2.3. Study Design
This study is a randomized, investigator- and participant-blind, sponsor-open, 
placebo-controlled, FIH, single ascending dose, 4-period, crossover, interleaving design 
study of PF-07853578 orally administered to healthy adult participants. Approximately 
24 healthy adult participants (up to 3 cohorts of approximately 8 participants each) will be 
enrolled in this study. The optional third cohort will only be used if the objectives of the study 
are not fulfilled in Cohort 1 and Cohort 2. Each participant is planned to undergo 
4 treatment periods receiving up to 4 doses of PF-07853578 and up to 2 doses of placebo. In 
each period, participants will be randomized to either PF-07853578 or placebo in a ratio of 
6:2. A diagram of the study design is shown in Figure 1.
Precautionary sentinel dosing will be used in any period evaluating escalating doses of 
PF-07853578. Two participants (1 receiving PF-07853578 and 1 receiving placebo) within a 
period will be dosed initially before the remaining participants of that period are dosed. 
Safety and tolerability data through at least 24 hours post-dose for the sentinel participants 
will be reviewed prior to dosing the remaining participants of that period. Sentinel dosing 
may be omitted when repeating a dose level or administering a lower dose level than 
previously evaluated.
Figure 1. Study Design: Interleaving, Placebo-Controlled, 4-Period, Crossover Design
Screening activities will be completed over the 28 days prior to randomization in Period 1. In 
each period, participants will be admitted to the CRU on Day -1 and will remain in the CRU 
through at least the 72-hour assessments on Day 4. Participants may remain in the CRU 
after completion of Day 4 activities at the discretion of the investigator or if safety, 
tolerability, or PK data dictate the need to prolong confinement in the CRU. Participants will

receive a single oral dose of PF-07853578 or placebo on Day 1 of each period. Dose levels 
will be escalated to bracket the expected clinical dose range, but the projected exposures will 
not exceed the predefined human exposure limits. Within an individual participant, there will 
be a washout interval of at least 10 days between doses. The total duration of participation 
from the screening visit to the telephone follow-up contact will be approximately 17 weeks 
for each participant. Participants will return for an on-site follow-up visit 7-10 days after the 
final dose of study intervention. The follow-up contact may occur via telephone contact and 
must occur 28-35 days after administration of the final dose of study intervention. 
Dosing will occur in the fasted state for all periods, except if an optional exploratory 
assessment of the effect of food on PF-07853578 PK is conducted. If the food effect is 
evaluated, it is anticipated that study intervention will be administered in the fed state in the 
last period of Cohort 2 or Cohort 3 at a dose level that was previously administered fasted 
within the same cohort. However, study intervention may be administered in the fed state 
during any of the study periods/cohorts if thought necessary to achieve study objectives. The 
actual dose level will be selected based on emerging safety, tolerability, and PK data but will 
be expected to achieve approximate projected therapeutic exposures. 
If evaluated, the IDS oral solution of PF-07853578 is anticipated to be assessed in the last 
period of Cohort 2 or Cohort 3 at a dose level that was previously administered as a 
suspension within the same cohort. However, the IDS oral solution may be administered 
during any of the study periods/cohorts if thought necessary to achieve study objectives.
3. ENDPOINTS AND BASELINE VARIABLES: DEFINITIONS AND 
CONVENTIONS
3.1. Primary Endpoint(s)
Primary endpoints include assessment of adverse events (AEs) and treatment-emergent 
adverse events (TEAEs), clinical safety laboratory abnormalities, vital signs, ECG 
parameters, cardiac monitoring, and physical and neurological examinations during the entire 
study, by period. 
Any events occurring following start of study intervention (ie, treatment with PF-07853578 
or placebo) will be counted as treatment emergent. 
Events that occur in a non-treatment period (eg, washout or follow-up) will be counted as 
treatment emergent and attributed to the most recent treatment taken.
A 3-tier approach for summarizing adverse events (AEs) will not be used due to the low 
number of participants planned to be recruited. 
The following data are considered in standard safety summaries (see protocol for collection 
days and list of parameters):

