 
In studies SCI-CD47-002 and 5F9005 in patients with AML/MDS, magrolimab was 
administered as a monotherapy at doses of up to 30 mg/kg twice weekly and in combination with 
azacitidine at doses of up to 30 mg/kg once weekly. In these studies, no significant DLT was 
observed, and magrolimab had an acceptable safety profile over the tested dose range up to a 
maximum of 30 mg/kg twice weekly. Fmthe1more, in these 2 studies, an intrapatient dose 
escalation approach was followed; after the priming dose, the patients received a dose of 
15 mg/kg on Day 8 during Week 2, after which the dose was escalated to 30 mg/kg on Day 11 
and weekly thereafter through the end of Cycle 1, and eve1y 2 weeks from Cycle 2 and onward. 
This schedule was based on nonclinical data indicating enhanced safety of intrapatient dose 
escalation. The MD Anderson Cancer Center IIS evaluating the combination of magrolimab with 
venetoclax and azacitidine used the same dosing schedule for magrolimab, with venetoclax and 
azacitidine dosed per their USPI, and no DLT was observed during the safety nm-in. 
In studies 5F9003 and 5F9004, magrolimab, in combination with rituximab and cetuximab, 
respectively, was found to have an acceptable safety profile at doses up to 45 mg/kg eve1y week 
followed by eve1y other week. 
The proposed dosing regimen of magrolimab in this study is expected to have an acceptable 
safety profile based on the entirety of safety data in multiple oncology populations including the 
proposed study population, both as a monotherapy and in combination with other tumor-targeted 
antibodies and chemotherapeutics. 
In Study SCI-CD47-002 and Study 5F9005, CD47 RO by magrolimab was tested at baseline and 
at multiple time points on treatment, on both peripheral blood and bone manow cells, including 
leukeinic blasts. A PK/PD model linking dose exposure and blood and bone maiTow RO was 
developed and described these data well. Simulations with the model predicted that > 90% RO 
would be achieved in the bone maiTow cells at the magrolimab dosing regimens proposed in this 
study. This level of RO is typically associated with maximal efficacy for all immune-oncology

Based on results from the Phase 1 b study of magrolimab in MDS and AML (Study 5F9005) and 
the MD Anderson Cancer Center IIS, the cmTent study is designed to employ the same 
intrapatient dose escalation regimen for magrolimab to mitigate on-target toxicities such as 
anemia and other toxicities observed in nonclinical AML models. Treatment should be continued 
until disease progression, relapse, loss of clinical benefit, or unacceptable toxicity occur, or other 
study discontinuation criteria are met. Clinical benefit, as dete1mined by the investigator, can 
include transfusion independence, adequate blood counts, symptomatic improvement, or other 
criteria as dete1mined by the investigator. 
In smnmaiy, the proposed dose regimens have been shown to have acceptable safety profiles in 
oncology patient populations. Based on PK/PD modeling, the proposed doses are predicted to 
result in optimal efficacy in myeloid malignancy populations and maximize patient and caregiver 
convemence.

Risk/Benefit Assessment for the Study
Nonclinical data demonstrate enhanced efficacy when magrolimab is combined with venetoclax 
and azacitidine. Furthermore, encouraging clinical activity has been observed with both 
magrolimab plus azacitidine and venetoclax plus azacitidine double combinations, and supports 
the concept that a triple combination may lead to improved efficacy. Preliminary data from the 
MD Anderson Cancer Center IIS suggest encouraging clinical efficacy in frontline AML in 
patients ineligible for intensive chemotherapy.
Venetoclax and azacitidine have overlapping toxicities, particularly myelosuppression and 
infections. Anemia, neutropenia, thrombocytopenia, and infections have been reported in patients 
treated with magrolimab. 
Specific safety assessments to monitor for expected toxicities to each of these agents will be 
implemented. These include monitoring for myelosuppression, tumor lysis syndrome (TLS), 
hepatotoxicity, IRRs, and other expected toxicities. Detailed guidance on dose modification/dose 
holds for each study drug, depending on the type of toxicity, is provided in Section 5.5.
An infectious disease pandemic may pose additional risks to study drug availability, study visit 
schedule, and adherence to protocol-specified safety monitoring or laboratory assessments. Refer 
to Appendix 2 for further details on the risks and risk mitigation strategy. Given the risk 
mitigation measures that are being implemented, the expected benefit-risk assessment to patients 
remains unchanged.
In summary, based on strong scientific rationale, nonclinical and emerging clinical efficacy data, 
and the manageable safety profile with the proposed magrolimab combination regimens, this 
study has an acceptable risk/benefit ratio for patients who participate.

magrolimab + venetoclax + azacitidine versus placebo + venetoclax + azacitidine in newly 
diagnosed, previously untreated patients with AML who are ineligible for intensive 
chemotherapy.
Approximately 432 patients will be randomized in 1:1 ratio to receive either magrolimab + 
venetoclax + azacitidine (experimental arm) or placebo + venetoclax + azacitidine (control arm). 
Randomization will be stratified by 3 factors:
•
age (< 75 years, ≥ 75 years)
•
genetic risk group (favorable/intermediate, adverse, unknown) (Appendix 8)
•
geographic region (United States [US], outside the US)
The study schematic is presented in Figure 5.

•
Disease progression (including treatment failure and relapse)
•
Unacceptable toxicity
•

If azacitidine is permanently discontinued, the patient must discontinue the remaining study 
treatment.
Although disease progression is considered a sufficient reason for discontinuing a patient from 
study treatment, given the delayed treatment benefit commonly seen in immune therapies, the 
investigator is advised to continue to treat the patient until the investigator considers the study 
treatment to be no longer clinically beneficial to the patient, or the change of disease state 
renders the patient unacceptable for further treatment in the judgment of the investigator. 
All patients must be followed through completion of all study treatment.
If patients remain on study drugs beyond disease progression, a second bone marrow assessment, 
along with required laboratory tests for response assessment, should be done within 4 weeks. If 
disease progression is confirmed at the second bone marrow assessment, the patient should be 
discontinued from the study treatment and participate in long-term follow-up and survival 
assessment if the patient does not start a new anti-AML therapy.
Patients who discontinue study treatment are to return for an end-of-treatment (EOT) visit for 
evaluation of safety within 7 days (± 7 days) of their last dose or the decision to end study 
treatment, whichever is later. In addition, patients are to have a safety follow-up telephone call 
30 days and 70 days (± 7 days) after their last dose of study treatment. When a serious adverse 
event (SAE) or treatment-related AE is reported during the telephone call, the patient should 
come to the clinic for physical examination and blood tests, if clinically needed. Follow-up for 
ongoing SAEs or treatment-related AEs after the safety follow-up visit/call will stop if a patient 
begins another anti-AML therapy – this is only applicable after the 30 day visit/call.
All patients who discontinue study treatment for reasons other than death or start of new 
anti-AML therapy (except maintenance and SCT) will participate in long-term follow-up for 
disease response unless the patient withdraws consent for such follow-up and withdraws 
completely from the study. For patients who come off the study treatment to receive an SCT, 
follow-up for response assessment and collection of bone marrow aspirate results will continue 
until start of new anti-AML therapy (except post SCT maintenance) (Appendix Figure 1). When 
considering SCT, note that no significant magrolimab-related transplant complications have been 
observed in patients who have achieved a response and undergone SCT in an ongoing 
magrolimab study in AML and MDS (Study 5F9005); however, a 4-week wash-out period for 
magrolimab/placebo is recommended prior to SCT.
All patients will be followed for survival until death, withdrawal of consent, loss to follow-up, 
completion of survival follow-up, or study termination by the sponsor, whichever occurs first. 
Duration of survival follow-up will be limited to 5 years from the EOT visit for each patient. If a 
patient discontinues study treatment and does not consent to continued follow-up, the 
investigator must not access confidential records that require the patient’s consent. However, an 
investigator may consult public records to establish survival status. For any patient who dies 
during this follow-up period, the immediate cause of death must be reported to the sponsor.

If a patient discontinues study dosing (for example, as a result of an AE), every attempt should 
be made to keep the patient in the study and continue to perform the required study-related 
follow-up and procedures. If this is not possible or acceptable to the patient or investigator, the 
patient may be withdrawn from the study. For patients who discontinue from the study prior to 
completion of all protocol-required visits for study assessments or survival follow-up as 
described in the schedule of assessments (Appendix Table 5), the investigator may search 
publicly available records (where permitted by local laws and regulations) to ascertain survival 
status unless the patient withdraws consent for such follow-up. This ensures reduced risk of 
missing critical efficacy data.
The assessments to be performed at each of the posttreatment visits are listed in Appendix 
Table 5.
3.5.
End of Study
All Patients: The end of the entire study for all patients is defined as the date on which the last 
patient remaining on study completes the last study visit/call or when the sponsor decides to end 
the study. The sponsor reserves the right to terminate the study at any time for any reason 
(including safety).
Individual Patients: Patients are considered to have reached the end of study when they are no 
longer followed for long-term or survival follow-up (up to 5 years from the EOT visit) due to the 
following reasons: death, loss to follow-up, withdrawal of consent, or sponsor termination of 
study.
3.6.
Poststudy Care 
Upon withdrawal from study treatment, patients will receive the care upon which they and their 
physicians agree. Patients will be followed for survival, efficacy, and AEs as specified in 
Appendix Table 5. 
3.7.
Source Data
The source data for this study will be obtained from original records (eg, clinic notes, hospital 
records, patient charts), local and/or specialty laboratory testing (for PK, ADA and/or PD data), 
patient-reported outcome (PRO) data, and/or additional biomarker testing.

Randomization, Blinding, and Treatment Codes Access
5.1.1.
Randomization
Patients who meet randomization eligibility criteria will be randomized in a 1:1 ratio using an 
interactive response technology (IRT) to either the experimental arm or the control arm. The first 
dose of study treatment should be administered within 72 hours of randomization.
To achieve balance between treatment arms, randomization will be stratified according to the 
following factors:
•
age (< 75 years, ≥ 75 years)
•
genetic risk group (favorable/intermediate, adverse, unknown)
•
geographic region (US, outside the US)
The randomization list will be generated with a 3-factor stratified block randomization by 
Signant Health (https://www.signanthealth.com/) using SAS statistical software.
5.1.2.
Blinding
During the randomized phase, the investigators, the study site personnel, the patients, the study 
management team, and all personnel directly involved with the conduct of the study will remain 
blinded to treatment assignment until the primary analysis of OS.
Specified personnel may be unblinded based on their study role. The Pharmacokinetics File 
Administrator, or designee, in Bioanalytical Operations and/or Clinical Data Management who 
facilitates the data transfer of PK files between Gilead and vendors will remain unblinded. 
Individuals in Clinical Packaging and Labeling or Clinical Supply Management who have an 
Unblinded Inventory Manager role in the IRT for purposes of study drug inventory management 
will remain unblinded. Individuals in Patient Safety (PS) who are responsible for safety signal 
detection, investigational new drug safety reporting, and/or expedited reporting of suspected 
unexpected serious adverse reactions may be unblinded to individual case data and/or 
group-level summaries. External (ie, contract research organization [CRO], independent data 
monitoring committee [DMC]) biostatisticians and programmers responsible for preparing 
interim tables, listings, and figures for the DMC will be unblinded. The laboratories that will 
store and/or analyze blood samples for conducting PK and ADA analysis will be unblinded. 
Regulatory Quality and Compliance personnel in Research and Development may also be 
unblinded for purposes of supporting quality assurance activities and/or regulatory agency 
inspections.
The sponsor study team will remain blinded until the primary analysis of OS.

Planned Interim Unblinding
To assess the safety and efficacy of magrolimab + venetoclax + azacitidine and for the interim 
analysis planning and program development consideration, a DMC independent of the blinded 
study team will be assembled. The DMC will be granted access to unblinded clinical data, 
including treatment assignments, to closely monitor study progress and drug safety. The 
membership, conduct, and meeting schedule of the DMC will be documented in the DMC 
charter.
A Gilead internal unblinded team independent of the blinded study team may be assembled, to 
assess the safety and/or efficacy of magrolimab + venetoclax + azacitidine for planning and 
development purposes. This group will consist of at least 1 representative from Clinical 
Research, Biostatistics, and Global Patient Safety, and may include other personnel as necessary. 
The Gilead medical monitor and clinical research personnel directly interacting with the study 
center will not be unblinded to the patient treatment assignment. The Gilead internal unblinded 
team will be granted access to unblinded clinical data at the group summary level including 
treatment assignments to closely monitor study progress and drug safety. 
The membership, conduct, and meeting schedule of the internal unblinded team will be 
documented in the Gilead Data Review Committee Charter as specified in Gilead procedural 
documents.
At the time of the second interim analysis, the DMC will review the unblinded analysis results. If 
the null hypothesis on OS is rejected, and Gilead determines to start the marketing application 
process, the Gilead study team may remain blinded, and a separate Gilead internal team 
responsible for the marketing application may be assembled, and unblinded for all enrolled 
patients and remain blinded for future patients. This group will consist of at least 1 representative 
from Clinical Research, Biostatistics, and Global Patient Safety, and may include other personnel 
as necessary.
5.1.4.
Procedures for Breaking the Blind on Treatment Codes
In the event of a medical emergency requiring breaking the blind to provide medical care to the 
patient, the investigator may obtain the patient’s treatment assignment directly from the IRT for 
that patient (IRT vendor may be contacted in case of technology failure). Gilead recommends but 
does not require that the investigator contact the Gilead medical monitor before breaking the 
blind. Treatment assignment should remain blinded unless that knowledge is necessary to 
determine patient emergency medical care. The rationale for unblinding must be clearly 
explained in source documentation along with the date on which the treatment assignment was 
obtained. The investigator is requested to contact the Gilead medical monitor promptly in case of 
any treatment unblinding.
Blinding of study treatment is critical to the integrity of this clinical study. Therefore, if a 
patient’s treatment assignment is disclosed to the investigator, the patient will have study 
treatment discontinued. All patients will be followed until study completion unless consent to do 
so is specifically withdrawn by the patient. During long-term or survival follow-ups, patients can 
receive new anti-AML therapy as per investigator’s judgment.

Dosage and Administration of Study Drugs
5.5.1.
Dose and Administration of Magrolimab/Placebo
The magrolimab/placebo dosing regimen is presented in Table 6. The treatment schedule is 
provided in Appendix Table 2.
Premedication requirements are provided in Section 5.5.4.
Magrolimab/placebo will be administered by IV infusion. The duration of infusion will be 
3 hours (± 30 minutes) for the first 3 doses of magrolimab/placebo, and then 2 hours 
(± 30 minutes) for infusions beyond the first 3 doses. Magrolimab/placebo doses should not be 
given on consecutive days. The reduced infusion time to 2 hours is utilized based on prior data 
demonstrating majority CD47 RO on peripheral blood cells, thus mitigating anticipated RBC 
toxicities from magrolimab.
During the first 4 weeks of treatment, WBC count must be ≤ 20  103/µL prior to each 
magrolimab/placebo dose. Patients with WBC > 20  103/µL can be treated with hydroxyurea 
and/or leukapheresis throughout the study to reduce the WBC to ≤ 20  103/µL.

