Protocol Amendment Summary of Changes Table 
 
Amendment 6 (02 February 2021) 
Overall Rationale for the Amendment: Amendment 6 was necessary to enable (1) any 
participant in the NINT cohort who (in the investigator’s clinical judgement) continues to 
derive clinical benefit may access study medication(s), and (2) participants previously 
enrolled in B1371012 who (in the investigator’s clinical judgement) continue to derive 
clinical benefit can enroll in this study purely for continued access to study medication(s). 
 
The protocol amendment summary of changes table for past amendment(s) is provided in 
Appendix 13.

Summary and Rationale for Changes 
Amendment 6 
02 February 2021 
This amendment has extensive changes 
throughout. An overview of the changes is as 
follows: 
(1) The title of the protocol has been updated to 
indicate only participants in the NINT cohort are 
continuing in the study starting with this 
amendment and moving forward that the study is 
unblinded and not placebo controlled, and 
participants with MDS or CMML may be 
included. 
(2) Efficacy assessments are no longer applicable 
in this Amendment (Section 3 and Section 8.1). 
(3) Statistical hypothesis and analysis applicable in 
previous amendments are no longer applicable in 
this Amendment. The only reporting is safety 
analyses (Section 3, Section 8.2, and Section 9). 
(4) The SOA found in Section 1.3 is replacing the 
previous SOA and has been revised to decrease the 
frequency of study procedures while maintaining 
appropriate assessment of patient safety. 
(5) INT cohort Population: Given the EDMC 
futility conclusion, standard of care therapy will be 
maintained until the end of the Consolidation 
phase. Experimental therapy will end in the post 
consolidation phase. 
(6) Restricted concomitant medications have been 
updated to further align with the information in the 
Investigator’s Brochure.

Summary and Rationale for Changes 
In addition, the following Letters to Investigators 
that were issued since the release of Amendment 5 
are addressed as follows: 
Letter dated 12 Jun 2019: 
• The content of this letter was to clarify 
discrepancies between all versions of the 
protocol up to and including Amendment 5, 
and the Japanese translated version of the 
protocol. The Japanese-translated protocols 
had additional supportive instructions 
which did not appear in the English 
version. 
• The content of the letter is no longer 
applicable to this Amendment so is not 
incorporated in this amendment. The letter 
is attached to Appendix 13. 
Letter dated 1 Aug 2019: 
• The contraception language for male 
participants (which includes condom use) 
is included in Section 10.4.1. 
• The definition of postmenopausal women 
in Section 5.3.2 has been revised to not 
include “age 60 or older”. 
• The change in one of the items in footnote 
for the SOA is no longer applicable in this 
protocol. 
Letter dated 09 Apr 2020: 
• New data capturing scenarios was 
communicated as a result of COVID-19. 
The data capture communicated in the 
letter was in effect in the trial conduct as of 
the date of the letter until the last 
participant completed amendment 5 of the 
protocol. The letter is incorporated in 
Appendix 13. 
• For this Amendment (Amendment 6) 
COVID-related measures are described in 
Appendix 7.

1. PROTOCOL SUMMARY 
1.1. Synopsis 
Short Title: Continuation Study Evaluating Azacitidine With or Without Glasdegib 
(PF-04449913) In Patients With Previously Untreated AML, MDS, or CMML. 
 
Rationale 
The B1371012 Parent Study (Amendment 7, 14 June 2018) is closing; however, participants 
in the MDS expansion cohort continue to demonstrate clinical benefit per their treating 
investigator, therefore are allowed to continue study intervention under Study B1371019 
Protocol Amendment 6. 
 
The B1371019 Protocol (Amendment 5, 12 April 2019) contained 2 cohorts: INT and NINT. 
The EDMC concluded that glasdegib offered no survival benefit in either the INT or NINT 
cohorts. There were no unexpected safety findings. 
 
As Per Protocol B1371019 Amendment 5, Section 9, methodology for summary and 
statistical analyses are detailed in the SAP. Per the SAP, the goals of the interim analyses are 
to allow early stopping of the study for futility or efficacy. The EDMC reviewed data before 
the study was unblinded to investigators. Following the EDMC conclusion of futility for both 
cohorts, investigators and participants on the B1371019 study were unblinded to study 
treatment prior to starting Amendment 6 and no further study therapy would be given in the 
INT cohort once consolidation therapy completes. No further follow-up is required past the 
mandatory 28 days safety follow-up period. . 
 
The purpose of Amendment 6 is to provide continued access to study intervention 
(azacitidine with or without glasdegib), and collection of safety data for eligible participants 
who continue to derive a clinical benefit from study treatment in studies B1371019 and 
B1371012. 
 
1.1.1. INT Cohort Population (Investigator Instructions Communicated for Both 
Cohorts Following Amendment 5 Study Design) 
Study participants - consolidation phase: 
• Study participants must be contacted to review treatment therapy. 
• May continue to receive consolidation treatment on study (with or without glasdegib) 
if in the investigator’s clinical judgement the participant is deriving clinical benefit. 
• Participants receiving consolidation treatment on the study (with or without 
glasdegib), must be re-consented by signing the IRB/EC approved consent addendum. 
• Participants who continue study intervention must follow the protocol and have all 
procedures and assessments done. Once treatment ends, study participants will be 
followed for 28 days after last dose or until the date consent is withdrawn, then no 
further follow-up will be required. 

Glasdegib PF-04449913 
Protocol B1371019 
Final Protocol Amendment 6, 02 February 2021 
PFIZER CONFIDENTIAL 
Page 11 
 
 
• Once consolidation therapy ends, no further treatment will be given. Following that 
time, no further follow-up is required outside the 28 day safety reporting period (if 
consent is not withdrawn). 
 
• Study participants – post consolidation phase: 
• Participants must end study treatment as soon as possible. 
• Participants must sign the IRB/EC approved consent addendum noting that post 
consolidation treatment will end. 
• Once post-consolidation therapy ends, no further treatment will be given. Participants 
will be followed for 28 days after last dose or until the date consent is withdrawn. 
Following that time, no further follow-up is required. 
 
• Study participants -in follow-up (past 28 day safety reporting period): 
• Participants in either cohort (INT or NINT) must end follow-up procedures in the 
study as soon as possible. 
 
Objectives and Endpoints 
 
Objective 
Endpoint 
• 
To monitor the safety and tolerability of the 
investigational drugs in participants continuing 
study intervention from this study and 
participants originating from Study B1371012. 
• 
All AEs and SAEs 
 
Overall Design 
Study design is as described in the B1371019 Protocol (Amendment 5, 12 April 2019) and 
Study B1371012 Protocol (Amendment 7, 14 June 2018). This is an open-label, continuation 
protocol for eligible NINT cohort participants enrolled in Study B1371019 or Study 
B1371012 eligible participants. 
 
Number of Participants 
A maximum of 34 participants from Study B1371019 and 3 participants originating from 
Study B1371012 who continue to derive clinical benefit per the treating investigators will be 
allowed continued access to the study intervention per Amendment 6. 
 
Note: "Enrolled" means a participant's, or his or her legally authorized representative’s, 
agreement to participate in a clinical study following completion of the informed consent 
process. Potential participants who are screened for the purpose of determining eligibility for 
the study, but do not participate in the study, are not considered enrolled, unless otherwise 
specified by the protocol.

Intervention Groups and Duration 
• Azacitidine will be administered 75 mg/m2/day for 7 days every 28 days as per local label 
or per the IP Manual (or SPC). Azacitidine may be administered by SC injection or IV 
infusion. Alternate dosing schedules to administer the 7 doses to accommodate 
participant and treatment center availability are allowed. The starting dose regimen will 
be the same as the most recent regimen received on the B1371019 or B1371012 study. 
 
• Glasdegib will be orally administered daily (50, 75 or 100 mg) and continuously. The 
starting dose regimen will be the same as the most recent regimen received on the 
B1371019 or B1371012 study. 
 
• Study intervention should be continued until objective disease progression or relapse, 
death, unacceptable toxicity, or participant refusal, whichever occurs first. 
 
Data Monitoring Committee or Other Independent Oversight Committee: None as the 
EDMC has been retired after study futility conclusions prior to Amendment 6. 
 
Statistical Methods 
Detailed methodology for summary and statistical analyses of the safety data collected in this 
continuation study is outlined in Section 9. 
 
The safety analyses of participants from Study B1371019 and participants originating from 
Parent Study B1371012 will be conducted separately and independently of each other.

2. INTRODUCTION 
Protocol Amendment 6 is applicable to all eligible participants from Study B1371019 and 
participants originating from Study B1371012 continuing on study intervention with 
azacitidine with or without glasdegib. 
Please refer to Protocol Amendment 5, 12 April 2019, for the full protocol design. Glasdegib 
(PF-04449913) is a novel small molecule inhibitor of the Sonic Hh pathway approved in the 
US by the FDA in 2018 to be used in combination with LDAC for the treatment of newly- 
diagnosed AML in adults who are 75 years of age or older or who have comorbidities that 
may preclude the use of intensive chemotherapy. Glasdegib is being developed for the 
treatment of hematologic malignancies. 
Azacitidine (VIDAZA®) is a chemical analogue of the cytosine nucleoside whose mechanism 
of action involves inhibition of DNA methyltransferase at low doses, causing 
hypomethylation of DNA, and direct cytotoxicity in abnormal hematopoietic cells in the 
bone marrow through its incorporation into DNA and RNA at high doses, resulting in cell 
death. Use of azacitidine has been approved by the FDA and EMA. 
 
2.1. Study Rationale 
The B1371012 Parent Study (Amendment 7, 14 June 2018) is closing; however, participants 
in the MDS expansion cohort continue to demonstrate clinical benefit per their treating 
investigator, therefore are allowed to continue study intervention under Study B1371019 
Protocol Amendment 6. 
 
The B1371019 Protocol (Amendment 5, 12 April 2019) contained 2 cohorts: INT and NINT. 
The EDMC concluded that glasdegib offered no survival benefit in either the INT or NINT 
cohort. There were no unexpected safety findings. 
 
Per Section 9 in Protocol B1371019 Amendment 5, detailed methodology for summary and 
statistical analyses are detailed in the SAP. Per the SAP, the goal of the interim analyses was 
to allow early stopping of the study for futility or efficacy. The EDMC reviewed data before 
the study was unblinded to investigators. Following the EDMC conclusion of futility for both 
cohorts, all investigators and participants on the B1371019 study were unblinded to study 
treatment prior to consenting for Amendment 6. No further study therapy would be given in 
the INT cohort once the standard of care consolidation chemotherapy is completed. No 
further follow-up is required past the mandatory 28 days safety follow-up period. 
 
The purpose of Amendment 6 is to provide continued access to study intervention 
(azacitidine with or without glasdegib), and collection of safety data for eligible participants 
who continue to derive a clinical benefit from study intervention in studies B1371019 and 
B1371012.

2.2. Background 
Study B1371019 was a randomized (1:1), double-blind, multicenter, placebo controlled study 
evaluating intensive chemotherapy with or without glasdegib (PF-04449913) or azacitidine 
with or without glasdegib in participants with previously untreated AML. 
 
The goals of the interim analyses were to allow early stopping of the study for futility or 
efficacy. Following a planned interim analysis on 30 September 2020 for the Intensive 
cohort, Pfizer accepted the Committee’s (EDMC) conclusion that in this trial the randomized 
arm (7+3 intensive chemotherapy [cytarabine + daunorubicin] + glasdegib) would not meet 
the primary objective of improving overall survival with respect to intensive chemotherapy 
alone. No unexpected safety issues were identified. Following EDMC review of the data and 
conclusion, investigators were unblinded to study treatment following the EDMC conclusion. 
The Parent Study B1371012 was a multicenter open label Phase 1b study designed to 
evaluate the safety, efficacy, PK, and PD of glasdegib when combined with azacitidine in 
participants with previously untreated Higher Risk MDS, AML, and CMML. This Phase 1b 
study included 2 components: a safety lead-in cohort and an expansion phase with 2 cohorts. 
Since the B1371012 study is closing, participants who wish to continue treatment may do so 
on Study B1371019 Amendment 6. 
This amendment describes the procedures for NINT cohort participants from B1371019 and 
B1371012 who elect to continue to receive study treatment. The Investigator is to follow the 
guidance below for the conduct of this study. 
 
2.2.1. INT Cohort Population (Investigator Instructions Communicated for Both 
Cohorts Following Amendment 5 Study Design) 
Study participants - consolidation phase: 
• Study participants must be contacted to review treatment therapy. 
• May continue to receive consolidation treatment on study (with or without glasdegib) 
if in the investigator’s clinical judgement the participant is deriving clinical benefit. 
• Participants receiving consolidation treatment on the study (with or without 
glasdegib), must be re-consented by signing the IRB/EC approved consent addendum. 
• Participants who continue study intervention must follow the protocol and have all 
procedures and assessments done. Once treatment ends, study participants will be 
followed for 28 days after last dose or until the date consent is withdrawn, then no 
further follow-up will be required. 
• Once consolidation therapy ends, no further treatment will be given. Following that 
time, no further follow-up is required outside the 28 day safety reporting period (if 
consent is not withdrawn).

Page 17 
 
 
Study participants – post consolidation phase: 
• Participants must end study treatment as soon as possible. 
• Participants must sign the IRB/EC approved consent addendum noting that post 
consolidation treatment will end. 
• Once post-consolidation therapy ends, no further treatment will be given. Participants 
will be followed for 28 days after last dose or until the date consent is withdrawn. 
Following that time, no further follow-up is required. 
Study participants -in follow-up (past 28 day safety reporting period): 
• Participants in either cohort (INT or NINT) must end follow-up procedures in the 
study as soon as possible. 
 
