    E.3Principal inclusion criteria
    Each patient must meet the following criteria to be enrolled in this study. 1. Male or female patients aged = 18 to = 75 years at screening.
    2. Diagnosis of HAE (type I or II) based upon all of the following:
    a. Documented clinical history consistent with HAE (subcutaneous and/or mucosal swelling without accompanying wheals)
    b. At least one of the following: - Age at reported onset of first angioedema symptoms = 30 years
    - Family history consistent with HAE type I or II
    - C1q within normal range
    c. Diagnostic testing results to confirm HAE type I or II: - C1-INH functional level < 50% of the normal level.
    The diagnosis may be established by local laboratory values documented in the medical records or by genotyping of the C1-INH gene (SERPING1). Prior to randomization, the diagnosis needs to be confirmed by a central laboratory assessment.
    3. Documented history of at least 3 HAE attacks within the last 3 consecutive months prior to screening. If the patient has no documentation or has less than 3 attacks in the 3 months before the screening visit, or was on prophylactic treatment, patient must experience a minimum of 2 HAE attacks during the screening period (up to 8 weeks).
    4. Is assessed by the investigator to have reliable access and ability to use standard of care treatments alone to effectively manage acute HAE attacks.
    5. Body weight of = 40 kg at screening.
    6. Investigator considers that the patient is willing and able to adhere to all protocol requirements, including being capable of and compliant with data recording into an electronic Patient Reported Outcome (ePRO) tool.
    7. Female patients of childbearing potential must agree to be sexually abstinent if sexual abstinence is their usual lifestyle choice. If sexual abstinence is not their usual lifestyle choice, the use of medically acceptable and highly effective forms of contraception methods must be used from enrollment through the end of the study1 (1 Use of a male condom with or without spermicide or cervical cap, diaphragm or sponge with spermicide or a combination (double-barrier methods) is not considered highly effective.). This includes progestin-only oral contraceptive associated with inhibition of ovulation (oral, injectable, or implantable), intrauterine device (IUD, all types) or intrauterine hormone releasing systems (IUS). A female of childbearing potential whose male partner has had a vasectomy must agree to use one additional form of medically acceptable contraception (e.g., barrier method). Females of non-childbearing potential, defined as surgically sterile (status post-hysterectomy, bilateral oophorectomy, or bilateral tubal ligation) or post-menopausal women (defined as 12 consecutive months of amenorrhea without an alternative medical cause and confirmed by follicle-stimulating hormone [FSH] testing) do not require contraception use during the study.
    8. Male patients who have a female partner of childbearing potential, must agree to be sexually abstinent or use a medically acceptable form of barrier contraception (e.g., condoms) for the duration of the study and for 90 days after the last administration of study drug, if their female partners are using a medically acceptable and highly effective method of birth control. Males patients who are surgically sterile (post-vasectomy) and have a female partner of childbearing potential, must agree to be sexually abstinent or use a medically acceptable form of barrier contraception for the duration of the study, and for 90 days after the last administration of study drug. In addition, they must agree to not donate sperm during study participation and within 90 days after the last administration of study drug.
    9. The patient has provided informed consent.
    Ogni paziente deve soddisfare i seguenti criteri per essere arruolato in questo studio.
    1. Pazienti maschi o femmine di età compresa tra =>18 e <= 75 anni allo screening.
    2. Diagnosi di AEE (tipo I o II) basata su quanto segue:
    A. Anamnesi clinica documentata coerente con AEE (gonfiore sottocutaneo e/o mucoso senza pomfi di accompagnamento)
    B. Almeno uno dei seguenti:
    - Età all'esordio segnalato dei primi sintomi di angioedema =< 30 anni
    - Storia familiare coerente con AEE di tipo I o II
    - C1q nel range di normalità
    C. Risultati dei test diagnostici per confermare AEE di tipo I o II: Livello funzionale C1-INH < 50% del livello normale.
    La diagnosi può essere stabilita da valori di laboratorio locali documentati nelle cartelle cliniche o dalla genotipizzazione del gene C1-INH (SERPING1). Prima della randomizzazione, la diagnosi deve essere confermata da una valutazione di laboratorio centrale.
    3. Storia documentata di almeno 3 attacchi di AEE negli ultimi 3 mesi consecutivi prima dello screening. Se il paziente non ha documentazione o ha meno di 3 attacchi nei 3 mesi precedenti la visita di screening, o era in trattamento profilattico, il paziente deve sperimentare un minimo di 2 attacchi di AEE durante il periodo di screening (fino a 8 settimane).
    4. Lo sperimentatore valuta che disponga di un accesso affidabile e della capacità di utilizzare da soli i trattamenti standard di cura per gestire efficacemente gli attacchi di AEE acuti.