adverse events,

laboratory data (except data from screening visit),

vital signs data,


ECG results,

cardiac monitoring, 

physical examinations, 

neurological examinations.
3.1.1. Adverse Events
An AE is considered a TEAE if the event started during the effective duration of treatment. All 
events that start on or after the first dose of study intervention, but before the end of the study 
will be flagged as TEAEs. The algorithm will not consider any events that started prior to the 
first dose date.
3.1.2. Laboratory Data
Safety laboratory tests will be performed as described in the protocol.
The investigator must review the laboratory report, document this review, and record any 
clinically significant changes occurring during the study in the AE section of the CRF. 
Clinically significant abnormal laboratory test findings are those that are not associated with 
the underlying disease, unless judged by the investigator to be more severe than expected for 
the participant’s condition.
Baseline will be the last pre-dose measurement in each study period.
To determine if there are any clinically significant laboratory abnormalities, the hematological, 
clinical chemistry (serum) and urinalysis safety tests will be assessed against the criteria 
specified in the sponsor reporting standards. The assessment will take into account whether 
each participant’s baseline test result is within or outside the laboratory reference range for the 
particular laboratory parameter.
3.1.3. Vital Signs
Single supine blood pressure and pulse rate measurements will be taken at screening, follow-
up visit and at early termination (if applicable). Triplicate supine measurements will be taken 
at all other times as detailed in the Schedule of Activities (SoA) in the protocol. The average 
of the triplicate measurements will be calculated prior to analyzing the data. Respiratory rate 
will be measured at each timepoint specified in the protocol.
Baseline for these measures will be defined as the last pre-dose measurement in each study 
period.
The following endpoints will be determined:

Change from baseline (CFB) in systolic and diastolic BP, pulse rate and respiratory rate

The minimum and maximum post-dose systolic and diastolic BP, pulse rate and 
respiratory rate

The maximum increase and decrease from baseline over all measurements taken post-
dose for systolic and diastolic BP, pulse rate and respiratory rate values

The maximum decrease and increase from baseline over all measurements taken post-dose will 
be calculated for supine systolic and diastolic blood pressures and pulse rates. The maximum 
increase from baseline will be calculated by selecting the maximum change from baseline over 
the respective period, except in the case where a participant does not show an increase. In such 
an instance, the minimum decrease should be taken. Similarly, the maximum decrease from 
baseline will be determined by selecting the minimum value of the change from baseline. In 
cases where a participant does not show a decrease, the minimum increase should be taken.
3.1.4. Electrocardiograms
A single 12-lead ECG will be obtained on all participants at screening, follow-up visit and at 
early termination (if applicable). 12-lead ECGs will be recorded in triplicate at all other times 
as detailed in the SoA in the protocol. The average of the triplicate readings collected at each 
assessment time will be calculated for each ECG parameter.
The average of the triplicate ECG measurements over the 3 pre-dose measurement times (-1H, 
-0.5H, and pre-dose 0H; total of 9 ECG measurements) collected before morning dose 
administration on Day 1 will serve as each participant’s baseline value in each study period.
ECG endpoints include heart rate, QT interval, PR interval and QTcF and QRS complex. If 
not supplied QTcF will be derived using Fridericia’s heart rate correction formula:
QTcF = QT / (RR)1/3 where RR = 60/HR (if RR not provided).
The following endpoints will be determined:

Change from baseline in QT, QTcF, PR, QRS interval and heart rate

The maximum post-dose QTcF, heart rate, PR and QRS interval

The maximum increase from baseline over all measurements taken post-dose for QTcF, 
heart rate, PR and QRS values
The maximum increase from baseline will be calculated by selecting the maximum change 
from baseline over the respective period, except in the case where a participant does not show 
an increase.  In such an instance, the minimum decrease should be taken.
3.1.5. Continuous Cardiac Monitoring
Continuous cardiac monitoring will be performed using telemetry as outlined in the protocol.
All abnormal rhythms will be recorded and reviewed by the study physician for the presence 
of rhythms of potential clinical concern. The time, duration, and description of the clinically 
significant event will be recorded in the CRF.
Events deemed of clinical concern will be recorded as AEs and will be summarized as part of 
the standard AE outputs.

