Badanie doboru dawki doustnego PHA-022121 w profilaktyce napadów obrzęku naczynioruchowego u pacjentów z dziedzicznym obrzękiem naczynioruchowym typu I lub typu II (HAE CHAPTER-1)

12 sierpnia 2026 zaktualizowane przez: Pharvaris Netherlands B.V.

Badanie fazy II, z podwójnie ślepą próbą, kontrolowane placebo, randomizowane, z różnymi dawkami, w równoległych grupach, oceniające bezpieczeństwo i skuteczność PHA-022121 podawanego doustnie w profilaktyce przeciw napadom obrzęku naczynioruchowego u pacjentów z dziedzicznym obrzękiem naczynioruchowym spowodowanym niedoborem inhibitora C1 ( Typ I lub Typ II)

Niniejsze badanie ocenia bezpieczeństwo i skuteczność PHA-022121 podawanego doustnie w profilaktyce napadów obrzęku naczynioruchowego u pacjentów z dziedzicznym obrzękiem naczynioruchowym (HAE). Badanie składa się z 2 części, z pacjentami kończącymi udział w Części 1 przed rozpoczęciem leczenia w Części 2. Część 1 badania składa się z 3 równoległych ramion i około 30 pacjentów zostanie jednakowo przydzielonych losowo do jednego z dwóch schematów dawkowania PHA-022121 lub pasujące placebo. Po zakończeniu Części 1 pacjenci będą kontynuować pojedynczą grupę otwartą w Części 2 badania. Okres badań przesiewowych wynosi do 8 tygodni, a okresy leczenia wynoszą 12 tygodni (Część 1) i 50 tygodni (Część 2).

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
Ramy czasowe: 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.

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

Ramy czasowe: 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.

Ramy czasowe: Up to Day 84
Time to first investigator-confirmed HAE attack was defined as days from date of first administration of study drug until the onset date of first Investigator-confirmed HAE attack.