2.3. Benefit/Risk Assessment 
More detailed information about the known and expected benefits and risks and reasonably 
expected AEs of glasdegib may be found in the investigator’s brochure, which is the SRSD 
for this study. The SRSD for azacitidine is the package insert. 
 
2.3.1. Risk Assessment 
Risk assessment will be based on continued monitoring and clinical management as per GCP 
guidelines.

A maximum of 34 unblinded participants from Study B1371019 and 3 participants 
originating from Study B1371012 who continue to derive clinical benefit per the treating 
investigators will be allowed access to the study intervention per Amendment 6. 
 
Amendment 6 is a continuation protocol for NINT cohort participants from Study B1371019 
or Study B1371012. A maximum of 34 participants from Study B1371019 and 3 participants 
from Study B1371012 will continue to receive access to study intervention. 
 
4.2. Scientific Rationale for Study Design 
The scientific rationale is as described in the B1371019 Protocol (Amendment 5, 12 April 
2019) and Study B1371012 Protocol (Amendment 7, 14 June 2018). 
 
4.3. Justification for Dose 
The doses administered to participants have already been established in the B1371019 
Protocol (Amendment 5, 12 April 2019) and Study B1371012 Protocol (Amendment 7, 
14 June 2018). 
 
4.4. End of Study Definition 
A participant is considered to have completed the study if he/she has completed all phases of 
the study, including the 28-day safety follow-up period. 
 
The end of this Study is defined as when all participants have discontinued from study 
treatment and have completed the Safety Follow-up Period. The safety follow-up period is 
defined as 28 days after last dose of last study drug. The study may also be terminated at any 
time at the discretion of the Sponsor. 
 
5. STUDY POPULATION 
This study can fulfill its objectives only if appropriate participants are enrolled. The 
following eligibility criteria are designed to select participants for whom participation in the 
study is considered appropriate. All relevant medical and nonmedical conditions should be 
taken into consideration when deciding whether a particular participant is suitable for this 
protocol. 
 
Prospective approval of protocol deviations to recruitment and enrollment criteria, also 
known as protocol waivers or exemptions, is not permitted.

5.1. Inclusion Criteria 
Participants are eligible to be included in the study only if all of the following criteria apply: 
1. Any participant who continues to demonstrate clinical benefit (as determined by the 
Principal Investigator) from study treatment with azacitidine with or without 
glasdegib in this Study or from Study B1371012. 
2. Capable of giving signed informed consent as described in Appendix 1, which 
includes compliance with the requirements and restrictions listed in the ICD and in 
this protocol. 
 
5.2. Exclusion Criteria 
Participants are excluded from the study if any of the following criteria apply: 
1. Other medical or psychiatric condition including recent (within the past year) or 
active suicidal ideation/behavior or laboratory abnormality that may increase the risk 
of study participation or, in the investigator’s judgment, make the participant 
inappropriate for the study. 
 
2. Female participants who are pregnant or breastfeeding (if continuing to receive study 
intervention); 
 
3. Participant has been withdrawn from Study B1371019 and Study B1371012 for any 
reason (including INT cohort participants required to end study treatment). 
 
5.3. Lifestyle Considerations 
5.3.1. Contraception 
Glasdegib has been associated with teratogenic risk and azacitidine has been shown to cause 
congenital malformations in animals. The investigator or his or her designee, in consultation 
with the participant, will confirm that the participant has selected an appropriate method of 
contraception for the individual participant and his or her partner(s) from the permitted list of 
contraception methods (see Appendix 4 Section 10.4.4) and will confirm that the participant 
has been instructed in its consistent and correct use. At time points indicated in the SoA, the 
investigator or designee will inform the participant of the need to use highly effective 
contraception consistently and correctly and document the conversation and the participant’s 
affirmation in the participant’s chart (participants need to affirm their consistent and correct 
use of at least 1 of the selected methods of contraception). In addition, the investigator or 
designee will instruct the participant to call immediately if the selected contraception method 
is discontinued or if pregnancy is known or suspected in the participant or partner.

5.3.2. Postmenopausal Defined 
A postmenopausal state is defined as no menses for 12 months without an alternative medical 
cause. 
• A high FSH level in the postmenopausal range (as per the reference range used by the 
laboratory) may be used to confirm a postmenopausal state in women under 60 years 
old and not using hormonal contraception or HRT. 
• Females on HRT and whose menopausal status is in doubt will be required to use one 
of the non-estrogen hormonal highly effective contraception methods described in 
Section 10.4.3 if they wish to continue their HRT during the trial. Otherwise, they 
must discontinue HRT to allow confirmation of postmenopausal status before trial 
enrollment. 
 
5.3.3. Sunlight Exposure 
Participants will be advised to report any reaction to sun exposed skin. In addition, special 
precautions will be taken to limit any potential photo irritation effect, by minimizing the 
participants’ exposure to light including high intensity UVB sources such as tanning beds, 
tanning booths and sunlamps. Participants should be encouraged to apply 
sunscreen/sunblock daily. 
 
5.4. Screen Failures 
Participants who do not meet the inclusion/exclusion criteria will not be permitted to 
participate in Amendment 6. See Section 8 regarding screening evaluations. 
 
6. STUDY INTERVENTION 
Study intervention is defined as any investigational intervention(s), marketed product(s), 
placebo, medical device(s), or study procedure(s) intended to be administered to a study 
participant according to the study protocol. 
 
For the purposes of this study, and per ICH guidelines, investigational product is defined as a 
pharmaceutical form of an active ingredient or placebo being tested or used as a reference in 
a clinical trial, including a product with a marketing authorization when used or assembled 
(formulated or packaged) in a way different from the approved form, or when used for an 
unapproved indication, or when used to gain further information about an approved use 
(ICH E6 1.33). For the purpose of this study, the study interventions are glasdegib and 
azacitidine.

6.1.1. Administration 
Both glasdegib and azacitidine are administered in 28-day cycles. Cycle duration maybe 
extended beyond 28 days to allow resolution of toxicities related to study treatments. It is 
suggested that sites contact the participant via phone anytime there is a dose reduction to 
confirm that the participant adequately understands the dosing instructions. 
 
Glasdegib will be self-administered by the participant at home, unless otherwise specified. 
Glasdegib will be administered orally with approximately 8 ounces (240 mL) of water, at the 
same time each day. Tablets must not be crushed or cut; they must be swallowed whole, not 
manipulated or not chewed prior to swallowing. If a participant forgets to take their dose at 
the regularly scheduled time, and if fewer than 10 hours have passed since the scheduled 
dosing time, that dose should be taken as soon as possible. If more than 10 hours have passed 
since the scheduled dosing time, the dose should be skipped, and the participant should 
continue their normal dosing schedule. If a participant misses a day’s dose entirely, they must 
be instructed not to “make it up” the next day. If a participant vomits any time after taking a 
dose, they must be instructed not to “make it up,” but to resume subsequent doses the next 
day as prescribed. If a participant inadvertently takes 1 extra dose during a day, the 

Glasdegib PF-04449913 
Protocol B1371019 
Final Protocol Amendment 6, 02 February 2021 
PFIZER CONFIDENTIAL 
Page 22 
 
 
participant should not take the next dose of glasdegib. The participant will be reminded to 
bring their bottle(s) and participant dosing diary into clinic to evaluate dosing compliance. 
 
Participants requiring glasdegib dose reduction(s) will be administered multiples of 25 mg 
tablets and should continue taking the glasdegib at the same time each day at the dose 
prescribed by the Investigator (ie, 75 mg QD and 50 mg QD in the form of three or two 
25 mg tablets respectively). In situations where clinical benefit is observed, glasdegib can be 
reduced below 50 mg QD upon Sponsor approval. 
 
Dose modifications are discussed in Section 6.6. 
 
Study intervention administration details will be recorded on the CRF. 
 
6.1.2. Dosing Regimen 
• Azacitidine will be administered 75 mg/m2/day for 7 days every 28 days on Days 1-7 
(±3 days) per local label or per the IP Manual (or SPC). Azacitidine may be 
administered by SC injection or IV infusion. Alternate dosing schedules to administer 
the 7 doses to accommodate participant and treatment center availability are allowed. 
The starting dose regimen will be the same as the most recent regimen received on 
the B1371019 or B1371012 study. 
 
• Glasdegib 50, 75 or 100 mg will be orally administered daily and continuously. The 
starting dose regimen will be the same as the most recent regimen received on the 
B1371012 or B1371019 study. 
 
Dose modifications are discussed in Section 6.6. 
 
6.1.3. Treatment Duration 
Treatment with the study treatment should be continued until objective disease progression or 
relapse, death, unacceptable toxicity, or participant refusal, whichever occurs first. 
 
If glasdegib is permanently discontinued for reasons other than objective disease progression, 
participant refusal, or consent withdrawal, single agent treatment with azacitidine may be 
continued if, in the Investigator’s judgment, a clinical benefit has been observed and 
following discussion between the investigator and sponsor. 
 
In cases of unacceptable toxicity or pregnancy, the participant must be withdrawn from study 
treatment. 
 
6.2. Preparation/Handling/Storage/Accountability 
1. The investigator or designee must confirm appropriate temperature conditions have 
been maintained during transit for all study interventions received and any 
discrepancies are reported and resolved before use of the study intervention. 
 
2. Only participants enrolled in the study may receive study intervention and only 
authorized site staff may supply or administer study intervention. All study 

Glasdegib PF-04449913 
Protocol B1371019 
Final Protocol Amendment 6, 02 February 2021 
PFIZER CONFIDENTIAL 
Page 23 
 
 
interventions must be stored in a secure, environmentally controlled, and monitored 
(manual or automated recording) area in accordance with the labeled storage 
conditions with access limited to the investigator and authorized site staff. At a 
minimum, daily minimum and maximum temperatures for all site storage locations 
must be documented and available upon request. Data for nonworking days must 
indicate the minimum and maximum temperatures since previously documented for 
all site storage locations upon return to business. 
 
3. Any excursions from the study intervention label storage conditions should be 
reported to Pfizer upon discovery along with any actions taken. The site should 
actively pursue options for returning the study intervention to the storage conditions 
described in the labeling, as soon as possible. Once an excursion is identified, the 
study intervention must be quarantined and not used until Pfizer provides permission 
to use the study intervention. Specific details regarding the definition of an excursion 
and information the site should report for each excursion will be provided to the site 
in the IP manual. 
 
4. Any storage conditions stated in the SRSD will be superseded by the storage 
conditions stated on the label. 
 
5. Study interventions should be stored in their original containers. 
 
6.  Site staff will instruct participants on the proper storage requirements for take home 
study intervention. 
 
7.  See the package insert, or SPC for storage conditions of the azacitidine once 
reconstituted and/or diluted. 
 
8. The investigator, institution, or the head of the medical institution (where applicable) 
is responsible for study intervention accountability, reconciliation, and record 
maintenance (ie, receipt, reconciliation, and final disposition records), such as the 
IPAL or sponsor-approved equivalent. All study interventions will be accounted for 
using a study intervention accountability form/record. All glasdegib that is taken 
home by the participant, both used and unused bottles/tablets, must be returned to the 
investigator by the participant. Returned study intervention must not be redispensed 
to the participants. 
 
9. Further guidance and information for the final disposition of unused study 
interventions are provided in the IP manual. All destruction must be adequately 
documented. If destruction is authorized to take place at the investigator site, the 
investigator must ensure that the materials are destroyed in compliance with 
applicable environmental regulations, institutional policy, and any special instructions 
provided by Pfizer. 
 
Upon identification of a product complaint, notify the sponsor within 1 business day of 
discovery as described in the IP Manual.

6.2.1. Preparation and Dispensing 
6.2.1.1. Glasdegib 
Glasdegib will be supplied by Pfizer Worldwide Research and Development as 25 mg and 
100 mg tablets for oral administration. Supplies will be labelled according to local regulatory 
requirements. 
 
Glasdegib will be packaged in HDPE bottles and should be handled with care. Each bottle 
will contain enough medication for a 28 day cycle of daily dosing, plus an additional amount 
to cover the time between site visits. Participants should be instructed to keep their 
medication in the bottles provided and not transfer it to any other containers and return the 
bottles to the site at the next study visit. Site personnel must ensure that participants clearly 
understand the directions for self-medication. 
 
Study intervention should be dispensed using the IRT system (IWR) that provides a 
confirmation report containing the participant identification number and DU(s) or container 
number(s) assigned by an appropriately qualified and experienced member of the study staff 
(eg, physician, nurse, physician’s assistant, practitioner, or pharmacist) as allowed by local, 
state, and institutional guidance. The confirmation report must be stored in the site’s files. 
 
The study specific IRT reference manual will provide the contact information and further 
details on the use of the IRT system. 
 
6.2.1.2. Azacitidine 
Azacitidine 25 mg/mL powder for suspension for injection will be used in this study. Please 
refer to the local package insert (or SPC) or the IP manual for detailed formulation, 
preparation and IV and SC administration instructions. 
 
Only qualified personnel who are familiar with procedures that minimize undue exposure to 
them and to the environment should undertake the preparation, handling, and safe disposal of 
chemotherapeutic agents. 
 
If azacitidine is provided by sponsor, it should be dispensed using the IRT system that 
provides a confirmation report containing the participant identification number and DU(s) or 
container number(s) assigned by an appropriately qualified and experienced member of the 
study staff (eg, physician, nurse, physician’s assistant, practitioner, or pharmacist) as allowed 
by local, state, and institutional guidance. The confirmation report must be stored in the site’s 
files. 
 