Within 24 hours prior to each of the first 2 doses of magrolimab/placebo infusion during initial 
treatment, all patients must have a documented hemoglobin ≥ 9 g/dL based on CBC result. 
Patients who do not meet these criteria must be transfused and have their hemoglobin rechecked 
to meet 9 g/dL prior to each of the first 2 doses of magrolimab/placebo (Section 5.5.3.1).
Hemoglobin must be checked again 3 to 6 hours after the initiation of the first and second doses 
of magrolimab/placebo during initial treatment. The patient should be transfused as clinically 
appropriate. Investigators should consider additional hemoglobin monitoring during the first 
week of treatment in patients with symptoms of anemia or at increased risk for complications of 
anemia.
All patients should be monitored hourly during infusion and for 1 hour after infusion for priming, 
repriming/re-escalation, and maintenance doses during the 4 first weeks. Patients should be 
monitored (including measurement of vital signs, as clinically appropriate) for signs and 
symptoms of IRR, which have been observed in previous magrolimab studies. Postinfusion 
monitoring should begin after the infusion is complete. Postinfusion monitoring is not required 
for doses after Day 22. Patients who experience any treatment-emergent AEs during the 
observation period should be further monitored, as clinically appropriate.
The dose of magrolimab/placebo will be calculated based on actual weight at randomization 
(using weight obtained either at screening or on Cycle 1 Day 1) and remains constant throughout 
the study unless there is a > 10% change in body weight from baseline. Modifications to the 
study treatment doses administered should be made for a > 10% change in body weight from 
baseline and according to local and regional prescribing standards. Dose modifications for 
changes in body weight ≤ 10% may be made according to local institutional guidelines.
Patients will continue study treatment until they show evidence of disease progression, relapse, 
loss of clinical benefit, or unacceptable toxicity (further details about treatment discontinuation 
are provided in Sections 3.3 and 3.5).
5.5.1.1.
Treatment Delay and Repriming/Re-escalation for Magrolimab/Placebo
Given the large CD47 antigen sink on normal cells, patients who have a long dose delay of 
magrolimab/placebo are required to be reprimed with magrolimab dosing to resaturate the CD47 
antigen sink. Guidelines for repriming/re-escalation for magrolimab/placebo after a dose delay 
are provided in Section 5.5.1.2.
5.5.1.2.
General Guidance on Dose Modification and Delays for Magrolimab/Placebo
Clinical safety and PK data from dose finding studies in both solid tumor and hematologic 
malignancies have not demonstrated any dose-dependent toxicities associated with magrolimab. 
Dose reduction/modification of magrolimab/placebo may be allowed in certain circumstances 
(eg, with certain AEs), with approval by the sponsor. If treatment-emergent and/or 
magrolimab/placebo-related AEs occur, magrolimab/placebo may be withheld until clinical 
resolution or improvement per the treating physician.

When the combination drugs (azacitidine or venetoclax) are delayed due to toxicities, 
magrolimab/placebo should continue independently as per magrolimab/placebo administration 
schedule (Appendix Table 3). Continuous dosing of magrolimab is needed to maintain 
efficacious exposures; prolonged delays of greater than 1 week when magrolimab is dosed every 
2 weeks have been seen to result in lower clinical efficacy. Magrolimab/placebo may be 
withheld for magrolimab-related AEs: if magrolimab is withheld due to toxicities, any delay 
longer than 3 days should be discussed with the medical monitor.
The repriming guidelines presented in Table 7 should be followed for patients with dose delays. 
In case of repriming, assessments should follow magrolimab repriming table (Appendix 
Table 4).

The start of the cycle is the first day of azacitidine treatment. Venetoclax is to be administered 
along with azacitidine on Day 1 of each cycle.
Azacitidine administration should be completed at least 1 hour before magrolimab/placebo 
administration on days when both drugs are administered. 
Azacitidine will be administered according to region-specific drug labeling, either 
subcutaneously (SC) or IV, at the standard dose of 75 mg/m2 on Days 1 to 7 of each 28-day 
cycle. Azacitidine may be administered on an alternative schedule (such as Days 1 to 5, Day 8, 
and Day 9 of a 28-day cycle) for flexibility and convenience as long as 7 doses of azacitidine are 
administered within 9 consecutive days in accordance with local clinical practice guidelines. 
When administered IV, the total dose of azacitidine (diluted in a 50 to 100 mL infusion bag of 
either 0.9% sodium chloride injection or lactated Ringer’s injection solution) is infused over a 
period of 10 to 40 minutes (refer to the azacitidine local prescribing information for detailed 
instructions for preparation and administration).
The dose of azacitidine will be calculated based on actual weight and height obtained either at 
screening or on Cycle 1 Day 1 and remains constant throughout the study unless there is a 
> 10% change in body weight from baseline. Modifications to the study treatment doses 
administered should be made for a > 10% change in body weight from baseline and according to 
local and regional prescribing standards. Dose modifications for changes in body weight ≤ 10% 
may be made according to local institutional guidelines.
Once the patient has completed the first cycle of treatment, azacitidine may be administered at 
home only on days where magrolimab/placebo is not given and azacitidine is administered alone.
Prior to initiation of venetoclax, WBC count must be ≤ 20  103/µL. Patients with 
WBC > 20  103/µL can be treated with hydroxyurea and/or leukapheresis throughout the study 
to reduce the WBC to ≤ 20  103/µL.
Venetoclax should be administered orally once daily with a meal and water, at approximately the 
same time each day. Patients should be advised to swallow the tablet whole, and not chew, crush, 
or break the tablets. If a dose is missed and it has been less than 8 hours, patients should be 
advised to take their dose as soon as possible. If a dose is missed and more than 8 hours has 
passed, the missed dose should be skipped, and the next dose should be taken at the usual time. If 
a patient vomits after taking venetoclax, an extra dose should not be taken but rather the next 
dose should be taken at the usual time.
For patients taking concomitant CYP3A and P-glycoprotein (P-gp) inhibitors, refer to Table 13 
for venetoclax dosing and administration.

5.5.2.1.
Venetoclax Administration and Tumor Lysis Syndrome
Patients treated with venetoclax may develop tumor lysis syndrome (TLS). Assess blood 
chemistry (potassium, uric acid, phosphorous, calcium, and creatinine) and correct preexisting 
abnormalities prior to initiation of treatment with venetoclax. Blood chemistry must be 
monitored for TLS at predose, 6 to 8 hours after each new dose during ramp-up (Days 1, 2, and 
3), and 24 hours after reaching the maintenance dose.
5.5.3.
Management of Specific Adverse Events and Dose Modification/Delays of 
Study Drugs 
Dose modification and treatment delay of azacitidine may not occur for patients in the initial 
28-day period (Cycle 1).
If  2 doses of azacitidine are missed during the 7-day dosing period, dosing should continue so 
that the patient receives the full 7 days of treatment, as long as these additional doses are given 
within 1 week of the previous dose. If ≥ 3 doses of azacitidine are missed during the 7-day 
dosing period, the investigator should contact the sponsor, and a dosing decision should be made 
on an individual case basis.
General guidance about magrolimab/placebo dose modifications is available in Section 5.5.1.2.
5.5.3.1.
Management of Hematologic Toxicity
Magrolimab may interfere with RBC phenotyping due to expected coating of the RBC 
membrane. Due to the risk of developing anemia, and because magrolimab may make 
phenotyping difficult, any of the 4 blood groups A, B, AB, and O composing the ABO system 
(ABO)/Rhesus factor (Rh) type, antibody screen, blood phenotyping or genotyping, and direct 
antiglobulin test (DAT) need to be performed at screening before exposure to magrolimab, as 
described in Section 5.5.3.1.1.
Red blood cell phenotyping/genotyping, ABO type, and DAT need not be repeated if results 
dated before screening are available. Antibody screen need not be repeated if results dated before 
screening are available, unless the patient was transfused since that time.
5.5.3.1.1.
Anemia, Blood Cross-Matching, and Packed Red Blood Cell Transfusion 
Procedures
Magrolimab binds to RBCs and leads to erythrophagocytosis. CD47 is a member of the Rh 
complex in the RBC’s membrane. Therefore, when magrolimab binds to CD47, it is likely to 
interfere with routine blood bank tests needed in case of transfusion. Notify blood transfusion 
centers/blood banks of this interference with blood bank testing and inform them that a patient 
will receive magrolimab.
In clinical studies, anemia is the most common treatment-related AE and is typically manifested 
as a decline in hemoglobin of about 0.5 to 1.5 g/dL observed in the first 1 to 2 weeks of 
treatment. This decrease in hemoglobin level is acceptable in patients with no other significant 
diseases or medical conditions. However, for patients with significant diseases or medical 

Magrolimab

conditions, such as unstable angina, ischemic heart disease, or uncontrolled diabetes mellitus, 
treatment‑related anemia could be life‑threatening or fatal. Significant drops (2 g/dL or higher) 
have been observed in early doses.
Within 24 hours prior to each of the first 2 doses of magrolimab infusion during initial treatment, 
all patients must have a documented hemoglobin ≥ 9 g/dL based on CBC result. Patients who do 
not meet these criteria must be transfused and have their hemoglobin rechecked to meet 9 g/dL 
prior to each of the first 2 doses of magrolimab.
Patients with a low baseline hemoglobin level, especially those with cardiac history or risk 
factors, must be monitored closely after initial administrations of magrolimab as preexisting 
anemia could be exacerbated. Red blood cell transfusions are permitted prior to study treatment 
to ensure adequate hemoglobin level as per the investigator’s clinical judgment.
Prior to initiation of magrolimab, ABO/Rh type, antibody screen, DAT, and extended RBC 
phenotyping (including minor antigens such as CcDEe, Cw, MNSs, Kk, FyaFyb, and JkaJkb) 
will be performed for each patient. RBC genotyping instead of extended RBC phenotyping is 
acceptable for any patient. RBC genotyping (instead of an extended RBC phenotyping) must be 
performed if a patient received any RBC or whole blood transfusion within the previous 
3 months (unless laboratory has availability for special techniques for performing phenotyping 
for patients with recent transfusion). Results must be available before the first dose of 
magrolimab.
5.5.3.1.1.1.
Management in Patients with Cardiac Comorbidities
Patients with cardiac history (e.g. LVEF ≤ 50%), especially those with low baseline hemoglobin 
levels, must be monitored closely after initial administrations of magrolimab/placebo as pre-
existing anemia could be exacerbated. Enhanced monitoring of hemoglobin with extra CBC and 
careful fluid management, including diuretic administration, during or post transfusion may be 
required for these patients, as clinically needed.
5.5.3.1.1.2.
For Patients After Exposure to Magrolimab/Placebo
Hemoglobin must be checked 3 to 6 hours after the initiation of the first and second doses of 
magrolimab during initial treatment. The patient should be transfused as clinically appropriate. 
Investigators should consider additional hemoglobin monitoring during the first week of 
treatment in patients with symptoms of anemia or at increased risk for complications of anemia.
5.5.3.1.1.3.
Blood Components for Transfusion 
For all elective RBC and platelet transfusions, use leukocyte-reduced and gamma-irradiated units 
per institutional guidelines.
For RBC transfusions, phenotype/genotype matched units are preferred. However, 
cytomegalovirus (CMV)-seronegative units for CMV-seronegative patients will not be required 
for this study.

In case ABO/Rh type cannot be resolved, use pretreatment (historical) phenotype/genotype 
matched units for minor RBC antigens (CcDEe and Kk, to the feasible extent). Regarding the 
ABO type, historical blood group or O type can be used as per the institutional guidelines.
For emergency transfusions, the transfusion centers may consider using emergency Group O red 
cells if phenotype/genotype matched units are not available.
Whenever possible, blood plasma therapy should be blood type specific. Platelets should be 
blood type compatible whenever possible and, if not, should have been tested and found not to 
have high titer anti-A or anti-B. Otherwise, plasma and platelet products can be provided as per 
the institutional policy.
A recent report has suggested that cross-match interference by RBCs due to treatment with 
magrolimab may be resolved by use of gamma-clone anti-IgG and multiple alloadsorptions with 
papain-treated RBC samples, pooled single donor apheresis platelets or commercial human 
platelet concentrate product if required {Troughton 2018, Velliquette 2019}.
5.5.3.1.2.
Neutropenia and Thrombocytopenia:
Neutrophil counts may worsen after administration of magrolimab, leading to severe 
neutropenia. Grade 3 (ANC 500 to < 1000 cells/uL) and Grade 4 (ANC < 500 cells/uL) 
neutropenia have been reported. Additionally, fatal events of febrile neutropenia have been 
reported in patients treated with magrolimab. Close hematological monitoring is required for all 
patients during treatment. In cases of neutropenia, consider antimicrobial prophylaxis and 
administration of granulocyte-colony stimulating factor (G-CSF) if clinically appropriate. If 
febrile neutropenia occurs, administer antibiotics and/or antimycotics.
Dose modification guidelines for magrolimab in the case of severe neutropenia or 
thrombocytopenia are provided below:
•
Before achieving remission (ie, bone marrow blast count < 5%), for Grade 4 neutropenia 
(ANC < 500/uL) with or without fever or infection, delay of magrolimab/placebo dosing is 
not recommended. In cases of Grade 4 neutropenia with serious infection, recommendations 
for dose delay are provided in Section 5.5.3.2.2. 
•
After achieving remission, for Grade 4 neutropenia (ANC < 500/uL) with or without fever or 
infection, and lasting at least 14 days, magrolimab/placebo dose delay is required. Upon 
resolution to Grade ≤ 2, resume magrolimab/placebo at the same dose. 
•
Before achieving remission, for Grade 4 thrombocytopenia, delay of magrolimab/placebo 
dosing is not recommended.
•
After achieving remission, for Grade 4 thrombocytopenia lasting at least 14 days, 
magrolimab/placebo dose delay is required. Upon resolution to Grade ≤ 2, resume 
magrolimab/placebo at the same dose.
Dose modifications and delays of venetoclax and/or azacitidine due to neutropenia and

Infusion-related Reactions
Infusion-related reactions are defined by the NCI CTCAE Version 5.0 (under the category 
“General disorders and administration site conditions”) as “a disorder characterized by adverse 
reaction to the infusion of pharmacological or biological substances” (Appendix 6). For the 
purposes of this study, the time frame for IRR assessment is the 24-hour period beginning from 
the start of the infusion. Premedication as described in Section 5.5.4 will be used to manage 
IRRs preemptively.
Recommendations for the management of infusion-related reactions related to magrolimab are 
provided in Table 10.

Remain at bedside and monitor patient until recovery from symptoms.
Patients who experience an IRR with the first 2 doses of magrolimab should 
continue premedication with corticosteroids prior to subsequent doses at the 
investigator’s discretion.
Grade 2
Requiring symptomatic treatment 
and prophylactic medications for 
≤ 24 hours.
Interrupt magrolimab/placebo therapy per protocol and begin an IV infusion 
of normal saline and consider treating the patient with diphenhydramine 
50 mg IV (or equivalent) and/or 500 to 750 mg of oral acetaminophen.
Remain at bedside and monitor patient until resolution of symptoms.
Corticosteroid therapy may also be given at the discretion of the investigator.
If the infusion is interrupted, wait until symptoms resolve, then restart the 
infusion at 50% of the original infusion rate.
If no further complications occur after 1 hour (± 10 minutes), the rate may be 
increased to 100% of the original infusion rate. Monitor the patient closely.
If symptoms recur, stop infusion and disconnect patient from the infusion 
apparatus. No further magrolimab/placebo will be administered at that visit.
Patients who experience IRRs with the first ( x) doses of magrolimab should 
continue premedication with corticosteroids prior to subsequent doses at the 
investigator’s discretion. 
The amount of magrolimab/placebo infused must be recorded on the eCRF.
Patients who experience a Grade 2 infusion-related reaction during the 
postinfusion observation period that does not resolve to ≤ Grade 1 during that 
time should be observed until the AE resolves or stabilizes, with vital sign 
measurements as medically indicated for the management of the AE.

intervention is indicated.
Immediately discontinue infusion of magrolimab/placebo.
Begin an IV infusion of normal saline, and consider treating the patient as 
follows: Administer bronchodilators, epinephrine 0.2 to 1 mg of a 1:1000 
solution for SC administration or 0.1 to 0.25 mg of a 1:10,000 solution 
injected slowly for IV administration and/or diphenhydramine 50 mg IV with 
methylprednisolone 100 mg IV (or equivalent), as needed.
The patient should be monitored until the investigator is comfortable that the 
symptoms will not recur.
Patients who have Grade 4 infusion-related reactions will be permanently 
discontinued from study treatment. 
Patients who experience Grade 3 infusion-related reactions must be given 
premedication prior to subsequent doses. In this setting, premedication with 
oral acetaminophen (650 to 1000 mg), oral or IV diphenhydramine (25 to 
50 mg), and IV dexamethasone (4 to 20 mg), or a comparable regimen, is 
recommended for the subsequent 2 doses. Continued premedication with 
corticosteroids beyond these 2 doses may be administered at the discretion of 
the treating physician. 
Patients who receive premedication and still experience a Grade 3 
infusion-related reaction will be permanently discontinued from the study 
treatment.
For anaphylaxis, investigators should follow their institutional guidelines for 
treatment.
All patients with ≥ Grade 3 infusion-related reactions will be observed until 
the AE resolves or stabilizes, with vital sign measurements and additional 
evaluations as medically indicated for the management of the AEs.