3.1.6. Neurological examinations 
Neurological examinations may be conducted by a physician, trained physician's assistant, 
or nurse practitioner as acceptable according to local regulation at the nominal time points 
specified in the SoA. The neurological exam will consist of assessment of higher cortical 
function, the cranial nerves, motor function, deep tendon reflexes, sensory exam, and
coordination and gait. Additional neurological examinations that are outside of SoA (eg, to
evaluate an AE) may be conducted at the discretion of investigator. All neurological exams
should be done to the extent needed to assess the participant for any potential changes in
neurological status, as determined by the investigator (or designee). Changes in the timing 
or addition of timepoints for the neurological examinations may occur based on emerging 
data.
Any untoward neurological examination findings that are identified during the active collection 
period will be captured as AEs or SAEs, if those findings meet the definition of an AE or SAE, 
and will be summarized as part of the standard AE outputs.
3.1.7. Physical Examinations
Complete physical examinations will be conducted at screening or upon admission for a 
participant’s first period in the study. At all other timepoints, a brief physical exam may be 
performed for the findings during a previous exam or new/open AEs at the investigators 
discretion. Height and weight will only be measured at the screening visit.
Physical examination findings collected during the study will be considered source record and 
will not be required to be reported, unless otherwise noted. 
Any untoward physical examination findings that are identified during the active collection 
period will be captured as AEs or SAEs, if those findings meet the definition of an AE or SAE, 
and will be summarized as part of the standard AE outputs.
3.2. Secondary Endpoint(s)
Blood samples for PK analysis of PF-07853578 will be taken according to the SoA in the 
protocol.
The plasma PK parameters for PF-07853578, following oral dose administration, will be 
derived from the plasma concentration-time profiles using standard noncompartmental 
methods as detailed in Table 2, as data permit. Table 2 shows the analysis scale and method 
for each parameter.
In all cases, actual PK sampling times will be used in the derivation of PK parameters. If actual 
PK sampling times are not available, nominal PK sampling times will be used in the derivation 
of PK parameters.
The following plasma PK parameters as described in Table 2 will be determined:

5. GENERAL METHODOLOGY AND CONVENTIONS
5.1. Hypotheses and Decision Rules
There is no statistical hypothesis testing planned for this study, and no statistical decision 
rules will be applied.
5.2. General Methods
Unless otherwise stated, all summaries and plots will be presented by dose and treatment as 
applicable. Each formulation of PF-07853578 administered during the study and fasting status 
will be considered as separate treatments.
Unless otherwise stated the summary tables and/or statistical analyses will only include a single 
pooled placebo group across all included cohorts. Placebo will be pooled from all dose 
escalation periods but not for the fed period (if conducted) and for IDS oral solution period (if 
conducted).
5.2.1. Analyses for Continuous Endpoints
Unless otherwise stated, continuous variables will be presented using summary statistics: 
number of observations, arithmetic mean, standard deviation, median, minimum and 
maximum values.
5.2.2. Analyses for Categorical Endpoints
Categorical variables will be presented using summary statistics: number of observations and 
percentages.
5.2.3. Mixed Effect Model
A mixed effects model with treatment as a fixed effect and participant as a random effect will 
be used for analysis of the:

Effect of food on PF-07853578 PK

PF-07853578 PK of IDS oral solution relative to the oral suspension formulation.
Estimates of the adjusted (least squares) mean differences (Test-reference) and corresponding 
90% confidence intervals will be obtained from the model. The adjusted mean differences 
and 90% confidence intervals for the differences will be exponentiated to provide estimates 
of the ratio of adjusted geometric means (Test/Reference) and 90% confidence intervals for 
the ratios.
The mixed effects model will be implemented using SAS Proc Mixed, with REML 
estimation method and the Kenward-Roger degrees of freedom algorithm.
Residuals from the models will be examined for normality and the presence of outliers via 
visual inspection of plots of residuals vs predicted values and normal probability plots of 
residuals, but these will not be included in the clinical study report. If there are major

deviations from normality or outliers (where studentized [conditional] residuals are greater 
than 3 or less than -3), then the effect of these on the conclusions may be investigated 
through alternative transformations and/or analyses excluding outliers. Justification for any 
alternative to the planned analysis will be given in the report of the study if applicable.
Example code is shown in Appendix 1.
5.3. Methods to Manage Missing Data
For the analysis of safety endpoints, the sponsor data standard rules for imputation will be 
applied.
In all PK data presentations (except listings), concentrations below the limit of quantification 
(BLQ) will be set to zero. In listings BLQ values will be reported as “<LLOQ”, where LLOQ 
will be replaced with the value for the LLOQ.
In PK summary tables and plots of median profiles, statistics will be calculated having set 
concentrations to missing if one of the following cases is true:
1. A concentration has been collected as ND (ie, not done) or NS (ie,no sample),
2. A deviation in sampling time is of sufficient concern or a concentration has been 
flagged anomalous by the pharmacokineticist/statistician.
Note that summary statistics will not be presented at a particular time point if more than 50% 
of the data are missing.
Participants who experience events that may affect their PK profile (e.g., lack of compliance 
with dosing or vomiting) may be excluded from the PK analysis. At the discretion of the 
pharmacokineticist, a concentration value may also be excluded if the deviation in sampling 
time is of sufficient concern or if the concentration is anomalous for any other reason.
A full list of protocol deviations will be compiled and reviewed to identify major and minor 
deviations prior to database closure.
5.3.1. Plasma Pharmacokinetic Parameters
Actual PK sampling times will be used in the derivation of plasma PK parameters.
If a PK parameter cannot be derived from a participant’s concentration data, the parameter 
will be coded as NC (i.e., not calculated). (Note that NC values will not be generated beyond 
the day that a participant discontinues.)
In summary tables, statistics will be calculated by setting NC values to missing; and statistics 
will be presented for a particular treatment group/analyte with ≥3 evaluable measurements. 
For statistical analyses (i.e., mixed effects model), PK parameters coded as NC will also be 
set to missing; and analyses will not be performed for a particular parameter if more than 
50% of the data are NC.

If an individual participant has a known biased estimate of a plasma PK parameter (due, for 
example, to an unexpected event such as vomiting before all the compound is adequately 
absorbed in the body), this will be footnoted in summary tables and may not be included in 
the calculation of summary statistics or statistical analyses.
6. ANALYSES AND SUMMARIES
For all presentations, study day will refer to the day within a particular treatment period, 
unless otherwise specified.
6.1. Primary Endpoint(s)
6.1.1. Adverse Events
AEs will be summarized by dose and treatment (if applicable) and overall and in accordance 
with sponsor reporting standards using the safety population defined in Section 4.
Incidence and severity of TEAE tables will additionally be produced (‘All causality’ and 
‘Treatment related,’ separately) to summarize the total number of adverse events by preferred 
term, which will be reported by dose and treatment (if applicable) and overall, in accordance with 
sponsor reporting standards using the safety analysis set defined in Section 4.
The AEs will be presented sorted in descending frequency based on the overall number of 
AEs (by preferred term or system order class as appropriate) across treatments.
6.1.2. Laboratory Data
Safety laboratory data will be listed and summarized by dose and treatment (if applicable) 
and overall, in accordance with the sponsor reporting standards using the safety population 
defined in Section 4 . 
In summary and listing tables, laboratory abnormalities occurring pre-dose on Day -1 for 
each period starting with Period 2, will be attributed to the treatment from the previous 
period (eg, for Cohort 1, an occurrence pre-dose at Period 2 Day -1 will be attributed to the 
Period 1 dose). 
6.1.3. Vital Signs
Absolute values and changes from baseline (as defined in Section 4) in supine systolic and 
diastolic blood pressure, respiratory rate, and pulse rate will be listed, and summarized by 
dose and treatment (if applicable) and time point, according to sponsor reporting standards 
using the safety population defined in Section 4.
Mean absolute values and mean changes from baseline for systolic and diastolic blood 
pressure, respiratory rate, and pulse rate will be plotted against time point. On each plot,
there will be 1 line for each treatment with all treatments on the same plot. Corresponding 
individual plots of changes from baseline will also be produced for each treatment.