6.3. Measures to Minimize Bias: Randomization and Blinding 
Randomization and blinding are not applicable to this protocol amendment. Participants on 
Study B1371019 will be unblinded prior to dosing on Amendment 6. 

Glasdegib PF-04449913 
Protocol B1371019 
Final Protocol Amendment 6, 02 February 2021 
PFIZER CONFIDENTIAL 
Page 25 
 
 
6.4. Study Intervention Compliance 
The investigator’s site must maintain adequate records documenting the receipt, use, loss, or 
other disposition of the drug supplies. At each dispensing visit (Cycle 2 Day 1, 
Cycle 3 Day 1, etc. or when there is a dose reduction), all unused or partially used bottles 
must be returned by participants to the Investigator. The number of tablets returned by the 
participant at the end of the cycle will be counted, documented and recorded. 
 
The sponsor or designee will provide guidance on the destruction of unused investigational 
product (eg, at the site). If destruction is authorized to take place at the study site, the 
investigator must ensure that the materials are destroyed in compliance with applicable 
environmental regulations, institutional policy, and any special instructions provided by 
sponsor or designee and all destruction must be adequately documented. 
 
For azacitidine, the site should complete the required dosage Preparation Record located in 
the Investigational Product Manual. The use of the Preparation Record is preferred but it 
does not preclude the use of an existing appropriate clinical site documentation system. The 
existing clinical site's documentation system should capture all pertinent/required 
information on the preparation and administration of the dose including the methodology 
used to calculate the participant body surface area. This may be used in place of the 
Preparation Record after approval from the Sponsor. 
 
6.5. Concomitant Therapy 
Concomitant medications will be assessed at screening and all clinic visits. 
 
Concomitant treatment considered necessary for the participant’s well-being may be given at 
discretion of the treating physician. If a participant is offered, in accordance with the 
prevailing local guidelines, a COVID-19 vaccine, it should be permitted. This would be 
recorded as a concomitant medication in the medical records and standard AE collection and 
reporting processes would be followed. 
 
6.5.1. Restricted or Prohibited Concomitant Medications 
The following medications are not allowed during the active study treatment period: 
• Agents used to treat AML or MDS; 
• Investigational agents; This exclusion does not apply to any COVID-19 vaccine. 
• CYP3A4/5 Strong Inducers: A drug-drug interaction study in healthy participants 
with the strong CYP3A4 inducer, rifampin, resulted in a 70% decrease in plasma 
exposures (AUCinf) and a 35% decrease in peak plasma concentration (Cmax) of a 
single 100 mg oral dose of glasdegib. Therefore, coadministration of glasdegib and 
strong CYP3A4/5 inducers is not permitted. A comprehensive list of strong 
CYP3A4/5 inducers is provided in Appendix 9. The Sponsor study team should be 
contacted if there is uncertainty whether a concomitant medication is contraindicated. 
• CYP3A4/5 Moderate Inducers (Appendix 9): Avoid concomitant use of glasdegib 
with moderate CYP3A4 inducers. If use cannot be avoided, double the glasdegib 

Glasdegib PF-04449913 
Protocol B1371019 
Final Protocol Amendment 6, 02 February 2021 
PFIZER CONFIDENTIAL 
Page 26 
 
 
dose, as tolerated. After the moderate CYP3A4 inducer has been discontinued for 
7 days, resume glasdegib dose taken prior to initiating the moderate CYP3A4 inducer. 
The following medications have use restrictions during the active study treatment period: 
• CYP3A4/5 Inhibitors: In a healthy volunteer study, ketoconazole, a potent 
CYP3A4/5 inhibitor, produced a 2.4 fold increase in plasma exposure and a 1.4 fold 
increase in peak plasma concentration of glasdegib. Therefore, a potential exists for 
drug-drug interactions with CYP3A4/5 inhibitors, and coadministration of 
glasdegib in combination with strong/ moderate CYP3A4/5 inhibitors is not 
recommended. Selection of concomitant medication with no or minimal 
CYP3A4/5 inhibition potential is recommended. Strong/moderate 
CYP3A4/5 inhibitors (Appendix 10 or Appendix 11) should be used with caution and 
only if considered medically necessary. If a moderate/strong CYP3A4/5 inhibitor is to 
be initiated in addition to glasdegib, the guidance provided in Appendix 6. 
• Drugs with a known risk of TdP: Glasdegib has been shown to have the potential to 
prolong the QTc interval in preclinical studies. In the first in participant study as 
single agent, Grade 3 QTcF prolongation was observed at the highest doses tested 
(400 mg and 600 mg). While the glasdegib dose evaluated in this study is 100 mg, the 
concomitant administration of glasdegib and drugs with a known risk of Tdp should 
be avoided whenever possible. A list of such drugs is provided in Appendix 12. Use 
of these drugs is not recommended unless there are no alternatives. If a TdP drug is to 
be initiated in addition to glasdegib the guidance provided in Section 6.6.1 dose 
modifications for QT prolongation per Table 3 must be followed. 
• QT prolonging medications (without a risk of TdP) should be avoided whenever 
possible. 
• Concomitant administration of multiple moderate/strong CYP3A4/5 inhibitors, TdP 
drugs, and/or QT prolonging medications (without a risk of TdP) is not 
recommended. 
 
6.5.2. Permitted Concomitant Medications 
6.5.2.1. Best Supportive Therapy 
BST administration is permitted according to institutional guidelines for all participants on 
study. BST will be provided by the site and may vary depending on the participant’s signs 
and symptoms, site current practice, and country practice. It includes medications and 
supportive measures that may palliate disease related symptoms, improve quality of life and 
treat bacterial, fungal or viral infections. BST may include: 
• Blood transfusions; 
• Platelet transfusions; 
• Antibiotics; 
• Antifungal agents; 
• Antiviral agents.

6.5.2.2. Hematopoietic Growth Factors 
Hematopoietic growth factors (eg, G-CSF, GM-CSF) may be used according to local practice 
and guidelines. 
6.5.2.3. Antiemetic and Antidiarrheal Therapy 
Participants should be pre-medicated with anti-emetics for nausea and vomiting before each 
dose of azacitidine in all cycles according to local practice and guidelines. 
 
Primary prophylaxis of diarrhea is permitted at the Investigator’s discretion. The choice of 
the prophylactic drug is up to the investigator assuming the drug is not contraindicated as 
described in Section 6.5.1. 
 
6.5.3. Surgery 
Caution is advised on theoretical grounds for any surgical procedures during the study. The 
appropriate interval of time between surgery and glasdegib required to minimize the risk of 
impaired wound healing and bleeding has not been determined. Stopping glasdegib is 
recommended at least 7 days prior to surgery. Post-operatively, the decision to reinitiate 
glasdegib treatment is up to the Investigator with Sponsor approval and should be based on a 
clinical assessment of satisfactory wound healing and recovery from surgery. 
 
6.5.4. HSCT 
Participants who are eligible for HSCT will undergo HSCT per local standard of care. 
 
For post disease remission HSCT, glasdegib will be interrupted at least 28 days before HSCT 
(date of stem cell infusion). 
 
Glasdegib may be resumed 30-60 days post HSCT once there is ANC engraftment, no 
≥ Grade 2 ongoing GVHD, and no ongoing SAEs in the judgement of the investigator. 
6.6. Dose Modification 
Every effort should be made to administer the study drug treatment according to the planned 
dose and schedule. 
 
In the event of Grade 3 or Grade 4 non-hematologic, study-treatment-related toxicity, dosing 
may be delayed and/or dose reduced. The glasdegib dose should be reduced 1 dose level at a 
time, in increments of 25 mg (75 mg QD, 50 mg QD, in the form of 3 or 2 x 25 mg tablets 
respectively). Glasdegib does not need to be delayed or dose reduced for hematologic, study- 
treatment-related toxicity. 
 
Glasdegib may be interrupted or permanently discontinued for any reason as per GCP. 
Glasdegib should be permanently discontinued if: 
interruptions are for more than 28 consecutive days when not required by the protocol (ie, 
HSCT period).

Dose escalations will not be allowed following glasdegib/placebo dose reductions. Dose 
modifications may occur in 3 ways: 
 
Within a cycle: Dosing interruption until adequate recovery followed by dose reduction 
(if required) of glasdegib during a given treatment cycle. 
 
Between cycles: The next treatment cycle may be delayed if toxicity from the preceding 
cycle persists. 
 
In the next cycle: Dose reduction may be required based on toxicities experienced in the 
previous cycle. 
 
When chemotherapy is given, a Cycle is determined by chemotherapy administration 
schedule. A Cycle is 28 days, but will be extended if there are dose delays or modifications 
in the chemotherapy backbone. 
6.6.1. Glasdegib 
Glasdegib does not need to be delayed or dose reduced for hematologic toxicity deemed 
unrelated/unlikely related to glasdegib by the investigator. 
Participants experiencing Grade 3 or 4 nonhematological toxicities potentially attributable to 
glasdegib should have their glasdegib treatment interrupted regardless of when it occurs in 
the cycle until the toxicity resolves or returns to baseline or <Grade 1, as described in 
Table 2. If these parameters have not been met following >28 consecutive days of dose 
interruption, glasdegib should be permanently discontinued. If glasdegib treatment is 
permanently discontinued, participants may continue single agent treatment with azacitidine, 
if according to the investigator’s judgment a clinical benefit has been observed, and 
following discussion between the investigator and the sponsor. 
Appropriate follow-up assessments should be implemented until adequate recovery (toxicity 
resolves or returns to baseline) occurs. 
Depending on when the adverse event resolved, treatment interruption may lead to the 
participant missing all subsequent planned doses of glasdegib within the cycle. If the AE 
leading to treatment interruption recovers within the same cycle, recommencement of dosing 
in that cycle is allowed. The need for a dose reduction at the time of treatment resumption 
should be based on the criteria outlined in Table 2, unless specifically agreed otherwise 
following discussion between the investigator and the sponsor. If a dose reduction for 
glasdegib is applied in the same cycle, the participant may need to receive a new supply of 
drug. Glasdegib doses omitted for toxicity will not be replaced within that cycle (eg, cycles 
will not be prolonged beyond the 28 days to make up for any missed glasdegib doses during 
that cycle). 
Glasdegib may be interrupted or permanently discontinued for any reason as per GCP. 
Glasdegib should be permanently discontinued if interruptions are for more than 28 
consecutive days. In the event of glasdegib treatment interruption for reasons other than 

Glasdegib PF-04449913 
Protocol B1371019 
Final Protocol Amendment 6, 02 February 2021 
PFIZER CONFIDENTIAL 
Page 29 
 
 
treatment-related toxicity (eg, elective surgery) for a duration >28 days, the details of 
treatment resumption will be determined in consultation with the Sponsor. 
Dose reduction of glasdegib by 1 or, if necessary, 2 dose levels (Table 1) will be allowed 
depending on the type and severity of toxicity encountered. NOTE: In the specific situations 
where clinical benefit is observed, glasdegib can be reduced below 50 mg QD upon 
discussion with the sponsor. All dose modifications/adjustments must be clearly documented 
in the participant's notes and eCRF. 
Once the glasdegib dose has been reduced, all subsequent cycles should be administered at 
that dose level, unless further dose reduction is required. Dose re-escalation is not allowed. 
Deviations from any of the dose modifications must be discussed and agreed with the 
sponsor Medical Monitor.

Participants will be closely monitored for potential cardiovascular symptoms per standard of 
care. Appropriate monitoring should include clinical examinations, vital signs, routine ECGs, 
and AE monitoring. In case of QTcF prolongation, concomitant conditions such as 
electrolyte imbalances, hypoxia, or use of medications affecting the QT interval should be 
ruled out and/or corrected. In case of clinically significant toxicities, glasdegib administration 
should be interrupted and the dose reduced as indicated in Table 3. 
 
Concomitant administration of glasdegib with strong/moderate CYP3A4/5 inhibitors 
(Appendix 10 or Appendix 11) and drugs with known risk of TdP (Appendix 12) is not 
recommended due to the potential for drug-drug interaction to prolong the QTc interval. 
However, if it is medically necessary for participants to use these medications please refer to 
Appendix 6 for monitoring procedures. Investigators must be aware of the QTcF prolonging 
potential of all medications that participants on study are taking, and should take appropriate 
action when clinically indicated. Given the potential for QTcF prolongation, the 
measurement and immediate correction of electrolyte abnormalities such as potassium and 
magnesium, and of other reversible causes of QTcF prolongation such as hypoxia, are 
especially important. In the event that the QTcF interval is prolonged beyond 480 msec 
(CTCAE v. 4.03 ≥Grade 2), Table 3 must be referenced and actioned. Additional ECG and 
cardiac consultation should be obtained if clinically indicated.

7. DISCONTINUATION OF STUDY INTERVENTION AND PARTICIPANT 
DISCONTINUATION/WITHDRAWAL 
7.1. Discontinuation of Study Intervention 
In rare instances, it may be necessary for a participant to permanently discontinue study 
intervention (definitive discontinuation). Reasons for definitive discontinuation of study 
intervention may include the following: 
 
• Objective disease progression or relapse 
• Participant refusal 
• Consent withdrawal 
• Unacceptable toxicity 
• Pregnancy 
• Initiation of another anti-cancer treatment 
If study intervention is definitively discontinued, the participant will not remain in the study 
for further evaluation. See the SoA for data to be collected at the time of discontinuation of 
study intervention. 