Serious Infections
Serious infections have been reported in patients treated with magrolimab. Grades 3 and 4 
infections have been reported in patients treated with magrolimab, including fatal events of 
pneumonia and sepsis. Patients (with or without neutropenia) should be regularly monitored for 
signs and symptoms of infection. For patients with prolonged neutropenia or patients at risk, 
consider infection prophylaxis including antibiotics (e.g. fluoroquinolone) or antifungal agents 
(e.g. oral triazoles or parenteral echinocandin) in accordance with current guidelines
For serious infections, hold the next dose of magrolimab until the infection has resolved 
clinically. For serious infections that remain active for ≥ 14 days, consider discontinuation of 
magrolimab/placebo.
Dose modification guidelines for delay of azacitidine or venetoclax due to serious infections are 
provided in Section 5.5.3.2.7.

Pneumonitis
Pneumonitis has been infrequently observed in patients receiving magrolimab. Generally, 
immune-related AEs have not been observed in clinical use with magrolimab. In contrast to 
T-cell checkpoint inhibitors, magrolimab primarily exerts its antitumor efficacy through 
macrophage-mediated phagocytosis of tumor cells. Nonspecific T-cell or other host immune 
responses that are seen with T-cell checkpoint inhibitors have not been observed with 
magrolimab in nonclinical studies. Additionally, no events of macrophage activation syndrome 
or hemophagocytic lymphohistiocytosis have been reported in clinical studies.
In instances of suspected pneumonitis, first rule out non-inflammatory causes (eg, infections). If 
a non-inflammatory cause is identified, treat accordingly and continue therapy per protocol. 
Evaluate with imaging (eg, chest x-ray or computed tomography) and pulmonary consultation.
Management of potential pneumonitis is detailed in Table 11 and follows the American Society 
of Clinical Oncology (ASCO) guidelines for immune-related AEs {Brahmer 2018}. Patients who 
experience Grade 3 - 4 pneumonitis will be permanently discontinued from study treatment.

Thromboembolic Events
Thromboembolic events, including deep vein thromboses and pulmonary embolisms, have been 
reported in some patients receiving magrolimab, sometimes early in therapy. Available data for 
magrolimab do not support a clear or consistent relationship between clinical thromboembolic 
events and magrolimab use. Patients should be closely monitored for the symptoms of 
thromboembolic events and treated accordingly.
5.5.3.2.5.
Renal Abnormalities
Renal abnormalities ranging from elevated serum creatinine to renal failure have been reported 
with rare frequency in patients treated with azacitidine. In addition, renal tubular acidosis, 
defined as a decrease in serum bicarbonate to < 20 mmol/L in association with an alkaline urine 
and hypokalemia (serum potassium < 3 mmol/L), has been rarely observed. If unexplained 
reductions in serum bicarbonate (< 20 mmol/L) occur, the azacitidine dose should be reduced 
by 50% on the next cycle. Similarly, if unexplained elevations in serum creatinine or blood urea 
nitrogen to ≥ 2fold above baseline values and above the ULN occur, the next cycle should be 
delayed until values return to normal or baseline, and the azacitidine dose should be reduced 
by 50%. The reduced dose should be maintained during subsequent cycles unless toxicity 
develops. In these cases, magrolimab/placebo and venetoclax should not be dose modified or 
dose delayed.

Other Non-hematologic Toxicities 
For venetoclax related or venetoclax -related nonhematologic toxicities that are ≥ Grade 3 that do 
not resolve to  Grade 1 or baseline levels with adequate supportive care, and are clinically 
relevant, venetoclax dosing should be held until resolution to Grade 2 or lower or baseline levels. 
While venetoclax is held, magrolimab/placebo + azacitidine treatment can be continued.
For other azacitidine only related nonhematologic toxicities or nonhematological toxicities that 
do not resolve after holding venetoclax that are ≥ Grade 3 that do not resolve to  Grade 2 or 
baseline levels, azacitidine dosing should be delayed up to 14 days until resolution to  Grade 2 
or baseline levels. If ≥ Grade 3 toxicities continue despite this dose delay, dose modification of 
azacitidine should be performed in accordance with Table 12.

investigator requiring dose modifications or hold, the investigator should contact the medical 
monitor.
5.5.4.
Premedication and Prophylaxis
Premedication is required prior to the administration of the first 4 doses of magrolimab/placebo 
and in case of reintroduction with repriming. Recommended premedication should include oral 
acetaminophen, an antihistamine (IV or oral) and corticosteroid prophylaxis (IV or oral) before 

Magrolimab

the initial doses of magrolimab or in the case of repriming of magrolimab. For patients who do 
not experience an IRR with the first 2 doses of magrolimab, steroid pretreatment can be 
discontinued at investigators’ discretion. Patients who experience IRRs with the first 2 doses of 
magrolimab should continue premedication with corticosteroids prior to subsequent doses at the 
investigator’s discretion. Patients who subsequently experience any Grade 4 IRRs or recurrent 
Grade 3 IRRs after premedication with corticosteroids should be permanently discontinued from 
magrolimab treatment. 
Recommended premedications are oral acetaminophen (650 to 1000 mg), oral or IV 
diphenhydramine (25 to 50 mg), and IV dexamethasone (4 to 20 mg), or comparable regimen. If 
less than 4 hours has elapsed since a prior dose of acetaminophen has been given, the dose of 
acetaminophen premedication may be omitted.
Prior to the first dose of venetoclax, provide patients with prophylactic measures including 
adequate hydration and antihyperuricemic agents per standard of care and continue during the 
ramp-up phase (Days 1, 2, and 3).
Prophylactic antibiotics for the prevention of neutropenic fever are not required on study but may 
be administered per local institutional guidelines or investigator discretion.
5.6.
Prior and Concomitant Medications: Prohibited Concomitant Medications
Anti-leukemia therapies including chemotherapy (with the exception of hydroxyurea and/or 
leukapheresis), targeted therapies, and immunotherapy are not permitted while patients are on 
study treatment.
Live vaccines are prohibited during the study, and for 3 months after the last dose of study 
treatment {Rubin 2014}.
Premedication, as well as prophylaxis for AEs as described in Sections 5.5.3 and 5.5.4, is 
permitted while on study treatment.
Localized non-CNS radiotherapy, erythroid and/or myeloid growth factors, hormonal therapy 
with LHRH agonists for prostate cancer, hormonal maintenance therapy for breast cancers, and 
treatment with bisphosphonates RANKL inhibitors are permitted.
Red blood cell and platelet transfusions are permitted during screening and prior to enrollment to 
ensure adequate hemoglobin level according to investigators’ clinical judgment. Blood 
transfusions are also permitted during the study as clinically indicated for management of 
cytopenias and should be recorded in the electronic case report form (eCRF) dedicated to 
transfusions during the study.
Hydroxyurea and/or leukapheresis can be used throughout the study to reduce the WBC to 
≤ 20  103/µL. In nonclinical studies, co-administration of magrolimab and hydroxyurea in 
human leukemia engrafted immunodeficient mice did not cause phagocytosis of normal bone 
marrow cells, suggesting limited on-mechanism toxicity in patients. No gross safety

abnormalities were observed in these nonclinical studies. While no formal analyses have been 
performed, in clinical studies, no significant safety concerns have been observed in patients who 
have received concomitant magrolimab and hydroxyurea or magrolimab, azacitidine, and 
hydroxyurea.
All concomitant medications, including all prescription, over-the-counter, herbal supplements, 
and IV medications and fluids received within 30 days before the first dose of study treatment 
through 70-day safety follow-up calls/visits should be recorded in the eCRF.
Concomitant use of venetoclax with strong CYP3A inducers or moderate CYP3A inducers 
should be avoided, as use with a strong CYP3A inducer decreases venetoclax Cmax, which may 
decrease venetoclax efficacy.
Conversely, concomitant use of strong and moderate CYP3A inhibitors with venetoclax 
increases exposure to venetoclax and therefore may increase the risk of venetoclax-related 
toxicity including TLS. Venetoclax dose modification based on concomitant use of a strong or 
moderate CYP3A inhibitor or P-gp inhibitor at initiation, during, or after the ramp-up phase, is 
described in Table 13. Resume the venetoclax dosage that was used prior to concomitant use of a 
strong or moderate CYP3A inhibitor or P-gp inhibitor 2 to 3 days after discontinuation of the 
inhibitor. Avoid grapefruit products, Seville oranges, and starfruit during treatment with 
venetoclax, as they contain inhibitors of CYP3A.
For additional information about drug interactions with venetoclax, refer to the local prescribing 
information.

COVID 19 Vaccine
There is no contraindication to the COVID-19 vaccine with magrolimab. Given that 
immunocompromised individuals on myelosuppressive treatment may have attenuated responses 
to vaccines, investigators should, after consultation with local guidelines, consider delay of 
COVID-19 vaccination until recovery of a neutropenic individual’s absolute neutrophil count 
(ANC) and determine the ideal timing of the subsequent dose of vaccine based on count 
recovery. Investigators should document vaccinations. Investigators should notify patients of the 
risks of delaying the COVID-19 vaccination and document this along with any mitigation 
strategies for preventing COVID-19 infection.
5.7.
Accountability for Investigational Medicinal Product
The investigator is responsible for ensuring adequate accountability of all used and unused study 
drug provided by the sponsor (kits, vials, etc.). This includes acknowledgment of receipt of each 
shipment of study drug (quantity and condition). All used and unused study drug dispensed to 
patients must be returned to the site.
Each study site must keep accountability records that capture:
•
The date received and quantity of study drug (kits, vials, etc.).
•
The date, patient number, and the study drug kit and/or lot number dispensed
•
The date, quantity of used and unused study drug returned, along with the initials of the 
person recording the information, in line with local practice.
5.7.1.
Investigational Medicinal Product Return or Disposal 
Gilead recommends that used and unused study drug supplies be destroyed at the site. If the site 
has an appropriate standard operating procedure (SOP) for drug destruction as determined by 
Gilead, the site may destroy used (empty or partially empty) and unused study drug supplies in 
accordance with that site’s approved SOP. A copy of the site’s approved SOP will be obtained 
for electronic trial master file. If study drug is destroyed at the site, the investigator must 
maintain accurate records for all study drugs destroyed. Records must show the identification 
and quantity of each unit destroyed, the method of destruction, and the person who disposed of 
the study drug. Upon study completion, copies of the study drug accountability records must be 
filed at the site. Another copy will be returned to Gilead. If the site does not have an appropriate 
SOP for drug destruction, used and unused study drug supplies are to be sent to the designated 
disposal facility for destruction. The study monitor will provide instructions for return.
The study monitor will review study drug supplies and associated records at periodic intervals.
For both disposal options listed above, the study monitor must first perform drug accountability 
during an on-site monitoring visit.

Response assessments will be done in conjunction with bone marrow assessments, CBC, and 
peripheral blood smear according to the schedule of assessments (Appendix Table 1, Appendix 
Table 5). Peripheral blood smear for blasts should be done on the same day as the bone marrow 
assessment. Complete blood count results used for the response assessment will be derived from 
the best accompanying laboratory CBC result within the ± 2-week window of the bone marrow 
assessment used to support the efficacy response assessment. All components (eg, platelets, 
absolute neutrophils) should come from the same test. The date of the response will be the date 
of the bone marrow assessment. If disease progression or relapse is assessed based on CBC 
assessments or new extramedullary disease or both, other than bone marrow blasts assessments, 
then the date of the corresponding CBC or new extramedullary disease assessment date or the 
earlier of these 2 dates will be used as the date of response assessment.
6.5.1.
Bone Marrow Assessments
Bone marrow assessments (including aspirate and/or core/trephine biopsy) are required for 
response assessments (eg, blast evaluation), including conventional cytogenetic analysis per 
institutional standards (Appendix Table 1). In addition, bone marrow specimens may be used for 
biomarker studies, MRD monitoring, 
, and biobanking. Minimal residual 
disease testing and biomarker studies will be performed by a central laboratory. Details for 
preparation and distribution of aspirate and/or biopsy/trephine specimens to the testing 
laboratories will be provided in the laboratory manual for this study. Bone marrow aspirate 
and/or biopsy slides or blocks for efficacy assessments will be prepared for potential evaluation 
of response assessments by independent central review.
If the patient is cytopenic at the time of the bone marrow assessments, CBC is to be monitored at 
least twice per week for 2 weeks or until optimal count recovery is reached (whichever comes 
first).
Patients responding to initial treatment should be re-evaluated regarding their ability to undergo 
allogeneic hematopoietic cell transplant, which may cure a proportion of these patients.
Response assessment will be obtained at the EOT visit, unless a prior response assessment has 
been performed within the last 30 days or progressive disease has been documented. Response 
assessments should continue during long-term follow-up approximately every 12 weeks until the 
start of a new anti-AML therapy.
For patients who come off the study treatment to receive an SCT, follow-up for response 
assessment and collection of bone marrow aspirate results will continue until start of a new 
anti-AML therapy (except post SCT maintenance).
If a patient achieves a CR, subsequent bone marrow assessments are still required to be 
performed in accordance with the schedule of assessments.

Peripheral Blood Smear Assessment
Peripheral blood smears for blasts should be collected on the same day as the bone marrow 
aspirates for response assessment per the schedules of assessments (Appendix Table 1, Appendix 
Table 5). These samples should be collected from the arm contralateral to the arm being used for 
drug infusion/injection, if possible. Peripheral blood smears will be assessed locally.

Patient-Reported Outcomes
Four PRO instruments will be administered in this study: the EORTC QLQ-C30, the EQ-5D-5L, 
the PGIS, and the PGIC. If the PRO instruments are not available in a patient’s language, 
patients are not required to complete the assessments. Patients with other situations related to 
PRO instrument completion (eg, visual impairment/blindness, limitation in upper extremity 
mobility/dexterity) may be exempt from these assessments after discussion with the sponsor.
The patient should complete these questionnaires before any other study procedures at required 
visits. Please refer to the schedules of assessments (Appendix Table 1, Appendix Table 5) for 
timing of PRO assessments.
6.5.3.1.
EORTC QLQ-C30
The EORTC QLQ-C30 is a reliable and valid measure of PROs and has been widely used among 
cancer patients. The EORTC QLQ-C30 includes 30 separate questions (items) resulting in 
5 functional scales (physical functioning, role functioning, emotional functioning, cognitive 
functioning, and social functioning), 1 global health status scale, 3 symptom scales (fatigue, 
nausea and vomiting, and pain) and 6 single items (dyspnea, insomnia, loss of appetite, 
constipation, diarrhea, and financial difficulties) {Fayers 2001}. The recall period is 1 week 
(prior week) and it requires approximately 11 minutes to complete. An example is provided in 
Appendix 9.
6.5.3.2.
EQ-5D-5L
The EQ-5D-5L is an instrument for use as a measure of health outcome {EuroQol Research 
Foundation 2017, Janssen 2013}. The EQ-5D-5L consists of 2 sections: the EQ-5D descriptive 
system and the EQ visual analogue scale (EQ VAS). An example is provided in Appendix 10.
The descriptive system comprises 5 dimensions: mobility, self-care, usual activities, 
pain/discomfort, and anxiety/depression. Each dimension has 5 levels: no problems, slight 
problems, moderate problems, severe problems, and extreme problems. The patient is asked to 
indicate his/her health state by ticking the box next to the most appropriate statement in each of 
the 5 dimensions. This decision results in a 1-digit number that expresses the level selected for 
that dimension. The digits for the 5 dimensions can be combined into a 5-digit number that 
describes the patient’s health state.
The EQ VAS records the patient’s self-rated health on a vertical VAS, where the endpoints are 
labeled “the best health you can imagine” and “the worst health you can imagine.” The EQ VAS 
can be used as a quantitative measure of health outcome that reflects the patient’s own judgment.

