- Lead Sponsor
- Pfizer
- Brief Summary
Alopecia areata (AA) is a chronic relapsing autoimmune disease characterized by nonscarring hair loss affecting children, adolescents, and adults across all ages, races, and genders.

- Sex
- All
- Target Recruitment
- 850
- Male and female patients aged >12 years at baseline.
- Patients with diagnosis of alopecia areata confirmed by a certified dermatologist, who are prescribed ritlecitinib as per the product label independently of the decision to enroll a patient in this study.
- Evidence of a personally signed and dated informed consent document indicating that the patient (or a legally acceptable representative) has been informed of all pertinent aspects of the study. Following receipt of oral and written information about the trial, the adolescent (depending on local institutional review board/independent ethics committee requirements) must provide assent, and one or both (according to local regulations) parents or guardians of the child must provide signed informed consent before any study-related activity is carried out.
- Patients, who in the opinion of the investigator, are willing and able to comply with regular clinic visits as per standard practice at the site and agree to complete PRO questionnaires and other patient completed questions.
- Diagnosed with other types of alopecia or other diseases that can cause hair loss (including, but not limited to known androgenetic alopecia, traction and scarring alopecia, telogen effluvium).
- Diagnosed with other scalp diseases that may impact AA assessment (e.g., scalp psoriasis, dermatitis, etc.) or other active systemic diseases that may cause hair loss (e.g., lupus erythematosus, thyroiditis, systemic sclerosis, lichen planus, etc.). that could interfere with assessment of hair loss/regrowth.
- Patients previously treated with ritlecitinib or other JAK inhibitors.
- Investigator site staff or Pfizer employees directly involved in the conduct of the study, site staff otherwise supervised by the investigator, and their respective family.

Group Intervention Description Alopecia Areata (AA) patients treated with ritlecitinib Ritlecitinib -
- Primary Outcome Measures
Name Time Method Percentage change from baseline in Severity of Alopecia Tool (SALT) score at week 24 24 weeks from initiation of the treatment SALT score is used to calculate the severity of alopecia areata. Physician calculate it by summing the percentage of hair loss in different regions of scalp.
- Secondary Outcome Measures
Name Time Method RW effectiveness of ritlecitinib: proportion of patient with improvement from abnormal baseline in Eyelashes Assessment Score (ELA) Week 24, 48, 72 and 96 Improvement in ELA score will indicate ritlecitinib effectiveness in eyebrow involvement.
RW effectiveness of ritlecitinib: proportion of patients with improvement from abnormal baseline in beard assessment and nail involvement week 24, 48, 72 and 96 Patient reported outcome: Evaluate ritlecitinib treatment satisfaction week 24, 48, 72 and 96 Patient-reported satisfaction (P-sat) Response (defined as slightly, moderately, or very satisfied) at 24, 48, 72 and 96 weeks
Patient reported outcome: Evaluate impression of hair growth week 24, 48, 72 and 96 Patient Global Impression of Change (PGI-C) Response (defined as a score of moderate to severe), at 24, 48, 72 and 96 weeks
Evaluate impact of ritlecitinib: Patient reported quality of life week 24, 48, 72 and 96 Change from baseline in emotional symptoms (ES) and activity limitations (AL) subscores
Demographic characteristic of participants: Age, sex, race, ethnicity, socio-economic status, area of residence, smoking status Baseline Number/percentage of patients by age, sex, race, ethnicity, socio-economic status, area of residence, smoking status. Race and ethnicity variables will only be collected in participating countries where it is allowed.
Demographic Characteristic of Participants: Date of Initial AA diagnosis Baseline Demographic Characteristics of participants: Duration of AA since diagnosis Baseline Demographic characteristics of participants: Duration of current AA Episode Baseline Demographic Characteristic of Participants: Predominant AA phenotype Baseline Predominant AA phenotype (eg, patchy; ophiasis; AT; AU, etc
Clinical Characteristics of participants: Severity of Alopecia Tool (SALT) Score Baseline SALT score is used to calculate the severity of alopecia areata.
Clinical characteristics of participants: Eyelash Assessment (ELA) score Baseline ELA score is used to calculate the severity of the involvement of eyelashes.
Clinical Characteristics of participants: Eyebrow Assessment (EBA) Score Baseline EBA score is used to calculate the severity of the involvement of eyebrows
Clinical Characteristics of participants: number of affected nails Baseline Clinical Characteristics of participants: Presence of Beard involvement Baseline Determine whether the beard is affected or not.
AA treatment history of participants: number of patients with prior AA treatments Baseline AA treatment history of participants: prior AA treatment class and route Baseline AA treatment history of participants: duration of prior therapy / frequency baseline AA treatment history of the participants: total number of prior AA treatments Baseline RW effectiveness of ritlecitinib: proportion of patients with <20 in SALT score week 24, 48, 72 and 96 decrease in SALT score is the indicator of effectiveness.
RW effectiveness of ritlecitinib: Proportion of patients with <10 week 24, 48, 72 and 96 Decrease in SALT score is the indicator of effectiveness
RW effectiveness of ritlecitinib: Change from baseline in SALT score week 24, 48, 72 and 96 Decrease in SALT score is the indicator of effectiveness
RW effectiveness of ritlecitinib: proportion of patient with improvement from abnormal baseline in Eyebrow Assessment score (EBA) Week 24, 48, 72 and 96 Improvement in EBA score will indicate ritlecitinib effectiveness in eyebrow involvement.