Glasdegib PF-04449913 
Protocol B1371019 
Final Protocol Amendment 6, 02 February 2021 
PFIZER CONFIDENTIAL 
Page 33 
 
 
Note that discontinuation of study intervention does not represent withdrawal from the study. 
If study intervention is definitively discontinued, the participant will remain in the study to 
be evaluated for 28 calendar days after the last dose of study treatment administration. See 
the SoA for data to be collected at the time of discontinuation of study intervention and 
follow-up for any further evaluations that need to be completed. 
 
In the event of discontinuation of study intervention, it must be documented on the 
appropriate CRF/in the medical records whether the participant is discontinuing further 
receipt of study intervention or also from study procedures, posttreatment study follow-up, 
and/or future collection of additional information. 
 
7.2. Participant Discontinuation/Withdrawal From the Study 
A participant may withdraw from the study at any time at his/her own request. Reasons for 
discontinuation from the study may include the following: 
• Refused further follow-up; 
• Lost to follow-up; 
• Death; 
• Study terminated by sponsor; 
• Progressive Disease; 
• Pregnancy; 
• Global deterioration of health status; 
• Unacceptable toxicity 
• Withdrawal of consent; 
• Significant noncompliance. 
The participant will be permanently discontinued both from the study intervention and from 
the study at that time. 
 
If a participant withdraws from the study, he/she may request destruction of any remaining 
samples taken and not tested, and the investigator must document any such requests in the 
site study records and notify the sponsor accordingly. 
 
If the participant withdraws from the study and also withdraws consent (see Section 7.2.1) 
for disclosure of future information, no further evaluations should be performed and no 
additional data should be collected. The sponsor may retain and continue to use any data 
collected before such withdrawal of consent. 
 
Lack of completion of all or any of the withdrawal/early termination procedures will not be 
viewed as protocol deviations so long as the participant’s safety was preserved. 

Glasdegib PF-04449913 
Protocol B1371019 
Final Protocol Amendment 6, 02 February 2021 
PFIZER CONFIDENTIAL 
Page 34 
 
 
7.2.1. Withdrawal of Consent 
Participants who request to discontinue receipt of study intervention will remain in the study 
and must continue to be followed for protocol-specified follow-up procedures. The only 
exception to this is when a participant specifically withdraws consent for any further contact 
with him or her or persons previously authorized by the participant to provide this 
information. Participants should notify the investigator in writing of the decision to withdraw 
consent from future follow-up, whenever possible. The withdrawal of consent should be 
explained in detail in the medical records by the investigator, as to whether the withdrawal is 
only from further receipt of study intervention or also from study procedures and/or 
posttreatment study follow-up, and entered on the appropriate CRF page. In the event that 
vital status (whether the participant is alive or dead) is being measured, publicly available 
information should be used to determine vital status only as appropriately directed in 
accordance with local law. 
 
7.3. Lost to Follow-up 
A participant will be considered lost to follow-up if he or she repeatedly fails to return for 
scheduled visits and is unable to be contacted by the study site. 
 
The following actions must be taken if a participant fails to return to the clinic for/attend a 
required study visit: 
 
The site must attempt to contact the participant and reschedule the missed visit as soon as 
possible and counsel the participant on the importance of maintaining the assigned visit 
schedule and ascertain whether or not the participant wishes to and/or should continue in the 
study; 
 
Before a participant is deemed lost to follow-up, the investigator or designee must make 
every effort to regain contact with the participant (where possible, 3 telephone calls and, if 
necessary, a certified letter to the participant’s last known mailing address or local equivalent 
methods). These contact attempts should be documented in the participant’s medical record; 
 
Should the participant continue to be unreachable, he/she will be considered to have 
withdrawn from the study. 
 
8. STUDY ASSESSMENTS AND PROCEDURES 
The investigator (or an appropriate delegate at the investigator site) must obtain a signed and 
dated ICD before performing any study-specific procedures. 
 
Study procedures and their timing are summarized in the SoA. Protocol waivers or 
exemptions are not allowed. Refer to Appendix 7 for alternative measures during the 
COVID-19 pandemic. 
 
Safety issues should be discussed with the sponsor immediately upon occurrence or 
awareness to determine whether the participant should continue or discontinue study 
intervention. 

Glasdegib PF-04449913 
Protocol B1371019 
Final Protocol Amendment 6, 02 February 2021 
PFIZER CONFIDENTIAL 
Page 35 
 
 
Adherence to the study design requirements, including those specified in the SoA, is essential 
and required for study conduct. 
 
All screening evaluations must be completed and reviewed to confirm that potential 
participants meet all eligibility criteria. The investigator will maintain a screening log to 
record details of all participants screened and to confirm eligibility or record reasons for 
screening failure, as applicable. 
 
Every effort should be made to ensure that -protocol-required tests and procedures are 
completed as described. However, it is anticipated that from time to time there may be 
circumstances outside the control of the investigator that may make it unfeasible to perform 
the test. In these cases, the investigator must take all steps necessary to ensure the safety and 
well-being of the participant. When a -protocol-required test cannot be performed, the 
investigator will document the reason for the missed test and any corrective and preventive 
actions that he or she has taken to ensure that required processes are adhered to as soon as 
possible. The study team must be informed of these incidents in a timely manner. 
 
For samples being collected and shipped, detailed collection, processing, storage, and 
shipment instructions and contact information will be provided to the investigator site prior 
to initiation of the study. 
 
8.1. Efficacy Assessments 
Not applicable. 
 
8.2. Safety Assessments 
Planned time points for all safety assessments are provided in the SoA. Unscheduled clinical 
laboratory measurements may be obtained at any time during the study to assess any 
perceived safety issues. 
 
8.2.1. Physical Examinations/Vital Signs/ECG 
Physical examinations and vital signs will be performed as per standard of care at the Study 
Center but will not be recorded in the CRF. A finding representing an AE will be recorded in 
the AE CRF as described in Section 8.3.1. 
 
ECG values of potential clinical concern are listed in Appendix 6: ECG. 
 
8.2.2. Clinical Safety Laboratory Assessments 
Timing and frequency of clinical safety laboratory tests are to be performed per standard of 
care and at any time during the study to assess any perceived safety issues. Appendix 2 
includes laboratory tests recommended to determine dosing eligibility. 
 
The investigator must review the laboratory report, document this review, and record any 
clinically relevant changes occurring during the study in the AE section of the CRF. 
Clinically significant abnormal laboratory findings are those which are not associated with 

Glasdegib PF-04449913 
Protocol B1371019 
Final Protocol Amendment 6, 02 February 2021 
PFIZER CONFIDENTIAL 
Page 36 
 
 
the underlying disease, unless judged by the investigator to be more severe than expected for 
the participant's condition. 
 
All laboratory tests with values considered clinically significantly abnormal during 
participation in the study or within 28 days after the last dose of study intervention should be 
repeated until the values return to normal or baseline or are no longer considered clinically 
significant by the investigator or medical monitor. 
 
If such values do not return to normal/baseline within a period of time judged reasonable by 
the investigator, the etiology should be identified and the sponsor notified. 
 
See Appendix 5 for suggested actions and follow-up assessments in the event of potential 
drug-induced liver injury. 
 
8.2.3. Pregnancy Testing 
Pregnancy tests may be urine or serum tests, but must have a sensitivity of at least 
25 mIU/mL. Pregnancy tests will be performed in WOCBP at the times listed in the SoA. 
Following a negative pregnancy test result at screening, appropriate contraception must be 
commenced, and a second negative pregnancy test result will be required at the baseline visit 
prior the participant’s receiving the study intervention/study treatment. Pregnancy tests will 
also be done whenever 1 menstrual cycle is missed during the active treatment period (or 
when potential pregnancy is otherwise suspected) and at the end of the study treatment. 
Pregnancy tests may also be repeated if requested by IRBs/ECs or if required by local 
regulations. If a urine test cannot be confirmed as negative (eg, an ambiguous result), a serum 
pregnancy test is required. In such cases, the participant must be excluded if the serum 
pregnancy result is positive. 
 
8.2.4. Disease Assessment 
Imaging and tumor assessments will be conducted per the site’s standard of care and will not 
be recorded in the CRF. A finding representing an AE will be recorded in the AE CRF as 
described in Section 8.3.1. 
 
8.2.5. One Month Safety Follow-up 
For follow-up procedures see SoA and Section 8. 
 
Study participants will be followed for 28 calendar days after the last administration of study 
treatment to capture any potential AEs leading to permanent study treatment 
discontinuation/SAEs. 
 
In the event a participant is unable to return to the clinic for the follow-up visit, telephone 
contact with the participant to assess AEs and treatment is expected. If laboratory 
assessments are needed to follow up unresolved AEs, retrieval of assessments performed at 
an institution local to the participant is acceptable. No further follow-up is required after the 
28 day safety reporting period.

8.3. Adverse Events and Serious Adverse Events 
The definitions of an AE and an SAE can be found in Appendix 3. 
 
AEs will be reported by the participant (or, when appropriate, by a caregiver, surrogate, or 
the participant's legally authorized representative). 
 
The investigator and any qualified designees are responsible for detecting, documenting, and 
recording events that meet the definition of an AE or SAE and remain responsible to pursue 
and obtain adequate information both to determine the outcome and to assess whether the 
event meets the criteria for classification as an SAE or caused the participant to discontinue 
the study intervention (see Section 7.1). 
 
Each participant/parent/legal guardian/legally authorized representative will be questioned 
about the occurrence of AEs in a nonleading manner. 
 
In addition, the investigator may be requested by Pfizer Safety to obtain specific follow-up 
information in an expedited fashion. 
 
8.3.1. Time Period and Frequency for Collecting AE and SAE Information 
The time period for actively eliciting and collecting AEs and SAEs (“active collection 
period”) for each participant begins from the time the participant provides informed consent, 
which is obtained before the participant’s participation in the study (ie, before undergoing 
any study-related procedure and/or receiving study intervention), through and including a 
minimum of 28 calendar days after the last administration of the study intervention. 
 
Follow-up by the investigator continues throughout and after the active collection period and 
until the AE or SAE or its sequelae resolve or stabilize at a level acceptable to the 
investigator and Pfizer concurs with that assessment. 
 
For participants who are screen failures, the active collection period ends when screen failure 
status is determined. 
 
If the participant withdraws from the study and also withdraws consent for the collection of 
future information, the active collection period ends when consent is withdrawn. 
 
If a participant definitively discontinues or temporarily discontinues study intervention 
because of an AE or SAE, the AE or SAE must be recorded on the CRF and the SAE 
reported using the CT SAE Report Form. 
 
Investigators are not obligated to actively seek AEs or SAEs after the participant has 
concluded study participation. However, if the investigator learns of any SAE, including a 
death, at any time after a participant has completed the study, and he/she considers the event 
to be reasonably related to the study intervention, the investigator must promptly report the 
SAE to Pfizer using the CT SAE Report Form.

8.3.1.1. Reporting SAEs to Pfizer Safety 
All SAEs occurring in a participant during the active collection period as described in 
Section 8.3.1 are reported to Pfizer Safety on the CT SAE Report Form immediately upon 
awareness and under no circumstance should this exceed 24 hours, as indicated in 
Appendix 3. The investigator will submit any updated SAE data to the sponsor within 
24 hours of it being available. 
 
If a participant begins a new anticancer therapy, SAEs occurring during the above -indicated 
active collection period must still be reported to Pfizer Safety irrespective of any intervening 
treatment. Note that a switch to a commercially available version of the study intervention is 
considered as a new anticancer therapy for the purposes of SAE reporting. 
 
8.3.1.2. Recording Nonserious AEs and SAEs on the CRF 
All nonserious AEs and SAEs occurring in a participant during the active collection period, 
which begins after obtaining informed consent as described in Section 8.3.1, will be recorded 
on the AE section of the CRF. 
 
The investigator is to record on the CRF all directly observed and all spontaneously reported 
AEs and SAEs reported by the participant. 
 
If a participant begins a new anticancer therapy, the recording period for nonserious AEs 
ends at the time the new treatment is started; however, SAEs must continue to be recorded on 
the CRF during the above-indicated active collection period. Note that a switch to a 
commercially available version of the study intervention is considered as a new anticancer 
therapy for the purposes of SAE reporting. 
 
8.3.2. Method of Detecting AEs and SAEs 
The method of recording, evaluating, and assessing causality of AEs and SAEs and the 
procedures for completing and transmitting SAE reports are provided in Appendix 3. 
 
Care will be taken not to introduce bias when detecting AEs and/or SAEs. Open-ended and 
nonleading verbal questioning of the participant is the preferred method to inquire about 
AE occurrences. 
 
8.3.3. Follow-up of AEs and SAEs 
After the initial AE/SAE report, the investigator is required to proactively follow each 
participant at subsequent visits/contacts. For each event, the investigator must pursue and 
obtain adequate information until resolution, stabilization, the event is otherwise explained, 
or the participant is lost to follow-up (as defined in Section 7.3). 
 
In general, follow-up information will include a description of the event in sufficient detail to 
allow for a complete medical assessment of the case and independent determination of 
possible causality. Any information relevant to the event, such as concomitant medications 
and illnesses, must be provided. In the case of a participant death, a summary of available 
autopsy findings must be submitted as soon as possible to Pfizer Safety.

Page 39 
 
 
Further information on follow-up procedures is given in Appendix 3. 
 
8.3.4. Regulatory Reporting Requirements for SAEs 
Prompt notification by the investigator to the sponsor of an SAE is essential so that legal 
obligations and ethical responsibilities towards the safety of participants and the safety of a 
study intervention under clinical investigation are met. 
 
The sponsor has a legal responsibility to notify both the local regulatory authority and other 
regulatory agencies about the safety of a study intervention under clinical investigation. The 
sponsor will comply with country-specific regulatory requirements relating to safety 
reporting to the regulatory authority, IRBs/ECs, and investigators. 
 