PGIS/PGIC
The PGIS and PGIC assessments are both single-item assessments used to demonstrate 
sensitivity and meaningful change thresholds and bolster the validity of selected PRO 
assessments {Department for Health and Human Services (DHHS) 2018}. These questionnaires 
are provided in Appendix 11.
6.6.
Safety Assessments
Safety will be evaluated by incidence of AEs, assessment of clinical laboratory test findings 
(chemistry, hematology), physical examination, 12-lead electrocardiogram, and vital sign 
measurements.
6.6.1.
Pregnancy Test
Pregnancy tests are required only for female patients of childbearing potential. Note that a 
woman is considered to be of childbearing potential following the initiation of puberty (Tanner 
Stage 2) until becoming postmenopausal, unless permanently sterile or with medically 
documented ovarian failure. Permanent sterilization includes hysterectomy, bilateral 
oophorectomy, or bilateral salpingectomy in a female patient of any age. Women are considered 
to be in a postmenopausal state when they are ≥ 54 years of age with cessation of previously 
occurring menses for ≥ 12 months without an alternative cause. In addition, women < 54 years of 
age with amenorrhea of ≥ 12 months may also be considered postmenopausal if their follicle-
stimulating hormone level is in the postmenopausal range and they are not using hormonal 
contraception or hormonal replacement therapy. A negative serum pregnancy test is required at 
screening, and a negative urine pregnancy test is required prior to study treatment administration 
on Cycle 1 Day 1. The Cycle 1 Day 1 pregnancy test does not need to be repeated if the 
screening pregnancy test was performed within the 72 hours before study treatment 
administration. Serum or urine pregnancy tests will also be required every 4 weeks thereafter 
(Appendix Table 1, Appendix Table 5). For further details, refer to Appendix 5.
6.6.2.
Complete Blood Counts
Samples for CBC should be collected per the schedules of assessments in Appendix Table 1 and 
Appendix Table 5. White blood cell counts must be ≤ 20  103/µL prior to first dose of study 
drug and prior to each magrolimab/placebo dose for the first 4 weeks (Section 5.5). Additional 
samples for CBC may be collected outside of the protocol-specified time points to ensure WBC 
level ≤ 20  103/µL for the first cycle and repriming/re-escalation cycle. Hemoglobin must be 
checked again 3 to 6 hours after the initiation of the first and second doses of magrolimab during 
initial treatment. The patient should be transfused as clinically appropriate. Investigators should 
consider additional hemoglobin monitoring during the first week of treatment in patients with 
symptoms of anemia or at increased risk for complications of anemia.

Refer to Section 5.5.3 for detailed guidance on type and screen and DAT. Specific instructions 
for processing, labeling, and shipping samples will be provided in the central laboratory manual 
as applicable.
6.6.4.
Vital Signs
Vital signs should include heart rate, respiratory rate, oxygen saturation, blood pressure, 
temperature, and weight. Height should be recorded during screening only. Weight should be 
recorded during screening and on Day 1 of each cycle. Vital signs are to be recorded prior to 
dosing of study treatment at the visits specified in the schedules of assessments in Appendix 
Table 1 and Appendix Table 5.
6.6.5.
Physical Examination
Complete physical examination should be performed at screening. Thereafter, symptom-directed 
physical examinations are acceptable and may also include routine examination of the skin 
(including fingers, toes, and ears) and neurologic system.
6.6.6.
Electrocardiograms
A single 12-lead ECG will be performed at screening.
6.6.7.
Echocardiogram or MUGA
An echocardiogram or MUGA will be performed at screening only for patients aged 18 to 
74 years with cardiac disease, if needed to determine ineligibility to intensive chemotherapy. 
Left ventricular ejection fraction (LVEF) is to be reported in the applicable eCRF.
6.6.8.
Pulmonary Function Tests
Pulmonary function tests will be performed at screening only for patients aged 18 to 74 years 
with pulmonary disease, if needed to determine ineligibility to intensive chemotherapy. 
Diffusion capacity of lung (DLCO) or forced expiratory volume during the first second (FEV1) 
are to be reported in the applicable eCRF.
6.6.9.
Adverse Events
At each visit, all AEs observed by the investigator or reported by the patient that occur after the 
first dose of study treatment through 70 days after the last dose of study treatment are to be 
reported using the applicable eCRF (Section 7.1.1). Full details on the definitions, assessment,

Samples for PK assessment of magrolimab will be collected from all patients predose of 
magrolimab/placebo ( on the first day of the biweekly maintenance dose, an additional sample for 
postdose PK will be collected at 1 hour [ ± 15 minutes] after the end of infusion with 
magrolimab/placebo ), in accordance with the schedule of assessments (Appendix Table 1,

1rmnunoassay. 
6.8. 
Immunogenicity Assessments 
Samples for assessment of anti-magrolimab antibodies will be collected from all patients in 
accordance with the schedule of assessments (Appendix Table 1, Appendix Table 5). Antidrng 
antibody assessment will be perfonned using a validated assay following a 3-tiered approach: 
screening, confinnato1y, and titer testing. 
6.9. 
Biomarker Assessments 
Peripheral blood, bone manow aspirate, and trephine biopsy samples will be collected from all 
patients who have provided consent to pa1ticipate in this study. They may be used to evaluate the 
association of systemic and/or tissue-based biomarkers with study drng response, including 
efficacy and/or AEs, dose optimization, and to better understand the biology of AML in general. 
Because biomarker science is a rapidly evolving area of investigation, and AEs in paiticular ai·e 
difficult to predict, it may not be possible to specify prospectively all tests that may be done on 
the specimens provided. The specific analyses will include, but may not be limited to, the 
biomai·kers and assays described below. The testing outlined below is based upon the cmTent 
state of scientific knowledge. It may be modified during or after the end of the study to remove 
tests no longer indicated and/or to add new tests based upon new state of the ait knowledge. 
Blood and bone manow samples will be collected to measure biomai·kers, which may include 
but will not be limited to the presence of or changes to irmnune cell populations, secreted protein 
factors, the expression of cell surface mai·kers on either tumor cells or cells of the tumor 
microenvirorunent, and genetic mutations in tumor cells or subclones of tumor cells at the time 
points listed in the schedules of assessments (Appendix Table 1, Appendix Table 5).

These samples will also be used for genomic research to identify or validate genetic markers that 
may increase our knowledge and understanding of the biology of the study disease and related 
diseases, and to study the association of genetic markers with disease pathogenesis, progression 
and/or tr·eatment outcomes, including efficacy, AEs, and the processes of dmg absmption and 
disposition. These specimens may also be used to develop biomarker or diagnostic assays and 
establish the perfo1mance characteristics of these assays. Genomics research may include 
sequencing of genetic material derived from both cancer cells and nonnal cells. Sequencing of 
genetic material derived from cancer cells will be used to better understand the MOA of 
magrolimab combinations in this patient population, and potentially to identify subsets of 
patients who are likely to benefit. Sequencing of genetic material derived from n01mal cells will 
be used to define differences in sequence that are cancer specific. 
Samples collected for biomarker assessments will be desh'oyed no later than 15 years after the 
end of study or per country requirements. Specific instr11ctions for processing, labeling, and 
shipping samples will be provided in the cenh'al laborato1y manual. 
6.9.1. 
Minimal Residual Disease 
Sensitive flow cytometry-based assays are capable of identifying phenotypic leukemia cells 
down to frequencies of less than 1 x 10-3 of total WBCs. These rare leukemia cells are tenned 
MRD, and their presence or absence following h'eatment is an independent prognostic factor for 
disease progression and relapse in all AML tr·eatment paradigms. Patients with AML in this h'ial 
will be assessed by a flow cytometry-based assay for MRD in their bone maITow at multiple time 
points before and after h'eatment during the first 6 c des in order to fmiher understand the 
efficac and MOA of ma ·olimab combinations. 
this study, patients will be tested by both methods, 
and the sensitivity and concordance of the 2 methods may be assessed. Specific instructions for 
processing, labeling, and shipping samples will be provided in the centr·al laborato1y manual. 
6.9.2. 
Leukemia Mutation Profiles and Burden 
The pathogenesis of all cancers, including leukemias, has a basis in their acquired genetic 
mutations. The paiiicular genetic mutations present in a patient's cancer may render it sensitive 
or resistant to anti-cancer therapies, including magrolimab-based combinations. In some cases, if 
str·ongly associated with clinical benefit or the MOA of a dmg, these genetic mutations can be 
used to select patients who ai·e eligible for a given h'eatment. In other cases, the total number of 
mutations present in the genome of a given cancer ( eg, rather than the specific genes mutated) 
can be coITelated with likelihood of response, such as is the case with some T-cell checkpoint 
therapies. Clonal evolution of leukemia cells will also be tr·acked while on h'eatment and at the 
time of relapse, in order to understand the mechanism of resistance to magrolimab combinations.

Changes in Immune Effector Cell Composition 
Final 
Amendment 7 
Activation of the immune system can be associated with changes in immune effector cell 
frequency or localization to the tumor microenvironment. In order to explore changes in the 
composition of immune effector cells to infonn MOA, patients with AML in this trial will be 
assessed by methods potentially including, but not limited to, multiplex immunofluorescence and 
single-cell RNA sequencing at multiple pre- and postti·eatment time points. 
6.9.4. 
Changes in Immune Effector Cell Signaling Molecules 
Activation of the immune system can be associated with changes in expression or secretion of 
immune-regulato1y molecules, including cytokines, chemokines, and others. Release of such 
molecules, and their concenti·ation in the peripheral blood or tumor microenvironment can 
info1m MOA. Patients with AML in this u-ial will be assessed for soluble protein factors in the 
peripheral plasma and/or bone maiTow by methods potentially including, but not limited to, 
multiplex enzyme-linked immunosorbent assay or aptamer-based measurement. 
6.9.5. 
Expression of Prophagocytic and Antiphagocytic Signals by Leukemia Cells 
Preclinical studies suggest that the efficacy of magrolimab depends on the balance of pro- and 
antiphagocytic signals expressed by cancer cells. Magrolimab combination therapies, including 
those investigated as pait of this clinical ti·ial, may derive their efficacy from the simultaneous 
blockade of antiphagocytic signals by magrolimab, and the increased expression of 
prophagocytic signals by the companion diug. In order to better define the efficacy and MOA of 
magrolimab combinations in AML, the surface profile of known pro- and antiphagocytic signals 
will be assessed on leukemic cells at multiple pre- and postti·eatment time points using methods 
to include, but not be limited to, flow cytometiy, mass cytometiy , and multiplex 
immunofluorescence.

Assessments for Early Discontinuation from Study Treatment 
If a patient discontinues study dosing ( eg, as a result of an AE), eve1y attempt should be made to 
keep the patient in the study and continue to perfo1m the required study-related follow-up and 
procedures (Section 6.11.1 ). If this is not possible or acceptable to the patient or investigator, the 
patient may be withdrawn from the study. For patients who discontinue from the study prior to 
completion of all protocol-required visits for study assessments or survival follow-up (Appendix 
Table 5), the investigator may search publicly available records (where pe1mitted by local laws 
and regulations) to asce1tain survival status. This ensures reduced risk of missing critical efficacy 
data.

ADVERSE EVENTS AND TOXICITY MANAGEMENT
7.1.
Definitions of Adverse Events and Serious Adverse Events
7.1.1.
Adverse Events
An AE is any untoward medical occurrence in a clinical study patient administered a study drug 
that does not necessarily have a causal relationship with the treatment. An AE can therefore be 
any unfavorable and/or unintended sign, symptom, or disease temporally associated with the use 
of a study drug, whether or not the AE is considered related to the study drug. Adverse events 
may also include pretreatment or posttreatment complications that occur as a result of protocol-
specified procedures or special situations (Section 7.1.3).
An AE does not include the following:
•
Medical or surgical procedures such as surgery, endoscopy, tooth extraction, and transfusion. 
The condition that led to the procedure may be an AE and must be reported
•
Preexisting diseases, conditions, or laboratory abnormalities present or detected before the 
screening visit that do not worsen
•
Situations where an untoward medical occurrence has not occurred (eg, hospitalization for 
elective surgery, social and/or convenience admissions)
•
Overdose without clinical sequelae (Section 7.1.3)
•
Any medical condition or clinically significant laboratory abnormality with an onset date 
before the ICF is signed and not related to a protocol-associated procedure is not an AE but 
rather considered to be preexisting and should be documented as medical history.
Preexisting events that increase in severity or change in nature after study drug initiation or 
during or as a consequence of participation in the clinical study will also be considered AEs.
7.1.2.
Serious Adverse Events
An SAE is defined as an event that, at any dose, results in the following:
•
Death
•
A life-threatening situation (Note: The term “life-threatening” in the definition of “serious” 
refers to an event in which the patient was at risk of death at the time of the event; it does not 
refer to an event that hypothetically might have caused death if it were more severe.)
•
In-patient hospitalization or prolongation of existing hospitalization

Magrolimab
Protocol GS-US-590-6154

Gilead Sciences, Inc.
Amendment 7
CONFIDENTIAL
Page 91
15 December 2023
•
Persistent or significant disability/incapacity
•
A congenital anomaly/birth defect
•
A medically important event or reaction: Such events may not be immediately 
life-threatening or result in death or hospitalization but may jeopardize the patient or may 
require intervention to prevent one of the other outcomes constituting SAEs. Medical and 
scientific judgment must be exercised to determine whether such an event is a reportable 
under expedited reporting rules. Examples of medically important events include intensive 
treatment in an emergency room or at home for allergic bronchospasm; blood dyscrasias or 
convulsions that do not result in hospitalization; and development of drug dependency or 
drug abuse.
7.1.2.1.
Protocol-Specific Serious Adverse Event Definitions
Given the primary and secondary endpoints of the study, in order to maintain study integrity, the 
following events that are assessed as unrelated to study drug will not be considered AEs/SAEs:
•
Progression of AML
•
Deaths related to progression of AML
Events that are considered to represent progression of the underlying AML should not be 
recorded as AEs/SAEs. These data will be captured as efficacy assessment data only. If there is 
any uncertainty as to whether an event is due to disease progression, it should be reported as an 
AE/SAE.
Death that is attributed by the investigator as solely due to progression of AML and that occurs 
during the protocol-specified AE reporting period should be recorded only on the death eCRF 
(ie, not collected as an SAE on the AE eCRF).
7.1.2.1.1.
Deaths not related to AML progression
All other deaths (ie, deaths that are not due to AML progression) occurring during the protocol-
specified AE reporting period, regardless of attribution, will be recorded on the AE eCRF and 
reported within 24 hours of awareness and no later than the next business day.
When recording a death on the eCRF, the event or condition that is considered the primary cause 
of death should be the AE term, and the outcome should be fatal. A patient can only have 1 AE 
(SAE) with a fatal outcome and severity of CTCAE Grade 5.
7.1.3.
Study Drugs and Gilead Concomitant Therapy Special Situations Reports
Special situation reports (SSRs) include all reports of medication error, abuse, misuse, overdose, 
occupational exposure, drug interactions, exposure via breastfeeding, unexpected benefit, 
transmission of infectious agents via the product, counterfeit of falsified medicine, and 
pregnancy regardless of an associated AE.

Page 92
15 December 2023
Medication error is any unintentional error in the prescribing, dispensing, preparation for 
administration or administration of a study drug while the medication is in the control of a health 
care professional, patient, or consumer. Medication errors may be classified as a medication error 
without an AE, which includes situations of missed dose, medication error with an AE, 
intercepted medication error, or potential medication error.
Abuse is defined as persistent or sporadic intentional excessive use of a study drug by a patient.
Misuse is defined as any intentional and inappropriate use of a study drug that is not in 
accordance with the protocol instructions or the local prescribing information.
An overdose is defined as an accidental or intentional administration of a quantity of a study 
drug given per administration or cumulatively that is above the maximum recommended dose as 
per protocol or in the product labelling (as it applies to the daily dose of the patient in question). 
In cases of a discrepancy in drug accountability, overdose will be established only when it is 
clear that the patient has taken the excess dose(s). Overdose cannot be established when the 
patient cannot account for the discrepancy, except in cases in which the investigator has reason 
to suspect that the patient has taken the additional dose(s).
Occupational exposure is defined as exposure to a study drug as a result of one’s professional or 
nonprofessional occupation.
Drug interaction is defined as any drug/drug, drug/food, or drug/device interaction.
Unexpected benefit is defined as an unintended therapeutic effect of which the results are judged 
to be desirable and beneficial.
Transmission of infectious agents is defined as any suspected transmission of an infected agent 
through a Gilead study drug.
Counterfeit or falsified medicine: Any study drug with a false representation of (a) its identity, 
(b) its source, or (c) its history.
7.2.
Assessment of Adverse Events and Serious Adverse Events
The investigator or qualified subinvestigator is responsible for assessing AEs and SAEs for 
causality and severity, and for final review and confirmation of accuracy of event information 
and assessments.
7.2.1.
Assessment of Causality for Study Drugs, Authorized Auxiliary Medical 
Products, and Procedures 
The investigator or qualified subinvestigator is responsible for assessing the relationship to study 
drug using clinical judgment and the following considerations:
•
No: Evidence exists that the AE has an etiology other than the study drug. For SAEs, an 
alternative causality must be provided (eg, preexisting condition, underlying disease, 
intercurrent illness, concomitant medication).
•
Yes: There is reasonable possibility that the AE may have been caused by the study drug.

