Brief summary

This is the first time PF-07242813 will be given to humans. The purpose of the study is to evaluate the safety, tolerability, and pharmacokinetics of escalating single and repeat doses of PF-07242813 in healthy participants and in participants with moderate to severe atopic dermatitis. An additional goal is to assess the pharmacodynamics of PF-07242813 in participants with moderate to severe AD, including potential effects on clinical signs and symptoms.

Outcome results

Primary

Part 1: MAD Cohorts: Number of Participants With Clinically Significant Findings in ECG

Twelve lead ECGs were obtained using an ECG machine that automatically calculated the heart rate and measured PR interval, QT interval, QTc intervals and QRS complex. ECGs were performed after the participant had rested quietly for at least 10 minutes in a supine position. Clinically significant findings were determined by the investigator.

Time frame: From pre-dose on Day 1 up to Day 99

Population: Safety analysis set consisted of all participants randomly assigned to study intervention and who received at least one dose of study intervention.

Part 1: MAD Cohorts: Number of Participants With Clinically Significant Findings in Vital Signs

Vital signs included blood pressure, pulse rate, respiratory rate and temperature. Temperature was measured by oral, tympanic, or temporal artery method. Blood pressure and respiratory rate were measured with the participant in a supine position after 5 minutes of rest for the participant. Clinically significant findings were determined by the investigator.

An AE was any untoward medical occurrence in a participant temporally associated with the use of study intervention, whether or not considered related to the study intervention. An SAE was defined as any untoward medical occurrence that, at any dose: resulted in death; required inpatient hospitalization or prolongation of existing hospitalization; was life-threatening; resulted in persistent or significant disability/incapacity; was a congenital anomaly/birth defect or other important medical events. An AE was considered as treatment emergent if the event started during the effective duration of treatment. All events that started on or after the first dosing day up to the last dose plus the lag time were considered as TEAEs.

An SAE was defined as any untoward medical occurrence that, at any dose: resulted in death; required inpatient hospitalization or prolongation of existing hospitalization; was life-threatening; resulted in persistent or significant disability/incapacity; was a congenital anomaly/birth defect or other important medical events. An AE was considered as treatment emergent if the event started during the effective duration of treatment.

Population: The PK parameter set consisted of all randomized participants who received at least 1 dose of study intervention and who have at least 1 of the PK parameters of interest calculated. Here, 'Overall Number of Participants Analyzed' signifies number of participants evaluable for this outcome measure and 'Number Analyzed' signifies participants evaluable for the specified time points.

Part 2: Percent Change From Baseline in Eczema Area and Severity Index (EASI) Total Score at Week 6

EASI quantifies severity of AD based on severity of lesion clinical signs and percentage (%) of body surface area (BSA) affected. Severity of clinical signs of AD lesions (erythema, induration/papulation, excoriation and lichenification) were scored separately for each of 4 body regions (head and neck, upper limbs, trunk \[including axillae and groin)\] and lower limbs \[including buttocks\]) on a 4-point scale: 0= absent; 1= mild; 2= moderate; 3= severe. EASI area score was based on % BSA with AD in body region: 0 (0%), 1 (\>0 to \<10%), 2 (10 to \<30%), 3 (30 to \<50%), 4 (50 to \<70%), 5 (70 to \<90%) and 6 (90 to 100%). Total EASI score =0.1\*Ah\*(Eh+Ih+Exh+Lh) + 0.2\*Au\*(Eu+Iu+ExU+Lu) + 0.3\*At\*(Et+It+Ext+Lt) + 0.4\*Al\*(El+Il+Exl+Ll); A = EASI area score; E = erythema; I = induration/papulation; Ex = excoriation; L = lichenification; h = head and neck; u = upper limbs; t = trunk; l = lower limbs. Total EASI score ranged from 0.0 to 72.0, with higher scores indicating greater severity of AD.

Time frame: Baseline, Week 6

Population: Modified Intention to Treat (mITT) population consisted of all randomized participants assigned to study intervention and who applied at least 1 dose of study intervention. One participant was randomized twice under different participant ID (PID) at two different sites. The participant was included in the efficacy analyses under the first PID. The participant enrolled under the second PID was included in mITT per mITT definition, but was excluded from efficacy analysis.