Investigator safety reports must be prepared for SUSARs according to local regulatory 
requirements and sponsor policy and forwarded to investigators as necessary. 
 
An investigator who receives SUSARs or other specific safety information (eg, summary or 
listing of SAEs) from the sponsor will review and then file it along with the SRSD(s) for the 
study and will notify the IRB/EC, if appropriate according to local requirements. 
 
8.3.5. Exposure During Pregnancy or Breastfeeding, and Occupational Exposure 
Exposure to the study intervention under study during pregnancy or breastfeeding and 
occupational exposure are reportable to Pfizer Safety within 24 hours of investigator 
awareness. 
 
8.3.5.1. Exposure During Pregnancy 
An EDP occurs if: 
• A female participant is found to be pregnant while receiving or after discontinuing 
study intervention. 
• A male participant who is receiving or has discontinued study intervention exposes a 
female partner prior to or around the time of conception. 
• A female is found to be pregnant while being exposed or having been exposed to 
study intervention due to environmental exposure. Below are examples of 
environmental exposure during pregnancy: 
• A female family member or healthcare provider reports that she is pregnant after 
having been exposed to the study intervention by ingestion or skin contact. 
 
• A male family member or healthcare provider who has been exposed to the study 
intervention by ingestion or skin contact then exposes his female partner prior to 
or around the time of conception. 
 
The investigator must report EDP to Pfizer Safety within 24 hours of the investigator’s 
awareness, irrespective of whether an SAE has occurred. The initial information submitted 

Glasdegib PF-04449913 
Protocol B1371019 
Final Protocol Amendment 6, 02 February 2021 
PFIZER CONFIDENTIAL 
Page 40 
 
 
should include the anticipated date of delivery (see below for information related to 
termination of pregnancy). 
• If EDP occurs in a participant or a participant’s partner, the investigator must report 
this information to Pfizer Safety on the CT SAE Report Form and an EDP 
Supplemental Form, regardless of whether an SAE has occurred. Details of the 
pregnancy will be collected after the start of study intervention and until 5 terminal 
half-lives after the last dose. 
• If EDP occurs in the setting of environmental exposure, the investigator must report 
information to Pfizer Safety using the CT SAE Report Form and EDP Supplemental 
Form. Since the exposure information does not pertain to the participant enrolled in 
the study, the information is not recorded on a CRF; however, a copy of the 
completed CT SAE Report Form is maintained in the investigator site file. 
 
Follow-up is conducted to obtain general information on the pregnancy and its outcome for 
all EDP reports with an unknown outcome. The investigator will follow the pregnancy until 
completion (or until pregnancy termination) and notify Pfizer Safety of the outcome as a 
follow-up to the initial EDP Supplemental Form. In the case of a live birth, the structural 
integrity of the neonate can be assessed at the time of birth. In the event of a termination, the 
reason(s) for termination should be specified and, if clinically possible, the structural 
integrity of the terminated fetus should be assessed by gross visual inspection (unless 
preprocedural test findings are conclusive for a congenital anomaly and the findings are 
reported). 
 
Abnormal pregnancy outcomes are considered SAEs. If the outcome of the pregnancy meets 
the criteria for an SAE (ie, ectopic pregnancy, spontaneous abortion, intrauterine fetal 
demise, neonatal death, or congenital anomaly in a live-born baby, a terminated fetus, an 
intrauterine fetal demise, or a neonatal death), the investigator should follow the procedures 
for reporting SAEs. Additional information about pregnancy outcomes that are reported to 
Pfizer Safety as SAEs follows: 
 
• Spontaneous abortion including miscarriage and missed abortion; 
• Neonatal deaths that occur within 1 month of birth should be reported, without regard 
to causality, as SAEs. In addition, infant deaths after 1 month should be reported as 
SAEs when the investigator assesses the infant death as related or possibly related to 
exposure to the study intervention. 
 
Additional information regarding the EDP may be requested by the sponsor. Further follow- 
up of birth outcomes will be handled on a case by case basis (eg, follow-up on preterm 
infants to identify developmental delays). In the case of paternal exposure, the investigator 
will provide the participant with the Pregnant Partner Release of Information Form to deliver 
to his partner. The investigator must document in the source documents that the participant 
was given the Pregnant Partner Release of Information Form to provide to his partner.

8.3.5.2. Exposure During Breastfeeding 
An exposure during breastfeeding occurs if: 
• A female participant is found to be breastfeeding while receiving or after 
discontinuing study intervention. 
• A female is found to be breastfeeding while being exposed or having been exposed to 
study intervention (ie, environmental exposure). An example of environmental 
exposure during breastfeeding is a female family member or healthcare provider who 
reports that she is breastfeeding after having been exposed to the study intervention 
by inhalation or skin contact. 
 
The investigator must report exposure during breastfeeding to Pfizer Safety within 24 hours 
of the investigator’s awareness, irrespective of whether an SAE has occurred. The 
information must be reported using the CT SAE Report Form. When exposure during 
breastfeeding occurs in the setting of environmental exposure, the exposure information does 
not pertain to the participant enrolled in the study, so the information is not recorded on a 
CRF. However, a copy of the completed CT SAE Report Form is maintained in the 
investigator site file. 
 
An exposure during breastfeeding report is not created when a Pfizer drug specifically 
approved for use in breastfeeding women (eg, vitamins) is administered in accord with 
authorized use. However, if the infant experiences an SAE associated with such a drug, the 
SAE is reported together with the exposure during breastfeeding. 
 
8.3.5.3. Occupational Exposure 
An occupational exposure occurs when a person receives unplanned direct contact with the 
study intervention, which may or may not lead to the occurrence of an AE. Such persons may 
include healthcare providers, family members, and other roles that are involved in the trial 
participant’s care. 
 
The investigator must report occupational exposure to Pfizer Safety within 24 hours of the 
investigator’s awareness, regardless of whether there is an associated SAE. The information 
must be reported using the CT SAE Report Form. Since the information does not pertain to a 
participant enrolled in the study, the information is not recorded on a CRF; however, a copy 
of the completed CT SAE Report Form is maintained in the investigator site file. 
 
8.3.6. Cardiovascular and Death Events 
Not applicable. 
 
8.3.7. Disease-Related Events and/or Disease-Related Outcomes Not Qualifying as AEs 
or SAEs 
Not applicable.

Medication errors 
All (regardless of whether 
associated with an AE) 
Only if associated with an SAE 
 
Medication errors include: 
• Medication errors involving participant exposure to the study intervention; 
• Potential medication errors or uses outside of what is foreseen in the protocol that do 
or do not involve the study participant. 
• If the dose administered is >120% of the scheduled dose, <80% of the scheduled 
dose, or dosed outside a 28 day window. If the drug is administered as incorrect 
formulation (ie, pills cut in half instead of administering a lower dosage tablet, pills 
crushed and administered via feeding tube without direction from Sponsor). 
Such medication errors occurring to a study participant are to be captured on the medication 
error page of the CRF. 
 
Medication errors will NOT include: 
• Cases where commercial backbone drug was used instead of supplied stock; 
• Cases where the wrong lot number of drug was dispensed; 
• Dose modifications outlined in Section 6.6. 
In the event of a medication dosing error, the sponsor should be notified within 24 hours. 

Glasdegib PF-04449913 
Protocol B1371019 
Final Protocol Amendment 6, 02 February 2021 
PFIZER CONFIDENTIAL 
Page 43 
 
 
Whether or not the medication error is accompanied by an AE, as determined by the 
investigator, the medication error is recorded on the medication error page of the CRF and, if 
applicable, any associated AE(s), serious and nonserious, are recorded on the AE page of the 
CRF. 
 
Medication errors should be reported to Pfizer Safety within 24 hours on a CT SAE Report 
Form only when associated with an SAE. 
 
8.3.11. Protocol-Specified Serious Adverse Events 
All cases of Grade 3 or 4 mQTcF prolongation regardless of causality and treatment arm 
must be reported as an SAE for up to 28 calendar days after the last dose of study drug 
administered. All SAEs will be reported to Pfizer Safety by the investigator as described in 
previous sections, and will be handled as SAEs in the safety database. 
 
8.4. Treatment of Overdose 
For this study, an overdose is considered >120% of the scheduled dose of study treatment. 
 
There is no specific treatment for an overdose. Management of glasdegib overdose should 
include symptomatic treatment and ECG monitoring. 
 
In the event of an overdose, the investigator should: 
 
1. Contact the medical monitor within 24 hours. 
 
2. Closely monitor the participant for any AEs/SAEs and laboratory abnormalities for at 
least 5 half-lives or 28 calendar days after the overdose of study intervention 
(whichever is longer). Closely monitor the participant for any AEs/SAEs. 
 
3. Document the quantity of the excess dose as well as the duration of the overdose in 
the CRF. 
 
4. Overdose is reportable to Safety only when associated with an SAE. 
 
Decisions regarding dose interruptions or modifications will be made by the investigator in 
consultation with the medical monitor based on the clinical evaluation of the participant. 
 
8.5. Pharmacokinetics 
No pharmacokinetic assessments will be conducted. 
 
8.6. Pharmacodynamics

All parties will comply with all applicable laws, including laws regarding the implementation 
of organizational and technical measures to ensure protection of participant data. 
 
Participants’ personal data will be stored at the study site in encrypted electronic and/or paper 
form and will be password protected or secured in a locked room to ensure that only 
authorized study staff have access. The study site will implement appropriate technical and 
organizational measures to ensure that the personal data can be recovered in the event of 
disaster. In the event of a potential personal data breach, the study site will be responsible for 
determining whether a personal data breach has in fact occurred and, if so, providing breach 
notifications as required by law. 
 
To protect the rights and freedoms of participants with regard to the processing of personal 
data, participants will be assigned a single, participant-specific numerical code. Any 
participant records or data sets that are transferred to the sponsor will contain the numerical 
code; participant names will not be transferred. All other identifiable data transferred to the 
sponsor will be identified by this single, participant-specific code. The study site will 
maintain a confidential list of participants who participated in the study, linking each 
participant’s numerical code to his or her actual identity and medical record identification. In 
case of data transfer, the sponsor will protect the confidentiality of participants’ personal data 
consistent with the clinical study agreement and applicable privacy laws. 
 
10.1.5. Dissemination of Clinical Study Data

marketing authorization applications submitted via the centralized procedure since 
01 January 2015 and applications for line extensions and for new indications submitted via 
the centralized procedure since 01 July 2015. 
 
Data Sharing 
 
Pfizer provides researchers secure access to patient-level data or full CSRs for the purposes 
of “bona-fide scientific research” that contributes to the scientific understanding of the 
disease, target, or compound class. Pfizer will make available data from these trials 
24 months after study completion. Patient-level data will be anonymized in accordance with 
applicable privacy laws and regulations. CSRs will have personally identifiable information 
redacted. 
 
Data requests are considered from qualified researchers with the appropriate competencies to 
perform the proposed analyses. Research teams must include a biostatistician. Data will not 
be provided to applicants with significant conflicts of interest, including individuals 
requesting access for commercial/competitive or legal purposes. 
 
10.1.6. Data Quality Assurance 
All participant data relating to the study will be recorded on printed or electronic CRF unless 
transmitted to the sponsor or designee electronically (eg, laboratory data). The investigator is 
responsible for verifying that data entries are accurate and correct by physically or 
electronically signing the CRF. 
 
The investigator must maintain accurate documentation (source data) that supports the 
information entered in the CRF. 
 
The investigator must ensure that the CRFs are securely stored at the study site in encrypted 
electronic and/or paper form and are password protected or secured in a locked room to 
prevent access by unauthorized third parties. 
 
The investigator must permit study-related monitoring, audits, IRB/EC review, and 
regulatory agency inspections and provide direct access to source data documents. This 
verification may also occur after study completion. It is important that the investigator(s) and 

Glasdegib PF-04449913

their relevant personnel are available during the monitoring visits and possible audits or 
inspections and that sufficient time is devoted to the process. 
 
Monitoring details describing strategy (eg, risk-based initiatives in operations and quality 
such as risk management and mitigation strategies and analytical risk-based monitoring), 
methods, responsibilities, and requirements, including handling of noncompliance issues and 
monitoring techniques (central, remote, or on-site monitoring), are provided in the 
monitoring plan. 
 
The sponsor or designee is responsible for the data management of this study, including 
quality checking of the data. 
 
Study monitors will perform ongoing source data verification to confirm that data entered 
into the CRF by authorized site personnel are accurate, complete, and verifiable from source 
documents; that the safety and rights of participants are being protected; and that the study is 
being conducted in accordance with the currently approved protocol and any other study 
agreements, ICH GCP, and all applicable regulatory requirements. 
 
Records and documents, including signed ICDs, pertaining to the conduct of this study must 
be retained by the investigator for 15 years after study completion unless local regulations or 
institutional policies require a longer retention period. No records may be destroyed during 
the retention period without the written approval of the sponsor. No records may be 
transferred to another location or party without written notification to the sponsor. The 
investigator must ensure that the records continue to be stored securely for as long as they are 
maintained. 
 
When participant data are to be deleted, the investigator will ensure that all copies of such 
data are promptly and irrevocably deleted from all systems. 
 
The investigator(s) will notify the sponsor or its agents immediately of any regulatory 
inspection notification in relation to the study. Furthermore, the investigator will cooperate 
with the sponsor or its agents to prepare the investigator site for the inspection and will allow 
the sponsor or its agent, whenever feasible, to be present during the inspection. The 
investigator site and investigator will promptly resolve any discrepancies that are identified 
between the study data and the participant's medical records. The investigator will promptly 
provide copies of the inspection findings to the sponsor or its agent. Before response 
submission to the regulatory authorities, the investigator will provide the sponsor or its 
agents with an opportunity to review and comment on responses to any such findings. 
 