Gilead Sciences, Inc.
Amendment 7
CONFIDENTIAL
Page 93
15 December 2023
It should be emphasized that ineffective treatment should not be considered as causally related in 
the context of AE reporting.
The relationship to study procedures (eg, invasive procedures such as venipuncture or biopsy) 
should be assessed using the following considerations:
•
No: Evidence exists that the AE has an etiology other than the study procedure.
•
Yes: The AE occurred as a result of protocol procedures (eg, venipuncture).
When there is a reasonable possibility that the causality of the AE/SAE can be assigned to the 
authorized AxMP, the investigator or qualified subinvestigator will need to report the causality 
assessment for the authorized AxMP(s) in accordance with the eCRF. 
7.2.2.
Assessment of Severity
The severity of AEs will be graded using the NCI CTCAE Version 5.0. For each episode, the 
highest grade attained should be reported as defined in the Toxicity Grading Scale (Appendix 6).
7.3.
Investigator Reporting Requirements and Instructions
7.3.1.
Requirements for Collection Prior to Study Drug Initiation
After informed consent, but prior to initiation of study medication, the following types of events 
must be reported on the applicable eCRFs: all SAEs and AEs related to protocol-mandated 
procedures.
7.3.2.
Adverse Events
Following initiation of study medication, all AEs, regardless of cause or relationship, will be 
collected until 70 days after last administration of study drug and reported on the eCRFs as 
instructed.
All AEs should be followed until resolution or until the AE is stable, if possible. Gilead may 
request that certain AEs be followed beyond the protocol-defined follow-up period.
7.3.3.
Serious Adverse Events
All SAEs, regardless of cause or relationship, that occur after the patient first consents to 
participate in the study (ie, signing the ICF) and throughout the duration of the study, including 
the posttreatment follow-up visit, must be reported on the applicable eCRFs and PS as instructed 
below in this section. This also includes any SAEs resulting from protocol-associated procedures 
performed after the ICF is signed.
Any SAEs and deaths that occur after the posttreatment follow-up visit but within 70 days of the 
last dose of study drug, regardless of causality, should also be reported.

Investigators are not obligated to actively seek SAEs after the protocol-defined follow-up period; 
however, if the investigator learns of any SAEs that occur after the protocol-defined follow-up 
period has concluded and the event is deemed relevant to the use of study drug, the investigator 
should promptly document and report the event to Gilead PS.
Instructions for reporting SAEs are described in Section 7.4.1.
7.3.4.
Study Drug Special Situations Reports
All study drug SSRs that occur from study drug initiation and throughout the duration of the 
study, including the posttreatment follow-up visit, must be reported to Gilead PS (Section 7.4.2). 
Adverse events and SAEs resulting from SSRs must be reported in accordance with the AE and 
SAE reporting guidance (Section 7.4).
7.3.5.
Concomitant Therapy Reports
7.3.5.1.
Gilead Concomitant Therapy Special Situations Report
Special situation reports involving a Gilead concomitant therapy (not considered study drug), 
that occur after the patient first consents to participate in the study (ie, signing the ICF) and 
throughout the duration of the study, including the posttreatment follow-up visit, must be 
reported to Gilead PS utilizing the paper SSR (Section 7.4.2.2).
7.3.5.2.
Non-Gilead Concomitant Therapy Report
Special situations involving non-Gilead concomitant medications do not need to be reported on 
the SSR form; however, for special situations that result in AEs due to a non-Gilead concomitant 
medication, the AE should be reported on the AE form.
Any inappropriate use of concomitant medications prohibited by this protocol should not be 
reported as “misuse,” but may be more appropriately documented as a protocol deviation.
All clinical sequelae in relation to these SSRs will be reported as AEs or SAEs at the same time 
using the AE eCRF and/or the SAE report form. Details of the symptoms and signs, clinical 
management, and outcome will be reported, when available.

Reporting Process for Serious Adverse Events and Special Situation Reports
7.4.1.
Serious Adverse Event Reporting Process
•
For fatal or life-threatening events, copies of hospital case reports, autopsy reports, and other 
documents are also to be transmitted by email or fax when requested and applicable. 
Transmission of such documents should occur without personal patient identification, 
maintaining the traceability of a document to the patient identifiers.
•
Additional information may be requested to ensure the timely completion of accurate safety 
reports.

Any medications necessary for treatment of the SAE must be recorded onto the concomitant 
medication section of the patient’s eCRF and the SAE narrative section of the Safety Report 
Form eCRF.
7.4.1.1.
Electronic Serious Adverse Event Reporting Process
•
Site personnel will record all SAE data on the applicable eCRFs and from there transmit the 
SAE information to Gilead PS within 24 hours of the investigator’s knowledge of the event 
from ICF signature throughout the duration of the study, including the protocol-required 
posttreatment follow-up period.
•
If it is not possible to record and transmit the SAE information electronically, record the SAE 
on the paper SAE reporting form and transmit within 24 hours:
Gilead PS
Email: Safety_FC@gilead.com
or
Fax: 1-650-522-5477
•
If an SAE has been reported via a paper form because the eCRF database has been locked, no 
further action is necessary. If the database is not locked, any SAE reported via paper must be 
transcribed as soon as possible on the applicable eCRFs and transmitted to PS.
7.4.2.
Special Situations Reporting Process 
7.4.2.1.
Paper Special Situations Reporting Process for Study Drug
•
All SSRs will be recorded on the special situations report form and transmitted by emailing 
or faxing the report form within 24 hours of the investigator’s knowledge of the event to the

the pregnancy. Contact details for transmitting the pregnancy report form are as follows:
Gilead PS
Email: Safety_FC@gilead.com
or
Fax: 1-650-522-5477
•
The pregnancy itself is not considered an AE, nor is an induced elective abortion to terminate 
a pregnancy without medical reasons.
•
All other premature terminations of pregnancy (eg, a spontaneous abortion, an induced 
therapeutic abortion due to complications or other medical reasons) must be reported within 
24 hours as an SAE, as described in Section 7.4.1. The underlying medical reason for this 
procedure should be recorded as the AE term.
•
A spontaneous abortion is always considered to be an SAE and will be reported as described 
in Section 7.4.1. Furthermore, any SAE occurring as an adverse pregnancy outcome post 
study must be reported to the Gilead PS.
•
The patient should receive appropriate monitoring and care until the conclusion of the 
pregnancy. The outcome of the pregnancy should be reported to Gilead PS using the 
pregnancy outcome report form. If the end of the pregnancy occurs after the study has been 
completed, the outcome should be reported directly to Gilead PS. Gilead PS contact 
information is as follows: email: Safety_FC@gilead.com and fax: +1 (650) 522-5477.

In accordance with the European Union Clinical Trials Directive (2001/20/EC), Gilead or a 
specified designee will notify worldwide regulatory agencies and the relevant IEC in concerned 
Member States of applicable SUSARs as outlined in current regulations.
Assessment of expectedness for SAEs will be determined by Gilead using reference safety 
information specified in the IB or relevant local label as applicable.
All investigators will receive a safety letter notifying them of relevant SUSAR reports associated 
with any study drug. The investigator should notify the IRB or IEC of SUSAR reports as soon as 
is practical, where this is required by local regulatory agencies, and in accordance with the local 
institutional policy.
7.6.
Clinical Laboratory Abnormalities and Other Abnormal Assessments as 
Adverse Events or Serious Adverse Events
Laboratory abnormalities without clinical significance are not to be recorded as AEs or SAEs. 
However, laboratory abnormalities (eg, clinical chemistry, hematology, urinalysis) that require 
medical or surgical intervention or lead to study drug interruption, modification, or 
discontinuation must be recorded as an AE, as well as an SAE, if applicable. In addition, 
laboratory or other abnormal assessments (eg, electrocardiogram, x-rays, vital signs) that are 
associated with signs and/or symptoms must be recorded as an AE or SAE if they meet the 
definition of an AE or SAE as described in Sections 7.1.1 and 7.1.2. If the laboratory 
abnormality is part of a syndrome, record the syndrome or diagnosis (eg, anemia), not the 
laboratory result (ie, decreased hemoglobin).
Severity should be recorded and graded according to the NCI CTCAE Version 5.0. For AEs 
associated with laboratory abnormalities, the event should be graded on the basis of the clinical 
severity in the context of the underlying conditions; this may or may not be in agreement with 
the grading of the laboratory abnormality.
7.7.
Abnormal Liver Function Tests
Liver toxicity will be evaluated for all patients.
In the absence of an explanation for increased liver function tests, such as viral hepatitis, 
pre-existing or acute liver disease, or exposure to other agents associated with liver injury, the 
patient may be discontinued from the study treatment if the investigator determines that it is not 
in the patient’s best interest to continue. Discontinuation of treatment should be considered if 
there is an indication of severe liver injury according to Hy’s Law, defined by US FDA 
Guidance for Industry, Drug-Induced Liver Injury: Premarketing Clinical Evaluation {U.S. 
Department of Health and Human Services 2009} as:
• Treatment-emergent ALT or AST elevation (≥ 3  ULN), AND 
• Treatment-emergent total bilirubin elevation (> 2  ULN), and absence of cholestasis (defined 
as ALP < 2  ULN), AND 
• No other good explanation for the injury (hepatitis A, B, C, or other viral hepatic injury, 
alcohol ingestion, congestive heart failure, worsening liver metastases).

STATISTICAL CONSIDERATIONS
8.1.
Analysis Objectives and Endpoints
The study objectives are provided in Section 2.
8.1.1.
Definition of Primary Efficacy Endpoint
8.1.1.1.
Overall Survival
Overall survival is measured from the date of randomization to the date of death from any cause. 
Patients whose deaths are not observed during the study will be censored at their last known 
alive date.
8.1.2.
Definition of Secondary Efficacy Endpoints
8.1.2.1.
Rate of CR + CRh Within 6 Cycles of Treatment
The CR + CRh rate is the proportion of patients who achieve a CR (including CRMRD- and 
CRMRD+/unk) or CRh as defined by CR with partial platelet and absolute neutrophil count recovery 
(Appendix 4) within 6 cycles of treatment while on study prior to initiation of any new anti-AML 
therapy or SCT.
8.1.2.2.
Rate of CR Within 6 Cycles of Treatment
The CR rate is the proportion of patients who achieve a CR, including CRMRD- and CR with 
positive or unknown minimal residual disease (CRMRD+/unk) within 6 cycles of treatment, as 
determined by investigators based on the ELN 2017 for AML {Dohner 2017} with modifications 
(Appendix 4) while on study prior to initiation of any new anti-AML therapy or SCT.
8.1.2.3.
Event-Free Survival
Event-free survival is defined as time from the date of randomization to the earliest date of the 
documented relapse from CR, treatment failure (defined as failure to achieve CR within 6 cycles 
of treatment), or death from any cause. Response assessments or death post SCT or new 
anti-AML therapies will be included in the analysis. The date of randomization will be assigned 
as the event date for patients with treatment failure.
Patients who are not observed to have one of the specified events on or prior to data cutoff date 
(the date on which subsequently collected data will not be considered as part of the analysis) will 
be censored at the date of their last response assessment with clear documentation of no relapse 
on or prior to the data cutoff date. Patients will be censored at the date of randomization if no 
response assessment is performed after randomization and the patients do not die.

8.1.2.4.
Duration of CR + CRh
The duration of CR + CRh is measured from the time the assessment criteria are first met for CR 
(including CRMRD- and CRMRD+/unk) or CRh within 6 cycles of treatment until the first date of 
AML relapse or death (including assessments post SCT). Those who are not observed to have 
relapsed disease or death while on study will be censored at the date of their last response 
assessment with no evidence of relapse on or prior to the data cutoff date. If patients start taking 
new anti-AML therapies (excluding post-SCT maintenance therapy) before relapse, duration of 
CR + CRh will be censored at the last response assessment before the initiation of the new 
anti-AML therapies.
8.1.2.5.
Duration of CR
The DCR is measured from the time the assessment criteria are first met for CR (including 
CRMRD- and CRMRD+/unk) within 6 cycles of treatment until the first date of AML relapse or death 
(including assessments post SCT). Those who are not observed to have relapsed disease or death 
while on study will be censored at the date of their last response assessment with no evidence of 
relapse on or prior to the data cutoff date. If patients start taking new anti-AML therapies 
(excluding post-SCT maintenance therapy) before relapse, DCR will be censored at the last 
response assessment before the initiation of the new anti-AML therapies.
8.1.2.6.
Rate of CR/CRhMRD- Within 6 Cycles of Treatment
The CR/CRhMRD- rate is the proportion of patients who achieve a CRMRD- or CRhMRD- within 
6 cycles of treatment while on study prior to initiation of any new anti-AML therapy or SCT. 
The threshold for MRD negativity in this study is a frequency of less than 1  10-3 phenotypic 
leukemic cells per total WBCs.
8.1.2.7.
Rate of CRMRD- Within 6 Cycles of Treatment
The CRMRD- rate is the proportion of patients who achieve a CRMRD- within 6 cycles of treatment, 
as determined by investigators based on the ELN 2017 for AML with modifications (Appendix 
Table 6), while on study prior to initiation of any new anti-AML therapy or SCT. The threshold 
for MRD negativity in this study is a frequency of less than 1  10-3 phenotypic leukemic cells 
per total WBCs.
8.1.2.8.
Transfusion Independence Conversion Rate
The transfusion independence conversion rate includes both RBC transfusion independence rate 
and platelet transfusion independence rate.
The RBC transfusion independence conversion rate is the proportion of patients who have a 
56-day or longer period with no RBC or whole blood transfusions at any time between the date 
of first dose of study treatment and discontinuation of study treatment among all patients who are 
RBC transfusion dependent at baseline. The RBC transfusion dependence at baseline is defined 
as having received an RBC or whole blood transfusion within the 28 days prior to the first dose 
of study treatment.

The platelet transfusion independence conversion rate is the propo1iion of patients who have a 
56-day or longer period with no platelet transfusions at any time between the date of first dose of 
study treatment and discontinuation of study treatment among all patients who are platelet 
transfusion dependent at baseline. Platelet transfusion dependence at baseline is defined as 
having received a platelet transfusion within the 28 days prior to the first dose of study treatment. 
8.1.2.9. 
Time to First Deterioration on the EORTC QLQ-C30 GHS/QoL Scale 
The TTD on the EORTC QLQ-C30 GHS/QoL scale is defined as time from the date of 
randomization to the time a patient experienced at least 1 threshold value deterioration from 
baseline or death, whichever is earlier. 
8.1.2.10. 
Time to First Deterioration on the EORTC QLQ-C30 Physical Functioning Scale 
The TTD on the EORTC QLQ-C30 physical functioning scale is defined as time from the date of 
randomization to the time a patient experienced at least 1 threshold value deterioration from 
baseline or death, whichever is earlier.

Planned Analyses 
Interim Analyses 
There will be 2 planned interim analyses for OS. 
8.2.1.1. 
First Interim Analysis 
Final 
Amendment 7 
The first interim analysis will be perfonned when approximately 121 deaths (40% of the 
expected 303 deaths) have occun ed, outstanding data queries have been resolved or adjudicated 
as unresolvable, and the data have been cleaned and finalized. An administrntive I-sided alpha = 
0.0001 is allocated to this interim analysis. The nonbinding futility analysis with a futility 
boundaiy of HR = 1.1 will be perfo1med. A Gamma beta-spending function with parameter -5 is 
used to obtain the futility boundai·ies for both interim analysis. 
8.2.1.2. 
Second Interim Analysis 
The second interim analysis will be conducted when approximately 227 deaths (75% of the 
expected 303 deaths) have occuned, outstanding data queries have been resolved or adjudicated 
as unresolvable, and the data have been cleaned and finalized. One-sided a = 0.0249 will be 
allocated to the analysis of OS and key secondaiy endpoints in the second interim analysis and 
primaiy analysis. 
The Lan-DeMets approach with O'Brien-Fleming type alpha spending function will be used for 
the interim analysis and primaiy analysis for OS. The stopping boundaries at each analysis time 
are provided in Table 16. If the null hypothesis of OS is not rejected in the second interim 
analysis, the second nonbinding futility test with a futility boundaiy of HR = 0.9 will be 
perfo1med.

