Studio di dose-ranging di PHA-022121 orale per la profilassi contro gli attacchi di angioedema in pazienti con angioedema ereditario di tipo I o di tipo II (HAE CHAPTER-1)

12 agosto 2026 aggiornato da: Pharvaris Netherlands B.V.

Uno studio di fase II, in doppio cieco, controllato con placebo, randomizzato, a dosaggio variabile, a gruppi paralleli per valutare la sicurezza e l'efficacia di PHA-022121 somministrato per via orale per la profilassi contro gli attacchi di angioedema in pazienti con angioedema ereditario dovuto a carenza di C1-inibitore ( Tipo I o Tipo II)

Questo studio valuta la sicurezza e l'efficacia di PHA-022121 somministrato per via orale per la profilassi contro gli attacchi di angioedema in pazienti con angioedema ereditario (HAE). Lo studio è composto da 2 parti, con i pazienti che completano la partecipazione alla Parte 1 prima dell'inizio del trattamento nella Parte 2. La Parte 1 dello studio ha 3 bracci paralleli e circa 30 pazienti saranno ugualmente randomizzati a uno dei due regimi posologici di PHA-022121 o placebo corrispondente. I pazienti continueranno al braccio singolo in aperto nella Parte 2 dello studio dopo il completamento della Parte 1. Il periodo di screening è fino a 8 settimane e i periodi di trattamento hanno una durata di 12 settimane (Parte 1) e 50 settimane (Parte 2).

Cosa sta misurando lo studio?

Misure di risultato primarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Number of Investigator-confirmed Hereditary Angioedema (HAE) Attacks (Expressed as the Normalized Number of Attacks Per Month [4 Weeks] of Exposure) During the Treatment Period in Part 1
Lasso di tempo: Up to Day 84
HAE attack was defined as signs or symptoms in ≥1 location: peripheral angioedema (cutaneous swelling involving an extremity, face, neck, torso, and/or genitourinary region), abdominal angioedema (abdominal pain with or without abdominal distension, nausea, vomiting, or diarrhea), or upper airway angioedema (lump sensation, difficulty swallowing, throat tightening, difficulty speaking, hoarseness, stridor, dyspnea, or swelling of tongue, palate, uvula, or larynx). A new attack was counted if symptoms occurred ≥24 hours after complete resolution of a prior attack. Attacks were recorded via daily electronic patient-reported outcome (ePRO) diaries and confirmed by the investigator. Monthly attack rate was calculated as number of attacks during treatment divided by treatment days, multiplied by 28. Mean rate ratio, confidence interval (CI), and p-value were estimated using a generalized linear model with Poisson distribution, with baseline attack rate included as a factor.
Up to Day 84

