Study Endpoints

Primary Endpoints

Percent Change From Baseline in Eczema Area and Severity Index (EASI) Total Score at Week 6 for AD Participants
Baseline, Week 6

EASI evaluated severity of participants' AD (excluded scalp, palms, soles) based on severity of AD clinical signs and % of body surface area (BSA) affected. Severity of clinical signs of AD (erythema, induration/papulation, excoriation and lichenification) scored separately for each of 4 body regions (head and neck, upper limbs, trunk \[including axillae and groin\] and lower limbs \[including buttocks\]) on 4-point scale: 0= absent; 1= mild; 2= moderate; 3= severe. EASI area score was based upon % 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, higher scores = greater severity of AD.

Change From Baseline in Psoriasis Area and Severity Index (PASI) Score at Week 6 for Plaque Psoriasis Participants
Baseline, Week 6

Combined assessment of lesion severity and area affected into single score. Body was divided into 4 sections: head, arms, trunk, legs. For each section, percent area of skin involved was estimated: 0= 0% to 6= 90-100%. Severity was estimated by clinical signs: erythema, induration, desquamation; scale: 0= none to 4= maximum. Final PASI = sum of severity parameters for each section\*area score\*weight of section (head: 0.1, arms: 0.2, body: 0.3, legs: 0.4); total possible score range: 0= no disease to 72= maximal disease, where higher scores = greater severity of psoriasis.

Frequently asked questions about PF-07038124

What is PF-07038124?

PF-07038124 is an investigational small molecule being developed by Pfizer, Inc. as a topical ointment for atopic dermatitis. It is in Phase 2 clinical development. Pfizer is also studying the ointment in plaque psoriasis. It is not yet approved for any indication.

What is PF-07038124 used for in atopic dermatitis?

PF-07038124 ointment is being studied as a topical treatment for atopic dermatitis, a chronic inflammatory skin condition. It is investigational and has not been approved for marketing. Pfizer evaluated it in a Phase 2 trial that enrolled adults with atopic dermatitis or plaque psoriasis.

Who makes PF-07038124?

Pfizer, Inc. (ticker PFE) is developing PF-07038124. The company sponsored both clinical trials of the topical ointment, including the Phase 2 study in atopic dermatitis and plaque psoriasis and an earlier Phase 1 study in healthy participants.

What phase is PF-07038124 in?

PF-07038124 is in Phase 2 development. Two trials have been completed: a Phase 2 study in atopic dermatitis and plaque psoriasis, and a Phase 1 study in healthy participants. No active trials are currently listed, and the drug is not approved.

What clinical trials is PF-07038124 in?

PF-07038124 has been tested in two completed trials. NCT04664153 was a Phase 2 study of the ointment in 104 adults with atopic dermatitis or plaque psoriasis across the United States, Australia, Canada, and Poland. NCT04135560 was a Phase 1 safety and pharmacokinetics study in 34 healthy participants in the United States.

Is PF-07038124 the same as PF-07038124 ointment?

Yes, PF-07038124 ointment is the same asset as PF-07038124. The ointment refers to the topical formulation of the small molecule that Pfizer is developing for atopic dermatitis. Both names describe the same investigational drug candidate.