To strongly control the overall type I error across the testing of the primary and key secondary 
efficacy endpoints, a hierarchical testing strategy will be performed with a predefined order as 
listed in the protocol and the statistical analysis plan (SAP). The primary efficacy endpoint of OS 
will be tested for superiority first at the significance level specified in Table 16. If the superiority 
is established, analysis of key secondary efficacy endpoints for superiority will be performed. 
For each key secondary endpoint, an O'Brien-Fleming boundary will be derived based on the 
information fraction defined at the interim analysis and the remaining type I error, respectively, 
per Table 17.
The information fraction of EFS at the second interim analysis is calculated based on the 
assumption that median EFS is 9.8 months in patients treated with placebo + venetoclax + 
azacitidine and HR of 0.7. Approximately 292 and 358 EFS events will be observed at the 
second interim and primary analysis per efficacy and enrollment assumptions, respectively, so 
the information fraction is 82% (292/358) at the second interim analysis.

At the time of each interim analysis, the DMC will review the unblinded analysis results, and 
provide recommendations. The process details are described in Section 5.1.3 and 8.13.
8.2.1.3.
Data Monitoring Committee Analysis
In addition to the 2 planned interim efficacy analyses, the DMC will convene to review safety 
analysis results periodically.
8.2.2.
Interim Analysis Communication Plan
An interim analysis communication plan describing the processes and procedures that will be 
employed in conducting the prespecified interim efficacy analysis and the controlled 
dissemination of the resulting interim analysis data will be developed and finalized separately. 
The unblinding of specific Gilead personnel will be documented in accordance with the 
appropriate SOPs.
8.2.3.
Primary Analysis
If the null hypothesis on OS is not rejected in the second interim analysis, the unblinded primary 
analysis will be conducted when 303 deaths have occurred. The analysis will be conducted after 
all outstanding data queries have been resolved or adjudicated as unresolvable, and the data have 
been cleaned and finalized for the analysis. This analysis of the primary endpoint of OS and key 
secondary endpoints will serve as the final analysis for these endpoints and will be used to 
evaluate the efficacy and safety of magrolimab versus placebo in combination with venetoclax 
and azacitidine.
If the null hypothesis of OS is rejected in the second interim analysis, the primary analysis 
timing will be determined by the maturity of the key secondary endpoints that have not been 
rejected in the second interim analysis.
8.2.4.
Final Analysis
The final analysis will be performed after all patients have completed the study, outstanding data 
queries have been resolved or adjudicated as unresolvable, and the data have been cleaned and 
finalized.

Analysis Conventions
8.4.1.
Analysis Sets
8.4.1.1.
Efficacy
The primary analysis set for efficacy analysis is the Intent-to-Treat (ITT) analysis set, defined as 
all randomized patients according to the treatment arm to which the patients are randomized, 
unless otherwise specified.
The Per-Protocol (PP) Analysis Set will be used in sensitivity analysis of the primary and key 
secondary efficacy endpoints. The PP Analysis Set includes patients in the ITT Analysis Set who 
meet the general criteria defining the target population, are adherent to the protocol, are 
compliant with study drug treatment, and are evaluable for relevant efficacy endpoints. Study 
drug assignment will be designated according to the actual treatment received. The determination 
criteria details of the PP Analysis Set will be listed in the SAP.
8.4.1.2.
Safety
The primary analysis set for safety analysis is the Safety Analysis Set, defined as all patients who 
received at least 1 dose of any study treatment, with treatment assignments designated according 
to the actual treatment received.
All data collected during treatment period up to the last dose plus 70 days will be included in the 
safety summaries.
8.4.1.3.
Pharmacokinetics
The PK analysis will be conducted on Pharmacokinetic Analysis Set, defined as all randomized 
patients who received at least 1 dose of magrolimab and have at least 1 measurable posttreatment 
serum concentration of magrolimab.
8.4.1.4.
Immunogenicity
The Immunogenicity Analysis Set is defined as all randomized patients who received at least 
1 dose of magrolimab and had at least 1 evaluable anti-magrolimab antibody test result.

8.4.2.
Data Handling Conventions
By-patient listings will be created for important variables from each eCRF module. Summary 
tables for continuous variables will contain the following statistics: N (number in analysis set), n 
(number with data), mean, standard deviation, 95% CIs on the mean, median, minimum, and 
maximum. Summary tables for categorical variables will include: N, n, percentage, and 95% CIs 
on the percentage. Unless otherwise indicated, 95% CIs for binary variables will be calculated 
using the binomial distribution (exact method) and will be 2-sided. Data will be described and 
summarized by treatment arm.
The baseline value used in each analysis will be the last (most recent) pretreatment value before 
or on the first dosing date of study treatment. As appropriate, changes from baseline to each 
subsequent time point will be described and summarized. Similarly, as appropriate, the best 
change from baseline during the study will also be described and summarized. Graphical 
techniques (ie, waterfall plots, Kaplan-Meier curves, line plots) may be used when such methods 
are appropriate and informative. Analysis will be based upon the observed data unless methods 
for handling missing data are specified. If there is a significant degree of non-normality, analysis 
may be performed on log-transformed data or nonparametric tests may be applied, as

Demographic and Baseline Characteristics Analysis
Demographic and baseline measurements will be summarized using standard descriptive 
methods.
Demographic summaries will include age, sex, race/ethnicity, and randomization stratification 
group. Baseline data will include a summary of weight, height, body surface area, body mass 
index, WHO AML classification, and ECOG performance status.

Efficacy Analysis
8.6.1.
Analysis of Primary Endpoint
Formal hypothesis testing will be performed to test the statistical hypothesis that the distribution 
of OS between the experimental arm and the control arm is the same (null hypothesis) versus that 
the experimental arm is superior to the control arm in terms of survival function (alternative 
hypothesis).
A log-rank test stratified by the randomization stratification factors will be used to compare the 
treatment arms for OS. A stratified Cox proportional hazard regression model will be used to 
estimate HR and its 2-sided 95% CI. In addition, the Kaplan-Meier method will be used to 
estimate median OS with its 95% CI, and the Kaplan-Meier plots will be provided.

To assess the robustness of the primary endpoint analysis results, OS will also be compared 
between treatment arms in the PP Analysis Set.
8.6.2.
Analysis of Secondary Endpoints
Analysis will be performed based on the patient populations on which the endpoints are defined. 
Analysis of EFS will be similar to that of the primary efficacy endpoint OS.
Formal hypothesis testing will be performed to test the statistical hypothesis that the CR + CRh 
rates of the experimental arm and control arm are the same (null hypothesis) versus that the 
experimental arm is superior to the control arm in terms of CR + CRh rate (alternative 
hypothesis).
The Cochran-Mantel-Haenszel test stratified by the randomization stratification factors will be 
used to test whether CR + CRh rates of the 2 arms are the same. The point estimate of the CR + 
CRh rate and the corresponding 2-sided exact 95% CI based on Clopper-Pearson method will be 
provided for each treatment arm.
The CR rate, CR/CRhMRD- rate, CRMRD- rate and transfusion independence conversion rate will 
be evaluated in a similar manner as CR + CRh rate, except that the transfusion independence 
conversion rates will be based on the subset of randomized patients who are transfusion-
dependent at baseline.
For the time-to-event endpoints of DCR and duration of CR + CRh, analysis will be conducted 
based on the subsets on which the outcome measures are defined. Specifically, the DCR will be 
based on patients who achieved CR within 6 cycles of treatment. Duration of CR + CRh will be 
based on patients who achieved CR or CRh within 6 cycles of treatment. The Kaplan-Meier 
method will be used to estimate median duration with its 95% CI and Kaplan-Meier plots will be 
provided.
To assess the robustness of the analysis results, key secondary efficacy endpoints will also be 
analyzed in the PP Analysis Set.
8.7.
Safety Analysis
All safety data collected on or after the date that study drug was first dispensed up to the date of 
last dose of study drug plus 70 days will be summarized by treatment group (according to the 
study drug received). Data for the pretreatment and treatment-free safety follow-up periods will 
be included in data listings. For categorical safety data, including incidence of AEs and 
categorizations of laboratory data, count and percent of patients will be summarized. For 
continuous safety data, including laboratory data, the number of patients, mean, standard 
deviation, minimum, quartiles, median, and maximum will be summarized by treatment group. 
Details are noted below.

Extent of Exposure
A patient’s extent of exposure to study drug data will be generated from the study drug 
administration data. Exposure data will be summarized by treatment group.
8.7.2.
Adverse Events
Clinical and laboratory AEs will be coded using the Medical Dictionary for Regulatory 
Activities (MedDRA). System organ class, high-level group term, high-level term, preferred 
term, and lower-level term will be attached to the clinical database.
Events will be summarized on the basis of the date of onset for the event. A treatment-emergent 
AE will be defined as any AE that begins on or after the date of first dose of study treatment up 
to the date of last dose of study treatment plus 70 days or the day before initiation of new 
anticancer therapy including SCT, whichever comes first. If the AE onset date is on or before the 
last dose date, the AE is considered as treatment-emergent AE regardless of the start of new 
anticancer therapy. 
Summaries (number and percentage of patients) of treatment-emergent AEs (by system organ 
class and preferred term) will be provided by treatment group.
8.7.3.
Laboratory Evaluations
Selected laboratory data (using conventional units) will be summarized using only observed data. 
Data and change from baseline at all scheduled time points will be summarized. Graded 
laboratory abnormalities will be defined using the grading scheme in Appendix 6.
Incidence of treatment-emergent laboratory abnormalities, 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 70 days or the day before initiation of new anticancer therapy including 
SCT, whichever comes first, will be summarized by treatment group. If baseline data are 
missing, any graded abnormality (ie, at least a Grade 1) will be considered treatment emergent.
Laboratory abnormalities that occur before the first dose of study treatment or after the patient 
has been discontinued from treatment for at least 70 days will be included in a data listing.
8.7.4.
Other Safety Evaluations
Vital signs and physical examination findings will be summarized at select time points. Details 
will be provided in the SAP.

Summaiy statistics will be presented for magrolimab sernm concentrntions at each scheduled 
time point. Descriptive graphical plots of individual sernm concentration versus time profiles and 
mean concentration versus time profiles will be generated. 
Missing concentrntion values will be reported as is in data listings. Concentration values below 
lower limit of quantitation will be handled as zero in surnmaiy statistics and repo1i ed as is in data 
listings. 
All data from this study may be combined with PK data from other company-sponsored clinical 
studies and analyzed using a population PK model. Such an analysis would be repo1ied 
separately. 
Additional analysis such as exposure-response analysis to evaluate the relationship between 
magrolimab exposure and efficacy/safety/PD biomai·kers endpoints in the study may be 
perfo1med if data allows and will be repo1i ed in a sepai·ate report when appropriate. 
8.9. 
Analysis of Patient-Reported Outcome Data 
The key PRO endpoints, TTD on the GHS/QoL scale and TTD on the physical functioning scale 
of the EORTC QLQ-C30, ai·e defined based on the ITT Analysis Set. The TTD will be 
smnmai·ized using the Kaplan-Meier method. The log-rank test stratified by randomization 
stratification factors will be conducted for the TTD compai·ison between treatment anns, and the 
HR estimated using a Cox propo1iional hazai·d regression model stratified by randomization 
stratification factors will be provided. 
Additional analysis will be conducted on PRO data, including absolute scores and changes from 
baseline for scales and single items of the EORTC QLQ-C30 instrument, the EQ-5D-5L 
instrument, and PGIS/PGIC at each assessment time point for each aim. A lineai· mixed effect 
model with treatment, time, tr·eatment by time interaction, str·atification factors, and baseline 
scores as fixed factors may be fitted for analysis of selective PRO endpoints. 
8.10. 
Immunogenicity Analysis 
Immunogenicity will be assessed using a 3-tier (screen, confnmato1y, and titer) approach on 
study sainples using a validated immunoassay. The rate and magnitude of anti-magrolimab 
antibody incidence, prevalence, persistence, and tr·ansience will be sUllllnai·ized for the 
Immune enici Anal sis Set. Titer smnmaries ma also be enerated if relevant. 
Neutr·alizing antibody analysis will be conducted using a validated assay on ADA positive

8.12. 
Sample Size 
The study will randomize approximately 432 patients in total into 2 treatment aims at a 1: 1 ratio, 
dete1mined by fo1mal hypothesis testing perfonned on the primaiy efficacy endpoint: OS, with 
family-wise Type I enor controlled at I-sided significance level of 0.025. 
It is assumed that administration of magrolimab + venetoclax + azacitidine to study patients will 
result in a median OS of approximately 21 months, improved from a median OS of 14.7 months 
in patients treated with placebo + venetoclax + azacitidine. This conesponds to an OS HR of 0. 7. 
Assuming that the dmation of OS is exponentially distributed in each of the 2 aims, with an HR 
equal to 1 under the null hypothesis of no difference between the 2 treatment anns, 303 events 
are needed to detect an HR of 0.7 with 86.4% power at a I-sided significance level of 0.025 
using a log-rank test, the first interim analysis with futility test when 40% of the infonnation 
(121 deaths) is available, and the second interim analysis with superiority test together with a 
futility test when 75% of the info1mation (227 deaths) is available, and one prima1y analysis. For 
the second OS interim analysis and the OS primaiy analysis, the Lan-DeMets alpha spending 
function with O'Brien-Fleming stopping boundaiy will be used. The futility boundai·ies for two 
interim analyses ai·e obtained using a Gamma beta-spending function with pai·ameter -5. 
With an accmal period of 19 months (with approximately 51 % of the patients emolled dming the 
initial 12 months, and the remaining 49% of the patients emolled dming the last 7 months), 
24 months of follow up, and an annual 1.43% dropout rate (5% dropout chance by 43 months 
with time to dropout assuming exponentially distributed time-to-dropout), a total sainple size of 
432 patients (216 patients per treatment group) is needed to obse1ve the required 303 events. 
8.13. 
Data Monitoring Committee 
An external multidisciplinaiy DMC will review the progress of the study, perfonn interim 
reviews of safety data at regular inte1vals, and provide recollllllendation to Gilead whether the 
nature, frequency, and severity of AEs associated with study treatment waiTant the early 
tennination of the study in the best interests of the patient, whether the study should continue as 
planned, or whether the study should continue with modifications. The DMC may also provide 
recommendations as needed regai·ding study design. 
In addition, the DMC will review the results from the interim analyses. Based on the 
pre-specified superiority and futility mles, the DMC may make recommendations to Gilead as to 
whether the study should be te1minated for futility or continue as planned. Efficacy superiority 
boundai·ies ai·e specified in Section 8.2. The nonbinding futility mle with a futility bounda1y of 
HR= 1.1 is used in the first interim analysis, and a futility boundaiy of HR= 0.9 in used in the 
second interim analysis if the null hypothesis of OS fails to be rejected at the second interim 
analysis.

