Dosisfindungsstudie zu oralem PHA-022121 zur Prophylaxe gegen Angioödem-Attacken bei Patienten mit hereditärem Angioödem Typ I oder Typ II (HAE CHAPTER-1)

12. August 2026 aktualisiert von: Pharvaris Netherlands B.V.

Eine doppelblinde, Placebo-kontrollierte, randomisierte Parallelgruppen-Dosisfindungsstudie der Phase II zur Bewertung der Sicherheit und Wirksamkeit von oral verabreichtem PHA-022121 zur Prophylaxe gegen Angioödem-Attacken bei Patienten mit hereditärem Angioödem aufgrund von C1-Inhibitor-Mangel ( Typ I oder Typ II)

Diese Studie bewertet die Sicherheit und Wirksamkeit von oral verabreichtem PHA-022121 zur Prophylaxe gegen Angioödem-Attacken bei Patienten mit hereditärem Angioödem (HAE). Die Studie besteht aus 2 Teilen, wobei die Patienten die Teilnahme an Teil 1 vor Beginn der Behandlung in Teil 2 abschließen. Teil 1 der Studie hat 3 parallele Arme und ungefähr 30 Patienten werden zu gleichen Teilen randomisiert einem von zwei Dosierungsschemata von PHA-022121 zugeteilt oder passendes Placebo. Die Patienten werden nach Abschluss von Teil 1 mit dem einzelnen offenen Arm in Teil 2 der Studie fortfahren. Der Screening-Zeitraum beträgt bis zu 8 Wochen und die Behandlungszeiträume 12 Wochen (Teil 1) und 50 Wochen (Teil 2).

Zeitfenster
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
Zeitfenster: 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

Number of Investigator-confirmed Moderate or Severe HAE Attacks During the Treatment Period in Part 1
Zeitfenster: 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
Zeitfenster: 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
Zeitfenster: 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
Zeitfenster: 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.