Misure di risultato secondarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Number of Investigator-confirmed Moderate or Severe HAE Attacks During the Treatment Period in Part 1
Lasso di tempo: Up to Day 84
HAE attack was defined as signs or symptoms in ≥1 location: peripheral angioedema (cutaneous swelling involving an extremity, face, neck, torso, and/or genitourinary region), abdominal angioedema (abdominal pain with or without abdominal distension, nausea, vomiting, or diarrhea), or upper airway angioedema (lump sensation, difficulty swallowing, throat tightening, difficulty speaking, hoarseness, stridor, dyspnea, or swelling of tongue, palate, uvula, or larynx). A new attack was counted if symptoms occurred ≥24 hours after complete resolution of a prior attack. Attacks were recorded via daily ePRO diaries and confirmed by the investigator. Monthly attack rate was calculated as number of attacks during treatment divided by treatment days×28. Moderate HAE attack defined as which limits/interferes with the participant's ability to attend work/school or participate in family life and social/recreational activities whereas Severe HAE attack significantly limits the participant's ability.
Up to Day 84
Number of Investigator-confirmed HAE Attacks Requiring Acute Treatment During the Treatment Period in Part 1
Lasso di tempo: Up to Day 84
HAE attack was defined as signs or symptoms in ≥1 location: peripheral angioedema (cutaneous swelling involving an extremity, face, neck, torso, and/or genitourinary region), abdominal angioedema (abdominal pain with or without abdominal distension, nausea, vomiting, or diarrhea), or upper airway angioedema (lump sensation, difficulty swallowing, throat tightening, difficulty speaking, hoarseness, stridor, dyspnea, or swelling of tongue, palate, uvula, or larynx). A new attack was counted if symptoms occurred ≥24 hours after complete resolution of a prior attack. Attacks were recorded via daily ePRO diaries and confirmed by the investigator. Monthly attack rate was calculated as number of attacks during treatment divided by treatment days, multiplied by 28.
Up to Day 84
Number of Participants Achieving ≥50%, ≥70% and ≥90% Reduction in Attack Rate Relative to Baseline During the Treatment Period in Part 1
Lasso di tempo: Up to Day 84
Baseline attack rate was defined as each participant's normalized HAE attack rate (attacks per 4 weeks) prior to randomization, based on documented history or confirmed during screening. Monthly attack rate was calculated as number of attacks during treatment divided by treatment days, multiplied by 28. Percent reduction from baseline was calculated for each participant by comparing the normalized treatment-period attack rate to the baseline attack rate. Participants were classified as responders if they achieved ≥50%, ≥70%, or ≥90% reduction in attack rate relative to baseline during Part 1.
Up to Day 84
Number of Participants Who Were Investigator-confirmed Attack-free During the Treatment Period in Part 1
Lasso di tempo: Up to Day 84
HAE attack was defined as signs or symptoms in ≥1 location: peripheral angioedema (cutaneous swelling involving an extremity, face, neck, torso, and/or genitourinary region), abdominal angioedema (abdominal pain with or without abdominal distension, nausea, vomiting, or diarrhea), or upper airway angioedema (lump sensation, difficulty swallowing, throat tightening, difficulty speaking, hoarseness, stridor, dyspnea, or swelling of tongue, palate, uvula, or larynx). A new attack was counted if symptoms occurred ≥24 hours after complete resolution of a prior attack. Attacks were recorded via daily ePRO diaries and confirmed by the investigator. Participants reporting no confirmed attacks over the treatment period were considered attack-free.
Up to Day 84
Number of Days With Investigator-confirmed HAE Symptoms During the Treatment Period in Part 1
Lasso di tempo: Up to Day 84
HAE attack was defined as signs or symptoms in ≥1 location: peripheral angioedema (cutaneous swelling involving an extremity, face, neck, torso, and/or genitourinary region), abdominal angioedema (abdominal pain with or without abdominal distension, nausea, vomiting, or diarrhea), or upper airway angioedema (lump sensation, difficulty swallowing, throat tightening, difficulty speaking, hoarseness, stridor, dyspnea, or swelling of tongue, palate, uvula, or larynx). HAE symptom days were identified from daily participant entries in the ePRO diary and were confirmed by the investigator.
Up to Day 84

Lasso di tempo: Up to Day 84
HAE attack was defined as signs or symptoms in ≥1 location: peripheral angioedema (cutaneous swelling involving an extremity, face, neck, torso, and/or genitourinary region), abdominal angioedema (abdominal pain with or without abdominal distension, nausea, vomiting, or diarrhea), or upper airway angioedema (lump sensation, difficulty swallowing, throat tightening, difficulty speaking, hoarseness, stridor, dyspnea, or swelling of tongue, palate, uvula, or larynx). HAE symptom days were identified from daily participant entries in the ePRO diary and were confirmed by the investigator.

HAE attack was defined as signs or symptoms in ≥1 location: peripheral angioedema (cutaneous swelling involving an extremity, face, neck, torso, and/or genitourinary region), abdominal angioedema (abdominal pain with or without abdominal distension, nausea, vomiting, or diarrhea), or upper airway angioedema (lump sensation, difficulty swallowing, throat tightening, difficulty speaking, hoarseness, stridor, dyspnea, or swelling of tongue, palate, uvula, or larynx). A new attack was counted if symptoms occurred ≥24 hours after complete resolution of a prior attack. Attacks were recorded via daily ePRO diaries and confirmed by the investigator. Monthly attack rate was calculated as number of attacks during treatment divided by treatment days, multiplied by 28.