The ICF will inform patients about genomic testing and/or planned sample retention. As part of 
the study-specific ICF to be signed by each patient participating in the study, patients will be 
asked to document agreement to allow the use of their samples for optional future research, in 
accordance with applicable regulations. In addition to the study-specific ICF to be signed by 
each patient participating in the study, patients will be required to document agreement to use 
already collected samples for optional genomic research. The results of the tests done on the 
samples will not be shared with the patient or the investigator.
9.1.5.
Confidentiality
The investigator must ensure that patients’ anonymity will be strictly maintained and that their 
identities are protected from unauthorized parties. Only an identification code and any other 
unique identifier(s) as allowed by local law (such as year of birth) will be recorded on any form 
or biological sample submitted to Gilead, IRB/IEC, or the laboratory. Laboratory specimens 
must be labeled in such a way as to protect patient identity while allowing the results to be 
recorded to the proper patient. Refer to specific laboratory instructions. NOTE: The investigator 
must keep a screening log with details for all patients screened and enrolled in the study, in 
accordance with the site procedures and regulations. Patient data will be processed in accordance 
with all applicable regulations.
The investigator agrees that all information received from Gilead, including but not limited to the 
IB, this protocol, CRFs/eCRFs, study drug information, and any other study information, remain 
the sole and exclusive property of Gilead during the conduct of the study and thereafter. This 
information is not to be disclosed to any third party (except employees or agents directly 
involved in the conduct of the study or as required by law) without prior written consent from 
Gilead. The investigator further agrees to take all reasonable precautions to prevent the 
disclosure by any employee or agent of the study site to any third party or otherwise into the 
public domain.
9.1.6.
Study Files and Retention of Records
The investigator must maintain adequate and accurate records to enable the conduct of the study 
to be fully documented and the study data to be subsequently verified. These documents should 
be classified into at least the following 2 categories: (1) investigator’s study file and (2) patient 
clinical source documents.
The investigator’s study file will contain the protocol/amendments, CRFs/eCRFs, IRB/IEC and 
governmental approval with correspondence, the ICF(s), drug records, staff curriculum vitae and 
authorization forms, and other appropriate documents and correspondence.
The required source data should include sequential notes containing at least the following 
information for each patient:
•
Patient identification
•
Documentation that patient meets eligibility criteria, ie, medical history, physical 
examination, and confirmation of diagnosis (to support inclusion and exclusion criteria)

All clinical study documents must be retained by the investigator for at least 2 years or according 
to local laws, whichever is longer, after the last approval of a marketing application in an ICH 
region (ie, US, Europe, or Japan) and until there are no pending or planned marketing 
applications in an ICH region; or, if no application is filed or if the application is not approved 
for such indication, for 2 years after the investigation is discontinued and regulatory authorities 
have been notified. Investigators may be required to retain documents longer if specified by 
regulatory requirements, by local regulations, or by an agreement with Gilead. The investigator 
must notify Gilead before destroying any clinical study records.
Should the investigator wish to assign the study records to another party or move them to another 
location, Gilead must be notified in advance.
If the investigator cannot provide for this archiving requirement at the study site for any or all of 
the documents, special arrangements must be made between the investigator and Gilead to store 
these records securely away from the site so that they can be returned sealed to the investigator 
in case of an inspection. When source documents are required for the continued care of the 
patient, appropriate copies should be made for storage away from the site.
9.1.7.
Case Report Forms
An electronic case report form casebook will be completed by an authorized study personnel 
member whose training for this function is completed in the electronic data capture system 
unless otherwise directed. The electronic case report form casebook will only capture the data 
required per the protocol schedule of events and procedures, unless collected by a nonelectronic 
data capture vendor system (eg, central laboratory). The Inclusion/Exclusion Criteria and 
Enrollment electronic case report forms should be completed only after all data related to 
eligibility are available. Data entry should be performed in accordance with the case report form

Completion Guidelines provided by the sponsor. Subsequent to data entry, a study monitor may 
perform source data verification. System-generated or manual queries will be issued in the 
electronic data capture system as data discrepancies are identified by the study monitor or Gilead 
personnel who routinely review the data for completeness, correctness, and consistency. The site 
investigator, site coordinator, or other designee is responsible for responding to the queries in a 
timely manner, within the system, either by confirming the data as correct or updating the 
original entry, and providing the reason for the update (eg, data entry error). Original entries as 
well as any changes to data fields will be stored in the audit trail of the system. Regular oversight 
by the principal investigator of the data entered into the electronic data capture system is 
expected to occur on an ongoing basis throughout the study to ensure quality and completeness. 
At a minimum, before any interim, final, or other timepoints (as instructed by Gilead), the 
investigator apply his/her electronic signature to confirm that the forms have been reviewed and 
that the entries accurately reflect the information in the source documents. At the conclusion of 
the study, Gilead will provide the site investigator with a read-only archive copy of the data 
entered. This archive must be stored in accordance with the records retention requirements 
outlined in Section 9.1.6.
9.1.8.

Pandemic Risk Assessment and Mitigation Plan
During an ongoing pandemic, potential risks associated with patients being unable to attend 
study visits have been identified for this study. Special pandemic measures can be applied only 
when in accordance with the current situation and applicable local authority regulations, 
recommendations, or similar. These potential risks and mitigation plans can be summarized as 
follows:
1) Schedule of assessments:
a) Physical examination:
i)
For all assessments where a physical examination is indicated, this portion of the visit 
can be conducted virtually; however, when samples need to be collected or dosing 
performed, these activities must occur in the clinic.
ii) If a virtual visit is conducted for the physical examination assessment portion, in 
order to limit a patient’s time in the clinic, vital signs may be omitted.
b) Dosing:
i)
Dosing delays with magrolimab/placebo:
(1) For patients who may have travel restrictions, the 4-week period of 
magrolimab/placebo dose delay for repriming can be extended to 6 weeks in order 
to minimize the need for repriming for patients in this scenario. Medical monitor 
approval is needed for this specific situation.
ii) Dosing with azacitidine:
(1) If needed under specific circumstances, sites can allow for administration of 
azacitidine locally nearer to patient’s residence, with proper documentation (eg, 
name of site, name of physician overseeing transfusion, name of laboratory used, 
including accreditation certificate). Administration of azacitidine outside the 
center should be reserved only in cases where patients will not be able to get 
azacitidine dosing otherwise.
(2) If treatment administration is given locally, then the patient should be evaluated 
by a local hematologist on Day 1 of that treatment cycle and have all laboratory 
assessments required on the Day 1 treatment cycle performed as per the protocol. 
The site should procure the clinical notes and laboratory reports for the principal 
investigator review and signature. The site is to ensure that all of these documents 
are filed in the patient’s source records.
(3) The treating physician at the study site should speak to the local hematologist and 
review protocol guidelines/dosing of azacitidine/reporting of reactions and 
document this information in the medical records.

Page 126
15 December 2023
iii) Venetoclax supply to patients:
(1) Patients may be unable to return to the site for a number of visits to get 
venetoclax, or the site may be unable to accept any patient visits.
Mitigation plan: Venetoclax may be provided to the patient from the site without 
a clinic visit, once it is confirmed that the patient may safely continue on 
venetoclax as determined by the principal investigator. A virtual study visit, via 
phone or video conferencing, must be performed prior to remote study drug 
resupply. At the earliest opportunity, the site will schedule in-person patient visits 
and return to the protocol’s regular schedule of assessments. A qualified courier 
may be utilized to ship venetoclax from sites to study patients if permitted by 
local ethic committee (EC)/institutional review boards (IRB)/Regulatory 
Authority as applicable and with sponsor’s approval.
c) Sample collection:
i)
While it is preferred to collect all protocol-specified laboratory samples, if resources 
are limited, PK/ADA samples may be collected and stored (frozen) and not shipped in 
real time if staff are not available to do so.
ii) For correlative peripheral blood or bone marrow aspirate samples, if they cannot be 
shipped according to their corresponding standard procedures same day, or 
refrigerated overnight for shipment the next day, please isolate the mononuclear cells 
(eg, by Ficoll gradient) and cryopreserve according to local best practices. If it is not 
possible to either ship samples or preserve and store according to the guidance above, 
then collection of these samples may be omitted until normal operations can resume.
d) General patient selection guidance:
i)
To minimize patients receiving RBC transfusions given the current transfusion 
product shortage, we recommend selecting patients with higher hemoglobin 
thresholds at baseline and use IV iron and/or erythropoietin where clinically 
indicated.
2) Study drug supplies to sites:
a) Shipments of study drug could be delayed because of transportation issues. Without study 
drug patients would not be able to stay on the study drug as planned per protocol.
Mitigation plan: The sites’ study drug inventory should be closely monitored. Site staff 
should notify the sponsor or delegate if there is any interruption in local shipping service. 
The sponsor will continue to monitor inventory at the study drug depot and study sites. 
Manual shipments will be triggered as necessary.

3) Patient safety monitoring and follow-up:
a) Patients may be unable or unwilling to come to the study site for their scheduled study 
visits as required per protocol.
Mitigation plan: For patients who may be unable or unwilling to visit the study site for 
their scheduled study visits as required per protocol, the principal investigator or 
qualified delegate will conduct a virtual study visit, via phone or video conferencing, to 
assess the patient within target visit window date whenever possible. During the virtual 
study visit, the following information at minimum will be reviewed:
i)
Confirm if patient has experienced any adverse events (AEs)/serious adverse events 
(SAEs)/special situations (including pregnancy) and follow-up on any unresolved 
AE/SAEs.
ii) Review current list of concomitant medications and document any new concomitant 
medications.
iii) If applicable, confirm patient’s study drug supply is sufficient to last until the next 
planned visit date. If study drug resupply is needed it will be provided as described 
above in (2).
iv) If applicable, remind patient to maintain current dosing and to keep all dispensed 
study drug kits for return at the next on-site visit.
b) Patients may be unable or unwilling to travel to the site for planned assessments (eg, 
safety blood draws);
Mitigation plan: Local laboratories may be utilized as appropriate to monitor patient 
safety until the patient can return to the site for their regular follow-up per protocol. Any 
laboratory assessments conducted at a local laboratory due to the pandemic will be 
documented accordingly. Pregnancy testing may be performed using a home urine 
pregnancy test if local laboratory pregnancy testing is not feasible.
c) Patients may be unable or unwilling to attend the study visit to sign an updated informed 
consent form (ICF) version.
Mitigation plan: The site staff will follow their approved consent process and remain in 
compliance with local EC/IRB and national laws and regulations. Remote consent will be 
allowed if has been approved by the local EC/IRB. The consent process will be 
documented and confirmed by normal consent procedure at the earliest opportunity.
d) The safety of trial participants is important and testing of coronavirus disease 2019 
(COVID-19) infection will be based on local clinical guidelines for testing based on 
signs/symptoms and or suspected exposure to COVID-19.

Mitigation plan: If a patient has a diagnosis of COVID-19 while on this clinical study, 
study drugs may be held until clinical improvement or resolution in accordance with the 
treating physician’s judgment and general magrolimab/azacitidine/venetoclax dose delay 
guidance in the protocol. Additional supportive care and treatment measures for 
COVID-19 infection on the study will be performed in accordance with local institutional 
guidelines. Patients with a COVID-19 infection while participating in a clinical trial will 
have this event documented as an adverse event in the clinical database.
4) Protocol and monitoring compliance:
a) Protocol deviations may occur, in case scheduled visits cannot occur as planned per 
protocol.
Mitigation plan: If it is not possible to complete a required procedure, an unscheduled 
visit should be conducted as soon as possible when conditions allow. The situation should 
be recorded and explained as a protocol deviation. Any missed patient visits or deviation 
to the protocol due to the pandemic must be reported in the eCRF and described in the 
clinical study report. Any virtual study visits that are conducted in lieu of clinic visits due 
to the pandemic will be documented as a protocol deviation related to the pandemic.
b) Monitors may be unable to carry out source data review or source data verification 
(SDV), or study drug accountability or assess protocol and GCP compliance. This may 
lead to delays in SDV, an increase in protocol deviations, or under reporting of AEs.
Mitigation plan: The study monitor is to remain in close communication with the site to 
ensure data entry and query resolution. In compliance with Gilead policy, a remote SDV 
should not be arranged. The study monitor is to reference the Study Monitoring Plan for 
guidance on how to conduct a remote monitoring visit. The study staff is to save and 
document all relevant communication in the study files. The status of sites that cannot 
accept monitoring visits and/or patients on site must be tracked centrally and updated on 
a regular basis.
5) Missing data and data integrity:
a) There may be an increased amount of missing data due to patients missing 
visits/assessments. This could have an impact on the analysis and the interpretation of 
clinical trial data.
Mitigation plan: Implications of a pandemic on methodological aspects for the study will 
be thoroughly assessed and documented, and relevant actions will be taken as appropriate 
(ie, modification of the statistical analysis plan) and in compliance with regulatory 
authorities’ guidance. Overall, the clinical study report will describe the impact of the 
pandemic on the interpretability of study data.

Risks will be assessed continuously, and temporary measures will be implemented to mitigate 
these risks as part of a mitigation plan, as described above. These measures will be 
communicated to the relevant stakeholders as appropriate and are intended to provide alternate 
methods that will ensure the evaluation and assessment of the safety of patients who are enrolled 
in this study.
Since these potential risks are considered mitigated with the implementation of these measures, 
the expected benefit-risk assessment of magrolimab in study patients remains unchanged. In the 
event that these potential risks cannot be mitigated due to the escalation of a pandemic, 
randomization of new patients will be placed on hold until the pandemic outbreak is under 
control by following local regulatory guidelines.

a
Any other visit window specifications for individual assessments should be applied.
b
If the patient is cytopenic at Day 28, CBC is to be monitored at least twice per week for 2 weeks or until optimal count recovery is reached (whichever comes first). The best 
CBC result within the ± 2-week window is to be used for the response assessment, with the date of response being the date of the bone marrow assessment. Complete blood 
count need not be repeated if the prior CBC (including prior Day 28 CBC) is within 3 days of Day 1.
c
Screening must be completed prior to randomization. Randomization must occur within 30 days of signing informed consent. The first dose of study treatment must be given 
within 72 hours after randomization.
d
Complete physical examination is to be performed at screening and symptom-directed physical examination is to be performed from Cycle 1 Day 1.
e
Pretreatment assessments for the initial dose (Cycle 1 Day 1) may be collected up to 72 hours before administration of any study treatment; thereafter, pretreatment 
assessments are to be collected within 24 hours prior to any study treatment administration. 
f
Vital signs will be assessed prior to administration of any study treatment. Details are provided in Section 6.6.4. Height will be collected at screening only. Weight will be 
collected at screening and Day 1 of each cycle.
g
A serum pregnancy test will be conducted at screening and serum or urine pregnancy tests will be conducted every 4 weeks thereafter and can be performed locally without a 
requirement to visit the study site. A follicle-stimulating hormone test is required for female patients who are < 54 years old who are not on hormonal contraception and who 
have stopped menstruating for ≥ 12 months but do not have documentation of ovarian hormonal failure. The Cycle 1 Day 1 pregnancy test does not need to be repeated if the 
screening pregnancy test was performed within the 72 hours before study treatment administration. Additional guidance is provided in Section 6.6.1.
h
Additional samples for CBC may be collected outside of the protocol-specified time points to ensure a WBC level ≤ 20 × 103/µL prior to each magrolimab/placebo dose 
during Cycle 1.
i
To monitor the risk of tumor lysis syndrome during venetoclax ramp-up, blood chemistry is to be collected predose and 6 to 8 hours postdose of venetoclax administration on 
Cycle 1 Day 1, Cycle 1 Day 2, and Cycle 1 Day 3. An additional blood chemistry is to be collected 24 hours (±3 hours) after the Cycle 1 Day 3 administration.
j
ABO/Rh type, antibody screen, DAT, and extended RBC phenotyping (including minor antigens such as CcDEe, Cw, MNSs, Kk, FyaFyb, and JkaJkb) must be performed for 
each participant. Red blood cell genotyping instead of extended RBC phenotyping is acceptable for any patient. Red blood cell genotyping (instead of an extended RBC 
phenotyping) must be performed if a participant received any RBC or whole blood transfusion within the previous 3 months (unless the laboratory has availability for special 
techniques for performing phenotyping for participants with a recent transfusion). Results must be available before the first dose of magrolimab.

m
All SAEs and any AEs related to protocol-mandated procedures should be collected at screening. Adverse events should be recorded at all scheduled and unscheduled 
assessment visits, and at all treatment visits, even when other assessments are not scheduled.
n
Prior and concomitant medications should be collected at screening. Concomitant medications should be recorded at all scheduled and unscheduled assessment visits, and at 
all treatment visits, even when other assessments are not scheduled.
o
Four PRO instruments will be administered in this study: the EORTC QLQ-C30 questionnaire, the EQ-5D-5L, the PGIS, and the PGIC. The patient should complete these 
questionnaires before any other study procedures at required visits. EORTC QLQ-C30 and EQ-5D-5L questionnaires should be performed prior to PGIS/PGIC. PGIC is not 
required at Cycle 1 Day 1. If the PRO instruments are not available in a patient’s language, patients are not required to complete the assessments. Patients with other situations 
related to PRO instrument completion (eg, visual impairment/blindness, limitation in upper extremity mobility/dexterity) may be exempt from these assessments after 
discussion with the sponsor.
p
Peripheral blood smears for blasts are to be collected along with bone marrow aspirate/biopsy.
q
Samples will be collected predose within 12 hours prior to study treatment administration.
r
Starting at Cycle 2 Day 1, peripheral blood samples for biomarker studies on Cycle X Day 1 do not need to be repeated at Day 1 of the cycle if they have been collected 
within the past 7 days.
s
A trephine (biopsy) is to be collected if the aspirate sample is dry (not obtainable). If a bone marrow aspirate sample is not evaluable, another aspirate sample must be performed 
within 7 days. At screening, this procedure must be performed prior to the first dose of study treatment at the latest. An aspirate sample will be collected for response assessment 
(eg, blast evaluation), cytogenetics, MRD assessment (performed during the first 6 cycles only), biomarker studies, and biobanking. When done on the same day, bone marrow 
aspirate samples are to be obtained at the time of bone marrow (trephine) biopsy. Conventional cytogenetics are to be tested per institutional standards.