10.1.7. Source Documents 
Source documents provide evidence for the existence of the participant and substantiate the 
integrity of the data collected. Source documents are filed at the investigator site. 
 
Data reported on the CRF or entered in the eCRF that are from source documents must be 
consistent with the source documents or the discrepancies must be explained. The

investigator may need to request previous medical records or transfer records, depending on 
the study. Also, current medical records must be available. 
 
Definition of what constitutes source data can be found in the clinical monitoring plan. 
Description of the use of computerized system is documented in the Data Management Plan. 
10.1.8. Study and Site Start and Closure 
The study start date is the date on which the clinical study will be open for recruitment of 
participants. 
 
The first act of recruitment is the date of the first participant’s first visit and will be the study 
start date. 
 
The sponsor designee reserves the right to close the study site or terminate the study at any 
time for any reason at the sole discretion of the sponsor. Study sites will be closed upon study 
completion. A study site is considered closed when all required documents and study 
supplies have been collected and a study-site closure visit has been performed. 
 
The investigator may initiate study-site closure at any time upon notification to the sponsor if 
requested to do so by the responsible IRB/EC or if such termination is required to protect the 
health of study participants. 
 
Reasons for the early closure of a study site by the sponsor may include but are not limited 
to: 
• Failure of the investigator to comply with the protocol, the requirements of the 
IRB/EC or local health authorities, the sponsor's procedures, or GCP guidelines; 
• Discontinuation of further study intervention development. 
If the study is prematurely terminated or suspended, the sponsor shall promptly inform the 
investigators, the ECs/IRBs, the regulatory authorities, and any CRO(s) used in the study of 
the reason for termination or suspension, as specified by the applicable regulatory 
requirements. The investigator shall promptly inform the participant and should assure 
appropriate participant therapy and/or follow-up. 
 
Study termination is also provided for in the clinical study agreement. If there is any conflict 
between the contract and this protocol, the contract will control as to termination rights. 
 
10.1.9. Publication Policy 
The results of this study may be published or presented at scientific meetings by the 
investigator after publication of the overall study results or 1 year after the end of the study 
(or study termination), whichever comes first. 
 
The investigator agrees to refer to the primary publication in any subsequent publications 
such as secondary manuscripts, and submits all manuscripts or abstracts to the sponsor 
30 days before submission. This allows the sponsor to protect proprietary information and to 

Glasdegib PF-04449913 
Protocol B1371019 
Final Protocol Amendment 6, 02 February 2021 
PFIZER CONFIDENTIAL 
Page 52 
 
 
provide comments and the investigator will, on request, remove any previously undisclosed 
confidential information before disclosure, except for any study- or Pfizer 
intervention-related information necessary for the appropriate scientific presentation or 
understanding of the study results. 
 
For all publications relating to the study, the investigator will comply with recognized ethical 
standards concerning publications and authorship, including those established by the 
International Committee of Medical Journal Editors. 
 
The sponsor will comply with the requirements for publication of the overall study results 
covering all investigator sites. In accordance with standard editorial and ethical practice, the 
sponsor will support publication of multicenter studies only in their entirety and not as 
individual site data. In this case, a coordinating investigator will be designated by mutual 
agreement. 
 
Authorship of publications for the overall study results will be determined by mutual 
agreement and in line with International Committee of Medical Journal Editors authorship 
requirements. 
 
If publication is addressed in the clinical study agreement, the publication policy set out in 
this section will not apply. 
 
10.1.10. Sponsor’s Qualified Medical Personnel 
The contact information for the sponsor's appropriately qualified medical personnel for the 
study is documented in the study contact list located in the supporting study documentation. 
 
To facilitate access to appropriately qualified medical personnel on study-related medical 
questions or problems, participants are provided with a contact card at the time of informed 
consent. The contact card contains, at a minimum, protocol and study intervention identifiers, 
participant numbers, contact information for the investigator site, and contact details for a 
contact center in the event that the investigator site staff cannot be reached to provide advice 
on a medical question or problem originating from another healthcare professional not 
involved in the participant’s participation in the study. The contact number can also be used 
by investigator staff if they are seeking advice on medical questions or problems; however, it 
should be used only in the event that the established communication pathways between the 
investigator site and the study team are not available. It is therefore intended to augment, but 
not replace, the established communication pathways between the investigator site and the 
study team for advice on medical questions or problems that may arise during the study. The 
contact number is not intended for use by the participant directly, and if a participant calls 
that number, he or she will be directed back to the investigator site.

10.2. Appendix 2: Clinical Laboratory Tests 
 
Clinical laboratory tests will be conducted as per standard of care at the individual Study site. 
They will not be collected in the CRF. The laboratory tests described in the table below are 
recommended to determine participant dosing eligibility. Unscheduled clinical laboratory 
measurements may be obtained at any time during the study to assess any perceived safety 
issues. As per the investigator's evaluation, if any laboratory test is determined as an AE or 
SAE, this should be reported to the Sponsor as described in Appendix 3.

10.3. Appendix 3: Adverse Events: Definitions and Procedures for Recording, 
Evaluating, Follow-up, and Reporting 
10.3.1. Definition of AE 
 
AE Definition 
• An AE is any untoward medical occurrence in a patient or clinical study 
participant, temporally associated with the use of study intervention, whether or not 
considered related to the study intervention. 
• NOTE: An AE can therefore be any unfavorable and unintended sign (including an 
abnormal laboratory finding), symptom, or disease (new or exacerbated) 
temporally associated with the use of study intervention. 
 
 
Events Meeting the AE Definition 
• Any abnormal laboratory test results (hematology, clinical chemistry, or urinalysis) 
or other safety assessments (eg, ECG, radiological scans, vital sign measurements), 
including those that worsen from baseline, considered clinically significant in the 
medical and scientific judgment of the investigator Any abnormal laboratory test 
results that meet any of the conditions below must be recorded as an AE: 
• Is associated with accompanying symptoms. 
• Requires additional diagnostic testing or medical/surgical intervention. 
• Leads to a change in study dosing (outside of any protocol-specified dose 
adjustments) or discontinuation from the study, significant additional 
concomitant drug treatment, or other therapy. 
• Exacerbation of a chronic or intermittent preexisting condition including either an 
increase in frequency and/or intensity of the condition. 
• New conditions detected or diagnosed after study intervention administration even 
though it may have been present before the start of the study. 
• Signs, symptoms, or the clinical sequelae of a suspected drug-drug interaction. 
• Signs, symptoms, or the clinical sequelae of a suspected overdose of either study 
intervention or a concomitant medication. Overdose per se will not be reported as 
an AE/SAE unless it is an intentional overdose taken with possible 
suicidal/self-harming intent. Such overdoses should be reported regardless of 
sequelae. 
• The signs, symptoms, and/or clinical sequelae resulting from lack of efficacy will 
be reported as an AE or SAE if they fulfill the definition of an AE or SAE and meet 
the requirements as per Section 8.3.8.1. Also, “lack of efficacy” or “failure of 
expected pharmacological action” does not constitute an AE or SAE. 

Glasdegib PF-04449913 
Protocol B1371019 
Final Protocol Amendment 6, 02 February 2021 
PFIZER CONFIDENTIAL 
Page 55 
 
 
 
Events NOT Meeting the AE Definition 
• Any clinically significant abnormal laboratory findings or other abnormal safety 
assessments which are associated with the underlying disease, unless judged by the 
investigator to be more severe than expected for the participant’s condition. 
• The disease/disorder being studied or expected progression, signs, or symptoms of 
the disease/disorder being studied, unless more severe than expected for the 
participant’s condition. 
• Medical or surgical procedure (eg, endoscopy, appendectomy): the condition that 
leads to the procedure is the AE. 
• Situations in which an untoward medical occurrence did not occur (social and/or 
convenience admission to a hospital). 
• Anticipated day-to-day fluctuations of preexisting disease(s) or condition(s) present 
or detected at the start of the study that do not worsen. 
• Worsening of signs and symptoms of the malignancy under study should be 
recorded as AEs in the appropriate section of the CRF. Disease progression 
assessed by measurement of malignant lesions on radiographs or other methods 
should not be reported as AEs. 
 
 
10.3.2. Definition of SAE 
If an event is not an AE per definition above, then it cannot be an SAE even if serious 
conditions are met (eg, hospitalization for signs/symptoms of the disease under study, death 
due to progression of disease). 

Glasdegib PF-04449913 
Protocol B1371019 
Final Protocol Amendment 6, 02 February 2021 
PFIZER CONFIDENTIAL 
Page 56 
 
 
 
An SAE is defined as any untoward medical occurrence that, at any dose: 
a.  Results in death 
b. Is life-threatening 
The term “life-threatening” in the definition of “serious” refers to an event in which the 
participant 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. 
c.  Requires inpatient hospitalization or prolongation of existing hospitalization 
In general, hospitalization signifies that the participant has been detained (usually 
involving at least an overnight stay) at the hospital or emergency ward for observation 
and/or treatment that would not have been appropriate in the physician’s office or 
outpatient setting. Complications that occur during hospitalization are AEs. If a 
complication prolongs hospitalization or fulfills any other serious criteria, the event is 
serious. When in doubt as to whether “hospitalization” occurred or was necessary, the AE 
should be considered serious. 
Hospitalization for elective treatment of a preexisting condition that did not worsen from 
baseline is not considered an AE. 
d. Results in persistent disability/incapacity 
• The term disability means a substantial disruption of a person’s ability to conduct 
normal life functions. 
• This definition is not intended to include experiences of relatively minor medical 
significance such as uncomplicated headache, nausea, vomiting, diarrhea, 
influenza, and accidental trauma (eg, sprained ankle) which may interfere with or 
prevent everyday life functions but do not constitute a substantial disruption. 
e.  Is a congenital anomaly/birth defect 
f. Other situations: 
• Medical or scientific judgment should be exercised in deciding whether SAE 
reporting is appropriate in other situations such as important medical events that 
may not be immediately life-threatening or result in death or hospitalization but 
may jeopardize the participant or may require medical or surgical intervention to 
prevent one of the other outcomes listed in the above definition. These events 
should usually be considered serious. 
• 
Examples of such events include invasive or malignant cancers, intensive treatment 
in an emergency room or at home for allergic bronchospasm, blood dyscrasias or 
convulsions that do not result in hospitalization, or development of drug 
dependency or drug abuse. 

Glasdegib PF-04449913 
Protocol B1371019 
Final Protocol Amendment 6, 02 February 2021 
PFIZER CONFIDENTIAL 
Page 57 
 
 
 
• Progression of the malignancy under study (including signs and symptoms of 
progression) should not be reported as an SAE unless the outcome is fatal within 
the active collection period. Hospitalization due to signs and symptoms of disease 
progression should not be reported as an SAE. If the malignancy has a fatal 
outcome during the study or within the active collection period, then the event 
leading to death must be recorded as an AE on the CRF, and as an SAE with 
CTCAE Grade 5 (see the Assessment of Intensity section). 
• If the HIV-related disease has a fatal outcome during the study or within the active 
collection period, then the event leading to death must be recorded as an AE on the 
CRF and as an SAE. 
• 
Suspected transmission via a Pfizer product of an infectious agent, pathogenic or 
non-pathogenic, is considered serious. The event may be suspected from clinical 
symptoms or laboratory findings indicating an infection in a patient exposed to a 
Pfizer product. The terms “suspected transmission” and “transmission” are 
considered synonymous. These cases are considered unexpected and handled as 
serious expedited cases by pharmacovigilance personnel. Such cases are also 
considered for reporting as product defects, if appropriate. 
 
10.3.3. Recording/Reporting and Follow-up of AEs and/or SAEs 
 
AE and SAE Recording/Reporting 
The table below summarizes the requirements for recording AEs on the CRF and for 
reporting SAEs on the CT SAE Report Form to Pfizer Safety. These requirements are 
delineated for 3 types of events: (1) SAEs; (2) nonserious AEs and (3) exposure to the 
study intervention under study during pregnancy or breastfeeding, and occupational 
exposure. 
It should be noted that the CT SAE Report Form for reporting of SAE information is not 
the same as the AE page of the CRF. When the same data are collected, the forms must be 
completed in a consistent manner. AEs should be recorded using concise medical 
terminology and the same AE term should be used on both the CRF and the CT SAE 
Report Form for reporting of SAE information.

AEs/SAEs associated with 
occupational exposure. 
• When an AE/SAE occurs, it is the responsibility of the investigator to review all 
documentation (eg, hospital progress notes, laboratory reports, and diagnostic 
reports) related to the event. 
• The investigator will then record all relevant AE/SAE information in the CRF. 
• It is not acceptable for the investigator to send photocopies of the participant’s 
medical records to Pfizer Safety in lieu of completion of the CT SAE Report 
Form/AE/SAE CRF page. 
• There may be instances when copies of medical records for certain cases are 
requested by Pfizer Safety. In this case, all participant identifiers, with the 
exception of the participant number, will be redacted on the copies of the medical 
records before submission to Pfizer Safety. 
• The investigator will attempt to establish a diagnosis of the event based on signs, 
symptoms, and/or other clinical information. Whenever possible, the diagnosis (not 
the individual signs/symptoms) will be documented as the AE/SAE. 
Assessment of Intensity 
The investigator will make an assessment of intensity for each AE and SAE reported 
during the study based on NCI CTCAE Version 4.03: 
An event is defined as “serious” when it meets at least 1 of the predefined outcomes as 
described in the definition of an SAE, NOT when it is rated as severe.

