Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

  • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).

    The EU Clinical Trials Register currently displays   43889   clinical trials with a EudraCT protocol, of which   7298   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).  
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.3Principal inclusion criteria
    Inclusion Criteria for De Novo Participants and Those Originating from B7931005 or B7981015 with >30 Days between the Index Study and Study B7981032
    1.Participants must meet the following AA criteria:
    •Have a clinical diagnosis of AA with no other etiology of hair loss (including, but not limited to traction and scarring alopecia, telogen effluvium). Androgenetic alopecia coexistent with AA is allowed provided that the following criteria are met;
    •De novo participants ≥12 to <18 years of age: ≥50% terminal scalp hair loss due to AA (including AT and AU), as measured by SALT, at both screening and Day 1 which, in opinion of investigator, is appropriate for systemic therapy;
    •De novo participants ≥18 years of age and participants from B7931005 or B7981015 with >30 days between index study and Study B7981032: ≥25% terminal scalp hair loss due to AA (including AT and AU), as measured by SALT, at both screening and Day 1 which, in the opinion of the investigator, is appropriate for systemic therapy;
    •Hair loss must be carefully reviewed to verify required percentage of terminal scalp hair loss is due to AA (ie, SALT (AA) score is >=25%) or ≥50%, as applicable). If, in cases of concomitant AA and androgenetic alopecia, it cannot be verified that the participant has the required SALT (AA) score then the participant must be excluded from the study.
    •No evidence of terminal scalp hair regrowth within 6 months of both screening and Day 1 (de novo participants only);
    •Current episode of terminal scalp hair loss due to AA =<10 years (de novo participants only);
    Inclusion Criteria for All Participants Originating from B7931005 or B7981015
    2.Participants enrolling from Study B7931005 must have taken the last dose of PF-06700841 in Study B7931005 >12 weeks prior to the Study B7981032 Day 1 visit.
    3.Participants enrolling from Study B7981015 must have completed >=34 weeks of study intervention.
    Inclusion Criteria for All Participants
    4.All participants must be >=12 years of age. Participants <18 years of age will only be enrolled if permitted by the sponsor, local competent authority, and institutional review board (IRB)/ethics committee (EC). Otherwise, only participants >=18 years (or age by applicable reviewer) will be enrolled in those countries, regions or sites. Within the EU, subjects must be aged 18 through 74 years. Within UK, participants must be 18 years of age or older.
    5.Male or Female
    For all participants contraceptive use by men or women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies.
    a.Male participants: No contraceptive measures required.
    b.Female participants:
    •A female participant is eligible to participate if she is not pregnant or breastfeeding, and at least one of the following conditions applies:
    •Is not a woman of childbearing potential (WOCBP), See Appendix 4.
    •Is a WOCBP and using a contraceptive method that is highly effective, with a failure rate of <1%, as described in Appendix 4 during the intervention period and for at least 28 days after the last dose of study intervention. The investigator should evaluate the effectiveness of the contraceptive method in relationship to the first dose of study intervention.
    •A WOCBP must have a negative highly sensitive (Appendix 2) pregnancy test (urine or serum as required by local regulations) at the Day 1 visit before the first dose of study intervention.
    •If a urine test cannot be confirmed as negative (eg, an ambiguous result), a serum pregnancy test is required. In such cases, the participant must be excluded from participation if the serum pregnancy result is positive.
    •The investigator is responsible for review of medical history, menstrual history, and recent sexual activity to decrease the risk for inclusion of a woman with an early undetected pregnancy
    6.All participants must be capable of giving signed informed consent/assent as described in Appendix 1 which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol.
    7.All participants must be willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures.
    8.If receiving permitted concomitant medications for any reason other than AA, participants should be on a stable regimen, which is defined as not starting a new drug or changing dosage within 7 days or 5 half-lives (whichever is longer) prior to Day 1. Participants must be willing to stay on a stable regimen during the duration of the study (see Section 6.5).
    9.All participants must agree to avoid prolonged exposure to the sun and not to use tanning booths, sun lamps or other ultraviolet light sources during the study.
    E.4Principal exclusion criteria
    Exclusion Criteria for Participants Originating from B7931005 or B7981015 with <=30 Days between Studies
    1.During Study B7931005 or B7981015 or in the period between the index study and Study B7981032, presence of safety events meeting discontinuation criteria in the Appendix 8 (eg, serious infections, laboratory results, ECG results).
    2.Discontinuation from Study B7931005 or B7981015 for safety related events. Participants discontinued from Study B7931005 or B7981015 due to issues other than safety-related events must be discussed with the sponsor prior to enrollment in Study B7981032.
    Exclusion Criteria for De Novo Participants and Those Originating from B7931005 or B7981015 with >30 Days between the Index Study and Study B7981032
    3.Other scalp disease that may impact AA assessment (eg, scalp psoriasis, dermatitis, etc).
    4.Active systemic diseases that may cause hair loss (eg, lupus erythematosus, thyroiditis, systemic sclerosis, lichen planus, etc).
    5.Any psychiatric condition including recent or active suicidal ideation or behavior that meets any of the following criteria:
    a.Suicidal ideation associated with actual intent and a method or plan in the past year: “Yes” answers on items 4 or 5 of the Columbia Suicide Severity Rating Scale (C SSRS) (Section 8.2.9).
    b.For participants who had previous history of suicidal behaviors in the past >1 year to <5 years: “Yes” answer (for events that occurred in the past 5 years) to any of the suicidal behavior items of the C SSRS or any lifetime history of serious or recurrent suicidal behavior, a risk assessment must be performed, and documented, by a qualified mental health professional to assess whether it is safe for the participant to participate in the trial.
    c.The presence of any current major psychiatric disorder that is not explicitly permitted in the inclusion/exclusion criteria.
    d.Clinically significant depression as indicated by a Patient Health Questionnaire 8 Items (PHQ 8) total score >=15 (Section 8.2.10).