Disease Response Criteria Based on European LeukemiaNet (ELN) 
and International Working Group (IWG) Criteria
Assessment of leukemia response in AML patients will be conducted using the European 
LeukemiaNet (ELN) 2017 recommendations for AML with modifications {Dohner 2017} 
(Appendix Table 6). Response classifications include complete remission without minimal 
residual disease (CRMRD-), complete remission with positive or unknown minimal residual 
disease (CRMRD+/unk), CR with incomplete hematologic recovery (CRi), morphologic leukemia-
free state (MLFS), partial remission (PR), and stable disease (SD).
In addition, CR with partial hematologic recovery (CRh) will be assessed for AML, as defined as 
patients who achieve a CR per AML ELN 2017 recommendations {Dohner 2017}, but with only 
partial recovery of peripheral blood counts (platelets > 50  109/L and absolute neutrophil count 
(ANC) > 0.5  109/L).
Cytogenetic CR (cCR) will be assessed by 2003 IWG criteria as CR with normal cytogenetics 
(Appendix Table 7) {Cheson 2003}.
Hematologic improvement will be assessed by 2006 IWG criteria {Cheson 2006} to compare 
with disease response assessed by 2017 ELN criteria (Appendix Table 8) {Dohner 2017}.
The date of the bone marrow assessment should be used as the date of response assessment. 
Complete blood count results used for the response assessment will be derived from the best 
accompanying laboratory CBC result within the ± 2-week window of the bone marrow 
assessment used to support the efficacy response assessment. All components (eg, platelets, 
absolute neutrophils) should come from the same test. If disease progression or relapse is 
assessed based on CBC assessments or new extramedullary disease or both, other than bone 
marrow blast assessments, then the date of the corresponding CBC or new extramedullary 
disease assessment or the earlier of these 2 dates will be used as the date of response assessment.

Appendix 5.
Pregnancy Precautions, Definition for Female of Childbearing 
Potential, and Contraceptive Requirements
1) Definitions
a. Definition of Childbearing Potential
Magrolimab is contraindicated in pregnancy as a higher incidence of total pregnancy loss has 
been observed in an embryo-fetal development toxicity study in cynomolgus monkeys and there 
is a strong suspicion of human fetotoxicity in early pregnancy based on the nonclinical data. For 
magrolimab, there is no anticipated PK interaction with progestin or other steroids based on the 
distinct clearance pathways. 
For the purposes of this study, a female-born patient is considered of childbearing potential 
following the initiation of puberty (Tanner stage 2) until becoming postmenopausal unless the 
patient is permanently sterile or has medically documented ovarian failure.
Women are considered to be in a postmenopausal state when they are ≥ 54 years of age with 
cessation of previously occurring menses for ≥ 12 months without an alternative cause. In 
addition, women < 54 years of age with amenorrhea of ≥ 12 months may also be considered 
postmenopausal if their follicle-stimulating hormone (FSH) level is in the postmenopausal range 
and they are not using hormonal contraception or hormonal replacement therapy.
Permanent sterilization includes hysterectomy, bilateral oophorectomy, or bilateral 
salpingectomy in a female patient of any age.
b. Definition of Male Fertility
For the purposes of this study, a male born patient is considered fertile after the initiation of 
puberty unless the patient is permanently sterile by bilateral orchidectomy or medical 
documentation.
2) Contraception Requirements for Female Patients
a. Study Drug Effects on Pregnancy and Hormonal Contraception
There are no adequate and well-controlled studies of magrolimab in pregnant women. 
Magrolimab when dosed to pregnant monkeys was not teratogenic, but resulted in stillbirth and 
neonate deaths, secondary to fetal anemia. Based on these data, magrolimab should not 
administered to pregnant women. Advise females with reproductive potential to avoid pregnancy 
during treatment with magrolimab and for at least 3 months after treatment.
For magrolimab, there is no anticipated PK interaction with progestin or other steroids based on 
the distinct clearance pathways.

15 December 2023
Based on the mechanism of action (MOA) and findings in animals, azacitidine may cause fetal 
harm when administered to a pregnant woman. Advise females with reproductive potential to 
avoid pregnancy during treatment with azacitidine. Studies in vitro have demonstrated that CYP 
enzyme induction or inhibition by azacitidine at clinically achievable plasma concentrations is 
unlikely.
Based on its MOA and findings in animals, venetoclax may cause embryo-fetal harm when 
administered to a pregnant woman. Advise females with reproductive potential to avoid 
pregnancy during treatment with venetoclax. It is currently unknown whether venetoclax may 
reduce the effectiveness of hormonal contraceptives.
Refer to the latest version of the magrolimab IB for additional information. Refer to the regional 
prescribing information for additional information on the potential risks of treatment with 
azacitidine, and venetoclax.
b. Contraception Requirements for Female Patients of Childbearing Potential
The inclusion of female patients of childbearing potential requires the use of highly effective 
contraceptive measures with a failure rate of < 1% per year. They must have a negative serum 
pregnancy test at screening and a negative pregnancy test is required prior to study treatment 
administration on Cycle 1 Day 1. Pregnancy tests will be performed every 4 weeks thereafter 
until the end of contraception requirement. Duration of required contraception for female 
patients in this clinical trial should start from screening visit until 6 months after the last dose of 
study drug administered. Female patients must agree to one of the following contraceptive 
methods:
Complete abstinence from intercourse of reproductive potential. Abstinence is an acceptable 
method of contraception only when it is in line with the patient’s preferred and usual lifestyle.
Or
Consistent and correct use of 1 of the following methods of birth control listed below:
•
Non-hormonal intrauterine device (IUD)
•
Hormonal IUD (must be used in conjunction with a barrier method)
•
Bilateral tubal occlusion (upon medical assessment of surgical success)
•
Vasectomy in the male partner (upon medical assessment of surgical success)
Or 
Female patients who wish to use a hormonally based method must use it in conjunction with a 
barrier method, preferably a male condom. Hormonal methods are restricted to those associated 
with the inhibition of ovulation. Hormonally based contraceptives and barrier methods permitted 
for use in this protocol are as follows:

•
Hormonal methods (each method must be used with a barrier method, preferably male 
condom)
Oral contraceptives (either combined or progesterone only)
Injectable progesterone
Transdermal contraceptive patch
Contraceptive vaginal ring
Subdermal contraceptive implant
•
Barrier methods (each method must be used with a hormonal method)
Male condom (with or without spermicide)
Female condom (with or without spermicide)
Diaphragm with spermicide
Cervical cap with spermicide
Sponge with spermicide
Inclusion of methods of contraception in this list of permitted methods does not imply that the 
method is approved in any country or region. Methods should only be used if locally approved.
Female patients must also refrain from egg donation, cryopreservation of cells, and in vitro 
fertilization during treatment and until the end of contraception requirement. If needed, female 
patients should be advised to seek advice about egg donation and cryopreservation prior to 
treatment.
3) Contraception Requirements for Male Patients
Male patients with female partners of childbearing potential must use condoms during treatment 
and until 3 months (6 months in Canada only) after the last dose of study drug administered. If 
the female partner of childbearing potential is not pregnant, use of any locally approved 
contraceptive method should also be considered.
Male patients must also refrain from sperm donation and cryopreservation of cells during 
treatment and until the end of contraception requirement. If needed, male patients should be 
advised to seek advice about sperm donation and cryopreservation prior to treatment.

4) Unacceptable Birth Control Methods
Birth control methods that are unacceptable include periodic abstinence (eg, calendar, ovulation, 
symptothermal, postovulation methods), withdrawal (coitus interruptus), spermicides only, and 
lactational amenorrhea method. A female condom and a male condom should not be used 
together.
5) Procedures to Be Followed in the Event of Pregnancy
Female patients will be instructed to notify the investigator if they become pregnant or suspect 
they are pregnant at any time from start of the study to 6 months post last study drug dose. Study 
drug must be discontinued immediately.
Male patients whose partner has become pregnant or suspects she is pregnant from start of study 
to 3 months post last study drug dose must also report the information to the investigator.
Instructions for reporting pregnancy and pregnancy outcome are outlined in Section 7.4.2.3.

Prognostic impact of a marker is treatment-dependent and may change with new therapies.
b
Low, low allelic ratio (< 0.5); high, high allelic ratio (≥ 0.5); semiquantitative assessment of FLT3-ITD allelic ratio (using 
DNA fragment analysis) is determined as ratio of the area under the curve “FLT3-ITD” divided by area under the curve 
“FLT3-wild-type”; recent studies indicate that AML with NPM1 mutation and FLT3-ITD low allelic ratio may have a more 
favorable prognosis and patients should not routinely be assigned to allogeneic HCT. 
c
The presence of t(9;11)(p21.3;q23.3) takes precedence over rare, concurrent adverse-risk gene mutations.
d
Three or more unrelated chromosome abnormalities in the absence of 1 of the WHO-designated recurring translocations or 
inversions, that is, t(8;21), inv(16) or t(16;16), t(9;11), t(v;11)(v;q23.3), t(6;9), inv(3) or t(3;3); AML with BCR-ABL1.
e
Defined by the presence of 1 single monosomy (excluding loss of X or Y) in association with at least 1 additional 
monosomy or structural chromosome abnormality (excluding core-binding factor AML).
f
These markers should not be used as an adverse prognostic marker if they co-occur with favorable-risk AML subtypes.
g
TP53 mutations are significantly associated with AML with complex and monosomal karyotype.
Frequencies, response rates, and outcome measures should be reported by risk category, and, if sufficient numbers are available, 
by specific genetic lesions indicated.

Peripheral blood, bone man·ow aspirate, and trephine biopsy samples will be collected from all 
patients who have provided consent to participate in this study. Bone marTow trephine biopsy 
for biomarker studies ar·e optional. However, for patients whose bone man·ow aspirate is dry 
(not obtainable), trephine biopsy samples will be required for biomarker studies. On-treatment 
Bromar er samp es may e use to eva uate t e association of 
systermc an or tissue- ase 
iomarkers with study drug response, including efficacy and/or 
AEs, dose optimization, and to better understand the biology of AML in general. Because 
biomar·ker science is a rapidly evolving area of investigation, and AEs in particular· are 
difficult to predict, it may not be possible to specify prospectively all tests that may be done on 
the specimens provided. The specific analyses will include, but may not be limited to, the 
biomar·kers and assays described below. The testing outlined below is based upon the cun-ent 
state of scientific knowledge. It may be modified during or after the end of the study to 
remove tests no longer indicated and/or to add new tests based upon new state of the art 
knowledge.

If the patient is cytopenic at Day 28, CBC is to be monitored at least twice per week for 2 weeks or until optimal count recovery is reached (whichever comes first). The best 
CBC result within the ± 2-week window is to be used for the response assessment, with the date of response being the date of the bone marrow assessment. Complete blood 
count need not be repeated if the prior CBC (including prior Day 28 CBC) is within 3 days of Day 1.

Amendment 7 
c 
Screening must be completed prior to randomization. Randomization must occtu· within 30 days of signing info,med consent. The first dose of study treatment must be given 
within 72 hotu·s after randomization. 
d 
Complete physical examination is to be pe1fo1med at screening and symptom-directed physical examination is to be pe,fonued from Cycle 1 Day 1. 
e 
Pretreatment assessments for the initial dose (Cycle 1 Day 1) may be collected up to 72 hotu-s before administration of any study treatment; thereafter, pretreatment 
assessments are to be collected within 24 hours prior to any study treatment administration. 
f 
Vital signs will be assessed prior to administration of any study treatment. Details are provided in Section 6.6.4. Height will be collected at screening only. Weight will be 
collected at screening and Day 1 of each cycle. 
g 
A senuu pregnancy test will be conducted at screening and senuu or tu-ine pregnancy tests will be conducted eve,y 4 weeks thereafter and can be pe1fo1med locally without a 
requirement to visit the study site. A follicle-stimulating hormone test is required for female patients who are < 54 years old who are not on ho,monal contraception and who 
have stopped menstruating for:;:: 12 months but do not have doctuuentation of ovarian honuonal failure. The Cycle 1 Day 1 pregnancy test does not need to be repeated if the 
screening pregnancy test was pe1fo1med within the 72 hotu·s before study treatment administration. Additional guidance is provided in Section 6.6.1. 
h 
Additional samples for CBC may be collected outside of the protocol-specified time points to enstu·e a WBC level~ 20 x 103/µL prior to each magrolimab/placebo dose 
dtu-ing Cycle 1. 
To monitor the risk of ttuuor lysis syndrome dtu-ing venetoclax ramp-up, blood cheinistry is to be collected predose and 6 to 8 hours postdose of venetoclax administration on 
Cycle 1 Day 1, Cycle 1 Day 2, and Cycle 1 Day 3. An additional blood cheinistry is to be collected 24 hours (±3 hours) after the Cycle 1 Day 3 administration. 
ABO/Rh type, antibody screen, DAT, and extended RBC phenotyping (including minor antigens such as CcDEe, Cw, MNSs, Kk, FyaFyb, and JkaJkb) must be performed for 
each participant. Red blood cell genotyping instead of extended RBC phenotyping is acceptable for any patient. Red blood cell genotyping (instead of an extended RBC 
phenotyping) must be performed if a pa,ticipant received any RBC or whole blood transfusion with.in the previous 3 months (unless the laboratory has availability for special 
techniques for pe1fo1ming phenotyping for participants with a recent transfusion). Results must be available before the first dose of magrolimab. 
k 
Only for patients:;:: 18 to 74 years of age with cardiac disease, if needed to detennine ineligibility to intensive chemotherapy

Only for patients:;:: 18 to 74 years of age with pulmonary disease, if needed to detennine ineligibility to intensive chemotherapy 
m 
All SAEs and any AEs related to protocol-mandated procedtu·es should be collected at screening. Adverse events should be recorded at all scheduled and unscheduled 
assessment visits, and at all treatment visits, even when other assessments are not scheduled. 
n 
P,-ior and concoinitant medications should be collected at screening. Concoinitant medications should be recorded at all scheduled and unscheduled assessment visits, and at 
all treatment visits, even when other assessments are not scheduled. 
o 
Fotu· PRO instnuuents will be administered in this study: the EORTC QLQ-C30 questionnaire, the EQ-SD-SL, the PGIS, and the PGIC. The patient should complete these 
questionnaires before any other study procedures at required visits. EORTC QLQ-C30 and EQ-SD-SL questionnaires should be performed p1-ior to PGIS/PGIC. PGIC is not 
required at Cycle 1 Day 1. If the PRO instnuuents are not available in a patient's language, patients are not required to complete the assessments. Patients with other sitt1ations 
related to PRO instrtuuent completion (eg, visual impaiiment/blindness, liiuitation in upper extreinity mobility/dexte1-ity) may be exempt from these assessments after 
discussion with the sponsor. 
p 
Pe1-ipheral blood smears for blasts are to be collected along with bone mrul'Ow aspirate. 
q 
Samples w-ill be collected predose within 12 hours p1-ior to study treatment administration. 
r 
Sta,ting at Cycle 2 Day 1, peripheral blood samples for biomarker studies on Cycle X Day 1 do not need to be repeated at Day 1 of the cycle if they have been collected 
within the past 7 days. 
s 
If a bone mru1·ow aspii-ate sruuple is not evaluable, another aspii-ate sruuple must be peiformed within 7 days. At screening, th.is procedtu-e must be perfonued p1-ior to the fo-st dose 
of stt1dy treatment at the latest. An aspii-ate sruuple will be collected for 1-esponse assessment ( eg, blast evaluation), cytogenetics, MRD assessment (peiformed durin . the first 6