Maximum and minimum absolute values and changes from baseline (as defined in Section 
3.1) for supine vital signs will also be summarized descriptively by dose and treatment (if 
applicable) using categories as defined in Appendix 2. 
Numbers and percentages of participants meeting the categorical criteria will be provided. 
All planned and unplanned post dose time points will be counted in these categorical 
summaries. All values meeting the criteria of potential clinical concern will be listed.
Values meeting the categorical criteria occurring pre-dose on Day 1 for each period starting 
with Period 2, will be attributed to the treatment from the previous period (e.g., for cohort 1, 
an occurrence pre-dose at Period 2 Day 1 will be attributed to the Period 1 dose). 
Data collected at screening that are used for inclusion/exclusion criteria, will be considered 
source data, and will not be required to be reported, unless otherwise noted. 
6.1.4. Electrocardiograms
Absolute values and changes from baseline in QT, heart rate, QTcF, PR and QRS will be 
summarized by dose and treatment (if applicable) and timepoint using sponsor reporting 
standards, using the safety analysis set defined in Section 4. Baseline is as defined in Section 
3.1.4 .
Mean changes from baseline in QT, heart rate and QTcF will be plotted against time post-dose. 
On each plot there will be one line for each treatment. Corresponding individual plots of 
changes from baseline will also be produced for each treatment.
Changes from baseline in QTcF will also be plotted separately against drug concentrations of 
PF-07853578. This will be a scatter plot for all observations where QTcF and drug 
concentration are recorded. Placebo data will also be included (with drug concentration set to 
zero). Different symbols will be used for each treatment.
Maximum increase from baseline for QTcF, heart rate, PR and QRS values will be summarized 
by dose and treatment (if applicable) according to sponsor reporting standards. 
ECG endpoints and changes from baseline (QTcF, PR and QRS) will also be summarized 
descriptively by dose and treatment (if applicable) using categories as defined in Appendix 2 . 
Numbers and percentages of participants meeting the categorical criteria will be provided. All 
planned and unplanned postdose time points will be counted in these categorical summaries.  
Values meeting the categorical criteria occurring pre-dose on Day 1 for each period starting 
with Period 2, will be attributed to the treatment from the previous period (e.g., for cohort 1, 
an occurrence pre-dose at Period 2 Day 1 will be attributed to the Period 1 dose).
Listings of participants with any single post-dose value >500msec will also be produced for 
QTcF.
Data collected at screening that are used for inclusion/exclusion criteria, will be considered 
source data, and will not be required to be reported, unless otherwise noted.

No interim analysis will be conducted for this study. 
However, preliminary draft safety and PK data will be reviewed after each study period. This 
is a sponsor-open study, with the investigator and participant blinded to study treatment. A 
limited number of Pfizer personnel (eg, PK assay specialist, medical monitor, clinical lead, 
study clinician, statistician, clinical programmer, and clinical pharmacology lead) will be 
unblinded to treatments in order to permit real-time interpretation of the safety and 
pharmacokinetic data, and to provide information necessary for dose escalation decisions and