Assessment of Causality 
• The investigator is obligated to assess the relationship between study intervention 
and each occurrence of each AE/SAE. 
• A “reasonable possibility” of a relationship conveys that there are facts, evidence, 
and/or arguments to suggest a causal relationship, rather than a relationship cannot 
be ruled out. 
• The investigator will use clinical judgment to determine the relationship. 
• Alternative causes, such as underlying disease(s), concomitant therapy, and other 
risk factors, as well as the temporal relationship of the event to study intervention 
administration, will be considered and investigated. 
• The investigator will also consult the IB and/or product information, for marketed 
products, in his/her assessment. 
• For each AE/SAE, the investigator must document in the medical notes that he/she 
has reviewed the AE/SAE and has provided an assessment of causality. 
• There may be situations in which an SAE has occurred and the investigator has 
minimal information to include in the initial report to the sponsor. However, it is 
very important that the investigator always make an assessment of causality for 
every event before the initial transmission of the SAE data to the sponsor. 
• The investigator may change his/her opinion of causality in light of follow-up 
information and send an SAE follow-up report with the updated causality 
assessment. 
• The causality assessment is one of the criteria used when determining regulatory 
reporting requirements. 
• If the investigator does not know whether or not the study intervention caused the 
event, then the event will be handled as “related to study intervention” for reporting 
purposes, as defined by the sponsor. In addition, if the investigator determines that 
an SAE is associated with study procedures, the investigator must record this 
causal relationship in the source documents and CRF, and report such an 
assessment in the dedicated section of the CT SAE Report Form and in accordance 
with the SAE reporting requirements.

Final Protocol Amendment 6, 02 February 2021 
PFIZER CONFIDENTIAL 
Page 60 
 
 
 
Follow-up of AEs and SAEs 
• The investigator is obligated to perform or arrange for the conduct of supplemental 
measurements and/or evaluations as medically indicated or as requested by the 
sponsor to elucidate the nature and/or causality of the AE or SAE as fully as 
possible. This may include additional laboratory tests or investigations, 
histopathological examinations, or consultation with other healthcare providers. 
• If a participant dies during participation in the study or during a recognized 
follow-up period, the investigator will provide Pfizer Safety with a copy of any 
postmortem findings including histopathology. 
• New or updated information will be recorded in the originally completed CRF. 
• The investigator will submit any updated SAE data to the sponsor within 24 hours 
of receipt of the information. 
10.3.4. Reporting of SAEs 
 
SAE Reporting to Pfizer Safety via CT SAE Report Form 
• Facsimile transmission of the CT SAE Report Form is the preferred method to 
transmit this information to Pfizer Safety. 
• In circumstances when the facsimile is not working, notification by telephone is 
acceptable with a copy of the CT SAE Report Form sent by overnight mail or 
courier service. 
• Initial notification via telephone does not replace the need for the investigator to 
complete and sign the CT SAE Report Form pages within the designated reporting 
time frames.

10.4. Appendix 4: Contraceptive Guidance 
10.4.1. Male Participant Reproductive Inclusion Criteria 
Male participants are eligible to participate if they agree to the following requirements during 
the intervention period and for at least 180 days after the last dose of study intervention, 
which corresponds to the time needed to eliminate reproductive safety risk of the study 
intervention(s) plus an additional 90 days (a spermatogenesis cycle): 
• Refrain from donating sperm. 
PLUS either: 
• Be abstinent from heterosexual intercourse as their preferred and usual lifestyle (abstinent 
on a long-term and persistent basis) and agree to remain abstinent. 
 
OR 
 
• Must agree to use contraception/barrier as detailed below. 
• Agree to use a male condom when engaging in any activity that allows for passage of 
ejaculate to another person. 
• Use of an additional highly effective contraceptive method with a failure rate of <1% per 
year as described below in Section 10.4.4 for a female partner of childbearing potential. 
 
10.4.2. Female Participant Reproductive Inclusion Criteria 
• A female participant is eligible to participate if she is not pregnant or breastfeeding, 
and at least 1 of the following conditions applies: 
 
• Is not a WOCBP (see definitions below in Section 10.4.3). 
• OR 
• Is a WOCBP and using a contraceptive method that is highly effective (with a 
failure rate of <1% per year), preferably with low user dependency, as described 
below during the intervention period and for at least 180 days after the last dose 
of study intervention, which corresponds to the time needed to eliminate any 
reproductive safety risk of the study intervention(s). The investigator should 
evaluate the effectiveness of the contraceptive method in relationship to the first 
dose of study intervention. 
 
• Is a WOCBP and using a contraceptive method that is highly effective (with a 
failure rate of <1% per year), with high user dependency, as described below 
during the intervention period and for at least 180 days after the last dose of study 
intervention, which corresponds to the time needed to eliminate any reproductive 
safety risk of the study intervention(s). In addition, a second effective method of 
contraception, as described below, must be used. The investigator should evaluate 

Glasdegib PF-04449913 
Protocol B1371019 
Final Protocol Amendment 6, 02 February 2021 
PFIZER CONFIDENTIAL 
Page 62 
 
 
the effectiveness of the contraceptive method in relationship to the first dose of 
study intervention. 
 
A WOCBP agrees not to donate eggs (ova, oocytes) for the purpose of reproduction during 
this period. The investigator should evaluate the effectiveness of the contraceptive method in 
relationship to the first dose of study intervention. 
 
The investigator is responsible for review of medical history, menstrual history, and recent 
sexual activity to decrease the risk for inclusion of a woman with an early undetected 
pregnancy. 
 
10.4.3. Woman of Childbearing Potential 
A woman is considered fertile following menarche and until becoming postmenopausal 
unless permanently sterile (see below). 
 
If fertility is unclear (eg, amenorrhea in adolescents or athletes) and a menstrual cycle cannot 
be confirmed before the first dose of study intervention, additional evaluation should be 
considered. 
 
Women in the following categories are not considered WOCBP: 
1. Premenarchal. 
2. Premenopausal female with 1 of the following: 
• Documented hysterectomy; 
• Documented bilateral salpingectomy; 
• Documented bilateral oophorectomy. 
For individuals with permanent infertility due to an alternate medical cause other than the 
above, (eg, mullerian agenesis, androgen insensitivity), investigator discretion should be 
applied to determining study entry. 
 
Note: Documentation for any of the above categories can come from the site personnel’s 
review of the participant’s medical records, medical examination, or medical history 
interview. The method of documentation should be recorded in the participant’s medical 
record for the study. 
 
3. Postmenopausal female: 
• A postmenopausal state is defined as no menses for 12 months without an alternative 
medical cause. In addition, 
 
• high FSH level in the postmenopausal range must be used to confirm a 
postmenopausal state in women under 60 years of age and not using hormonal 
contraception or HRT. 

Glasdegib PF-04449913 
Protocol B1371019 
Final Protocol Amendment 6, 02 February 2021 
PFIZER CONFIDENTIAL 
Page 63 
 
 
• Female on HRT and whose menopausal status is in doubt will be required to 
use one of the nonestrogen hormonal highly effective contraception methods 
if they wish to continue their HRT during the study. Otherwise, they must 
discontinue HRT to allow confirmation of postmenopausal status before study 
enrollment. 
 
10.4.4. Contraception Methods 
Contraceptive use by men or women should be consistent with local availability/regulations 
regarding the use of contraceptive methods for those participating in clinical trials. 
 
Highly Effective Methods That Have Low User Dependency 
 
1. Implantable progestogen-only hormone contraception associated with inhibition of 
ovulation. 
2. Intrauterine device. 
3. Intrauterine hormone-releasing system. 
4. Bilateral tubal occlusion. 
5. Vasectomized partner. 
• Vasectomized partner is a highly effective contraceptive method provided that the 
partner is the sole sexual partner of the WOCBP and the absence of sperm has 
been confirmed. If not, an additional highly effective method of contraception 
should be used. The spermatogenesis cycle is approximately 90 days. 
 
Highly Effective Methods That Are User Dependent 
 
1. Combined (estrogen- and progestogen-containing) hormonal contraception associated 
with inhibition of ovulation: 
• Oral; 
• Intravaginal; 
• Transdermal; 
• Injectable. 
2. Progestogen-only hormone contraception associated with inhibition of ovulation: 
• Oral; 
• Injectable. 
3. Sexual abstinence: 
• Sexual abstinence is considered a highly effective method only if defined as 
refraining from heterosexual intercourse during the entire period of risk associated 
with the study intervention. The reliability of sexual abstinence needs to be

evaluated in relation to the duration of the study and the preferred and usual 
lifestyle of the participant. 
 
One of the following effective barrier methods must be used in addition to the highly 
effective methods listed above that are user dependent: 
• Male or female condom with or without spermicide; 
• Cervical cap, diaphragm, or sponge with spermicide; 
• A combination of male condom with either cervical cap, diaphragm, or sponge 
with spermicide (double-barrier methods).

10.5. Appendix 5: Liver Safety: Suggested Actions and Follow-up Assessments 
Potential Cases of Drug-Induced Liver Injury 
Humans exposed to a drug who show no sign of liver injury (as determined by elevations in 
transaminases) are termed “tolerators,” while those who show transient liver injury, but adapt 
are termed “adaptors.” In some participants, transaminase elevations are a harbinger of a 
more serious potential outcome. These participants fail to adapt and therefore are 
"susceptible" to progressive and serious liver injury, commonly referred to as DILI. 
Participants who experience a transaminase elevation above 3 × ULN should be monitored 
more frequently to determine if they are an “adaptor” or are “susceptible.” 
 
LFTs are not required as a routine safety monitoring procedure in this study. However, 
should an investigator deem it necessary to assess LFTs because a participant presents with 
clinical signs/symptoms, such LFT results should be managed and followed as described 
below. 
 
In the majority of DILI cases, elevations in AST and/or ALT precede TBili elevations 
(>2 × ULN) by several days or weeks. The increase in TBili typically occurs while AST/ALT 
is/are still elevated above 3 × ULN (ie, AST/ALT and TBili values will be elevated within 
the same laboratory sample). In rare instances, by the time TBili elevations are detected, 
AST/ALT values might have decreased. This occurrence is still regarded as a potential DILI. 
Therefore, abnormal elevations in either AST OR ALT in addition to TBili that meet the 
criteria outlined below are considered potential DILI (assessed per Hy’s law criteria) cases 
and should always be considered important medical events, even before all other possible 
causes of liver injury have been excluded. 
 
The threshold of laboratory abnormalities for a potential DILI case depends on the 
participant’s individual baseline values and underlying conditions. Participants who present 
with the following laboratory abnormalities should be evaluated further as potential DILI 
(Hy’s law) cases to definitively determine the etiology of the abnormal laboratory values: 
 
• Participants with AST/ALT and TBili baseline values within the normal range who 
subsequently present with AST OR ALT values >3 × ULN AND a TBili value 
>2 × ULN with no evidence of hemolysis and an alkaline phosphatase value 
<2 × ULN or not available. 
• For participants with baseline AST OR ALT OR TBili values above the ULN, the 
following threshold values are used in the definition mentioned above, as needed, 
depending on which values are above the ULN at baseline: 
• Preexisting AST or ALT baseline values above the normal range: AST or ALT 
values >2 times the baseline values AND >3 × ULN; or >8 × ULN (whichever is 
smaller). 
• Preexisting values of TBili above the normal range: TBili level increased from 
baseline value by an amount of at least 1 × ULN or if the value reaches 
>3 × ULN (whichever is smaller).

Rises in AST/ALT and TBili separated by more than a few weeks should be assessed 
individually based on clinical judgment; any case where uncertainty remains as to whether it 
represents a potential Hy’s law case should be reviewed with the sponsor. 
 
The participant should return to the investigator site and be evaluated as soon as possible, 
preferably within 48 hours from awareness of the abnormal results. This evaluation should 
include laboratory tests, detailed history, and physical assessment. 
 
In addition to repeating measurements of AST and ALT and TBili for suspected cases of 
Hy’s law, additional laboratory tests should include albumin, CK, direct and indirect 
bilirubin, GGT, PT/INR, total bile acids, and alkaline phosphatase. Consideration should also 
be given to drawing a separate tube of clotted blood and an anticoagulated tube of blood for 
further testing, as needed, for further contemporaneous analyses at the time of the recognized 
initial abnormalities to determine etiology. A detailed history, including relevant information, 
such as review of ethanol, acetaminophen/paracetamol (either by itself or as a coformulated 
product in prescription or over-the-counter medications), recreational drug, supplement 
(herbal) use and consumption, family history, sexual history, travel history, history of contact 
with a jaundiced person, surgery, blood transfusion, history of liver or allergic disease, and 
potential occupational exposure to chemicals, should be collected. Further testing for acute 
hepatitis A, B, C, D, and E infection and liver imaging (eg, biliary tract) and collection of 
serum samples for acetaminophen/paracetamol drug and/or protein adduct levels may be 
warranted. 
 
All cases demonstrated on repeat testing as meeting the laboratory criteria of AST/ALT and 
TBili elevation defined above should be considered potential DILI (Hy’s law) cases if no 
other reason for the LFT abnormalities has yet been found. Such potential DILI (Hy’s law) 
cases are to be reported as SAEs, irrespective of availability of all the results of the 
investigations performed to determine etiology of the LFT abnormalities. 
 
A potential DILI (Hy’s law) case becomes a confirmed case only after all results of 
reasonable investigations have been received and have excluded an alternative etiology.

10.7. Appendix 7: Alternative Measures During Public Emergencies 
The alternative study measures described in this section are to be followed during public 
emergencies, including the COVID-19 pandemic. This appendix applies for the duration of 
the COVID-19 pandemic globally and will become effective for other public emergencies 
only upon written notification from Pfizer. 
 
