- Screening supine BP ≥140 mm Hg (systolic) or ≥90 mm Hg (diastolic), following at least 5 minutes of supine rest. If BP is ≥140 mm Hg (systolic) or ≥90 mm Hg (diastolic), the BP should be repeated 2 more times and the average of the 3 BP values should be used to determine the participant's eligibility.
- Baseline 12 lead electrocardiogram (ECG) that demonstrates clinically relevant abnormalities that may affect participant safety or interpretation of study results (eg, baseline corrected QT (QTc) interval >450 msec, complete left bundle branch block [LBBB], signs of an acute or indeterminate age myocardial infarction, ST T interval changes suggestive of myocardial ischemia, second or third degree atrioventricular [AV] block, or serious bradyarrhythmias or tachyarrhythmias). If the baseline uncorrected QT interval is >450 msec, this interval should be rate corrected using the Fridericia method and the resulting QTcF should be used for decision making and reporting. If QTc exceeds 450 msec, or QRS exceeds 120 msec, the ECG should be repeated 2 more times and the average of the 3 QTc or QRS values should be used to determine the participant's eligibility. Computer interpreted ECGs should be overread by a physician experienced in reading ECGs before excluding participants.
- Participants with ANY of the following abnormalities in clinical laboratory tests at screening, as assessed by the study specific laboratory and confirmed by a single repeat test, if deemed necessary:
- Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) level ≥1.5 × upper limit of normal (ULN);
- Total bilirubin level ≥1.5 × ULN; participants with a history of Gilbert's syndrome may have direct bilirubin measured and would be eligible for this study provided the direct bilirubin level is ≤ ULN.
- Other Exclusions:
- History of alcohol abuse or binge drinking and/or any other illicit drug use or dependence within 6 months of Screening. Binge drinking is defined as a pattern of 5 (male) and 4 (female) or more alcoholic drinks in about 2 hours. As a general rule, alcohol intake should not exceed 14 units per week (1 unit = 8 ounces (240 mL) beer, 1 ounce (30 mL) of 40% spirit or 3 ounces (90 mL) of wine).
- Use of tobacco/nicotine containing products more than 5 cigarettes/day.
- Blood donation (excluding plasma donations) of approximately 1 pint (500 mL) or more within 60 days prior to dosing.
- History of serious adverse reactions or hypersensitivity to any topical drug; or known allergy to any of the test product(s) or any components in the test product(s) or history of hypersensitivity; or allergic reactions to any of the study preparations as described in the PF-07295324 IB and PF-07259955 IB.
- Not willing to refrain from shaving, the use of depilatories or other hair-removal activities, antiperspirants, lotions, skin creams, fragrances or perfumes, or body oils (eg, baby oil; coconut oil), use of hair products, hair gels, and hair oil in the treatment areas for 48 hours prior to admission to the CRU and for the duration of the stay in the CRU.

Time frame: Baseline up to the end of follow up (ie, up to 44 days)
An AE was any untoward medical occurrence in a clinical investigation where participant administered a product; the event did not need to have a causal relationship with the treatment. A SAE was any untoward medical occurrence at any dose that resulted in death; was life threatening; required inpatient hospitalization or prolongation of existing hospitalization; resulted in persistent or significant disability/incapacity; resulted in congenital anomaly/birth defect. AEs included both SAEs and non-serious AEs. Treatment-related AEs and SAEs were determined by the investigator.
Number of Participants With Laboratory Abnormalities
Time frame: At screening, admission (Day -1), on Days 5, 7, 10, at discharge (Day 12), and at early termination if applicable
Hematology parameters included hemoglobin, hematocrit, red blood cell count, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, platelet and white blood cell count, total neutrophils, eosinophils, monocytes, basophils, reticulocytes, and lymphocytes. Chemistry parameters included blood urea nitrogen, creatinine, glucose (fasting), calcium, sodium, potassium, chloride, total bicarbonate, aspartate aminotransferase, alanine aminotransferase, total bilirubin, alkaline phosphatase, uric acid, albumin, total protein. Urine parameters included pH, glucose, protein, blood, ketones, nitrites, leukocyte esterase, urobilinogen, urine bilirubin, microscopy. Only those categories in which at least 1 participant had abnormal data were reported.
Number of Participants With Vital Signs Abnormalities
Time frame: At screening, on Days 1, 2, 5, 7, 10, 11, at discharge (Day 12), and at early termination if applicable
Criteria for abnormality in vital signs: supine pulse rate <40 beats per minute (bpm) or >120 bpm; supine diastolic blood pressure (DBP) <50 mmHg, maximum increase or decrease from baseline of >=20 mmHg; supine systolic blood pressure (SBP) <90 mmHg, maximum increase or decrease from baseline of >=30 mmHg. Baseline was defined as the last measurement prior to the first dosing. Vital sign abnormalities reported for at least 1 participant are presented here.
Number of Participants With Clinically Significant Abnormalities in Electrocardiogram (ECG) Findings
Time frame: At screening, on Days 1, 2, 5, 7, 10, 11, at discharge (Day 12), and at early termination if applicable
ECG abnormalities criteria included: 1) maximum QTc interval adjusted according Fridericia formula (QTcF) (msec): 450<= QTcF <480, 480<= QTcF <500, and QTcF >=500; QTcF maximum increase from baseline (msec): 30<= change <60, and change >=60; 2) maximum PR interval (msec): >=300; PR increase from baseline (msec): baseline >200 with 25% increase at maximum, baseline <=200 with 50% increase at maximum; 3) maximum QRS (msec): >=140; QRS increase from baseline (msec) >=50%. Baseline was defined as the average of the last triplicate measurement prior to the first dosing. ECG abnormalities reported for at least 1 participant are presented here.
Skin Irritation Assessments Using Draize Scoring
Time frame: Screening up to Day 12 or early termination if applicable
Application site toleration was assessed by Draize scoring. Draize scores were defined as: 0 = No reaction visible, 1 = Trace reaction - barely perceptible pinkness, 2 = Mild reaction - readily visible pinkness, 3 = Moderate reaction - definite redness, 4 = Strong to severe reaction - very intense redness. Participants with at least 1 instance of Draize score >0 were listed.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing PF-07295324 and PF-07259955 in people with Healthy, run by Pfizer at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 8 inclusion and 40 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 14 Nov 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 14 Nov 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs) (time frame: Baseline up to the end of follow up (ie, up to 44 days)). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Nov 2024.