    5. Peso corporeo di = >40 kg allo screening.
    6. Lo sperimentatore ritiene che il paziente sia disposto e in grado di aderire a tutti i requisiti del protocollo, inclusa la capacità e la conformità con la registrazione dei dati in uno strumento elettronico Patient Reported Outcome (ePRO).
    7. Le pazienti in età fertile devono accettare di essere sessualmente astinenti se l'astinenza sessuale è la loro scelta di vita abituale. Se l'astinenza sessuale non è la loro scelta di vita abituale, l'uso di metodi contraccettivi clinicamente accettabili e altamente efficaci deve essere utilizzato dall'iscrizione fino alla fine dello studio1 (1 Uso di un preservativo maschile con o senza spermicida o cappuccio cervicale, diaframma o spugna con spermicida o una combinazione (metodi a doppia barriera) non è considerata altamente efficace.). Ciò include il contraccettivo orale a base di solo progestinico associato all'inibizione dell'ovulazione (orale, iniettabile o impiantabile), del dispositivo intrauterino (IUD, tutti i tipi) o dei sistemi di rilascio dell'ormone intrauterino (IUS). Una donna in età fertile il cui partner maschio ha subito una vasectomia deve accettare di utilizzare una forma aggiuntiva di contraccezione clinicamente accettabile (ad esempio, metodo di barriera). Donne in età non fertile, definite chirurgicamente sterili (stato post-isterectomia, ovariectomia bilaterale o legatura delle tube bilaterale) o donne in post-menopausa (definite come 12 mesi consecutivi di amenorrea senza una causa medica alternativa e confermata dall'ormone follicolo-stimolante [FSH]) non richiedono l'uso di contraccettivi durante lo studio.
    8. I pazienti di sesso maschile che hanno una partner femminile in età fertile devono accettare di essere sessualmente astinenti o utilizzare una forma contraccettiva di barriera accettabile dal punto di vista medico (ad es. preservativo) per la durata dello studio e per 90 giorni dopo l'ultima somministrazione del farmaco in studio , se le loro partner utilizzano un metodo contraccettivo clinicamente accettabile e altamente efficace. I pazienti di sesso maschile che sono chirurgicamente sterili (post-vasectomia) e hanno una partner femminile in età fertile, devono accettare di essere sessualmente astinenti o utilizzare una forma clinicamente accettabile di contraccezione di barriera per la durata dello studio e per 90 giorni dopo l'ultima somministrazione del farmaco in studio.

    4. Ricevere un trattamento profilattico per AEE. I pazienti che hanno ricevuto in precedenza una terapia profilattica ma l'hanno interrotta, possono partecipare a questo studio a condizione che venga osservato un periodo di washout sufficientemente lungo prima che il paziente venga sottoposto a screening. Per i pazienti che ricevono qualsiasi forma di sostituzione di C1-INH, vi è l'ulteriore restrizione che l'ultima dose prima del test di conferma C1-INH deve essere somministrata almeno 5 emivite prima della data di campionamento. L'esclusione include l'uso di:

    E.5.2.1Timepoint(s) of evaluation of this end point
    The safety endpoints will be summarized using the Safety population.
    Usage of concomitant medications (other than rescue medications) will be summarized descriptively for each of the treatment groups and the combined active treatment group.
    Clinical laboratory data, vital signs, and physical examination data will be presented in summary tables and individual listings.
    Other endpoints evaluated during the study:
    • Pharmacokinetic parameters based on plasma concentration of PHA-022121 - determined using an existing population PK model for PHA-022121
    • Change from baseline in the total AE-QoL questionnaire at Week 12
    • PGA-QoL and PGA-change questions
    • AECT-4wk scores
    • TSQM scores
    Gli endpoint di sicurezza verranno riepilogati utilizzando la popolazione Safety.
    L'uso di farmaci concomitanti (diversi dai farmaci di salvataggio) sarà riassunto in modo descrittivo per ciascuno dei gruppi di trattamento e per il gruppo di trattamento attivo combinato.
    I dati clinici di laboratorio, i segni vitali ei dati dell'esame obiettivo saranno presentati in tabelle riassuntive ed elenchi individuali.
    Altri endpoint valutati durante lo studio:
    • Parametri farmacocinetici basati sulla concentrazione plasmatica di PHA-022121 - determinati utilizzando un modello farmacocinetico di popolazione esistente per PHA-022121
    • Modifica rispetto al basale nel questionario AE-QoL totale alla settimana 12
    • Domande PGA-QoL e PGA-change
    • Punteggi AECT-4 settimane
    • Punteggi TSQM