Use of these alternative study measures are expected to cease upon the return of business as 
usual circumstances (including the lifting of any quarantines and travel bans/advisories). 
 
Details for entering the data in the CRF are described in the CRF Completion Guidelines. 
 
10.7.1. Telehealth Visits 
In the event that in-clinic study visits cannot be conducted, every effort should be made to 
follow up on the safety of study participants at scheduled visits per the Schedule of 
Activities or unscheduled visits. Telehealth visits may be used to continue to assess 
participant safety and collect data points. Telehealth includes the exchange of healthcare 
information and services via telecommunication technologies (eg, audio, video, video- 
conferencing software) remotely, allowing the participant and the investigator to 
communicate on aspects of clinical care, including medical advice, reminders, education, and 
safety monitoring. The following assessments must be performed during a telehealth visit: 
• Review and record study intervention(s), including compliance and missed doses. 
• Review and record any AEs and SAEs since the last contact. Refer Section 8.3 and 
Appendix 3. 
• Review and record any new concomitant medications or changes in concomitant 
medications since the last contact. 
• Review and record contraceptive method and results of pregnancy testing. Confirm 
that the participant is adhering to the contraception method(s) required in the 
protocol. Refer to Appendix 4 and Section 10.7.2.1 of this appendix regarding 
pregnancy tests. 
Study participants must be reminded to promptly notify site staff about any change in their 
health status. 
 
10.7.2. Alternative Facilities for Safety Assessments 
10.7.2.1. Laboratory Testing 
If a study participant is unable to visit the site for protocol-specified safety laboratory 
evaluations, testing may be conducted at a local laboratory if permitted by local regulations. 
The local laboratory may be a standalone institution or within a hospital. The following 
safety laboratory evaluations may be performed at a local laboratory: 
• Hematology 
• Chemistry 

Glasdegib PF-04449913 
Protocol B1371019 
Final Protocol Amendment 6, 02 February 2021 
PFIZER CONFIDENTIAL 
Page 70 
 
 
• Coagulation: PT/INR, PTT/aPTT 
• Urinalysis 
If a local laboratory is used, qualified study site personnel must order, receive, and review 
results. Site staff must collect the local laboratory reference ranges and certifications/ 
accreditations for filing at the site. Laboratory test results are to be provided to the site staff 
as soon as possible. The local laboratory reports should be filed in the participant’s source 
documents/medical records. 
 
If a participant requiring pregnancy testing cannot visit a local laboratory for pregnancy 
testing, a home urine pregnancy testing kit with a sensitivity of at least 25 IU/mL may be 
used by the participant to perform the test at home, if compliant with local regulatory 
requirements. The pregnancy test outcome should be documented in the participant’s source 
documents/medical records. Confirm that the participant is adhering to the contraception 
method(s) required in the protocol. 
 
10.7.3. Study Intervention 
If the safety of a trial participant is at risk because they cannot complete required evaluations 
or adhere to critical mitigation steps, then discontinuing that participant from study 
intervention must be considered. 
 
Study intervention may be shipped by courier to study participants if permitted by local 
regulations and in accordance with storage and transportation requirements for the study 
intervention. Pfizer does not permit the shipment of study intervention by mail. The tracking 
record of shipments and the chain of custody of study intervention must be kept in the 
participant’s source documents/medical records. 
 
The following is recommended for the administration of study intervention for participants 
who have active [confirmed (positive by regulatory authority-approved test) or presumed 
(test pending/clinical suspicion)] SARS-CoV2 infection: 
 
• For symptomatic participants with active SARS-CoV2 infection, study intervention 
should be delayed for at least 14 days from the start of symptoms. This delay is intended 
to allow the resolution of symptoms of SARS-CoV2 infection. 
• Prior to restarting treatment, the participant should be afebrile for 72 hours, and SARS- 
CoV2-related symptoms should have recovered to ≤ Grade 1 for a minimum of 72 hours. 
Notify the study team when treatment is restarted. 
• Continue to consider potential drug-drug interactions as described in Section 6.5 for any 
concomitant medication administered for treatment of SARS-CoV2 infection. 
 
10.7.4. Adverse Events and Serious Adverse Events 
If a participant has COVID-19 during the study, this should be reported as an AE or SAE and 
appropriate medical intervention provided. Study treatment should continue unless the

investigator/treating physician is concerned about the safety of the participant, in which case 
temporary or permanent discontinuation may be required. 
 
It is recommended that the investigator discuss temporary or permanent discontinuation of 
study intervention with the study medical monitor.

10.8. Appendix 8: France Contrat Unique 
1. GCP Training 
Before enrolling any participants, the investigator and any sub investigators will 
complete the Pfizer provided Good Clinical Practice training course (“Pfizer GCP 
Training”) or training deemed equivalent by Pfizer. Any investigators who later join 
the study will do the same before performing study related duties. For studies of 
applicable duration, the investigator and sub investigators will complete Pfizer GCP 
Training or equivalent every 3 years during the term of the study, or more often if 
there are significant changes to the ICH GCP guidelines or course materials. 
 
2. Study Intervention 
No participants or third-party payers will be charged for study intervention. 
 
3. Urgent Safety Measures 
In addition, the investigator will inform Pfizer immediately of any urgent safety 
measures taken by the investigator to protect the study participants against any 
immediate hazard, and of any serious breaches of this protocol or of ICH GCP that 
the investigator becomes aware of. 
 
4. Termination Rights 
Pfizer retains the right to discontinue development of PF-04449913 at any time. 
 
The investigator agrees to abide by the ethical principles set forth in the World Health 
Organization’s Guiding Principles for Human Cell, Tissue and Organ Transplantation 
(WHA63.22) (http://www.who.int/transplantation/en/) with regard to the study.

Summary and Rationale for Changes 
Endpoints: clarified response definition by 
defining CRi or better to include CR (including 
CRMRD-negative) or CRi for intensive chemotherapy 
participants, and CR (including CRMRD-negative), 
CRh, or CRi for non-intensive chemotherapy 
participants. CRh or better is only defined for 
non-intensive chemotherapy participants as CR 
(including CRMRD-negative) or CRh. Also updated 
Section 9.3 (and subsections) and Appendix 4 with 
these definitions. 
Schedule of Activities: 
• Clarified that bone marrow assessments for 
study assessments other than disease 
classification must be done after informed 
consent signed in footnotes, as specified in 
the Protocol Administrative Change Letter, 
dated 20 Dec 2017. 
• Added whole blood collection for 
immunophenotyping and molecular 
profiling on Day 1, prior to dosing study 
drug to provide a baseline sample to 
compare to future samples for MRD 
assessment. 
• Removed whole blood collection for 
pharmacogenomic analysis from intensive 
and non-intensive chemotherapy studies 
because pharmacogenomic analysis of drug 
metabolizing enzymes and transporters was 
no longer a priority for this study as it was 
unlikely to provide valuable information 
that would inform either safety or efficacy. 
Also removed Section in protocol defining 
this analysis. 
• Added additional times when bone marrow 
samples must be collected post 
consolidation for the Intensive Study so 
MRD status may be confirmed in a timely 
manner. 
• Table 3: blood chemistry deleted from 
follow-up visits; added in error.

Exclusion criteria #7: removed right bundle branch 
blocks as this is common and it should not be 
excluded. 
Section 4.3.1: Added a requirement for a backup 
contraception method in response to regulatory 
request. 
Section 5.4.1.3: removed subcutaneous route for 
cytarabine since this will not be an option. 
Removed term allogeneic because either 
autologous or allogeneic HSCT is allowed during 
the Intensive Chemotherapy Study per regulatory 
feedback. 
Section 5.8.1: re-organized CYP3A4/5 inducers so 
bullet appears under proper heading. 
Table 11 now specifies that glasdegib/placebo 
should be permanently discontinued for all cases 
of confirmed DILI/Hy’s Law and potential cases 
require glasdegib/placebo dose interruption and 
potential restarting. Added in response to 
regulatory request. 
Table 14 now includes required bicarbonate testing 
to determine dose reductions per azacitidine label, 
per regulatory request. Also clarified indication for 
U/A with microscopic evaluation and 24-hour 
urine protein. 
Sections 7.1.7: removed additional QTc 
monitoring requirements if a moderate/strong 
CYP3A4/5 inhibitor or TdP drug administered 
during study since additional monitoring was not 
required.

Secondary endpoints updated: 
• CR/CRh was added to duration of response 
assessment to match statistical analysis section. 
• CR/CRh was added to time to response 
assessment to match statistical analysis section. 
• Schedule of Activities (Intensive study): 
Pregnancy testing added for Day 1 of each 
Consolidation Cycle with single agent cytarabine 
and Day 1 of each cycle where single agent 
glasdegib/placebo administered to ensure 
appropriate safety monitoring. 
• Schedule of Activities (Intensive and 
Nonintensive studies): 
Immunophenotyping was removed because it is 
not required for any study analysis. 
Immunophenotyping was also removed from 
Sections 7.1 and 7.2.2 for consistency. 
X’s added to tables so tables now match footnotes 
indicating specified instances AEs and SAEs may 
be collected during the follow-up period. 
Table 2 and Table 4 now provide time windows 
for assessments allowing sites flexibility in 
obtaining assessments without jeopardizing data.

Summary and Rationale for Changes 
Other minor footnote clarifications to ensure 
consistency with tables. 
Inclusion Criterion #4: removed bullet indicating 
that the criterion does not apply to participants 
with bundle branch blocks and is otherwise 
asymptomatic. This conflicted with an exclusion 
criterion and was confusing. 
Exclusion Criterion #4: specified that a participant 
could not participate in other clinical studies 
involving other investigational drugs to clarify that 
this did not apply to glasdegib in this study. 
Section 5.4.1.2: Reduced the text describing the 
azacitidine supply to match information supplied 
for other chemotherapy drugs in this study. Edits 
added for clarity, instructing sites to follow local 
regulations. 
Section 5.5.5 updated per FDA request to provide 
more information regarding glasdegib/placebo 
dose modifications. 
• Corrected typographical error in 
Section 5.5.5.1 indicating that 
glasdegib or placebo does not need to 
be delayed or dose reduced for 
hematologic, study treatment related 
toxicity. 
• Specified dose escalations will not be 
allowed following glasdegib/placebo 
dose reductions. 
• Added Section 5.5.5.2 for dosing 
interruptions for glasdegib/placebo 
non-hematological toxicities. 
• Section 5.8.1: corrected a typographical error, 
removing word permitted. 
Section 7.1.3: Added text specifying that 
assessment of acute GVHD will be graded by 
standard criteria based on the Consensus 
conference on acute GVHD grading and 
assessment of chronic GVHD will be assessed 
based on the NIH criteria with associated

references. Grading and Staging for acute GVHD 
is summarized in Appendix 15. 
• Section 7.1.4: Clarified that laboratory tests 
only need to be obtained during screening, and 
there is no need to repeat these tests on Day 1 
if performed within 3 days prior to 
randomization. 
• Section 7.1.7: specified type of ECGs (supine) 
for clarity. 
• Section 7.4.3 updated per FDA request: 
• Changed PGIS from a 7 point scale to a 4 point 
scale. The FDA recommended that Pfizer 
revise the PGIS to 4 response options (eg, 
absent (no symptoms), mild, moderate, and 
severe) so patients can easily distinguish 
severity. 
• Section 9.2.5: updated for clarity; now 
specifies Intensive and Nonintensive studies. 
• Section 9.3.2: updated per FDA request, 
specifying type of analysis required for fatigue 
and to correct minor errors. 
This section also includes an update to correct a 
typographical error: Method 1 sensitivity analysis 
for EFS must include CRi and Method 4 must not 
include CRi for the Intensive Study. 
For the Nonintensive study, Method 2 for the EFS 
definition now specifies CR or CRi will be 
evaluated following up to 6 cycles of therapy. 
Now specifies the Brookmeyer and Crowley 
method will be used to evaluate EFS for clarity. 
PK Parameters now specify Ctrough will be reported 
for glasdegib metabolites, if relevant. Though 
there is no activity anticipated for the N-desmethyl 
metabolite (M3) that is <10% in circulation; 
possible metabolite measurement is added, if 
applicable as a conservative approach.

indicated. Other minor changes were added for 
clarity. 
Schedule of Activities for the Intensive and 
Non-intensive Studies and applied throughout 
protocol: 
• For bone marrow assessments, bone marrow 
aspirates are required; however, we now added 
preference for bone marrow biopsies in 
addition to aspirates. In the event of an 
inadequate aspirate, a bone marrow biopsy is 
required. 
• Baseline genetics edits made for clarification 
that known genetics at the time of 
randomization will be used to stratify 
participants. 
• Red blood cell and platelet transfusion history 
required 8 and not 24 weeks prior to 
randomization for the nonintensive study only. 
• Added windows for follow-up assessments.

Inclusion Criterion 5: removed one single dose of 
Ara-C of up to 2 grams for control of blasts 
counts. 
Exclusion Criterion 10: clarified that dose 
equivalent of ≥550 mg/m2 of daunorubicin is a 
criterion for the Intensive Chemotherapy study 
only. 
Dose Modifications (Section 5.5.5): clarified 
glasdegib or placebo does not be delayed or dose 
reduced for Grade 3/Grade 4 nonhematologic, 
study treatment related toxicity and should be 
permanently discontinued if interruptions are for 
more than 28 consecutive days. 
Concurrent administration of herbal preparations 
prohibited (Section 5.8.1), added as a clarification 
since it is already an exclusion criterion.
